Integrated car door lock synchronous door knife and integrated car door lock synchronous door knife system

Abstract

The invention discloses an integrated car door lock synchronous door knife and an integrated car door lock synchronous door knife system. The integrated car door lock synchronous door knife comprisesa door knife bottom plate installed on an elevator car door, and a locking hook hinged on the door knife bottom plate and matched with a hook attaching component. The integrated car door lock synchronous door knife further comprises a first blade and a second blade which are movably arranged on the door knife bottom plate and are mutually linked, a swinging piece rotationally mounted on the door knife bottom plate and linked with a motor driving mechanism, a first limiting hole arranged on the door knife bottom plate so as to limit the swinging amplitude of the swinging piece, a first elasticpiece acting between the door knife bottom plate and the swinging piece to drive the swinging piece to reset, a transmission piece linked with the swinging piece to drive the locking hook to rotate, asecond elastic piece acting between the door knife bottom plate and the locking hook to drive the locking hook to reset, and a linkage arm linked with the swinging piece to drive the first blade andthe second blade to open and close. The integrated car door lock synchronous door knife provided by the invention is suitable for different types of door machines, and the installation and debugging process is simpler.

Description

technical field [0001] The application relates to the technical field of elevators, in particular to an integrated car door lock synchronous door knife and a door knife system. Background technique [0002] With the gradual improvement of elevator safety performance requirements, the new GB7588 standard requires that the motor door opening mechanism needs such a function: it can lock the car door in the non-leveling section of the elevator, and allow the car door to be locked in the leveling section of the elevator under any circumstances. Can be unlocked to allow passengers to escape. [0003] In order to achieve the above functions, the following two solutions are usually adopted: [0004] The first type is an independent car door lock, which is not directly related to the door knife and landing door kick that execute the door opening; [0005] The second type is the car door lock integrated in the door knife, relying on the clamping of the landing gate kick to judge whe...

AI Technical Summary

Problems solved by technology

[0007] The existing integrated car door lock synchronous door knife can be roughly divided into two categories, single-blade unlocking (the first blade, the unlocking blade) and double-blade unlocking (the first blade and the second blade can both achieve the unlocking effect), and the single-blade unlocking The method has high requirements for installation. If the installation is not good, there may be asynchrony between the car door and the landing door at the moment of opening, and the synchronization of the hall car door is not ideal. In addition, when installing the landing door, it is necessary to strictly require the center of the landing door ball and the unlocking blade. The vertical distance, otherwise it is easy to cause the car door to fail to open and the elevator to report failure

[0008] With the existing double-blade unlocking synchronous door knife, the position of the force axis of the door machine needs to be adjusted according to different types of door machines, and the corresponding door machine control parameters also need to be adjusted, resulting in poor adaptability of the double-blade unlocking synchronous door knife
