Description

La présente invention concerne un train de renouvellement d'une voie de chemin de fer, comportant outre les wagons pour le transport des rails, des traverses et des fixations, au moins une rame de wagons de travail comportant un wagon de dépose, un wagon de dégarnissage, un wagon de pose, un wagon de tirefonnage et des moyens de transport des traverses ou travées anciennes et des traverses neuves.The present invention relates to a train for renewing a railway track, comprising, in addition to the wagons for transporting the rails, sleepers and fasteners, at least one train of working wagons comprising a deposition wagon, a stripping, a laying wagon, a wagon of drawing and means of transport for old sleepers or spans and new sleepers.

Le renouvellement d'une voie ferrée comprend, outre le remplacement des rails et des traverses, le renouvellement du ballast, car un vieux ballast, souillé de détritus et colmaté, ne possède plus les propriétés d'élasticité et de perméabilité requises. D'autre part, les apports successifs de gravier lors des opérations de rectification et de bourrage des traverses ont pour effet de rehausser la voie, ce qui présente de sérieux inconvénients principalement au passage des ouvrages d'art.The renewal of a railroad includes, in addition to the replacement of rails and sleepers, the renewal of the ballast, because an old ballast, soiled with detritus and clogged, no longer has the required elasticity and permeability properties. On the other hand, successive additions of gravel during operations rectification and stuffing of the sleepers have the effect of raising the track, which has serious drawbacks mainly to the passage of engineering structures.

Le même déposant est titulaire du brevet CH 583 822 qui concerne un procédé de renouvellement complet d'une voie ferrée, dans lequel le déroulement des opérations de dépose de l'ancienne voie, de dégarnissage-criblage du ballast et de pose de la nouvelle voie s'opère en un seul passage du train de renouvellement complet, prévu à cet effet. Le même brevet comporte également un train de renouvellement complet d'une voie de chemin de fer, comportant outre les wagons pour le transport des rails, des traverses et des fixations, au moins une rame de pose et de dépose équipée de portiques, et de wagons-cadres, telle qu'elle est connue par les brevets Nos 549 692 et 585 814 des mêmes titulaires. Dans ledit train de renouvellement sont incorporés des organes de dégarnissage et de transport du ballast vers une cribleuse installée sur un wagon placé en dehors de la zone de renouvellement.The same applicant is the holder of patent CH 583 822 which relates to a process for the complete renewal of a railway track, in which the procedure for removing the old track, stripping and screening the ballast and laying the new track operates in a single pass of the complete renewal train, provided for this purpose. The same patent also includes a train for the complete renewal of a railway track, comprising, in addition to the wagons for transporting the rails, sleepers and fasteners, at least one laying and removal train equipped with gantries, and frame wagons, as known from patents Nos. 549,692 and 585,814 of the same owners. In said renewal train are incorporated bodies for stripping and transporting the ballast to a screen installed on a wagon placed outside the renewal area.

Les exigences de plus en plus serrées dues au trafic toujours plus grand interdit l'usage de la deuxième voie pour les travaux, ce qui fait que ceux-ci doivent être exécutés toujours plus rapidement et avec des machines qui malgré leur largeur accrue doivent s'inscrire dans le gabarit autorisé.The increasingly tight requirements due to the ever increasing traffic prohibits the use of the second track for the works, which means that these must be executed always faster and with machines which despite their increased width must enter in the authorized template.

Le but de la présente invention est de proposer un train de renouvellement ou d'entretien qui s'inscrive encore mieux dans le gabarit de passage, tout en permettant l'augmentation de la largeur des wagons de travail et la réduction de leur empattement. L'invention telle qu'elle est caractérisée par les revendications, propose un train dans lequel au moins deux wagons de travail sont reliés entre eux par un cadre de liaison reposant sur un châssis équipé pour se mouvoir sur le ballast et/ou sur la banquette dégarnie, le châssis pouvant être abaissé plus ou moins par rapport au cadre de liaison de façon à soulever les essieux des wagons de travail dans la zone de travail, par le fait que chaque cadre de liaison relie deux wagons par l'intermédiaire d'articulations et de pièces de guidage qui servent à maintenir le châssis du wagon concerné dans sa position transversale par rapport à un des cadres de liaison.The object of the present invention is to provide a renewal or maintenance train which fits even better into the clearance gauge, while allowing the width of the working wagons to be increased and their wheelbase to be reduced. The invention as characterized by the claims, provides a train in which at least two working wagons are connected together by a connecting frame resting on a chassis equipped to move on the ballast and / or on the bench stripped, the chassis being able to be lowered more or less relative to the connecting frame so as to raise the axles of the working wagons in the working area, by the fact that each connecting frame connects two wagons by means of articulations and guide parts which serve to maintain the chassis of the wagon concerned in its transverse position relative to one of the connecting frames.

