Definitions

  • the present invention relates to a method and a device for dismantling and/or assembling an annular component which is arranged at a position within a turbine housing which is accessible via an access of the turbine housing.
  • Ring-shaped components of the type mentioned which are designed to be divided and which can be, for example, oil tanks or the like, are currently dismantled or assembled manually, in particular as part of maintenance and repair work.
  • this due to the narrowness within the turbine housing and the high weight of the component, this is very problematic.
  • the personnel can easily injure themselves while handling the component.
  • the handling is associated with a high physical strain.
  • the manual disassembly and assembly takes a lot of time, which leads to undesirably long downtimes of the turbine and correspondingly high costs.
  • the EP 2 610 439 A1 discloses a device for disassembling and/or assembling an annular component that is arranged at a position within a turbine housing that is accessible via an access of the turbine housing, comprising at least two slide rails that are designed to be inserted through the access into the interior of the turbine housing and to be mounted in a longitudinal direction and parallel to each other in the lower turbine housing area, and a carriage insertable through the entrance into the interior of the turbine housing, placeable on the slide rails and longitudinally movable back and forth along them.
  • the present invention provides a device for disassembling and/or assembling an annular component which is arranged at a position within a turbine housing which is accessible via an entrance of the turbine housing, comprising at least two slide rails which are designed for this purpose into the interior of the turbine housing and to be installed in a longitudinal direction and parallel to one another in the lower turbine housing area, and a slide that can be inserted through the access into the interior of the turbine housing, can be placed on the slide rails and can be moved back and forth along them in the longitudinal direction, with a base plate and a component receiving device, viewed in the longitudinal direction, fastened in a front end area of the base plate, which is designed in such a way that the component to be dismantled or assembled can be received and releasably fastened to it, the construction for at least the base plate is matched to the construction of the component receiving device in such a way that the weight of the component received on the component receiving device is balanced with the weight of the base plate as a counterweight in such a way
  • an annular component to be disassembled or assembled can be safely moved and disassembled or assembled within the turbine housing between the assembly position of the component and the entrance of the turbine housing with little physical effort.
  • the positioning of the component receiving device in the front end area of the bottom plate of the carriage is of the effect Advantage that the component receiving device can be easily moved to the assembly position component. Since such a positioning of the component receiving device, especially when a component is held on it, leads to a very unfavorable weight distribution, which can result in the carriage tipping on the slide rails, the construction of the base plate and the component receiving device is coordinated in such a way that the weight of the component picked up on the component pick-up device is balanced with the weight of the base plate as a counterweight. In this way, a tilt-free movement of the carriage on the slide rails is ensured even when a component is received on the component receiving device.
  • the base plate is designed in the form of a ring segment.
  • the shape of the base plate is adapted to the cylindrical shape of the turbine housing interior space defined by the turbine housing.
  • the base plate cannot collide with other turbine components arranged there, such as in particular with the turbine rotor, during its movement through the turbine housing interior.
  • a predetermined front area of the base plate can be moved in the longitudinal direction beyond the front end of the slide rails, with a first sliding surface being provided in this predetermined area on the underside of the base plate.
  • This configuration takes into account a turbine housing design in which the slide rails cannot be guided all the way to the assembly position of the ring-shaped component due to a lack of space due to a turbine housing shoulder protruding radially inwards.
  • the annular segment-shaped sliding surface of the bottom plate of the carriage rests on the turbine housing step and facilitates movement of the carriage up to the assembly position of the component.
  • the component receiving device can be adjusted in height relative to the slide rails in order to enable fine adjustment of the component receiving device in relation to the mounting position of the component or in relation to the component itself.
  • this height adjustability is achieved in that the first sliding surface is formed on a sliding surface element which is accommodated in a recess in the base plate and which can be moved up and down relative to the base plate via an actuating device.
  • a second sliding surface in particular in the form of a segment of a circular ring, is preferably provided in the upper region of the component receiving device opposite the first sliding surface, the radius of which corresponds to that of the first sliding surface.
  • the component receiving device has an annular carrier element which extends upwards from the base plate and on which a plurality of component receiving flanges which project outwards in the longitudinal direction are distributed circumferentially and which define radial outer surfaces which extend in the circumferential direction and are arranged on a common circular arc , whose diameter is slightly smaller than the inner diameter of the component.
  • the ring-shaped design of the carrier element leads to a very stable construction of the component receiving device, which also prevents the component receiving device from being able to collide with other turbine components during the movement of the carriage along the slide rails. During the movement of the carriage along the slide rails, the carrier element is simply pushed over the turbine rotor to the assembly position of the component.
  • the component receiving flanges Upon reaching the component, the component receiving flanges are inserted into the inner diameter of the component, so that the inner peripheral surface of the component rests on the radially outer surfaces.
