[0023] Please see Figure 1-6 This invention provides a technical solution: a support fixture for disassembling and assembling rotating components of a gas turbine, comprising a support mechanism and a transport mechanism, specifically: The support structure is used for the load-bearing installation of the transport mechanism. The support structure includes a main support column 1, a secondary support column 2, a slide rail support 3, a support slide rail 4, and a connecting crossbeam 5, as shown in the attached diagram. Figure 1 As shown, the slide rail support 3 and the supporting slide rail 4 are both set in pairs. The main support column 1 and the auxiliary support column 2 are both installed on the lower part of the slide rail support 3 for installation support. Specifically, there are four main support columns 1, which are vertically fixed to the lower rear side of the slide rail support 3 by brackets. The auxiliary support columns 2 are set in pairs, and are vertically fixed to the lower front side of the slide rail support 3 by brackets. Both the main support columns 1 and the auxiliary support columns 2 are made of Q345B steel welded into a rectangular frame. To improve the stability of the support connection, a 10mm thick steel plate is welded to the bottom of the column. The bottom plate of the column is fitted with M30×150mm adjustable anchor bolts to achieve rapid movement and rigid fixation of the tooling. To facilitate the adjustment of the auxiliary support column 2 for connection support, see attached... Figure 4 As shown, a telescopic support leg 7 is adjustablely installed at the lower part of the secondary support column 2, and a docking support is fixedly installed at the upper part of the telescopic support leg 7. The docking support is fitted and supported by the slot side of the lower part of the secondary support column 2. In order to facilitate adjustment of the limit, a fastening bolt is installed in the hole opened in the middle of the secondary support column 2. A long slot is opened through the middle of the telescopic support leg 7, and the middle part of the fastening bolt is movably fitted with the long slot. After installation, the telescopic support leg 7 is fixedly installed to the secondary support column 2 by the fastening bolt.

[0024] The connecting beam 5 is detachably installed between the two sets of main support columns 1, and is used for the middle joint support connection of the two main support columns 1, as shown in the attached figure. Figure 3 As shown, there are four connecting beams 5. To facilitate the docking and installation, mounting end seats are fixedly installed at both ends of the connecting beams 5. The mounting end seats are fixedly installed to the inner side of the main support column 1 by bolts. The support width of the device can be controlled and adjusted by replacing the connecting beams 5. To facilitate the installation and adjustment, an elliptical groove for bolt installation is provided in the middle of the mounting end seat.

[0025] The support rail 4 is used for the moving support of the transport mechanism. The support rail 4 is movably and adjustablely installed on the upper part of the rail support 3, as shown in the attached figure. Figure 4 As shown, the slide rail support 3 uses thick channel steel as the supporting guide rail steel beam for the slide rail 4. The slide rail 4 is supported and installed on the upper part of the slide rail support 3. In order to improve the installation stability of the slide rail 4, limit seats 12 are fixedly installed on both sides of the slide rail support 3. The limit seats 12 are provided with multiple equidistantly distributed on the side of the slide rail support 3. After installation, the side of the slide rail 4 slides and fits into the limit seats 12 for support. To prevent the slide rail 4 from moving out, as shown in the attached figure... Figure 6 As shown, an end limit seat is fixed on the upper inner side of the limit seat 12. The connecting beam 5 is set as a split type. By replacing the connecting beam 5, the support width of the device can be controlled and adjusted. The split support slide rail 4 is supported and installed by the slide rail support 3. The support slide rail 4 is guided by the limit seat 12 and limited by the limit bolt 9 for working installation. The overall support length of the device can be adjusted by telescopic adjustment, which greatly improves the working flexibility of the device. The device can meet the disassembly and assembly support requirements of gas turbines of different sizes, reduce the procurement cost of special brackets by 60%, and reduce the annual maintenance cost by 250,000 yuan.

[0026] As attached Figure 6 As shown, in order to achieve the locking limit of the adjusted support slide rail 4, a connecting end seat 8 is fixedly installed at the rear of the support slide rail 4. For convenient adjustment and positioning of the support slide rail 4, see attached... Figure 4 As shown, equidistant limit screw holes are evenly spaced on the upper rear side of the slide rail support 3. The inner side of the limit screw holes is threaded with limit bolts 9 for locking the connecting end seat 8. To facilitate installation and adjustment, an elliptical groove for installing the limit bolts 9 is provided in the middle of the connecting end seat 8. To facilitate docking with the ground support point, docking side seats 13 are fixedly installed on the inner front side of both sets of support slide rails 4. The docking side seats 13 have bolt mounting holes in the middle.

