Description

L'invention concerne les véhicules ferroviaires utilisés pour la pose ou la dépose de voies ferrées.The invention relates to railway vehicles used for laying or removing railway tracks.

Parmi les différents matériels mis en oeuvre pour poser les voies de chemin de fer, on utilise un véhicule usuellement appelé "poutre de pose" et dont une vue générale de profil est donnée sur la figure 1. Ce véhicule comporte essentiellement deux paires de montants latéraux 1, 2 disposés près des extrémités du châssis 3. Sur ces montants latéraux est posée une flèche 4 roulante munie d'un palonnier de levage 5 qui permet de transborder des tronçons complets (rails + traverses) de voie 6 entreposées sur le châssis 1 et les poser en avant ou en arrière du véhicule sur une plate-forme de pose.Among the various materials used to lay the railway tracks, a vehicle usually called a "laying beam" is used, a general profile view of which is given in FIG. 1. This vehicle essentially comprises two pairs of lateral uprights 1, 2 arranged near the ends of the chassis 3. On these lateral uprights is placed a rolling jib 4 provided with a lifting beam 5 which makes it possible to tranship complete sections (rails + sleepers) of track 6 stored on the chassis 1 and place them in front of or behind the vehicle on a laying platform.

La flèche mesure environ 40m de long et permet de poser des tronçons de voie d'une longueur comprise entre 12 et 24m, usuellement appelés "longueurs de voie". Elle ne peut se déplacer que dans l'axe de la voie.The boom is approximately 40m long and allows sections of track between 12 and 24m in length to be laid, usually called "track lengths". It can only move in the axis of the track.

En position extrême, le palonnier 5 , qui sert à déposer la longueur de voie sur la plate-forme peut se trouver à une hauteur de 6m au-dessus de la plate-forme de pose 7.In the extreme position, the lifting beam 5, which is used to deposit the track length on the platform, can be at a height of 6m above the laying platform 7.

Un appareil de ce type est décrit et représenté dans le documet RAILWAY GAZETTE, vol. 126 n° 3, 6 février 1970, Londres, pages 102-103.An apparatus of this type is described and represented in the document RAILWAY GAZETTE, vol. 126 No. 3, February 6, 1970, London, pages 102-103.

Il est fondamentalement différent des autres appareils de manutention ferroviaires telles que les grues tournantes qui font l'objet du brevet GB 2.139.976 et qui, montées à pivotement autour d'un axe vertical sont destinées à travailler non pas dans l'axe de pose mais latéralement à cet axe.It is fundamentally different from other railway handling devices such as the rotating cranes which are the subject of GB patent 2,139,976 and which, pivotally mounted around a vertical axis are intended to work not in the laying axis but laterally to this axis.

Avec une poutre de pose telle que décrite dans le document RAILWAY GAZETTE la pose des longueurs de voie sur plate-forme horizontale s'effectue sans problème particulier à une cadence rapide.With a laying beam as described in the RAILWAY GAZETTE document, the installation of track lengths on a horizontal platform is carried out without any particular problem at a rapid rate.

Par contre, lorsque l'on pose des longueurs de voie sur des plates-formes pentées (par exemple dans les courbes des voies en renouvellemnt ou bien pour les voies sur plate-forme neuve en sable compacté pentée à 4cm par mètre pour l'écoulement des eaux), compte-tenu de l'inclinaison prise par le véhicule, la longueur de voie 6 portée par le palonnier 5 est déposée sur la plate-forme avec un décalage important par rapport à l'axe de la voie (par exemple, pour une plate-forme T.G.V., ce décalage est compris entre 20 et 30cm).On the other hand, when laying lengths of track on sloping platforms (for example in the curves of tracks in renewal or else for tracks on new platform in compacted sand steep at 4cm per meter for flow water), taking into account the inclination taken by the vehicle, the track length 6 carried by the lifter 5 is deposited on the platform with a significant offset relative to the axis of the track (for example, for a TGV platform, this offset is between 20 and 30cm).

