Resin coating metal core steel wire rope for superspeed elevator

Abstract

The invention discloses a resin coating metal core steel wire rope for a superspeed elevator. The resin coating metal core steel wire rope comprises a center strand, eight inner-layer stands are symmetrically twisted outside the center strand, the eight inner-layer strands are coated with a resin coating, and eight outer-layer strands are symmetrically twisted outside the resin coating. The resin coating metal core steel wire rope for the superspeed elevator is formed by twisting the eight outer-layer strands outside a resin metal rope core, and the resin metal rope core is formed by evenly wrapping a metal rope core by resin. The steel wire rope of the structure has high shock resistance and diameter uniformity, and the bearing capacity of the steel wire rope is improved. Compared with an elevator steel wire rope with the same diameter and strength grade on the current market, the diameter uniformity of the steel wire rope of the structure is improved by 15%, the shock resistance of the steel wire rope is improved by 10%, and the bearing capacity of the steel wire rope is improved by 5%.

Description

technical field [0001] The invention relates to a steel wire rope for an elevator, in particular to a resin-coated metal core steel wire rope for an ultra-high-speed elevator. Background technique [0002] At present, in the elevator industry, as the height of the floor rises, the running speed of the elevator is gradually accelerated, and the requirements for the steel wire rope are getting higher and higher. Some elevators with heavy load and fast running speed require the diameter uniformity, bearing capacity and The flexibility and performance are all good, and although increasing the diameter of the wire rope will increase the load-bearing capacity of the wire rope, it will greatly increase the operating cost of the elevator and waste materials. Contents of the invention [0003] The purpose of the present invention is to provide a resin-coated metal core steel wire rope for an ultra-high-speed elevator, which has the characteristics of good impact resistance, good li...
