Description

Domaine techniqueTechnical area

La présente invention se rapporte à un dispositif et à un procédé de réglage du positionnement en hauteur d'un véhicule équipé de roues ou comportant des éléments de roulement cylindriques sur un plateau de chargement.The present invention relates to a device and a method for adjusting the height positioning of a vehicle equipped with wheels or comprising cylindrical rolling elements on a loading platform.

L'invention concerne plus particulièrement un dispositif et un procédé de réglage du positionnement en hauteur d'une semi-remorque par ses roues sur un plateau ou une poche de chargement d'un wagon ferroviaire.The invention relates more particularly to a device and a method for adjusting the height positioning of a semi-trailer by its wheels on a platform or a loading pocket of a railway wagon.

Etat de la techniqueState of the art

Par le brevet FR 2960843 on connait un dispositif de réglage de hauteur de la partie la plus basse d'un wagon de type poche principalement en fonction du poids de la charge à transporter et de l'état d'usure des bogies du wagon de manière à obtenir pour chaque charge un niveau bas quasi constant de la partie basse de la poche. Ce dispositif de réglage de hauteur repose sur la mise en place de cales verticales entre la poche et les ensembles d'extrémités sur lesquels repose ladite poche, notamment dans le but de positionner la partie basse de la poche au niveau le plus bas admissible compte tenu du gabarit ferroviaire.By the patent EN 2960843 there is known a device for adjusting the height of the lowest part of a pocket-type wagon mainly as a function of the weight of the load to be transported and the state of wear of the bogies of the wagon so as to obtain for each load an almost constant low level of the lower part of the pocket. This height adjustment device is based on the placement of vertical wedges between the pocket and the sets of ends on which said pocket rests, in particular with the aim of positioning the lower part of the pocket at the lowest admissible level taking into account of the railway gauge.

Ce procédé de réglage n'est cependant pas adapté à tous les types de wagon ferroviaire et ne permet pas de régler le positionnement en hauteur d'un véhicule par rapport au plateau de chargement sur lequel il repose. Il nécessite en outre un moyen de manutention adapté pour lever la poche par rapport aux ensembles extrémités.However, this adjustment method is not suitable for all types of railway wagon and does not make it possible to adjust the height positioning of a vehicle relative to the loading platform on which it rests. It also requires suitable handling means to lift the ladle relative to the end assemblies.

Il est également connu d'utiliser des cales amovibles sur un véhicule porte-voitures, lesdites cales étant immobilisées selon des positions choisies sur le plateau de chargement du véhicule porte-voitures de sorte que les roues des véhicules routiers transportés sur le véhicule porte-voitures soient au moins partiellement immobilisées par leur appui sur ces cales.It is also known to use removable chocks on a car carrier vehicle, said chocks being immobilized according to selected positions on the loading platform of the car carrier vehicle so that the wheels of the road vehicles transported on the car carrier vehicle are at least partially immobilized by their support on these wedges.

Ce dispositif d'immobilisation des roues d'un véhicule routier par des cales, est souvent utilisé d'un seul côté des roues et combiné avec d'autres dispositifs d'immobilisation, par exemple de type sangle, pour immobiliser totalement les roues du véhicule routier afin de sécuriser ce dernier sur le véhicule porte-voitures. Ainsi, ces cales ne sont généralement pas utilisées par paire. En outre, ces cales ne sont en aucune manière prévues pour régler la hauteur des véhicules transportés sur le véhicule porte-voitures et elles ne sont jamais utilisées pour cette fonction dans le cadre du transport d'un véhicule routier sur un wagon ferroviaire.This device for immobilizing the wheels of a road vehicle by wedges, is often used on one side of the wheels only and combined with other immobilizing devices, for example of the strap type, to completely immobilize the wheels of the vehicle. road in order to secure it on the car transport vehicle. Thus, these wedges are generally not used in pairs. In addition, these wedges are in no way intended to adjust the height of the vehicles transported on the car transport vehicle and they are never used. for this function in the context of the transport of a road vehicle on a railway wagon.

Par le brevet FR 1472098 on connait un wagon ferroviaire surbaissé à plancher central élévateur mobile pour le chargement de véhicules par les extrémités du châssis roulant. Le plancher central élévateur mobile permet de faire circuler temporairement lesdits véhicules à la même hauteur que les extrémités du châssis roulant avant de s'abaisser, mais ne s'intéresse pas à l'immobilisation ou au réglage individuel en hauteur des roues desdits véhicules.By the patent FR 1472098 We know a lowered railway wagon with a movable central lifting floor for loading vehicles by the ends of the rolling frame. The mobile lifting central floor makes it possible to circulate said vehicles temporarily at the same height as the ends of the rolling frame before lowering, but is not concerned with the immobilization or the individual adjustment in height of the wheels of said vehicles.

Par le brevet DE 1207949 on connait un wagon ferroviaire dont le plancher central comprend deux parties inclinables vers le bas, mais celui ne s'intéresse pas non plus à l'immobilisation ou au réglage individuel en hauteur des roues des véhicules chargés sur le plancher central.By the patent DE 1207949 We know a railway car whose central floor comprises two parts tilting downwards, but that is not interested either in the immobilization or in the individual height adjustment of the wheels of the vehicles loaded on the central floor.

Description de l'inventionDescription of the invention

L'objet de la présente invention vise par conséquent à pallier les inconvénients de l'art antérieur en proposant un nouveau dispositif et un nouveau procédé de réglage du positionnement en hauteur d'un véhicule équipé de roues sur un plateau de chargement qui peut être adapté à tout type de wagon ferroviaire, et qui est susceptible d'être actionné uniquement par le seul usage de la force humaine.The object of the present invention therefore aims to overcome the drawbacks of the prior art by proposing a new device and a new method for adjusting the height positioning of a vehicle equipped with wheels on a loading platform which can be adapted to any type of railway wagon, and which is capable of being operated solely by the sole use of human power.

Avantageusement, la présente invention doit permettre d'assurer une distance optimale et quasi constante entre le sol et la partie inférieure la plus basse du véhicule routier transporté ou du plateau/de la poche de chargement de wagon ferroviaire supportant ledit véhicule routier, principalement en fonction du poids de la charge à transporter et de l'état d'usure des bogies du wagon. Cette distance est la plus faible possible compte tenu des limitations provenant des formes de la partie basse précédente et de celles liées au gabarit ferroviaire.Advantageously, the present invention must make it possible to ensure an optimal and almost constant distance between the ground and the lowest lower part of the transported road vehicle or of the rail wagon loading platform/pocket supporting said road vehicle, mainly as a function of the weight of the load to be transported and the state of wear of the bogies of the wagon. This distance is as small as possible given the limitations resulting from the shapes of the previous lower part and those related to the railway gauge.

Un autre objet de la présente invention est de permettre de régler la hauteur de la partie la plus haute de la charge d'un wagon ferroviaire à un niveau haut quasi constant. Dans le cas du transport de véhicules routiers, la présente invention doit aussi permettre de placer la partie haute des véhicules routiers à une hauteur quasi constante, quel que soit l'état d'usure des bogies du wagon et le poids de la charge à transporter.Another object of the present invention is to make it possible to adjust the height of the highest part of the load of a railway wagon to an almost constant high level. In the case of the transport of road vehicles, the present invention must also make it possible to place the upper part of the road vehicles at an almost constant height, whatever the state of wear of the bogies of the wagon and the weight of the load to be transported. .

Avantageusement, la présente invention doit s'adapter à tout type de wagon ferroviaire, notamment aux structures classique de wagon sans nécessiter de poche dissociable.Advantageously, the present invention must adapt to any type of railway wagon, in particular to conventional wagon structures without requiring a separable pocket.

Enfin, la présente invention doit avantageusement permettre le réglage du positionnement en hauteur d'un véhicule équipé de roues sur un plateau de chargement en utilisant uniquement la force humaine, et sans nécessiter de moyens de levage.Finally, the present invention should advantageously allow the adjustment of the height positioning of a vehicle equipped with wheels on a loading platform using only human power, and without requiring lifting means.

Les objets assignés à l'invention sont atteints à l'aide d'un wagon ferroviaire comportant un plateau de chargement destiné à transporter un véhicule routier équipé de roues, caractérisé en ce qu'il comprend un système de réglage du positionnement en hauteur des roues d'un véhicule routier prévu pour régler la hauteur des roues du véhicule routier à une hauteur prédéterminée par rapport au plateau de chargement avant chaque transport et pendant toute la durée de celui-ci de sorte que le véhicule routier transporté se trouve à un niveau bas qui est supérieur ou égal de la limite basse du gabarit ferroviaire tout en respectant la limite haute du gabarit ferroviaire, un système de réglage étant prévu pour chaque roue du véhicule routier, chaque système de réglage comprenant :

  • un évidement aménagé dans le plateau de chargement au niveau de l'emplacement prévu pour une roue du véhicule routier, l'évidement étant dimensionné pour permettre l'engagement au moins partiel de la roue à travers l'évidement ;
  • un dispositif de soutien pour roue monté sur le plateau de chargement au niveau de l'emplacement prévu pour la roue,
et dans lequel :
  • le dispositif de soutien est monté soit directement sur le plateau de chargement, soit par l'intermédiaire d'une plaque mobile montée réglable en position longitudinale sur le plateau de chargement ;
  • le dispositif de soutien comportant au moins une pièce de soutien mobile et/ou déformable destinée à supporter la roue par au moins une zone de contact de sorte que la roue soit portée par ladite zone de contact au niveau de l'évidement, le déplacement ou la déformation de l'au moins une pièce de soutien déplaçant verticalement la position de la zone de contact.
The objects assigned to the invention are achieved with the aid of a railway wagon comprising a loading platform intended to transport a road vehicle fitted with wheels, characterized in that it comprises a system for adjusting the height of the wheels of a road vehicle designed to adjust the height of the wheels of the road vehicle to a predetermined height relative to the loading platform before each transport and throughout the duration thereof so that the transported road vehicle is at a low level which is greater than or equal to the lower limit of the railway gauge while respecting the upper limit of the railway gauge, an adjustment system being provided for each wheel of the road vehicle, each adjustment system comprising:
  • a recess provided in the loading platform at the location provided for a wheel of the road vehicle, the recess being sized to allow at least partial engagement of the wheel through the recess;
  • a wheel support device mounted on the loading platform at the location provided for the wheel,
and in which:
  • the support device is mounted either directly on the loading platform, or via a movable plate mounted adjustable in longitudinal position on the loading platform;
  • the support device comprising at least one mobile and/or deformable support part intended to support the wheel by at least one contact zone so that the wheel is carried by said contact zone at the level of the recess, the displacement or the deformation of the at least one support piece vertically displacing the position of the contact zone.

Ainsi, en faisant varier la position de l'au moins une zone de contact il est possible de régler la position de la roue d'un véhicule routier portée sur la pièce de soutien mobile et/ou déformable au-dessus ou au travers d'un évidement aménagé dans le plateau de chargement, ce qui permet de régler la hauteur du véhicule routier par rapport au plateau de chargement. Les roues du véhicule routier pouvant pénétrer partiellement dans un évidement aménagé dans le plateau de chargement, cela permet par conséquent de régler la hauteur de la partie la plus basse d'un wagon ferroviaire en vue du transport d'un véhicule routier principalement en fonction du poids de la charge à transporter et de l'état d'usure des bogies du wagon de manière à obtenir pour chaque charge un niveau bas quasi constant de la partie basse du wagon ferroviaire.Thus, by varying the position of the at least one contact zone, it is possible to adjust the position of the wheel of a road vehicle carried on the mobile and/or deformable support part above or through a recess provided in the loading platform, which makes it possible to adjust the height of the road vehicle relative to the loading platform. Since the wheels of the road vehicle can partially penetrate into a recess provided in the loading platform, this consequently makes it possible to adjust the height of the lowest part of a railway wagon with a view to transporting a road vehicle mainly as a function of the weight of the load to be transported and the condition wear of the bogies of the wagon so as to obtain for each load an almost constant low level of the lower part of the railway wagon.

