Description

La présente invention concerne un procédé et un système pour prolonger une voie de chemin de fer en aval d'une extrémité de voie existante.The present invention relates to a method and system for extending a railroad track downstream of an existing track end.

Pour mettre en place les traverses et les rails nécessaires à la construction de voies de chemin de fer, les procédés et systèmes connus sont généralement lourds et volumineux.To set up sleepers and rails necessary for the construction of railroad tracks, known methods and systems are generally heavy and bulky.

Divers moyens ont déjà été proposés pour alléger les systèmes de pose de voie de chemin de fer.Various means have already been proposed for lightening the railroad laying systems.

Le document GB2432564 décrit une machine agencée pour déposer des panneaux de voie à côté d'un wagon transportant les panneaux de voie, au moyen d'un bras pivotant. La machine décrite convient pour créer une nouvelle voie à côté d'une voie préexistante. Il apparaît difficile, voire impossible d'utiliser la machine décrite pour créer une nouvelle voie en absence de voie préexistante parallèle à la nouvelle voie.The document GB2432564 describes a machine arranged to deposit track panels next to a wagon carrying the track panels, by means of a pivoting arm. The described machine is suitable for creating a new lane next to a pre-existing lane. It appears difficult or impossible to use the machine described to create a new path in the absence of pre-existing path parallel to the new path.

Le document WO2009/050439 utilise des moyens de petite dimension, notamment un ou plusieurs véhicules capables de se déplacer hors voie, qui ne nécessitent pas l'existence d'une voie adjacente préexistante. Cependant les moyens décrits qui ne permettent de déplacer que des rails, ne sont visiblement pas utilisables si des traverses ne sont pas préalablement posées.The document WO2009 / 050439 uses means of small size, including one or more vehicles capable of moving off-road, which do not require the existence of a pre-existing adjacent channel. However, the means described which only move rails, are obviously not usable if sleepers are not previously laid.

La présente invention a pour but de palier les inconvénients de l'état antérieur connu de la technique.The present invention aims to overcome the disadvantages of the prior art known in the art.

A cet effet, de façon à prolonger une voie de chemin de fer en aval d'une extrémité de voie existante, l'invention a pour objet un procédé comprenant :

  • une étape d'acheminement d'un panneau courant de voie, dans laquelle un opérateur fait rouler sur la voie existante, un lorry motorisé qui comporte des roues ferroviaires et un mécanisme de déplacement hors voie en position rétractée et qui supporte ledit panneau courant, de façon à approcher le lorry motorisé de ladite extrémité de la voie ;
  • une étape de positionnement du panneau courant en aval de la voie existante, dans laquelle l'opérateur déploie le mécanisme de déplacement hors voie de façon à positionner une extrémité amont du panneau courant en aplomb de l'extrémité de voie existante en faisant rouler le lorry motorisé en aval de la voie existante ;
  • une étape de libération du panneau courant, dans laquelle l'opérateur évacue le lorry motorisé en laissant l'extrémité amont du panneau courant en aplomb de l'extrémité de voie existante ; et
  • une étape de pose du panneau courant, dans laquelle l'opérateur abaisse le panneau courant jusqu'à faire coïncider l'extrémité amont du panneau courant avec l'extrémité de voie existante.
For this purpose, in order to extend a railroad track downstream from an existing track end, the subject of the invention is a method comprising:

  • a step of positioning the current panel downstream of the existing channel, in which the operator deploys the off-road movement mechanism so as to position an upstream end of the current board vertically in line with the existing track end by rolling the lorry motorized downstream of the existing track;
  • a step of releasing the current panel, wherein the operator evacuates the motorized lorry leaving the upstream end of the current board in line with the existing track end; and
  • a step of laying the current board, wherein the operator lowers the current board to match the upstream end of the current board with the existing track end.

  • l'étape de positionnement comprend une deuxième phase transitoire dans laquelle l'opérateur abaisse la voie de liaison dans le prolongement de la voie existante, une troisième phase transitoire dans laquelle l'opérateur fait progresser le lorry motorisé sur la voie de liaison jusqu'à pouvoir déployer le mécanisme de déplacement hors voie en dehors de la voie existante, et une quatrième phase transitoire dans laquelle l'opérateur déploie le mécanisme de déplacement hors voie.
Advantageously, to deploy the off-road displacement mechanism:
  • the routing step comprises a first transitional phase in which the operator approaches the motorized lorry by making it support a linkage linkage suspended in front, until a rear end of the connecting path is in a position existing lane end;
  • the positioning step comprises a second transitional phase in which the operator lowers the link path in the extension of the existing path, a third transient phase in which the operator advances the motorized lorry on the connecting path to ability to deploy the off-road move mechanism out of the existing track, and a fourth transient phase in which the operator deploys the off-track move mechanism.

Particulièrement, pour évacuer le lorry motorisé, l'étape de libération comprend une cinquième phase transitoire dans laquelle l'opérateur utilise le mécanisme de déplacement hors voie pour ramener le lorry motorisé au dessus de la voie de liaison, une sixième phase transitoire dans laquelle l'opérateur rétracte le mécanisme de déplacement hors voie pour remettre les roues ferroviaires du lorry motorisé en contact avec la voie de liaison, une septième phase transitoire dans laquelle l'opérateur fait refouler le lorry motorisé de la voie de liaison vers la voie existante de façon à saisir la voie de liaison, une huitième phase transitoire dans laquelle l'opérateur remonte la voie de liaison, et une neuvième phase transitoire dans laquelle l'opérateur recule le lorry motorisé en ramenant la voie de liaison au dessus de la voie existante.In particular, to evacuate the motorized lorry, the release step includes a fifth transitional phase in which the operator uses the off-road movement mechanism for returning the motorized lorry over the linkage path, a sixth transient phase in which the operator retracts the off-road movement mechanism to return the railway wheels of the motorized lorry into contact with the linkage path, a seventh transitional phase in which the operator pushes the motorized lorry from the link route to the existing pathway so as to seize the link path, an eighth transitional phase in which the operator goes up the link path, and a ninth transitional phase in which the operator backs the motorized lorry by bringing the linkage back to the top of the existing lane.

