Description

Three-in-one power climbing rope, manufacturing method thereof and three-in-one power climbing rope equipment

Technical Field

The application belongs to the technical field of fiber ropes, and particularly relates to a three-in-one power climbing rope, a manufacturing method of the three-in-one power climbing rope and three-in-one power climbing rope equipment.

Background

The mountain-climbing and rock-climbing sports are popular sports. Equipment for mountain climbing and rock climbing mainly has two purposes: one is to ensure the safety of the sport, and the other is to make the performance of the climber more excellent. Among them, the power climbing rope is always the most important equipment in the mountain-climbing sport. The dynamic climbing rope has high extensibility usually so as to reduce the influence on the descending of mountaineers and facilitate operation, and can be used as a climbing rope, and the dragging load of the climbing rope can be buffered on a huge wall surface, a cliff or a cave.

The dynamic climbing rope is divided into a single rope, a half rope and a double rope. The single rope is a power mountain climbing rope which can be used singly, is used independently and stressed independently, prevents climbers from falling, is the most common rope type, one rope is hung into a protection point in use, when a rock climbing route is not very tortuous, the multi-stage rope is mostly used, and the single rope is not suitable for descending and is mostly used for sports climbing. Half rope is the power climbing rope that uses in pairs, prevents that the pioneer from climbing the person and falling, must hang the protection lock simultaneously with the double-stranded rope when using half rope, and the leader is tied double-stranded rope on the safety belt simultaneously, and two are tied one of them rope respectively on the safety belt along with the person of climbing, and half rope is compared the advantage of single rope and is that the multistage descends comparatively conveniently. The double ropes are power mountain climbing ropes used in parallel in pairs, the two ropes are used simultaneously, different protection points are inserted to prevent a climber from falling, the double ropes consist of double ropes, the two ropes are tied to a safety belt simultaneously by a climber and a climber along with the climber, the tortuous path can be reduced, the rope is mainly used for climbing mountains or climbing long paths, the advantages are more obvious in multi-stage descending, the double ropes are safe when the protection points are not very firm in the climbing process, the impact force generated by a single double rope to the protection points is smaller than that of a half rope or a single rope in falling, when stones or ridges fall, the double ropes can provide better protection for the climber, and when the rock climbing path is changeable and the falling impact force is reduced as much as possible, the double ropes are hung in the protection lock respectively.

However, the mountain climber carries a plurality of different types of mountain climbing ropes to go out, and the mountain climbing rope is selected for use, so that the mountain climbing rope is not only troublesome to use, but also increases the load of the mountain climber, and is not beneficial to the development of rock climbing movement and the safety protection of the mountain climber.
