Definitions

  • the present invention relates to a device and a related use for coating and / or Decoating pipes with large diameters.
  • these are typically walkable pipes with a Minimum diameter of approximately 1.50 m, preferably of 2 meters.
  • the maximum diameter is usually 7 to 8 m, because of maximum pipe diameter to be achieved through the practical Conditions of the manufacturing process is limited. Therefore are currently pipes with a diameter of more than 8 m not manufactured.
  • Pipes are coated to protect them against harmful influences to protect against damage. For example, it is an anti-corrosion coating. Furthermore Coatings applied to the inside of the pipe to the Flow rate of liquids in the pipe increases positively influence.
  • a typical coating material is a Epoxy resin, which is suitable in the composition on it is coordinated which liquids or gases through the pipe to be passed through.
  • Another example, which one according to the invention by means of the device on the Inner pipe wall is a mineral coating, e.g. a cement. The latter is used for drinking water pipes on the Applied inner tube wall. Mixtures also come from minerals and epoxy resins as coating material in Consideration.
  • Walkable pipes of the type mentioned are in accordance with State of the art coated from the inside by a person the pipe runs through and manually, for example by means of a Spraying the layer onto the inner wall of the pipe. This procedure is tedious, especially with comparatively small pipe diameter and beyond the coating result is not always uniform. Should such a pipe inner wall is decoated, i.e. before applied old coating removed or from there deposited layers are freed, this is what happens also laboriously manual, typically with one Sandblasting or with a water jet that is under high Pressure is sprayed on the wall. Old coatings in large Pipes often contain tars, solvents and asbestos fibers. If such pipes are decoated, they are on the Decoating involved these people exposed to hazardous materials. It follows hence the need for decoating without the use of people pipe wall to be decoated directly, i.e. through a Device.
  • the object of the invention is the coating and / or Mechanizing stripping of large pipes, in particular to protect people from the harmful effects of to protect hazardous substances as well as the Working conditions and the coating or To improve the stripping result.
  • the claimed device has in one embodiment a supply unit for the introduction and forwarding of Coating material and / or stripping material in one Pipe on.
  • Pipe in the sense of the invention is to be understood to mean that it is a cavity open at least on one side, the cross section of the cavity can be shaped as desired.
  • the supply unit is a Container for coating or stripping material, which is outside the pipe to be coated or stripped and around one or more pumps, which the corresponding Materials or liquids through one or more hoses to the application unit belonging to the device.
  • the supply unit is only Connected to the application unit via hoses. This If the hoses are long enough, this prevents that Storage of coating or stripping material in the The possible applications of the Device limits due to the volume so claimed.
  • the application unit is intended to be used by the Supply unit introduced coating materials and / or stripping materials on the inner tube wall to apply or to let act.
  • the Supply unit introduced coating materials and / or stripping materials on the inner tube wall to apply or to let act.
  • it is is a high pressure nozzle through which the Sprayed coating materials and so on the Pipe inner wall are applied, or the Stripping materials at such high speed on the Hit the inner wall of the pipe so that an abrasive, adjusts erosion effect.
  • it is a Water-sand mixture or a flowable coating material, which are sprayed through the application unit.
  • the application unit attached to a movement unit. The latter thus enables the application unit to be moved in a pipe.
  • it is a sled on to which the application unit is attached and which over the Bottom of the tube slides.
  • a drive unit provided, which moves the movement unit through the tube.
  • the device according to the invention also has a control unit for monitoring and controlling the movement of the drive unit and / or the application of the coating material or Decoating material on the inner tube wall.
  • the stripping can be carried out by means of such a device or coating can be controlled.
  • the Share those for coating and stripping in the entrance mentioned pipes are inserted and introduced, in particular the application unit and movement unit, dimensioned according to the pipe diameter.
  • the Drive unit on a winch which over a rope Movement unit transported through the pipe. That way it is possible to combine the movement unit and application unit in one to move the inclined pipe, which, for example, down the slope has been relocated.
  • pipes are strongly inclined Course in hydropower plants available because the water to For electricity generation purposes, a slope is conducted.
  • the cable winch is then, for example, outside the pipes for example in the upper pool.

  • it is about chassis consisting of several wheels or around one Chassis that is similar to that on tracked vehicles is appropriate.
  • this Chassis on multiple wheels on multiple sides of the Movement unit are arranged. These are, for example, on all vertices of an isosceles triangle appropriate. Thanks to the wheels on several sides the movement unit can be moved lying on all these sides. Should the movement unit tip over, it comes again to lie on wheels with which it can be moved. Advantageous has the movement unit around such wheels that it at any position ultimately comes to rest on wheels with which it remains movable.
  • the wheels are therefore not only on the “bottom” of the Unit of motion but also above, for example Moving unit. This is intended to cause the Device can be moved even if this in Pipe turns upside down.
  • Chassis has multiple wheels and this such a fall have that the wheel axis each parallel to a respective Tangent of the inner pipe wall at the point of contact of the respective one Wheel runs on the inner tube wall. Fall describes the Angle of the wheels to the vertical axis of the movement unit. By the chosen camber, the wheels are perpendicular to the Inner pipe wall. This way the treads and bearings are evenly and properly loaded.
  • At least two wheels have a toe-in or toe-out, so too achieve that the path to be observed by the movement unit is stabilized.
  • the track describes the angle of the wheels Longitudinal axis of the movement unit. So you basically look at that Movement unit from above and describes how the wheels to imaginary direction of travel.
  • the wheels are in Driving direction seen closer together at the front than at the rear this is "toe-in”.
  • follow-up is therefore that the wheels are behind stand closer together than in front.
  • the toe-in causes the wheels lying in the direction of travel to to run towards each other and thus the movement in this direction is stabilized, the toe has a corresponding effect in the reverse direction.
  • the drive unit as a motorization on the movement unit appropriate.
