Detailed Implementation

[0027] Example 1

[0028] like Figure 1-5 As shown, the present invention proposes a pile driving device for anchor static pressure piles, including a fixed frame 1, a second hydraulic cylinder 5, a lifting block and an adjustment component;

[0029] The middle part of the lifting block is provided with an installation groove 15. Multiple Y-shaped blocks 6 are rotatably installed inside the installation groove 15 to position the precast pile in use and make it move up and down with the lifting block. In use, the lifting block can be rotated 180 degrees to change the connection direction between the Y-shaped blocks 6 and the precast pile.

[0030] The adjustment component is installed on the top of the lifting block, and its end extends to the inside of the lifting block and is located above one end of the Y-shaped block 6. The bottom end of the adjustment component is provided with a protrusion 10 for arranging multiple Y-shaped blocks 6 alternately along the height direction of the fixed frame 1 in the use state, and multiple Y-shaped blocks 6 can be arranged symmetrically in pairs in use.

[0031] The number of second hydraulic cylinders 5 is at least two. The two second hydraulic cylinders 5 are symmetrically installed on the top of the fixed frame 1 and the protruding ends extend to the inside of the fixed frame 1 and are connected to the lifting block. They are used to move the lifting block up and down in the fixed frame 1 during use, so that the lifting block drives the precast pile to perform pile driving through the Y-shaped block 6.

[0032] In this embodiment, by setting an installation groove 15 in the middle of the lifting block and arranging multiple Y-shaped blocks 6 to rotate around the lifting block at equal angles, and by adjusting the protrusion 10 at the bottom of the component, the Y-shaped blocks 6 are placed at different heights in the middle of the lifting block, avoiding interference caused by the synchronous rotation of multiple Y-shaped blocks 6. At the same time, the adjustment component moves towards the bottom of the installation groove 15, so that the adjustment component drives one end of multiple Y-shaped blocks 6 to move down synchronously in the protrusion 10 and rotate, so that the other end of multiple Y-shaped blocks 6 moves towards the middle of the lifting block and contacts the precast pile through the lever action. The shape of the Y-shaped blocks 6 limits the precast pile and firmly fixes the precast pile in the middle of the lifting block, ensuring that the precast pile is stable and does not deviate during the pile driving process. At the same time, the second hydraulic cylinder 5 drives the lifting block to move down, so that the lifting block applies uniform pressure to the precast pile through the Y-shaped blocks 6, realizing efficient pile driving operation.

[0033] Example 2

[0034] like Figure 1-2 As shown, the present invention proposes a pile driving device for anchor static pressure piles. Compared with Embodiment 1, the difference in this embodiment is that the lifting block includes a connecting shell 2 and a limiting plate 3.

[0035] The connecting shell 2 is located in the middle of the fixed frame 1 and is connected to the extended end of the second hydraulic cylinder 5;

[0036] The limiting plate 3 is located on the outside of the connecting shell 2 and is fitted and connected to the fixing frame 1.

[0037] In an optional embodiment, a connecting ring 8 is provided at the edge of the mounting groove 15 and at the middle of the connecting shell 2, and a rotating shaft 14 is provided at the middle of the Y-shaped block 6. The rotating shaft 14 is rotatably connected to the connecting ring 8, so that the Y-shaped block 6 can rotate on the connecting ring 8 through the rotating shaft 14, and the Y-shaped block 6 can be in a lever shape through the rotating shaft 14.

[0038] In an optional embodiment, a placement groove 13 is provided on the inner side of the connecting ring 8. The placement groove 13 is arranged to match the size of the Y-shaped block 6, and the placement groove 13 and the Y-shaped block 6 are arranged in a one-to-one correspondence. This is used to hold the Y-shaped block 6 during use and to prevent the connecting ring 8 from obstructing the rotation of the Y-shaped block 6.

[0039] In this embodiment, a connecting ring 8 is provided at the edge of the mounting groove 15 in the middle of the connecting shell 2, and the Y-shaped block 6 is rotatably connected to the connecting ring 8 through the rotating shaft 14, so that one end of the Y-shaped block 6 rotates in the mounting groove 15 and the other end rotates in the middle of the connecting shell 2, thereby allowing the Y-shaped block 6 to apply balanced pressure to the precast pile in the middle of the connecting shell 2, ensuring the stability of the pile driving process.

[0040] Example 3

[0041] like Figure 1-2 As shown, the present invention proposes a pile driving device for anchor static pressure piles. Compared with the first embodiment, the difference in this embodiment is that the adjusting component includes a first hydraulic cylinder 4 and a pressure ring 7.

[0042] The number of first hydraulic cylinders 4 is multiple, and all the first hydraulic cylinders 4 are located at the top of the connecting shell 2 and the protruding ends extend into the mounting groove 15.

[0043] The pressure ring 7 is located inside the mounting groove 15 and is connected to the extended end of the first hydraulic cylinder 4.

[0044] In this embodiment, the first hydraulic cylinder 4 drives the pressure ring 7 to move downward in the mounting groove 15, causing multiple Y-shaped blocks 6 to rotate synchronously within the mounting groove 15 via the rotating shaft 14. This ensures that each Y-shaped block 6 applies uniform pressure to the precast pile, improving the pile driving effect. Simultaneously, the presence of multiple first hydraulic cylinders 4, with their extended ends connected to the pressure ring 7, allows for inter-cylinder linkage, ensuring coordinated operation of all components during pile driving. This further optimizes the performance of the pile driving device and improves construction efficiency and safety.

[0045] Example 4

[0046] like Figure 1-2 As shown, the present invention proposes a pile driving device for anchor static pressure piles. Compared with the first embodiment, the difference in this embodiment is that the bottom ends of the pressure ring 7 and the protrusion 10 are provided with connecting blocks 9, the side of the connecting block 9 is provided with connecting grooves 11, and the end of the Y-shaped block 6 is provided with connecting posts 12, which are inserted into the connecting grooves 11.

[0047] In an optional embodiment, the connecting groove 11 is waist-shaped, which is used to drive the connecting post 12 to slide in the connecting groove 11 during use, so that the rotation of the Y-shaped block 6 is smoother.

[0048] In this embodiment, a connecting block 9 is provided at the bottom of the pressure ring 7, and the connecting block 9 is waist-shaped. When the pressure ring 7 moves one end of the Y-shaped block 6 up and down, the connecting block 9 moves the connecting post 12 in the connecting groove 11, ensuring that one end of the Y-shaped block 6 moves with the pressure ring 7.

[0049] In this invention, multiple first hydraulic cylinders 4 synchronously drive the pressure ring 7 to move downward in the mounting groove 15, causing the pressure ring 7 to synchronously move one end of multiple Y-shaped blocks 6 inside the mounting groove 15. The pressure ring 7 is rotatably connected to the connecting ring 8 via the rotating shaft 14, so that the other end of the Y-shaped blocks 6 moves towards and contacts the precast pile via the rotating shaft 14. This causes one end of the Y-shaped blocks 6 to wrap around the outside of the precast pile and limit its movement. At the same time, the pressure applied by the first hydraulic cylinders 4 causes the multiple Y-shaped blocks 6 to apply pressure to the precast pile simultaneously, firmly fixing the precast pile in the middle of the connecting shell 2. Meanwhile, the second hydraulic cylinder 5 drives the connecting shell 2 to move downward, causing the connecting shell 2 to move the precast pile downward through the friction generated by the pressure applied to the precast pile by the Y-shaped blocks 6, thus achieving efficient pile driving operation.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
