Definitions

  • the invention relates to a device for producing a slot by means of a drilling and / or milling tool, which is driven by a motor and moved along the intended path of the slot.
  • the invention relates to a device for producing a slot in rock, the slot in the manufacture of daytime in particular freezer or blind shafts and in the case of mining excavation of underground routes on the periphery of the same mostly to be made arcuate and the slot serves as a pressure transmission lock to prevent the spread of explosive vibrations in the surrounding mountains.
  • slot drilling Another method for slot drilling is known from patent DE-C 3 040 057.
  • the slots are produced by drilling a plurality of drill holes arranged next to one another, depending on the expansion of the slot.
  • the ribs between the drill holes are very annoying when inserting finishing material. It is a process that is not suitable for the problems described and is also very uneconomical.
  • a device for producing a slot by means of a drilling and / or milling tool is also known, which can be driven by a motor and moved along the intended path of the slot.
  • the device can only be operated so that the drill head is always aligned horizontally.
  • FR-A 1 224 143 describes a simple cutter bar without lowering or propulsion device, which is operated at an angle to the mountain surface.
  • the object on which the invention is based is to expand the device according to DE-C 3 040 057 in such a way that with it also arch slots e.g. can be carried out in rock as a milling aid or that it can be used in natural stone extraction.
  • the slot produced by the device according to the invention in a manner that is gentle on the mountains by milling brings in particular the advantage of a smooth mountain surface on which the mountain protection (expansion) in the form of masonry, steel arches with a delay or the like. can be brought close to the mountains. By avoiding unintentional additional outbreaks, expensive backfill material (shotcrete or similar) can be dispensed with.
  • the slot device In the extraction of natural stone in the form of angular, in particular rounded blocks, the slot device is very suitable for the production of arcuate slots, since the rotating and over the entire length with cutting or. Hollow rods equipped with milling tools can also be guided on very small radii.
  • the inventive device for producing slots, for. B. Arch slits in the rock therefore consists of one equipped with cutting or milling tools and a transport spiral Hollow linkage, which is pushed into the rock by a drive unit in a rotational movement and by a lowering or feed device. The linkage is moved either parallel to it or around it on any path by means of a guide device and thus mills out the desired slot.
  • the production of arch slits is therefore possible without any problems.
  • the loosened drill or cut material is removed mechanically or by means of a flushing medium through a flushing device. Vertical to horizontal slots can be made.
  • the device shown in FIG. 1 consists of a carrier body 1 in the form of a hollow rod with an external transport spiral 2, which is equipped with cutting or milling tools 3 completely or at least in the front region (as shown) and on the conical end face 19 on the spiral foot and the spiral outer side is.
  • the carrier body 1 can be made of two (or more) parts 13, 14, which are screwed together at the seam 11 so as to be resistant to bending.
  • the drilling and milling spindle 1 - 2 via the drive shaft 15 or the linkage 20 z. B. at the shaft or route periphery 17 (see FIG. 2) in the mountains 16.
  • the cuttings are discharged via the helix 2 and sucked off at the mouth of the borehole with the feed direction pointing vertically downwards.
  • the hollow rod 1 for the slot production is moved on the circumference of the shaft 17 with the guide device 6, 6, the cutting or milling rod 1 - 3 rotating at a speed adapted to the hardness of the rock and with a corresponding pressure. Cooling the cutting or Milling tools 3 are carried out by means of liquid or air rinsing via a rinsing head 7 on the drive shaft 15 and lines 12 through the hollow linkage with outwardly directed, spaced-apart outlet nozzles 8.
  • the milled material ejected into the annular gap 18 is mechanically or by a following suction device 9 ( see Figure 2) removed. In special cases, however, the cut material can also be sucked off through the hollow rod via the nozzles 8, line 12 and flushing head 7.
  • the device has the advantage that the hollow rod 1 in a rotating manner by the guide means 6, 6, arcuate, for. B. can be moved on the circumference of the shaft or section, the annular gap 18 being produced in the mountains 16.
  • the rotational movement of the cutting or milling arm prevents jamming during arc cutting.
  • the loosened cut material is removed mechanically or by a suction device from the annular gap 18, so that a direct pressure wave transmission to the outer rock jacket 16 can no longer take place when the inner shaft or section body is blown up.
  • the device is also advantageously suitable due to the ability to mill narrow arch slots, not only to produce natural stones as straight-edged blocks, but also as cylindrical blocks.
