Description

L'invention concerne un train articulé de renouvellement des voies ferrées composé d'une unité de démontage, d'une unité de transport, d'une unité de travail et d'une unité de pose des rails, l'unité de travail étant équipée d'une installation de dépose des traverses et de pose des traverses.The invention relates to an articulated train for renewing railway tracks composed of a dismantling unit, a transport unit, a working unit and a rail laying unit, the working unit being equipped an installation for removing ties and installing ties.

Un tel wagon articulé est déjà décrit dans la demande de brevet antérieure EP 88810568.1 de la même demande­resse, comme partie d'un train de renouvellement d'une voie de chemin de fer. Un tel train de renouvellement effectue toutes les opérations simultanément, c'est-à-­dire l'écartement des anciens rails, la dépose des anciennes traverses et la pose des nouvelles traverses les unes après les autres, ainsi que la mise en place des nouveaux rails qui ont été placés auparavant à côté de la voie à renouveler.Such an articulated wagon is already described in the previous patent application EP 88810568.1 from the same applicant, as part of a train for renewing a railway track. Such a renewal train performs all the operations simultaneously, that is to say the spacing of the old rails, the removal of the old sleepers and the laying of the new sleepers one after the other, as well as the installation of the new rails that were previously placed next to the track to be renewed.

Ledit train décrit dans la demande de brevet sus-­mentionnée est conçu de manière que seulement l'unité de travail est construite sous forme de wagon de chemin de fer, munie, à son extrémité postérieure, d'un boggie dont les roues sont escamotables et remplacées par des chenilles lorsque le train travaille, et que l'unité de pose des rails est mobile et s'appuie d'une part sur l'extrémité du wagon et d'autre part sur un support roulant qui se déplace sur la voie, ladite unité de pose des rails étant chargée sur le wagon pour la marche haut le pied. L'extrémité antérieure du wagon qui est dépourvue de boggie est articulée à un véhicule de stockage s'appuyant, de façon pivotante, sur le châssis de ce véhicule de stockage qui représente ladite unité de transport et qui comporte également des installations pour démonter les fixations des rails aux traverses. L'unité de pose des rails mobile de ce train consiste en au moins une poutre à laquelle sont suspendus des éléments de pose, cette poutre s'appuyant et étant déplaçable sur le wagon par des galets. Selon une autre forme d'exécution proposée dans cette demande de brevet, cette unité de pose des rails consiste en une poutre téléscopique sur laquelle sont suspendus les éléments de pose, l'extrémité déployée de ladite poutre s'appuyant, en position de travail, sur le support roulant tandis que l'autre extrémité est suspendue à un cadre monté à l'extrémité adjacente du wagon; pour la marche haut le pied, les éléments de cette poutre sont rétractés l'un dans l'autre et se trouvent entièrement chargés sur le wagon. Pour transporter les nouvelles traverses à l'emplacement de travail et enlever les anciennes traverses, il est connu d'avoir des portiques qui roulent sur des chemins de roulement montés en continu sur les unités de démontage, de transport et de travail ainsi que sur les autres véhicules de transport des traverses.Said train described in the aforementioned patent application is designed so that only the work unit is constructed in the form of a railway wagon, provided at its rear end with a bogie, the wheels of which are retractable and replaced by tracks when the train is working, and the rail laying unit is mobile and rests on the one hand on the end of the wagon and on the other hand on a rolling support which moves on the track, said rail laying unit being loaded onto the wagon for walking high. The front end of the wagon which is devoid of a bogie is articulated to a storage vehicle which is pivotally supported on the chassis of this storage vehicle which represents said transport unit and which also comprises installations for dismantling the rail fasteners to the sleepers. The unit for laying the mobile rails of this train consists of at least one beam from which hanging laying elements are suspended, this beam resting and being movable on the wagon by rollers. According to another embodiment proposed in this patent application, this rail laying unit consists of a telescopic beam on which the laying elements are suspended, the deployed end of said beam resting, in the working position, on the rolling support while the other end is suspended from a frame mounted at the adjacent end of the wagon; for walking high, the elements of this beam are retracted one inside the other and are fully loaded on the wagon. To transport the new sleepers to the work site and remove the old sleepers, it is known to have gantries that run on rolling tracks mounted continuously on the dismantling, transport and work units as well as on the other sleeper transport vehicles.

