Description

Die Erfindung betrifft ein Verfahren zur Montage und/oder Demontage von Komponenten einer ein Turbinengehäuse aufweisenden Turbine. Darüber hinaus betrifft die Erfindung einen Adapter und ein System zur Verwendung in diesem Verfahren. Schließlich betrifft die Erfindung die Verwendung eines Adapters.The invention relates to a method for assembling and / or disassembling components of a turbine having a turbine housing. The invention also relates to an adapter and a system for use in this method. Finally, the invention relates to the use of an adapter.

Im Rahmen der Montage und/oder Demontage von Turbinenkomponenten, bei denen es sich beispielsweise um die Schaufeln der Turbine handeln kann, besteht die Problematik, dass die Bauteile mitunter ein nicht unbeachtliches Gewicht haben und in einer ungünstigen Arbeitsposition montiert beziehungsweise demontiert werden müssen. Bei einigen Turbinentypen ist es beispielsweise erforderlich, dass die Demontage der Laufschaufeln in 12-Uhr-Position des Läufers erfolgt. Das Gewicht der Laufschaufeln liegt dabei mitunter im Bereich von über 40, beispielsweise zwischen 46 und 48 kg.In the context of the assembly and / or disassembly of turbine components, which can be the blades of the turbine, for example, there is the problem that the components sometimes have a not inconsiderable weight and have to be assembled or disassembled in an unfavorable working position. In the case of some types of turbines, for example, it is necessary for the blades to be dismantled with the rotor in the 12 o'clock position. The weight of the rotor blades is sometimes in the range of over 40, for example between 46 and 48 kg.

Eine händische Montage bzw. Demontage ist aufgrund des Gewichtes und der ungünstigen Arbeitsposition problematisch. Ein Monteur müsste bei 12-Uhr-Position des Läufers in das Austrittsgehäuse klettern, dort die Laufschaufeln händisch demontieren und anschließend einem Kollegen übergeben, damit dieser die Schaufeln abtransportieren kann.A manual assembly or disassembly is problematic due to the weight and the unfavorable working position. A fitter would have to climb into the outlet casing when the rotor is in the 12 o'clock position, manually dismantle the blades and then hand them over to a colleague so that he can transport the blades away.

Die EP 2 535 530 A2 offenbart ein System und ein Verfahren zur Montage von Komponenten einer Turbine, bei welchem ein Kran an dem Turbinengehäuse befestigt wird, und wenigstens ein Element eines Triebwerksgehäuses mit Hilfe des Krans in seine Einbauposition gebracht wird. Der Kran weist einen Turm und einen fest mit diesem verbundenen Ausleger auf.The EP 2 535 530 A2 discloses a system and a method for assembling components of a turbine, in which a crane is attached to the turbine housing, and at least one element of an engine housing is brought into its installation position with the aid of the crane. The crane has a tower and a boom permanently connected to it.

Die EP 3 023 606 A1 betrifft ein Kransystem für eine Gasturbine, welche an ihrem Außengehäuse ein Mannloch mit einem Befestigungsabschnitt aufweist. Das Kransystem umfasst einen Kran mit einer Säule und einem gelenkig mit dieser verbundenen Auslegerarm. Der Kran ist über einen am Ende der Säule vorgesehenen Gegenbefestigungsabschnitt mittels einer Flanschverbindung mit dem Befestigungsabschnitt verbunden.The EP 3 023 606 A1 relates to a crane system for a gas turbine which has a manhole with a fastening section on its outer housing. The crane system comprises a crane with a column and a boom arm articulated therewith. The crane is connected to the fastening section by means of a flange connection via a counter-fastening section provided at the end of the column.

Die EP 2 543 868 A2 offenbart eine Wartungsvorrichtung für eine Turbine, um wenigstens eine zu demontierende Komponente der Turbine aus ihrer Einbauposition zu entfernen. Die Wartungsvorrichtung umfasst eine Hebevorrichtung, mit einem Träger, dessen eines Ende mit einem zylinderförmigen Befestigungsbolzen an der oberen Region des Außenflansches der Turbine befestigt ist und dessen anderes Ende von zwei in ihrer Länge verstellbaren Stützen gestützt wird.The EP 2 543 868 A2 discloses a maintenance device for a turbine in order to remove at least one component of the turbine which is to be dismantled from its installation position. The maintenance device comprises a lifting device with a beam, one end of which is fastened to the upper region of the outer flange of the turbine with a cylindrical fastening bolt and the other end of which is supported by two adjustable supports.

