Abstract

PURPOSE: To easily perform drilling for a work of large size in the above described drilling machine used for drilling the work of large size such as a bridge or the like, by vertically moving a bed with a cylinder device and changing height of the bed to prescribed dimension.
CONSTITUTION: Four columns 11 are vertically provided on a saddle 2 moved on a rail 4 by wheels 3, and the longitudinally placed columns 11 are connected by a top beam 12 respectively. A bed 1 turnably supporting an arm 9 is slidably guided by the columns 11 and vertically moved by an elevation oil hydraulic cylinder 13 within a certain range. The bed 1 is moved to required height and then fixed by placing a spacer between the bed 1 and the saddle 2 or by directly clamping the bed 1 to the column 11. A main spindle head 7 equipped with a main spindle 8 is slidably provided in the arm 9.
