Maintenance inspection device and maintenance inspection method for elevator traction steel wire ropes

Abstract

The invention relates to a maintenance inspection device and maintenance inspection method for elevator traction steel wire ropes. The method adopts the maintenance inspection device for execution andcomprises the following steps that a maintenance person assembles the maintenance inspection device for the elevator traction steel wire ropes, the maintenance person holds a handle, and presses an extrusion part of a first clamp body and an extrusion part of a second clamp body, so that the traction steel wire ropes are surrounded in rope surrounding holes formed by every two inner clamping parts, and cotton yarn is guaranteed to encircle the outer surfaces of the traction steel wire ropes; an elevator is controlled to run at a low speed, so that the traction steel wire ropes are enabled tobypass the whole process; when the cotton yarn is hitched, the elevator is immediately stopped, the maintenance inspection device is disassembled, the yarn breaking situation of the traction steel wire ropes is observed and inspected carefully, and whether the traction steel wire ropes need to be replaced or not is judged. According to the method, wire breaking and strand breaking nodes of the traction steel wire ropes can be quickly checked, so that wire breaking and strand breaking condition can be timely judged, the method is time-saving and labor-saving, and the maintenance and inspectioncost can be reduced.

Description

technical field [0001] The invention relates to the technical field of elevator maintenance, in particular to a maintenance inspection device and a maintenance inspection method for elevator traction wire ropes. Background technique [0002] Nowadays, when elevators are becoming more and more popular means of transportation, their safety issues are also receiving more and more attention because they are related to the vital interests of each of us. There are endless news about elevator accidents all over the country. The safety maintenance and inspection work of elevators is top priority. [0003] As the lifting speed of the elevator becomes faster and faster, the quality requirements for the steel wire ropes on the elevator are also getting higher and higher. During the operation of the elevator, its traction wire rope will bypass the car top wheel, traction sheave, Multiple sheaves such as guide wheels and counterweight wheels cause many local damages to the traction wire...

AI Technical Summary

Problems solved by technology

However, the actual situation is that it takes a lot of time to maintain and inspect the traction wire rope, and it is not so easy to detect the broken wires and strands of the traction wire rope with the naked eye. To check the traction wire rope may require the traction The traction wire rope goes around the traction sheave many times, which is time-consuming and labor-intensive; in addition, when the traction wire rope breaks or strands are slightly broken, it does not need to be replaced and can still be used

However, the traction wire rope of the elevator needs to be inspected regularly, and when the traction wire rope is inspected again, the above inspection process needs to be repeated, which is labor-intensive and expensive for maintenance and inspection