Ce train de renouvellement décrit dans la demande de brevet européen mentionnée présente l'avantage de réduire la longueur des unités de travail à celle d'un seul wagon en marche haut le pied, et de permettre d'adapter la dimension des éléments de l'unité mobile aux conditions et aux efforts de travail, ce qui permet d'échapper aux exigences imposées à un wagon de chemin de fer.This renewal train described in the European patent application mentioned has the advantage of reducing the length of the working units to that of a single wagon running high, and to allow the size of the elements of the mobile unit with working conditions and efforts, which makes it possible to escape the requirements imposed on a railway wagon.

Le but de la présente invention consiste à perfection­ner ce train de renouvellement par une construction plus simple et plus compacte rendant plus facile l'adaptation de la machine aux conditions de travail.The object of the present invention is to improve this renewal train by a simpler and more compact construction making it easier to adapt the machine to working conditions.

Pour atteindre ce but, l'invention est caractérisée par le fait que l'installation de pose des traverses est montée en porte-à-faux à l'extrémité postérieure de l'unité de travail dans un cadre pivotant maintenu en position de travail par un asservissement, de telle manière que les traverses puissent être posées dans la position voulue.To achieve this object, the invention is characterized in that the installation for installing the sleepers is cantilevered at the rear end of the working unit in a pivoting frame maintained in the working position by a servo, so that the crosspieces can be placed in the desired position.

Dans une forme d'exécution préférable, l'articulation du cadre pivotant est déplaçable transversalement par rapport à l'axe longitudinal de l'unité de travail et par rapport à l'ancienne voie, de manière que les nouvelles traverses puissent être posées correctement si l'axe de la nouvelle doit être déplacé dans le sens transversal, par exemple pour augmenter l'écart entre cette voie et la voie parallèle.In a preferable embodiment, the articulation of the pivoting frame is movable transversely with respect to the longitudinal axis of the working unit and with respect to the old track, so that the new sleepers can be laid correctly if the axis of the news must be moved in the transverse direction, for example to increase the gap between this channel and the parallel channel.

Pour simplifier encore la construction et réduire le poids des installations de pose de rails, le présent train de renouvellement ne comporte plus les poutres de liaison entre wagon de travail et chariot pose-rails décrites dans la demande de brevet 88810568.1. Selon l'une des formes d'exécution possibles, l'unité de pose des rails est construite comme chariot équipé d'un essieu escamotable, lequel est abaissé en position de travail. Selon une autre forme d'exécution possible, l'unité de pose des rails est réalisée sous forme de wagon de chemin de fer. Ce chariot, respectivement ce wagon, est attelé en marche haut le pied à l'unité de travail et porte l'installation de pose des traverses par l'intermédiaire du cadre pivotant. En position de travail, cette unité de pose des rails est tractée par l'unité de travail au moyen d'un câble ou d'une barre de traction télescopique, de telle manière que la distance de pose puisse être adaptée aux conditions de travail.To further simplify the construction and reduce the weight of the rail laying installations, the present renewal train no longer comprises the connecting beams between working wagon and rail-laying trolley described in patent application 88810568.1. According to one of the possible embodiments, the rail laying unit is constructed as a carriage equipped with a retractable axle, which is lowered into the working position. According to another possible embodiment, the rail laying unit is produced in the form of a railway wagon. This trolley, respectively this wagon, is hitched in high gear to the work unit and carries the installation of sleepers through the pivoting frame. In the working position, this rail laying unit is towed by the working unit by means of a cable or a telescopic drawbar, so that the installation distance can be adapted to the working conditions.

Ledit cadre pivotant peut en outre être muni de pinces à galet pour la manutention des anciens et des nouveaux rails.Said pivoting frame can also be fitted with roller clamps for handling the old and new rails.

