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

Embodiment 1

[0048] refer to figure 1 , The present invention discloses an elevator traction wire rope clamping device, which mainly includes a first clamping plate 1 , a second clamping plate 2 , and several connecting components 3 . The first splint 1 and the second splint 2 are arranged opposite to each other, and several connecting assemblies 3 connect the first splint 1 and the second splint 2 in parallel with each other, and are constructed between the first splint 1 and the second splint 2 to form several During the installation interval, the traction wire ropes 9 are clamped by the first clamp plate 1 and the second clamp plate 2 after passing through the installation space in a one-to-one correspondence.

[0049] combine figure 2 Specifically, the first splint 1 and the second splint 2 can be made of angle steel, both of which have a mutually perpendicular fixing part and an engaging part 12, and the fixing parts of the two are provided with several concentric parts at equal int...

Embodiment 2

[0053] refer to Figure 4 , the present invention also discloses a rope cutting method using the elevator traction wire rope device 10 in the first embodiment, and the method includes the following steps:

[0054] Step 1. Measure the distance between the counterweight 30 and the buffer if it exceeds the installation standard range, and calculate the length to be intercepted.

[0055] Specifically, we take an elevator with a 2:1 suspension ratio as an example. For example, for a passenger elevator with a 5-story station, the traction wire rope 9 is about 50m long. If it is suspended at 2:1, the rope length is about 100m. , using spring buffer 20, the buffer distance is 150-400mm. First, arrange a maintenance person in the machine room to drive the car 40 to the top floor at a slow speed. After leveling, turn the elevator to the maintenance state, and notify the waiting maintenance personnel to enter the pit to measure the distance from the counterweight 30 lower beam impact pl...

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...
