Embodiment 1

[0022] like Figure 1-Figure 5 As shown, a high load-bearing steel wire rope for hoisting is formed by twisting six outer strands 1 symmetrically wrapped around a metal core, and the metal core includes a twisted metal core central strand 3 and a metal core outer strand 2. The outer layer strand 1 is a compacted strand of the Silu-Valenton composite structure, and the outer layer strand 2 of the metal core and the central strand 3 of the metal core are point contact structures.

[0023] The outer layer strand 1 is a compacted strand formed by twisting a central steel wire with 30 steel wires of 3 different diameters in total, and is in the form of a Siru-Walington composite structure.

[0024] The outer strands 2 of the metal core and the central strand 3 of the metal core are twisted by 6 steel wires wrapped around one central steel wire, and are in a point contact structure.

[0025] Its preparation method is:

[0026] On the stranding car, the steel wires are arranged thr...

Abstract

The invention relates to a steel wire rope with high bearing capacity for lifting and a preparation method thereof. The steel wire rope is prepared by wrapping and twisting a metal core by six outer strands symmetrically, wherein the metal core comprises a metal core central strand and a metal core outer strand which are twisted together; the outer strand is a compact strand in a seale-warrington composite structure; and the metal core outer strand and the metal core central strand are in a point contact structure. The preparation method comprises the following steps: wrapping and twisting the six outer strands on the metal core, twisting, and rolling by two groups of orthogonal rollers to form the steel wire rope product. The steel wire rope of the invention has the following beneficial effects: the bearing capacity is higher, the minimum breaking force coefficient can reach 0.44, the structure breaking force can reach 776KN, the weight coefficient can reach 0.48, the structure hectometer weight can reach 432KG, and the extrusion resistant capacity is improved; and the compaction is carried out twice during stranding and rope twisting, the steel wires are tightly meshed mutually, and the wear-resistant property is improved.

Description

technical field [0001] The invention relates to a steel wire rope and a preparation method thereof, belonging to the technical field of ropes. Background technique [0002] Due to the rapid development of the machinery industry, the load-bearing capacity of hoisting tools is required to be higher and higher. As far as steel wire ropes are concerned, the load-bearing capacity of steel wire ropes is required to be higher and higher under the same specifications. Point-contact wire ropes and line-contact wire ropes are used more frequently, and the load-carrying capacity cannot meet the requirements, and some machines can no longer undertake the lifting task. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of existing steel wire ropes, and provide a high-load-bearing steel wire rope for lifting with high load-bearing capacity, strong wear resistance and extrusion resistance and a preparation method ther...
