Description

Domaine techniqueTechnical area

L'invention concerne l'appui et le guidage d'un câble tracteur de véhicule d'une installation de transport par câble, et plus particulièrement l'appui et le guidage d'un câble tracteur aérien.The invention relates to the support and guidance of a vehicle traction cable of a cable transport installation, and more particularly the support and guidance of an aerial traction cable.

Etat de la techniqueState of the art

Actuellement, les installations de transport par câble tracteur de véhicule sont équipées de dispositifs d'appui et de guidage, tels que des balanciers, pour maintenir et guider les câbles tracteurs en mouvement entre les gares d'embarquement et de débarquement des passagers. Généralement, les balanciers sont portés par des pylônes et sont équipés de galets rotatifs sur lesquels le câble tracteur est en appui. Les galets sont montés à rotation libre sur des poutres articulées pour maintenir le câble tracteur en appui sur le pylône lors des variations de flèche du câble dues au poids du véhicule et au passage de la pince du véhicule sur les galets.Currently, vehicle traction cable transport installations are equipped with support and guide devices, such as pendulums, to maintain and guide the traction cables in motion between the passenger embarkation and disembarkation stations. Generally, the pendulums are carried by pylons and are equipped with rotating rollers on which the traction cable rests. The rollers are mounted in free rotation on articulated beams to keep the traction cable resting on the pylon during variations in the deflection of the cable due to the weight of the vehicle and the passage of the clamp of the vehicle over the rollers.

On peut citer la demande de brevet français FR2920385 , déposée au nom de la demanderesse, qui divulgue un dispositif mécanique de réglage d'un balancier d'appui et de guidage d'un câble aérien d'une installation de remontée mécanique. Le balancier comporte des galets de guidage du câble montés à rotation sur un châssis-porteur selon des axes de rotation parallèles échelonnés le long du châssis-porteur.We can cite the French patent application FR2920385 , filed in the name of the applicant, which discloses a mechanical device for adjusting a support beam and guiding an overhead cable of a mechanical lift installation. The rocker arm comprises cable guide rollers rotatably mounted on a carrier frame along parallel axes of rotation staggered along the carrier frame.

De manière générale, on utilise un axe, qui est une pièce allongée, pour articuler en rotation ou en pivotement un élément mobile par rapport à un support, mobile ou fixe, l'axe étant monté fixe sur le support. L'axe de rotation est une pièce importante du balancier et il peut être soumis à des défaillances, comme des usures ou dans des situations exceptionnelles une rupture. Sa rupture entraînerait la chute de tous les éléments du balancier.In general, a shaft, which is an elongated part, is used to articulate in rotation or in pivoting a movable element with respect to a support, mobile or fixed, the shaft being fixedly mounted on the support. The axis of rotation is a part important part of the balance and it can be subject to failures, such as wear or, in exceptional situations, breakage. Its breakage would lead to the fall of all the elements of the pendulum.

Les balanciers sont des éléments complexes et sont donc régulièrement soumis à des inspections pour contrôler leur état. En particulier, il peut être nécessaire de démonter un balancier pour contrôler avec précision les pièces éventuellement usées qui doivent être remplacées, notamment les axes de rotation. Le démontage d'un balancier est une opération longue et délicate.The balance wheels are complex elements and are therefore regularly inspected to check their condition. In particular, it may be necessary to disassemble a balance beam to accurately check any worn parts that must be replaced, in particular the axes of rotation. Dismantling a balance wheel is a long and delicate operation.

