Abstract

1. A supporting arrangement for horizontally disposed cylindrical pressure vessels, particularly for such pressure vessels in steam power plants, consisting of a boiler support located between the vessel and the base, with a dish-shaped support surface (boiler support dish), the vessel being axially fixed with respect to the boiler support by means of supporting members at one or more points, these supporting members being, on the one hand, connected to the vessel wall and, on the other hand, engaged with the boiler support, characterised in that for simultaneously securing the vessel against rotation, each supporting member consists of a bolt (7), which is guided axially, by means of a sleeve (6), into a supporting structure (5) which is detachably fastened on the boiler support (2), and is engaged radially with a recess (9) provided in the vessel wall (1) or with a socket welded onto the vessel wall (1).

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 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 Auflagefläche des Kesselstuhls anliegt (DE-AS 2 840 528). Diese von der Funktion her sichere Zuordnung von Druckbehälter und Kesselstuhl ist allerdings fertigungstechnisch 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 are 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 and having a shell-like support surface adapted to the vessel wall. 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 contact surface of the boiler chair rests (DE-AS 2 840 528). This functionally reliable assignment of pressure vessel and boiler chair is, however, 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 US-A-2 463 880 ist eine Abstützvorrichtung für waagerecht liegende, zylindrische Druckbehälter bekannt, die aus einem zwischen dem Behälter und dem Fundament angeordneten Kesselstuhl mit ringförmigen Auflageflächen besteht, wobei der Behälter gegenüber dem Kesselstuhl an mehreren Stellen mittels Halteelementen axial fixiert ist, die mit dem Behältermantel verbunden sind. Hierbei besteht das jeweilige Halteelement zur gleichzeitigen Sicherung des Behälters gegen Verdrehen aus einem auf den Behältermantel aufgeschweissten Rohrstutzen, der in eine über eine Tragkonstruktion lösbar befestigte Hülse eingreift.From US-A-2 463 880 a support device for horizontally lying, cylindrical pressure vessels is known, which consists of a kettle chair arranged between the vessel and the foundation with annular bearing surfaces, the vessel being axially fixed to the kettle chair at several points by means of holding elements which are connected to the container jacket. Here, the respective holding element for simultaneously securing the container against twisting consists of a pipe socket welded onto the container jacket, which engages in a sleeve which is detachably fastened via a supporting structure.

Ausgehend von einer Abstützvorrichtung mit den Merkmalen des ersten Teils des Patentanspruchs liegt der Erfindung die Aufgabe zugrunde, die Halteelemente und deren Verbindung mit dem Behältermantel sowie deren Eingriff mit dem Kesselstuhl so auszugestalten, dass mit geringem Aufwand an Schweissarbeiten eine Fixierung des Behälters sowohl in axialer Richtung als auch in Umfangsrichtung erzielt wird.Starting from a support device with the features of the first part of the patent claim, the invention is based on the object of designing the holding elements and their connection to the container jacket and their engagement with the boiler chair in such a way that the container can be fixed both in the axial direction with little effort in welding work as well as in the circumferential direction.

Zur Lösung dieser Aufgabe ist gemäss der Erfindung vorgesehen, dass das jeweilige Halteelement aus einem Bolzen besteht, der in einer am Kesselstuhl lösbar befestigten Tragkonstruktion mittels einer Hülse axial geführt ist und mit einer in dem Behältermantel vorgesehenen Vertiefung oder mit einem auf den Behältermantel aufgeschweissten Rohrstutzen radial im Eingriff steht.To achieve this object it is provided according to the invention that the respective holding element consists of a bolt which is axially guided in a support structure releasably attached to the boiler chair by means of a sleeve and radial with a recess provided in the container jacket or with a pipe socket welded onto the container jacket is engaged.

Ein Ausführungsbeispiel der neuen Abstützvorrichtung ist in den Figuren 1 und 2 dargestellt.An embodiment of the new support device is shown in Figures 1 and 2.

Gemäss den Figuren 1 und 2 liegt ein Druckbehälter mit dem Behältermantel 1 waagerecht auf dem Kesselstuhl 2 auf, der aus dem Fuss 3 und der schalenartigen Auflagefläche 4, nämlich der Kesselstuhlschale, besteht. Auf den Kesselstuhl ist eine Tragkonstruktion 5 für eine zylindrische Hülse 6 lösbar aufgesetzt, wobei die Hülse 6 radial zum Behälter angeordnet ist. In der Hülse 6 ist ein Bolzen 7 geführt und mit einem Querstift 8 fixierbar. Der Bolzen 7 ragt in eine Ausnehmung 9 der Behälterwand 1 ein. Wenn die Behälterwand sehr dünn ist «, 35 mm), kann man auf diese einen Rohrstutzen aufschweissen, in den dann der Bolzen 7 eingesteckt wird.According to FIGS. 1 and 2, a pressure container with the container jacket 1 lies horizontally on the boiler chair 2, which consists of the foot 3 and the shell-like support surface 4, namely the boiler chair shell. A support structure 5 for a cylindrical sleeve 6 is detachably placed on the boiler chair, the sleeve 6 being arranged radially to the container. A bolt 7 is guided in the sleeve 6 and can be fixed with a cross pin 8. The bolt 7 protrudes into a recess 9 in the container wall 1. If the container wall is very thin, 35 mm), a pipe socket can be welded onto it, into which the bolt 7 is then inserted.
