In this construction ship, when the driving rotating rod and the transmission connection block move downward, the roller clamping block can be clamped to the transmission clamping block and drive the drill bit roller to rotate for drilling operations through the transmission connection between the transmission connection block and the drilling connection sleeve. When the driving rotating rod and the transmission connection block move upward, the transmission connection between the transmission connection block and the drilling connection sleeve is released, and the roller clamping block can be re-clamped to the transmission clamping block. At this time, it can drive the adjusting roller to rotate to adjust the positions of the construction pile body and the drilling sleeve. Description of the Drawings

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a construction ship and a construction method for driving a single-pile foundation. Embodiment 1

[0041] Please refer to Figure 1 - Figure 10 , a construction ship, including a pile driving hull 1, a pile driving mechanism 2 is installed inside the pile driving hull 1, a lifting mechanism 3 is installed outside the pile driving hull 1, and a driving mechanism 4 is installed outside the pile driving hull 1;

[0042] The pile driving mechanism 2 includes a pile driving turntable 21, the pile driving turntable 21 is rotatably installed inside the pile driving hull 1, a construction pile body 24 and a drilling sleeve 25 are slidably installed inside the pile driving turntable 21, a drill rod partition plate 26 is installed inside the drilling sleeve 25, and a construction drill bit 27 is installed inside the drill rod partition plate 26;

[0043] The lifting mechanism 3 is installed on one side of the pile driving mechanism 2, the driving mechanism 4 is located above the pile driving mechanism 2, the driving mechanism 4 can drive the pile driving turntable 21 to rotate inside the pile driving hull 1, when the pile driving turntable 21 rotates, it can adjust the positions of the construction pile body 24 and the drilling sleeve 25, the driving mechanism 4 can drive the construction drill bit 27 to rotate for drilling operations, the lifting mechanism 3 can limit the positions of the construction pile body 24 and the drilling sleeve 25, and the lifting mechanism 3 can drive the construction pile body 24 and the drilling sleeve 25 to move up and down inside the pile driving turntable 21.

[0044] During operation, first, the position of the pile sinking hull 1 is fixed according to the position of the pile sinking. After the position of the pile sinking hull 1 is fixed, the lifting mechanism 3 drives the drilling sleeve 25 to move downward from the initial position. After the position of the drilling sleeve 25 has dropped, the driving mechanism 4 drives the construction drill bit 27 to rotate forward inside the drilling sleeve 25. When the construction drill bit 27 rotates forward inside the drilling sleeve 25, it gradually moves downward from the initial position through the threaded connection with the drill rod separating disc 26. During the downward movement of the construction drill bit 27, drilling operations can be carried out. After drilling is completed, the driving mechanism 4 drives the construction drill bit 27 to rotate reversely inside the drilling sleeve 25. When the construction drill bit 27 rotates reversely inside the drilling sleeve 25, it moves upward to the initial position through the threaded connection with the drill rod separating disc 26. After the construction drill bit 27 returns to the initial position, the lifting mechanism 3 drives the position of the drilling sleeve 25 to rise back to the initial position. After the drilling sleeve 25 returns to the initial position, the lifting mechanism 3 drives the pile sinking turntable 21 to rotate 180°. When the pile sinking turntable 21 rotates, it can drive the construction pile body 24 and the drilling sleeve 25 to rotate synchronously, so as to exchange the positions of the construction pile body 24 and the drilling sleeve 25. After the construction pile body 24 rotates to the position of the drilling sleeve 25, the lifting mechanism 3 drives the construction pile body 24 to move downward. During the downward movement of the construction pile body 24, it can be extruded into the hole drilled by the construction drill bit 27. During the drilling construction process, the pile sinking turntable 21 is provided to drive the construction pile body 24 and the drilling sleeve 25 to rotate. After drilling is completed, the pile sinking turntable 21 can drive the construction pile body 24 to immediately move above the drill hole, thus avoiding the secondary search and positioning of the drill hole and greatly reducing the drilling and pile sinking construction time. Embodiment 2

