Description

Technical Field

[0001] This utility model relates to the field of pipe-pulling pile welding technology, and in particular to a pipe-pulling pile welding device. Background Technology

[0002] Extractable pipe piles are hollow cylindrical precast piles made of concrete, steel, or composite materials. They are driven into the foundation through methods such as static pressure, hammering, vibration, or implantation to transfer the load from the superstructure to the deep bearing layer. During the fabrication of extractable pipe piles, welding is often required.

[0003] Currently, the welding process for pipe pile extraction still largely relies on the traditional method of manual welding. Welding is carried out manually using a welding torch. Welders need to hold the heavy welding torch for a long time, maintaining a fixed posture to perform circumferential welding around the pipe pile. Not only are their arms and waist prone to fatigue, but they also have to face the strong light, high temperature and harmful fumes generated during the welding process. After working continuously for several hours, welders will inevitably experience fatigue, leading to a slowdown in welding speed and a decrease in the stability of weld quality. Therefore, this utility model provides a pipe pile extraction welding device. Utility Model Content

The welding equipment includes a rotating tube 10 with a moving component inside, a fixed plate 18 inside the rotating tube 10 via the moving component, an adjusting component on the surface of the fixed plate 18, and a welding torch 22 on the surface of the fixed plate 18 via the adjusting component. A handrail 2 is fixedly installed on the top of the base 1, and pulleys 3 are installed at the bottom of the base 1. The pulleys 3 are self-locking casters. This pipe-pulling pile welding equipment uses a lifting component to move the moving frame 7 downward, so that the rotating tube 10 fits over the pipe-pulling pile from the top, moving the rotating tube 10 to a suitable height. At the same time, the distance between the welding torch 22 and the pipe-pulling pile is adjusted by the moving component, and the welding angle of the welding torch 22 is adjusted by the adjusting component. During the welding process, the rotating component allows the rotating tube 10 to rotate along the rotating component, and the welding torch 22 rotates with the rotation of the rotating tube 10, realizing automatic positioning and circumferential welding of the welding torch 22.

Then, the pipe-pulling pile is welded by the welding gun 22. During the welding process, the first gear 13 of the second motor 12 rotates, so that the second gear 14 rotates, causing the rotating tube 10 and the slide plate 9 to rotate along the slide rail 8, so that the welding gun 22 can rotate with the rotation of the rotating tube 10, thereby completing the welding of the pipe-pulling pile.
