the outer ply comprises: the third rope core is spirally twisted on a plurality of outer layer strand thin steel wires outside the third rope core, and a plurality of outer layer strand thick steel wires spirally twisted outside the third rope core;
the outer layer strand is coated with a wear layer.
Furthermore, the first rope core is formed by spirally twisting a plurality of polyester fiber yarns.
Furthermore, lubricating grease is filled in the first rope core.
Furthermore, the second rope core is formed by spirally twisting a plurality of carbon fiber yarns.
Furthermore, the third rope core is formed by spirally twisting a plurality of round steel wires.
Further, the wear-resistant layer is made of polyurethane resin materials.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) The utility model discloses a wire rope is arranged to rope through first rope core, inlayer thigh and the mutual spiral of outer thigh hand over twist with one another, makes it connect closely, reduces its wearing and tearing each other, has increased the holistic intensity of wire rope simultaneously.
(2) The utility model discloses a wire rope is used to rope row through setting up the first rope core that a plurality of polyester fiber spiral twists with fingers and constitute for the oil storage makes the oil on wire rope surface obtain lasting replenishment, makes wire rope durable for a long time.
(3) The utility model discloses a wire rope for rope row, the second wick that a plurality of carbon fiber silk spiral intertwine constitute, the tensile strength of carbon fiber silk is several times of ordinary steel core, when wire rope takes place the distortion, the second wick of carbon fiber silk is difficult for taking place disconnected strand phenomenon; therefore, tensile, impact, torsion and abrasion resistance of the steel cord can be increased.
(4) The utility model discloses a wire rope is used to rope row through setting up the third rope core that a plurality of round steel silk spiral alternate twists with fingers and constitute, can increase wire rope's tensile, crushing resistance, and structural stability is good simultaneously, makes wire rope can use under high temperature, abominable environment.
(5) The utility model discloses a wire rope is arranged to rope, through the wearing layer that sets up polyurethane resin for increase the wearability on wire rope surface.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1, the utility model relates to a wire rope is used to rope row, include: the rope comprises a first rope core 1, six inner layer strands 2 spirally twisted outside the first rope core 1, and six outer layer strands 4 spirally twisted outside the inner layer strands 2; the inner layer strand 2 comprises: a second rope core 21, and six inner layer strand steel wires 22 helically twisted outside the second rope core 21;
the outer strands 4 comprise: a third rope core 41, a plurality of outer strand thin steel wires 42 helically twisted outside the third rope core 41, and a plurality of outer strand thick steel wires 43 helically twisted outside the third rope core 41;
the outer strands 4 are externally coated with a wear layer 3.
The first cord 1 of the present embodiment is formed by spirally twisting a plurality of polyester filaments, and the first cord 1 is filled with lubricating grease.
The polyester fiber yarn is made of high polymer fiber materials and can be used for storing oil, so that the oil on the surface of the steel wire rope is replenished for a long time, and the steel wire rope is durable for a long time.
The second cord 21 of the present embodiment is formed by spirally twisting a plurality of carbon fiber filaments.
The tensile strength of the carbon fiber wire is several times that of a common steel core, and when a steel wire rope is twisted, a second rope core of the carbon fiber wire is not easy to break; therefore, tensile, impact, torsion and wear resistance of the steel wire rope can be increased.
