Description

A kind of high intensity electric traction rope

Technical field

The utility model belongs to rope technique field, is related to a kind of high intensity electric traction rope.

Background technology

In power construction, during electric power cable unwrapping wire, there are steel wire rope, Di Nima ropes, Du as what pull rope was commonly used Nation restricts, silk insulating cord, polyamide fibre insulating cord etc., and steel wire rope itself is heavier, and it is difficult to carry unfolding, during field work, required machinery, Personnel are more, steel wire rope insulating properties extreme difference, occur causing human casualty accident in power line construction.Enlightening Nima rope and Du Pont Cord is to apply more electric traction rope at present, and good with flexibility, in light weight, tension intensity is extremely strong, and anti-ageing property is excellent, absolutely Edge, it is wear-resisting the advantages that.But power circuit construction operating mode becomes increasingly complex now, the requirement to electric traction rope is also more next It is higher.Existing enlightening Nima rope and Du Pont's cord also wear out seriously in severe construction environment, use meeting after a period of time Generation phenomenon of rupture, influences construction safety.

The content of the invention

Goal of the invention：In view of the shortcomings of the prior art, the utility model provides a kind of intensity height, in light weight, moistureproof, insulation The good high intensity electric traction rope of performance.

Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted in the utility model is as follows：

A kind of high intensity electric traction rope, including total rope strand and protective case, the protective case are wrapped in total rope strand outer layer, institute State total rope strand by six roots of sensation outer layer strands and the braiding of axial cord stock-traders' know-how or it is twisted form, total strands fit has polyureas； The outer layer strands or center rope strand include core rope, middle and outer layer strands, and the core rope is individual wire, described Middle is made up of six roots of sensation Du Pont silk or Di Nima fibers, the spiral shell of six roots of sensation Du Pont silk or Di Nima fibre compacts Rotation is wrapped in around core rope, and the outer layer strands are made up of 12 Du Pont's silks or Di Nima fibers, the outer layer strands 12 Du Pont's silks or Di Nima fibre compacts are spirally wound on around middle；The protective case is synthetic fibers Warp thread and the tubular braid that forms of weft yarns.

Wherein, the synthetic fibers of the protective case are polyvinyl alcohol fiber or polyacrylic fiber.

Wherein, the tubular braid is plain weave or oblique weavy grain road.

Wherein, the tubular braid axially spaced-apart is uniformly provided with the warp thread different from other warp thread colors, as Colour recognition line.

Wherein, the diameter of the core rope is at least twice of middle and outer layer strands respectively.

Wherein, the section of total rope strand can be circular, oblate or polygon.

Beneficial effect：Compared with prior art, the utility model has advantages below：

Pull rope of the present utility model is woven or is twisted together by outer layer strands and axial cord stock-traders' know-how and formed, and what is woven is total Protective case, outer layer strands and center rope strand are cased with by the high Du Pont's silk of light specific gravity, intensity or Di Nima fibrages outside rope strand Form, more rope strands, which are woven into total strands fit, polyureas so that the intensity of pull rope is more preferable, wear-resisting, and ageing-resistant performance is more excellent.

Brief description of the drawings

Fig. 1 is the cross-sectional structure schematic diagram of high intensity electric traction rope.

Fig. 2 is the outer layer strands of high intensity electric traction rope or the sectional view of center rope strand.

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 depicted in figs. 1 and 2, a kind of high intensity electric traction rope, including total rope strand and protective case 1, protective case 1 are wrapped in Total rope strand outer layer, total rope strand by six roots of sensation outer layer strands 2 and a center rope strand 3 it is woven or it is twisted form, total rope strand is cut Face can be circular, oblate or polygon, woven total strands fit have polyureas, and polyureas is by isocyanate component and amino A kind of elastomer substances of compound component reaction generation, have an excellent physicochemical property, high anti-tensile impact strength, soft Toughness, wearability, prevent wet and slippery, ageing-resistant, anticorrosion.Rope strand intensity filled with polyureas is higher, and wearability is more preferable.

The tubular braid that protective case 1 forms for the warp thread and weft yarns of synthetic fibers, the synthetic fibers of protective case 1 are Polyvinyl alcohol fiber or polyacrylic fiber, tubular braid are plain weave or oblique weavy grain road.Tubular braid axial direction Evenly spaced to be provided with the warp thread different from other warp thread colors, as colour recognition line, the overall color of protective case is white Color, colour recognition line can be it is red, blueness or other the color of sharp contrast is formed with protective case body color.

Outer layer strands 2 or the structure of center rope strand 3 are identical, are made up of core rope 4, middle 5 and outer layer strands 6, core Rope 4 is individual wire, and middle 5 is made up of six roots of sensation Du Pont silk or Di Nima fibers, six roots of sensation Du Pont silk or Di Nima Fibre compact is spirally wound on around core rope 4, and outer layer strands 6 are made up of 12 Du Pont's silks or Di Nima fibers, outer layer 12 Du Pont's silks of rope strand 6 or being spirally wound on around middle 5 for Di Nima fibre compacts, the diameter of core rope 4 It is at least twice of middle 5 and outer layer strands 6 respectively, the braiding of multilayer rope strand so that the intensity of pull rope is higher, Tensile property is more preferable, increases the service life.

Enlightening Nima fiber and Du Pont's silk are that proportion is most light in the world at present, the higher high-performance fiber of intensity, pressure-resistant insulation, Same diameter, it is to live across optimal product at present with 1/7 of its weight of intensity less than steel wire rope.

Pull rope of the present utility model is woven or is twisted together by outer layer strands and axial cord stock-traders' know-how and formed, and what is woven is total Protective case, outer layer strands and center rope strand are cased with by the high Du Pont's silk of light specific gravity, intensity or Di Nima fibrages outside rope strand Form, more rope strands, which are woven into total strands fit, polyureas so that the intensity of pull rope is more preferable, wear-resisting, ageing-resistant performance is more excellent.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
