Definitions

  • the invention relates to a device for cutting and drilling in particular rock, ore, natural rock, concrete or the like or for processing objects with the aid of a pressure medium under high pressure of the type mentioned in the preamble of claim 1.
  • a nozzle head is deflected transversely to the direction of the jet of pressure medium emerging from a nozzle opening by means of a drive unit in oscillating movements.
  • Ultrasonic transducers, electromechanical transducers and also mechanically or hydraulically driven ones are used as drive units.
  • the nozzle head itself is mounted in bearings so that it can either be moved linearly or pivoted about a bearing shaft.
  • this bearing wears out quickly when working with oscillating movements of relatively high frequency, which are recommended for productive cutting.
  • the object of the invention is to improve the functionality of the device of the type mentioned at the outset.
  • it is particularly desirable to design relatively narrow devices, which also offer the possibility of working in long and narrow slots, bores and the like, for example in rock.
  • the device should have a long service life.
  • the purpose is to improve the functionality of the nozzle head with little manufacturing effort and little space. It is desirable to quickly process, for example, slot-like clearing of rock, flötz and the like. the like, in particular also of great hardness such as granite and marble.
  • part of the supply line is designed as a pendulum tube, on which the drive unit may engage via a clutch unit.
  • a "pendulum tube” is understood here in particular to mean such a supply part to the nozzle head which executes such a movement during machining that the nozzle head executes a back and forth or a circular or even oval movement in particular in such a plane, which essentially runs at right angles to the axis of the nozzle or center nozzle. This "oscillating" movement in lateral view deflects the beam laterally.
  • the beam Due to the "oscillating" or oscillating movement, the beam describes a straight or curved line when it strikes the object to be processed (provided that a point of impact is assumed and the device is assumed to be at rest other than the "oscillating" supply part).
  • the drive unit is supported on a control line which extends essentially parallel to the supply line.
  • the control line directs the energy source to excite the drive unit, e.g. also mechanical rotary movements i.e. kinetic energy, to the drive unit and has a guide for the pendulum tube, which can also be formed by the drive unit itself.
  • the drive unit e.g. also mechanical rotary movements i.e. kinetic energy
  • the pendulum tube itself can be made relatively rigid and can be coupled to the feed line in particular via a bendable and / or pivotable coupling. It is recommended if the pendulum tube is also connected to the control line via one or more springs, so that the drive is transmitted by the drive unit via the spring in even better oscillating movements. However, it is also possible to use a pendulum tube that is bendable, but still sufficiently rigid, so that the nozzle head is adequately supported and guided by the pendulum tube itself. The latter alternative is even preferred; the nozzle head is attached to the free end of a bendable high pressure hose that can be expanded somewhat under internal pressure.
  • the nozzle head has several nozzles at such different angles of attack that the axes of the same are not in a common straight plane.
  • the nozzle axes should be offset from the longitudinal axis of the nozzle head.
  • a combined jet of the pressure medium is emitted from the nozzle head, the individual jets emanating from the individual nozzles, in contrast to the device mentioned above, not in a straight plane, in the manner of a fan, but in one or more curved and / or kinked planes run.
  • a nozzle head with a center nozzle and a side nozzle that is laterally offset and inclined outwards from the jet direction of the center nozzle offers particular advantages. If the nozzle head is in a e.g. circular path moves, the individual beams also sweep circular paths that partially overlap and, when the device moves transversely to the pendulum tube or high-pressure hose and to the control line, better work out a slit-shaped path from the irradiated rock or rock.
  • no nozzles are screwed onto the face of the nozzle head.
  • the nozzle head has an elastomeric cover on the front are provided and insert nozzles are inserted from a nozzle chamber into connecting channels of the nozzle head, which is made in particular of hard metal.
  • the pressure medium inevitably presses the respective insert nozzle against stops which limit the connecting channels and form the transition points to the nozzles.
  • the insert nozzles nor their receptacles in the nozzle head have to be threaded, so that insert nozzles made of sapphire can also be used.
  • the design of the nozzle head according to the invention can be used not only in the device according to the invention with a pendulum tube and, in particular, in parallel control line, but also in a device known per se (DE-OS 34 10 981), in which a flexible or bendable high-pressure hose as a feed line to the nozzle head, which is caused by the ejected pressure medium itself - without a drive unit - in lashing movements or by a combination of a driving force from the pressure medium flowing through itself and by a drive unit in circular, shock-like and / or wave-like movement.
  • the wavy movement of the high pressure hose (in a plane running through its axis) is extremely beneficial.
  • a pipe as a pressure medium supply line 12 is rigidly connected via connecting webs 36 to the control line 31, which is also designed as a pipe; the tube 12 and the control line 31 run parallel.
  • a coupling 11 is attached, which connects the pendulum tube 30 with the tube 12 connects so that the pendulum tube 30 around the articulation point of the clutch 11 in oscillating motion - as indicated in broken lines - by, for example, the pivot angle ⁇ can be brought.
  • a high-pressure hose HP hose
  • HP hose high-pressure hose
  • the pendulum tube 30 is supported on the guide 6, which protrudes laterally from the control line 31.
  • a nozzle head 3 At the free end of the pendulum tube 30 there is a nozzle head 3, on the front side of which at least one nozzle is arranged, through which pressure medium can be expelled in the direction of the rock 15 under high pressure during operation.
  • the oscillating movement of the pendulum tube 30 and therefore of the entrained nozzle head 3, which oscillates to the right and left by the pivoting angle ⁇ , is caused by a drive unit 32, which is attached to the control line 31 and by an energy source, for example kinetic, electrical, electronic. Magnetic, pneumatic or hydraulic energy can be driven, which is guided through the control line 31 to the drive unit 32.
  • a plunger 33 of the drive unit 32 briefly pushes the pendulum tube 30 in the direction facing away from the control line 31.
  • a spring 34 is tensioned, which on the one hand prevents the pendulum tube 30 from being deflected too far, and on the other hand pulls the pendulum tube 30 back in the opposite direction, that is to say to the control line 31.
  • the pendulum tube 30 between the coupling 11 and the nozzle head 3 is of sufficient length to cause sufficiently wide deflections on the nozzle head 3, even by slight deflection by means of the tappet 33 of the drive unit 32, because this results in the effectiveness of the pressure medium when it strikes on the rock 15 is improved.
  • the drive unit 32 acts much further than the spring 34 in the direction of the coupling 11 on the pendulum tube 30.
  • the sensor element 35 is in particular an electrical one, the electrical signal lines of which are led through the control line 31 to a control unit (not shown here).
  • the HD hose due to its bendable and even slightly flexible design using elastomeric material, such as rubber, which even allows a certain amount of inflation when the pressure medium is passed through, oscillates, as is shown schematically in FIG. 12 are shown.
  • the HP hose 30 may be at rest, while at the outer end D, to which the nozzle head 3 is fastened, one that is reciprocating in the plane of the drawing oscillating movement, but actually - as will also be explained with reference to FIG. 13 - executes a circular movement in such a plane that runs practically perpendicular or normal or at 90 ° to the nozzle axis.
