CS 273 315 B2

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for boring anchor holes and fixing anchors, for example for mining, tunneling or the like. In mining, especially in coal mining and tunneling, reinforcing corridors with adhesive or spreader anchors is increasingly important. In such a process, it is now generally customary to produce one or more boreholes in a rock, in a radial or perpendicular direction, drawn on the tunnel cross-section, in the rock. Dimensional anchors or concrete or two-component sizing are then introduced into these bores and an adhesive anchor is introduced. After the glue has solidified, which occurs in a short time in the two-component system, the nuts are tightened at the protruding end of the anchor, with a plate positioned between the rock and the nut to prevent surface rock disruption. With such anchors, it is now possible for the rock to be subjected to stresses, in particular compressive stresses, thereby achieving a kind of arch effect, and the rock of the tunnel or the like. forms a kind of self-supporting structure.

Since there is a need to create an anchor hole in the tunnel or adit, not to install the adhesive, to settle the anchor and also to tighten it, there is a great need for these operations to be automated as far as possible to avoid endangering the operating personnel.

A device for boring anchor holes and fixing anchors having a carriage has been already known, along which a drill motor or an anchor fixing key can alternately travel with another motor. At the end of the carriage which faces away from the bore there is a device which extends across the carriage and on both sides over the carriage and serves to accommodate the drilling unit or the anchor key wrench motor, both the drilling motor and the anchor key wrench motor. It is located on its own suction and can be moved from the working position on the carriage along the guide to the rest position, after which the second unit can be brought into working position. This movement of the units must be carried out either manually or by means of additional rollers.

In addition, the device has an anchor magazine with a chain, which magazine can be pivoted as required so that the anchor can be removed from the magazine. The anchor-setting unit and the anchor-setting key can be moved from the working position to the rest position without the anchor, while the translation drill has to be pulled together during translational movement from the working position to the rest position, thus also requiring a transverse slide guide for the drill.

This known apparatus for drilling anchor holes and for anchoring settling is expensive in terms of apparatus, since it requires, for example, a drilling unit and anchoring settling unit, a guide running across the carriage and serving for the resting positions of the units, and of the anchoring container and the supply pipe for the adhesive substance, a large volume, whereby its use, in particular in mining, is only possible to a limited extent. In addition, the device has a particularly high failure rate as a result of the additional transverse guide, so that the operator has to re-enter the unreinforced mine corridor to bring the machine back into operation, or the car must be pulled out of the unreinforced corridor and and for anchoring, the wagon must be re-guided into the unreinforced corridor and put there again.

SUMMARY OF THE INVENTION The object of the present invention is to provide an anchor drilling and anchoring device so as to enable the entire operation to be carried out in such a way that the operator does not have to enter the unreinforced area while maintaining a compact design and particularly high operational safety.

Apparatus for boring anchor holes and settling anchors, for example in mining, tunneling or the like, which is connected via a carriage, a carriage holder and optionally via a drilling arm to a carriage, cutting machine or the like and comprises a drilling motor, in particular an impact drilling motor provided on the carriage along the carriage, the movable guide of the drill rod, the swiveling magazine for the anchors, the bracket for inserting the anchors, the wrench for settling the anchors movable across the carriage along the carriage, and optionally also an adhesive tube in that the bracket for the anchor magazine, the boring bar guide, the bracket for the anchor setting keys and possibly the bracket

M

CS 273 315 B2 2 of the guide tube are rotatably mounted to the common shaft, wherein the boring bar bearings in the boring rod guide, the anchor seating key and preferably the anchor and possibly also the guide tube are equidistant from the common shaft, the position of the drilling motor, in particular the impact motor, is the same distance from the shaft.

With such a construction, it is possible that boreholes and anchors can be seated and tightened with a single motor. For this purpose, only the drill rod must be removed from the drilling unit and the anchor setting key inserted. The different tool holders or tools are each rotatable in front of the aggregate around the common shaft, making it possible to change the tools in a particularly simple manner, whilst at the same time allowing the lowest space consumption for the entire device. ’

According to a further feature of the invention, the support device which carries the anchor seating key, possibly with flexible clamps, is movable in the longitudinal direction of the carriage, in particular via the ejection and retracting cylinder.

