Embodiment Construction

[0016] Such as Figure 1-3 As shown, the explosion-proof elevator landing door lock assembly includes a PLC control system, a motor, a door machine body 1, and a guide rail horizontally arranged on the door machine body 1. A door knife on the hanging board 2, the landing door is fixedly installed on the hanging board 2, and also includes a base plate 3 fixed on the door machine body 1, the front side of the base plate 3 is fixed with a vertically arranged first A limit switch 4 and a second limit switch 5 arranged horizontally, the door knife has a door hook 6 linked with it, the bottom plate 3 is horizontally fixed with an auxiliary hook 7 that is fastened with the door hook 6, the The top surface of the door hook 6 is fixed with a first trigger striker 8 that is buckled with the first limit switch 4. The first trigger striker 8 rotates with the door hook 6 and triggers the first limit switch 4 to be controlled by the PLC. The system transmits electrical signals to verify wh...

Abstract

The invention discloses an explosion-proof elevator landing door lock catch assembly. The assembly comprises a PLC control system, a motor, a door machine body and a guide rail transversely and horizontally arranged on the door machine body, and a hanging plate is arranged on the guide rail in a relatively sliding manner. The assembly has the beneficial effects that a second triggering striking rod is matched with a second limiting switch in an inserted and buckled manner and triggers the second limiting switch to transmit an electric signal to a PLC control system, meanwhile, through bucklingof a door hook and an auxiliary hook, a first triggering striking plate rotates along with the door hook and triggers a first limiting switch to transmit an electric signal to the PLC control system,if the two electric signals are landing door closing signals, the PLC control system locks a motor to enable the motor not to rotate, and is matched with a mechanical door hook lock catch structure,so that external personnel cannot push open a landing door, sparks or heat effects cannot be generated in the triggering process of the first limiting switch and the second limiting switch, and the standard of national explosion-proof elevators is met.

Description

Technical field: [0001] The invention relates to the technical field of elevators, in particular to an explosion-proof elevator landing door lock assembly. Background technique: [0002] The existing elevator landing door lock structure adopts the traditional exposed copper sheet contact to generate electrical signals, sparks or thermal effects are generated during the copper sheet contact process, which does not meet the explosion-proof requirements of explosive environments in special industries, and the existing layer The door lacks a protective structure, which makes the car easy to be opened by outside personnel during the lifting process, resulting in personal injury, so the elevator cannot meet the national explosion-proof elevator standard. Invention content: [0003] The object of the present invention is to provide an explosion-proof elevator landing door latch assembly in order to solve the existing problems. [0004] Technical solutions of the present inventio...
