Embodiment Construction

[0012] A kind of QQSR structure special cable of the present invention is described in further detail below in conjunction with accompanying drawing:

[0013] figure 1 Among them, the QQSR structure special cable of the present invention is formed by twisting a steel wire core 2 around a steel wire rope 1 by seven steel wire ropes 1 .

[0014] The structure of the seven steel wire ropes 1 is 7×19S+6×7+1×7, which consists of a central strand core 11 with a 1×7 structure, six inner layer strands 12 with a 1×7 structure and seven 1×19S Structure The outer layer strand 13 is twisted once, and the inner layer strand 12 and the outer layer strand 13 are in a line contact state. The twisted structure is tight and stable, and the filling factor and breaking force of the cable are large.

[0015] The structure of the steel wire rope core 2 is 7×19S+6×7+1×7, which consists of a central strand 21 with a 1×7 structure, six inner strands 22 with a 1×7 structure and seven outer layers with...

Abstract

The invention discloses a QQSR structured special cable which is formed by twisting seven steel wire ropes around one steel wire rope core. One 1*7 structured center strand core, six 1*7 structured inner stranded ropes and seven 1*19S structured outer stranded ropes are twisted once to form each of the seven steel wire ropes, one 1*7 structured center strand, six 1*7 structured inner strands and seven 1*19S structured outer strands are twisted once to form the steel wire rope core, the strands of the cable are in a line contact state, the twisted structure is compact and stable, and cable filling coefficient and breaking force are large. The cable is large in diameter and good in flexibility, the bearing capacity of the cable is greatly improved, and the requirements of major engineering construction for the special cable are met.

Description

technical field [0001] The invention relates to a special cable with a QQSR structure, which belongs to the technical field of metal products. Background technique [0002] The diameter of the existing thick-diameter cables is generally more than 60mm, and the maximum can reach 190mm. The breaking force and bearing capacity are small, and the cable structure is complicated, the production is difficult, the flexibility is poor, the structure is elongated, and it cannot meet the needs of major engineering construction. Bundled steel wires and cables have high rigidity and poor flexibility, and cannot meet the requirements of special environments. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a special cable with QQSR structure, solve the technical problems of small diameter, poor flexibility and fatigue performance of the special cable, and meet the demand for special cables in major engineer...