Schließlich zeigt die EP 2 900 615 A1 eine Vorrichtung zum Einbauen und Ausbauen eines Bauteils einer Turbine umfassend ein Schienensystem, auf welchem wenigstens ein Läufer vorgesehen ist, der entlang einer vorbestimmten Verschiebachse verschoben werden kann. Auf dem Läufer ist ein verstellbarer Lastarm befestigt, der zur Bildung einer lösbaren Verbindung mit dem betreffenden Bauteil ausgebildet ist.Finally shows the EP 2 900 615 A1 a device for installing and removing a component of a turbine comprising a rail system on which at least one runner is provided, which can be displaced along a predetermined displacement axis. An adjustable load arm, which is designed to form a detachable connection with the relevant component, is attached to the rotor.

Ausgehend hiervon besteht die Aufgabe der vorliegenden Erfindung darin, eine einfache und sichere Montage und/oder Demontage von Komponenten von Turbinen zu ermöglichen.Based on this, the object of the present invention is to enable simple and secure assembly and / or disassembly of turbine components.

Diese Aufgabe wird gelöst durch ein Verfahren gemäß Anspruch 1.This object is achieved by a method according to claim 1.

Der Grundgedanke der vorliegenden Erfindung besteht mit anderen Worten darin, einen Kran an einem Turbinengehäuse direkt oder indirekt, dann bevorzugt über einen Adapter, zu befestigen und unterstützt durch den Kran Turbinenkomponenten für deren Montage beziehungsweise Demontage zu einer Einbauposition an der Turbine zu transportieren beziehungsweise aus einer solchen abzutransportieren.In other words, the basic idea of the present invention is to attach a crane to a turbine housing directly or indirectly, then preferably via an adapter, and to transport turbine components for their assembly or disassembly to an installation position on the turbine or from a supported by the crane to transport such away.

Die erfindungsgemäße Befestigung des Krans an dem Turbinengehäuse bietet dabei zum einen den Vorteil, dass der Kran besonders nah an der Montage- bzw. Demontageposition angeordnet werden kann. Darüber hinaus kann auf schwere Gegengewichte am Fuße des Krans verzichtet werden, da die Turbine selber das erforderliche Gegengewicht darstellt, welches auch für den Transport vergleichsweise schwerer Komponenten ausreicht.Fastening the crane to the turbine housing according to the invention offers the advantage that the crane can be arranged particularly close to the assembly or disassembly position. In addition, heavy counterweights at the foot of the crane can be dispensed with, since the turbine itself is the required counterweight, which is also sufficient for the transport of comparatively heavy components.

Bei dem erfindungsgemäß zum Einsatz kommenden Kran handelt es sich bevorzugt um einen mobilen Kran, der sich u.a. aufgrund seiner Abmessungen und seines Gewichtes mit geringem Aufwand bei Bedarf an einen erforderlichen Einsatzort an einer Turbine transportieren lässt.The crane used according to the invention is preferably a mobile crane which, due to its dimensions and weight, among other things, can be transported with little effort to a required location on a turbine if required.

Bei dem Kran handelt es sich um einen solchen, der einen Turm und einen gelenkig an dem Turm befestigten Ausleger aufweist, was sich als besonders geeignet erwiesen hat. Kommt dieser Krantyp zum Einsatz, wird bevorzugt das freie Ende des Turms an dem Turbinengehäuse befestigt. Mit dem Ausleger des Krans können dann flexibel unterschiedliche Einbaupositionen von Turbinenkomponenten erreicht werden. Die Höhe des Turms ist zweckmäßiger Weise derart gewählt, dass der Ausleger den Rotor der Turbine übergreifen kann.The crane is one which has a tower and a boom attached to the tower in an articulated manner, which has proven to be particularly suitable. If this type of crane is used, the free end of the tower is preferably attached to the turbine housing. With the boom of the crane, different installation positions of turbine components can then be reached flexibly. The height of the tower is expediently chosen so that the boom can reach over the rotor of the turbine.

