Anti-scrabbling door vane structure for elevator

Abstract

The invention relates to an anti-scrabbling door vane structure for an elevator; a climbing motion of a rotating ball of a vane lifting plate on a guide rail urges the rotation of the vane lifting plate so as to drive an unlocking plate to move; the unlocking plate drives a connecting rod mechanism through a transmission arm to perform a relative staggered motion; when the connecting rod mechanism clamps a door locking ball, the unlocking plate rotates to drive an interlocking plate to rotate to realize an unlocking function; and the motion stability of a left door vane and a right door vane is guaranteed through a limiting stop shaft and a limiting baffle plate. The structure realizes the use effect of an asynchronous door vane and a synchronous door vane, improves the debugging and mounting efficiency, and realizes the electrified satisfaction of door scrabbling force requirements and the car scrabbling distance requirements in a non-flat floor state.

Description

technical field [0001] The invention relates to the production and manufacturing technology industry of elevators, in particular to an anti-snipping door knife structure for elevators. Background technique [0002] In cities, the use of elevators is convenient for people to go up and down the stairs, bringing greater convenience to life, and its safety performance is getting more and more attention. Therefore, when producing and manufacturing elevators, it is necessary to eliminate all Safety accidents may occur, and the door knife structure of the elevator ensures the safety of the elevator in operation. It is mainly a mechanical device for unlocking and closing the lock, which is realized by the movement of the door panel. When the elevator is in use, it is operated with electricity. In the use of the integrated car, the synchronous door knife is usually used. When the synchronous door knife is used, the structure of the door machine becomes very complicated, which increas...

AI Technical Summary

Problems solved by technology

When the elevator is in use, it is operated with electricity. In the use of the integrated car, the synchronous door knife is usually used. When the synchronous door knife is used, the structure of the door machine becomes very complicated, which increases the failure rate of the door machine and the installation and commissioning cycle. The national standard GB7588 has added a new requirement: "For any reason, when the elevator stops in the unlocking area, it should be able to unlock the landing door with a triangular key or through the car door at the landing where the car is located. With a force exceeding 300N, manually open the car door and landing door". At the same time, the distance to open the non-flat car door cannot exceed 50mm under the force of 1000N. At present, all door knife structures with integrated car door locks cannot In the case of being charged at the same time, it meets the requirements of the door opening force and the opening distance of the car door in the non-leveling state
