Abstract

The invention provides a protecting device for preventing an elevator cage from accidently moving. The protecting device for preventing the elevator cage from accidently moving comprises a cage monitoring system, a first safety relay and a second safety relay, wherein the cage monitoring system is connected with the first safety relay and the second safety relay; the cage monitoring system is used for monitoring the position information and the speed information of the elevator cage and respectively outputting the position information and the speed information to the first safety relay and the second safety relay; the first safety relay and the second safety relay are used for performing safety control on the elevator cage according to the position information and the speed information of the elevator cage. The protecting device for preventing the elevator cage from accidently moving provided by the invention can reduce the potential safety hazard caused by the accident moving of the elevator cage and can increase the whole safety performance of the elevator.

Description

technical field [0001] The present invention relates to elevator technology and, in particular, to a protection device against unintentional movement of an elevator car. Background technique [0002] Elevator is a kind of vertical lifting means of transportation, which can carry passengers or goods by pulling the car through the power unit. With the development of computer technology, automation technology and power electronics technology, the demand and popularity of elevators in high-rise buildings and public places are getting higher and higher. [0003] When the elevator car reaches the door area of ​​the floor designated by the passenger, the elevator drive system will control the elevator car to stop the vertical movement, and open the car door of the elevator car and the hall door of the floor, so that passengers can enter and exit the elevator car. However, during the operation of the elevator, there may be unintended car motion (Unintended Car Motion, UCM) in the e...
