Description

Bidirectional falling-preventing device for elevator

Technical Field

The utility model relates to the technical field of elevator anti-falling devices, in particular to a bidirectional elevator anti-falling device.

Background

With the rapid development of society, high-rise buildings in cities are more and more, and elevators are necessary devices for the high-rise buildings, so that people can travel conveniently, and the life of people is more convenient. However, the serious problem is that the news layer of the elevator fault in recent years is endless, so that the people feel 24820 and 24820 in riding the elevator are bad. In practice, the elevators are all provided with anti-falling devices, and the existing anti-falling devices of the elevators are mainly realized by devices such as a speed limiter, safety tongs and a buffer at the bottom of a hoistway. Once the elevator is found to descend at overspeed, the speed limiter firstly stops the elevator driving host, if the host is still not stopped, the speed limiter can lift the safety tongs to clamp the locking device guide rail, the elevator car is forced to be stopped on the locking device guide rail, and in addition, the elevator car can be stopped if the elevator car directly impacts on the buffer at a certain speed.