Le véhicule est maintenu et porté par toutes ses roues pour une meilleure sécurisation de celui-ci sur le wagon ferroviaire et pour une répartition éventuelle de son poids sur les différents dispositifs de soutien.The vehicle is held and carried by all its wheels for better securing of the latter on the railway wagon and for a possible distribution of its weight on the various support devices.

Avantageusement, les pièces de soutien servent non seulement au réglage en hauteur du véhicule routier, mais elles servent également à sécuriser et à maintenir le véhicule routier par ses roues sur le plateau de chargement du wagon ferroviaire.Advantageously, the support parts not only serve to adjust the height of the road vehicle, but they also serve to secure and hold the road vehicle by its wheels on the loading platform of the railway wagon.

En réglant les roues d'un même véhicule routier à des hauteurs différentes, cette invention permet avantageusement d'éventuellement changer l'angle d'inclinaison latéral et/ou longitudinal d'un véhicule routier par rapport au plateau de chargement, par rapport au wagon et/ou par rapport au sol.By adjusting the wheels of the same road vehicle to different heights, this invention advantageously makes it possible to possibly change the lateral and/or longitudinal angle of inclination of a road vehicle relative to the loading platform, relative to the wagon and/or relative to the ground.

Selon un autre exemple de réalisation de l'invention, l'au moins une pièce de soutien est amovible, ce qui permet par exemple de les retirer pour pouvoir utiliser le wagon ferroviaire pour le transport d'autres chargements ne nécessitant pas de pièce de soutien selon l'invention.According to another exemplary embodiment of the invention, the at least one support piece is removable, which makes it possible, for example, to remove them in order to be able to use the railway wagon for the transport of other loads not requiring a support piece. according to the invention.

Selon un exemple supplémentaire de réalisation de l'invention, chaque dispositif de soutien comprend deux pièces de soutien chacune sous la forme d'une cale, et :

  • au sein de chaque paire de cales, l'au moins une zone de contact est composée par une surface d'appui et de calage oblique sur chaque cale, ces surfaces d'appui et de calage obliques étant en regard l'une de l'autre ;
  • l'une au moins des cales étant déplaçable manuellement en écartement relatif longitudinal au sein de chaque paire de cales, l'autre cale pouvant être déplaçable manuellement ou fixe par rapport au plateau de chargement ou à la plaque mobile ;
  • chaque cale déplaçable comporte au moins un dispositif d'immobilisation ;
  • le plateau de chargement ou la plaque mobile comprend au moins un dispositif d'immobilisation complémentaire destiné à coopérer avec le dispositif d'immobilisation des cales déplaçables pour immobiliser lesdites cales sur le plateau de chargement ou sur la plaque mobile.
According to an additional exemplary embodiment of the invention, each support device comprises two support parts each in the form of a wedge, and:
  • within each pair of shims, the at least one contact zone is composed of an oblique support and wedging surface on each shim, these oblique support and wedging surfaces facing one of the other ;
  • at least one of the wedges being manually movable in longitudinal relative spacing within each pair of wedges, the other wedge being able to be manually movable or fixed relative to the loading platform or to the movable plate;
  • each movable chock comprises at least one immobilizing device;
  • the loading plate or the movable plate comprises at least one additional immobilizing device intended to cooperate with the device for immobilizing the movable chocks in order to immobilize said chocks on the loading plate or on the movable plate.

L'usage de cales est avantageux en ce que ces cales peuvent être positionnées manuellement sur le plateau de chargement de manière simple et rapide, leur écartement relatif au sein de chaque paire permettant de régler la hauteur des roues du véhicule routier en les laissant pénétrer plus ou moins dans l'évidement aménagé dans le plateau de chargement.The use of wedges is advantageous in that these wedges can be positioned manually on the loading platform in a simple and rapid manner, their relative spacing within each pair making it possible to adjust the height of the wheels of the road vehicle by letting them penetrate more or less in the recess in the loading platform.

L'usage de cales déplaçable est avantageux en ce qu'il permet d'adapter le dispositif de soutien de l'invention à différents empattements entre les essieux du véhicule routier.The use of movable wedges is advantageous in that it makes it possible to adapt the support device of the invention to different wheelbases between the axles of the road vehicle.

Selon un exemple de réalisation de l'invention, chaque cale présente une surface d'appui et de calage pour les roues, cette surface étant inclinée par rapport à l'horizontal d'un angle compris entre 20° et 90°, préférentiellement compris entre 35° et 60°, et plus préférentiellement sensiblement égal à 45°.According to an exemplary embodiment of the invention, each chock has a support and wedging surface for the wheels, this surface being inclined relative to the horizontal by an angle of between 20° and 90°, preferably between 35° and 60°, and more preferably substantially equal to 45°.

En effet, plus l'inclinaison est faible, plus le réglage en hauteur est fin pour un même écartement des cales, tandis que plus l'inclinaison est grande, plus le niveau d'immobilisation des roues est important, alors que des cales obliques selon un angle sensiblement égal à 45° offrent un bon compromis entre finesse de réglage en hauteur et degré d'immobilisation des roues.In fact, the lower the inclination, the finer the height adjustment for the same spacing between the chocks, while the greater the inclination, the greater the level of immobilization of the wheels, whereas oblique chocks according to an angle substantially equal to 45° offer a good compromise between fine adjustment in height and degree of immobilization of the wheels.

Ces cales se différentient des cales classiques pour voiture comportant un tube de diamètre réduit et qui sont utilisées pour les porte-voitures, ces cales classiques n'étant pas prévues pour supporter le poids d'un véhicule qui serait porté par celles-ci. En effet, le tube des cales classiques pour voiture présente un diamètre trop faible pour supporter le poids d'un véhicule, notamment lorsqu'il s'agit d'une semi-remorque, alors que les cales de l'invention sont prévues à cet effet et sont par conséquent dimensionnées et conçue pour supporter un poids très important.These chocks differ from conventional car chocks comprising a tube of reduced diameter and which are used for car carriers, these conventional chocks not being designed to support the weight of a vehicle which would be carried by them. In fact, the tube of conventional car chocks has a diameter that is too small to support the weight of a vehicle, in particular when it is a semi-trailer, whereas the chocks of the invention are provided for this purpose. effect and are therefore sized and designed to support a very heavy weight.

Selon une alternative de réalisation de l'invention, chaque dispositif de soutien comprend :

  • une pièce de soutien sous la forme d'une pièce souple ou articulée apte à se déformer pour épouser la forme de l'au moins une roue du véhicule routier qu'elle soutient ;
  • deux guides prévus à l'avant et à l'arrière de l'au moins une roue, la pièce souple ou articulée étant maintenue entre ses deux guides ; et
  • un dispositif de tension prévu pour régler la tension de la pièce souple ou articulée entre les deux guides.
According to an alternative embodiment of the invention, each support device comprises:
  • a support part in the form of a flexible or articulated part capable of deforming to match the shape of the at least one wheel of the road vehicle that it supports;
  • two guides provided at the front and at the rear of the at least one wheel, the flexible or articulated part being held between its two guides; and
  • a tensioning device provided for adjusting the tension of the flexible or articulated piece between the two guides.

L'usage d'une pièce souple ou articulée est avantageux en ce que sa tension peut être réglée manuellement de manière simple et rapide pour régler la hauteur des roues du véhicule routier en les laissant pénétrer plus ou moins dans l'évidement aménagé dans le plateau de chargement, selon que la pièce souple ou articulée est inversement plus ou moins tendue. En outre, si la largeur de la pièce souple ou articulée est égale ou supérieure à la largeur des roues, elles assurent une protection des roues par rapport aux agressions de l'environnement.The use of a flexible or articulated part is advantageous in that its tension can be adjusted manually in a simple and rapid manner to adjust the height of the wheels of the road vehicle by letting them penetrate more or less into the recess provided in the plate. loading, depending on whether the flexible or articulated part is inversely more or less stretched. In addition, if the width of the flexible or articulated part is equal to or greater than the width of the wheels, they ensure protection of the wheels with respect to attacks from the environment.

Selon un autre exemple de réalisation de l'invention, au moins une pièce souple ou articulée est sous la forme d'une corde, d'une sangle, d'un câble, d'une chaîne, de plaques articulées ou d'une combinaison de ces moyens.According to another exemplary embodiment of the invention, at least one flexible or articulated part is in the form of a rope, a strap, a cable, a chain, articulated plates or a combination of these means.

Selon un exemple supplémentaire de réalisation de l'invention, le dispositif de tension est constitué par deux guides autour desquels la pièce souple ou articulée est fixée et/ou enroulée. Ainsi, l'enroulement de la pièce souple ou articulée autour d'au moins un des guides permet de régler sa tension et de régler la hauteur des roues du véhicule routier.According to an additional embodiment of the invention, the tensioning device consists of two guides around which the flexible or articulated part is fixed and/or rolled up. Thus, the winding of the flexible or articulated part around at least one of the guides makes it possible to adjust its tension and to adjust the height of the wheels of the road vehicle.

Selon un exemple de réalisation de l'invention, le dispositif de tension comprend un dispositif à cliquet, qui est avantageusement adapté à la mise en tension et au maintien en tension, notamment manuel, d'une pièce souple ou articulée.According to an exemplary embodiment of the invention, the tensioning device comprises a ratchet device, which is advantageously suitable for tensioning and maintaining tension, in particular manually, of a flexible or articulated part.

Selon un autre exemple de réalisation de l'invention, le dispositif à cliquet comprend un levier pour son actionnement manuel.According to another exemplary embodiment of the invention, the ratchet device comprises a lever for its manual actuation.

Selon un exemple supplémentaire de réalisation de l'invention, le dispositif de tension est constitué par deux guides, et :

  • each movable guide comprises at least one immobilizing device;
  • the loading plate or the movable plate comprises at least one additional immobilizing device intended to cooperate with the device for immobilizing the movable guides in order to immobilize the said guides on the loading plate or on the movable plate.

L'usage d'au moins un guide déplaçable est avantageux en ce qu'il permet de régler rapidement et simplement la tension d'une pièce souple ou articulée et permet d'adapter le dispositif de soutien de l'invention à différents empattements entre les essieux du véhicule routier.The use of at least one movable guide is advantageous in that it makes it possible to quickly and simply adjust the tension of a flexible or articulated part and makes it possible to adapt the support device of the invention to different wheelbases between the axles of the road vehicle.

  • a pair of tightening bolts designed to engage with immobilization in an orifice or an oblong among orifices or oblongs regularly distributed in the upper face of the loading platform, in longitudinal rails integral with the upper face of the loading platform, in the upper face of the movable plate, or in longitudinal rails integral with the upper face of the movable plate.

