Abstract

A steel wire rope for a crane comprises a central strand, four inner layer strands, four filling strands and eight outer layer strands. The central strand is entwisted by the inner layer strands in a symmetrically wrapping manner, an outer gap is arranged between each two adjacent inner layer strands, the filling strands are positioned inside outer gaps, the outer layer strands are symmetrically entwisted on the outermost side of the steel wire rope in a wrapping manner, and the inner layer strands, the filling strands and the outer layer strands are compacted strands in Warrington-Seale combined structures. The steel wire rope for a crane has the advantages of excellent anti-rotation performance and flexibility and stronger abrasion resistance, crumpling resistance, impact resistance and loading performance.

Description

The crane steel wire rope

Technical field

The utility model relates to a kind of metallic cable, specifically is meant the crane steel wire rope.

Background technology

At present, the domestic linear contact lay wire rope that generally uses all exists the characteristics that ABRASION RESISTANCE is not strong, steel cable is harder as 6 * 29FI+IWR, 6 * 36SW+IWR etc., though and 35W * 7 multistrand ropes such as grade are soft, ABRASION RESISTANCE is not strong, the characteristics that crush resistance is not strong.National standard requires the rupture pull force coefficient of steel wire rope to have only 0.36, but because the handling weight of crawler crane is increasing at present, require the minimum breaking force of load-bearing wires rope increasing, if select the steel wire rope of said structure for use, then wirerope diameter is too thick, and the design of 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 rupture pull force height, the crane steel wire rope of wear-resisting, anti-extruding, softness.

The technical scheme that solves the problems of the technologies described above is:

The crane steel wire rope, comprise central strand, 4 internal layer thighs, 4 filling thighs and 8 outer layer strand, described internal layer thigh wraps symmetrically twists with the fingers described central strand, 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; Described internal layer thigh, fill strand and outer layer strand is that Wa Lin gulps down-the compacting thigh of the fabricated structure of Xi Lushi.

Described central strand comprises 7 steel wires, wherein 6 steel wires symmetrically, be line and wrap the sth. made by twisting core wire touchingly.

Described internal layer thigh, filling thigh and outer layer strand all are divided into three layers, and its center section of steel wire is the regular pentagon shape; 5 steel wires of internal layer are face and wrap the sth. made by twisting core wire touchingly; There are 10 steel wires in the middle level, and wherein 5 thick wires are the recess that face embeds adjacent 2 steel wire of internal layer touchingly, and 5 finer wires are face and wrap the bossing of twisting with the fingers at 5 steel wire of internal layer touchingly respectively; Outer 10 steel wires symmetrically, be face and wrap touchingly and twist with the fingers the middle level.

Adopt disposable twisting to form when closing rope, then adopted the best fit of " FS " filled type and Xi Lushi structure between thigh and the thigh, the internal layer thigh is identical with filling strand radical, and the outer layer strand radical is internal layer thigh, the twice of filling thigh; Each personal share is rationally separated every thigh by noseplate on finished car, through behind the pre-former, tight with special line ball mold pressing, the post-formers of taking turns through too much group are eliminated the residual stress in the thigh more again, effectively reduced the construction of wire rope elongation, make it both guarantee the anti-verticity and the flexibility of multistrand rope, have stronger ABRASION RESISTANCE, crush resistance and shock resistance, load performance again.Common linear contact lay wire rope national standard rupture pull force coefficient is 0.36 at present, and the rupture pull force coefficient of the utility model steel wire rope reaches 0.44, improves about 22%, and handling weight is bigger, and rope footpath and crane facility need not strengthen.

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.

Embodiment 1

The crane steel wire rope, model is 16FS * K26WS+1 * 7-￠ 18mm, comprise central strand 1 (￠ 1.8mm), internal layer thigh 2 (￠ 3.8mm), fill gang 3 (￠ 1.95mm) and outer layer strand 4 (￠ 4.85mm), it is a multistrand rope, have 17 strands, strand with the thigh between contact condition be that line contacts, " FS " is filled type and the cooperating of Xi Lushi structure, be that internal layer thigh 2 wraps sth. made by twisting central strand 1 symmetrically, 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; Wherein, internal layer thigh, filling thigh are 4 * K26WS, and outer layer strand is 8 * K26WS." FS " formula structure of steel wire rope is filled up gap between the thigh with the mode of filled type, improves the effective area of steel wire rope, increases a steel wire rope ABRASION RESISTANCE thereby increase a burst footpath with Xi Lushi.

Further describe, central strand 1 comprises 7 superfine round wires, wherein 6 steel wires symmetrically, be line and wrap the sth. made by twisting core wire touchingly, have the advantages that the steel wire number is few, the steel wire contact condition is relatively stable, and flexibility is good.Internal layer thigh 2, fill strands 3 and outer layer strand 4 all be divided into three layers, for " WS " promptly watt woods gulp down-fabricated structure of Xi Lushi, its center section of steel wire is the regular pentagon shape; 5 steel wires of internal layer are face and wrap the sth. made by twisting core wire touchingly; There are 10 steel wires in the middle level, and wherein 5 thick wires are the recess that face embeds adjacent 2 steel wire of internal layer touchingly, and 5 finer wires are face and wrap the bossing of twisting with the fingers at 5 steel wire of internal layer touchingly respectively; Outer 10 steel wires symmetrically, be face and wrap touchingly and twist with the fingers the middle level.Wa Lin gulps down-the compacting thigh of the fabricated structure of Xi Lushi, can guarantee the softness of steel wire rope, and can guarantee the ABRASION RESISTANCE of steel wire rope again.
