Abstract

The utility model discloses a steel wire rope. The steel wire rope is characterized by comprising a sub rope and an outer layer of rope, wherein the sub rope comprises a central strand, 6 inner layer of strands and 12 outer layer of strands; the sub rope has a Warrington structure among layers; and the outer layer of rope comprises 16 strands of steel wire ropes uniformly distributed at the periphery of the sub rope; and the outer layer of rope and the sub rope are in point contact. The steel wire rope is good in flexibility and strong in abrasive resistance, anti-beating property and impact resistance.

Description

A kind of steel wire rope

Technical field

The utility model relates to a kind of metallic cable.

Background technology

Multistrand rope generally uses, on the important machinery such as tower machine and Spiral digging machine, particularly the tower machine of import and Spiral digging machine almost all adopt the multiply rope that does not reverse, on the one hand because multiply rope structure is special, ectonexine rope strand turning moment balance, be easy to cause the lax birdcage shape that forms of steel cable thigh in use, make the internal layer rope bear whole loads and cause serious overload; Be that these import equipments require the rupture pull force of steel wire rope far above national normal value on the other hand.Use at present common multistrand rope, as 19 * 7,35W * 7,36 * 7 etc., because relations such as structure and processing technology all can't reach and not rotate and flexibility height, superhigh intensity level, good, the anti-extruding of ABRASION RESISTANCE and the strong characteristic of resistance to impact.

Summary of the invention

The purpose of this utility model is, at the problems referred to above, proposes a kind of steel wire rope, and this steel wire rope ABRASION RESISTANCE is good, anti-fight and impact resistance is strong, flexibility is high.

For achieving the above object, the technical solution adopted in the utility model is: a kind of steel wire rope, it is characterized in that: comprise son rope and outer rope, described son rope comprises 1 central strand, 6 internal layer thighs and 12 outer layer strand, gulp down the formula structure for a watt woods between the layer of described son rope and the layer, described outer rope comprises that 16 strands are evenly distributed on son rope steel wire rope on every side, is the some contact between outer rope and the son rope.

Further, be the line contact in the son rope between the per share steel wire rope.

Further, the per share face contact thigh that all adopts 1*k7 in the steel wire rope.

For realizing above structure, preparation method of the present utility model may further comprise the steps:

Sth. made by twisting between described son rope and the skin to, adopt the son rope to twist with the fingers to opposite process means with outer rope, the torsional moment that makes rope with strand reverse the balance of making a concerted effort.

When making thigh, when twisting with the fingers thigh, adopt die drawing formula technology, choosing the distortion compression ratio is about 10%, round wire is entered the whole hard alloy mould, steel wire is out of shape in whole mould, and adopts the steel wire rope surface lubrication fat of constantly circulation to inject the preceding porch of whole mould, brings in the mould lubricated by steel wire, play the effect of the whole mould of cooling simultaneously, make the contact shape between the steel wire become planar contact.

When making the son rope, the intensity of steel wire level reaches 1960N/mm ²More than with the disposable effect that does not reach high rupture pull force of die drawing formula technology, so also must carry out secondary deformation.Here it is choose the distortion compression ratio be about 8%, the child rope is forged technical matters, then the child rope is evenly coated surface lubrication fat.

When the making steel wire rope, son is restricted as wire rope core, and outer layer strand process pre-former uses the line ball mold pressing tight again, and the post-formers that group is taken turns more through how are eliminated the residual stress in the thigh again, have effectively reduced the construction of wire rope elongation, evenly coat surface lubrication fat then.

The beneficial effects of the utility model are as follows:

1. crush resistance and shock resistance, load performance are strong, rupture pull force coefficient height, national standard multistrand rope rupture pull force coefficient is 0.36 at present, this steel wire rope reach 0.46, improved about 28%.

2. the son rope has adopted " W " Wa Lin to gulp down formula structure line contact shape, and the son rope contacts shape with outer rope point, makes steel wire rope keep the flexibility of multiply.

3. make steel wire rope tightr by the die drawing formula with combining of the technology of forging, increased the ABRASION RESISTANCE and the crush resistance of steel wire rope, the service life of having improved steel wire rope.

4. effectively reduced the construction of wire rope elongation, improved the tightness and the glacing flatness of steel wire rope, further improved verticity, effectively control causes the lax birdcage shape phenomenon that forms of steel cable thigh in use.
