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. a hydraulic hammer drill, on the one hand, and the facing end of an anchor rod, in particular a drill anchor rod, on the other hand, and in this capacity transmit all the forces and moments resulting, inter alia, from the drilling operation.
- a drill drive e.g. a hydraulic hammer drill
- an anchor rod in particular a drill anchor rod
- Injection drill anchors are known to be used as drill rods and as rock anchors.
- a winding medium for example water, air or a hardenable medium, such as a cement suspension.
- the rinsing agent serves to cool the drill head and to flush out the mountain particles that have been loosened on the borehole bottom as a result of the drilling progress.
- a hardenable medium is now introduced into the borehole via the central longitudinal borehole, which fills the annular space surrounding the anchor rod, beginning in the area of the borehole bottom and progressing towards the borehole mouth, and after hardening Connects between the anchor rod and the borehole walls.
- the drill anchor remains in the borehole as a “lost tool” and is braced on the air side against the surrounding borehole walls by means of an anchor head plate and a clamping nut supported on it.
- a hardenable medium during the drilling phase which is particularly suitable for low-cohesive mountains, but also the introduction of a hardenable medium with simultaneous rotation of the drill anchor, requires the use of a component arranged between the insertion end on the one hand and the facing drill rod rod on the other hand, which is an adapter part or carries a rotary injector and via which the flowable, in particular curable medium is introduced into the drill rod.
- this constellation Due to different steel qualities in the area of this component on the one hand and the insertion end as well as the drilling drive on the other hand, this constellation causes problems with regard to loosening the screw engagement between the named component and the facing drilling anchor rod end after the anchor setting process has been completed. This is because the forces and moments transmitted during drilling operations always lead to plastic deformations and thus extremely tight screw connections, which as a result can only be loosened with great difficulty. In addition, the component mentioned, which carries the adapter part, is also exposed to considerable mechanical stresses.
- the insertion end is designed directly as a carrier for the adapter part and also in the context of the task set out at the outset, directly for coupling the facing part End of an anchor rod is used.
- the loosening of the drilling drive is thus restricted to the loosening of the connection, as a rule the screwing of the insertion end to the facing end of the drill anchor rod.
- the insertion end is equipped with a cable, via which a fluid medium can be transferred into the drill rod by means of the adapter part.
- the fact that the adapter part, in particular the portion of the insertion end that carries this, is located outside the structure of the drill drive creates an essential prerequisite for excluding any interactions between the actual drill drive and the curable, flowable medium, for example in the case of defective seals. Thus, there is no fear of impairing the function of the drill drive due to the extended use of the insertion end in the above sense.
- the insertion end is equipped with a further line for guiding a cooling medium, regardless of the line set intended for guiding the flowable medium.
- the cooling medium is introduced into the structure of the insertion end at a suitable point and leaves it at another point.
- the cooling medium can be introduced into the mentioned cable run in a manner known per se via the drill drive, in particular via the drill drive's own means.
- a ring-like stop body in accordance with the features of claim 5 ensures reliable transmission of the reaction forces resulting from the drilling operation to the insertion end.
- the stop body can be screwed onto the coupling section intended for connecting the anchor rod.
- This screwing section is designed relative to the section carrying the adapter part in such a way that, after removing the abovementioned stop body, the adapter part can be pulled from the insertion end. It is essential in any case that the adapter part is largely decoupled from all forces and moments resulting from the drilling operation and is therefore arranged with little stress.
- Figure 1 is a view of an insertion end according to the invention in partial longitudinal section.
- Figure 2 is a view of an adapter part intended to cooperate with the insertion end in partial longitudinal section;
- FIG. 3 shows an end view of the insertion end corresponding to a plane III-III of FIG. 1.
- 1 designates the axis of the insertion end according to the invention, one end of which, here the left-hand end, is determined and designed as the drive-side coupling section 2 and the other right-hand end of the drive-side coupling section 3.
- the coupling section 2 is designed for coupling a conventional hydraulic hammer drill with a circumferential one, for insertion into a speaking counter profile certain toothing 4 equipped, via which the required rotary movement about the axis 1 is initiated in the insertion end in the case of a rotary drilling operation.
- the impact energy is introduced into the insertion end via this coupling section 2, specifically via its end face 5, during percussion drilling operation.
- the insertion end thus serves to transmit all the forces and moments required for the drilling feed to be generated by the drilling drive to the boring bar. These forces and moments are introduced into the insertion end via the coupling section 2 in accordance with the required drilling speed, the impact frequency, the drilling feed, etc.
- the coupling section 3 is equipped for coupling a boring bar, not shown in the drawing, for example an injection drill anchor with an external thread, here preferably a round thread, boring bar thread or the like.
- the procedure can be such that the hole 6 is created starting in the end face 5 of the insertion end up to the starting point of the exit hole 8, whereupon the holes 7, 8 are made and then the bore 6 in the area of the coupling section 2, in particular the end face 1, is closed.
- the length of the cable run defined by bores 6 to 8 is designed depending on the necessary cooling capacity.
- this is connected to a drilling drive, for example a hydraulic hammer drill, the input bore 7 being located within the structure of this drilling drive and being supplied with a cooling medium in a suitable manner.
- the cooling medium flows through the bore 6, absorbs heat and leaves it via the output bore 8, which is in any case outside the structure of the drill drive.
- a housing not shown in the drawing
- the cooling medium can, if appropriate, be collected and fed to a further utilization, possibly reuse after cooling.
- the section 9 of the insertion end is intended for the attachment of the adapter part 10 shown in FIG.
- This section is provided with a radial bore 11 which is oval in cross section and is in continuous connection with a bore 12 which extends in the direction of the axis 1 and which, moreover, opens into the end face 13.
- the bore 12 extends axially only into the area of the bore 11.
- the line defined by the bores 11, 12 is used for the optional guidance of a flushing medium, such as water or air, a hardenable medium, such as a cement suspension, a synthetic resin mixture or an almost any mixture of these media.
- the flushing medium serves both for cooling the boring bar and for flushing out rock particles loosened as a result of the drilling progress in the area of a drill bit during the drilling feed.
- the hardenable medium is used to introduce this medium into the borehole via the central longitudinal bore of the anchor or drill rod and, after hardening, to fix it within the borehole.
- a hardenable medium such as a cement suspension
- the adapter part 10 consists of a stationary housing part 15, which is rotationally symmetrical with respect to the axis 1 of the insertion end and the section 9 of which surrounds an annular space 16.
- the annular space 16 is connected via a radially oriented through bore 17 to a pipe connection 18, which can be welded to the housing part 15, for example, and the free end of which is provided with a threaded section 19 or another coupling section.
- the pipe connection 18 is supported on the housing part 15 by way of a laterally attached gusset plate 20.
- the front ends of the housing part 15 are each formed by running disks 21, 22 which are screwed to the housing part 15 and which are made of a low-friction plastic, such as e.g. Polyamide.
- the sealing rings 23 and the running disks 21, 22 are arranged symmetrically on both sides of a radial central plane 24 of the adapter part 10, which is otherwise placed on the 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 against the stress occurring from the percussion drilling operation in the axial direction in accordance with the percussion frequency.
- the insertion end 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.
- a flowable medium is introduced into it, which can be any flushing medium or a hardenable medium, depending on the drilling method or the anchor setting method.
- the insertion end is equipped with spatially separated cables for a cooling medium on the one hand and for the flowable medium required when drilling a borehole or when installing a rock anchor on the other. In particular, due to this spatial separation, any interactions between the drill drive on the one hand and the latter flowable medium, which can be a mortar suspension, for example, are prevented.
