Definitions

  • the invention relates to a mechanical rope derailment protection for preventing lateral derailment of a rope running or resting on a rope of a cable car having support and / or hold-down rollers according to the preamble of claim 1.
  • the cable guides on the support or hold-down rollers are based on the fact that the roller profile (feed groove and lateral metal roller board) ensure a narrowly limited degree of derailment protection.
  • the object of the present invention as a safety device is to ensure protection against lateral derailment for all conceivable causes, such as cross winds, column displacements, assembly errors, swings and rope vibrations.
  • the protective device should function in all cases and be usable in all systems and should not pose any additional risk in the event of defects in its construction.
  • the locking member limits the lateral positional deviation of the rope on the reel and prevents the rope from escaping sideways. Only when passing a driving device, the guide rail connected to the locking member is briefly moved away from the rope by the cable clamp to such an extent that the cable clamp and thus the driving device can pass. This actuation is bumpless. The device then returns to its basic position. During the brief release of the locking member from the basic position, there is no risk of derailment with regard to the construction of the rope clamp, the rope rigidity and the inertia of the rope. In the event of a blockage, for example due to icing, etc., the locking device is inevitably released by the approaching rope clamp by pushing it away from the rope.
  • Fig. 1 shows the rope 7, which runs on a roller 6.
  • the construction according to the invention is supported by a cantilever arm 3 which is mounted on the roller 6 or roller battery.
  • the locking members 1 are preferably arranged on the cantilevered end of the cantilever arm 3 pivotably mounted in the region of the rollers 6 or roller battery.
  • the cantilever arm 3 with the locking member (s) 1 grips the rope 7 from above or below.
  • the cantilever arm 3 is rigidly connected to a guide rail 2 and has two vertically arranged locking members which, in the illustrated basic position of the derailment protection, comprise the rope 7 from above in such a way that it can only escape from its desired position to a limited extent, and thus the Cannot leave role 6.
  • the lateral positional deviation of the rope on the reel can also be limited on one side only by a vertical locking member.
  • Fig. 2 shows the derailment protection according to the invention when passing a rope clamp 5.
  • the passing rope clamp 5 lifts the guide rail 2 and the locking members 1 rigidly connected thereto, whereby the mechanical locking device is temporarily released and the rope clamp 5 can pass.
  • the risk of derailment is insignificant, since the rope pressure on the roller 6, which has a stabilizing effect, increases considerably when the driving means approaches.
  • the cantilever arm 3 After passing through the cable clamp, the cantilever arm 3 returns to the basic position, in which the derailment protection is effective, by its own weight or by spring force or a magnetic force.
  • the pivoting movement of the cantilever arm 3 is limited by the arrangement of two stops 4 ".
  • the cantilever arm only has to be pivotable to such an extent that an unimpeded passage of the cable clamp is possible. A deflection beyond the necessary pivoting range is achieved by a Stop 4 "prevents the second stop 4" from defining the basic position.
  • the position of the basic position, in which the derailing block is in operation can be arranged by arranging a roller 4 'which is mounted on the projecting end of the guide rail 2 above the cable 7 and can be rotated about a horizontal axis
  • the return to the basic position, in which the derailment protection acts, and its maintenance can be ensured in particular by the weight of the construction or / and additionally by spring forces 4 ′′ or magnetic forces.
  • the design of the guide rail 2 with curved ends ensures a smooth operation of the derailment protection by the cable clamp 5.
  • the symmetrical design of the curved guide rail 2 allows a function for both directions of travel if this is necessary.
