Description

A kind of 12 strands, four directions is anti-turns round steel wire rope

Technical field

The utility model relates to a kind of steel wire rope, and more particularly, it relates to, and a kind of 12 strands, four directions is anti-turns round steel wire rope.

Background technology

Knitting twisting-proof steel cable, also claims wire rope without twisting or non-rotating cable.It manufactures is that braiding with the zinc-plated round-strand rope of sub-thread of one group of left-hand lay and one group of dextrad sth. made by twisting is regular (helical trajectory of intersection) forms, wherein left-hand lay stock and dextrad twist with the fingers that number of share of stock amount is equal, asymmetrical braid, be widely used in power department transmission and transformation engineering construction tension stringing, traction and guiding is restricted or for other industrial circles as operations such as lifting, transport, rigging, horizontally tractings.

12 strands, four directions common on market prevents that turning round construction of wire rope is the structures such as 12*25Fi, 12*29Fi, 12*19W, 12*19S.There is shortcoming:

1, because center is hollow, operationally rub mutually between steel wire, wearing and tearing are comparatively serious, and steel wire gets rusty easily, and anticorrosive property is poor, and service life is short;

2, such as 12*25Fi, 12*29Fi filled type structure, fill silk in the gap that two-layer steel wire is formed, filler wires diameter is superfine, and time stressed, easy fracture of wire sticks up from steel wire seam, forms burr, not only affect pulling force on steel wire rope surface, and also impact operation uses;

3, the structure of such as 12*19S Xi Lushi, ectonexine quantity is identical, and cover wire diameter is comparatively thick, and steel wire of internal layer diameter is comparatively thin, and ABRASION RESISTANCE is good, but flexibility is poor;

4, such as 12*19W watt of woods gulps down the structure of formula, and cover wire quantity is the twice of steel wire of internal layer number, and flexibility is comparatively strong, but ABRASION RESISTANCE is poor.

Application number be 91212767.8 square 12 strands of special torsionproof steel wire ropes description disclose steel cord structure be 12*19W exist ABRASION RESISTANCE poor and between steel wire easily mutually friction there is the defects such as fracture, service life is short.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of cubic 12 strands to prevent turning round the good ABRASION RESISTANCE of steel wire rope and flexibility, and anticorrosive property is strong, and wear and rupture is less likely to occur steel wire, long service life.

For achieving the above object, the utility model provides following technical scheme: a kind of 12 strands, four directions is anti-turns round steel wire rope, comprise 12 strand stocks, in described 12 strand stocks, six strand stock left-hand lays and six strands of right-handed twists compile sth. made by twisting alternately, form tetragonal cross section, wherein steel wire rope center is fibre core, described rope strand comprises core wire from the inside to the outside successively, internal layer stock, secondary outer layer strand and outer layer strand, internal layer stock is made up of 5 steel wire of internal layer, by 5, cover wire and 5 second time cover wires are formed secondary outer layer strand for the first time, cover wire is spaced with second time cover wire for the first time, outer layer strand is made up of 10 cover wires, the structure of per share rope strand is 1+5+5/5+10 and 1*26WS.

As preferably, described rope strand, cover wire, first time cover wire, second time cover wire, steel wire of internal layer and core wire diameter ratio be 4.35:1:0.67:0.53:0.56:0.41.

As preferably, described cover wire, first time cover wire, second time cover wire, steel wire of internal layer and core wire surface be all coated with zinc layers.

Compared with prior art, the utility model has the advantage of: first 12 strands, four directions is compared cubic stereotyped writing and increased on pulling force, and steel wire rope comprises a fibre core at center, fibre core is due to through oil-feed process, during use, grease oozes out lubrication on steel wire rope surface by the extruding of each rope strand, prevent steel wire wear generation fracture of wire phenomenon, secondly the existing good ABRASION RESISTANCE of hybrid arrangement of rope strand 1*26 has again good flexibility, both the service life of steel wire rope had been improved, turn avoid steel wire rope and beat the working strength tussled around reducing operative employee, a special diameter proportion ensure that the intensity of steel wire rope, and improve corrosion resistance further in the zinc-plated process of Steel Wire Surface.
