Abstract

A drilling machine with a chassis, a mast (4), a crown sheave (23) mounted on the end of the mast (4) or a mast extension (5) and intended for an impact rope (7), and an impact device which contains a winch, in particular a free-fall winch, arranged on the chassis or on the mast (4) for the impact rope (7) and an impact mechanism (8) carried by the mast (4) and having a motor-driven crank (16) or another mechanical motion element for an impact-mechanism sheave (14). In this drilling machine, the impact mechanism (8) is a built-in part of the mast (4) or a mast extension (5) in such a way that the range of movement of the impact-mechanism sheave (14) lies partly within the outline contour of the mast (4) or the mast extension (5). In this arrangement there is a single deflection sheave (22), arranged in the mast (4) or a mast extension (5), for the impact rope (7). The latter is run directly to the crown sheave (23) via the deflection sheave (22). <IMAGE>
