Abstract

The invention discloses a high-strength steel wire rope for lifting, which comprises a central portion, a first steel wire bundle layer, a second steel wire bundle layer and a third steel wire bundle layer, wherein the first steel wire bundle layer wraps the central portion, the second steel wire bundle layer wraps the first steel wire bundle layer, and the third steel wire bundle layer wraps the second steel wire bundle layer. The central portion comprises a fifth steel wire bundle, the first steel wire bundle layer comprises a group of fourth steel wire bundles in a mutually tangential manner, the second steel wire bundle layer comprises second steel wire bundles and third steel wire bundles which are alternately arranged and tangential to one another, and the third steel wire bundle layer comprises a group of first steel wire bundles in a mutually tangential manner. The high-strength steel wire rope for lifting adopts a point-line contact structure, so that the contact area of strands in the steel wire rope is larger, contact stress of steel wires inside the steel wire rope is reduced, the structural state of the steel wire rope can be effectively improved, use effect of the steel wire rope is enhanced, and the service life of the steel wire rope is prolonged.

Description

A kind of high strength promotes uses steel wire rope

Technical field

The present invention relates to a kind of steel wire rope, especially a kind of can all kinds of effectively hoisting machineries, boom hoist cable result of use and the high strength in life-span promotes and uses steel wire rope, belongs to the steel wire rope product technique field.

Background technology

Steel wire rope is the very large a kind of consumable material of use amount in engineering construction, the hoisting machinery; Main such steel wire rope of supporting use in various crane gears, lifting means; The serviceability of steel wire rope directly influences the efficient and the safety of construction; The high rupture pull force of ordinary steel rope is low, verticity is not poor, softness is bad, causes the service life of steel wire rope shorter, and the special-purpose lifting of development promotes with high strength and has very important significance with steel wire rope.

Summary of the invention

Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of can all kinds of effectively hoisting machineries, boom hoist cable result of use and the high strength in life-span promotes and uses steel wire rope.

The technical solution of the present invention is achieved: a high-strength steel wire rope for lifting, including the center portion, a first layer of wire bales, bales of the second wire layer, the third layer wire bales; said first layer of wire wrapped bales central portion; said second layer a first layer of wire wrapped bales; said third layer a second layer of steel wires wrapped bales bales; said central portion formed by the fifth wire bales; wherein the first layer wire bales a group of fourth wire bales tangent to each other to form; said second layer wire bales, bales of wire containing second and third wire bales; said second wire bales, the third wire bales and white settings, and another tangent; the said third layer of steel wire bales bales by a group of first tangent to each other to form; said first wire bales, the second wire bales, the third wire bales, the fourth wire bales, the fifth wire bales are seven steel wires .

Preferably, the diameter of the second wire than the third wire bales bales.

Because the utilization of technique scheme, the present invention compared with prior art has advantage:

The present invention is to enhance the use of a high-strength steel wire, the dot line contact structure, the steel cord of the larger contact area between the strands, reducing the contact stress the inner wire rope, the rope can effectively improve the structural condition, improve the rope use of effects and life; said each wire bales are seven steel wires, wire diameter relatively thin, high strength, high breaking force, does not rotate performance, flexibility and strong performance characteristics than normal hoisting rope has better Using performance.

Description of drawings

Below in conjunction with accompanying drawing technical scheme of the present invention is described further:

Fig. 1 is that high strength of the present invention promotes the sectional view with steel wire rope;

Where: 1, the first wire bales; 2, the second wire bales; 3, the third wire bales; 4, the fourth wire bales; 5, the fifth wire bales.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described.

As shown in Figure 1 of the present invention to enhance the use of a high-strength steel wire, including the center portion, a first layer of wire bales, bales of the second wire layer, the third layer wire bales; said first layer of wire wrapped bales Living central portion; said second layer a first layer of wire wrapped bales; said third layer a second layer of steel wires wrapped bales bales; said central portion 5 formed by the fifth wire bales; said first layer wire bales bales by a group of forty-four mutually tangent wire forming; said second layer wire bales, bales 2 contains a second wire, the third wire bales 3; said second wire bales 2, the third phase 3 wire bales set and tangent to each other; said third layer consists of a plurality of first wires wire bales bales 1 tangent to each other is formed; bales 1 of the first wire and the second wire bales 2, a third wire bales 3, the fourth wire bales 4, the fifth wire bales 5 by seven steel wires; said second wire is smaller than the diameter of the bales 2 3 third wire bales.

The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.

Claims

A method to enhance the use of high strength steel wire, characterized by: including the center portion, a first layer of wire bales, bales of the second wire layer, the third layer wire bales; said first layer of wire wrapped bales central portion; wherein The second layer is the first layer of wire wrapped bales; said third layer a second layer of steel wires wrapped bales bales; said central portion formed by the fifth wire bales; said first layer consists of a group of bales fourth wires Wire tangent to each other to form bales; said second layer wire bales, bales comprising a second wire, the third wire bales; bales of said second wire, the third wire bales white settings, and tangent to each other; said third layer wire bales bales by a group of the first wire is tangent to each other to form; said first wire bales, the second wire bales, the third wire bales, the fourth wire bales, the fifth wire bales are seven steel wires.
(2) as claimed in claim 1, wherein the rope, characterized in that: said second wire diameter than the third wire bales bales.