Ces dispositifs d'immobilisation sont avantageux en ce qu'ils permettent de mettre en place et positionner rapidement et simplement des cales ou des guides, et de régler leur écartement relatif de manière simple et rapide selon des positionnements longitudinaux pré-indexés sur le plateau de chargement. Ces dispositifs d'immobilisation sont avantageusement faciles et rapides à utiliser, et fiables pour sécuriser un véhicule sur le plateau de chargement d'un véhicule ferroviaire.These immobilization devices are advantageous in that they make it possible to set up and position wedges or guides quickly and simply, and to adjust their relative spacing simply and quickly according to longitudinal positions pre-indexed on the plate of loading. These immobilizers are advantageously easy and quick to use, and reliable for securing a vehicle on the loading platform of a railway vehicle.

Selon un autre exemple de réalisation de l'invention, le plateau de chargement est une poche portée par un wagon de ferroutage de type wagon-poche ou en ce que le plateau de chargement est le plancher d'un wagon plat. En effet, l'invention peut s'appliquer à tout type de wagon ferroviaire prévu pour le transport de véhicules routiers ou de tout autre charge comportant des moyens de roulement cylindriques.According to another exemplary embodiment of the invention, the loading platform is a pocket carried by a piggyback wagon of the pocket wagon type or in that the loading platform is the floor of a flat wagon. Indeed, the invention can be applied to any type of railway wagon provided for the transport of road vehicles or any other load comprising cylindrical rolling means.

Selon une autre alternative de réalisation de l'invention, chaque dispositif de soutien comprend :

  • une pièce de soutien sous la forme sous la forme d'un réceptacle rigide prévu pour être introduit dans l'évidement du plateau de chargement et pour supporter une roue du véhicule routier ;
  • deux dispositifs de positionnement en hauteur du réceptacle rigide prévus à l'avant et à l'arrière de l'au moins une roue, le réceptacle rigide étant porté et positionné en hauteur par ces dispositifs de positionnement en hauteur.
According to another alternative embodiment of the invention, each support device comprises:
  • a support piece in the form of a rigid receptacle intended to be introduced into the recess of the loading platform and to support a wheel of the road vehicle;
  • two height positioning devices for the rigid receptacle provided at the front and at the rear of the at least one wheel, the rigid receptacle being carried and positioned in height by these height positioning devices.

Selon un exemple de réalisation de l'invention, chaque dispositif de positionnement en hauteur du réceptacle rigide comporte au moins l'un des moyens suivants :

  • une cale à degré ;
  • une came rotative ;
  • une cale biaise ;
  • une articulation par laquelle le réceptacle rigide est monté pivotant sur le plateau de chargement ou sur la plaque mobile.
According to an exemplary embodiment of the invention, each height positioning device of the rigid receptacle comprises at least one of the following means:
  • a step wedge;
  • a rotary cam;
  • an angled wedge;
  • an articulation by which the rigid receptacle is pivotally mounted on the loading platform or on the movable plate.

Selon un autre exemple de réalisation de l'invention, chaque plaque mobile présente un évidement prévu pour pouvoir être superposé au-dessus d'un évidement aménagé dans le plateau de chargement au niveau de l'emplacement prévu pour les roues du véhicule routier.According to another exemplary embodiment of the invention, each movable plate has a recess provided so as to be able to be superimposed above a recess arranged in the loading platform at the level of the location provided for the wheels of the road vehicle.

Les objets assignés à l'invention sont également atteints à l'aide d'un procédé de réglage du positionnement en hauteur d'un véhicule routier équipé de roues sur un plateau de chargement porté ou solidaire d'un wagon ferroviaire selon l'invention en vue du transport dudit véhicule sur le wagon ferroviaire, ledit procédé étant caractérisé en ce qu'il comprend les étapes successives suivantes :

  1. a) détermination de la hauteur à laquelle le véhicule routier doit être positionné pendant son transport sur le wagon ferroviaire, en fonction des variables liées au wagon à vide et en charge, pour se trouver à un niveau bas proche de la limite inférieure du gabarit ferroviaire mais sans la dépasser ;
  2. b) détermination de la hauteur à laquelle les roues du véhicule routier doivent être positionnées pour obtenir la hauteur de véhicule déterminée à l'étape a) ;
  3. c) mise en place d'au moins un dispositif de soutien sur le plateau de chargement au niveau de l'emplacement prévu pour les roues du véhicule routier ;
  4. d) réglage de la position ou de la conformation d'au moins une pièce de soutien pour que la hauteur de roue déterminée à l'étape b) soit obtenue lorsqu'une roue du véhicule routier repose sur cette pièce de soutien ;
  5. e) immobilisation de l'au moins une pièce de soutien sur le plateau de chargement selon la position ou la conformation réglée à l'étape d) ;
  6. f) chargement du véhicule routier sur le plateau de chargement en plaçant une de ses roues sur l'au moins une pièce de soutien immobilisée à l'étape e).
The objects assigned to the invention are also achieved using a method for adjusting the height positioning of a road vehicle equipped with wheels on a loading platform carried or secured to a railway wagon according to the invention in view of the transport of said vehicle on the railway wagon, said method being characterized in that it comprises the following successive steps:
  1. a) determination of the height at which the road vehicle must be positioned during its transport on the railway wagon, according to the variables linked to the empty and laden wagon, to be at a low level close to the lower limit of the railway gauge but without exceeding it;
  2. b) determination of the height at which the wheels of the road vehicle must be positioned to obtain the vehicle height determined in step a);
  3. c) installation of at least one support device on the loading platform at the location provided for the wheels of the road vehicle;
  4. d) adjusting the position or the conformation of at least one support piece so that the wheel height determined in step b) is obtained when a wheel of the road vehicle rests on this support piece;
  5. e) immobilization of the at least one support piece on the loading platform according to the position or the conformation set in step d);
  6. f) loading the road vehicle onto the loading platform by placing one of its wheels on the at least one support piece immobilized in step e).

Ce procédé permet de régler rapidement et facilement la position de la roue d'un véhicule routier par rapport au plateau de chargement, et par conséquent de régler la hauteur de la roue en vue du transport d'un véhicule routier principalement en fonction du poids de la charge à transporter et de l'état d'usure des bogies du wagon de manière à obtenir pour chaque charge un niveau bas quasi constant de la partie basse du wagon ferroviaire et de son chargement.This method makes it possible to quickly and easily adjust the position of the wheel of a road vehicle relative to the loading platform, and consequently to adjust the height of the wheel with a view to transporting a road vehicle mainly as a function of the weight of the load to be transported and the state of wear of the bogies of the wagon so as to obtain for each load an almost constant low level of the lower part of the railway wagon and its load.

Selon un exemple de mise en œuvre de l'invention, au cours de l'étape c) la mise en place d'au moins un dispositif de soutien sur le plateau de chargement est effectuée manuellement.According to an exemplary implementation of the invention, during step c) the positioning of at least one support device on the loading platform is carried out manually.

Selon un autre exemple de mise en œuvre de l'invention, au cours de l'étape f) le chargement du véhicule routier sur le plateau de chargement est effectué soit par le haut au moyen d'une grue, d'un portique ou de tout autre moyen de levage, soit en faisant rouler le véhicule routier par ses roues sur le plateau de chargement, ce qui permet d'adapter l'invention à de nombreux types de chargement d'un véhicule routier sur un wagon ferroviaire.According to another example of implementation of the invention, during step f) the loading of the road vehicle on the loading platform is carried out either from above by means of a crane, a gantry or any other means of lifting, or by rolling the road vehicle by its wheels on the loading platform, which makes it possible to adapt the invention to many types of loading of a road vehicle on a railway wagon.

Le dispositif de soutien de la roue permet d'obtenir une retenue longitudinale et transversale du chargement par rapport à la poche ferroviaire. Cette retenue permet dans le cas d'une poche de chargement dissociée de la structure du wagon de sécuriser la position du chargement par rapport à la poche pendant les opérations de levage de l'ensemble poche / chargement et ainsi de travailler en sécurité.The wheel support device makes it possible to obtain longitudinal and transverse restraint of the load relative to the rail pocket. This retention makes it possible, in the case of a load pocket separated from the structure of the wagon, to secure the position of the load relative to the pocket during the lifting operations of the pocket/load assembly and thus to work in safety.

Cette retenue permet en outre de participer au maintien en position longitudinale du chargement par rapport au wagon dans les phases de tamponnement.This restraint also makes it possible to participate in maintaining the longitudinal position of the load relative to the wagon during the impact phases.

Mode(s) de réalisation de l'inventionEmbodiment(s) of the Invention

Les éléments structurellement et fonctionnellement identiques présents sur plusieurs figures distinctes, sont affectés d'une même référence numérique ou alphanumérique.The structurally and functionally identical elements present in several separate figures are assigned the same numerical or alphanumeric reference.

L'invention est préférentiellement prévue pour le ferroutage de semi-remorques sur des wagons ferroviaires. Elle peut s'appliquer cependant à tout type de wagon ferroviaire prévu pour le transport de véhicules routiers ou de tout autre charge comportant des roues ou des moyens similaires. Ainsi, dans ce descriptif, par véhicule routier équipé de roues, on entend également toute autre charge comportant des éléments de roulement cylindriques. Sur les figures, le véhicule routier est représenté à titre d'exemple sous la forme d'une semi-remorque comportant un ou trois essieux.The invention is preferably intended for the piggybacking of semi-trailers on railway wagons. However, it can apply to any type of railway wagon provided for the transport of road vehicles or any other load comprising wheels or similar means. Thus, in this description, road vehicle equipped with wheels also means any other load comprising cylindrical rolling elements. In the figures, the road vehicle is represented by way of example in the form of a semi-trailer comprising one or three axles.

L'invention se rapporte à un wagon ferroviaire (1) comportant un plateau de chargement (2) destiné à transporter un véhicule routier (3) équipé de roues (4).The invention relates to a railway wagon (1) comprising a loading platform (2) intended to transport a road vehicle (3) equipped with wheels (4).

Le plateau de chargement (2) peut être une poche portée par un wagon (1) de ferroutage de type wagon-poche, ou être le plancher d'un wagon (1) plat.The loading platform (2) can be a pocket carried by a piggyback car (1) of the car-pocket type, or be the floor of a flat car (1).

Ce wagon ferroviaire (1) comprend un système de réglage (5) du positionnement en hauteur des roues d'un véhicule routier prévu pour régler la hauteur des roues (4) du véhicule routier (3) à une hauteur prédéterminée par rapport au plateau de chargement (2) avant chaque transport et pendant toute la durée de celui-ci de sorte que le véhicule routier (3) transporté et le plateau de chargement (2) chargé se trouvent à un niveau bas supérieur ou égal de la limite basse (h) du gabarit ferroviaire.This railway wagon (1) comprises a system (5) for adjusting the height of the wheels of a road vehicle provided for adjusting the height of the wheels (4) of the road vehicle (3) to a predetermined height with respect to the loading (2) before each transport and for the entire duration thereof so that the road vehicle (3) transported and the loading platform (2) loaded are at a lower level greater than or equal to the lower limit (h ) of the railway gauge.

La limite basse (h) et la limite haute (h') du gabarit ferroviaire sont représentées sur les figures par des traits discontinus.The lower limit (h) and the upper limit (h') of the railway gauge are represented in the figures by broken lines.

Le système de réglage (5) comprend au moins un évidement (6) aménagé dans le plateau de chargement (2) au niveau de l'emplacement prévu pour les roues (4) du véhicule routier (3), chaque évidement (6) étant dimensionné pour permettre l'engagement au moins partiel des roues (4) du véhicule routier (3) à travers l'évidement (6).The adjustment system (5) comprises at least one recess (6) arranged in the loading platform (2) at the level of the location provided for the wheels (4) of the road vehicle (3), each recess (6) being sized to allow at least partial engagement of the wheels (4) of the road vehicle (3) through the recess (6).