On peut en outre citer la demande de brevet français FR 3074467 , déposée au nom de la demanderesse, qui divulgue un dispositif d'appui et de guidage d'un câble tracteur, comprenant un axe creux pour articuler une poutre par rapport à une structure porteuse du dispositif d'appui et de guidage, et pour permettre une inspection de l'intérieur de l'axe sans avoir à démonter le dispositif d'appui et de guidage. Mais en cas de rupture de l'axe, la poutre articulée n'est plus maintenue par la structure porteuse et elle peut tomber en entraînant la chute de tous les éléments que la poutre supporte. La demande de brevet français FR2838697 divulgue un dispositif d'appui et de guidage d'un câble tracteur comprenant des butées arrangées sur une première poutre pour limiter la rotation d'une deuxième poutre.We can also cite the French patent application EN 3074467 , filed in the name of the applicant, which discloses a device for supporting and guiding a traction cable, comprising a hollow axis for articulating a beam with respect to a supporting structure of the supporting and guiding device, and for allowing an inspection of the inside of the shaft without having to disassemble the support and guide device. But in case of breakage of the axis, the articulated beam is no longer held by the load-bearing structure and it can fall causing the fall of all the elements that the beam supports. French patent application FR2838697 discloses a device for supporting and guiding a traction cable comprising stops arranged on a first beam to limit the rotation of a second beam.

Exposé de l'inventionDisclosure of Invention

Un objet de l'invention consiste à pallier ces inconvénients, et plus particulièrement à fournir des moyens d'appui et de guidage qui évitent d'avoir à démonter les éléments d'un dispositif d'appui et de guidage pour inspecter l'état d'usure des axes de rotation du dispositif.An object of the invention is to overcome these drawbacks, and more particularly to provide support and guide means which avoid having to disassemble the elements of a support and guide device to inspect the state of wear of the axes of rotation of the device.

Un autre objet consiste à fournir un moyen pour sécuriser l'appui et le guidage d'un câble tracteur d'une installation de transport de véhicule.Another object consists in providing a means for securing the support and the guidance of a traction cable of a vehicle transport installation.

Selon un aspect de l'invention, il est proposé un dispositif d'appui et de guidage pour un câble tracteur d'une installation de transport de véhicule par câble, comprenant un galet configuré pour l'appui et le guidage du câble tracteur, une première poutre munie d'un axe principal, une deuxième poutre supportant le galet et montée mobile en pivotement autour de l'axe principal.According to one aspect of the invention, there is proposed a support and guide device for a traction cable of a vehicle transport installation by cable, comprising a roller configured for supporting and guiding the traction cable, a first beam provided with a main axis, a second beam supporting the roller and mounted so as to pivot around the main axis.

Le dispositif comporte au moins un élément de rattrapage monté sur la première poutre et configuré pour rattraper la deuxième poutre dans un état anormal de fonctionnement correspondant à une défaillance de l'axe principal, et au moins un élément de coopération monté sur la deuxième poutre à distance dudit au moins un élément de rattrapage dans un état normal de fonctionnement où la deuxième poutre pivote autour de l'axe principal, ledit au moins un élément de coopération étant configuré pour être en contact avec ledit au moins un élément de rattrapage dans l'état anormal de fonctionnement.The device comprises at least one take-up element mounted on the first beam and configured to take up the second beam in an abnormal operating state corresponding to a failure of the main axis, and at least one cooperation element mounted on the second beam to distance of said at least one take-up element in a normal operating state where the second beam pivots around the main axis, said at least one cooperating element being configured to be in contact with said at least one take-up element in the abnormal state of operation.

Ainsi, on fournit un dispositif d'appui et de guidage équipé d'éléments configurés pour rattraper une poutre mobile en pivotement en cas d'une défaillance de l'axe principal. En d'autres termes, les éléments du dispositif empêchent la poutre mobile de tomber dans le cas exceptionnel d'une rupture de l'axe principal. De tels éléments permettent de limiter les inspections de l'axe principal pour contrôler son état de fonctionnement. Les éléments limitent ainsi les démontages du balancier.Thus, there is provided a support and guide device equipped with elements configured to catch up with a movable beam in pivoting in the event of a failure of the main axis. In other words, the elements of the device prevent the mobile beam from falling in the exceptional case of a breakage of the main axis. Such elements make it possible to limit the inspections of the main axis to check its operating condition. The elements thus limit the dismantling of the balance wheel.

