The two groups of clamping plates 7 are respectively slidably connected in the clamping grooves 71 on both sides, and the side of the clamping plate 7 away from the positioning socket 41 is fixedly connected with a pull rod 72. The top of the positioning box 4 is fixedly connected with a mounting plate 73, and a threaded rod 74 is rotatably connected to the mounting plate 73. The upper ends of the two groups of pull rods 72 are fixedly connected with pull plates 75, and the pull plates 75 on both sides are threadedly sleeved on the threaded rod 74, and the thread directions on both sides of the threaded rod 74 are opposite.

[0038] Through the arrangement of the above structure, the cable to be tested is passed through the threading plate 2, the positioning box 4, the thermal insulation cover 6, the positioning box 4 on the other side and the threading plate 2 in sequence, and it is ensured that the cable is located between each group of two twisted columns 31. Then the cable is straightened, and the threaded rods 74 on both sides are rotated so that the pulling plate 75 slides along the threaded rods 74, thereby driving the clamping plates 7 on both sides to slide toward the side close to the cable, and finally fixing the cable in the positioning box 4, ensuring the stability of the cable during testing.

[0039] Reference Figure 1 、 Figure 2, wherein the driving part includes a reciprocating screw 5, and positioning plates 51 are fixedly connected to both sides of the side wall of the detection platform 1.

[0040] By setting the above structure, after the cable is fixed, the scale value of the positioning box 4 on the scale guide rail 42 is recorded, and then the driving motor 52 is turned on to drive the reciprocating screw rod 5 to rotate, so that the moving seat 53 slides back and forth along the reciprocating screw rod 5. At this time, the meshing relationship between the driven teeth 55 and the driving rack 54 is used to make the kink disk 3 rotate back and forth, and each time it bends, the cable will be pulled toward the kink disk 3, so that the positioning box 4 slides toward the kink disk 3 along the scale guide rail 42 and stretches the first spring 43. This reciprocating process realizes the reciprocating bending and stretching of the cable. After multiple reciprocating movements, the bending part of the cable is observed.

At this time, the repulsive effect of the magnetic plates 83 and the piston plate 81 will cause the piston plate 81 to slide toward the side of the compressed second spring 78, thereby compressing the gas in the cavity of the piston box 8 and opening the one-way valve in the inflation tube 84, so that the compressed gas enters the clamping groove 71 along the inflation tube 84, thereby pushing the clamping plate 77 to approach the cable, achieving further clamping of the cable during the bending process, effectively ensuring the stability of the cable during the detection process, and improving the detection efficiency.

Then the cable is straightened and the threaded rods 74 on both sides are rotated in sequence, so that the pulling plate 75 slides along the threaded rods 74, thereby driving the clamping plates 7 on both sides to slide toward the side close to the cable, and finally fixing the cable in the positioning box 4, ensuring the stability of the cable during detection, and adjusting the first spring 43 to a tensioned state, and recording the scale value of the positioning box 4 on the scale guide rail 42 at this time; then the driving motor 52 is turned on to drive the reciprocating screw rod 5 to rotate, so that the moving seat 53 slides back and forth along the reciprocating screw rod 5, and the meshing relationship between the driven teeth 55 and the driving rack 54 is used to make the kinked disk 3 rotate back and forth, and at each During the first bending, the cable will be pulled toward the kink disk 3, causing the positioning box 4 to slide toward the kink disk 3 along the scale guide 42, and stretching the first spring 43, and so on, to realize the reciprocating bending and stretching of the cable. After multiple reciprocating movements, the bending part of the cable is observed to determine the flexibility and bending performance of the cable. At the same time, the scale value of the positioning box 4 on the scale guide 42 is recorded again and compared with the original record to determine the tensile and rebound properties of the cable. In summary, the flexibility, bending performance, tensile performance and rebound performance of the cable are detected simultaneously, which reduces the detection steps and effectively improves the detection efficiency. Subsequently, the temperature of the detection environment in the heat preservation cover 6 can be changed by the thermostat 61 to obtain the corresponding performance of the cable under different temperature environments, thereby effectively improving the representativeness of the detection results.

[0046] In addition, during the reciprocating rotation of the kinking disk 3, the magnetic plates 83 located on both sides of its bottom will alternately move to the top of the piston box 8. At this time, the repulsive effect between the magnetic plates 83 and the piston plate 81 will cause the piston plate 81 to slide toward the side of the compressed second spring 78, thereby compressing the gas in the cavity of the piston box 8 and opening the one-way valve in the inflation tube 84, so that the compressed gas enters the clamping groove 71 along the inflation tube 84, thereby pushing the clamping plate 77 closer to the cable, achieving further clamping of the cable during the bending process, effectively ensuring the stability of the cable during the detection process, and thus improving the detection accuracy; When the magnetic plate 83 and the piston plate 81 are separated from the repulsive area, the piston plate 81 will reset upward under the rebound action of the second spring 78, thereby generating suction in the cavity of the piston box 8 and opening the one-way valve in the suction pipe 85, so that the gas in the threading cavity of the kinked column 31 can enter the piston box 8 along the suction pipe 85 and through the filter box 86, thereby cleaning the impurities and dust attached to the surface of the cable in the bending area, avoiding the influence of additional friction, ensuring the detection accuracy, and at the same time cleaning the debris caused by cable wear for subsequent observation and detection, thereby improving the detection efficiency and reducing the detection error.
