Abstract

A carriage coupling cars to a carrier-hauling rope of a cable-car comprises two grips having protruding parts above the upper face of the rope. A connecting part with a concave running face facilitating the passage of the grips under the compression sheaves extends between the protruding parts.

Description

L'invention est relative à un chariot d'accouplement de charges, notamment de cabines ou de sièges, à un câble aérien d'une installation de transport ayant des balanciers de galets de support et de compression dudit câble, échelonnés le long de la ligne, ledit chariot ayant deux pinces espacées, pour enserrer chacune le câble par une paire de mâchoires, qui chevauchent le câble en faisant une saillie limitée au-dessus de la face supérieure du câble facilitant le passage de la pince sous les galets de compression, ladite saillie étant prolongée, de part et d'autre dans la direction du câble par une piste de roulement pour faciliter l'entrée et la sortie de la pince sous un galet de compression.The invention relates to a load coupling carriage, in particular of cabins or seats, to an overhead cable of a transport installation having pendulums of rollers for supporting and compressing said cable, staggered along the line. , said carriage having two spaced pliers, to each grip the cable by a pair of jaws, which overlap the cable by making a limited projection above the upper face of the cable facilitating the passage of the clamp under the compression rollers, said protrusion being extended, on either side in the direction of the cable by a rolling track to facilitate the entry and exit of the clamp under a compression roller.

Un chariot connu du genre mentionné (voir par exemple le FR-A 2 424 838), comporte une barre flexible d'une épaisseur égale à celle des saillies des pinces, cette barre étant disposée sur la face supérieure du câble enserré par les pinces, dans l'intervalle séparant les deux saillies. On évite ainsi au passage des pinces sous un galet de compression, une retombée du galet, après le franchissement de la saillie de la première pince, suivie d'une remontée imposée par la saillie de la deuxième pince du chariot. La flexibilité de la barre permet à celle-ci de suivre les courbures du câble en restant plaquée sur le câble. Ce dispositif réduit les vibrations et les chocs au passage d'un balancier de compression, mais ce passage reste bruyant et inconfortable.A known carriage of the kind mentioned (see for example FR-A 2 424 838), comprises a flexible bar with a thickness equal to that of the projections of the clamps, this bar being disposed on the upper face of the cable enclosed by the clamps, in the interval between the two projections. This avoids the passage of the clamps under a compression roller, a fall of the roller, after crossing the projection of the first clamp, followed by a rise imposed by the projection of the second clamp of the carriage. The flexibility of the bar allows it to follow the curvatures of the cable while remaining pressed against the cable. This device reduces vibrations and shocks when passing a compression pendulum, but this passage remains noisy and uncomfortable.

La présente invention a pour but de réaliser un chariot perfectionné, dont le passage sous les galets de compression est facilité. Elle part de la constatation que les chocs résultent d'une mise en mouvement ou d'un arrêt d'une pièce, ce choc étant d'autant plus brutal que la masse déplacée et la vitesse sont importantes.The object of the present invention is to produce an improved carriage, the passage of which under the compression rollers is facilitated. It starts from the observation that the shocks result from setting in motion or stopping a part, this shock being all the more brutal as the mass moved and the speed are important.

Le chariot selon l'invention est caractérisé en ce que la piste de roulement, intercalée entre les deux pinces, présente à ses deux extrémités une épaisseur maximale sensiblement égale à celle de ladite saillie pour affleurer au niveau de la saillie au-dessus du câble dans la zone de raccordement à la pince et une forme générale concave orientée vers le haut avec une épaisseur minimale au milieu entre les deux pinces.The carriage according to the invention is characterized in that the raceway, interposed between the two clamps, has at its two ends a maximum thickness substantially equal to that of said projection to be flush with the projection above the cable in the connection area to the clamp and a generally concave shape oriented upwards with a minimum thickness in the middle between the two clamps.

