Description

2024PF01005 1 Description TITLE Housing support for mounting a gas turbine exhaust housing TECHNICAL AREA

[0001] The invention relates to a support device for a housing. The aim is to reliably hold the housing at a predetermined height. BACKGROUND

[0002] Gas turbine exhaust casings, especially those of large gas turbines, are very heavy. This necessitates appropriate support, which in turn is also heavy. Although slight misalignments between the gas turbine exhaust casing and the turbine can be compensated for using leveling elements, permissible limits for this misalignment must not be exceeded. This is particularly important to prevent uncontrolled exhaust gas leakage from the gas turbine.

[0003] Since the exhaust system has no further significance, the costs for its support must be kept low, and therefore only the bare minimum of necessary support elements should be provided. Support is typically achieved using grid-like frames formed from vertical steel posts and crossbeams. Load straps are used to grip the gas turbine exhaust casing that needs to be supported.

[0004] The height is easily adjusted by shortening or lengthening the load straps. This is both a particularly cost-effective and very easy-to-use solution. In particular, attaching the load straps requires no additional equipment, as they are of a manageable weight. 2024PF01005 2

[0005] However, it has proven disadvantageous that, depending on the setting and condition of the load belts, the long-term correct storage of the gas turbine exhaust housing is not always guaranteed. SUMMARY OF THE INVENTION

[0006] The object of the present invention is to enable a cost-effective and simple storage of a heavy gas turbine exhaust housing, which reliably ensures the correct position of the exhaust housing over a longer period of time.

[0007] The problem is solved by an embodiment according to the invention as described in claim 1. Advantageous embodiments are the subject of the dependent claims.

[0008] A housing support serves to mount a housing. The housing support has a grid-like shape and comprises at least two posts arranged perpendicularly to both sides of the housing to be mounted, as well as at least one crossbar to connect the posts.

[0009] The housing is supported by a support element that extends between two posts. This support element is attached at both ends to a post head, and a lifting device located at the post head allows the support element to be raised.

[0010] According to the invention, it is initially provided that the support element is formed by a rigid bracket carrier.

[0011] Essentially, the lifting device comprises a support element which is attached to the post head and on which the bracket rests, and a lifting piston which is arranged between the support element and the post head. 2024PF01005 3 DESCRIPTION OF THE INVENTION

[0012] A housing support of this type serves to mount a housing. The specific type of housing is initially irrelevant. The housing support is particularly suitable for supporting large, heavy components that need to be stored at a predetermined height. In this preferred application, the housing is therefore a gas turbine exhaust housing.

[0013] The housing support has a grid-like shape and comprises at least two posts arranged perpendicularly on both sides opposite the housing to be supported, as well as at least one crossbar to connect the posts.

[0014] In an advantageous embodiment, at least four vertical posts are present, arranged in pairs opposite each other. The four posts are connected by cross braces running transversely to the housing and by cross braces connecting adjacent posts along their length.

[0015] The housing is supported by a support element that extends between two posts. This support element is attached at both ends to a post head, and a lifting device located at the post head allows the support element to be raised.

[0016] If four posts are available, preferably two adjacent support elements are used, each being arranged between two opposing posts.

[0017] The lifting device is not intended to lift the housing from a transport position to its final position. Rather, the lifting device serves to adjust the housing's precise height within the required accuracy. Possible tolerances must be taken into account. 2024PF01005 4

[0018] To avoid or at least reduce changes in position over a longer period of time, in particular a sinking, the invention provides that the support element is formed by a rigid bracket carrier.

[0019] The design as a rigid bracket leads to a disadvantage regarding the weight of the bracket, which - depending on the size - can no longer be handled without aids, but ensures the reliability of the support device in its function as a support for the housing at a fixed height.

[0020] Essential for the successful setup and storage of the housing is that, according to the invention, the lifting device comprises a support element and a lifting piston.

[0021] The support element is attached to the post head when the housing is mounted. The bracket support, in turn, rests on the support element. Therefore, the support for the housing is provided by the housing itself, via the bracket support, to the support element, and then via the post head and the post.

[0022] The lifting piston is provided for height adjustment. It is positioned between the post head and the support element. Thus, to adjust the housing to the intended height, the lifting piston raises the support element, and once the correct position is reached, the support element is then attached to the post head. Although the solution according to the invention has increased the assembly effort, it now ensures that the position of the housing can be maintained over a long period of time.

