Abstract

A parking track of a gondola lift or chair-lift comprises straight sections and curved sections and chains for driving cars on this track. On the straight sections the cars follow one another closely or almost touching and on the curved sections with a greater clearance sufficient to pass without the risk of one another colliding.

Description

L'invention est relative à une installation de transport à câble aérien, notamment télécabine ou télésiège ayant des véhicules, notamment des cabines et des sièges suspendus à des pinces d'accouplement au câble, ayant des galets de roulement, lesdites pinces étant susceptibles d'être débrayées du câble aérien dans les stea- tions et de circuler sur une voie de transfert et/ou de garage avant d'être réaccouplées au câble, ladite voie comprenant des tronçons droits et des tronçons courbes et un moyen d'entraînement des véhicules.The invention relates to an overhead cable transport installation, in particular a cable car or chairlift having vehicles, in particular cabins and seats suspended from cable coupling clamps, having rollers, said clamps being capable of be disengaged from the overhead cable in stations and travel on a transfer and / or garage track before being re-coupled to the cable, said track comprising straight sections and curved sections and a means of driving the vehicles.

Dans une installation connue du genre mentionné (voir p. ex. celle décrite dans EP-A-0 114 129), les véhicules défilent à vitesse rapide sur la ligne, en étant entraînés par le câble aérien et à vitesse lente dans la station après désaccouplement du câble. Les véhicules désaccoulpés du câble circulent sur la voie de transfert de la station en se tamponnant souvent les uns contre les autres et il a déjà été proposé d'équiper la voie de transfert d'une chaîne de propulsion maintenant une certaine distance entre les véhicules. Cet écartement est suffisant pour éviter tout contact ou collision entre les véhicules qui se suivent, même sur les tronçons courbes de la voie, mais il diminue le nombre de véhicules présents simultanément sur la voie. L'intervalle entre les véhicules dans les zones d'embarquement et de débarquement peut être gênant. Le même problème se pose pour les voies de garage équipées de moyens d'entraînement où l'écartement des véhicules sur les tronçons droits diminue la capacité de stockage.In a known installation of the kind mentioned (see for example that described in EP-A-0 114 129), the vehicles pass at high speed on the line, being driven by the aerial cable and at low speed in the station after cable uncoupling. Vehicles released from the cable travel on the station transfer path, often buffering against each other and it has already been proposed to equip the transfer path with a propulsion chain maintaining a certain distance between the vehicles. This spacing is sufficient to avoid any contact or collision between the vehicles which follow one another, even on curved sections of the track, but it reduces the number of vehicles present simultaneously on the track. The interval between vehicles in the embarkation and disembarkation areas can be inconvenient. The same problem arises for the garage tracks equipped with drive means where the spacing of the vehicles on the straight sections decreases the storage capacity.

La présente invention a pour but de permettre la réalisation d'un moyen d'entraînement des véhicules dans la station sans risque de tamponnement tout en maintenant un écartement minimal.The present invention aims to allow the realization of a vehicle drive means in the station without risk of buffering while maintaining a minimum spacing.

L'installation selon l'invention est caractérisée en ce que ledit moyen d'entraînement est agencé pour entraîner lesdits véhicules dans lesdites courbes à une vitesse supérieure à celle des véhicules sur les tronçons droits de façon que l'espacement desdits véhicules qui se suivent de près ou qui se touchent quasiment sur les tronçons droits, est augmenté pour le franchissement des tronçons courbes sans risque de collision entre les véhicules se suivant.The installation according to the invention is characterized in that said drive means is arranged to drive said vehicles in said curves at a speed greater than that of vehicles on straight sections so that the spacing of said vehicles which follow one another near or almost touching each other on straight sections, is increased for crossing curved sections without risk of collision between following vehicles.

L'écartement des véhicules est déterminé d'une part par le rayon de courbure de la plus forte courbe de la voie et d'autre part par les dimensions, notamment la largeur des véhicules. Pour varier cet écartement il suffit de modifier la vitesse d'entraînement, en l'occurrence d'accéle- rer les véhicules dans les courbes, tout en conservant la vitesse lente sur les tronçons droits correspondant à la vitesse optimale pour l'embarquement et le débarquement des passagers.The spacing of the vehicles is determined on the one hand by the radius of curvature of the steepest curve of the track and on the other hand by the dimensions, in particular the width of the vehicles. To vary this spacing, it is sufficient to modify the drive speed, in this case to accelerate the vehicles in the curves, while maintaining the slow speed on the straight sections corresponding to the optimal speed for boarding and disembarking of passengers.

