Description

Technical Field

[0001] This invention relates to the field of gas turbine transportation, and more specifically to a gas turbine transportation device with a modular support structure. Background Technology

[0002] As a high-precision large-scale power equipment, the core components of a gas turbine, such as its rotor and blades, are extremely sensitive to vibration, impact, and external environmental factors. During long-distance transportation, the vibration and impact loads generated by road bumps, vehicle start-stop, and braking can easily lead to wear, deformation, or even damage to the precision components inside the gas turbine. Therefore, gas turbine transportation equipment needs to have both reliable support and fixing functions and efficient vibration reduction and protection functions.

[0003] Currently, common gas turbine transport devices mainly fall into two categories: box-type transport devices and frame-type transport devices. Box-type transport devices typically employ a closed box structure to house the gas turbine entirely within the box, thus protecting it from the external environment. However, existing frame-type transport devices generally have several support seats on the base to abut against specific mounting holes or flange faces of the gas turbine, achieving rigid fixation of the gas turbine. At the same time, several vibration dampers are installed under the base to attenuate bumps and vibrations during transport.

[0004] In the prior art, such as the gas turbine transport box disclosed in Chinese utility model patent CN219948900U, the gas turbine is rigidly fixed by a movable flange frame and a fixed frame. Although this solution can achieve reliable positioning of the gas turbine, specifically, the support seat only undertakes the function of static load support, and the vibration damper adopts a passive vibration damping element with preset fixed damping parameters. Its damping characteristics remain unchanged after being set once before transportation.

[0005] However, during actual transportation, the load state of the gas turbine is dynamically changing. On the one hand, different models of gas turbines have different weights, and the same damper parameters cannot meet the optimal damping requirements under different load conditions. The problems of insufficient damping effect under heavy load and excessive damping stiffness under light load coexist. On the other hand, under different driving conditions such as acceleration, braking, turning and road bumps, the dynamic load on each support point changes constantly. The fixed damping damper cannot make differentiated adjustments according to the real-time force state of each support point, resulting in insufficient damping at some support points and excessive damping at others. This causes the overall attitude of the gas turbine to tilt, aggravates the relative displacement and friction damage of internal components, and ultimately leads to damage to the gas turbine during transportation.

[0006] Therefore, the present invention provides a gas turbine transportation device with a modular support structure to solve the above problems. Summary of the Invention

[0007] This invention addresses the technical problems existing in the prior art by providing a gas turbine transportation device with a modular support structure.

[0008] The technical solution of the present invention to solve the above technical problems is as follows: a gas turbine transportation device with a modular support structure, including an upper cover and a base assembly, wherein a support mechanism is provided inside the base assembly, and a dynamic adjustment component is provided on the lower surface of the base assembly; The dynamic adjustment component includes a support cylinder arranged in a rectangular array on the lower surface of the base assembly. A piston is slidably connected inside the support cylinder. The piston is sealed to the inner wall of the support cylinder. A support seat is fixedly connected to the upper surface of the piston and slidably connected to the support cylinder. The support seat is fixedly connected to the lower surface of the base assembly. An air inlet pipe is fixedly connected to the side of the support cylinder. An exhaust unit is provided at one end of the air inlet pipe.

[0009] In a preferred embodiment, the support mechanism includes reinforcing ribs fixedly connected inside the base assembly, wherein two of the reinforcing ribs are provided with sealing cavities, and a sealing plate is slidably connected inside the sealing cavity, and the sealing plate is sealed to the sealing cavity.

[0010] In a preferred embodiment, the support mechanism further includes a front support seat and a rear support seat that are symmetrically fixedly connected to both sides of the upper surface of the sealing plate, and the front support seat and the rear support seat correspond one-to-one.

[0011] In a preferred embodiment, the exhaust unit includes an air collection box fixedly connected to one end of the air intake pipe via a flange. A connecting pipe is fixedly connected to the upper surface of the air collection box via a flange. One end of the connecting pipe passes through the base assembly and the reinforcing rib and communicates with the sealing cavity.

[0012] In a preferred embodiment, the upper cover has an arched structure and is detachably fastened to the base assembly. The upper cover and the base assembly are connected by a flange and fixed with bolts, and a sealing element is installed between the flanges.

