Abstract

Device for raise boring comprising a rotation device (1), a drill string (2) and a reaming head (5). The reaming head (5) comprises a connection part (6) with a spring biased first body (7) which is displaceable between two end positions. The tube (3) being closest to the reaming head (5) in the drill string (2) comprises a second body (9) about which a connection means (10) is displaceable between a first position (fig 3) where the connection means (10) is unturnable relative to the second body (9) and a second position (fig 4) where the connection means (10) is turnable relative to the second body (9). Through this a safety device is achieved which prevents the reaming head (5) from falling if the joint between the reaming head (5) and the drill string (2) should break.
