[0040] Working principle and usage process of the utility model: When in use, first set the ground pile on the top of the pile press through the crane of the pile press. After setting, turn the fastening bolt 95 with a tool to make the fastening bolt 95 away from the second clamping block 92 and the third clamping block 93. After moving away, remove the third clamping block 93 and turn the fastening bolt 95 in the reverse direction again to fix the second clamping block 92. After fixing, start the motor 3. The output end of the motor 3 drives the rotating rod 4 to rotate. The rotating rod 4 drives the turntable 5 to rotate. The turntable 5 drives the traction rod 6 to rotate. When the traction rod 6 rotates, it pushes the limit frame 7 to move inward. The limit frame 7 drives the connecting plate 8 to move inward. The connecting plate 8 drives the first clamping block 91 and the second clamping block 92 to move inward. After the output end of the motor 3 rotates 180 degrees, it stops rotating, so that the second clamping block 92 is sleeved on the surface of the ground pile to stabilize the ground pile. Finally, if it is necessary to stabilize more ground piles with different diameters, start the motor 3 again to rotate 180 degrees, so that the first clamping block 91 is reset and the remaining clamping blocks can be removed or added.

[0041] To sum up: For the pile press with good stability, by setting the ground pile on the top of the pile press through the crane of the pile press, after setting, turn the fastening bolt 95 with a tool to make the fastening bolt 95 away from the second clamping block 92 and the third clamping block 93. After moving away, remove the third clamping block 93 and turn the fastening bolt 95 in the reverse direction again to fix the second clamping block 92. After fixing, start the motor 3. The output end of the motor 3 drives the rotating rod 4 to rotate. The rotating rod 4 drives the turntable 5 to rotate. The turntable 5 drives the traction rod 6 to rotate. When the traction rod 6 rotates, it pushes the limit frame 7 to move inward. The limit frame 7 drives the connecting plate 8 to move inward. The connecting plate 8 drives the first clamping block 91 and the second clamping block 92 to move inward. After the output end of the motor 3 rotates 180 degrees, it stops rotating, so that the second clamping block 92 is sleeved on the surface of the ground pile to stabilize the ground pile. Finally, if it is necessary to stabilize more ground piles with different diameters, start the motor 3 again to rotate 180 degrees, so that the first clamping block 91 is reset and the remaining clamping blocks can be removed or added. Thus, it has the advantage of good stability, and solves the problem that the calibers of the limiters of existing pile presses are mostly fixed, which leads to the phenomenon of slight shaking when installing ground piles with smaller diameters, and requires users to use external instruments for limiting, reducing the practicability of the pile press.
