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.
