Description

L'invention est relative à une installation à câble aérien, notamment une télécabine ayant des véhicules accouplés en ligne à deux câbles parallèles porteurs-tracteurs à défilement continu par une suspente s'étendant dans lé plan vertical de symétrie des câbles et articulée à un chariot portant au moins une paire de pinces débrayables pour solidariser le chariot aux deux câbles en ligne et pour désaccoupler le véhicule dans les stations par débrayage des pinces pour un embarquement et/ou débarquement à vitesse réduite ou nulle des passagers, chaque pince prenant appui en position embrayée de la pince sur la face supérieure du câble et présentant une faible saillie vers le haut et une paire de mors ouverts vers le bas, pour enserrer latéralement le câble, l'extrémité des mors affleurant ou dépassant faiblement la face inférieure du câble pour faciliter le passage sur et sous les galets de support des câbles.The invention relates to an overhead cable installation, in particular a gondola lift having vehicles coupled in line to two parallel carrier-tractor cables with continuous travel by a hanger extending in the vertical plane of symmetry of the cables and articulated to a carriage. carrying at least one pair of disengageable clamps for securing the carriage to the two cables in line and for uncoupling the vehicle in stations by disengaging the clamps for boarding and / or disembarking at reduced or zero speed of passengers, each clamp taking support in position engaged with the clamp on the upper face of the cable and having a small upward projection and a pair of jaws open downward, for laterally enclosing the cable, the end of the jaws flush or slightly protruding from the underside of the cable to facilitate the passage over and under the cable support rollers.

La demande de brevet européen EP-A-0 093 680 décrit une installation du genre mentionné, . présentant une grande stàbilité latérale, grâce à un appui sur deux câbles espacés susceptibles de reprendre les efforts latéraux, notamment exercés par le vent sur les véhicules. Les véhicules de cette installation connue sont stables, mais ils comportent des suspentes conventionnelles relativement longues et leur gabarit est important.European patent application EP-A-0 093 680 describes an installation of the kind mentioned,. having great lateral stability, by pressing on two spaced cables capable of resuming lateral forces, in particular exerted by the wind on vehicles. The vehicles of this known installation are stable, but they have relatively long conventional lines and their size is large.

Un premier but de la présente invention est la réalisation d'une télécabine ayant des véhicules à suspente courte et à grande stabilité.A first object of the present invention is the realization of a gondola having vehicles with short suspension and high stability.

Un deuxième but est de permettre un dégagement aisé du véhicule désaccouplé des câbles dans les stations.A second aim is to allow easy release of the uncoupled vehicle from the cables in the stations.

L'installation selon l'invention est caractérisée en ce que ledit chariot est disposé au-dessus et à faible écartement du toit du véhicule, les deux câbles étant espacés d'une distance supérieure à la largeur du véhicule, ce dernier étant dégagé dans les stations desdits câbles par un mouvement relatif vers le haut par rapport aux câbles.The installation according to the invention is characterized in that said carriage is disposed above and at a small distance from the roof of the vehicle, the two cables being spaced apart by a distance greater than the width of the vehicle, the latter being cleared in the stations of said cables by a relative upward movement relative to the cables.

En augmentant l'écartement des câbles porteurs-tracteurs la stabilité latérale du véhicule est accrue notablement, ce qui permet de réduire la longueur de la suspente, en l'occurrence de rapprocher l'axe de suspension du centre de gravité du véhicule, tout en conservant une stabilité suffisante. Selon l'invention, l'écartement des câbles est supérieur à la largeur du véhicule, ce qui permet un dégagement aisé du véhicule désaccouplé des câbles, par exemple par une déviation vers le bas des câbles dans les stations. L'installation conserve les pinces standard en appui sur les câbles, ainsi que le système d'entraînement des câbles en synchronisme des installations connues, seul l'encombrement, en l'occurrence la largeur des pylônes étant légèrement augmentée.By increasing the spacing of the carrier cables the lateral stability of the vehicle is significantly increased, which reduces the length of the hanger, in this case bringing the suspension axis closer to the center of gravity of the vehicle, while retaining sufficient stability. According to the invention, the spacing of the cables is greater than the width of the vehicle, which allows easy release of the uncoupled vehicle from the cables, for example by a downward deflection of the cables in the stations. The installation keeps the standard clamps resting on the cables, as well as the cable drive system in synchronism with known installations, only the bulk, in this case the width of the pylons being slightly increased.

