Description
Maschinenfundament, insbesondere für eine Turbogeneratorgruppe oder dergleichen Die Erfindung betrifft ein Maschinenfundament, insbesondere für eine Turbogeneratorgruppe, eine Gebläsegruppe oder dergleichen, bei welchem eine Maschinenfundamentplatte auf einzelnen Federele menten ruht.
Die modernen Turbogenerator- und Gebläsegrup- pen erfordern viel freien Raum unter der Maschinen fundamentplatte, um darin eine grosse Anzahl von Leitungen und Hilfsapparaturen unterbringen zu kön nen. Es ist deshalb notwendig, die Stützen der Funda mente möglichst schlank auszubilden und diese Stüt zen in grossen gegenseitigen Abständen anzuordnen. Eine solche Ausbildung des Fundamentes für die Maschinenanlage lässt sich besonders günstig aus führen, wenn zwischen der eigentlichen Maschinen fundamentplatte und den Stützen Federelemente ein gebaut werden.
Eine solche Konstruktion hat auch den Vorteil, dass dabei die schwingungstechnischen Anforderungen an die Fundamentkonstruktion ein wandfrei erfüllt werden können.
Die bekannte Ausführung hat aber den Nachteil, dass entweder die Federelemente schon vor dem Betonieren der Maschinenfundamentplatte eingebaut werden müssen, wobei zum Herausnehmen der Scha- lungselemente die Maschinenfundamentplatte durch hydraulische Pressen angehoben werden muss. Oder die Maschinenfundamentplatte muss zum Einbau der Federelemente mittels Pressen gehoben werden. Diese Arbeiten erfordern einen grossen Aufwand an Vor richtungen und Zeit.
Die Erfindung bezweckt, diese Nachteile zu ver meiden. Bei einem Maschinenfundament der eingangs geschilderten Art ist zu diesem Zweck erfindungs- gemäss für jedes Federelement eine im wesentlichen senkrechte, die Maschinenfundamentplatte durch dringende Bohrung vorgesehen, in welche eine mit der Maschinenfundamentplatte festverbundene Ge- windemutter reicht, und in die Gewindemutter ist ein sich auf das Federelement abstützender Gewinde bolzen eingeschraubt.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes vereinfacht dargestellt. Die dargestellte Maschinenfundamentplatte 1 weist eine in sie einbetonierte, d. h. mit ihr fest verbundene Gewindemutter 2 auf, in welche ein Gewindebolzen 3 eingeschraubt ist, der sich auf ein Federelement 4 abstützt. Eine im wesentlichen ,senkrechte, von der Fundamentoberfläche 5 aus die Maschinenfundamentplatte 1 durchdringende Boh rung 6, in die die Gewindemutter 2 hineinreicht, ist mittels eines Rohrstücks 7 ausgekleidet.
Das Rohrstück 7 und die Gewindemutter 2 liegen koaxial zueinander und sind miteinander verschweisst. An seinem oberen Ende trägt das Rohrstück 7 einen sich in der Maschinenfundamentplatte 1 abstützen den Gewindering B. Die Bohrung 6 dient für das Einführen eines Schlüssels 9 zum Anziehen des Gewindebolzens 3. Dieser ist dazu an seinem oberen Ende mit einem Sechskantkopf 10 versehen.
Der Gewindebolzen 3 weist eine Kugelfläche 11 auf, die in einer Pfanne 12 eines oberen Feder tellers 13 des Federelements 4 ruht. Auf einem unteren Federteller 14 liegen Tellerfedern 15 auf. Die Tellerfedern 15 sind durch einen Hals 16 des Federtellers 14 geführt. Der Hals 16 reicht in eine Bohrung 17 des oberen Federtellers 13. Die Teile des Federelements 4 sind also gegeneinander und gegenüber der Maschinenfundamentplatte 1 nur in senkrechter Richtung beweglich, sonst aber an ihrem Ort gehalten.
Das Federelement 4 ruht auf einem Fundamentgrund 18 bzw. auf einer Fundamentstütze in einem Spalt 19, der von der unter der Maschinen- fundamentplatte 1 liegenden Unterkellerung aus zu gänglich ist. Nach erfolgter Erstellung des Unterbaus 18 und der Maschinenfundamentplatte 1 werden die Feder elemente 4 in den dafür vorgesehenen Spalt 19 eingebaut.
Anschliessend werden die Gewindebolzen 3 mittels des Schlüssels 9 gegen das Federelement 4 geschraubt, bis das Gewicht der Maschinenfunda- mentplatte 1 vollständig von den Federelementen 4 aufgenommen ist. Dann kann die zum Betonieren der Maschinenfundamentplatte 1 verwendete Ver schalung entfernt werden.
Zur Fixierung der Maschinenfundamentplatte 1 während der Montage der auf ihr zu befestigenden Maschine wird der Spalt 19 durch Hartholz- oder Eisenkeile überdrückt, so dass die Maschinenfunda- mentplatte 1 gegenüber dem Fundamentgrund 18 fixiert ist.
