Steel wire rope used for high-rise high-speed elevator

Abstract

The invention relates to a steel wire rope used for a high-rise high-speed elevator. The steel wire rope used for the high-rise high-speed elevator is characterized by comprising a sisal hemp core, inner layer strands and outer layer strands. Eight inner layer strands wrap the sisal hemp core in a twisted mode, eight outer layer strands wrap the inner layer strands in a twisted mode, and the sisal hemp core is formed by sisal hemp silk strands in a stranding and twisting mode through one-step molding. Due to the fact that the sisal hemp core is formed by the sisal hemp silks in the stranding and twisting mode through the one-step molding, and two layers of steel wire rope strands are used for wrapping the sisal hemp core in a twisting mode to form the steel wire rope, diameter evenness is good, strength level and bearing capacity are improved, fatigue life is prolonged, service life is prolonged, and use demands of the high-rise high-speed elevator are satisfied.

Description

technical field [0001] The invention relates to a steel wire rope, in particular to a steel wire rope for a high-rise high-speed elevator, which is used for a high-rise high-speed elevator with a ladder speed greater than 2.5m / s and a floor height greater than 200m. Background technique [0002] In the case of increasingly tight land resources, buildings are becoming more and more space-oriented, the floors are getting higher and higher, and the lifting speed of elevators is getting faster and faster. Cost factors lead to smaller and smaller machine rooms for building elevators. Steel wire ropes put forward very high requirements, and the diameter of steel wire ropes is required to be thinner and smaller, and the carrying capacity is higher and higher. Elevator wire ropes with common national standard structures such as figure 1 As shown, it consists of a sisal core 1 and a layer of outer strands 2. Due to its low load-carrying capacity, low fatigue life, and poor diameter ...

AI Technical Summary

Problems solved by technology

Elevator wire ropes with common national standard structures such as figure 1 As shown, it consists of a sisal core 1 and a layer of outer strands 2. Due to its low bearing capacity, low fatigue life, and poor diameter uniformity, it is difficult to meet the requirements of high-rise high-speed elevators, especially difficult to meet the elevator speed greater than 2.5m / s. , The requirements for the use of high-rise high-speed elevators with a floor height greater than 200m
