Definitions

  • the present invention relates to a device for installing and removing a component of a gas turbine, and a method for using such a device.
  • Such devices as in the EP 2 045 472 A1 are typically required for maintenance work on a gas turbine, for example in order to be able to replace machine or bearing components of the gas turbine.
  • bearing components or components that are operatively connected to them can be removed from the gas turbine without having to completely disassemble the gas turbine.
  • a device for installing or removing bearing components on the gas turbine which is designed for attachment to the gas turbine end as a rail system, wherein a mounting plate is attached to the housing of the gas turbine.
  • the rail system here comprises two running rails on which the bearing or other components can be supported directly.
  • the supporting force of the rotor of the gas turbine on the bearing is reduced by suitable measures, as a result of which the load on the bearing is reduced to such an extent that it can be removed by scraping over the end of the rotor.
  • the bearing is supported by means of the two running rails, so that the weight of the bearing does not have to be supported by the maintenance personnel or other devices. In addition to a controlled removal of the bearing, this also allows the subsequent handling to be carried out in a controlled and safe manner.
  • the problem with the device known from the prior art is that the maintenance measures in the area of the bearing of a gas turbine sometimes require the removal of several components from the gas turbine.
  • the rigid fastening of the running rails to the housing of the gas turbine only enables the controlled and safe removal of those components which have a suitable alignment with the running rails.
  • the running rails are aligned such that when the bearing is pulled off the end of the rotor, the outer wall of the main bearing body can be supported by the running rails without further height adjustment.
  • the object on which the invention is based is achieved by a device for installing and removing a Component of a gas turbine, comprising a rail system with at least two running rails, a running carriage being provided on the running rails, which carriage can be displaced on the running rails along a predetermined displacement axis, the running carriage having a fixing device which is designed to form a fitting section of a first carriage insert to determine in a force-fit manner that when the carriage is moved on the rails, the first carriage insert is also displaced, the carriage having a height adjustment which is designed to adjust the height of the fixing device when the device is used as intended.
  • the height relates to a direction which is typically oriented parallel to the direction of the gravitational field.
  • the carriage thus allows a flexible adaptation to different components which have to be removed from the gas turbine or installed in the gas turbine at different height levels, for example, without having to replace the respective car insert.
  • the present invention comprises at least two running rails, preferably exactly two running rails.
  • the component of the gas turbine to be installed or removed is in particular part of the rotor or the housing or the bearing of the gas turbine, which is preferably provided in the region of the ends of the gas turbine at the bearing sections.
  • the device itself is provided in particular for fastening in the region of the rotor end of the gas turbine, suitable fastening devices for attachment to the gas turbine being already known from the prior art.
  • the rail system is attached to the gas turbine in such a way that the carriage can be displaced relative to the rail system and relative to the gas turbine along an axis of displacement. If the rail system is provided for installing or removing bearing components on the gas turbine, it is typically attached to the end of the gas turbine in the region of the housing, so that the displacement axis runs parallel to the longitudinal axis of the rotor of the gas turbine.
  • the carriage is used to support the weight of the component and introduce it into the rail system compared to the rail system.
  • the carriage allows a suitable distribution of the weight of the respective component over the at least two rails.
  • the component in question is itself supported on the first carriage insert, or, as further explained below, on a second carriage insert, so that the weight of the respective component can be derived from the carriage insert on the carriage into the running rails.
  • the carriage insert itself is preferably adapted to the geometry of the component that is to be installed or removed.
  • the wagon insert a suitable geometry so that when the carriage insert is properly arranged on the carriage and the carriage on the running rails, the respective component from the gas turbine can be placed directly on the carriage insert without any additional device for raising or lowering the component.
  • each component can now be assigned its own car insert, so that the problem-free removal of all components from the gas turbine can be promoted in succession by selecting the respective car inserts.
  • the device according to the invention has, in addition to the running rails and the carriage, also a first carriage insert, or alternatively also a second carriage insert, the entirety of all components being understood as a system. In other words, the components mentioned are encompassed by the respective device.
  • the carriage has a suitable fixing device which is shaped in such a way that a fitting section of the first carriage insert can be non-positively connected to the carriage, so that when the carriage is moved on the rails, the first carriage insert with the respective itself component located on it is also moved. Due to the provision of a fitting section, which brings about a positive connection and through which the non-positive connection of the carriage and carriage insert is made possible, the respective carriage insert can advantageously be connected to the carriage. It is important to quickly insert or remove the first carriage insert from the carriage because this means that different carriage inserts for different components can be quickly and easily replaced on the carriage.
  • individual carriage inserts can be provided for the individual components, which can be inserted into the carriage quickly and without great loss of time. After work has been carried out or after a component has been removed and installed, the next carriage insert can be inserted into the carriage and the sequence of individual work steps can be supported in a geometrically adapted manner.
  • the first carriage insert is connected to the carriage exclusively via surface contact of its fitting section, and in particular a further connection of the two is not provided.
  • a further connection could be a screw connection, which is not provided in the embodiment.
  • only the surface contact is sufficient to bring about a frictional connection between the carriage and the first carriage use, both of which can be quickly and easily connected to one another as intended and disassembled again.
  • the fixing device is designed as one or more cross struts between two slide sections of the carriage, the cross struts and regions of the fitting section of the first carriage insert being able to engage with one another.
  • the slide sections are provided so that they can each be moved on a running rail and thus form the contact sections between the running rails and the carriage.
  • a slide section is typically assigned to each running rail.
  • the slide sections typically have ball rollers or cylindrical rollers, the slide sections being able to be moved accordingly along the slide axis described above.

  • the fitting section of the first carriage section is geometrically shaped in such a way that it achieves a suitable frictional connection with the cross strut / cross struts, provided that the first carriage insert was used as intended in the carriage. If several cross struts are provided, the fitting section can engage between the individual cross struts and, for example, completely fill the space section between the cross struts. Correspondingly, a contact closure is achieved, the required frictional connection being ensured with corresponding displacement along the displacement axis.
  • the required adhesion only has to be present when force is applied in predetermined directions.
  • this must be parallel to the axis of displacement when force is exerted in order to be able to easily remove the first carriage insert from the carriage again.
  • there must be no non-positive connection, since otherwise a quick and uncomplicated exchange of the carriage insert would not be possible.

  • the second carriage insert can also only serve to suitably change the height level of the first carriage insert, for example in order to be able to install and remove a component which has to be supported and shifted to a different height level.
  • the second carriage insert is particularly suitable for relatively complex shaped components which have to be inserted into or removed from the gas turbine, which need not be supported, for example, by one bearing surface but by several different bearing surfaces when moving.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Einbauen und Ausbauen eines Bauteils einer Gasturbine, sowie ein Verfahren zur Nutzung einer solchen Vorrichtung.The present invention relates to a device for installing and removing a component of a gas turbine, and a method for using such a device.

Derartige Vorrichtungen , wie in der EP 2 045 472 A1 offenbart, werden typischerweise bei Wartungsarbeiten an einer Gasturbine benötigt, um etwa Maschinen- bzw. Lagerbauteile der Gasturbine austauschen zu können. Insbesondere bei Wartungsmaßnahmen an den Lagerbauteilen einer Gasturbine ist es erforderlich, dass Lager- bzw. damit in Wirkverbindung stehende Bauteile aus der Gasturbine entfernt werden können, ohne die Gasturbine vollständig zerlegen zu müssen.Such devices, as in the EP 2 045 472 A1 are typically required for maintenance work on a gas turbine, for example in order to be able to replace machine or bearing components of the gas turbine. Particularly in the case of maintenance measures on the bearing components of a gas turbine, it is necessary that bearing components or components that are operatively connected to them can be removed from the gas turbine without having to completely disassemble the gas turbine.

