Abstract:
A taphole drilling machine to serve two tapholes comprising:a supporting structure, a mount, a height adjusting mechanism and a vertical tilting device;wherein said height adjusting mechanism includes:a frame supported by said supporting structure,a first pressure cylinder with an integrated stroke limiting device with two independently adjustable strokes;a first supporting joint connecting said height adjusting mechanism to said mount and a first connection joint connecting said height adjusting mechanism to said tilting device;and is designed in such a way that a stroke of said first pressure cylinder produces a positively guided translation of said first supporting joint and said first connection joint in relation to said frame, so that a connecting line through said first supporting joint and said first connection joint remains parallel with itself during this movement;wherein said vertical tilting device includes:a second pressure cylinder with an integrated stroke limiting device with two independently adjustable strokes; anda second supporting joint, connecting said tilting device to said mount; andand is designed in such a way that the distance between said first connection joint and said second supporting joint is adjustable by a stroke of said pressure cylinder.
