Foldable or detachable feed rail for rock drill

摘要

A foldable feed rail for a rock drill is composed of two segments, a first beam defining a first rail segment and a second beam defining a second rail segment. The second beam may be pivotally connected to the first beam with a hinge to enable the second beam to be folded relative to the first beam. Alternatively, the second beam can be detachably connected to the first beam so that the second beam can be removed altogether from the first beam. This invention enables the feed rail to be shortened, thereby making the feed rail much easier to maneuver in mines.

主权项

1. A foldable feed rail for a rock drill feed system, the feed rail comprising:
a first beam forming a first channel that defines a first rail segment configured to receive a rock drill; and a second beam forming a second channel that defines a second rail segment, the first and second channels having substantially identical shapes to enable the rock drill to be fed along the first and second rail segments when the first beam is aligned with the second beam, wherein the second beam is movable between an operative position in which the second beam is aligned with the first beam and an inoperative position in which the second beam is not aligned with the first beam, wherein the second beam is pivotally connected to the first beam by a hinge to pivot relative to the first beam about a pivot axis that is substantially orthogonal to a longitudinal axis of the first beam to enable the second beam to be folded relative to the first beam.