Pour rattrapper ce décalage, le seul moyen actuellement utilisé consiste à faire repousser la longueur de voie par des hommes équipés de leviers appelés pinces à riper, ce qui ralentit considérablement la cadence de pose, renchérit le coût de pose et risque de détériorer la plate-forme.To make up for this difference, the only way currently used is to push the length of the track back by men equipped with levers called pliers for riper, which considerably slows down the laying rate, increases the laying cost and risks damaging the platform. form.

Selon l'invention cet inconvénient est résolu par le fait que le châssis du véhicule est articulé sur ses boogies par des moyens lui permettant de faire varier l'angle relatif entre le châssis et les boogies de manière à rattraper le dévers de la plate-forme de pose, de sorte que les poulies porteuses du palonnier soient toujours exactement à la verticale de l'axe théorique de la voie, le palonnier restant parfaitement horizontal.According to the invention this drawback is solved by the fact that the chassis of the vehicle is articulated on its boogies by means allowing it to vary the relative angle between the chassis and the boogies so as to catch up with the cant of the platform installation, so that the pulleys carrying the spreader are always exactly vertical to the theoretical axis of the track, the spreader remaining perfectly horizontal.

De préférence, l'articulation entre un boogie et le châssis de la poutre de pose est constituée d'une part par un pivot semi-sphérique disposé au point de symétrie axial du boogie et d'autre part par au moins deux vérins hydrauliques disposés de part et d'autre du véhicule et dont une extrémité est solidaire du boogie tandis que l'autre est solidaire du châssis.Preferably, the articulation between a boogie and the chassis of the laying beam consists firstly of a semi-spherical pivot arranged at the point of axial symmetry of the boogie and secondly by at least two hydraulic cylinders arranged on either side of the vehicle and one end of which is secured to the boogie while the other is secured to the chassis.

De la sorte, le pivot sphérique autorise à la fois une rotation du boogie dans le plan horizontal par rapport à la direction d'avancement et une inclinaison du châssis par rapport au boogie dans le plan vertical.In this way, the spherical pivot allows both a rotation of the boogie in the horizontal plane relative to the direction of advance and an inclination of the frame relative to the boogie in the vertical plane.

Les vérins servent à régler et fixer la valeur de l'angle relatif du boogie et du châssis et empêchent leur désolidarisation accidentelle.The cylinders are used to adjust and fix the value of the relative angle of the boogie and the chassis and prevent their accidental detachment.

Selon un exemple de réalisation préférentiel un axe de sécurité est disposé au travers du pivot semi-sphérique.According to a preferred embodiment, a safety axis is arranged through the semi-spherical pivot.

L'invention sera mieux comprise à l'aide de la description d'exemples de réalisation qui va suivre avec référence aux dessins annexés sur lesquels :

  • La figure 1 est une vue générale de profil d'une poutre de pose de rail, objet de l'invention.
  • La figure 2 est une vue schématique agrandie en coupe transversale d'une poutre selon la figure 1 avec arrachement partiel montrant la liaison entre le châssis et le boogie.
  • La figure 3 est une vue en coupe encore agrandie selon la figure 2, montrant un premier exemple de réalisation du pivot semi-sphérique du dispositif de liaison entre le châssis et le boogie selon l'invention.
  • La figure 4 est une vue analogue à la figure 2 montrant un deuxième exemple de réalisation de la liaison entre le châssis et le boogie selon l'invention.
  • La figure 5 est une vue analogue à la figure 3 montrant le pivot selon l'exemple de réalisation de la figure 4.
The invention will be better understood with the aid of the description of exemplary embodiments which will follow with reference to the appended drawings in which:
  • Figure 1 is a general profile view of a rail laying beam, object of the invention.
  • Figure 2 is an enlarged schematic view in cross section of a beam according to Figure 1 with partial cutaway showing the connection between the frame and the boogie.
  • Figure 3 is a further enlarged sectional view according to Figure 2, showing a first embodiment of the semi-spherical pivot of the connection device between the chassis and the boogie according to the invention.
  • Figure 4 is a view similar to Figure 2 showing a second embodiment of the connection between the chassis and the boogie according to the invention.
  • FIG. 5 is a view similar to FIG. 3 showing the pivot according to the embodiment of FIG. 4.