So ist etwa aus der WO 2013/098028 A1 eine Vorrichtung zum Ein- bzw. Ausbauen von Lagerbauteilen an der Gasturbine bekannt, welche zur Befestigung am Gasturbinenende als Schienensystem ausgebildet ist, wobei eine Befestigungsplatte an dem Gehäuse der Gasturbine angebracht ist. Das Schienensystem umfasst hierbei zwei Laufschienen, auf welchen das Lager bzw. andere Bauteile direkt abgestützt werden können. Um das Lager etwa aus der Gasturbine zu entfernen, wird durch geeignete Maßnahmen die Abstützkraft des Rotors der Gasturbine auf dem Lager vermindert, wodurch die Belastung des Lagers soweit reduziert wird, dass dieses durch Abstreifen über das Ende des Rotors entfernt werden kann. Bei dem Vorgang des Entfernens wird das Lager mit Hilfe der beiden Laufschienen abgestützt, so dass die Gewichtskraft des Lagers nicht durch das Wartungspersonal oder andere Vorrichtungen abgestützt werden muss. Dies erlaubt neben einer kontrollierten Entfernung des Lagers auch die nachfolgende Handhabung kontrolliert und sicher vorzunehmen.So is from the WO 2013/098028 A1 a device for installing or removing bearing components on the gas turbine is known, which is designed for attachment to the gas turbine end as a rail system, wherein a mounting plate is attached to the housing of the gas turbine. The rail system here comprises two running rails on which the bearing or other components can be supported directly. In order to remove the bearing from the gas turbine, for example, the supporting force of the rotor of the gas turbine on the bearing is reduced by suitable measures, as a result of which the load on the bearing is reduced to such an extent that it can be removed by scraping over the end of the rotor. During the removal process, the bearing is supported by means of the two running rails, so that the weight of the bearing does not have to be supported by the maintenance personnel or other devices. In addition to a controlled removal of the bearing, this also allows the subsequent handling to be carried out in a controlled and safe manner.

Problematisch an der aus dem Stand der Technik bekannten Vorrichtung ist jedoch, dass die Wartungsmaßnahmen im Bereich des Lagers einer Gasturbine mitunter die Entfernung mehrerer Bauteile aus der Gasturbine erfordern. Die starre Befestigung der Laufschienen am Gehäuse der Gasturbine ermöglicht jedoch nur die kontrollierte und sichere Entfernung derjenigen Bauteile, welche eine geeignete Ausrichtung zu den Laufschienen aufweisen. So sind die Laufschienen etwa derart ausgefluchtet, dass bei Abziehen des Lagers über das Ende des Rotors die Außenwandung des Hauptlagerkörpers ohne weitere Höhenanpassung durch die Laufschienen abgestützt werden kann. Weitere Bauteile, welche etwa an dem Rotor bzw. auch in dem Lagerbereich angebracht sind, die jedoch keine geeignete Ausfluchtung zu den Laufschienen aufweisen, müssten somit für die Abstützung durch die beiden Laufschienen zunächst gehoben bzw. abgesenkt werden, um nachfolgend auf den Laufschienen abgestützt werden zu können. Bei verhältnismäßig schweren Bauteilen, welche bei unsachgemäßer Handhabung mechanische Schläge und Krafteinwirkungen erleiden und dadurch beschädigt werden können, stellt diese Art der Handhabung ein Wartungsrisiko dar, welches es zu vermeiden gilt.The problem with the device known from the prior art, however, is that the maintenance measures in the area of the bearing of a gas turbine sometimes require the removal of several components from the gas turbine. The rigid fastening of the running rails to the housing of the gas turbine, however, only enables the controlled and safe removal of those components which have a suitable alignment with the running rails. For example, the running rails are aligned such that when the bearing is pulled off the end of the rotor, the outer wall of the main bearing body can be supported by the running rails without further height adjustment. Further components, which are attached to the rotor or in the bearing area, but which do not have a suitable alignment with the running rails, would therefore first have to be raised or lowered for support by the two running rails in order to subsequently be supported on the running rails to be able to. In the case of relatively heavy components which suffer mechanical impacts and force effects if improperly handled and can be damaged as a result, this type of handling poses a maintenance risk which must be avoided.

Insofern stellt es sich als Aufgabe, eine Vorrichtung zum Einbauen und Ausbauen eines Bauteils einer Gasturbine vorzuschlagen, welches insbesondere für Wartungsarbeiten im Lagerbereich der Gasturbine vorgesehen ist, wobei die Vorrichtung flexibel für den Ein- und Ausbau unterschiedlicher Bauteile sicher verwendet werden kann, deren Anordnung in der Gasturbine insbesondere unterschiedliche Höhenniveaus aufweist. Gleichzeitig soll ein sicheres und kontrolliertes Arbeiten an der Gasturbine ermöglicht werden. Diese der Erfindung zugrundeliegende Aufgabe wird durch eine Vorrichtung gemäß Anspruch 1 sowie durch ein Verfahren gemäß Anspruch 13 gelöst. Insbesondere wird die der Erfindung zugrundeliegende Aufgabe gelöst durch eine Vorrichtung zum Einbauen und Ausbauen eines Bauteils einer Gasturbine, umfassend ein Schienensystem mit wenigstens zwei Laufschienen, wobei auf den Laufschienen ein Laufwagen vorgesehen ist, welcher auf den Laufschienen entlang einer vorbestimmten Verschiebeachse verschoben werden kann, wobei der Laufwagen eine Festlegevorrichtung aufweist, die dazu ausgeformt ist, einen Passabschnitt eines ersten Wageneinsatzes derart kraftschlüssig festzulegen, dass bei Verschieben des Laufwagens auf den Laufschienen der erste Wageneinsatz mit verschoben wird, wobei der Laufwagen eine Höhenverstellung aufweist, welche dazu ausgebildet ist, die Festlegevorrichtung bei bestimmungsgemäßer Nutzung der Vorrichtung in der Höhe zu verstellen. Die Höhe betrifft vorliegend eine Richtung, die typischerweise parallel zur Richtung des Erdanziehungsfeldes orientiert ist. Der Laufwagen erlaubt somit selbst ohne etwa einen Austausch des jeweiligen Wageneinsatzes vornehmen zu müssen, eine flexible Anpassung an unterschiedliche Bauteile, welche etwa auf unterschiedlichen Höhenniveaus aus der Gasturbine aus- bzw. in die Gasturbine eingebaut werden.In this respect, it is the task of proposing a device for installing and removing a component of a gas turbine, which is intended in particular for maintenance work in the storage area of the gas turbine, the device being able to be used flexibly for the installation and removal of different components, the arrangement of which in the gas turbine in particular has different height levels. At the same time, safe and controlled work on the gas turbine is to be made possible. This object on which the invention is based is achieved by a device according to claim 1 and by a method according to claim 13. In particular, the object on which the invention is based is achieved by a device for installing and removing a Component of a gas turbine, comprising a rail system with at least two running rails, a running carriage being provided on the running rails, which carriage can be displaced on the running rails along a predetermined displacement axis, the running carriage having a fixing device which is designed to form a fitting section of a first carriage insert to determine in a force-fit manner that when the carriage is moved on the rails, the first carriage insert is also displaced, the carriage having a height adjustment which is designed to adjust the height of the fixing device when the device is used as intended. In the present case, the height relates to a direction which is typically oriented parallel to the direction of the gravitational field. The carriage thus allows a flexible adaptation to different components which have to be removed from the gas turbine or installed in the gas turbine at different height levels, for example, without having to replace the respective car insert.

