Abstract

The utility model discloses a cable wire for a crane, which is characterized by comprising a metal rope core and six main-strand cable wires uniformly arranged around the metal rope core, wherein the metal rope core comprises a metal center strand and six metal rope core external-layer strands which wrap the metal center strand in a linear contacting way; each strand of cable wires of the metal rope core is pressing strands of 1*K7; and the metal rope core is contacted with the six main strands in a point contact way. The cable wire has high breaking tension, and is wearable, extrusion-resistance and soft.

Description

A kind of crane steel wire rope

Technical field

The utility model relates to a kind of metallic cable, particularly, relates to a kind of crane steel wire rope.

Background technology

At present, domestic generally use crane with steel wire rope as line contact structures such as 6 * 29FI+IWR, 6 * 31WS+IWR, 6 * 36WS+IWR exist all that flexibility is poor, crush resistance not by force, not wear-resisting characteristics, service life is short.Cause the frequent more change steel rope of user, increased user's cost.For solving this difficult problem, the ad hoc new structure steel wire rope of having counted, strand technology mode that adopts dotted line to contact, solution steel cable flexibility; Improve the whole rope rupture pull force and the crush resistance of steel wire rope with forging technology, isostructure diameter forge wire rope exceeds more than 15% than the whole rope rupture pull force of common linear contact lay wire rope, effectively raises the bearing capacity of steel wire rope.

Summary of the invention

The purpose of this utility model is that at the problems referred to above, the present utility model provides a kind of rupture pull force height, the crane steel wire rope of wear-resisting, anti-extruding, softness.

For achieving the above object, the technical solution adopted in the utility model is: a kind of crane steel wire rope, comprise metal core and be evenly distributed on metal core 6 main strand steel wire ropes on every side, metal core comprises 1 metal center thigh and is 6 metal core outer layer strand that line wraps sth. made by twisting metal center thigh touchingly, the per share steel wire rope of metal core is the compacting thigh of 1*K7, is the some contact between metal core and 6 main thighs.

Further, main strand steel wire rope is divided into 1 central hair, 6 internal layer silks, 12 median caudal filaments and 16 outer silks, described main strand of central hair section of steel wire is polygon-shaped, the internal layer silk is face and wraps sth. made by twisting central hair touchingly, 6 thick wires are the recess that face embeds adjacent 2 internal layer thigh steel wires touchingly in the median caudal filament, 6 finer wires are face, and the bag sth. made by twisting is at the bossing of 6 steel wire of internal layer respectively touchingly, and outer silk is a little to wrap touchingly twists with the fingers the internal layer thigh.

Adopt the preforming process means when twisting is metal-cored, its every thigh fully is out of shape, eliminate residual stress with special-purpose post-former then, make steel core straight; Close the outer 6 garden thighs of rope steel wire rope and carry out the helicity rotation round metal core, 6 main strand is rationally separated every thigh by noseplate on finished car, through behind the pre-former, the post-formers of taking turns through too much group are eliminated the residual stress in restricting more again, steel wire rope closes the rope back and adopts 5～8% rates of forging to forge technology, after forging processing, form four limit type fan types.Increased the effective area and the compactedness of steel wire rope greatly, reduced the construction of wire rope elongation, stablized the contact condition between each strand, made it have stronger ABRASION RESISTANCE, crush resistance and shock resistance, softness.When the steel wire rope selected for use with diameter, the load that it bore can be far above the value of prescribed by standard more than 15%, and the steel wire rope of this new structure is applicable to that work is frequent and has under the situation of impact load.

The utility model adopts the technology mode of dotted line contact, solves the steel cable flexibility; Improve the whole rope rupture pull force and the crush resistance of steel wire rope with forging technology, isostructure diameter forge wire rope exceeds more than 15% than the whole rope rupture pull force of common linear contact lay wire rope, effectively raises the bearing capacity of steel wire rope.Main strand of steel wire number of the present utility model is 35 steel wires, and this steel wire number is Duoed 6 than traditional filled type 29FI steel wire, and is better than this structurally flexible; Lack 1 than 36WS structure steel wire number, the steel wire rope ABRASION RESISTANCE is better like this.A design burst structure is (1+6+6/6,16), the thigh internal layer adopts a watt woods to gulp down the formula structure, this structural outside layers steel wire is made up of the different steel wire of thickness, and it has flexibility and stronger prehensile preferably, is convenient to the installation and the winding of steel wire rope, stock secondary twisting makes in the thigh steel wire of internal layer tightr and withstand voltage, adopt the lay pitch in 7～7.5 times of thighs footpaths when producing thigh, also make thigh both tight and soft, thereby strengthen the fatigue behaviour of steel wire rope.
