Elevator car door motor structure

Abstract

The invention relates to an elevator car door motor structure which comprises a door head, wherein a left door plate and a right door plate are arranged below the door head; a door plate guide track used for sliding of the left door plate and the right door plate is arranged below a door motor; a left hanging plate is arranged on the left door plate; a right hanging plate is arranged on the right door plate; a door coupler is arranged on the left hanging plate; a driving wheel and a driven wheel are arranged in the door head; a synchronous belt is arranged on the driving wheel and the driven wheel; the driving wheel is driven by a drive motor; the left hanging plate is connected onto the upper layer of the synchronous belt through a left connecting plate; the right hanging plate is connected onto the lower layer of the synchronous belt through a right connecting plate; a hanging plate guide track is arranged in the door head; the left hanging plate and the right hanging plate are arranged in the hanging plate guide track; guide balls are arranged on both the left hanging plate and the right hanging plate; and clamping plates are arranged on the inner sides of the left hanging plate and the right hanging plate, and clamped on the hanging plate guide track. As the clamping plates are arranged on the hanging plates and clamped on the hanging plate guide track, shaking of the hanging plates during motion and generation of noise can be reduced, smooth running can be guaranteed, and derailment can be avoided; and the elevator car door motor structure is convenient to use.

Description

technical field [0001] The invention relates to the production and manufacturing industry of elevators, in particular to an elevator car door machine structure. Background technique [0002] The elevator door operator is a mechanism responsible for opening and closing the elevator hall car door. When it receives the elevator door opening and closing signal, the elevator door operator controls the door opening motor through its own control system, and converts the torque generated by the motor into a specific direction. force to close or open the door. When the door closing force is greater than 150N, the door operator will automatically stop closing the door, and open the door in reverse, playing a certain degree of door closing protection. [0003] The existing elevator door machine structure includes a door head, a drive assembly fixed on the door head, a motor, and a hanging plate assembly. The hanging plate assembly is connected with the driving assembly and the motor, ...
