Lift with detection device for detecting displacement of door ball of lift hall door

Abstract

The invention relates to the technical field of a lift, in particular to a lift with a detection device for detecting displacement of a door ball of a lift hall door. The lift comprises a lift main body; the lift main body comprises a lift hall car door linkage device; the lift hall car door linkage device comprises a lift door opening machine arranged on a lift car as well as a landing door device arranged on the lift hall door; the lift door opening machine comprises a door knife; the landing door device comprises a door ball linked with the door knife and further comprises a photographing detection system; the photographing detection system comprises a photographing device and an image processing system; the photographing device is connected with the image processing system; the photographing detection system further comprises a shell; the photographing device and the image processing system are arranged in the shell; a light-transmitting opening is formed in the shell; the photographing direction of the photographing device faces towards the light-transmitting opening; the photographing direction of the photographing device faces towards the door ball through the light-transmitting opening; the shell is fixed on the door knife. The traditional photographing detection system for detecting displacement is arranged on the door knife, so that displacement monitoring of the doorball is realized.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to elevators. Background technique [0002] The importance of the elevator as a vehicle for transporting passengers up and down the building is self-evident. However, as a special electromechanical equipment, the elevator has national design and manufacturing standards and inspection standards, and as an ordinary transportation tool, the structure of its moving parts During long-term use, the displacement must occur and needs to be adjusted during equipment maintenance. However, the displacement of the moving parts often occurs before the maintenance work, resulting in elevator failure due to the displacement of the moving parts. [0003] Among them, the elevator failure includes the displacement of the gate ball on the hall door to cause the elevator failure. [0004] In the elevator hall car door linkage device, the door knife on the elevator door opener will drive the gate b...

AI Technical Summary

Problems solved by technology

[0004] In the elevator hall car door linkage device, the door knife on the elevator door opener will drive the gate ball on the hall door to make relative motion, and the relative motion of the gate ball will drive the hall door device connector and the hall door to open, but in order to prevent the elevator from running up and down When the door knife touches the gate ball, the width of the gate ball is generally smaller than the inner width of the door knife. However, when the hall door runs for a long time or is affected by abnormal external forces, the gate ball will be displaced. When the elevator is running up and down, the door knife on the car door will It will touch the croquet, which will cause the safety chain of the hall door lock to act, and the elevator will fail.
