A bolt 8 is threadedly connected to the mouth, a positioning sleeve 9 is arranged on the guide rod 4, a rotatable clamping rod 10 is symmetrically arranged on the upper surface of the movable plate 5, the lower ends of the two clamping rods 10 are connected by a first spring 11, a clamping groove 12 is arranged on the upper end side of the clamping rod 10, a through groove 13 is arranged on the upper end of the clamping rod 10, a fixing platform 14 is arranged on the base 1, the fixing platform 14 passes through the mounting plate 2, an electric telescopic rod 15 is arranged on the upper surface of the fixing platform 14, an extension rod 16 is arranged at the output end of the electric telescopic rod 15, a force sensor 17 is arranged at the lower end of the extension rod 16, and a clamping block 18 is arranged at the lower end of the force sensor 17.

[0019] The lower surface of the base 1 is provided with an anti-skid pad, which can increase the friction between the device and the workbench when the device is placed on the workbench, and prevent the base 1 from sliding when the mounting plate 2 on the base 1 is rotated.

[0020] The fixing part is used to clamp the auxiliary material belt 19. The fixing parts on the fixed plate 3 and the movable plate 5 clamp one end of the auxiliary material belt 19 respectively. At the same time, the auxiliary material belt 19 needs to be trimmed to the same length. When clamping one end of the auxiliary material belt 19 by the fixing part, one end of the auxiliary material belt 19 is passed through the annular notch on the vertical plate 6, and one end of the auxiliary material belt 19 is made to contact the bottom surface of the vertical plate 6. At this time, the auxiliary material belt 19 is located between the vertical plate 6 and the annular plate 7. At this time, by rotating the bolt 8, the bolt 8 is continuously screwed into the annular notch of the vertical plate 6, so that the annular plate 7 and the vertical plate 6 can cooperate to squeeze the auxiliary material belt 19 in the vertical plate 6, thereby clamping and fixing one end of the auxiliary material belt 19. At the same time, an elastic pad 20 is also provided inside the annular plate 7. The elastic pad 20 is located outside the annular notch at the upper end of the vertical plate 6. The elastic pad 20 is used to squeeze the annular plate 7 in a direction away from the inner side of the vertical plate 6, so as to facilitate passing one end of the auxiliary material belt 19 through the annular notch on the vertical plate 6.

[0021] A support tube 26 is provided on the fixed platform 14, and the electric telescopic rod 15 is located inside the support tube 26. The support tube 26 can improve the stability of the electric telescopic rod 15. The output end of the electric telescopic rod 15 drives the force sensor 17 and the card block 18 to move in the vertical direction through the extension rod 16. When the card block 18 moves downward, the lower end of the card block 18 enters between the two card rods 10, and is mutually engaged with the card groove 12 on the card rod 10 through the upper surface of the card block 18, and through the first spring 11, the card block 18 can be stably connected to the card rods 10 on both sides. When the card rod 10 is connected to the card block 18, the card rod 10 can be driven to move upward by controlling the output end of the electric telescopic rod 15 to move upward, thereby driving the movable plate 5 along The guide rod 4 moves upward, so that the auxiliary material belt 19 between the movable plate 5 and the fixed plate 3 is stretched, and the data is transmitted to the computer through the force sensor 17 to facilitate the detection of the tensile performance of the auxiliary material belt 19. When the block 18 and the clamping rod 10 are clamped with each other, the positioning sleeve 9 can prevent the movable plate 5 from moving downward along the guide rod 4, thereby facilitating the clamping of the block 18 and the clamping rod 10; when it is necessary to replace a different auxiliary material belt 19 for tensile performance testing, it is only necessary to restore the electric telescopic rod 15 to its original state, and then squeeze the first spring 11 through the two clamping rods 10, and then control the block 18 to move upward. At this time, the clamping of the block 18 and the clamping rod 10 is completed, and then the mounting plate 2 is rotated to move the next auxiliary material belt 19 to the bottom of the block 18.

[0022] Furthermore, a mounting groove is provided inside the base 1, a second spring 21 is arranged inside the mounting groove, a positioning ball 22 is arranged on the upper end of the second spring 21, and a plurality of arc grooves are provided on the lower surface of the mounting plate 2, the number of the arc grooves is equal to the number of clamping components, and the arc grooves are semicircular, and when different auxiliary material belts 19 are moved to the bottom of the clamping block 18, by rotating the mounting plate 2, when the arc groove on the mounting plate 2 and the mounting groove on the base 1 are docked with each other, under the action of the elastic force of the second spring 21, the positioning ball 22 is pushed into the arc groove on the lower surface of the mounting plate 2, thereby realizing the function of positioning the mounting plate 2, when the positioning ball 22 enters the arc groove, it represents that one of the auxiliary material belts 19 is located directly below the clamping block 18, and at this time, the clamping block 18 is controlled to move downward, so that it can form a clamping connection with the clamping rod 10.

[0023] Furthermore, a control rod 23 is provided on one side of the fixing plate 3 , and the mounting plate 2 can be rotated conveniently by the control rod 23 .

[0024] Furthermore, the positioning sleeves 9 on two adjacent groups of clamping assemblies are connected by a surrounding plate 24. The surrounding plate 24 can improve the stability of the guide rod 4 and prevent the guide rod 4 from deflecting and affecting the cooperation with the clamping block 18 and the clamping rod 10.

[0025] Furthermore, a stopper 25 is provided at the upper end of the guide rod 4 , and the stopper 25 can prevent the movable plate 5 from escaping from the guide rod 4 .

[0026] Working principle: When the tensile performance test of the auxiliary material belt 19 used on the cable is carried out, the auxiliary material belt 19 is first installed on all the clamping components. After the auxiliary material belt 19 is installed, the output end of the electric telescopic rod 15 is controlled to move downward so that the clamping block 18 and the clamping rod 10 are clamped together, and then the clamping rod 10 is controlled to move upward to drive the movable plate 5 to move upward, so as to test the tensile performance of the auxiliary material belt 19. After completing the test of the auxiliary material belt 19, the two ends of the clamping rod 10 can be directly pressed to compress the first spring 11 located between the two clamping rods 10, so that the clamping block 18 is separated from the two clamping rods 10, and then the mounting plate 2 is rotated to move the adjacent auxiliary material belt 19 to the bottom of the clamping block 18, and the tensile performance test of the auxiliary material belt 19 is carried out.

[0027] The device can install all the auxiliary material belts 19 on the testing device at one time. When the tensile performance of the auxiliary material belt 19 begins to be tested, the auxiliary material belt 19 that has not been tested can be quickly moved to the bottom of the block 18 by controlling the rotation of the mounting plate 2. The tensile performance of the auxiliary material belt 19 can be tested by controlling the extension and retraction of the electric telescopic rod 15, thereby reducing the test interval, improving the fluency of the test, and achieving good use effect.
