Description

Technical Field

[0001] This utility model relates to the technical field of turbine support structure, specifically a turbine flexible support structure. Background Technology

[0002] A steam turbine is a rotary steam power unit, typically vertically supported on a base by a support structure, which relies on its own rigidity for support. Existing support structures cannot adjust the turbine's position according to changes in the rigidity of the support structure, leading to stress between the turbine and connecting components. A current patent, CN218409367U, describes a flexible support structure for a steam turbine. This structure uses a fastening mechanism to horizontally install the support member between the turbine body and the support member. Fastening bolts and a second bolt secure the support member to the turbine body. This horizontal installation not only provides auxiliary support but also eliminates axial and radial forces.

[0003] In the aforementioned utility model, only one side of the turbine body is supported by the support frame and support components, but the bottom of the turbine body is not supported. This not only results in poor support effect, but also affects the service life of the support structure.

[0004] Therefore, we have made improvements to this by proposing a turbine flexible support structure. Utility Model Content

Support frame 1 3 and support frame 2 31 are respectively installed at the bottom of the support member 2 and the connecting frame 9. The support member 2 is installed on the connecting frame 9 through a clamping plate 8. By setting support frame 1 3 and support frame 2 31, and cooperating with support member 2 and connecting frame 9, the turbine body 1 can be better supported, improving stability. Compared with the support method in the cited document, this support disperses the pressure and can also better extend the service life of support frame 1 3 and support frame 2 31.

[0024] Support plates are mounted on the top surfaces of support frame 3 and support frame 31 respectively via adjusting bolts 7. Support rods 15 are installed between the support plates and support frames 3 and 31. Support member 2 is fixed to the support plate, and the support plate is fixed to the connecting frame 9 via fastening bolts 5. When the height of the turbine body 1 changes, the height of the support plates can be adjusted via adjusting bolts 7 to adapt to the change in the height of the turbine body 1. The fastening bolts 5 serve to connect and secure the components.

[0025] The connecting frame 9 is L-shaped, and a slot 10 is provided on the top surface of the vertical section of the connecting frame 9. A through groove 11 is provided on one side of the slot 10, and the depth of the slot 10 is greater than the depth of the through groove 11. The clamping plate 8 is clamped in the slot 10, and the support member 2 is slidably connected to the through groove 11. Fixing holes 12 are provided on the connecting frame 9 and the clamping plate 8, and fastening bolts 5 are installed in the fixing holes 12. The clamping plate 8 is fixedly connected to the support member 2. The slot 10 can play a certain clamping and limiting role for the clamping plate 8, and the fastening bolts 5 further enhance the tightness of the connection.

[0026] Adjustment grooves 6 are respectively provided on the front and rear sides of support frame 1 3 and support frame 2 31. Fixing holes 12 are provided on the adjustment grooves 6, and adjusting bolts 7 are threaded into the fixing holes 12. The top of the adjusting bolts 7 is rotatably connected to the bottom of the support plate. The opening of the adjustment grooves 6 facilitates the adjustment of the position of the support plate by rotating the adjusting bolts 7.

[0027] Slide grooves 16 are respectively provided on the left and right sides of support frame 3 and support frame 2 31. A slider 17 is slidably disposed in the slide groove 16, and the slider 17 is fixedly connected to the side of the support rod 15. The support rod 15 slides through support frame 3 and support frame 2 31. The top surfaces of support frame 3 and support frame 2 31 extend to both sides, and the top end of the support rod 15 slides through the extended ends of support frame 3 and support frame 2 31. When adjusting the height of the support plate, the support rod 15 slides along the slide groove 16 through the slider 17, thereby playing a guiding role.

[0028] Limiting blocks 14 are fixedly installed on one end of the bottom surface of the support 2 and the bottom surface of the horizontal section of the connecting frame 9, respectively. Limiting grooves are opened on the top surface of the two support plates, and the limiting blocks 14 are engaged with the limiting grooves.

[0029] A square block is fixedly installed on the bottom surface of the horizontal section of the connecting frame 9. A square groove is opened on the top surface of the support plate located at the top of the support frame 2 31. The square block is engaged with the square groove, and the square block is fixed to the support plate by fastening bolts 5. The fastening bolts 5 on the support frame 2 31 are set horizontally. The engagement of the square block with the square groove can also play a certain guiding and limiting role, which facilitates the fixing of the fastening bolts 5.

[0030] The front of support frame 1 3 and support frame 2 31 are symmetrically provided with scale lines 13. When adjusting the adjusting bolts 7 on support frame 1 3 and support frame 2 31, the adjustment can be made by referring to the scale lines 13.

[0031] During operation, the turbine body 1 is supported by the support frame 3, the support frame 2, the support component 2, and the connecting frame 9. This not only enhances the stability and balance of the turbine body 1, but also disperses the pressure and protects the support frame 3 and the support frame 2, thereby extending their service life.
