Abstract

The utility model provides an elevator steel wire rope with good balance and reelability, comprising a central strand, inner-layer strands, and outer-layer strands. The inner-layer strands are twisted and wrapped around the central strand symmetrically; and the outer-layer strands are disposed on the outermost side of the steel wire rope through wrapping and twisting symmetrically. The elevator steel wire rope is simple, reasonable and compact in structure. The elevator steel rope is formed through twisting of eight outer-layer strands and a central sub-rope, with the eight outer-layer strands twisted and wrapped around the central sub-rope, and each outer-layer strand is formed through twisting of six inner-layer thick steel wires and six outer-layer thick steel wires and twisting of six thin steel wires and a central steel wire according to a Warrington type. With the above-mentioned structure, the steel wire rope has relatively high anti-fatigue bending properties, has improved reelability, and thus has improved bearing capacity. The elevator steel wire rope is characterized by commendable balance, reelability, and bearing capacity, so the elongation of the steel wire rope is reduced.

Description

The all good elevator wire ropes of balance reelability

Technical field

The utility model relates to a kind of steel wire rope and preparation method thereof, specifically is meant all good elevator wire ropes of balance reelability.

Background technology

Along with the elevator industry competition is growing more intense, elevator stresses more and more that with rope high reelability is with high-mechanic property.At present, elevator is in the majority with 8*19S+NF structure class steel wire rope with steel wire rope, and the reelability of this type steel wire rope is bad, and balance and bearing capacity are relatively poor.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of reelability to use steel wire rope with all good elevators of balance.

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

The all good elevator wire ropes of balance reelability, its structure comprises central strand, internal layer thigh and outer layer strand, and said internal layer thigh wraps the sth. made by twisting central strand symmetrically, and said outer layer strand is wrapped sth. made by twisting symmetrically in the steel wire rope outermost.

Further be improved to, said steel wire rope is that the center rope system of twisting with the fingers forms in being twisted with the fingers by 8 outer layer strand bags, and each outer layer 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.

Moreover said middle center rope is to twist with the fingers the central strand system of twisting with the fingers by 8 internal layer thigh bags to form, and its each internal layer thigh 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 8 outer layer strand bags; Each outer layer 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; Middle center rope is to twist with the fingers the central strand system of twisting with the fingers by 8 internal layer thigh bags to form, and its each internal layer thigh is to wrap the sth. made by twisting core wire symmetrically by 6 steel wires.The steel wire rope of this structure has higher antifatigue bending property, has improved the reelability of steel wire rope greatly, and then has improved the bearing capacity of steel wire rope.Contrast the 8*19S+NF steel wire rope that present conventional lift uses, this structure breaking force of rope 0.356 has improved 21.5%, can improve 20% around coefficient 18.5, and diameter range requires+2%～+ 4%, has dwindled one percentage point.

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, all good elevator wire ropes of balance reelability comprise outer layer strand 1, internal layer thigh 2 and central strand 3, and internal layer thigh 2 wraps symmetrically twists with the fingers central strand 3, and outer layer strand 1 is wrapped symmetrically and twisted with the fingers in the steel wire rope outermost.

Central strand 3 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 wrap the sth. made by twisting core wire symmetrically by 6 steel wires.

Outer layer 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.

Its preparation method is:

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.Being prepared into Wa Lin gulps down formula outer layer strand 1, internal layer thigh 2 and Wa Lin and gulps down formula central strand 3.

When closing rope, twist with the fingers central strand 3 (or hemp core 4) by 8 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 8 outer layer strand, 1 bag spill rope 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.

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.
