Maintenance device for flange plate of in-situ cast-in-situ box girder

The utility model belongs to the technical field of buildings, and particularly relates to an in-situ cast-in-place box girder flange plate maintenance device which comprises a vehicle body, a plurality of magnetic attraction wheels are arranged on the two sides of the bottom of the vehicle body, and the magnetic attraction wheels are driven by a power mechanism. Spraying pipes are further arranged on the two sides of the vehicle body and provided with a plurality of sprayers. The in-situ cast-in-place box girder flange plate maintenance device can be adsorbed to a supporting system left after cast-in-place of a box girder is completed, water spraying maintenance and observation of the outer surface of a structure are carried out forwards, and whether the structure is damaged or not is found in time, so that the hydration effect of a flange plate is strengthened in a targeted mode, the strength of the flange plate is enhanced, and the service life of the flange plate is prolonged. And the method has good soci
