Definitions

  • the invention relates to a cable elevator.
  • a cable elevator comprises an elevator car suspended on one of the two strands of a cable which, passed on a pulley overhanging the technical sheath in which the cabin is circulating, has its other strand which supports a counterweight.
  • the pulley is then locked in rotation on a shaft rotated 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 groove of the pulley and the cable is sufficient to prevent slipping of the cable into the groove of the pulley.
  • the counterweight develops a force opposite to that produced by the cab and therefore limits the load to be driven.
  • the load to be moved is then equal to the differential between the weight of the cabin with the passengers and the weight of the counterweight.
  • the motor torque that drives this pulley via the shaft depends on the load to be moved and, more specifically, the load differential but also the diameter of the pulley.
  • the motor torque must be relatively important.
  • a brake is positioned in particular for safety.
  • This space is usually called technical room or machinery.
  • the toothed wheels together with the racks, move and guide the cab.
  • the brake is then mounted on the motor drive shaft carried by the top of the cab.
  • Such a device is very noisy.
  • a training device is also known DE-A-3523187 consisting of pinching a wing of a profile using two wheels, one of which is driving.
  • the wheels are mounted so that they form the jaws of a clamp.
  • the invention proposes a solution for overcoming the aforementioned drawbacks.
  • the pulley is carried by a shaft located above the hopper.
  • the cab is usually guided in translation in the hopper. The same is true of the counterweight.
  • the cab is carried by a bracket-shaped support 100 commonly called arcade 100.
  • This arcade 100 laterally has two slides 101 cooperating with vertical guides 9.
  • the figure 2 shows a cross section showing the arcade, the slides 101 and the vertical guides 9 T-shaped.
  • the bottom of the cabin is thus close to the guide surface thus plating the leading strand of the means 6 of displacement of the cabin.
  • the width or cumulative width of the leading strands of the drive belts and the length of the driving strands determine the area in contact with the guide.
  • This surface in contact with the force applying the said leading strands on the guide partly determines the adhesion for driving the cabin.
  • the anchoring point of the cable of the cabin is offset relative to the vertical axis passing through the center G of gravity of the cabin so that is then exercised a vertical force P but also a force F oriented towards the vertical guide.
  • Such a cab drive device can reduce the size of the engine because the drive torque of the drive belt can be lower.
  • the moving means 6 is located under the cab.
  • the moving means is located 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 drive belt is based is at the rear of the cab or laterally.
  • the anchoring point 2 of the cable is offset relative to the guide axis and is between the vertical plane passing through the center of gravity and the bottom of the cabin.
  • an offset of the anchoring point beyond the guide axis accentuates this force.
  • the adhesion depends on the force F, but not on the materials constituting the bearing surface of the guide and the driving belt or belts.
  • Such a drive mechanism will be advantageously usable on elevator cabs that move in a hopper with an inclined axis, the force F then being greater.

Seilaufzug nach Anspruch 1, dadurch gekennzeichnet, daß der Verankerungspunkt (10) des Seils der Kabine gegenüber der durch den Schwerpunkt (G) der Kabine verlaufenden vertikalen Achse versetzt ist, so daß nun eine vertikale Kraft (P) aber auch eine in Richtung der vertikalen Führung gerichtete Kraft (F) ausgeübt wird.
  5. Seilaufzug nach Anspruch 1, dadurch gekennzeichnet, daß das Bewegungsmittel (6) unter der Kabine angeordnet ist.
  6. Seilaufzug nach Anspruch 1, dadurch gekennzeichnet, daß das Bewegungsmittel sich oberhalb des Daches der Kabine befindet.
  7. Seilaufzug nach Anspruch 1, dadurch gekennzeichnet, daß die vertikale Führung, an der sich der Antriebsriemen abstützt, an der Rückseite der Kabine oder an der Seite befindet.
  8. Seilaufzug nach Anspruch 1, dadurch gekennzeichnet, daß die Seite des Riemens, welche mit der Führung in Kontakt ist, gekerbt ist.