Nach Beendigung der Montage werden die Feder elemente 4 durch gleichmässiges Anziehen aller Ge- windebolzen, 3 wieder belastet, biss die Keile gelockert sind und entfernt werden können, wonach das ge samte Gewicht der Maschinenfundamentplatte und der auf ihr liegenden Maschinenteile von den Feder elementen 4 aufgenommen wird.
Treten unterschiedliche Bodensetzungen auf, so können die Federelemente 4 ohne Betriebsunter brechungen der Anlage jederzeit durch Drehen der Gewindebolzen 3 auf die richtige Spannung nach gestellt werden. Öffnungen 20 im oberen Federteller 13 gestatten das Einführen von Messfühlern zum Messen des gegenseitigen Abstands der Federteller 13, 14, d. h. zum Messen der bestehenden Feder spannung.
Dank der Erfindung ist es auch möglich, ein zelne defekte Federelemente zu entlasten und durch neue zu ersetzen und diese wieder auf die gegebene erforderliche Belastung zu bringen ebenfalls ohne Betriebsunterbrechung der Maschinenanlage.
Machine foundation, in particular for a turbo generator group or the like. The invention relates to a machine foundation, in particular for a turbo generator group, a blower group or the like, in which a machine foundation plate rests on individual spring elements.
The modern turbo-generator and fan groups require a lot of free space under the machine foundation plate in order to be able to accommodate a large number of lines and auxiliary equipment. It is therefore necessary to make the pillars of the foundations as slim as possible and to arrange these pillars at large mutual distances. Such a formation of the foundation for the machine system can be carried out particularly favorably if spring elements are built between the actual machine foundation plate and the supports.
Such a construction also has the advantage that the vibration requirements for the foundation construction can be met without any problems.
However, the known design has the disadvantage that either the spring elements have to be installed before the machine foundation plate is concreted, with the machine foundation plate having to be lifted by hydraulic presses to remove the formwork elements. Or the machine foundation plate must be lifted using presses to install the spring elements. This work requires a great deal of equipment and time.
The invention aims to avoid these disadvantages. In the case of a machine foundation of the type described above, according to the invention for each spring element a substantially vertical, the machine foundation plate through penetrating hole is provided in which a threaded nut firmly connected to the machine foundation plate extends, and in the threaded nut is a Threaded bolt supporting the spring element.
An exemplary embodiment of the subject matter of the invention is shown in simplified form in the drawing. The machine foundation plate 1 shown has a concrete cast into it, d. H. threaded nut 2 firmly connected to it, into which a threaded bolt 3 is screwed, which is supported on a spring element 4. A substantially, vertical, from the foundation surface 5 from the machine foundation plate 1 penetrating Boh tion 6, into which the threaded nut 2 extends, is lined by means of a pipe section 7.
The pipe section 7 and the threaded nut 2 are coaxial with one another and are welded to one another. At its upper end, the pipe section 7 bears a threaded ring B supported in the machine foundation plate 1. The hole 6 is used to insert a key 9 for tightening the threaded bolt 3. This is provided with a hexagon head 10 at its upper end.
The threaded bolt 3 has a spherical surface 11 which rests in a socket 12 of an upper spring plate 13 of the spring element 4. Disk springs 15 rest on a lower spring plate 14. The disc springs 15 are guided through a neck 16 of the spring plate 14. The neck 16 extends into a bore 17 of the upper spring plate 13. The parts of the spring element 4 are therefore only movable in a vertical direction relative to one another and relative to the machine foundation plate 1, but are otherwise held in place.
The spring element 4 rests on a foundation base 18 or on a foundation support in a gap 19 which is accessible from the basement located under the machine foundation plate 1. After the substructure 18 and the machine foundation plate 1 have been created, the spring elements 4 are installed in the gap 19 provided for this purpose.
The threaded bolts 3 are then screwed against the spring element 4 by means of the key 9 until the weight of the machine foundation plate 1 is completely absorbed by the spring elements 4. Then the formwork used for concreting the machine foundation plate 1 can be removed.
To fix the machine foundation plate 1 during the assembly of the machine to be fastened to it, the gap 19 is pressed over by hardwood or iron wedges so that the machine foundation plate 1 is fixed with respect to the foundation base 18.
After assembly, the spring elements 4 are loaded again by evenly tightening all threaded bolts, 3 until the wedges are loosened and can be removed, after which the entire weight of the machine foundation plate and the machine parts lying on it are absorbed by the spring elements 4 becomes.
If different soil subsidence occurs, the spring elements 4 can be adjusted to the correct voltage at any time by turning the threaded bolt 3 without interrupting the operation of the system. Openings 20 in the upper spring plate 13 allow the insertion of measuring sensors for measuring the mutual distance of the spring plates 13, 14, i. H. to measure the existing spring tension.
Thanks to the invention, it is also possible to relieve individual defective spring elements and replace them with new ones and bring them back to the given required load, likewise without interrupting the operation of the machine system.
