Description

Die Erfindung betrifft eine Vorrichtung zum Zusammenbau in waagerechter Lage von Wärmetauschern von beliebiger Länge und Gewicht. Im Dampfkraftwerk werden für die verschiedensten Zwecke Wärmtauscher benötigt, die aus RohrbUndeln in einem Mantelgefäß bestehen. Das unter hüherem Druck stehende Medium fliesst in den Rohren, das unter niedrigerem Druck stehende im Gefäß. Bei den heutigen Leistungen werden die Abmessungen und insbesondere die Längen dieser Wärmetauscher immer größer. Während bisher der Einbau des Rohrbündels in den Mantel am einfachsten dadurch erfolgte, daß das Rohrbündel in senkrechter Lage von einem Kran angehoben und von oben in den Mantel abgelassen wurde, erfordert dies bei den heutigen Längen solcher Wärmetauscher bis zu 20 m, so grosse Kranhöhen, daß dies nur unter großen Schwierigkeiten durchführbar ist. Von großem Nachteil bei dem bisherigen Verfahren ist weiter die Zugebelastung in den Roh#cen, und die Biege-Verformung beim Aufrichten des Rohrbündels speziell bei langen und schweren Wärmtauschern.The invention relates to a device for assembly in the horizontal Location of heat exchangers of any length and weight. Be in the steam power plant Heat exchangers are required for a wide variety of purposes, consisting of tube bundles in one Jacketed vessel exist. The medium under higher pressure flows in the pipes, that which is under lower pressure in the vessel. With today's achievements the dimensions and in particular the lengths of these heat exchangers are getting larger. While So far, the easiest way to install the tube bundle in the jacket has been that the tube bundle is lifted in a vertical position by a crane and from above in the jacket was drained, this requires such heat exchangers with today's lengths up to 20 m, crane heights so great that this can only be carried out with great difficulty is. Another major disadvantage of the previous method is the loading in the raw # cen, and the bending deformation when erecting the tube bundle in particular with long and heavy heat exchangers.

Die erwähnten 11achteile werden erfindungsgemäß da-C) verhindert, da--Q ein durch Halterungen zuja-Mmengehaltenes L> auf einen mit aufgeschweißten Gleitkufen versehenen Schlitten aus Flachstahl liegt.The mentioned disadvantages are prevented according to the invention da-C), da - Q an L> held together by brackets, welded onto one Flat steel sled provided with skids.

Erfindungsgemäß wer-den die Gleitkufen aus einem Gleit-Kunststoff hergestellt. In Erweiterung des erfindungsgemäßen GedabKeiis' di"r'Z1 der Schlitten lösbar an den Halterungen angeschlossen, so daß nach Einbau des Rohrbüridels durch Drehung des Mantels um 1800 der entlastete Schlitten herausgezogen werden kann.According to the invention, the skids are made from a sliding plastic. As an extension of the GedabKeiis' di "r'Z1 according to the invention, the slide is detachably connected to the brackets, so that after the installation of the tubular burner, the relieved slide can be pulled out by turning the jacket by 1800.

Falls die schlechten Oberflächenverhältnisse des Mantels das Gleiten der Kufen sehr erschwereng wird erfindungsgemäß der Schlitten mit den aufgeschweißten Gleitkufen auf eine in den Mantel lösbar eingebaute Schiene gleiten.In case the poor surface conditions of the mantle prevent sliding the skids are very difficult according to the invention, the slide with the welded on Slide runners slide onto a rail detachably built into the jacket.

Die Erfindung wird an Hand der Zeichnung.eines AusfUhrungsbeispiels näher erläutert. Es stellen dar: Fig. 1 einen senkrechten Querschnitt des Wärmetauschers mit der Einbau-Vorrichtung, Fig. 2 eine Vergrößerung des unteren Teils des Schnitts nach Linie II-II der Fig. 19 Fig» 3 einen Querschnitt nach Linie III-III der Fig. 2.The invention is explained in more detail with reference to the drawing. Figure 1 is a vertical cross section of the heat exchanger with built-in device, Fig 2 is an enlargement of the lower part of the section according to line II-II of Figure 19 Figure '3 is a cross section along line III-III of Fig: it represents.... 2.

Das Rohrbündel 2 mit dem Rohrboden 3 wird durch die Halterungen 6 zusammengehalten und in den beiderseits offenen Mantel 1 eingeführt. Die Halterungen 6 liegen auf den mit aufgeschweißten Gleitkufen 5 versehenen Schlitten 4, Der Schlitten 4 ist an der vordersten Halterung durch ein Winkeleisen 7 lösbar befestigt. Die Gleitkufen 5 gleiten außerhalb des Mantels 1 auf einer Gleitschiene 8, die von einem Doppel-T-Träger 9 abgestUtzt wird.The tube bundle 2 with the tube sheet 3 is held together by the holders 6 and inserted into the jacket 1, which is open on both sides. The brackets 6 lie on the slide 4, which is provided with welded-on skids 5. The slide 4 is releasably attached to the foremost bracket by means of an angle iron 7. The skids 5 slide outside of the casing 1 on a slide rail 8 which is supported by a double T-beam 9 .

Der Schlitten 4 mitsamt dem Hohrbündel 2 wird durch einen nicht dargestellten Haken, der in das Loch 10 eingreiftg von rechts nach links in den Mantel 1 eingeschoben. Wenn der Rohrboden 3 an den Mantel 1 anschlägt, wird der gesamte Wärmeaustauscher um 180 0 gedreh-#, so daß der Schlitten 4 entlastet wird. Nun wird der Schlitten 4 mit den Gleitkufen 5 und Winkeleisen 7 von der vordersten Halterung 6 gelöst und herausgezogen. Damit dte Gleitkufen 5, die meistens aus sogenanntem Gleitkunststoff hergestellt sind, besser auf der Mantelfläche 1 gleiteng wtrd diese mit Wassei oder einer anderen SchmierflUssigkeit benetzt. Im Fall von sehr ungünstigen Oberflächenverhältnissen des Mantels, the ieEkeht gleit@A, kann man eine nicht dargestellte Schiene lösbar in den Mantel einbauen, die nach dem Einbau und der Drehung um 180 0 des Wärmaustauschers entlastet und gleichzeitig mit ausgebaut wird.The carriage 4 together with the bundle of ears 2 is pushed into the jacket 1 from right to left by means of a hook, not shown, which engages in the hole 10 . When the tube sheet 3 strikes the jacket 1 , the entire heat exchanger is rotated through 180 °, so that the carriage 4 is relieved. Now the carriage 4 with the runners 5 and angle iron 7 is released from the foremost bracket 6 and pulled out. So that the skids 5, which are mostly made of so-called sliding plastic, can slide better on the outer surface 1, this is wetted with water or another lubricating fluid. In the case of very unfavorable surface conditions of the jacket, the ieEkeht gleit @ A, you can get one that is not shown Install the rail detachably in the jacket, which is relieved and removed at the same time after installation and rotation of the heat exchanger by 180 °.
