Abstract

The utility model relates to a new construction is prevented turning round rope and is used wire rope, its characterized in that: prevent turning round centre that the rope used wire rope for middle sandwich layer (1), the periphery of middle sandwich layer (1) is equipped with eight four boundaries of a piece of land or a construction site steel wire thigh (2), a plurality of steel wire thigh (2) transposition is on middle sandwich layer (1) surface. This kind of new construction is prevented turning round rope and is used wire rope's middle sandwich layer is synthetic materials such as PP core, hemp center, yarn core, PU core, and perhaps above -mentioned materials compound forms, and it has replaced steel wire in the past, and the grease can be stored to middle sandwich layer, looks at and appraises structure than before, and its non -corrosibility ability and greasy property are better, and life is high, the periphery of middle sandwich layer is equipped with eight steel wire thighs of the four boundaries of a piece of land or a construction site, and the transposition of a plurality of steel wire thighs is on middle sandwich layer surface, and steel wire transposition back is compared with original sub -thread wire rope, and wire rope's compliance is better, and it is better to prevent turning round the rope reelability, prevents with the equal diameter that to turn round the whole rope breaking force of rope higher.

Description

A kind of new construction block span steel wire rope

Technical field

The utility model relates to a kind of block span steel wire rope of new construction, belongs to metallic article technical field.

Background technology

Block span steel wire rope is weaved into by braiding machine and is prevented turning round steel wire rope, and anti-steel wire rope of turning round drags electric wire when ultra-high-tension power transmission line stringing for holder, as pull rope, the guide rope of power circuit Poling Construction, ordinary steel rope also can be replaced to use as traction suspension rope.

Block span steel wire rope is in the past all by the sub-thread of steel wire primary twisting, its structure is simple, prevent turning round effect bad, the flexibility of steel wire rope is not high, to cause after weaving anti-, and to turn round steel wire rope reelability not good, whole rope rupture pull force is lower, and simultaneously steel wire rope in the past is all made up of steel wire, its anti-corrosive properties and greasy property poor.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide anti-turn round effective, flexibility is high, rupture pull force is high, the anticorrosion and good a kind of new construction block span steel wire rope of greasy property simultaneously.

The purpose of this utility model is achieved in that

A kind of new construction block span steel wire rope, the centre of described rope steel wire rope is intermediate core layer, and the outer of described intermediate core layer is arranged with four to eight steel strands, and described multiple steel strand is stranded in intermediate core layer surface.

Described steel wire rope is 4x19 type, and steel strand is 1x19 type, and wherein each steel strand has three-decker from inside to outside, and wherein innermost layer is single steel wire, and the second layer is six roots of sensation steel wire, and third layer is 12 steel wires, and in described compound steel silk, all gauges of wire are identical.

Described steel wire rope is 4x19S type, steel strand is 1x19S type, wherein each steel strand has three-decker from inside to outside, wherein innermost layer is the thickest single steel wire, the second layer is nine the thinnest steel wires, third layer is nine steel wires, and these nine gauges of wire are between innermost layer and second layer gauge of wire.

Described steel wire rope is 4x26WS type, steel strand is 1x26WS type, wherein each steel strand has four-layer structure from inside to outside, wherein innermost layer is the thinnest single steel wire, the second layer is five slightly thick steel wires, third layer is that five finer wires and five thick wires are intervally arranged and form, and outermost layer is ten thicker steel wires.

Described intermediate core layer is that PP core or hemp core or yarn core or PU core or above-mentioned material are composited.

A kind of new construction block span of the utility model has the following advantages:

The intermediate core layer of this kind of new construction block span steel wire rope is PP core, hemp core, yarn core, the synthetic materials such as PU core, or above-mentioned material is composited, it instead of steel wire in the past, intermediate core layer can store grease, compare original structure, its antiseptic property and greasy property better, high life, the outer of described intermediate core layer is arranged with four to eight steel strands, multiple steel strand is stranded in intermediate core layer surface, compared with original single-strand rope after steel strand is stranded, the flexibility of steel wire rope is better, block span reelability is better, the whole rope rupture pull force of the block span of equivalent diameter is higher.
