The electric telescopic rod 16 extends, driving the clamping plate 15 connected to it to move until the clamping plate 15 tightly clamps the knot, fixing the wire rope to be tested inside the device. The servo motor 2 is then started, driving the lead screw 7 fixedly connected to it to rotate. The rotation of the lead screw 7 causes the movable plate 9 to move in the direction of the lead screw 7, pulling the wire rope. The tension sensor 14 detects the tension on the wire rope in real time. When the force detected by the tension sensor 14 suddenly becomes 0, the wire rope breaks. The maximum value detected by the tension sensor 14 is the maximum tension of the wire rope. During this process, the air compressor 3 is in operation. The operation of the air compressor 3 can blow compressed air into the inner cavity of the blower plate 11. The side wall of the blower plate 11 is evenly provided with through holes. The air in the inner cavity of the blower plate 11 is blown out through the through holes. The blown air can intercept the debris generated by the broken wire rope, reduce the probability of debris hitting the observation window 10, and extend the service life of the observation window 10. When it is necessary to clean the debris in the device, the servo motor 4 is started. The servo motor 4 drives the synchronous roller connected to it to rotate. The synchronous roller drives the conveyor belt 8 to rotate. The conveyor belt 8 moves the debris that falls on it. When the debris is moved, it is collected in the collection box 6, realizing the rapid cleaning of debris. In addition, during the debris cleaning process, the air blown out by the blower plate 11 can blow away the debris that falls in the device.