L'accélération dans les courbes est avantageu- seument obtenue par un moyen d'entraînement séparé, notamment une chaîne à vitesse synchronisée plus rapide pour conserver l'échelonnement régulier. La chaîne peut être replacée par une roue portant sur la circonférence des taquets d'entraînement ou par un train de roues à bandage pneumatique du genre utilisé sur les tronçons d'accélération et de décéleration. La même chaîne est utilisable pour l'entraînement sur les tronçons droits et courbes, si l'on prend soin de faire suivre aux véhicules une trajectoire plus longue dans les courbes que celle de la chaîne pour obtenir l'accélération recherchée. Les moyens d'entraînement sont bien entendu adaptés au type d'installation, ces moyens étant simplifiés lorsqu'ils équipent une voie de stockage et plus élaborés pour une voie de transfert à passage permanent des véhicules.The acceleration in the curves is advantageously obtained by a separate drive means, in particular a chain with faster synchronized speed to keep the regular staggering. The chain can be replaced by a wheel bearing on the circumference of the driving cleats or by a wheel train with pneumatic tires of the type used on the acceleration and deceleration sections. The same chain can be used for driving on straight and curved sections, if care is taken to make vehicles follow a longer trajectory in curves than that of the chain to obtain the desired acceleration. The drive means are of course adapted to the type of installation, these means being simplified when they equip a storage path and more elaborate for a transfer path with permanent passage of vehicles.

L'invention est applicable à toute installation à véhicules débrayables, monocâble ou multicâble, notamment aux télécabines, dans lesquelles les chocs entre les véhicules doivent être évités pour des raisons d'usure du matériel et de confort des passagers.The invention is applicable to any installation with detachable vehicles, single cable or multi cable, in particular to cable cars, in which impacts between vehicles must be avoided for reasons of wear of the equipment and passenger comfort.

Sur les figures, une station d'une télécabine à câble porteurtracteur 10 comporte une poulie 12 d'extrémité à axe vertical sur laquelle passe le câble 10. Au câble 10 sont accouplées en ligne des cabines 14, qui à l'entrée 16 de la station sont désaccouplées du câble 10. A la sortie 18 de la station les cabines 14 sont réaccouplées à la voie opposée du câble d'une manière bien connue. Chaque cabine 14 comporte une suspente 20 de fixation à un chariot 22 de support d'une ou de deux pinces 24, sollicitées en position de fermeture par des ressorts 26. Un levier de commande 28 coopère avec un rail de commande 30 pour commander l'ouverture et la fermeture de la pince et l'accouplement et le désaccouplement de la pince 24 au câble 10. Le chariot 22 à galets 32, 34 roule dans la station, après désaccouplement du câble 10, sur un rail 40 de transfert reliant les deux voies du câble 10 en étant entraîné soit par des roues à pneumatiques 38, agissant sur une face de friction 36 du chariot 22, soit par une chaîne 46 ayant des taquets d'entraînement 48 qui coopèrent avec la suspente 20. Le guide 50 de la chaîne 46 est solidarisé par un support 52 au rail 40. Des rails 44 de garage sont raccordés aux rails 40 de transfert par des aiguillages 54 permettant l'orientation des cabines vers la zone de stockage en fin de journée et le recyclage des cabines 14 au démarrage de l'installation. Les rails 44 de garage sont disposés en boucle pour obtenir un capacité maximale de stockage des cabines, la trajectoire dépendant bien entendu des surfaces disponibles. Les roues à pneumatiques 38 sont disposées à l'entrée 16 de la station pour décélérer les cabines désaccouplées du câble, à la sortie 18 pour accélérer les carbines avant leur réaccouplement au câble et dans les zones d'aiguillages 54. La chaîne 46 de transfert s'étend le long du rail 40 pour entraîner à vitesse réduite les cabines 14 pour l'embarquement et le débarquement des passagers. De telles télécabines sont bien connues des spécialistes.In the figures, a station of a cable car with a pulling carrier cable 10 comprises a pulley 12 at the end with a vertical axis over which the cable 10 passes. To the cable 10 are cabins 14 connected in line, which at the entrance 16 of the station are uncoupled from the cable 10. At the outlet 18 of the station the cabins 14 are re-coupled to the opposite channel of the cable in a well known manner. Each cabin 14 includes a hanger 20 for attachment to a carriage 22 for supporting one or two clamps 24, urged in the closed position by springs 26. A control lever 28 cooperates with a control rail 30 to control the opening and closing of the clamp and coupling and uncoupling of the clamp 24 to the cable 10. The carriage 22 with rollers 32, 34 rolls in the station, after uncoupling the cable 10, on a transfer rail 40 connecting the two cable tracks 10 being driven either by pneumatic wheels 38, acting on a friction face 36 of the carriage 22, or by a chain 46 having driving cleats 48 which cooperate with the hanger 20. The guide 50 of the chain 46 is joined by a support 52 to the rail 40. Garage rails 44 are connected to the transfer rails 40 by switches 54 allowing the cabins to be oriented towards the storage area at the end of the day and the cabs 14 to be recycled when the installation starts. The garage rails 44 are arranged in a loop to obtain a maximum storage capacity for the cabins, the trajectory of course depending on the surfaces available. The pneumatic wheels 38 are arranged at the inlet 16 of the station to decelerate the uncoupled cabins of the cable, at the outlet 18 to accelerate the carbines before their re-coupling to the cable and in the switching zones 54. The transfer chain 46 extends along the rail 40 to drive the cabins 14 for boarding and disembarking passengers at reduced speed. Such gondolas are well known to specialists.

