A vertical elevator with composite locking pins

Abstract

The invention discloses a vertical elevator with a composite locking pin. The vertical elevator comprises a lift car, a well wall, a lift car frame, a locking device, a control lever and stopping blocks. The locking device is arranged on the lift car frame and can make axial movement. One end of the control lever is arranged on the lift car frame and can be adapted to the locking device in shape, and the other end of the control lever is arranged inside the lift car. Moreover, the control lever can make axial movement. The stopping blocks are arranged on the well wall and can be adapted to the locking device in shape. The locking device comprises a first elastic part and the locking pin. One end of the first elastic part is connected with the locking pin, and the other end of the first elastic part is connected with the lift car frame. The locking pin comprises a high manganese steel wire mesh and a metal layer which are coiled with each other, and is formed in the mode of extrusion casting. The high manganese steel wire mesh comprises a set of high manganese steel wires which are interwoven with one another. When an existing fall-preventing device fails, persons in the elevator can brake the elevator manually, so that the fall-preventing purpose is achieved, and the persons in the elevator can be self-rescued.

Description

technical field [0001] The invention relates to a vertical elevator, in particular to a vertical elevator with a compound locking pin. Background technique [0002] In recent years, with the advancement of urbanization and the improvement of residents' living standards, elevators have become an indispensable vertical means of transportation in people's production and life. In order to ensure safe operation, general vertical elevators are equipped with anti-fall devices. It can be realized by devices such as speed gear, safety gear and buffer at the bottom of the hoistway. Once the elevator is found to be falling over speed, the speed limiter will first stop the elevator drive host. If the host still does not stop, the speed limiter will lift the safety gear to clamp the guide rail, forcing the car to stop on the guide rail, and at a certain speed If it hits the buffer directly, the car will also stop. However, errors in any part of the system or failure of components may l...

AI Technical Summary

Problems solved by technology

However, an error in any part of the system or failure of components may lead to the paralysis of the entire anti-fall system. force, but the effect is limited, and it may still cause casualties to the occupants in the elevator

Although the vertical elevator has been equipped with the above two anti-fall protection devices, it still cannot completely avoid the occurrence of elevator falling accidents.