[0045] The difference from the above embodiment is that, please refer to Figure 1 - Figure 10 On the outside of the pile sinking turntable 21, a turntable gear 22 is installed. On the top of the pile sinking turntable 21, a rotation limiting disc 23 is installed. On the outside of the construction drill bit 27, a lifting thread 28 is provided. A transmission sleeve 29 is slidably installed on the outside of the construction drill bit 27. On the outside of the transmission sleeve 29, a drill bit roller 210 is installed. On the top of the pile sinking hull 1, an adjusting gear 211 is rotatably installed. Inside the adjusting gear 211, an adjusting rotating rod 212 is installed. On the top of the adjusting rotating rod 212, an adjusting roller 213 is installed.

[0046] The top of the construction drill bit 27 is slidably connected to the inside of the transmission sleeve 29. The outside of the construction drill bit 27 is threadedly connected to the inside of the drill rod separating disc 26 through the lifting thread 28. The top of the transmission sleeve 29 is drivingly connected to the driving mechanism 4 through the drill bit roller 210. The top of the adjusting rotating rod 212 is drivingly connected to the driving mechanism 4 through the adjusting roller 213. The outside of the adjusting gear 211 is drivingly connected to the turntable gear 22 on the outside of the pile sinking turntable 21;

[0047] When the transmission sleeve 29 rotates, it can drive the construction drill bit 27 to rotate synchronously. When the construction drill bit 27 rotates, it can move up and down through the threaded connection with the drill rod separator 26. When the adjusting gear 211 rotates, it can drive the pile driving turntable 21 to rotate synchronously through the turntable gear 22. When the pile driving turntable 21 rotates, it can drive the rotating limit plate 23 to rotate synchronously.

[0048] The lifting mechanism 3 includes a lifting motor 31, which is installed on the top of the pile sinking hull 1. A motor roller 32 is installed on the driving end of the lifting motor 31, and a lifting transmission belt 33 is installed on the outside of the motor roller 32. A sliding mounting frame 34 is slidably installed on the top of the pile sinking hull 1, and a lifting roller 35 is rotatably installed inside the sliding mounting frame 34. A roller wheel 36 is installed on the rotating shaft of the lifting roller 35, and a limiting mechanism 37 is installed on the top of the rotating limit plate 23.

[0049] The outside of the lifting motor 31 is connected to the outside of the slide mounting frame 34 .

[0050] The limiting mechanism 37 includes a mounting base 371, which is fixedly mounted on the top of the rotating limiting plate 23. A plurality of limiting blocks 372 are slidably mounted on the top of the mounting base 371. The plurality of limiting blocks 372 are connected by limiting springs 373 and telescopic connecting rods 374. The outside of the limiting blocks 372 fits with the construction pile body 24 and the drilling sleeve 25.

[0051] The limiting spring 373 can drive the limiting block 372 to move to both sides, and the limiting block 372 can limit the positions of the construction pile body 24 and the drilling sleeve 25 on both sides.

[0052] The motor roller 32 and the roller roller 36 are connected by a lifting transmission belt 33, the outside of the lifting roller 35 contacts the outside of the drilling sleeve 25, and the outside of the sliding mounting frame 34 contacts the outside of the rotating limit plate 23;

[0053] The lifting motor 31 can drive the lifting roller 35 to rotate through the lifting transmission belt 33. When the lifting roller 35 rotates, it can drive the drilling sleeve 25 to move up and down inside the pile driving turntable 21. When the rotating limit plate 23 rotates, it can drive the sliding mounting frame 34 to slide outside the pile driving hull 1 through contact with the sliding mounting frame 34. When the sliding mounting frame 34 moves, it can drive the lifting motor 31 to move synchronously.