Particulièrement l'étape de pose comprend une quatrième phase de pose dans laquelle l'opérateur baisse ledit au moins un premier portique extensible de manutention de façon à poser le panneau courant dans le prolongement de la voie existante puis décroche ledit premier portique extensible de manutention du panneau courant, et une cinquième phase de pose dans laquelle l'opérateur relève ledit premier portique extensible de manutention.Particularly the laying step comprises a fourth laying phase in which the operator lowers said at least one first expandable handling gantry so as to lay the current board in the extension of the existing track and then picks up said first expandable gantry handling port. current panel, and a fifth phase of installation in which the operator raises said first expandable gantry handling.

Avantageusement encore, le procédé comprend une étape de transfert dans laquelle l'opérateur charge un panneau suivant sur le lorry motorisé de façon à reboucler l'exécution du procédé sur l'étape d'acheminement dans laquelle le panneau suivant devient le panneau courant.Advantageously, the method comprises a transfer step in which the operator loads a following panel on the motorized lorry so as to loop back the execution of the method on the routing step in which the next panel becomes the current panel.

Particulièrement, l'étape de transfert comprend une première phase de transfert dans laquelle l'opérateur amène une poutre supportée par le lorry motorisé sous au moins un deuxième portique extensible de manutention auquel est suspendu ledit panneau suivant, et une deuxième phase de transfert dans laquelle l'opérateur abaisse ledit deuxième portique extensible de manutention de façon à poser ledit panneau suivant sur ladite poutre.In particular, the transfer step comprises a first transfer phase in which the operator brings a beam supported by the motorized lorry under at least one second extensible handling gantry to which said next panel is suspended, and a second transfer phase in which the operator lowers said second expandable handling gantry so as to place said next panel on said beam.

Pour prolonger une voie de chemin de fer en aval d'une extrémité de voie existante, la figure 16 montre un procédé qui comprend notamment une étape 101 d'acheminement d'un panneau courant de voie, une étape 103 de positionnement du panneau courant en aval de la voie existante, dans laquelle un opérateur déploie un mécanisme de déplacement hors voie de façon à positionner une extrémité amont du panneau courant en aplomb de l'extrémité de voie existante, une étape 105 de libération du panneau courant, dans laquelle l'opérateur rétracte le mécanisme de déplacement hors voie, et une étape 107 de pose du panneau courant, dans laquelle l'opérateur abaisse le panneau courant jusqu'à faire coïncider l'extrémité amont du panneau courant avec l'extrémité avale de voie existante.To extend a railway line downstream from an existing lane end, the figure 16 shows a method which comprises in particular a step 101 for routing a channel running panel, a step 103 for positioning the current panel downstream of the existing channel, in which an operator deploys an off-road displacement mechanism so as to position an upstream end of the current board plumb with the existing track end, a step 105 of release of the current board, in which the operator retracts the off-road movement mechanism, and a step 107 of laying the current board, wherein the operator lowers the current panel to match the upstream end of the current panel with the downstream end of the existing channel.

Sur chacune des figures 1 à 12 qui précèdent, on a représenté sensiblement au centre une extrémité 36 de voie 31 de chemin de fer déjà existante sur la droite. On a représenté à gauche de l'extrémité de la voie existante, une plateforme 30 sur laquelle le procédé et le système expliqués ci-dessous, permettent de prolonger la voie de chemin de fer en aval de l'extrémité de la voie existante (vers la gauche sur la figure).On each of Figures 1 to 12 which precedes, there is shown substantially in the center an end 36 of the already existing railway track 31 on the right. We shown to the left of the end of the existing track, a platform 30 on which the method and system explained below, allow to extend the railroad track downstream of the end of the existing track (to the left in the figure).

Sur les figurés 13 à 15, l'extrémité 36 a été décalée sur la gauche de façon à mieux pouvoir expliquer certaines étapes qui ont lieu sur la voie existante en amont de l'extrémité 36.In FIGS. 13 to 15, the end 36 has been shifted to the left so as to better explain certain steps that take place on the existing path upstream of the end 36.

La figure 16 synthétise et complète les étapes du procédé expliquées à présent en référence aux figures 1 à 15.The figure 16 synthesizes and completes the process steps explained now with reference to Figures 1 to 15 .

Les figures 1 et 2 représentent respectivement une première phase de pose 1 et une première phase transitoire 2 au sein de l'étape 101 d'acheminement d'un panneau courant 32 de voie, dans laquelle un opérateur fait rouler sur la voie 31 existante, un lorry 34 motorisé qui supporte le panneau courant 32 de façon à approcher le lorry 34 motorisé de l'extrémité 36 de la voie.The Figures 1 and 2 represent respectively a first laying phase 1 and a first transient phase 2 within step 101 of routing a current track panel 32, in which an operator rolls on the existing track 31, a motorized lorry 34 which supports the current panel 32 so as to approach the motorized lorry 34 of the end 36 of the track.

A titre purement illustratif et non limitatif, l'opérateur est un être humain, une équipe d'êtres humains ou un automate programmable. Lorsque l'opérateur est un être humain, un poste portable de télécommande permet de commander les fonctions qui sont chacune asservie pour mettre en oeuvre le procédé. L'utilisation d'un automate programmable est possible à condition de l'équiper des capteurs et du programme suffisants à prévoir l'ensembles des situations qui peuvent se produire. Un être humain peut faire face à des situations inattendues et variées tout en contrôlant le bon déroulement du procédé sans avoir à investir dans une quantité de capteurs et une complexité combinatoire de programmation prohibitives.As a purely illustrative and non-limiting example, the operator is a human being, a team of human beings or a programmable automaton. When the operator is a human being, a portable remote control unit can control the functions that are each slave to implement the method. The use of a PLC is possible provided that the sensors and the program are sufficient to predict the set of situations that may occur. A human being can cope with unexpected and varied situations while controlling the smooth running of the process without having to invest in a lot of sensors and a combinatorial complexity of prohibitive programming.

On a représenté en figure 21 un système qui permet de mettre en oeuvre le procédé conforme à l'invention, de façon à prolonger la voie de chemin de fer en aval de l'extrémité 36 de voie 31 existante. Le système comprend notamment un lorry 34 motorisé, une poutre 44 agencée pour supporter le panneau courant 32 sur le lorry 34 motorisé, au moins un portique extensible de manutention 33 agencé pour y accrocher le panneau courant 32, et une voie de liaison 38 suspendue en potence à l'avant du lorry 34 motorisé de manière détachable.We have shown in figure 21 a system which makes it possible to implement the method according to the invention, so as to extend the railway track downstream from the end 36 of existing track 31. The system comprises in particular a motorized lorry 34, a beam 44 arranged to support the current panel 32 on the motorized lorry 34, at least one expandable handling gantry 33 arranged to hang the current panel 32, and a connecting channel 38 suspended in stem in the front of lorry 34 motorized detachably.

