Abstract

The utility model discloses a filled-type compacted strand steel wire rope for hoisting, which comprises a central sub-rope and an outer layer, wherein the outer layer is surrounded by outer-layer strands; the central sub-rope is twisted and wrapped by the outer-layer strands; the central sub-rope comprises a central strand and inner-layer strands, wherein the inner-layer strands are uniformly distributed at the outer side of the central strand along the circumference; each outer-layer strand comprises a central yarn, inner-layer yarns, filling yarns and outer-layer yarns, wherein the central yarn, the inner-layer yarns, the filling yarns and the outer-layer yarns are in surface contact in sequence; the central strand and each inner-layer strand are respectively twisted through twisting and wrapping one steel wire by 6 steel wires; and the cross section of each outer-layer strand is shaped as a round honeycomb. According to the utility model, a structure that the central sub-rope is symmetrically twisted and wrapped by the outer-layer strands is adopted, the steel wires are densely combined, so that the wearing resistance, the durability and the anti-fatigue property of the steel wires are improved, therefore the service life of the steel wires is prolonged, and the hoisting safety is ensured. The filled-type compacted strand steel wire rope has the characteristics of simple structure, firmness and durability.

Description

Lift heavy is used the filled type compaction-strand 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 harbour or other heavy industry 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, and cost is high.Therefore the anti-fatigue performance of filled type 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, provides lift heavy a kind of simple in structure, durable to use the filled type compaction-strand steel wire rope.

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

Lift heavy is used the filled type compaction-strand steel wire rope; Center rope and outer in comprising, said skin is that outer layer strand surrounds, center rope during said outer layer strand symmetry bag is twisted with the fingers; The center rope comprises central strand and internal layer thigh in said; The said central strand outside is evenly distributed with the internal layer thigh along circumference, and said outer layer strand comprises central hair, internal layer silk, fills silk, outer silk, said central hair, internal layer silk, fills silk, outer silk and is face contact shape between successively.

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.

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

The design adopts center rope structure in the outer layer strand symmetry bag sth. made by twisting, and steel wire rope is closely knit, improves ABRASION RESISTANCE, durability and the fatigue resistance of steel wire rope, thereby improves the service life of steel wire rope.

Fig. 2 is the structural representation of the utility model outer layer strand;

Fig. 3 is the structural representation of center rope in the utility model.

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.

Like Fig. 1, Fig. 2, shown in Figure 3; Lift heavy is used the filled type compaction-strand steel wire rope; Center rope and outer in comprising; It is outer to be encircled into circle for outer layer strand 3, and outer layer strand 3 comprises central hair 4, internal layer silk 5, fills silk 6, outer silk 7, between adjacent central hair 4, the internal layer silk 5, fill between the silk 6, outer silk 7 is face between successively and contacts shape.Central hair 4 outsides are surrounded by internal layer silk 5, and central hair 4 cross sections are heptagon, and internal layer silk 5 cross sections are pentagon, and internal layer silk 5 outsides are surrounded by outer silk 7, are filled with between internal layer silk 5 and the outer silk 7 and fill silk 6, and filling silk 6 cross sections is triangle.Along circumference evenly distribute outer layer strand 3 symmetry bag twist with the fingers in the center rope; The center rope comprises central strand 1 and internal layer thigh 2 in said; Said central strand 1 outside is evenly distributed with six roots of sensation internal layer thigh 2 along circumference; Said 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, and the steel wire diameter of said central strand 1 is greater than the steel wire diameter of internal layer thigh 2.

Adopt center rope structure in the outer layer strand symmetry bag sth. made by twisting, steel wire rope is closely knit, improves ABRASION RESISTANCE, durability and the fatigue resistance of steel wire rope, thereby improves the service life of steel wire rope, guarantees lifting safety.Have characteristics simple in structure, durable.

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
