[0030] A stable pile driver for transportation construction comprises a base 1, the four corners of the lower end of the base 1 are fixedly connected with universal wheels 3, the upper front and rear ends of the base 1 are fixedly connected with a stabilizing device 2, the upper right end of the base 1 is fixedly connected with a load-bearing plate 4, the left end of the load-bearing plate 4 is fixedly connected with a support plate 5, the upper end of the support plate 5 is fixedly connected with a driving device 7, the left end of the support plate 5 is provided with a slide groove 6, and the left end of the driving device 7 is fixedly connected with an auxiliary device 8.

[0031] In this embodiment, the driving device 7 includes a No. 1 driving motor 71 and a No. 2 driving motor 76. The output end of the No. 1 driving motor 71 passes through the support plate 5 and is fixedly connected to a screw 72. The outer surface of the screw 72 is movably connected to a slide plate 74. The middle part of the upper end of the slide plate 74 is fixedly connected to a fixed plate 73. The output end of the No. 2 driving motor 76 passes through the slide plate 74 and is fixedly connected to a drill rod 75. The No. 1 driving motor 71 is fixedly connected to the upper end of the support plate 5. The auxiliary device 8 includes a No. 3 driving motor 81. The No. 3 driving motor The output end of the machine 81 passes through the fixed plate 73 and is fixedly connected to the rotating shaft block 82. The lower part of the outer surface of the rotating shaft block 82 is fixedly connected to a buffer column 83. The other end of the buffer column 83 is fixedly connected to a connecting rod 84. The lower end of the connecting rod 84 is fixedly connected to a hammer ball 85. The No. 3 driving motor 81 is fixedly connected to the left end of the fixed plate 73; the lower end of the screw rod 72 is movably connected to the lower plate wall of the support plate 5 through a bearing, and the slide plate 74 is slidably connected in the slide groove 6; the bottom of the hammer ball 85 is tightly attached to the upper end of the slide plate 74.

[0032] Through the above scheme: the first drive motor 71 is started, and its output end drives the screw 72 to rotate. Since the lower end of the screw 72 is movably connected to the lower plate wall of the support plate 5 through a bearing, and the slide plate 74 is movably connected to the screw 72 and slidably connected in the slide groove 6, the rotation of the screw 72 will be converted into an up and down linear motion of the slide plate 74 in the slide groove 6. When the slide plate 74 moves to a suitable position, the second drive motor 76 is started, and its output end drives the drill rod 75 to rotate, thereby performing a drilling operation. The third drive motor 81 is started, and its output end drives the shaft block 82 to rotate, thereby driving the buffer column 83, the connecting rod 84 and the hammer ball 85 to rotate together. Since the bottom of the hammer ball 85 is tightly attached to the slide plate 7 4, which will produce periodic hammering effect on the slide plate 74 during its rotation, thereby enhancing the piling effect. Through the cooperation of the No. 1 driving motor 71 and the screw 72, the upper and lower positions of the slide plate 74 can be accurately controlled, thereby accurately adjusting the height of the drill rod 75 to meet the piling requirements of different depths. The No. 2 driving motor 76 directly drives the drill rod 75 to rotate, providing stable drilling power and improving drilling efficiency and quality. The No. 3 driving motor 81 drives the hammer ball 85 to hammer the slide plate 74, providing additional impact force for the piling process, which helps to improve the speed and effect of piling. The buffer column 83 can play a buffering role during hammering, reduce impact damage to the device, and extend the service life of the equipment.

[0033] In this embodiment, the stabilizing device 2 includes a hydraulic cylinder 21, and two hydraulic cylinders 21 are provided. The output ends of the two hydraulic cylinders 21 both penetrate the base 1 and are fixedly connected to the bottom plate 22. The left front end and the left rear end of the bottom plate 22 are both interspersed with an insertion plate 23. The lower left end and the lower right end of the two insertion plates 23 are both fixedly connected with a suction cup seat 24. The two hydraulic cylinders 21 are respectively fixedly connected to the upper front end and the upper rear end of the base 1; the four suction cup seats 24 are not in contact with the four universal wheels 3.

[0034] Through the above scheme: when the pile driver needs to work in a fixed position, the two hydraulic cylinders 21 are started, and the output end pushes the bottom plate 22 to move downward, and the suction cup seat 24 on the interleaved plate 23 contacts the ground. Through the adsorption effect of the suction cup and the support of the bottom plate 22, the contact area and stability of the pile driver with the ground are increased. The combination of the two hydraulic cylinders 21 and the bottom plate 22 can provide strong supporting force to ensure that the pile driver remains stable during work and reduce shaking and displacement. The design of the interleaved plate 23 and the suction cup seat 24 increases the contact area and adsorption force with the ground, further improving the stability, especially on uneven ground, it can effectively prevent the pile driver from tilting or shifting, and ensure the accuracy and safety of construction.

[0035] It should be noted that the utility model is a stable pile driver for transportation construction. During use, the universal wheel 3 at the lower end of the base 1 makes the entire pile driver flexible in movement, which is convenient for position adjustment in the construction site. When the pile driver moves to the designated position and needs to work, the two hydraulic cylinders 21 are started, and the output ends thereof push the bottom plate 22 to move downward, and the interlaced plate 23 on the bottom plate 22 and the suction cup seat 24 at the lower end thereof contact the ground. Through the adsorption effect of the suction cup seat 24 and the support of the bottom plate 22, the contact area and stability of the pile driver with the ground are increased, and the machine is prevented from shaking or displacement during the piling process. The machine 71 is started, and its output end drives the screw 72 to rotate. Since the slide plate 74 is movably connected to the screw 72 and is slidably connected in the slide groove 6, the rotation of the screw 72 will cause the slide plate 74 to move up and down along the slide groove 6, thereby adjusting the height position of the drill rod 75. When the No. 2 drive motor 76 is started, its output end drives the drill rod 75 to rotate to achieve drilling operations of different depths. The No. 3 drive motor 81 is started, and its output end drives the shaft block 82 to rotate, thereby causing the buffer column 83, the connecting rod 84 and the hammer ball 85 to rotate together. The hammer ball 85 produces a periodic hammering effect on the slide plate 74 during the rotation process, thereby enhancing the piling effect.