L'avantage obtenu consiste dans le fait que deux wagons de travail munis à leurs extrémités d'essieux ou de boggies peuvent s'articuler en trois éléments grâce à un cadre de liaison, très simple, reposant sur un châssis à chenilles. De cette façon on obtient que des wagons de travail relativement larges peuvent être maintenus dans le gabarit de passage, en particulier dans les courbes, et que pour la marche haut-le-pied chaque wagon peut rouler normalement sur ses propres essieux ou boggies.The advantage obtained consists in the fact that two working wagons provided at their ends with axles or bogies can be articulated in three elements thanks to a very simple connecting frame, resting on a chassis with tracks. In this way it is obtained that relatively wide working wagons can be kept in the clearance gauge, in particular in the curves, and that for the walk up-the-foot each wagon can roll normally on its own axles or boggies.

Le châssis à chenilles supportant le cadre de liaison sera avantageusement muni de moyens de propulsion et de guidage, de façon à permettre l'inscription optimale du train dans le gabarit de passage.The tracked chassis supporting the connection frame will advantageously be provided with propulsion and guiding means, so as to allow optimal registration of the train in the passage template.

Dans ce qui suit, l'invention est exposée plus en détail à l'aide de dessins représentant seulement un mode d'exécution.

  • Les figures 1 et 2 représentent schématiquement la disposition d'un train de renouvellement de la voie selon l'invention.
  • La figure 3 représente géométriquement l'inscription du train dans une courbe.
  • La figure 4 est une vue en élévation de la jonction d'un wagon de travail avec le cadre de liaison.
In the following, the invention is explained in more detail using drawings representing only one embodiment.
  • Figures 1 and 2 schematically represent the arrangement of a track renewal train according to the invention.
  • Figure 3 shows geometrically the registration of the train in a curve.
  • Figure 4 is an elevational view of the junction of a working wagon with the connecting frame.

Le train de renouvellement se compose de six éléments principaux, schématisés par les figures 1 et 2, soit une cribleuse, non représentée, un wagon de dépose 5, une dégarnisseuse 6, un wagon de pose 7, un wagon de tirefonnage et un portique avec poutre de transport, non représentés.The renewal train consists of six main elements, shown diagrammatically in FIGS. 1 and 2, namely a screener, not shown, a deposit wagon 5, a stripping machine 6, a laying wagon 7, a wagon for worming and a gantry with transport beam, not shown.

La cribleuse et le wagon de tirefonnage, non décrits ici, sont des wagons normaux à deux boggies. Le wagon de dépose 5, la dégarnisseuse 6 et le wagon de pose 7 constituent une rame articulée équipée de six boggies 12 à 17 et de deux châssis à chenilles 11 et 11'.The screening machine and the wagon, not described here, are normal wagons with two bogies. The deposit wagon 5, the stripper 6 and the laying wagon 7 constitute an articulated train fitted with six bogies 12 to 17 and two tracked chassis 11 and 11 '.

Lprs du travail, la cribleuse et le premier boggie 12 du wagon de dépose 5 roulent sur l'ancienne voie 1. La partie centrale du train s'appuie sur les deux châssis à chenilles 11 et 11' qui roulent respectivement sur le ballast et sur la banquette excavée, ou sur le ballast criblé. Le boggie arrière 17 du wagon de pose 7 ainsi que le wagon de tirefonnage roulent sur la nouvelle voie 4.After work, the screening machine and the first bogie 12 of the delivery wagon 5 roll on the old track 1. The central part of the train rests on the two track chassis 11 and 11 'which roll respectively on the ballast and on the excavated bench, or on the screened ballast. The rear bogie 17 of the laying wagon 7 as well as the dowelling wagon roll on the new track 4.

Les wagons de travail 5, 6, 7 sont reliés entre eux par des cadres de liaison 8, 8' reposant sur les châssis à chenilles 11, 11'. Chaque cadre de liaison 8, 8' relie deux wagons par l'intermédiaire d'articulations 9 à cardan. Des pièces de guidages 10 servent à maintenir le châssis du wagon concerné dans sa position transversale par rapport au cadre de liaison 8 et, des butées hydrauliques 42 maintiennent le cadre de liaison concerné dans une position longitudinale déterminée par rapport au châssis du wagon.The working wagons 5, 6, 7 are interconnected by connecting frames 8, 8 'resting on the tracked chassis 11, 11'. Each connecting frame 8, 8 ′ connects two wagons by means of cardan joints 9. Guide pieces 10 serve to maintain the chassis of the wagon concerned in its transverse position relative to the connection frame 8 and, hydraulic stops 42 maintain the connection frame concerned in a determined longitudinal position relative to the chassis of the wagon.

Pendant le travail, les deux châssis à chenilles 11, 11' avec les cadres de liaison 8, 8' sont guidés comme schématisé par la figure 3. Les points géométriques A, B, C, D, E, F et b, c, d, e sont reportés sur la figure 1.During work, the two tracked chassis 11, 11 'with the connecting frames 8, 8' are guided as shown diagrammatically in FIG. 3. The geometric points A, B, C, D, E, F and b, c, d, e are shown in FIG. 1.

