Abstract

The utility model discloses a filling type double-compaction hoisting steel wire rope, which comprises an outer layer and a center secondary rope. Outer-layer strands encircle to form the outer layer and symmetrically entwist the center secondary rope, the center secondary rope comprises a center strand and inner-layer strands, the inner-layer strands are uniformly distributed on the outer side of the periphery of the center strand, the outer-layer strands comprise center wires, inner-layer wires, filling wires and outer-layer wires, the outer sides of the center wires are surrounded by the inner-layer wires, the outer sides of the inner-layer wires are surrounded by the outer-layer wires, the filling wires are filled between the inner-layer wires and the outer-layer wires, the outer-layer strands and the center secondary rope are squeezed and combined to form a circular structure, and the outer-layer strands are in surface contact with the center secondary rope. The outer-layer strands are arranged on the outer side of the steel wire rope, the filling wires are filled in seams of the outer-layer strands, wear resistance and fatigue resistance of the steel wire rope are increased, and the filling type double-compaction hoisting steel wire rope has the advantages of long service life and simple structure.

Description

Lift heavy is with the two compacting steel wire ropes of filled type

Technical field

The utility model relates to a kind of lifting, handling rigging, particularly relates to a kind of steel wire rope.

Background technology

Along with China's rapid development of economy, every profession and trade has also proposed different instructions for uses to lifting rigging especially steel wire rope, has also quickened the more New steps of China harbour or other heavy industry hoisting and hanging steel wire rope, the general at present 6 strands contact steel wire rope that uses.The breaking force of rope coefficient of this structure is low, and bearing capacity is not high, and ABRASION RESISTANCE and resistance to shock loads performance are not enough, so service life is short, and safety coefficient is low.The design's steel wire rope improves common 6 strands contact steel wire rope, has improved the bearing capacity of steel wire rope, wear-resisting and resistance to shock loads ability, satisfies the demand of harbour and other heavy industry lifting use preferably.

The utility model content

The utility model has been to overcome the defective of prior art, and the lift heavy that a kind of long service life is provided is with the two compacting steel wire ropes of filled type.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

Comprise skin and middle center rope that outer layer strand surrounds; Center rope during said outer layer strand symmetry bag is twisted with the fingers, said middle center rope comprises central strand and internal layer thigh, said central strand periphery is evenly distributed with the internal layer thigh; Said outer layer strand comprises central hair, internal layer silk, fills silk and outer silk; The said central hair outside is surrounded by the internal layer silk, and the said internal layer silk outside is surrounded by outer silk, is filled with between said internal layer silk and the outer silk and fills silk; Said outer layer strand and middle center rope is extruded that to close rope circular, is face contact shape between said outer layer strand and the middle center rope.

Be extruded between said central strand and the internal layer thigh and be face contact shape.

Said central strand, internal layer thigh are 1 steel wire of 6 steel wire bags sth. made by twisting system of twisting with the fingers and form.

Said outer layer strand is approximate trapezoid.

Be extruded between said central hair, internal layer silk, filling silk and the outer silk and be face contact shape.

Compared with prior art, the utlity model has following beneficial effect:

In the outer layer strand slit of steel wire rope, insert and fill silk, improve the ABRASION RESISTANCE and the fatigue resistance of steel wire rope, thereby the service life of improving steel wire rope is simple in structure.

Description of drawings

Fig. 1 is the preceding lift heavy of the utility model extruding two compacting construction of wire rope sketch mapes of filled type;

Fig. 2 for the utility model lift heavy with the two compacting construction of wire rope sketch mapes of filled type;

Fig. 3 is the sketch map of the utility model outer layer strand.

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.

As shown in Figure 1, be lift heavy with the two compacting steel wire ropes of filled type, do not pass through the structure before the extrusion process.

Like Fig. 2, shown in Figure 3, lift heavy comprises skin and middle center rope that outer layer strand surrounds with the two compacting steel wire ropes of filled type; Center rope during outer layer strand symmetry bag is twisted with the fingers; In center rope comprise central strand 1 and internal layer thigh 2, central strand 1 periphery is evenly distributed with internal layer thigh 2, central strand 1, internal layer thigh 2 are 6 steel wire bags and twist with the fingers 1 steel wire system of twisting with the fingers and form; It is circular to restrict through extrusion process processing center, is extruded between central strand 1 and the internal layer thigh 2 to be face contact shape.Outer layer strand comprises central hair 5, internal layer silk 6, fills silk 3 and outer silk 4; Central hair 5 outsides are surrounded by internal layer silk 6, and internal layer silk 6 outsides are surrounded by outer silk 4, are filled with between internal layer silk 6 and the outer silk 4 and fill silk 3; Outer layer strand is handled through extrusion process; Central hair 5, internal layer silk 6, fill to be extruded between silk 3, the outer silk 4 and be face contact shape, outer layer strand is approximate trapezoid, outer layer strand and middle center rope close restrict circular.

Increased in the steel wire rope outer layer strand and to have filled silk, and the processing that is squeezed of outer layer strand and middle center rope, increased the compactedness of steel wire rope, the ABRASION RESISTANCE and the fatigue resistance of raising steel wire rope are specially adapted to lift jumbo.

The above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
