Abstract

The utility model discloses a nine-strand filled steel wire rope for a high-rise high speed elevator, comprising a central strand, nine inner-layer strands and nine outer-layer strands. The nine inner-layer strands uniformly wrap and entwist the central strand, and the nine outer-layer strands uniformly wrap and entwist the inner-layer stands. The outer-layer strands are in a filled structure. Each inner-layer strand comprises a central steel wire and six steel wires uniformly wrapping and entwisting the central steel wire. A Warrington structure is adopted for the central strand. Compared with a Seale type nine-strand parallel entwisting elevator steel wire rope, the steel wire rope disclosed by the utility model has good reelability, and is suitable to be used as a thick-size steel wire rope for the high-rise high speed elevator.

Description

A kind of high-rise express elevator is with 9 strands of filled type steel wire ropes

Technical field

The utility model relates to a kind of steel wire rope, specifically, relates to a kind of high-rise express elevator with 9 strands of filled type steel wire ropes.

Background technology

Because the fast development of high-rise express elevator, terraced speed is more and more higher, and requirements of Wire Rope is also being improved.The high-rise express elevator parallel sth. made by twisting structure of 9*19S steel core, half steel independent wire strand core wire rope are when using thick specification wire rope (the above specification of 12mm), the steel wire rope reelability can be bad, cause that easily steel wire rope is wrapped in job-hopping phenomenon on the traction sheave, cause security incident, also steel wire rope is produced certain influence service life.

The utility model content

The purpose of this utility model is, at the problems referred to above, provide a kind of high-rise express elevator with 9 strands of filled type steel wire ropes, to realize that improving the steel wire rope reelability can improve, be fit to thick floor height speed elevator steel wire rope with a high standard, satisfy the demand of elevator for the reelability energy.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

High-rise express elevator comprises central strand, internal layer thigh and outer layer strand with 9 strands of filled type steel wire ropes, is characterized in, the number of share of stock of described internal layer thigh is 9 strands and even bag sth. made by twisting central strand, and the number of share of stock of described outer layer strand is 9 strands and evenly wraps and twist with the fingers the internal layer thigh; Described outer layer strand is the filled type structure, and the center is 1 core wire, and internal layer is evenly to wrap 10 finer wires twisting with the fingers core wire, and skin is evenly to wrap 10 thick wires twisting with the fingers internal layer, is provided with filler wires at the external void place of adjacent two steel wires of internal layer; Described internal layer thigh comprises 1 core wire and evenly wraps 6 steel wires twisting with the fingers core wire; Described central strand adopts a watt woods to gulp down the formula structure, and the center is 1 core wire, and internal layer is evenly to wrap 6 finer wires twisting with the fingers core wire, and skin is 6 thick wires and 6 finer wires of the even sth. made by twisting of bag at interval internal layer; Between described strand and the thigh, be line between steel wire and the steel wire and contact.The definition of thick wire and finer wire is that both compare, as long as the diameter of thick wire just can greatly than the diameter of finer wire.

The utlity model has following beneficial effect;

1, because high-rise express elevator adopts 9 bursts of parallel sth. made by twisting structures of filled type with 9 strands of filled type steel wire ropes, its bearing capacity, resistance rotatory power, diameter poker ability all can reach the requirement of 9 strands of Seal type ropes.

2, described 9 strands of filled type steel wire ropes are owing to per share steel wire number increases, and the cover wire number attenuates, and the relative 9 strands of Seal type ropes of its ABRASION RESISTANCE are low, but it can reach 16.5 around line of coefficients, contrast 9 strands of Seal type ropes and improve above 10%.

3, described 9 strands of filled type steel wire ropes are when steel wire rope specification relatively thick (more than the 12mm specification), and the steel wire rope reelability requires when higher, and result of use is better than 9 strands of Seal type ropes.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, high-rise express elevator comprises central strand 3, internal layer thigh 2 and outer layer strand 1 with 9 strands of filled type steel wire ropes, and the number of share of stock of internal layer thigh 2 is 9 strands and even bag sth. made by twisting central strand 3, and the number of share of stock of outer layer strand 1 is 9 strands and evenly wraps and twist with the fingers internal layer thigh 2.

As shown in Figure 2, outer layer strand 1 is the filled type structure, and the center is 1 core wire, and internal layer is evenly to wrap 10 finer wires twisting with the fingers core wire, skin is evenly to wrap 10 thick wires twisting with the fingers internal layer, is provided with filler wires at the external void place of adjacent two steel wires of internal layer.

As shown in Figure 3, internal layer thigh 1 comprises 1 core wire and evenly wraps 6 steel wires twisting with the fingers core wire.

As shown in Figure 4, central strand 3 adopts a watt woods to gulp down the formula structure, and the center is 1 core wire, and internal layer is evenly to wrap 6 finer wires twisting with the fingers core wire, and skin is 6 thick wires and 6 finer wires of the even sth. made by twisting of bag at interval internal layer; It is a finer wire that described interval bag is twisted as between two thick wires, is a thick wire between two finer wires.

Between described strand and the thigh, be line between steel wire and the steel wire and contact.

It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail 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 spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
