[0049] This application provides an embodiment of a device for adjusting the assembly position of an exhaust diffuser and a retaining ring. For example... Figure 1-4As shown, in some embodiments, an assembly position adjustment device for the exhaust diffuser 20 and the retaining ring 10 is provided. The exhaust diffuser 20 includes a first set of lifting lugs 201 and a second set of lifting lugs 202, which are symmetrically distributed about the central axis of the exhaust diffuser 20. The retaining ring 10 includes a first notch 101 and a second notch (not shown, but with the same structure as the first notch 101, hereinafter the same), which are symmetrically distributed about the central axis of the retaining ring 10. The device includes a first adjustment component 30, a first adjustment block 40, a second adjustment component 50, and a second adjustment block 60. The first adjustment component 30 and the first set of lifting lugs are also included. The first adjusting block 40 is connected to the first notch 101 of the holding ring 10. The first adjusting component 30 is used to push the first adjusting block 40 to move left and right and forward and backward relative to the exhaust diffuser 20. The second adjusting component 50 is connected to the second set of lifting lugs 202. The second adjusting block 60 is connected to the second notch of the holding ring 10. The second adjusting component 50 is used to push the second adjusting block 60 to move left and right and forward and backward relative to the exhaust diffuser 20. When the first adjusting block 40 and the second adjusting block 60 move, the holding ring 10 moves relative to the exhaust diffuser 20, so that the central axis of the holding ring 10 coincides with the central axis of the exhaust diffuser 20.

[0050] It should be noted that in the embodiments of this application, the first adjustment component 30 and the first adjustment block 40 are arranged symmetrically at 180 degrees, and correspondingly, the second adjustment component 50 and the second adjustment block 60 are arranged symmetrically at 180 degrees. The first adjustment component 30 and the second adjustment component 50 may be identical in structural design, and the first adjustment block 40 and the second adjustment block 60 may be identical in structural design.

[0051] Specifically, such as Figure 1 and 2 As shown, when the gas turbine is assembled, the retaining ring 10 needs to be placed on top of the exhaust diffuser 20. However, due to the assembly gap between the exhaust diffuser 20 and the retaining ring 10 (e.g., ... Figure 2 As shown in the figure, when the retaining ring 10 is placed on the exhaust diffuser 20, the central axes of the two are not in the same position. At this time, it is necessary to adjust the exhaust diffuser and the retaining ring to ensure that the assembly between the two can meet the normal working requirements.

[0052] like Figure 1 and 2As shown, the first set of lifting lugs 201 and the second set of lifting lugs 202 are symmetrically distributed about the central axis of the exhaust diffuser 20, and the first notch 101 and the second notch are symmetrically distributed about the central axis of the retaining ring 10. Based on the structural characteristics of the retaining ring 10 and the exhaust diffuser 20, the inventors of this application have developed an assembly position adjustment device for the exhaust diffuser 20 and the retaining ring 10, used to adjust the central axis of the retaining ring 10 to a position coinciding with the central axis of the exhaust diffuser 20, so that the assembly between the retaining ring 10 and the exhaust diffuser 20 meets the normal working requirements.

[0053] like Figure 1-4 As shown, a first adjustment component 30 and a first adjustment block 40 are respectively connected to the first set of lifting lugs 201 and the second set of lifting lugs 202, and the first adjustment block 40 is inserted into the first notch 101 of the holding ring 10 to push the holding ring 10 to move left and right and forward and backward. In this embodiment, the first adjustment component 30 can be detachably connected to the first set of lifting lugs 201; for example, the first adjustment component 30 can be detachably connected to the first set of lifting lugs 201 by bolts.

[0054] It should be noted that in this embodiment of the application, the first adjustment component 30 is used to push the first adjustment block 40 to move left and right and forward and backward. This means that the first adjustment component 30 is used to push the first adjustment block 40 to move left and right and forward and backward relative to the exhaust diffuser 20. That is, when the first adjustment block 40 moves left and right or forward and backward relative to the exhaust diffuser 20, it drives the holding ring 10 to move left and right and forward and backward relative to the exhaust diffuser 20, thereby adjusting the central axis of the holding ring 10 to a position that coincides with the central axis of the exhaust diffuser 20.

[0055] Accordingly, by providing a second adjustment component 50 and a second adjustment block 60 connected to the second set of lifting lugs 202, and inserting the second adjustment block 60 into the second notch of the retaining ring 10, the second adjustment component 50 is used to push the second adjustment block 60 to move left and right and forward and backward. In this embodiment, the second adjustment component can be detachably connected to the second set of lifting lugs 202; for example, the second adjustment component can be detachably connected to the second set of lifting lugs 202 by bolts.

