Description
Technical field
The present invention relates to a kind of hawser, more particularly to a kind of hawser of deep sea petroleum exploration.
Background technology
Existing deep sea cable is made of wire rope core and wrap, wherein, wire rope core be by multiply cordage twisting or braiding and
Into wrap is the tube-in-tube structure formed by the braiding of multiply cordage, and wrap is set on wire rope core and wraps wire rope core.
Hole is woven during use, on the coated set of grit in seabed and seawater to enter between wrap and wire rope core, or even into
Enter to inside wire rope core.In this way, when using the deep sea cable, into deep sea cable grit respectively with forming wire rope core and wrap
Cordage phase mutual friction, the cordage for causing to form wire rope core and wrap is worn or even rubs, and then causes wire rope core and bag
Sheathing is damaged, substantially reduces the service life of deep-sea cable.
In the prior art, the patent of Application No. CN201611041861.X discloses a kind of high-strength corrosion-resisting deep-sea cable
Rope, including rope body, external coating and wire rope core, the rope body inside center are equipped with wire rope core, the wire rope core by some rope strand coil bucklings and
Into the wire rope core outside is coated with waterproof oxidation prevention layer, and core fiber layer, the core fiber layer are coated with the outside of the waterproof oxidation prevention layer
Formed for high-strength high-modulus fibre material twisted, external coating is coated with the outside of the core fiber layer, the external coating is in brocade
Synthetic fibre multifilament fiber material, the external coating surface are equipped with coating, and the coating is anti-particulate layer.The technical solution solves biography
The problem of system hawser is caused hawser intensity decreases, is caused security risk using middle abrasion.But the technical solution still have with
Lower shortcoming：The 1st, waterproof oxidation prevention layer is set outside wire rope core, the sandwich construction such as core fiber layer and external coating, increases deep-sea
Hawser causes inconvenient for use in the weight of use state itself.2nd, waterproof oxidation prevention layer, core fiber layer and external coating and sandwich layer bag
Process is covered to consider its corrosion resistance and abrasion resistance properties, manufactures processed complex.
The content of the invention
In view of the above deficiencies of the prior art, it is an object of the invention to provide a kind of cable of deep sea petroleum exploration
Rope, to realize the weight for mitigating deep sea cable in use state itself, and has good corrosion resistance and abrasion resistance properties.
The present invention specifically uses following technical scheme to achieve these goals：
A kind of hawser of deep sea petroleum exploration, including wire rope core and clad, the wire rope core are formed by multiply rope strand coil buckling,
