In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0026] Embodiment 1

[0027] Please refer to Figures 1-4, A municipal construction pile driver, including a vibration box 1, in front of which a motor 3 is installed through a first mounting frame 2; Rotating rollers 4 symmetrically distributed left and right are rotatably arranged in the vibration box 1, and one of the rotating rollers 4 is connected to the output of the motor 3 to drive its rotation; Different numbers of weight blocks 5 are respectively assembled on the two rotating rollers 4. Two weight blocks 5 are assembled on the left rotating roller 4, while only one weight block 5 is on the right rotating roller 4. When the two rotating rollers 4 rotate, vibration effects are generated by the mutual collision of the three weight blocks 5; A gear set 6 is jointly arranged at the rear ends of the two rotating rollers 4, and the function of the gear set 6 is to synchronously adjust the rotation speeds of the two rotating rollers 4 to ensure the stability of the vibration effect; A protective fence 28 is arranged at the rear side of the vibration box 1 to protect the gear set 6; First fixing frames 7 are arranged around the vibration box 1; A limiting frame 8 is slidably arranged jointly by two adjacent front and rear first fixing frames 7; An elastic member 9 is sleeved on the limiting frame 8, and the two ends of the elastic member 9 are respectively connected to the limiting frame 8 and the first fixing frame 7. The elastic member 9 stabilizes the vibration box 1 to ensure that the vibration box 1 remains in the center position during operation and reduces lateral swing; A lifting ring 10 is arranged at the top of the limiting frame 8, and the arrangement of the lifting ring 10 facilitates the connection between the pile driver and the equipment for hanging; A sliding frame 11 is fixedly connected to the limiting frame 8, and a support rod 12 for providing additional support to the pile driver is slidably arranged on the sliding frame 11 to enhance its stability; A support seat 13 is arranged at the lower end of the support rod 12; Support plates 14 symmetrically distributed front and rear are slidably arranged on the support seat 13, and the support plates 14 can expand outwards to expand the support area of the support seat 13 and further improve the overall stability of the pile driver.

[0028] First, connect the pile driver with a crane using the lifting ring 10. Then, the crane lifts the pile driver to the predetermined working height to prepare for pile driving operations. Once at the designated position, the operator adjusts the support rod 12 so that it touches the ground, providing stable support for the pile driver to prevent it from shaking due to external forces or vibrations during pile driving, ensuring the safety and efficiency of the operation. After preparation, start the motor 3. The power of the motor 3 is transmitted through the gear set 6 to drive the two rotating rollers 4 to rotate in opposite directions, and collisions occur between the weight blocks 5, forming a strong vibration effect. This vibration energy is transmitted downward, pushing the pile head towards the soil and forcing the pile to gradually penetrate into the soil, finally completing the pile driving operation.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, please refer to Figure 5, a second fixing frame 15 is fixedly connected to the upper part of the limiting frame 8; a connecting frame 17 is hinged to the second fixing frame 15 through a hinge seat 16, and the hinge seat 16 allows the connecting frame 17 to freely rotate within a certain angle range to adapt to different hoisting and construction requirements; a first fixing seat 18 is rotatably connected to the connecting frame 17, and the first fixing seat 18 can be directly connected to the robotic arm of the crane, increasing the connection stability between the pile driver and the hoisting equipment and ensuring safety and stability during hoisting and construction; a plug pin 19 is arranged on the first fixing seat 18, and the plug pin 19 is used to lock the first fixing seat 18 and the robotic arm of the crane to prevent accidental loosening or detachment during hoisting and construction.

[0031] First, remove the plug pin 19 from the first fixing seat 18. Then, directly align and connect the first fixing seat 18 with the robotic arm of the crane. After the connection is completed, reinsert the plug pin 19 to lock the connection between the first fixing seat 18 and the robotic arm of the crane in this way. In this way, the connection stability between the pile driver and the hoisting equipment can be significantly increased, ensuring safety and stability during hoisting and construction.

[0032] Please refer to Figure 6 and Figure 7 , a second fixing seat 20 is fixedly connected to the top of the first fixing frame 7, and an annular groove is provided on the second fixing seat 20; fixing sleeves 21 are symmetrically distributed front and back on the limiting frame 8, and the fixing sleeves 21 are located above the second fixing seat 20; three evenly distributed clamping blocks 22 are rotatably installed on the side of each fixing sleeve 21. After the second fixing seat 20 moves upward into the fixing sleeve 21, the clamping blocks 22 can be clamped into the annular groove to lock and fix it; a torsion spring 23 is sleeved at the rotating connection of the clamping block 22 and the fixing sleeve 21, and the torsion spring 23 can keep the clamping block 22 in the locked position when not affected by external forces.

[0033] When the pile driver is performing pile driving operations, if it encounters a large vibration force rebound that causes the machine to move upward, the second fixing seat 20 also rises and enters the fixing sleeve 21. Under the elastic force of the torsion spring 23, the clamping block 22 rotates and is clamped into the annular groove of the second fixing seat 20, forming a stable locking state, thereby locking the vibration box 1 and ensuring the stability of the vibration box 1 during pile driving to prevent damage caused by excessive vibration.

[0034] Please refer to Figure 8 and Figure 9, both left and right sides of the vibration box 1 are fixedly connected with second mounting frames 24; a cylinder 25 is installed at the lower part of the second mounting frame 24; a limiting plate 26 for restricting the position of the pile body is connected to the movable rod of the cylinder 25. The limiting plate 26 can be adjusted in position according to the size of the pile body and the pile driving requirements. A number of convex strips 27 are distributed on the surface of the limiting plate 26 in contact with the pile body. The convex strips 27 can increase the friction force and play an anti-slip role when the limiting plate 26 performs the limiting work.

[0035] Before or during the pile driving operation, the operator can adjust the distance between the two limiting plates 26 and the pile body by controlling the telescopic movement of the movable rod of the cylinder 25. When it is necessary to restrict the position of the pile body, the operator controls the cylinder 25 to extend its movable rod, so that the two limiting plates 26 clamp the pile body, preventing the pile body from shaking during the pile driving process, thereby ensuring the accuracy of the pile driving operation and the stability of the structure.

[0036] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