Dans un mode de réalisation préférée représentée sur les figures 17 à 20, le lorry 34 motorisé comporte des roues ferroviaires 51 pour rouler sur la voie 31 existante, et un mécanisme 50 de déplacement hors voie rétractable. Le mécanisme 50 est par exemple un mécanisme à chenilles que des bras 52 permettent de descendre en dessous du niveau des roues ferroviaires 51. D'autres mécanismes de déplacement hors voie peuvent être envisagés comme par exemple un mécanisme à roues équipées de pneus tout-terrain. Ainsi, en position rétractée comme représentée sur les figures 17 et 18, le mécanisme 50 de déplacement hors voie est relevé pour mettre les roues ferroviaires 51 en contact avec des rails 53. En position déployée comme représentée sur les figures 19 et 20, le mécanisme 50 de déplacement hors voie est abaissé pour prendre appui sur la plate-forme 30 de manière à soulever le lorry 34 motorisé jusqu'à désolidariser les roues ferroviaires 51 des rails 53. La motorisation du lorry 34 est par exemple de nature hydraulique, télécommandable.In a preferred embodiment shown in Figures 17 to 20 , the motorized lorry 34 comprises rail wheels 51 for rolling on the existing track 31, and a retractable off-road movement mechanism 50. The mechanism 50 is for example a crawler mechanism that arms 52 allow to descend below the level of the railway wheels 51. Other off-road displacement mechanisms can be envisaged such as a wheel mechanism equipped with off-road tires. . Thus, in the retracted position as shown on the Figures 17 and 18 , the off-road displacement mechanism 50 is raised to put the railway wheels 51 in contact with the rails 53. In the deployed position as shown in FIGS. Figures 19 and 20 , the off-road displacement mechanism 50 is lowered to rest on the platform 30 so as to lift the motorized lorry 34 until the rail wheels 51 are detached from the rails 53. The motorization of the lorry 34 is for example of a hydraulic nature , remote controlled.

La poutre 44 a pour but de maintenir le panneau 32 à plat. En absence de poutre, le panneau dont la longueur est par exemple de 36 mètres ou plus, voire seulement de 24 mètres ou moins, a tendance à fléchir sous son propre poids auquel s'ajoute le poids des portiques 33 lorsqu'il n'est pas posé sur le sol à cause de la souplesse des rails sur une telle longueur. La longueur de la poutre est de préférence adaptée à la longueur du panneau 32. Une longueur légèrement plus courte permet d'alléger le système sans provoquer de flèche observable en extrémité.The beam 44 is intended to keep the panel 32 flat. In the absence of a beam, the panel whose length is for example 36 meters or more, or even only 24 meters or less, tends to bend under its own weight plus the weight of the gantries 33 when it is not not placed on the ground because of the flexibility of the rails on such a length. The length of the beam is preferably adapted to the length of the panel 32. A slightly shorter length makes it possible to lighten the system without causing an end observable arrow.

La quantité de portiques extensibles de manutention 33, est elle aussi fonction de la longueur du panneau 32. Dans l'exemple illustré par la figure 21, trois portiques extensibles de manutention 33 conviennent lorsque la longueur du panneau 32 est égale à 36 mètres.The amount of expandable handling gantries 33 is also a function of the length of the panel 32. In the example illustrated by FIG. figure 21 , three expandable handling gantries 33 are suitable when the length of the panel 32 is equal to 36 meters.

La figure 25a et la figure 25b montrent, respectivement en vue de face et en perspective, une réalisation possible de portique extensible de manutention posé sur des rails 41. Le portique extensible de manutention 33 ici représenté, est équipé de roues 40 qui lui permettent de rouler sur les rails 41. Le portique extensible de manutention 33 comprend un palonnier télescopique 45 horizontal qui comporte un bras 46 extensibles de part et d'autre. Un fourreau 49 vertical est fixé à chaque extrémité de bras 46 extensible. Une jambe 39 en forme de colonne verticale est montée coulissante dans chaque fourreau 49. Sur la figure 24, les bras 46 sont représentés en position rétractées. Une centrale hydraulique 48 est pilotable à distance pour étendre les deux bras 46 extensibles de façon à déployer les deux fourreaux 49 de part et d'autre du lorry 34 motorisé sur chacun de ses flancs puis pour faire descendre chacune des jambes 39 jusqu'à en mettre le pied en appui sur le sol.The figure 25a and the figure 25b show, respectively in front view and in perspective, a possible embodiment of expandable gantry handling placed on rails 41. The expandable handling gantry 33 shown here, is equipped with wheels 40 which allow it to roll on the rails 41. The Expandable handling gantry 33 comprises a horizontal telescopic beam 45 which has an arm 46 extendable on either side. A vertical sleeve 49 is attached to each extensible arm end 46. A leg 39 in the form of a vertical column is slidably mounted in each sleeve 49. figure 24 the arms 46 are shown in the retracted position. A hydraulic unit 48 is remotely controllable to extend the two extensible arms 46 so as to deploy the two sleeves 49 on either side of the motorized lorry 34 on each of its flanks and then to lower each of the legs 39 to put the foot on the ground.

Des pinces 47 radiocommandées permettent d'accrocher le panneau courant 32 sous le portique extensible de manutention 33 de sorte que lorsque les deux jambes 39, appuyant sur le sol, hissent le portique extensible de manutention 33, le panneau 32 est soulevé de la poutre 44. Les pinces représentées ouvertes sur les figures 25a et 25b, sont représentées dans leur position fermée sur les figures 26a et 26b.Radio controlled clamps 47 allow the current panel 32 to be hooked under the expandable handling frame 33 so that when the two legs 39, pressing on the ground, hoist the expandable handling frame 33, the panel 32 is lifted from the beam 44. The pliers shown open on the Figures 25a and 25b , are represented in their closed position on the Figures 26a and 26b .

