The outer side of 14 is threadedly connected to a moving block 16, and a support column 17 is welded to the end of the moving block 16, that is, one end of the moving block is threadedly sleeved on the screw rod 14, and the other end is welded and fixedly connected to the support column 17, and the support column 17 is slidably connected to the fixed block 13 to form a sliding structure with the fixed block 13. Specifically, the fixed grooves 12 are evenly spaced inside the adjusting rod 10, and the four fixed blocks 13 are symmetrically arranged about the center of the base 1, and a positioning block is also fixedly arranged on the top of the fixed block 13 corresponding to the rod portion of the turntable 15, and a limit pin for limiting the turntable is rotatably arranged in the positioning block.

[0032] In specific implementation, a pile driver is more common in construction projects and is a drilling and piling equipment. Due to the uneven ground in the construction area, it is difficult for the pile driver to be placed stably during use and it is easy to tilt. The fixed block 13 can be pulled in a direction away from the base 1. When the fixed block 13 moves, the adjusting rod 10 can be driven to move. When the adjusting rod 10 moves, the limit block 11 can be driven to move. When a fixing groove 12 on the adjusting rod 10 moves to a position just below the threaded knob 9, the threaded knob 9 can be tightened so that the bottom end of the threaded knob 9 can limit and fix the adjusting rod 10 through the fixing groove 12. At this time, the screw can be loosened first. The limit pin rotates the turntable 15 forward. When the turntable 15 rotates, it can drive the screw rod 14 to rotate. When the screw rod 14 rotates, it can drive the moving block 16 to slide downwardly through the thread. When the moving block 16 slides through the thread, it can drive the support column 17 to move downward. When the bottom end of the support column 17 moves to the ground, the support column 17 can support the inclined side of the base 1, so that the base 1 can be stably placed on the ground. At the same time, tighten the threaded limit pin under the turntable 15 so that the end of the threaded limit pin can squeeze the outer side of the screw rod 14, so that the turntable 15 is not easy to rotate, and the position supported by the support column 17 can be adjusted according to the actual situation on the ground.

[0033] See also Figure 1-Figure 4 It can be seen that the support column 17 can be used to provide auxiliary support for the base 1, so that the base 1 is not easy to tilt on the uneven ground, thereby avoiding the tilting of drilling and piling, and ensuring the stability of the pile driver during use.

[0034] Please continue reading Figure 1-Figure 4 It can be seen that the first rotating rod 18 is installed inside the fixed block 13 through a bearing, the first gear 19 is welded to the outside of the first rotating rod 18, the second rotating rod 20 is installed inside the fixed block 13 near the first gear 19 through a bearing, the second gear 21 is welded to the outside of the second rotating rod 20, and the sliding rod 22 is slidably connected inside the fixed block 13 near the second gear 21 (the sliding rod 22 and the screw rod 14 are respectively located on both sides of the support column 17), and the support column 17 is provided with a tooth groove 23 on the side opposite to the sliding rod 22 (the support column 17 is provided with a tooth groove 23 on the side away from the screw rod 14). A first tooth groove is formed, and the support column 17 is meshed and connected with the first gear 19 through the first tooth groove; a second tooth groove is formed on the side of the slide rod 22 opposite to the support column 17, and the slide rod 22 is meshed and connected with the second gear 21 through the second tooth groove), a threaded column 25 is threadedly connected to the bottom end of the slide rod 22, and an anti-slip seat 24 is connected to the bottom end of the threaded column 25; the first gear 19 and the second gear 21 have the same size, and the size of the tooth groove 23 matches the size of the tooth blocks on the first gear 19 and the second gear 21, and a meshing structure is formed between the first gear 19 and the second gear 21.

[0035] During specific implementation, the pile driver can drill holes and drive piles at designated locations in the construction area of ​​a building project. A conventional pile driver is placed on the ground via a universal wheel 2. During use of the pile driver, the driving motor 6 will generate a certain degree of vibration on the base 1 and the support frame 3, causing the pile driver to shake easily as a whole. Moreover, the pile driver is not stable enough because it is supported only by the universal wheel 2. When the turntable 15 is rotated forward, the screw rod 14 can be driven to rotate. When the screw rod 14 rotates, the moving block 16 can be driven to slide in a threaded manner toward the ground. When the moving block 16 slides in a threaded manner, the support column 17 can be driven to move. When the support column 17 moves, the tooth groove 23 inside the support column 17 can be engaged to drive the first gear 19 to rotate clockwise. When the first gear 19 rotates, it can drive the first rotating rod 18 to rotate, and while the first gear 19 rotates, it can engage and drive the second gear 21 to rotate counterclockwise. When the second gear 21 rotates, it can drive the second rotating rod 20 to rotate, and while the second gear 21 rotates, it can engage the tooth groove 23 inside the sliding rod 22 to drive the sliding rod 22 to move toward the ground. When the sliding rod 22 moves, it can drive the threaded column 25 and the anti-slip seat 24 to move. When the bottom of the anti-slip seat 24 moves to the ground, the anti-slip seat 24 and the sliding rod 22 can support the base 1, and when the anti-slip seat 24 is reversed, the threaded column 25 can be driven to slide out from the bottom end of the sliding rod 22. At this time, the worn anti-slip seat 24 can be replaced.