Un tel évidement (6) permet une grande amplitude de réglage pour la position en hauteur du véhicule routier (3) en fonction de son poids et de l'usure des bogies (7) car elle permet de faire descendre les roues (4) dudit véhicule routier (3) sous le niveau de la face supérieure (8) du plateau de chargement (2).Such a recess (6) allows a wide range of adjustment for the height position of the road vehicle (3) according to its weight and the wear of the bogies (7) because it allows the wheels (4) of said road vehicle (3) below the level of the upper face (8) of the platform of loading (2).

Des évidements (6) sont préférentiellement prévus de chaque côté du plateau de chargement (2), pour les roues (4) des deux côtés du véhicule routier (3). Au sein d'un même axe longitudinal, ces évidements (6) peuvent être sous la forme d'un seul évidement (6) ou de plusieurs évidements (6) régulièrement répartis ou non sur la face supérieure (8) du plateau de chargement (2).Recesses (6) are preferably provided on each side of the loading platform (2), for the wheels (4) on both sides of the road vehicle (3). Within the same longitudinal axis, these recesses (6) can be in the form of a single recess (6) or several recesses (6) evenly distributed or not on the upper face (8) of the loading platform ( 2).

Le système de réglage (5) comprend également au moins un dispositif de soutien (9) pour les roues (4) d'un véhicule routier (3), ce dispositif de soutien (9) étant prévu sur le plateau de chargement (2) au niveau de l'emplacement prévu pour les roues (4) du véhicule routier (3). Chaque dispositif de soutien (9) comporte au moins une pièce de soutien (10) mobile et/ou déformable destinée à supporter au moins une roue (4) du véhicule routier (3) par au moins une zone de contact (11) de sorte que ladite roue (4) soit portée par l'au moins une zone de contact (11) et repose uniquement sur l'au moins une pièce de soutien (10), et non pas sur le plateau de chargement (2), le déplacement ou la déformation de l'au moins une pièce de soutien (10) déplaçant verticalement la position de l'au moins une zone de contact (11).The adjustment system (5) also comprises at least one support device (9) for the wheels (4) of a road vehicle (3), this support device (9) being provided on the loading platform (2) at the location provided for the wheels (4) of the road vehicle (3). Each support device (9) comprises at least one mobile and/or deformable support part (10) intended to support at least one wheel (4) of the road vehicle (3) by at least one contact zone (11) so that said wheel (4) is carried by the at least one contact zone (11) and rests only on the at least one support piece (10), and not on the loading platform (2), the displacement or the deformation of the at least one support part (10) vertically displacing the position of the at least one contact zone (11).

Un dispositif de soutien (9) est préférentiellement prévu pour chacune des roues (4) du véhicule routier (3).A support device (9) is preferably provided for each of the wheels (4) of the road vehicle (3).

Ainsi, le réglage en hauteur des roues (4) du véhicule routier (3) vers le bas par rapport au plateau de chargement (2) se fait par le réglage de la position ou de la conformation des pièces de soutien (10) et par l'enfoncement des roues (4) du véhicule routier (3) dans l'évidement (6) dudit plateau de chargement (2), les roues (4) étant portées et reposant uniquement sur les pièces de soutien (10) et non pas sur le plateau de chargement (2).Thus, the height adjustment of the wheels (4) of the road vehicle (3) downwards relative to the loading platform (2) is done by adjusting the position or the conformation of the support parts (10) and by the sinking of the wheels (4) of the road vehicle (3) into the recess (6) of said loading platform (2), the wheels (4) being carried and resting only on the support parts (10) and not on the loading platform (2).

Chaque pièce de soutien (10) est préférentiellement amovible et adaptée pour être mise en place manuellement sur le plateau de chargement (2).Each support piece (10) is preferably removable and adapted to be placed manually on the loading platform (2).

Selon une première variante de l'invention représentée sur les figures 1 à 22, chaque pièce de soutien (10) est sous la forme d'une cale (12) et le dispositif de soutien (9) comprend ainsi une paire de cales (12) en vis-à-vis prévues pour recevoir une des roues (4) du véhicule routier (3) en appui entre lesdites cales (12).According to a first variant of the invention represented on the figures 1 to 22 , each support piece (10) is in the form of a chock (12) and the support device (9) thus comprises a pair of facing chocks (12) provided to receive one of the wheels (4 ) of the road vehicle (3) resting between said wedges (12).

Selon l'écartement des cales (12), la roue (4) portée entre ces cales est positionnée plus ou moins haut. Plus les cales (12) sont écartées, plus la roue (4) est positionnée basse et pénètre profondément dans l'évidement (6) du plateau de chargement (2). A l'inverse, plus les cales (12) sont rapprochées, plus la roue (4) est positionnée haute et est remontée par rapport au plateau de chargement (2).Depending on the spacing of the wedges (12), the wheel (4) carried between these wedges is positioned more or less high. The more the wedges (12) are spaced apart, the lower the wheel (4) is positioned and penetrates deeply into the recess (6) of the plate loading (2). Conversely, the closer the wedges (12) are, the higher the wheel (4) is positioned and is raised relative to the loading platform (2).

Selon cette première variante, au sein de chaque paire de cales (12), l'au moins une zone de contact (11) est composée par une surface d'appui et de calage (13) oblique sur chaque cale (12), ces surfaces d'appui et de calage (13) obliques étant en regard l'une de l'autre.According to this first variant, within each pair of shims (12), the at least one contact zone (11) is composed of a support and wedging surface (13) oblique to each shim (12), these oblique bearing and wedging surfaces (13) facing each other.

Chaque cale (12) présente préférentiellement une surface d'appui et de calage (13) pour les roues (4), cette surface (13) étant inclinée par rapport à l'horizontal d'un angle compris entre 20° et 90°, préférentiellement compris entre 35° et 60°, et plus préférentiellement sensiblement égal à 45°.Each chock (12) preferably has a support and wedging surface (13) for the wheels (4), this surface (13) being inclined with respect to the horizontal by an angle of between 20° and 90°, preferably between 35° and 60°, and more preferably substantially equal to 45°.

La surface d'appui et de calage (13) de chaque cale (12) est préférentiellement une surface plane, présentant ou non des reliefs antidérapants.The support and wedging surface (13) of each wedge (12) is preferably a flat surface, with or without non-slip reliefs.

Au moins une des cales (12) est déplaçable manuellement en écartement relatif longitudinal au sein de chaque paire de cales (12), l'autre cale (12) pouvant être déplaçable manuellement ou fixe par rapport au plateau de chargement (2). Dans le cas préféré, les deux cales (12) sont déplaçables.At least one of the wedges (12) can be moved manually in relative longitudinal spacing within each pair of wedges (12), the other wedge (12) possibly being movable manually or fixed relative to the loading platform (2). In the preferred case, the two wedges (12) are movable.

Afin d'être immobilisée sur le plateau de chargement (2) chaque cale (12) déplaçable comporte au moins un dispositif d'immobilisation (14) et le plateau de chargement (2) comprend au moins un dispositif d'immobilisation complémentaire (15) destiné à coopérer avec le dispositif d'immobilisation (14) des cales (12) déplaçables pour immobiliser lesdites cales (12) sur le plateau de chargement (2).In order to be immobilized on the loading platform (2), each movable chock (12) comprises at least one immobilizing device (14) and the loading platform (2) comprises at least one additional immobilizing device (15) intended to cooperate with the immobilization device (14) of the movable wedges (12) to immobilize the said wedges (12) on the loading platform (2).

Selon une autre alternative de réalisation non représentée de l'invention, chaque cale (12) comprend une partie cylindrique, présentant ou non des reliefs antidérapants, prévue pour servir de surface d'appui et de calage oblique pour les roues (4).According to another alternative embodiment of the invention, not shown, each chock (12) comprises a cylindrical part, which may or may not have non-slip reliefs, intended to serve as a support surface and as oblique wedging for the wheels (4).

Selon une alternative de réalisation préférée de l'invention représentée sur les figures 11 à 22, chaque cale (12) est sous la forme d'un bloc massif présentant une surface d'appui et de calage (13) oblique pour les roues (4).According to a preferred alternative embodiment of the invention represented on the figures 11 to 22 , each chock (12) is in the form of a solid block having an oblique bearing and wedging surface (13) for the wheels (4).

On notera que les cales (12) utilisée dans cette invention diffèrent par leur forme, leur rôle et leur utilisation des cales amovibles habituellement utilisées dans les véhicules porte-voitures pour le calage des roues des véhicules chargés sur lesdits véhicules porte-voitures.It will be noted that the chocks (12) used in this invention differ in their shape, their role and their use from the removable chocks usually used in car carrier vehicles for chocking the wheels of vehicles loaded on said car carrier vehicles.

En effet, ces cales, largement connues, sont immobilisées selon des positions choisies sur le plateau de chargement du véhicule porte-voitures de sorte que les roues des véhicules routiers transportés sur le véhicule porte-voitures soient au moins partiellement immobilisées par leur appui sur ces cales. Ce système d'immobilisation des roues d'un véhicule routier par des cales est souvent utilisé d'un seul côté des roues et combiné avec d'autres dispositifs d'immobilisation, par exemple de type sangle, pour immobiliser totalement les roues du véhicule routier afin de sécuriser ce dernier sur le véhicule porte-voitures. Ainsi, ces cales ne sont généralement pas utilisées par paire. En outre, ces cales ne sont en aucune manière prévues pour régler la hauteur des véhicules transportés sur le véhicule porte-voitures et elles ne sont jamais utilisées pour cette fonction dans le cadre du transport d'un véhicule routier sur un wagon ferroviaire.Indeed, these wedges, widely known, are immobilized according to positions chosen on the loading platform of the car carrier vehicle so that the wheels of the road vehicles transported on the car carrier vehicle are at least partially immobilized by their support on these wedges. This system for immobilizing the wheels of a road vehicle by chocks is often used on one side of the wheels only and combined with other immobilizing devices, for example of the strap type, to completely immobilize the wheels of the road vehicle in order to secure the latter on the car transport vehicle. Thus, these wedges are generally not used in pairs. In addition, these wedges are in no way intended to adjust the height of the vehicles transported on the car transport vehicle and they are never used for this function in the context of the transport of a road vehicle on a railway wagon.

Selon une seconde variante de l'invention représentée sur les figures 23 à 30, chaque pièce de soutien (10) est sous la forme d'une pièce souple ou articulée (16) et le dispositif de soutien (9) comprend ainsi une pièce souple ou articulée (16) prévue pour porter une roue (4) et dont la conformation, c'est-à-dire selon que la pièce souple ou articulée (16) est lâche ou plus ou moins tendue, permet de modifier la hauteur de la roue (4) portée.According to a second variant of the invention represented on the figures 23 to 30 , each support piece (10) is in the form of a flexible or articulated piece (16) and the support device (9) thus comprises a flexible or articulated piece (16) intended to carry a wheel (4) and whose the conformation, that is to say depending on whether the flexible or articulated part (16) is loose or more or less taut, makes it possible to modify the height of the wheel (4) carried.

La pièce souple ou articulée (16) est apte à se déformer pour épouser la forme de l'au moins une roue (4) du véhicule routier (3) qu'elle soutient.The flexible or articulated part (16) is capable of deforming to match the shape of at least one wheel (4) of the road vehicle (3) that it supports.