[0024] Although adjusting the height using pistons allows for easy adjustment, precise adjustment is time-consuming because a piston – especially a hydraulic piston – cannot be positioned exactly without careful consideration. Therefore, for optimization, it is advantageous to use adjustment devices that are height-adjustable or... The 2024PF01005 5 adjustment devices are selectable and can be inserted between the support element and the post head. Using these devices allows the housing to be raised slightly beyond the target position without requiring precise measurements. The adjustment devices can then be inserted or adjusted. When the housing is lowered, the height is determined by the adjustment devices. This allows the exact position to be achieved quickly.

[0026] In one variant, washers are used as adjusting devices, which should be available in different thicknesses.

[0027] In a second preferred variant, adjusting screws are used as the adjustment means. These can be screwed into the support element and are supported at the post head. Thus, by simply turning the adjusting screw, the height of the support element, and therefore of the housing, can be changed relative to the post head.

[0028] To ensure even contact between the support element and the post head without an additional bending moment, it is advantageous to use two opposing adjusting screws – the same applies to other adjusting devices. This allows the piston to be positioned centrally. Once the exact position is achieved, the support element is particularly advantageously secured to the post head using fastening screws. Besides preventing any residual movement, this also prevents the adjusting devices, i.e., preferably the adjusting screws, from being permanently subjected to the full weight. The shape of the support element is initially irrelevant, provided it is attached to the post head and a piston can be positioned between the support element and the post head. 2024PF01005 6 Preferably, the support element has a top support and two opposing mounting plates. The support and mounting plates can be manufactured as a single piece (cast component), a welded construction, or in multiple parts. In any case, the bracket rests on the support, which is braced by the two mounting plates, and the mounting plates are in turn attached to the post head.

[0032] The piston can preferably act directly on the support.

[0033] The adjustment devices can be positioned between the support and the post head. In particular, the use of adjustment screws is simplified when these are located on the mounting plates.

[0034] Although the bracket is designed as an inherently rigid structure, the considerable weight of a resting housing can induce a transverse force in the support element. This, in addition to the forces that must be supported vertically, naturally leads to an additional load at the connection between the support element and the post head. Therefore, to absorb transverse forces and to guide the support element on the post head, particularly during assembly and adjustment, it is especially advantageous to have support elements for guiding and supporting the support element in a transverse direction, i.e., in a direction towards the support element opposite the housing. The initial design of these support elements is irrelevant. In a first advantageous embodiment, the post head has two opposing guide surfaces extending parallel and vertically. These can, for example, be implemented by a vertical groove.It is also possible to provide external guide surfaces in the area of ​​attachment to the post head. Complementing this, sliding surfaces must be provided on the support element in this case, which rest against the guide surfaces. 2024PF01005 7. A small amount of play, which ensures assembly and adjustability, i.e., vertical adjustability, must be taken into account. In a second advantageous variant, two opposing guide plates are arranged on the support element, with the post head located between the guide plates. One guide plate is positioned on the side facing the bracket support, and the other on the opposite side. It is particularly advantageous if the guide plates are not integrally formed with the support element, but at least one of the two guide plates can be removed. This solution allows for easier assembly of the support element on the post head by removing at least one guide plate.

[0039] The design of the bracket is initially irrelevant, provided that a certain inherent rigidity and the load-bearing capacity for the weight of the housing are ensured.

[0040] Preferably, the bracket supports two vertically oriented support struts arranged parallel to each other, and at least one support plate attached to them. The support struts must extend to, or into, a support head, with the support head resting against the supporting element. This allows the weight of the housing to be transferred via the support struts and the support head to the supporting element. For example, the support struts can be made of flat steel cut by laser cutting. In contrast, the design of the support plate is of secondary importance. At a minimum, it serves both to connect the two support struts and as a base for the housing. Preferably, a bent flat steel bar is used for this purpose.

[0042] Although the bracket can be made in one piece, it is particularly advantageous in the case of high weight, which prevents handling without aids, if the bracket is preferably made in two parts and 2024PF01005 8 insofar as it comprises two support segments. In this case, it is provided that the two support segments have a coupling plate at their adjacent ends, whereby both coupling plates can be firmly connected to each other, for example by screwing.