[0036] See also Figure 1-Figure 4 It can be seen that the anti-slip seat 24 can improve the contact area between the base 1 and the ground and the stability of the support, so that the base 1 and the support frame 3 are not prone to shaking during the use of the pile driver.

[0037] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 It can be seen that mounting frames 26 are welded to the upper surfaces of the front and rear sides of the base 1, and a docking block 27 is placed inside the mounting frame 26. The mounting frame 26 and the interior of the docking block 27 are threadedly connected with bolts 28 to fix the docking block 27 on the mounting frame 26, and each docking block 27 is connected to a clamping mechanism, which includes a connecting plate 29, which is connected to the end of the docking block 27, and the internal thread of the connecting plate 29 is penetrated and connected with a threaded rod 30, and both ends of the connecting plate 29 are threadedly connected to the threaded rod 30, and the end of the threaded rod 30 is welded with a rotating block 31, and the outer side of each rotating block 31 is rotatably connected to a mounting block 32 through a bearing, and the end of the mounting block 32 is connected to a clamping block 33, and the shape of the clamping block 33 is trapezoidal.

[0038] During specific implementation, after the pile driver drills a hole in the ground according to the requirements of the construction, the pile column 7 needs to be driven into the drilled hole. During the process of piling, once the pile column 7 is tilted due to the placement of the pile column 7, the pile driving will be tilted, thereby affecting the effect of piling. The docking block 27 can be placed inside the mounting frame 26 first, and the mounting frame 26 and the docking block 27 can be fixed together with bolts 28, and then the threaded rod 30 can be rotated forward. When the threaded rod 30 rotates forward, it can slide in the direction of the pile column 7 through the connecting plate 29. When the threaded rod 30 rotates, it can drive the rotating block 31 to rotate inside the mounting block 32. At the same time, when the threaded rod 30 slides, it can push the mounting block 32. When the mounting block 32 moves, it can drive the clamping block 33 to move.

[0039] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 It can be seen that when one side of the four clamping blocks 33 is moved to the outer surface of the pile column 7, the four clamping blocks 33 can limit and guide the pile column 7, so that the pile column 7 is not easy to tilt during the placement process, thereby avoiding the occurrence of pile driving tilt. At the same time, the positions of the four clamping blocks 33 can be adjusted by rotating the threaded rod 30, so that the four clamping blocks 33 can limit and guide the pile columns 7 of different diameters, so that the pile driver can perform pile driving construction operations according to the pile columns 7 of different diameters.

[0040] In summary, when the pile driver that can be adjusted to adapt to the terrain is used, the movable plate 5 and the drive motor 6 can be driven to move by rotating the chain winch 4. When the drive motor 6 is running, drilling and pile driving operations can be performed. The portable pile driver is a prior art and will not be described in detail here. The support column 17 can support the inclined side of the base 1 so that the base 1 can be stably placed on the ground, and the position supported by the support column 17 can be adjusted according to the actual situation of the ground. The support column 17 can be used to provide auxiliary support for the base 1, so that the base 1 is not easy to tilt on an uneven ground, thereby avoiding the tilting of drilling and piling, and ensuring the stability of the pile driver during use. The anti-skid seat 24 and the slide rod 22 can support the base 1, and the anti-skid seat 24 can be reversed. When the pile driver is in use, the base 1 and the support frame 3 are not easy to shake. When one side of the four clamping blocks 33 moves to the outer surface of the pile column 7, the four clamping blocks 33 can limit and guide the pile column 7, so that the pile column 7 is not easy to tilt during placement, thereby avoiding the occurrence of pile driving tilt. At the same time, the positions of the four clamping blocks 33 can be adjusted by rotating the threaded rod 30, so that the four clamping blocks 33 can limit and guide the pile columns 7 of different diameters, so that the pile driver can perform pile driving construction operations according to the pile columns 7 of different diameters.