L'emprisonnement d'un tronçon du câble entre les deux pinces du chariot accroît la rigidité de ce tronçon et la forme concave de la piste de roulement compense cette rigidité en présentant au galet de compression une courbure analogue à celle du câble libre. Cette comp ensation est particulièrement intéressante dans le cas d'un chariot à pinces fixées rigidement et reliées par une barre rigide interposée entre les deux saillies, mais elle présente des avantages également pour une barre flexible.The imprisonment of a section of the cable between the two clamps of the carriage increases the rigidity of this section and the concave shape of the raceway compensates for this rigidity by presenting the compression roller with a curvature similar to that of the free cable. This compensation is particularly advantageous in the case of a carriage with clamps rigidly fixed and connected by a rigid bar interposed between the two projections, but it also has advantages for a flexible bar.

La forme concave est concrétisée par une rampe descendante, suivie d'une rampe ascendante. Par un choix approprié de la longueur de ces rampes, en fonction de l'écartement des galets successifs de compression et en combinaison avec les rampes formées par les aiguilles à l'entrée et à la sortie du chariot, il est possible de reconstituer le simple basculement du balancier, dont l'axe reste pratiquement immobile au passage de la pince, couramment utilisé pour une pince unique. L'espacement des deux pinces est avantageusement voisin du double de celui de deux galets successifs.The concave shape is embodied by a descending ramp, followed by an ascending ramp. By an appropriate choice of the length of these ramps, depending on the spacing of the successive compression rollers and in combination with the ramps formed by the needles at the entry and exit of the carriage, it is possible to reconstruct the simple tilting of the pendulum, the axis of which remains practically stationary when the clamp passes, commonly used for a single clamp. The spacing of the two clamps is advantageously close to twice that of two successive rollers.

L'invention est essentiellement applicable à des transporteurs, monocâble du type télécabine ou télésiège débrayable, mais elle est utilisable pour des pinces fixes ou d'autres installations.The invention is essentially applicable to conveyors, a single cable of the detachable gondola or chairlift type, but it can be used for fixed clamps or other installations.

Sur les figures, un câble 10 d'une télécabine ou d'un télésiège débrayable s'étend entre deux stations, dans lesquelles les cabines ou sièges sont désaccouplés du câble 10 pour un débarquement et/ou embarquement à vitesse lente ou nulle. Chaque cabine ou siège est fixé par une suspente 12 à un chariot 14 d'accouplement au câble 10, porteur-tracteur. Le châssis 16 du chariot 14 porte deux pinces 18, 20 enserrant le câble 10 en deux points espacés, lorsque le chariot 14 est accouplé au câble 10. Les pinces 18, 20 sont identiques, par exemple du type décrit dans le brevet français 2.497.750 dont seuls les principaux éléments sont rappelés. Chaque pince comprend une paire de mâchoires 22, 24 à axe d'articulation 26, disposé au-dessus du câble 10, enserré entre les mâchoires. La mâchoire fixe 22 est solidaire du châssis 16, tandis que la mâchoire mobile 24 est portée par un levier de commande 28, s'étendant du côté opposé de l'axe 26. Le levier 28 est sollicité en position de fermeture de la pince par un ressort 30 et est commandé par un galet 32, coopérant au passage du chariot 14 avec un rail de commande (non représenté) pour l'ouverture de la pince. Les mâchoires 22, 24 sont enfourchées sur le câble 10, affleurant ou en faible retrait de la face inférieure du câble 10 pour un passage sans contact sur des galets de support du câble 10. Les mâchoires 22, 24 forment au niveau de l'axe 26 une saillie 34 au-dessus de la face supérieure du câble 10. Entre les saillies 34, 34a des deux pinces 18, 20 s'étend une barre de liaison 36, dont la face 38 opposée au câble 10 constitue une piste de roulement. Dans l'exemple illustré par les figures, les pinces 18, 20 sont rigidement fixées au châssis 16 et la barre de liaison 36 est rigide et fixée aux saillies 34, 34a par ses extrémités. Des aiguilles 40, 42 en forme de rampe prolongent les saillies 34, 34a du côté opposé à la barre de liaison 36. Le chariot 14 comporte des galets 44 de roulement sur des rails de transfert dans les stations, après désaccouplement du câble 10.In the figures, a cable 10 of a detachable gondola or chairlift extends between two stations, in which the cabins or seats are uncoupled from the cable 10 for disembarking and / or boarding at low or zero speed. Each cabin or seat is fixed by a hanger 12 to a carriage 14 for coupling to the cable 10, carrier tractor. The chassis 16 of the carriage 14 carries two clamps 18, 20 enclosing the cable 10 at two spaced points, when the carriage 14 is coupled to the cable 10. The clamps 18, 20 are identical, for example of the type described in French patent 2,497. 750 of which only the main elements are recalled. Each clamp comprises a pair of jaws 22, 24 with a hinge pin 26, disposed above the cable 10, sandwiched between the jaws. The fixed jaw 22 is integral with the chassis 16, while the movable jaw 24 is carried by a control lever 28, extending on the opposite side of the axis 26. The lever 28 is biased in the closed position of the clamp by a spring 30 and is controlled by a roller 32, cooperating in the passage of the carriage 14 with a control rail (not shown) for the opening of the clamp. The jaws 22, 24 are straddled on the cable 10, flush or in slight withdrawal from the underside of the cable 10 for a contactless passage over the cable support rollers 10. The jaws 22, 24 form at the axis 26 a projection 34 above the upper face of the cable 10. Between the projections 34, 34a of the two clamps 18, 20 extends a connecting bar 36, the face 38 opposite the cable 10 constitutes a raceway. In the example illustrated by the figures, the clamps 18, 20 are rigidly fixed to the chassis 16 and the connecting bar 36 is rigid and fixed to the projections 34, 34a by its ends. Needles 40, 42 in the form of a ramp extend the projections 34, 34a on the side opposite to the connecting bar 36. The carriage 14 comprises rollers 44 for rolling on transfer rails in the stations, after uncoupling of the cable 10.

