Definitions

  • the invention relates to a cable lift.
  • a cable elevator typically includes an elevator car suspended from one of the two strands of a cable which, passed over an overhanging pulley the technical sheath in which the cabin circulates, has its other strand which supports a counterweight.
  • the pulley is then locked in rotation on a driven shaft in rotation by a motor placed at the end of the shaft.
  • the diameter of the pulley must be large so that the contact surface between the pulley groove and cable is sufficient to prevent cable slippage in the pulley groove.
  • the counterweight develops a force opposite to that produced by the cabin and therefore limits the load to train.
  • the load to be moved is then equal to the differential between the weight of the cabin with passengers and the weight of the counterweight.
  • the torque of the motor which drives this pulley via the shaft depends on the load to be moved and, more precisely, the load differential, but also the diameter of the pulley.
  • the engine torque must therefore be relatively high.
  • a brake in particular a safety brake.
  • This space is generally called technical room or machinery.
  • the toothed wheels carry out, with the racks, the displacement and the cabin guidance.
  • the brake is then mounted on the motor drive shaft carried by the top of the cabin.
  • Such a device is very noisy.
  • the wheels are mounted so that they form the jaws of pliers.
  • the invention proposes a solution to remedy in particular the aforementioned drawbacks.
  • the pulley is carried by a tree located above the hopper.
  • the cabin is generally guided in translation in the hopper. It is likewise the counterweight.
  • the cabin is carried by a support 100 in the form of a console called commonly arch 100.
  • This arch 100 has two lateral rails 101 cooperating with vertical guides 9.
  • Figure 2 shows a cross section showing this arch, the slides 101 and the vertical guides 9 in the shape of a Tee.
  • roller 102 for guiding the cabin then rests on the rear of the guide surface so that this roller constitutes the pivot point of the cabin.
  • the bottom of the cabin therefore approaches the tacking guide surface thus the strand leading from the means 6 for moving the cabin.
  • two means 6 are used, each cooperating with a guide surface.
  • the width or the sum of the widths of the driving strands of the belts drive as well as the length of the leading strands determines the surface in contact with the guide.
  • This surface in contact with the force applying the so-called leading strands on the guide partly determines the grip for driving the cabin.
  • the supporting materials must also be taken into account. the other.
  • point 10 cable anchorage of the cabin is offset from the vertical axis passing through the center G of gravity of the cabin so that a vertical force is exerted P but also a force F oriented towards the vertical guide.
  • Such a cabin drive device makes it possible to reduce the size of the engine because the driving belt drive torque may be lower.
  • the displacement means 6 is located under the cabin.
  • the displacement means is located at the above the roof of the cabin and is applied to the rear of the guide.
  • the safety brake (not shown) will be mounted on the shaft carrying the pulley.
  • the vertical guide on which the belt rests drive is located at the rear of the cabin or laterally.
  • anchor point 2 of the cable is offset from the guide axis and lies between the plane vertical passing through the center of gravity and the bottom of the cabin.
  • an offset of the anchor point beyond the axis of guidance accentuates this force.
  • the adhesion depends on the force F, but covering of the materials constituting the bearing face of the guide and of the driving belts.
  • Such a drive mechanism will advantageously be usable on elevator cars moving in an inclined shaft hopper, force F then being more important.
