Description
Technical Field
[0001] This utility model relates to the field of gas turbine assembly technology, specifically a novel elevation adjustment component for gas turbine units. Background Technology
[0002] When a gas turbine is installed on site, its rotor usually needs to be connected to the rotors of other equipment (such as gearboxes, generators, etc.) to drive the operation of the relevant equipment.
[0003] To safely and reliably connect the gas turbine to other rotors, the elevation of the gas turbine unit must be adjusted to align its center with the centers of the other rotors, while ensuring that the rotor flange opening is within the design range. Current technology involves lifting the entire unit to a designated height using a crane or overhead crane, then adding or removing shims at the bottom. This method requires large cranes and multiple personnel to coordinate the operation; the unit weighs tens or even hundreds of tons, and lifting it as a whole poses safety risks. To address the aforementioned issues, Chinese patent literature discloses "A Gas Turbine Unit Elevation Adjustment Component" (Publication No. CN116498402A, Publication Date July 28, 2023). This technology discloses a gas turbine unit elevation adjustment component, including a gas turbine bracket, a unit support, a movable block, and a jack. The unit support includes a base plate, a bottom plate, and support legs. The bottom plate is fixedly connected to support legs corresponding to the gas turbine bracket. The top of the support legs is detachably connected to the gas turbine bracket. A lifting lug is provided at the lower part of the support legs. A through hole is provided on the bottom plate corresponding to the position of the lifting lug. The base plate is located below the through hole. The movable block is slidably located within the through hole. The jack is placed between the movable block and the lifting lug. When the jack is raised, the movable block moves downward relative to the bottom plate, and its lower part abuts against the base plate, forming a gap between the bottom plate and the base plate, thereby raising the gas turbine. In practical use, this technology requires the use of movable blocks that mate with the through holes, resulting in a complex structure. Furthermore, the lifting lugs are horizontal plates welded to the lower part of the outriggers. During frequent lifting or lifting of extremely heavy units, this structure is prone to weld cracking or plastic deformation of the lifting lugs. Therefore, this technology suffers from structural complexity, operational complexity, and low safety. Summary of the Invention
[0004] The purpose of this utility model is to provide a new type of elevation adjustment component for gas turbine units that is simple in structure, easy to use, and highly safe, in order to address the shortcomings of the existing technology.
[0005] The technical objective of this utility model is achieved through the following technical solution: A novel elevation adjustment component for a gas turbine unit includes a base plate, a unit support, and a jack. Gas turbine supports are symmetrically arranged on both sides of the gas turbine. The unit support includes a support plate. The base plate is larger than the support plate, and has multiple studs. The support plate has through holes that mate with the studs, and the base plate and support plate are bolted together. Vertical supports are symmetrically arranged on the support plate corresponding to the gas turbine supports, and these vertical supports are detachably connected to the gas turbine supports. Irregularly shaped supports are fixedly connected to the lower part of opposite sides of the vertical supports. Each irregularly shaped support has a lifting lug that mates with the upper end of the jack. The support plate has a U-shaped through groove on the lower side of the lifting lug, corresponding to the width of the supporting plate, for the lower part of the jack to be inserted. After the jack is placed in the U-shaped through groove, its lower end abuts against the upper side of the base plate, and its upper end aligns with the lifting lug.
[0006] Preferably, the vertical support consists of a vertical plate arranged along the length of the support plate, side plates symmetrically arranged on both sides of the vertical plate and arranged along the width of the support plate, and a support platform fixedly arranged at the upper end of the vertical plate and the side plates.
[0007] Preferably, the support platform is provided with a support platform screw, and the gas turbine bracket is provided with a bracket through hole that cooperates with the support platform screw. The support platform and the gas turbine bracket are connected by fixing bolts.

[0009] Preferably, a shaped support is fixedly connected to the lower part of the side plate on the opposite side of the vertical support; the lifting ear plate of the shaped support is arranged along the width direction of the support plate and parallel to the support plate; multiple support plates are provided on the upper and lower sides of the lifting ear plate and along the width direction of the support plate.
[0010] Preferably, the support plate includes two lower support plates spaced apart on the underside of the lifting lug plate and an upper support plate corresponding to the lower support plates and disposed on the upper side of the lifting lug plate; the distance between the lower support plates is sufficient for the top of the jack to pass through, so that the top of the jack fits with the bottom surface of the lifting lug plate.
