Triangular strand wire rope

Abstract

The invention discloses a triangular strand wire rope, which comprises six rope strands and a rope core. The six rope strands are twisted uniformly outside the rope core, each of the rope strand is tangent with the rope core; the six rope strands are arranged according to a uniformly divided angle of 60 DEG; the appearance of the rope strand is substantially triangular, the rope strand comprises a strand core, three central wires, inner wires and outer wires; the strand core is a round wire strand formed by a plurality of wires; the three central wires are arranged according to a uniformly divided angle of 120 DEG, and form a triangle coordinated with the strand core; the inner wires wrap the strand core and the central wires; the outer wires are twisted outside the inner wires; the inner wires are tangent with the central wires and the strand core receptively; the outer wires are tangent with the inner wires. According to the invention, constituent elements have no interspaces between each other, so that the problems of shelling, getting loose and being poor in anti-torsion performance during the working process can be avoided, the high stability, high anit-torsion performance and high reliability of the wire rope can be obtained, and the service life of the product is improved.

Description

Technical field [0001] The invention relates to a triangular-strand steel wire rope, in particular to a triangular-strand steel wire rope that can effectively solve the gaps of the steel wire rope strands, improve product stability, torsion resistance and reliability, and has low use cost, and belongs to the cutting-edge technology field of steel wire rope products. Background technique [0002] Triangular strand steel wire rope is a special rope for mines. It is generally a steel wire rope 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 steel wire ropes directly affects work efficiency and safety. The service life of ordinary steel wire ropes is short, while high-performance steel wire ropes are mostly imported and costly; therefore, high-performance triangular strands have been developed The wire rope has very important significance....

Problems solved by technology

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 force on the steel wire rope and bursting, shortening the service life and causing danger
