CN2073897U - Tetragonal type special torsionproof steel wire rope - Google Patents

Abstract

The utility model relates to a square-shaped special torsion proof steel wire rope. The utility model is characterized in that multiple strands of ropes are braided and twisted into a steel wire rope whose cross section is square by mutually braiding and twisting. When tensile force acts on the utility model, the internal stress of each strand of rope is mutually counteracted, and the utility model can not be twisted by the action of the internal stress. The utility model can be used for the guide rope of the drawn rope of the tension stringing in the high-voltage overhead transmission lines. The utility model can also be used as the rope which is required that the rope can not be twisted.

Description

Tetragonal type special torsionproof steel wire rope

The utility model belongs to the rigging field, is a kind of steel wire rope.

Steel wire rope is a kind of basic tool in lifting, traction, the hauling operation, has the following advantages: in light weight, intensity is high, elasticity is big, wear-resistant, load can withstand shocks.Flexible better, use flexibly.Running is stablized when high-speed cruising, does not have noise.Steel wire rope is the disrumpent feelings omen that fracture of wire is arranged, and whole steel wire rope can not rupture immediately.Steel wire rope is normally formed around sth. made by twisting by several strands of steel wires rope and a rope heart, what of steel wire rope rope strand can be divided into two kinds of sub-thread and multiplies by.The single-strand rope rigidity is better, is difficult for deflection, and multistrand rope is flexible better.No matter the steel wire rope of using is sub-thread or multiply at present, and the cross section is circle, and also promptly sub-rope cross section is circular, and it also is circular twisting with the fingers the cross section of compiling the steel wire rope that forms.Because steel wire rope is compiled in the sth. made by twisting process at sub-thread or multiply.Produce a kind of internal stress, this internal stress can be distributed on the cross section when steel wire rope is subjected to pulling force, and this power can make steel wire rope twist.This shortcoming of circular cross-section steel wire rope is restricted steel wire rope when some special applications, as makes the stringing guiding rope or the pull rope of electric power handling cable.

The purpose of this utility model is to propose a kind of the have various advantages of present circular section steel wire rope, the novel steel wire rope that does not twist because of internal stress again.

It is that round child rope sth. made by twisting volume forms that the utility model is achieved in that by 8 bursts of cross sections, and wherein 4 strands of left-hands and other 4 bursts of dextrad are compiled sth. made by twisting alternately, form the cross section of cubic type.

Description of drawings:

Fig. 1 is the external form figure that volume of the present utility model is twisted with the fingers;

Fig. 2 is a cross section of the present utility model son rope distribution map.

The utility model is owing to be that having adopted between 8 share ropes and 4 strands and 4 strands is that ordinary lay is weaved into positive square cross section, thus make that per share son restricts reverse internal stress to the center in cross section and cancel each other.So the utility model can not twist, and the internal stress of circular section steel wire rope distributes along cross section circle tangent line distribution.

The utility model can be used as the traction or the guiding rope of high pressure overhead power line tension stringing, also can be used for the rope of using that other require not reverse the aspect.

Claims (1)

1, the extraordinary anti-steel wire rope of turning round of square is to be formed around sth. made by twisting by the sub-rope of steel wire, it is characterized in that it being that 8 bursts of cross sections are done to compile alternately to twist with the fingers for 4 strands of left-hands and other 4 bursts of dextrad of circular child rope, forms tetragonal cross section.
