TUNNEL CRAWLER DRILL MACHINE

A drawler drill for a tunnel is provided to have excellent mobility by reducing the volume of a drill, to perform drill work smoothly by moving only once to the wanted location, to perform drill work freely by rotating a boom of a drill in a 360-degree arc. and regulating the angle of a boom unit below a horizontal angle, and to remove dust and waste by sending out hydraulic pressure and pneumatic pressure through the existing air hose in order. A drawler drill(100) for a tunnel comprises a shifter unit(E) moving to a job site using a caterpillar, a lower body outrigger unit(F) formed on the top of the shifter unit fixing a drill to the ground, a column support unit(A) formed on the top of the shifter unit to rotate a cabin and a boom unit in a 360-degree arc. by a turntable(43) to face the front of a drill work correspondingly to the direction of a drill work and to regulate the angle of a boom unit in the vertical and horizontal directions at drill work, a boom unit(B) connected to the upper part of the column support unit and sliding by the height of drill work to regulate the height of a drilling unit and to rotate a drilling unit in a 360-degree arc. simultaneously, and to regulate the angle vertically and horizontally, a drilling unit(C) connected with the boom unit to be bent below a horizontal angle at drill work and rotating in a 360-degree arc. to perform drill work, a shank unit located at the front of the drilling unit to supply hydraulic pressure and pneumatic pressure together with a drift at drill work, and a cabin(D) regulating the drilling unit.
