Fabricated steel structure polishing device

The utility model belongs to the technical field of assembly type steel structure buildings, and discloses an assembly type steel structure polishing device which comprises a channel steel body and a polishing mechanism, the polishing mechanism comprises a motor and a polishing wheel disc, and the back face of the polishing mechanism is connected with a fixing mechanism capable of limiting the moving range of the polishing mechanism in a sliding mode. A groove is formed in the side, close to the grinding mechanism, of the fixing mechanism, a cleaning mechanism capable of cleaning residual chippings on the upper surface of the channel steel body is detachably connected into the groove of the fixing mechanism, the lower surface of the cleaning mechanism abuts against the upper surface of the channel steel body, and a pushing mechanism is installed on the front face of the fixing mechanism. And the moving position of the grinding mechanism is limited through the fixing mechanism, so that the situation that the g
