Abstract
Description
Die Erfindung liegt auf dem Gebiet der Lagerung eines waagerecht liegenden Druckbehälters und ist bei der konstruktiven Ausgestaltung der verschiebungsfreien Zuordnung von Druckbehälter und Kesselstuhl anzuwenden.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.
Zur Lagerung waagerecht liegender, grosser Druckbehälter, wie sie vor allem in Dampfkraftanlagen wie konventionellen Kraftwerken und Kernkraftwerken eingesetzt werden, sind Abstützvorrichtungen bekannt, die im wesentlichen aus einem zwischen dem Druckbehälter und dem Fundament angeordneten Kesselstuhl mit einer an die Behälterwand angepassten, schalenartigen Auflagefläche (Kesselstuhlschale) bestehen. Um axiale Verschiebungen zwischen dem Druckbehälter und dem Kesselstuhl, wie sie beispielsweise durch Stossbeanspruchungen (z.B. Erdbeben) auftreten könnten, zu vermeiden, ist es bekannt, an den Druckbehälter Halteeisen anzuschweissen, die über Knaggen mit einem Lager verschweisst sind, das im Einbauzustand an der Seitenkante der Kesselstuhlschale anliegt (DE-AS-2 840 528). Diese von der Funktion her sichere Zuordnung von Druckbehälter und Kesselstuhl ist allerdings fertigungstechnisch relativ aufwendig. Sie bietet ausserdem keine Sicherung gegen Verdrehen des Druckbehälters im Kesselstuhl.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. In order to avoid axial displacements between the pressure vessel and the boiler chair, as might occur, for example, due to impact loads (e.g. earthquakes), 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.
Aus der FR-A-2 168 674 ist es zur Sicherung eines kugelförmigen Behälters gegen Verdrehen bekannt, seitlich am Behältermantel und an der Kesselstuhlschale Augen aufzuschweissen und jeweils einen Bolzen nicht verdrehbar einzustecken.From FR-A-2 168 674 it is known, in order to secure a spherical container against twisting, to weld eyes to the side of the container shell and to the kettle chair shell and to insert a bolt each so that it cannot rotate.
Ausgehend von einer Abstützvorrichtung mit den Merkmalen des ersten Teils des Anspruches 1 liegt der Erfindung die Aufgabe zugrunde, den fertigungstechnischen Aufwand für die axiale Sicherung des Druckbehälters im Kesselstuhl zu verringern und darüber hinaus eine Sicherung gegen Verdrehen vorzusehen.Starting from a support device with the features of the first part of claim 1, 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.
Zur Lösung dieser Aufgabe ist gemäss der Erfindung vorgesehen, dass die Halteelemente als mehrlagige Auftragsschweissungen mit einer parallel zu den Seitenkanten der Kesselstuhlschale verlaufenden Anlageflächen ausgebildet sind, wobei zwischen die jeweilige Auftragsschweissung und die zugeordnete Seitenkante der Kesselstuhlschale ein Passstück eingefügt ist, das mittels einer am Kesselstuhl befestigten Halterung fixiert ist, und dass zur Sicherung des Behälters gegen Verdrehen auf dem Behältermantel und die Kesselstuhlschale Augen koaxial aufgeschweisst sind, in die eine nicht verdrehbare Achse eingesteckt ist.To achieve this object, it is provided according to the invention that 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.
Eine derartige Ausgestaltung der fixierten Zuordnung von Druckbehälter und Kesselstuhl lässt sich fertigungstechnisch einfach handhaben und bietet eine sichere Fixierung des Druckbehälters in axialer Richtung sowie in Umfangsrichtung. Dabei kann die Halterung des jeweiligen Passstückes die Form einer Platine haben und mit der Kesselstuhlschale verschweisst oder verschraubt sein.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.
Ein Ausführungsbeispiel der neuen Abstützvorrichtung ist in den Figuren 1 bis 4 dargestellt. Dabei zeigen die Figuren 1 und 2 die Abstützvorrichtung in Seitenansicht sowie im Querschnitt, während die Figuren 3 und 4 Details der axialen Fixierung zwischen Druckbehälter und Kesselstuhl wiedergegeben.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.
Gemäss Fig. 1 liegt ein Druckbehälter 1 waagerecht auf dem Kesselstuhl 3 auf, der auf das Fundament 2 montiert ist. Der Kesselstuhl 3 besteht aus der Grundplatte 7, den Tragfüssen 4 und 5 sowie der Kesselstuhlschale 6. Seitlich der Kesselstuhlschale sind auf den Mantel des Behälters 1 mehrlagige Auftragsschweissungen 9 aufgebracht, die durch entsprechende mechanische Bearbeitung mit einer Anlagefläche versehen sind, die parallel zur Seitenkante bzw. zur Seitenfläche 8 der Kesselstuhlschale 6 versehen sind. Zwischen diese Auftragsschweissungen 9 und die Kesselstuhlschale 6 sind herausnehmbare Passstücke 10 eingefügt, über die der Druckbehälter und die Kesselstuhlschale kraftschlüssig miteinander verbunden sind. Gemäss den Figuren 3 und 4 ist das jeweilige Passstück 10 mittels einer auf die Kesselstuhlschale 6 geschweissten Platine 11 in seiner Lage fixiert. Passstück 10 und Platine 11 sind einander so zugeordnet, dass die Platine 11 in eine Ausnehmung des Passstückes eingreift oder gegen das Passstück gedrückt ist.1, a pressure vessel 1 lies horizontally on the boiler chair 3, which is mounted on the
Zur Sicherung des Druckbehälters 1 gegen Verdrehen sind weiterhin mit dem Mantel des Druckbehälters Augen 12 verschweisst. Weitere Augen 13 sind mit der Kesselstuhlschale 6 verschweisst, wobei alle Augen koaxial angeordnet sind. Durch die Augen ist eine Welle 14 gesteckt, die durch Verschweissung mit den Augen oder infolge einer entsprechenden Profilierung oder mit Hilfe von Passfedern in den Augen nicht verdrehbar ist.To secure the pressure vessel 1 against
