A second driving unit 9 for moving the winch 11 along the length direction of the moving seat 2 is provided at one end of the moving seat 2. A third driving unit 10 for driving the two limiting frames 6 to move towards each other or away from each other is provided on the lower side of the pile driving frame 1. Notches 12 are opened at both ends of the two limiting frames 6. Limiting rollers 13 are rotatably connected between the opposite side walls in each notch 12.

[0031] Specifically, when pile driving needs to be carried out on soft ground, the pile driving frame 1 is moved to the position where pile driving is required through the moving unit 8.

The moving seat 2 can be driven to move along the length direction of the upper part of the pile driving frame 1 through the first driving unit 7. The winch 11 can be moved along the length direction of the moving seat 2 through the second driving unit 9. Since the moving seat 2 and the pile driving frame 1 are in a cross shape, the horizontal and vertical positions of the winch 11 can be moved. The winch 11 is moved to the position where the pile rods are stacked. A lifting rope is wound inside the winch 11. The pile rod is lifted through the cooperation of the winch 11 and the lifting rope, and the pile rod is moved above the first through hole 4 again through the first driving unit 7 and the second driving unit 9. The pile rod is lowered through the winch 11 and the lower end penetrates into the first through hole 4. The two limiting frames 6 are driven to move towards each other through the third driving unit 10. A number of limiting rollers 13 are closely attached to the side of the pile rod to limit the pile rod. The pile driving unit 5 is started to carry out pile driving.

[0035] Specifically, when it is necessary to move the moving seat 2 along the pile driving frame 1, by driving the first driving motor 24, the output end of the first driving motor 24 drives the first lead screw 23 to rotate. When the first lead screw 23 rotates, it drives the first sliding block 21 to slide in the first sliding groove 22. When the first sliding block 21 moves, it drives the moving seat 2 to move along the first sliding groove 22, so as to realize the effect of moving the moving seat 2 along the upper length direction of the pile driving frame 1.

[0036] As a technical optimization solution of the present utility model, the moving unit 8 includes two bearing frames 25 fixedly installed at both ends of the pile driving frame 1.

[0039] Specifically, when it is necessary to move the winch 11 along the length direction of the moving seat 2, by starting the third driving motor 31, the output end of the third driving motor 31 drives the second lead screw 30 to rotate. The second lead screw 30 drives the second sliding block 28 to slide in the second sliding groove 29, and the second sliding block 28 drives the winch 11 to move along the length direction of the moving seat 2.

[0040] As a technical optimization scheme of the present utility model, the third driving unit 10 includes mounting plates 32 fixedly installed on the opposite side surfaces at both ends of the pile driver 1. Connecting plates 33 are fixedly connected to both opposite sides of the limiting frame 6.

One end of each of the two bidirectional lead screws 34 extends beyond one side of the mounting plate 32, and a transmission wheel 36 is fixedly installed on the side surface of each of them. A transmission belt 37 for transmission is sleeved between the side surfaces of the two transmission wheels 36. A fourth driving motor 35 fixedly connected to one end of the bidirectional lead screw 34 is fixedly installed on one mounting plate 32 through a mounting seat.

[0041] Specifically, when it is necessary to move the two limiting frames 6 towards or away from each other, by starting the fourth driving motor 35, the output end of the fourth driving motor 35 drives one transmission wheel 36 to rotate. This transmission wheel 36 drives the other transmission wheel 36 to rotate through the transmission belt 37. The two bidirectional lead screws 34 rotate simultaneously. The thread teeth on the side surfaces of the bidirectional lead screws 34 are oppositely and symmetrically arranged. Therefore, when the bidirectional lead screws 34 rotate, they will drive the two connecting plates 33 to move towards or away from each other, thereby realizing the movement of the limiting frames 6 towards or away from each other, and can be applicable to limiting pile rods of different thicknesses.

[0042] As a technical optimization scheme of the present utility model, counterweight frames 38 are fixedly installed on the opposite side walls inside the pile driver 1.
