Abstract

The utility model discloses a locked coil wire rope which comprises an anticorrosive coating, center wires arranged in the anticorrosive coating and at least an outer wire layer that is twisted on the perimeter of the center wires and composed of a plurality of outer wires. The utility model is characterized in that: anticorrosive filling materials are filled in the space between the center wires and the outer wires, between adjacent outer wire layers and between the adjacent outer wire layers that are adjacent to the outer wire layer; the anticorrosive filling materials and the anticorrosive coating are melted and fixed on the center wires and the outer wires. The utility model has the advantages that: not only the anticorrosive coating is coated on the external surface of the wire rope, the anticorrosive filling materials are also filled in the space between the center wires and the outer wires, between the adjacent outer wire layers and between the adjacent outer wire layers that form the outer wire layer, and the anticorrosive filling materials and the anticorrosive coating are melted and fixed on the center wires and the outer wires, thus greatly improving the locked performance of the wire rope and realizing higher corrosion prevention performance, and effectively improving the service life and safety performance of the wire rope.

Description

A kind of locked coil wire rope

Technical field

The utility model relates to a kind of steel wire rope, especially relates to a kind of locked coil wire rope.

Background technology

Existing steel wire rope product is compared and is widely used for being used to make motorcycle, automobile brake line, lifting, lifting pull rope and braided metal steel wire etc.It mainly comprises central hair and stranded in the outer silk of central hair periphery, common multilayer steel wire rope is only at superficies coating plastic layer, but because of there being big gap between its silk and the silk, cause its sealing relatively poor, Corrosion Protection is not high, anti-fatigue performance a little less than, service life of whole steel wire rope product is short, security performance is lower.The patent No. is that 200520074385.2 Chinese utility model patent discloses a kind of multilayer coated cable, it comprises central hair or central strand (1) and stranded in central hair or peripheral outer silk or the outer layer strand (3) of central strand (1), and characteristics are that described central hair or central strand (1) outer surface are coated with plastic layer (2); Described outer silk or outer layer strand (3) outer surface are coated with plastic layer (4).This utility model adopts the multilayer clad structure, can make between silk and strand, strand and the thigh to reduce friction, and anticorrosive property and fatigue behaviour are preferably arranged, and can improve service life and security reliability.But in the use of reality, it is found that, this constructed products is when concrete the use, owing to the clad at two must be removed, therefore in use for some time, the part of not only removing clad can be got rusty, and inner steel wire also can get rusty, and this defective that exists on Corrosion Protection directly has influence on the service life and the security performance of steel wire rope product.

Summary of the invention

Technical problem to be solved in the utility model provides and a kind ofly can improve Corrosion Protection better, thereby improves the locked coil wire rope of service life and security performance effectively.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of locked coil wire rope, comprise anticorrosive coat and be arranged on the central hair in the described anticorrosive coat and one deck is stranded in the outer silk layer that is made of many outer silks of described central hair periphery at least, between described central hair and the described outer silk layer, be filled with anticorrosive packing between the adjacent outer silk layer and in the gap between the adjacent outer silk of described outer silk layer, described anticorrosive packing and described anticorrosive coat fusion are fixed on described central hair and the described outer silk.

Described anticorrosive coat and described anticorrosive packing can be identical materials, also can be different materials.

Described anticorrosive coat can be among PVC, PE, PP, PA and the TPU a kind of, what described anticorrosive packing also can be among PVC, PE, PP, PA and the TPU is a kind of.

Compared with prior art, advantage of the present utility model is not only to coat anticorrosive coat at the outer surface of steel wire rope, and between central hair and the outer silk layer, between the adjacent outer silk layer and the gap that constitutes between the adjacent outer silk of outer silk layer filled with anticorrosive packing, and anticorrosive packing and anticorrosive coat fusion be fixed on central hair and the outer silk, improved the sealing property of steel wire rope greatly.Below be one group of experimental data:

1. sealing experiment: experimental condition is: earlier steel wire rope is applied certain pretension, make the sample of growing into 300mm again, vacuum is 0.5 ± 0.05MP, and the time is 30 minutes.The sample of two kinds of steel wire ropes respectively is 300.Result's none part of steel wire rope product of the present utility model is undesirable, the steel rope of other structures then have many undesirable.

2. environmental corrosion test: experimental condition is: all remove the two ends epidermis of two kinds of steel wire ropes about 20mm, be put in the environmental test chamber again, after 80 circulations, steel wire rope of the present utility model only has the steel wire corrosion of exposed part, and the steel wire rope of other structure not exposed part corrosion has also appearred.

Can find out significantly from above-mentioned experimental data, locked coil wire rope of the present utility model is more reliable and more stable than the sealing property of the steel wire rope of other structures of prior art, Corrosion Protection is higher, thereby can improve the service life and the security performance of steel wire rope effectively.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment one: as shown in Figure 1, a kind of locked coil wire rope, comprise anticorrosive coat 1 and be arranged on central hair 2 in the anticorrosive coat 1 and one deck stranded in the outer silk layer 4 that constitutes by many outer silks 3 of central hair 2 peripheries, anticorrosive coat 1 is made by PE, be filled with anticorrosive packing 5 in the gap between central hair 2 and the outer silk layer 4, between the adjacent outer silk 3 of outer silk layer 4, anticorrosive packing 5 is PE, and anticorrosive packing 5 and anticorrosive coat 1 fusion are fixed on central hair 2 and the outer silk 3.

Embodiment two: as shown in Figure 2, a kind of locked coil wire rope, comprise anticorrosive coat 1 and be arranged on central hair 2 in the anticorrosive coat 1 and two layers stranded in the outer silk layer 4 that constitutes by many outer silks 3 of central hair 2 peripheries, anticorrosive coat 1 is made by PP, be filled with anticorrosive packing 5 in the gap between central hair 2 and the outer silk layer 4, between the adjacent outer silk 3 of outer silk layer 4, anticorrosive packing 5 is PP, and anticorrosive packing 5 and anticorrosive coat 1 fusion are fixed on central hair 2 and the outer silk 3.

In the above embodiments, anticorrosive coat 1 also can be different materials with anticorrosive packing 5, and anticorrosive coat 1 also can be made by PVC, PA or TPU, and anticorrosive packing 5 also can be PVC, PA or TPU.

Product of the present utility model can adopt following method to make: coat central hair outside behind the certain thickness anticorrosive packing and will outer layer to be stranded in outside the anticorrosive packing, by that analogy, up to outside outermost, coating anticorrosive coat outside the silk layer, and then it is warmed to the temperature of setting, utilize special fixture with certain corresponding time of pressure clamping again, anticorrosive packing and anticorrosive coat are infiltrated be filled between central hair and the outer silk layer, in the gap between the adjacent outer silk of outer silk layer, and fusion is fixed on central hair and outer.
