AI Technical Summary
In existing technologies, the test results of safety ropes vary greatly due to different operating methods in the safety belt performance test, and the knotting method is prone to stress concentration and breakage, making it difficult to achieve rapid and accurate testing.
The system employs a detachable front and rear rope winding device to keep the safety rope on the same axis during testing. The length of the safety rope can be adjusted to meet national standards, preventing knots and damage to the rope. The safety rope is secured using a detachable rope winding shaft and a reinforcing pressure plate.
It enables precise adjustment of the safety rope length, avoids breakage caused by knots, improves the accuracy and efficiency of testing, and reduces the difficulty of operation.
