Wireless elevator light curtain

Abstract

The invention provides a wireless elevator light curtain. The wireless elevator light curtain comprises a power supply executing mechanism, an action control receiver, a left power supply induction emitter, a right power supply induction emitter, a left light curtain safety touch panel and a right light curtain safety touch panel. The wireless elevator light curtain solves the problem that a light curtain (or a light curtain safety touch panel dual-purpose) of an existing elevator is in a complex transmission mode of wired power supply and wired signal transmission, a light curtain composed of a plurality of connected electrical and mechanical parts is converted into a combination of three non-contact parts, and the effects that the manufacturing process cost is reduced, installation is simplified, maintenance is convenient, the use cost is reduced, stumbling and contact are avoided during operation, and mechanical faults are avoided are achieved.

Description

technical field [0001] The invention is specifically a wireless elevator light curtain. Background technique [0002] In the existing elevator light curtain, the light curtain (safety touch panel) is installed on the side of the moving car door panel. The rod is installed at both ends of the car door, and the middle is connected by a chain to form a moving bracket for the cable. The door panels on both sides of the elevator car are used to open and close the door, and the light curtain accompanying cables move with each other, so the fatigue of mechanical movement will occur, resulting in the occurrence of faults such as cable disconnection; at the same time, when the elevator moves at high speed , the accompanying cable will shake and cause damage due to scratching by obstacles; and because the accompanying cable is routed along the two ends of the door, it is relatively troublesome to maintain. Contents of the invention [0003] The purpose of the present invention is ...
