Elevator traction rope cutting device and method

Abstract

The invention belongs to the technical field of elevator installation and maintenance, and provides an elevator traction rope cutting device and method. The elevator traction rope cutting device mainly comprises an upper clamping plate assembly, a lower clamping plate assembly and an adjusting assembly. The upper clamping plate assembly comprises an upper clamping plate, a first auxiliary clamping plate and a first fixing assembly, and a first clamping space for installing a traction rope is formed between the upper clamping plate and the first auxiliary clamping plate; the lower clamping plate assembly comprises a lower clamping plate, a second auxiliary clamping plate and a second fixing assembly, and a second clamping space for installing the traction rope is formed between the lower clamping plate and the second auxiliary clamping plate; and the adjusting assembly comprises an adjusting rod and an adjusting piece connected with the adjusting rod, the adjusting rod penetrates through the lower clamping plate and the upper clamping plate and then is connected with the adjusting piece, and the connecting position of the adjusting piece on the adjusting rod is adjustable. According to the elevator traction rope cutting device and method, the cutting operation of the traction rope can be simpler, more convenient and more reliable, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of elevator installation and maintenance, and in particular relates to an elevator traction rope cutting device and a method thereof. Background technique [0002] After the elevator has been running for a period of time, the traction rope will be partially elongated due to stretching. When the traction rope is elongated, the force on the traction rope will also Unevenness occurs, which affects the normal operation of the elevator; therefore, when the traction rope is stretched to a certain extent, it needs to be cut. [0003] At present, the elevator industry usually adopts the method of cutting the traction rope: use wooden squares or steel beams to support the bottom of the counterweight in the pit, and use a chain hoist to lift the car on the top of the machine room or shaft, so as to realize The overall slack of the traction rope is then cut. However, this method uses a large number of tools, large vo...

Problems solved by technology

However, this method uses a large number of tools, large volume, heavy weight, inconvenient to carry, and the movement of the construction work is large, which has a significant impact on the residents; and after the traction rope is loosened as a whole, it is easy to cause the traction rope to break away from the corresponding rope groove After cutting, it is necessary to carefully check and confirm that each traction rope returns to the corresponding rope groove of each sheave, otherwise the misplaced operation will cause elevator damage or accidents; for the case where only a single or part of the traction rope needs to be cut, this overall There are also deficiencies in flexibility and pertinence in the way of loosening all the traction ropes
