Sharp corner resistance testing device and method for rope

Abstract

The invention provides a sharp corner resistance testing device and method for a rope. The sharp corner resistance testing device comprises a base, a first fixing frame, a second fixing frame, a fixing clamp and a driving shaft; an electric control switch and an emergency stop button are arranged on the base; a first sliding rail is arranged on the first fixing frame, the first fixing frame and the base are fixedly connected, and a pulley is arranged on the first sliding rail; the first sliding rail is used for adjusting the height of the rope fixed to the pulley; a second sliding rail is arranged on the second fixing frame which is fixed to the base, the second sliding rail and a sharp block are fixedly connected through a connecting rod, and the second sliding rail is used for limiting the moving direction of the sharp block; the fixing clamp is arranged on the base and used for fixing the rope; and the driving shaft makes contact with the sharp block and is used for driving the sharp block to move. According to the sharp corner resistance testing device and method for the rope, the sharp corner resistance degree of the rope can be tested more accurately, operation is convenient,and the automatic degree is high.

Description

technical field [0001] The invention relates to the technical field of rope detection, in particular to a rope sharp-angle resistance test, in particular to a rope sharp-angle resistance test device and a test method thereof. Background technique [0002] At present, rope products are widely used, especially in the fields of exploration, rescue and military. Different application environments have different quality requirements for ropes. For ordinary rope products, people pay attention to their breaking strength and elongation at break. and other mechanical performance indicators. During the use of the rope, it usually comes into contact with sharp objects. Sharp objects can cause great harm to the rope, especially in exploration and rescue scenarios. The durability of the fiber rope determines the safety level of rescue and exploration. . [0003] At present, only the International Mountaineering Federation has proposed the detection concept of the sharp-angle resistance...

AI Technical Summary

Problems solved by technology

The test instrument system for the basic performance of domestic fiber ropes has not yet been established, there is no test method for the sharp-angle resistance performance, and there is no corresponding testing equipment, and because the domestic rope processing is not refined enough, the sharp-angle resistance performance of the rope has not been established. enough awareness
