Embodiment Construction

[0012] The present invention tests the friction phenomenon existing in actual use, repeatedly rubs the surface of the rope to make it white, and measures the friction resistance of the rope by the number of times of friction when the rope is white. figure 1 It is a structural schematic diagram of the test instrument used in the present invention, which is used to test the longitudinal friction resistance times and the transverse friction resistance times of the rope. Concrete implementation steps of the present invention are:

[0013] (1) Test the number of longitudinal friction resistance of the rope: (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 intercept. 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 1.5 meters.

Abstract

The invention discloses a testing method for friction resistance of a rope. The testing method comprises the following steps of: (1) testing the vertical friction resistance of the rope; (2) testing the lateral friction resistance of the rope; and (3) calculating the friction resisting times of the rope, and evaluating the friction resistance of the rope according to the friction resisting times of the rope. By using the testing method disclosed by the invention, the friction resisting times of the identical abrasive material and identical tension have comparability, and the friction resisting times of different abrasive materials and different tensions do not have comparability. The testing method disclosed by the invention has wide application range, is reasonable, simple and convenient, and is accurate and visual in the test data.

Description

technical field [0001] The invention belongs to the technical field of rope net detection, and in particular relates to a method for testing the friction resistance performance of a rope. Background technique [0002] By consulting relevant patents, it is found that there is no performance test on the friction resistance of ropes at present. The only one is the UIAA (International Mountaineering Association) test for the wear resistance of the power rope used for mountaineering. The specific device is to tie a 10 kg weight to the climbing rope and rub it longitudinally on the rotating sand wheel until the outer net of the rope is damaged. Wear out, the time when the rope is worn out directly reflects the longitudinal wear resistance of the rope. In actual use, the rope is subjected to horizontal friction as well as longitudinal friction, so this method has limitations. Domestic testing standards for the basic performance of ropes have not yet been established, and no influ...