  • the center point of the circular arc on which the radial outer surfaces are arranged and the center point of the ring-shaped component must be aligned with one another in the longitudinal direction, which may require a corresponding alignment of the component receiving device, which can be done, for example, via the aforementioned height adjustment.
  • An outwardly pointing end face of the carrier element or a component receiving flange preferably defines a stop surface for the component received on the component receiving flanges in order to achieve a repeatable, defined positioning of the component for the subsequent fastening when the component is received on the component receiving flanges.
  • the carrier element and/or the component-receiving flanges is/are provided with longitudinally extending through-holes through which fastening screws which are screwed into threaded holes provided on the component can be inserted.
  • a handle is provided on the base plate and/or on the component receiving device in order to be able to grip the carriage and move it manually along the slide rails.
  • the component can be dismantled from the turbine housing in a simple, safe and physical manner within a comparatively short period of time.
  • the device 1 is used for disassembling and/or assembling an annular component 2 which is arranged at a position within a turbine housing 3 which is accessible via an access 5 of the turbine housing 3 .
  • the ring-shaped component 2 is in this case a so-called oil box with a sealing ring accommodated in a ring-shaped housing, which seals an annular gap between the turbine housing 3 and a turbine rotor 4, as is shown in FIGS Figures 3 to 5 is shown.
  • the component 2 can also be other ring-shaped components that are installed inside the turbine housing.
  • the device 1 comprises as main components two slide rails 6 and a carriage 7 that can be moved on these.
  • the slide rails 6 are designed to be introduced into the interior of the turbine casing 3 through the access 5 and to be mounted in a longitudinal direction L and parallel to one another in the lower region of the turbine casing.
  • the carriage 7 is also designed in such a way that it can be introduced into the interior of the turbine housing 3 through the access 5 and placed on the slide rails 6 in such a way that it can be moved back and forth along them in the longitudinal direction L.
  • the Carriage 7 comprises a base plate 8 and a component receiving device 9 fastened in a front end region of base plate 8 viewed in longitudinal direction L.
  • Base plate 8 is in the form of a ring segment here and is therefore adapted to the cylindrical shape of the turbine housing cavity.
  • the underside of the base plate 8 is provided with stops 10 which bear against the slide rails 6 and limit the movement of the carriage in the circumferential direction. Proceeding from the stops 10 , a sliding surface 12 , which is also in the form of a segment of a circular ring, is provided on the underside of the base plate 8 , which is formed on a sliding surface element 13 accommodated in a recess in the base plate 8 . In the embodiment shown, the sliding surface element 13 can be moved up and down relative to the base plate 8 in the direction of the arrow 15 via an actuating device 14 (not shown in detail) and is therefore adjustable in height.
  • the height adjustment is effected by a user by actuating an adjustment unit 16 provided in the rear area of the base plate 8 by pushing it forwards or backwards in the direction of the arrow 17 .
  • the movement of the adjustment unit 16 is transmitted to a wedge element 30 installed between the base plate 8 and the sliding surface element 13, which wedge element 30 moves the base plate 8 and the sliding surface element 13 towards or away from one another.
  • the component receiving device 9 is fastened in a front end area of the base plate 8 viewed in the longitudinal direction L. It is designed in such a way that the ring-shaped component 2 to be dismantled or assembled can be accommodated on it and releasably fastened in the longitudinal direction L, aligned with the ring gap.
  • the component receiving device 9 has a ring-shaped support element 18 which extends upwards from the base plate 8 .
  • Two component receiving flanges 19 projecting outwards in the longitudinal direction L are provided on the support element 18 at the top and bottom circumferentially opposite one another and define circumferentially extending radial outer surfaces 20 which are arranged on a common circular arc whose diameter is slightly smaller than the inner diameter of component 2.
  • more component-receiving flanges 19 can of course also be distributed circumferentially on the carrier element 18 .
  • the component receiving flanges 19 are positioned in the area of the inner circumference of the carrier element 19 in such a way that the outwardly facing end face 21 of the carrier element 18 and/or the end faces 22 of the component receiving flanges 19 define a stop surface for the component 2 received on the component receiving flanges 19.
  • Through the end faces 22 of the component receiving flanges 19 extend in the longitudinal direction L through holes 23, which are used to hold fastening screws.
  • the through holes 23 are widened behind the end faces 22 so that the fastening screws can be easily inserted with a suitable tool, such as a screw tool or the like.
  • a second sliding surface 24 which in the present case is also in the shape of a segment of a circular ring, the radius of which corresponds to that of the first sliding surface 12 .
  • a handle 25 or 26 is provided on the base plate 8 and on the component receiving device 9 in order to move the carriage 7 manually in the longitudinal direction L on the slide rails 6 .