Le chariot porte deux paires de pinces, faisant saillie latéralement de part et d'autre du véhicule, dont la suspente raccourcie est articulée sur un axe transversal du châssis du chariot. Cet axe peut être constitué par une simple poutre transversale, disposée sensiblement au niveau des pinces, la suspente étant articulée au milieu de la poutre. Selon une variante de réalisation le chariot porte dans sa partie centrale une chaise de support d'un axe, décalé vers le haut, pour permettre un allongement de la suspente articulée sur cet axe. Cette dernière solution conserve le faible gabarit en hauteur de l'ensemble véhicule- chariot tout en disposant d'une suspente plus longue.The carriage carries two pairs of clamps, projecting laterally on either side of the vehicle, the shortened hanger of which is articulated on a transverse axis of the chassis of the carriage. This axis can be constituted by a simple transverse beam, arranged substantially at the level of the clamps, the hanger being articulated in the middle of the beam. According to an alternative embodiment, the carriage carries in its central part a support chair for an axis, offset upwards, to allow an extension of the hanger articulated on this axis. The latter solution retains the small height gauge of the vehicle-trolley assembly while having a longer hanger.

La longueur du véhicule inventif est avantageusement inférieure à sa largeur pour limiter son inclinaison lors d'un déséquilibre de la charge concentrée à l'avant ou à l'arrière. La longueur du chariot est par contre supérieure au quart de sa largeur pour assurer par les quatre pinces disposées en rectangle un quadrilatère rigide de liaison entre les deux câbles.The length of the inventive vehicle is advantageously less than its width to limit its inclination during an imbalance of the load concentrated at the front or at the rear. The length of the carriage, on the other hand, is greater than a quarter of its width to ensure, by the four clamps arranged in a rectangle, a rigid quadrilateral connecting the two cables.

A l'entrée et à la sortie des stations le chariot roule sur des rails de support par des galets disposés au droit des pinces pour reprendre les réactions des forces de commande des pinces. Sur les tronçons de transfert entre l'entrée et la sortie de la station, le véhicule est supporté par des galets de roulement montés sur la suspente ou au centre du chariot et roulant sur un rail central du type monorail facilitant une circulation sur des tronçons courbes. La propulsion est bien entendu assurée par tout moyen approprié, notamment par une chaîne.At the entrance and exit of the stations, the trolley rolls on support rails by rollers arranged in line with the grippers to resume the reactions of the gripper control forces. On the transfer sections between the entrance and the exit of the station, the vehicle is supported by rollers mounted on the hanger or in the center of the trolley and rolling on a central rail of the monorail type facilitating movement on curved sections . Propulsion is of course provided by any suitable means, in particular by a chain.

Selon un autre développement de l'invention, les mouvements de roulis du véhicule sont limités par une liaison entre les contrepoids de tension des deux câbles. L'équilibre d'un véhicule, qui oscille latéralement en augmentant la flexion de l'un des câbles, est ainsi rétabli automatiquement par une flexion correspondante de l'autre câble, cette liaison étant agencée pour ne-pas entraver des mouvements relatifs lents des contrepoids.According to another development of the invention, the roll movements of the vehicle are limited by a connection between the tension counterweights of the two cables. The balance of a vehicle, which oscillates laterally by increasing the bending of one of the cables, is thus automatically restored by a corresponding bending of the other cable, this connection being arranged so as not to impede slow relative movements of the counterweight.

D'autres avantages et caractéristiques de l'invention ressortiront plus clairement de la description qui va suivre de deux modes de mise en oeuvre de l'invention, donnés à titre d'exemples non limitatifs et représentés aux dessins annexés, dans lesquels :

  • - ta figure 1 est une vue schématique en élévation d'une télécabine selon l'invention ;
  • - la figure 2 est une coupe suivant la ligne II-II de la figure 1 ;
  • - la figure 3 est une vue en plan de la télécabine- selon la figure 1 ;
  • - les figures 4 et 5 sont des vues analogues à celles des figures 1 et 2, illustrant une variante de réalisation de l'invention.
Other advantages and characteristics of the invention will emerge more clearly from the description which follows of two embodiments of the invention, given by way of nonlimiting examples and represented in the appended drawings, in which:
  • - Your Figure 1 is a schematic elevational view of a gondola according to the invention;
  • - Figure 2 is a section along the line II-II of Figure 1;
  • - Figure 3 is a plan view of the gondola- according to Figure 1;
  • - Figures 4 and 5 are views similar to those of Figures 1 and 2, illustrating an alternative embodiment of the invention.

