- the inventive, for driving at least one BohrgestCodes serving rotary impact device has a striker and a rotary device as well as one in one Device body rotatably mounted Einsteckende, the one having axially extending bore, in which a percussion piston is mounted axially displaceable.
- the means of a Connector and preferably a rotary impact receiver The insertion end connected to the drill string is used by the Turning device and the impact piston mounted in the insertion end regardless of the impact device driven.
- the over the percussion piston on the high Torque impinged rotary impact receiver transmitted Impact energy therefore has greatly reduced effects on the according to the invention decoupled from the impact device Infectious, due to the reduced load over can be operated for a relatively long time without Material fatigue occur, which is a repair of the Make rotary impact device necessary.
- the inventive Rotary impact device therefore requires only a small Maintenance and repair costs. It also increases due to the extension of the maintenance intervals the availability of Device, resulting in a significant reduction in operating costs results.
- the invention of The impact device decoupled insertion end does not work more than sound box and isolated at the same time Vibrations of the percussion piston.
- the noise reduction leads to Relief of the staff and other persons who if necessary near the place of operation Stop device.
- the device body is preferably designed such that that therein at least two spaced-apart areas are provided, in which the example by means of a preferably a hydraulic or pneumatic rotary actuator via a toothed gear driven spigot can be stored.
- the Hiding between the areas where it is in the fixture body is stored, a stop surface on that too a holding member connected to the device body corresponds, through which the insertion in axial Direction is held and optionally attenuated.
- the Einsteckende preferably has an external toothing, in which engages a gear or one of a with a Internal ring provided ring is included, at the Scope coupling elements for the engagement of the rotating device are provided.
- a flange on the output side of the male end comprehensive part of the device body is.
- This the insertion end comprehensive side part can with a preferably hydraulic damping element with be connected to the device body, so that the Infinite with vibrations and impacts of the percussion mechanism can resonate. Indirectly transmitted to the insertion end Impact energy therefore causes no material deformations For example, on the connector, but is in Damping element absorbed.
- the retaining element e.g. a retaining ring, with a Be connected damping element.
- the insertion end and in particular that associated with the rotary impact receiver Connector is therefore not only from that of the Impact device directly emitted impact energy, the Drehtschempftuler is supplied via the percussion piston, but also indirectly from the over the turnbuckle receiver transmitted impact energy decoupled, so early Material fatigue at the junction between Infiltrating and rotary beating receivers are avoided.
- the solution according to the invention will therefore also damage the Einsteckende and avoided at the rotary impact receiver.
- the intended in the insertion end percussion piston consists preferably from a cylindrical part and a Connector or a shoulder provided therein partially protruding flange, which prevents the Impact piston by the reactions of the drill pipe axially runs back.
- the invention is also in so-called double impact can be used advantageously.
- the percussion piston and one with the Percussion piston impact hammer acting together have to axially extending holes, in those of a further rotating device and / or a another impact device driven drive means for a second, preferably within the first drill string arranged drill pipe are provided.
- the second drill pipe directly or indirectly connectable inner insertion end, preferably a rotary impact shaft, provided, the rotating and / or impacting or turning that loaded and with an axially extending bore is provided, within the one beating acted upon inner percussion piston is arranged.
- Fig. 1 shows an inventive, for driving a Drill rod serving rotary impact device 1 with a Cylinder housing or a device body 8, in which a with a spigot 3 coupled rotating device 5 and a Schlagtechnik or a percussion device 6 are provided, the with one in an axially extending bore 37 of the Plug-in 3 slidably mounted percussion piston 4 interacts.
- the insertion end 3, which is used to transfer one of the Turning 5 generated torque to one with the Drill rod connectable rotary impact receiver 2 is used, points two spaced-apart, cylindrical sections 31, 32 in the device body 8 in corresponding Areas 81, 83 are stored or covered by bearing shells.
- the percussion piston 4 has a striking device 6 facing and from a likewise piston-shaped hammer 61 acted first end piece 42, a cylindrical, in the bore 37 of the insertion end 3 mounted body 41 and a second end piece 43 which is in the form of a flange the connector 33 within the Drehtschempfnatureer 2 provided threaded hole 21 overlaps front and preferably between connector 33 and Drehtschempfnatureer 2 is held firmly. From the impact device 6 or the percussion hammer 61 delivered beats are therefore by means of the percussion piston 4 directly on the rotary impact receiver 2 transferred.
- the insertion end 3 then points to the with the Drehtschempf briefly 2 connected connector 33 a tapered flange 34, which in a further Embodiment of the invention as a stop for the rotary impact receiver 2 can serve.
- the flange 34th ring-shaped and one-sided to the insertion end 3 on the output side comprehensive part 85 of the device body 8 then arranged so that repercussions of Drill rods are transferred to the part 85.
- the part 85 is in this case via a preferably hydraulic Damping element connected to the device body 8, so that the insertion end 3 in vibration and setbacks of the Drilled pipe string can resonate.
- the rotary impact receiver 2 shown in FIG. 1, for example, for example is by means of an external thread 25 with an outer Drill pipe and by means of an axially provided threaded hole 26 connectable with an inner drill pipe.
- an external thread 25 with an outer Drill pipe
- an axially provided threaded hole 26 connectable with an inner drill pipe.
- Fig. 2 shows a preferred embodiment of the rotary impact device 1, for separately driving an inner and an outer drill pipe is provided and to a hollow cylindrical percussion piston 4 and one with the Percussion piston 4 cooperating hollow cylindrical Impact hammer 61 has, with axially extending Bores 44; 62 are provided. In these holes 44; 62 the percussion piston 4 and the percussion hammer 61 are Drive means 30, 40 provided for the second drill pipe, that of a second rotating device 50 and a second Impact device 60 driven and one with a Thread 201 provided inner rotary beater 200 are connected.
- the inner drill string can also be used directly with be connected to the drive means 30, 40.
- Inside and external drill pipe, possibly also in the as an adapter Serving rotary beaters 2, 200 are preferably Channels provided, the supply and removal of a flushing medium or the implementation of electrical lines.
- the inner insertion end 30 is from the second rotating device 50 driven while the inner percussion piston 40 regardless of the second impact device 60 is charged.
- the functioning of the inner Einsteckendes 30 and the inner percussion piston 40 and the associated drive devices 50, 60 therefore corresponds to the Operation of the corresponding external device parts 3, 4, 5 and 6.
- the inner insertion end 30 is therefore also largely decoupled from the whipping powers of the second impact device 60 via the inner percussion piston 40th be transferred to the inner drill pipe. early Material fatigue at critical points will therefore also in these inner device parts 30 and 40 and the inner rotary impact receiver 200 and the drill pipe avoided.
- the in the holes 44; 62 of the percussion piston 4 and the Impact hammer 61 provided drive means 30, 40 can Of course also differently designed and operated become. It is possible to use only one inner one Shaft that acts turning, hitting or turning is.
- Fig. 2 is also a further preferred embodiment of the rotary impact receiver 2 facing the second end piece 43 of the percussion piston 4 can be seen.
- the end piece 43 has the shape of a flange, the partially sunk into the insertion end 3 and on one side one provided in the axially extending bore 37 Shoulder 39 can rest, the return of the Impact piston 4 prevented.
- the tail 43 is on the another side in a proposed in Drehtschempftuler 2, the end piece 43 adapted recess 24 sunk. Thereby Other areas of the rotary impact receiver 2 can be relieved so that material damage there is avoided.
