Embodiment Construction

[0019] The technical solutions of the present invention will be further described below through specific embodiments.

[0020] In the present embodiment, a kind of manufacture method of high-rise elevator wire rope, it comprises the following steps:

[0021] Step 1, select the wire material: use 70# high-quality carbon steel for the center and inner layer steel wire, and use 45-60# high-quality carbon steel for the outer layer wire;

[0022] Step 2, one-time wire drawing: use the wire drawing machine for preliminary drawing of the selected wire to obtain the required specifications;

[0023] Step 3, heat treatment: heating and quenching the steel wire drawn for the first time, and then surface treatment to finally obtain a sorbite quenched steel wire.

[0024] Step 4, secondary wire drawing: the quenched steel wire obtained by the above heat treatment is drawn again, and after the wire drawing is completed, 2 groups of 14 mutually perpendicular pulley blocks are used to repea...

Abstract

The invention discloses a manufacturing method of steel wire ropes for high-rise elevators, comprising the following steps: a, selecting wires; b, drawing at a time; c, performing heat treatment; d, drawing at a second time; e, entwisting strands, entwisting the steel wires drawn at a second time according to needed structures and specifications to form outer layer strands and inner layer strands for the steel wire ropes and repeatedly bending after forming the strands to manufacture steel wire rope strands; f, entwisting center sub-ropes, packaging and entwisting 3 helm cores with 8 inner layer strands obtained in the step e to manufacture the centre sub-ropes of the steel wire ropes; j, entwisting the ropes, packaging and entwisting the centre sub-ropes obtained in the step f with 8 outer layer strands obtained in the step e to entwist the needed steel wire ropes, and repeatedly bending after forming the strands to manufacture the steel wire ropes. The steel wire ropes manufactured by using the manufacturing method of the steel wire ropes for the high-rise elevators have the advantage of good diameter uniformity; the elevators have the advantages of good comfort level and stability in the operation process; the steel wire ropes are suitable for the elevators used by high-rise buildings.

Description

technical field [0001] The invention relates to a method for manufacturing steel wire ropes, in particular to a method for manufacturing high-rise elevator steel wire ropes. Background technique [0002] During the operation of the elevator, it mainly depends on the friction between the elevator rope and the traction wheel to lift the elevator. At the same time, there are 6-8 traction wire ropes to lift the cabin. The wire rope and the traction wheel are in operation. Due to the uneven diameter of the wire rope, The instantaneous running linear speed of each steel wire rope is inconsistent, resulting in relative sliding of the steel wire rope and the traction sheave, causing the vibration of the elevator and reducing the service life of the steel wire rope and traction sheave. The higher the building using the stairs, the cumulative relative sliding The higher the probability, the more obvious the vibration of the elevator. At present, the elevator wire rope is mainly made ...
