An elevator self-control buffer device

Abstract

The invention provides an elevator self-control buffer device installed between the bottom of a lift car of an elevator and the bottom of an elevator outer case. The innovation points of the elevator self-control buffer device lie in that the buffer device comprises a jacking pressing device and a support device; the support device is fixedly installed below the jacking pressing device and is connected with the inner wall of the side face of the outer case, and a buffer support effect is achieved; when being subjected to weightlessness pressure, the jacking pressing device makes contact with the bottom of the lift car; the jacking pressing device comprises a jacking pressing column and a winding spring; the winding spring is spirally wound on the jacking pressing column, and a gap is reserved between the winding spring and the jacking pressing column in the width direction; and the height of the winding spring is smaller than that of the jacking pressing column. The elevator self-control buffer device can sense whether the elevator falls, then the elevator self-control buffer device is started through self control, the precision is high, the intelligent level is high, the survival rate of passengers during falling of the lift car is further increased, and the personal safety during accidental falling of the elevator is enhanced greatly.

Description

technical field

[0001] The invention relates to the technical field of elevator safety, in particular to an elevator self-control buffer device. Background technique

[0002] At present, elevator safety accidents occur frequently all over the country, and one of the common accidents is that the elevator accidentally falls and causes people to fall or die. Moreover, according to the development history of elevators in our country, elevators in our country are gradually entering a critical period of general aging, and the problem of elevator safety is becoming increasingly prominent. However, the elevators that are currently in service or about to be put into use all over the country generally lack safety protection devices. For the safety problem of elevators, manufacturers mostly carry out technological improvement from the angle of controlling elevators to prevent them from falling, and lack of elevators for passengers to save themselves when falling. In the prior art, so...
