Description

Technical Field

[0001] This application belongs to the field of aero-derivative gas turbine installation, and specifically relates to an X-type aero-derivative gas turbine support structure and its usage method. Background Technology

[0002] Conventional aero-derivative gas turbines are typically used in confined environments such as container houses or ship cabins. After prolonged operation, wear and slight deformation of the gas turbine components may cause the gas turbine's attitude to deviate, resulting in the gas turbine's rotation center not being concentric with the load's rotation center. This leads to increased gas turbine vibration, abnormal wear of structural components, reduced gas turbine life, and also affects operational safety.

[0003] Conventional aero-derivative gas turbine support systems typically have 4-6 support legs. Adjusting the gas turbine's attitude usually involves using shims, adjusting the height of some or all of the shims on the support legs. Since the shims are installed between the support legs and the underframe, replacing them requires lifting the gas turbine. When the gas turbine is installed in a confined environment such as a container house or ship cabin, due to environmental constraints, large lifting equipment can generally only be used after the container house's top cover is opened or the ship cabin's upper deck is cut, resulting in high adjustment costs and complex procedures. Because existing technical solutions involve complex structural adjustment procedures, long operation times, and high economic costs, they often delay the adjustment of the gas turbine's attitude.

[0004] Therefore, it is necessary to design a support structure that can be used in confined environments and adjust the attitude of the gas turbine without lifting it.

[0005] Therefore, there is an urgent need for a technical solution to overcome or mitigate at least one of the aforementioned defects in the existing technology. Summary of the Invention

[0006] The purpose of this application is to provide a support structure for an X-type aero-derivative gas turbine and its usage method, in order to solve at least one problem existing in the prior art.

[0007] The technical solution of this application is:

[0008] The first aspect of this application provides an X-type aero-derivative gas turbine support structure, disposed between the gas turbine support legs and the base frame, comprising:

[0009] The support body main body includes an upper panel, a lower panel, a deformable longitudinal connecting plate, a transverse connecting plate, and a clamping block, wherein...

[0010] The upper panel is connected to the gas turbine support leg;

[0011] The lower panel is connected to the base frame;

[0012] The deformable longitudinal connecting plate includes two plates, and the two ends of the deformable longitudinal connecting plate are respectively connected to the upper panel and the lower panel. The two deformable longitudinal connecting plates form an X-shaped structure, and mounting holes are provided on the deformable longitudinal connecting plates.

[0013] The transverse connecting plate includes two, and the two transverse connecting plates are respectively connected to the middle of the corresponding deformable longitudinal connecting plate. The transverse connecting plate is provided with mounting holes.

[0014] The clamping block includes two blocks, and the two clamping blocks are respectively connected to the end of the corresponding transverse connecting plate away from the deformable longitudinal connecting plate. The clamping block is provided with mounting holes.

[0015] A screw, which is inserted into the mounting holes of the clamping block, the transverse connecting plate, and the deformable longitudinal connecting plate;

[0016] The fixing nuts are installed in two sets on each screw, with each set consisting of two nuts, and the two fixing nuts are respectively located on both sides of the corresponding clamping block.

[0017] In one embodiment of this application, the upper panel, the lower panel, the deformable longitudinal connecting plate, the transverse connecting plate, and the clamping block are integrally formed.

[0018] In one embodiment of this application, the deformable longitudinal connecting plate is made of an elastic metal material, and its deformation is elastic.

[0019] In one embodiment of this application, the stiffness of the clamping block is higher than the stiffness of the deformable longitudinal connecting plate.

[0020] In one embodiment of this application, a plurality of screws are mounted on each of the support bodies.

[0021] The second aspect of this application provides a method for using an X-type aero-derivative gas turbine support structure, based on the X-type aero-derivative gas turbine support structure described above, comprising:

[0022] Step 1: Install multiple X-type aero-derivative gas turbine support structures between the gas turbine support legs and the base frame;

[0023] Step 2: Measure the misalignment between the rotation center of the gas turbine and the rotation center of the load;

[0024] Step 3: Adjust the corresponding X-type aero-derivative gas turbine support structure according to the misalignment between the gas turbine rotation center and the load rotation center.

[0025] In one embodiment of this application, step three involves adjusting the X-type aero-derivative gas turbine support structure as follows:

[0026] Loosen the fixing nut on the outside of any clamping block and tighten the fixing nut on the inside of the clamping block. The distance between the two clamping blocks increases, which in turn increases the distance between the upper panel and the lower panel, thereby ensuring that the height of the X-type aero-derivative gas turbine support structure reaches the first set height.

[0027] In one embodiment of this application, step three involves adjusting the X-type aero-derivative gas turbine support structure as follows:

[0028] Loosen the fixing nut on the inside of any clamping block and tighten the fixing nut on the outside of the clamping block. The distance between the two clamping blocks decreases, which in turn decreases the distance between the upper panel and the lower panel, thereby ensuring that the height of the X-type aero-derivative gas turbine support structure reaches the second set height.

[0029] The invention has at least the following beneficial technical effects:

[0030] The X-type aero-derivative gas turbine support structure of this application can easily and quickly change the height of the gas turbine support legs to adjust the gas turbine attitude without lifting the gas turbine. Attached Figure Description

[0038] The following is in conjunction with the appendix Figures 1 to 3 This application will be described in further detail.

[0039] The first aspect of this application provides a support structure for an X-type aero-derivative gas turbine, including: a support body 1, a screw 2, and a fixing nut 3.

