Problems solved by technology

Ordinary limit ropes are made of 3 strands, 4 strands, 8 strands, 16 strands, 24 strands, and 48 strands braided into ropes and then buckled or braided at both ends. The strength of the whole rope is low, and the rope body and eye rings are wear-resistant. The performance is poor, and the wear status needs to be checked frequently in order to replace the rope during use. If it is not used properly, it will have certain safety hazards.

Embodiment 1

[0051] Step S11: Merge 5 ultra-high molecular weight polyethylene fibers with a specification of 1600D into 1 strand, and twist during the process of doubling.

[0052] Step S12: using a 320 braiding machine to braid 6 strands of S twist and 6 strands of Z twist into a rope core with a pitch of 9 times.

[0053] Step S13: Take a braided rope core and fold it in half, and mark the first half-fold point at the half-fold point, then make a second half-fold point, and mark two second half-fold points at the second half fold point. The rope ends on both sides of the first pair of folding points respectively pass through the inner side of the rope core from the second pair of folding points on the opposite side, and then both pass through the first pair of folding points, thereby forming an endless rope.

[0054] Step S21: Twist the nylon fiber with a specification of 840D through the twisting machine. The transmission belt of the twisting machine is tight and tight. The tension of ...

Embodiment 2

[0060] Step S11: merging 7 aramid fibers with a specification of 1500D into 1 strand, and twisting during the merging process.

[0061] Step S12: using a 320 braiding machine to braid 6 strands of S twist and 6 strands of Z twist into a rope core with a pitch of 9 times.

[0062] Step S13: Take a braided rope core and fold it in half, and mark the first half-fold point at the half-fold point, then make a second half-fold point, and mark two second half-fold points at the second half fold point. The rope ends on both sides of the first pair of folding points respectively pass through the inner side of the rope core from the second pair of folding points on the opposite side, and then both pass through the first pair of folding points, thereby forming an endless rope.

[0063] Step S21: Twist the aramid fiber with a specification of 1500D through the twisting machine. The transmission belt of the twisting machine is tight and tight. The tension of each fiber must be adjusted thr...

Abstract

The invention provides a limiting rope and a making method thereof. The limiting rope includes an annular rope 1, a rope sheath 2, a heat shrink tube 3 and a coating 4. The annular rope 1 penetrates through the hollow rope sheath 2, and the straightening length of the annular rope 1 is greater than the length of the rope sheath 2. The heat shrink tube 3 is arranged at the two ends of the rope sheath 2 and is used for fixing the annular rope 1 and the rope sheath 2. The coating 4 is applied to the exposed parts of the two ends of the annular rope 1 to provide protection for the annular rope 1.The limiting rope effectively exerts the characteristics of the limiting rope through the composite structure, while the weight is reduced, the strength and abrasion resistance are improved, and the service life of the rope is prolonged.

Description

technical field [0001] The invention relates to the technical field of ropes, in particular to a position-limiting rope, in particular to a position-limiting rope and a manufacturing method thereof. Background technique [0002] In the process of power maintenance, building construction, emergency rescue and other fields, there are many safety hazards in side operations and high-altitude operations. Among them, the safety and Ease of operation is paramount. Ordinary limit ropes are made of 3 strands, 4 strands, 8 strands, 16 strands, 24 strands, and 48 strands braided into ropes and then buckled or braided at both ends. The strength of the whole rope is low, and the rope body and eye rings are wear-resistant. The performance is poor, and the wear status needs to be checked frequently in order to replace the rope during use. If it is not used properly, it will have certain safety hazards. [0003] Therefore, there is an urgent need in this field for a position-limiting rope...
