SIDE DOOR-DRILLING DEVICE OF A RAILWAY VEHICLE FOR ENABLING SMOOTH PROCESS OF HOLE WORK AND THE LIKE IN MOUNTING A SIDE DOOR RAIL

摘要

PURPOSE: A side door-drilling device of a railway vehicle is provided to smoothly execute hole work and the like in mounting a side door rail and to execute drilling work while moving regardless of the height. CONSTITUTION: A side door-drilling device of a railway vehicle comprises a moving trolley(10); a pair of interlocking supports(30a,30b) to which frames are combined in an X-shape by a central shaft-fixing part(39) to be supported to the upper side of the moving trolley; a lift(20) formed to the upper side of the interlocking supports; a cylindrical post part(100) having a slider(80) to move while sliding in the longitudinal direction of the side of the lift; a rotation part(70) formed to the upper side of the cylindrical port part; a right and left movement block mounted to the upper side of the rotation part; a forward and backward movement block(60) mounted to the upper side of the right and left movement block; an upward and downward movement block(40) mounted to the front of the forward and backward movement block; and a drill part(50) formed to the front of the upward and backward movement block to execute hole work to the side of the railway vehicle. The rotation part has a lever rotating in the circumferential direction. The right and left movement block moves while sliding right and left by a worm gear and a handle. The forward and backward movement block moves forward and backward by the rotation the handle and the worm gear. The upward and downward movement block moves upward and downward by the worm gear and the handle.
