Abstract

The raise reamer for mines comprises a main support in the rods to carry the roller bits, and an additional support with roller bits, for pilot and reamed hole diameters respectively. The additional support (7) is coaxial to the main support (1) and can be adjusted axially to this (1). Axial adjustment is preferably carried out using telescopic sleeves (20, 21) assisted by enclosed springs (19). The roller bits (9) on the additional support (7) lie ahead of those (5) on the main support (1) so as to take out the smaller diameter pilot hole. The additional support (7) is fitted with a ratchet locking system formed from pneumatic cylinders (14) and return sorings (15) connected to the arresters (11) and claws (16).
