Description

Vorrichtung zurn Abstützen des Laufrades., in den verhältnismäßig en-en Schächten von W4S.sertürbinen Im modernen Großturbinenbau wird oft die Forderung gestellt, den Turbinenläufer, gegebenenfalls samt zugehöriger Welle und Aufbau, im Turbinenschacht abzustützen. Zu diesem Zwecke werden für gewöhnlich waagerechte Trägerroste verwendet. Bei größeren Abmessungen der Maschine bringt jedoch die Verwendung solcher Roste Schwierigkeiten mit sich, weil sie einmal nicht leicht anzubringen sind und sodann, weil deren Aufbewahrung zur Zeit ihrer Nichtverwendung Schwierigkeit-en bereitet. Außerdem sind für die Abstützträger groß#e Profile zu verwenden, was einen mengenmäßig großen Aufwand an Profilstahl bedingt.Device for supporting the impeller., In the relatively en-en shafts of W4S.sertürbinen In modern large turbine construction, the requirement is often provided, the turbine rotor, possibly including the associated shaft and structure, to be supported in the turbine shaft. For this purpose, horizontal ones are usually used Support grids used. With larger dimensions of the machine, however, brings the use such grates cause difficulties because they are not easy to install and then because their retention is difficult at the time of their non-use prepares. In addition, large profiles are to be used for the support beams, which is a large amount of profile steel required.

Zweck vorliegender Erfindung ist, ei-ne Vorrichtung. zum Abstützen schwerer Lasten in verhältnismäßig engen Schächten von Wasserturbinen zu schaffen, bei der die vorstehend erwähnten Mängel behoben sind. Insbesondere bezweckt die Erfindung eine nur vorübergehend beim Ein- und Ausbau des Laufrades anzubringende, während des Betriebes dagegen nicht vorhandene Vorrichtung der erwähnten Art zum Abstützen der Laufräder von Wasserturbinen zu schaffen, welche drei oder mehrere Stützen aufweist, die abnehmbar an einer gemeinsamen Platte angebracht sind und in deren Betriebslage nach Art eines Sprengwerkes die Last auf die Schachtwandung übertragen.The purpose of the present invention is to provide a device. to support to create heavy loads in relatively narrow shafts of water turbines, in which the above-mentioned deficiencies have been remedied. In particular, the Invention of a temporary installation and removal of the impeller, during operation, on the other hand, there is no device of the type mentioned for Supporting the impellers of water turbines to create which three or more Has supports which are removably attached to a common plate and in their operating position in the manner of a truss structure, the load on the shaft wall transfer.

Auf der Zeichnung ist beispielsweise eine Ausführungsform einer Abstützvorrichtung gemäß der Erfindung veranschaulicht. In der Figur bezeichnet i eine Platte mit Lappen 2. 3 sind Stützarme, die mit Augen 4 versehen sind. 5 bezeichnet Bolzen, die sich durch die Lappen 2 und Augen 4 steckenlassen, so daß sie eine lösbare Verbindung zwischen den Armen 3 und der Platte i herzustellen gestatten. Die Arme 3 sind gleichzeitig schwenkbar um die Bolzen 5. Das von der Platte i ueg gelegene Ende 6 der Arme 3 ist wink-elförmig ausgebildet, so daß es sich auf einen entsprechend geformten Absatz der Schachtwandung 7 aufsetzen läßt.In the drawing, for example, an embodiment of a support device according to the invention is illustrated. In the figure, i denotes a plate with tabs 2. 3 are support arms which are provided with eyes 4. 5 denotes bolts which can be stuck through the tabs 2 and eyes 4, so that they allow a detachable connection to be made between the arms 3 and the plate i. The arms 3 are at the same time pivotable about the bolts 5. The end 6 of the arms 3 located on the plate i ueg is angular so that it can be placed on a correspondingly shaped shoulder of the shaft wall 7.

Ist die Vorrichtung beispielsweise zum Ab- stützen des Laufrades 8 einer Kaplanturbine zu verwenden, so werden die Arme3 in den Schacht eingeführt und mit der Platte i verbunden, um dann in der in der Figur ge- zeigten Weise nach Art eines Sprengwerkes ausgebreitet zu werden, wobei deren Enden6 zum Aufliegen auf die Schachtwandung 7 kommen. Die Last des Laufrades 8 wird nun von dieser Abstützvorrichtung auf die Schachtwandung 7 übertragen. Sobald die Abstützung nicht mehr benötigt wird, werden die Arme 3 von der Platte i gelöst, um hierauf unter möglichst geringer Inanspruchnahme von Raum an einer geeigneten Stelle aufbewahrt oder im zerlegten Zustande nach einer neuen Verwendungsstelle gebracht zu werden. An letzterer können sie wieder in der vorstehend beschriebenen Weise zusammengebaut und aufgestellt werden. Bei Kraftwerken mit mehreren Wasserturbinen braucht es somit eine einzige Abstützvorrichtung der beschriebenen Art. Die neue Abstützvorrichtung weist zudem den Vorteil auf, daß sich bei deren Herstellung mit einem Mindestaufwand an Baustoff auskommen läßt.If the device, for example, for disconnecting support of the impeller 8 of a Kaplan turbine to use, the Arme3 be introduced into the shaft and connected to i with the plate overall and then in the in the figure shown the manner of a snap plant to be propagated, the ends 6 of which come to rest on the shaft wall 7 . The load of the impeller 8 is now transferred to the shaft wall 7 by this support device. As soon as the support is no longer required, the arms 3 are detached from the plate i in order to be stored in a suitable place with the least possible use of space or to be taken to a new place of use in the disassembled state. On the latter, they can be reassembled and set up in the manner described above. In power plants with several water turbines, a single support device of the type described is required. The new support device also has the advantage that it can be manufactured with a minimum of building material.
