Abstract: Rock drilling device comprising a drilling tool with a set of tubes (7) and a set of rods (9) arranged therein. The drilling tool comprises a number of sections which each comprises a tube (7), a rod (9) and an end piece (11). The rod is provided with projections (10) at least near one of its ends for cooperation with parts (13,14) with reduced diameter in the tube and end piece respectively. The part (13) in the tube limits the movement of the rod in a direction away from the end piece. The part (14) in the end piece limits the movement of the rod in a direction towards the end piece. All thread connections (12) between different sections of the drilling tool and between tube and end piece within each section are made in the same way and thus equally easy to break.

Abstract: A rock drilling machine with a first control means (21, 22) within a second piston (6) and acting on a first piston (13) such that it counteracts displacement of the relative positions of a first and a second control device at the moment of contact of the second piston onto the drill rod or onto a part (9) connected to this. Furthermore, a rock drill rig comprising such a rock drilling machine and a method for counteracting the said displacement. Significant improvements in reproducibility for impact mechanism stability over long manufacturing series are achieved through the invention. In the same way, the lifetime of rock drilling devices manufactured according to the invention is extended through the impact mechanism acting in a more stable manner despite wear of component parts. It is furthermore possible to dimension for higher rates of impact without risking the impact mechanism stability.
