The invention discloses an efficient steel plate rust removal device for a construction site. The efficient steel plate rust removal device comprises a base, support columns, a top plate, a lifting mechanism, a power device, a dust removal mechanism and a working platform. The rust removal mechanism comprises a mounting plate, horizontal plates, a vertical plate, racks, a semi-circular gear, firstthrough holes, pressure rods, threaded parts, bolts, a pressure plate and a hairbrush. Compression springs are arranged between the pressure plate and the horizontal plates below the pressure plate.Connecting rods are mounted at the upper end of a mounting frame. A sliding block is mounted at the top end of each connecting rod. Sliding grooves are formed in the lower end face of the mounting plate. The upper end of each sliding block is slidably arranged in the corresponding sliding groove.
