Japanese Patent JP4660044
Kind Code:
B2
Abstract:
A rock drill includes a mounting frame to which a hammering apparatus and a rotating apparatus is arranged. The mounting frame is made maneuverable with respect to a feeding beam by means of slide blocks fastened to it, whereby a separate carriage is not needed between the drill and the feeding beam. Owing to the mounting frame, the hammering apparatus and/or the rotating apparatus can be replaceable modules. The invention further relates to a mounting frame which is arranged to transmit the feed and recoil forces directed to the drill to feeding means. The mounting frame comprises a section parallel to the feeding beam, to which slide blocks are fastened, and a transverse axial support thereto, to which the hammering apparatus and the rotating apparatus are mounted.
