- an adapter 21 interconnecting the upper ends of the drill tubes with the drifter.
- the feed beam 3 can be adjusted into different slope angles in dependence of the direction of the intended drill hole.
- the actual drilling work takes place by means of the drifter 20, which transmits percussive and rotation power via the adapter 21 to the drill tubes.
- the drifter is moved along the feed beam for example by means of chains.
- the handling equipment according to the invention will be described in its rest position in which the feed beam is horizontal and the directions will be defined in view thereof. It is noted that the feed beam during operation is adjusted to the desired angle in relation to the ground for the intended drill hole and that the entire equipment according to the invention follows such movement. Said angle can be adjusted normally between 0° - 100° in relation to the horizontal plane.
- the handling equipment comprises two transverse support beams 1 attached to the bottom side of the feed beam 3 and extending beside the feed beam.
- Two longitudinal guide beams 2 are attached to the transverse support beams 1 parallel with the feed beam.
- the guide beams 2 are interconnected by several transverse members 16, 18, 26, which are described in more details below.
- a cradle 4 is moveable along the guide beams 2 and parallel with the feed beam.
- a first hydraulic cylinder 5 is connected between the cradle and on transverse support beam 1 for moving the cradle along the guide beams.
- the cradle 4 is shown in more details in Fig. 2 which is a side view, however with a shear-type gripper 14 (to be described below) removed.
- the transverse support beam 1, the longitudinal guide beams 2 and the feed beam 3 are shown by broken lines in Fig. 2.
- the cradle 4 comprises two longitudinal box members 27, 28 interconnected by two transverse beams 29, 30, one of which is shown in Fig. 2.
- the longitudinal box members 27, 28 encloses the guide beams 2 and are moveable along the guide beams.
- a pillar 6 Attached to one longitudinal box member 28 is a pillar 6, which extends vertically upwards from the cradle.
- the pillar is constructed of two box girders extending telescopically inside each other.
- the inner box girder is extendable out from the outer box girder by means of an internal second hydraulic cylinder 7.
- a boom 8 is mounted to the upper end of the inner box girder of the pillar 6, and extends horizontally and perpendicular towards the feed beam.
- the boom 8 is also constructed of two box girders telescopically extending inside each other and the relative movement takes place by means of a third hydraulic cylinder 9.
- a grip claw 10 pivotable around an articulated bolt 11 by means of a fourth hydraulic cylinder 12.
- the plate 13 is attached to the moveable part of the boom 8 and extends in parallel with the feed beam 3.
- the grip claw 10 is adapted, in cooperation with said elongated plate 13, to grip and hold stationary a drill tube with different diameter normally within the interval of between 38 and 133 mm.
- the grip claw 10 urges the drill tubes against the elongated plate 13 thereby maintaining the drill tube parallel with the feed beam.
- a rod 23 extending horizontally and parallel with the feed beam 3, c.f. also Fig. 1.
- the rod 23 is telescopically extendable in the axial direction by means of a fifth hydraulic cylinder 25 and is constructed of two box girders telescopically extending inside each other.
- a shear-type gripper 14 At the free end of the rod 23 is mounted a shear-type gripper 14 with a pertaining sixth hydraulic cylinder 15.
- the shear-type is shown in more details in Fig. 5.
- the shear-type gripper is positioned at a distance from the grip claw 10 and the distance is adjustable by the rod 23 by means of the hydraulic cylinder 25.
- transverse members at fixed positions along the guide beams 2.
- Two such transverse members are constructed as magazine members 16 and one such magazine member is shown in more details in Fig. 3.
- the magazine member comprises a transverse beam 16 and four vertical U-beams 31 spaced apart in the transverse direction by a distance so that outer drill tubes 33 can be placed in the space between two adjacent U-beams 31.
- two compartments 32 for outer drill tubes each housing a maximum of four outer drill tubes.
- Each outer drill tube encloses an inner drill tube 34 as described in more details below.
- the drill tubes are retained by means of plate springs 17 or spring loaded holders 24 so that they cannot fall out from the magazine at vertical or so called negative drilling when the feed beam 3 is vertical or slopes more than 90° in relation to the horizontal.
- the magazine members 16 are placed at a distance from each other corresponding to the length of the outer drill tubes.
- each magazine member is positioned 0,2 - 0,4 meters from the end of the outer drill tubes, so that the distance between the magazine members 16 is as large as possible.
- the magazine members 16 are preferably welded to the guide beams 2, but it is possible to have one (or several) of the magazine member 16 (the upper) adjustable or replaceable for adoption to drill tubes of different lengths and diameters.
- each inner drill tube is provided with a jointing sleeve 35 comprising screw windings for connection to a lower inner drill tube in the drill hole.
- Said jointing sleeve 35 forms an enlargement of the upper end of each inner drill tube.
- Said spacing member 18 comprises several vertical rods 36 as shown in Fig. 4 spaced apart for engagement below the enlargement of the jointing sleeves 35 for preventing the inner drill tubes to enter inside the outer drill tubes.