En se référant plus particulièrement à la figure 4, on voit que, lors d'un passage du chariot 14 sous un train 46 de balanciers de compression, l'aiguille 40 soulève le premier galet du premier balancier élémentaire 50 pour l'amener au niveau de la saillie 34, ce galet 48 roulant ensuite sur la piste 38 de la barre 36 avant de franchir la saillie 34a et de redescendre sur l'aiguille 42. Simultanément, l'aiguille 40 engage le deuxième galet 52 du premier balancier élémentaire 50, puis le premier galet 54 du deuxième balancier élémentaire 56 et le deuxième galet 58 de ce deuxième balancier et ainsi de suite, d'une manière bien connue des spécialistes. Les deux balanciers élémentaires 50, 56 sont articulés par des axes 64, 66 sur un balancier principal 60, monté à pivotement en son centre 62.Referring more particularly to FIG. 4, it can be seen that, when the carriage 14 passes under a train 46 of compression rockers, the needle 40 lifts the first roller from the first elementary rocker 50 to bring it to the level of the projection 34, this roller 48 then rolling on the track 38 of the bar 36 before crossing the projection 34a and descending on the needle 42. Simultaneously, the needle 40 engages the second roller 52 of the first elementary balance 50, then the first roller 54 of the second elementary balance 56 and the second roller 58 of this second balance and so on, in a manner well known to specialists. The two elementary pendulums 50, 56 are articulated by axes 64, 66 on a main pendulum 60, pivotally mounted at its center 62.