Lorsque plusieurs portiques extensibles de manutention 33 sont utilisés, ils sont reliés par des barres de liaison 54 de façon à constituer une structure rigide. Les centrales hydrauliques 48 sont alors synchronisées de façon à générer un mouvement uniforme de déploiement puis de montée et de descente des portiques extensibles de manutention 33.When several expandable handling gantries 33 are used, they are connected by connecting bars 54 so as to constitute a rigid structure. The hydraulic power stations 48 are then synchronized so as to generate a uniform movement of deployment and then raising and lowering the expandable gantry cranes 33.

Comme expliqué ci-dessus, la poutre 44 est essentiellement utile lorsque le panneau 32 est long. Un panneau très court pourrait très bien être supporté directement sur le lorry 34 motorisé. Un panneau de longueur moyenne pourrait être supporté sur une poutre portée par le seul lorry 34 motorisé. Lorsque le panneau 32 est de taille conséquente comme représenté sur la figure 21, le système comprend un lorry ferroviaire 35 pour supporter la poutre 44 en accompagnant le lorry 34 motorisé dans ses déplacements, sans quitter la voie.As explained above, the beam 44 is essentially useful when the panel 32 is long. A very short panel could very well be supported directly on the motorized lorry 34. A panel of medium length could be supported on a beam carried by the only lorry 34 motorized. When the panel 32 is of consistent size as shown on the figure 21 , the system comprises a rail lorry 35 for supporting the beam 44 by accompanying the motorized lorry 34 in its movements, without leaving the track.

Comme représenté sur la figure 24, la voie de liaison 38 comprend deux rails de longueur sensiblement égale à celle du lorry 34 motorisé, maintenus par des traverses 57 de longueur égale à celle de l'écartement des rails. En d'autres termes, les traverses ne dépassent pas sur les côtés des rails extérieurs à la voie de liaison 38. Cette disposition permet d'éviter tous contacts du mécanisme 50 de déplacement hors voie avec les têtes de traverses du dernier panneau posé ou de la voie existante avant prolongement. Dans l'exemple de réalisation illustré par la figure 21, la voie de liaison 38 est suspendue à l'extrémité avant de la poutre 44. En absence de poutre, d'autres montages pourraient être envisagés, par exemple au moyen d'une potence spécifique montée sur le lorry 34 motorisé.As shown on the figure 24 the connecting track 38 comprises two rails of a length substantially equal to that of the motorized lorry 34, held by sleepers 57 of equal length to that of the spacing of the rails. In other words, the cross members do not protrude on the sides of the rails outside the connecting track 38. This arrangement makes it possible to avoid any contacts of the off-road movement mechanism 50 with the crossheads of the last panel placed on the track. the existing lane before extension. In the exemplary embodiment illustrated by the figure 21 the linkage 38 is suspended at the front end of the beam 44. In the absence of a beam, other arrangements could be envisaged, for example by means of a specific bracket mounted on the motorized lorry 34.

Le montage de la voie de liaison 38 en extrémité de la poutre 44 est détaillé sur la figure 22. La partie avant de la poutre 44 comprend une poutrelle 55 ajourée soutenue par un treillis 56 pour concilier légèreté et rigidité horizontale. La partie inférieure d'un crochet 58 agrippe la voie de liaison 38. Une extrémité supérieure de barre 61 pivote autour d'un axe 63 solidaire de la poutrelle 55. Le crochet 58 pivote autour d'un axe 64 en extrémité basse de la barre 61.The mounting of the connecting channel 38 at the end of the beam 44 is detailed on the figure 22 . The front portion of the beam 44 comprises a perforated beam 55 supported by a mesh 56 to reconcile lightness and horizontal rigidity. The lower part of a hook 58 grips the connecting track 38. An upper end of bar 61 pivots about an axis 63 secured to the beam 55. The hook 58 pivots about an axis 64 at the bottom end of the bar 61.

Dans la position relevée de la voie de liaison 38 qui est représentée en vue de côté sur la figure 23b et en vue de face sur la figure 23a, un vérin 60 fixé à la poutrelle 55, tire en position rentrée sur un câble 59 dont l'extrémité opposée est fixée au sommet du crochet 58. Deux joues 62 permettent de maintenir la voie de liaison 38 en position relevée dans l'alignement de la voie 31.In the raised position of the connecting path 38 which is shown in side view on the figure 23b and in front view on the figure 23a a jack 60 fixed to the beam 55 pulls in the retracted position on a cable 59 whose opposite end is fixed to the top of the hook 58. Two cheeks 62 make it possible to maintain the connecting channel 38 in the raised position in the alignment of the way 31.

Dans la position abaissée de la voie de liaison 38 qui est représentée en vue de côté sur la figure 22b et en vue de face sur la figure 22a, le vérin 60 en position sortie, relâche la traction sur le câble 59 de sorte que la voie de liaison 38 quitte les deux joues 62 pour se mettre dans l'alignement de la voie 31.In the lowered position of the connecting track 38 which is shown in side view on the figure 22b and in front view on the figure 22a , the jack 60 in the extended position, releases the traction on the cable 59 so that the linking path 38 leaves the two cheeks 62 to align with the channel 31.

Le crochet 64 est de forme connue pour permettre d'accrocher fermement la voie de liaison en position relevée et pour se désolidariser aisément de la voie de liaison en position abaissée lorsque la poutre 44 avance alors que la voie de liaison 38 repose sur le sol.The hook 64 is of known shape to allow to firmly attach the linkage in the raised position and to easily separate the connection path in the lowered position when the beam 44 advance while the connecting path 38 rests on the ground.

Dans la phase de pose 1 représentée en figure 1 et dans la phase transitoire 2 représentée en figure 2, le mécanisme 50 de déplacement hors voie est en position rétractée de façon à approcher le lorry motorisé de l'extrémité de la voie existante en le faisant rouler sur la voie 31.In the laying phase 1 represented in figure 1 and in the transitional phase 2 represented in figure 2 , the off-road displacement mechanism 50 is in the retracted position so as to approach the motorized lorry of the end of the existing track by rolling it on the track 31.

