[0010] After adopting the above structure, the beneficial effects of the utility model are:

[0011] The utility model can reduce noise when the central strand, the outer strand and the reinforcement strand are squeezed against each other by arranging multiple silent layers and sound-absorbing cotton, thereby improving the silent effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the present utility model.

[0013] Description of reference numerals:

[0014] 1 center strand, 11 first steel wire, 12 first protective cover, 13 first sound-proof layer, 2 outer strands, 21 second steel wire, 22 second protective cover, 23 second sound-proof layer, 3 reinforcing strands, 4 filling sound-absorbing cotton, 5 moisture-proof layer, 6 third sound-proof layer, 7 wear-resistant layer. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See Figure 1 A silent steel wire rope comprises a central strand 1, an outer strand 2 and a reinforcing strand 3, the central strand 1 being twisted by a plurality of first steel wires 11 and provided with a first protective cover 12 on the outside, and a first silent layer 13 being provided on the outside of the first protective cover; the outer strand 2 comprises a plurality of outer rope strands and is twisted around the outside of the central strand, the outer rope strand being twisted by a plurality of second steel wires 21 and provided with a second protective cover 22 on the outside, and a second silent layer 23 being provided on the outside of the second protective cover; the reinforcing strand 3 is provided in the gap between the outer strand 2 and the central strand 1, and the gap between the central strand 1, the outer strand 2 and the reinforcing strand 3 is filled with sound-absorbing cotton 4; the outer strand 2 and the reinforcing strand 3 are wrapped with a moisture-proof layer 5, the moisture-proof layer 5 is wrapped with a third silent layer 6, and the third silent layer 6 is wrapped with a wear-resistant layer 7. Specifically, by arranging the first silent layer 13 and the second silent layer 23 on the outside of the central strand 1 and the outer strand 2 respectively, and then filling the sound-absorbing cotton 4 in the gaps between the central strand 1, the outer strand 2 and the reinforcing strand 3, the noise of the central strand 1, the outer strand 2 and the reinforcing strand 3 is reduced when they are squeezed, thereby improving the silent effect.

[0018] In this embodiment, the first silent layer 13, the second silent layer 22 and the third silent layer 6 are all made of polyester fiber sound-absorbing cotton. The polyester fiber sound-absorbing cotton silent layer is convenient for absorbing the noise generated inside the steel wire rope.

[0019] In this embodiment, the wear-resistant layer 7 is an aluminum oxide wear-resistant layer, which makes the steel wire rope have excellent wear resistance.

[0020] In this embodiment, the outer surface of the wear-resistant layer 7 is coated with tungsten carbide to further improve the wear resistance of the steel wire rope.

[0021] In this embodiment, the moisture-proof layer 5 is a honeycomb-shaped aluminum film layer.

[0022] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