Sur la figure 2, on voit que dans les poutres de pose classiques, le boogie 8 est solidarisé au châssis 3 par l'intermédiaire d'un pivot 9 traversant une selle 10 fixée sur le cadre du boogie et un massif circulaire mâle 11 fixé sous le châssis 3.In Figure 2, we see that in conventional laying beams, the boogie 8 is secured to the frame 3 by means of a pivot 9 passing through a saddle 10 fixed on the frame of the boogie and a male circular solid mass 11 fixed under chassis 3.

La partie protubérante du massif 11 vient se loger dans la cuvette circulaire de la selle 10. L'ensemble est tenu par un écrou 12 sur l'extrémité filetée du pivot 9, ledit écrou prenant appui sur le plancher du châssis 3.The protruding part of the block 11 is housed in the circular bowl of the saddle 10. The assembly is held by a nut 12 on the threaded end of the pivot 9, said nut bearing on the floor of the chassis 3.

Comme cela est également représenté sur la figure 2, lorque la voie sur laquelle roule la poutre de pose est en dévers, l'angle de dévers a induit une déviation correspondante de la verticale 13 par rapport à l'axe vertical médian 14 du véhicule.As also shown in FIG. 2, when the track on which the laying beam rolls is on a slope, the slope angle has induced a corresponding deviation from the vertical 13 relative to the median vertical axis 14 of the vehicle.

Le tronçon de voie 6 porté par le palonnier sera alors posé sur la plate-forme 7 avec un écart par rapport à l'axe de pose 15, d'où la nécessité d'une intervention ultérieure pour réaligner le tronçon déposé.The track section 6 carried by the lifter will then be placed on the platform 7 with a deviation from the laying axis 15, hence the need for subsequent intervention to realign the deposited section.

L'invention procure des moyens pour que le châssis 3 de la poutre de pose puisse conserver son horizontalité indépendamment du dévers du boogie.The invention provides means so that the frame 3 of the laying beam can maintain its horizontality independently of the slope of the boogie.

A cet effet, selon l'exemple de réalisation de la figure 3, on a remplacé le pivot 9, la selle 10 et le massif 11 de l'exemple de réalisation précédent par un pivot semi-sphérique constitué d'une cuvette femelle 16 solidaire du cadre du boogie 8 coopérant avec un coupole mâle 17 fixée sous le châssis 3.For this purpose, according to the embodiment of Figure 3, we replaced the pivot 9, the saddle 10 and the mas sif 11 of the previous embodiment by a semi-spherical pivot consisting of a female bowl 16 secured to the frame of the boogie 8 cooperating with a male dome 17 fixed under the chassis 3.

En outre, de part et d'autre de la poutre sensiblement au niveau du pivot semi-sphérique 16, 17 sont disposés deux paires de vérins hydrauliques 18, 19 (voir figure 4) qui relient le boogie 8 au châssis 3.In addition, on either side of the beam substantially at the level of the semi-spherical pivot 16, 17 are arranged two pairs of hydraulic cylinders 18, 19 (see FIG. 4) which connect the boogie 8 to the chassis 3.

Ces vérins ont pour double fonction, d'assurer le basculement du châssis par rapport au boogie 8 pour rattraper tout dévers et d'empêcher la désolidarisation accidentelle des deux parties du pivot semi-sphérique 16, 17.These jacks have the double function of ensuring the tilting of the chassis relative to the boogie 8 to catch any slope and of preventing the accidental separation of the two parts of the semi-spherical pivot 16, 17.

