Device and method for monitoring running positions of steel wire ropes for elevator

Abstract

The invention discloses a device for monitoring running positions of steel wire ropes for an elevator. The device comprises a photoelectric sensor and a controller, wherein the photoelectric sensor comprises an emitting end and a receiving end, which are respectively arranged on two sides of the steel wire ropes of the elevator, and are arranged in one-to-one correspondence relative to the steel wire ropes of the elevator and gaps on two sides of each steel wire rope of the elevator; the controller controls light rays emitted by the emitting end to irradiate the steel wire ropes of the elevator and the gaps on two sides of each steel wire rope in a direction perpendicular to the running direction of the steel wire ropes of the elevator, and controls the receiving end to receive the light rays; and the controller judges the running positions of the steel wire ropes of the elevator according to light ray information received by the receiving end. The invention also provides a method for monitoring the running positions of the steel wire ropes of the elevator, and by the method, the running positions of the steel wire ropes of the elevator can be monitored in real time, and the operation safety of the elevator is improved.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to an elevator wire rope running position monitoring device and a monitoring method. Background technique [0002] In the current technology, whether the operating condition of the elevator wire rope is normal is judged by the periodic manual inspection of the elevator maintenance personnel. In this way, when the elevator wire rope has "broken rope", "wrapped", "jumped to other rope grooves", etc. in the middle period of two manual inspections, and deviates from its normal operating position, it cannot be found and dealt with in time. , the elevator will run with a fault until it is detected during the next manual inspection, or until the elevator fails and the elevator stops and people are trapped. Under the situation that this elevator wire rope failure cannot be found and dealt with in time, there will be potential safety hazards in the elevator's continued operation. Contents ...

AI Technical Summary

Problems solved by technology

In this way, when the elevator wire rope has "broken rope", "wrapped", "jumped to other rope grooves", etc. in the middle period of two manual inspections, and deviates from its normal operating position, it cannot be found and dealt with in time. , the elevator will run with a fault until it is detected in the next manual inspection, or until the elevator fails and the elevator stops and people are trapped

In the case that the elevator wire rope failure is not found and dealt with in time, there will be safety hazards in the elevator's continued operation.