Les figures 1a à 1d montrent un train de renouvellement articulé selon l'invention, figures sur lesquelles on voit: un wagon de travail 1 formant l'unité de travail, situé au dessus de la zone de renouvellement, un wagon de transport 2 formant l'unité de transport, sur les anciens rails R1, un wagon de démontage 3 formant l'unité de démontage, sur les anciens rails R1, un chariot de pose de rails 4 formant l'unité de pose des rails, sur les nouveaux rails R2 et seulement l'un des plusieurs wagons de stockage 5 pour les traverses, situés à la tête du train qui avance dans le sens de la flèche indiquée figures 1a et 1c.FIGS. 1a to 1d show an articulated renewal train according to the invention, figures in which we see: a working wagon 1 forming the working unit, located above the renewal zone, a transport wagon 2 forming l transport unit, on the old rails R1, a dismantling wagon 3 forming the dismantling unit, on the old rails R1, a carriage for laying rails 4 forming the unit for laying the rails, on the new rails R2 and only one of the several storage wagons 5 for the sleepers, located at the head of the train which advances in the direction of the arrow indicated in FIGS. 1a and 1c.

Le wagon de travail 1 se compose de deux poutres parallèles 7 dont l'écartement est variable, par exemple au moyen d'un vérin hydraulique 7c. Ces poutres sont reliées à un châssis 7a muni, à son extrémité postérieure, d'un boggie 10 à deux essieux 11 entre lesquels est monté un châssis à chenilles automotrices 12 escamotables. Selon une autre forme d'exécution, non représentée sur les figures 1a à 1c, les chenilles sont fixées au châssis et ce sont les essieux qui sont escamotables. L'extrémité antérieure de ce wagon de travail 1, dépourvue de boggie, s'appuie sur le wagon de transport 2, wagon auquel elle est reliée par une articulation 6.The working wagon 1 consists of two parallel beams 7 whose spacing is variable, for example by means of a hydraulic cylinder 7c. These beams are connected to a chassis 7a provided at its rear end with a bogie 10 with two axles 11 between which is mounted a chassis with self-propelled tracks 12. According to another embodiment, no shown in Figures 1a to 1c, the tracks are fixed to the chassis and it is the axles which are retractable. The front end of this working wagon 1, devoid of a bogie, rests on the transport wagon 2, a wagon to which it is connected by an articulation 6.

Dans la position de travail, le châssis à chenilles 12 est abaissé par des moyens hydrauliques pour rouler sur le ballast B, comme montré à la figure 1c. En position de marche haut le pied, figure 9, les chenilles 12 sont relevées et les essieux 11 portent sur le rail.In the working position, the tracked chassis 12 is lowered by hydraulic means to roll on the ballast B, as shown in Figure 1c. In the up position, Figure 9, the tracks 12 are raised and the axles 11 bear on the rail.

Les poutres 7 du wagon de travail 1 sont munies du chemin de roulement 8 qui se prolonge sur le wagon de transport 2, sur le wagon de démontage 3 ainsi que sur les wagons 5 de stockage des traverses, pour qu'un portique 9, équipé d'une poutre 9a pour le transport des traverses, puisse se déplacer le long du train. Sur ce wagon de travail 1 sont montés l'installation de dépose des anciens rails R1, comprenant des pinces à rails 14 et 28, et des rouleaux de guidage 15 pour ces rails; ainsi que l'installation pour la dépose des anciennes traverses T1 et enfin les éléments de transport et de stockage intermédiaire des traverses. En outre, à l'extrémité où le wagon de travail 1 est articulé au wagon de transport 2, on a prévu un essieu auxiliaire 13 qui est levé pendant le travail et qui entre en fonction seulement lors du déplacement du train.The beams 7 of the working wagon 1 are provided with the raceway 8 which extends on the transport wagon 2, on the dismantling wagon 3 as well as on the sleeper wagons 5, so that a gantry 9, equipped a beam 9a for the transport of sleepers, can move along the train. On this working wagon 1 are mounted the installation for removing the old rails R1, comprising rail clips 14 and 28, and guide rollers 15 for these rails; as well as the installation for removing the old T1 sleepers and finally the transport and intermediate storage elements for the sleepers. In addition, at the end where the working wagon 1 is articulated to the transport wagon 2, an auxiliary axle 13 is provided which is raised during work and which comes into operation only when the train is moving.