Weiterhin wird die der Erfindung zugrundeliegende Aufgabe gelöst durch ein Verfahren zum Nutzen einer vorab wie auch nachfolgend beschriebenen Vorrichtung, wobei folgende Schritte umfasst sind:

  • Bereitstellen eines Schienensystems mit wenigstens zwei Laufschienen, wobei auf den Laufschienen ein Laufwagen vorgesehen ist, welcher auf den Laufschienen entlang einer vorbestimmten Verschiebeachse verschoben werden kann;
  • Befestigen des Schienensystems an einer Gasturbine;
  • Aufsetzen auf den Laufwagen und kraftschlüssiges Festlegen eines ersten Wageneinsatzes mit Hilfe einer Festlegevorrichtung des Laufwagens;
  • Verschieben des Laufwagens auf den Laufschienen, wobei der erste Wageneinsatz ebenfalls mit verschoben wird.
Furthermore, the object on which the invention is based is achieved by a method for using a device described above and below, the following steps being included:
  • Providing a rail system with at least two running rails, a running carriage being provided on the running rails, which carriage can be displaced along a predetermined displacement axis on the running rails;
  • Attaching the rail system to a gas turbine;
  • Placing on the carriage and non-positively fixing a first carriage insert with the help of a fixing device of the carriage;
  • Moving the carriage on the rails, whereby the first carriage insert is also moved.

An dieser Stelle ist darauf hinzuweisen, dass die vorliegende Erfindung wenigstens zwei Laufschienen umfasst, bevorzugt genau zwei Laufschienen.At this point it should be pointed out that the present invention comprises at least two running rails, preferably exactly two running rails.

Ebenfalls ist darauf hinzuweisen, dass das ein- bzw. auszubauende Bauteil der Gasturbine insbesondere ein Teil des Rotors bzw. des Gehäuses oder des Lagers der Gasturbine ist, welches bevorzugt im Bereich der Enden der Gasturbine an den Lagerabschnitten vorgesehen ist. Aber auch andere Teile können bei dem Ein- und Ausbau betroffen sein, wobei diese Teile mit den vorab bezeichneten anderen Bauteilen typischerweise in Wirkverbind stehen. Die Vorrichtung selbst ist insofern insbesondere zur Befestigung im Bereich des Rotorendes der Gasturbine vorgesehen, wobei geeignete Befestigungsvorrichtungen zur Anbringung an der Gasturbine aus dem Stand der Technik bereits bekannt sind.It should also be pointed out that the component of the gas turbine to be installed or removed is in particular part of the rotor or the housing or the bearing of the gas turbine, which is preferably provided in the region of the ends of the gas turbine at the bearing sections. However, other parts can also be affected during the installation and removal, these parts typically being operatively connected to the other components described above. In this respect, the device itself is provided in particular for fastening in the region of the rotor end of the gas turbine, suitable fastening devices for attachment to the gas turbine being already known from the prior art.

Das Schienensystem ist so an der Gasturbine angebracht, dass der Laufwagen relativ zu dem Schienensystem und relativ zu der Gasturbine entlang einer Verschiebeachse verschoben werden kann. Ist das Schienensystem zum Ein- bzw. Ausbauen von Lagerbauteilen an der Gasturbine vorgesehen, wird es typischerweise im Bereich des Gehäuses endständig an der Gasturbine angebracht, so dass die Verschiebeachse parallel zu der Längserstreckungsachse des Rotors der Gasturbine verläuft.The rail system is attached to the gas turbine in such a way that the carriage can be displaced relative to the rail system and relative to the gas turbine along an axis of displacement. If the rail system is provided for installing or removing bearing components on the gas turbine, it is typically attached to the end of the gas turbine in the region of the housing, so that the displacement axis runs parallel to the longitudinal axis of the rotor of the gas turbine.

Der Laufwagen dient der Abstützung des Gewichts des Bauteils und Einleitung in das Schienensystem gegenüber dem Schienensystem. In anderen Worten erlaubt der Laufwagen eine geeignete Verteilung der Gewichtskraft des jeweiligen Bauteils auf die wenigstens zwei Laufschienen. Das betreffende Bauteil wird selbst jeweils auf dem ersten Wageneinsatz, bzw. wie weiter nachfolgend noch ausgeführt, auf einem zweiten Wageneinsatz abgestützt, so dass die Gewichtskraft des jeweiligen Bauteils über den Wageneinsatz auf den Laufwagen in die Laufschienen abgeleitet werden kann. Der Wageneinsatz selbst ist hierbei bevorzugt angepasst an die Geometrie des Bauteils, welches ein- bzw. auszubauen ist. Insbesondere weist der Wageneinsatz eine geeignete Geometrie auf, so dass bei bestimmungsgemäßer Anordnung des Wageneinsatzes auf dem Laufwagen und des Laufwagens auf den Laufschienen das jeweilige Bauteil aus der Gasturbine ohne weitere Vorrichtung zum Anheben bzw. Absenken des Bauteils direkt auf den Wageneinsatz abgelegt werden kann. In anderen Worten dient der Wageneinsatz der geometrischen und niveautechnische Anpassung der Vorrichtung an das jeweils ein- bzw. auszubauende Bauteil. Ausführungsgemäß kann nun bspw. jedem Bauteil ein eigener Wageneinsatz zugeordnet sein, so dass durch Wahl der jeweiligen Wageneinsätze in entsprechender Reihenfolge nacheinander der problemlose Ausbau aller Bauteile aus der Gasturbine gefördert werden kann.The carriage is used to support the weight of the component and introduce it into the rail system compared to the rail system. In other words, the carriage allows a suitable distribution of the weight of the respective component over the at least two rails. The component in question is itself supported on the first carriage insert, or, as further explained below, on a second carriage insert, so that the weight of the respective component can be derived from the carriage insert on the carriage into the running rails. The carriage insert itself is preferably adapted to the geometry of the component that is to be installed or removed. In particular, the wagon insert a suitable geometry so that when the carriage insert is properly arranged on the carriage and the carriage on the running rails, the respective component from the gas turbine can be placed directly on the carriage insert without any additional device for raising or lowering the component. In other words, the use of the trolley serves to adapt the device geometrically and in terms of level technology to the component to be installed or removed. According to the embodiment, each component can now be assigned its own car insert, so that the problem-free removal of all components from the gas turbine can be promoted in succession by selecting the respective car inserts.

An dieser Stelle ist ausdrücklichkeitshalber noch darauf hinzuweisen, dass die erfindungsgemäße Vorrichtung neben den Laufschienen und dem Laufwagen auch einen ersten Wageneinsatz aufweist, bzw. alternativ auch einen zweiten Wageneinsatz, wobei die Gesamtheit aller Bauteile als System zu verstehen ist. In anderen Worten werden die genannten Bauteile von der jeweiligen Vorrichtung umfasst.At this point it should be pointed out expressly that the device according to the invention has, in addition to the running rails and the carriage, also a first carriage insert, or alternatively also a second carriage insert, the entirety of all components being understood as a system. In other words, the components mentioned are encompassed by the respective device.