[0056] It should be noted that, in this embodiment of the application, the second adjustment component 50 is used to push the second adjustment block 60 to move left and right and forward and backward. This means that the second adjustment component 50 is used to push the second adjustment block 60 to move left and right and forward and backward relative to the exhaust diffuser 20. That is, when the second adjustment block 60 moves left and right and forward and backward relative to the exhaust diffuser 20, it drives the holding ring 10 to move left and right and forward and backward relative to the exhaust diffuser 20, thereby adjusting the central axis of the holding ring 10 to a position that coincides with the central axis of the exhaust diffuser 20.

[0057] In this embodiment, moving the holding ring 10 forward and backward relative to the exhaust diffuser 20 means that when the first adjustment component 30 pushes the first adjustment block 40 forward relative to the exhaust diffuser 20, by adjusting the second adjustment component 50 which is symmetrically arranged with the first adjustment component 30, the positions on the holding ring 10 corresponding to the first adjustment component 30 and the second adjustment component 50 can be moved forward or backward simultaneously.

[0058] In this embodiment, since there is an assembly gap between the exhaust diffuser 20 and the retaining ring 10, and the first adjustment assembly 30 and the first adjustment block 40 are arranged symmetrically at 180 degrees, and the second adjustment assembly 50 and the second adjustment block 60 are also arranged symmetrically at 180 degrees, in order to adjust the central axis of the retaining ring 10 to coincide with the central axis of the exhaust diffuser 20, when adjusting the position of the central axis of the retaining ring 10 relative to the central axis of the exhaust diffuser 20 by the first adjustment assembly 30 and the first adjustment block 40, the position of the central axis of the retaining ring 10 relative to the central axis of the exhaust diffuser 20 can be adjusted simultaneously by the second adjustment assembly 50 and the second adjustment block 60, so that the central axis of the retaining ring 10 and the central axis of the exhaust diffuser 20 can coincide.

[0059] Alternatively, in this embodiment of the application, based on the relative position between the central axis of the retaining ring 10 and the central axis of the exhaust diffuser 20, the position of the central axis of the retaining ring 10 relative to the central axis of the exhaust diffuser 20 can be adjusted separately by the first adjusting component 30 and the first adjusting block 40, or the position of the central axis of the retaining ring 10 relative to the central axis of the exhaust diffuser 20 can be adjusted separately by the second adjusting component 50 and the second adjusting block 60, so that the central axis of the retaining ring 10 and the central axis of the exhaust diffuser 20 can coincide.

[0060] In the embodiments of this application, such as Figure 1 As shown, a stationary vane (not shown) is provided on the inner side of the retaining ring 10, and the stationary vane has an inner circle. The exhaust diffuser 20 has an outer circle (not shown). When the position of the central axis of the retaining ring 10 relative to the central axis of the exhaust diffuser 20 is adjusted by the first adjusting component 30 and the first adjusting block 40, and / or the position of the central axis of the retaining ring 10 relative to the central axis of the exhaust diffuser 20 is adjusted by the second adjusting component 50 and the second adjusting block 60, the inner circle of the stationary vane and the outer circle of the exhaust diffuser 20 are in a mutually engaging position. Moreover, when the gap between the inner circle of the stationary vane and the outer circle of the exhaust diffuser 20 is uniform, it indicates that the central axis of the retaining ring 10 and the central axis of the exhaust diffuser 20 are in a coincident position. In this embodiment, a feeler gauge can be inserted into the gap between the inner circle of the stationary vane and the outer circle of the exhaust diffuser 20 to verify whether the gap between the two is uniform.

[0061] In this embodiment, the first adjustment component 30, the first adjustment block 40, the second adjustment component 50, and the second adjustment block 60 can be made of rigid materials; for example, the first adjustment component 30, the first adjustment block 40, the second adjustment component 50, and the second adjustment block 60 can be made of metals such as stainless steel, which can meet the rigidity and strength requirements required for adjusting the position of the holding ring 10 relative to the exhaust diffuser 20.

[0062] This application provides an assembly position adjustment device for an exhaust diffuser 20 and a retaining ring 10. The device comprises a first adjustment component 30, a first adjustment block 40, a second adjustment component 50, and a second adjustment block 60. The first adjustment component 30 is connected to the first set of lifting lugs 201 and 202 symmetrically distributed along the central axis of the exhaust diffuser 20, and a first notch 101 and a second notch symmetrically distributed along the central axis of the retaining ring 10. The first adjustment block 40 is inserted into the first notch 101 of the retaining ring 10. When the first adjustment component 30 is pushed, the first adjustment block 40 can move left and right and forward and backward, thereby effectively moving the retaining ring 10 relative to the exhaust diffuser 20.