Der Kran wird insbesondere im geöffneten Zustand eines Turbinengehäuses, welches durch eine bevorzugt zumindest im Wesentlichen horizontal verlaufende Teilfuge zweigeteilt ist, an der unteren Gehäusehälfte im Bereich der Teilfuge befestigt.The crane is fastened to the lower housing half in the area of the parting line, in particular in the open state of a turbine housing, which is divided into two parts by a parting joint that preferably runs at least substantially horizontally.

Bei dem erfindungsgemäßen Verfahren wird der Kran unter Verwendung wenigstens einer in dem Turbinengehäuse, insbesondere in der unteren Gehäusehälfte im Bereich der Teilfuge vorhandenen Durchgangsbohrung an dem Turbinengehäuse befestigt. Werden eine oder mehrere ohnehin in dem Gehäuse vorhandene Bohrungen verwendet, ist eine Anpassung des Gehäuses für die Durchführung des erfindungsgemäßen Verfahrens nicht erforderlich und der Aufwand somit besonders gering. Insbesondere können diejenigen Durchgangsbohrungen für die Befestigung des Krans herangezogen werden, durch welche sich im geschlossenen Zustand des Gehäuses die Teilfugenbolzen für den Gehäuseverschluss erstrecken.In the method according to the invention, the crane is fastened to the turbine housing using at least one through-hole that is present in the turbine housing, in particular in the lower housing half in the area of the parting line.

Hierzu wurde in einem ersten Schritt ein mobiler Kran 5 an dem Turbinengehäuse befestigt. Die Figur 1 zeigt den Kran 5 in dem bereits an dem Gehäuse befestigten Zustand.For this purpose, a mobile crane 5 was attached to the turbine housing in a first step. The Figure 1 shows the crane 5 in the state already attached to the housing.

Der mobile Kran 5 umfasst einen Turm 6 und einen gelenkig an dem Turm befestigten Ausleger 7. Der Ausleger 7 ist für eine größere Flexibilität hinsichtlich der Auslenkung in drei Segmente 8 unterteilt, die wiederum gelenkig miteinander verbunden sind. Am freien Ende des Auslegers 7 ist ein Seil 9 befestigt, dessen anderes Ende mit einer Aufnahme für eine Turbinenschaufel 4 verbunden ist, die vorliegend durch einen in den Figuren nur schematisch angedeuteten Greifer gegeben ist, bei dem es sich vorliegend um einen C-Haken handelt.The mobile crane 5 comprises a tower 6 and an articulated boom 7 attached to the tower.

Im Rahmen des dargestellten Ausführungsbeispiels des erfindungsgemäßen Verfahrens ist der Kran 5, konkret das in der Figur 1 nach unten weisende freie Ende des Turms 6 des Krans 5 an der unteren Gehäusehälfte 3 im Bereich der horizontal verlaufenden Teilfuge 11 des Turbinengehäuses befestigt worden.In the context of the illustrated embodiment of the method according to the invention, the crane 5, specifically that in FIG Figure 1 downwardly facing free end of the tower 6 of the crane 5 has been attached to the lower housing half 3 in the area of the horizontally extending parting line 11 of the turbine housing.

Der Turm 6 des Krans 5 ist dabei nicht direkt mit der unteren Gehäusehälfte 3 verbunden, sondern über einen erfindungsgemäßen Adapter 12.The tower 6 of the crane 5 is not connected directly to the lower housing half 3, but via an adapter 12 according to the invention.

Eine vergrößerte Darstellung des den Turm 6 des Krans 5 mit der unteren Gehäusehälfte 3 der Turbine 1 verbindenden Adapters 12 kann der Figur 2 entnommen werden. Weitere vergrößerte Darstellungen in unterschiedlichen Ansichten sowie Schnittdarstellungen des Adapters 12 gehen aus den Figuren 4 bis 9 hervor.An enlarged view of the adapter 12 connecting the tower 6 of the crane 5 to the lower housing half 3 of the turbine 1 can be seen in FIG Figure 2 can be removed. Further enlarged representations in different views and sectional representations of the adapter 12 can be found in FIGS Figures 4 to 9 emerged.