[0013] In a preferred embodiment, the top of the cover is provided with a top lifting lug, and the side of the cover is provided with an observation window. Both sides of the cover are provided with pedals in a rectangular array, and both sides of the base assembly are horizontally fixedly connected with bottom lifting lugs.

[0014] In a preferred embodiment, the lower surface of the base assembly is fixedly connected with vibration dampers in a rectangular array, and the bottom of the vibration dampers is on the same horizontal line as the bottom of the support cylinder.

[0015] In a preferred embodiment, each of the multiple gas collection boxes is fixedly fitted with a support sleeve, and a support frame is fixedly connected to the opposite sides of every two laterally symmetrical support sleeves.

[0016] In a preferred embodiment, the upper surfaces of both the front support and the rear support are provided with adjusting shims, and the upper surfaces of the adjusting shims are provided with supporting members.

[0017] In a preferred embodiment, the two support frames are fixedly connected to each other on opposite sides by a reinforcing plate.

[0018] The beneficial effects of this invention are: 1. This invention achieves this by coordinating multiple components in a dynamic adjustment assembly. When the front and rear support seats bear the weight of the gas turbine, the support seats slide downwards, driving the sealing plate to compress the air inside the sealing cavity. The compressed air enters the gas collection box through the connecting pipe, and then enters the interior of each support cylinder through the connecting pipe, pushing the piston and support seats upwards. During this process, the heavier the gas turbine, the greater the compression of the sealing cavity, and the higher the air pressure entering each support cylinder. The supporting force of the piston in the support cylinder on the base assembly increases accordingly, and the initial compression of the damper fixedly connected to it increases synchronously. The damping characteristics are automatically adjusted to high damping, and vice versa when the load is light. Thus, the dynamic adjustment assembly can automatically match the optimal parameters according to the actual load state, solving the technical problem that traditional fixed damping dampers cannot take into account different load conditions. 2. In this invention, each sealed cavity is connected in parallel with each support cylinder through a connecting pipe to form a closed air pressure network. During transportation, when the vehicle accelerates, brakes, or turns, the dynamic load on each support point changes instantaneously. When the pressure on a certain support point increases, more gas is discharged from the sealed cavity at that point into the common air passage. The gas automatically flows to the support cylinder with less pressure, pushing the corresponding piston and support seat to rise and compensate, thereby achieving dynamic automatic balance of the support force at each support point. This effectively suppresses the tilting of the gas turbine caused by uneven force at each point in the traditional independent vibration reduction scheme, and avoids relative displacement and friction damage to internal components caused by tilting. 3. The top cover of this invention adopts an arched structure and is detachably connected to the base assembly via flanges. Sealing elements are installed between the flanges, enabling rapid construction and disassembly of the enclosed space. This facilitates the installation and removal of the gas turbine, and the sealing structure effectively isolates external moisture, salt spray, and dust. The top of the top cover is equipped with a top lifting lug, and the sides are equipped with observation windows and a footboard. The base is equipped with bottom lifting lugs on both sides, which facilitates the hoisting and transportation of the entire device and allows for easy observation and inspection of the internal gas turbine status during transportation. Each component adopts a modular design and can be reused multiple times, reducing transportation costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figures 1-8 The present invention provides a gas turbine transport device with a modular support structure, including an upper cover 1 and a base assembly 2. The base assembly 2 is provided with a support mechanism inside and a dynamic adjustment component is provided on the lower surface of the base assembly 2. The upper cover 1 has an arched structure, made of high-strength composite material or metal sheet, and is detachably fastened to the base assembly 2. The upper cover 1 and the base assembly 2 are connected by flanges and fixed with bolts. A sealing element, such as a rubber sealing ring or a silicone sealing gasket, is installed between the flanges to seal the enclosed space and prevent external moisture, salt spray, and dust from entering. The top of the upper cover 1 is equipped with a top lifting lug 17, which is fixed to the upper cover 1 by welding or bolts. Multiple top lifting lugs 17 are symmetrically arranged along the longitudinal center line of the upper cover 1 for lifting and unloading operations. The side of the upper cover 1 is provided with an observation window 18, which is made of tempered glass or plexiglass. An observation window 18 is installed at the connection between the observation window 18 and the upper cover 1. Sealing strips are provided to facilitate observation and inspection of the internal gas turbine during transportation. Both sides of the top cover 1 are provided with a rectangular array of pedals 19. The pedals 19 are grating plates or anti-slip steel plates, which are welded and fixed to the outer side wall of the top cover 1. The pedals 19 are used for operators to stand on for high-altitude operations such as hook installation and bolt tightening. Both sides of the base assembly 2 are horizontally fixedly connected with bottom lifting lugs 20. Multiple bottom lifting lugs 20 are arranged at intervals along the length of the base assembly 2. On the one hand, they are used to select different lifting points according to the different centers of gravity of the gas turbine during hoisting. On the other hand, the bottom lifting lugs 20 can be