[0063] Accordingly, by connecting the second adjustment component 50 to the second set of lifting lugs 202 and inserting the second adjustment block 60 into the second notch of the retaining ring 10, when the second adjustment component 50 is pushed, the second adjustment block 60 can be driven to move left and right and forward and backward, thereby effectively driving the retaining ring 10 to move left and right and forward and backward relative to the exhaust diffuser 20. Overall, the central axes of the retaining ring 10 and the exhaust diffuser 20 can be effectively adjusted to coincident assembly positions.

[0064] like Figure 3 and 4 As shown, in some embodiments, the first adjustment assembly 30 includes a first fixing member 301 and a first adjustment member 302. The first fixing member 301 is connected to the first set of lifting lugs 201, and the first adjustment member 302 passes through the first fixing member 301. The first adjustment member 302 is used to push the first adjustment block 40 to move to the right. For example, when the central axis of the holding ring 10 is offset to the left relative to the central axis of the exhaust diffuser 20, the first adjustment member 302 can push the first adjustment block 40 to move to the right, thereby causing the holding ring 10 to move to the right relative to the exhaust diffuser 20. Overall, the central axes of the holding ring 10 and the exhaust diffuser 20 can be effectively adjusted to coincident assembly positions. In this embodiment, the first fixing member 301 can be detachably connected to the first set of lifting lugs 201; for example, the first fixing member 301 can be detachably connected to the first set of lifting lugs 201 by bolts, which facilitates disassembly.

[0065] In this embodiment, the first adjusting member 302 is used to push the first adjusting block 40 to move to the right. This means that the first adjusting member 302 pushes the first adjusting block 40 to move to the right relative to the exhaust diffuser 20. Specifically, when the first adjusting block 40 moves to the right relative to the exhaust diffuser 20, it causes the retaining ring 10 to move to the right relative to the exhaust diffuser 20, effectively adjusting the central axis of the retaining ring 10 to an assembly position coinciding with the central axis of the exhaust diffuser 20. The first adjusting member 302 can be a bolt. The first adjusting member 302 can be screwed to the first fixing member 301.

[0066] like Figure 3 and 4 As shown, in some embodiments, the first adjusting assembly 30 further includes a second adjusting member 303, which passes through the first fixing member 301. The second adjusting member 303 is used to push the first adjusting block 40 to move to the left. For example, when the central axis of the retaining ring 10 is offset to the right relative to the central axis of the exhaust diffuser 20, the second adjusting member 303 can push the first adjusting block 40 to move to the left, thereby causing the retaining ring 10 to move to the left relative to the exhaust diffuser 20. Overall, this can effectively adjust the central axes of the retaining ring 10 and the exhaust diffuser 20 to coincide. The second adjusting member 303 can be a bolt. The second adjusting member 303 can be screwed to the first fixing member 301.

[0067] In this embodiment of the application, the second adjusting member 303 is used to push the first adjusting block 40 to move to the left. This means that the second adjusting member 303 is used to push the first adjusting block 40 to move to the left relative to the exhaust diffuser 20. That is, when the first adjusting block 40 moves to the left relative to the exhaust diffuser 20, it drives the holding ring 10 to move to the left relative to the exhaust diffuser 20, which can adjust the central axis of the holding ring 10 to the assembly position that coincides with the central axis of the exhaust diffuser 20.

[0068] like Figure 3 and 4 As shown, in some embodiments, the first adjusting assembly 30 further includes a third adjusting member 304, which passes through the first fixing member 301. The third adjusting member 304 is used to push the first adjusting block 40 to move forward and backward. For example, when the central axis of the retaining ring 10 is offset forward relative to the central axis of the exhaust diffuser 20, the third adjusting member 304 can push the first adjusting block 40 to move backward, thereby causing the retaining ring 10 to move backward relative to the exhaust diffuser 20. Overall, this can effectively adjust the central axes of the retaining ring 10 and the exhaust diffuser 20 to coincide in the assembly position. The third adjusting member 304 can be a bolt. The third adjusting member 304 can be screwed to the first fixing member 301.

[0069] In this embodiment, the third adjusting member 304 is used to push the first adjusting block 40 to move forward and backward. This means that the third adjusting member 304 is used to push the first adjusting block 40 to move forward or backward relative to the exhaust diffuser 20. That is, when the first adjusting block 40 moves forward or backward relative to the exhaust diffuser 20, it drives the holding ring 10 to move forward or backward relative to the exhaust diffuser 20, which can adjust the central axis of the holding ring 10 to the assembly position that coincides with the central axis of the exhaust diffuser 20.

