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. |

PROBLEM TO BE SOLVED: To improve striking efficiency by cushioning reflected energy from a shank rod with oil pressure so as to reduce damage, and advancing a bit so as to be in contact with a rock-bed to strike even in the case of a rock drill body failing to advance into a specified position by the next striking time after once retreating due to the thrust shortage of the rock drill body.
SOLUTION: A rock drill is provided with striking mechanism for striking a shank rod 2, and a chuck driver bush 13 for transmitting thrust to the crushed object side to the shank rod 2. In this rock drill, a front damping piston 4 smaller in thrust than a rock drill body 1, and a rear damping piston 5 larger in thrust than the rock drill body 1 are disposed behind the chuck driver bush 13.

PURPOSE: To more easily and inexpensively assemble a drilling device by further simplifying the handling of a junction part.
CONSTITUTION: A hole is drilled by a drilling rod consisting of a junction part 13 being driven by a rotary and/or percussive drive 7 of a drilling device 1. The wall of the borehole is supported by a casing pipe consisting of the junction part 17 being driven by a driving device 8. The junction parts 13 and 17 are mechanically taken out of a magazine and are returned into a hole after the hole is drilled. The junction part 13 and the junction part 17 are received from magazines 12 and 16 by the driving devices 6 and 8, respectively. Also, each junction part for a drilling rod and each junction part for the casing pipe are returned to the magazine.

PURPOSE: To effectively damp a repulsion from a set of rods by providing a first and second chambers and a piston communicating with an accumulator in a mechanical housing, transmitting a force determined by a pressure inside the first chamber to the set of rods, and moving the rods to the second chamber so as to seal liquid in that chamber.
CONSTITUTION: Provided are a set of pipes for transmitting a rotation to a drill bit and a set of rods disposed at the center of the set of pipes so as to transmit an impact energy from a hammer piston 4, which is moved longitudinally in an air tube housing 3, to a drill. In addition, a first chamber 5 and a second chamber 7 communicating with an accumulator 5 and a piston 8 are provided in the housing, a force determined by a pressure inside the first chamber 5 is transmitted to the set of rods, and the set of rods are moved into the second chamber to which the rods are tightly fitted so as to seal liquid in order to damp a repulsion from the set of rods.

PURPOSE: To feed enough coolant to a cut blade by energizing a turbine rotor partially in the axial direction by liquid stream, activating a collection nozzle, which is arranged at an outlet of the rotor to collect the liquid stream after deflection of this stream, as a mixing passage for sucking air and residual water from a turbine casing.
CONSTITUTION: A rotor 20 is energized axially by a liquid stream 25 from a nozzle 24, and this stream 25 hits a rotor blade 21 as a vector characterized by a tangential direction component from 80% to 96%, an axial direction component from 20% to 40%, and radial direction component from 0% to 15%, and goes out from the rotor blade 21 with having the tangential direction component, the axial direction component, and the radial direction component. A collection nozzle 26 for collecting the stream 25 after deflection of this stream 25 is arranged at an outlet of the rotor 20, and functions as a mixing passage for sucking air and residual water from a turbine casing.
