Definitions

  • the invention relates to a coating device for the inner coating of pipes and channels with a multicomponent plastic, which can be moved in the pipe via a supply hose package which also serves as a pull line and has several medium lines, and which maintains a spacing that slides on the inner wall of the pipe Mixing material has on the inner wall discharge distributor.
  • the plastic is applied via carriages or pipe coating devices which can be moved in the pipe or in the channel.
  • This coating device is connected via a towing or train line to a supply vehicle or supply point on the earth's surface in such a way that the individual plastic components can be carried separately to the coating device. They are warmed up.
  • the components of the plastic are mixed intensively in the mixer and discharged onto the inner wall of the pipe, for which both the centrifugal process and, above all, the spraying process are known.
  • the invention is therefore based on the object of providing a coating device which ensures a coating which is uniform and of the same thickness in the tube even during the process.
  • train line has longitudinally spaced sliding elements which project beyond the outer wall of the train line and which are assigned to relief gliders distributed over the length of the train line.
  • the damaging rubber band effect cannot occur because - as already mentioned - the coating device can be moved in the longitudinal direction of the tube evenly and without any build-up, including the train line.
  • the coating device can be moved in the longitudinal direction of the tube evenly and without any build-up, including the train line.
  • there can be no harmful expansion or compression because the entire train line is moved back and forth evenly on the inner wall of the pipe.
  • This has great advantages in particular if postprocessing is necessary for some reason, for example in the area of sleeves, because the surveillance television camera has determined accordingly.
  • the sliding elements as such can be easily moved or pulled over non-smooth inner tube walls because the compensating sliding elements are present.
  • the relief sliders are each designed as a holder that surrounds the train line in an annular manner and accommodates a plurality of sliding elements that are distributed over the circumference.
  • Relief gliders of this type ensure that the hose lines are supported and guided, irrespective of which area of the respective train line is currently coming into contact with the inner tube wall. They can be pushed as ring-shaped relief sliders on the train line into the position where they are needed, whereby a uniform distance is usually chosen over the length of the train line. It is only important that, depending on the dimensions of the train line or the pipe, there are no sagging areas, which in turn result in friction losses would.
  • a further expedient embodiment provides that the holder is designed in several parts, preferably in two parts, the two part holders being connected to one another via a pivot shaft parallel to the train line axis and a releasable fixing bracket.
  • This gives the possibility to slide the partial brackets or the entire bracket back and forth on the train line if necessary and to bring them into a position that is just expedient. Assembly is also easier because the bracket or the partial brackets equipped with the sliding elements are easy to assemble. When the fixing clamp is fixed or swiveled, the respective holder with the sliding elements is then exactly in the position which is considered to be expedient.
  • the mountings with the sliding elements or the relief glides can be brought into a position that is optimal for the respective application.
  • the relief gliders are designed in such a way that all-round guidance for the train line is ensured, this being achieved in that the sliding elements are arranged at a spacing on the holder which ensures all-round support or guidance.
  • the sliding elements as balls made of hard plastic, preferably solid material balls. These balls or sliding elements roll evenly on the surface, even on a rough surface of the pipe, and thus ensure that the coating device is pulled evenly through the pipe or the duct with the slightest friction losses. This material is also insensitive to contamination in the pipes, but also largely to chemical components. Continuous use can thus be realized.
  • the sliding elements forming a first and a second sliding ring are arranged at the ends of the cylindrical holder.
  • the brackets With such cylindrical brackets, it is possible to make the distance between the individual brackets larger because the bracket as such forms a type of carriage on which the respective section of the train line can be supported and is accordingly guided. This design also prevents any directional problems when guiding through the pipe or the channel, so that the running of the coating device is additionally promoted.
  • the invention provides that a rotary bearing is provided between the train line and the connection to the base body, which is arranged and designed to prevent the train line from twisting.
  • this prevents twists existing on the train line or occurring there also from being applied to the tracked and redrawn device, ie. H. can transfer the coating device. Rather, it is ensured that this coating device is completely unaffected by this and is ultimately guided only along the spacers along the inner wall of the pipe, favored by the relief gliders that support and guide the train line. This also ensures that the coating devices are arranged exactly in the center.