Le dispositif de soutien (9) comprend également deux guides (17) prévus à l'avant et à l'arrière de l'au moins une roue (4), la pièce souple ou articulée (16) étant maintenue entre ces deux guides (17).The support device (9) also comprises two guides (17) provided at the front and at the rear of the at least one wheel (4), the flexible or articulated part (16) being held between these two guides ( 17).

Ces deux guides (17) sont prévus de part et d'autre de chaque évidement (6).These two guides (17) are provided on either side of each recess (6).

Il comprend aussi un dispositif de tension (18) prévu pour régler la tension de la pièce souple ou articulée (16) entre les deux guides (17).It also includes a tensioning device (18) designed to adjust the tension of the flexible or articulated piece (16) between the two guides (17).

Selon la tension de la pièce souple ou articulée (16), la roue (4) portée par celle-ci est positionnée plus ou moins haut. Plus la pièce souple ou articulée (16) est tendue, plus la forme de la zone de contact (11) se rapproche d'une droite horizontale, et plus la roue (4) est remontée par rapport au plateau de chargement (2). A l'inverse, moins la pièce souple ou articulée (16) est tendue, plus la courbure vers le bas de la zone de contact (11) augmente, et plus la roue (4) est positionnée basse et pénètre profondément dans l'évidement (6) du plateau de chargement (2).Depending on the tension of the flexible or articulated part (16), the wheel (4) carried by the latter is positioned more or less high. The more the flexible or articulated part (16) is stretched, the closer the shape of the contact zone (11) is to a horizontal straight line, and the more the wheel (4) is raised relative to the loading plate (2). Conversely, the less the flexible or articulated part (16) is stretched, the more the downward curvature of the contact zone (11) increases, and the lower the wheel (4) is positioned and penetrates deeply into the recess. (6) of the loading platform (2).

La pièce souple ou articulée (16) est préférentiellement sous la forme d'une corde, d'une sangle (19), d'un câble, d'une chaîne (20), de plaques articulées ou d'une combinaison de ces moyens. Il peut s'agir de tout moyen suffisamment souple pour se conformer aux roues (4) et suffisamment résistant pour supporter le poids du véhicule routier (3) transporté.The flexible or articulated piece (16) is preferably in the form of a rope, a strap (19), a cable, a chain (20), articulated plates or a combination of these means . It can be any way flexible enough to conform to the wheels (4) and strong enough to support the weight of the transported road vehicle (3).

Sur les figures 25 à 28, la pièce souple ou articulée (16) est sous la forme d'une chaîne (20), tandis que sur les figures 29 et 30, la pièce souple ou articulée (16) est sous la forme d'une sangle (19),On the figures 25 to 28 , the flexible or articulated piece (16) is in the form of a chain (20), while on the figures 29 and 30 , the flexible or articulated part (16) is in the form of a strap (19),

Selon une alternative de réalisation préférée de l'invention représentée sur les figures 25 à 30, le dispositif de tension (18) est constitué par deux guides (17) autour desquels la pièce souple ou articulée (16) est fixée et/ou enroulée.According to a preferred alternative embodiment of the invention represented on the figures 25 to 30 , the tensioning device (18) consists of two guides (17) around which the flexible or articulated part (16) is fixed and/or wound.

Le réglage en tension de la pièce souple ou articulée (16), permettant le réglage en hauteur des roues (4), peut par exemple se faire par enroulement ou déroulement de la pièce souple ou articulée (16) autour d'au moins des deux guides (17). Ainsi, lorsque la pièce souple ou articulée (16) est enroulée autour d'au moins des deux guides (17) en faisant tourner, sa tension augmente et la roue (4) remonte (voir figures 26 et 28), tandis que lorsque la pièce souple ou articulée (16) est déroulée autour d'au moins des deux guides (17) en faisant tourner celui-ci dans l'autre sens, sa tension diminue et la roue (4) descend (voir figures 25 et 27).The tension adjustment of the flexible or articulated part (16), allowing the height adjustment of the wheels (4), can for example be done by winding or unwinding the flexible or articulated part (16) around at least the two guides (17). Thus, when the flexible or articulated piece (16) is wound around at least two guides (17) while rotating, its tension increases and the wheel (4) rises (see figure 26 and 28 ), while when the flexible or articulated part (16) is unwound around at least two guides (17) by rotating the latter in the other direction, its tension decreases and the wheel (4) descends (see figure 25 and 27 ).

Les deux guides (17) sont alors préférentiellement cylindriques, leur rotation dans un sens ou dans l'autre assurant le réglage en hauteur des roues (4) du véhicule routier (3).The two guides (17) are then preferably cylindrical, their rotation in one direction or the other ensuring the height adjustment of the wheels (4) of the road vehicle (3).

Le dispositif de tension (18) peut comprendre un dispositif à cliquet (21) pour tendre la pièce souple ou articulée (16) et maintenir cette tension dans le temps de manière libérable et réglable. Le dispositif à cliquet (21) peut comprendre un levier (22) pour son actionnement manuel.The tensioning device (18) may comprise a ratchet device (21) for tensioning the flexible or articulated piece (16) and maintaining this tension over time in a releasable and adjustable manner. The ratchet device (21) may include a lever (22) for its manual actuation.

Afin de faciliter le processus de réglage en hauteur des roues (4) du véhicule routier (3), un premier dispositif de tension (18) peut être dédié à l'usure des bogies (7) du wagon ferroviaire (1) et l'autre à la charge.In order to facilitate the process of adjusting the height of the wheels (4) of the road vehicle (3), a first tensioning device (18) can be dedicated to the wear of the bogies (7) of the railway wagon (1) and the other in charge.

Par exemple, l'usure des bogies (7) du wagon ferroviaire (1) peut être indexée par paliers, par exemple au nombre de cinq, et le premier dispositif de tension (18) dédié à l'usure des bogies (7) comporte alors des positions indexées correspondantes, dont le nombre est par exemple identique à celui des paliers d'usure.For example, the wear of the bogies (7) of the railway wagon (1) can be indexed in stages, for example five in number, and the first tensioning device (18) dedicated to the wear of the bogies (7) comprises then corresponding indexed positions, the number of which is for example identical to that of the wear bearings.

De même, le niveau de charge du plateau de chargement (2) peut aussi être indexé par paliers, par exemple au nombre de trois, correspondant respectivement à un niveau de charge vide, à un niveau de mi-charge et à un niveau de charge. Le second dispositif de tension (18) dédié à la charge comporte alors des positions indexées correspondantes, dont le nombre est par exemple identique à celui des paliers de charge.Similarly, the load level of the loading plate (2) can also be indexed in stages, for example three in number, corresponding respectively to an empty load level, to a half-load level and to a load level. . The second voltage device (18) dedicated to the load comprises then corresponding indexed positions, the number of which is for example identical to that of the load stages.

Cette configuration rend aisé la reconnaissance à l'aptitude au transport via un contrôle de la rotation indexée de chaque guide (17) du dispositif de tension (18), cette rotation pouvant être indexée par des repères sur chaque guide (17) apparaissant dans une fenêtre de lecture ou en face d'un sélecteur, par l'inclinaison indexées du levier (22), ou par tout autre indication mécanique.This configuration makes it easy to recognize the suitability for transport via a control of the indexed rotation of each guide (17) of the tensioning device (18), this rotation being able to be indexed by marks on each guide (17) appearing in a reading window or in front of a selector, by the indexed inclination of the lever (22), or by any other mechanical indication.

Selon une autre alternative de réalisation préférée de l'invention, le dispositif de tension (18) est constitué par deux guides (17) dont l'un au moins est déplaçable manuellement en écartement relatif longitudinal au sein de chaque paire de guides (17), l'autre guide (17) pouvant être déplaçable manuellement ou fixe par rapport au plateau de chargement (2).According to another alternative preferred embodiment of the invention, the tensioning device (18) consists of two guides (17), at least one of which is manually movable in longitudinal relative spacing within each pair of guides (17). , the other guide (17) being movable manually or fixed relative to the loading plate (2).

Le réglage en tension de la pièce souple ou articulée (16), permettant le réglage en hauteur des roues (4), peut par exemple se faire par éloignement ou rapprochement relatif des deux guides (17), par le déplacement longitudinal d'un ou des deux guides (17). Ainsi, lorsque les deux guides (17) sont éloignés l'un de l'autre, la tension de la pièce souple ou articulée (16) augmente et la roue (4) remonte (voir figure 30), tandis que lorsque les deux guides (17) sont rapprochés l'un de l'autre, la tension de la pièce souple ou articulée (16) diminue et la roue (4) descend (voir figure 29).The tension adjustment of the flexible or articulated part (16), allowing the height adjustment of the wheels (4), can for example be done by moving away or relative approximation of the two guides (17), by the longitudinal displacement of one or of the two guides (17). Thus, when the two guides (17) are far from each other, the tension of the flexible or articulated part (16) increases and the wheel (4) rises (see figure 30 ), while when the two guides (17) are brought closer to each other, the tension of the flexible or articulated part (16) decreases and the wheel (4) descends (see figure 29 ).

Comme précédemment, afin de faciliter le processus de réglage en hauteur des roues (4) du véhicule routier (3), un premier guide (17) peut être dédié à l'usure des bogies (7) du wagon ferroviaire (1) et l'autre à la charge. Ainsi, la position longitudinale du guide (17) dédié à l'usure des bogies (7) peut être indexée sur le plateau de chargement (2) selon des paliers correspondants à différents niveaux d'usure des bogies (7), tandis que la position longitudinale du guide (17) dédié à la charge peut être indexée sur le plateau de chargement (2) selon des paliers correspondants à différents niveaux de charge plateau de chargement (2).As before, in order to facilitate the process of adjusting the height of the wheels (4) of the road vehicle (3), a first guide (17) can be dedicated to the wear of the bogies (7) of the railway wagon (1) and the other to charge. Thus, the longitudinal position of the guide (17) dedicated to the wear of the bogies (7) can be indexed on the loading platform (2) according to bearings corresponding to different levels of wear of the bogies (7), while the longitudinal position of the guide (17) dedicated to the load can be indexed on the loading plate (2) according to levels corresponding to different load levels loading plate (2).

Il est évident pour l'homme du métier d'adapter ce dernier système d'indexage de la position des guides (17) à un système d'indexage de la position des cales (12). Ainsi, la position longitudinale d'une première cale (12) dédiée à l'usure des bogies (7) peut être indexée sur le plateau de chargement (2) selon des paliers correspondants à différents niveaux d'usure des bogies (7), tandis que la position longitudinale d'une seconde cale (12) dédiée à la charge peut être indexée sur le plateau de chargement (2) selon des paliers correspondants à différents niveaux de charge plateau de chargement (2). Cet indexage peut par exemple être matérialisé au moyen de repères, chiffrés ou non, prévus sur le plateau de chargement (2) et venant en regard d'une fenêtre de lecture ou d'un sélecteur, ou être matérialisé au moyen de tout autre indication mécaniqueIt is obvious for those skilled in the art to adapt this latter system for indexing the position of the guides (17) to a system for indexing the position of the wedges (12). Thus, the longitudinal position of a first wedge (12) dedicated to the wear of the bogies (7) can be indexed on the loading platform (2) according to bearings corresponding to different levels of wear of the bogies (7), while the longitudinal position of a second wedge (12) dedicated to the load can be indexed on the loading platform (2) according to levels corresponding to different loading platform (2) load levels. This indexing can for example be materialized by means of marks, encrypted or not, provided on the loading platform (2) and facing a reading window or a selector, or be materialized by means of any other mechanical indication

Comme pour les cales (12), chaque guide (17) déplaçable peut comporter au moins un dispositif d'immobilisation (14) tandis que le plateau de chargement (2) comprend au moins un dispositif d'immobilisation complémentaire (15) destiné à coopérer avec le dispositif d'immobilisation (14) des guides (17) déplaçables pour immobiliser lesdits guides (17) sur le plateau de chargement (2).As for the wedges (12), each movable guide (17) can comprise at least one immobilization device (14) while the loading plate (2) comprises at least one complementary immobilization device (15) intended to cooperate with the device (14) for immobilizing the guides (17) which can be moved to immobilize the said guides (17) on the loading platform (2).

