The outer layer is covered with a smooth nylon sheath, and the main function is to protect heart. During climbing, heart and the sheath are prone to slipping off when subjected to large axial and tensile forces, and thus dangerous. Therefore, the traction rope for climbing is subjected to slipping test before leaving a factory, and can be normally sold after being qualified. However, in the use process of the conventional rope sheath-core sliding tester, after a detector passes through a central hole of the tester, 35 KG weights need to be manually hung on the tester, and then the detector pulls the rope manually; especially after the pulling is finished, the tester still needs to manually take down the weight and then reset the rope, and then repeat the above actions for 5 times. The detecting instrument and the operating method are time-consuming and labor-consuming, and inaccurate in data due to unstable speed of each pulling. In addition, according to the actual feedback of a rope user, even if the sliding length of the sheath of the rope, which is tested by the method, is zero, the sheath sliding phenomenon still occurs in the using process, which indicates that the tester can only simulate and characterize the sliding of the sheath of the rope and cannot perform equivalent test.
