Definitions

  • the invention is in the field of the storage of a horizontally lying pressure vessel and is applicable to the structural design of the displacement-free assignment of the pressure vessel and the boiler chair.
  • Support devices are known for the storage of horizontally lying, large pressure vessels, such as those used primarily in steam power plants such as conventional power plants and nuclear power plants, which essentially consist of a boiler chair arranged between the pressure vessel and the foundation with a shell-like support surface (boiler chair shell) adapted to the container wall ) consist.
  • a boiler chair arranged between the pressure vessel and the foundation with a shell-like support surface (boiler chair shell) adapted to the container wall ) consist.
  • it is known to weld holding brackets to the pressure vessel which are welded to a bearing by means of lugs, which in the installed state are on the side edge the boiler chair shell rests (DE-AS-2 840 528).
  • This functionally reliable assignment of pressure vessel and boiler chair is, however, relatively complex in terms of production technology. In addition, it does not offer any protection against twisting the pressure vessel in the boiler chair.
  • the invention has for its object to reduce the manufacturing outlay for the axial securing of the pressure vessel in the boiler chair and also to provide security against rotation.
  • the holding elements are designed as multi-layer weld fillets with a contact surface running parallel to the side edges of the boiler chair shell, a fitting piece being inserted between the respective weld fillet and the associated side edge of the boiler chair shell, which is provided by means of an on the boiler chair fixed bracket is fixed, and that to secure the container against twisting on the container shell and the boiler chair shell eyes are coaxially welded into which a non-rotatable axis is inserted.
  • Such a configuration of the fixed assignment of pressure vessel and boiler chair can be handled easily in terms of production technology and offers a secure fixation of the pressure vessel in the axial direction and in the circumferential direction.
  • the holder of the respective fitting can have the shape of a circuit board and can be welded or screwed to the boiler chair shell.
  • Figures 1 to 4 An embodiment of the new support device is shown in Figures 1 to 4.
  • Figures 1 and 2 show the support device in side view and in cross section, while Figures 3 and 4 show details of the axial fixation between the pressure vessel and the boiler chair.
  • a pressure vessel 1 lies horizontally on the boiler chair 3, which is mounted on the foundation 2.
  • the boiler chair 3 consists of the base plate 7, the support feet 4 and 5 as well as the boiler chair shell 6.
  • multi-layer welds 9 are applied to the jacket of the container, which are provided with a contact surface by appropriate mechanical processing, which is parallel to the side edge or are provided to the side surface 8 of the boiler chair shell 6.
  • Removable fitting pieces 10 are inserted between these fillet welds 9 and the kettle chair shell 6, via which the pressure vessel and the kettle chair shell are non-positively connected to one another.
  • the respective fitting piece 10 is fixed in its position by means of a circuit board 11 welded onto the boiler chair shell 6. Fitting piece 10 and board 11 are assigned to one another in such a way that the board 11 engages in a recess in the fitting piece or is pressed against the fitting piece.
  • eyes 12 are further welded to the jacket of the pressure vessel.
  • Further eyes 13 are welded to the kettle chair shell 6, all eyes being arranged coaxially.
  • a shaft 14 is inserted through the eyes, which cannot be rotated by welding with the eyes or as a result of a corresponding profiling or with the aid of feather keys in the eyes.
