Steel structure bridge workshop primer rapid grinding device

The invention belongs to the technical field of steel structure bridge construction, and relates to a steel structure bridge workshop primer rapid grinding device, which comprises a power device, a transmission device and a grinding device, wherein the power device is connected with the transmission device to drive the grinding device, and the grinding device completes grinding and polishing. Weld joints of stiffening ribs of steel bridge top and bottom plate unit pieces are prone to fatigue cracks due to dynamic loads, so that in order to guarantee the welding quality of the stiffening ribs and the weld joints of the top and bottom plates, the weld joints of the stiffening ribs of the top and bottom plates need to be polished in advance to have metal luster, the distance between the stiffening ribs in the plate unit pieces is generally small, and the weld joints are dense, in the prior art, a traditional manual grinding wheel angle grinder wastes time and labor during grinding, and serious pollution can be generated. The steel structure bridge workshop primer rapid grinding device provided by the invention has the beneficial effects that the labor efficiency is improved, the labor cost is saved, meanwhile, pollution is reduced, the construction period is greatly shortened, and a good foundation is laid for engineering green construction, quality improvement and efficiency improvement.
