Description

Multi-strand anti-rotation steel wire rope

Technical Field

The utility model relates to an anti rotatory wire rope technical field, more specifically says, the utility model relates to an anti rotatory wire rope of stranded.

Background

The steel wire rope is a spiral steel wire bundle formed by twisting steel wires with mechanical property and geometric dimension meeting requirements together according to a certain rule, and consists of the steel wires, a rope core and lubricating grease. The steel wire rope is a spiral rope which is formed by twisting a plurality of layers of steel wires into strands, and then twisting a certain number of strands by taking a rope core as a center. In a material handling machine for lifting, pulling, tensioning and carrying. The multi-strand anti-rotation steel wire rope is one of steel wire ropes, and has small rotating force and wide application range.

The national intellectual property office in 2015.01.21 discloses a utility model patent of an announcement number CN204112151U, title "a rotatory mixed twist wire rope of anti-rotation", this an anti-rotation mixed twist wire rope, including right twist and left twist, wire rope comprises the same right twist of quantity and left twist, and the direction of twist of each adjacent layer thigh is opposite, promptly right twist and left twist NULL, and the upper and lower floor's thigh of arbitrary right twist is left twist, and the upper and lower floor's thigh of arbitrary left twist is right twist. An anti rotatory mixed wire rope that twists with fingers has mutual wire rope and syntropy wire rope's advantage, each syntropy strand alternate arrangement in the rope has increased the contact surface of steel wire, mechanical properties is also better than mutual wire rope and syntropy wire rope that twists with the fingers, through right the utility model discloses a mechanical properties tests and adhesive strength are experimental, select the same raw materials for use, break the pulling force and improved 12% than the mutual wire rope that twists with the fingers of same specification, improved 20% than the mutual wire rope that twists with the fingers of same specification with the adhesive strength of rubber.

But when in actual use, because the more outer thigh of wire rope lacks the fastening and blocks for when wire rope uses, the loose condition appears very easily, influences wire rope's normal use, for this reason the utility model provides an anti rotatory wire rope of stranded.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The multi-strand anti-rotation steel wire rope shown in the attached drawings 1-3 comprises a steel wire rope body 1, wherein the steel wire rope body 1 is sequentially provided with an inner strand 11 and an outer strand 12 which are twisted into a strand by wrapping a plurality of strands from inside to outside, the inner strand 11 and the outer strand 12 are respectively wound in a spiral line mode by taking the cross section center line of the steel wire rope body 1 as the center, the twisting directions of the inner strand 11 and the outer strand 12 are opposite, the outer surface of the outer strand 12 is tightly sleeved with an upper pressing hoop 2 and a lower pressing hoop 3, two ends of the upper pressing hoop 2 and two ends of the lower pressing hoop 3 are respectively and fixedly connected with an upper connecting convex part 4 and a lower connecting convex part 5, a plurality of fastening bolts 6 are arranged inside the upper connecting convex part 4 and the lower connecting convex part 5, the inner wall surfaces of the upper pressing hoop 2 and the lower pressing hoop 3 are respectively and tightly abutted against the outer strand 12, and the bottom of the upper connecting convex part 4 and the top of the lower connecting convex part 5 are tightly abutted against each other;

the twisting directions of the inner layer strand 11 and the outer layer strand 12 are opposite, when the steel wire rope body 1 is subjected to relevant acting force, the twisting directions of the inner layer strand 11 and the outer layer strand 12 of the strands are opposite, namely, torque is opposite, and friction forces of the inner layer strand 11 and the outer layer strand 12 of the strands are just counteracted with each other, so that balance is formed, the steel wire rope body 1 is well prevented from rotating, and further the relative stability of an object on the steel wire rope is well improved.