La manutention des rails se fait par des pinces à rails 14 et 28, et des rouleaux de guidage 15 réglables en hauteur et en largeur. Les anciennes traverses T1 sont démontées une à une à l'aide d'une piocheuse 17 et transmises par un organe 17a au transporteur intermé­diaire 18 et, ensuite, par l'intermédiaire d'un élévateur 18a, à un transporteur de stockage 19 duquel elles sont transportées par le portique 9 à l'un des wagons de transport 5. Derrière la piocheuse 17 se trouve une lame d'égalisation 16 destinée à égaliser le ballast B.The rails are handled by rail clamps 14 and 28, and guide rollers 15 adjustable in height and in width. The old T1 sleepers are dismantled one by one using a picker 17 and transmitted by a member 17a to the intermediate conveyor 18 and, then, via an elevator 18a, to a storage conveyor 19 from which they are transported by the gantry 9 to one of the transport wagons 5. Behind the picker 17 is an equalization blade 16 intended to equalize the ballast B.

En queue de wagon de travail 1 (figures 1c et 2), en porte-à-faux, sont logés dans un cadre 20, pivotant autour d'un axe d'articulation 21, l'installation de pose des nouvelles traverses T2 composée d'une pince coulissante 22, d'un transporteur vertical 23 et de l'élément de pose 24. Ce cadre 20 repose sur le châssis 7a (figure 9) auquel il est relié par l'articulation 21. Le cadre 20 est en outre muni, à son extrémité postérieure, des pinces à rails 28 et d'une cabine 26 (figures 1c et 9) déplaçable en hauteur le long des montants 27 et abaissée pendant le travail.At the tail end of working wagon 1 (FIGS. 1c and 2), in overhang, are housed in a frame 20, pivoting around a hinge pin 21, the installation for installing the new T2 sleepers composed of '' a sliding clamp 22, a vertical conveyor 23 and the laying element 24. This frame 20 rests on the frame 7a (Figure 9) to which it is connected by the hinge 21. The frame 20 is further provided , at its rear end, rail clamps 28 and a cabin 26 (Figures 1c and 9) movable in height along the uprights 27 and lowered during work.

Devant l'élément de pose, une fraise de ballast 25 montée au châssis 7a sert à égaliser la plate-forme immédiatement avant la pose des nouvelles traverses T2. L'installation de pose des traverses est alimentée par un transporteur de stockage 29 qui reçoit lui-même les nouvelles traverses T2 stockées sur l'un des wagons de stockage 5, au moyen du portique 9.In front of the laying element, a ballast cutter 25 mounted on the chassis 7a is used to level the platform immediately before the installation of the new T2 crosspieces. The installation for laying the sleepers is supplied by a storage conveyor 29 which itself receives the new sleepers T2 stored on one of the storage wagons 5, by means of the gantry 9.

Pour la pose des nouvelles traverses T2 dans les courbes, le cadre 20 peut être pivoté et ripé (figures 3 et 4). La possibilité de ripage, c'est à dire de déplacement transversal, est nécessaire si l'on veut poser les nouvelles traverses correctement sur un nouvel axe déplacé de la voie, comme cela est notamment le cas si l'on veut augmenter l'écart entre la voie à renouveler et une voie parallèle. La figure 4 montre un ripage d'une distance d de l'axe de la nouvelle voie V2 déplacé par rapport à l'axe de l'ancienne voie V1.For the installation of the new crosspieces T2 in the curves, the frame 20 can be pivoted and swiveled (Figures 3 and 4). The possibility of shifting, that is to say of transverse displacement, is necessary if one wants to pose the new sleepers correctly on a new axis displaced from the track, as it is in particular the case if one wants to increase the gap between the way to renew and a parallel track. FIG. 4 shows a shifting of a distance d from the axis of the new channel V2 displaced relative to the axis of the old channel V1.

L'articulation du cadre 20, comme montré en détail figures 5 et 6, est réalisée par un axe d'articulation 21a logé dans un palier d'une pièce 38 qui elle-même peut être déplacée dans le sens transversal par l'intermédiaire d'un vérin 39, dans l'espace limité par deux parties parallèles du châssis 7a.The articulation of the frame 20, as shown in detail in FIGS. 5 and 6, is produced by an articulation pin 21a housed in a bearing of a part 38 which itself can be moved in the transverse direction by means of d 'a jack 39, in the space limited by two parallel parts of the chassis 7a.

