Definitions

  • each of elevators is provided with a speed governor for regulating the rapid descent of the elevator when a rope connected to the elevator is broken or the elevator is in any abnormal state.
  • a speed governor is installed in a machinery chamber.
  • a rope of the speed governor connected to the elevator (hereinafter, referred to as a "rope") is wound on a main wheel of the speed governor, thus rotating the main wheel.
  • a pendulum of the main wheel of the speed governor moves outwardly by the centrifugal force, and operates an overspeed switch so that power connected to an electric motor of a hoist gear is cut off and simultaneously a brake of the hoist gear is operated so as to stop the elevator.
  • Fig. 3 is a detailed perspective view illustrating the connection of a driving shaft and wedges in the device for stopping an elevator in emergency in accordance of one embodiment of the present invention
  • the defects of the elevator 500 are examined and repaired. Then, when the ratchet 31 is rotated to move downwardly, the emergency descent stop unit 200 is returned to its initial state. Accordingly, it is possible to normally operate the elevator 500 immediately after the repair of the elevator 500.
  • the ratchet is rotated to move downwardly. Then, the device is immediately returned to its initial state. Accordingly, it is possible to easily and quickly operate the elevator in a normal state immediately after the repair of the elevator.

Abstract

L'invention concerne un dispositif permettant l'arrêt d'urgence d'un ascenseur. Ce dispositif comprend une unité d'arrêt d'urgence en descente permettant d'arrêter rapidement et efficacement la descente en survitesse de l'ascenseur sans régulateur de vitesse additionnel pourvu d'un câble afin d'empêcher la descente de l'ascenseur lorsqu'il dysfonctionne. En variante, le dispositif d'arrêt d'urgence de l'ascenseur comprend à la fois une unité d'arrêt d'urgence en descente et une unité d'arrêt d'urgence en montée de telle manière que la montée en survitesse de l'ascenseur tout comme la descente en survitesse de l'ascenseur soient arrêtées, ce qui améliore la sûreté de l'ascenseur et la protection des passagers et marchandises transportés dans l'ascenseur contre tout danger.