[0070] like Figure 3 and 4 As shown, in some embodiments, the first fixing member 301 further includes a first left fixing plate 3011, a first right fixing plate 3012 and a first bolt 3013. The first left fixing plate 3011 and the first right fixing plate 3012 are fixed to the first set of lifting lugs 201 by the first bolt 3013 to facilitate disassembly and installation.

[0071] like Figure 3 and 4 As shown, in some embodiments, the first fixing member 301 further includes a first front fixing plate 3014, which is connected to the first left fixing plate 3011 and the first right fixing plate 3012. The third adjusting member 304 passes through the first front fixing plate 3014, facilitating disassembly and installation. In this embodiment, for ease of adjustment and observation, the upper width of the first front fixing plate 3014 can be designed to be smaller than its lower width.

[0072] Furthermore, the upper width of the first front fixing plate 3014 is designed to be smaller than the width of the first adjusting block 40, which is more conducive to adjustment and observation. In this embodiment, the first fixing member 301 also includes a plurality of third bolts 3015. The first front fixing plate 3014 is detachably connected to the first left fixing plate 3011 and the first right fixing plate 3012 respectively by the plurality of third bolts 3015, which facilitates the disassembly and installation of the first front fixing plate 3014.

[0073] like Figure 4 As shown, in order to smoothly insert the first adjusting block 40 into the notch 101 of the retaining ring 10, a protrusion 401 is provided on the side of the first adjusting block 40 facing the first notch 101 of the retaining ring 10. The protrusion 401 can be rectangular in shape, and the upper and lower edges of the front end of the rectangular protrusion 401 are designed with arc transitions, which makes it easier for the protrusion 401 to be inserted into the first notch 101. Moreover, in order to facilitate the disassembly of the first adjusting block 40, a screw hole 402 is provided on the side of the first adjusting block 40 opposite to the first front fixing plate 3014. The entire first adjusting block 40 can be easily disassembled by the cooperation of the puller and the screw hole 402.

[0074] like Figure 4As shown, the first fixing member 301 further includes a first left adjusting plate 305 and a first right adjusting plate 306. The first left adjusting plate 305 is detachably connected to the first left fixing plate 3011 by bolts for easy disassembly and installation. The first right adjusting plate 306 is detachably connected to the first right fixing plate 3012 by bolts for easy disassembly and installation. The first adjusting member 302 is detachably connected to the first left adjusting plate 305 by bolts for easy disassembly and installation. The second adjusting member 303 is detachably connected to the first right adjusting plate 306 by bolts for easy disassembly and installation.

[0075] like Figure 5 and 6 As shown, in some embodiments, the second adjustment assembly 50 includes a second fixing member 501 and a fourth adjustment member 502. The second fixing member 501 is connected to the second set of lifting lugs 202, and the fourth adjustment member 502 passes through the second fixing member 501. The fourth adjustment member 502 is used to push the second adjustment block 60 to move to the right. For example, when the central axis of the holding ring 10 is offset to the left relative to the central axis of the exhaust diffuser 20, the fourth adjustment member 502 can push the second adjustment block 60 to move to the right, thereby causing the holding ring 10 to move to the right relative to the exhaust diffuser 20, which can effectively adjust the central axis of the holding ring 10 to a position coinciding with the central axis of the exhaust diffuser 20. The fourth adjustment member 502 can be a bolt. The fourth adjustment member 502 can be screwed to the second fixing member 501. In the embodiments of this application, the second fixing member 501 can be detachably connected to the second set of lifting lugs 202; for example, the second fixing member 501 can be detachably connected to the second set of lifting lugs 202 by bolts, which facilitates disassembly.

[0076] In this embodiment, the fourth adjusting member 502 is used to push the second adjusting block 60 to move to the right. This means that the fourth adjusting member 502 is used to push the second adjusting block 60 to move to the right relative to the exhaust diffuser 20. That is, when the second adjusting block 60 moves to the right relative to the exhaust diffuser 20, it drives the holding ring 10 to move to the right relative to the exhaust diffuser 20, which can effectively adjust the central axis of the holding ring 10 to the position of coinciding with the central axis of the exhaust diffuser 20.

[0077] like Figure 5 and 6As shown, in some embodiments, the second adjusting assembly 50 further includes a fifth adjusting member 503, which passes through the second fixing member 501. The fifth adjusting member 503 is used to push the second adjusting block 60 to move to the left. For example, when the central axis of the retaining ring 10 is offset to the right relative to the central axis of the exhaust diffuser 20, the fifth adjusting member 503 can push the second adjusting block 60 to move to the left, thereby causing the retaining ring 10 to move to the left relative to the exhaust diffuser 20, effectively adjusting the central axes of the retaining ring 10 and the exhaust diffuser 20 to coincide. The fifth adjusting member 503 can be a bolt. The fifth adjusting member 503 can be screwed to the second fixing member 501.

