Definitions
- the main patent relates to a drilling device, in particular for blast hole drilling, with a mount for the feed and the pulling of the drill rod formed from individual drill rods, a feed system, a pressure-actuated drive for the drill pipe, which is located on a carriage that can be moved on the mount , as well as a hydraulically actuated in-hole hammer arranged at the front end of the drill pipe, the drive for the drill pipe transmitting a back and forth swiveling movement, preferably with a swivel angle of 180-360 degrees, and the drill rods are equipped with two longitudinal channels open to the outside for receiving hydraulic hoses for the inlet and return of the pressure oil for the in-hole hammer, as well as a blowing air line in these, and a hose threading and unthreading device is provided, which is attached to the Slide of the drive for the Boh is attached and is directly or indirectly coupled to the drive member.
- torque Transfer from the swivel drive to the drill pipe provide the drill rods with a profile, so that there is a positive connection and / or this takes place by force-locking via a clamping device.
- the feed and the pulling are done via the chain drive of the flushing head.
- a new boring bar from a boring bar magazine can be inserted.
- the drilled drill pipe located in the borehole is held in a conventional manner by a holding head. Now the slide is moved back to its upper starting position via a special drive.
- the hydraulic hoses are pressed into the longitudinal channels of the newly inserted boring bar via the threading elements of the hose threading and unthreading device, whereupon the newly inserted boring bar can be drilled out.
- the procedure is reversed, in which case the hydraulic hoses are pressed out of the boring bar to be removed by the unthreading members when the carriage is moved.
- the boring bars are designed as hollow bars, the purge air is fed through them. However, if these are made of full material, the purge air for the in-hole hammer cannot pass through the inside of the Boring bars are blown so that the & e are equipped with blowing air lines present in these.
- the invention has for its object to improve the drilling device according to the main patent in such a way that the torque transmission of the swivel drive to the drill pipe can be transmitted without a special profile of the drill pipe forming the drill pipe and / or without additional clamping devices.
- the flushing head, the hose threading and unthreading device and the drive member of the swivel drive form a drive unit which is pivotably arranged on the carriage carriage and the flushing head in the drive unit about a transverse to the longitudinal axis of the boring bars Axis can be pivoted, the flushing head having a recess in its connection area for the drill rod ends, the shape of which is adapted to that of the insertion ends of the drill rods in such a way that the torque transmission for the drill rods takes place by positive locking.
- This configuration ensures that the flushing head not only executes the movement for the feed and the pulling of the drill rod, as is conventional, but also transfers the pivoting movement of the swivel drive onto the drill rod by positive locking. wearing.
- the torque is transmitted through the conventional insertion ends of the boring bars, for example in a square or hexagonal shape, in cooperation with an appropriately designed recess in the lower region of the flushing head.
- the flushing head In the uppermost position of the drive unit, the flushing head is pivoted into its working position for connection to the upper end of the projecting boring bar, after drilling the boring bar, the flushing head is pivoted sideways away from the axis of the drill pipe, so that the drive unit can move back unhindered while simultaneously The hydraulic hoses can be threaded into the newly protruding boring bar.
- a bore running transversely to this is provided for receiving the retaining bolts at the insertion ends of the boring bars, into which they snap under spring action.
- the bore for receiving the retaining bolts extends outwards, so that from the outside the retaining bolts can be pressed back against the action of their spring and the flushing head can be released.
- the outwardly extending bore can merge into a section with an enlarged diameter.
- the swiveling movement of the flushing head is advantageously carried out with by means of a cylinder-piston unit that can be pressurized, which is included in the control of the entire workflow of the drilling device.
- the carriage is designated by 1 and can be moved on the carriage (not shown) of the drilling device.
- the pressure medium-loaded drive 2 which is designed as a swivel motor with a gear 3, is fastened to the slide 1.
- the pinion 4 of the gear 3 meshes with a toothed ring 5, which is located on the drive member 6 for the drill rods consisting of the individual drill rods 7.
- the drive member 6 forms with the flushing head 8 and the hose threading and unthreading device 9 a drive unit which is pivotably arranged on the carriage 1 of the mount of the drilling device, specifically about the longitudinal axis of the boring bars 7, which simultaneously represents the pivot axis.
- the hose threading and unthreading device 9 has a threading element 12 and a threading element 13 for each hydraulic hose 10, 11.
- the flushing head 8 can be pivoted in the drive unit about an axis 15 running transversely to the longitudinal axis of the boring bars 7, namely by means of a cylinder-piston unit 16 pressurized with pressure medium.
- the flushing head 8 has in its connection area for the drill rod ends 17 a recess 18 which is adapted in shape to that of the insertion ends 19 of the drill rods 7 in such a way that the torque transmission to the drill rods 7 takes place by positive locking.
- the insertion ends 19 can, for example, be of square or hexagonal design and correspondingly the recess 18 of the flushing head 8.
- the boring bars at their ends can be matched with shaped pieces for the rotationally fixed connection of the boring bars to one another and for alignment Connection of the longitudinal channels of the same are provided.
- the retaining bolts 21 are under the action of a spring and thus automatically engage the bore 20 a.
- the bore 20 extends outwards preferably over a section 22 with an enlarged diameter, so that the retaining bolts 21 of the insertion ends 19 of the drill rods 7 can be pushed back to release the flushing head 8.
- the flushing head 8 In the position shown in the drawing, the flushing head 8 is placed with its recess 18 on the insertion end 19 of a drill rod 7, which is provided from a magazine (not shown further), the retaining bolt 21 of the insertion end 19 snapping into the bore 20 of the flushing head 8 is.
- the flushing air is supplied to the flushing head 8 via the flushing agent hose 23.
- the drill rod can now be drilled out, the feed being applied to the carriage 7 via the usual chain feed.
- the drill pipe is held in a manner known per se by a holding head.
- the retaining bolt 21 is loosened, the carriage 1 is moved upwards and, after the insertion end 19 has been released, is actuated by actuating the cylinder-piston unit 16 into the pivoted-out position shown in dash-dot lines in the drawing.
- the next boring bar 7 is placed in front and the boring bar end 17 of the drill pipe is inserted into the boring bar end with the recess of the next above boring bar, the retaining bolt 21 engaging in a corresponding bore in the recess of the boring bar end, in the same way as in the bores 20 of the flushing head 8.
- the flushing head 8 In the uppermost position of the drive unit, the flushing head 8 is pivoted back into its working position shown in the drawing and connected to the drill rod end 19, so that the next drill rod 7 protruding can be drilled in the same way.
