In particular, the fiber core strand 2 is twisted from a plurality of fiber filaments, which are impregnated with grease. The fiber filaments can play a good role in supporting, damping and oil storage at the center of the steel wire rope so as to be matched with the outer tubular core body to ensure the reliable structural property.
Preferably, the fiber filaments are any one or more of terylene, carbon fiber, jute, viscose fiber and acetate fiber, the materials have better oil absorption, can meet the requirement of oil storage, and have the advantages of high strength and good elasticity like terylene, cannot break and deform after being bent for many times, and have unique effect as the central strand of the steel wire rope.
The hexagonal rope 1 is formed by regularly twisting seven steel wire strands 11 according to '1+6', and a shaping layer 12 is wrapped outside the twisted body. The regular hexagonal rope strand is preferably adopted here, and is characterized in that the hexagonal surface contact form is more stable in structure, high in strength and small in relative friction compared with the round abutting form.
In particular, the shaping layers 12 are distributed at equal intervals along the length direction of the hexagonal rope strands 1, so that lubricating grease of the inner core can conveniently permeate into the hexagonal rope strands 1 while stabilizing the structure, the lubricating requirement of the steel wires is ensured, and the maintenance period of the steel wire rope is greatly prolonged.
Specifically, the strand 11 here includes a central steel wire 111, a plurality of inner layer steel wires 112 are uniformly wrapped around the outer circumference of the central steel wire 111, a plurality of outer layer steel wires 113 are uniformly wrapped around the outer circumference of the inner layer steel wire 112, and one central steel wire 111, nine inner layer steel wires 112 and nine outer layer steel wires 113 are exemplified in the figure, so that the sufficient strength of the strand 11 is ensured.
Further, grease is sprayed on the center steel wire 111, the inner layer steel wire 112 and the outer layer steel wire 113 respectively, and grease is filled in gaps of the steel wire strands 11, so that the inside of the steel wire is effectively lubricated, and the effects of preventing the steel wire from being corroded and reducing friction are achieved.
Wherein, the reinforcing strand 4 is twisted by a plurality of reinforcing wires, the reinforcing strand 4 is used for filling gaps, reducing the relative movement amount of the hexagonal strand 1 and improving the overall strength.
Preferably, the twisting direction of the reinforced strands 4 is opposite to that of the tubular core, so that the contact stress between the strands is reduced, the steel wire rope has excellent rotation resistance, and the condition that the steel wire rope is loose is reduced.
In addition, the outer surface of the wear-resistant coating layer 3 is coated with a polyurethane film, so that the surface wear resistance of the steel wire rope is further enhanced.
