Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic support installation, and in particular relates to a welding auxiliary tool for a pile foundation steel cage. Background Art

[0002] Steel pipe piles are widely used in photovoltaic support installation projects due to their simple structure, convenient installation, good adaptability to foundation connection, excellent anti-corrosion performance, and long service life. There are usually two ways to connect steel pipe piles to the foundation. One is bolt flange connection, which usually configures a flange at the bottom of the steel pipe pile, processes an elliptical hole on the top, and cooperates with the four pre-buried bolts in the foundation for fixed connection; the other is to directly weld it with the steel cage as a whole, insert it into the pre-guided foundation hole as a whole, and cast it into shape.

[0003] Among them, the welding of steel pipe piles and steel cages is mostly done on-site. During the welding, it is necessary to ensure the coaxiality and straightness of the two parts, and to fix the welding reliably to ensure that the photovoltaic bracket piles can be cast vertically and to ensure the installation quality of the photovoltaic module array. The length of the steel pipe piles and steel cages exceeds 2.5 meters. They cannot be vertically connected on site and can only be placed flat near the ground. The welding requires uniform and symmetrical welding throughout the whole circle, so the parts need to be flipped. Manual flipping of parts is heavy and difficult to operate; the secondary positioning after flipping will result in cumulative errors, which is not conducive to coaxiality quality control; the rigidity of the steel cage itself is weak, and the straightness is difficult to guarantee during the flipping process.