Since, as a rule, the drill rod must be longer than the anchor, it is preferable to first insert the anchor placement key into the engine and then insert the anchor into the anchor placement key. Such a procedure is made possible by the mobility of the key holder for setting the anchors in the longitudinal direction of the carriage.

According to a further embodiment of the invention, in the swiveling direction, when viewed in the swiveling direction of the swiveling around the shaft between the drill stem guide and the anchor magazine holder device, an anchor settlement device holder device is provided.

This makes it possible to achieve a particularly fast working process with a particularly simple control, since only the rotation around the shaft in one direction has to be performed for the working procedure.

According to a further embodiment, the insertion tube and the anchor settlement key on the shaft have the same angular position and a retractable anchor gripper is provided for receiving the anchor from the anchor magazine moved by the drill motor.

This embodiment has the advantage that, in one position, an anchor key and an adhesive substance, in particular a two-component adhesive system, can be introduced into the motor. If, furthermore, a retractable anchor gripper is provided for removing the anchor from the anchor magazine displaced in front of the drill motor, the anchor magazine may be removed in this position and the anchor hook may be retracted when the anchor is introduced into the bore. They are already provided in the magazine, thus eliminating the need for any further manipulation, for example by manually inserting the rain and nut or additional automatic operation. ^b

A particularly simple design solution is achieved when the anchor magazine holder device, the anchor holder wrench device and the at least one drill rod guide are immovably provided on a common shaft.

In order to be able to guide the drill stem also between the front drill stem guide rigidly mounted on the rotatable shaft and between the drilling unit in the initial position, at least one further drill stem guide can be provided on the shaft according to another embodiment of the invention.

According to a more preferred embodiment of the invention, a rotating cylinder is provided for rotational movement of the anchor magazine holder device, the anchor holder wrench device and the guide of the drill rod around the common shaft.

Such a rotatable constructive arrangement ensures particularly trouble-free operation, while at the same time space consumption is kept low.

In order to make it particularly easy to insert the adhesive material into the bore, the insertion tube for the adhesive material can be movable in the longitudinal direction of the carriage according to a further embodiment of the invention.

A particularly compact construction is obtained according to another embodiment in the case where the shaft is formed

CS 273 315 B2 t * del is mounted on or on the front plates of the carriage.

Preferably, the faceplate carries an anchor gripper and possibly a support mandrel.

If, in relation to the carriage, a slide-sliding motor for the sledge is provided against the drill motor in one suction position, then a particularly simple construction is given.

If, according to another embodiment of the invention, the carriage carrying the drill motor is partially movable beyond the end of the carriage which faces away from the bore, the carriage may be kept shorter, and the carriage may be extended out over the carriage end to introduce the drill rod.

The invention will now be explained by way of example with reference to the drawings.

Giant. 1 shows a device for boring anchor holes and for anchoring the anchors in oblique projection, and FIGS. 2, 3, 4, 5 and 6 show the different working positions of the device according to FIG. 1 in a side or top view, respectively.

The device for drilling anchor holes and settling anchors shown in FIG. 1 has a carriage 6 which carries front plates 2 and 6 at both ends thereof. A carriage 6 is displaceably mounted along the carriage 6 on which the drill motor 6 is arranged. The carriage 6 is moved by a sliding motor 6 by means of a chain 6 which is tensioned by a tensioner 6. A cover 6 is placed over the feed motor 6. The carriage 6 is connected via a carriage holder (not shown) to a drill carriage, for example via a drill arm or the like. It can also be carried out in such a way that the carriage 6 is located, for example, on a cutting machine.

