[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] 1. This invention incorporates scissor lifts with guide wheels installed at the center pin position and a counterweight base installed at the lower end of the scissor lift. The counterweight base has a large weight and remains on the ground due to its own weight when not subjected to external force. At this time, each scissor lift is in an extended state, with each guide wheel close to the outside of the pipe pile. When the upper clamping ring moves downward, causing the pipe pile to move downward, each scissor lift is in a retracted state. At this time, each guide wheel gradually approaches, still guiding the downward-moving pipe pile. This ensures that regardless of the length of the pipe pile, each guide wheel can guide the pipe pile, preventing it from swaying. In summary, the scissor lifts can open or retract with the lifting and lowering of the clamping ring to adjust the position of the guide wheels, ensuring that the guide wheels can guide the pipe pile from beginning to end, thus ensuring that the pipe pile remains vertical.

[0020] 2. This invention is equipped with an upper infrared ranging sensor and a lower infrared ranging sensor, as well as a comparator, a controller and a buzzer. The values ​​detected by the upper infrared ranging sensor and the lower infrared ranging sensor are compared by the comparator and the signal is transmitted to the controller. When the value compared by the comparator is within the acceptable error range, the controller will control the buzzer to sound, thereby prompting the operator that the pipe pile has been aligned with the mold and can be pressed down.

[0021] 3. The present invention sets the upper part of the clamping ring in a bucket shape, which increases the diameter of the opening on the clamping ring. This makes it easier to insert the pile head into the inside of the clamping ring after the pipe pile is hoisted, reducing the hoisting operation accuracy of the hoisting machine and facilitating the operation of the staff.

[0022] 4. The present invention is equipped with an angle adjustment component, which can avoid adjusting the orientation between the scissor bar and the pipe pile, thereby preventing the welding torch from blocking the welding of the two pipe piles. Attached Figure Description
