Control device for zinc plating thickness of steel structural member

The utility model relates to the technical field of steel part galvanization processing, in particular to a steel structural part galvanization thickness control device which comprises a galvanization pool, fixing frames are installed on the left side and the right side of the top of the galvanization pool, folding type supports are arranged at the left end and the right end of the top of the inner side of each fixing frame, and electric winches are installed in the folding type supports. A steel wire rope is wound inside the electric capstan, the bottom end of the steel wire rope is connected with hoisting hooks, a steel pipe fitting is arranged between the two groups of hoisting hooks in a hoisting mode, and a fixed cross rod is arranged at the top of the inner side of the fixed frame. The coating thickness of a steel part taken out after being just soaked in a galvanizing solution can be measured in a lossless mode through a magnetic induction method, whether the plane thickness is consistent or not can be
