[0011] A method for using a multifunctional automatic pile connection mechanical device is characterized in that: the multifunctional automatic pile connection mechanical device is used for construction, and the specific construction steps are as follows:

[0012] Step 1: Construction preparation

[0013] Check whether the CNC operation platform is operating normally, operate all parts of the equipment in advance, ensure the safety and reliability of the equipment, move the fixed frame to the side close to the wire reel through the transverse screw nut, and retract the clamp into the support beam through the hydraulic cylinder;

[0014] Step 2: Mobile device framework module

[0015] Through the CNC operating platform, the base is moved to the vicinity of the designed hole position of the pile to be connected, and the base is moved so that the hole position of the pile to be connected coincides with the center position of the clamp;

[0016] Step 3: Planting precast piles

[0017] Plant the precast piles at the designed hole position. When the length of the first section of the precast pile exposed above the ground is 50cm~150cm, start the hydraulic cylinder to tightly press the clamp and the first section of the precast pile, and dock the second precast pile with the first precast pile to ensure that the axes of the two precast piles coincide.

[0018] Step 4: Welding precast piles

[0019] The lateral movement motor is turned on through the numerical control operation platform, thereby driving the lateral screw nut to move, so that the fixed frame is close to the precast pile. When the guide contacts the precast pile, the lateral movement motor stops automatically, and the longitudinal movement motor is turned on at the same time, thereby driving the vertical screw nut to move, so that the fixed platform moves up or down. When the guide contacts the interface of the precast pile, the longitudinal movement motor is stopped, and the rotation motor is turned on to rotate the fixed platform along the guide rail. During the rotation process, the guide is always in close contact with the interface of the two precast piles, and the movement trajectory is recorded by the displacement sensor. At the same time, the fixed frame is controlled to make the scraper, welding gun, and flaw detector run along the trajectory of the guide, and the detection image is transmitted and recorded on the display of the numerical control operation platform. After the flaw detector rotates one circle, the fixed platform runs in the opposite direction to the starting point along the route recorded by the guide. During the reverse operation, secondary welding is performed according to the crack position recorded by the flaw detector.

[0020] Step 5: Move the welding construction module

[0021] After the welding is completed, the fixed frame is moved to the side close to the welding wire reel through the CNC operating platform, and the clamp is moved away from the prefabricated pile through the hydraulic cylinder. Then the second prefabricated pile is implanted, and steps 3 to 5 are repeated until all the prefabricated piles are welded;

[0022] Step 6: Construction completed

[0023] After welding is completed, the multifunctional automatic pile connection mechanical device is moved to the lower pile position through the CNC operating platform.

[0024] Preferably, the fixed platform rotates along the guide rail at a speed ranging from 0.02 r / min to 0.2 r / min.

[0025] Preferably, the detection accuracy range of the flaw detector is 0.1mm-2mm.

[0026] Beneficial technical effects brought by the present invention:

[0027] The present invention realizes the automatic welding operation of prefabricated piles by rotating welding along the circumference of the guide rail through servo drive adjustment; the setting of the guide ensures the accuracy of the welding position, the scraper and the flaw detector ensure the quality of the weld, and the reliability of the overall mechanical device ensures the stability and reliability of the final welding quality;

[0028] Technical workers with good professional skills are no longer needed. Ordinary workers can replace the special jobs that were originally required after simple training. In addition, possible injuries to workers during the welding process are avoided, and the mechanical device does not experience fatigue and can work continuously, which greatly reduces the cost and pressure of construction personnel.