[0054] During operation, both sides of the limit block 372 are in contact with the construction pile 24 and the outer part of the drilling sleeve 25 respectively. Driving the limit block 372 to move to both sides through the limit spring 373 can limit the positions of the construction pile 24 and the drilling sleeve 25 through the limit block 372, preventing the construction pile 24 and the drilling sleeve 25 from sliding down inside the pile sinking turntable 21. The lifting motor 31 can drive the lifting roller 35 to rotate inside the sliding mounting frame 34 through the lifting transmission belt 33. When the lifting roller 35 rotates, it can drive the drilling sleeve 25 in contact with it to move up and down. When the construction pile 24 contacts the lifting roller 35, the rotation of the lifting roller 35 will also drive it to move up and down. Moreover, the outer parts of the drill bit roller 210 and the adjusting roller 213 are both in external transmission connection with the driving mechanism 4. When the drill bit roller 210 rotates, it can drive the construction drill bit 27 to rotate through the transmission sleeve 29 for drilling operations. When the adjusting roller 213 rotates, it can drive the adjusting gear 211 to rotate through the adjusting rod 212. When the adjusting gear 211 rotates, it can drive the pile sinking turntable 21 to rotate through the turntable gear 22 outside the pile sinking turntable 21. When the pile sinking turntable 21 rotates, it can drive the rotating limit disk 23 to rotate. When the rotating limit disk 23 rotates, the protrusions on the outside can drive the sliding mounting frame 34 to move outwards, and the sliding mounting frame 34 can also drive the lifting motor 31 to move synchronously during the movement. After the pile sinking turntable 21 finishes rotating, the sliding mounting frame 34 moves inwards, and the lifting roller 35 continues to contact the construction pile 24 or the drilling sleeve 25. During operation, the outer part of the lifting roller 35 is continuously in contact with the outer part of the construction pile 24 or the drilling sleeve 25, and when the lifting roller 35 rotates, it can drive the construction pile 24 or the drilling sleeve 25 to move up and down. When the pile sinking turntable 21 rotates to exchange the positions of the construction pile 24 and the drilling sleeve 25, the position of the lifting roller 35 can be limited through the rotating limit disk 23, and the limiting mechanism 37 on the rotating limit disk 23 can also effectively prevent the construction pile 24 and the drilling sleeve 25 from sliding down during the position exchange process. Embodiment III

[0055] The difference from the above embodiment is as follows. Please refer to Figure 1 - Figure 10, the driving mechanism 4 includes a transmission support frame 41, the transmission support frame 41 is installed on the top of the pile driving hull 1, a transmission mounting disc 42 is slidably installed outside the transmission support frame 41, a lifting hydraulic rod 43 is installed on the top of the transmission mounting disc 42, the movable end of the lifting hydraulic rod 43 is connected to a lifting platform 44, a driving motor 45 is installed on the top of the lifting platform 44, the movable end of the driving motor 45 is connected to a driving rotating rod 46, a transmission clamping block 47 is installed outside the driving rotating rod 46, a rotating transmission roller 48 is slidably installed outside the driving rotating rod 46, a roller clamping block 49 is installed inside the rotating transmission roller 48, a transmission connecting block 410 is slidably installed outside the driving rotating rod 46, a drilling transmission roller 411 is installed on the top of the transmission mounting disc 42, a drilling connecting sleeve 412 is installed on the top of the drilling transmission roller 411, a rotating transmission belt 413 is installed outside the rotating transmission roller 48, and a drilling transmission belt 414 is installed outside the drilling transmission roller 411.

[0056] The top of the transmission sleeve 29 passes through the inside of the transmission mounting disc 42, and the outside of the transmission sleeve 29 is rotatably connected to the inside of the transmission mounting disc 42. The center of the rotating shaft of the drilling transmission roller 411 coincides with the center of the pile driving turntable 21. The outside of the drilling transmission roller 411 is drivingly connected to the drill bit roller 210 through the drilling transmission belt 414, and the bottom of the transmission connecting block 410 is clamped inside the drilling connecting sleeve 412;

[0057] When the pile driving turntable 21 drives the drilling sleeve 25 to rotate, it can drive the transmission mounting disc 42 to rotate along the outside of the transmission support frame 41 through the transmission sleeve 29. The driving rotating rod 46 and the drilling transmission roller 411 are drivingly connected through the transmission connecting block 410 and the drilling connecting sleeve 412. When the driving rotating rod 46 rotates, it can drive the drilling transmission roller 411 to rotate synchronously.

