Abstract (en)
[origin: WO2010092236A1] The invention relates to a method for manipulating drill rods, to a centralizer and to a rock drilling unit. It is possible to introduce rods (9, 18) into the centre (K) of a rock drilling unit (4) or a bolting device by means of a changing device (13), and to remove from the centre. The rod locating in the centre is supported by a centralizer (16), through the central opening (20) of which the rod is arranged. The centralizer comprises a closing element (22) which is opened and closed in accordance with the operation of the changing device. The turning of the changing device affects a push rod (25) which releases the shape-locking of the closing element and transfers it to the open position. When the changing device is turned back to the normal position, a force member (26) returns the push rod to the normal position and simultaneously the closing element is shape-locked again. In the closed position the closing element is rigidly shape locked.
