Abstract

The utility model discloses a double-compaction steel wire rope used for a crane. The double-compaction steel wire rope used for the crane structurally comprises central strands, inner-layer strands, filling strands and outer-layer strands, wherein the inner-layer strands symmetrically wrap and twist the central strands; the filling strands are positioned in an outer gap between two adjacent inner-layer strands; the outer-layer strands are symmetrically wrapped and twisted on the outmost side of the steel wire rope; and the steel wires of the outer-layer strands are connected in a surface contact status and are twisted. Because the structure of the outer-layer strands is extruded by a mould to be in the surface contact status, the metal effective area of the steel wire rope is improved. Meanwhile, because the steel wire rope is extruded by a whole rope, the strands in the steel wire rope are in the surface contact status, the contact area between the strands and a pulley is big when the steel wire rope is used, the abrasion resistance of the double-compaction steel wire rope is improved, and the double-compaction steel wire rope has a good rotation resistance performance.

Description

Crane is with two compacting steel wire ropes

Technical field

The utility model relates to a kind of steel wire rope, is meant that specifically crane is with two compacting steel wire ropes.

Background technology

At present, crane is used DL1315HK structure class steel wire rope more, and the rupture pull force coefficient of this steel wire rope is 0.44.Because at present the load capacity of crane for hoisting is increasing, also increasingly high to the requirement of the minimum breaking force coefficient of steel wire rope, if select the round-strand rope of said structure for use, wirerope diameter is too thick, and this design to crane brings certain difficulty.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides the good crane of a kind of rupture pull force height, ABRASION RESISTANCE and anti-extruding property with two compacting steel wire ropes.

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

Crane is with two compacting steel wire ropes; Comprise central strand, internal layer thigh, fill thigh and outer layer strand; Said internal layer thigh wraps symmetrically twists with the fingers said central strand, and said filling thigh is positioned at the external series gap of adjacent two internal layer thighs, and said outer layer strand is wrapped sth. made by twisting symmetrically in the steel wire rope outermost;

Further, said central strand comprises 1 core wire, 18 thick wires and 6 finer wires; 6 said thick wires wrap symmetrically twists with the fingers said core wire, and 6 said finer wires are positioned at the external series gap of adjacent two thick wires, and 12 said thick wires wrap sth. made by twisting symmetrically in the central strand outermost.

Further, said internal layer thigh comprises 1 core wire, 10 finer wires, 5 middle finer wires and 10 thick wires; 5 said finer wire bags are twisted with the fingers said core wire, and its outer staggered bag is twisted with the fingers and is provided with 5 middle finer wires and 5 finer wires, and 10 said thick wires wrap sth. made by twisting symmetrically in internal layer thigh outermost.

Further, said filling thigh comprises core wire and 6 cover wires; Said 6 cover wires wrap the sth. made by twisting core wire symmetrically.

Further, said outer layer strand is twisted with the fingers 1 core wire by 6 cover wires symmetry bag and is the face contact shape system of twisting with the fingers and forms.

Further, said crane contacts shape with being face between two compacting strand wires and the thigh.

When the production outer layer strand, carry out (cold-)drawn (steel)wire with mould and restrict, change wire shape in the outer layer strand, make to be face contact shape in the outer layer strand between the steel wire, close rope with central strand, internal layer thigh and filling thigh then.

Then, again steel wire rope is pushed, be face and contact shape between the thigh that makes steel wire rope and the thigh.

Because the structure of outer layer strand is face contact shape through the mould extruding, improved the metal effective contact area of steel wire rope skin with pulley, ABRASION RESISTANCE is good.Simultaneously, because steel wire rope is through extruding, is face and contacts shape in the rope strand with between the thigh; The compaction-strand steel wire rope of contrast same size, structure; Said steel wire rope internal structure is tightr, and rupture pull force coefficient raising 9.09%, ABRASION RESISTANCE improve 25%, in use; The steel wire rope of this kind structure has stronger crush resistance, and can improve more than 30% service life.

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Embodiment 1

Shown in Fig. 1-5; Crane comprises central strand 1, internal layer thigh 2, fills thigh 3 and outer layer strand 4 with two compacting steel wire ropes, 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 symmetry bags are twisted with the fingers in the steel wire rope outermost.

Central strand 1 comprises 1 core wire, 18 thick wires and 6 finer wires; 6 thick wires wrap the sth. made by twisting core wire symmetrically, and 6 finer wires are positioned at the external series gap of adjacent two thick wires, and 12 thick wires wrap the outermost of sth. made by twisting in central strand 1 symmetrically.

Internal layer thigh 2 comprises 1 core wire, 10 finer wires, 5 middle finer wires and 10 thick wires; 5 finer wire bags are twisted with the fingers 1 core wire, and its outer staggered bag is twisted with the fingers and is provided with 5 middle finer wires and 5 finer wires, and other has 10 thick wire symmetry bags to twist with the fingers the outermost at internal layer thigh 2.

Fill thigh 3 and comprise 1 core wire and 6 cover wires; 6 cover wires are twisted with the fingers core wire symmetrically.

Outer layer strand 4 is the face contact shape system of twisting with the fingers by 1 core wire of 6 cover wire symmetry bag sth. made by twisting and forms.