Chaque cale (12) ou guide (17) peut être monté(e) de manière amovible sur le plateau de chargement (2). Ce montage peut être indexé en position.Each wedge (12) or guide (17) can be removably mounted on the loading platform (2). This assembly can be indexed in position.

De manière générale, chaque cale (12) ou chaque guide (17) déplaçable peut comprendre l'un des dispositifs d'immobilisation (14) suivants :

  • au moins un élément d'engagement mâle ou femelle (23) prévu pour s'engager avec un élément d'engagement mâle ou femelle complémentaire (23) parmi une pluralité d'éléments d'engagement mâles ou femelles complémentaires (24) régulièrement réparties dans la face supérieure (8) du plateau de chargement (2) ou dans des rails longitudinaux (25) solidaires de la face supérieure (8) du plateau de chargement (2) ;

  • une paire de vis de serrage (30) prévues pour s'engager à immobilisation dans un orifice fileté (31) parmi des orifices filetés (31) régulièrement répartis dans la face supérieure (8) du plateau de chargement (2) ou dans des rails longitudinaux (25) solidaires de la face supérieure (8) du plateau de chargement (2) ;
  • une paire de boulons de serrage (32) prévus pour s'engager à immobilisation dans un orifice (29) ou un oblong (33) parmi des orifices (29) ou des oblongs (33) régulièrement répartis dans la face supérieure (8) du plateau de chargement (2) ou dans des rails longitudinaux (25) solidaires de la face supérieure (8) du plateau de chargement (2).
In general, each wedge (12) or each movable guide (17) may comprise one of the following immobilization devices (14):
  • at least one male or female engagement element (23) designed to engage with a complementary male or female engagement element (23) among a plurality of complementary male or female engagement elements (24) regularly distributed in the upper face (8) of the loading platform (2) or in longitudinal rails (25) integral with the upper face (8) of the loading platform (2);
  • a pair of hooks (26) designed to engage immobilization in a longitudinal slot (27) among slots (27) regularly distributed in the upper face (8) of the loading platform (2);
  • a pair of movable engagement fingers (28) designed to engage in the locking position in orifices (29) among a plurality of orifices (29) regularly distributed in the upper face (8) of the loading platform (2 ) or in longitudinal rails (25) secured to the upper face (8) of the loading platform (2);

De manière plus concrète, il est possible de prévoir plusieurs modes de réalisation pour les dispositifs d'immobilisation (14) et les dispositifs d'immobilisation complémentaires (15) destinés à coopérer.More concretely, it is possible to provide several embodiments for the immobilization devices (14) and the complementary immobilization devices (15) intended to cooperate.

Des dispositifs d'immobilisation (14) et dispositifs d'immobilisation complémentaires (15) sont donnés à titre d'exemple sur les figures 11 à 22 pour des cales (12), mais il est évident pour l'homme du métier de les adapter sans effort pour des guides (17).Immobilizers (14) and complementary immobilizers (15) are given by way of example on the figures 11 to 22 for wedges (12), but it is obvious for those skilled in the art to adapt them effortlessly for guides (17).

Selon une première alternative de réalisation représentée sur la figure 11, les éléments d'engagement mâles ou femelles (14) de la cale (12) ou du guide (17) sont sous la forme d'une réglette (34) transversale en relief, continue ou non, se prolongeant transversalement vers le bas depuis la face du dessous (35) de chaque cale (12) ou de chaque guide (17), logée en immobilisation et calage dans une gorge (36) transversale réceptrice parmi une pluralité de gorges (36) transversales réceptrices régulièrement réparties dans la face supérieure (8) du plateau de chargement (2) ou dans des rails longitudinaux (25) solidaires de la face supérieure (8) du plateau de chargement (2), le profil de chaque gorge (36) étant complémentaire de celui de la réglette (34).According to a first alternative embodiment shown in the figure 11 , the male or female engagement elements (14) of the shim (12) or of the guide (17) are in the form of a transverse strip (34) in relief, continuous or not, extending transversely downwards from the underside (35) of each wedge (12) or of each guide (17), housed in immobilization and wedging in a transverse receiving groove (36) among a plurality of transverse receiving grooves (36) regularly distributed in the upper face (8) of the loading platform (2) or in longitudinal rails (25) integral with the upper face (8) of the loading platform (2), the profile of each groove (36) being complementary to that of the strip ( 34).

Chaque doigt d'engagement (28) peut être poussé vers l'extérieur en position de verrouillage par un ressort (39), tandis qu'une butée de préhension (40) permet de le reculer manuellement en position de déverrouillage.According to a fourth alternative embodiment represented on the figures 15 and 16 , the immobilizing device (14) of a chock (12) comprises a pair of engagement fingers (28) movable between a locking position and an unlocking position, arranged transversely and extending projecting laterally from the two lateral faces (37) of each wedge (12), the free end of each engagement finger (28) being oriented transversely outwards and provided to engage in the locking position in orifices (29) among a plurality of orifices (29) regularly distributed longitudinally in the faces (38) facing two longitudinal rails (25) integral with the upper face (8) of the loading platform (2).

Selon l'alternative de réalisation représentée sur les figures 17 et 18, le dispositif d'immobilisation complémentaire (15) est sous la forme d'une pluralité d'oblongs (33) régulièrement répartis longitudinalement dans la face supérieure (8) du plateau de chargement (2) et les boulons de serrage (32) se prolongent verticalement.According to the alternative embodiment represented on the figures 17 and 18 , the complementary immobilization device (15) is in the form of a plurality of oblongs (33) regularly distributed longitudinally in the upper face (8) of the loading platform (2) and the tightening bolts (32) extend vertically.

Selon l'alternative de réalisation représentée sur les figures 19 à 22, le dispositif d'immobilisation complémentaire (15) est sous la forme d'une pluralité d'oblongs (33) régulièrement répartis longitudinalement dans les faces (38) en regard de deux rails longitudinaux (25) solidaires de la face supérieure (8) du plateau de chargement (2) et les boulons de serrage (32) se prolongent horizontalement.According to the alternative embodiment represented on the figures 19 to 22 , the complementary immobilizing device (15) is in the form of a plurality of oblongs (33) regularly distributed longitudinally in the faces (38) facing two longitudinal rails (25) integral with the upper face (8) of the loading platform (2) and the clamping bolts (32) extend horizontally.

Selon une sixième alternative de réalisation non représentée sur les figures, le dispositif d'immobilisation (14) d'une cale (12) comprend une paire de vis de serrage (30) disposées transversalement et se prolongeant horizontalement à travers une paire d'ouvertures traversantes prévues dans chaque cale (12), lesdites vis de serrage (30) étant prévues pour s'engager à immobilisation dans un orifice fileté (31) parmi une pluralité d'orifices filetés (31) régulièrement répartis longitudinalement dans les faces (38) en regard de deux rails longitudinaux (25) solidaires de la face supérieure (8) du plateau de chargement (2).According to a sixth alternative embodiment not shown in the figures, the device (14) for immobilizing a wedge (12) comprises a pair of clamping screws (30) arranged transversely and extending horizontally through a pair of openings through-holes provided in each wedge (12), said clamping screws (30) being provided to engage with immobilization in a threaded orifice (31) among a plurality of threaded orifices (31) regularly distributed longitudinally in the faces (38) facing two longitudinal rails (25) integral with the upper face (8) of the loading platform (2).

Selon une alternative de réalisation du dispositif d'immobilisation (14) représentée sur les figures 15 à 22, chaque cale (12) présente une extension latérale (42) comportant un dispositif d'immobilisation (14). Ceci permet notamment de déporter les parties de la cale (12) comportant des ouvertures traversantes afin de faciliter la manipulation des vis (30), des boulons (32), des écrous (41) et des butées de préhension (40). Sur ces figures, les extensions latérales (42) coulissent chacune contre le flanc vertical (43) d'un des rails longitudinaux (25).According to an alternative embodiment of the immobilizer (14) represented on the figures 15 to 22 , each chock (12) has a lateral extension (42) comprising an immobilizing device (14). This makes it possible in particular to offset the parts of the wedge (12) comprising through openings in order to facilitate the manipulation of the screws (30), the bolts (32), the nuts (41) and the gripping stops (40). In these figures, the lateral extensions (42) each slide against the vertical side (43) of one of the longitudinal rails (25).

Selon les alternatives de réalisation représentées sur les figures 19 20, les rails longitudinaux (25) peuvent également présenter une extension latérale (44) prévue pour supporter au moins les extrémités latérales des cales (12), par exemple au niveau de leurs extensions latérales (42).Depending on the alternative embodiments represented on the figures 19 20 , the longitudinal rails (25) may also have a lateral extension (44) provided to support at least the lateral ends of the wedges (12), for example at their lateral extensions (42).

On notera que les différents moyens du dispositif d'immobilisation complémentaire (15) pour les cales (12) et les guides (17) qui sont prévu sur le plateau de chargement (2) peuvent être prévus soit directement sur le plateau de chargement (2), soit sur une pièce qui est rapportée et solidarisée sur le plateau de chargement (2).It will be noted that the various means of the complementary immobilization device (15) for the wedges (12) and the guides (17) which are provided on the loading platform (2) can be provided either directly on the loading platform (2 ), or on a part which is attached and secured to the loading platform (2).

Selon une troisième variante de l'invention représentée sur les figures 31 à 38, chaque pièce de soutien (10) est sous la forme d'un réceptacle rigide (47) prévu pour être introduit dans un évidement (6) du plateau de chargement (2) et pour supporter une roue (4) du véhicule routier (3) à une hauteur prédéterminée par rapport au plateau de chargement (2).According to a third variant of the invention represented on the figures 31 to 38 , each support piece (10) is in the form of a rigid receptacle (47) intended to be introduced into a recess (6) of the loading platform (2) and to support a wheel (4) of the road vehicle (3 ) at a predetermined height relative to the loading platform (2).

Selon cette troisième variante de l'invention, le réceptacle rigide (47) présente une partie médiane (48) en creux se prolongeant vers le bas, qui est prévue pour pénétrer vers le bas à travers l'évidement (6) du plateau de chargement (2). La partie médiane (48) est préférentiellement sensiblement horizontale et sa face supérieure est prévue pour supporter la roue (4) du véhicule routier (3).According to this third variant of the invention, the rigid receptacle (47) has a hollow central part (48) extending downwards, which is provided to penetrate downwards through the recess (6) of the loading plate (2). The middle part (48) is preferably substantially horizontal and its upper face is provided to support the wheel (4) of the road vehicle (3).

Le réceptacle rigide (47) présente également des rebords périphériques (49) prévus pour venir en appui sur au moins un dispositif de positionnement en hauteur (50) du réceptacle rigide (47). Ces rebords périphériques (49) se prolongent horizontalement en dehors de l'évidement (6) du plateau de chargement (2) et au-dessus du plateau de chargement (2).The rigid receptacle (47) also has peripheral edges (49) designed to bear against at least one height positioning device (50) of the rigid receptacle (47). These peripheral flanges (49) extend horizontally outside the recess (6) of the loading platform (2) and above the loading platform (2).

