The invention relates to a method and a rod magazine for handling elongated rods in a rock drilling unit, and to a bolting unit. Elongated rods (9), such as drill rods and rock bolts, are stored into a linear rod magazine (13) provided with feed members (19) for transferring the rods upward and downward in the magazine. The feed members (19) comprise screw surfaces (25) by which the rods are supported in the magazine. The required feeding movement is produced by rotating the feed members about their rotation axis. In addition, the rod magazine comprises transfer means that allow the rods to be transferred from the magazine to a drilling line or bolting line, i.e. to a centre (K), and vice versa. The transfer means are provided with gripping means (34) for gripping the rods.
L'invention concerne un procédé et un magasin à tiges pour manipuler des tiges allongées dans une unité de forage de roche, et également une unité de boulonnage. Les tiges allongées (9), telles que des tiges de forage et des boulons d'ancrage, sont stockées dans un magasin à tiges linéaires (13) doté d'éléments d'alimentation (19) destinés à transférer les tiges vers le haut et vers le bas dans le magasin. Les éléments d'alimentation (19) comprennent des surfaces de vis (25) grâce auxquelles les tiges sont supportées dans le magasin. Le mouvement d'alimentation requis est produit par rotation des éléments d'alimentation autour de leur axe de rotation. En outre, le magasin à tiges comprend des moyens de transfert qui permettent aux tiges d'être transférées du magasin vers un câble de forage ou un câble de boulonnage, c'est-à-dire, vers un centre (K), et vice et versa. Les moyens de transfert sont dotés de moyens de préhension (34) permettant de saisir les tiges.
