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 towing cable transport installations are equipped with support and guiding devices, such as balancers, for maintaining and guiding the towing cables in motion between the passenger embarkation and disembarkation stations. Generally, the balances are carried by pylons and are equipped with rotating rollers on which the traction cable rests. The rollers are mounted to rotate freely 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 vehicle clamp over the rollers.

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, an axis is used, which is an elongated part, to articulate in rotation or in pivoting a mobile element relative to a support, mobile or fixed, the axis being mounted fixed on the support. The axis of rotation is a part balance and it may be subject to failures, such as wear or in exceptional situations breakage. Its rupture would cause the fall of all the elements of the balance.
Les balanciers sont des éléments complexes est 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.Balances are complex components and are therefore regularly inspected to check their condition. In particular, it may be necessary to disassemble a balance in order to control with precision the possibly worn parts which must be replaced, in particular the axes of rotation. Disassembling a balance is a long and delicate operation.

Sur les
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, permettent 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, permettent 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
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
Par exemple, comme illustré aux
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
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
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
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
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
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
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.As a variant, the
