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 in such a way 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 invention has for its object to improve the functionality of the device of the type mentioned in the introduction.
- it is particularly desirable to design relatively narrow devices, in which there is also the possibility of working in long and narrow slots, bores and similar openings, for example in the 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.
- Fast processing is desirable, for example, slit-like clearing of rock, flötz and the like. the like, in particular also of great hardness such as granite and marble.
- the invention is characterized in claim 1. In any case, part of the supply line is designed as a pinned 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 when 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. 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 groove 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 supply line in particular via a bendable and / or pivotable coupling. It is advisable 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, which is bendable but still sufficiently rigid, so that the nozzle head is sufficiently 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 thereof 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 in the introduction, not in a straight plane, in the manner of a fan, but in one or more curved and / or kinked Levels.
- 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 a slit-shaped path out of 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 onto stops which limit the connecting channels and form the transition points to the nozzles.
- the insert nozzles nor the receiving devices of the same in the nozzle head must be provided with a thread, 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 a circular, impact-like and / or wave-like movement.
- the wavy movement of the pressure hose (in a plane running through its axis) is highly beneficial.
- Figure 1 is a schematic plan view of a device according to the invention.
- Fig. 2 is a schematic section according to II-II of Fig. 1;
- FIG. 3 shows a schematic top view according to FIG. 1 of another embodiment of the device
- Fig. 4 is a front view of a nozzle head and 5 shows a partial section VV through the nozzle head according to FIG. 4;
- Figure 6 is a partially broken plan view of an embodiment of the nozzle head in operation.
- FIG. 7 shows a side view of the device according to FIG. 6 in partial section
- FIG. 9 is a partial view of another embodiment of the device.
- FIG. 11 shows an enlarged detail from FIG. 9;

- Fig. 14 is a schematic partial view of an alternative embodiment of the device of Fig. 9 and
- FIG. 15 shows a detailed view (partially broken away) of part of the device from FIG. 14
- a pipe as a pressure medium supply line 12 is rigidly connected via connecting webs 36 to the dam line 31, which is also designed as a pipe; the tube 12 and the control line 3.1 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 coupling 11 in oscillating movement - as indicated in broken lines - by, for example, the pivot angle ⁇ can be brought.
- a high-pressure hose HP hose
- HP hose can also be installed between the tube 12 and the pendulum tube 30, for example in accordance with FIG not prevented.
- the pendulum tube 30 is supported on the guide 6, which projects laterally from the control line 31. 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.
- a drive unit 32 which is attached to the control line 31 and can be driven by an energy source, for example kinetic, electrical, electromagnetic, pneumatic or hydraulic energy, which through the control line 31 to Drive unit 32 is guided.
- 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 prevents the pendulum tube
- 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 jacket-like wrapping thereof is recommended, as indicated by the dash-dotted lines 40.
- the drive unit 32 is arranged relatively close to the clutch 11.
- a drive rod 33a forms a relatively long arm between the free end 33c pressing against the pendulum tube 30 and a pivot axis 33b, about which the drive rod 33a and the actuating arm 33d connected in one piece and offset by approximately 90 ° can be pivoted when it is driven by the drive unit 32 is driven to a certain extent in a direction parallel to the control line 31 (counterclockwise).
- the actuating arm 33d is designed to be several times, in particular four times shorter, than the drive rod 33a, only a slight movement of the free end of the actuating arm 33 ⁇ in the direction of the control line 31 leads to a substantially greater movement of the free end 33c of the actuating rod 33a in one transverse to this direction. Since with at high pressures of, for example, 2000 bar, the pressure medium conducted from the pipe 12 to the nozzle head 3 Pendulum movement of the pendulum tube 30 is not inhibited because the coupling 11 acting as a pendulum joint may become too rigid, it is advisable to conduct the pressure medium via a bendable high-pressure (HP) hose as a connecting line 41 from the tube 12 to the pendulum tube 30.
- the connecting line 41 forms a coupling. It is led out of the tube 12 via connecting sleeves 42 and 43 and into the pendulum tube 42.
- the nozzle head 3 is essentially rectangular in plan view, but it can also be essentially cylindrical.
- the nozzle head according to FIG. 5 is provided on the front outer or front surface with an elastomeric coating layer 19 made of rubber, which extends both over the two outwardly inclined front surfaces 21, 22 and over the central end surface 23 , which runs at right angles to the axis 25 of the nozzle head 3, which is made of hard metal.
- the chamber 7 On the other side of the nozzle head 3 is the chamber 7, on the annular side surface of which a connection piece 20 is arranged, by means of which the nozzle head 3 can be screwed onto the coupling member 1c of the pendulum tube 30 according to FIG. 8. If medium under pressure flows through the pendulum tube 30 into the chamber 7, it presses the cylindrical insert nozzles 17 made of sapphire onto the ends of the connecting channels 5 * b, which the chamber 7 with the nozzle outlets 5 spread outward in relation to the nozzle head axis 25 Connect a via the cylindrical nozzles 5a and the nozzle cones 5b.
