Definitions

  • the invention relates to a device for drilling in rock, ore or the like.
  • a device for drilling in rock, ore or the like For driving or tunnel construction with a mobile, articulated car according to the preamble.
  • anchor technology has been used for securing tunnels in ever greater numbers. Hiebei is proceeded in such a way that after the completion of the blasting and clearing work, boreholes are drilled into the grown rock, which are arranged approximately normal to the tangent in the respective tunnel profile, whereupon steel anchors, which have a thread, a plate and a nut at one end, be fixed in the borehole.
  • This fixation in the borehole can be done either with a hydraulic binder but also with thermosetting binders or the like.
  • the screw nut is tightened so that a compressive stress is applied to the rock via the steel plate located between the rock and the screw nut, which in many cases provides a completely sufficient expansion of the tunnel gallery or the like. So far, it has been done so that the drilling of the blast holes, i.e. those drill holes which are arranged in the direction of advance, and the drilling of the anchor holes, the drilling direction of which is approximately vertical or radial to the direction of advance of the blast holes, were carried out completely independently of one another, due to the different drilling directions various drilling rigs have also been used.
  • a device for drilling in rock can be seen from the literature "Mining Annual Review” 1975, page 179.
  • this device has at least three brackets and drilling arms, the drill arms of which can be raised, swiveled and lowered and which carry a drill carriage with a rotating motor and feed motor articulated.
  • the device is driven by a hydraulic device.
  • EP-A-0 083 334 shows the design of a drilling arm, which allows the drilling arm to be left in one position both when drilling and when loading the borehole, the drill carriage being easy to position and precisely adjusted .
  • a device for propelling blast holes which carries a plurality of drilling arms, the drilling arms arranged on the side being telescopic in the direction of advance.
  • such a device is in no way suitable for solving the task, since such a device is too space-intensive and, furthermore, the necessary drill holes for anchoring cannot be carried out.
  • the present invention has set itself the goal of creating a device for drilling in rock, in particular for mining, which allows to make explosive holes and anchor holes simultaneously without a large space requirement even on a route with about 5 m width and 4 m height , whereby the anchor holes are naturally made in the area that was previously created by the blasting and clearing work. Furthermore, it should be ensured that the operating elements for the drilling devices, be it for the blast holes or for the anchor holes, do not have to operate in the unsecured area. Another object of the present invention is that the drilling device is brought to the site once, no longer has to be moved, but that the corresponding movements of the drilling units can be carried out independently of one another and simultaneously, so that the set-up times and the like are significantly reduced.
  • a drilling arm with bracket which has a shorter and / or telescopic mount than the other drilling arms, is arranged between two others on the carriage and can be moved in the direction of travel with its bracket along a sliding path and arranged parallel to the sole is that in addition two adjacent drilling arms can be moved in the direction of advance, with their brackets can each be moved along a sliding path, the centrally arranged sliding path extending further on site than the two neighboring ones.
  • the drilling carriage can be moved into the working position even under the tightest of spaces, whereby the supports provide exact positioning and alignment of the carriage. Since the drilling arm arranged with a bracket between two other carriages on the carriage can be moved in the direction of advance, from a working position of the drilling carriage, from which all Blast holes are arranged, all or substantially all of the anchor holes radially emanating from the direction of advance are drilled at a distance from one another in relation to the direction of advance, a particularly trouble-free construction being provided when the drilling arm can be moved with its bracket along a displacement path that is parallel can be arranged to the sole.
  • anchor holes can also be driven into the rock in the immediate vicinity of the face, so that the tunnel is optimally secured.
  • a particularly simple and advantageous construction of the drilling arm for anchoring is obtained if the drilling arm, which is arranged to be movable between two others on the carriage in the direction of advance, has a shaft which is arranged normal to the longitudinal direction of the drill boom and parallel to the base.
  • FIG. 1 shows a drill carriage in a side view
  • FIG. 2 shows the drill carriage according to FIG. 1 in a view from above.
  • the carriage 1 has a hydraulic supply 2 and is carried by wheels 3 on the sole. Instead of wheels, caterpillars, portals, rails, etc. can also be provided. Raisable and lowerable supports 4 are provided at the respective ends of the carriage. As can be seen in particular from FIG. 2, the carriage is articulated. At the front end seen in the direction of advance according to arrow a, three displacement tracks 5, 6 and 7 are provided. As can be seen in particular from FIG. 1, these displacement tracks are arranged essentially parallel to the sole. A console 8 with a drilling arm 9 is arranged on the sliding track 6, which extends further on site than the sliding tracks 5 and 7. This bracket 8 can be moved along the displacement path 6 in and against the direction of advance.
  • the rotatable brackets 10 and 11 are longitudinally displaceable along the displacement tracks 5 and 7.
  • the console 8 of the middle sliding track can be displaced further on site than the consoles 10 and 11.
  • Each drilling arm is telescopic and has a feed device (not shown) and a percussion drilling or rotating motor with which the respective Boring bars 12, 13 and 14 are driven into the rock.
  • the drilling arm 9 is arranged above the associated lifting and lowering cylinder 15, at least one of the drilling arms 16 and 17 being arranged below its associated lifting and lowering cylinder 18, 19.
  • the middle drilling arm is also designed to be telescopic, and furthermore the mount 20 is mounted on a shaft 21 which is arranged normal to the longitudinal direction of the drill boom and parallel to the ground.
  • the carriage holder carries a drill carriage 22.
  • a work platform 23 is arranged behind the displacement tracks 5, 6 and 7.
  • the boring bars 12 and 14 which are used to carry out blast holes, can be driven into the chest, regardless of the anchoring work which is carried out, for example, with the boring bar 13.
  • Fig. 1 three boreholes 24, 25 and 26 are shown schematically, which were driven into the ridge, which are spaced from one another, with respect to the direction of advance a.
  • the drilling arm for executing the anchor holes can be moved in and against the direction of advance in a working position of the carriage, so that there is no mutual obstruction, and anchor holes and advance holes can be carried out simultaneously.
  • the number of the individual drilling units is also dependent on the number of drilling or blasting holes required.
  • the carriage 22 for the execution of the anchor holes can be shorter or telescopic, for. B. be designed for anchor guidance of blast holes in the direction of advance, as the carriage for the implementation of the blast holes, since usually the stud height is less than the length of the blast holes.
