Embodiment 1

[0026] Embodiment 1: a kind of anti-rebound rope, such as figure 1 , figure 2 As shown, it is formed by twisting multiple strands 1. Such as figure 2 , image 3 As shown, the rope strand 1 includes an inner core fiber 11 and an outer covering fiber 12 located on the outer layer of the inner core fiber 11, the inner core fiber 11 and the outer covering fiber 12 are twisted to form a rope strand 1, and the outer covering fiber 12 wraps the inner core fiber 11. The fiber elongation of the inner core fiber 11 is greater than the fiber elongation of the outer fiber 12, and the inner core fiber 11 is a polyamide fiber with a fiber elongation of 14-28%. Outsourcing fiber 12 selects ultrahigh molecular polyethylene fiber for use.

Embodiment 2

[0027] Embodiment 2: An anti-rebound rope, the difference from embodiment 1 is that the anti-rebound rope is braided by a multi-strand strand 1 through a rope braiding machine.

Embodiment 3

[0028] Embodiment 3: An anti-rebound rope is formed by twisting multiple strands 1 . The rope strand 1 includes an inner core fiber 11 and an outer covering fiber 12 located on the outer layer of the inner core fiber 11 , and the inner core fiber 11 and the outer covering fiber 12 are twisted to form a rope strand 1 . The fiber elongation of the inner core fiber 11 is greater than the fiber elongation of the outer covering fiber 12, and the inner core fiber 11 selects polyester fibers with a fiber elongation of 10-18%. Outsourcing fiber 12 selects ultrahigh molecular polyethylene fiber for use.

Abstract

The invention discloses an anti-rebound rope. The anti-rebound rope comprises multiple strands, each strand comprises inner core fibers and outer packing fibers located on the outer layer of the corresponding inner core fibers, wherein the fiber elongation rate of the inner core fibers is larger than that of the outer packing fibers. The anti-rebound rope has the advantages that in the strands ofthe anti-rebound rope, the fiber elongation rate of the inner core fibers is larger than that of the outer packing fibers, so that when the anti-rebound rope is broken due to overload, the outer packing fibers are broken at first, and the inner core fibers are not broken immediately due to the larger fiber elongation rate; rebound force is released gradually during breaking of the outer packing fibers, so that the rebound force is reduced after the anti-rebound rope is broken, and then the effects of rebound prevention and safe use are achieved.

Description

technical field [0001] The invention relates to the field of ropes, in particular to an anti-rebound rope. Background technique [0002] With the development of my country's economy, ropes made of ultra-high molecular weight polyethylene fibers or aramid fibers are widely used in national defense and civil aviation. The rope made of ultra-high molecular polyethylene fiber or aramid fiber, the fiber elongation of ultra-high molecular polyethylene fiber or aramid fiber is low, and the rebound force is relatively large when the rope is broken after overloading, which is easy to cause personal injury and cause security incident. Contents of the invention [0003] The object of the present invention is to provide an anti-rebound rope with anti-rebound effect. [0004] The above-mentioned technical purpose of the present invention is achieved through the following technical solutions: an anti-rebound rope, comprising a multi-strand strand, the strand comprising an inner core f...