  • figure 2 shows the carriage 7 in a state in which the component 2 is held and fastened to it.
  • the component receiving flanges 19 engage in the inner circumference of the component 2 in such a way that the inner peripheral surface of the component 2 is received or rests against the outer surfaces 20 of the component receiving flanges 19 .
  • the end face of the component 2 pointing towards the component receiving device 9 bears against the end face 21 of the carrier element 18 .
  • Fastening screws (not shown in detail) are passed through the through holes 23 and are screwed into associated threaded bores (also not shown in detail here) which are formed in the end face of the component 2 . Accordingly, the component 2 is securely fastened to the carriage 7 .
  • the construction of the base plate 8 including the sliding surface element 13 is matched to the construction of the component receiving device 9 and to the dead weight of the component 2 in such a way that the additional weight of the Component receiving device 9 recorded component 2 is balanced with the weight of the base plate 8 and the sliding surface element 13 as a counterweight.
  • the base plate 8 can also be provided with additional counterweights in the rear end area. Overall, this prevents the carriage 7 from tipping over on the slide rails 6 when a component 2 is held on it.
  • a first step S1 the slide rails 6 of the device 1 are inserted through the access 5 of the turbine housing 3 into the interior of the turbine housing 3.
  • access 5 was created by dismantling a turbine housing cover (not shown).
  • the access 5 can also be a manhole provided in the upper area of the turbine housing 3 .
  • the slide rails 6 are mounted at predetermined positions in the lower turbine housing area in such a way that they extend from a position in the area of the access 5 in the longitudinal direction L and parallel to one another in the direction of the component 2 to be dismantled.
  • the slide rails 6 protrude from the turbine housing 3 and are supported on the turbine housing 3 by a support structure 27 .
  • the free ends of the slide rails 6 protruding from the turbine housing 3 are connected to one another via a connecting strut 28, as a result of which the required stability is achieved.
  • stopper elements 29 are provided which point in the direction of the turbine housing 3 and limit the movement of the carriage 7 on the slide rails 6 at the ends.
  • step S3 the carriage is placed on the slide rails 6 using a crane in such a way that the component receiving device 9 points in the direction of the component 2.
  • step S4 the carriage 7 is now moved on the slide rails 6 in the direction of the component 2.
  • the sliding surfaces 12 and 24 of the carriage 7 come into contact with the turbine housing wall in the region of the turbine housing shoulder 11, so that the sliding surfaces 12 and 24 slide on the turbine housing wall.
  • the area of the base plate 8 on which the sliding surface 12 is arranged is moved in the longitudinal direction L beyond the front end of the slide rails 6 .
  • the component receiving flanges 19 of the component receiving device 9 are pushed into the inner diameter of the component 2 so that the component 2 is received on the component receiving device 9 .
  • the component receiving device 9 can be aligned relative to the component 2 in an intermediate step by moving the adjustment unit 16 in the direction of the arrow 17 and thus the sliding surface element 13 relative to the base plate 8 is moved. In this way, there is also a relative movement between the component receiving device 9 and the slide rails 6 in the upward or downward direction, as a result of which the height of the component receiving device 9 is adjusted.
  • the component 2 is then fastened to the component receiving device 9 in step S5 by fastening screws passing through the through-holes 23 of the component receiving device 9 are used and screwed to the component, as has already been described above.
  • step S6 the carriage 7 is moved on the slide rails 6 in the direction of the access 5 until the component is positioned in the area of the access 5, in the present case outside the turbine housing 3, as shown in FIG figure 5 is shown.
  • the component 2 is released from the component receiving device 9 and can then be lifted off the carriage 7 with a crane in a final step S8.
  • a step S9 the component 2 is picked up and fastened on the component receiving device 9 .
  • step S10 the carriage 7 is moved on the slide rails 6 in the direction of the predetermined mounting position of the component 2 until the component 2 is arranged at the predetermined mounting position.
  • an optional alignment of the component receiving device 9 relative to the annular gap can take place in advance, if this should be necessary.
  • the component 2 is now released from the component receiving device 9 in step S11, whereupon the carriage is moved back on the slide rails 6 in the direction of the access 5 in step S12.
  • a significant advantage associated with the use of the device 1 described above in the disassembly and / or assembly of the component 2 is that the component 2 can be moved safely and without much effort inside the turbine housing 3 in the longitudinal direction L. On the one hand, this is beneficial to the safety and health of the staff. On the other hand, however, a shorter period of time is required for the disassembly or assembly of the component 2, as a result of which downtimes of the turbine can be reduced and costs can be saved.
  • the construction of the device 1 is to be fundamentally adapted to the external conditions that are predetermined by the construction of the turbine.