En se référant plus particulièrement à la figure 5, on voit que les rails de garage 44 comportent des tronçons droits 56 parallèles, reliés aux extrémités par des tronçons courbes 58, 60. L'écartement des tronçons parallèles droits 56 est légèrement supérieure à la largeur des cabines 14 pour stocker ces dernières en rangées à écartement minimal et le rayon des courbes 58, 60 est bien entendu déterminé par cet écartement. Les cabines 14 sont entraînées positivement le long des rails 44 de garage par des chaînes 62, 64, 66 s'étendant respectivement suivant les tronçons droits 56, les tronçons courbes extérieurs 58 et les tronçons courbes intérieurs 60. La ou les chaînes 62 des tronçons droits 56 portent des taquets d'entraînement 68 dont l'écartement I est légèrement supérieure à la longueur des carbines 14, de telle manière que deux cabines 14 successives sont quasiment au contact mais sans risque de se tamponner. On évite ainsi les chocs entre les cabines 14 tout en occupant un espace minimal de stockage. Il est facile de voir que cet intervalle est trop faible pour le parcours d'un tronçon courbe 58, 60, les angles internes des cabines 14 venant au contact. Selon l'invention, la carbine abordant un tronçon courbe 58, 60 est prise en charge par une autre chaîne 64, 66 ayant des taquets d'entraînement 70, 72 à écartement l', 1" supérieur, garantissant un passage de la courbe sans collision entre les cabines. Pour conserver une circulation continue des cabines 14 la vitesse des chaînes 64, 66 doit être supérieure à celle de la chaîne 62, dans le rapport des écartements. Dans l'exemple illustré par les figures 2 et 5 les chaînes successives 62, 64; 64,66 passent sur des roues dentées 74, 76 solidaires d'un même axe 78 entraîné par un moteur 80, le diamètre de la roue 74 de la chaîne 62 étant inférieur au diamètre de la roue 76 entraînant la chaîne 64 plus rapide. Le synchronisme est ainsi parfaitement conservé et les cabines 14 se déplacent plus rapidement sur les tronçons courbes 58, 60 que sur les tronçons droits 56. La même chaîne 62 peut s'étendre le long de deux tronçons droits 56 ou de l'ensemble des tronçons droits des voies de garage, l'entraînement pouvant être réalisé d'une manière quelconque, par exemple dérivé du câble 10. Les brins de retour des chaînes peuvent suivre une trajectoire quelconque, soit parallèle au brin actif, soit raccourcie. De même, tous les tronçons courbes 58,60 peuvent être équipés d'une seule chaîne, la solution à plusieurs chaînes étant toutefois préférable lorsque les tronçons sont éloignés les uns des autres. Ces chaînes peuvent avoir des taquets 70, 72 à espacement différents selon le rayon de courbure de la courbe ou selon le type de courbe, extérieure ou intérieure, la vitesse étant dans ce cas également différente. Il est clair que l'entraînement peut être effectué d'une manière différente sur certains ou sur l'ensemble des tronçons, notamment par des roues à bandages pneumatiques et que les trajectoires sont quelconques.Referring more particularly to FIG. 5, it can be seen that the garage rails 44 comprise straight straight sections 56 parallel, connected at the ends by curved sections 58, 60. The spacing of the straight parallel sections 56 is slightly greater than the width cabins 14 for storing the latter in rows with minimum spacing and the radius of the curves 58, 60 is of course determined by this spacing. The cabins 14 are positively driven along the garage rails 44 by chains 62, 64, 66 extending respectively along the straight sections 56, the curved outside sections 58 and the inside curved sections 60. The chain or chains 62 of the sections straight 56 carry drive tabs 68 whose spacing I is slightly greater than the length of the carbines 14, so that two successive cabins 14 are almost in contact but without the risk of being buffered. This prevents shocks between the cabins 14 while occupying a minimum storage space. It is easy to see that this interval is too small for the course of a curved section 58, 60, the internal angles of the cabins 14 coming into contact. According to the invention, the carbine approaching a curved section 58, 60 is taken over by another chain 64, 66 having driving tabs 70, 72 with spacing 1, 1 "higher, guaranteeing a passage of the curve without collision between the cabins In order to maintain a continuous circulation of the cabins 14 the speed of the chains 64, 66 must be greater than that of the chain 62, in the ratio of the spacings In the example illustrated by FIGS. 62, 64; 64,66 pass on toothed wheels 74, 76 integral with the same axis 78 driven by a motor 80, the diameter of the wheel 74 of the chain 62 being less than the diameter of the wheel 76 driving the chain 64 Synchronism is thus perfectly preserved and the cabins 14 move more quickly on the curved sections 58, 60 than on the straight sections 56. The same chain 62 can extend along two straight sections 56 or the set of three straight lines of the garage tracks, the drive being able to be carried out in any way, for example derived from the cable 10. The return strands of the chains can follow any trajectory, either parallel to the active strand, or shortened. Likewise, all the curved sections 58, 60 can be equipped with a single chain, the solution with several chains being however preferable when the sections are distant from each other. These chains can have tabs 70, 72 at different spacing depending on the radius of curvature of the curve or according to the type of curve, exterior or interior, the speed in this case also being different. It is clear that the drive can be carried out in a different way on some or on all of the sections, in particular by wheels with pneumatic tires and that the trajectories are arbitrary.