Der Adapter 12 weist eine bei seiner Montage dem Kran 5 zuzuwendenden kranseitige Anschlagfläche 13 und eine bei seiner Montage der unteren Gehäusehälfte 3 der Turbine 1 zuzuwendende gehäuseseitige Anschlagfläche 14. Konkret umfasst der Adapter 12 eine die kranseitige Anschlagfläche 13 definierende kranseitigen Grundplatte 15 und eine die gehäuseseitige Anschlagfläche 14 definierende gehäuseseitige Grundplatte 16. Die kranseitige Grundplatte 15 zeichnet sich durch eine quadratische und die gehäuseseitige Grundplatte 16 durch eine runde Form aus. Die gehäuseseitige Grundplatte 16 wird bei dem dargestellten Ausführungsbeispiel durch zwei aufeinanderliegende Teilplatten gebildet, die, wie aus den Figuren 6 und 8 hervorgeht, mittels Schrauben 23 miteinander verbunden sind.The adapter 12 has a crane-side stop surface 13 that faces the crane 5 during its assembly and a housing-side stop surface 14 that faces the lower housing half 3 of the turbine 1 during its assembly Housing-side base plate 16 defining stop surface 14. Crane-side base plate 15 is characterized by a square shape and housing-side base plate 16 by a round shape. The housing-side base plate 16 is at the illustrated embodiment formed by two superposed partial plates, which, as from the Figures 6 and 8th shown, are connected to one another by means of screws 23.

In der runden gehäuseseitigen Grundplatte 16 sind zwei Ausnehmungen 17 vorgesehen, die sich bis zum Rand der Grundplatte 16 erstrecken. Über diese wird Platz für nicht entfernbare Elemente geschaffen, die an der unteren Gehäusehälfte 3 im Bereich der Teilfuge 11 vorhanden sein können bzw. sind. Beispielsweise können Köpfe von montierten Schrauben bzw. die freien Enden von montierten Gewindestangen und/oder Muttern vorhanden sein, die aus Stabilitätsgründen nicht demontiert werden dürfen.In the round base plate 16 on the housing side, two recesses 17 are provided which extend to the edge of the base plate 16. This creates space for non-removable elements that can or are present on the lower housing half 3 in the area of the parting line 11. For example, there may be heads of mounted screws or the free ends of mounted threaded rods and / or nuts, which for reasons of stability may not be dismantled.

Die beiden Grundplatten 15, 16 sind über ein rohrförmiges Verbindungselement 18, an dessen einer Stirnseite die gehäuseseitige Grundplatte 16 und an dessen anderer Stirnseite die kranseitigen Grundplatte 15 befestigt ist, und über vier Stabilisierungsstege 19, die entlang den Diagonalen durch die viereckige kranseitige Grundplatte 15 orientiert sind, miteinander verbunden. Das rohrförmige Verbindungselement 18 zeichnet sich, wie in der Figur 4 erkennbar, durch einen quadratischen Querschnitt aus.The two base plates 15, 16 are connected via a tubular connecting element 18, on one end of which the housing-side base plate 16 is attached and on the other end of which the crane-side base plate 15 is attached, and via four stabilizing webs 19, which are oriented along the diagonals through the square crane-side base plate 15 are connected to each other. The tubular connecting element 18 is distinguished, as in FIG Figure 4 recognizable by a square cross-section.

Die beiden Grundplatten 15, 16 erstrecken sich ferner zumindest im Wesentlichen parallel zueinander.The two base plates 15, 16 also extend at least substantially parallel to one another.

Damit der Kran 5 über den Adapter 12 an der unteren Gehäusehälfte 3 der Turbine 1 befestigt werden kann, weist der Adapter 12 einerseits Mittel zur Befestigung an der unteren Gehäusehälfte 3 auf, die vorliegend einen von der gehäuseseitigen Grundplatte 16 abragenden zylinderförmigen Befestigungsbolzen 20 umfassen, sowie andererseits Mittel zur Befestigung an dem Kran 5, die vorliegend vier in der kranseitigen Grundplatte 15 vorgesehene Gewindebohrungen 21 umfassen.So that the crane 5 can be fastened to the lower housing half 3 of the turbine 1 via the adapter 12, the adapter 12 has, on the one hand, means for fastening to the lower housing half 3, which in the present case comprise a cylindrical fastening bolt 20 protruding from the housing-side base plate 16, and also on the other hand, means for fastening to the crane 5, which in the present case comprise four threaded bores 21 provided in the base plate 15 on the crane side.

