Description

Steel wire rope

Technical field

The utility model relates to building and engineering material, particularly steel wire rope.

Background technology

Steel wire rope is the very large a kind of consumable material of use amount in producing, living.Directly influence the efficient and the safety of production, life the service life of steel wire rope.The steel wire rope that common process is twisted with the fingers system shows not wear-resisting performance under conditions such as vertical shaft hoisting, in the use therefore the phenomenon of fracture of wire in advance can be arranged more, and fracture of wire quantity transfinites and then need scrap.

Also there is structural unstable defective in the conventional structure steel wire rope.Rope strand is circular, and tangent to each other between the rope strand, the space between the rope strand is bigger, has gravitation and friction inevitably between the steel wire of internal layer rope, has reduced the compactedness between each strand, has influenced the life-span of steel wire rope greatly.

The conventional structure steel wire rope also can be because of the density metal coefficient be low, and breaking force of rope is little, has a strong impact on its use.Therefore, have to strengthen the diameter of steel wire rope, or improve the tensile strength of steel wire rope.Parallel sth. made by twisting forge wire rope of the prior art, steel cable is loose, and whole rope rupture pull force is not enough.Twist-on-twist of the prior art adds the diffusing head and the wick that produce when independent wire strand is produced and all can not solve simultaneously, and rupture pull force usually can't produce a desired effect.

The utility model content

The purpose of the utility model is to provide a kind of novel steel wire rope.

To achieve these goals, the utility model provides a kind of steel wire rope, comprising:

Outer layer strands contacts for face closely between internal layer rope strand that is coated by outer layer strands and the center wire rope core that is coated by the internal layer rope strand, outer layer strands and internal layer rope strand.

In some embodiments, outer layer strands is 6 strands, per sharely is made up of 19-103 root steel wire.

In some embodiments, the internal layer rope strand is 6 strands, per sharely comprises 7 steel wires.

In some embodiments, the center wire rope core is a nylon rope.

In some embodiments, the outer layer strands cross section is fan-shaped.

According to the utility model; The rupture pull force of steel wire rope has been improved more than 10% on the basis of general steel wire rope, increased the tensile strength of steel wire rope, prolong the service life of steel wire rope; Gravitation and friction between the internal layer rope strand have been eliminated simultaneously; Increase the compactedness between each rope strand, make steel wire rope tightr, wear-resisting, eliminated such steel wire rope have no idea for a long time problem of solving of head and lantern of loosing.

Fig. 2 is the section structure sketch map of the steel wire rope of a kind of embodiment of the utility model;

Fig. 3 be the utility model one embodiment steel wire rope forge the mould sketch map.

The specific embodiment

Come the utility model is done further to describe in detail explanation below in conjunction with accompanying drawing and specific embodiment.

Embodiment one

As shown in Figure 1, steel wire rope comprises: outer layer strands 1, and by the internal layer rope strand 2 of outer layer strands 1 coating and the center wire rope core 3 that coats by internal layer rope strand 2.

Outer layer strands 1 is 6 strands, and the per share steel wire that is differed by 19 diameters is formed, and in the present embodiment, outer layer strands 1 per share interior steel wire radical all is 19.

Internal layer rope strand 2 is 6 strands, and the per share steel wire that is differed by 7 diameters is formed.Center wire rope core 3 is a nylon rope.

Outer layer strands 1, internal layer rope strand 2 and center wire rope core 3 are through after the compacting, and first twisted forges and forms.Per share finer wire is through directly being twisted into face contact rope strand on the twisted machine.

Fig. 3 has schematically shown the longitudinal section that forges mould in the process according to the steel wire rope of the utility model.Mould is a strip shape, and the longitudinal section of its lower ending opening is semicircle.When forging, in mould openings, put into pad, will wait that again the steel wire rope of beating puts into mould openings; The X common swager of series (X30 type and X50 type) that uses Chuangxin Precision Instrument Inst., Xian to produce forges steel wire rope; Make wirerope diameter, reduced cross-sectional area, a silk in the rope and a burst distortion, so that produce an opposed flattened and wear-resisting surface; The steel wire rope smooth surface, breaking load increases.

Embodiment two

As shown in Figure 1, steel wire rope comprises outer layer strands 1, internal layer rope strand 2 and center wire rope core 3, and wire rope core 3 outsides in center are covered with internal layer rope strand 2, and internal layer rope strand 2 outsides are covered with outer layer strands 1.

Outer layer strands 1 is 6 strands, and the per share steel wire that is differed by 103 diameters is formed.In the present embodiment, outer layer strands 1 per share steel wire radical all is 103.

Internal layer rope strand 2 is 6 strands, and the per share steel wire rope that is differed by 7 diameters is formed.Center wire rope core 3 is a nylon rope.

Outer layer strands 1, internal layer rope strand 2 and center wire rope core 3, per share finer wire forges through twisted after the compacting through directly being twisted into face contact rope strand on the twisted machine, forms steel wire rope.

The process that forges is used mould shown in Figure 3, and process is identical with process among the embodiment one, no longer explanation here.

Embodiment three

Outer layer strands 1 is 6 strands, per sharely is made up of 61 diameters steel wire that differs, and in the embodiment of the utility model, the steel wire radical in outer layer strands 1 is per share all is 61.