[0040] like Figure 1 As shown, the main body 1 of the support includes an upper panel 11, a lower panel 12, deformable longitudinal connecting plates 13, transverse connecting plates 14, and clamping blocks 15. The upper panel 11 and lower panel 12 are arranged parallel to each other. The upper panel 11 has connecting holes for connection to the gas turbine support legs via fasteners. The lower panel 12 has connecting holes for connection to the base frame via fasteners. Each main body 1 of the support includes two deformable longitudinal connecting plates 13, with both ends connected to the upper panel 11 and the lower panel 12 respectively, forming an X-shaped structure. The deformable longitudinal connecting plates 13 have mounting holes. Two transverse connecting plates 14 are included, each connected to the middle of its corresponding deformable longitudinal connecting plate 13. The transverse connecting plates 14 also have mounting holes. Two clamping blocks 15 are included, each connected to the end of its corresponding transverse connecting plate 14 away from the deformable longitudinal connecting plate 13. The clamping blocks 15 have mounting holes.

[0041] The screw 2 is inserted into the mounting holes of the clamping block 15, the transverse connecting plate 14, and the deformable longitudinal connecting plate 13; two sets of fixing nuts 3 are installed on each screw 2, each set including two nuts, and the two fixing nuts 3 are located on both sides of the corresponding clamping block 15.

[0042] The X-type aero-derivative gas turbine support structure of this application is an intermediate structural component connecting the gas turbine support legs and the base frame. The upper panel 11 is used to connect the gas turbine support legs, and the lower panel 12 is used to connect the base frame. The clamping block 15 is a rigid metal solid with threaded holes, which is connected to the deformable longitudinal connecting plate 13 via a transverse connecting plate 14. The connection position is at the structural corner of the deformable longitudinal connecting plate 13. The screw 2 is a fully threaded screw, and the fixing nut 3 is a conventional standard nut.

[0043] like Figure 2-3 As shown, in a preferred embodiment of this application, the upper panel 11, lower panel 12, deformable longitudinal connecting plate 13, transverse connecting plate 14, and clamping block 15 are integrally formed. The deformable longitudinal connecting plate 13 is made of elastic metal material, and its deformation is elastic. The stiffness of the clamping block 15 is higher than that of the deformable longitudinal connecting plate 13. It is understood that multiple screws 2 can be installed on each support body 1.

[0044] Based on the aforementioned X-type aero-derivative gas turbine support structure, a second aspect of this application provides a method for using the X-type aero-derivative gas turbine support structure, including:

[0045] Step 1: Install multiple X-type aero-derivative gas turbine support structures between the gas turbine support legs and the base frame;

[0046] Step 2: Measure the misalignment between the rotation center of the gas turbine and the rotation center of the load;

[0047] Step 3: Adjust the corresponding X-type aero-derivative gas turbine support structure according to the degree of misalignment between the gas turbine rotation center and the load rotation center.

[0048] The method of using the X-type aero-derivative gas turbine support structure of this application involves installing the assembled X-type aero-derivative gas turbine support structure at the designed position between the gas turbine support leg and the base frame, and adjusting the X-type aero-derivative gas turbine support structure according to the measured misalignment between the gas turbine rotation center and the load rotation center.

[0049] In one embodiment of this application, when it is necessary to increase the height of the X-type aero-derivative gas turbine support structure, loosen the fixing nut 3 on the outer side of any clamping block 15 and tighten the fixing nut 3 on the inner side of the clamping block 15. The distance between the two clamping blocks 15 increases, thereby increasing the distance between the upper panel 11 and the lower panel 12, thus ensuring that the height of the X-type aero-derivative gas turbine support structure reaches the first set height.

[0050] For the fixing nuts 3 on both sides of a clamping block 15, the height of the X-type aero-derivative gas turbine support structure can be adjusted by repeatedly loosening the outer fixing nut 3 and tightening the inner fixing nut 3. Finally, check that all fixing nuts 3 are tightened to fix the dimensions of the X-type aero-derivative gas turbine support structure.

[0051] In one embodiment of this application, when it is necessary to lower the height of the X-type aero-derivative gas turbine support structure, loosen the fixing nut 3 on the inner side of any clamping block 15 and tighten the fixing nut 3 on the outer side of the clamping block 15. The distance between the two clamping blocks 15 is reduced, thereby reducing the distance between the upper panel 11 and the lower panel 12, thus ensuring that the height of the X-type aero-derivative gas turbine support structure reaches the second set height.

[0052] For the fixing nuts 3 on both sides of a clamping block 15, the height of the X-type aero-derivative gas turbine support structure can be lowered by repeatedly loosening the inner fixing nut 3 and tightening the outer fixing nut 3. Finally, check that all fixing nuts 3 are tightened to fix the dimensions of the X-type aero-derivative gas turbine support structure.

[0053] During the operation of the gas turbine, the misalignment between the rotation center of the gas turbine and the rotation center of the load worsens. The above-mentioned method is used to adjust the support structure of the X-type aero-derivative gas turbine, adjust the attitude of the gas turbine, and ensure the concentricity between the rotation center of the gas turbine and the rotation center of the load.

[0054] The method of using the X-type aero-derivative gas turbine support structure of this application can adjust the attitude of the gas turbine without the need for large lifting equipment. Especially when the gas turbine is installed in a confined environment such as a container or ship cabin, the attitude of the gas turbine can be adjusted without opening the top cover of the container or cutting the upper deck of the ship cabin. The process is simple, the adjustment is quick, and the safety is high. It reduces the downtime of the gas turbine and can significantly improve economic efficiency.

[0055] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