Dans la phase de pose 1 de l'étape 101 d'acheminement, l'opérateur accroche au moins un portique extensible de manutention 33 sur le panneau courant 32 qui repose sur la poutre 44, notamment en télécommandant les pinces 47 de façon à les refermer fermement sur les rails du panneau courant 32. La poutre 44 chargée du panneau arrive sur le front de pose.In the laying phase 1 of the routing step 101, the operator hooks at least one expandable handling gantry 33 on the current panel 32 which rests on the beam 44, in particular by remotely controlling the clamps 47 so as to close them again. firmly on the rails of the current panel 32. The beam 44 loaded panel arrives on the laying front.

Dans la phase transitoire 2 de l'étape 101, l'opérateur approche le lorry 34 motorisé avec la voie de liaison 38 suspendue en position relevée à l'avant de la poutre 44, jusqu'à mettre l'extrémité arrière de la voie de liaison 38 en aplomb de l'extrémité 36 de voie 31 existante. La mise en aplomb de la voie de liaison valide alors une transition 102 vers l'étape 103 de positionnement du panneau courant 32 en aval de la voie 31 existante.In the transitional phase 2 of the step 101, the operator approaches the motorized lorry 34 with the linking track 38 suspended in the raised position at the front of the beam 44, until the rear end of the track link 38 in line with the end 36 of track 31 existing. Placing the link path then validates a transition 102 to the step 103 of the current panel 32 downstream of the existing path 31.

Les figures 3, 4 et 5 représentent respectivement trois phases transitoires 3, 4 et 5 au sein de l'étape 103. Dans l'étape 103, l'opérateur déploie le mécanisme de déplacement hors voie de façon à pouvoir faire rouler le lorry 34 motorisé en aval de la voie 31 existante pour positionner l'extrémité amont 37 de la voie de liaison 38 en aplomb de l'extrémité 36 de voie 31 existante.The Figures 3, 4 and 5 respectively represent three transitional phases 3, 4 and 5 in step 103. In step 103, the operator deploys the off-road displacement mechanism so as to be able to roll the motorized lorry 34 downstream of the track 31 existing to position the upstream end 37 of the connecting path 38 in line with the end of 31 existing channel 31.

Dans la phase transitoire 3 de l'étape 103 de positionnement, l'opérateur abaisse la voie de liaison 38 dans le prolongement de la voie 31 existante, notamment en télécommandant le vérin 60.In the transitional phase 3 of the positioning step 103, the operator lowers the link track 38 in the extension of the existing track 31, in particular by remotely controlling the jack 60.

Dans la phase transitoire 4 de l'étape 103, l'opérateur fait progresser le lorry 34 motorisé sur la voie de liaison 38 jusqu'à pouvoir déployer le mécanisme de déplacement hors voie en dehors de la voie 31 existante. Dans la phase transitoire 4 représentée sur la figure 4, l'absence de traverses qui se prolongent en dehors de la voie de liaison, permet de déployer le mécanisme de déplacement hors voie lorsque le mécanisme est intégralement sur la voie de liaison. Les chenilles ou les roues tout-terrain du mécanisme ne sont pas gênées par les traverses pour toucher le sol.In the transitional phase 4 of the step 103, the operator advances the motorized lorry 34 on the linkage path 38 until the off-road displacement mechanism can be deployed outside the existing lane 31. In the transitional phase 4 represented on the figure 4 the absence of crossmembers which extend outside the linkage channel makes it possible to deploy the off-road displacement mechanism when the mechanism is entirely on the linkage path. The tracks or the off-road wheels of the mechanism are not hindered by the sleepers to touch the ground.

Dans la phase transitoire 5 de l'étape 103, l'opérateur déploie le mécanisme de déplacement hors voie en télécommandant une rotation des bras 52 qui permettent un contact simultané du mécanisme 50 de déplacement hors voie avec le sol et des roues 51 de manière soulagée avec les rails de la voie de liaison en gardant le lorry 34 motorisé horizontal. L'opérateur désaccouple le moteur d'entraînement des roue ferroviaires et accouple le moteur d'entraînement au mécanisme 50 de déplacement hors voie.In the transitional phase of step 103, the operator deploys the off-road movement mechanism by controlling a rotation of the arms 52 which allow simultaneous contact of the off-road displacement mechanism 50 with the ground and the wheels 51 in a relieved manner. with the tracks of the connecting track keeping the lorry 34 motorized horizontal. The operator uncouples the drive motor of the railway wheels and couples the drive motor to the off-road movement mechanism 50.

Les figures 6 et 7 représentent respectivement deux phases de pose 6 et 7 au sein de l'étape 103 de positionnement.The Figures 6 and 7 respectively represent two laying phases 6 and 7 within the positioning step 103.

Dans la phase de pose 6, l'opérateur fait avancer le lorry 34 motorisé au moyen des chenilles qui appuient sur le sol de chaque côté des rails de la voie de liaison 38. Tant que les roues ferroviaires touchent les rails 41 de la voie de liaison, elles suivent simplement en roue libre comme celles du lorry ferroviaire 35. L'opérateur continue à faire avancer le lorry 34 qui quitte progressivement la voie de liaison sans subir de désalignement, ni latéral, ni vertical. Le lorry continue à progresser hors voie jusqu'à ce que, lorsque l'intégralité du panneau courant 32 est en aval de la voie 31 existante avec l'extrémité arrière du panneau 32 à l'aplomb de l'extrémité avale de la voie existante 31, l'opérateur immobilise le lorry 34 motorisé. La longueur en porte à faux du panneau 32 à l'arrière de la poutre 44 et la longueur en porte à faux de la poutre 44 à l'arrière du lorry ferroviaire 35 sont telles que le lorry ferroviaire 35 reste sur la voie de liaison 38 lorsque l'extrémité arrière du panneau 32 est à l'aplomb de l'extrémité avale de la voie existante 31.In the laying phase 6, the operator advances the motorized lorry 34 by means of the tracks which bear on the ground on each side of the rails of the connecting track 38. As long as the railway wheels touch the rails 41 of the track link, they simply follow freewheeling as those of rail lorry 35. The operator continues to advance the lorry 34 which gradually leaves the linkage without experiencing misalignment, lateral or vertical. The lorry continues to progress off track until, when the entire current panel 32 is downstream of the existing channel 31 with the rear end of the panel 32 vertically above the downstream end of the existing channel 31, the operator immobilizes the motorized lorry 34. The cantilevered length of the panel 32 at the rear of the beam 44 and the cantilevered length of the beam 44 at the rear of the rail lorry 35 are such that the rail lorry 35 remains on the linkage 38 when the rear end of the panel 32 is in line with the downstream end of the existing channel 31.

