Elevator anti-falling device

Abstract

The invention discloses an elevator anti-falling device. The elevator anti-falling device comprises four guide rails fixedly arranged at four corners of an elevator shaft in a rectangular array distribution manner, wherein a lift car is arranged in the center of the array of the four guide rails in an up-down moving manner; a cavity with a forward opening is formed in the lift car; fixed doors aresymmetrically and fixedly connected to the left wall and the right wall of the front side of the cavity separately; and movable doors are arranged at the front sides of the fixed doors in a left-right sliding manner. According to the elevator anti-falling device, suspension shafts and suspension short shafts can be automatically driven to slide into suspension holes, formed in each floor, of theguide rails while the movable doors are opened, and the suspension shafts and the suspension short shafts slide out of the suspension holes when the movable doors are about to be completely closed; and when it is detected that an elevator falls, the lift car is rapidly stopped through a jamming device, the interior of the lift car is stable, after the lift car is stably stopped, the lift car is lifted to the landing door position through a lifting device, the movable doors are opened, the suspension shafts and the suspension short shafts slide into the suspension holes, a reset device is started after a danger is eliminated, the jamming device is reset, and the elevator returns to normal.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator fall prevention device. Background technique [0002] In daily life, elevator falling incidents happen from time to time. When people enter and exit the elevator and when the elevator is moving up and down, the elevator will also have a very dangerous drop. In the process of falling and being stuck, it will also cause great harm to people in the elevator. With a large impact force, after the elevator falls and gets stuck, it often happens that the car door and the floor are not at the same height, which is not conducive to people's escape. In addition, if the elevator suddenly falls during the escape process, it will get stuck and cause life-threatening , a kind of elevator anti-fall device described in the present invention can solve the above-mentioned problems. Contents of the invention [0003] In order to solve the above problems, this example designs an elevator fall...

[0002] In daily life, elevator falling incidents happen from time to time. When people enter and exit the elevator and when the elevator is moving up and down, the elevator will also have a very dangerous drop. In the process of falling and being stuck, it will also cause great harm to people in the elevator. With a large impact force, after the elevator falls and gets stuck, it often happens that the car door is not at the same height as the floor, which is not conducive to people's escape. In addition, if the elevator suddenly falls during the escape process, it will jam people's bodies, which will be life-threatening , a kind of elevator anti-fall device that the present invention sets forth can solve the above-mentioned problems