  • the invention provides that the sliding elements are held by U-shaped brackets , wherein the flanks are preferably telescopic. With appropriate spring loading, it can be ensured that the individual flanks ensure that the sliding element assigned to them is always in contact with the inner wall of the pipe and thus guides the entire system, but in particular the corresponding section of the train line.
  • the stratification device as such further contributes to the uniformity of the coating application, in that the distributor is preceded and / or assigned a metering unit and a mixer which has a spray head provided with nozzles, the nozzles being assigned a basket-shaped, rapidly rotating distributor, into which the nozzles are discharged and in which the mix is in turn designed to guide the pipe inner wall.
  • the components supplied in different quantities can be fed into the mixing process in a precisely controlled manner by the metering unit. These precise quantities to be measured are then fed via the spray head and the nozzle onto the rapidly rotating distributor and from there onto the inner wall of the tube, and are mixed intensively, so that a uniform material reaches the inner wall of the tube.
  • the rotating distributor rotates at around 15,000 rpm, so that the mixed material is literally hurled or applied onto the inner wall of the pipe at the appropriate speed and adheres there and is distributed so that there is a smooth wall.
  • This movement and the sprayed-on material result in intensive mixing, in particular the necessary final mixing of the two or more components.
  • Compressed air is required both for discharging the mix and for rotating the distributor.
  • the existing compressed air is also used for control and regulation at the same time, in that the metering unit is equipped with air-controlled check valves.
  • the spray head has nozzles associated with the ends of the medium lines and the compressed air line, which nozzles are designed to be adjustable in terms of direction and quantity. Accordingly, when coating with polyurethane, there are three nozzles, two for the medium and one for the air, whereby the material can be specifically applied to the mixing cone via these nozzles because they can be adjusted in terms of direction. As a rule, the setting is carried out by hand, since the direction of the discharge jets can be precisely specified based on experience and calculations. Depending on the medium composition or the amount, it is with the help of the invention it is also possible to correct the direction of the discharge jets once set.
  • a particularly favorable mixing can be achieved if the discharge jets of the nozzles are set crossing in front of the mixing cone on the central axis. With the support of compressed air and this targeted guidance of the discharge jets, perfect mixing of the media is ensured, which is then discharged as a mix via the distributor and applied to the inner wall of the pipe.
  • a further possibility for correction is given if the mixing cone is connected to the rotating distributor in a detachable manner and at a distance from the nozzles. This can be achieved, for example, by making the round steel holding the mixing cone telescopic, or if it can be fixed at several points by means of screws and / or pins, in order to change its distance from the nozzles.
  • the material to be mixed After leaving the mixing cone, the material to be mixed is transported uniformly and then discharged, since the rapidly rotating distributor or the hat-shaped cover from the mixing cone and the bottom diagonally outwards and to the edge with discharge slots that run diagonally to the central axis of the distributor, the 0.5 to 5 mm are wide. These discharge slots let the mixture that is sliding and mixing continues to emerge, so evenly that a kind of veil forms on the inner wall of the pipe when it is turned quickly and ensures even distribution and practically drip-free distribution.
  • the advantage is that, especially with the narrow cross sections of such pipes, despite the small Distance of the distributor to the pipe inner wall is still an even and safe distribution possible.
  • the rapidly rotating distributor preferably has three discharge slots of this type which are designed to run obliquely to the central axis of the distributor and which have a width of 0.5 to 5 mm.
  • These discharge slots which - as mentioned above - are designed to run towards the central axis, allow the mix to pass through uniformly, the oblique slots with the narrow gap width ensuring that the fast-rotating distributor has sufficient stability and yet the mix practically has that the entire wall can be discharged at a certain point, so that the entire mix is really discharged before it can harden in any form.
  • the hat-shaped cover is detachably connected to the turntable, for example by screws. This turntable is driven by the air motor and ensures the aforementioned rotational speed of 15000 rpm.