Ledit au moins un élément de rattrapage et ledit au moins un élément de coopération peuvent être conformés pour permettre un pivotement de la deuxième poutre dans l'état anormal de fonctionnement.Said at least one take-up element and said at least one cooperation element can be shaped to allow pivoting of the second beam in the abnormal operating state.

Avantageusement, on fournit un dispositif qui permet un pivotement des poutres même en cas de rupture d'un axe principal. On peut alors exploiter l'installation un certain temps avant d'effectuer les opérations de réparation et de changement des parties endommagées du balancier.Advantageously, a device is provided which allows pivoting of the beams even in the event of breakage of a main axis.

Description détailléedetailed description

Sur les figures 1 à 18, on a représenté un dispositif d'appui et de guidage 1 pour un câble tracteur 2 d'une installation de transport de véhicule par câble. Le ou les véhicules et l'installation ne sont pas représentés à des fins de simplification.On the figures 1 to 18 , there is shown a support and guide device 1 for a traction cable 2 of a vehicle transport installation by cable. The vehicle or vehicles and the installation are not represented for the purpose of simplification.

De manière générale, le dispositif 1 comprend au moins un galet 3 et au moins deux poutres 4 à 14. Le dispositif 1 est destiné à supporter le câble tracteur 2, plus particulièrement le dispositif 1 fournit un appui et un guidage au câble 2. Le câble tracteur 2 repose sur les galets 3 qui sont configurés pour l'appui et le guidage du câble tracteur 2. Les poutres 4 à 14 comprennent, chacune, au moins un axe 15 à 25. En outre, l'installation comprend une structure porteuse 27 fixe, et les poutres 4 à 14 sont articulées par rapport à la structure porteuse 27. Un premier ensemble d'axes 15 à 23 et 25, notés axes principaux, permet d'articuler les poutres 4 à 14 entre elles et par rapport à la structure porteuse 27. Les axes principaux 15 à 23 et 25 peuvent être pleins ou creux. Un deuxième ensemble d'axes 24, notés axes de rotation, permet d'articuler les galets 3 sur une poutre 9 à 14. En d'autres termes, les galets 3 sont montés mobiles en rotation respectivement autour des axes de rotation 24. Préférentiellement, les axes de rotation 24 sont montés fixes sur les poutres 9 à 14.In general, the device 1 comprises at least one roller 3 and at least two beams 4 to 14. The device 1 is intended to support the traction cable 2, more particularly the device 1 provides support and guidance to the cable 2. The traction cable 2 rests on rollers 3 which are configured for supporting and guiding traction cable 2. Beams 4 to 14 each comprise at least one axis 15 to 25. In addition, the installation comprises a supporting structure 27 fixed, and the beams 4 to 14 are articulated with respect to the supporting structure 27. A first set of axes 15 to 23 and 25, denoted main axes, makes it possible to articulate the beams 4 to 14 between them and with respect to the supporting structure 27. The main axes 15 to 23 and 25 can be solid or hollow. A second set of axes 24, denoted axes of rotation, makes it possible to articulate the rollers 3 on a beam 9 to 14. In other words, the rollers 3 are mounted mobile in rotation respectively around the axes of rotation 24. Preferably , the axes of rotation 24 are mounted fixed on the beams 9 to 14.

