As a kind of preferred embodiment of the utility model, the outer layer strand is by 9 first outer layer thicker wires, 9 pieces first Layer finer wire, 1 first core wire twisting form；It is designed by using such structure, wear-resisting property can be effectively improved, prolonged The service life of long wirerope.

As a kind of preferred embodiment of the utility model, the internal layer stock is by 1 second core wire and 6 second outer layers Steel wire is constituted, and 6 second cover wire packets are twisted in the outside of second core wire, second core wire Diameter is identical as the diameter of the second cover wire.

As a kind of preferred embodiment of the utility model, the fiber wire rope core is by several polyurethane fiber silks and 2 carbon Fiber rope strand is twisted to be formed.

As a kind of preferred embodiment of the utility model, the outer layer strand is 9 strands, and the internal layer stock is 9 strands.

As a kind of preferred embodiment of the utility model, the resinous coat with a thickness of 0.5mm~1.5mm.

As a kind of preferred embodiment of the utility model, the resinous coat with a thickness of 1mm.

The beneficial effects of the utility model are that the utility model uses fiber wire rope core, can effectively improve oil storage performance, and The frictional force between internal layer stock and wire rope core can be reduced, is effectively prolonged the service life, and fiber wire rope core is by several polyurethane fibers Silk and multiple carbon fiber rope strands, which are twisted together, to be formed, and has the characteristics that intensity is high, elasticity is good, secondly, being provided with resin outside internal layer stock Coating can reduce the frictional force between internal layer stock and outer layer strand, and then prolong the service life, in addition, outer layer strand is compacting stock, Steel wire in outer layer strand is in surface contact state, and then can greatly improve wear-resisting property, is effectively prolonged the service life.
