[0025] This scheme has the following working process: when rust and burrs appear on the surface of steel structures such as steel plates, the staff needs to grind the surface of the steel plates with a handheld grinder, which is laborious to operate for a long time. Then, the steel plates are grinded with grinding rollers to improve the grinding efficiency. However, it is difficult for the grinding rollers to grind both sides of the steel plates, and it is not easy to adjust the grinding rollers according to steel plates of different thicknesses, which limits the grinding range and reduces the practicality of the grinding device.
