Definitions

  • the invention relates to an overhead cable transport installation according to the preamble of claim 1.
  • the document FR-A-2 172 615 describes an installation of the type mentioned, in which the vehicles are uncoupled from the cable at the entrance to the station, by opening and disengaging the cable clamp, to allow circulation at reduced speed of the vehicles on a transfer circuit and embarkation and / or disembarkation of passengers at a stationary or low speed vehicle.
  • Each clamp has a tension spring, which is incorporated in the clamp body above the hanger and which acts on a pivoting lever carrying at its end the movable jaw of the clamp.
  • the movable jaw is arranged on the side of the clamp body.
  • the vehicles are sheltered on storage rails in the stations, so as not to expose the clamps to frost or ice.
  • the arrangement of the storage rails is complicated and expensive and the reliability of the tension spring is uncertain.
  • the only movable part of the clamp in this case the movable arm, performs a pivoting movement and the significant leverage makes it possible to exert significant clamping forces on the jaws or to break the ice.
  • the simplicity of the clamp reduces the risk of faulty operation or blockage of the clamp.
  • the spring is fully released and there is no risk of it getting caught in the ice.
  • the document FR-A-2 343 636 relates to a clamp actuated by a toggle mechanism on which the weight of the cabin acts.
  • a spring arranged approximately vertically, laterally to the hanger, maintains a safety lock in the locking position of the toggle.
  • a spring for closing the gripper with a large stroke attacks the end of the movable arm in the form of a bent lever and this spring is advantageously arranged vertically parallel to the hanger and outside.
  • the movable jaw of the clamp cooperates with the internal lateral face of the cable, penetrating into the groove of the return pulley, so as to facilitate the passage of the clamp on this latter pulley and to avoid any risk of opening of the clamp during of this passage.
  • a cable 10 of a single-cable air transport installation in particular of a chairlift or gondola, is driven in continuous travel passing through the stations 13 on pulleys 11 of return with vertical axis, one of which is driving .
  • the loads in this case the seats or cabins 15, which will subsequently be considered as seats, are fixed to the cable at regular spacing.
  • Each seat of which only the upper part of the hanger 12 is visible in FIG. 1, is coupled to the cable by a clamp 14 of the disengageable type to allow opening of the clamp in the stations and embarkation or disembarkation at the stop or at low speed seats detached from the cable at a platform 17 placed after or possibly before the return pulley 11.
  • the clamp 14 comprises a body 16 extending, in position coupled to the cable 10, transversely and on the side opposite to the side of the cable cooperating with the return pulley in the stations.
  • the body 16 carries an articulation 18 of the hanger 12 and three rollers 20 capable of cooperating with support rails in the stations.
  • the body 16 is extended by a pair of jaws 22, 24 forming a cable clamping jaw 10, one 24 of the jaws being fixed and the other 22 articulated on an axis 26 carried by the body 16. In the clamping position of the cable 10 by the jaws 22, 24, the axis 26 extends parallel and above the cable 10.
  • the movable jaw 22 is disposed on the side of the cable 10 opposite to that of the body 16 and it encloses a length of the cable 10 lower than that enclosed by the fixed jaw 24.
  • the movable jaw 22 is carried by the end of a movable arm 28, which extends on the side opposite the axis 26 in a direction substantially parallel to the body 16 and leads to its opposite end 30 an axis 32 of articulation of a control roller 34.
  • the mobile arm 28 seen in projection on a vertical plane, is bent at right angles to the articulation 26 to form a bent lever, and, seen in plan, is divided into two branches 36, 36 ', bypassing the articu lation of the body 16.
  • the clamp 14 constitutes a pincer with two arms 16, 28 articulated at 26 and whose ends are shaped as jaws 22, 24, the control force applied to the end 30 of the movable arm 28 being multiplied by the significant ratio of the lifting arms to tighten the cable 10.
  • the tightening and loosening of the jaws 22, 24 is controlled by a substantially vertical movement of the end 30 of an amplitude multiple of that of displacement of the movable jaw 22.
  • the jaws 22, 24 are flush with the base of the cable 10 in the clamped position to allow passage on the rollers 38 for supporting the cable 10 and have a slight projection on the upper part of the cable, which does not hamper passage under compression rollers. Needles (not shown) advantageously extend the fixed jaw 24 to facilitate passage.
  • Such arrangements are well known to specialists as well as the shape of the part 40 of the body 16 and of the part 42 of the movable arm 28 adjacent to the jaw 24, releasing a template for the passage of the rollers.
  • the end 30 of the movable arm 28 carries on the side opposite the roller 34, in this case downwards, an axis 44 of articulation with limited movement of a cup 46 for supporting two coiled springs 48, 50 coaxial , which pass through the end of the body 16 with a large clearance shaped as a ring 52.
  • the opposite end of the springs 48, 50 bears on a cup 54 fixed to the ring 52 of the body 16 of the clamp by a stirrup 56.
  • the springs 48, 50 extend in an almost vertical direction, parallel to the hanger 12 and they exert on the movable arm 28 a force tending to pivot the arm 28 in the closing direction of the clamp 14.
  • the clamp according to the invention operates as follows:
  • the cable 10 drives the clamp 14 and the load carried by the hanger 12 passing over the support rollers 38 and compression.
  • the jaws 22, 24 are biased in the clamping position by the springs 48, 50 whose force is multiplied by the ratio of the lever arms.
  • the rollers 20 engage on fixed rails (not shown) for supporting the clamp 14 while the roller 34 approaches a cam (not shown) imposing on it a displacement downwards against the force of the springs 48, 50.
  • the pivoting resulting from the movable arm 28 causes the jaws 22, 24 to open, separating the clamp 14 from the cable 10.
  • the seat can then be braked or stopped to facilitate disembarking or boarding while the cable 10 remains in motion, moving between the open jaws 22, 24 or below the latter if the clamp 14 has been released by lifting.
  • the re-coupling is carried out by acceleration of the clamp 14 by any appropriate means and reclosing of the jaws 22, 24 as soon as the roller 34 leaves the cam.
  • the clamp 14 passes over the end pulley with a vertical axis, the mobile jaw 22 is wedged between the cable 10 and the pulley and the curvature of the cable 10 does not tend to open the jaws 22, 24.
  • the short length of the mobile jaw 22 facilitates the passage.
  • a plate 57 On the top of the clamp is fixed a plate 57 forming a wheel track (not shown) for driving the clamp on the transfer rails of the stations.
