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, as well as a rail system as it is known from such a device.
- Such devices are typically required for maintenance work on a gas turbine in order to exchange about engine or bearing components of the gas turbine can.
- WO 2013/098028 A1 discloses 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 rails on which the bearing or other components can be supported directly.
- the support force of the rotor of the gas turbine is reduced by appropriate measures on the bearing, whereby the load of the bearing is reduced so much that it can be removed by stripping the end of the rotor.
- the bearing is supported by means of the two rails, so that the weight of the bearing does not have to be supported by the maintenance personnel or other devices.
- a device for installing and removing a Component of a gas turbine comprising a rail system with at least two rails, wherein on the rails a carriage is provided, which can be moved on the rails along a predetermined displacement axis, wherein the carriage has a fixing device, which is formed to a fitting portion of a first car use set so strong that when moving the carriage on the rails of the first car use is moved with.
- the object underlying the invention is achieved by a rail system with at least two rails, wherein on the rails a carriage is provided, which can be moved on the rails along a predetermined displacement axis, wherein a height adjustment is provided in or on carriage sections of the carriage, the allowed to adjust a fixing device of the carriage in accordance with the intended use of the rail system in height.
- the present invention comprises at least two rails, preferably exactly two rails.
- the component of the gas turbine to be installed or removed is, in particular, a part of the rotor or of the housing or of the bearing of the gas turbine, which is preferably provided on the bearing sections in the region of the ends of the gas turbine.
- the device itself is provided in particular for attachment in the region of the rotor end of the gas turbine, suitable fastening devices for attachment to the gas turbine of the prior art being already known.
- the rail system is mounted on the gas turbine such that the carriage can be displaced relative to the rail system and relative to the gas turbine along a displacement axis. If the rail system is provided for mounting or dismounting bearing components on the gas turbine, it is typically attached end-to-end to 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 serves to support the weight of the component and initiate the rail system relative to the rail system.
- the carriage allows a suitable distribution of the weight of the respective component on the at least two rails.
- the relevant component itself is supported in each case on the first vehicle insert, or as further explained below, on a second carriage insert, so that the weight of the respective component can be discharged via the carriage insert onto the carriage into the running rails.
- the car insert itself is preferably adapted to the geometry of the component, which is to be installed or removed.
- the carriage insert has a suitable geometry, so that when the arrangement of the car insert on the carriage and the carriage on the rails the respective component from the gas turbine without further device for raising or lowering the component can be stored directly on the car use.
- each component can be assigned its own vehicle insert, so that the choice of the respective vehicle inserts in a corresponding order one after the other, the problem-free removal of all components from the gas turbine can be promoted.
- the device according to the invention in addition to the rails and the carriage also has a first car use, or alternatively also a second car use, the entirety of all components is to be understood as a system. In other words, said components are included in the respective device.
- the present invention provides that the carriage has a suitable fixing device which is formed so that a fitting portion of the first carriage insert can be frictionally connected to the carriage that when moving the carriage on the rails and the first car use with the each component on it is also moved with. Due to the provision of a fitting portion, which brings about a form fit, and by which the non-positive connection of the carriage and the car insert is made possible, the respective car use can be advantageously connected to the carriage.
- the rapid insertion or removal of the first carriage insert from the carriage is important because so different car inserts for different components can be quickly and easily replaced on the carriage. Become So about different components in a row removed from the gas turbine, individual car inserts can be provided for the individual components, which can be used quickly and without much loss of time in the carriage.
- each next car use can be used in the carriage, and the sequence of individual steps can be supported geometrically adjusted.
- a further connection could be a screw connection, for example, which according to the embodiment is not provided.
- only the surface contact is sufficient to bring about a frictional connection between the carriage and the first carriage insert, wherein both can be quickly and easily connected to each other as intended and then disassembled.
- the fixing device is formed as one or more cross struts between two carriage sections of the carriage, wherein the transverse struts and areas of the fitting portion of the first carriage insert can engage with each other.
- the carriage sections are intended to be able to be displaced on in each case one track rail and thus form the contact sections between the track rails and the carriage.
- Each track is typically associated with a carriage section.
- the carriage sections typically have ball rollers or cylindrical rollers, wherein the carriage sections can be moved in accordance therewith along the above-described displacement axis.
- the one or more cross struts of the fixing device allow for moving the carriage a suitable Power transmission of the first car use on the carriage or vice versa.
- the fitting section of the first carriage section is in this case geometrically shaped such that it reaches a suitable frictional connection with the transverse strut / the transverse struts insofar as the first carriage insert was used as intended in the carriage. If a plurality of transverse struts are provided, the fitting section can engage between the individual transverse struts and completely fill, for example, the space section between the transverse struts. Accordingly, a contact closure is achieved, which is ensured with appropriate displacement along the displacement axis of the required adhesion.
