It is applicable to climbing ropes, but under normal conditions, falling incidents do not often occur, and not all ropes are used for human protection, so this standard has relatively large application limitations
Domestic testing standards for the basic performance of ropes have not yet been established, and no influential unified testing methods have been formed. Moreover, due to the rough processing of ropes, many manufacturers have not established sufficient awareness of the cutting resistance of ropes. However, with the types and functions of ropes The diversification and the expansion of the scope of application, such as the application in the fields of fire protection, first aid, military affairs, exploration, etc., the complexity of the application environment makes the requirements for the rope not only limited to the basic indicators such as strength, but also pays more attention to the resistance of the rope to friction and cutting. Etc performance
Therefore, in order to ensure that the rope fully exerts its safety guarantee function in production, life and other aspects, it is necessary to test the cutting resistance of the rope and establish a reasonable and scientific characterization method for cutting resistance. Currently, UIAA cut resistance The scope of use is limited, and the relevant domestic test methods are not suitable for the test of the cutting resistance of rope and belt products.

Embodiment Construction
[0014] The present invention simulates the cutting phenomenon in actual use, increases the tensile tension of the rope with cutting effect to make it break at the cutting place, and measures the cutting resistance of the rope through the cutting resistance coefficient. Concrete implementation steps of the present invention are:
[0015] (1) Test the cutting strength of the rope: figure 1 It is a structural schematic diagram of the test instrument used in the test method of a kind of rope cutting resistance performance of the present invention, adopting figure 1 The test apparatus shown tests the cutting strength of the rope.
[0016] (1) Sample preparation: for unused ropes, samples should be taken from places that pass the visual inspection; for used or used ropes, samples should be taken from places approved by relevant parties. Both ends of the sample should be firmly bound with adhesive tape or other materials, and the minimum length of the sample should not be less than...

The invention discloses a test method for anti-cutting performance of a rope belt, which comprises the following steps of: (1) testing the cutting force of the rope belt, wherein cutting forms with various cutting types and cutting angles can be tested and the cutting form in the actual service condition can be simulated to the greatest extent; (2) testing the breaking force of the rope belt; and (3) calculating the anti-cutting coefficient of the rope belt to judge the anti-cutting performance of the rope belt and intuitively reflect the anti-cutting performance of the material. The method is reasonable and simple, and the test data is accurate and intuitive.
Description
technical field [0001] The invention belongs to the technical field of detection, in particular to a method for testing the cutting resistance of rope and belt products. Background technique [0002] Through the novelty search of relevant patents, it is found that the cutting resistance test of the rope is a blank in the international scope. The only UIAA (International Mountaineering Federation) test method for the cutting resistance of power ropes is for mountaineering ropes. The specific method is that a rope with a certain weight impacts a certain sharp edge when the object falls, and the rope resists it. The number of such impacts measures the ability of the rope to resist being cut. It is applicable to climbing ropes, but under normal conditions, falling incidents do not often occur, and not all ropes are used for human protection, so this standard has relatively large application limitations. Domestic testing standards for the basic performance of ropes have not yet...
