Synchronous elevator door vane device with locking mechanism

Abstract

The invention discloses a synchronous elevator door vane device with a locking mechanism. The synchronous elevator door vane device comprises a door vane bottom plate, the locking mechanism and a traction device. The locking mechanism comprises a lock hook, a verification switch support and a drive device. The lock hook is movably connected with the door vane bottom plate through a first center shaft. The lock hook is used for being in interlocking cooperation with the verification switch support. The traction device comprises a movable plate. The movable plate is movably connected with the door vane bottom plate through a second center shaft. The situation that when an elevator fails or is powered off and stops in the non-landing region, an elevator car door is opened by accident is avoided by the adoption of the structure. The synchronous elevator door vane device with the locking mechanism is simple in structure, high in safety and convenient to mount and maintain.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator synchronous door knife device with a locking mechanism. Background technique [0002] As a vertical transportation tool, the elevator is very convenient. In daily life, it is basically used every day. Accidents caused by the equipment itself or improper human operation methods also occur from time to time. In particular, door system problems account for about 80% of elevator accidents. For example, in a shearing accident, when the elevator door is opened or not completely closed, if someone is between the car door and the landing door, it can cause personal injury; in a falling accident, when the elevator car door and the landing door are opened, the elevator car But it is not at the landing, which may easily cause the occupants to fall into the well at this time; there are also some injuries caused by sudden failure or power failure, the occupants are trapped in t...

AI Technical Summary

Problems solved by technology

For example, in a shearing accident, when the elevator door is opened or not completely closed, if someone is between the car door and the landing door, it can cause personal injury; in a falling accident, when the elevator car door and the landing door are opened, the elevator car However, it is not at the landing, and it is easy to cause the occupants to fall into the well at this time; there are also some accidents caused by sudden failure or power failure, occupants trapped in the car, and rashly opening the door.

[0003] The current elevator door operator system has been developed into a permanent magnet synchronous door operator system through mechanical door operator and frequency conversion door operator. Its main purpose is to make the door operator system more and more safe and intelligent, and these door operator systems There is also a potential safety hazard that the car door in the car can be accidentally opened
