The motor 1 51 is operated by the control switch group 20. The output shaft of the motor 1 51 rotates to drive the rotating shaft 52, which in turn drives the driving gear 53 to rotate. The driving gear 53 rotates to drive the transmission gear 54. The transmission gear 54 acts on the inner gear ring. The rotation of the inner gear ring drives the sliding seat 3 to rotate, which in turn causes the steering seat 4 to rotate.

[0025] Among them: the front end of the steering seat 4 is rotatably connected to the adjusting seat 13, the front end of the adjusting seat 13 is fixedly connected to the sliding frame 14, the internal sliding connection of the sliding frame 14 is connected to the sliding plate 17, the interior of the sliding plate 17 is matched with the outer surface of the hydraulic hammer 18, the internal rotatable connection of the sliding frame 14 is connected to the screw rod 15, the middle part of the screw rod 15 is threadedly connected to the rear end of the sliding plate 17, the upper end of the sliding frame 14 is provided with a motor 2 16, the lower end of the output shaft of the motor 2 16 is fixedly connected to the upper end of the screw rod 15, the middle part of the upper surface of the steering seat 4 is provided with a U-shaped seat 18, the upper end of the U-shaped seat 18 is rotatably connected to the rotating seat 9, the upper end of the rotating seat 9 is provided with a telescopic column 10, the oil inlet of the telescopic column 10 is connected to the oil port of the external hydraulic pump through the conduit 2, the upper end of the rear side surface of the sliding frame 14 is provided with a U-shaped seat 2 11, the internal rotatable connection of the U-shaped seat 2 11 is connected to the drive seat 12, and the rear end of the drive seat 12 is fixed to the telescopic end of the telescopic column 10 The input end of the motor 2 16 is electrically connected to the output end of the control switch group 20 to realize the operation of the external hydraulic pump. The external hydraulic pump supplies oil to the oil port of the telescopic column 10 through the conduit 2. The telescopic end of the telescopic column 10 extends and pushes the U-shaped seat 2 11 through the driving seat 12, thereby causing the sliding frame 14 to rotate under the action of the adjustment seat 13. The rotation of the sliding frame 14 drives the hydraulic hammer 18 to rotate through the sliding plate 17, thereby realizing the vertical angle adjustment of the hydraulic hammer 18, and then the operation of the motor 2 16 is realized by the control switch group 20. The output shaft of the motor 2 16 rotates to drive the screw rod 15 to rotate.

[0026] The working principle of a pile driver for water conservancy construction provided by the present invention is as follows: during operation, the personnel rotate the corresponding adjusting cylinder 64 through the driving handle 65 in turn according to the road surface requirements. The rotation of the adjusting cylinder 64 causes the two longitudinally adjacent screws 63 to move in the direction away from the center of the support platform 1, and the screws 63 push the corresponding support legs 7 to rotate outward, thereby lowering the height of the support platform 1 to achieve height adjustment of the support platform 1. When the support platform 1 moves to the required height, the personnel stops rotating the driving handle 65, and then connects the connecting hole at the rear end of the connecting plate 21 with the threaded hole of the external device through the connecting bolt, and then moves the pile driver to the required position through the external device. Then, the personnel realizes the operation of the motor 1 51 through the control switch group 20, and the output shaft of the motor 1 51 rotates to drive the rotating shaft 52 to rotate, thereby driving the driving gear 53 to rotate, and the driving gear 53 rotates to drive the transmission gear 54 to rotate, and the transmission gear 54 acts on the inner gear ring, and the rotation of the inner gear ring drives the sliding seat 3 to rotate, thereby causing the steering seat 4 to rotate, and the steering seat 4 rotates The adjusting seat 13 drives the sliding frame 14 to rotate horizontally, and then drives the hydraulic hammer 18 to rotate horizontally through the sliding plate 17. When the hydraulic hammer 18 rotates to the required position, the personnel turns off the motor 1 51 through the control switch group 20, and realizes the operation of the external hydraulic pump. The external hydraulic pump supplies oil to the oil port of the telescopic column 10 through the conduit 2. The telescopic end of the telescopic column 10 extends and pushes the U-shaped seat 2 11 through the driving seat 12, thereby causing the sliding frame 14 to rotate under the action of the adjusting seat 13. The sliding frame 14 rotates and drives the hydraulic hammer 18 through the sliding plate 17. The vertical angle of the hydraulic hammer 18 is adjusted by rotating the motor 2 16 , and then the motor 2 16 is operated by controlling the switch group 20 . The output shaft of the motor 2 16 rotates to drive the screw 15 to rotate. The screw 15 rotates to move the sliding plate 17 downward, thereby moving the hydraulic hammer 18 downward. When the hydraulic hammer 18 reaches the desired position, the motor 2 16 is turned off by controlling the switch group 20 , and the external hydraulic pump is operated to operate the hydraulic hammer 18 . The reciprocating up and down motion of the hammer head of the hydraulic hammer 18 drives the pile driving head 19 to reciprocate up and down, thereby fixing the pile body.