-and

In the front plates Z and 6 a shaft 10 is mounted parallel to the carriage 8, which can be rotated by means of a rotating roller 80. The shaft 10 also carries the drill rod guide 12, 14, 14, the drill rod guide 17 being fixedly mounted on the shaft 10, while the drill rod guide 14, 14 is rotatable from their working rollers via their own rollers 15, 16. Thus, the drill rod assembly 17 with the drill bit 1B is fully guaranteed. Further, on the shaft 10 there is a bracket device 48 which, by means of spring clips 21, carries an anchor key 20. The anchor holder 19 for the anchor seating keys 20 is moved by the insertion and ejection cylinder 22. Further, a holder 23 for the anchor magazine 24 is provided on the shaft 10. The anchor magazine 24 further has support disks 25, 26 which are rotatably mounted in the holder 23 and The individual anchors 28 already have plates 29 in the anchor magazine 24 which are held in position by the nuts (not shown). A holder 30 of the adhesive tube 31 is fastened to the shaft 10. This holder 30 i with the insertion tube 31 can be moved by the auxiliary roller 32 in the longitudinal direction of the carriage. The anchor gripper 33 is also mounted in the end plate. The faceplate further carries a support mandrel 34, which is optionally a retractable.

The operating procedure of the device according to the invention is as follows:

In the position (1) shown in FIG. 2, the support mandrel 34 is supported on the arch 35 of the mine work. The carriage 6 is in this case in the vertical direction. By means of the roller 11, the drill rod 17 located in the guides 44, 14, 14 is introduced in front of the rotary drill motor 8, which at this point is extended out beyond the end of the carriage 6, whereupon the motor moves back to the ceiling or vault. the rod 17 engages the motor drill insert, i.e. the drill chuck. The bearings in the guides 14, 14 of the drill rod 17 are equidistant from the shaft 10, thereby ensuring parallel alignment of the drill rod 17.

Upon completion of the bore, it is now proceeded by first extending the guide 14 which carries the drill rod 17 over the clamps, thereby keeping the drill rod 17 in a rest position. The drilling of the borehole is then continued until the carriage 8 reaches the guide 13, which is also pivoted, whereupon the borehole can be completed and the motor and the drill rod are again moved along the carriage 6.

Then, the guide rails 14, 14 are again engaged with the drill rod 17, the carriage 4 and the motor are moved out of the carriage 8 so that the drill rod is removed from the drill chuck, whereupon the drill rod is pivoted from the working position by rotating the shaft 10. At the same time, the anchor seating device 19 with the anchor seating key 20 and the holder 30 with the adhesive insertion tube 31 are brought into working position. This position is marked with

CS 273 315 B2 (2) in Fig. 3. The actual task position is clearly evident from the positions indicated by the indexes

From position (1a) in Fig. 2, it is particularly clear that the bearing for the drill rod 17.

the anchor wrench 20 for the anchor and the anchor 28 are equidistant from the shaft 10.

In the position (3) of FIG. 4, the anchor settlement key 20 is inserted into the impact drill motor 5. Further, the insertion tube 31 is advanced to the bore hole 36.

In the working position (4) of FIG. 5, the anchor magazine 24 is pivoted in front of the impact drill motor 8 so that the anchor gripper 33 can engage the anchor 28 of the anchor magazine 24, whereupon the impact drill motor 6 moves in the longitudinal direction of the carriage. 28 - as shown in the working position (5) of FIG. 6 - engages the anchor key 20. The armature 28 is then rotated by the impact drill motor 6 in a direction opposite to the screw tightening direction into the bore, mixing the two-component glue that has been introduced into the bore, then waiting for the two-component glue to solidify and turn the nut in the opposite direction. thus allowing it to be tightened. Since the anchor gripper 33, as shown in the working position (5a) in FIG. 6, pivots, and the pivoting movement is effected via the cylinder 27 itself, the anchors 28 can already be provided with an anchor plate and nut in the magazine.

The slide 4 with the impact drill motor 4e is then moved back to their end position, whereupon the anchor key 20 of the anchor with the holding device 19 brought into working position is removed from the unit. Thereafter, the entire working process starts again, with the working tools not rotating around the shaft 10 as a shaft, but followed by a maximum oscillation of 220 ° (see FIG. 5) of the position (4a).