Dans la phase de pose 7, l'opérateur baisse de manière synchrone les jambes 39 des portiques extensibles de manutention 33 jusqu'à ce que les jambes 39 appuyant sur le sol, soulèvent le portique 33 dont les pinces 47 radiocommandées lèvent alors le panneau courant 32 au dessus de la poutre supportée par le lorry 34 motorisé en laissant l'extrémité amont ou arrière 37 du panneau courant 32 en aplomb de l'extrémité avale 36 de la voie 31 existante. La mise en aplomb du panneau 32 valide une transition 104 vers l'étape 105 de libération du panneau.In the laying phase 7, the operator synchronously lowers the legs 39 of the expandable handling gantry 33 until the legs 39 pressing on the ground lift the gantry 33 whose radio-controlled clamps 47 then raise the current panel 32 above the beam supported by the motorized lorry 34 leaving the upstream or rear end 37 of the current panel 32 in line with the downstream end 36 of the existing channel 31. Placing of the panel 32 validates a transition 104 to the panel release step 105.

Les figures 8 à 12 représentent respectivement cinq phases transitoires 8 à 12 au sein de l'étape 105 de libération.The Figures 8 to 12 respectively represent five transitional phases 8 to 12 within the release step 105.

Dans la phase transitoire 8, l'opérateur utilise le mécanisme de déplacement hors voie pour ramener le lorry 34 motorisé au dessus de la voie de liaison 38. En reculant, le lorry 34 motorisé fait reculer le lorry ferroviaire 35 sur la voie 31 en poussant sur la poutre 44. Le lorry ferroviaire 35 en prise sur les rails, agit naturellement sur la poutre 44 pour guider mécaniquement le lorry 34 motorisé vers la voie de liaison 38.In the transitional phase 8, the operator uses the off-road displacement mechanism to bring the motorized lorry 34 over the connecting lane 38. In retreating, the motorized lorry 34 moves the rail lorry 35 back onto the track 31 by pushing on the beam 44. The rail lorry 35 engaged with the rails, acts naturally on the beam 44 to mechanically guide the motorized lorry 34 towards the connecting track 38.

Dans la phase transitoire 9, l'opérateur arrête le lorry 34 motorisé qui est arrivé sur la voie de liaison 38 puis rétracte le mécanisme de déplacement hors voie pour remettre les roues ferroviaires du lorry 34 motorisé en contact avec la voie de liaison 38. L'opérateur fait alors l'opération inverse de celle de la phase 5 pour accoupler le moteur d'entraînement du lorry 34 aux roues ferroviaires.In the transitional phase 9, the operator stops the motorized lorry 34 which has arrived on the connecting lane 38 and then retracts the off-road displacement mechanism to return the railway wheels of the motorized lorry 34 in contact with the connecting lane 38. The operator then does the opposite operation to that of phase 5 to couple the lorry 34 drive motor to the railway wheels.

Dans la phase transitoire 10, l'opérateur fait refouler le lorry 34 motorisé de la voie de liaison 38 vers la voie existante 31 pour évacuer totalement la poutre 44 du dessous du panneau 32. En reculant l'extrémité avant de la poutre 44 au dessus de la voie de liaison 38 avec la barre 61 abaissée, le crochet 64 vient saisir naturellement la voie de liaison 38. Si au cours de la phase 4 ou ultérieurement, l'opérateur avait relevé la barre 61 pour faciliter le déplacement de la poutre 44, l'opérateur commande le vérin 60 de façon à baisser le crochet 64 sur la voie de liaison avant de refouler le lorry 34.In the transitional phase 10, the operator pushes the motorized lorry 34 from the linkage path 38 to the existing path 31 to completely evacuate the beam 44 from the underside of the panel 32. By pulling back the front end of the beam 44 above of the connecting track 38 with the bar 61 lowered, the hook 64 comes naturally grasp the connecting track 38. If during phase 4 or later, the operator had raised the bar 61 to facilitate the movement of the beam 44 , the operator controls the jack 60 so as to lower the hook 64 on the linkage path before pushing the lorry 34.

Dans la phase transitoire 11, l'opérateur remonte la voie de liaison 38, par exemple en commandant une rétreinte du vérin 60 qui tire alors sur le câble 59.In the transitional phase 11, the operator goes up the connecting path 38, for example by controlling a retraction of the jack 60 which then pulls on the cable 59.

Dans la phase transitoire 12, la voie de liaison 38 étant relevée au dessus du niveau de la voie 31, l'opérateur recule le lorry 34 motorisé qui ramène la voie de liaison 38 au dessus de la voie existante 31. La voie 31 sur le centre de la figure 12, est coupée pour mettre en évidence le recul du lorry 34 bien au-delà en amont de l'extrémité avale de la voie 31 qui correspond à une phase d'une autre étape du procédé exécutée éventuellement simultanément avec la phase 12 et qui sera expliquée plus loin dans la description.In the transitional phase 12, the connecting path 38 being raised above the level of the track 31, the operator moves back the motorized lorry 34 which brings the linkage track 38 over the existing track 31. The track 31 on the center of the figure 12 , is cut to highlight the decline of lorry 34 well beyond upstream of the downstream end of the channel 31 which corresponds to a phase of another step of the method possibly performed simultaneously with the phase 12 and which will be explained later in the description.

Ainsi l'évacuation du lorry 34 par l'opérateur, laisse en fin d'étape 105 de libération du panneau courant 32, l'extrémité amont 37, en d'autres termes l'extrémité arrière du panneau courant 32 qui est suspendu par les pinces 47 aux portiques extensibles de manutention 33, en aplomb de l'extrémité 36 de voie 31 existante. Un état retiré de la voie de liaison valide alors une transition 106 vers l'étape 107 de pose proprement dite.Thus the evacuation of the lorry 34 by the operator, leaves the end of step 105 of release of the current panel 32, the upstream end 37, in other words the rear end of the current panel 32 which is suspended by the grippers 47 to extendible handling gantries 33, in line with the end 36 of existing track 31. A state removed from the link path then validates a transition 106 to step 107 of actual laying.