Weiter sieht die vorliegende Erfindung vor, dass der Laufwagen eine geeignete Festlegevorrichtung aufweist, die so ausgeformt ist, dass ein Passabschnitt des ersten Wageneinsatzes mit dem Laufwagen kraftschlüssig verbunden werden kann, dass bei Verschieben des Laufwagens auf den Laufschienen auch der erste Wageneinsatz mit dem jeweils sich darauf befindlichen Bauteil ebenfalls mit verschoben wird. Aufgrund des Vorsehens eines Passabschnittes, welcher einen Formschluss herbeiführt, und durch welchen die kraftschlüssige Verbindung von Laufwagen und Wageneinsatz ermöglicht ist, kann der jeweilige Wageneinsatz mit dem Laufwagen vorteilhaft verbunden werden. Das schnelle Einsetzen bzw. Entfernen des ersten Wageneinsatzes aus dem Laufwagen ist wichtig, da so unterschiedliche Wageneinsätze für unterschiedliche Bauteile schnell und unkompliziert auf dem Laufwagen ausgetauscht werden können. Werden also etwa verschiedene Bauteile in Folge aus der Gasturbine entfernt, können für die einzelnen Bauteile einzelne Wageneinsätze vorgesehen werden, welche schnell und ohne großen Zeitverlust in den Laufwagen eingesetzt werden können. Nach erfolgter Arbeit bzw. nach erfolgtem Aus- und Einbauen eines Bauteils kann somit der jeweils nächste Wageneinsatz in den Laufwagen eingesetzt werden, und die Folge einzelner Arbeitsschritte kann geometrisch angepasst unterstützt werden.Furthermore, the present invention provides that the carriage has a suitable fixing device which is shaped in such a way that a fitting section of the first carriage insert can be non-positively connected to the carriage, so that when the carriage is moved on the rails, the first carriage insert with the respective itself component located on it is also moved. Due to the provision of a fitting section, which brings about a positive connection and through which the non-positive connection of the carriage and carriage insert is made possible, the respective carriage insert can advantageously be connected to the carriage. It is important to quickly insert or remove the first carriage insert from the carriage because this means that different carriage inserts for different components can be quickly and easily replaced on the carriage. So are different components in succession from the gas turbine removed, individual carriage inserts can be provided for the individual components, which can be inserted into the carriage quickly and without great loss of time. After work has been carried out or after a component has been removed and installed, the next carriage insert can be inserted into the carriage and the sequence of individual work steps can be supported in a geometrically adapted manner.

Gemäß einer ersten Ausführungsform der Vorrichtung ist vorgesehen, dass der erste Wageneinsatz ausschließlich über Flächenkontakt seines Passabschnittes mit dem Laufwagen verbunden ist und insbesondere eine weitergehende Verbindung beider nicht vorgesehen ist. Eine derartige weitergehende Verbindung könnte etwa eine Verschraubung sein, welche ausführungsgemäß nicht vorgesehen ist. Ausführungsgemäß ist ausschließlich der Flächenkontakt ausreichend, um einen Kraftschluss zwischen Laufwagen und erstem Wageneinsatz herbeizuführen, wobei beide schnell und unkompliziert miteinander bestimmungsgemäß verbunden und wieder auseinander gebaut werden können.According to a first embodiment of the device, it is provided that the first carriage insert is connected to the carriage exclusively via surface contact of its fitting section, and in particular a further connection of the two is not provided. Such a further connection could be a screw connection, which is not provided in the embodiment. According to the embodiment, only the surface contact is sufficient to bring about a frictional connection between the carriage and the first carriage use, both of which can be quickly and easily connected to one another as intended and disassembled again.

Gemäß einer weiteren Ausführungsform der erfindungsgemäßen Vorrichtung ist vorgesehen, dass die Festlegevorrichtung als eine oder mehrere Querstreben zwischen zwei Schlittenabschnitten des Laufwagens ausgebildet ist, wobei die Querstreben und Bereiche des Passabschnittes des ersten Wageneinsatzes ineinander eingreifen können. Ausführungsgemäß sind die Schlittenabschnitte dazu vorgesehen, auf jeweils einer Laufschiene verschoben werden zu können und sie bilden damit die Kontaktabschnitte zwischen den Laufschienen und dem Laufwagen. Jeder Laufschiene ist typischerweise ein Schlittenabschnitt zugeordnet. Für das reibungsarme Verschieben der Schlittenabschnitte auf den Laufschienen weisen die letztgenannten typischerweise Kugelrollen bzw. Zylinderrollen auf, wobei die Schlittenabschnitte auf diesen entlang der vorbeschriebenen Verschiebeachse entsprechend bewegt werden können. Die eine bzw. mehreren Querstreben der Festlegevorrichtung erlauben bei Verschieben des Laufwagens eine geeignete Kraftübertragung des ersten Wageneinsatzes auf den Laufwagen bzw. umgekehrt. Der Passabschnitt des ersten Wagenabschnitts ist hierbei geometrisch so ausgeformt, dass er mit der Querstrebe/den Querstreben einen geeigneten Kraftschluss erreicht, soweit der erste Wageneinsatz in den Laufwagen bestimmungsgemäß eingesetzt wurde. Sind mehrere Querstreben vorgesehen, kann der Passabschnitt zwischen die einzelnen Querstreben eingreifen und etwa den Raumabschnitt zwischen den Querstreben vollständig ausfüllen. Dementsprechend ist ein Kontaktschluss erreicht, wobei bei entsprechendem Verschieben entlang der Verschiebeachse der erforderliche Kraftschluss gewährleistet ist. An dieser Stelle ist es hilfreich zu erwähnen, dass der erforderliche Kraftschluss lediglich bei Krafteinwirkung in vorbestimmten Richtungen vorliegen muss. Insbesondere muss dieser bei Krafteinwirkung parallel zur Verschiebeachse gegeben sein, um den ersten Wageneinsatz jedoch aus dem Laufwagen wieder leicht entfernen zu können. So darf weiter bspw. für eine vorbestimmte andere Bewegungsrichtung, also etwa senkrecht zur Richtung der Verschiebeachse, kein Kraftschluss vorliegen, da andernfalls ein schneller und unkomplizierter Austausch des Wageneinsatzes nicht ermöglicht sein würde.According to a further embodiment of the device according to the invention, it is provided that the fixing device is designed as one or more cross struts between two slide sections of the carriage, the cross struts and regions of the fitting section of the first carriage insert being able to engage with one another. According to the embodiment, the slide sections are provided so that they can each be moved on a running rail and thus form the contact sections between the running rails and the carriage. A slide section is typically assigned to each running rail. For the low-friction displacement of the slide sections on the running rails, the latter typically have ball rollers or cylindrical rollers, the slide sections being able to be moved accordingly along the slide axis described above. The one or more cross struts of the fixing device allow a suitable power transmission of the first carriage insert to the carriage when the carriage is moved or vice versa. The fitting section of the first carriage section is geometrically shaped in such a way that it achieves a suitable frictional connection with the cross strut / cross struts, provided that the first carriage insert was used as intended in the carriage. If several cross struts are provided, the fitting section can engage between the individual cross struts and, for example, completely fill the space section between the cross struts. Correspondingly, a contact closure is achieved, the required frictional connection being ensured with corresponding displacement along the displacement axis. At this point it is helpful to mention that the required adhesion only has to be present when force is applied in predetermined directions. In particular, this must be parallel to the axis of displacement when force is exerted in order to be able to easily remove the first carriage insert from the carriage again. Thus, for example, for a predetermined other direction of movement, that is to say perpendicular to the direction of the displacement axis, there must be no non-positive connection, since otherwise a quick and uncomplicated exchange of the carriage insert would not be possible.

