The utility model discloses a welding tool for cantilevers in trough photothermal power generation equipment, which comprises a vertical left and right columns with rolling bearings at the base and the top, and the rolling bearings are connected with the rotating axles at both ends of the support respectively; the shape of the support matches the shape of the cantilever to be welded, and the support includes an end face vertical plate, a lower bending beam and an upper bending beam welded into one. The lower and upper bending beams are perpendicular to the end vertical plates in the same plane. The lower and upper bending beams are provided with supporting columns with U-shaped fixing clips at the top, and the supporting columns are equipped with latch clamps or vertical clamps. The utility model realizes the welding operation of the special-shaped cantilever by clamping and fastening the bracket and latch clamp and vertical clamp installed at the top of two pillars to match the shape of the cantilever to be welded. The welding operation of the special-shaped cantilever can be realized by one clamping through the rotation of the rotating shaft at both ends of the bracket and the rolling bearing, thus reducing the clamping times, improving the working efficiency and product quality.
