Definitions

  • the present invention relates to a security device, intended to prevent a traction and / or suspension cable of a transport system with drive and suspension by cable out of a guide and suspension pulley.
  • the purpose of the present invention is to provide a solution allowing this risk to be eliminated, at least in part.
  • the subject of the present invention is a device safety device, intended to prevent a traction cable and / or suspension of a driven transport system and cable suspension from a guide pulley and suspension, as defined by claim 1. Others peculiarities of this device are described in the description which will follow and are the subject of the dependent claims.
  • the safety device illustrated in Figures 1 to 3 has a vertical frame 1 at the top of which a shaft 2 is pivotally mounted about a horizontal axis.
  • This shaft 2 door on one side of the vertical frame 1, two arms of radial retainers 3, 4, forming an angle of approximately 90 ° between them and on the other side of the vertical frame 1, a circular cam 5, against which a feeler roller 6 is pressed in the direction of the pivot axis of the shaft 2, by a spring 7.
  • the roller probe 6 is itself pivotally mounted around a rod 8 with an axis parallel to that of shaft 2 and integral with the end of a slide 9 mounted sliding in a casing 11, fixed to the frame vertical 1 by screws 12.
  • the housing 11 has the shape of a hollow rectangular parallelepiped constituted by several plates 11b assembled by screws 11a.
  • the spring 7 is disposed between the bottom of this casing 11 and a socket 13 fixed in the slide 9.
  • Figure 3 illustrates the cam circular 5 in the stable position of the pivot shaft 2 and arms 3 and 4, corresponding to the position of the arms illustrated by Figures 1, 4 and 6.
  • this stable position corresponds to the place where the circular cam 5 has a concave curvature 5a, the radius corresponds to that of the feeler roller 6.
  • the circular cam On both sides of this concave part 5a, the circular cam has two convex curves 5b symmetrical about a passing line by the axis of the pivot shaft 2 and the middle of the concave curvature 5a.
  • the distance between each of these convex curvatures 5b of the pivot axis of the shaft of pivot 2 grows away from the concave curvature 5a, so that the pressure exerted on this circular cam 5 by the spring 7 by means of the feeler roller 6 created on this circular cam 5 a torque tending to bring it constantly in the position illustrated in Figure 3, as soon as it is angularly moved away from this stable position.
  • each retaining arm radial 3, 4, (only arm 3 is shown in this figure 2) has a cylindrical core 3a fixed to a hub 2a integral with shaft 2 and a tubular element covered with elastomer 3b is mounted to rotate freely around the core cylindrical 3a.
  • This tubular element 3b is retained axially on the cylindrical core 3a by a retaining member 3c maintained by a 3d screw.
  • Figure 4 illustrates the safety device described above associated with a yoke of pulleys 13 carrying two pairs of guide pulleys 14, of which only one pair is shown, as well as a traction and / or suspension cable 15, to which is attached a fixing member 16 of a transport (not shown).
  • This transport device can be of any type with drive and suspension by cable, such as a ski lift, chairlift, gondola, a cable car, which is driven by cable 15 in the direction of arrow F.
  • FIG. 4 shows this fixing member 16 located at upstream of the radial retaining arm 3.
  • this arm 3 is adjacent to a cheek of the first pulley 14, preventing thus any lateral outlet of the cable 15.
  • the tubular part 3b of this radial retaining arm 3 with its elastomeric coating allows it to be rotated around the core 3a by contact with the pulley cheek 14.
  • the trajectory described by the radial retaining arms 3, 4 is located in a plane adjacent to the cheek of a pulley 14 opposite to that turned towards frame 1 and therefore also adjacent to the cable path 15, whatever the angular position of these arms 3, 4 at during the passage of a fastener 16, there is constantly at least one radial retaining arm 3, 4 of which a part is located at a level lower than that of cable 15, thus retaining this laterally.
  • the safety device according to the invention is constantly in action, even during passage of the fastening member 16 of a vehicle to the cable.
  • Elastic return means could also be for example formed by a spiral spring pre-armed, one end of which is secured to frame 1 and the other of the tree 2.
  • a spring of pre-armed flexion carrying the feeler roller 6 and the respective ends would be integral with the two arms of retained 3, 4.
