Definitions

  • the invention relates to a cable car with derailment protection to prevent lateral Derailment of a resting or running rope guided on support and / or hold-down rolls according to the preamble of claim 1.
  • Cable cars of this type have become known from CH-A-360 704.
  • this cable car is one on both the entry and the exit side of the reel that guides the rope provided the rope encompassing fork, the two forks by a hinge mechanism are connected, which holds one of the two forks in the operating position in which the fork grips the rope while the other fork is lifted out of the area of the rope.
  • the Running the rope clamp into the area of the rope pulley encompasses the first in the path of the rope clamp located fork the rope and is from the operating position by the incoming rope clamp lifted, while at the same time the fork located on the outlet side in the area of the rope is pivoted so that this fork now provides rope derailment protection.
  • Cable derailment protection has the disadvantage that it does not allow a return trip of the driving equipment, because in this case the return moving rope clamp located on the inlet side of the rope pulley located fork could not happen.
  • the cable guides on the support or hold-down rollers are based on all known systems insist that the roller profile (feed groove and lateral metal roller board) is a narrowly limited one Ensure a level of protection against derailment.
  • the object of the present invention as a safety device is to protect against lateral derailment for all conceivable causes, such as cross wind, To ensure column displacements, assembly errors, swings and rope vibrations.
  • the Protective device should in all cases, including when the driving equipment is returned work and be usable with all systems and no additional risk in the case of Include defects in their construction.
  • the invention solves this problem by the features of the characterizing part of the Claim 1.
  • the locking member limits the lateral positional deviation of the rope on the reel and prevent the rope from escaping sideways. Only when passing a vehicle the guide rail connected to the locking member is temporarily so far by the cable clamp moved away from the rope that the rope clamp and thus the driving equipment can pass. This Operation is bumpless. The device then returns to its basic position back. During the short-term release of the locking element from the basic position With regard to the construction of the rope clamp, the rope rigidity and the inertia of the rope no risk of derailment. In the event of a blockage, for example due to ice formation, the Locking device inevitably released by the approaching rope clamp by removing it from the rope is pushed away.
  • Fig. 1 shows the rope 7, which runs on a roller 6.
  • the construction according to the invention is carried by a cantilever arm 3, which is mounted on the roller 6 or roller battery.
  • the locking members 1 are preferably at the projecting end of the roller 6 in the region or roller battery pivotally mounted cantilever 3.
  • the cantilever arm 3 engages with the Locking element (s) 1 the rope 7 from above or below.
  • the cantilever 3 stands with one Guide rail 2 in rigid connection and has two vertically arranged locking members the rope 7 from above in the illustrated basic position of the derailment protection include that it can only escape to a limited extent from its target position, and thus cannot leave role 6.
  • the lateral positional deviation of the rope on the reel can be limited only on one side by a vertical locking member.
  • Fig. 2 shows the derailment protection according to the invention when passing a rope clamp 5.
  • Die Passing rope clamp 5 lifts the guide rail 2 and the rigidly connected Locking members 1, whereby the mechanical locking device is temporarily released and the cable clamp 5 can pass. During this brief unlocking is the The risk of derailment is insignificant, since the rope pressure increases when the driving equipment approaches the role 6, which has a stabilizing effect, increases significantly.
  • the cantilever arm 3 After passing the rope clamp the cantilever arm 3 reaches by its own weight or by spring force or a magnetic Force back to the basic position in which the derailment protection is effective.
  • the pivoting movement of the cantilever arm 3 is due to the arrangement two stops 4 '' limited.
  • the cantilever only has to be pivoted so far that a free passage of the rope clamp is possible. A deflection over the necessary Swivel range beyond is prevented by a stop 4 '', the second stop 4 '' defines the basic position.
  • the position of the home position in which the derailment lock is in operation is also specified become.
  • the return to the position in which derailment protection works and theirs Maintenance can in particular by the weight of the structure or / and can also be ensured by spring forces 4 '' 'or magnetic forces.
  • the design the guide rail 2 with curved ends ensures smooth operation of the Protection against derailment through the rope clamp 5.
  • the symmetrical design of the curved Guide rail 2 allows a function for both directions of travel if this is necessary.
