High-performance triangular-strand steel wire rope

Abstract

The invention discloses a high-performance triangular-strand steel wire rope, which comprises six wire strands and a wire core. The six wire strands are uniformly twisted outside the wire core and arranged by forming 60-degree equant angles, and each wire strand is tangent with the wire core and is approximately triangular and comprises a strand core, three central steel wires, inner steel wires, middle steel wires and outer steel wires. The strand core is a circular steel wire strand formed by a plurality of steel wires, the three central steel wires are arranged on the periphery of the strand core by forming 120-degree equant angles and form a triangle shape with the strand core, the strand core and the central steel wires are wrapped by the inner steel wires, the middle steel wires are twisted on the outer periphery of the inner steel wires, and the outer steel wires are twisted on the outer periphery of the middle steel wires. Each strand core consists of forty six steel wires, and hardly any gaps are reserved among the inner steel wires, the strand core and the central steel wires. By twisting three times, the application range of the diameter of the steel wires and the range of the diameter of the steel wire rope can be maximized and flexibility of the steel wire rope is improved simultaneously.

Description

technical field [0001] The invention relates to a triangular-strand steel wire rope, in particular to a high-performance triangular-strand steel wire rope excellent in stability, torsion resistance, flexibility and reliability, and belongs to the technical field of steel wire rope products. Background technique [0002] The triangular strand steel wire rope is a special rope for mines. It is generally used for mine hoisting. It can also be used in construction projects. It is a very large consumption material. In the process of coal mining and large-scale building construction, the service life of the steel wire rope directly affects the work efficiency and safety. The service life of the ordinary steel wire rope is short, and the high-performance steel wire rope is mostly imported, and the cost is high; therefore, the development of high-performance triangular strands Wire rope is of great significance. Existing triangular strand steel wire rope, if attached image 3 , 4 ...

In the process of coal mining and large-scale building construction, the service life of the steel wire rope directly affects the work efficiency and safety. The service life of the ordinary steel wire rope is short, and the high-performance steel wire rope is mostly imported, and the cost is high; therefore, the development of high-performance triangular strands Wire rope is of great significance

Existing triangular strand steel wire rope, if attached image 3 , 4 As shown, it includes 6 strands 11 and a rope core 13; the 6 strands 11 are evenly twisted on the periphery of the rope core 13; each strand 11 is tangent to the rope core 13; the 6 strands 11 Arranged according to an angle of 60° equal division; the rope strands 11, the shape of the rope strands 11 is roughly triangular; comprising a strand core 12, a central steel wire 14, an inner layer steel wire 15, and an outer layer steel wire 16; the strand core 12 A circular steel wire strand formed by a plurality of steel wires; there are three central steel wires 14, which are arranged on the periphery of the core 12 and arranged in equal parts at 120° to form a triangular shape with the core 12; the inner steel wire 15 wraps the strands Core 12 and center steel wire 14; Described outer layer steel wire 16 is twisted on the periphery of inner layer steel wire 15; Described inner layer steel wire 15 is a group that is arranged around strand core 12 and center steel wire 14, is triangular; Said outer layer The steel wire is only tangent to the central steel wire; the outer steel wire is arranged on the periphery of the inner steel wire; the shape of the outer steel wire is also triangular; As a result, during use, when squeezed, twisted or bent, the steel wire in the strand will move to the gap area, resulting in uneven stress on the steel wire rope and bursting, shortening the service life and causing danger; At the same time, the rope strands are twisted twice, that is, the inner layer steel wire and the outer layer steel wire are twisted twice, and there is no breakthrough in the flexibility of the product and the diameter of the strand rope. The application diameter range of the steel wire and the diameter range of the wire rope are limited. limited, only small diameter steel wire ropes can be made
