Abstract
A steel wire rope for a crane telescopic arm structurally comprises a center strand, inner-layer strands, a filling strand and outer-layer strands, wherein the inner-layer strands are symmetrically wrapped and twisted on the center strand, the filling strand is positioned inside an outer gap between two adjacent inner-layer strands, and the outer-layer strands are symmetrically wrapped and twisted on the outermost side of the steel wire rope. As the structures of the rope strands are extruded by moulds into surface contact shapes and the steel wire rope is formed by wrapping and twisting three layers of the strands on one center strand, the steel wire rope is fine in rotation resistant performance, and has stronger wear resistance, crumpling resistance and impact load resistant performance.
Description
Technical field
The utility model relates to a kind of steel wire rope, specifically is meant the telescopic crane boom steel wire rope.
Background technology
Along with the crane industry competition is growing more intense, crane requirement specification is little, bearing capacity is big.Telescopic arm will carry the weight of telescopic arm and the weight of carrier with steel wire rope, and this just requires the telescopic arm breaking force of rope high especially.At present, telescopic crane boom is used 6 * 29Fi+IWR, 35W * 7 structure class steel wire ropes more, and these two kinds of steel wire ropes belong to linear contact lay wire rope, also are round-strand ropes.National standard requires the rupture pull force coefficient of steel wire rope to have only 0.36, but because the handling weight of crane is increasing at present, require telescopic arm to that is to say that with the bearing capacity of steel wire rope minimum breaking force is increasing, if select the said structure round-strand rope for use, then wirerope diameter is too thick, and the design of crawler crane is brought certain difficulty.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of ABRASION RESISTANCE, crush resistance and resistance to shock loads performance all good telescopic crane boom steel wire ropes.
The technical scheme that solves the problems of the technologies described above is:
The telescopic crane boom steel wire rope comprises central strand, internal layer thigh, fills thigh and outer layer strand, and described internal layer thigh wraps the sth. made by twisting central strand symmetrically, and described filling thigh is positioned at the external series gap of adjacent two internal layer thighs, and described outer layer strand is wrapped sth. made by twisting symmetrically in the steel wire rope outermost.
Further be improved to, the core wire cross section of described central strand and filling thigh is approximate regular hexagon shape, 6 section of steel wire of the skin of described outer layer strand are approximate trapezoid shapes and connect into ring by trapezoidal side edges, the trapezoidal end face of described 6 steel wires is connected with six contacts of described core wire respectively, the trapezoidal bottom of described 6 steel wires towards outside.
Moreover described internal layer thigh is a Seale, is surface contact state between its adjacent wires, and that 9 finer wires of described internal layer thigh and 9 thick wires divide from inside to outside is two-layer, bag is twisted with the fingers core wire symmetrically.
Moreover described outer layer strand is that Xi Lu-Wa Lin gulps down composite construction, is surface contact state between its adjacent wires.
Because the structure of rope strand is face contact shape through the mould extruding, has improved steel wire rope metal effective area, 35W * 7 steel wire ropes of contrast same size, intensity, this structure breaking force of rope has improved 28%.In use and the contact-making surface of elevator, pulley big, ABRASION RESISTANCE improves.Simultaneously, the steel wire rope of this kind structure is twisted with the fingers a central strand twisting by three layers of thigh bag and is formed, and its resistance rotation performance is good.In use the steel wire rope of this kind structure has stronger ABRASION RESISTANCE, crush resistance and resistance to shock loads performance, and can improve more than 20% service life.
Central strand, internal layer thigh, filling thigh and outer layer strand all adopt the mould distortion when producing, be squeezed into face contact thigh, close rope then, have so just improved the whole rope rupture pull force of steel wire rope greatly, improve the bearing capacity of crane.

Mark is illustrated as among Fig. 1-5, and 1 central strand, 2 internal layer thighs, 3 are filled thigh, 4 outer layer strand.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1-5, the telescopic crane boom steel wire rope comprises central strand 1, internal layer thigh 2, fills thigh 3 and outer layer strand 4, and internal layer thigh 2 wraps symmetrically twists with the fingers central strand 1, filling thigh 3 is positioned at the external series gap of adjacent two internal layer thighs 2, and outer layer strand 4 is wrapped symmetrically and twisted with the fingers in the steel wire rope outermost.
The core wire cross section of central strand 1 and filling thigh is approximate regular hexagon shape, 6 section of steel wire of the skin of outer layer strand 4 are approximate trapezoid shapes and connect into ring by trapezoidal side edges, the trapezoidal end face of 6 steel wires is connected with six contacts of core wire respectively, the trapezoidal bottom of 6 steel wires towards outside.
Its preparation method is:
Arranged steel wire by noseplate twisting with the fingers on strand car, mouthful be compacted to steel wire rope and be deformed to desired structure, effectively eliminated the stress of thigh again through post-former, be received on the I-beam wheel then with the wolfram steel mould through closing up.With the mode of production of die drawing, when twisting with the fingers thigh, carry out (cold-)drawn (steel)wire rope rope strand with mould, a change strand interior wire shape makes it to be face contact shape, is prepared into central strand 1, filling thigh 3, the outer layer strand 4 that the internal layer thigh 2 of Seale and Xi Lu-Wa Lin gulp down composite construction.
When closing rope, each personal share is arranged by noseplate on finished car, through pre-former, compresses by closing up mouth again, effectively eliminates the stress of thigh again through post-former, is received on the I-beam wheel then.
Because the structure of rope strand is face contact shape through the mould extruding, has improved steel wire rope metal effective area, 35W * 7 steel wire ropes of contrast same size, intensity, this structure breaking force of rope has improved 28%.In use and the contact-making surface of elevator, pulley big, ABRASION RESISTANCE improves.Simultaneously, the steel wire rope of this kind structure is twisted with the fingers central strand 1 twisting by three layers of thigh bag and is formed, and its resistance rotation performance is good.In use the steel wire rope of this kind structure has stronger ABRASION RESISTANCE, crush resistance and resistance to shock loads performance, and can improve more than 20% service life.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