De manière générale, le dispositif 1 comprend au moins une poutre 4 à 8, notée poutre primaire, munie d'au moins un axe principal 15 à 23 et 25. Par ailleurs, le dispositif 1 comprend au moins une poutre 9 à 14, notée poutre secondaire, supportant au moins un galet 3. Une poutre secondaire 9 à 14 est montée mobile en pivotement autour d'un axe principal 19 à 23 et 25 monté sur une poutre primaire 6 à 8. Par ailleurs, les poutres primaires 4 à 8 peuvent être montées fixes sur la structure porteuse 27, ou montées mobiles en pivotement autour des autres axes principaux 15 à 18. De préférence, les axes principaux 15 à 23 et 25 sont montés fixes sur les poutres primaires 4 à 8, et les axes de rotation 24 sont montés fixes sur les poutres secondaires 9 à 14. Une poutre primaire spécifique 4 est également notée poutre support, car elle est montée mobile en pivotement autour d'un axe support 26. L'axe support 26 est monté fixe sur la structure porteuse 27.In general, the device 1 comprises at least one beam 4 to 8, denoted primary beam, provided with at least one main axis 15 to 23 and 25. Furthermore, the device 1 comprises at least one beam 9 to 14, denoted secondary beam, supporting at least one roller 3. A secondary beam 9 to 14 is pivotally mounted around a main axis 19 to 23 and 25 mounted on a primary beam 6 to 8. Furthermore, the primary beams 4 to 8 can be mounted fixed on the supporting structure 27, or mounted mobile in pivoting around the other main axes 15 to 18. Preferably, the main axes 15 to 23 and 25 are mounted fixed on the primary beams 4 to 8, and the axes of 24 are mounted fixed on the secondary beams 9 to 14. A specific primary beam 4 is also denoted support beam, because it is mounted so as to be able to pivot about a support axis 26. The support axis 26 is mounted fixed on the structure carrier 27.

Par exemple, comme illustré aux figures 1 et 2, le dispositif 1 comporte douze galets 3. Le dispositif 1 comporte onze poutres 4 à 14, dix axes principaux 15 à 23 et 25, et douze axes de rotation 24, représentés sur la figure 1. Dans l'exemple illustré aux figures 1 et 2, la première poutre primaire 4 comporte deux axes principaux 15, 16, autour desquels sont montées respectivement une deuxième poutre primaire 5 et une troisième poutre primaire 6, mobiles en pivotement. La deuxième poutre primaire 5 comporte deux axes principaux 17, 18, autour desquels sont montées respectivement une quatrième poutre primaire 7 et une cinquième poutre primaire 8, mobiles en pivotement. La quatrième poutre primaire 7 comporte deux axes principaux 19 et 25, autour desquels sont montées respectivement une première poutre secondaire 10 et une deuxième poutre secondaire 9, mobiles en pivotement.For example, as illustrated in figure 1 And 2 , the device 1 comprises twelve rollers 3. The device 1 comprises eleven beams 4 to 14, ten main axes 15 to 23 and 25, and twelve axes of rotation 24, represented on the figure 1 . In the example illustrated in figure 1 And 2 , the first primary beam 4 comprises two main axes 15, 16, around which are respectively mounted a second primary beam 5 and a third primary beam 6, pivotally movable. The second primary beam 5 has two main axes 17, 18, around which are respectively mounted a fourth primary beam 7 and a fifth primary beam 8, pivotally movable. The fourth primary beam 7 comprises two main axes 19 and 25, around which are respectively mounted a first secondary beam 10 and a second secondary beam 9, which can pivot.

La cinquième poutre primaire 8 comporte deux axes principaux 20, 21 autour desquels sont montées respectivement une troisième poutre secondaire 11 et une quatrième poutre secondaire 12, mobiles en pivotement.The fifth primary beam 8 has two main axes 20, 21 around which are respectively mounted a third secondary beam 11 and a fourth secondary beam 12, pivotally movable.

La troisième poutre primaire 6 comporte deux axes principaux 22, 23 autour desquels sont montées respectivement une cinquième poutre secondaire 13 et une sixième poutre secondaire 14, mobiles en pivotement.The third primary beam 6 comprises two main axes 22, 23 around which are respectively mounted a fifth secondary beam 13 and a sixth secondary beam 14, pivotally movable.

De façon générale, les galets 3 sont montés mobiles en rotation respectivement autour des axes de rotation 24, et les poutres 4 à 14 sont montées mobiles en pivotement les unes par rapport aux autres. On entend par « monté mobile en rotation », un élément pouvant effectuer une ou plusieurs rotations complètes autour d'un axe. On entend par « monté mobile en pivotement », un élément pouvant effectuer une partie de rotation inférieure à 360°, dans un sens de rotation ou dans l'autre.In general, the rollers 3 are mounted so as to be able to rotate respectively about the axes of rotation 24, and the beams 4 to 14 are mounted so as to be able to pivot relative to each other. “Movable in rotation” is understood to mean an element that can perform one or more complete rotations around an axis. “Movable in pivoting” is understood to mean an element capable of carrying out a part of rotation of less than 360°, in one direction of rotation or in the other.