Les figures 13 et 14 représentent respectivement deux phases de pose 13 et 14 au sein de l'étape 107 de pose du panneau courant 32.The Figures 13 and 14 respectively represent two laying phases 13 and 14 in the step 107 of laying the current panel 32.

Dans la phase de pose 13 représentée sur la partie gauche de la figure 13, l'opérateur baisse les portiques extensibles de manutention 33 de façon à poser le panneau courant 32 dans le prolongement de la voie existante 31. Lorsque le panneau 32 est posé sur le sol, l'opérateur commande une ouverture des pinces 47 de façon à décrocher les portiques extensibles de manutention 33 du panneau courant 32.In the laying phase 13 shown on the left side of the figure 13 , the operator lowers the expandable handling cranes 33 so as to put the current panel 32 in the extension of the existing lane 31. When the panel 32 is placed on the ground, the operator controls an opening of the clamps 47 so as to unhook the expandable handling gantries 33 from the current panel 32.

Dans la phase de pose 14 représentée sur la partie gauche de la figure 14, l'opérateur commande une remontée des portiques extensibles de manutention 33.In the laying phase 14 shown on the left side of the figure 14 , the operator orders a reassembly of the extensible handling gantries 33.

De la sorte, l'abaissement du panneau courant 32 sur le sol par l'opérateur, fait coïncider en fin d'étape 105, l'extrémité amont 37 du panneau courant 32 avec l'extrémité 36 de voie 31 existante. Le panneau courant 32 posé sur le sol, prolonge alors la voie 31 existante d'une longueur de panneau de voie, validant ainsi une transition 108 vers une réitération possible du procédé à partir de l'étape 101 si besoin est.In this way, the lowering of the current panel 32 on the ground by the operator, coincides at the end of step 105, the upstream end 37 of the current panel 32 with the end of the existing channel 31. The current panel 32 placed on the ground, then extends the existing channel 31 by a track panel length, thus validating a transition 108 to a possible reiteration of the process from step 101 if necessary.

Les figures 12 à 14 représentent en partie droite respectivement trois phases de transfert 16 à 18 au sein d'une étape 109 de transfert dans laquelle l'opérateur charge un panneau suivant 42 sur le lorry 34 motorisé, plus particulièrement sur la poutre 44 supportée par le lorry motorisé, à la suite de la validation de la transition 106.The Figures 12 to 14 represent in the right part respectively three transfer phases 16 to 18 within a transfer step 109 in which the operator loads a following panel 42 on the motorized lorry 34, more particularly on the beam 44 supported by the motorized lorry, following the validation of the transition 106.

Dans la première phase de transfert 16, l'opérateur amène la poutre 44 supportée par le lorry 34 motorisé sous un jeu de deuxièmes portiques extensibles de manutention 43 auxquels est suspendu le panneau suivant 42.In the first transfer phase 16, the operator brings the beam 44 supported by the motorized lorry 34 under a set of second expandable handling gantries 43 to which the following panel 42 is suspended.

Dans la deuxième phase de transfert 17, l'opérateur abaisse les portiques extensibles de manutention 43 de façon à poser le panneau suivant 42 sur la poutre 44.In the second transfer phase 17, the operator lowers the expandable handling frames 43 so as to put the next panel 42 on the beam 44.

Dans la troisième phase de transfert 18, l'opérateur relève les deuxièmes portiques extensibles de manutention 43 de façon à laisser le panneau suivant 42 sur la poutre 44.In the third transfer phase 18, the operator raises the second expandable gantry 43 to leave the next panel 42 on the beam 44.

L'étape 109 de transfert se termine par une quatrième phase de transfert 15 représentée en figure 15. Dans la phase de transfert 15, l'opérateur fait avancer le lorry 34 motorisé de façon à placer la poutre 44 qui supporte le panneau suivant sous le premier jeu de portiques extensibles de manutention 33. Une transition 110 est validée en fin d'étape 109 lorsque le panneau 42 est transféré sous les portiques extensibles de manutention 33. La validation de la transition 110 permet de reboucler l'exécution du procédé sur l'étape 101 d'acheminement dans laquelle le panneau suivant 42 devient alors le panneau courant 32.The transfer step 109 ends with a fourth transfer phase 15 represented in FIG. figure 15 . In the transfer phase 15, the operator advances the motorized lorry 34 so as to place the beam 44 which supports the following panel under the first set of expandable handling gantries 33. A transition 110 is validated at the end of step 109 when the panel 42 is transferred under the expandable handling gantries 33. The validation of the transition 110 makes it possible to loop back the execution of the method on the routing step 101 in which the next panel 42 then becomes the current panel 32.

L'exécution d'une ou plusieurs phases de transfert pendant l'étape 107 de pose, permet un gain de temps pour prolonger la voie 31.The execution of one or more transfer phases during the laying step 107, saves time to extend the track 31.

Tant que des panneaux de voie sont à poser à la suite les uns des autres pour prolonger la voie existante, chaque validation de la transition 110 active aussi une étape 111 d'approvisionnement d'un panneau d'alimentation du procédé.As long as track panels are to be laid one after the other to extend the existing track, each validation of the transition 110 also activates a step 111 of supplying a process feed panel.

Lorsque le panneau suivant 42 est transféré vers les portiques extensibles de manutention 33, les portiques extensibles de manutention 43 sont libres pour y accrocher le panneau d'alimentation qui devient alors un nouveau panneau suivant 42. L'approvisionnement peut se faire par exemple en amenant sous les portiques extensibles de manutention 43 un wagon de transport, non représenté, sur lequel sont empilés un ou plusieurs panneaux de voie pour alimenter le système.When the next panel 42 is transferred to the expandable handling gantry 33, the expandable gantry 43 is free to hang the power panel which then becomes a new panel 42. The supply can be done for example by bringing under the expandable gantries 43 a transport car, not shown, on which are stacked one or more track panels to supply the system.

Le panneau approvisionné valide une transition 112 vers l'étape 109 prête pour être activée à la suite d'une prochaine validation de la transition 106.The provisioned panel validates a transition 112 to step 109 ready to be activated following a next validation of the transition 106.