- the diameter of the nozzle outputs 5 * a is smaller than the diameter of the connecting channels 5 * b, so that such stops or shoulders 27 are formed for the insert nozzles 17.
- the diameters of the nozzles 5a are considerably smaller than the diameters of the nozzle outlets 5 * a.
- the nozzle cones 5b open from the nozzles 5a in the direction of the nozzle chamber 7.
- the insert nozzles 17 are as close as possible to the end face in the area of the coating Layer 19 of the nozzle head 3 brought up, that is to say that the distance D between the shoulders 27 and the boundary surface between the hard metal body of the nozzle head 3 and the coating layer 19 is chosen to be sufficiently large that there is no risk of breakout even at high pressures of the medium .
- the two nozzle outlets 5 * a 1 and 5 * a 3 end on the flat end surface 23, while the two nozzles 5 * a 2 and 5 * a 4 each end on one of the inclined front surfaces 21 and 22, respectively.
- the axis 26 of the connecting channels 5 * b and thus of the nozzles 5a are arranged at angles of incidence ⁇ in relation to the nozzle axis 25. 4 clearly shows that the axis 26 1 is also inclined with respect to the axis 25 of the nozzle head 3, which is not to be expected without further ado in FIG. 5.
- the pressure medium While the pressure medium is still compressed to the nozzles 5a via the nozzle cones 5b tapering at the spreading angle ⁇ , the pressure medium, in particular water, relaxes behind it first behind the area of the nozzles 5a and then outside the nozzle head 3 and its coating layer 19 In contrast to Fig. 6/7, the single beam should remain "compact" as far as possible, rather than diverge. Therefore the nozzle head 3 is as close as possible, e.g. up to a few centimeters, brought up to the rock.
- the pressure medium in the direction of the arrow passes from the pendulum tube 30 into the chamber 7 and from there out of the nozzles 5a out of the nozzle head 3. From a pressure of about 250 bar, the oscillating nozzle head 3 swings back and forth between the stops 4 even more or less quickly, even without a separate drive unit 32, so that a "milling" effect in the rock 15 or the like is achieved without contact between the nozzle head 3 and the rock 15 exists.
- the device has a pendulum tube 30 as a feed line, here in the form of a slightly resiliently flexible HP hose, with a nozzle head 3 and nozzles 5a on the end face, and a guide 6 with stops 4 and springs in the form of spring-elastic buffers 4a.
- this preferably has a guide 2 which, together with the nozzle head 3 and in cooperation with the guide 6, leads to a striking or high-frequency movement Vibration of the pendulum tube 30 and the nozzle head 3 between the stops 4 according to the pivot angle ⁇ leads.
- the pendulum tube 30 is preferably provided with reinforcing sleeves la in the area of the stops 4.
- the cutting width C can be set so that the guide 6 with the walls 14 holding it can track the cut 16.
- the pendulum tube 30 oscillates around the coupling 11 with the pressure medium supply line 12.
- the pendulum tube 30 can also be a rigid tube, provided that it performs the desired pendulum movement, but there is a certain elasticity to achieve "whip-like" deflections cheaper.
- a coupling 11 is used to connect a pressure medium line 12.
- the stops 4 can also consist of a resilient Ma material such as rubber. With these stops 4, a longer service life compared to an embodiment without such stops 4 is possible.
- the guide 6 can be supported on the walls 14, which are connected by straight (FIG. 7) or curved (FIG. 8) end walls 13, but it can also have other shapes, for example a sieve-like reinforcement, through which the material removed during the cutting process can flow off with the medium.
- the guide 6 can be fastened with the screw bolts 13a.
- the elongated structural unit which is only interrupted at the interruption points ü in the illustration, but in practice is continuous, is composed of the following parts:
- the pressure medium supply line 12 is designed as a straight steel tube and extends from the connection point 1b for connecting a pressure medium line to the coupling 11 parallel to the control line 31, which is likewise designed as a steel tube, and is welded to it via the connecting webs 36.
- a rotatable shaft 102 is mounted within the steel tube of the control line 31 and can be driven by a hydraulic motor 101 at the end shown on the left in FIG. 9 and is connected at the other end projecting from the free end of the control line 31 to an eccentric element serving as a drive unit 32 .
- the clutch element 103 When the shaft 102 rotates about its axis, the clutch element 103 is moved in a circular path by the eccentric element acting like a crank; it also takes the connector lc at the free end of the bendable pendulum tube 30 in the form of a to some extent even inflatable, ie flexible, high-pressure hose, so that the nozzle head 3, which is interchangeably screwed onto the connector lc, rotates a circular with the rotation of the shaft 102 Performs movement. Corresponding circular paths sweep the jets 5b 1 , 5b 2 of the pressure medium emitted by the nozzle head 3, as will be explained in more detail with reference to FIG. 13.
- the motor 101 can drive the shaft 102 and therefore also the nozzle head 3 at a frequency between 1500 and 10000 rpm, ie between 25 and approximately 167 Hz.
