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.
The utility model content
In view of the problem that prior art exists, 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, by the internal layer rope strand of outer layer strands coating; With the center wire rope core that coats by the internal layer rope strand; The internal layer rope strand comprises first rope strand of the first quantity steel wire respectively by multiply and second rope strand that multiply comprises the second quantity steel wire respectively constitutes, and is face contact closely between first rope strand and second rope strand, contacts for face closely between outer layer strands and the internal layer rope strand.
In some embodiments of the utility model, outer layer strands is 8 strands, per sharely comprises the steel wire that 26 diameters differ.
In some embodiments of the utility model, first rope strand is 4 strands, per sharely comprises 7 steel wires, and second rope strand is 4 strands, per sharely comprises 19 steel wires that diameter is different.
In some embodiments of the utility model, the center wire rope core is 7 steel wires.
In some embodiments of the utility model, the outer layer strands cross section is fan-shaped.
According to the utility model, can increase the tensile strength of steel wire rope so that the rupture pull force of steel wire rope has improved more than 15% on the basis of general steel wire rope, prolonged the service life of steel wire rope.Simultaneously, steel wire rope is no longer loose, has reduced gravitation and friction between the internal layer rope strand, has increased the compactedness between each rope strand, makes steel wire rope tightr, wear-resisting, has improved the whole rope rupture pull force of steel wire rope

Fig. 6 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.
As depicted in figs. 1 and 2, a kind of steel wire rope comprises outer layer strands 1, 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.Internal layer rope strand 2 is made up of with multiply second rope strand 5 multiply first rope strand 4.Each thigh of first rope strand 4 comprises the first quantity steel wire.Each strand of second rope strand 5 comprises the steel wire of second quantity.
As shown in Figure 3, said outer layer strands 1 is 8 strands, per sharely is made up of 26 steel wires.
Like Fig. 4 and shown in Figure 5, said internal layer rope strand 2 is 8 strands, and wherein 4 strand of first rope strand 4 is per share comprises 7 steel wires, and 4 strand of second rope strand 5 be per share to comprise 19 steel wires.Because twisted technology makes 19 steel wire diameter differences that second rope strand 5 is per share.8 strands of internal layer rope strand 2 alternate twisteds form.During alternate twisted, thick thigh has guaranteed the hardness of rope strand, and thin thigh has guaranteed the toughness of rope strand.The center wire rope core is 7 steel wires.
The per share finer wire of outer layer strands 1, internal layer rope strand 2 and center wire rope core 3, forges through twisted after compacting through directly being twisted into face contact rope strand on the twisted machine again.
Fig. 6 schematically shows the longitudinal section that forges the mould that uses in the process according to the steel wire rope of the utility model.Mould is a strip shape, and the longitudinal section of 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; Cause wirerope diameter, reduced cross-sectional area; Silk in the rope is with burst distortion so that produce an opposed flattened and wear-resisting surface, the steel wire rope smooth surface, and breaking load increases.
Steel wire rope after forge, makes the steel wire distortion in the process of twisted.It is big that abutted surface between steel wire and the steel wire becomes, gap smaller.The outer layer strands cross section is fan-shaped, and the internal layer rope strand is by the alternate twisted with second rope strand of first rope strand.For face contact closely, increased the compactedness between each rope strand between each rope strand, made steel wire rope tightr, wear-resisting.Simultaneously, eliminate the gravitation between the internal layer rope strand, improved the rotatory of steel wire rope in the course of work, be difficult for distortion, improved the performance of steel wire rope, prolonged service life.
In the above-mentioned example of the utility model, steel wire rope forged behind twisted through 17 strand again form, comprise outer 8 strands, 8 strands of internal layers, and center wire rope core.The outer per share steel wire that 26 diameters differ that comprises.In internal layer 8 strand steel wire ropes 4 strands are per share to comprise 7 steel wires, in addition 4 strands of per share 19 diameters steel wires that differ that comprise.Forge through outer and internal layer, the rupture pull force of steel cable has been improved more than 15% on the basis of general steel cable.Rope strand is no longer loose, has increased the tensile strength of steel wire rope.Simultaneously, eliminate gravitation and friction between the internal layer rope strand, increased the compactedness between each rope strand, made steel cable tightr, wear-resisting, improved the rupture pull force and the life cycle of steel cable.This steel wire rope can be widely used in equipment such as excavator, tower lifting, and effect is obvious.
Be to be understood that; Though this specification is described according to embodiment; But be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, and those skilled in the art should make specification as a whole; Technical scheme among each embodiment also can form other embodiment that it will be appreciated by those skilled in the art that through appropriate combination.
The detailed description of preceding text only is specifying to the embodiment of the utility model; They are not the protection domain in order to restriction the utility model, allly do not break away from equivalent embodiment or the change that the utility model does and all should be included within the protection domain of the utility model.