Gemäß einer weiteren Ausführungsform ist vorgesehen, dass der erste Wageneinsatz auf der dem Passabschnitt gegenüberliegenden Seite Rollen aufweist. Insbesondere sind dies wenigstens zwei Sätze von parallel zueinander angeordneten Rollen. Die Rollen sind etwa Kugelrollen bzw. Zylinderrollen, die eine Rollbewegung in einer vorbestimmten Richtung bzw. sogar einer vorbestimmten Rollebene ermöglichen. Das mit der ausführungsgemäßen Vorrichtung handzuhabende Bauteil kann also über die Rollen verhältnismäßig leicht auf den ersten Wageneinsatz verschoben werden, wobei nach erfolgtem Verschieben das System aus erstem Wageneinsatz und Laufwagen als Einheit weiter auf den Laufschienen verschoben werden kann. Um etwa das Bauteil auf den ersten Wageneinsatz ablegen zu können, kann der Laufwagen auf dem Schienensystem mittels einer nicht weiter beschriebenen Einheit festgelegt werden, so dass erst nach erfolgtem, erfolgreichem Verschieben des Bauteils auf den ersten Wageneinsatz diese Festlegung wieder aufgehoben wird und das besagte System aus Bauteil, Wageneinsatz und Laufwagen auf den Laufschienen bewegt werden kann. Die Rollen auf dem ersten Wageneinsatz erleichtern also die Bewegung des ein- bzw. auszubauenden Bauteils auf den ersten Wageneinsatz.According to a further embodiment it is provided that the first carriage insert has rollers on the side opposite the fitting section. In particular, these are at least two sets of rollers arranged parallel to one another. The rollers are, for example, ball rollers or cylindrical rollers, which enable a rolling movement in a predetermined direction or even a predetermined roller plane. The component to be handled with the device according to the embodiment can thus be moved relatively easily over the rollers onto the first carriage insert, whereby after the displacement has taken place, the system comprising the first carriage insert and carriage can be moved as a unit on the running rails. In order to be able to place the component on the first carriage insert, for example, the carriage can be fixed on the rail system by means of a unit that is not described further, so that only after the component has been successfully moved onto the first use of the car, this determination is canceled and the said system of component, car insert and carriage can be moved on the rails. The rollers on the first carriage insert thus facilitate the movement of the component to be installed or removed on the first carriage insert.

Gemäß einer weiteren Ausführungsform ist vorgesehen, dass der erste Wageneinsatz auf der dem Passabschnitt gegenüberliegenden Seite einen Formabschnitt aufweist, welcher für den Einsatz eines weiteren, zweiten Wageneinsatzes ausgebildet ist, wobei der zweite Wageneinsatz seinerseits einen Abschnitt aufweist, welcher mit dem Formabschnitt kraftschlüssig verbindbar ist. Wie bereits zwischen dem Laufwagen und dem ersten Wageneinsatz beschrieben, kann auch eine kraftschlüssige Verbindung zwischen dem ersten und dem zweiten Wageneinsatz hergestellt werden. Beide Wageneinsätze sind hierbei nicht weitergehend miteinander verbunden, so dass ein leichtes Entfernen des zweiten Wageneinsatzes aus dem ersten möglich ist. Der zweite Wageneinsatz weist typischerweise eine unterschiedliche Geometrie im Vergleich zum ersten Wageneinsatz auf, die es erlaubt, unterschiedlich geformte Bauteile der Gasturbine mit Hilfe beider Wageneinsätze vorteilhaft abzustützen. Der zweite Wageneinsatz kann aber auch lediglich dazu dienen, dass Höhenniveau des ersten Wageneinsatzes geeignet zu verändern, um etwa ein Bauteil ein- und ausbauen zu können, welches auf einem unterschiedlichen Höhenniveau abgestützt und verschoben werden muss. Der zweite Wageneinsatz eignet sich insbesondere bei verhältnismäßig komplex geformten Bauteilen, welche in die Gasturbine eingesetzt bzw. aus dieser ausgebaut werden müssen, wobei diese etwa nicht durch eine Lagerungsfläche sondern durch mehrere unterschiedliche Lagerungsflächen beim Verschieben abgestützt werden müssen. Diese unterschiedlichen Lagerungsflächen weisen folglich unterschiedliche Höhenniveaus auf, welche etwa durch konzentrisch angeordnete Zylindermäntel unterschiedlicher Radien beschrieben werden können.According to a further embodiment, it is provided that the first carriage insert on the side opposite the fitting section has a shaped section which is designed for the use of a further, second carriage insert, the second carriage insert in turn having a section which can be non-positively connected to the shaped section. As already described between the carriage and the first carriage insert, a non-positive connection can also be established between the first and the second carriage insert. Both carriage inserts are not connected to one another in this case, so that the second carriage insert can be easily removed from the first. The second carriage insert typically has a different geometry compared to the first carriage insert, which makes it possible to advantageously support differently shaped components of the gas turbine with the aid of both carriage inserts. However, the second carriage insert can also only serve to suitably change the height level of the first carriage insert, for example in order to be able to install and remove a component which has to be supported and shifted to a different height level. The second carriage insert is particularly suitable for relatively complex shaped components which have to be inserted into or removed from the gas turbine, which need not be supported, for example, by one bearing surface but by several different bearing surfaces when moving. These different bearing surfaces consequently have different height levels, which can be described, for example, by concentrically arranged cylinder jackets of different radii.

