Definitions

  • the invention relates to an anchor drilling and setting device e.g. for mining, tunneling or the like
  • An anchor drilling and setting device has already become known, which has a mount, along which alternately the drilling unit or the anchor setting key can be moved with another motor.
  • a mount At the end of the carriage facing away from the borehole there is a receptacle for the drilling unit or the motor for the anchor setting key which extends transversely to the borehole and extends beyond it on both sides.
  • Both the drill motor and the motor of the anchor setting key are located on their own slide and can be moved from a working position on the carriage along the guide to a rest position, after which the other unit can be moved into the working position. This movement of the units must either be done manually or with additional cylinders.
  • this device has an anchor magazine with chain, which can be swung forward so that an anchor can be removed from the magazine if necessary.
  • the unit for the anchor setting and the anchor setting key can be moved from the working position to the rest position without an anchor, whereas the drill has to be taken into the rest position during the translational movement from the work, which also requires a displaceable
  • This known anchor drilling and setting device is expensive in terms of equipment, since it requires, for example, a drilling unit and a unit for setting the anchor, has a guide arranged transversely to the carriage for the rest positions of the units and is claimed due to the arrangement of the transverse guide, the anchor magazine and the insertion tube for the adhesive has a large volume, which means that its use, particularly in mining, is only possible to a limited extent. Furthermore, there is a particularly high susceptibility to malfunctions due to the additional lateral guidance, so that the operator has to go again into the undeveloped area of the line to get the device working again to bring or the entire wagon must be withdrawn from the undeveloped line and after repairing the anchor drilling and setting device the wagons must be brought back into the undeveloped line and realigned there.
  • the object of the present invention is now to provide an anchor drilling and setting device which allows the entire work process to be carried out in such a way that the operator does not have to be in the undeveloped area, while at the same time a compact design should be possible and it should also The operational safety can be kept particularly high due to a simple construction.
  • the anchor drilling and setting device for example for mining, tunneling or the like, which can be connected to a carriage, a cutting machine or the like via a mount, mount holder, possibly a drilling arm, with a drilling, in particular rotary impact motor, which is slidably arranged on a carriage along the carriage, a movable boring bar guide, a pivotable anchor magazine, an anchor holder for setting the anchors, an anchor wrench that can be moved along the carriage via a carriage, possibly an insertion tube for the adhesive, e.g.
  • the holder for the anchor magazine, the drill rod guide, the anchor setting key holder and optionally the holder for the insertion tube are rotatably arranged about a common axis, the receptacle for the drill rod in the drill rod guide, the anchor setting key and preferably an anchor and possibly the insertion tube the same n
  • the receptacle for the drill rod in the drill rod guide, the anchor setting key and preferably an anchor and possibly the insertion tube the same n Have a distance from the common axis, whereby in every position of the drill bit special rotary impact motor the distance of the same from the axis is constant.
  • the various brackets or tools are each rotatable about a common axis in front of the unit makes it particularly easy to change the tools, while at the same time requiring the smallest space for the entire device.
  • the anchor setting key holder which carries the anchor setting key, possibly with resilient receptacles, can be moved in the longitudinal direction of the mount, in particular via an engagement and disengagement cylinder. Since, as a rule, the boring bar must be longer than the anchor, it is advantageous to first insert the anchor setting key into the motor and only then to insert the rock anchor into the anchor setting key. Such a procedure is made possible by the mobility of the anchor setting key holder in the longitudinal direction of the carriage.
  • the anchor setting key holder is arranged between the boring bar guide and the anchor magazine holder, viewed in the pivoting direction around the axis, a particularly rapid working process can be made possible with particularly simple control, since the rotation about the axis only has to take place in one direction for the working process.
  • the anchor setting key can be inserted into the motor in one position and the adhesive, in particular the two-component adhesive system, can be introduced into the borehole at the same time.
  • an armature gripper that can be engaged and disengaged is provided for receiving an armature from the armature magazine moved in front of the drill motor, an armature can be removed from the armature magazine in this position, wherein the armature gripper can be disengaged again during the insertion of the armature into the borehole, so that the armature mit.the disc and the nut can already be arranged in the magazine, whereby any further manipulation, e.g. manual application of the plate and nut or an additional automatic workflow is not required.
  • a structurally particularly simple solution is obtained if the holder for the armature magazine, the armature setting key holder and at least one boring bar guide are arranged in a rotationally fixed manner on the common axis.
  • At least one further boring bar guide can be pivotably arranged on the axle.
  • the rotation of the holder for the armature magazine, the armature setting key holder and the boring bar guide about the common axis is carried out by a motor, in particular a rotating cylinder.
  • a motor in particular a rotating cylinder.