Die vier Gewindebohrungen 21 sind, wie ebenfalls der Figur 4 entnehmbar, in den vier Ecken der kranseitigen Grundplatte 15 angeordnet. Ihr Bohrbild korrespondiert zu demjenigen von vier Durchgangsbohrungen, die an dem Turm 6 des Krans 5, konkret in einer an dem freien Ende des Turms 6 vorgesehenen Fußplatte des Krans 5 vorgesehen sind (vgl. Figur 2). Die Mittel des Adapters 12 zur Befestigung an dem Kran 5 umfassen weiterhin vier Schrauben 23, die sich jeweils durch eine Durchgangsbohrung in der Fußplatte erstrecken und in eine korrespondierende Gewindebohrung 21 in der kranseitigen Grundplatte 15 eingeschraubt sind. Auf diese Weise ist der Adapter 12 mit dem Turm 6 des Krans 5 stabil lösbar verbunden.The four threaded holes 21 are, like also the Figure 4 removable, arranged in the four corners of the base plate 15 on the crane side. Your drilling pattern corresponds to that of four through-holes which are provided on the tower 6 of the crane 5, specifically in a base plate of the crane 5 provided at the free end of the tower 6 (cf. Figure 2 ). The means of the adapter 12 for fastening to the crane 5 furthermore comprise four screws 23, which each extend through a through hole in the base plate and are screwed into a corresponding threaded hole 21 in the crane-side base plate 15. In this way the adapter 12 is connected to the tower 6 of the crane 5 in a stable releasable manner.

Die Befestigung des Adapters 12 an der unteren Gehäusehälfte 3 wird bei dem dargestellten Ausführungsbeispiel über den insbesondere Figur 4 entnehmbaren zylinderförmigen Befestigungsbolzen 20 erzielt, welcher von der gehäuseseitigen Grundplatte 16, konkret von derjenigen Seite dieser, welche die gehäuseseitige Anschlagfläche 14 definiert, abragt. Die Außenkontur des Befestigungsbolzens 20 ist an die Innenkontur einer in der unteren Gehäusehälfte 3 im Bereich der Teilfuge 11 vorhandenen Durchgangsbohrung angepasst, durch welche sich im geschlossenen Zustand des Turbinengehäuses die Teilfugenbolzen zur Verbindung der beiden Gehäusehälften erstrecken.The attachment of the adapter 12 to the lower housing half 3 is in the illustrated embodiment via the particular Figure 4 achieved removable cylindrical fastening bolt 20, which protrudes from the housing-side base plate 16, specifically from that side of the latter which defines the housing-side stop surface 14. The outer contour of the fastening bolt 20 is adapted to the inner contour of a through-hole in the lower housing half 3 in the area of the parting line 11, through which the parting joint bolts for connecting the two housing halves extend when the turbine housing is closed.

In den Figuren 1 und 2, welche den Adapter 12 im montierten Zustand zeigen, ist der zylinderförmige Befestigungsbolzen 20 in die Durchgangsbohrung in der unteren Gehäusehälfte 3 eingesteckt und entsprechend nicht sichtbar.In the Figures 1 and 2 which show the adapter 12 in the assembled state, the cylindrical fastening bolt 20 is inserted into the through-hole in the lower housing half 3 and is accordingly not visible.

Die Mittel des Adapters 12 zur Befestigung an dem Gehäuse umfassen neben dem zylinderförmigen Befestigungsbolzen 20 eine in dem Befestigungsbolzen 20, konkret in dessen freier Stirnseite 24, die in den Figuren 4, 6, 7 und 9 nach unten weist, vorgesehene Gewindebohrung 21, eine Schraube 23 und eine Unterlegscheibe 25 (vgl. Figur 9). Die Längsachse der Gewindebohrung 21 und die Längsachse des Befestigungsbolzens 20 liegen aufeinander.The means of the adapter 12 for fastening to the housing include, in addition to the cylindrical fastening bolt 20, one in the fastening bolt 20, specifically in its free end face 24, which is in the Figures 4 , 6th , 7th and 9 pointing downwards, provided threaded hole 21, a screw 23 and a washer 25 (cf. Figure 9 ). The longitudinal axis of the threaded hole 21 and the longitudinal axis of the fastening bolt 20 lie on top of one another.

