Abstract

The utility model discloses a kind of anti-torsion steel wire rope, including four strands of internal layer rope strands and four bursts of outer layer strands；Four strands of described internal layer rope strands are annular array, and twist direction is left-hand lay；And the twist direction of four described outer layer strands is right-laid, and four bursts of outer layer strands are divided into the peripheral gap of four strands of internal layer rope strands, the global sections of steel wire rope is shaped as square structure；Gap among four strands of internal layer rope strands is additionally provided with the inner fiber layer by grease immersion treatment；And it is provided with outer layer fiber layer between per share rope strand in four bursts of described outer layer strands two strands of internal layer rope strands adjacent thereto.When the utility model uses steel wire rope, inner fiber layer inside extruding makes its grease squeeze out lubrication in steel wire rope surface, increase rub proofness, and the unnecessary grease squeezed out can be absorbed by outer layer fiber layer again, it can prevent excess oil from directly being dripped after extruding with secondary use.

Description

A kind of anti-torsion steel wire rope

Technical field

The utility model belongs to steel wire rope, and in particular to a kind of anti-torsion steel wire rope.

Background technology

Existing steel wire rope is structure of some sections for circle mostly, and the easy rotation of such steel wire rope knots, and pliability It is all not good enough with antiseptic and rustproof function；And it is square structure that a kind of steel wire rope of existing anti-torsion is designed to section more, but The anti-torsion steel wire rope for being existing structure is only but its pliability, antiseptic and rustproof and wearability by structure setting squarely Can still exist, cause the service life of anti-torsion steel wire rope shorter.

Utility model content

The purpose of this utility model is in view of the deficienciess of the prior art, providing a kind of anti-torsion steel wire rope, its technical side Case is as follows：

A kind of anti-torsion steel wire rope, including four strands of internal layer rope strands and four bursts of outer layer strands；Four strands of described internal layer rope strands are ring Shape arranges, and twist direction is left-hand lay；And the twist direction of four described outer layer strands is right-laid, and four bursts of outer layer strands are divided into four The peripheral gap of stock internal layer rope strand, makes the global sections of steel wire rope be shaped as square structure；Among four strands of internal layer rope strands Gap is additionally provided with the inner fiber layer by grease immersion treatment；And the per share rope strand in four bursts of described outer layer strands is equal Outer layer fiber layer is provided between two strands of internal layer rope strands adjacent thereto.

Preferably, described internal layer rope strand is identical with the size structure of outer layer strands；Innermost layer is arranged on including one Core wire, six be looped around the steel wire of internal layer of core wire periphery, six be looped around it is outer in the space of steel wire of internal layer periphery Layer steel wire and six and the spaced nylon rope strand of cover wire.

Preferably, described core wire is identical with the external diameter of nylon rope strand；And described steel wire of internal layer and outer layer steel The external diameter of silk is identical；And the external diameter of described core wire is 3/5ths of the external diameter of steel wire of internal layer.

Preferably, the outside of described core wire, steel wire of internal layer and cover wire is coated with zinc layers.

Beneficial effect：The utility model has the advantages that：

(1) steel wire rope is divided into inside and outside two layers in the utility model, and internal layer rope strand is arranged on internal layer around arrangement, outer layer strands Rope strand periphery makes the section of steel wire rope be square structure, not twist ties when using steel wire rope；The middle part of internal layer rope strand The inner fiber layer of grease immersion treatment is set, and outer layer fiber layer is set between ectonexine rope strand, on the one hand so design increases Add the contiguity between ectonexine rope strand, increase tensile strength；On the other hand when using steel wire rope, inside is extruded Inner fiber layer makes its grease squeeze out lubrication on steel wire rope surface, increases rub proofness, and squeeze out it is unnecessary Grease can be absorbed by outer layer fiber layer again, can prevent excess oil from directly being dripped after extruding with secondary use；

(2) rope strand is made up of core wire, steel wire of internal layer and cover wire in the utility model, and structural arrangement is reasonable, is increased Add tensile strength, and be coated with zinc layers outside steel wire to increase antiseptic and rustproof function；And it is provided with outer layer strands interval Nylon rope strand, increase the overall bulk softness of steel wire rope, increase the service life of steel wire rope.

Brief description of the drawings

Fig. 1 is the utility model structure diagram.

Embodiment

Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, the present embodiment is with the utility model Implemented under premised on technical scheme, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality With new scope.

As shown in figure 1, a kind of anti-torsion steel wire rope, including four strands of internal layer rope strands 1 and four bursts of outer layer strands 2；Described four strands Internal layer rope strand 1 is annular array, and twist direction is left-hand lay；And the twist direction of four described outer layer strands 2 is right-laid, and four strands of outer layers Rope strand is divided into the peripheral gap of four strands of internal layer rope strands 1, the global sections of steel wire rope is shaped as square structure；In four strands Gap among layer rope strand 1 is additionally provided with the inner fiber layer 3 by grease immersion treatment；And four bursts of described outer layer strands Outer layer fiber layer 4 is provided between per share rope strand in 2 two strands of internal layer rope strands 1 adjacent thereto.

Described internal layer rope strand 1 is identical with the size structure of outer layer strands 2；Including a central steel for being arranged on innermost layer Silk 5, six is looped around the outer layer steel that the peripheral steel wire of internal layer 6, six of core wire 5 is looped around in 6 peripheral space of steel wire of internal layer Silk 7 and six and the spaced nylon rope strand 8 of cover wire 7.

Described core wire 5 is identical with the external diameter of nylon rope strand 8；And described steel wire of internal layer 6 and cover wire 7 is outer Footpath is identical；And the external diameter of described core wire 5 is 3/5ths of the external diameter of steel wire of internal layer 6.

The outside of described core wire 5, steel wire of internal layer 6 and cover wire 7 is coated with zinc layers.

Steel wire rope is divided into inside and outside two layers in the utility model, and internal layer rope strand is arranged on internal layer rope around arrangement, outer layer strands Stock periphery makes the section of steel wire rope be square structure, not twist ties when using steel wire rope；Set in the middle part of internal layer rope strand The inner fiber layer of grease immersion treatment is put, and outer layer fiber layer is set between ectonexine rope strand, on the one hand so design increases Contiguity between ectonexine rope strand, increase tensile strength；On the other hand when using steel wire rope, the interior of inside is extruded Layer fibrous layer makes its grease squeeze out lubrication in steel wire rope surface, increase rub proofness, and the unnecessary oil squeezed out Fat can be absorbed by outer layer fiber layer again, can prevent excess oil from directly being dripped after extruding with secondary use.
