Definitions
- the present invention relates to a drill rig for drilling in for instance rock. More specifically the invention concerns a drill rig provided with means which allows drilling in an angular interval round about the vertical direction as well as horisontal drilling without modification of the drill rig.
- the present invention which is defined in the subsequent claim, aims at achieving a drill rig where drilling can occur within the above mentioned angle interval without modification of the drill rig. Through this a quicker handling is obtained since the drill rig can be adjusted between the different angle regions without repinning. One obtains better safety since the risks with repinning are eliminated. Furthermore service is simplified because one can easily position the feed device in horizontal position at a suitable height above the ground.
- fig 1 shows a drill rig according to the invention.
- Fig 2 shows a part of the drill rig seen from the left in fig 1.
- Fig 3 shows a part of the drill rig seen from the left in fig 2.
- Fig 4 is a view corresponding to fig 2 in another angle position.
- Fig 5 is a view corresponding to fig 2 in a further angle position.
- the drill rig shown in the drawings comprises a carrier 1, a boom 2 which is swingably connected with the carrier.
- the boom can be raised or lowered by means of a hydraulic cylinder 21.
- the boom 2 is at its front end provided with a boom head 22.
- the boom head is connected with the boom 2 through a joint and is swung in the plane of the figure by means of the hydraulic cylinder 23.
- a feed device 3 is pivotably connected with the boom in a way to be described below. At this rotation the feed device 3 swings in a plane perpendicular to fig 1.
- a rock drilling machine 4 is in a usual way movable to-and-fro along the feed device.
- the feed device comprises in the shown example a feed holder 33 and a feed beam 3. If desired the feed holder can be omitted.
- the feed holder 33 is tumable about an axis of rotation 10 by means of a rotation device comprising a hydraulic cylinder 5, a first link 8 and a second link 9.
- the axis of rotation 10 is arranged on the boom head 22 and thus on the boom 2.
- One end 6 of the hydraulic cylinder 5 is connected with the feed holder 33 through a joint.
- the other end 7 is by means of a joint 42 articulated to the first link 8.
- the first link 8 is furthermore by means of a joint 41 articulated to the feed holder 33 and by means of a joint 43 articulated to a second link 9.
- the second link 9 is by means of a joint 44 articulated to an ear 24 on the boom head 22 and thus connected with the boom 2.
- the feed holder 33 is shown swung out in a first direction 11 relative to a vertical line 12.
- the angle A is at least 30°.
- the feed holder 33 is shown swung out in a second direction 14 relative to the vertical line 12.
- the piston rod 13 of the hydraulic cylinder 5 is in its innermost position in the hydraulic cylinder 5, i.e. in a second end position, the feed holder is swung out at least to horizontal position, i.e. the angle B is at least 90°

Abstract
Description
Claims (1)
- Drill rig comprising a carrier (1), a boom (2) swingably connected with the carrier, a feed device (3) by means of a rotation device rotatably connected with the boom and a rock drilling machine movable to-and-fro along the feed device, characterized in that said rotation device comprises a hydraulic cylinder (5), that one end (6) of said hydraulic cylinder is rotatably connected with said feed device (3), that the other end (7) of said hydraulic cylinder is rotatably connected with a first link (8), that said first link (8) is rotatably connected with said fed device (3) and with a second link (9), that said second link (9) furthermore is rotatably connected with said boom (2), that said feed device (3) is turned about an axis of rotation (10) on the boom at least 30° in a first direction (11) relative to a vertical line (12) when a piston rod (13) in said hydraulic cylinder (5) is moved to a first end position and that said feed device (3) is turned about said axis of rotation (10) at least to horizontal position in a second direction (14) relative to said vertical line (12) when said piston rod (13) in said hydraulic cylinder (5) is moved to a second end position.
