Light wear-resistant multifunctional composite power single rope and manufacturing method thereof

Abstract

An embodiment of the invention discloses a light wear-resistant multifunctional composite power single rope. The power single rope comprises a composite rope core and a rope skin which wraps the outside of the composite rope core, wherein the composite rope core is formed by compounding a first rope core fiber and a second rope core fiber, and the rope skin is formed by combining the first rope skin and the second rope skin at intervals in the axial direction of the power single rope. The first rope core fiber is a polyamide fiber, the second rope core fiber is a high-strength low-elongation fiber, and the first rope core fiber and the second rope core fiber are parallel, plied and compounded or braided and compounded to obtain the composite rope core; the rope skin is formed by weaving composite fiber strands, the first rope skin is formed by weaving with the pitch of 25-30 mm, and the second rope skin is formed by weaving with the pitch of 32-40 mm; the composite fiber strands are formed by compounding the polyamide fiber with the high-strength low-elongation fiber according to the number ratio of 4: 1; and the high-strength low-elongation fiber comprises one or a combination ofmore than one of ultra-high molecular weight polyethylene fiber, Vectran fiber, aramid fiber, carbon fiber and glass fiber.

Description

technical field

[0001] The application belongs to the technical field of special ropes, and in particular relates to a lightweight and wear-resistant multifunctional composite power single rope and a manufacturing method thereof. Background technique

[0002] Power rope climbing rope is divided into single rope, half rope and double rope. A single rope is a power climbing rope that can be used alone. It is used alone and is stressed separately to prevent climbers from falling. It is the most common type of rope. In use, a rope is hung into a protection point. When the climbing route is not very tortuous , mostly use this kind of rope. The single rope is not suitable for multi-stage descent, and is mostly used for sports climbing. It can be tightened when the rock climber falls. Because of its high extensibility, it can reduce the impact force of the falling person and improve the cushioning performance, thereby ensuring their personal safety.
