Abstract
A method of and a device for guiding a wire in the wire bolting of a rock, wherein the wire is passed by means of a feeding mechanism from a wire magazine into a guide head supported by a feeding beam of the drilling equipment therethrough into a hole drilled in the rock. In order to protect the feeding mechanism against damage and dirt and in order to lighten the feeding beam, the wire is pushed into the guide head through a flexible guide pipe in such a manner that the feeding mechanism can be mounted on a carrier.

A method of guiding a wire for rock bolting of a rock comprising the steps of:
- feeding said wire from a wire magazine on a carrier through a single feeding mechanism;
- passing said wire from said feeding mechanism through a flexible, nonpowered guide pipe;
- moving said wire from said guide pipe into a guide head, said guide head being supported on a feeding beam mounted on said carrier;
- and
- inserting said wire from said guide head into a hole in said rock;
- said feeding, passing, moving and inserting being powered solely by said feeding mechanim.
3 more elements
Wire bolting equipment comprising:
- a carrier;
- a wire magazine mounted on said carrier;
- a feeding mechansim mounted on said carrier for withdrawing wire from said wire magazine;
- a feeding beam having drilling equipment mounted thereon, said feeding beam being pivotably on said carrier;
- a guide head supported on said feeding beam, said guide head guiding said wire into a drill hole in rock;
- and
- a flexible guide pipe extending between said guide head and said feeding mechanism, said pipe guiding said wire from said feeding mechanism to said guide head and said pipe being capable of flexing in response to pivoting of said feeding beam relative to said carrier.