Selon l'invention, la barre de liaison 36 présente une épaisseur égale à celle des saillies 34, 34a à ses extrémités pour éviter une solution de continuité, la partie centrale de la barre 36 étant plus mince ou d'épaisseur nulle, de façon à créer une surface de roulement 38 concave ou creuse qui coopère avec les galets de compression. L'ensemble est agencé de telle manière que les deux galets d'un même balancier ne sont jamais soulevés ou abaissés en même temps au passage du chariot, l'un roulant avantageusement sur une piste descendante lorsque l'autre roule sur une piste ou rampe montante. Le point d'articulation 64, 66 du balancier 50, 56 reste ainsi sensiblement immobile, le mouvement se limitant à un pivotement du balancier. Cet effet de compensation résulte de la longueur des aiguilles 40, 42 et de celle de la barre de liaison 36 par rapport à l'écartement de deux galets de compression successifs. Sur la figure 5 on voit que le deuxième galet 52 va amorcer le mouvement descendant sur la piste 38 au moment où le premier galet 48 aborde l'aiguille 42. La longueur de cette aiguille 42 est sensiblement égale à l'écartement entre les galets 48, 52. D'une manière analogue l'espacement des saillies 34, 34a est voisine du double de cet écartement des galets 48, 52. Pour illustrer le mouvement limité des axes 64, 66, 62 des balanciers 50, 56, 60, le chariot 14 est supposé immobile, les balanciers se déplaçant dans la direction du câble 10 et on a représenté sur la figure 5 la trajectoire des axes 64, 66, 62 en trait plein. a titre de comparaison la trajectoire correspondante, dans le cas d'une barre de liaison 36 droite, est représentée en pointillés.According to the invention, the connecting bar 36 has a thickness equal to that of the projections 34, 34a at its ends to avoid a solution of continuity, the central part of the bar 36 being thinner or of zero thickness, so as to create a concave or hollow rolling surface 38 which cooperates with the compression rollers. The assembly is arranged in such a way that the two rollers of the same pendulum are never raised or lowered at the same time when the carriage passes, one advantageously rolling on a descending track when the other is rolling on a track or ramp rising. The articulation point 64, 66 of the balance 50, 56 thus remains substantially stationary, the movement being limited to a pivoting of the balance. This compensation effect results from the length of the needles 40, 42 and that of the connecting bar 36 relative to the spacing of two successive compression rollers. In Figure 5 we see that the second roller 52 will initiate the downward movement on the track 38 when the first roller 48 approaches the needle 42. The length of this needle 42 is substantially equal to the spacing between the rollers 48 , 52. Similarly, the spacing of the projections 34, 34a is close to twice this spacing of the rollers 48, 52. To illustrate the limited movement of the axes 64, 66, 62 of the pendulums 50, 56, 60, the carriage 14 is assumed to be stationary, the pendulums moving in the direction of the cable 10 and FIG. 5 shows the trajectory of the axes 64, 66, 62 in solid lines. for comparison, the corresponding trajectory, in the case of a straight link bar 36, is shown in dotted lines.

La figure 6, analogue à la figure 5, montre le passage du chariot 14 sous un balancier de compression chargé, imposant au câble 10 une courbure vers le bas. La courbure de la barre de liaison 36 compense dans ce cas en partie la rigidité du chariot 14 et permet de limiter les amplitudes de déplacement des axes 64, 66, 62 des balanciers en simulant une courbure du chariot 14, qui suit celle du câble 10. Il est clair que les mouvements limités, engendrés par le passage du chariot sous les balanciers de compression, facilitent ce passage et limitent les vibrations, qui sont à l'origine d'usures et de bruits.Figure 6, similar to Figure 5, shows the passage of the carriage 14 under a loaded compression rocker, imposing on the cable 10 a downward curvature. The curvature of the connecting bar 36 in this case partially compensates for the rigidity of the carriage 14 and makes it possible to limit the amplitudes of movement of the axes 64, 66, 62 of the pendulums by simulating a curvature of the carriage 14, which follows that of the cable 10 It is clear that the limited movements generated by the passage of the carriage under the compression pendulums facilitate this passage and limit the vibrations, which are the cause of wear and noise.

L'invention peut être appliquée à un chariot, équipé de pinces articulées sur le châssis, pour suivre les courbures du câble, la barre de liaison étant dans ce cas flexible. La compensation plus faible n'est pas négligeable et permet d'accroître le confort des passagers. La liaison courbe selon l'invention peut être utilisée pour toute attache présentant deux saillies ou protubérances espacées le long du câble.The invention can be applied to a trolley, equipped with clamps articulated on the chassis, to follow the curvatures of the cable, the connecting bar in this case being flexible. The lower compensation is not negligible and increases passenger comfort. The curved connection according to the invention can be used for any fastener having two protrusions or protuberances spaced along the cable.

L'invention est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit et elle s'applique à d'autres types de pinces.The invention is of course in no way limited to the mode of implementation more particularly described and it applies to other types of pliers.