- FIG. 10 which shows a partial section XX according to FIG. 9, legs 6a of a bow-shaped guide 6 extend on both sides of the control line 31 with the shaft 102 mounted therein.
- the two legs 6a are connected at the bottom by a web 6b, so that the circular or oval movement path of the HD hose serving as a pendulum tube 30 can also be guided.
- the free ends of the legs 6a are welded to the sides of the extension piece 100, which serves to receive the sensor element 35 and a line 35a leading to it.
- the sensor element 35 can be movable in the longitudinal direction of the extension piece 100 in order to actuate a contact when striking a surface.
- the sensor element 35 can also be rigidly connected to the spike-like extension 100; in any case, the sensor member 35 should protrude in the longitudinal direction LR of the lancet-like, elongated device over the nozzle head 3, in order to ensure that it is protected against striking against solid objects on the end face.
- the guide element 6 which surrounds the "oscillating" HD tube 30 on a circular path in a bow-like manner should leave such a free space between the mutually facing sides of the legs 6a that the HD tube 30 is not hindered in its path of movement, which is that of the eccentric element trained drive member 32 is caused, surprisingly, namely, that the HD hose vibrates due to its bendable and even slightly flexible design using elastomeric material such as rubber, which even allows some inflation when passing the pressure medium, such as they are shown schematically in Fig. 12.
- the clamping point A which corresponds to the coupling 11 of FIG.
- the HP hose 30 may be at rest, while at the outer end H, 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.
- FIG. 11 in which only the outer end of the high-pressure hose 30 facing the nozzle head 3 is moved around an intended center in the circular path and various positions, such as those in solid (30) and in interrupted (30 ') and in dash-dotted (30 ”) positions, there are actually antinodes E and F as well as oscillation nodes B and G.
- Suitable prints are between 1500 and 2500 bar.
- the design of the nozzle head 3 is a means of setting optimal conditions depending on the object to be machined or removed in connection with the movement of the nozzle head 3.
- the nozzle head 3 is provided with a central nozzle and with two side nozzles.
- the center nozzle directs a center jet 5b2 in the longitudinal direction or axial direction of the nozzle head 3, while the side jets 5b 1 , 5b 3 are offset by an angle of attack ⁇ of approximately 20 °.
- the rays 5b 1 5b 2 and 5b 3 essentially hit the surface of the rock 15 or the channel-shaped “cutout” 16 that has already formed in a punctiform manner.
- these points of incidence of the rays 5b 1 , 5b 2 , 5b 3 also correspond to the interrupted circles K 1 , K 2 and K 3 of FIG. 13 with the frequency between approximately 25 and 167 Hz guided, so that the material of the rock 15 is almost knocked out in order to mill the channel 16 out of the rock 15 in accordance with the width C of the total area covered by the rays.
- a beneficial effect is that in the course of the feed movement of the device in the direction of arrow Y according to FIG.
- Figs. 14 and 15 The alternative to the device of Fig. 9 is shown in Figs. 14 and 15.
- the eccentric element or drive unit 32 is not a crank piece, but rather the shaft end 102a bent at an angle of approximately 10-25 ° to the longitudinal axis of the shaft 102, onto which a bushing as an eccentric element or drive unit 32 is attached and fastened.
- This Buchs ⁇ is firmly connected via a rigid arm serving as a coupling element 103 to the connector lc, which is located at the end of the high-pressure hose 30 and is fixedly attached there by means of a connecting sleeve 30a.
- the nozzle head 3 is not shown in FIG. 15.
- the shaft 102 is supported at the end of the control line 31 - a tube - by means of a bearing 31b, so that the shaft end 102a rotates about the axis of rotation determined by the bearing 31b and due to the angle also gives the connector lc and the nozzle head 3 an oscillating movement.
- a radially projecting arm 11a is attached to the coupling 11 in a rotationally fixed manner, which abuts a stop 31a on the control line 31 and thereby prevents the thread of the coupling 11 from becoming loose during the oscillating bwz. commuting movement loosening of the HD hose 30 or even unintentionally unscrewed.
- the arrangement of the connector lc to the eccentric offers a further variation. If a further part of a bendable high-pressure hose 30 is installed as an “additional” pendulum tube between the connecting piece 1c and the nozzle head 3, then the whipping nozzle head movements are intensified. The mechanical and hydraulic alternating stress of the material to be processed is favored.
- the device can not only be used for cutting and / or drilling rock 15 in open quarries, but also in underground mines, for example in salt deposits for salt extraction or in coal seams to break out the coal or also to expand the passages to better deficient seams to make it accessible. Also tunneling for e.g. underground traffic routes are thereby to be managed. It can also be used for cleaning runways, walls and the like, for removing road marking paints, for cleaning oil tanks or power station tanks or for cleaning ship walls below the waterline, namely for removing mussels, barnacles etc., and for roughening road surfaces . This gives the specialist further possible uses.
