Description
Tragkonsole fii'r BehälterCarrying bracket for containers
Die Erfindung betrifft Tragkonsolen für Behälter die insbesondere in Kernkraftwerken zum Einsatz kommen, wobei die Behälter aus geschmiedeten Ringen (Schüssen), Böden und Rohrplatten zusammengeschweißt sind.The invention relates to support brackets for containers in particular are used in nuclear power plants, the containers made of forged rings (Shots), floors and tube plates are welded together.
Derartige Behälter finden beispielsweise als Reaktordruckbehälter, Dampferzeuger oder Druckhalter Verwendung.Such containers are used, for example, as reactor pressure vessels, Steam generator or pressurizer use.
Bisher werden die als Schweißkonstruktionen ausgebildeten Tragkonsolen an dem Behälter angeschweißt (DT-PS 21 01 965). Die Verbindungsnähte mit dem Behälter als auch die Schweißnähte der Tragkonsolen selbst werden aufgrund des großen Gewichtes der Behälter sehr stark beansprucht. Diese Schweißnähte werden daher im Rahmen der in regelmäßigen Zeitabständen durchzuführenden Behälterinspektionen ebenfalls einer Wiederholungsprüfung mittels Ultraschall unterzogen. Bei der Durchführung der Wiederholungsprüfungen hat es sich als nachteilig gezeigt, daß diese Stellen schwer zugänglich sind, da die Tragkonsolen teilweise von den Abstützkonstruktionen in die der Behälter eingehängt ist verdeckt werden. Weiterhin hat es sich als nachteilig gezeigt, daß durch das Anschweißen der Tragkonsolen unerwünschte Spannungen in den entsprechenden Behälterbereichen entstehen.So far, the support brackets designed as welded constructions welded to the container (DT-PS 21 01 965). The connection seams with the container as well as the weld seams of the support brackets themselves are due to the great weight the container is very heavily used. These welds are therefore in the context of Container inspections to be carried out at regular intervals are also one Repeated ultrasound testing. When performing the repeat exams it has been shown to be disadvantageous that these places are difficult to access because the support brackets are partially suspended from the support structures in which the container is located is to be covered. Furthermore, it has been shown to be disadvantageous that the Welding on the support brackets unwanted stresses in the corresponding container areas develop.
Der Erfindung liegt die Aufgabe zugrunde die Tragkonsolen derart auszubilden, daß keine Schweißnähte auftreten und trotzdem eine homogene Verbindung zwischen Behälter und Tragkonsolen entsteht.The invention is based on the object of designing the support brackets in such a way that that no welds occur and still a homogeneous connection between Container and support brackets are created.
Gelöst wird die Aufgabe dadurch, daß Tragkonsolen und Ring oder Rohrplatte aus einem Stück geschmiedet sind.The object is achieved in that support brackets and ring or tube plate are forged from one piece.
Damit erübrigt sich eine Wiederholungsprüfung und die vorgenannten Nachteile wie Unzugänglichkeit und unerwünschte Spannungen im Verbindungsbereich Behälter/Tragkonsole treten erst gar nicht auf.This means that a repeat test and the aforementioned are superfluous Disadvantages such as inaccessibility and undesirable tension in the connection area The container / support bracket does not appear at all.
In einer weiteren Ausgestaltung der erfindungsgemäßen Anordnung wird vorgeschlagen die Tragkonsolen als umlaufenden Kragen auszubilden.In a further embodiment of the arrangement according to the invention proposed to train the support brackets as a circumferential collar.
Gemäß einer bevorzugten Ausführungsform weisen Ring (Schuß) und Kragen die gleiche Höhe auf.According to a preferred embodiment, the ring (weft) and collar have the same height.
Die Herstellung des Schusses mit Kragen wird durch diese Maßnahme wesentlich erleichtert, da in diesem Falle diese beiden Elemente einen glatten Ring ohne Absätze bilden.The production of the weft with collar is made by this measure much easier, since in this case these two elements form a smooth ring form without paragraphs.
Anhand der schematischen Zeichnungen (Fig. 1- 4) wird die erfindungsgemäße Tragkonsolenausbildung beschrieben.Based on the schematic drawings (Fig. 1- 4) the invention Support bracket training described.
Es zeigen: Fig. 1 im Längsschnitt einen Reaktordruckbehälter mit Tragkonsolen.They show: FIG. 1 in longitudinal section a reactor pressure vessel with support brackets.
Fig. 2 einen Schnitt entlang der Linie A-A der Fig. 1 Fig. 3 eine andere Ausbildung der Tragkonsolen.Fig. 2 is a section along the line A-A of Fig. 1; Fig. 3 is a different training of the support brackets.
Fig. 4 eine weitere Ausbildung der Tragkonsolen.Fig. 4 shows a further embodiment of the support brackets.
Fig. 5 die Anordnung der Tragkonsolen an der Rohrplatte eines Dampferzeugers Die Fig. 1 zeigt einen Reaktordruckbehälter 1 der aus mehreren geschmiedeten Ringen (Schüssen) 2 und einem Boden 8 zusammengeschweißt ist. Die Tragkonsolen 3 bilden mit einem Ring 2 ein einstückiges Schmiedestück und sind segmentförmig am Umfang dieses Ringes angeordnet(Fig. 2). Die Einrichtung 5 zur Abstützung des Reaktordruckbehälters ist strichpunktiert angedeutet.5 shows the arrangement of the support brackets on the tube plate of a steam generator Fig. 1 shows a reactor pressure vessel 1 made of several forged rings (Shots) 2 and a bottom 8 is welded together. The support brackets 3 form with a ring 2 a one-piece forging and are segment-shaped on the circumference arranged this ring (Fig. 2). The device 5 for supporting the reactor pressure vessel is indicated by dash-dotted lines.
Eine andere Ausbildung der Tragkonsolen zeigt Fig. 3. Hier sind die Tragkonsolen als umlaufender Kragen 4 ausgebildet.Another design of the support brackets is shown in Fig. 3. Here are the Support brackets designed as a circumferential collar 4.
Nach einer weiteren vorteilhaften Ausgestaltung (Fig. 4) weist der Kragen 4 die gleiche Höhe (h) auf wie der Ring 2, so daß Kragen 4 und Ring 2 einen glatten Ring ohne Absätze bilden. Diese Ausgestaltung kann selbstverständlich auch bei der Ausbildung nach Fig. 3 zur Anwendung kommen.According to a further advantageous embodiment (FIG. 4), the Collar 4 the same height (h) as the ring 2, so that collar 4 and ring 2 one Form a smooth ring without heels. This configuration can of course also be used come in the training of Fig. 3 for use.
Die Fig. 5 zeigt den Teilschnitt durch einen Dampferzeuger 6 bei dem die Tragkonsolen 3 an die Rohrplatte 7 angeschmiedet sind.Fig. 5 shows the partial section through a steam generator 6 in the the support brackets 3 are forged onto the tube plate 7.
Mit der erfindungsgemäßen Anordnung werden Tragkonsolen für die eingangs genannten Behälter geschaffen, die ohne Schweißverbindungen auskommen und somit keine aufwendige Wiederholungsprüfung erforderlich machen.With the arrangement according to the invention, support brackets for the initially created container that do without welded connections and thus do not require a costly repeat test.
