Definitions

  • the invention relates to a disengageable clamp for coupling a load to a carrier-tractor cable of an overhead cable transport installation, comprising a clamp body extending transversely on one side of the cable, in position coupled to the latter, and carrying an articulation of a load support hanger, a cable clamping jaw, constituted by a fixed jaw carried by the clamp body and a movable jaw articulated on the fixed jaw, a lever control, which is integral with the movable jaw and extends the latter by extending and struggling in a first plane containing the clamp body, to control the opening and closing of the jaw, and a pair of compression springs to rod placed symmetrically on either side of said first plane and urging the control lever in the closed position of the jaw.
  • a known clamp of the kind mentioned (EP-A-0 056 919) is particularly simple and can remain in line overnight without risk of blockage by ice or frost.
  • This clamp has springs interposed between the ends, on the side opposite the fixed jaw, of the clamp body and of the control lever. This arrangement implies a robust and bulky structure of the clamp, adapted to the large forces to be transmitted.
  • the present invention aims to allow the realization of a disengageable clamp of simple and compact structure.
  • the clamp according to the invention is characterized in that one of the ends of the springs is anchored in the vicinity of the end of the control lever, opposite the movable jaw, that the other end of the springs is anchored near the fixed jaw, that the two springs extend in a second plane, which is perpendicular to the first plane and is inclined relative to the clamp body and that the distance in said second plane between the points the ends of the springs on the side of the fixed jaw is greater than that on the side of the control lever.
  • the anchor point of the springs is transferred near the fixed jaw and the articulation of the hanger and it is easy to see that the forces are concentrated in this zone which is arranged accordingly.
  • the two springs are anchored on the side of the jaw fixed to a cross member, which carries the support and guide rollers of the clamp.
  • the clamp is uncoupled from the cable at the entrance to a station and the rollers roll on a transfer rail.
  • the rollers and the anchor points of the springs are in the vicinity of the ends of the cross member and the latter is interposed between the fixed jaw and the articulation of the hanger.
  • the clamp advantageously comprises a third roller mounted for rotation on the end of the clamp body, opposite the fixed jaw.
  • the control lever carries at its end opposite to the movable jaw a control roller, which cooperates at the entrance to a station with a control rail for opening the clamp to uncoupling the clamp from the cable.
  • a rail disposed at the outlet, controls the re-coupling of the clamp to the cable in a manner well known to specialists.
  • the distance between the anchoring points of the springs, on the side of the fixed jaw, is greater than the gauge of the articulation of the hanger, which can thus be adjacent to the cross member while being framed by the two springs.
  • the anchoring points of the springs on the side of the fixed jaw are substantially at the level of the clamp body and the springs extend upwards above the clamp body while being doubly inclined relative to the latter. These inclinations influence the action of the springs on the control lever and allow modulation of the characteristics of these springs.
  • the drive of the uncoupled clamp of the cable in the stations is preferably carried out by sets of wheels tires, which engage a friction track arranged above the cross member which carries the support rollers.
  • a disengageable clamp has an elongated body 10, which extends, in the coupled position of the clamp to the cable 9, transversely to the cable.
  • the body 10 carries an articulation 11 of a hanger 12 and it is extended by a pair of jaws 13,14 forming a cable clamping jaw 9, one of the jaws being fixed and the other movable 14 being articulated on an axis 15 carried by the body 10.
  • the axis 15 extends parallel above the cable 9.
  • the movable jaw 14 is shaped at the end 16 d 'a control lever 17, which extends and can be struggled, during a pivoting on the axis 15, in a first plane containing the clamp body 10 and corresponding to the plane of Figure 1.
  • At the end 18, opposite the movable jaw 14, of the lever 17 is fixed an axis 19 of rotation of a control roller 20.
  • the clamp body 10 carries three rollers 21,22,23 for supporting and guiding the clamp uncoupled from the cable 9 and likely to roll on rails in stations.
  • One 21 of the rollers is rotatably mounted on the end of the clamp body 10, opposite the fixed jaw 13 and the other two 22,23 are fixed to the ends 24,25 of a crosspiece 26 carried by the clamp body 10.
  • the cross member 26 is interposed between the fixed jaw 13 and the articulation 11 and it extends in the direction of the cable 9. Above the cross member 26 is arranged a friction track 27, capable of cooperating with wheels pneumatic for the gripper drive in the stations.
  • pliers are well known and there is no need to describe them in more detail.
  • the control lever 17 is biased in the cable tightening position 9, shown in solid lines in the figures, by a pair of compression coil springs 28, 29, interposed between the control lever 17 and the clamp body 10.
  • the two springs 28, 29 are arranged symmetrically on either side of the first plane, defined by the control lever 17 and the gripper body 10, and they extend in a second plane perpendicular to the first and inclined relative to the body. of clamp 10.
  • the upper ends 30, 31 of the springs 28, 29 are anchored by spherical articulations 37 to a transverse arm 32, fixed to the end 18 of the control lever 17.
  • the lower ends 33, 34 springs 28, 29 are anchored in the vicinity of the ends 24, 25 of the cross-member 26 by spherical joints 37 and arms 35, 36.
  • the anchoring points of the lower ends 33, 34 are substantially at the level of the clamp body 10 and their spacing is sufficient to free the housing and pivoting template of the hanger 12 and its articulation 11.
  • the spacing of the points d anchoring of the upper ends 30, 31 is appreciably weaker and it is easy to see that the springs 28, 29 are both inclined in the first and in the second plane. This oblique arrangement allows a bringing together of the active parts of the clamp subjected to significant forces, in this case the jaws 13, 14, the hanger 12, the cross member 26 and the lower ends 33, 34 of the springs 28, 29.
  • the structure of the clamp is particularly compact, while retaining a clearance from the moving parts which are not likely to be blocked by ice or frost.
  • the double inclination of the springs 28, 29 modifies the component of the force of the springs acting on the control lever 17 and this inclination varies with the pivoting of the control lever 17 as shown in dotted lines in the figures.
