Efficient cleaning equipment of bridge guardrail for bridge engineering

The efficient cleaning equipment for the bridge guardrail for the bridge engineering comprises two bearing bases which are symmetrically arranged and two adjusting plates which are fixedly arranged in the centers of the upper end faces of the two bearing bases respectively, and a plurality of universal wheels are movably installed at the bottoms of the two bearing bases. Through grooves allowing the threaded shaft rods to be movably arranged are formed in the middles of the interiors of the two adjusting plates, grooves allowing the motors to be fixedly installed are formed in the bottoms of the opposite sides of the two adjusting plates, and motor shafts of the two motors extend into the through grooves and are fixedly connected with the two threaded shaft rods correspondingly. Adjusting blocks are installed on the outer edge faces of the two threaded shaft rods in a threaded fit mode, the two sides of the two adjusting blocks are fixedly connected with U-shaped movable plates abutting against the two sides
