Definitions
- the invention relates to a nozzle head of a high-pressure liquid jet device for processing a surface.
- a nozzle head comprises a media supply and at least two jet nozzles for producing a forwardly directed jet of high pressure liquid jet media.
- the nozzle head further comprises a nozzle holder for holding the jet nozzles and their fixation in a working position, based on the nozzle holder.
- the invention also relates to a high-pressure liquid jet device for processing the wall surfaces of open or closed channels, even of non-accessible channels for people.
- a surface to be treated refers to surfaces which have coatings or adhesions or other components to be removed on the surface which are to be processed by the device.
- the term "forward" refers to the basic orientation of the jet as viewed from the nozzle orifice on a surface to be machined. In front, therefore, is the half-space from the nozzle opening, in which the jet medium propagates as a free jet to the surface to be processed.
- the machining direction "forward” denotes the central axis of this half-space.
- High pressure liquid jet devices are used for a variety of different applications, such as cutting materials, removing body deposited coatings, such as paints, or removing unwanted deposits, contaminants, or soils, generally referred to herein as buildup Surfaces, especially on surfaces known in channels. It is also known that the medium can have solid components to enhance the abrasive action. For the various applications and the performance requirements associated therewith, various pressure ranges are contemplated in which the water jet devices are operated.
- pressures in the range of about 80 bar to about 6000 bar are used, with pressure ranges above about 500 bar are also referred to as maximum pressure.
- the pressure ranges of the high pressure and the maximum pressure overlap, the upper limit of the high pressure, in the currently conventional liquid jet devices at about 700 bar, far below the upper limit of the maximum pressure.
- the transition from the area of high pressure to the area of maximum pressure takes place against the background, even very dense and hard adhesions on the surfaces to be machined, for example on surfaces of a channel to remove and on Because of this increased effect of the medium to reduce the area-related amount of the necessary medium for processing.
- High-pressure liquid jet or similar device used hereinafter includes the configuration for high-pressure liquid jets, although the liquid jet devices for the two pressure ranges may differ in use cases and configuration.
- the amount of liquid per unit of time is of interest, which is provided by one, optionally also more than one pump of the device.
- liquid quantities of 8 to 40 l / min are usual, although different configurations of pump parameters exist for the different volume ranges.
- the limits and the available pumps may also vary with respect to the amount of liquid usable for the method and apparatus.
- a medium is brought by means of a working machine to a certain pressure and directed by flexible hoses or other media guides, such as pipes to a nozzle.
- the pressurized medium then emerges as a free jet from an opening of the nozzle.
- this free jet can be directed to the surface to be machined, where the beam in turn causes a locally limited abrasive effect on impact.
- multiple nozzles are used simultaneously, which can form a common beam or radiate in different directions.
- nozzles with multiple openings are known.
- the beam may be bundled or fan-shaped.
- a collimated beam has a substantially circular cross-sectional shape
- a fan-shaped beam is characterized in that the medium is spread in the form of a fan when exiting the opening, so that it strikes ellipse or line on the surface to be processed.
- nozzles in which the jet emerges in the form of the lateral surface of a cone. For an effective and / or targeted treatment of the channel surface, it is often necessary to vary the angle at which a nozzle is directed to the surface to be machined.
- nozzle heads are known which are pivotable.
- An object of the present invention is to provide a nozzle head for a high-pressure liquid jet device having two or more jet nozzles and such a device which enables alignment of the nozzle at the work site while maintaining or improving the applicability to the named fields of application.
- a nozzle head is proposed, the jet nozzles can be deflected together or separately in different directions, wherein the deflection in each case has a radial component.
- a changed angle of attack can be set to the surface to be machined for the rays of each jet nozzle, without pivoting the entire nozzle head.
- Such an adjustment can be made on site and is usually assisted by a camera with lighting on the nozzle head or other components of the processing device.
- the nozzle head with a plurality of jet nozzles allows a variation of the beam diameter of a full-circumjacent beam with simultaneous variation of the angle of incidence, so that the beam power is not or only slightly reduced.