Der Adapter 12 umfasst weiterhin zur Drehsicherung im montierten Zustand ein von der gehäuseseitigen Grundplatte 16 abragendes zylinderförmiges Sicherungselement 26, welches, wie insbesondere in der Figur 4 erkennbar, einen geringeren Durchmesser und eine geringere Länge aufweist als der zylinderförmige Befestigungsbolzen 20. Das Sicherungselement 26 ist derart ausgebildet und angeordnet, dass es im montierten Zustand des Adapters 12 in eine in der unteren Gehäusehälfte 3 im Bereich der Teilfuge 11 vorhandene Aussparung, vorliegend weitere Durchgangsbohrung eingreift. Das Sicherungselement 26 ist dabei derart ausgebildet, dass es im montierten Zustand formschlüssig in der weiteren Durchgangsbohrung sitzt. Bei dem dargestellten Ausführungsbeispiel ist das Sicherungselement 26, wie in Figur 7 erkennbar, in eine in der gehäuseseitigen Grundplatte 16 vorgesehene Öffnung eingesteckt und weist zur axialen Fixierung einen Kopfbereich größeren Durchmessers auf.To prevent rotation in the assembled state, the adapter 12 furthermore comprises a cylindrical securing element 26 protruding from the base plate 16 on the housing side, which, as in particular in FIG Figure 4 recognizable, has a smaller diameter and a smaller length than the cylindrical fastening bolt 20. The securing element 26 is designed and arranged in such a way that, in the assembled state of the adapter 12, it is inserted into a recess present in the lower housing half 3 in the area of the joint 11, in this case further Through hole engages. The securing element 26 is designed in such a way that, in the assembled state, it is seated with a positive fit in the further through hole. In the illustrated embodiment, the securing element 26, as in FIG Figure 7 recognizable, inserted into an opening provided in the housing-side base plate 16 and has a head area of larger diameter for axial fixation.

Für die Befestigung des Adapters 12 an der unteren Gehäusehälfte 3 wurde der Befestigungsbolzen 20 in die im Bereich der Teilfuge 11 vorhandene Durchgangsbohrung von deren Oberseite her eingesteckt und es wurde die Schraube 23 mit darauf liegender Unterlegscheibe 25 von der Unterseite der Durchgangsbohrung her in die Gewindebohrung 21 in dem Befestigungsbolzen 20 eingeschraubt.To fasten the adapter 12 to the lower housing half 3, the fastening bolt 20 was inserted into the through-hole in the area of the parting line 11 from the top thereof, and the screw 23 with a washer 25 on it was inserted into the threaded hole 21 from the underside of the through-hole screwed into the fastening bolt 20.

Soll der Kran 5 an einem Turbinengehäuse befestigt werden, welches sich durch Durchgangsbohrungen anderer Dimensionen und/oder Positionen, also durch ein anderes Bohrmuster im Bereich der Teilfuge auszeichnet, kann einfach ein anderer Adapter bereitgestellt werden, dessen Befestigungsbolzen und Sicherheitselement derart ausgebildet und angeordnet sind, dass sie zu dem anderen Bohrmuster passen.If the crane 5 is to be fastened to a turbine housing which is characterized by through-bores of different dimensions and / or positions, i.e. by a different drilling pattern in the area of the parting line, another adapter can simply be provided whose fastening bolts and safety element are designed and arranged in such a way that that they match the other drilling pattern.

Der auf die vorstehend beschriebene Weise über den Adapter 12 an der unteren Gehäusehälfte 3 befestigte Kran 5 kommt, wie vorstehend angemerkt, im Rahmen der Demontage der Laufschaufeln 4 zum Einsatz.The crane 5, which is fastened to the lower housing half 3 via the adapter 12 in the manner described above, is used, as noted above, in the course of dismantling the rotor blades 4.