[0058] The outside of the driving rotating rod 46 is clamped to the outside of the rotating transmission roller 48 and the transmission connecting block 410 through the transmission clamping block 47. The outside of the drilling transmission roller 411 is drivingly connected to the outside of the drill bit roller 210 through the drilling transmission belt 414. The outside of the rotating transmission roller 48 is drivingly connected to the outside of the adjusting roller 213 through the rotating transmission belt 413;

[0059] The lifting hydraulic rod 43 can drive the lifting platform 44 to move up and down. When the lifting platform 44 moves up and down, it can drive the driving rotating rod 46 to move synchronously. When the driving rotating rod 46 moves downward, the top of the drilling connecting sleeve 412 can limit the position of the rotating transmission roller 48. The inside of the rotating transmission roller 48 is clamped to the transmission clamping block 47 outside the driving rotating rod 46 through the roller clamping block 49.

[0060] When it is necessary to drive the drill roller 210 to rotate, the lifting hydraulic rod 43 contracts. When the lifting hydraulic rod 43 contracts, it can drive the lifting platform 44 to move downward. When the lifting platform 44 moves downward, the driving rod 46 and the transmission connecting block 410 will also move downward synchronously. And when the transmission connecting block 410 moves downward, it can be inserted into the inside of the drilling connection sleeve 412 and be in transmission connection with the drilling transmission roller 411 through the drilling connection sleeve 412. During the downward movement of the driving rod 46, the rotating transmission roller 48 is restricted by the drilling connection sleeve 412 and cannot move downward, so that the roller latch 49 inside the rotating transmission roller 48 is no longer engaged with the transmission latch 47. At this time, when the driving motor 45 drives the driving rod 46 to rotate, it can drive the transmission connecting block 410 to rotate synchronously through the engagement of the transmission latch 47 and the transmission connecting block 410. When the transmission connecting block 410 rotates, it can drive the drilling transmission roller 411 to rotate through the drilling connection sleeve 412. When the drilling transmission roller 411 rotates, it can drive the drill roller 210 to rotate through the drilling transmission belt 414, so as to perform drilling operations. When it is necessary to drive the adjusting roller 213 to rotate, the lifting hydraulic rod 43 extends. When the lifting hydraulic rod 43 extends, it can drive the lifting platform 44 to move upward. When the lifting platform 44 moves upward, it can drive the driving rod 46 and the transmission connecting block 410 to move upward. During the upward movement of the transmission connecting block 410, the transmission connection with the drilling connection sleeve 412 can be disengaged. During the upward movement of the driving rod 46, the roller latch 49 inside the rotating transmission roller 48 can be re-engaged with the transmission latch 47 outside the driving rod 46. At this time, when the driving motor 45 drives the driving rod 46 to rotate, it can drive the rotating transmission roller 48 and the transmission connecting block 410 to rotate simultaneously. When the rotating transmission roller 48 rotates, it drives the adjusting roller 213 to rotate through the rotating transmission belt 413. When the adjusting roller 213 rotates, it can drive the pile sinking turntable 21 to rotate through the adjusting gear 211. When the pile sinking turntable 21 rotates, it can drive the transmission mounting plate 42 to rotate along the outside of the transmission support frame 41 through the connection between the outside of the transmission sleeve 29 and the transmission mounting plate 42. During operation, the lifting hydraulic rod 43 is extended and contracted to drive the driving rod 46 and the transmission connecting block 410 to move up and down. When the driving rod 46 and the transmission connecting block 410 move downward, the engagement between the roller latch 49 and the transmission latch 47 can be released, and the drill roller 210 can be driven to rotate through the transmission connection between the transmission connecting block 410 and the drilling connection sleeve 412 to perform drilling operations. When the driving rod 46 and the transmission connecting block 410 move upward, the transmission connection between the transmission connecting block 410 and the drilling connection sleeve 412 is disengaged, and the roller latch 49 can be re-engaged with the transmission latch 47.