used to fix the entire device to the transport vehicle by binding straps or locking chains to prevent the device from shifting relative to the carriage during transportation. The base assembly 2 is a rectangular frame structure welded from steel profiles; The support mechanism includes reinforcing ribs 8 fixedly connected inside the base assembly 2. Two reinforcing ribs 8 are provided with sealing cavities 9. A sealing plate 10 is slidably connected inside the sealing cavity 9, and the sealing plate 10 and the sealing cavity 9 are sealed together. The support mechanism also includes a front support seat 11 and a rear support seat 12 symmetrically fixedly connected to both sides of the upper surface of the sealing plate 10. The front support seat 11 and the rear support seat 12 correspond one-to-one. That is, the front support seat 11 is located on the front side of the upper surface of the sealing plate 10, and the rear support seat 12 is located on the rear side of the same upper surface of the sealing plate 10. The two are arranged in pairs. The reinforcing rib 8 is a longitudinal reinforcing rib that divides the interior of the base assembly 2 into multiple independent grid areas. The reinforcing rib 8 is used to improve the overall rigidity and load-bearing capacity of the base assembly 2 and to distribute the load of the gas turbine to various parts of the base assembly 2. The sealing plate 10 is a plate-shaped component adapted to the inner wall of the sealing cavity 9, and a sealing ring is embedded on the circumferential side of the sealing plate 10 to achieve a sealing arrangement between the sealing plate 10 and the sealing cavity 9 and prevent gas leakage. Support sleeves 21 are fixedly fitted onto the surfaces of multiple gas collection boxes 15. The support sleeves 21 are annular components with an inner diameter that matches the outer diameter of the gas collection box 15. The support sleeves 21 are fitted onto the outside of the gas collection box 15 and fixedly connected to it. Support frames 22 are fixedly connected to the opposite sides of every two transversely symmetrical support sleeves 21. The support frames 22 are transversely extending beam-type components, with their two ends welded or bolted to the support sleeves 21 on both sides. The support frames 22 are used to connect the gas collection boxes 15 into a whole, improving the overall structural stability. Adjusting shims 13 are provided on the upper surfaces of the front support seat 11 and the rear support seat 12. Support members 14 are provided on the upper surfaces of the adjusting shims 13. Reinforcing plates are fixedly connected to the opposite sides of the two support frames 22. The reinforcing plates are longitudinally extending plate-shaped components, with their two ends fixedly connected to the two support frames 22 to further improve the overall rigidity. The adjusting shims 13 are a group of metal shims of different thicknesses. By selecting adjusting shims 13 of different thicknesses, the height of the front support 11 and the rear support 12 can be initially leveled to adapt to the differences in installation dimensions of different types of gas turbines. Support component 14 is a positioning block or support plate that is adapted to the mounting hole or flange surface at the bottom of the gas turbine, and is used to directly abut against the gas turbine to achieve rigid support and fixation of the gas turbine; The exhaust unit includes an air collection box 15 fixedly connected to one end of the air intake pipe 6 via a flange. The air collection box 15 is a hollow box structure used to collect compressed air from each sealed cavity 9. A connecting pipe 16 is fixedly connected to the upper surface of the air collection box 15 via a flange. The connecting pipe 16 is a rigid pipe fitting. One end of the connecting pipe 16 passes through the base assembly 2 and the reinforcing rib 8 and is connected to the sealed cavity 9. The dynamic adjustment component includes a support cylinder 3 arranged in a rectangular array on the lower surface of the base assembly 2. The support cylinder 3 is a cylindrical structure with an open upper end and a closed lower end. A piston 4 is slidably connected inside the support cylinder 3. The piston 4 is sealed to the inner wall of the support cylinder 3. The piston 4 is a disc-shaped component adapted to the inner wall of the support cylinder 3. A sealing ring is embedded on the circumferential side of the piston 4 to achieve a sealing between the piston 4 and the inner wall of the support cylinder 3 and prevent gas leakage. A support seat 5 is fixedly connected to the upper surface of the piston 4 and slidably connected to the support cylinder 3. The upper end of the support seat 5 is fixedly connected to the lower surface of the base assembly 2 by bolts or welding. An air inlet pipe 6 is fixedly connected to the side of the support cylinder 3. An exhaust unit is provided at one end of the air inlet pipe 6. The support cylinder 3, piston 4 and support seat 5 together form a retractable cylinder structure. The piston 4 divides the internal space of the support cylinder 3 into an upper rod chamber and a lower rodless chamber. The lower rodless chamber is a closed air chamber used to contain compressed air. One end of the air intake pipe 6 is connected to the lower rodless cavity of the support cylinder 3; The lower surface of the base assembly 2 is fixedly connected with a rectangular array of shock absorbers 7. The shock absorbers 7 are any one of hydraulic shock absorbers, air spring shock absorbers, or rubber shock absorbers. The upper end of the shock absorbers 7 is fixedly connected to the lower surface of the base assembly 2 by bolts or welding. The lower end of the shock absorbers 7 is a free end, which is used to contact the floor of the transport vehicle to attenuate the bumps and vibrations during transportation. Furthermore, the bottom of the shock absorber 7 and the bottom of the support cylinder 3 are on the same horizontal line, that is, the lower end face of the shock absorber 7 in the free state is flush with the lower end face of the support cylinder 3, so as to ensure that when the device is placed on the transport vehicle, the shock absorber 7 and the support cylinder 3 can touch the ground at the same time and share the load.