Sur les figures, deux câbles porteurs-tracteurs 10, 12 d'une télécabine s'étendent parallèlement entre deux stations (non représentées) équipées de poulies de renvoi. Les deux câbles 10, 12 constituent deux boucles sans fin à défilement continu disposées à un même niveau horizontal et portant des véhicules ou cabines 14 accouplés en ligne aux câbles, pour circuler en circuit fermé sur les voies aller et retour constituées par les deux boucles de câbles. Dans les stations, les véhicules 14 sont désaccouplés des câbles pour circuler à vitesse réduite sur des rails de transfert à quais d'embarquement et de débarquement des passagers. Les deux câbles porteurs-tracteurs 10, 12 sont entraînés en synchronisme par des moteurs appropriés, par exemple du type décrit dans la demande de brevet précitée. Chaque véhicule 14 comporte une suspente centrale 16, dont l'extrémité libre est articulée sur un axe transversal 18, porté par un chariot 20. Dans l'exemple de réalisation selon les figures 1-3, le chariot 20 comprend un châssis rectangulaire et quatre pinces 22 d'accouplement aux câbles 10, 12 articulées aux quatre coins du châssis. Le chariot 20 est intercalé entre les câbles 10, 12 et les pinces 22 du type standard en saillie latérale, prennent appui sur le dessus des câbles 10, 12 en les enserrant par deux mors, commandés par un levier pivotant 24 et un ressort de fermeture (non représenté). L'ouverture des pinces 22 est provoquée par un abaissement des leviers 24 au passage d'un volet de commande, s'étendant le long de la voie à l'entrée et à la sortie des stations. La réaction de la force de commande est reprise par des galets de roulement 26, disposés au voisinage des pinces 22 sur le chariot 20 et roulant sur des rails de support qui s'étendent dans les zones d'embrayage et de débrayage des pinces 22.In the figures, two carrier-towing cables 10, 12 of a gondola extend parallel between two stations (not shown) equipped with return pulleys. The two cables 10, 12 constitute two endless loops with continuous scrolling arranged at the same horizontal level and carrying vehicles or cabins 14 coupled in line to the cables, to circulate in a closed circuit on the outward and return tracks formed by the two cable loops. In the stations, the vehicles 14 are uncoupled from the cables in order to travel at reduced speed on transfer rails at embarkation and disembarkation platforms for passengers. The two carrier-tractor cables 10, 12 are driven in synchronism by suitable motors, for example of the type described in the aforementioned patent application. Each vehicle 14 has a central hanger 16, the free end of which is articulated on a transverse axis 18, carried by a carriage 20. In the embodiment according to Figures 1-3, the carriage 20 comprises a rectangular frame and four clamps 22 for coupling to the cables 10, 12 articulated at the four corners of the chassis. The carriage 20 is interposed between the cables 10, 12 and the clamps 22 of the standard type projecting from the side, bear on the top of the cables 10, 12 by enclosing them by two jaws, controlled by a pivoting lever 24 and a closing spring. (not shown). The opening of the clamps 22 is caused by a lowering of the levers 24 in the passage of a control flap, extending along the track at the entrance and at the exit of the stations. The reaction of the control force is taken up by rollers 26, arranged in the vicinity of the clamps 22 on the carriage 20 and rolling on support rails which extend in the clutching and disengaging areas of the clamps 22.

De telles télécabines à un ou deux câbles porteurs-tracteurs sont bien connues et il est inutile de décrire plus en détail leur constitution et leur fonctionnement.Such gondolas with one or two carrier cables are well known and it is unnecessary to describe in more detail their constitution and operation.

