Description

"Système de transport, de chargement et de déchargement de rails d'une voie ferroviaire"  "Rail transport, loading and unloading system for a railway track"
[0001 ] L'invention concerne un système de transport, de chargement et de déchargement de rails d'une voie ferroviaire, du type comprenant au moins un wagon de transport des rails disposés sur celui-ci, parallèlement à l'axe du wagon, et une pluralité de potences de chargement et de déchargement des rails, qui comportent un agencement de chariots de transport des rails entre le wagon et les côtés de la voie ferroviaire sur laquelle circule le wagon. The invention relates to a system for transporting, loading and unloading rails of a railway track, of the type comprising at least one rail transport car arranged thereon, parallel to the axis of the car, and a plurality of rails for loading and unloading the rails, which comprise an arrangement of trolleys for transporting the rails between the wagon and the sides of the railway track on which the wagon is traveling.
[0002] Des systèmes de ce type, qui sont connus, présentent l'inconvénient majeur qu'ils ne permettent de déposer et de recharger les rails qu'au-delà de la largeur du wagon de transport de ceux-ci. Les rails peuvent ainsi être posées sur une banquette de ballaste instable ou du côté de la voie, où leur position ne garantit pas la sécurité souhaitée, car souvent le gabarit de circulation ferroviaire est dépassé lors des opérations de préhension de pose des rails. [0003] L'invention a pour but de pallier cet inconvénient. Systems of this type, which are known, have the major disadvantage that they allow to deposit and reload the rails beyond the width of the transport car thereof. The rails can thus be placed on an unstable ballast bench or on the side of the track, where their position does not guarantee the desired safety, because often the rail circulation gauge is exceeded during the gripping operations of laying rails. The invention aims to overcome this disadvantage.
[0004] Pour atteindre ce but, le système selon l'invention est caractérisé en ce que l'agencement de saisie et de transport des rails est adapté pour permettre une pose des rails sur les têtes des traverses de la voie ferroviaire sur laquelle se déplace le wagon de transport. [0005] Selon une caractéristique avantageuse de l'invention, le est caractérisé en ce que chaque potence 5 comporte un mât 15 monté verticalement sur le wagon 1 et en ce que l'agencement de chargement et de déchargement 1 1 des rails comprend un dispositif de chariots 17, 19 déplaçable sur le mât, verticalement et horizontalement, entre une position de saisie d'un rail 3 et une position de pose du rail sur les têtes de traverse 13 précitées. [0006] Selon une autre caractéristique, le système est caractérisé en ce que le dispositif de chariots comprend un chariot 17 qui est déplaçable sur le mât 15 de la potence 5 entre une position de saisie d'un rail et une position de pose du rail sur les têtes de traverse 13 et au moins un chariot 19 qui est déplaçable perpendiculairement à l'axe longitudinal du wagon entre une position de saisie d'un rail et une position de pose de ce rail. [0007] Selon encore une autre caractéristique de l'invention, le système est caractérisé en ce que le chariot déplaçable horizontalement 19 est déplaçable sur une poutre horizontale 21 qui est montée sur le chariot verticalement mobile 17 et s'étend perpendiculairement à l'axe longitudinal du wagon. [0008] Selon encore une autre caractéristique de l'invention le système est caractérisé en ce que l'agencement de chargement et de déchargement 1 1 de rails comporte deux chariots 19 déplaçables horizontalement chacun sur une poutre 21 . To achieve this goal, the system according to the invention is characterized in that the gripping and transport arrangement of the rails is adapted to allow a laying of the rails on the heads of the rails of the railway track on which moves the transport car. According to an advantageous characteristic of the invention, it is characterized in that each bracket 5 comprises a mast 15 mounted vertically on the car 1 and in that the arrangement of loading and unloading 1 1 of the rails comprises a device of carriages 17, 19 movable on the mast, vertically and horizontally, between a gripping position of a rail 3 and a laying position of the rail on the crossheads 13 mentioned above. According to another feature, the system is characterized in that the trolley device comprises a carriage 17 which is movable on the mast 15 of the bracket 5 between a gripping position of a rail and a rail laying position on the crossheads 13 and at least one carriage 19 which is movable perpendicularly to the longitudinal axis of the car between a gripping position of a rail and a laying position of the rail. According to yet another characteristic of the invention, the system is characterized in that the horizontally displaceable carriage 19 is displaceable on a horizontal beam 21 which is mounted on the vertically movable carriage 17 and extends perpendicular to the axis. longitudinal of the wagon. According to yet another feature of the invention the system is characterized in that the arrangement of loading and unloading 1 1 of rails comprises two carriages 19 horizontally movable each on a beam 21.