Plus particulièrement, le dispositif 1 comporte au moins un élément de rattrapage 30 à 39 et au moins un élément de coopération 40 à 47. Un élément de rattrapage 30 à 39 est destiné à coopérer avec un élément de coopération 40 à 47 dans un état anormal de fonctionnement du dispositif afin de garantir l'appui et le guidage du câble tracteur. L'état anormal de fonctionnement du dispositif 1 correspond à une usure, voire exceptionnellement une rupture, d'un axe principal 15 à 23 et 25. De façon générale, au moins un élément de rattrapage 30 à 39 est monté sur une première poutre et au moins un élément de coopération 40 à 47 est monté sur une deuxième poutre. En particulier, un élément de coopération 40 à 47 est monté à distance d'un élément de rattrapage 30 à 39 dans un état normal de fonctionnement du dispositif 1. En d'autres termes, l'élément de coopération 30 à 39 n'est pas en contact d'un élément de rattrapage dans l'état normal de fonctionnement. On entend par état normal de fonctionnement, la situation où la deuxième poutre pivote autour de l'axe principal 15 à 23 et 25 monté sur la première poutre. Plus particulièrement, l'élément de rattrapage 30 à 39 est configuré pour rattraper la deuxième poutre et l'élément de coopération 40 à 47 est configuré pour venir en contact avec l'élément de rattrapage 30 à 39 dans l'état anormal de fonctionnement.More particularly, the device 1 comprises at least one catch-up element 30 to 39 and at least one cooperation element 40 to 47. A catch-up element 30 to 39 is intended to cooperate with a cooperation element 40 to 47 in an abnormal state. operation of the device in order to guarantee the support and guidance of the traction cable. The abnormal operating state of device 1 corresponds to wear, or even exceptionally breakage, of a shaft main 15 to 23 and 25. Generally, at least one take-up element 30 to 39 is mounted on a first beam and at least one cooperation element 40 to 47 is mounted on a second beam. In particular, a cooperation element 40 to 47 is mounted at a distance from a take-up element 30 to 39 in a normal operating state of the device 1. In other words, the cooperation element 30 to 39 is not not in contact with a take-up element in the normal operating state. The term “normal operating state” means the situation where the second beam pivots around the main axis 15 to 23 and 25 mounted on the first beam. More particularly, the take-up element 30 to 39 is configured to catch up with the second beam and the cooperating element 40 to 47 is configured to come into contact with the take-up element 30 to 39 in the abnormal operating state.

Avantageusement, un élément de rattrapage 30 à 39 et un élément de coopération 40 à 47 sont conformés pour permettre un pivotement de la deuxième poutre dans l'état anormal de fonctionnement. Ainsi, lorsque l'élément de coopération 40 à 47 vient en contact avec l'élément de rattrapage 30 à 39, la deuxième poutre peut encore pivoter et garantir la fonction d'appui et de guidage du dispositif 1. En d'autres termes, dans l'état anormal de fonctionnement, la deuxième poutre est déplacée par l'appui du câble tracteur 2, et l'élément de coopération 40 à 47 se rapproche de l'élément de rattrapage 30 à 39. Dans une situation limite de l'état anormal de fonctionnement, l'élément de coopération 40 à 47 vient en contact de l'élément de rattrapage 30 à 39.Advantageously, a take-up element 30 to 39 and a cooperation element 40 to 47 are shaped to allow pivoting of the second beam in the abnormal operating state. Thus, when the cooperation element 40 to 47 comes into contact with the catch-up element 30 to 39, the second beam can still pivot and guarantee the support and guiding function of the device 1. In other words, in the abnormal operating state, the second beam is moved by the support of the traction cable 2, and the cooperation element 40 to 47 approaches the take-up element 30 to 39. In a limit situation of the abnormal state of operation, the cooperation element 40 to 47 comes into contact with the take-up element 30 to 39.

