Abstract
A rock drilling device comprising a feed beam (4), which has a drill end (41) from which the drill point protrudes at drilling and a rear end(42) opposite the drill end; a rock drilling machine (5) movable along the feed beam (4); a pressure cylinder (6), which is arranged in connection with the feed beam (4) with one end (622) movable relative to the feed beam (4) and one end (611) fixedly arranged relative to the feed beam (4). The pressure cylinder (6) drives a feed line (51) for feeding the drilling machine (5) to and fro along the feed beam (4). The feed line (51) is routed over two outer sheaves (52, 53) that are arranged at each end (41, 42) of the feed beam (4) and a measuring device (7) for measuring the location of the drilling machine (5) relative to the feed beam (4) is arranged to the shaft (9) of one of the sheaves (52, 53) and the sheave and the shaft (9) are arranged such that they rotate together.
