Embodiment Construction

[0021] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0022] Such as figure 1 As shown, the micro-rotating steel wire rope for high-rise high-speed elevators includes outer strands 1, inner strands 2 and central strands 3. The number of inner strands 2 is 8 and is evenly twisted on the outside of the central strand 3. The outer strands 1 The number is 8 and the outer side of the inner layer strand 2 is evenly wrapped.

[0023] Such as figure 2 As shown, the outer layer strand 1 is a Xilu-style structure, with 1 central steel wire in the center, and an inner layer composed of 8 thin steel wires evenly wrapped and twisted on the outside of the central steel wire. The outer layer is composed of 8 thick steel wires on t...

Abstract

The invention discloses a micro rotating wire rope for a high-rise express elevator and a preparation method thereof. The wire rope comprises a central strand, 8 inner layer strands and 8 outer layer strands, wherein the 8 inner layer strands are uniformly twisted outside the central strand, and the 8 outer layer strands are uniformly twisted outside the inner layer strands. The preparation method of the wire rope comprises the following steps: stranding, eliminating the strand stress, and twisting to form the rope. Compared with the traditional elevator wire rope, the wire rope prepared by the method disclosed by the invention has the advantages of strong bearing capacity, favorable rotating property, low percentage of elongation and uniform diameter, and is suitable for high-rise express elevators.

Description

technical field [0001] The invention relates to a steel wire rope and a preparation method thereof, in particular to a micro-rotating steel wire rope for high-rise high-speed elevators and a preparation method thereof. Background technique [0002] Due to the rapid development of high-rise high-speed elevators, the elevator speed is getting higher and higher, and the requirements for steel wire ropes are also increasing. Ordinary elevators with 8*19S+NF structure including steel core and semi-steel core structure steel wire ropes can no longer meet the use of some high-rise high-speed elevators. The uniformity of the strips was also not good enough. Contents of the invention [0003] The object of the present invention is to address the above problems, to provide a micro-rotating steel wire rope for high-rise high-speed elevators and its preparation method, in order to obtain steel wire ropes for elevators with excellent bearing capacity and anti-rotation performance to m...