Selon l'invention, l'écartement des deux câbles porteurs-tracteurs 10, 12 est supérieur au gabarit, en l'occurrence à la largeur 1 du véhicule 14 pour permettre un dégagement du véhicule désaccouplé des câbles 10, 12, par exemple par une déviation vers le bas des câbles par rapport au véhicule dans les stations. Le grand écartement des câbles porteurs 10, 12 assure une bonne stabilité du véhicule 14, dont la suspente peut être raccourcie et se résumer à une tige de liaison entre le véhicule 14 et le chariot 20. Ce dernier est disposé juste au-dessus du toit du véhicule 14 et l'encombrement de l'ensemble chariot 20, véhicule 14 est réduit au maximum. Dans la variante selon les figures 1 à 3, l'axe 18 d'articulation de la suspente 16 est porté par deux chaises verticales 28 solidaires du chariot 20 pour décaler le point d'articulation légèrement vers le haut par rapport au chariot et augmenter la distance du centre de gravité du véhicule 14 à l'axe 18. A l'extrémité 30 de la suspente 16 est fixé rigidement un deuxième chariot 32 à voie étroite, portant quatre galets 34, qui roulent dans les stations sur un ou des rails de transfert à la manière d'un monorail. Ce deuxième chariot 32 est petit, ce qui facilite la circulation sur les voies courbes en station. Il est clair que ce deuxième chariot 32 peut être solidaire ou être constitué par.une partie du chariot principal 20.According to the invention, the spacing of the two carrying cables 10, 12 is greater than the gauge, in this case the width 1 of the vehicle 14 to allow the uncoupled vehicle to be released from the cables 10, 12, for example by a downward deviation of cables from vehicle in stations. The large spacing of the carrying cables 10, 12 ensures good stability of the vehicle 14, the hanger of which can be shortened and boil down to a connecting rod between the vehicle 14 and the carriage 20. The latter is arranged just above the roof of the vehicle 14 and the size of the carriage 20, vehicle 14 assembly is reduced to the maximum. In the variant according to Figures 1 to 3, the axis 18 of articulation of the hanger 16 is carried by two vertical chairs 28 integral with the carriage 20 to offset the point of articulation slightly upward relative to the carriage and increase the distance from the center of gravity of the vehicle 14 to the axis 18. At the end 30 of the hanger 16 is rigidly fixed a second carriage 32 with a narrow track, carrying four rollers 34, which roll in the stations on one or more rails transfer like a monorail. This second carriage 32 is small, which facilitates circulation on the curved tracks in the station. It is clear that this second carriage 32 can be integral or be constituted by a part of the main carriage 20.

Le plancher 36 du véhicule 14 est avantageusement de forme cylindrique à axe coïncidant avec l'axe 18 d'articulation de la suspente 16 afin d'éviter tout frottement sur le sol des stations lors d'une oscillation longitudinale du véhicule 14.The floor 36 of the vehicle 14 is advantageously of cylindrical shape with an axis coinciding with the axis 18 of articulation of the hanger 16 in order to avoid any friction on the ground of the stations during a longitudinal oscillation of the vehicle 14.

Les figures 4 et 5 illustrent une variante de réalisation et les mêmes numéros de repère sont utilisés pour désigner des pièces analogues ou identiques. La suspente 16 est articulée au centre d'une poutre transversale 38 portant à ses extrémités deux longerons 40 avec les galets de roulement 26. L'ensemble poutre 38, longerons 40 et galets 26, constitue un chariot simplifié accolé au toit du véhicule 14. Ce chariot porte dans sa partie centrale le deuxième chariot 32 à voie étroite pour une circulation sur le rail de transfert de la station. D'autres modes de réalisation des chariots de support sont concevables tout en conservant l'avantage d'un emploi d'éléments standard de télécabines et d'un dégagement aisé du véhicule encastré entre les câbles porteurs-tracteurs 10. 12.Figures 4 and 5 illustrate an alternative embodiment and the same reference numbers are used to designate similar or identical parts. The hanger 16 is articulated at the center of a transverse beam 38 carrying at its ends two longitudinal members 40 with the rollers 26. The beam assembly 38, longitudinal members 40 and rollers 26 constitutes a simplified carriage attached to the roof of the vehicle 14. This carriage carries in its central part the second carriage 32 with narrow gauge for circulation on the transfer rail of the station. Other embodiments of the support carriages are conceivable while retaining the advantage of using standard elements of gondola lifts and of easy clearance of the vehicle embedded between the carrier-tractor cables 10. 12.

La longueur du véhicule 14 est de préférence inférieure à sa largeur pour limiter les inclinaisons du véhicule lors d'une concentration des passagers à l'avant ou à l'arrière. La longueur du chariot 20 doit être supérieure au quart de sa largeur pour former un cadre rigide de liaison entre les câbles porteurs-tracteurs 10, 12, qui maintient le synchronisme de déplacement des deux câbles, de la manière décrite dans la demande de brevet précitée.The length of the vehicle 14 is preferably less than its width to limit the inclinations of the vehicle during a concentration of passengers at the front or at the rear. The length of the carriage 20 must be greater than a quarter of its width to form a rigid connection frame between the carrier-tractor cables 10, 12, which maintains the synchronism of movement of the two cables, as described in the aforementioned patent application .

Les mouvements de roulis du véhicule 14 sont limités par une liaison mécanique entre les contrepoids ou tendeurs des deux câbles 10, 12. qui impose des mouvements verticaux identiques des deux câbles. Cette liaison est agencée pour autoriser un réglage initial de la tension de chaque câble.The roll movements of the vehicle 14 are limited by a mechanical connection between the counterweights or tensioners of the two cables 10, 12. which requires identical vertical movements of the two cables. This link is arranged to allow an initial adjustment of the tension of each cable.
