APPARATUS ADJUSTING HIGHT LEVEL FOR PLATE

An equipment for adjusting step heights of boards is provided to adjust step heights of the two boards without leaving any damage on surfaces of the boards before welding two boards with different height levels, and to easily adjust the step heights of the boards even when a working space under the boards is small or it is difficult to reach the working space since it is not necessary to adjust the step heights of the boards under the boards. An equipment for adjusting step heights of boards comprises: a body(10) placed on a top face of a board(2) at a higher position in two boards(2,3) with different height levels; a board ascending member(20) which is penetrated into the body such that the board ascending member is liftable and lowerable within the body, and of which a lower end is inserted between two boards and caught on a bottom edge of the board(3) at a lower position; a cylinder(30) placed on a top face of the body to forcibly ascend the board ascending member; an eccentric cam(40) rotatably installed on a front face of the body to prevent descent of the board ascending member; and a wedge member(50) which is elastically installed within the body by a spring(51) in a state that the wedge member comes into contact with a backside of the board ascending member, and which is inserted between the two boards together with a lower portion of the board ascending member.
