Abstract

The utility model relates to a steel wire rope with four strands. The steel wire rope with the four strands comprises a rope core and the four strands which are mutually winded on the rope core, wherein 31 steel wires are arranged in each strand, a cross section of each strand is of a regular hexagon shape, and the strands are arranged around the rope core in a square mode. The steel wire rope with the four strands has the advantage that the special arrangement of steel wires in each strand effectively improves the mechanical strength of the steel wire rope.

Description

A kind of steel wire rope of four rope strands

Technical field

The utility model relates to a kind of steel wire rope, particularly relates to a kind of steel wire rope of four rope strands.

Background technology

Steel wire rope is the flexible cable that is twisted into by many or multiply finer wire, and it is to be twisted thigh by the multilayer steel wire, centered by wire rope core, twists with the fingers helically wound rope by some thighs again.In material carrying machine, for promote, traction, tension and carrying.The intensity of steel wire rope is high, from heavy and light, stable working, be difficult for suddenly whole root fracture, reliable operation.

Because steel wire rope is in being usually used in high-risk operations, therefore, its safety and stability is very important, steel wire rope of the prior art, Shortcomings all aspect TENSILE STRENGTH and resistance to elevated temperatures.

The utility model content

The purpose of this utility model is in order to solve the existing defective of steel wire rope in the prior art, to provide a kind of steel wire rope with more high-intensity four rope strands to solve the problems referred to above.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of steel wire rope of four rope strands comprises wire rope core; With

On wire rope core mutually around together 4 strand thighs, the cross section of described rope strand be shaped as regular hexagon,

Wherein, described rope strand is square arrangement in the wire rope core periphery.

As preferred version, the steel wire quantity in the described rope strand is 31.

As preferred version, the steel wire in the described rope strand is divided into four layers, is respectively from inside to outside ground floor, the second layer, the 3rd layer, the 4th layer, and wherein, the ground floor steel wire is 1, and second layer steel wire is 6, and the compound steel silk is 12, and the 4th layer of steel wire is 12.

As preferred version, the ground floor gauge of wire in the described rope strand is 0.51mm; Second layer gauge of wire is 0.46mm; In the compound steel silk, it is 0.5mm that 6 gauges of wire are arranged, and it is 0.38mm that 6 gauges of wire are arranged; The 4th layer of gauge of wire is 0.65mm.

As preferred version, the alternate combination of the steel wire that described compound steel silk is diameter 0.5mm and the steel wire of diameter 0.38mm.

The beneficial effect that the utlity model has: in every rope strand the special setting Effective Raise of steel wire the mechanical strength of steel wire rope.

Description of drawings

Fig. 1 is structure chart of the present utility model;

Fig. 2 is the enlarged drawing of rope strand in the utility model.

The specific embodiment

Further understand and understanding for making architectural feature of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:

Referring to Fig. 1, on the wire rope core 100 mutually around being the 4 strand thighs 210,220,230 and 240 of square arrangement.

Referring to Fig. 2, because the structure of each rope strand is identical, therefore only introduce the structure of each rope strand as an example of rope strand 210 example, steel wire quantity in the rope strand 210 has 31, steel wire is respectively from inside to outside: 1 diameter is the second layer steel wire that steel wire 212 that the ground floor steel wire that forms of 0.51mm steel wire 211,6 diameters are 0.46mm forms, the compound steel silk that the steel wire 2132 alternate settings that the steel wire 2131 that 6 diameters are 0.38mm and 6 diameters are 0.5mm form, and the 4th layer of steel wire forming of 6 diameters steel wire 214 that is 0.65mm.

When steel wire is twisted with the fingers thigh, be coated with first one deck lubricating oil on the every steel wire, when closing rope, on wire rope core, also smear one deck lubricating oil, the steel wire of rope strand is through zinc-plated steel wire, and the material of wire rope core is selected the composite of carbon fiber and polyimide fiber, Effective Raise the TENSILE STRENGTH of steel wire rope.

In sum, it only is preferred embodiment of the present utility model, be not to limit the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature and spirit change and modify, and all should be included in the claim scope of the present utility model.