Par exemple, un élément de coopération 40 à 47 peut être une pièce de coopération 40, 44, 45, 46, 47 montée en saillie de la deuxième poutre et l'élément de rattrapage 30 à 39 correspond à un logement de rattrapage 30, 34, formé sur la première poutre et configuré pour recevoir la pièce de coopération 40, 44, 45, 46, 47 dans l'état anormal de fonctionnement.For example, a cooperation element 40 to 47 can be a cooperation part 40, 44, 45, 46, 47 mounted projecting from the second beam and the catch-up element 30 to 39 corresponds to a catch-up housing 30, 34 , formed on the first beam and configured to receive the cooperating part 40, 44, 45, 46, 47 in the abnormal operating state.

En variante, l'élément de coopération 40 à 47 correspond à un logement de coopération 41, 42, 43 formé sur la deuxième poutre et l'élément de rattrapage 30 à 39 correspond à une pièce de rattrapage 31, 32, 33, 35 à 39 montée en saillie de la première poutre et configurée pour s'introduire dans le logement de coopération 41, 42, 43 dans l'état anormal de fonctionnement.Alternatively, the cooperation element 40 to 47 corresponds to a cooperation housing 41, 42, 43 formed on the second beam and the catch-up element 30 to 39 corresponds to a retrofit piece 31, 32, 33, 35 to 39 mounted projecting from the first beam and configured to be introduced into the cooperation housing 41, 42, 43 in the abnormal operating state.

Sur la figure 3, on a représenté un mode de réalisation, dans lequel la première poutre 6 comporte deux flasques extérieurs 70, 71 et la deuxième poutre 14 est située entre les deux flasques extérieurs 70, 71. Cette configuration des poutres 6, 14 est également appelée configuration en chape. Dans cette configuration, la deuxième poutre 14 est montée à pivotement sur l'axe principal 23, par l'intermédiaire d'un palier 50. Dans ce mode de réalisation, l'élément de coopération 47 est un axe cylindrique, par exemple un tube ou une tige pleine, et la première poutre 6 comporte deux éléments de rattrapage 30 correspondant à deux logements formés respectivement sur les deux flasques 70, 71 extérieurs.On the picture 3 , an embodiment has been shown, in which the first beam 6 comprises two outer flanges 70, 71 and the second beam 14 is located between the two outer flanges 70, 71. This configuration of the beams 6, 14 is also called a configuration in screed. In this configuration, the second beam 14 is pivotally mounted on the main axis 23, via a bearing 50. In this embodiment, the cooperation element 47 is a cylindrical axis, for example a tube or a solid rod, and the first beam 6 comprises two adjustment elements 30 corresponding to two housings formed respectively on the two outer flanges 70, 71.

Sur la figure 4, les poutres 6 et 14 sont également dans une configuration en chape. La deuxième poutre 14 comporte deux éléments de coopération 42, 43 correspondant à deux logements formés respectivement sur deux flasques 45, 46 de la deuxième poutre 14. L'élément de rattrapage 38 est un axe cylindrique, par exemple un tube ou une tige pleine.On the figure 4 , the beams 6 and 14 are also in a yoke configuration. The second beam 14 comprises two cooperation elements 42, 43 corresponding to two housings formed respectively on two flanges 45, 46 of the second beam 14.

