Its main task is to firmly press precast piles, such as concrete piles and steel piles, into the foundation soil. Based on different working principles, it can be further divided into static pile drivers and hammer pile drivers. When carrying out special structure construction in urban core areas, static pile drivers perfectly meet the environmental protection requirements of low noise and low vibration, while ensuring the accuracy of pile foundation forming, thus providing a solid foundation for tall buildings and precision scientific research facilities.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a high-efficiency hydraulic drive device for a pile driver, comprising a workbench 1, a support frame 2 fixedly connected inside the workbench 1, a base 3 fixedly connected to the lower surface of the support frame 2, a transmission platform 4 slidably connected to the outer wall of the support frame 2, a fixed frame 5 slidably connected to the inner wall of the transmission platform 4, a hollow block 6 fixedly connected to the outer wall of the fixed frame 5, a connecting rod 7 rotatably connected inside the hollow block 6, one end of a spiral spring 8 fixedly connected to the outer wall of the connecting rod 7, the other end of the spiral spring 8 fixedly connected to the inner wall of the hollow block 6, and a transmission mechanism fixedly connected to the outer wall of the connecting rod 7. A short rod 10 is fixedly connected inside the transmission plate 9. An L-shaped plate 11 is rotatably connected to the outer wall of the short rod 10. A convex block 12 is rotatably connected to the outer wall of the L-shaped plate 11. Slider blocks 13 are fixedly connected to both outer walls of the convex block 12. The outer wall of the convex block 12 is slidably connected to the inner wall of the transmission table 4. A drive assembly is provided on the upper surface of the worktable 1. The drive assembly is used to drive the transmission table 4. The drive assembly includes a hydraulic cylinder 14. The lower surface of the hydraulic cylinder 14 is fixedly connected to the upper surface of the worktable 1. The output end of the hydraulic cylinder 14 passes through the interior of the worktable 1 and is fixedly connected to the upper surface of the transmission table 4.

[0025] Specifically, the base 3 supports the workbench 1 via the support frame 2, and the support frame 2 restricts the movement of the transmission table 4. Hydraulic cylinders 14 are fixed around the workbench 1 to improve the balance of the pile driving force. At the same time, the pressure ratio in each direction can be adjusted as needed, either concentrating the force on one side to break through the local hard layer or pressing down evenly to penetrate the dense layer, making the pile more efficient in penetrating complex strata and reducing the phenomenon of pile jamming and stagnation. The inner wall of the fixing frame 5 is provided with anti-slip stripes to enhance the friction between the fixing frame 5 and the pile, thereby driving the pile to move. The interior of the hollow block 6 supports the rotation of the connecting rod 7. The transmission plate 9 and the short rod 10 transmit power to the L-shaped plate 11 via the connecting rod 7, thereby driving the convex block 12 to move inside the hollow block 6. The spiral spring 8 limits the movement between the convex block 12 and the transmission table 4, thus providing support.

[0026] Reference Figure 3 The outer wall of the hollow block 6 is slidably connected to the inner wall of the transmission table 4, the middle outer wall of the convex block 12 is slidably connected to the interior of the hollow block 6, and the outer wall of the slider 13 is slidably connected to the inner wall of the hollow block 6.

[0027] Specifically, the inner wall of the transmission table 4 slides against the hollow block 6 to achieve the positioning effect, the interior of the hollow block 6 slides against the convex block 12 to achieve the offset restriction effect, and the slider 13 slides on the inner wall of the hollow block 6 to achieve the auxiliary and further limiting effect on the sliding of the convex block 12.

[0028] Reference Figure 4 The base 3 has a sliding rod 15 inside, and a handle 16 is fixedly connected to the outer wall of the sliding rod 15; a fixing block 17 is fixedly connected to the right outer wall of the sliding rod 15; a spring body 19 is fixedly connected to the left outer wall of the fixing block 17, and the left outer wall of the spring body 19 is fixedly connected to the inner wall of the base 3; a ball bearing 18 is provided on the inner wall of the fixing block 17.

[0029] Specifically, the sliding of the base 3 onto the slide bar 15 achieves the effect of offset limitation, the handle 16 facilitates operation of the slide bar 15, the slide bar 15 achieves the effect of fixing the fixed block 17, the inner wall of the fixed block 17 is provided with multiple balls 18, and the balls 18 rotate freely on the inner wall of the fixed block 17. Under the elastic force of the spring body 19, the balls 18 are used to assist the movement of the precast pile, and at the same time improve the stability of the movement of the precast pile.

[0030] Reference Figure 3 The L-shaped plate 11 is located on the upper side of the transmission plate 9, and the spiral spring 8 is located on the lower side of the transmission plate 9.

[0031] Specifically, the L-shaped plate 11 and the spiral spring 8 are spaced apart from the transmission plate 9 to prevent motion interference between the spiral spring 8 and the L-shaped plate 11 when the transmission plate 9 drives the L-shaped plate 11 and the spiral spring 8.

[0032] Working principle: When using this device, the precast pile is placed from top to bottom inside the workbench 1 and the fixed frame 5. The fixed frame 5 fixes the middle of the precast pile. The hydraulic cylinder 14 is activated to push the transmission table 4 and the fixed frame 5 downward, thereby pushing the precast pile into the foundation. The support frame 2 limits the movement of the transmission table 4. At the same time, the handle 16 pulls the slide rod 15 to slide inside the base 3, driving the fixed block 17 to move. This causes the ball bearings 18 on the inner wall of the fixed block 17 to contact the precast pile. Under the action of the spring body 19, the fixed block 17 and the ball bearings 18 are pushed into close contact with the precast pile, thereby improving the pressing of the precast pile. To ensure the stability of the foundation, when the fixing frame 5 needs to be replaced, rotating the connecting rod 7 drives the transmission plate 9 to rotate, causing the spiral spring 8 to tighten. The transmission plate 9 and the short rod 10 drive the L-shaped plate 11 to move towards the connecting rod 7, thereby causing the convex block 12 to slide towards the center of the hollow block 6. The slider 13 limits the sliding of the convex block 12. The convex block 12 slides out of the inner wall of the transmission table 4 and is no longer limited, achieving the effect of quickly installing and disassembling the fixing frame 5. During use, this device not only allows for quick installation and disassembly of the fixing frame 5, reducing maintenance costs, but also has the effect of assisting in positioning the precast piles for pressing into the foundation.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
