The four third nozzles 1610 on the same rigid pipe 169 are evenly spaced.

[0043] When the lifting block 155 lifts the dried steel structure, the second wiping plate 166 will contact the left and right sides of the dried steel structure. The second wiping plate 166 can wipe off the debris on the left and right sides of the steel structure. Subsequently, the electric grinding roller four 165 will contact the left and right sides of the dried steel structure. The electric grinding roller four 165 can grind the left and right sides of the steel structure. The debris generated by grinding will enter the box body 131 through the third connecting pipe 168 and the second connecting pipe 167. Subsequently, the rigid pipe 169 is externally connected to the anti-corrosion paint liquid. The anti-corrosion paint liquid flows into the rigid pipe 169. Finally, the anti-corrosion paint liquid is sprayed out through the third nozzle 1610 and sprayed onto the left and right sides of the steel structure, improving the appearance quality of the steel structure and enhancing the anti-corrosion effect.
