Square eight-strand torsion-resistant steel wire rope

Abstract

The invention discloses a square eight-strand torsion-resistant steel wire rope which comprises six inner-layer rope strands and six outer-layer rope strands. The six inner-layer rope strands are arranged annularly, and the twisting direction is leftward. A central rope strand is also arranged at a central gap of the six inner-layer rope strands, and the periphery of the central rope strand is also provided with six cotton-linen woven strips subjected to grease soaking treatment. In the square eight-strand torsion-resistant steel wire rope, a sponge core layer is also arranged between the sixinner-layer rope strands and the six outer-layer rope strands, when the grease amount in the cotton-linen woven strips is excessively saturated, a large amount of grease is extruded out of the steel wire rope through slight extrusion, and grease waste is caused. After the sponge core layer wrapping the inner-layer rope strands is arranged, excessive grease can be absorbed by the sponge core layerand can be secondarily utilized, excessive grease from the sponge core layer can be stored in a circular-arc portion, the outer-layer rope strands extrude the sponge core layer, the grease from a bentportion is extruded out, excessive grease from the circular-arc portion gradually flows to the bent portion, and the sustained use time of grease is prolonged.

Description

technical field [0001] The invention belongs to steel wire ropes, in particular to a square eight-strand anti-twist steel wire rope. Background technique [0002] Most of the existing steel wire ropes have circular cross-sections, which are easy to rotate and knot, and their flexibility and anti-corrosion and anti-rust functions are not good enough; while most of the existing anti-twist steel wire ropes are designed with cross-section It is a square structure, but the anti-twist wire rope of the existing structure only sets the structure into a square shape, but its flexibility, anti-corrosion, anti-rust and wear-resistant functions are weak, resulting in a short service life of the anti-twist wire rope; A fiber hemp core or a steel core is set in the middle. The fiber hemp core has the effect of increasing lubrication, anti-corrosion and anti-rust, but the strength is not enough and it is easy to be torn off; while the steel core can increase the strength, but it has no fun...

Problems solved by technology

[0002] Most of the existing steel wire ropes have circular cross-sections, which are easy to rotate and knot, and their flexibility and anti-corrosion and anti-rust functions are not good enough; while most of the existing anti-twist steel wire ropes are designed with cross-section It is a square structure, but the anti-twist wire rope of the existing structure only sets the structure into a square shape, but its flexibility, anti-corrosion, anti-rust and wear-resistant functions are weak, resulting in a short service life of the anti-twist wire rope; A fiber hemp core or a steel core is set in the middle. The fiber hemp core has the effect of increasing lubrication, anti-corrosion and anti-rust, but the strength is not enough and it is easy to be torn off; while the steel core can increase the strength, but it has no function of lubrication, anti-corrosion and anti-rust; another problem is The oil extrusion on the fiber hemp core often has two extremes. One is that the oil is too full, which is easy to squeeze out and cause waste; but the oil cannot be completely squeezed out, which also causes waste in the use of oil.
