[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, this embodiment provides a clamping device for the tensile test of cement poles, including a mounting plate 1. On both sides of the lower surface of the mounting plate 1, A mounting seats 2 are welded. The lower surface of the A mounting seats 2 is installed with A hydraulic cylinders 3 through bolts. On both sides of the surface of the mounting plate 1, chutes 4 are provided. Inside the chutes 4, sliding frames 5 are slidably connected. The lower surface of the sliding frames 5 is welded with B mounting seats 6.

[0023] The lower surface of the B mounting seats 6 is fixedly installed with B hydraulic cylinders 7 through bolts. The output ends of the A hydraulic cylinders 3 and the B hydraulic cylinders 7 are both fixedly installed with collar rings 9 through fastening bolts 8. On one side of the collar rings 9, arc-shaped clamping rings 10 are welded. Inside the walls of the arc-shaped clamping rings 10, rubber anti-slip pads 11 are fixedly installed.

[0024] The A hydraulic cylinders 3 are fixed to the bottom of the mounting plate 1 through the A mounting seats 2. By starting the A hydraulic cylinders 3, the arc-shaped clamping rings 10 are driven to move inward to clamp the cement poles, thereby realizing the relative fixation of the device and the cement poles. The B hydraulic cylinders 7 slide on the mounting plate 1 through the sliding frames 5 to clamp the cement poles and make their positions relatively fixed. During subsequent use, pulling is performed at the two clamping positions to realize the tensile test of the cement poles.

[0027] The cone head 16 at the bottom of the screw rod 14 is used to fix the screw rod 14. After the fixing is completed, the height of the mounting plate 1 is adjusted by adjusting the positions of the two positioning bolts 15 on the screw rod 14, so as to facilitate the horizontal clamping of the cement pole, reduce the need for large equipment, facilitate the operation of personnel, and greatly improve the fixing efficiency of personnel for the cement pole.

[0028] Specifically, when the clamping device for the tensile test of the cement pole works / is in use: during use, the mounting plate 1 is positioned and fixed by the screw rod 14 on the device. Subsequently, the positioning bolt 15 is rotated to adjust the height of the mounting plate 1, so that the position of the arc-shaped clamping ring 10 can be flush with the cement pole. Then, the A hydraulic cylinder 3 and the B hydraulic cylinder 7 are started to drive each arc-shaped clamping ring 10 to clamp the cement pole, so that the A hydraulic cylinder 3 and the B hydraulic cylinder 7 clamp the two places of the cement pole through the arc-shaped clamping ring 10. Subsequently, a tensile device is connected to the pull ring 12, and under the action of the tensile device pulling the B mounting seat 6, the tensile test effect of the cement pole is achieved.
