Suspender cable broken wire checking device and method for elevator

Abstract

The invention relates to a suspender cable broken wire checking device and method for an elevator. The method adopts the suspender cable broken wire checking method for the elevator to perform the following steps: assembling the suspender cable broken wire checking device for the elevator beside a traction wheel in a machine room by maintenance personnel; holding an elastic sleeve by the user, pulling a non-return gear, separating the two ends, in the peripheral direction, of the elastic sleeve, sleeving the elastic sleeve on a suspender cable, blocking a blocking gear into the non-return gear, and enabling the inner side of the elastic sleeve to cling to the suspender cable; controlling the elevator to travel at low speed by the user, and detouring the suspender cable on the traction wheel; and when the user stops elevator motion, dismounting the suspender cable broken wire checking device for the elevator from the suspender cable, checking the broken wire condition of the suspender cable, and judging whether to replace the suspender cable or not. The method can quickly check a broken wire node of the traction steel wire rope, and can timely judge the broken wire condition; and moreover, the method saves labor and force, and can reduce maintaining and checking cost.

Description

technical field [0001] The invention relates to the technical field of elevator maintenance, in particular to an elevator sling broken wire inspection device and inspection method. 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 is getting faster and faster, the quality requirements for the sling on the elevator are getting higher and higher. During the operation of the elevator, its sling will bypass the car top wheel, traction sheave, Multiple sheaves such as guide wheels and counterweight wheels cause many local damages to the sling during the long-term and multi-frequency operation of the elevat...

Problems solved by technology

But the actual situation is that it takes a lot of time to maintain and check the sling in this way, and it is not so easy to see the broken wires and strands of the sling, and it may be necessary to check the sling once. It takes time and energy to go around the guide wheel many times; in addition, when the sling breaks or strands are slightly broken, there is no need to replace it and it can still be used

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