Fiber cable core structure for steel wire rope

Abstract

The invention relates to a fiber cable core structure for a steel wire rope, comprising a central strand and 4, 5, 6, 7 or 8 outer layer strands, wherein, the outer layer strands are tightly stuck to the surface of the central strand, are made by spiral spinning around the central strand and are evenly distributed on the surface of the central strand;and the central strand and the outer layer strands are both made by spiral spinning of a plurality of grass yarns or artificially synthesized fiber. The structure can improve the flexibility of the fiber cable core, increase inner oil content and bearing force for the steel wire rope strands and satisfy the requirement of the steel wire rope on the fiber cable core when the diameter of the fiber cable core exceeds 25 mm.

Description

technical field [0001] The invention relates to a fiber rope core structure of a steel wire rope. Background technique [0002] The rope core of the steel wire rope mainly includes two types of fiber rope core and metal rope core. (3) When the steel wire rope is subjected to collision, impact load and lateral extrusion during work, the fiber rope core can act as a buffer to weaken the damage of the dynamic load to the steel wire rope; (4) The grease in the core is squeezed into the steel wires in the strands for lubrication, so that the internal wear between the steel wires is greatly reduced; (5) the fiber rope core can also slightly increase the tensile capacity of the steel wire rope. [0003] The basic requirements for the fiber rope core are: (1) have a certain tensile strength and compressive strength; (2) have high flexibility; (3) have a certain corrosion resistance; (4) have a relatively high moisture content Low, poor hygroscopicity; (5) High oil immersion capaci...

AI Technical Summary

Problems solved by technology

[0005] When the diameter of the fiber rope core exceeds 25mm, the overall performance of the steel wire rope is affected due to poor flexibility, low oil content and insufficient support for the steel wire rope strands.
