Abstract

The utility model discloses a steel wire rope with compacted strands for hoisting, which comprises a central auxiliary rope and outer-layer strands. The central auxiliary rope is arranged in a space defined by the outer-layer strands. The outer-layer strands are wrapped and entwisted outside the central auxiliary rope symmetrically. The central auxiliary rope comprises a central strand and an inner-layer strand. Each outer-layer strand comprises a central wire, an inner-layer wire, a secondary outer-layer thin wire, a secondary outer-layer thick wire and an outer-layer wire. The central wire, the inner-layer wire, the secondary outer-layer thin wire, the secondary outer-layer thick wire and the outer-layer wire are sequentially contacted in surface mode. The central strand and the inner-layer strand are both formed by entwisting of 6 steel wires which are wrapped and entwisted outside 1 steel wire symmetrically. The steel wire rope with the compacted strands adopts a structure that the outer-layer strands are wrapped and entwisted outside the central auxiliary rope symmetrically, is compact in the steel wire rope, improves abrasion-resisting performance, durability and fatigue resistance of the steel wire rope, prolongs service life of the steel wire rope, and guarantees safety of hoisting. The steel wire rope with the compacted strands has the advantages of being simple in structure, strong and durable.

Description

Lift heavy is used compaction-strand steel wire rope

Technical field

The utility model relates to a kind of lifting, handling apparatus, 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 hoisting appliance 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 bearing capacity, ABRASION RESISTANCE and the resistance to shock loads ability of steel wire rope.

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 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 compaction-strand steel wire rope; Center rope and outer layer strand in comprising; Said outer layer strand surrounds has middle center to restrict in the space, center rope during said outer layer strand symmetry bag is twisted with the fingers, and said middle center rope comprises central strand and internal layer thigh; Said outer layer strand comprises central hair, internal layer silk, inferior outer filaments, inferior outer crin, outer silk, and central hair, internal layer silk, inferior outer filaments, inferior outer crin, outer silk are face contact shape between successively.

Further, said central strand, internal layer thigh are 6 steel wires symmetry bag 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 bearing capacity, 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 compaction-strand steel wire rope; Center rope and outer layer strand 3 in comprising; Outer layer strand 3 surrounds has middle center rope in the space, outer layer strand 3 comprises central hair 4, internal layer silk 5, inferior skin, outer silk 8, is surface contact state between adjacent successively central hair 4, internal layer silk 5, inferior skin, the outer silk 8.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 hexagon; Internal layer silk 5 outsides are surrounded by time skin, and inferior skin is that time outer crin 6 constitutes with time outer filaments 7 interlaced intervals, and the inferior skin outside is surrounded by outer silk 8.Along circumference evenly distribute outer layer strand 3 symmetry bag twist with the fingers in the center rope; Middle center rope comprises central strand 1 and internal layer thigh 2; Central strand 1 outside is evenly distributed with six roots of sensation internal layer thigh 2 along circumference; Central strand 1, internal layer thigh 2 are 1 steel wire of 6 steel wire symmetry bag sth. made by twisting system of twisting with the fingers and form, and the steel wire diameter of 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