La figure 6 illustre une variante de réalisation pour un entraînement à vitesse différentielle par une même chaîne 82 à taquets 84 relativement longs. La chaîne 82 suit la trajectoire du rail de garage 44 du côté intérieur à une certaine distance en passant sur une roue dentée 86 concentrique au tronçon courbe 58. Il est facile de voir qu'une vitesse angulaire w de la roue 86 impose une vitesse linéaire wRi, R, étant le rayon de la roue 86, aux cabines sur le tronçon droit 56 et une vitesse circonférentielle wR2 sur le tronçon courbe 58, R2 étant le rayon de courbure de la courbe 58. L'effet d'accélération est ainsi obtenu automatiquement. D'autres réalisations analogues sont concevables, la roue denté 86 pouvant être remplacée par d'autres guidages.FIG. 6 illustrates an alternative embodiment for a differential speed drive by the same chain 82 with relatively long cleats 84. The chain 82 follows the trajectory of the garage rail 44 from the interior side at a certain distance passing over a toothed wheel 86 concentric with the curved section 58. It is easy to see that an angular speed w of the wheel 86 imposes a linear speed wR i , R, being the radius of the wheel 86, at the cabins on the straight section 56 and a circumferential speed wR 2 on the curved section 58, R 2 being the radius of curvature of the curve 58. The acceleration effect is thus obtained automatically. Other similar embodiments are conceivable, the toothed wheel 86 can be replaced by other guides.

Le fonctionnement de la télécabine découle de l'exposé précédent.The operation of the gondola follows from the previous presentation.