Entsprechend eines weiterführenden Aspektes dieser Ausführungsform kann vorgesehen sein, dass der zweite Wageneinsatz bei bestimmungsgemäßer Nutzung der Vorrichtung der dem Formabschnitt gegenüberliegenden Seite Rollen aufweist. Insbesondere sind es wenigstens zwei Sätze von parallel zueinander angeordneten Rollen bzw. auch einzelnen Rollen. Die Rollen sind etwa Kugelrollen, oder wie vorab erwähnt Zylinderrollen, die eine Rollbewegung in einer vorbestimmten Richtung oder auch in einer Rollebene ermöglichen können. Wie vorab schon erklärt, kann so das mit der Vorrichtung handzuhabende Bauteil leicht auf den Rollen abgelegt und verschoben werden. Gerade beim Einbau von Bauteilen kann so eine schnelle Positionierung des Bauteils mit verhältnismäßig kleinem Kraftaufwand durch das Wartungspersonal erreicht werden.According to a further aspect of this embodiment, it can be provided that the second carriage insert has rollers when the device is used as intended on the side opposite the molding section. In particular, there are at least two sets of roles arranged parallel to one another or also individual roles. The rollers are, for example, ball rollers, or, as mentioned above, cylindrical rollers, which can enable a rolling movement in a predetermined direction or in a roller plane. As already explained in advance, the component to be handled with the device can be easily placed and moved on the rollers. When installing components, maintenance personnel can quickly position the component with relatively little effort.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass der erste Wageneinsatz und/oder der zweite Wageneinsatz spiegelsymmetrisch ausgebildet sind, wobei die Spiegelsymmetrieebene bei bestimmungsgemäßer Nutzung parallel zur Verschiebeachse verläuft. Ganz besonders bevorzugt umfasst die Spiegelsymmetrieebene die Verschiebeachse selbst. Folglich können die Bauteile, welche aus- bzw. eingebaut werden sollen, gut in Bezug auf die Verschiebeachse positioniert werden und das Bedienpersonal muss keine aufwendige Orientierung des Bauteils vornehmen, wodurch die Handhabung des Bauteils signifikant erleichtert gestaltet wird.According to a preferred embodiment of the invention, it is provided that the first carriage insert and / or the second carriage insert are of mirror-symmetrical design, the mirror-symmetry plane running parallel to the displacement axis when used as intended. The mirror symmetry plane very particularly preferably encompasses the displacement axis itself. Consequently, the components which are to be removed or installed can be positioned well in relation to the displacement axis and the operating personnel does not have to carry out a complex orientation of the component, which significantly facilitates the handling of the component is designed.

Gemäß einer Weiterführung können auch der erste Wageneinsatz und/oder der zweite Wageneinsatz wenigstens jeweils eine Rolle auf jeder der einander gegenüberliegenden Seiten aufweisen, welche Seiten durch die Spiegelsymmetrieebene definiert sind. Insbesondere sind es wieder wenigstens zwei Sätze von parallel zueinander angeordneten Rollen, wobei jeweils ein Satz auf jeweils einer Seite der Spiegelsymmetrieebene angeordnet ist. Die Rollen sind etwa Kugelrollen bzw. wieder Zylinderrollen, die eine Rollbewegung in einer vorbestimmten Rollrichtung bzw. einer vorbestimmten Rollebene ermöglichen. Das mit der Vorrichtung handzuhabende Bauteil wird hierbei auf den Rollen abgelegt und kann geeignet für den Ein- bzw. Ausbau verhältnismäßig ohne Kraftaufwand positioniert werden.According to a further development, the first carriage insert and / or the second carriage insert can also have at least one roller on each of the opposite sides, which sides are defined by the plane of mirror symmetry. In particular, there are again at least two sets of rollers arranged parallel to one another, one set being arranged on each side of the mirror symmetry plane. The rollers are, for example, ball rollers or cylindrical rollers again, which enable a rolling movement in a predetermined rolling direction or a predetermined roller plane. The component to be handled with the device is hereby stored on the rollers and can be positioned for installation or removal relatively effortlessly.

Entsprechend einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass bei bestimmungsgemäßer Nutzung der Vorrichtung der zweite Wageneinsatz den ersten Wageneinsatz auf der für die Abstützung eines Bauteils vorgesehenen Seite nur bereichsweise überdeckt. Somit kann das Bauteil auch gegen Flächen von beiden Wageneinsätzen gleichzeitig abgestützt werden. Dies ist insbesondere bei komplex geformten Bauteilen, deren sichere Abstützung nur durch mehrere Abstützflächen erfolgen kann, von Vorteil. Entsprechend der Bauform des jeweiligen Wageneinsatzes bzw. der Kombination verschiedener Wageneinsätze kann so das Bauteil in Bezug auf die Lage der Gasturbine schnell und sicher positioniert werden.According to a further preferred embodiment of the invention, it is provided that when the device is used as intended, the second carriage insert covers the first carriage insert only in regions on the side provided for supporting a component. This means that the component can also be supported against surfaces of both car inserts at the same time. This is particularly advantageous in the case of complex-shaped components, the safe support of which can only be provided by several support surfaces. Depending on the design of the respective car insert or the combination of different car inserts, the component can be quickly and safely positioned in relation to the position of the gas turbine.

Besonders bevorzugt ist die Höhenverstellung in oder an den Schlittenabschnitten des Laufwagens vorgesehen. Alternativ lässt sich auch in Erwägung ziehen, diese Höhenverstellung im Bereich der Festlegevorrichtung vorzusehen, wobei jedoch dann die aus Sicherheitsgründen erforderliche Stabilität des Systems unter Umständen eingeschränkt sein kann, da der Schwerpunkt weiter nach oben verschoben würde. Bevorzugt ist die Höhenverstellung in oder an den Schlittenabschnitten mittels Verstellschrauben ausgeführt, wobei die Verstellschrauben die Höhenverstellung zwischen zwei gegeneinander verschiebbaren Plattenabschnitten vornehmen lassen. Durch die Höhenverstellung in bzw. an den Schlittenabschnitten kann auch eine geeignete horizontale Ausrichtung des Laufwagens erfolgen, so dass die Nivellierung des Laufwagens damit erreicht werden kann.The height adjustment is particularly preferably provided in or on the slide sections of the carriage. Alternatively, it can also be considered to provide this height adjustment in the area of the fixing device, but the stability of the system required for safety reasons may then be restricted under certain circumstances, since the center of gravity would be shifted further up. The height adjustment in or on the slide sections is preferably carried out by means of adjusting screws, the adjusting screws allowing the height adjustment to be carried out between two plate sections which can be displaced relative to one another. The height adjustment in or on the slide sections can also result in a suitable horizontal alignment of the carriage, so that the carriage can be leveled.

Entsprechend einer weiteren Ausführungsform der Erfindung ist vorgesehen, dass das Schienensystem ebenfalls höhenverstellbar ist, wobei die einzelnen Laufschienen bevorzugt nur stufenweise verstellbar sind. Bei stufenweiser Verstellung sind die Stufen bereits auf die erforderlichen Höhen einzelner Bauteile voreingestellt, so dass durch die stufenweise Verstellung ein erleichterter Arbeitsablauf resultiert, wenn etwa unterschiedliche Bauteile nacheinander aus bzw. eingebaut werden müssen. Eine Justierung der jeweiligen Schienenhöhe kann aufgrund der Stufen-Einstellung entfallen, so dass während eines Arbeitsablaufes die neu eingerichtete Höhenverstellung schnell und ohne wesentlichen Zeitverlust erfolgen kann.According to a further embodiment of the invention, it is provided that the rail system is also adjustable in height, the individual running rails preferably being adjustable only in stages. With gradual adjustment, the steps are already individual to the required heights Components are preset so that the step-by-step adjustment results in an easier workflow if, for example, different components have to be removed or installed one after the other. An adjustment of the respective rail height can be omitted due to the step setting, so that the newly set up height adjustment can be carried out quickly and without significant loss of time during a workflow.