- the nozzle head in addition to the jet nozzles also include a central main nozzle, for example, which is used depending on the type and extent of processing simultaneously or alternatively to the jet nozzles and can be moved in the known manner only with the nozzle head together.
- various of the known nozzle shapes can be used, depending on the requirements of the processing to be performed.
- the rotation of the Nozzle head as known from the prior art is possible with the nozzle head described in detail here.
- the media supply of the nozzle head is designed such that each jet nozzle has a separate liquid feed line, at the front end of which the jet nozzle is arranged.
- a distributor such as a pressure distributor, only a single jet nozzle.
- each jet nozzle By means of slot openings in the nozzle holder, one for each jet nozzle, each jet nozzle, all of which project through a respective slot opening, can be guided for themselves between a first and a second end position.
- the slot openings each have a radially extending component. This means that the slot openings do not run only as a circle segment about the axis of the machining direction, but the distances between the two end positions of a front end of a liquid supply line to the axis differ from each other.
- the deflection of the jet nozzle which can be performed by means of the slot profile, is realized for at least one of the jet nozzles by means of such a design of its liquid feed line, in which the front end of the liquid feed line is displaceable by means of a nozzle manipulator between the rest position of the jet nozzle and its end position.
- the term slidably includes suitable configurations of the liquid supply lines of the jet nozzles, in which at least the front end and with this the thereto fixed jet nozzle by means of the nozzle manipulator in the range of movement, which allow the slot openings, is movable. It is irrelevant to what extent the further liquid supply is moved with.
- the liquid supply line can be made stiff and moved in its entire length or from a defined, spaced from the front end point and pivoted.
- the liquid supply line may be tubular and the displaceability of the front end be realized by means of a liquid-conducting rotary joint or a hydraulic rotary feedthrough.
- Such hinges and rotary joints are known components in which a passage for a liquid is provided by the component to the respective degrees of freedom in the movement.
- the rotary joint is known to combine a rotation with the change of the angle and numerous angles of attack in the front half space or at least a meaningful section thereof can be set
- the rotary feedthrough allows only one rotation of the two interconnected by means of the rotary feedthrough lines.
- a pipe between rotary union and front end additionally a pipe offset or pipe angle, whereby with the rotation with the suitable position of the offset or the angle always a radial component of the displacement can be generated.
- the liquid supply can also be tubular and at least partially flexible, so that even with a fixed rear end, the front end of the movement of the nozzle manipulator can follow.
- the nozzle manipulator can be formed by a variety of components that are suitable to move at least the front end of the liquid supply and thereby fit into the available space and work reliably under the often very aggressive operating conditions.
- Such components referred to herein as positioning means, for example, may be an eccentric arranged between the liquid supply lines, a camshaft arranged between the liquid supply lines, a servo motor, at least one hydraulic or pneumatic cylinder or at least one press pad which can be filled with a pressurized gaseous or liquid medium is.
- a camshaft arranged between the fluid supply lines shifts one or more fluid supply lines outwardly away from the shaft by means of the cams during rotation.
- the design of the camshaft defines the two end positions per se and the possible displacements of the individual fluid supply lines between their first and second end positions.
- the position to be set for machining a surface can thus either vary continuously or be fixed by stopping the camshaft a certain position.
- an eccentric arranged on a shaft can cause the displacement of one or more fluid supply lines, but the variability of the movement is smaller.
- a high variability and precision of the displacement of the front end can be achieved with a servomotor or several of them, as with this targeted individual positions can be approached.
- a hydraulic or pneumatic cylinder or more thereof are used to realize the displacement of one or more jet nozzles, wherein the hydraulically or pneumatically in the cylinder initiated movement of the piston is used for the position control of a jet nozzle.
- suitable adjusting means By means of suitable adjusting means, the power transmission from the piston to a liquid supply can take place.
- a press pad or more may be used to move the front end of the liquid feed lines from a first end position to the second one.
- the state of the press pad changes between unfilled and filled.
- the press pad may also be arranged on the outside and surround the liquid supply lines. In this case, however, the motion sequence of the jet nozzles just described is effected by the transition from the filled to the unfilled pad. In certain applications, the movement can also take place in the opposite direction, from outside to inside, which is also feasible by both types of press pad.