Un dispositif de positionnement en hauteur (50) du réceptacle rigide (47) est préférentiellement prévu sur le plateau de chargement (2) à la fois à l'avant et à l'arrière de la roue (4) du véhicule routier (3), chacun de ces dispositifs de positionnement en hauteur (50) du réceptacle rigide (47) étant prévu pour supporter chacun un rebord périphérique (49) du réceptacle rigide (47).A height positioning device (50) of the receptacle rigid (47) is preferably provided on the loading platform (2) both at the front and at the rear of the wheel (4) of the road vehicle (3), each of these height positioning devices (50 ) of the rigid receptacle (47) being provided to each support a peripheral rim (49) of the rigid receptacle (47).

Chaque dispositif de positionnement en hauteur (50) du réceptacle rigide (47) peut par exemple comporter une cale à degré (51), une came rotative (53), une cale biaise ou tout autre dispositif permettant de modifier la hauteur à laquelle le réceptacle rigide (47) est supporté.Each height positioning device (50) of the rigid receptacle (47) may for example comprise a wedge (51), a rotating cam (53), an angled wedge or any other device making it possible to modify the height at which the receptacle rigid (47) is supported.

Sur les figures 31 et 32 données à titre d'exemple, chaque dispositif de positionnement en hauteur (50) du réceptacle rigide (47) comporte une cale à degré (51). En réglant l'écartement mutuel de chacune de ces cales à degré (51), les rebords périphériques (49) du réceptacle rigide (47) viennent reposer sur une marche plus ou moins haute de chaque cale à degré (51) et il est ainsi possible de régler la hauteur à laquelle le réceptacle rigide (47) est positionné.On the figures 31 and 32 given by way of example, each device for positioning the height (50) of the rigid receptacle (47) comprises a wedge (51). By adjusting the mutual spacing of each of these step wedges (51), the peripheral edges (49) of the rigid receptacle (47) come to rest on a more or less high step of each step wedge (51) and it is thus possible to adjust the height at which the rigid receptacle (47) is positioned.

Les cales du dispositif de positionnement en hauteur (50) du réceptacle rigide (47) peuvent comporter n'importe quel dispositif d'immobilisation similaire à ceux des cales (12) de la première variante de l'invention, tandis que le plateau de chargement (2) peut comprendre un dispositif d'immobilisation complémentaire destiné à coopérer avec le dispositif d'immobilisation des cales pour les immobiliser sur le plateau de chargement (2).The wedges of the height positioning device (50) of the rigid receptacle (47) can comprise any immobilization device similar to those of the wedges (12) of the first variant of the invention, while the loading platform (2) may comprise an additional immobilizing device intended to cooperate with the device for immobilizing the chocks in order to immobilize them on the loading platform (2).

Sur les figures 33 et 34 données à titre d'exemple, chaque dispositif de positionnement en hauteur (50) du réceptacle rigide (47) comporte une came rotative (53) monté à pivotement sur un support (54) porté ou fixé sur plateau de chargement (2). En faisant pivoter la came rotative (53), les rebords périphériques (49) du réceptacle rigide (47) sont plus ou moins soulevés et il est ainsi possible de régler la hauteur à laquelle le réceptacle rigide (47) est positionné.On the figures 33 and 34 given by way of example, each height positioning device (50) of the rigid receptacle (47) comprises a rotary cam (53) pivotally mounted on a support (54) carried or fixed on the loading platform (2). By pivoting the rotary cam (53), the peripheral edges (49) of the rigid receptacle (47) are more or less raised and it is thus possible to adjust the height at which the rigid receptacle (47) is positioned.

Chaque cale ou came du dispositif de positionnement en hauteur (50) du réceptacle rigide (47) peut être montée fixe ou de manière amovible sur le plateau de chargement (2). Ce montage peut être indexé en position.Each wedge or cam of the height positioning device (50) of the rigid receptacle (47) can be fixed or removably mounted on the loading platform (2). This assembly can be indexed in position.

Selon la troisième variante de l'invention, un même système de réglage (5) peut également comporter deux dispositifs de positionnement en hauteur (50) différents.According to the third variant of the invention, the same adjustment system (5) can also comprise two different height positioning devices (50).

Selon les alternatives de réalisation représentées sur les figures 35 à 38, un même système de réglage (5) peut par exemple comporter un premier dispositif de positionnement en hauteur (50) comportant une cale à degré (51) (voir figures 35 à 36) ou une came rotative (53) (voir figures 37 à 38), et un second dispositif de positionnement en hauteur (50) comportant une articulation (55) par laquelle le réceptacle rigide (47) est monté pivotant sur le plateau de chargement (2).Depending on the alternative embodiments represented on the figures 35 to 38 , the same adjustment system (5) can for example comprise a first height positioning device (50) comprising a step wedge (51) (see figures 35 to 36 ) or a rotary cam (53) (see figures 37 to 38 ), and a second height positioning device (50) comprising an articulation (55) by which the rigid receptacle (47) is pivotally mounted on the loading platform (2).

L'articulation (55) peut être montée fixe ou de manière amovible sur le plateau de chargement (2). Ce montage peut être indexé en position.The articulation (55) can be fixed or removably mounted on the loading platform (2). This assembly can be indexed in position.

Selon la troisième variante de l'invention, le système de réglage (5) peut également comporter des dispositifs de suspension (52), par exemple sous la forme de ressorts, qui sont prévus entre le plateau de chargement (2) et les rebords périphériques (49) du réceptacle rigide (47). Par leur délestage du poids du réceptacle rigide (47), ces dispositifs de suspension (52), permettent de faciliter la manutention du dispositif de soutien (9) lors des opérations de réglage en hauteur de la roue (4) du véhicule routier (3).According to the third variant of the invention, the adjustment system (5) can also comprise suspension devices (52), for example in the form of springs, which are provided between the loading platform (2) and the peripheral edges (49) of the rigid receptacle (47). By relieving the weight of the rigid receptacle (47), these suspension devices (52) make it possible to facilitate the handling of the support device (9) during height adjustment operations of the wheel (4) of the road vehicle (3 ).

Sur les figures 1 à 38, le dispositif de soutien (9) est monté directement sur le plateau de chargement (2).On the figures 1 to 38 , the support device (9) is mounted directly on the loading platform (2).

Selon une variante de l'invention représentée de manière schématique sur les figures 39 à 42, le dispositif de soutien (9) peut être monté soit sur le plateau de chargement (2) par l'intermédiaire d'une plaque mobile (56). Cette plaque mobile (56), prévue entre le dispositif de soutien (9) et le plateau de chargement (2), est montée réglable en position longitudinale sur le plateau de chargement (2).According to a variant of the invention represented schematically on the figures 39 to 42 , the support device (9) can be mounted either on the loading platform (2) via a movable plate (56). This movable plate (56), provided between the support device (9) and the loading platform (2), is mounted adjustable in the longitudinal position on the loading platform (2).

Sur les figures 39 à 42, les pièces de soutien (10) pour les roues (4) sont représentées schématiquement par des parallélépipèdes, car cette variante de l'invention peut s'adapter à tous les types de pièce de soutien (10) précédemment décrites ou envisageables. Il est à noter que selon cette variante, la plaque mobile (56) se substitue à la surface du plateau de chargement (2) sur lequel est monté le dispositif de soutien (9) de l'invention. Ainsi, selon cette variante les dispositifs d'immobilisation complémentaire et les rails longitudinaux qui, selon les autres variantes, sont prévus sur le plateau de chargement (2), sont alors prévus sur la plaque mobile (56). Les modes de réalisation précédents peuvent ainsi être adaptés à cette variante en remplaçant la face supérieure (8) du plateau de chargement (2) par la face supérieure (57) de la plaque mobile (56).On the figures 39 to 42 , the support parts (10) for the wheels (4) are represented schematically by parallelepipeds, because this variant of the invention can be adapted to all types of support part (10) previously described or possible. It should be noted that according to this variant, the movable plate (56) replaces the surface of the loading platform (2) on which the support device (9) of the invention is mounted. Thus, according to this variant, the additional immobilization devices and the longitudinal rails which, according to the other variants, are provided on the loading platform (2), are then provided on the movable plate (56). The previous embodiments can thus be adapted to this variant by replacing the upper face (8) of the loading platform (2) with the upper face (57) of the movable plate (56).

Selon cette variante, lorsque les roues (4) d'un véhicule routier (3) sont réglées en hauteur grâce au système de réglage (5) de l'invention, il est possible de déplacer ledit véhicule routier (3) longitudinalement par rapport au plateau de chargement (2) sans avoir à bouger le véhicule routier (3) par rapport aux dispositifs de soutien (9) qui supporte ses roues (4). Cela permet par exemple de déplacer longitudinalement une semi-remorque portée sur plateau de chargement (2) et dont la hauteur est réglée au moyen d'un dispositif de soutien (9) selon l'invention, sans avoir à dérégler le positionnement en hauteur de la semi-remorque, mais en faisant simplement coulisser longitudinalement les plaques mobiles (56) sur le plateau de chargement (2). Il est ainsi possible, à titre d'exemple, de déplacer longitudinalement une semi-remorque portée sur le plateau de chargement (2) pour positionner le pivot d'attelage de ladite semi-remorque au niveau d'un dispositif d'immobilisation de pivot d'attelage prévu sur le plateau de chargement (2).According to this variant, when the wheels (4) of a road vehicle (3) are adjusted in height thanks to the adjustment system (5) of the invention, it is possible to move said road vehicle (3) longitudinally with respect to the loading platform (2) without having to move the road vehicle (3) relative to the support devices (9) which support its wheels (4). This makes it possible, for example, to move a semi-trailer mounted on a flatbed longitudinally. load (2) and whose height is adjusted by means of a support device (9) according to the invention, without having to disturb the height positioning of the semi-trailer, but simply by sliding the movable plates ( 56) on the loading platform (2). It is thus possible, by way of example, to move a semi-trailer carried longitudinally on the loading platform (2) to position the coupling pin of said semi-trailer at the level of a pin immobilizer coupling provided on the loading platform (2).

La plaque mobile (56) présente un évidement (58) prévu pour pouvoir être superposé au-dessus d'un évidement (6) aménagé dans le plateau de chargement (2) au niveau de l'emplacement prévu pour les roues (4) du véhicule routier (3). L'évidement (58) de la plaque mobile (56) peut avoir des dimensions similaires à celles de l'évidement (6) aménagé dans le plateau de chargement (2), ou présenter des dimensions différentes, du moment que celles-ci permettent l'engagement au moins partiel d'une roue (4) à travers l'évidement (58).The movable plate (56) has a recess (58) intended to be able to be superposed above a recess (6) provided in the loading platform (2) at the level of the location provided for the wheels (4) of the road vehicle (3). The recess (58) of the movable plate (56) may have dimensions similar to those of the recess (6) arranged in the loading platform (2), or have different dimensions, as long as these allow the at least partial engagement of a wheel (4) through the recess (58).

Selon un mode de réalisation donné à titre d'exemple sur les figures 39 à 42, la plaque mobile (56) est sous la forme d'une pièce de support (59) rigide et plate qui est montée coulissante sur le plateau de chargement (2), par exemple par engagement de ses bords latéraux dans un logement prévu dans des rails longitudinaux (60) prévus sur le plateau de chargement (2).According to an embodiment given by way of example on the figures 39 to 42 , the movable plate (56) is in the form of a rigid and flat support piece (59) which is slidably mounted on the loading platform (2), for example by engagement of its lateral edges in a housing provided in longitudinal rails (60) provided on the loading platform (2).