- each inner drill tube extends out from or to the left of the outer drill tube as shown in Fig. 1.
- the outer drill tubes are placed between the magazine members 16 and the inner drill tubes are placed inside the outer drill tubes and hang in the space member 18.
- the inner drill tubes are placed manually in the outer drill tubes or the shear-type gripper is used as described more closely below.
- the first outer drill tube and the first inner drill tube are each provided with drill tips, normally with tungsten carbide tips, but other constructions can also be used together with the invention.
- all hydraulic cylinders 5,7,9,12,15 and 25 can be activated.
- the shear-type gripper 14 is adjusted, in its open position, over the first inner drill tube 34, immediately below its jointing sleeve 35 between the space member 18 and the magazine members 16.
- the open grip claw 10 is at the same time positioned over the corresponding outer drill tube 33 and approximately at its longitudinal middle point.
- the boom 8 and the upper part of the pillar 6 are now adjusted and moved against the drill tubes so that the plate 13 will be placed firmly against the outer side of the outer drill tube.
- both the grip claw 10 and the shear-type gripper 14 is activated by means of respective hydraulic cylinders, whereby both the inner drill tube and the outer drill tube are captured in a position parallel with the feed beam 3.
- the captured drill tubes can be moved into the drilling centre position above the feed beam 3 and down through the drill tube guidings 19, 22 at the lower end of the feed beam.
- the drifter 20 By means of the drifter 20, first the inner drill tube is screwed to the adapter, whereupon the shear-type gripper 14 is opened. Then, the outer drill tube is screwed to the adapter, whereupon the grip claw 10 is opened. Both drill tubes are now connected to the adapter. At continued rotation of the adapter, the inner and outer drill tubes are screwed to the upper ends of corresponding drill tubes already placed in the drill hole guided by the drill tube guidings 19,22.
- Both drill tubes are now connected to the drifter and the drilling starts.
- the drill tubes are screwed off from the adapter by means of the drifter and a drill tube releaser 22 of known construction at the lower end of the feed beam.
- the drifter is moved to its upper position, whereupon a new length of outer and inner drill tubes are screwed on the drill tubes already inside the drill hole and so on.
- an inner drill tube 34 can be placed in position inside an outer drill tube 33 already placed in the magazine space 32 in the following way.
- the inner drill tube is positioned in the space 37 to the left in Fig. 3.
- the cradle 4 is moved to the far right in Fig. 1 and the shear-type gripper is withdrawn as far as possible towards the cradle 4.
- the shear-type gripper will be positioned at the middle of the inner drill tube and one such drill tube is gripped and lifted from the magazine.
- the cradle 4 is moved to the left in Fig.
- the inner drill tubes will be positioned to the left of the mouth of the outer drill tube positioned in the magazine and can be fed inside the outer drill tube by operating the pillar, the boom, the rod 23 and the cradle 4.
- the inner drill tube can of course only be moved inside the outer drill tube to the half length thereof, but the continued movement takes place either with the gravitational force if the feed beam is sloping or by gripping the outer drill tube by the shear-type gripper at a position further out.
- Fig. 6 corresponds to Fig. 1.
- the drill tubes are reversed so that the enlarged jointing sleeve 35 is positioned downwards, to the right in Fig. 6.
- the direction of the shear-type gripper 14 is reversed.
- the spacing member is replaced by a stop member 38 preventing the outer drill tubes 33 to reach the abutment plate 26.
- the inner drill tubes 34 extend through the outer drill tubes and extend beyond the stop member 38 until the abutment plate 26.
- the inner drill tubes 33 can be gripped by the shear-type gripper 14 below the outer drill tubes 33.
- the adapter must be replaced by an alternative adapter, in which the screw windings cooperating with the inner drill tubes are made as inner windings in a hole 39 of the adapter. This construction is more rugged. In all other respects the same construction is used.
- the above constructions can also be further modified.
- One possibility is to provide the pillar 6 with a possibility to rotate around a vertical axis, so that the rod 23 can be adjusted so that it is always parallel with the feed beam.
- an inner drill tube is gripped by the grip claw 10 and placed in position at the feed beam.
- the inner drill tube is connected to the adapter and screwed to the inner drill tube already in the hole.
- the adapter is disengaged from the inner drill tube and the drifter and adapter is withdrawn to the left as much as possible.
- an outer drill tube positioned in the space 37 is gripped by the grip claw 10 and moved to a position so that it can be placed outside the inner drill tube already present at the feed beam.
- the adapter again engages the upper end of the outer and inner drill tubes and the outer drill tube is at the same time screwed to the outer drill tube already in the hole.
- the drilling machine is now ready for continued work. It is obvious that the drifter and adapter must be moveable the double distance of the length of each of the drill tubes in this case. It is also obvious that an outer drill tube can be mounted before an inner drill tube. The shear-type gripper 14 is not used and can be removed if the equipment is to be used exclusively according to this method.
- valves to the hydraulic cylinders can be operated by a microprocessor in a certain sequence, which corresponds to a normal handling sequence.
- the operator can monitor the operation of the device and can intervene if necessary.