[0011] Preferably, the upper support plates further include a reinforcing upper support plate; the reinforcing upper support plate is connected to the upper support plate by a side stiffener plate.
[0012] Preferably, the irregular support further includes a base, and the lifting ear plate and the support plate are fixedly mounted on the base; The base is detachably connected to the side plate on the opposite side of the vertical support.
[0013] Preferably, the support plate has weight-reducing grooves on both sides along its length.

This utility model includes a base plate, a unit support, a gas turbine bracket, and a jack; by using a special-shaped support and a U-shaped through-slot in conjunction with the jack, the elevation of the gas turbine unit can be safely, accurately, and efficiently adjusted without the need for large hoisting equipment, significantly reducing operational risks and workload. This technical measure has the advantages of simple structure, convenient use, and high safety.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0022] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0023] Example 1 like Figure 1 — Figure 3As shown, a novel elevation adjustment component for a gas turbine unit includes a base plate 2, a unit support, and jacks 7. Gas turbine supports are symmetrically arranged on both sides of the gas turbine 1. The unit support includes a support plate 3. The base plate 2 is larger than the support plate 3. Multiple studs 21 are provided on the base plate 2, and through holes 32 that mate with the studs 21 are provided on the support plate 3. The base plate 2 and the support plate 3 are connected by bolts (not shown in the figure). Vertical supports are symmetrically arranged on the support plate 3 corresponding to the gas turbine supports. The vertical support 4 is detachably connected to the gas turbine support. A shaped support 5 is fixedly connected to the lower part of the opposite side of the vertical support 4. The shaped support 5 has a lifting lug 51 that mates with the upper end of the jack 7. A U-shaped groove 31 is provided on the lower side of the support plate 3, corresponding to the width of the lifting lug 51, for the lower part of the jack 7 to be inserted. After the jack 7 is placed in the U-shaped groove 31, its lower end abuts against the upper side of the base plate 2, and its upper end corresponds to the lifting lug 51. Loosen the bolts and use the jack 7 to lift the vertical support 4 and the gas turbine unit. A shim 8 of the corresponding size is placed in the gap between the base plate 2 and the support plate 3. By using the shaped support 5 and the U-shaped groove 31 in conjunction with the jack 7, the elevation of the gas turbine unit can be safely, accurately, and efficiently adjusted without large hoisting equipment, significantly reducing operational risks and workload. This technology has the advantages of simple structure, ease of use, and high safety.
[0024] like Figure 1 As shown, gas turbine supports are symmetrically arranged on both sides of the gas turbine 1. In this embodiment, the gas turbine supports include a first gas turbine support 11 and a second gas turbine support 12 symmetrically distributed on both sides of the gas turbine 1.
[0025] like Figure 1 As shown, the base plate 2 is a rectangular flat plate structure. The overall dimensions of the base plate 2 are larger than those of the support plate 3. The support plate 3 can also be a rectangular flat plate structure. To reduce weight, weight-reducing grooves 33 are provided on both sides along the length of the support plate 3.
[0026] like Figure 1 As shown, the base plate 2 has multiple studs 21, and the support plate 3 has through holes 32 that mate with the studs 21. The base plate 2 and the support plate 3 are connected by bolts (not shown in the figure). In actual implementation, the height of the studs 21 is greater than the thickness of the support plate 3, so that the bolts have more adjustment space when adjusting the elevation.
[0027] like Figure 1 As shown, vertical supports 4 are symmetrically arranged on the support plate 3 corresponding to the gas turbine support, and the vertical supports 4 are detachably connected to the gas turbine support. In this embodiment, the support plate 3 is symmetrically arranged with first vertical supports and second vertical supports corresponding to the first gas turbine support 11 and the second gas turbine support 12.
[0028] like Figure 1 As shown, the vertical support 4 consists of a vertical plate 41 arranged along the length of the support plate 3, side plates 42 symmetrically arranged on both sides of the vertical plate 41 and arranged along the width of the support plate 3, and a support platform 43 fixedly arranged on the upper end of the vertical plate 41 and the side plates 42.
[0029] In practical implementation, the upright plate 41 is a square plate, the side plate 42 is a trapezoidal plate, and the support platform 43 is square. This vertical support 4 adopts a composite structure of upright plate 41, trapezoidal side plate 42 and square support platform 43, which significantly enhances the support rigidity and load distribution capacity, and effectively avoids structural deformation during the jacking process.
