Abstract

The utility model relates to a compacted strand steel wire rope for an elevator, which structurally comprises a central strand, an inner-layer strand and outer-layer strands, wherein the central strand is wrapped and entwisted by the inner-layer strand and the outer-layer strands are wrapped and entwisted on the outmost side of the steel wire rope. The compacted strand steel wire rope for the elevator is simple, reasonable and compact in structure. The steel wire rope is formed by entwisting nine outer-layer strands on a central sub-rope, each of the outer-layer strands is formed by extruding in a seal form and wrapping and entwisting nine outer-layer rough wires and nine inner-layer thin wires on one central wire, and the steel wires in the outer-layer strands are under surface contact state. The steel wire rope with such a structure has higher wear-resisting property and the bearing capacity of the steel wire rope is increased. The wear-resisting property and the bearing capacity of the steel wire rope for the elevator are excellent and the breaking force of the steel wire rope is increased.

Description

A kind of compaction-strand steel wire rope for elevator

Technical field

The utility model relates to a kind of steel wire rope and preparation method thereof, specifically is meant a kind of compaction-strand steel wire rope for elevator.

Background technology

Along with the elevator industry competition is growing more intense, elevator is more and more stressed high-wearing feature and high-mechanic property with rope.At present, elevator is in the majority with 9*19S circle strand structure class steel wire rope with steel wire rope, and the ABRASION RESISTANCE of this type steel wire rope is bad also relatively poor with bearing capacity.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of ABRASION RESISTANCE and all good elevators of bearing capacity to use steel wire rope.

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

A kind of compaction-strand steel wire rope for elevator, its structure comprises central strand, internal layer thigh and outer layer strand, and said internal layer thigh bag is twisted with the fingers central strand, and said outer layer strand bag is twisted with the fingers in the steel wire rope outermost.Said steel wire rope is to be formed by the center rope system of twisting with the fingers in 9 outer layer strand bags sth. made by twisting, and each outer layer strand is to be Xi Lushi and to be formed through extrusion production by outer 9 thick wires, 1 central hair of 9 finer wire bags sth. made by twisting of internal layer, and steel wire is surface contact state in the outer layer strand.

Moreover said middle center rope is to twist with the fingers the central strand system of twisting with the fingers by 9 sub-thread bags to form, and its each sub-thread is to wrap the sth. made by twisting core wire system of twisting with the fingers symmetrically by 6 steel wires to form.

Moreover said central strand is to twist with the fingers a core wire by 6 thick wires of internal layer and outer 6 thick wires, 6 finer wire bags to be Wa Lin and to gulp down the formula system of twisting with the fingers and form.

The beneficial effect of the utility model is following:

Because said steel wire rope is that the center rope system of twisting with the fingers forms in being twisted with the fingers by 9 outer layer strand bags, each outer layer strand is by being to twist with the fingers 1 central hair by outer 9 thick wires, 9 finer wire bags of internal layer to be Xi Lushi and to form through extrusion production, and steel wire is surface contact state in the outer layer strand.Middle center rope is to twist with the fingers the central strand system of twisting with the fingers by 9 sub-thread bags to form, and its each sub-thread is to wrap the sth. made by twisting core wire symmetrically by 6 steel wires.The steel wire rope of this structure has higher anti-wear performance, and has improved the bearing capacity of steel wire rope.Contrast the 9*19S round-strand rope that present conventional lift uses, this structure breaking force of rope 0.42 has improved 7.69%, and ABRASION RESISTANCE contrast 9*19S round-strand rope improves 20%.

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

As shown in Figure 1, a kind of compaction-strand steel wire rope for elevator comprises central strand 1, internal layer thigh 2 and outer layer strand 3, and internal layer thigh 2 bags are twisted with the fingers central strand 1, and outer layer strand 3 bags are twisted with the fingers in the steel wire rope outermost.

Central strand 1 is to twist with the fingers a core wire by 6 thick wires of internal layer and outer 6 thick wires, 6 finer wire bags to be Wa Lin and to gulp down the formula system of twisting with the fingers and form.

Internal layer thigh 2 is to twist with the fingers core wire by 6 steel wire bags.

Outer layer strand 1 is to be Xi Lushi and to be formed through extrusion production by outer 9 thick wires, 1 central hair of 9 finer wire bags sth. made by twisting of internal layer, and steel wire is surface contact state in the outer layer strand.

Its preparation method is:

The mode of production of utilizing die drawing is carried out (cold-)drawn (steel)wire rope rope strand with mould when twisting with the fingers burst, wire shape in changing strand but do not change the cross-sectional area of steel wire basically makes to be face between steel wire and steel wire in the rope strand and to contact shape, is prepared into Xi Lushi outer layer strand 3.

Arranged steel wire through noseplate twisting with the fingers on strand car, produced desired structure, effectively eliminated the stress of thigh again through post-former, be received on the I-beam wheel then through closing up mouthful to compress with the line ball punching block.Be prepared into the internal layer thigh and a watt woods gulps down the formula central strand.

When closing rope, twist with the fingers central strand 1 by 9 internal layer thighs, 2 bags earlier and on finished car, arrange, through pre-former through noseplate; Compress through closing up mouth again, effectively eliminate the stress of thigh again through post-former, be received in then and form sub the rope on the I-beam wheel; Arrange through noseplate on finished car by 9 outer layer strand, 3 bag spill ropes again,, compress through closing up mouth again through pre-former; Effectively eliminate the stress of thigh again through post-former, be received in then and form steel wire rope on the I-beam wheel.

Because said steel wire rope is to be formed by the center rope system of twisting with the fingers in 9 outer layer strand bags sth. made by twisting, each outer layer strand is to be Xi Lushi and to be formed through extrusion production by outer 9 thick wires, 1 central hair of 9 finer wire bags sth. made by twisting of internal layer, and steel wire is surface contact state in the outer layer strand.Middle center rope is to twist with the fingers the central strand system of twisting with the fingers by 9 sub-thread bags to form, and its each sub-thread is to wrap the sth. made by twisting core wire symmetrically by 6 steel wires.The steel wire rope of this structure has higher anti-wear performance, and has improved the bearing capacity of steel wire rope.Contrast the 9*19S round-strand rope that present conventional lift uses, this structure breaking force of rope 0.42 has improved 7.69%, and ABRASION RESISTANCE contrast 9*19S round-strand rope improves 20%.

What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.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.
