Multi-strand steel wire rope adds high flexibility and high filling factor steel wire rope

Abstract

The invention discloses a high-flexibility steel wire rope with seven strands of steel cores, and particularly relates to a steel wire rope with high flexibility and high filling coefficients increased by multi-strand steel wire rope bodies. The steel wire rope is formed by knitting and entwisting steel wires, and the steel wires are in point contact. The high-flexibility steel wire rope with the seven strands of steel cores is characterized by comprising an outer-layer strand and metal cores, each rope strand of the outer-layer strand, an inner-layer strand and the metal cores is formed by knitting and entwisting seven steel wires, each metal core is one steel wire, and the strand face is six steel wires. The breaking fore of the steel wire rope is improved on the basis of a common steel wire rope, the tensile strength of the steel wire rope is increased, meanwhile, attraction and friction between inner-layer rope strands are eliminated, the density between the rope strands is increased, the steel wire rope is more compact and wear resistant, the use cycle of the steel wire rope is prolonged, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to the field of steel wire ropes, in particular to a high flexibility steel wire rope. Background technique [0002] Steel wire rope is a kind of widely used metal product. Its structure is a flexible rope twisted by multiple thin steel wires. The steel wire rope is twisted into strands by multi-layer steel wires, and then twisted by a certain number of strands with the core as the center. Spiral rope. In material handling machinery, it is used for lifting, pulling, tensioning and carrying. Steel wire rope has high strength, good anti-collision performance, high lifting load-bearing capacity and pulling load-bearing capacity, and is widely used in various fields. There are various structures of steel wire, such as 6*36, 6*37, 18*7, etc. These structures have many strands of steel wire rope, are heavy in weight, are not resistant to impact and corrosion, and have poor anti-collision performance. The steel wire rope with conventio...

AI Technical Summary

Problems solved by technology

There are various structures of steel wire, such as 6*36, 6*37, 18*7, etc. These structures have many strands of steel wire rope, are heavy in weight, are not resistant to impact and corrosion, and have poor anti-collision performance. The steel wire rope with conventional structure is still structurally unstable. Defects

The rope strands are circular, and the rope strands are tangent to each other. The gap between the rope strands is relatively large. There is inevitably gravity and friction between the inner wire ropes, which reduces the compactness between the strands and greatly affects the life of the wire rope.
