Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the concave shape is embodied by a descending ramp, followed by an ascending ramp.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