[0027] The transport mechanism is used for disassembly, support, and docking of rotating components of the gas turbine. The transport mechanism includes roller seats 6 and support rollers 14. Four roller seats 6 are provided, as shown in the attached diagram. Figure 5 As shown, the support roller 14 is rotatably mounted on the lower part of the roller seat 6 via a rotating shaft. The roller seat 6 is movably mounted on the upper part of the support slide rail 4 via the support roller 14. Specifically, to achieve the guiding support of the roller seat 6, a guide groove is provided in the middle of the support slide rail 4. The support roller 14 is rolled and supported on the bottom side of the guide groove. A slide rail support and loading working structure is adopted, in which the roller seat 6 is used as a load-bearing support structure and docked with the lower part of the gas turbine. The support slide rail 4 provides movable support for the roller seat 6. During operation, the roller seat 6 is moved and supported by the support roller 14. External traction assistance facilitates the convenient and quick side-shifting and transport of the disassembled gas turbine. The transport structure is simple and stable, offering better operational convenience and stability compared to traditional hoisting methods. Furthermore, the use of sliding rails replaces manual assistance for stability, eliminating the need for personnel to handle heavy loads. This significantly reduces manpower consumption during gas turbine disassembly and greatly improves operational safety. In practice, the disassembly and assembly time per operation has been reduced from 6 hours to 2 hours, and the required workforce has been reduced from 6 to 2 people. For convenient docking and installation with gas turbine components, see attached... Figure 5 As shown, the upper part of the roller seat 6 is provided with docking bolt holes and traction docking holes. In order to realize the displacement support and limit of the roller seat 6, as shown in the attached figure... Figure 6 As shown, inner limit supports 10 are fixedly installed on both the front and rear sides inside the guide groove cavity. In order to improve the buffer support and protection of the inner limit supports 10, a buffer rubber pad 11 is fixedly installed on the inner side of the inner limit supports 10. Specifically, the buffer rubber pad 11 is a neoprene rubber soft pad with a thickness of 5mm.

[0028] Working principle or structural principle: Unit assembly: Select the corresponding connecting beam 5 according to the model and specifications of the gas turbine to be disassembled and assembled. Then, use bolts to connect and install multiple sets of connecting beams 5 between two adjacent sets of main support columns 1. Then, align and install the support slide rail 4 on the upper part of the slide rail support 3. Then, use the limit bolt 9 to lock and limit the installed support slide rail 4. Finally, support the roller seat 6 on the upper part of the support slide rail 4 to complete the assembly and installation of the unit. Device installation: The tooling is connected to the skid base with bolts to complete the overall installation and positioning of the device. Then, the bolts on the side of the telescopic support leg 7 at the bottom of the auxiliary support column 2 are loosened to make the base side of the telescopic support leg 7 stably contact the ground for support. After that, the bolts are tightened to complete the locking limit of the telescopic support leg 7 after adjustment, ensuring that the device is stably and fixedly supported and installed on the ground. Then, according to the longitudinal distance of the gas turbine, the support length of the support rail 4 is adjusted by horizontal sliding with the limit bolt 9 loosened. After adjustment, the bolt mounting hole in the middle of the docking side seat 13 at the front of the support rail 4 is aligned and overlapped with the screw hole on the upper part of the base. The docking side seat 13 is then docked and installed with the base with bolts. After completion, the adjusted support rail 4 is locked and limited by the limit bolt 9 to complete the installation of the device. Disassembly and Loading: The rotating components of the gas turbine are disassembled and separated. Then, the positions of the four sets of roller seats 6 are adjusted. After completion, the components are lifted by the lifting beam and placed on the upper part of the roller seats 6 in the middle of the support slide rail 4. After positioning, adjustment and installation are completed, and the components are locked with bolts. Then, two sets of hand chain hoists are installed on the front and rear sides of the device respectively. The disassembled components are moved and pulled by the two sets of hand chain hoists. One of the two hand chain hoists is pulled and the other is released. The two hand chain hoists work in sync. While realizing the lateral movement of the disassembled components, it can also prevent the device from slipping and moving. The device can complete the removal or pushing back of the components. During the process, the slide rail support replaces manual assistance for stabilization. The operators do not need to touch the heavy objects. This reduces the manpower consumption of gas turbine disassembly operations and greatly improves the operation safety.

[0029] In summary, the sliding rail-supported loading structure uses the roller seat 6 as the load-bearing support structure, which is connected and supported to the lower part of the gas turbine. The roller seat 6 is moved and supported by the support rail 4. During operation, the side-moving and loading of the disassembled gas turbine can be easily and quickly completed with the assistance of external traction. The transport structure is simple and the support is stable. Compared with the traditional hoisting and moving method, it has better operation convenience and working stability. Moreover, the sliding rail support replaces manual assistance for stabilization, and the operators do not need to touch the heavy objects. This reduces the manpower consumption of gas turbine disassembly operations and greatly improves the operation safety. The split bracket installation structure is adopted, and the connecting beam 5 is set as a split type. By replacing the connecting beam 5, the support width of the device can be controlled and adjusted. The split support rail 4 is supported and installed by the sliding rail support 3. The support rail 4 is guided by the limiting side seat 12 and limited by the limiting bolt 9 for working installation. The overall support length of the device can be adjusted by telescopic adjustment, which greatly improves the working flexibility of the device and enables the device to meet the disassembly and assembly support requirements of gas turbines of different sizes.
