[0026] Embodiment 1: Please refer to Figures 1-5 , a pile driving device with a positioning structure, including a support frame 1. An elevating plate 2 is arranged inside the support frame 1.

[0028] The piston rod 7 penetrates through the top end of the support frame 1 and extends into the inside of the support frame 1 and is fixedly connected to the connecting frame 8. The reinforcing plate 24 is fixedly connected to the elevating plate 2;

[0029] The center line of the connecting frame 8 and the center line of the elevating plate 2 are in the same vertical plane. The center line of the piston rod 7 and the center line of the connecting frame 8 are in the same vertical plane;

[0030] Specifically, as shown in Figure 1 and Figure 4 , when driving a pile, after installing the device at the pile driving position, start the driving motor 5 to drive the rotating shaft 22 to rotate. Then start the hydraulic cylinder 6 to push the connecting frame 8 to descend through the piston rod 7. The connecting frame 8 then drives the rotating shaft 22 and the first conical head 15 at the bottom through the elevating plate 2 to descend. In this way, while the rotating shaft 22 rotates and continuously descends, it can cooperate with the spiral blade 14 and the first conical head 15 to complete drilling, thereby automatically completing the pile driving project, realizing that the pile driving mechanism can be automatically driven to descend to complete pile driving drilling.

[0031] Embodiment 2: A set of fixed columns 3 are respectively fixedly connected to both sides of the top end inside the support frame 1. A set of limit sleeves 9 are respectively fixedly connected to both sides of the bottom of the elevating plate 2. A fixed sleeve 16 is fixedly connected to the top end of the bottom plate 13;

[0032] The fixed column 3 passes through the limit sleeve 9 and is fixedly connected to the bottom plate 13, and the limit sleeve 9 is slidably connected to the fixed column 3;

[0033] The fixed sleeve 16 is movably connected to the spiral blade 14, and the central axis of the fixed sleeve 16 and the central axis of the bottom plate 13 are on the same vertical plane;

[0034] Specifically, as Figure 1 and Figure 2 shown, when driving a pile, the limit sleeve 9 at the bottom end of the lifting plate 2 fits on the outside of the fixed column 3, which can effectively limit the lifting plate 2, improve the stability of the lifting plate 2 during lifting and during the pile driving process, thereby improving the stability of the pile driving mechanism during operation. And the fixed sleeve 16 at the top end of the bottom plate 13 fits on the outside of the spiral blade 14, which can limit the rotating shaft 22 through the spiral blade 14 to further improve the stability of the pile driving mechanism during operation, achieving the effect of effectively improving the stability of the pile driving mechanism.

A threaded rod 11 is movably connected inside the threaded sleeve 20. A rotating wheel 10 is fixedly connected to the top end of the threaded rod 11. A hand wheel 21 is fixedly connected to the top end of the rotating wheel 10. The threaded rod 11 extends into the fixed cylinder 12 and is fixedly connected to a connecting disk 19. A positioning insertion rod 18 is fixedly connected to the bottom end of the connecting disk 19. A second conical head 17 is fixedly connected to the bottom end of the positioning insertion rod 18. On both sides outside the bottom plate (13), movable support plates (26) are provided. Connecting rods (27) are fixedly connected to the bottoms of both ends inside the movable support plates (26). The connecting rods (27) extend into the fixed cylinder (12) and are fixedly connected to positioning sleeves (28);

[0036] The central axis of the threaded rod 11 and the central axis of the rotating wheel 10 are on the same vertical plane, and the connecting disk 19 is movably connected to the fixed cylinder 12;

[0037] Specifically, as Figure 1 , Figure 3 and Figure 5 shown, before driving a pile, place the device at the designated pile driving position, flip the movable support plates 26 on both sides to make them fit the ground, and then rotate the hand wheel 21 to drive the threaded rod 11 to rotate through the rotating wheel 10. While the threaded rod 11 rotates inside the threaded sleeve 20, it pushes the connecting disk 19 at the bottom to descend. The connecting disk 19 drives the positioning insertion rod 18 to descend and quickly insert into the foundation soil layer through the second conical head 17, thereby positioning the entire device through the positioning insertion rod 18. At the same time, the positioning insertion rod 18 will insert into the positioning sleeve 28 and position the movable support plate 26 through the connecting rod 27. The movable support plate 26 can support the device main body to improve the stability of the device, achieving the effect of conveniently positioning the device.

[0038] Working principle: When the utility model is in use, before pile driving, the device is placed at the designated pile driving position, and the movable support plates 26 on both sides are flipped to fit the ground. Then, the hand wheel 21 is rotated to drive the threaded rod 11 to rotate through the runner 10. While the threaded rod 11 rotates inside the threaded sleeve 20, it pushes the connecting plate 19 at the bottom to descend. The connecting plate 19 drives the positioning insertion rod 18 to descend and quickly insert into the foundation soil layer through the second cone head 17, so as to position the whole device through the positioning insertion rod 18. At the same time, the positioning insertion rod 18 will insert into the positioning sleeve 28 and position the movable support plate 26 through the connecting rod 27. The movable support plate 26 can support the main body of the device to improve the stability of the device. When pile driving, after the device is installed at the pile driving position, the driving motor 5 is started to drive the rotating shaft 22 to rotate. Then, the hydraulic cylinder 6 is started to push the connecting frame 8 to descend through the piston rod 7. The connecting frame 8 then drives the rotating shaft 22 and the first cone head 15 at the bottom to descend through the lifting plate 2. In this way, while the rotating shaft 22 rotates and descends continuously, it can cooperate with the spiral blade 14 and the first cone head 15 to complete drilling, thus automatically completing the pile driving project. When pile driving, the limiting sleeve 9 at the bottom end of the lifting plate 2 fits on the outside of the fixed column 3, which can effectively limit the lifting plate 2 and improve the stability of the lifting plate 2 during lifting and during pile driving, so as to improve the stability of the pile driving mechanism during operation. Moreover, the fixed sleeve 16 at the top end of the bottom plate 13 fits on the outside of the spiral blade 14, which can limit the rotating shaft 22 through the spiral blade 14 to further improve the stability of the pile driving mechanism during operation.
