Problems solved by technology

As we all know, the UIAA certified DYNAMIC power rope mainly has two indicators, the first impact force and the number of UIAA falls. However, there is currently no standardized method and standard for testing the safety performance of power climbing ropes in China, which makes power climbing ropes have great potential safety hazards.

Embodiment Construction

[0014] According to the use method of power climbing rope, it can be divided into single rope, pair rope and double rope. The dynamic mountaineering rope is a braided structure rope composed of a rope sheath 9 and a rope core 8. The safety performance test includes a structure and quality test, a rope sheath sliding test, a static elongation test, and a dynamic performance test.

[0015] Before testing the safety performance of the test sample, dry it for at least 24 hours, dry environment: temperature 50±5°C, relative humidity 10%; then, cool the sample for 2 hours, cooling environment: temperature 20±2°C, relative humidity not exceeding 65%; Then, precondition the sample for 72 hours, precondition the environment: temperature 20±2°C, relative humidity 65%; finally, test the sample, test temperature 23±5°C.

[0016] Structural and quality testing: The sampling length of single rope and pair rope test samples is 40 meters, and the sampling length of double rope test samples is...

Abstract

The invention discloses a testing method for safe performance of a power climbing rope, comprising a structure and quality test, a rope leather sliding test, a static force elongation ratio test and a dynamic performance test. The dynamic performance test comprises power elongation ratio, first falling impact force and falling times. Because the testing method is standard and scientific, and the testing data are correct and reliable, the security and the reliability of the power climbing rope are improved.

Description

technical field [0001] The invention belongs to the technical field of rope nets, in particular to a method for testing the safety performance of a power climbing rope. Background technique [0002] Power climbing rope is one of the components of mountaineering safety equipment, which is used to prevent climbers from falling accidentally during mountaineering or climbing. In projects with the possibility of power falling, power ropes must be used, such as rock climbing, mountain climbing, descent, bungee jumping, etc. At this time, the energy is absorbed by the extension of the rope. Power climbing ropes include single ropes, paired ropes and double ropes. A single rope refers to a rope that can be used alone during mountaineering to prevent falling; Climbers hold both ends of the rope to climb to prevent falling; double rope means that the middle part of the rope is fixed at a high place during mountaineering, and a climber holds both ends of the rope to climb at the same ...
