Elevator door motor system based on safety loop detection

Abstract

The invention discloses an elevator door motor system based on safety loop detection. The elevator door motor system comprises an elevator shaft, a lift car system is embedded in the elevator shaft, alift car door system is installed on one side of the lift car system, an infrared correlation switch is fixedly installed at the top of the front surface of the lift car system, and the infrared correlation switch is aligned with an infrared correlation switch installed at the top of a landing door in position; and an electric control system, an electric dragging system and a dragging system arefixedly installed at the top end of the elevator shaft, and the electric dragging system is electrically connected with the dragging system. According to the elevator door motor system based on safetyloop detection, when the infrared correlation switch installed at the top end of the lift car system is aligned with the infrared correlation switch installed on the inner side of the landing door inposition, a servo motor designed by the lift car door system drives a gear to rotate, the gear rotates to drive a rack to move, opening and closing of a lift car door are controlled through movementof the rack, original distance lifting control is replaced, the lift car door and the landing door are located at the same horizontal height, and it is avoided that fall is formed between the lift cardoor and the landing door to affect use of the elevator.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator door machine system based on safety loop detection. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° from the plumb line. It runs continuously on the crawler belt, commonly known as escalator or moving walk. The fixed lifting equipment serving the specified floors. The vertical elevator has a car that runs between at least two vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. [0003] During the operation of the existing elevator, it is easy to have a height gap between the car door and the landing door, which is no...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an elevator door machine system based on safety loop detection to solve the problem that the existing elevator in the above background technology is prone to high insertion between the car door and the landing door during the running process, which not only does not It is convenient for people to get on and off the car, and it affects the normal operation of the elevator
