Elevator traction rope clamping device and rope cutting method applying same

Abstract

The invention relates to an elevator traction rope clamping device and a rope cutting method applying the rope clamping device, and relates to the technical field of elevator detection and maintenance. According to the technical scheme, the rope clamping device comprises a first clamping plate, a second clamping plate and a plurality of connecting assemblies, wherein the first clamping plate and the second clamping plate are arranged oppositely, the connecting assemblies are used for connecting the first clamping plate and the second clamping plate, a plurality of mounting intervals corresponding to the traction steel wire ropes in one-to-one correspondence and used for allowing the traction steel wire ropes to pass through are formed between the first clamping plate and the second clamping plate through the connecting assemblies, and the plurality of traction steel wire ropes are clamped between the first clamping plate and the second clamping plate through the connecting assemblies.According to the rope clamping device and the rope cutting method applying the rope clamping device, the plurality of traction steel wire ropes are fixed, so that the traction steel wire ropes can beprevented from being crossed and scattered during rope cutting and mounting, and the maintenance work efficiency of rope cutting is improved.

Description

technical field [0001] The invention relates to the technical field of elevator inspection and maintenance, in particular to an elevator traction rope clamping device and a rope cutting method using the device. Background technique [0002] The traction wire rope of the elevator, after installation and use, will produce structural elongation with the increase of running time. Theoretically, the elongation of the traction wire rope is about 0.5%. For middle and high-rise elevators, especially For a 2:1 suspension elevator, the impact cannot be ignored. For example, for a passenger elevator with 5 floors, the traction wire rope is about 50m long. If the 2:1 suspension is used, the rope length is about 100m, and the elongation is 0.5%. There are more than 500mm. We know that the buffer distance of the hydraulic buffer is 150-400mm, and the buffer distance of the spring buffer is 200-300mm. After the traction wire rope is stretched and deformed, it will affect the safe operatio...

AI Technical Summary

Problems solved by technology

[0005] 1. Maintenance workers need to remove all the traction wire ropes for maintenance. According to the normal elevator, the number of traction wire ropes is 6, and the weight is relatively large. It takes a lot of manpower to disassemble and install, and the work efficiency is low. And there is a big security risk;

[0006] 2. Since there are 6 traction wire ropes, it is easy to cross and scatter during disassembly, interception, and installation, which affects maintenance efficiency