[0030] In this embodiment, the support platform 43 is provided with a support platform screw 431, and the gas turbine bracket is provided with a bracket through hole that cooperates with the support platform screw 431. The support platform 43 and the gas turbine bracket are connected by fixing bolts (not shown in the figure).
[0031] like Figure 1 As shown, the side plates 42 on opposite sides of the vertical support 4 are connected by reinforcing plates 6. In a specific implementation example, the side plates 42 include a left side plate and a right side plate symmetrically arranged on both sides of the vertical plate 41. The first vertical support includes a first left side plate and a first right side plate, and the second vertical support includes a second left side plate and a second right side plate. In this embodiment, the side plates 42 on opposite sides of the vertical support 4 are connected by reinforcing plates 6, that is, the first right side plate and the second left side plate on opposite sides of the first vertical support and the second vertical support are connected by reinforcing plates 6. In actual use, there can be multiple reinforcing plates 6. In this embodiment, there are two reinforcing plates 6 spaced apart along the width direction of the support plate 3. This technical measure greatly enhances the overall rigidity and resistance to lateral deformation of the vertical support 4, ensuring the absolute stability of the support system during the lifting process.
[0032] like Figure 1 As shown, a shaped support 5 is fixedly connected to the lower part of the side plate 42 on the opposite side of the vertical support 4; the lifting ear plate 51 of the shaped support 5 is arranged along the width direction of the support plate 3 and parallel to the support plate 3; multiple support plates are respectively provided on the upper and lower sides of the lifting ear plate 51 along the width direction of the support plate 3. In this embodiment, the shaped support 5 is fixedly connected to the lower part of the first left side plate and the second right side plate on the opposite side of the first vertical support and the second vertical support. Among them, the shaped support 5 connected to the lower left side of the first left side plate and the shaped support 5 connected to the lower right side of the second right side plate are symmetrically arranged. By setting multiple support plates on the upper and lower sides of the lifting ear plate 51, the shaped support 5 forms a stable three-dimensional support frame, which greatly enhances the bending stiffness and load-bearing strength of the ear plate and effectively avoids the risk of local deformation during lifting.
[0033] like Figure 2As shown, in this embodiment, the support plate includes two lower support plates 52 spaced apart below the lifting lug plate 51, and an upper support plate 53 corresponding to the lower support plates 52 and positioned above the lifting lug plate 51. The distance between the lower support plates 52 is sufficient for the top of the jack 7 to pass through, allowing the top of the jack 7 to engage with the bottom surface of the lifting lug plate 51. The distance between the two lower support plates 52 is not less than the width of the U-shaped through groove 31. In specific implementations, the lower support plates 52 and the upper support plates 53 can be square, trapezoidal, etc. By adopting this technical measure, while ensuring the accurate positioning and smooth passage of the jack 7, it works in conjunction with the upper support plate 53 to form a box-shaped load-bearing frame, greatly improving the load-bearing stability and deformation resistance of the lifting lug plate 51.
[0034] In this embodiment, a reinforcing upper support plate 54 is also included between the upper support plates 53; the reinforcing upper support plate 54 is connected to the upper support plate 53 by side stiffener plates 55. This technical measure forms a multi-directional support system, effectively dispersing the concentrated stress during jacking and significantly enhancing the overall rigidity and fatigue resistance of the ear plate structure.
[0035] Working principle: When elevation adjustment is required, loosen the bolts and use jack 7. When jack 7 is raised, its top end abuts against the bottom surface of the lifting ear plate 51. When jack 7 is raised further, the vertical support 4 rises and lifts the gas turbine 1 unit. Then, place shims 8 in the gap between the base plate 2 and the support plate 3.
[0036] Example 2 like Figure 4 As shown, the other contents of this embodiment are the same as those of Embodiment 1, except that: the irregular support 5 also includes a base 56, and the lifting ear plate 51 and the support plate are fixedly mounted on the base 56; the base 56 is detachably connected to the side plate 42 on the opposite side of the vertical bracket 4. In specific implementation, the side plate 42 on the opposite side of the vertical bracket 4 is provided with multiple connecting screw holes (not shown in the figure), and correspondingly, the base 56 is provided with connecting through holes (not shown in the figure) that cooperate with the connecting screw holes. The base 56 and the side plate 42 on the opposite side of the vertical bracket 4 are connected by connecting bolts 421. By using a detachable base 56 and connecting bolts 421, modular installation and replacement of the irregular support 5 are achieved, which greatly improves maintenance convenience and reduces the overall maintenance cost of the support structure.
[0037] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