Les deux châssis à chenilles 11, 11' sont montés sur des plaques tournantes. Ils sont abaissés, levés et guidés par des vérins hydrauliques. Un entraînement hydrostatique permet une vitesse de travail variable. Le guidage des chenilles peut être effectué de trois manières :

  • -soit par des palpeurs montés sur des châssis à chenilles, utilisant la voie parallèle comme référence,
  • -'soit par dispositif asservi à la position de la voie ancienne 1 mesurée par des palpeurs de rails, montés soit sur la cribleuse en avant de la zone de travail, soit sur le wagon 7 de pose des traverses, ainsi que par un système de mesure des angles α,β,γ,δ entre les cadres de liaisons 8, 8' et les wagons de travail adjacents (fig. 3),
  • - soit par une commande manuelle.
The two tracked chassis 11, 11 'are mounted on turntables. They are lowered, raised and guided by hydraulic cylinders. A hydrostatic drive allows a variable working speed. There are three ways to guide the tracks:
  • -or by probes mounted on crawler chassis, using the parallel track as a reference,
  • - either by device controlled by the position of the old track 1 measured by rail probes, mounted either on the screening machine in front of the work area, or on the wagon 7 for laying the sleepers, as well as by a system of measurement of the angles α, β, γ, δ between the connection frames 8, 8 'and the adjacent working wagons (fig. 3),
  • - either by manual control.

Les commandes automatiques sont conçues de telle manière que les deux châssis à chenilles 11, 11' suivent le tracé de l'ancienne voie ou d'un tracé parallèle si l'on veut modifier les distances entre les voies.The automatic controls are designed in such a way that the two tracked chassis 11, 11 ′ follow the layout of the old track or a parallel layout if the distances between the tracks are to be modified.

Le wagon de dépose 5, figures 1 à 4, s'appuie à l'avant sur un boggie 12 et à l'arrière, par l'intermédiaire d'un cadre articulé 8 sur le châssis à chenilles 11. Dans le wagon sont montés, les transporteurs 18 pour le matériel excavé et, au-dessus, les transporteurs 19 pour le ballast récupéré. La dépose et le transport des anciennes traverses 32 s'effectuent à l'aide d'une piocheuse hydraulique 20, de transporteurs à chaînes 21, d'un élévateur non représenté et d'un transporteur 23 qui transporte les anciennes traverses sur des wagons de chargement. La dégarnisseuse 6 (fig. 1) est équipée de deux boggies 14 et 15, d'une excavatrice 30, d'un doseur à ballast et d'éléments de transport pour le ballast, les traverses ou les travées. Ce wagon est relié en tête au wagon de dépose 5 et en queue au wagon de pose 7, chaque fois par l'intermédiaire d'un cadre de liaison articulé 8, 8' muni d'un châssis à chenilles 11, 11'.The deposit wagon 5, FIGS. 1 to 4, is supported at the front on a bogie 12 and at the rear, by means of an articulated frame 8 on the tracked chassis 11. In the wagon are mounted , the conveyors 18 for the excavated material and, above, the conveyors 19 for the recovered ballast. Removal and transport of the old sleepers 32 is carried out using a hydraulic picker 20, chain conveyors 21, an elevator not shown and a conveyor 23 which transports the old sleepers on loading wagons. The stripper 6 (fig. 1) is equipped with two bogies 14 and 15, an excavator 30, a ballast metering device and transport elements for the ballast, the sleepers or the spans. This wagon is connected at the head to the deposition wagon 5 and at the tail to the laying wagon 7, each time by means of an articulated connection frame 8, 8 'provided with a tracked chassis 11, 11'.

Le wagon de pose 7 muni de deux boggies 16 et 17 est équipé des organes de pose de traverses avec les éléments de transport, des organes de pose des rails et du distributeur à ballast. Pendant le travail, ce wagon s'appuie en avant sur le cadre de liaison 8' à chenilles et en arrière sur le boggie 17 qui roule sur la nouvelle voie 4. Dans la partie arrière du wagon de pose sont montés les organes de pose de rails neufs comportant des pinces à galets.The laying wagon 7 provided with two bogies 16 and 17 is equipped with members for laying sleepers with the transport elements, members for laying the rails and the ballast distributor. During work, this wagon rests forward on the 8 'tracked connecting frame and back on the bogie 17 which rolls on the new track 4. In the rear part of the laying wagon are mounted the laying members of new rails with roller clamps.

La description qui précède concernait, à titre d'exemple, l'application de l'invention à un train de renouvellement de la voie. Bien entendu, l'invention s'applique également à tout train d'entretien de la voie.The foregoing description relates, by way of example, to the application of the invention to a track renewal train. Of course, the invention also applies to any train for maintaining the track.
