Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and particularly relates to a welding and installation device for foundation embedded bolts of a photovoltaic bracket. Background Technique

[0002] A photovoltaic bracket is a matching bracket for installing and fixing photovoltaic panels. It can help the photovoltaic panels have a certain installation height after installation. At the same time, it can also enable the photovoltaic panels to be adjusted in angle after installation to obtain a good working angle.

[0003] Currently, most photovoltaic brackets are fixed by means of embedded bolts or expansion bolts. When using embedded bolts for installation, their bottoms are pre-embedded into the underlying concrete in advance. Then, the end of the upper optical axis can facilitate the passing of the through-hole of the bracket bottom plate. After passing through the through-hole, the external thread end at the top can directly install a nut, and finally, the photovoltaic bracket is fixed to the ground.

[0004] However, in actual use, the threads at the top of the embedded bolt are prone to damage during multiple installations or removals of the nut. At this time, because the position is fixed after embedding, if re-embedding is carried out, it will be very time-consuming. Therefore, the welding method is mostly used for repair, that is, the upper part of the embedded bolt is cut according to the situation, and then a new bolt is welded above the cutting position to facilitate quick repair. However, during traditional welding, the embedded bolt and the welding bolt are mostly aligned manually by hand. After a long time of alignment, the hand is prone to shaking, which seriously affects the concentricity of the welding fit between the embedded bolt and the welding bolt and is not convenient to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a welding and installation device for foundation embedded bolts of a photovoltaic bracket, which can improve the concentricity of the embedded bolt and the welding bolt during the alignment welding of the embedded bolt and the welding bolt, and is convenient for welding repair and use.
