Definitions

  • the invention is concerned with drilling large rock surfaces, e.g. B. in marble and granite quarries, and relates to a device for drilling holes and / or slots in vertical and in the horizontal direction.
  • the drilling tools are operated individually, in pairs or in a multiple arrangement and are guided on corresponding drilling carriages.
  • These mountings are in the known drilling devices on mobile chassis, z. B. chassis, crawler chassis, or mounted on standard excavators.
  • each drilling position must be approached separately with the drilling device.
  • the carriages are attached to cantilevers, which allow the carriage to move in three planes. Since the boom movements in the known drilling devices take place on circular orbits, the setting up of the drilling tool requires corresponding experience and skill from the operator or an increased expenditure on control and regulation technology.
  • the setup process for each individual hole is associated with a considerable expenditure of time, which has a significant influence on the total drilling time per hole.
  • a reduction in the set-up time for holes lying on a line can be achieved in known drilling devices by using a drilling platform with several drilling devices or a sledge track or a cross plate with displaceable slides.
  • Drilling platforms are already known from tunnel and tunnel construction (see, for example, DE-AS 20 17 738 and DE-PS 12 24 235). These devices are used to drill in front of the drilling platform on the face of the tunnel or the line, preferably in the horizontal direction. They can be moved hanging or standing on rails and equipped with several drilling devices. With suitable adjusting means for height and transverse adjustment of the drilling platform, with a directional beam, e.g. B. a laser, and with actuators for the drilling devices, the drilling tools are positioned. Each carriage with the associated drilling tool is moved and set up individually.
  • a directional beam e.g. B. a laser
  • the UK-PS 13 62 119 presents a drilling platform for driving a route or a tunnel, which is suspended. At least two beams are attached to the ceiling of the tunnel or tunnel parallel to its longitudinal axis, on which a crossbar is suspended so that it can move. A trolley, which can carry at least two drilling devices, traverses the traverse or tunnel axis. Every boring machine Stuff is set up individually for drilling the holes on the working face.
  • the drilling devices have to be set up for each individual hole to be drilled, this requires, among other things. a corresponding control, which can take place automatically with reference to a direct beam. Such a control is described in DE-OS 25 57 048.
  • the size of the known drilling platforms is matched to the dimensions of the tunnel or route profile and is preferably suitable for small areas to be drilled.
  • the devices are designed for horizontal drilling, i.e. H. designed for drilling vertical surfaces. When extracting blocks, bores in the horizontal direction and, to a much larger extent, in the vertical direction are required.
  • a drilling device presented by TAMROCK (Finland) is equipped with a cross shield. At least one carriage on which at least one carriage is arranged travels on the transverse shield.
  • the cross shield is on the boom of a carrier device, for. B. an excavator. It is set up with suitable positioning devices depending on the required drilling direction and held in this position.
  • the drilling tools travel along the cross shield and drill a series of holes parallel to it. The holes match in inclination and depth and lie on a line, so that exact block edges and surfaces are created.
  • the total drilling time per borehole can be reduced with a cross shield, because setting up in two planes is only necessary once for several holes.
  • the length of the row of boreholes depends on the length of the transverse shield. It is generally determined by the load-bearing capacity of the carrier device and the boom, by the pressure forces required for the individual drilling tools and by the stability of the cross shield, and is limited to one or two block lengths.
  • the US 32 25 842 presents a traverse, which is arranged transversely to the direction of travel on a crawler track.
  • a slide is slidably mounted on the crossbar, which and lowerable and swiveling mount with the drilling tool.
  • the length of the crossbeam is only slightly longer than the width of the crawler track, which limits the area of use of the bogie.
  • DE PS 29 13 438 describes a sled track attached to the support frame of a boring truck transversely or longitudinally to its direction of travel, which can be axially extended at least at one end by a side piece.
  • the carriage can be moved, lifted, lowered and rotated on the carriage using the drilling tool.
  • holes can be drilled in a row and in one direction over a distance limited by the length of the track.
  • the axial lengthening of the slide track extends its area of application beyond the external dimensions of the boring car, but it is still limited to approximately two block lengths.
