[0030] Working principle:

[0031] Second plate adjustment process:

[0032] The device is hoisted to the location where piling is required, and then the second plate 4 is adjusted according to the terrain, and the external power supply of the third motor 302 is turned on and started, and the third motor 302 drives the threaded rod 303 to rotate, and the threaded rod 303 drives the nut 304 to move leftward (such as Figure 7), the nut 304 drives the U-shaped block 305 to move, and the U-shaped block 305 is connected to the lower end of the block 306 through a slide groove, so that the U-shaped block 305 drives the block 306 to swing on the first plate body 1, and the block 306 drives the two third connecting rods 307 to swing. Since the two third connecting rods 307 are fixed on the block body 306, when the block body 306 swings, the third connecting rod 307 at the left end is higher than the third connecting rod 307 at the right end, and the third connecting rod 307 drives the second plate body 4 to slide in the first plate body 1 through the slide groove. The height of the second plate body 4 at both ends will be adjusted with the swing height of the third connecting rod 307 at both ends. The two second plate bodies 4 are adjusted according to the terrain. After the second plate body 4 is adjusted to a suitable position, the third motor 303 is turned off. In the above method, the third motor 302 is reversed to drive the two second plate bodies 4 to reset. In the above method, the adjustment of the height of the second plate body 4 according to different terrains is completed.

[0033] Piling process in Guanzhuang:

[0034] The external power supply of the first motor 5 is turned on and started, the first motor 5 drives the pulley 6 to rotate, the pulley 6 drives the rod body 7 to rotate, the rod body 7 drives the connecting rod 8 to rotate, the connecting rod 8 drives the drill rod 9 to rotate, and the drill rod 9 performs piling work on the concrete in the pipe pile. When the rod body 7 rotates to the lowest end, the top of the rod body 7 will be stuck on the pulley 6 to prevent the rod body 7 from falling into the pipe pile. Then the first motor 5 is stopped, and then the rod body 7 is moved out of the slide groove of the pulley 6, and then the bolts on the surface of the rod body 7 are screwed to cancel the fixation of the connecting rod 8, and another connecting rod 8 is externally connected in the above manner to increase the piling depth of the drill rod 9 in the pipe pile. The rod body 8 is reset in the above manner, and the first motor 5 is started. The first motor 5 drives the drill rod 9 to continue to rotate so that the drill rod 10 continues to perform piling work;

[0035] When encountering harder concrete, the first shell 201 is moved to the left (eg Figure 2 ), after the first housing 201 moves to a suitable position, the first housing 201 is stopped, the bolts on the surface of the first housing 201 are screwed to make it abut against the first plate 4 to fix the first housing 201, the second motor 202 is connected to an external power supply and started, and the second motor 202 drives the protrusion 203 to rotate clockwise (such as Figure 5), the first connecting rod 206 swings downward along with the surface of the protrusion 203, and the middle part of the first connecting rod 206 swings on the second connecting rod 204. When the surface of the protrusion 203 lifts the right end of the first connecting rod 206, the left end of the first connecting rod 206 will swing downward. At this time, the spring 205 is stretched, and the first connecting rod 206 fits with the top of the rod body 7 to knock it. When the top of the protrusion 203 does not fit with the right end of the first connecting rod 206, the spring 205 rebounds and drives the first connecting rod 206 to reset. In the above manner, the first connecting rod 206 reciprocates to knock on the rod body 7 to increase the self-gravity of the rod body 7 and the drill rod 9, thereby increasing the strength of the drill rod 9 to pile on the concrete with greater hardness. After the piling is completed, the second motor 202 and the first motor 5 are turned off, and the first shell 201 is reset in the above manner, and then the device is removed from the pile. The piling work is completed in the above manner.