[0023] Specifically, before using the modular support structure gas turbine transport device, the position configuration and height pre-adjustment of the front support seat 11 and the rear support seat 12 are completed inside the base assembly 2 according to the model and external dimensions of the gas turbine to be transported. According to the design position of the bottom mounting hole or flange face of the gas turbine, the operator installs the front support seat 11 and the rear support seat 12 at the corresponding positions on the upper surface of the sealing plate 10 to ensure that the positions of the front support seat 11 and the rear support seat 12 match the actual installation points of the gas turbine. Subsequently, based on the theoretical weight and center of gravity distribution of the gas turbine, adjusting shims 13 of appropriate thickness are selected and placed on the upper surfaces of each front support 11 and rear support 12, and support members 14 are placed above the adjusting shims 13 so that the upper surfaces of each support member 14 are basically in the same horizontal plane, thus initially completing the adjustment of the support height. After completing the above preparations, the base assembly 2 is hoisted onto the floor of the transport vehicle, so that the lower ends of each shock absorber 7 and each support cylinder 3 on the lower surface of the base assembly 2 simultaneously contact the floor of the transport vehicle. The operator uses the bottom lifting lugs 20 on both sides of the base assembly 2 to initially fix the base assembly 2 to the floor of the transport vehicle using straps or locking chains to prevent the base assembly 2 from sliding during the hoisting process. Subsequently, the gas turbine to be transported is hoisted to the top of the base assembly 2 and slowly lowered so that the mounting holes or flanges at the bottom of the gas turbine are aligned and in contact with the upper surfaces of each support member 14. Under the action of the gas turbine's own weight, the support member 14 is compressed. The pressure is transmitted to the sealing plate 10 through the front support seat 11 and the rear support seat 12, causing the sealing plate 10 to slide downward along the inner wall of the sealing cavity 9, compressing the air inside the sealing cavity 9. The compressed air enters the lower rodless cavity of each support cylinder 3 through the connecting pipe 16, the gas collection box 15 and the air inlet pipe 6, pushing the piston 4 to move upward. The piston 4 applies an upward supporting force to the base assembly 2 through the support seat 5. As the gas turbine is fully in place, the air pressure in the sealed cavity 9 and the air pressure in each support cylinder 3 reach dynamic equilibrium. Each piston 4 and support seat 5 stabilizes in its current position. Each shock absorber 7 is compressed to its initial position corresponding to the current load under the combined action of the gravity of the base assembly 2 and the load of the gas turbine. The damping characteristics of the shock absorber 7 automatically adapt to the current load state. During this process, the operator can judge whether the force on each support point is balanced by observing whether the gap between the lower end of each support cylinder 3 and the floor of the carriage is consistent. If an abnormal gap is found at the lower end of a certain support cylinder 3, the adjusting shim 13 at the corresponding position can be further fine-tuned to make each support point bear the load evenly. After the gas turbine is in place, the operator uses bolts to rigidly fix the mounting holes or flange faces of the gas turbine to the support 14 to ensure that the gas turbine will not be displaced or shaken during transportation. Then, the upper cover 1 is hoisted to the top of the base assembly 2, so that the lower flange of the upper cover 1 is aligned with the upper flange of the base assembly 2. The upper cover 1 is slowly lowered so that the two flange faces