  • a drilling carriage which is particularly suitable for the sole perforation, ie. H. for drilling in the vertical direction.
  • a bearing block with a height-adjustable and pivotable drilling arm is arranged transversely to its longitudinal axis on a central frame provided with a crawler track mechanism. With this drilling arm, the fasteners attached to it and the drilling tool are set up in the required drilling direction and held in this position.
  • the bearing block is slidably mounted on the drilling carriage in its direction of travel (longitudinal axis). By moving the bearing block on the central frame, it is possible to drill a series of holes that lie exactly on a line and run in one direction.
  • the length of the row depends on the dimensions of the central frame and on the performance of the boring truck and is generally limited to two block lengths.
  • the object of the invention is to provide a device of the type mentioned at the outset, with which, over long distances or on large areas which correspond to a multiple of the dimensions of a block to be drilled out, once the device has been aligned with short set-up times for the drilling tools and Large quantities of high-quality blocks can be drilled out with a small amount of work and materials per block obtained.
  • the device according to the invention which is constructed in the form of a drilling bridge, preferably as a rail-bound, self-propelled portal, semi-portal or bridge crane, a large area can be covered.
  • the span of the bridge and the height of the supports are based on the prevailing conditions, e.g. B. adapted the terrain in the quarry.
  • the position and direction of an axis of movement in space is determined by the rails, which are aligned in height and direction.
  • Two or more trolleys on which the drilling devices are mounted move on the drilling bridge.
  • the trolleys which can be moved on the crane girders determine the position and the direction of the second axis of movement in space.
  • the linear travel paths - crane on the crane rails on the one hand and trolley on the crane girders on the other - enable straight rows of boreholes to be covered over longer distances - a multiple of the block dimensions - to be drilled, the drilling direction - transverse and longitudinal inclination - and the row of boreholes being able to be observed exactly.
  • Each trolley is provided with a separate drive and transports two or more height-adjustable and swiveling carriages.
  • the height adjustability enables the drilling equipment to be adapted to the existing terrain.
  • the swivel axis is parallel to the longitudinal axis of the crane girder.
  • the mountings can thus be set up and held as desired with the drilling tools between a vertical and a horizontal position.
  • the required inclination angle in the vertical or in the horizontal direction is, for. B. given by the texture in the rock and is precisely maintained after one-time setup of all drilling tools working on the drilling platform. Then, using a suitable programmable control, drilling a predetermined area can take place essentially automatically if the required hole spacings are entered.
  • the holes are preferably drilled between the two rails on which the drilling bridge travels. If the supports are designed accordingly and if bridge girders with cantilever arms are used which protrude beyond the supports and beyond the rails, bores can also be drilled outside the rail area.
  • a trolley with a lifting mechanism can be provided on the drilling bridge. It is so large that it can be used to lift and load the blocks that have been drilled out.
  • the drilling bridge can be equipped with suitable caterpillars or wheel bogies. This requires a special preparation of the guideways (straightness and flatness) for the bridge in order to ensure the load-bearing capacity and the horizontal alignment of the bridge.

  • the drilling bridge which can be moved on rails 1 and consists of two bridge girders 2 is equipped with two complete supports 3, 4, each of which is provided with a carriage 5, 6. At least one support 4 is in height, for. B. adjustable by removing or adding support segments 7. This allows the bridge to be adapted to the existing terrain.
  • the lifting height of the height adjustment unit 8, which is mounted on each trolley 9 and to which the base plate 10 is fastened with at least two mountings 11, and the drilling depth of the mount 11 with the drilling tools 12 are thus optimally utilized.
  • FIG. 2 the drilling bridge is equipped on one side with a support 3 and the associated undercarriage 5, while on the other side the second undercarriage 6 is mounted directly under the bridge girders 2. If the rail 1 for this undercarriage 6 is laid on a slope of an elevation, the necessary boreholes can be drilled relatively easily on this slope. These terrain sections would be difficult for a mobile device with a wheel or crawler chassis or not available at all.
  • both supports 3, 4 shown in FIG. 1 are removed and the drilling bridge is used as a bridge crane.
  • This form can only be used if the terrain is flat or if the surveys have already been removed.
