Elevator door lock assembly and positioning method for assembly

Abstract

The invention discloses an elevator door lock assembly, which comprises a door lock body, a lock plate, a locking mechanism, a control mechanism, wherein the locking mechanism comprises an electromagnet, a locking pin and a spring; the locking pin and the lock plate are rotatably connected; the electromagnet is electrically connected with the control mechanism; before a car arrives, the lock plate is clamped and fixed on a catch plate, and an elevator landing door is in a locked state; after the car arrives, a car arrival signal is transmitted to a control system by a leveling inductor of an elevator; a landing call signal and a leveling inductor signal are combined by the control system to accurately output an unlocking signal to the electromagnet of the floor; after the electromagnet is electrified, the locking pin is sucked up; the lock plate is driven by the locking pin to do anticlockwise rotation; a bayonet is separated from the catch plate, and the landing door is opened; when the car leaves, a signal is output to the electromagnet by the control mechanism; the electromagnet is interrupted, the locking pin resets under the effect of gravity of the spring or the locking pin; the lock plate rotates to reset; the bayonet is clamped on the catch plate to realize the linkage of the landing door and the car so as to realize accurate opening and closing on the landing door.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator door lock assembly and a positioning method for the assembly. [0002] Background technique [0003] The elevator door lock is a component installed on the landing door or car door to play a locking role. It is used to open the landing door when the car arrives at the floor, and lock and fix it before the car arrives or after leaving, so as to lock it. effect. [0004] Garbage elevators are generally used to transport goods and sundries, but since the sundries elevator usually does not have automatic car doors, it is very necessary to realize the linkage between the door lock and the car. [0005] Traditional door locks for sundry elevators generally use door balls to link with door knives installed on the car. However, since sundries elevators are usually not equipped with automatic doors, it is impossible to realize the linkage between the car door a...