Zusätzlich zu dem Kran 5 ist, wie in der Figur 1 erkennbar, eine Arbeitsplattform 27 an dem Turbinengehäuse, konkret der unteren Gehäusehälfte 3 im Bereich der Teilfuge 11 befestigt worden, welche ein Monteur betreten kann, um Laufschaufel-Demontagearbeiten durchzuführen und den Kran 5 über eine in den Figuren nicht dargestellte, an dem Kran 5 vorgesehene Bedieneinheit zu steuern.In addition to the crane 5, as in FIG Figure 1 recognizable, a working platform 27 has been attached to the turbine housing, specifically the lower housing half 3 in the area of the parting line 11, which a fitter can enter to carry out blade dismantling work and the crane 5 via a not shown in the figures provided on the crane 5 Control unit.

Für die Demontage einer Laufschaufel 4 wird diese zunächst durch entsprechende Positionierung des Läufers der Turbine 1 in 12-Uhr-Position gebracht. Eine Laufschaufel 4 in dieser Position kann der Figur 1 entnommen werden. Anschließend wird der Ausleger 7 des Krans 5 von einem auf der Arbeitsplattform 27 stehenden Monteur derart in Position gebracht, dass sich das freie Ende des Auslegers 7 zumindest in etwa oberhalb der auszubauenden Laufschaufel 4 befindet, wie es in Figur 1 dargestellt ist. Die Laufschaufel 4 wird mittels des an dem Seil 9 befestigten Greifers gegriffen und aus der Einbauposition herausgebracht. Dies kann allein durch die Steuerung des Krans 5 erfolgen oder durch händischen Eingriff durch den Monteur, wobei der Monteur niemals das komplette Gewicht der Laufschaufel 4 von etwa 45 kg tragen muss, sondern allenfalls eine Bewegung der Laufschaufel 4 bewirkt, während diese von dem Kran 5 getragen wird. Die aus ihrer Einbauposition entfernte Laufschaufel 4 kann mit dem Kran 5 zu der Arbeitsplattform 27 oder auch zu einem anderen Ablageort neben der Turbine 1 gebracht werden.To dismantle a rotor blade 4, it is first brought into the 12 o'clock position by positioning the rotor of the turbine 1 accordingly. A blade 4 in this position can Figure 1 can be removed. The boom 7 of the crane 5 is then brought into position by a fitter standing on the work platform 27 in such a way that the free end of the boom 7 is at least approximately above the moving blade 4 to be removed, as shown in FIG Figure 1 is shown. The rotor blade 4 is gripped by means of the gripper attached to the rope 9 and brought out of the installation position. This can be done solely by controlling the crane 5 or by manual intervention by the fitter, whereby the fitter never has to carry the entire weight of the rotor blade 4 of around 45 kg, but at most causes a movement of the rotor blade 4 while it is being operated by the crane 5 will be carried. The moving blade 4, which has been removed from its installation position, can be brought with the crane 5 to the work platform 27 or to another storage location next to the turbine 1.

Nachdem insbesondere sämtliche Laufschaufeln 4 auf diese Weise entfernt wurden können weitere Arbeiten mit Hilfe des Krans 5 durchgeführt werden, die sowohl den Aus- als auch den Einbau von Schaufeln oder auch anderen Komponenten der Turbine 1 einschließen können und, wenn der Kran 5 nicht mehr benötigt wird, kann dieser wieder von der unteren gehäusehälfte 3 entfernt werden, indem die in den zylinderförmigen Befestigungszylinder 21 eingeschraubte Schraube 23 herausgedreht und der Kran 5 angehoben und somit der Befestigungsbolzen 20 aus der Durchgangsbohrung in der unteren Gehäusehälfte 3 entfernt wird.After all the rotor blades 4 have been removed in this way, further work can be carried out with the aid of the crane 5, which can include both the removal and installation of blades or other components of the turbine 1 and when the crane 5 is no longer required it can be removed again from the lower housing half 3 by unscrewing the screw 23 screwed into the cylindrical fastening cylinder 21 and lifting the crane 5 and thus removing the fastening bolt 20 from the through-hole in the lower housing half 3.

Unter Durchführung des erfindungsgemäßen Verfahrens bzw. die erfindungsgemäße Verwendung eines vorübergehend an der unteren Gehäusehälfte 3 befestigten Krans 5 wird ein besonders sicheres Handling von Turbinenkomponenten und somit eine besonders hohe Arbeitssicherheit möglich.By carrying out the method according to the invention or the use according to the invention of a crane 5 temporarily fastened to the lower housing half 3, a particularly safe handling of turbine components and thus a particularly high level of work safety is possible.