  • the insertion tube for the adhesive can be movable in the longitudinal direction of the carriage.
  • a particularly compact design results when the axis of rotation is mounted on or in the end plates of the mount.
  • the anchor gripper can be brought particularly close to the borehole if the borehole is arranged on an end plate, which optionally carries a support mandrel.
  • a feed motor for the carriage is arranged in relation to the carriage in a setting of the carriage with respect to the carriage, the construction is particularly simple.
  • the carriage which carries the drill motor can be partially moved over the end of the carriage facing away from the borehole, the carriage can be kept shorter, and the carriage can be moved beyond the carriage end to insert the drill rod into the motor.
  • FIG. 1 shows an anchor drilling and setting device in an oblique view
  • FIGS. 2 and 3 show the different working positions of the device according to FIG. 1 in a side and top view.
  • the anchor drilling and setting device shown in FIG. 1 has a mount 1 which carries end plates 2 and 3 at its two ends.
  • a Carriage 4 movable, on which a rotary impact motor 5 is arranged.
  • the carriage 4 is moved by the feed motor 8 via a chain 6, which is tensioned by a chain tensioner 7.
  • a cover 9 is provided over the feed motor.
  • the carriage is connected to a drilling carriage, for example via a drilling arm or the like, via a carriage holder (not shown). Provision can also be made to arrange the carriage, for example on a cutting machine.
  • an axis 10 is mounted parallel to the carriage, which can be rotated via a rotary cylinder 11.
  • the axis 10 also carries boring bar guides 12, 13, 14, the boring bar guide 12 being rigidly attached to the axis, whereas the boring bar guides 13, 14 can be rotated out of their working position via their own cylinders 15, 16, so that the drilling unit 5 moves along the The carriage is not hindered and on the other hand the guidance of the boring bar 17 with the drill bit 18 is fully guaranteed.
  • Puf the axis 10 is the anchor setting key holder 19, which carries the anchor setting key 20 via spring clips 21, attached. The anchor setting key holder is moved over the engagement and disengagement cylinder 22.
  • a bracket 23 for the armature magazine 24 is also provided on the axis.
  • the armature magazine has receiving disks 25, 26 which are rotatably mounted in the holder and can be rotated by a rotating cylinder 27.
  • the individual anchors 28 already have plates 29 in the magazine, which are held in position by nuts (not shown).
  • a holder 30 for the insertion tube 31 for the adhesive is fastened on the axis. This holder together with the insertion tube 31 can be moved in the longitudinal direction of the carriage via a cylinder 32.
  • An anchor gripper 33 is also mounted in the end plate.
  • the end plate also carries a support mandrel 34, which can be extended if necessary.
  • the support mandrel 34 is supported against the ridge 35.
  • the carriage 1 is in this case in the vertical direction.
  • the boring bar which is located in the boring bar guide 12, 13, 14, is brought in front of the rotary impact motor 5, which at this time has moved beyond the carriage end, after which the motor is moved again to the ridge, so that the boring bar in the motor chuck comes into engagement.
  • the receptacles in the boring bar guides 13, 14 are at an identical distance r from the axis 10, which ensures the parallel alignment of the boring bar.
  • the procedure is now such that first the boring bar guide 14, which carries the boring bar via a spring clip, with which the boring bar is held in the rest position, disengages. After that, the drilling is continued until the carriage reaches the boring bar guide 13, which is also swung out, after which the borehole can be completed, and the motor together with the drill pipe is moved again along the mount.
  • the armature magazine 24 is rotated in front of the rotary impact motor in such a way that the armature gripper 33 can engage an armature 28 of the anchor magazine, whereupon the rotary impact motor is moved in the longitudinal direction of the carriage and the anchor - as shown in position 5 - engages in the anchor setting key.
  • the magazine is then pivoted out, an anchor being removed from the anchor magazine at the same time.
  • the anchor is then rotated into the borehole by the rotary impact device in the opposite direction to the tightening direction of the screws, whereby the two-component adhesive which has been introduced into the borehole is mixed, and then it is briefly waited until the two-component adhesive has solidified and the nut is rotated in the opposite direction, whereby it is possible to tighten them. Since the armature gripper 33 is pivoted out, as shown in FIG. 5a, the pivoting movement being carried out via its own cylinder 27, the armature can already be provided with the armature plate and nut in the magazine.
  • the slide with a rotary impact motor is then moved back into its end position, whereupon the anchor setting key with the anchor setting key holder 19 which has been brought into the working position is removed from the unit.
  • the entire work sequence then begins again, the work tools not being rotated in their entirety about the axis 10, but rather a swiveling movement by a maximum of 2 20 0.
