Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] Please refer to Figures 1-5 As shown in the figure, the present invention is an improved structure of a ramming and expanding pile driver for compacted pile construction, including a base 1 and a pile cylinder 41, and a vibration damping mechanism 2 is arranged on the pile cylinder 41;

[0031] The vibration damping mechanism 2 includes a shock-absorbing sleeve 21 slidably connected to the inner wall of the pile cylinder 41. A connecting plate 24 is slidably connected to the inner wall of the shock-absorbing sleeve 21. The top surface of the connecting plate 24 is fixedly connected to a damper 22. The top end of the damper 22 is fixedly connected to the inner top wall of the shock-absorbing sleeve 21. The top surface of the connecting plate 24 is fixedly connected to a spring 23. The top end of the spring 23 is fixedly connected to the inner top wall of the shock-absorbing sleeve 21. The bottom end of the connecting plate 24 is fixedly connected to a plumb bob 25.

[0032] By setting the vibration damping mechanism 2, when the plumb bob 25 rams, the connecting plate 24 will slide upward in the shock-absorbing sleeve 21, the spring 23 is compressed, and the damper 22 starts to work. At this time, the transmission of vibration is greatly reduced. When the plumb bob 25 is lifted, the damper 22 and the damper 22 reset. The setting of the vibration damping mechanism 2 can reduce the vibration and noise directly transmitted to other parts of the machine and the surrounding environment during the ramming process, reduce the wear of each component of the machine, especially the connecting parts and fixing parts, and at the same time enhance the stability of ramming, improve the uniformity and effect of ramming, and greatly increase the ramming effect and service life of the machine.

The bottom surface of the fixing plate 51 is fixedly connected with a hydraulic telescopic rod 52, and the bottom end of the hydraulic telescopic rod 52 is fixedly connected with the top end of the shock-absorbing sleeve 21.

[0037] By providing the driving mechanism 3, during ramming, the pile cylinder 41 is buried into the ground to a certain depth. At this time, the ram 25 naturally drops to start ramming. After ramming is completed, the ram 25 is pulled up by the hydraulic telescopic rod 52 fixedly connected to the bottom surface of the fixing plate 51 for the next ramming. When a section of compacted pile is rammed, the first hydraulic telescopic rod 43 pushes against the fixing block 42 to drive the pile cylinder 41 to move upward, fill the filling port 44 with materials, and continue ramming to complete the next section of compacted pile. By repeating this process until the compacted pile is manufactured. The setting of the driving mechanism 3 can make the ram 25 ram more smoothly and accurately. At the same time, the pile cylinder can protect the pile body from possible lateral collisions and soil erosion during ramming, ensuring the integrity of the pile body and improving the ramming effect and efficiency.

[0038] Among them, as Figure 1 shown, a support seat 11 is fixedly connected to the top surface of the base 1. A cab 12 is fixedly connected to the top surface of the base 1. The bottom surface of the base 1 is rotatably connected with a chassis 13.

[0040] Among them, as Figure 2 and Figure 4 shown, a lifting mechanism 4 is provided on the base 1. The lifting mechanism 4 includes a lifting component and a positioning component;

[0041] The lifting assembly includes two first support ear plates 63 fixedly connected to the top surface of the base 1. The inner walls of the two first support ear plates 63 are each hinged with a second hydraulic telescopic rod 62. The inner wall of the support seat 11 is hinged with a lifting arm 61. The outer wall of the lifting arm 61 and the inner walls of the two second hydraulic telescopic rods 62 are each hinged.

[0042] Among them, as Figure 3 shown, the positioning assembly includes two third hydraulic telescopic rods 71 hinged to the outer wall of the lifting arm 61. Two second support ear plates 72 are fixedly connected to the right side of the C-shaped plate 31. One end of the two third hydraulic telescopic rods 71 away from the lifting arm 61 and the inner walls of the two second support ear plates 72 are each hinged.

[0043] By providing the lifting mechanism 4, when the C-shaped plate 31 needs to be lifted, the second hydraulic telescopic rod 62 connected to the first support ear plate 63 extends, pushing the lifting arm 61 to lift. When the C-shaped plate 31 needs to be lowered, the second hydraulic telescopic rod 62 retracts, and the C-shaped plate 31 naturally follows and descends. At the same time, when the position of the C-shaped plate 31 is adjusted, the third hydraulic telescopic rod 71 extends, and under the connection action of the second support ear plate 72, the orientation of the C-shaped plate 31 is adjusted to keep it vertical. The setting of the lifting mechanism 4 improves the efficiency and accuracy during ramming.

[0044] Among them, as Figure 3 shown, four hydraulic lifting columns 81 are fixedly connected to the bottom surface of the base 1.

[0045] By providing the hydraulic lifting columns 81, when the ramming and expanding pile driver moves to the designated position, the hydraulic lifting columns 81 extend to provide better stability for the machine. When the machine needs to move, the hydraulic lifting columns 81 contract, and the machine can move. The setting of the hydraulic lifting columns 81 improves the overall stability and service efficiency of the machine.

The setting of the vibration damping mechanism 2 can reduce the vibration and noise directly transmitted to other parts of the machine and the surrounding environment during ramming, reduce the wear of each component of the machine, especially the connecting parts and fixing parts, and at the same time enhance the stability of ramming, improve the uniformity and effect of ramming, and greatly increase the ramming effect and service life of the machine;

By cycling this process until the compacted pile is manufactured. The setting of the driving mechanism 3 enables the ram 25 to ram more smoothly and accurately.