are in contact. A seal is installed between the flange faces. Then, the upper cover 1 and the base assembly 2 are locked and fixed with bolts to form a closed receiving space. Operators can stand on the footboards 19 on both sides of the top cover 1 to easily carry out high-altitude operations such as hook installation and bolt tightening. After the enclosure is completed, the entire device is lifted onto the transport vehicle by the top lifting lugs 17 on the top of the top cover 1, and the device is tied and fixed to the vehicle by the bottom lifting lugs 20 on both sides of the base assembly 2 to complete the loading. During transportation, when the vehicle travels on a bumpy road, the base assembly 2 is subjected to vertical vibration impact from the road surface. When the impact load on a certain support point increases instantaneously, the sealing plate 10 at that point further compresses the air in the sealing cavity 9, increasing the amount of gas discharged from the sealing cavity 9. This gas enters the gas collection box 15 through the corresponding connecting pipe 16 and automatically flows through the air inlet pipe 6 to the support cylinder 3 with relatively low air pressure, pushing the piston 4 and support seat 5 in the support cylinder 3 to rise, applying additional support force to the base assembly 2, thereby achieving dynamic automatic balance of support force at each support point. Meanwhile, each damper 7 expands and contracts with the vibration of the base assembly 2, and its damping characteristics are adjusted in real time according to the changes in air pressure in each support cylinder 3, always maintaining the optimal damping parameters that match the current load state, effectively attenuating vibration energy and protecting the gas turbine from damage by vibration and impact. When the vehicle brakes suddenly or turns, the gas turbine tends to tilt forward or to the side due to inertia. The load on the support points at the front or side increases instantaneously. At this time, the sealing plate 10 at the corresponding position accelerates the compression of the air in the sealing cavity 9 and quickly delivers the gas to the support cylinder 3 with a smaller load through the air pressure linkage network. This redistributes the support force of each support point, effectively suppresses the tilt of the gas turbine, and avoids damage caused by the relative displacement and friction of internal components. Upon arrival at the destination, the operator first removes the connecting bolts between the top cover 1 and the base assembly 2, and lifts the top cover 1 off using the top lifting lug 17 to expose the gas turbine. Then, the connecting bolts between the gas turbine and the support 14 are removed, and the gas turbine is lifted off the base assembly 2 and removed. During the removal process, as the gas turbine is gradually lifted, the load on the front support 11 and the rear support 12 gradually decreases. Under the action of the residual air pressure in the sealing cavity 9, the sealing plate 10 slides upward and resets. The compressed air in each support cylinder 3 flows back to the sealing cavity 9 through the connecting pipe 16 and the air collection box 15. The piston 4 and the support 5 then reset downward, and the shock absorber 7 returns to its initial position in a free state. Finally, the base assembly 2 is lifted off the transport vehicle, completing a complete transport operation. After completing a transportation operation, all components of the device can be disassembled. The easily damaged parts such as seals and adjusting shims 13 can be replaced. The remaining structural parts can be reused for the next transportation task after being inspected and confirmed to be free of deformation and cracks. For different models of gas turbines, only the corresponding support parts 14 and adjusting shims 13 need to be replaced to achieve compatibility. There is no need to replace the entire base assembly 2, which has good versatility and economy.
