[0003] The existing steel wire rope has low structural strength, and is prone to breakage under strong external force, with low service life. Therefore, a super high strength compaction strand galvanized steel wire rope is proposed. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides a super high strength compaction strand galvanized steel wire rope, which overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a super high strength compaction strand galvanized steel wire rope, comprising a core, the outer wall of the core is tightly attached to a plurality of steel wires I, the steel wires I are arranged in parallel, a protective sleeve is provided on the outer wall of the plurality of steel wires, a plurality of middle layer steel wires are spirally wound on the outer wall of the protective sleeve, a plurality of outer layer steel wires are spirally wound on the outer wall of the middle layer steel wires, the cross section of the middle layer steel wires is smaller than that of the outer layer steel wires, grooves are formed on one side of the outer wall of the steel wires I, the middle layer steel wires and the outer layer steel wires, protrusions are forged on the other side of the outer wall of the steel wires I, the middle layer steel wires and the outer layer steel wires, a galvanized coating is applied to the outer wall of the steel wires I, the middle layer steel wires and the outer layer steel wires, the core is made of carbon fiber, the middle layer steel wires are made of special alloy steel, and the outer layer steel wires are made of alloy steel, the special alloy steel is titanium-containing alloy steel:

[0006] When the steel wire rope is subjected to tension, the outer layer steel wire rope first bears part of the tension, due to its spiral twisting method and structure, the tension can be effectively transmitted to the middle layer strand rope, the middle layer steel wires further share the tension and transmit it to the inner core by virtue of higher strength, the reinforced structure of the core, especially the carbon fiber material, can stably bear the tension transmitted from the outer layer and the middle layer, while resisting possible extrusion deformation, ensuring the integrity and continuity of the entire steel wire rope when bearing tension, and thereby improving the overall strength of the steel wire rope.

[0007] The utility model discloses an advantageous effect: through the different twisting mode of steel wire rope, divide into rope core, middle layer and outer layer part, effectively disperse the tension of steel wire rope whole, simultaneously resist the extrusion deformation that can appear, guarantee the integrity and coherence of whole steel wire rope when bearing the tension, further improve the overall strength of steel wire rope, and the projection and the recess that set up on the rope core surface, through this concave-convex cooperation's mode, make the strand and the rope core between more closely combine together, ensure that when bearing the tension and the pressure, the connection between them does not slacken or break.
