Abstract
An arrangement for feeding soldering material into a space between a bolt and rock includes a sleeve-like nozzle which can be pushed tightly against a feed chamber on the rock bolt so that a feed hole in the feed chamber is connected to the inner space of the nozzle. The arrangement further includes a device for placing the nozzle around the feed chamber so that soldering material can be fed from the inner space of the nozzle into the drill hole.
Claims16
An arrangement for feeding soldering material into a space between a bolt and a surface of a drill hole, comprising:
- a guide tube adapted to be disposed around a bolt in a drill hole;
- a feed chamber connected to the guide tube, the feed chamber having a feed hole providing flow communication for soldering material into the feed chamber and into the drill hole through the guide tube, the feed chamber including an opening permitting the bolt to extend through the feed chamber so that the bolt can be fixed in the drill hole;
- a sleeve-shaped nozzle having a sealing surface;
- and
- means for moving the nozzle so that the sealing surface seals an outer surface of the feed chamber and so that the feed hole communicates with an inner space of the nozzle and so that soldering material can be fed from the inner space of the nozzle into the drill hole.
2 more elements
A rock bolting device, comprising:
- a bolt feeding device, the bolt feeding device comprising a clamping tool for securing a clamping member to a bolt,
- an arrangement for feeding soldering material into a space between the bolt and a surface of a drill hole, the arrangement including a guide tube adapted to be disposed around the bolt in a drill hole, a feed chamber connected to the guide tube, the feed chamber having a feed hole providing flow communication for soldering material into the feed chamber and into the drill hole through the guide tube, the feed chamber including an opening permitting the bolt to extend through the feed chamber so that the bolt can be fixed in the drill hole, a sleeve-shaped nozzle having a sealing surface, and means for moving the nozzle so that the sealing surface seals an outer surface of the feed chamber and so that the feed hole communicates with an inner space of the nozzle and so that soldering material can be fed from the inner space of the nozzle into the drill hole,
- wherein the nozzle includes an opening through which a portion of the clamping tool extends and, when the bolt feeding device feeds a bolt into a drill hole, the clamping device is adapted to secure the clamping member to the bolt at the same time that soldering material is fed into the feed chamber through the nozzle.