[0009] Selon encore une autre caractéristique de l'invention le système est caractérisé en ce que chaque chariot horizontalement déplaçable 19 porte un dispositif 25 de saisie et de pose de rails. According to yet another characteristic of the invention the system is characterized in that each horizontally displaceable carriage 19 carries a device 25 for gripping and laying rails.
[0010] Selon encore une autre caractéristique de l'invention le système est caractérisé en ce qu'un dispositif 25 de saisie et de pose de rails comporte une tige 25 fixée verticalement sous le chariot et une bielle 28 qui porte à son extrémité libre un dispositif de pinces de saisie de rails 31 , qui est monté pivotant dans un plan vertical perpendiculaire à l'axe longitudinal du wagon entre une position en alignement avec la tige 27 et une position inclinée de pose de rails 3 sur les têtes de traverse 13, dans laquelle elle est inclinée en direction de l'axe longitudinal du wagon. According to yet another feature of the invention the system is characterized in that a device 25 for gripping and installing rails comprises a rod 25 fixed vertically under the carriage and a connecting rod 28 which carries at its free end a rail grab gripper device 31, which is pivotally mounted in a vertical plane perpendicular to the longitudinal axis of the car between a position in alignment with the rod 27 and an inclined rail laying position 3 on the crossheads 13, in which it is inclined towards the longitudinal axis of the wagon.
[001 1 ] Selon encore une autre caractéristique de l'invention le système est caractérisé en ce que, dans sa position de pose des rails 3 sur les têtes de traverse 13, l'agencement de chargement et de déchargement reste à l'intérieur du gabarie de circulation ferroviaire. According to yet another characteristic of the invention, the system is characterized in that, in its position of laying the rails 3 on the crossheads 13, the loading and unloading arrangement remains within the rail traffic gage.
[0012] L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels : - La figure 1 est une vue en perspective d'un système de transport de chargement et de déchargement de rails d'une voie ferroviaire, selon l'invention ; The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows with reference to the accompanying drawings given solely by way of example illustrating a Embodiment of the invention and in which: - Figure 1 is a perspective view of a rail loading and unloading transport system of a railway track, according to the invention;
- la figure 2 est une vue à plus grande échelle du détail indiqué en II sur la figure 1 ; FIG. 2 is an enlarged view of the detail indicated at II in FIG. 1;
- les figures 3 à 5 sont des vues en direction de l'axe du wagon de transport, du système selon l'invention, et illustrent trois phases différentes du fonctionnement du système, et - la figure 6 est une vue à plus grande échelle de la partie VI de la figure 4. [0013] L'invention sera décrite ci-après, à titre d'exemple non limitatif, dans sa version illustrée à la figure 1. Dans cet exemple, le système de transport, de chargement et de déchargement de rails d'une voie ferroviaire ne comporte qu'un wagon, mais pourrait en comporter un plus grand nombre. Comme on le voit sur la figure, le wagon noté 1 de transport de rails 3 disposés sur le platelage du wagon en étant orienté parallèlement à l'axe longitudinal du wagon, comporte deux potences 5 de chargement et de déchargement des rails 3. La voie ferroviaire sur laquelle circule le wagon 1 porte la référence 7 et comporte des rails 8 reposant sur des traverses 9. FIGS. 3 to 5 are views in the direction of the axis of the transport car, of the system according to the invention, and illustrate three different phases of the operation of the system, and FIG. 6 is a view on a larger scale of Part VI of Figure 4. The invention will be described below, by way of non-limiting example, in its version illustrated in Figure 1. In this example, the system for transporting, loading and unloading rails of a railway track has only one car, but could have a larger number. As can be seen in the figure, the wagon noted 1 of rail transport 3 disposed on the decking of the wagon being oriented parallel to the longitudinal axis of the wagon, has two brackets 5 loading and unloading rails 3. The track rail on which runs the wagon 1 carries the reference 7 and comprises rails 8 resting on sleepers 9.
