A super-large-diameter cable-type steel wire rope

Abstract

A super-large-diameter cable type steel wire rope is formed by twisting six steel wire rope bodies around one single-cord metal core, wherein the single-cord metal core is of a 1*265 point-line contact structure; the structural formula of the steel wire rope bodies is 14*55SWS+6*35WS+IWR, and one main steel wire rope body of a six-cord structure is externally wrapped by fourteen outer layer ropes of a 55SWS structure by one layer and twisted to form one steel wire rope body. The steel wire rope is large in diameter, high in strength and complex in structure, the technical problem that a super-large-diameter steel wire rope with the diameter over 260 mm cannot be produced in China yet at present is solved, the domestic blank is filled up, and the requirement for high bearing capacity of salvage and anchoring of oceanographic engineering and large hoisting rigging can be met.

Description

technical field [0001] The invention relates to a super-large-diameter cable-type steel wire rope, which belongs to the technical field of metal products. Background technique [0002] The existing steel wire ropes are mainly divided into single-twist steel wire ropes and double-twist steel wire ropes according to the twisting type. The single-twist steel wire ropes are twisted once, the central steel wire is in a straight line, and the outer layer steel wires are in a spiral shape, such as single-strand ropes; double-twist steel wire ropes It is twisted twice, and it is twisted by multiple steel wire strands around a fiber core or steel core. The central steel wire of each strand is a primary helix, and the rest of the steel wires are a secondary helix. The problem existing in the existing steel wire rope is that the softness of the steel wire rope is poor, the size of the steel wire rope is small, the breaking force is small, and the diameter of the steel wire rope is gene...

AI Technical Summary

Problems solved by technology

The problem existing in the existing steel wire rope is that the softness of the steel wire rope is poor, the size of the steel wire rope is small, the breaking force is small, and the diameter of the steel wire rope is generally less than 200mm, which cannot meet the high load-bearing capacity requirements of marine engineering and large-scale hoisting slings for large-scale steel wire ropes with a diameter of 260mm or more.
