Abstract

The utility model discloses a filling type compaction steel wire rope for lifting. The filling type compaction steel wire rope comprises an outer layer formed by enclosure of outer-layer strands and a center sub-rope, wherein the outer-layer strands wrap and entwist the center sub-rope symmetrically, the center sub-rope comprises center stands and inner-layer strands which are uniformly distributed at the outer sides of the peripheries of the center strands, the outer-layer strands comprise center wires, inner-layer wires, filling wires and outer-layer wires, the inner-layer wires enclose the outer sides of the peripheries of the center wires, the outer-layer wires enclose the outer sides of the inner-layer wires, the filling wires are filled between the inner-layer wires and the outer-layer wires, and the outer-layer strands and the center sub-rope are combined to form a circle. The center strands and the inner-layer strands are both twisted by wrapping and twisting one steel wire by six steel wires, and the cross sections of the center wires and the filling wires are all circular. According to the utility model, the outer-layer strands with gaps filled with the filling wires are arranged at the outer side of the steel wire rope, the abrasion resistance and the fatigue resistance of the steel wire rope are enhanced, and the characteristics of long service life and simple structure are achieved.

Description

Lift heavy is with filled type compacting steel wire rope

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; Quickened the more New steps of China's harbour hoisting and hanging steel wire rope, any chemosphere is not plated on general at present employing galvanized steel wire rope or steel wire rope surface yet.The steel wire rope superficial layer of this structure has taken off easily, fracture, perishable getting rusty, so service life is short.The anti-fatigue performance of plastic-filled steel wire rope satisfies the demand that the harbour lifting is used 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 filled type compacting steel wire rope.

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

Lift heavy is with filled type compacting steel wire rope; Comprise skin that outer layer strand surrounds and middle center rope, center rope during said outer layer strand symmetry bag is twisted with the fingers, said in the center rope comprise 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, and said central hair periphery is surrounded by the internal layer silk, and the said internal layer silk outside is surrounded by outer silk; Be filled with between said internal layer silk and the outer silk and fill silk, said outer layer strand and middle center are restricted when closing rope to circular.

Further, said central strand, internal layer thigh are 6 steel wire bags and twist with the fingers 1 steel wire system of twisting with the fingers and form.

Further, said central hair is circle with a filling silk cross section.

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

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

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 filled type compacting steel wire rope, do not pass through the structure before the extrusion process.

The utility model is like Fig. 2, structure shown in Figure 3; Lift heavy comprises skin and middle center rope 1 that outer layer strand 2 surrounds with filled type compacting steel wire rope, center rope 1 during outer layer strand 2 symmetry bags are twisted with the fingers; Middle center rope 1 comprises central strand 3 and internal layer thigh 4; Central strand 3 periphery are evenly distributed with internal layer thigh 4, and central strand 3, internal layer thigh 4 are 1 steel wire of 6 steel wire bags sth. made by twisting system of twisting with the fingers and form, and middle center rope 1 is processed into circle through extrusion process.Outer layer strand 2 comprises central hair 5, internal layer silk 6, fills silk 7 and outer silk 8; Central hair 5 periphery are surrounded by internal layer silk 6; Internal layer silk 6 outsides are surrounded by outer silk 8, are filled with between internal layer silk 6 and the skin silk 8 and fill silk 7, and central hair 5 is circle with filling silk 7 cross sections.Outer layer strand 2 is circle when closing rope with middle center rope 1.

Have in the steel wire rope arranged outside and to insert the outer layer strand of filling silk in the slit, 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.

Claims

1. lift heavy is with filled type compacting steel wire rope; Comprise skin that outer layer strand surrounds and middle center rope, it is characterized in that: center rope during said outer layer strand symmetry bag is twisted with the fingers, said in the center rope comprise 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, and said central hair periphery is surrounded by the internal layer silk, and the said internal layer silk outside is surrounded by outer silk; Be filled with between said internal layer silk and the outer silk and fill silk, said outer layer strand and middle center are restricted when closing rope to circular.