  • the spray head is equipped with an obliquely discharging nozzle which is arranged to discharge in the adapted angle of the basket-shaped distributor. Then you can do without the mixing cone. This specifies a relatively short path for the components to be mixed or the premixed components, but this is sufficient because the distributor rotates very quickly and the material is kept in motion accordingly. The polyurethane mixture then exits through the slots or discharge slots in the distributor and is applied evenly to the inner tube wall.
  • Such coating devices can only be used successfully in the long term if they can also be operated at intervals. This means that the system must be shut down from time to time in order to ultimately ensure monitoring or to rectify any errors that occur as soon as possible.
  • the coating device is then moved back in the old direction in order to repeat the coating.
  • the nozzle has an inner bore in the spray head, in which a cleaning needle is arranged so as to be displaceable into the discharge opening.
  • the cleaning needle is operated via the air motor, the holder of the cleaning needle being connected to a piston rod, which is assigned to a compressed air piston, via a plunger running axially in the base body.
  • the plunger and the piston rod and then the plunger and thus also the holder with the cleaning needle are thus pushed in one direction or the other over the compressed air piston in order to clean the inner bore in the nozzle.
  • the stroke of the compressed air piston can be changed or adapted to the conditions, since the stroke of the compressed air piston can be adjusted via an adjusting thread on the piston rod and / or an adjusting bush.
  • an air nozzle is assigned to the outlet opening and thus to the tip of the cleaning needle, said air nozzle being arranged at a right angle to the spray jet of the nozzle and being directed towards the outlet opening.
  • the cover of the distributor is designed as a centrifugal hood which has sets of inclined bores which are arranged at a distance in the longitudinal direction and run outwards from the inclined inner wall.
  • These oblique bores and sets of oblique bores are assigned to grooves which run radially and in which the respective oblique bores end.
  • the oblique bores start from the inclined inner wall of the centrifugal hood, so that when viewed from the nozzle they get an ever greater length due to the increasing thickness of the centrifugal hood. Due to the resulting bevel, the mixing process takes place evenly and the mixed components are gradually discharged through the corresponding oblique holes on the inner wall of the pipe.
  • the individual oblique bores are expediently acted on in such a way that the spray jet of the nozzle is aligned with a spray jet target formed at the level of the outermost oblique bore set.
  • the mixture then flows in the direction of the, unless it is discharged directly through the inclined bores of the first set Bore sets with the shorter paths, from where the material is then also brought outside and discharged onto the inner wall of the pipe.
  • it is possible to create a wide veil, which contributes to a uniform coating but also to a faster coating process.
  • the invention is characterized in that a method is created with which even small diameter pipes with, for example, 100 or 150 mm diameter can be coated evenly and safely despite the narrow cross-sections, namely with polyurethane or a similar plastic that simultaneously Pipe wall stabilized and any leaks eliminated.
  • the coating device required for this consists of a tubular base body which is held at a distance from the inner tube wall by means of spacers in the form of spacer springs and which is moved uniformly over the train lines and while maintaining the centered position through the pipe without any influence by the train line or the Centering of the tubular body.
  • the material i.e.
  • the components of the polyurethane and also the compressed air are fed via the medium line to the fixed spray head, which sprays the individual media specifically onto the inner wall of the fast-rotating distributor or, first of all, onto the mixing cone, which is attached to the fast-rotating distributor.
  • the intensive mixing then ensures a uniform application of the mixture led out of the discharge slots of the distributor. It is particularly advantageous with the method according to the invention and the coating device according to the invention that small dimensions are available which enable use in the cramped conditions in such pipelines or pipes.
  • the entire system ie in particular the spray head and also the distributor, are blown free using the existing compressed air, so that for the next coating process processing operation, the system or the coating device is immediately available again.
  • the advantageously uniform movement of the coating device over the routed train line contributes significantly to the fact that the coating is optimally the same both in terms of the thickness and of the surface over the length of the pipeline or the channel. Jerky movements are excluded and at the same time it is ensured that the hose line or the train line is protected and protected against slitting and other loads even during long-term use. With the appropriately routed train line, it is easily possible to coat lengths of 150 m or even more in one operation.
