Double-compaction steel wire rope for harbour machinery and manufacturing method of double-compaction steel wire rope

Abstract

The invention discloses a double-compaction steel wire rope for harbour machinery. The double-compaction steel wire rope comprises a steel core center strand, six steel core outer-layer strands and six outer-layer strands, the steel core outer-layer strands symmetrically wrap and twist the steel core center strand to form a steel core, the outer-layer strands symmetrically wrap and twist the steel core, a steel wire rope is a compaction rope, strands in the rope are in face contact, each outer-layer strand is a compaction strand, and steel wires in each strand are in face contact. Structure of the rope strands is in face contact through die extrusion, and the steel wire rope after being compacted is in face contact with a pulley, so that the double-compaction steel wire rope has ultrahigh breaking force and high wear resistance, extruding resistance and impact load resistance. Compared with those of steel wire ropes identical with the double-compaction steel wire rope in diameter and strength, bearing capacity is improved by 20%, and wear resistance is improved by about 25%; service life of the double-compaction steel wire rope is long, and correspondingly, running cost of the harbour machinery is reduced.

Description

technical field [0001] The invention relates to a steel wire rope, in particular to a double-compacted steel wire rope for port machinery and a manufacturing method thereof. Background technique [0002] At present, port equipment is increasing, and customers have higher and higher requirements for port steel wire ropes, especially the requirements for the load-bearing capacity and wear resistance of steel wire ropes. Although increasing the diameter of steel wire ropes will improve the load-bearing capacity and wear resistance of steel wire ropes, but It greatly increases the operating cost of the port equipment, and there will be problems such as mismatching with the pulleys of the equipment, which wastes materials. Contents of the invention [0003] The object of the present invention is to provide a double-compacted steel wire rope for port machinery and its manufacturing method, which has high bearing capacity, good wear resistance, extrusion resistance and impact loa...