L'invention a été décrite comme étant appliquée à des voies de garage, mais elle présente les mêmes avantages de rapprochement maximal des cabines sur une voie de transfert 40, évitant ainsi des espacements des cabines alignées lelong des quais d'embarquement et de débarquement. Si la voie de transfert est utilisée comme voie de stockage, sa capacité est accrue en conséquence. Le gain est d'autant plus important que les véhicules, qui peuvent être des cabines, bennes ou sièges, sont larges et l'invention est applicable à toute installation, monocâble, bicâble débrayable à circulation continue ou non. Si le rayon de courbure de certaines courbes est suffisamment grand pour éviter des collisions, ces courbes ne nécessitent pas un entraînement accéléré des cabines.The invention has been described as being applied to garage tracks, but it has the same advantages of maximum closeness of the cabins on a transfer track 40, thus avoiding spacings of the cabins aligned along the embarkation and disembarkation platforms. If the transfer route is used as a storage route, its capacity is increased accordingly. The gain is all the more important as the vehicles, which can be cabins, tippers or seats, are wide and the invention is applicable to any installation, single-cable, disengageable double-cable with continuous circulation or not. If the radius of curvature of certain curves is large enough to avoid collisions, these curves do not require accelerated cab driving.

Claims (9)

1. An aerial ropeway transport installation, notably a gondola lift or chair-lift having vehicles notably cars (14) or chairs suspended by grips (22) for coupling to the rope, having roller sheaves (32), said grips being able to be detached from the aerial ropeway in the terminals and to run on the transfer (40) and/or parking track (44) before being recoupled to the rope, said track (40, 44) comprising straight sections (56) and curved sections (50, 60), and a means (62, 64, 66) of driving the vehicles (14), characterized in that said means of driving (62, 64, 66) are arranged to drive the vehicles (14) on the curved sections (58, 60) at a greater speed than that of the vehicles over the straight sections (56) so that the distance of said vehicles following one another closely or almost touching, on the straight sections (56) is increased to pass the curved sections (58, 60) without the risk of the vehicles following one another colliding.
2. An installation according to Claim 1, characterized in that the distance apart of the vehicles (14) in the curves is sufficient to prevent bumping between the inside corners of the vehicles (14) on the curves.
3. An installation according to Claim 1 or 2, characterized in that said track (40, 44) constitutes a vehicle storage track on which the vehicles are adjacent to one another on the straight sections (56) and separated from one another in the curves (58,60).
4. An installation according to Claim 1, 2 or 3, characterized in that said track is a transfer track from the outgoing serial ropeway track to the return track on which transfer track the vehicles (14) run at low speed for loading and unloading of the passengers being almost end to end on the straight sections and spaced slightly apart on the curved sections.
5. An installation according to one of the preceding claims, characterized in that it comprises an apart means (64, 66) of driving over the curved sections (58, 60) with a driving speed greater than the driving speed of the vehicle driving means (62) over the straight sections (56).
6. An installation according to Claim 5, characterized in that it comprises a positive vehicle (14) driving means (62) over the straight sections (56), the latter means being synchronized with the driving means (64, 66) in the curves (58, 60) having a greater speed.
7. An installation according to one of the preceding claims, characterized in that it comprises a chain (62) with pins (68) to drive the vehicles over a straight section (56) and a chain (64, 66) with drive pins (70, 72) over the curved sections (58, 60) said chains (62, 64, 66) being driven at differential speeds and the distance between the pins (68) of the chain (62) being smaller than the distance between the pins (70, 72) of the chain (64, 66), these gaps corresponding to the minimum distance between vehicles without the risk of them bumping into one another.
8. An installation according to Claim 7, characterized in that it comprises a curved section (58) joining two parallel straight sections (56), a drive chain (62) extending in a closed loop along the two straight sections (56) passing on countergear cog-wheels (74) at the end of these sections (56) and a drive chain (64) being endless and extending along the curved section (58) passing over countergear cogwheels (76) secured to the same spindle (78) as the straight section (56) cogwheels (74) to be driven at the same speed of rotation, the diameter of the curved section cogwheels (76) being greater than that of the straight section cogwheels (74).
9. An installation according to one of the Claims 1 to 4, characterized in that it comprises a drive chain (82) common to the straight sections (56) and the curved sections, the trajectory followed by the vehicles (14) on the curved sections (58,60) being longer than the trajectory of said chain along these curved sections to accelerate the movement of the vehicles (14) through the curves.
