Detailed Implementation

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on the present invention.

[0021] like Figures 1 to 6 The aforementioned high-efficiency steel pipe pile 10 pressure-driven pile driving device is installed at the stern of the hull 1 and includes a mounting base 2, a rotating base 3, and a pile hammer 4. A pile driving opening 5 is opened at the stern of the hull 1, and an adjustment groove 6 is opened near the pile driving opening 5. An adjustment track 7 is provided in the adjustment groove 6. The bottom of the mounting base 2 slides along the adjustment track 7 within the adjustment groove 6. The rotating base 3 is rotatably sleeved on the mounting base 2, and at least two sets of clamping seats 8 are symmetrically arranged on the top of the rotating base 3. A guide seat 9 is provided at the bottom of the rotating seat 3, corresponding to the bottom of each set of clamping seats 8. Each set of clamping seats 8 and guide seat 9 corresponds to a set of steel pipe piles 10. The pile hammer 4 is movably suspended on the upper part of the installation stand 2 by the steel wire rope 11. The installation stand 2 and the rotating seat 3 are both provided with slide rails 12. The pile hammer 4 slides up and down along the slide rails 12. A top clamping assembly is also provided at the center of the lower part of the pile hammer 4. The pile hammer 4 is fixed to the inner wall of the top of the steel pipe pile 10 by the top clamping assembly.

[0022] A gear ring 13 is provided below the guide seat 9 on the rotating seat 3. A rotary motor 14 is provided at the bottom of the mounting seat 2 corresponding to the gear ring 13. A rotary gear 15 is provided at the output end of the rotary motor 14. The rotary gear 15 meshes with the inner side of the gear ring 13 for transmission. The rotary motor 14 drives the rotating seat 3 to rotate along the mounting seat 2.

[0023] The guide seat 9 includes a guide base 16, a first drive cylinder 17, a first clamping cylinder 18, and a guide wheel 19. Two sets of guide bases 16 are symmetrically arranged at the bottom of the rotating seat 3. Each set of guide bases 16 has a guide clamping arm 20 movably hinged to one end. Each set of guide clamping arms 20 is movably hinged to one side of the corresponding guide base 16 via the first drive cylinder 17. The inner sides of the two sets of guide bases 16 and the inner sides of the two sets of guide clamping arms 20 are radially arranged in a centrally symmetrical manner. The inner output end of each set of first clamping cylinders 18 is correspondingly equipped with a guide wheel 19. The guide wheel 19 rolls against the outer wall of the steel pipe pile 10. The first drive cylinder 17 enables the guide clamping arm 20 to clamp the steel pipe pile 10. Subsequently, the first clamping cylinder 18 and the guide wheel 19 roll against the outer wall of the steel pipe pile 10, thereby achieving a good limiting effect on the steel pipe pile 10 and improving the accuracy of subsequent pile driving.

[0024] The clamping base 8 includes a clamping base 21, a second driving cylinder 22, a second clamping cylinder 23, and a fixed clamping sleeve 24. Two sets of clamping bases 21 are symmetrically arranged on the top of the rotating base 3. Each set of clamping bases 21 has a fixed clamping arm 25 movably hinged to one end. Each set of fixed clamping arms 25 is movably hinged to one side of the guide base 16 via the second driving cylinder 22. The inner sides of the two sets of clamping bases 21 and the inner sides of the two sets of fixed clamping arms 25 are radially arranged in a centrally symmetrical manner. Each set of second clamping cylinders 23 has a corresponding fixed clamping sleeve 24 installed on the inner output end. The inner side of the fixed clamping sleeve 24 is arc-shaped and fits in a limited and fixed fit with the outer wall of the steel pipe pile 10. The fixed clamping arm 25 can clamp the steel pipe pile 10 through the second driving cylinder 22. Subsequently, the second clamping cylinder 23 and the fixed clamping sleeve 24 abut against the outer wall of the steel pipe pile 10 for limited fixation, thereby fixing each set of steel pipe piles 10 in the clamping seat 8 and keeping it stable.