Le pivotement du cadre 20 est commandé automatiquement par un palpeur 30 (figures 1c et 7) qui suit et mesure la position de l'ancienne voie par rapport au châssis 7a, et par une unité de calcul, comme cela sera encore décrit ultérieurement. Dans l'exemple considéré, ledit palpeur 30 et l'unité de calcul ont également la fonction de système de guidage des chenilles, on économise ainsi un système de guidage séparé pour l'installation de pose des traverses; mais, en principe, on peut prévoir un système de guidage pour l'installation de pose des traverses indépendant de celui des chenilles. Le palpeur 30 est relié à la barre de liaison 7b des poutres 7 par un vérin de mesure 31 opérant devant la piocheuse 17. Ce palpeur comporte deux patins 30a qui sont guidés par l'ancienne voie, à savoir, comme le montre la figure 7, par les selles 32 des anciennes traverses T1 dépourvues de l'ancien rail. La distance de pose est déterminée par une roue de mesure placée en tête de machine.The pivoting of the frame 20 is automatically controlled by a probe 30 (Figures 1c and 7) which tracks and measures the position of the old track relative to the chassis 7a, and by a calculation unit, as will be described further below. In the example considered, said probe 30 and the calculation unit also have the function of a guide system for the tracks, thus saving a separate guide system for the installation of laying the sleepers; but, in principle, a guide system can be provided for the installation of laying the sleepers independent of that of the tracks. The probe 30 is connected to the connecting bar 7b of the beams 7 by a measuring cylinder 31 operating in front of the picker 17. This probe has two pads 30a which are guided by the old track, namely, as shown in FIG. 7 , by the saddles 32 of the old cross-members T1 devoid of the old rail. The installation distance is determined by a measuring wheel placed at the machine head.

Le wagon de transport 2 (figure 1b), avec chemin de roulement 8, s'appuie sur des boggies 33, dont un est motorisé. Ce wagon est relié en tête au wagon de démontage 3 (figure 1a) par une articulation 34. Ce wagon de transport 2 est équipé du groupe d'entraînement 35 et de l'installation de ramassage et de stockage des fixations des rails 36, 37. Le portique 9 automoteur permet la prise et le transport de trente traverses.The transport wagon 2 (FIG. 1b), with raceway 8, is supported on bogies 33, one of which is motorized. This wagon is connected at the head to the dismantling wagon 3 (FIG. 1a) by a hinge 34. This transport wagon 2 is equipped with the drive unit 35 and with the installation for collecting and storing the fastenings of the rails 36, 37. The self-propelled gantry 9 makes it possible to pick up and transport thirty sleepers.

Le chariot pose-rails 4 (figures 1d et 9), muni d'un premier essieu 40 et d'un deuxième essieu 41 escamotable, est attelé pendant le travail au wagon de travail 1 par un câble 45 et, en marche haut le pied, avec l'essieu 41 levé, comme bissel en queue du wagon de travail 1. Le châssis du chariot 4 est équipé des pinces à rails 42 pour la pose des nouveaux rails R2 et de rouleaux de guidage 43 pour le rangement des anciens rails R1. Pendant ces travaux, ces rails sont guidés par des pinces à rails 28 montées à l'extrémité postérieure du cadre pivotant 20. Par ailleurs, le chariot 4 est également équipé d'une cabine 44 mobile sur son châssis; pendant le travail, elles est placée en tête du chariot 4 (figure 1d) et, pendant le transport, en queue (figure 9). En outre, le chariot 4 est muni d'un groupe d'entraînement 47 pour l'alimentation des éléments de travail de ce chariot.The rail-laying trolley 4 (FIGS. 1d and 9), fitted with a first axle 40 and a second retractable axle 41, is coupled during work to the working wagon 1 by a cable 45 and, in high gear , with the axle 41 raised, as a bissel at the tail of the working wagon 1. The chassis of the carriage 4 is equipped with rail clamps 42 for the installation of the new rails R2 and of guide rollers 43 for the storage of the old rails R1 . During these works, these rails are guided by rail clamps 28 mounted at the rear end of the pivoting frame 20. Furthermore, the carriage 4 is also equipped with a cabin 44 movable on its chassis; during work, they are placed at the head of the carriage 4 (Figure 1d) and, during transport, at the tail (Figure 9). In addition, the carriage 4 is provided with a drive group 47 for supplying the working elements of this carriage.

