Abstract
A loader for drilling machines includes a loader arm and a gripping unit for handling a drill rod. The loader arm is hinged to the frame of the drilling machine and rotates around a first rotation axis and is provided with a parallelogram structure, on which the gripping unit is mounted, so that said loader arm can move the gripping unit with a rotary motion around the first rotation axis and with a translation motion along a direction orthogonal to the second rotation axis.
Claims10
A loader for a drilling machine (100), comprising:
- a storage compartment (130) having a plurality of rods (A′), all oriented in a same direction (Y), stacked therein;
- and
- a loader arm (200) configured to handle a drill rod (A) and move the drill rod from at least one picking position (P) to a loading position (C), in which the drill rod is coupled with the a drill head (120) of the drilling machine,
- wherein said loader arm (200) comprises a gripping unit (500) configured to grip the drill rod (A),
- wherein said loader arm (200) is configured to be hinged to a frame of said drilling machine (100) and rotates around a first rotation axis (X1) orthogonal to said same direction (Y), according to which said rods (A′) are oriented in the storage compartment (130), and
- wherein said loader arm (200) comprises a parallelogram structure (400), on which said gripping unit (500) is mounted and which comprises at least one arm, or positioning arm (410), rotating around a second rotation axis (Y2) orthogonal to said first rotation axis (X1);
- so that said loader arm (200) moves said gripping unit (500):
- with a rotary motion around said first rotation axis (X1), through a rotation of said loader arm (200) around said first rotation axis (X1), between said at least one picking position (P), in which said gripping unit (500) can pick up the drill rod (A) from an inside of said storage compartment (130), and a loading position, in which said gripping unit (500) is positioned in such a way that the drill rod (A) is parallel to a drilling axis (120x), aligned with the drill head (120) of the drilling machine, whatever an inclination of said drilling axis (120x) with respect to a ground;
- with a translation motion along a direction (W) that is orthogonal to said second rotation axis (Y2) and transverse to said direction (Y) according to which said rods (A′) are oriented in the storage compartment (130), through the rotation of said positioning arm
(410) of the parallelogram structure (400);
- or
- around said second rotation axis (Y2), so that said gripping unit (500) can selectively pick up any drill rod (A) placed in the storage compartment (130) and bring said drill rod (A) to a position in which said drill rod is aligned with said drilling axis (120x).
(410) results in a corresponding translation of said gripping unit (500) in the direction (W) orthogonal to said second rotation axis (Y2).
