CN2089017U - Special square 12 strand anti-twist steel cable - Google Patents

Abstract

The utility model relates to a special square 12 strand anti-twist steel rope, which is a steel rope. The utility model is characterized in that the steel rope is twisted by the method that multiple strands of ropes are mutually twisted together, and the cross section of the utility model is in a square shape. Owing to the mutual cancellation of the tetragonal core of the section of the resultant moment, the no rotation and no twisting of the steel rope can be realized when the stress acts on the utility model. The problems of corrosion prevention and rust prevention of the original steel rope braided by tetragonal eight strands of ropes can be solved, and the maintenance cost of the utility model can be reduced. The utility model can be used in the relevant technical fields of mines, coal mines, cranes with big delivery lifts, marine vehicles, quays, the construction of power transmission lines, etc.

Description

Special square 12 strand anti-twist steel cable

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

Anti-rotation steel wire rope is a kind of high-performance steel wire rope that is widely used in industrial circles such as the construction of high voltage power transmission and transforming station, harbour, elevator hoist, compare with ordinary steel rope, have not beat and turn round, non-rotary characteristics, this provides great convenience for many industrial application.My unit is the utility model patent to " anti-rotation steel wire rope planar textile mechanism " of Patent Office of the People's Republic of China's application on October 5th, 90, application number is 90215937,2, this device can knit out the anti-steel wire rope of turning round of square stereotyped writing, yet, this steel wire rope place of people's will to the greatest extent still in distress, be sub-thread diameter when big, pliability, flexible undesirable, and can't add weak point such as core braiding.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and provides the special type of 12 strands of a kind of squares to prevent turning round steel wire rope.

It is that circular child rope sth. made by twisting volume forms that the utility model is achieved in that by 12 bursts of cross sections.Wherein six roots of sensation left-hand lay, six roots of sensation right-laid are compiled alternately and are twisted with the fingers the steel wire rope that forms the square cross section.

Further specify below in conjunction with accompanying drawing:

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

Accompanying drawing 2 is a cross section of the present utility model son rope distribution map;

See accompanying drawing 1,2, the utility model is owing to be to have adopted 12 share ropes, and be that mutual the volume twisted with the fingers the quadrate cross section between six strands and six strands, six bursts of left-hand lays, six bursts of right-laid, thus this its resultant moment of 12 share rope torsion is cancelled out each other at the square kernel of section, himself has the stressed feature of not turning round of not revolving and make, when the pulley, because the density in its cross section is better, it is smaller to be out of shape more original cubic kernmantle.

The utility model is compared with the steel wire rope of original square stereotyped writing, in ability to bear In the identical situation, its flexible, toughness, own vol all is better than the former, can be widely used in mine, colliery, big lift crane, boats and ships, harbour, power transmission sequence and the relevant field such as set up.

Claims (1)

1, the anti-steel wire rope of turning round of 12 bursts of special types of square is to be compiled to twist with the fingers by steel wire rope to form, and it is characterized in that it being that 12 bursts of cross sections are circular child rope, and six strands of left-hands and six bursts of dextrad are done mutual the volume and twisted with the fingers, and form tetragonal cross section.
