Embodiment Construction

[0075] figure 1 A rock drilling machine 1 is shown comprising a movable carriage 2 , one or more drilling arms 3 and a drilling unit 4 arranged in the drilling arms 3 . The drilling unit 4 comprises a feed beam 5 on which a rock drilling machine 6 can be moved by means of feed means 7 . Furthermore, the drilling unit 4 comprises a drilling tool 8 with which the impact pulses generated by the impact device of the rock drilling machine 6 are transmitted to the rock to be drilled. The rock drilling machine 6 is also provided with rotating means for moving the drilling tool 8 around its longitudinal axis during drilling. As indicated by the arrow and reference T, the turning device is controlled to repeatedly reverse the direction of movement of the drilling tool. It should be mentioned that in some drilling techniques it is possible to perform drilling without providing a drilling tool with percussion pulses, so then the rock drilling machine 6 does not have any percussion mean...

Abstract

The invention relates to an apparatus, a rock drilling rig and a method for rock drilling. The device comprises a turning device (TD) for moving a drilling tool (8) around its longitudinal axis. The rotational movement (T) is controlled by means of an alternating rotational system (ATS) such that the direction of the rotational movement is continuously reversed to the first rotational direction and the second rotational direction. The angle of rotation of the drilling tool is limited and a safety system (SS) is configured to monitor the operation and ensure that a predetermined angle of rotation is not exceeded.

Description

technical field [0001] The invention relates to a device for rock drilling. The apparatus includes a rock drilling machine and a drilling tool connectable to the rock drilling machine. The rock drilling machine comprises means for moving the drilling tool about its longitudinal axis during drilling. [0002] The invention further relates to a rock drilling machine and a method for drilling holes. Background technique [0003] In rock drilling, a borehole is drilled into rock material or into the soil by means of a rock drilling machine arranged to the rock drilling machine. Boreholes may be drilled in mines, quarries, construction sites and may be blastholes, reinforcement holes or boreholes for any other purpose. During drilling, the drilling machine rotates the drill tool about its longitudinal axis. The rotating drill string and rotating machine components of a rock drilling machine can cause entanglement and serious injury to the drilling machine. Usually, care is t...
