Elevator connecting rod car door lock device and control method thereof

Abstract

The invention provides an elevator connecting rod car door lock device and a control method thereof. The device comprises a door knife bottom plate, a door knife arm assembly, a lock hook, a connecting rod assembly, a lock hook connecting rod, a starting block, a verification switch and a swing rod assembly; the starting block is used for driving the door knife arm assembly to be folded inwards, so that the connecting rod assembly drives the hook end of the lock hook to rotate upwards through the lock hook connecting rod, the car door lock hook is unlocked, and a switch contact is driven to move on the door knife bottom plate to be separated from a switch socket; and when the swing rod assembly moves on the starting block, the starting block is used for driving the door knife arm assembly to be unfolded outwards through the connecting rod assembly, so that the hook end of the lock hook rotates downwards through potential energy accumulated by an elastic piece, a car door lock is locked, and the switch contact is driven to move on the door knife bottom plate to make contact with the switch socket. Compared with the prior art, a mechanical part and an electrical part can be verified at the same time, the reliability of the car door lock can be improved, the impact of the lock hook on a switch is reduced, and opening and closing of an elevator become simpler and more reliable through a linkage structure.

Description

technical field [0001] The invention relates to an elevator accessory, in particular to an elevator connecting rod car door lock device and a control method thereof. Background technique [0002] Nowadays, elevators, as the most frequently used vertical means of transportation by modern people, not only meet the needs of people's daily life, but also play a very important role in promoting the development of human society, and the safety of elevators has a great impact on our life and production. direct impact. [0003] In the current traditional elevator linkage car door lock device, most of the mechanical parts and electrical parts of the car door lock operate separately. The safety of the elevator car door lock is guaranteed by the mechanical and electrical parts. The mechanical part realizes the corresponding opening of the door system. The electrical part mainly realizes the control of the door lock circuit. The car door lock set according to this conventional method n...

AI Technical Summary

Problems solved by technology

[0005] When the elevator opens and closes the door in various situations, specifically, when the car is in the unlocked area and when the car is not unlocked, the traditional elevator car door lock needs to be realized through different modules, which has a complex structure and high cost. Reduced elevator safety