Gemäß einer ebenfalls vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass der erste Wageneinsatz und/oder der zweite Wageneinsatz wenigstens eine Rolle, insbesondere zwei Rollen aufweisen, welche höhenverstellbar sind. Eine solche Höhenverstellung kann etwa dadurch erreicht werden, dass die Rollen als Kugelrollen ausgebildet sind, deren zylindrisches Gehäuse in einem passgenauen Sackloch des Wageneinsatzes eingepasst sind. Werden nun zwischen dem Gehäuse der Rollen und dem Boden des Sackloches Abstandsplatten eingelegt, können die Gehäuse der Rollen aus dem Sackloch zum Teil hervorstehen, jedoch weiterhin gegen die Abstandsplatten und damit indirekt gegen den Boden des Sacklochs abgestützt sein. In Folge weisen diese Rollen ein anderes Höhenniveau auf. Die Ausführungsform der Erfindung mit höhenverstellbaren Rollen ist insbesondere dann vorteilhaft, wenn die Höhenunterschiede zwischen den einzelnen Rollen bzw. Rollenpaaren nur gering ist und damit der Einsatz eines zweiten Wageneinsatzes aufgrund seiner geometrischen Ausdehnung nicht in Frage kommt.According to a likewise advantageous embodiment of the invention, it is provided that the first carriage insert and / or the second carriage insert have at least one roller, in particular two rollers, which are adjustable in height. Such a height adjustment can be achieved, for example, in that the rollers are designed as ball rollers, the cylindrical housing of which is fitted in a precisely fitting blind hole in the carriage insert. If spacer plates are now inserted between the housing of the rollers and the bottom of the blind hole, the housing of the rollers can partially protrude from the blind hole, but can still be supported against the spacer plates and thus indirectly against the bottom of the blind hole. As a result, these roles have a different height level. The embodiment of the invention with height-adjustable rollers is particularly advantageous when the height differences between the individual rollers or pairs of rollers are only slight and the use of a second carriage insert is therefore out of the question due to its geometric extension.

Nachfolgend wird die Erfindung anhand einzelner Figuren im Detail näher beschrieben.The invention is described in more detail below with reference to individual figures.

Figur 1 zeigt eine perspektivische Darstellung einer Ausführungsform einer erfindungsgemäßen Vorrichtung 1, welche zum Ausbauen oder Einbauen eines Bauteils 11 (vorliegend nicht gezeigt) einer Gasturbine 10 vorgesehen ist. Das betreffende Bauteil 11 ist bspw. das Lager bzw. damit in Wirkverbindung stehende Bauteile der Gasturbine 10. Figure 1 shows a perspective view of an embodiment of a device 1 according to the invention, which is provided for removing or installing a component 11 (not shown here) of a gas turbine 10. The relevant component 11 is, for example, the bearing or components of the gas turbine 10 that are operatively connected to it.

Die Vorrichtung 1 weist ein Schienensystem 20 auf, welches vorliegend zwei Laufschienen 21 umfasst. Die Laufschienen 21 selbst weisen auf ihrer Oberfläche nicht weiter mit Bezugszeichen versehene Kugelrollen auf, auf welchen ein Laufwagen 30 entlang einer vorbestimmten Verschiebeachse VA verschoben werden kann. Der Laufwagen 30 weist zwei Schlittenabschnitte 32 auf, die jeweils auf den Kugelrollen der einzelnen Laufschienen 21 aufliegen und Rollkontakt haben. Weiterhin weist der Laufwagen 30 eine Festlegevorrichtung 31 auf, welche vorliegend durch drei nicht eigens mit Bezugszeichen versehenen Querstreben ausgebildet ist. Die Querstreben sind von der jeweils benachbarten Querstrebe jeweils gleich beabstandet. Die Querstreben sind zudem mit einem oberen Plattenabschnitt des Schlittenabschnitts 32 verbunden, wobei der obere Plattenabschnitt eine Höhenverstellung 35 aufweist, welche als Verstellschraube 36 ausgebildet ist. Durch geeignetes Verdrehen der Verstellschrauben 36 wird der obere Plattenabschnitt gegen einen unteren Plattenabschnitt des Schlittenabschnitts 32 bewegt, so dass auch die Festlegevorrichtung 31 höhenverstellt wird. Die Verstellschrauben 36 erlauben bspw. eine Justierung des Höhenniveaus des Laufwagens 30 in Bezug etwa auf ein Bauteil, welches in die Gasturbine eingesetzt werden soll bzw. aus dieser ausgebaut werden soll.The device 1 has a rail system 20, which in the present case comprises two running rails 21. The running rails 21 themselves have ball rollers on their surface which are not further provided with reference numerals and on which a carriage 30 can be displaced along a predetermined displacement axis VA. The carriage 30 has two slide sections 32, which each rest on the ball rollers of the individual rails 21 and have rolling contact. Furthermore, the carriage 30 has a fixing device 31, which in the present case is formed by three cross struts which are not specifically provided with reference numerals. The cross struts are equally spaced from the respectively adjacent cross strut. The cross struts are also connected to an upper plate section of the slide section 32, the upper plate section having a height adjustment 35, which is designed as an adjusting screw 36. By suitable twisting of the adjusting screws 36, the upper plate section is moved against a lower plate section of the slide section 32, so that the fixing device 31 is also adjusted in height. The adjusting screws 36 allow, for example, an adjustment of the height level of the carriage 30 with respect to, for example, a component which is to be inserted into the gas turbine or to be removed therefrom.

Weiter umfasst die vorliegende Vorrichtung 1 einen ersten Wageneinsatz 40, welcher zum Einsetzen in den Laufwagen 30 einen geeigneten Passabschnitt 41 aufweist, so dass etwa durch Einsetzen des ersten Wageneinsatzes 40 senkrecht zur Verschiebeachse VA beide, also erster Wageneinsatz 40 und der Laufwagen 30, kraftschlüssig miteinander verbunden werden können. Der Kraftschluss betrifft hierbei eine Krafteinwirkung parallel zur Verschiebeachse VA. Gegenüber anders gerichteten Richtungen einer Krafteinwirkung muss kein Kraftschluss vorliegen. Konkret weist der vorliegende Passabschnitt 41 zwei Vorsprünge auf, welche an Flächen der Querstreben der Festlegevorrichtung 31 anliegen, so dass bei Verschieben des Laufwagens 30 auch etwa der erste Wageneinsatz 40 in Richtung Verschiebeachse verschoben werden kann. Der erste Wageneinsatz 40 weist zudem auf der dem Passabschnitt 41 gegenüberliegenden Seite zwei Sätze an Rollen 42 auf, welche bevorzugt als Kugelrollen ausgebildet sind. Hierbei sind beide Sätze an Rollen 42 jeweils einander gegenüberliegend in Bezug auf eine nicht weiter eingezeichnete Symmetrieebene, welche durch die Verschiebeachse VA verläuft. Ebenso ist der erste Wageneinsatz 40 spiegelsymmetrisch ausgebildet, so dass nun etwa ein ringförmiges bzw. zylinderförmiges Bauteil auf den Rollen 42 des ersten Wageneinsatzes 40 abgelegt werden kann und sich selbst auf dem Wageneinsatz orientiert.Furthermore, the present device 1 comprises a first carriage insert 40, which has a suitable fitting section 41 for insertion into the carriage 30, so that by inserting the first carriage insert 40 perpendicular to the displacement axis VA, both the first carriage insert 40 and the carriage 30 are non-positively connected to one another can be connected. The frictional connection relates to the application of a force parallel to the displacement axis VA. There is no need for a positive connection in relation to directions of force acting in a different direction. Specifically, the present fitting section 41 has two projections which rest on surfaces of the cross struts of the fixing device 31, so that when the carriage 30 is displaced, the first carriage insert 40 can also be displaced in the direction of the displacement axis. The first carriage insert 40 also has, on the side opposite the fitting section 41, two sets of rollers 42, which are preferably designed as ball rollers. Here, both sets of rollers 42 are opposite each other with respect to a plane of symmetry, not shown, which runs through the displacement axis VA. Likewise, the first carriage insert 40 is mirror-symmetrical, so that an annular or cylindrical component can now be placed on the rollers 42 of the first carriage insert 40 and orientates itself on the carriage insert.