[0043] Dividing the structure into two support segments may also necessitate the use of additional assembly aids. In such cases, it is advantageous to employ an auxiliary device positioned centrally between the posts beneath the bracket. This device can, for example, be mounted on a crossbeam. Ideally, the auxiliary device should include at least one, and preferably two, lifting pistons that allow the support segments, including the coupling plates, to be lifted so that they can be connected after lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] FIG 1 shows an exemplary embodiment for a housing support 01 with two bracket supports 04, each of which rests on two posts 02.

[0045] FIG 2 shows the embodiment from FIG. 1 with an exemplary housing 31 .

[0046] FIG 3 shows in perspective the lifting device 11 with the support element 14 on the post head 12.

[0047] FIG 4 also shows the lifting device 11 in a side view.

[0048] FIG 5 shows a support segment 05a as part of the stirrup support 04.

[0049] FIG 6 shows the auxiliary device 21 under the support segments 05a. DESCRIPTION OF THE EXECUTION FORMS

[0050] Figure 1 shows an exemplary embodiment of a housing support in a perspective view. The grid-like structure with four posts 02, which are connected to each other by crossbars 03, is visible. A bracket 04 is located between each pair of opposing posts. 2024PF01005 9, in this example, consists of two support segments 05a and 05b. The bracket supports 04 are mounted at opposite ends on lifting devices 11 on the posts 02.

[0051] The arrangement of auxiliary devices 21 on each crossbeam 03 below the stirrup supports 04 can also be seen. Figure 2, in addition to Figure 1, shows an exemplary housing support 01 with a housing 31 mounted on it. For example, this could be a gas turbine exhaust housing. Figure 3 shows the lifting device 11 to the housing carrier from Fig. 1 in perspective.

[0054] Figure 4 shows the lifting device 11 in a side view.

[0055] The post head 12, on which the support element 14 is mounted, is partially visible. The bracket support 04, i.e., a support segment 05a with its support head 06, is mounted on the support element 14. The support element 14 has a bearing 16 on its upper side, which forms the connection to the mounting plates 15 arranged on both sides. A lifting piston 13 is arranged centrally between the post head 12 and the bearing 15, by means of which the support element 14, and thus the bracket support 04 and a housing 31 mounted on it, can be raised. The two mounting plates 15 rest against the side of the post head 12 and are fastened in a fixed position by means of fastening screws 18.

[0058] Also visible is the arrangement of two opposing adjusting screws 19, each mounted on a screw-on plate and supported on the post head 12. Guide plates 17 are mounted on the side of the support segment 05a and on the opposite side, and are supported by the screw-on plates 15. 2024PF01005 10. The guide plates 17 also rest on the post head 12, without being directly screwed to it. In particular, the guide plates 17 secure the position in a transverse direction and thus prevent an additional shear force on the screw connection of the mounting plates 15 to the post head 12. To precisely adjust the height of a resting housing 31, the support element 14 can be raised by means of the lifting piston with the fastening screws 18 loosened. When the height is reached, or the support element 14 is slightly above the planned height, the adjusting screws 19 can be screwed onto the post head 12, or at a distance if the support device 14 is above the intended position. After lowering the lifting piston 13, the desired height can be achieved immediately.It is also possible to adjust the pressure in the piston so that the force is not quite sufficient to lift the support element, but the small shortfall can be compensated for by the adjusting screws 19. In this way, the intended height for the supported housing 31 can be reached immediately without much effort. Figure 5 shows an exemplary embodiment of a support segment 05a as part of a stirrup support 04. The structure consists of two parallel support struts 07, made of flat steel, extending vertically along the housing to be supported. A support bearing 08 is inserted between the support struts 07 and the housing to be supported. This bearing 08 connects the two support struts 07 and also forms the base. This bearing 08 can also be made from flat steel by bending. At the upper end is the support head 06, which is mounted on the bearing 16 of the support element 14. At the opposite end is a coupling plate 09, the opposing coupling plates 09 being screwed together to form the stirrup support 04. 2024PF01005 11

[0064] Figure 6 illustrates an auxiliary device 21, which is arranged centrally under the bracket support at the joint of the two coupling plates 09. In this example, the auxiliary device comprises two pistons 22, which are designed to lift the support segments 05a, 05b at their ends before they are screwed to the coupling plates 09, in order to connect them together.