En marche haut le pied, le chariot 4 porte l'instal­lation de pose des traverses par l'intermédiaire du cadre 20, comme indiqué à la figure 9, ainsi que les pinces à rails 28 et la cabine 26.In high gear, the carriage 4 carries the installation for installing the crosspieces through the frame 20, as shown in FIG. 9, as well as the rail clamps 28 and the cabin 26.

La mise en oeuvre du wagon articulé de renouvellement s'effectue de la manière suivante:The implementation of the articulated renewal wagon is carried out as follows:

Au début du chantier, les fixations des anciens rails R1 sont démontées. Ces anciens rails sont écartés à l'aide de pinces à rails 14 et les anciennes traverses T1 sont enlevées une à une par la piocheuse 17 et acheminées par l'organe 17a au transporteur intermédiaire 18 et, ensuite, par l'élévateur 18a, au transporteur de stockage 19. Derrière l'installation de déposé, le ballast est égalisé par la lame d'égalisation 16.At the start of construction, the fasteners of the old R1 rails are removed. These old rails are moved apart using rail clips 14 and the old sleepers T1 are removed one by one by the picker 17 and conveyed by the member 17a to the intermediate conveyor 18 and, then, by the elevator 18a, to the storage conveyor 19. Behind the deposition installation, the ballast is equalized by the equalization blade 16.

Le portique 9 achemine les nouvelles traverses T2 depuis l'un des wagons de stockage 5 placé en tête du train, les décharge sur le transporteur 29 et prend ensuite les anciennes traverses T1 stockées sur le transporteur de stockage 19 pour les évacuer sur les wagons 5.The gantry crane 9 routes the new sleepers T2 from one of the storage wagons 5 placed at the head of the train, discharges them onto the transporter 29 and then takes the old sleepers T1 stored on the storage transporter 19 to evacuate them onto the wagons 5 .

Dès que les chenilles 12 s'engagent dans la zone de revouvellement, l'essieu avant 41 du chariot pose-rails 4 est abaissé, et ce chariot est découplé du wagon de travail 1. Ensuite, les nouvelles traverses T2 sont posées une à une au moyen de l'installation 22 à 24 supportée par le cadre 20.As soon as the tracks 12 engage in the covering area, the front axle 41 of the rail-laying carriage 4 is lowered, and this carriage is decoupled from the working wagon 1. Then, the new cross-members T2 are laid one by one by means of the installation 22 to 24 supported by the frame 20.

A cet effet, on fait guider le cadre pivotant 20 par un asservissement, lequel commande également le système de guidage des chenilles 12, le tout en fonction de la position de l'ancienne voie V1, par l'intermédiaire du palpuer 30. Ce nouveau système de guidage combiné comprend en outre: un mesureur de la valeur effective de l'angle α (figure 8) formé par la flèche fm de l'ancienne voie V1 et l'axe longitudinal A1 de l'unité de travail 1, un calculateur déterminant la valeur de consigne de l'angle α en fonction de la géométrie de la voie dans les courbes de raccordement et dans lequel sont introduites les valeurs de consigne connues de l'angle α pour des sections de courbes à courbure constante, et, le cas échéant, par exemple dans les courbes à rayon variable, un deuxième calculateur pour le calcul de l'angle de travail β formé par l'axe longitudinal A1 de l'unité de travail 1 et l'axe longitudinal A20 du cadre 20 de l'installation de pose des traverses en fonction de l'angle α, corrigé en fonction de la distance d'avancement de l'unité de travail 1 entre le point de mesure et le point de pose des traverses.To this end, the pivoting frame 20 is guided by a servo, which also controls the guide system for the tracks 12, all according to the position of the old track V1, by means of the feeler 30. This new combined guidance system further comprises: a meter for the effective value of the angle α (FIG. 8) formed by the arrow fm of the old track V1 and the longitudinal axis A1 of the working unit 1, a computer determining the setpoint value of the angle α as a function of the geometry of the track in the connection curves and into which the known setpoint values of the angle α are introduced for sections of curves with constant curvature, and, the if necessary, for example in curves with variable radius, a second computer for calculating the working angle β formed by the longitudinal axis A1 of the working unit 1 and the longitudinal axis A20 of the frame 20 of the installation for laying the sleepers in as a function of the angle α, corrected as a function of the advancement distance of the working unit 1 between the measurement point and the laying point of the sleepers.

