When the fatigue test on an inelastic rope or cable is performed, the fixation of the counterweight assembly and the supporting assembly is cancelled, thereby effectively reducing the difficulty of operation. The second liftable roller can lift up the counterweight assembly connected to the inelastic rope or cable, thereby avoiding collision of the counterweight assembly during the detection process.

At this time, the elastic rope is in an initial tightened state, which is approximately equal to the original length of the elastic rope. The second lifting block continues to rise until the elastic rope is pulled to a set displacement or broken, and the displacement sensor value and the tension value at this time node are recorded, thereby realizing the tensile force detection of the elastic rope. Through the automatic calibration of the initial length of the elastic rope, the detection difficulty can be effectively reduced and the accuracy of the tensile value detection of the elastic rope can be improved.

[0029] When testing the tension of the elastic rope, the two ends are fixedly installed on the first hanging ring 18 and the fourth hanging ring 81 respectively. The second lifting block 73 moves up to make the value of the tension meter 8 reach the first threshold value, and the value of the displacement sensor 75 at this time is recorded. At this time, the elastic rope is in an initial tensioned state, and the second lifting block 73 continues to rise until the elastic rope is pulled to the set displacement or broken, and the value of the displacement sensor 75 and the tension value at the time node are recorded, thereby realizing the tensile force detection of the elastic rope.

After the first electromagnet 913 and the second electromagnet 914 are energized, magnetic attraction or repulsion is generated, thereby controlling the plug-in rod 98 to be stably plugged into the first positioning hole 632 or the second positioning hole 910, and the bevel gears are located inside the protective cover 19. It should be noted that the plug-in rod 98 is initially plugged into the first positioning hole 632 under the action of the elastic part 911, and the lifting screw rod 74 and the support shaft 63 can also be provided with independent drive sources.

[0032] A detection method for a tension detection system of an equipment comprises the following steps: S1. During fatigue testing, according to the displacement or elastic stretch required to be tested, the threaded rod 65 is rotated to move the support column 67 on the adjustment block 66 to a position with a set distance from the center of the turntable 61. According to the weight required to be carried by the rigid rope or cable to be tested, the limit pin is inserted into the corresponding first limit hole 33 and second limit hole 34, and the load is set. When the fatigue tension of the elastic rope is detected, the limit pin is inserted into the first limit hole 33 and the second limit hole 34 at the bottom to fix the counterweight assembly 3 to the base plate 12.

[0033] S2. According to Figure 6 The two ends of the test rope or cable are fixed on the second lifting ring 35 and the third lifting ring 610 in a manner, and the third lifting ring 610 at different distances on the first lifting block 62 can be selected according to the length of the rope or cable. The output end of the screw lift 41 pushes the lifting frame 42 to rise, so that the rope or cable is tightened on the upper side of the two second rollers 5.

[0034] It should be noted that, when it is a fatigue test of a rigid rope or cable, the screw lifter 41 pushes the second roller 5 to rise until the connected counterweight 31 is lifted to a set height, so as to avoid collision between the working counterweight 31 and the non-working counterweight 31 during the reciprocating fatigue test; when it is detected as an elastic fatigue test of an elastic rope, the screw lifter 41 pushes the second roller 5 to rise until the pressure sensor under the second roller 5 reaches the set initial threshold value, at which time the elastic rope is in an initial tensioned state.

[0035] S3, a positive current is passed through the first electromagnet 913 and the second electromagnet 914, and the two generate magnetic attraction, so that the plug-in rod 98 is stably inserted into the first positioning hole 632; S4, the output shaft of the driving motor 91 drives the telescopic rod 96 to rotate, thereby driving the first fixed plate 97, the plug rod 98, the second fixed plate 631, the support shaft 63 and the turntable 61 to rotate, the turntable 61 drives the adjustment block 66 and the support column 67 to rotate circumferentially, and the support column 67 pushes the first lifting block 62 to make up and down reciprocating motion on the guide rail 16, thereby pulling the rope or cable to be tested to achieve fatigue detection. When the pressure of the pressure sensor disappears, the detection ends, and the number of turns recorded by the counter is the number of times the rope or cable is pulled; S5, tension test, fix the two ends of the rope or cable to be tested on the first hanging ring 18 and the fourth hanging ring 81 respectively, and pass the reverse current through the first electromagnet 913 and the second electromagnet 914 to generate repulsion, so that the plug-in rod 98 is inserted into the second positioning hole 910 on the second bevel gear 99. It should be noted that the power-on of the first electromagnet 913 and the second electromagnet 914 can include two processes, namely, a small current process and a large current process. The small current generates a small repulsion. When the driving motor 91 drives the first fixed disk 97 and the plug-in rod 98 to rotate, the plug-in rod 98 abuts against the second bevel gear 99 with a small push-out force, thereby keeping the plug-in rod 98 relative to the second bevel gear 99, so that the plug-in rod 98 can adjust its position with the second positioning hole 910, reducing the difficulty of plugging the plug-in rod 98. After the plug-in rod 98 is inserted into the second positioning hole 910, a large current is passed to generate a large repulsion, thereby ensuring the stability of the plug-in transmission of the plug-in rod 98; S6, the output shaft of the driving motor 91 drives the first fixed plate 97 and the second bevel gear 99 to rotate, and through the meshing transmission with the third bevel gear 912, drives the first bevel gear 95 and the lifting screw 74 to rotate, so that the second lifting block 73 and the tension meter 8 are lifted and lowered, and the rope or cable is pulled to perform tension detection; S7. When testing the elastic rope, first the second lifting block 73 is moved upward to make the value of the dynamometer 8 reach the first threshold value, and the value of the displacement sensor 75 is recorded. At this time, the elastic rope is in an initial tensioned state, and the second lifting block 73 continues to rise until the elastic rope is pulled to a set displacement or broken, and the value of the displacement sensor 75 and the tension value at this time node are recorded to realize the tensile force detection of the elastic rope.