[0025] The slide rails 12 on the rotating base 3 are located between the two sets of clamping bases 21 and the two sets of guide bases 16. The slide rails 12 on the rotating base 3 can be matched and aligned with the slide rails 12 on the mounting base 2. Each set of slide rails 12 on the rotating base 3 can be adjusted to align with the upper slide rail 12 after rotation to avoid affecting the subsequent sliding of the pile hammer 4.

[0026] The top of the mounting base 2 is also equipped with a recovery disc 26 and a reversing wheel 27. There are two sets of recovery discs 26 and reversing wheels 27. The reversing wheels 27 are located on both sides directly above the pile hammer 4. There are two sets of wire ropes 11, which are wound around the recovery discs 26 through the reversing wheels 27. A recovery motor 28 is also installed on the top of the mounting base 2 between the two sets of recovery discs 26. The output end of the recovery motor 28 is synchronously driven with the rotating shaft of the two sets of recovery discs 26 through helical gears. The recovery motor 28 can realize the lifting and lowering of the pile hammer 4, thereby realizing the pressing and driving of the pile.

[0027] A slider 29 is provided on the inner side of the pile hammer 4 corresponding to the slide rail 12. Two sets of limiting wheels 30 are also provided on both sides of the slide rail 12. The two sets of limiting wheels 30 and the two sides of the slide rail 12 realize the relative fixation of the pile hammer 4 and the mounting base 2 in the horizontal direction, and the overall up and down movement of the pile hammer 4 is smoother.

[0028] The top clamp assembly includes a top arm 31, a fixed base 32, and an adjusting base 33. The upper part of the fixed base 32 is fixedly installed at the center of the bottom of the pile hammer 4. The bottom of the fixed base 32 has multiple sets of equidistant radially distributed movable slots 34. The top arm 31 is radially limited and movable within the movable slots 34. The adjusting base 33 is rotatably mounted at the center of the bottom of the fixed base 32. The adjusting base 33 has multiple sets of arc-shaped slots 35 corresponding to the top arm 31. A limiting movable block 36 is also provided inside each arc-shaped slot 35 on the top arm 31, limiting the movement within the arc-shaped slot 35. A transmission pulley 37 is also fixedly installed at the bottom of the adjusting base 33. An adjusting motor 38 is provided around the adjusting base 33 on the fixed base 32. The output end of the adjusting motor 38 is connected to... A drive pulley 39 and a transmission pulley 37 are connected to the drive pulley 39 via a synchronous belt 40. Each set of top arms 31 is also equipped with an anti-slip block on the outside. The outer side of the anti-slip block is limited and fitted against the inner wall of the top of the steel pipe pile 10. The pile hammer 4 is fixed and limited from the inside of the steel pipe pile 10 through the top clamp assembly. It can fix the steel pipe pile 10 when the clamping seat 8 is released. After the steel pipe pile 10 is fixed to the top clamp assembly, the pile hammer 4 is lowered to perform gravity pre-sinking of the steel pipe pile 10. If it is impossible to continue to go deeper into the seabed, the top clamp assembly is released to fix the steel pipe pile 10, and the pile hammer 4 is used to press and drive the pile into place. After the pile is driven, the pile hammer 4 is pulled up and the guide seat 9 is unfolded. The hull 1 then sails away to the next pile driving point.

[0029] The outer diameter of the pile hammer 4 is smaller than the inner diameter of the clamping seat 8 in the unfolded state. The pile hammer 4 slides up and down through the clamping seat 8 via the slide rail 12. The clamping seat 8 will not interfere with the up and down sliding stroke of the pile hammer 4 in the open state and in the retraction stroke state of the second clamping cylinder 23, thus ensuring the stability of the overall operation.

[0030] This invention, by setting multiple sets of fixed seats 32 and guide seats 9 on the rotating seat 3, can simultaneously fix multiple sets of steel pipe piles 10. Furthermore, since the rotating seat 3 can rotate along the mounting base 2, it can achieve the hoisting and fixing of steel pipe piles 10 while driving the piles, resulting in higher overall work efficiency.

[0031] The present invention improves the accuracy and stability of the steel pipe pile 10 during the pile driving process by setting a guide seat 9 at the bottom of the installation stand 2.

[0032] The present invention enables the mounting base 2 to be adjusted along the adjustment track 7, with a large overall adjustable range and the ability to fine-tune for precise positioning.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
