摘要： A rock drilling apparatus for drilling with high pressure hydraulic jet including a rock drill body (11), a drill tool (12) coupled to said body (11) and a feeding device (15) with a motor (16) for feeding said body and tool to and fro the working face. The drilling tool (12) has an inner rotating tube (40) with a high pressure nozzle body (41) at the nose thereof and an outer tube (42) surrounding said inner tube (40). Said outer tube (42) is provided with a hard metal collar (61) at the front end for protecting the nozzle body (41) and for calibration of the drill hole size. A sensing device including a pressure operated switch 73 and an adjustable time relay (83) is adapted for sensing the feed resistance met by said collar (61) and causing said feed motor (16) to retract said drill body (11) and tool (12) when a preset value of the resistance is exceeded.

摘要： The impact velocity and impact frequency of the hammer piston of a percussion rock drill are varied in incremental steps in order to find the maximum penetration rate. The frequency and impact velocity are so varied that the impact power is kept substantially constant all the time. A micro-computer is used to control the process.

摘要： A method and an arrangement for controlling the feeding of a rock drilling machine so that the feeding of a drill rod of the rock drilling machine is controlled on the basis of the rotation resistance of the drill rod rotated by a hydraulically operated rotation motor of the machine. In the method, the rotation resistance is determined as a pressure difference acting across the rotation motor on the basis of which the operation of the feed motor is controlled. The arrangement is characterized in that it comprises means for determining the pressure difference acting across the rotation motor and for controlling the supply of the pressure fluid to the feed motor on the basis of said pressure difference.

摘要： A method and an arrangement for controlling rock drilling on the basis of a pressure acting in a pressure conduit of a rotation motor of a drill rod. In the method, the pressure acting in the pressure fluid conduit of the rotation motor is measured during the rotation when the drill bit does not touch the rock to be drilled, and the control is carried out thereafter on the basis of the difference between the pressure value measured during the drilling and the idle pressure value. In the arrangement, the rock drilling machine comprises a control unit that measures the pressure acting in the pressure fluid conduit of the rotation motor when the drill rod is rotated so that it does not touch the rock to be drilled and stores it in the memory and controls the rock drilling machine during the drilling on the basis of the difference between the pressure value measured during the drilling and the idle pressure.
