Definitions
- the invention relates to an insertion end according to the preamble of claim 1.
- Such insertion ends are generally known. They serve as a link between a drill drive, e.g. B. a hydraulic hammer drill on the one hand and the facing end of an anchor rod, especially one Anchor rod on the other hand and in this capacity transfer all For example, forces and moments resulting from drilling operations.
- a drill drive e.g. B. a hydraulic hammer drill on the one hand
- an anchor rod especially one Anchor rod on the other hand and in this capacity transfer all For example, forces and moments resulting from drilling operations.
- Injection drill anchors are known as boring bars and as rock anchors used. They perform the function of a while drilling a well Boring bar through the central longitudinal bore of a flushing medium, for. B. water, Air or a curable medium, e.g. B. a cement suspension stream.
- the flushing agent is used to cool the drill head and to wash it out the loosened on the borehole bottom as a result of the drilling progress Mountain particles.
- the central longitudinal bore now a curable medium in the borehole introduced, which the annular space surrounding the anchor rod, in the area starting from the bottom of the borehole and towards the mouth of the borehole progressively fills and after hardening a bond between the Anchor rod and the borehole walls.
- the drill anchor remains in this case as a "lost tool" in the borehole and is by means of an anchor head plate and a clamping nut supported on this on the air side braced against the surrounding borehole walls.
- the sticking end is equipped with a cable for this purpose a fluid medium into the drill rod using the adapter part can be introduced.
- a fluid medium into the drill rod using the adapter part can be introduced.
- the insertion end is independent of the for routing the flowable medium determined line with a another cable line is equipped to carry a cooling medium.
- the cooling medium is placed at a suitable point in the structure of the insertion end introduced and leaves this at another place.
- that Cooling medium in a known manner via the drill drive, in particular via Drill-own means are introduced into the cable line mentioned.
- a ring-like stop body By a ring-like stop body according to the features of Claim 3 is a secure transmission of the resulting from the drilling operation Given reaction forces to the insertion end.
- the stop body can on the coupling section intended for connecting the anchor rod be screwed on.
- This screw section is relative to that Adapter part-carrying section designed such that after removing the called stopper the adapter part pulled from the insertion end can be. It is essential in any case that the adapter part opposite all forces and moments resulting from the drilling operation as far as possible is decoupled and thus arranged with little stress.
- the axis of the insertion end according to the invention is designated, the one, here left-hand end as the drive-side coupling section 2 and its other right-hand end as the output-side coupling section 3 are determined and designed.
- this coupling section 2 and that Front side 5, the impact energy into the insertion end in percussion drilling operation initiated.
- the insertion end is thus used for transmission all for the drill feed to be generated by the drill drive required forces and moments on the boring bar. This Forces and moments are determined according to the required drilling speed, the impact frequency, the drilling feed, etc. via the coupling section 2 introduced into the insertion end.
- the coupling section 3 is not for coupling a drawing shown boring bar, for example an injection drill anchor with an external thread, here preferably a round thread, boring bar thread or the like equipped.
- the length of the cable run defined by holes 6 to 8 is designed depending on the necessary cooling capacity.
- a drill drive e.g. a hydraulic hammer drill in connection
- the Input bore 7 is located within the structure of this drill drive and is appropriately charged with a cooling medium.
- the Coolant flows through the bore 6, absorbs heat and leaves this via the output bore 8, which is outside in any case the structure of the drill drive.
- surrounding the mouth of the outlet bore 8 Housing the cooling medium can be collected and if necessary further recycling, possibly reuse after cooling, be fed.
- the section 9 of the insertion end is for putting on the one shown in FIG. 2 Adapter part 10 determined. It is this section with one radial, cross-sectionally oval bore 11 provided in continuous connection with one, in the direction of axis 1 extends bore 12, which is otherwise in the front 13th flows into.
- the bore 12 extends axially only in the rest to the area of the bore 11.
- the through the holes 11, 12 defined cable run serves for the optional guidance of a flushing medium, such as. Water or air, a curable medium, e.g. a cement suspension, a synthetic resin mixture or almost one any mix of these media.
- the flushing medium is used in known way during the drilling feed both the cooling of the Boring bar as well as flushing out as a result of the drilling progress Mountain particles loosened in the area of a drill bit.
- the in the case of, for example, curable medium is used Injection drill anchor introducing this medium into the borehole over the central longitudinal bore of the anchor or drill rod and after Curing their fixing within the borehole.
- the chosen anchor setting method can also be a curable one Medium, e.g. a cement suspension, simultaneously as a rinsing medium and used as a curable medium, so that in a uniform Working process creates the borehole and this at the same time with a hardenable medium - while rotating the drill anchor - is at least partially backfilled.
- Ring body referred to that a stop function for the drilling or anchor rod section to be screwed onto this coupling section 3 or the like met and beyond the recording reaction forces resulting from the drilling operations.
- the adapter part 10 consists of a fixed housing part 15, which is rotationally symmetrical with respect to axis 1 of the insertion end is formed and its section 9 leaving an annular space 16 surrounds.
- the annular space 16 stands over a radially oriented one through bore 17 with a pipe connection 18 in connection, the can be welded to the housing part 15, for example, and its free end with a threaded section 19 or another Coupling section is provided.
- the pipe connection 18 is otherwise on a laterally attached gusset 20 supported on the housing part 15.
- the front ends of the housing part 15 are each by running disks 21, 22 formed, which are screwed to the housing part 15 and made of a low-friction plastic, such as Polyamide, can exist.
- the sealing rings 23 and the disks 21, 22 are symmetrical on both sides a radial center plane 24 of the adapter part 10, which is otherwise placed on section 9 such that the bore 11 is located approximately in the region of the central plane 24.
- the running disks 21 serve to provide a damping effect compared to those from the percussion drilling operation in the axial direction as required the impact frequency occurring stress.
- the insertion end according to the invention thus forms the link between a drill drive on the one hand and a drill rod to be driven, injection drill anchor or the like on the other hand. It forms at the same time the component via which, for example, in the case of an injection drill anchor a flowable medium is introduced into it, whereby it depends on the drilling method or the anchor setting method any flushing medium or a hardenable medium can act.
- the insertion end is spatially separated from one another separate cable runs on the one hand for a cooling medium and on the other hand for when drilling a borehole or setting a rock bolt required flowable medium equipped. In particular are any interactions due to this spatial separation between the drill drive on the one hand and the latter flowable medium, which is, for example, a mortar suspension can act prevented.