- the required adhesion must be present only when force is applied in predetermined directions. In particular, this must be given when force parallel to the displacement axis in order to easily remove the first car use from the carriage again. Thus, for example, there must be no frictional connection for a predetermined other direction of movement, ie approximately perpendicular to the direction of the displacement axis, since otherwise a quick and uncomplicated replacement of the carriage insert would not be possible.
- the first carriage insert has rollers on the side opposite the fitting section.
- these are at least two sets of rollers arranged parallel to one another.
- the rollers are about ball rollers or cylindrical rollers, which allow a rolling movement in a predetermined direction or even a predetermined roller plane.

- the carriage In order to store about the component on the first car use, the carriage can be set on the rail system by means of a unit not further described, so that only after Successful moving the component on the first car use this determination is canceled again and said system of component, car and carriage can be moved on the rails.
- the roles on the first car use so facilitate the movement of the component to be built in or out on the first car use.
- the first carriage insert on the side opposite the fitting section has a mold section which is designed for the use of a further, second carriage insert, wherein the second carriage insert in turn has a section which can be frictionally connected to the mold section is.
- a non-positive connection between the first and the second car use can be made.
- Both car mats are not further connected to each other, so that an easy removal of the second car insert from the first is possible lent.
- the second car insert typically has a different geometry compared to the first car insert, which allows to advantageously support differently shaped components of the gas turbine with the aid of both car missions.
- the second carriage insert can also only serve to suitably change the height level of the first vehicle insert in order to be able to install and remove a component, for example, which must be supported and moved at a different height level.
- the second carriage insert is particularly suitable for relatively complex-shaped components, which must be used in the gas turbine or removed from this, which need not be supported by a storage surface but rather by several different storage surfaces when moving. Consequently, these different bearing surfaces have different height levels, which can be described for example by concentrically arranged cylinder liners of different radii.
- the second carriage insert has rollers for the intended use of the device of the opposite side of the mold section.
- rollers there are at least two sets of rollers arranged parallel to one another or also individual rollers.
- the rollers are about ball rollers, or as mentioned above cylindrical rollers that can allow a rolling motion in a predetermined direction or in a roller plane.
- ball rollers or as mentioned above cylindrical rollers that can allow a rolling motion in a predetermined direction or in a roller plane.
- the first carriage insert and / or the second carriage insert are mirror-symmetrical, wherein the mirror symmetry plane runs parallel to the displacement axis during intended use.
- the mirror symmetry plane very particularly preferably comprises 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 do not have to undertake a complex orientation of the component, whereby the handling the component is made significantly easier.
- the first carriage insert and / or the second carriage insert can also each have at least one roller on each of the mutually opposite sides, which sides are defined by the mirror symmetry plane.
- the rollers are about ball rollers or cylindrical rollers again, which allow a rolling movement in a predetermined rolling direction or a predetermined roller plane.
- the device to be handled with the device is hereby placed on the rollers and can be positioned suitable for installation or removal relatively effortlessly.
- the second carriage insert when the device is used as intended, only partially covers the first carriage insert on the side provided for supporting a component.
- the component can also be supported simultaneously against surfaces of both wagon inserts. This is particularly advantageous in the case of complex-shaped components whose secure support can only be achieved by means of a plurality of support surfaces. According to the design of the respective car use or the combination of different car inserts so the component can be positioned quickly and safely with respect to the position of the gas turbine.
- the carriage may also have a height adjustment, which is designed to adjust the fixing device in the intended use of the device in height.
- the height relates to a direction which is typically oriented parallel to the direction of the gravitational field.
- the height adjustment is provided in or on the carriage sections of the carriage.
- it may also be considered to provide this height adjustment in the area of the fixing device, but in that case the stability of the system required for safety reasons may possibly be limited, since the center of gravity would be shifted further upwards.
- the height adjustment in or on the carriage sections by means Adjustment screws running, the adjusting screws make the height adjustment between two mutually displaceable plate sections. Due to the height adjustment in or on the carriage sections, a suitable horizontal alignment of the carriage can also take place so that the leveling of the carriage can be achieved thereby.
- the rail system is also adjustable in height, wherein the individual rails are preferably only gradually adjustable.
- the stages are already preset to the required heights of individual components, so that the step-by-step displacement results in a simplified workflow, when, 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 during a workflow, the newly established height adjustment can be done quickly and without significant loss of time.
- the first carriage insert and / or the second carriage insert have at least one roller, in particular two rollers, which are height-adjustable.
- a height adjustment can be achieved, for example, in that the rollers are designed as ball rollers whose cylindrical housing is fitted in a precisely fitting blind hole of the carriage insert. If spacer plates are now inserted between the housing of the rollers and the bottom of the blind hole, the housings of the rollers may partly protrude from the blind hole, but 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 if the height differences between the individual rollers or roller pairs is only small and therefore the use of a second car use due to its geometric extent is out of the question.