[0014] Chaque potence est équipée d'un agencement 1 1 de transport des rails 3 entre leur position de stockage sur le wagon 1 et une position de pose soit au côté droit soit au côté gauche de la voie ferroviaire 7, plus précisément sur les extrémités 13 de la voie ferroviaire 7. Each bracket is equipped with an arrangement 1 1 for transporting the rails 3 between their storage position on the car 1 and a laying position is on the right side or the left side of the rail track 7, specifically on the ends 13 of the railway track 7.
[0015] Comme le montre plus clairement la figure 2, une potence 5 comporte un mât 15 monté verticalement sur le platelage du wagon et l'agencement de chargement et de déchargement des rails 1 1 comprend un chariot 17 qui est monté sur le mât 15, axialement mobile sur celui-ci, entre une position basse de saisie des rails et une position haute de transport des rails perpendiculairement à l'axe du wagon, et deux chariots 19 qui sont susceptibles de se déplacer horizontalement, l'un vers la gauche et l'autre vers la droite du wagon, pour effectuer l'acheminement horizontal précité des rails. A cette fin, chaque rail est monté coulissant sur une poutre 21 qui est montée sur le chariot vertical 17 et s'étend horizontalement et perpendiculairement à l'axe longitudinal du wagon. Le déplacement des chariots le long de leur poutre 21 est réalisé à l'aide d'un vérin hydraulique dont le corps est désigné par la référence 23 et qui s'étend parallèlement à la poutre en étant fixé sur celle-ci. [0016] Chaque chariot porte un dispositif 25 de saisie et de pose de rails. Dans son mode de réalisation représenté et donné uniquement à titre d'exemple non limitatif, ce dispositif 25 montré à plus grande échelle à la figure 6 comprend une tige 27 qui est montée fixe sur le chariot 19 de façon à s'étendre verticalement vers le bas, et une bielle 29 qui s'étend dans l'axe du bras 27, mais dont l'extrémité supérieure est montée pivotante autour d'un axe 29 sur l'extrémité inférieure de la tige 27, tandis que son extrémité inférieure porte un dispositif de pinces de saisie de rails, noté 31. La bielle 28 est susceptible de pivoter dans un plan vertical perpendiculaire à l'axe longitudinal du wagon, son axe de pivotement 29 étant orienté parallèlement à cet axe. [0017] Le dispositif de commande du pivotement de la bielle 28, noté 33, comprend un câble 35 dont une extrémité est fixée en 36 au chariot 19 et qui passe autour d'une première poulie 37 montée sur le chariot et une deuxième poulie de renvoi 38 au niveau de l'extrémité inférieure de la tige 27 à l'extrémité inférieure de la bielle 28, plus précisément à l'extrémité libre à laquelle il est fixé en 39, d'un bras 40 solidaire à son autre extrémité à la bielle et orienté obliquement par rapport à l'axe de cette dernière. As shown more clearly in Figure 2, a bracket 5 comprises a mast 15 mounted vertically on the decking of the car and the arrangement of loading and unloading rails 1 1 comprises a carriage 17 which is mounted on the mast 15 axially movable on it, between a low position for gripping the rails and a high position for transporting the rails perpendicular to the axis of the wagon, and two carriages 19 which are capable of moving horizontally, one to the left and the other to the right of the wagon, to carry out the aforementioned horizontal routing of the rails. To this end, each rail is slidably mounted on a beam 21 which is mounted on the vertical carriage 17 and extends horizontally and perpendicularly to the longitudinal axis of the wagon. The displacement of the carriages along their beam 21 is achieved by means of a hydraulic cylinder whose body is designated by the reference 23 and which extends parallel to the beam being fixed thereto. Each carriage carries a device 25 for gripping and laying rails. In its embodiment shown and given solely by way of nonlimiting example, this device 25 shown on a larger scale in FIG. 6 comprises a rod 27 which is fixedly mounted on the carriage 19 so as to extend vertically towards the bottom, and a rod 29 which extends in the axis of the arm 27, but whose upper end is pivotally mounted about an axis 29 on the lower end of the rod 27, while its lower end carries a 31. The rod 28 is pivotable in a vertical plane perpendicular to the longitudinal axis of the wagon, its pivot axis 29 being oriented parallel to this axis. The device for controlling the pivoting of the rod 28, noted 33, comprises a cable 35, one end of which is fixed at 36 to the carriage 19 and which passes around a first pulley 37 mounted on the carriage and a second pulley. 38 at the lower end of the rod 27 at the lower end of the rod 28, more precisely at the free end to which it is fixed at 39, an arm 40 secured at its other end to the connecting rod and oriented obliquely to the axis of the latter.
