Plane gate groove repairing device

The utility model discloses a plane gate groove repairing device, and belongs to the technical field of water conservancy and hydropower engineering. The plane gate groove repairing device comprises a track structure, a support and a positioning bearing structure; the two ends of the support are installed in the track structure and the positioning bearing structure respectively, a feeding device, a motor and a transmission are installed on the support, the output end of the motor is connected with the input end of the transmission, a grinding wheel is installed at the output end of the transmission, the feeding device is installed in the support, and the top end of the feeding device is connected with the motor and the transmission. According to the technical scheme, the motor and the transmission drive the grinding wheel to conduct grinding repairing on a damaged plane gate lateral water seal seat plate and a damaged main rail surface steel plate; meanwhile, the grinding wheel is controlled through the track structure and the positioning bearing structure to move in the vertical direction; the feeding amount of the grinding wheel is controlled through the feeding device, so that operation is simple, the maintaining and repairing work efficiency is improved, the manual labor intensity is reduced, a repaired gate groove is in close cooperation with a gate, and therefore the good water stopping effect is achieved.
