Abstract

The utility model provides a six-strand forged wire rope, which comprises a wire rope core and six strands on the circumference, a relatively flat outside surface is formed on the circumferential surface of each strand, close surface contact state exists between the strands of the wire rope, cross section of each strand is sector shape. The utility model is characterized in that the six-strand forged wire rope has stable steel wire position and overall structure among forged wire ropes, metal density factor and rupture pulling force of the wire rope is about 10% higher than the same size of round strand wire rope, residual twisting stress of finished product wire rope is small, non-looseness performance is good, anti-wear performance and anti-fatigue performance of wire rope is enhanced, service life can be extended by one to two times generally. Since the structure extension of six-strand forged wire rope is reduced, the rope can be used as wire rope for overhead ropeway carrying rope, guy rope, and automobile crane telescopic arm. Six-strand forged wire rope can be used in important places of different industries.

Description

Six strands of forge wire ropes

Technical field

The utility model relates to a kind of steel wire rope, particularly a kind of six strands of forge wire ropes.

Background technology

General six strands of forge wire ropes contain original rope strand structure has Xi Lushi, Wa Lin to gulp down formula, the combined type steel wire rope in interior a plurality of kinds.Six strands of forge wire ropes are steel wire ropes with directionality that the industry of interna-tional date line material products is puted forth effort to research and develop, apply.Also be a plurality of industrial departments of China one of the principal items of huge fund import steel wire rope that spare no expense in recent years.

Still the professional standard that does not have forge wire rope at present both at home and abroad.The famous wire fabrication enterprise of industrially developed country such as American and Britain, Germany does not have comparatively complete product system yet, only has one at most, two kind of constructed products.

Domestic research and development to six strands of forge wire ropes at present are in the primary stage.

Construction of wire rope, specification directly have influence on its serviceability and life-span, the steel wire rope of general technology twisting shows not wear-resisting performance under conditions such as inclined shaft hoisting, therefore in the use phenomenon that shifts to an earlier date fracture of wire can be arranged, fracture of wire quantity transfinites and must scrap and substituted more.

Also there is structural unstable defective in general structure steel wire rope, inevitably has the twisting residual stress, and the steel cord structure in the use destroys in advance, twisting residual stress, serviceability and the life-span that all can reduce steel wire rope greatly.

General structure steel wire rope also can be low because of the density metal coefficient, breaking force of rope is little, have a strong impact on its use, have to strengthen wirerope diameter, or the tensile strength of raising steel wire rope, but these measures will be subjected to the restriction of equipment volume and Wire Rope Production factor, and these measures are subjected to the restriction of existing producing technique of steel cable possibility again.

Summary of the invention

For solving the problem that exists in the above-mentioned technology, the purpose of this utility model is to propose one forge wire rope, the wire rope core that has changed original steel wire rope is contacted by line with rope strand and becomes the face contact, overcome original fracture of wire, not wear-resisting, disadvantage such as the life-span is low, improved the applicability of six strands of forge wire ropes.

For achieving the above object, the technical solution adopted in the utility model provides a kind of six strands of forge wire ropes, comprise wire rope core and the six roots of sensation rope strand that is enclosed in its periphery by steel wire rope, wherein: the outer peripheral face of described every rope strand is formed with the outer surface of an opposed flattened, be surface contact state closely between the rope strand of described steel wire rope, the cross section of described every rope strand is fan shape.

The wire rope core of described steel wire rope is a kind of of fiber wire rope core or steel core.

Effect of the present utility model is that these six strands of forge wire ropes are owing to the position and the overall structure of steel wire in forge wire rope are stable, the density metal coefficient height of steel wire rope, density metal coefficient and rupture pull force than same specification round-strand rope are high by about 10%, the twisting residual stress of finished product steel wire rope internal memory is little, not loose performance is good, improve the wear resistance and the fatigue performance of steel wire rope, generally can improve 1-2 service life doubly.Because the structural stretch of six strands of forge wire ropes reduces, help as aerial cableway ropeway carrying-rope, guy wire, autocrane telescopic arm steel wire rope.The scope of application of six strands of forge wire ropes can satisfy the demand of the multiple important use of a plurality of different industries, the drifting in can be extensively supporting with guy wire, autocrane lifting and telescopic arm, crawler crane, harbour handling operation, port machine at rotary drilling rig, aerial cableway ropeway carrying-rope, vertical shaft cage guide, inclined shaft hoisting, power shovel lifting and guy wire, bucket wheel machine, the petroleum gas drilling, drags for oil, drags for multiple occasion such as husky operation, lumber and use.

The specific embodiment

Reaching embodiment in conjunction with the accompanying drawings is illustrated six strands of forge wire ropes of the present utility model.

As shown in Figure 1, six strands of forge wire ropes of the present utility model, comprise wire rope core 1 and the six roots of sensation rope strand 2 that is enclosed in its periphery by steel wire rope, the outer peripheral face of described every rope strand 2 is formed with the outer surface 3 of an opposed flattened, be surface contact state closely between the rope strand 2 of described steel wire rope, the cross section of described every rope strand 2 is fan shape.

The wire rope core 1 usable fibers wire rope core of described steel wire rope also can be made of steel core.

The utility model is to realize like this.

At first process the rope strand of steel wire rope, control the twisting quality of round-strand rope well, this has bigger influence to the forge wire rope quality that following process forms.The wire rope core 1 usable fibers wire rope core of steel wire rope is compiled twisting and is done, and as natural fabric-rope made of hemp, artificial fibre etc., also can make of steel wire twisting steel wire rope.Because the purposes difference, the amount of the forging difference of steel wire rope, the inboard steel wire in every steel wire rope rope strand 2 can be indeformable substantially.During distortion, the deflection of steel wire of internal layer also is significantly less than cover wire.Steel wire in the steel wire rope and rope strand are deformed so that produce an opposed flattened and wear-resisting outer surface 3 through forging, and are rendered as fan-shaped through the every strand wire that forges.The wire rope core 1 of steel wire rope has distortion or indeformable substantially slightly.The every rope strand 2 that makes steel wire rope is surface contact state closely.The surface stress of these six strands of forge wire ropes is tending towards rationally, the residualinternal stress that exists in the harmful twisting process of steel wire rope serviceability reduced significantly,

Confirm that through a large amount of practice tests these six strands of forge wire rope products can fully satisfy different industries user's instructions for use.