[0078] In this embodiment of the application, the fifth adjusting member 503 is used to push the second adjusting block 60 to move to the left. This means that the fifth adjusting member 503 is used to push the second adjusting block 60 to move to the left relative to the exhaust diffuser 20. That is, when the second adjusting block 60 moves to the left relative to the exhaust diffuser 20, it drives the holding ring 10 to move to the left relative to the exhaust diffuser 20, which can adjust the central axis of the holding ring 10 to coincide with the central axis of the exhaust diffuser 20.

[0079] like Figure 5 and 6 As shown, in some embodiments, the second adjustment assembly 50 further includes a sixth adjustment member 504, which passes through the second fixing member 501. The sixth adjustment member 504 is used to push the second adjustment block 60 to move forward and backward. For example, when the central axis of the retaining ring 10 is offset forward relative to the central axis of the exhaust diffuser 20, the sixth adjustment member 504 can push the second adjustment block 60 to move backward, thereby causing the retaining ring 10 to move backward relative to the exhaust diffuser 20, effectively adjusting the central axes of the retaining ring 10 and the exhaust diffuser 20 to coincide. The sixth adjustment member 504 can be a bolt. The sixth adjustment member 504 can be screwed to the second fixing member 501.

[0080] In this embodiment, the sixth adjusting member 504 is used to push the second adjusting block 60 to move forward and backward. This means that the sixth adjusting member 504 is used to push the second adjusting block 60 to move forward or backward relative to the exhaust diffuser 20. That is, when the second adjusting block 60 moves forward or backward relative to the exhaust diffuser 20, it drives the holding ring 10 to move forward or backward relative to the exhaust diffuser 20, which can adjust the central axis of the holding ring 10 to coincide with the central axis of the exhaust diffuser 20.

[0081] In this embodiment, when the third adjusting member 304 pushes the holding ring 10 forward relative to the exhaust diffuser 20, correspondingly, by adjusting the sixth adjusting member 504 symmetrically arranged with the third adjusting member 304, the positions on the holding ring 10 corresponding to the third adjusting member 304 and the sixth adjusting member 504 can be moved forward or backward simultaneously; or, when the sixth adjusting member 504 pushes the holding ring 10 forward relative to the exhaust diffuser 20, correspondingly, by adjusting the third adjusting member 304 symmetrically arranged with the sixth adjusting member 504, the positions on the holding ring 10 corresponding to the third adjusting member 304 and the sixth adjusting member 504 can be moved forward or backward simultaneously.

[0082] like Figure 5 and 6 As shown, in some embodiments, the second fixing member 501 includes a second left fixing plate 5011, a second right fixing plate 5012, and a second bolt 5013. The second left fixing plate 5011 and the second right fixing plate 5012 are fixed to the second set of lifting lugs 202 by the second bolt 5013, which facilitates disassembly and installation.

[0083] like Figure 5 and 6 As shown, in some embodiments, the second fixing member 501 further includes a second front fixing plate 5014, which is connected to the second left fixing plate 5011 and the second right fixing plate 5012. The sixth adjusting member 504 passes through the second front fixing plate 5014, facilitating disassembly and installation. In this embodiment, to facilitate adjustment and observation, the upper width of the second front fixing plate 5014 can be designed to be smaller than its lower width; furthermore, designing the upper width of the second front fixing plate 5014 to be smaller than the width of the second adjusting block 60 is even more conducive to adjustment and observation.

[0084] In this embodiment of the application, the second fixing member 501 further includes a plurality of fourth bolts 5015. The second front fixing plate 5014 is detachably connected to the second left fixing plate 5011 and the second right fixing plate 5012 respectively by the plurality of fourth bolts 5015, which facilitates the disassembly and installation of the second front fixing plate 5014.

[0085] like Figure 6 As shown, the second fixing member 501 also includes a second left adjusting plate 505 and a second right adjusting plate 506. The second left adjusting plate 505 is detachably connected to the second left fixing plate 5011 by bolts for easy disassembly and installation. The second right adjusting plate 506 is detachably connected to the second right fixing plate 5012 by bolts for easy disassembly and installation. The fourth adjusting member 502 is detachably connected to the second left adjusting plate 505 by bolts for easy disassembly and installation. The fifth adjusting member 503 is detachably connected to the second right adjusting plate 506 by bolts for easy disassembly and installation.
