Steel wire rope core for elevators and making method thereof

Abstract

The invention provides a steel wire rope core for elevators and a making method thereof. The steel wire rope core is mainly prepared from the following raw materials, by weight, 30-35 parts of polyester fibers, 15-20 parts of polyethylene fibers, 12-15 parts of aramid fibers, 8-10 parts of graphene, 8-10 parts of metal sulfide, 2-5 parts of silicon carbide, and 5-25 parts of filler. The performances of the steel wire rope core for elevators are better than those of imported rope cores. The steel wire rope core for elevators has high strength, high modulus, high density and good oil absorption performance, has the advantages of high diameter uniformity, high bending fatigue resistance, high abrasion resistance, high resistance to chemical corrosion and the like, and is a novel energy-saving and environment-friendly high-tech material. By adopting a steel rope made of the steel wire rope core, smooth operation of elevators is realized, and the fatigue life of the steel rope can be prolonged.

Description

technical field The invention belongs to the technical field of elevator supplies, in particular to a steel wire rope core for an elevator and a manufacturing method thereof. Background technique Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take people or carry goods, and is widely used in shopping malls, hotels, office buildings and high-rise residential buildings. The steel wire rope is one of the most important components of the elevator, and the steel wire rope core is the part with the heaviest bearing force in the steel wire rope. Therefore, its various properties have a great influence on the service life of the steel wire rope. CN103745779A discloses a multi-purpose composite rope core, comprising an optical fiber unit (optical cable), a sleeve and a fiber / resin composite rod (cable core); Composition; the sleeve is a high-temperature-resistant high-toughness polymer materia...

AI Technical Summary

Problems solved by technology

For elevators with high frequency of use and high speed, the service life and diameter uniformity of the wire rope are higher than those of ordinary elevator wire ropes. Elevators using ordinary sisal core wire ropes will affect ride comfort due to fluctuations in wire rope diameter. Elevators with steel core wire ropes will have a shorter service life due to poor oil storage performance of the wire ropes, and have higher maintenance requirements