Selon cette variante, le dispositif de soutien (9) peut comporter un dispositif de verrouillage permettant de bloquer la plaque mobile (56) en position par rapport au plateau de chargement (2). Sur les figures 41 et 42, le verrouillage de la plaque mobile (56) par rapport au plateau de chargement (2) est ainsi réalisé au moyen d'un goujon transversal (62) de verrouillage venant s'engager de manière libérable dans une des indentations (61) prévues dans les bords latéraux de la plaque mobile (56).Il est évident pour l'homme du métier d'envisager d'autres moyens permettant de déplacer la plaque mobile (56) par rapport au plateau de chargement (2) et de verrouiller la plaque mobile (56) en position par rapport à celui-ci, aussi d'autres exemples ne seront pas donnés ici.According to this variant, the support device (9) may comprise a locking device making it possible to lock the movable plate (56) in position relative to the loading platform (2). On the figures 41 and 42 , the locking of the movable plate (56) with respect to the loading platform (2) is thus achieved by means of a transverse locking pin (62) which engages in a releasable manner in one of the indentations (61) provided in the side edges of the movable plate (56).It is obvious for the person skilled in the art to envisage other means making it possible to move the movable plate (56) relative to the loading plate (2) and to lock the plate mobile (56) in position relative to the latter, so other examples will not be given here.

L'invention se rapporte également à un procédé de réglage du positionnement en hauteur d'un véhicule routier (3) équipé de roues (4) sur un plateau de chargement (2) porté ou solidaire d'un wagon ferroviaire (1) en vue du transport dudit véhicule (1) sur le wagon ferroviaire (1). Ce procédé comprend les étapes successives suivantes :

  1. a) détermination de la hauteur à laquelle le véhicule routier (3) doit être positionné pendant son transport sur le wagon ferroviaire (1), en fonction des variables liées au wagon (1) à vide et en charge, pour se trouver à un niveau bas proche de la limite inférieure du gabarit ferroviaire mais sans la dépasser ;
  2. b) détermination de la hauteur à laquelle les roues (4) du véhicule routier (3) doivent être positionnées pour obtenir la hauteur de véhicule déterminée à l'étape a) ;
  3. c) mise en place d'au moins un dispositif de soutien (9) sur le plateau de chargement (2) au niveau de l'emplacement prévu pour les roues (4) du véhicule routier (3) ;
  4. d) réglage de la position ou de la conformation d'au moins une pièce de soutien (10) pour que la hauteur de roue déterminée à l'étape b) soit obtenue lorsqu'une roue (4) du véhicule routier (3) repose sur cette pièce de soutien (10) ;
  5. e) immobilisation de l'au moins une pièce de soutien (10) sur le plateau de chargement (2) selon la position ou la conformation réglée à l'étape d) ;
  6. f) chargement du véhicule routier (3) sur le plateau de chargement (2) en plaçant une de ses roues (4) sur l'au moins une pièce de soutien (10) immobilisée à l'étape e).
The invention also relates to a method for adjusting the positioning in height of a road vehicle (3) equipped with wheels (4) on a loading platform (2) carried or secured to a railway wagon (1) in view transporting said vehicle (1) on the railway wagon (1). This process comprises the following successive steps:
  1. a) determination of the height at which the road vehicle (3) must be positioned during its transport on the railway wagon (1), depending on the variables linked to the empty and laden wagon (1), to be at a low level close to the lower limit of the railway gauge but without exceeding it;
  2. b) determining the height at which the wheels (4) of the road vehicle (3) must be positioned to obtain the vehicle height determined in step a);
  3. c) placing at least one support device (9) on the loading platform (2) at the location provided for the wheels (4) of the road vehicle (3);
  4. d) adjusting the position or the conformation of at least one support piece (10) so that the wheel height determined in step b) is obtained when a wheel (4) of the road vehicle (3) rests on this support piece (10);
  5. e) immobilization of the at least one support piece (10) on the loading plate (2) according to the position or the conformation set in step d);
  6. f) loading the road vehicle (3) on the loading platform (2) by placing one of its wheels (4) on the at least one support piece (10) immobilized in step e).

Au cours de l'étape c), la mise en place d'au moins un dispositif de soutien (9) sur le plateau de chargement (2) est préférentiellement effectuée manuellement.During step c), the positioning of at least one support device (9) on the loading platform (2) is preferably carried out manually.

Au cours de l'étape f) le chargement du véhicule routier (3) sur le plateau de chargement (2) est effectué soit par le haut au moyen d'une grue, d'un portique ou de tout autre moyen de levage, soit en faisant rouler le véhicule routier (3) par ses roues (4) sur le plateau de chargement (2).During step f) the loading of the road vehicle (3) on the loading platform (2) is carried out either from above by means of a crane, a gantry or any other lifting means, or by rolling the road vehicle (3) by its wheels (4) on the loading platform (2).

Afin de comprendre le principe de réglage en hauteur en hauteur d'un véhicule routier sur un plateau de chargement (2) au moyen du système de réglage (5) et selon le procédé de l'invention, on pourra se référer à divers exemples illustrés sur les figures 1 à 6.In order to understand the principle of height adjustment in height of a road vehicle on a loading platform (2) by means of the adjustment system (5) and according to the method of the invention, reference may be made to various illustrated examples. on the figures 1 to 6 .

Sur les figures 1 et 23, les bogies (7) du wagon ferroviaire (1) ne sont pas usés et le véhicule routier (3) est léger, aussi le plateau de chargement (2) n'est pas abaissé. Par léger, on entend ici que le véhicule routier (3) présente un poids négligeable par rapport au poids maximum que le plateau de chargement (2) peut supporter. Dans le cas d'une semi-remorque, il s'agit par exemple d'une semi-remorque vide ou transportant une charge très légère. Puisque le plateau de chargement (2) n'est pas abaissé, il se trouve au plus haut et le véhicule routier (3) doit être placé au plus bas possible afin de respecter le gabarit ferroviaire, c'est-à-dire la hauteur minimale (h) entre les rails et la partie la plus basse du plateau de chargement (2) et de son chargement, ainsi que la hauteur maximale (h') entre les rails et la partie la plus haute du plateau de chargement (2) et de son chargement. Pour placer le véhicule routier (3) le plus bas possible, chaque pièce de soutien (10) est réglée de sorte de laisser pénétrer la partie inférieure des roues (4) du véhicule routier (3) sous le niveau de la face supérieure (8) du plateau de chargement (2), tout en supportant les roues (4) du véhicule routier (3) et en les immobilisant longitudinalement.On the figure 1 and 23 , the bogies (7) of the railway wagon (1) are not worn and the road vehicle (3) is light, so the loading platform (2) is not lowered. By light, it is meant here that the road vehicle (3) has a negligible weight compared to the maximum weight that the loading platform (2) can support. In the case of a semi-trailer, it is for example an empty semi-trailer or one carrying a very light load. Since the board of load (2) is not lowered, it is at the highest point and the road vehicle (3) must be placed as low as possible in order to respect the railway gauge, i.e. the minimum height (h) between the rails and the lowest part of the loading platform (2) and its load, as well as the maximum height (h') between the rails and the highest part of the loading platform (2) and its load . To place the road vehicle (3) as low as possible, each support piece (10) is adjusted so as to allow the lower part of the wheels (4) of the road vehicle (3) to penetrate below the level of the upper face (8 ) of the loading platform (2), while supporting the wheels (4) of the road vehicle (3) and immobilizing them longitudinally.

Sur la figure 2, les bogies (7) du wagon ferroviaire (1) sont neufs et le véhicule routier (3) est lourd, aussi le plateau de chargement (2) est abaissé car le poids de la charge fait fléchir le plateau de chargement (2). Puisque le point le plus bas du plateau de chargement (2) est abaissé, le véhicule routier (3) doit être relevé par rapport à la situation précédente afin de respecter le gabarit ferroviaire. Grâce à la position ou la conformation de chaque pièce de soutien (10) le réglage en hauteur des roues peut être très précis pour ajuster la position du véhicule routier (3) vers le bas de la hauteur voulue.On the figure 2 , the bogies (7) of the railway wagon (1) are new and the road vehicle (3) is heavy, so the loading platform (2) is lowered because the weight of the load causes the loading platform (2) to deflect. Since the lowest point of the loading platform (2) is lowered, the road vehicle (3) must be raised relative to the previous situation in order to respect the rail gauge. Thanks to the position or the conformation of each support piece (10) the height adjustment of the wheels can be very precise in order to adjust the position of the road vehicle (3) downwards by the desired height.

Sur les figures 3 et 24, les bogies (7) du wagon ferroviaire (1) sont usés et le véhicule routier (3) est lourd, notamment dans le cas d'une semi-remorque transportant une charge très lourde. C'est le poids de la charge portée par le plateau de chargement (2) qui fait fléchir celui-ci, et le plateau de chargement (2) est encore abaissé car le diamètre des roues des bogies (7) est réduit par rapport à ceux d'un bogie (18) neuf. Ainsi, dans sa partie fléchie correspondant à son point le plus bas, le plateau de chargement (2) est très abaissé et se trouve à la limite basse admise. Là aussi le véhicule routier (3) doit être relevé par rapport à la situation précédente afin de respecter le gabarit ferroviaire. Le véhicule routier (3) est relevé de sorte que ses roues (4) reposent sensiblement à la même hauteur que si elles reposaient sur un plateau de chargement (2) classique dépourvu d'évidement (6). La position ou la conformation de chaque pièce de soutien (10) est alors réglée de sorte que les roues (4) du véhicule routier (3) se retrouvent au niveau de la face supérieure du plateau de chargement (2) tout en les immobilisant longitudinalement.On the figure 3 and 24 , the bogies (7) of the railway wagon (1) are worn and the road vehicle (3) is heavy, in particular in the case of a semi-trailer transporting a very heavy load. It is the weight of the load carried by the loading plate (2) which causes it to bend, and the loading plate (2) is further lowered because the diameter of the wheels of the bogies (7) is reduced compared to those of a new bogie (18). Thus, in its bent part corresponding to its lowest point, the loading plate (2) is very low and is at the lower limit allowed. Here too the road vehicle (3) must be raised relative to the previous situation in order to respect the rail gauge. The road vehicle (3) is raised so that its wheels (4) rest substantially at the same height as if they were resting on a conventional loading platform (2) with no recess (6). The position or conformation of each support piece (10) is then adjusted so that the wheels (4) of the road vehicle (3) are at the level of the upper face of the loading platform (2) while immobilizing them longitudinally .

Afin de comprendre le principe de réglage en hauteur d'un véhicule routier (3) sur un plateau de chargement (2) de type poche selon l'invention, on pourra se référer à divers exemples illustrés sur les figures 6 à 10. De manière générale, un plateau de chargement (2) de type poche est prévu pour être suspendu longitudinalement entre deux éléments d'extrémité (45) du wagon ferroviaire (1) qui comportent les bogies (7) ou être suspendu latéralement entre deux longerons (46) du wagon ferroviaire (1), comme cela est représenté à titre d'exemple sur la figure 9.In order to understand the principle of height adjustment of a road vehicle (3) on a loading platform (2) of the pocket type according to the invention, reference may be made to various examples illustrated on the figures 6 to 10 .