Le procédé de l'invention a été décrit pour une prolongation de voie au-delà d'une voie existante. Il va de soi que le procédé est aussi applicable pour un renouvellement de voie, l'ancienne voie étant enlevée pour laisser un terrain libre à la pose d'une nouvelle voie constituant alors une voie qui est prolongée au fur et à mesure de l'enlèvement de l'ancienne voie.The method of the invention has been described for a track extension beyond an existing track. It goes without saying that the method is also applicable for a renewal of lane, the old lane being removed to leave a free ground to the laying of a new lane then constituting a lane that is extended as and when removal of the old way.

Dans un mode de mise en oeuvre préféré, une longueur de la poutre 44 comprise, à titre purement illustratif et non limitatif, entre 31 mètres et 32 mètres, permet de soutenir des panneaux de voie de 36 mètres de long. Avantageusement, la poutre 44 est séparable en trois parties 44a, 44b et 44c qui peuvent être chargées sur une plateforme 81 de véhicule routier comme représenté par le colisage de la figure 27. Quatre barres de liaison 54 peuvent être logées dans une partie creuse de la partie de poutre 44c et quatre barres de liaisons 75, utilisables pour maintenir rigidement les portiques extensibles de manutention 43, peuvent être logées dans une partie creuse de la partie de poutre 44b. Les dimensions des éléments de système qui viennent d'être décrits, sont suffisamment faibles pour laisser la place, sur la plateforme 81 de taille standard, qui permet de ranger six patins bas 73, et six patins hauts 74. Les six patins bas 73 sont prévus pour être montés chacun à la base d'une des deux jambes 39 de portique extensible de manutention 33, de façon à faciliter l'appui des trois portiques extensibles de manutention 33 destinés à la pose. Les six patins hauts 74 sont prévus pour être montés chacun à la base d'une des deux jambes 39 de portique extensible de manutention 43, de façon à faciliter l'appui des trois portiques extensibles de manutention 43 destinés au transfert. Les patins 74 sont surélevés de façon à permettre le passage sous les trois portiques extensibles de manutention 43, d'une pile de panneaux de voie qui sont chargées sur un wagon de transport.In a preferred embodiment, a length of the beam 44 included, for purely illustrative and not limiting, between 31 meters and 32 meters, supports 36-meter long track panels. Advantageously, the beam 44 is separable into three parts 44a, 44b and 44c which can be loaded on a platform 81 of a road vehicle as represented by the packing of the figure 27 . Four connecting bars 54 may be accommodated in a hollow part of the beam portion 44c and four connecting bars 75, usable to rigidly hold the expandable handling frames 43, may be housed in a hollow portion of the beam portion 44b. The dimensions of the system elements that have just been described are sufficiently small to leave room on the platform 81 standard size, which can store six skates 73 low, and six high skates 74. The six lower skates 73 are planned to be mounted each to the base of one of the two legs 39 of expandable handling gantry 33, so as to facilitate the support of the three expandable handling gantry 33 for laying. The six upper shoes 74 are provided to be mounted each at the base of one of the two legs 39 of expandable handling gantry 43, so as to facilitate the support of the three expandable handling gantries 43 for transfer. The shoes 74 are raised so as to allow the passage under the three expandable handling gantries 43, a stack of track panels which are loaded on a transport car.

En référence au colisage de la figure 28, une deuxième plateforme 82 de véhicule routier, convient pour transporter le lorry 34 motorisé, le panneau de voie de liaison 38, nommé encore panneau de voie provisoire, le lorry ferroviaire 35 et deux portiques extensibles de manutention en position repliée.With reference to the packing of the figure 28 , a second road vehicle platform 82, is suitable for transporting the motorized lorry 34, the connecting lane panel 38, still called temporary lane board, the rail lorry 35 and two expandable handling gantries in the folded position.

En référence au colisage de la figure 29, une troisième plateforme 83 de véhicule routier, convient pour transporter quatre portiques extensibles de manutention en position repliée.With reference to the packing of the figure 29 , a third platform 83 of a road vehicle, is suitable for carrying four expandable handling gantries in the folded position.

Dans les dimensionnements du système de l'invention, on recherche tout allègement possible pour favoriser les économies d'énergie, en conservant la robustesse mécanique nécessaire à mettre en oeuvre le procédé de l'invention.In the sizing of the system of the invention, any lightening is sought to promote energy savings, retaining the mechanical robustness necessary to implement the method of the invention.

Trois camions permettent ainsi de transporter le système de l'invention par la route jusqu'à un lieu de chantier, offrant ainsi une grande souplesse d'utilisation. Dans une étape 100 initiale du procédé, le système est amené sur site, de préférence lorsque les wagons de transport des panneaux de voie sont déjà sur site pour minimiser le temps de retenue du système sur site. Dans l'étape 100, les éléments de système sont déchargés des plateformes 81, 82 et 83 puis le système est monté. A la fin de l'étape 100, le système est alors prêt pour démarrer les étapes 101 et 111 du procédé de l'invention.Three trucks thus make it possible to transport the system of the invention by road to a construction site, thus offering great flexibility of use. In an initial step 100 of the method, the system is brought to the site, preferably when the track panel transport wagons are already on site to minimize the on-site system holding time. In step 100, the system elements are unloaded from the platforms 81, 82 and 83 and the system is mounted. At the end of step 100, the system is then ready to start steps 101 and 111 of the method of the invention.

On remarque que le procédé et le système qui viennent d'être décrits, sont modulaires et peuvent être adaptés à différentes longueurs de panneaux de voie. La description a été faite en considérant des panneaux de 36 mètres qui nécessitent trois portiques extensibles de manutention. Pour travailler avec des panneaux de 24 mètres, il est possible de ne considérer que des jeux de deux portiques extensibles de manutention ainsi que de réduire la longueur de la poutre en mettant bout à bout la partie avant 44a et la partie arrière 44c sans monter la partie central 44b de la poutre 44.Note that the method and system just described, are modular and can be adapted to different lengths of track panels. The description was made considering 36-meter panels that require three expandable gantries handling. To work with panels of 24 meters, it is possible to consider only sets of two expandable gantry handling as well as reduce the length of the beam by putting end to end the front portion 44a and the rear portion 44c without mounting the central portion 44b of the beam 44.

Le procédé de l'invention permet d'obtenir à faibles coûts et rapidement, des voies de chemin de fer d'excellente qualité.The method of the invention makes it possible to obtain at low cost and quickly, railways of excellent quality.