[0018] Le pivotement de la bielle autour de l'axe 29, en direction de l'axe longitudinale du wagon est obtenu grâce au fait que la poulie 37 associée au chariot 19 est montée sur l'extrémité de la tige de piston d'un vérin hydraulique 41 qui est monté verticalement sur le chariot 19. Plus précisément, c'est l'axe horizontal 43 de la poulie qui est fixée sur la tige de piston. The pivoting of the connecting rod about the axis 29, in the direction of the longitudinal axis of the car is obtained thanks to the fact that the pulley 37 associated with the carriage 19 is mounted on the end of the piston rod of a hydraulic cylinder 41 which is mounted vertically on the carriage 19. More specifically, it is the horizontal axis 43 of the pulley which is fixed on the piston rod.
[0019] Bien entendu, le dispositif de pivotement de la bielle 28 peut être réalisé de toute autre manière appropriée connue, par exemple à l'aide d'un vérin hydraulique monté entre la tige 27 et la bielle 28. [0020] Comme il a été expliqué plus haut, les chariots 19 qui sont déplaçables horizontalement sont montés sur le chariot 17 qui coulisse sur le mât 15 de la potence, par l'intermédiaire des poutres horizontales 21. Ce coulissement du chariot 17 est obtenu grâce à un dispositif 45 qui est formé par deux bielles 46 et 47, qui sont articulées l'une à l'autre par une de leurs extrémités, en 48, tandis que l'extrémité inférieure de la bielle 46 est articulée à une plaque de support du mât 15, en 49, et l'extrémité libre de la bielle 47 est articulée en 50 à une chape 51 solidaire du chariot 17. Pour obtenir le coulissement du chariot 17, on utilise un vérin hydraulique 52 qui est monté entre les deux bielles 46 et 47, de façon à provoquer un repliage ou un déploiement du dispositif de bielles 45. Pour faire descendre le chariot, le vérin 52 fait pivoter les deux bielles l'une vers l'autre. Pour un coulissement du chariot 17 vers le haut sur le mât 15, le vérin provoque le déploiement du dispositif de bielles. Of course, the pivoting device of the rod 28 may be made in any other appropriate manner known, for example using a hydraulic cylinder mounted between the rod 27 and the connecting rod 28. [0020] As has been explained above, the carriages 19 which are movable horizontally are mounted on the carriage 17 which slides on the mast 15 of the bracket, through the horizontal beams 21. This sliding of the carriage 17 is obtained through a device 45 which is formed by two connecting rods 46 and 47, which are articulated to one another by one of their ends, at 48, while the lower end of the connecting rod 46 is articulated to a support plate of the mast 15, at 49, and the free end of the rod 47 is articulated at 50 to a yoke 51 secured to the carriage 17. To obtain the sliding of the carriage 17, a hydraulic cylinder 52 is used which is mounted between the two links 46 and 47, so as to cause a fallback or deployment of the connecting rod device 45. To lower the carriage, the cylinder 52 rotates the two rods towards one another. For sliding of the carriage 17 upwards on the mast 15, the jack causes the deployment of the connecting rod device.
[0021 ] On décrit ci-après le fonctionnement du système qui vient d'être décrit, en se reportant notamment aux figures 3 à 5. The operation of the system which has just been described is described below, with particular reference to FIGS. 3 to 5.