Comme déjà mentionné, ce cadre pivotant 20 permet aussi, le cas échéant, un ripage des nouvelles tra­verses au moyen d'une commande à vérin 39.As already mentioned, this pivoting frame 20 also allows, if necessary, shifting of the new crosspieces by means of a jack control 39.

Dès que la machine est suffisamment avancée, les nouveaux rails R2, qui ont été préalablement posés de part et d'autre de la voie, sont centrés sur les nouvelles traversés T2 au moyen des pinces à rails 42 du chariot 4 qui est tracté par un câble 45, relié au wagon de travail 1. Ces nouveaux rails sont manipulés, comme les anciens, par les pinces à rails 28, à l'extrémité postérieure du cadre 20. Les anciens rails R1 guidés par les rouleaux de guidage 43 du chariot 4 sont posés derrière ce chariot 4 dans l'axe de la voie, à l'aide d'un lorry auxiliaire.As soon as the machine is sufficiently advanced, the new rails R2, which have been previously laid on either side of the track, are centered on the new crossings T2 by means of the rail clamps 42 of the carriage 4 which is towed by a cable 45, connected to the working wagon 1. These new rails are handled, like the old ones, by the rail clamps 28, at the rear end of the frame 20. The old rails R1 guided by the guide rollers 43 of the carriage 4 are placed behind this carriage 4 in the axis of the track, using an auxiliary lorry.

Pour la marche haut le pied, le boggie à chenilles 12 est centré sur l'ancienne voie et les essieux 11 sont abaissés. Le chariot pose-rails 4 est tracté à l'aide du câble 45. Il est ensuite accroché au wagon de travail 1, comme illustré à la figure 9 et, dans cette position de marche haut le pied, il sert de support du cadre pivotant 20 portant l'installation de pose de traverses, les pinces à rails 28 et la cabine 26 placée dans sa position élevée.For walking high, the tracked bogie 12 is centered on the old track and the axles 11 are lowered. The rail-laying trolley 4 is towed using the cable 45. It is then hooked to the working wagon 1, as illustrated in FIG. 9 and, in this running position, it serves as a support for the pivoting frame 20 carrying the installation for laying sleepers, the rail clamps 28 and the cabin 26 placed in its raised position.

Au lieu d'un câble 45, le chariot 4 peut aussi être tracté, en position de travail, par une barre téléscopique, pour que la distance de pose par rapport au wagon de travail 1 puisse être adaptée aux conditions de travail.Instead of a cable 45, the carriage 4 can also be towed, in the working position, by a telescopic bar, so that the laying distance relative to the working wagon 1 can be adapted to the working conditions.

Les figures 10 et 11 montrent une variante d'exécution en ce qui concerne l'unité de pose des nouveaux rails qui consiste, dans ce cas, en un wagon de chemin de fer 4′, monté sur deux essieux 40′, et muni également de pinces à rails 42′, des rouleaux de guidage 43′, d'une cabine mobile 44′ et d'un groupe 47′ pour l'entraî­nement des éléments de travail de ce wagon. Celui-ci est tracté, en position de travail, soit par un câble, soit par une barre télescopique, la cabine 44′ se trouvant en tête du wagon 4′. En position de marche haut le pied, ce wagon 4′ est attelé au wagon de travail 1 par une barre de liaison 46, comme montré à la figure 11, et porte dans cet état le cadre pivotant 20 avec l'installation pose-traverses, les pinces à rails 28 et la cabine 26, la cabine 44′ se trouvant à la queue.Figures 10 and 11 show an alternative embodiment with regard to the installation unit of the new rails which consists, in this case, of a railway wagon 4 ′, mounted on two axles 40 ′, and also provided rail clamps 42 ′, guide rollers 43 ′, a mobile cabin 44 ′ and a group 47 ′ for driving the working elements of this wagon. This is towed, in the working position, either by a cable or by a telescopic bar, the cabin 44 ′ being at the head of wagon 4 ′. In the walking position, this wagon 4 ′ is coupled to the working wagon 1 by a connecting bar 46, as shown in FIG. 11, and in this state carries the pivoting frame 20 with the installation of sleepers, the rail clamps 28 and the cabin 26, the cabin 44 ′ being at the tail.

L'invention n'est pas limitée aux formes d'exécution décrites mais peut présenter de nombreuses variantes.The invention is not limited to the embodiments described but can have many variants.
