Abstract
A drill column end section assembly for a drill stand, comprising an end section (110) and a feed unit stopping element (120) arranged movable between a first position and a second position, wherein the stopping element (120), when in the first position, is arranged to prevent a drill stand feed unit from traversing past the drill column end section assembly, and, when in the second position, is arranged to allow the drill stand feed unit to traverse past the drill column end section assembly. The drill column end section assembly also comprises a positioning element (130) configured to releasably hold the stopping element (120) in the first position.
Claims22
A drill column end section assembly for a drill stand, comprising an end section and a feed unit stopping element arranged movable between a first position and a second position relative to the end section, wherein the stopping element, when in the first position, is arranged to prevent a drill stand feed unit from traversing past the drill column end section, and, when in the second position, is arranged to allow the drill stand feed unit to traverse past the drill column end section, the drill column end section assembly further comprising a positioning element configured to releasably hold the stopping element in the first position.
(canceled)
A method for attaching a feed unit to a drill stand, the method comprising;
- configuring a feed unit stopping element to be movable between a first position and a second position in relation to an end section of a drill column end section assembly, wherein the stopping element, when in the first position, is arranged to prevent a drill stand feed unit from traversing past the drill column end section and, when in the second position, is arranged to allow the drill stand feed unit to traverse past the drill column end section, wherein the drill column end section comprises a positioning element configured to releasably hold the stopping element in the first position,
- moving the feed unit stopping element into the second position,
- traversing the feed unit past the end section and onto the drill column, and
- moving the feed unit stopping element into the first position, thereby preventing the feed unit from traversing past the drill column end section.
A method for removing a feed unit from a drill stand, the method comprising;
- configuring a feed unit stopping element to be movable between a first position and a second position in relation to an end section of a drill column end section assembly, wherein the stopping element, when in the first position, is arranged to prevent a drill stand feed unit from traversing past the drill column end section, and, when in the second position, is arranged to allow the drill stand feed unit to traverse past the drill column end section, wherein the drill column end section comprises a positioning element configured to releasably hold the stopping element in the first position,
- moving the feed unit stopping element into the second position, and
- traversing the feed unit past the end section and off the drill column, thereby removing the feed unit from the drill column.
A locking mechanism for locking an angle adjustment arrangement of a drill stand at a fixed angle, the locking mechanism comprising a locking bolt and a frame configured to slidably hold first and second gripping members, each gripping member comprising an angled surface configured to engage a corresponding angled surface of the frame, whereby the gripping members are arranged to grip around a respective protrusion or lath arranged longitudinally on the drill stand when pushed against the angled surface of the frame by the locking bolt.
