Definitions

  • the invention relates to a method and a device for cutting, drilling and the like material-removing processing of rock, ores, coal, concrete or other hard objects by means of a pressure medium according to the types mentioned in claims 1 and 7, and a use of the method and the device.
  • the first-mentioned methods and devices have already proven themselves well, since they can also be used to work out long and narrow slits, bores and similar openings, for example from hard rock, and because the Devices can be formed relatively narrow and long.
  • the invention has for its object to further improve methods and devices of this type with simple means in terms of their functionality. So even with very hard rock with in particular hard crystal grains, even greater machining performance should be achievable. In addition, the device should work as little wear as possible. In other words, the speed of producing a slot of certain width, length and height should be increased and the processing costs should be reduced.
  • the invention enables the processing power to be increased by up to approximately 100%, depending on the type of object to be processed and the pressure medium and possibly coolant used.
  • the device works with low wear even in deep slots.
  • Fig. 1a to flow from the nozzles 5a ⁇ , ⁇ 5a of the nozzle head 3a beams 25a ⁇ , ⁇ 25a of pressure medium out.
  • water is used as the pressure medium, which is under a pressure of in particular between 800 and 3000 bar, for example 2400 bar.
  • the central nozzles 5a ⁇ , the central jets 25a ⁇ are directed at an angle of incidence ⁇ a to the main jet direction HR of approximately 5 o
  • the angle of incidence ⁇ a of the more widely spread jets 25a ⁇ is up to 27 °, especially 17 o .
  • These outer rays 25a ⁇ determine the width B of the slot 16 to be milled from the rock of the object 15. It has been shown that in some cases of machining in cross-section pin-like Formations 15a remain at the base 15b of the slot 16. This sometimes leads to the nozzle head 3a striking when it is moved in the main jet direction HR in order to make the slot 16 deeper.
  • the nozzle head 3a according to FIG. 1b is followed by a further nozzle head 3b.
  • This nozzle head 3b differs from the nozzle head 3a and its guidance in the following:
  • the central beams 25b ⁇ have an amount from about 0 o forming angle ⁇ ⁇ to the main beam direction HR, while the side beams 25b ⁇ of the pressure medium at an inclined angle ⁇ b of about 11 o to the main beam direction HR are directed. This results in a smaller spread angle than in the case of the outer jets 25a ⁇ of the first nozzle head 3a which determine the slot width B.
  • the nozzle head 3b - as indicated in broken lines and with the reference symbol 3 '- is deflected by a deflection E in the transverse direction QR (ie in the plane of the drawing of Fig. 1b).
  • the oscillating or oscillating movement takes place at a frequency between approximately 10 and 250 Hz.
  • the deflection E is 4 mm with a distance AB between the axes of the nozzle heads 3a, 3b of approximately 60 mm.
  • the inventive method allows a doubling to about 4 m / h.
  • the consumption of water as a pressure medium is approximately 50 l / min when it is fed through the feed lines 30a, 30b to the two nozzle heads 3a, 3b and ejected through the eight nozzles 5a, 5b thereof.
  • Fig. 2 is indicated schematically that the first nozzle head 3a with its feed line 30a in the transverse direction QR is not, the second and in particular lagging nozzle head 3b with its feed line 30b, on the other hand, is quickly moved back and forth about the deflection E in the transverse direction QR, as this is indicated by 3b ', 5b ⁇ ' and 30b '.
  • the two nozzle heads 3a and 3b are connected to one another by plates 23 such that the plates 23 are welded to the outer sides of the cylindrical nozzle heads 3a, 3b by the weld seams 23a, so that a chamber 23a is formed between them and the nozzle heads 3a.
  • the beam of rays 25g flows out between the jets 25a of the first nozzle head 3a and the jets 25b of the pressure medium of the second nozzle head 3b.
  • air under a pressure between about 1 and 10 bar is used as the coolant.
  • the coolant of the coolant jets 25g is a few 10 o C, in particular about 50 o C cooler than the pressure medium exiting through the nozzles 5a, 5b.
  • FIG. 3 and 4 schematically show a design for the deflection E of the feed line 30b or of the relevant nozzle head 3b:
  • the two feed lines 30a and 30b are each guided in a guide 44, 44a, which are held at a distance from one another by welded-on connecting rods 45, so that this holder forms an essentially rigid structural unit.
  • a tension spring 42 which engages on the one hand through an eyelet 41 on the component 40 and on the other hand via a holding pin 43 on the upper holding device 44, presses this holding device 44 to an eccentric cam 47, which is mounted by a drive unit 48, for example an electric motor, a hydraulic motor or a pneumatic motor, on a bracket 49, which is also fastened to the holding member or similar component 40.
  • the second nozzle head 3b commutes by an angle of for example 4 o to the first die head, which in particular along a straight path in the direction of movement BR moves away and narrow slots 16 without much waste of material eliminates.
  • the deflection E can also be caused by the action of a percussion piston can be achieved, as is the case with pneumatic or pneumatic hammers.
  • the invention is particularly suitable for the low-vibration clearing of rock or other hard ground, e.g. in large cities without vibrations and the associated damage to neighboring buildings, the foundations of new buildings are to be sunk deep into the ground.
  • the processing i.e. The clearing out of slots is not only precise and quick, but also avoids rock blasting and / or the use of pneumatic hammers.
  • the invention also contributes to environmental protection by reducing noise.