Weiterhin weist der erste Wageneinsatz 40 einen Formabschnitt 43 auf der dem Passabschnitt 41 gegenüberliegenden Seite auf, welcher vorliegend etwa lediglich als Nut ausgebildet ist, welche senkrecht zur Verschiebeachse VA verläuft. In diese Nut kann nun wiederum ein geeignet ausgeformter Abschnitt eines zweiten Wageneinsatzes 50 eingepasst werden, so dass der zweite Wageneinsatz 50 bei Krafteinwirkung in Richtung der Verschiebeachse VA nicht gegen den ersten Wageneinsatz 40 verschoben werden kann. Der zweite Wageneinsatz 50 überdeckt nach entsprechender Anbringung auf dem ersten Wageneinsatz 40 dessen Oberfläche teilweise, welche für die Abstützung eines ein- bzw. auszubauenden Bauteils vorgesehen ist. Der zweite Wageneinsatz 50 weist wiederum, vergleichbar dem ersten Wageneinsatz 40 zwei Rollen 52 auf, welche ebenfalls wiederum auf unterschiedlichen Seiten der vorab bezeichneten Spiegelsymmetrieebene angeordnet sind. Ist nun ein Bauteil nicht derart ausgeformt, dass es auf lediglich einer Abstützfläche abgelegt werden kann, sondern benötigt die Abstützung über mehrere auf einem unterschiedlichen Höhenniveau angebrachte Flächen, so kann ein Teil des Bauteils etwa auf dem ersten Wageneinsatz 40 und ein weiterer Teil auf dem zweiten Wageneinsatz 50 abgestützt werden. Die Kombination beider Wageneinsätze 40 und 50 erlaubt somit auch komplexer geformte Bauteile sicher abzustützen.Furthermore, the first carriage insert 40 has a shaped section 43 on the side opposite the fitting section 41, which in the present case is merely designed as a groove which runs perpendicular to the displacement axis VA. A suitably shaped section of a second carriage insert 50 are fitted so that the second carriage insert 50 cannot be displaced against the first carriage insert 40 when force is applied in the direction of the displacement axis VA. After appropriate attachment to the first carriage insert 40, the second carriage insert 50 partially covers its surface, which is provided for supporting a component to be installed or removed. The second carriage insert 50, in turn, has two rollers 52, comparable to the first carriage insert 40, which in turn are also arranged on different sides of the mirror symmetry plane described above. If a component is not shaped in such a way that it can be placed on only one support surface, but requires support over several surfaces attached at different heights, a part of the component can be placed on the first carriage insert 40 and another part on the second Car insert 50 are supported. The combination of both carriage inserts 40 and 50 thus also allows complex components to be securely supported.

Figur 2 zeigt einen Teilaspekt einer Ausführungsform des Laufwagens 30, wie er etwa in der vorab gezeigten Ausführungsform gemäß Figur 1 vorgesehen sein kann. Hierbei verdeutlicht insbesondere der vergrößerte Bildabschnitt das Prinzip der Höhenverstellung 35 mithilfe der vorab schon beschriebenen Verstellschrauben 36. Die Verstellschrauben 36 bewegen etwa einen oberen Plattenabschnitt (nicht mit Bezugszeichen versehen) gegen einen weiter unten liegenden Plattenabschnitt (ebenfalls nicht mit Bezugszeichen versehen), so dass bei Verdrehen der jeweiligen Verstellschrauben beide Plattenabschnitte gegeneinander bewegt werden können. Die Bewegung der unterschiedlichen Plattenabschnitte erreicht eine Höhenverstellung der Festlegevorrichtung 31 des Laufwagens 30 und erlaubt somit etwa eine Justierung der Höheneinstellung des Laufwagens 30. Figure 2 FIG. 12 shows a partial aspect of an embodiment of the carriage 30, such as that shown in the previously shown embodiment Figure 1 can be provided. The enlarged image section in particular illustrates the principle of the height adjustment 35 with the aid of the adjustment screws 36 already described above. The adjustment screws 36 move approximately an upper plate section (not provided with reference numerals) against a plate section located further below (likewise not provided with reference numerals), so that at Turning the respective adjustment screws can move both plate sections against each other. The movement of the different plate sections reaches a height adjustment of the fixing device 31 of the carriage 30 and thus permits, for example, an adjustment of the height adjustment of the carriage 30.

Figur 3 zeigt ein Detailmerkmal eines ersten Wageneinsatzes 40 mit höhenverstellbaren Rollen 42. Insbesondere weist der erste Wageneinsatz 40 zwei Paare an höhenverstellbaren Rollen 42 auf, welche auf der dem Passabschnitt 41 gegenüberliegenden Seite angeordnet sind. Die Rollen 42 sind als Kugelrollen ausgebildet, welche ein zylindrisches Gehäuse 45 aufweisen, das jeweils in einem Sacklock 44 in dem Wageneinsatz 40 versenkt ist. Figure 3 shows a detailed feature of a first carriage insert 40 with height-adjustable rollers 42. In particular, the First carriage insert 40 has two pairs of height-adjustable rollers 42, which are arranged on the side opposite the fitting section 41. The rollers 42 are designed as ball rollers, which have a cylindrical housing 45, each of which is countersunk in a sack lock 44 in the carriage insert 40.

Eine Höhenverstellung der Rollen 42 kann nun dadurch erreicht werden, dass die Rollen 42 aus dem Sackloch 44 zeitweise entfernt werden, um zwischen dem Gehäuse 45 der Rollen 42 und dem Boden des Sackloches 44 Abstandsplatten (vorliegend nicht gezeigt) einzulegen. Anschließend werden die Rollen 42 wieder bestimmungsgemäß eingesetzt, so dass die Gehäuse 45 der Rollen 42 aus dem Sackloch 44 zum Teil hervorstehen, jedoch weiterhin gegen die Abstandsplatten und damit indirekt gegen den Boden des Sacklochs 44 abgestützt sind. Je nach Dicke der Abstandsplatten können so auch nur geringe Höhenunterschiede zwischen den einzelnen Rollen 42 ausgeglichen werden, bzw. es können auch gewünschte, geringe Höhenunterschiede auch dann realisiert werden, wenn der Einsatz eines zweiten Wageneinsatzes 50 (vorliegend nicht gezeigt) aufgrund seiner Ausdehnung nicht in Frage kommt.A height adjustment of the rollers 42 can now be achieved in that the rollers 42 are temporarily removed from the blind hole 44 in order to insert spacer plates (not shown here) between the housing 45 of the rollers 42 and the bottom of the blind hole 44. The rollers 42 are then used again as intended, so that the housings 45 of the rollers 42 partially protrude from the blind hole 44, but are still supported against the spacer plates and thus indirectly against the bottom of the blind hole 44. Depending on the thickness of the spacer plates, only slight differences in height between the individual rollers 42 can be compensated for, or desired, small differences in height can also be realized if the use of a second carriage insert 50 (not shown here) is not possible due to its expansion Question is coming.
