Embodiment Construction

[0043] figure 1 A rock drilling apparatus 1 is shown comprising a movable carrier 2 arranged with one or more drilling arms 3 provided with a rock drilling unit 4 . The rock drilling unit 4 comprises a rock drilling machine 5 movable along a feed beam 6 by means of a feed device 7 . The rock drilling machine 5 may have connected thereto a drilling tool 8 which may comprise a plurality of continuous drilling rods 9 connected to each other by connecting members such as screw joints. Furthermore, the outermost end of the outermost drill rod 9 is provided with a drill bit 10 having a drill button that creates a drill hole 12 into the rock 11 . The rock drilling machine 5 may comprise percussion means for supplying percussion pulses to the drilling tool 8 which transmits percussion pulses to the drill bit 10 and further to the rock 11 to be broken. The rock drilling machine 5 may also comprise rotation means allowing the drilling tool 8 to rotate about its longitudinal axis durin...

Abstract

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.

Description

technical field [0001] The present invention relates to a method of storing and handling elongated rods such as drill rods and rock bolts by means of a rod magazine arranged at the end of a drill boom. A plurality of rods are stored side by side in a linear rod magazine and moved within the rod magazine by means of one or more feed members. Depending on whether rods are being loaded into or unloaded from the magazine, the feed member moves the rods towards or away from the feed station. Then, the rod is transferred to the drilling line or bolting line, ie to the center, by means of the transfer device. During the transfer, the rod to be transferred is held by gripping members provided in the transfer device. [0002] The present invention also relates to a rod store, and to a rock drilling unit and a rock bolt support unit provided with the rod store. The field of the invention is defined in more detail in the preambles of the independent claims. Background technique [...
