Abstract
A method and a rod magazine for handling elongated rods in a rock drilling unit, and a bolting unit. Elongated rods, such as drill rods and rock bolts, are stored into a linear rod magazine—provided with feed members for transferring the rods upward and downward in the magazine. The feed members comprise screw surfaces 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 center, and vice versa. The transfer means are provided with gripping means for gripping the rods.
Claims29
A method for handling rods in a rock drilling rig, the method comprising the steps of:
- storing elongated rods into a linear rod magazine, in which the rods are supported parallel to each other, side by side, and at a distance from one another,
- moving the rods with a feed member in the rod magazine, and
- moving a rod that is in the rod magazine by means of transfer members to a pre-determined centre parallel to the rods, or, correspondingly, from the centre into the rod magazine,
- using a feed member provided with a screw surface for moving the rods in the rod magazine,
- preventing the displacement of the rods from contact with the screw surface,
- supporting the rods with the screw surface, and
- rotating the feed member about its rotation axis, the rods thus moving in the rod magazine towards a feed station located at an outermost end thereof or away from the feed station, depending on the direction of rotation, due to the influence of the screw surface,
- wherein the feed member in the rod magazine is tilted in relation to the rods to be handled on a plane parallel to the longitudinal axes of the rods.

A linear rod magazine for a rock drilling rig, comprising:
- at least one feed member arranged to support a plural number of rods parallel to each other, side by side, and to move them in the rod magazine, and
- transfer means for moving a rod that is at the feed station of the rod magazine to a predetermined centre that is parallel with the rods and, correspondingly, from the centre to the feed station,
- wherein
- the feed member comprises a screw surface that supports the rods in the rod magazine,
- the rods are supported by at least one transverse support on the side facing away from the feed member, which prevents the displacement of the rods from contact with the screw surface, and
- the feed member is rotatable about its rotation axis, whereby the rods move in the rod magazine towards the feed station or away from it, depending on the direction of rotation, due to the influence of the screw surface, and
- wherein the feed member in the rod magazine is tilted in relation to the rods to be handled on a plane parallel to the longitudinal axes of the rods.

A rock drilling unit comprising:
- a feed beam,
- a rock drilling machine to which a tool comprising a plural number of detachably interconnected drill rods may be coupled,
- a feeding device for moving the rock drilling machine on the feed beam, and
- a linear rod magazine for storing and handling drill rods, the rod magazine comprising at least one feed member for keeping a plural number of drill rods parallel to each other, side by side, and for moving them in the rod magazine, and, further, transfer means for transferring a drill rod located at the feed station of the rod magazine to the centre of the drill line and, correspondingly, from the centre to the feed station,
- wherein
- the feed member of the rod magazine comprises a screw surface by which the drill rods are arranged to be transferred, and
- the feed member is rotatable about its rotation axis, whereby the rods are arranged to move in the rod magazine towards the feed station or away from it, depending on the direction of rotation, due to the influence of the screw surface, and
- wherein the feed member in the rod magazine is tilted in relation to the rods to be handled on a plane parallel to the longitudinal axes of the rods.

- a feed beam;
- a bolting device that allows a rock bolt to be arranged into a drill hole drilled in advance, and
- a linear rod magazine for storing and handling rock bolts, the rod magazine comprising at least one feed member for holding a plural number of rock bolts parallel to each other, side by side, and for moving them in the rod magazine, and, further, transfer means for transferring a rock bolt located at the feed station of the rod magazine to the centre of the bolting line and, correspondingly, from the centre to the feed station,
- wherein
- the feed member of the rod magazine comprises a screw surface by which the rock bolts are arranged to be transferred, and
- the feed member is rotatable about its rotation axis, whereby the rock bolts are arranged to move in the rod magazine towards the feed station or away from it, depending on the direction of rotation, due to the influence of the screw surface, and
- wherein the feed member in the rod magazine is tilted in relation to the rods to be handled on a plane parallel to the longitudinal axes of the rods.