[0022] La figure 3 montre le système au début d'un processus de déchargement des rails 3. On constate que le dispositif de pince 31 de chaque chariot horizontal 19 vient de saisir un rail 3. Le chariot vertical 17 se trouve en haut du mât 15 de la potence. Chaque chariot horizontal 19 est encore dans sa position de la saisie du rail, proche du mât. La figure 4 montre les chariots 19 dans leurs positions aux extrémités libres de leurs poutres 21 , après s'être déplacés le long de celle-ci. Le chariot vertical est toujours dans sa position haute. On constate que les chariots 19, avec leurs dispositifs 25 de saisie et de pose des rails sont toujours à l'intérieur du gabarie de circulation ferroviaire indiqué par la ligne 55. Dans cette position les rails 3 saisies par les dispositifs de pince 31 sont abaissés en le faisant passer près des bords latéraux du wagon, mais toujours à l'intérieur du gabarie, en faisant coulisser le chariot 17 vers le bas, le long de son mât 15, grâce au pliage du dispositif de bielles 45 à l'aide de leur vérin d'actionnement 52. Figure 3 shows the system at the beginning of a process of unloading the rails 3. It is found that the gripper device 31 of each horizontal carriage 19 has just grabbed a rail 3. The vertical carriage 17 is at the top of the mast 15 of the gallows. Each horizontal carriage 19 is still in its position of seizing the rail, close to the mast. The Figure 4 shows the carriages 19 in their positions at the free ends of their beams 21, after having moved along it. The vertical carriage is always in its high position. It can be seen that the carriages 19, with their devices 25 for gripping and laying the rails, are always inside the rail traffic jig indicated by the line 55. In this position, the rails 3 gripped by the gripper devices 31 are lowered. by passing it near the side edges of the wagon, but still inside the jig, by sliding the carriage 17 downwards along its mast 15, thanks to the folding of the connecting rod device 45 with the aid of their actuating cylinder 52.
[0023] Lorsque les rails se trouvent en-dessous de la plateforme du wagon, près de leur position de pose, on actionne le vérin 41 des chariots 19 pour qu'ils provoquent un mouvement vers le haut des poulies 37, d'une faible distance, de façon à provoquer le pivotement des bielles 28, par l'intermédiaire des câbles 35 en direction de l'axe du wagon, c'est-à-dire en direction de la flèche F, comme le montre la figure 5. Ce pivotement a pour but de poser chaque rail 3 sur les têtes 13 des traverses 9 de la voie ferroviaire, sur un côté de celle-ci. Ainsi les rails déchargés sont stockés provisoirement sur les têtes des traverses en prévision imminente du chantier de remplacement des rails usés sur la voie existante, tout en évitant de sortir du gabarie, et en toute sécurité et en garantissant la stabilité des rails reposant sur les têtes de traverse. When the rails are below the platform of the wagon, near their position of installation, it actuates the cylinder 41 of the carriages 19 so that they cause an upward movement of the pulleys 37, a low distance, so as to cause the pivoting rods 28, through the cables 35 in the direction of the axis of the wagon, that is to say in the direction of the arrow F, as shown in Figure 5. This pivoting is intended to put each rail 3 on the heads 13 of the sleepers 9 of the railway track, on one side thereof. Thus the unloaded rails are temporarily stored on the heads of the sleepers in anticipation of the replacement of worn rails on the existing track, while avoiding leaving the template, and safely and ensuring the stability of the rails resting on the heads crossing.
[0024] Bien entendu, de multiples modifications peuvent être apportés au système tel que décrit et représenté, sans sortir du cadre de l'invention. Ainsi, les moyens de commande du déplacement du chariot vertical 17 et des chariots horizontaux 19 peuvent être réalisés de toute autre manière appropriée. Ceci est valable notamment pour le dispositif de bielles repliable et déployable pour le coulissement du chariot 17 sur le mât 15 d'une potence et pour le dispositif de saisie et de pose 25 des rails. Of course, multiple modifications can be made to the system as described and shown, without departing from the scope of the invention. Thus, the means for controlling the movement of the vertical carriage 17 and the horizontal carriages 19 may be made in any other appropriate manner. This is particularly valid for the folding rod device and deployable for sliding of the carriage 17 on the mast 15 of a bracket and the device for gripping and laying 25 rails.
