[0025] Specifically, two bases 1 are used to support various parts. A fixing frame 2 is fixed on the top of the base 1 for fixing a supporting frame 3. The supporting frame 3 is used to provide rotation for a telescopic cylinder 4. The other end of the telescopic cylinder 4 rotates on a supporting frame 2 5 and is connected to an extension hand 7 through a fixing frame 2 6. The fixing hand 9 is connected through a sliding rod 8. The height of the extension hand 7 can be adjusted by controlling the telescopic cylinder 4, so that the longer pile foundation column 26 can be fixed through the fixed hand 9.

[0026] Reference Figure 4 The mobile component includes a grounding frame 14, which is fixedly connected to the bottom of the base 1. The grounding frame 14 is rotatably connected to a bidirectional threaded rod 15 inside the grounding frame 14. The outer periphery of the bidirectional threaded rod 15 is threadedly connected to two moving blocks 16. The bottoms of the two moving blocks 16 are both rotatably connected to connecting rods 17. The other ends of the two connecting rods 17 are fixedly connected to a rotating frame 18. The two rotating frames 18 are rotatably connected to support rods 19 inside. Both ends of the two support rods 19 are rotatably connected to wheels 20. The tops of the two support rods 19 are fixedly connected to telescopic rods 24. The tops of the multiple telescopic rods 24 are fixedly connected to the bottom of the base 1. A driving component is provided at the rear end of the grounding frame 14. The driving component includes a fixed block 21, which is fixedly connected to the rear end of the base 1. The top of the fixed block 21 is fixedly connected to a motor 22. The output end of the motor 22 is fixedly connected to the rear end of the bidirectional threaded rod 15. The middle part of the bidirectional threaded rod 15 is rotatably connected to a limiting frame 23. The top of the limiting frame 23 is fixedly connected to the bottom of the base 1. The bottom of the grounding frame 14 is fixedly connected to a grounding hole 25.

[0027] Specifically, the grounding frame 14 is fixed to the bottom of the base 1 and is used to support various parts of the moving assembly. A bidirectional threaded rod 15 rotates inside the grounding frame 14. When it rotates, the two moving blocks 16 move in opposite directions. A connecting rod 17 rotates at the bottom of the moving block 16 to pull the rotating frame 18. A support rod 19 rotates inside the rotating frame 18 to cooperate with a telescopic rod 24 fixed to the bottom of the base 1 to extend or retract the wheel 20. A fixed block 21 is fixed on the grounding frame 14 and is used to support a motor 22. The motor 22 is used to rotate the bidirectional threaded rod 15. A limit frame 23 rotates in the middle of the bidirectional threaded rod 15. The limit frame 23 is fixed to the bottom of the base 1 to prevent the two moving blocks 16 from colliding with each other. The grounding frame 14 is fixed with a grounding hole 25 for inserting screws to fix it to the ground.

[0028] Reference Figure 1-3 The connecting assembly includes a worm 10, which is rotatably connected to the inside of the right base 1. The bottom of the worm 10 is meshed with two worm wheels 11. The two worm wheels 11 are fixedly connected with one-way threaded rods 12. The two one-way threaded rods 12 are rotatably connected to the inside of the right base 1. A handle 13 is fixedly connected to the front end of the worm 10.

[0029] Specifically, a worm 10 rotates inside the base 1 to rotate two worm wheels 11. The worm wheels 11 are used to drive a one-way threaded rod 12. The one-way threaded rod 12 rotates inside the base 1 and cooperates with another base 1 through the one-way threaded rod 12 to clamp the pile foundation column 26. The worm 10 fixes a handle 13 to help the operator to better rotate the worm 10.

[0030] Working principle: first place the two bases 1 on both sides of the pile foundation column 26 respectively, align the one-way threaded rod 12 with the matching position, turn the handle 13 to drive the worm 10 to rotate, and when the worm 10 rotates, it drives the worm wheel 11 to rotate, and when the worm wheel 11 rotates, it drives the one-way threaded rod 12 to rotate. When the one-way threaded rod 12 rotates, the two bases 1 are brought close to fix the pile foundation column 26. When the pile foundation column 26 is higher, start the two telescopic cylinders 4, and the telescopic cylinders 4 drive the extension hand 7 to move on the fixed hand 9 through the sliding rod 8, and the extension hand 7 can move upward to fix the higher pile foundation column 26.

[0031] When the wheel 20 needs to be folded up and fixed to the ground, the starting motor 22 drives the bidirectional threaded rod 15 to rotate. When the bidirectional threaded rod 15 rotates, it drives the two moving blocks 16 to move toward the limit frame 23. When the moving block 16 moves, the support rod 19 is pulled by the connecting rod 17. Because the support rod 19 is fixed under the base 1 by the telescopic rod 24, the support rod 19 can be retracted into the ground frame 14, and the wheel 20 can be retracted.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