- a combination of two press pads is, for example, to ensure a more precise positioning and fixing of the jet nozzles.
- a relative movement of the liquid supply to the press pad may be permitted by: the press pad is compliant in the region of contact with the liquid supply lines or has a lubricious surface.
- the force application of said positioning means should be either at the front end or between the front end and that portion of the liquid supply line, which, according to the above teachings, permits the displaceability of the front end.
- the nozzle manipulator comprises, in addition to the positioning means, further components for the movement or activation and control of the positioning means. The person skilled in the art will meaningfully coordinate the aforementioned alternative configurations of the nozzle holders, the liquid feed lines, the positioning means and the nozzle manipulator in order to achieve the nozzle arrangement and movement required for the application.
- an external pressing pad offers the possibility of fixing the nozzle head relative to adjacent walls, for example a closed channel, by pressing the pad against the walls as a result of the filling.
- the nozzle head may have one or more fixing pads which, unlike the press pads, primarily serve to fix the nozzle head against adjacent walls.
- fixing pads are used for channel robots in the DE 20 2014 000 026 U1 which is referred to herein with respect to the function and configurations of a fixation pad.
- Fixierpolster position a nozzle head or the entire processing device also with respect to a high recoil generated by the high-pressure jet and can be designed such that waste produced during processing can be flushed out.
- the Fixierpolster are filled with a pressurized gaseous or liquid medium and include the liquid supply lines. If these alone serve to fix the nozzle head, a force from a fixing pad on the liquid supply lines is to be prevented. According to one embodiment of the invention, they can also be used in conjunction with a press pad. In this case, two fixing pads are arranged one behind the other in the machining direction and at least one of them is designed as a positioning means of the nozzle manipulator for deflecting the front end of at least one liquid feed line, as described above for the outer press pad.
- Comparable to the fixing pad and a press pad may be formed in segments. This makes it possible to provide passages for the rinsing of the overburden of processing and / or to assign the segments to the individual liquid supply lines and thus to move the jet nozzles differently with different degrees of filling.
- the nozzle manipulator of the nozzle head has a torque generator for rotating at least the liquid feed lines with their jet nozzles.
- the torque generator is configured such that the torque that can be generated thereby is large enough to use the generated centrifugal force, the jet nozzles from one to the other To move to the final position.
- a torque generator is preferably a prime mover into consideration, such as a hydraulic or pneumatic motor or an electric motor, as with these the required torques to achieve and are suitable for the applications described.
- liquid supply lines and of the positioning means or the displacement can be limited to certain movements.
- the slot openings in the nozzle holder are to be matched to it.
- the described nozzle head is usable because of its variability in the design and the movement of the jet nozzles for the above-mentioned and other processing devices, for example for a high-pressure liquid jet device for working channel walls of open or closed channels by means of high-pressure liquid jets.
- a jet device comprises a nozzle head, which is arranged at the front end of the device, for generating at least one forwardly, hereinafter referred to as machining direction directed jet of a liquid jet medium, with a carriage for moving and positioning the nozzle head in the channel and with a media supply, for supplying the nozzle head with the high-pressure jet medium.
- the abrasive jet is directed in the channel direction or at an angle deviating therefrom by degrees so that an obstacle or an adhesion is removed, for the sections or even progressively processing.
- the device is moved by a trolley forward through the channel.
- an appropriate media supply for example, for water and possibly also for the solid particles and gas, so that neither the processing nor the movement hindered nor damaged the media supply.
- a fixing pad which can be filled with a gaseous or liquid medium under pressure is arranged at the rear end of the carriage and / or the nozzle head, which is inflated for activation by compressed air or a pressurized fluid and is designed such that that it fixes the position of the trolley and / or the nozzle head in the activated state by pressing the Fixierpolsters in the channel, without closing the channel.
- the nozzle head by means of this fixing pad and the carriage can be fixed without hindering the removal of spoil.
- the fixation pad is inflated by compressed air (pneumatic) or a pressurized fluid (hydraulic) so that it compresses in the canal.