Ainsi, quelle que soit la pente transversale de la voie sur laquelle circule la poutre de pose, le châssis 3 restera horizontal et les tronçons de voie 6 seront posés dans l'axe théorique 15 de la voie, ce qui supprime l'opération manuelle de réalignement.Thus, whatever the transverse slope of the track on which the laying beam travels, the frame 3 will remain horizontal and the track sections 6 will be laid in the theoretical axis 15 of the track, which eliminates the manual operation of realignment.

Selon un deuxième exemple de réalisation représenté aux figures 4 et 5, on assure la solidarisation entre le boogie 8 et le châssis 3 même en cas de défaillance du circuit d'alimentation hydraulique des vérins au moyen d'un axe vertical 20 fixé au cadre du boogie 8 traversant les deux demi-sphères 16, 17 du pivot semi-sphérique et dont l'extrémité porte un écrou 22 bloquant une bague d'arrêt 21 logée à l'intérieur de la coupole 17.According to a second embodiment shown in Figures 4 and 5, it ensures the connection between the boogie 8 and the chassis 3 even in the event of failure of the hydraulic supply circuit of the jacks by means of a vertical axis 20 fixed to the frame of the boogie 8 passing through the two half-spheres 16, 17 of the semi-spherical pivot and the end of which carries a nut 22 blocking a stop ring 21 housed inside the dome 17.

Le passage axial de la cuvette 16 est conformé en manchon, tandis que le passage axial de la coupole 17 est d'un diamètre suffisant pour autoriser le débattement dudit manchon.The axial passage of the bowl 16 is shaped as a sleeve, while the axial passage of the dome 17 is of sufficient diameter to allow the movement of said sleeve.

L'extrémité de l'axe 20 aboutit dans une ouverture pratiquée dans le plancher du châssis, ladite ouverture étant suffisamment large pour autoriser les oscillations de l'axe 20 en fonction des mouvements relatifs du boogie 8 et du châssis 3.The end of the axis 20 ends in an opening made in the floor of the chassis, said opening being wide enough to allow the oscillations of the axis 20 as a function of the relative movements of the boogie 8 and the chassis 3.

Le serrage de l'écrou 20 et de la bague d'arrêt 21 est tel qu'il autorise un coulissement relatif de la coupole 17 dans la cuvette 16.The tightening of the nut 20 and the stop ring 21 is such that it allows relative sliding of the dome 17 in the bowl 16.

Cette disposition exclut une désolidarisation accidentelle du boogie et du châssis même en cas de défaillance du sytème d'alimentation des vérins 17 et 18.This provision excludes accidental separation of the boogie and the chassis even in the event of failure of the supply system of the cylinders 17 and 18.

Elle autorise à n'utiliser les vérins 17 et 18 que pour régler l'angle relatif du boogie et du châssis en fonction du dévers de la voie à poser.It authorizes the use of jacks 17 and 18 only to adjust the relative angle of the boogie and the chassis according to the slope of the track to be laid.

Dans ce cas, une fois le réglage obtenu, on le fixe en utilisant des cales d'épaisseur appropriée 23 (dénommées lisoirs) , placées entre le boogie et le châssis.In this case, once the adjustment has been obtained, it is fixed using shims of appropriate thickness 23 (called reading boards), placed between the boogie and the chassis.

L'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.The invention is not limited to the embodiments which have just been described.

En particulier, il est possible sans sortir du cadre de l'invention, d'inverser la disposition du pivot semi-sphérique en plaçant la cuvette 16 sur le châssis 3 et la coupole 17 sur le boogie 8.In particular, it is possible, without departing from the scope of the invention, to reverse the arrangement of the semi-spherical pivot by placing the bowl 16 on the chassis 3 and the dome 17 on the boogie 8.

De même, les vérins hydrauliques 18, 19 peuvent être remplacés par des vérins à vis ou des ridoirs sans sortir du cadre de l'invention.Similarly, the hydraulic cylinders 18, 19 can be replaced by screw jacks or turnbuckles without departing from the scope of the invention.