Dans ce mode de réalisation préféré, le dispositif 1 comporte un premier élément de coopération 40 et un deuxième élément de coopération 41 montés sur respectivement les deux flasques 45, 46 de la deuxième poutre 14. Le premier élément de coopération 40 est un axe cylindrique, par exemple un tube ou une tige pleine. Le deuxième élément de coopération 41 est un logement. En outre, la première poutre 6 comporte un premier élément de rattrapage 30 et un deuxième élément de rattrapage 31 montés respectivement sur les deux flasques extérieurs 70, 71. Le premier élément de rattrapage 30 est un logement et le deuxième élément de rattrapage 31 est une pièce de rattrapage 31 montée en saillie de la première poutre 6. En outre, le deuxième élément de coopération 41 est un logement formé sur une plaque de support 54 montée sur le flasque 46 de la deuxième poutre 14.On the figure 5 to 10 a preferred embodiment has been shown in which a first beam 6 and a second beam 14 are also in a yoke configuration. In this preferred embodiment, the device 1 comprises a first cooperation element 40 and a second cooperation element 41 respectively mounted on the two flanges 45, 46 of the second beam 14. The first cooperation element 40 is a cylindrical axis, for example a tube or a solid rod. The second cooperating element 41 is a housing. In addition, the first beam 6 comprises a first take-up element 30 and a second take-up element 31 respectively mounted on the two outer flanges 70, 71. The first take-up element 30 is a housing and the second take-up element 31 is a catch-up piece 31 mounted projecting from the first beam 6. In Furthermore, the second cooperation element 41 is a housing formed on a support plate 54 mounted on the flange 46 of the second beam 14.

Sur les figures 11 et 12, on a représenté un autre mode de réalisation dans lequel les première et deuxième poutres 5, 8 sont également en configuration en chape. Dans ce mode de réalisation, le dispositif d'appui et de guidage 1 est du type support du câble tracteur 2. En outre, le dispositif 1 comporte un premier élément de coopération 42 et un deuxième élément de coopération 42 montés sur respectivement les deux flasques 45, 46 de la deuxième poutre 8. Les deux éléments de coopération 42, 43 sont des logements. En outre, la première poutre 5 comporte un premier élément de rattrapage 32 et un deuxième élément de rattrapage 33 montés respectivement sur les deux flasques extérieurs 70, 71. Les deux éléments de rattrapage 32, 33 sont deux axes cylindriques, par exemple deux tubes ou deux tiges pleines.On the figure 11 And 12 , another embodiment has been shown in which the first and second beams 5, 8 are also in the yoke configuration. In this embodiment, the support and guide device 1 is of the support type for the traction cable 2. In addition, the device 1 comprises a first cooperation element 42 and a second cooperation element 42 respectively mounted on the two flanges 45, 46 of the second beam 8. The two cooperation elements 42, 43 are housings. In addition, the first beam 5 comprises a first take-up element 32 and a second take-up element 33 mounted respectively on the two outer flanges 70, 71. The two take-up elements 32, 33 are two cylindrical axes, for example two tubes or two solid stems.

Sur les figures 13 et 14, on a représenté un mode de réalisation, dans lequel la première poutre 6 comporte deux flasques extérieurs 70, 71 délimitant un espace interne entre les deux flasques extérieurs 70, 71 et la deuxième poutre 14 est située à l'extérieur de l'espace interne. Cette configuration des poutres 6, 14 est également appelée configuration en porte-à-faux. Dans cette configuration, la deuxième poutre 14 est montée à pivotement sur l'axe principal 23, par l'intermédiaire d'un palier 50. L'axe principal 23 est maintenu fixe sur la première poutre par une butée de fixation 55. Dans ce mode de réalisation, le dispositif 1 comporte un premier élément de coopération 44 correspondant à une prolongation 44 de la deuxième poutre 14 le long de l'axe principal 23, et un deuxième élément de coopération 45 correspondant à un premier flasque de la deuxième poutre 14. En outre, le dispositif 1 comporte un premier élément de rattrapage 34 correspondant à un ergot 34 monté en saillie d'un flasque extérieur 71 de la première poutre 6. L'ergot 34 forme un logement susceptible de recevoir la prolongation 44 de la deuxième poutre 14. Le dispositif 1 comporte également un deuxième élément de rattrapage 35 correspondant à une pièce en forme de main et montée en saillie du flasque extérieur 71 pour rattraper le premier flasque 45 de la deuxième poutre.
