Description

Technical Field

[0001] This utility model relates to the field of rotor positioning and transfer technology, specifically, a gas turbine rotor transfer tooling. Background Technology

[0002] The gas turbine rotor is the core component of the gas turbine, and it is expensive, structurally precise, and heavy. During manufacturing, maintenance, and storage, the rotor needs to be frequently hoisted, stored, and transferred within the plant. The traditional method is to place the rotor directly on a V-shaped iron block or a simple support, which has the following drawbacks: (1) The fixing is not secure, and it is easy to roll or move axially, posing a safety hazard of tipping over and injuring people; (2) There is a lack of effective buffering and protection measures, and the rotor surface (especially critical parts such as bearing journals and gear meshing surfaces) is easily damaged, scratched, or deformed due to rigid contact or collision; (3) Transfer is extremely inconvenient, usually requiring multiple hoisting operations with the help of overhead cranes and forklifts, which is cumbersome, inefficient, and poses a risk of secondary collisions. Therefore, there is an urgent need for a special tooling equipment that integrates storage, protection, and transfer functions to ensure the safety and ease of operation of the rotor. Utility Model Content

[0003] The purpose of this invention is to provide a gas turbine rotor transfer fixture to solve the problems of easy movement and wear of existing gas turbine rotors during storage and transfer.

[0004] To solve the above problems, the present invention adopts the following technical means: A gas turbine rotor transfer fixture, comprising: The moving mechanism comprises a base plate and a lockable universal wheel mounted on the bottom surface of the base plate as a moving part. A pair of support mechanisms are provided on the top surface of the substrate and are symmetrically arranged. Each of them is provided with a clamping mechanism at its top end, and each of the two clamping mechanisms is provided with a coaxially arranged positioning channel. A stop mechanism is provided on the outside of one of the support mechanisms, and a stop part is constructed at the top. The stop part is constructed with a threaded rod coaxially arranged with the positioning channel. The threaded end of the threaded rod faces the positioning channel, and the threaded rod is positioned and connected to the main body of the stop mechanism.

[0005] Preferably, a lifting plate is also installed on the top surface of the substrate, and the lifting plate is provided with through holes for positioning.

[0006] Furthermore, the support mechanism includes a straight rod installed on the top surface of the substrate, and support rods with their top ends inclined toward the top end of the straight rod are respectively provided on the front and rear sides of the straight rod. The bottom end of the support rod is connected to the top surface of the substrate, and a bearing platform is installed at the top end of the straight rod. The top end of the support rod is connected to the bottom surface of the bearing platform, and the clamping mechanism is installed on the top surface of the bearing platform.

[0007] Furthermore, the clamping mechanism includes a bearing plate installed at the top of the support mechanism. The top of the bearing plate is constructed with a first arc groove, and an arc plate is detachably installed on the top surface of the bearing plate. The arc surface of the arc plate is configured as a second arc groove with the opening facing downward. The first arc groove and the second arc groove are spliced ​​together to form the positioning channel for clamping the shaft end of the rotor.

[0008] Furthermore, rubber pads are attached and installed in the first arc groove and the second arc groove respectively.

[0009] Furthermore, the stopping mechanism includes a mounting plate installed on the outer side wall of the support mechanism. A positioning plate is installed on the top surface of the mounting plate. A horizontal threaded rod is installed on the top end of the positioning plate. The positioning part of the threaded rod slides through the positioning plate. Two clamping nuts are threadedly installed on the positioning part of the threaded rod. The positioning plate is clamped between the two clamping nuts.

[0010] Furthermore, a first reinforcing rib is installed at the corner where the bottom side of the positioning plate connects to the mounting plate, and a second reinforcing rib is installed at the vertically extending position of the positioning plate.

[0011] This utility model has the following beneficial effects during use: When storing or transferring a gas turbine rotor, the positioning channels of the clamping mechanism are opened. The rotor shaft ends are then placed into the open positioning channels of the clamping mechanism, and the channels are sealed, clamping the rotor shaft ends into the two positioning channels respectively. Afterward, the threaded rod is aligned with the coaxial threaded hole on the rotor shaft end. By rotating the threaded rod, it is inserted into the rotor shaft end, and then the threaded rod is positioned and connected to the main body of the stop mechanism, thus stopping the rotor. Under the combined action of the clamping and support mechanisms, even during transfer, the rotor will not experience axial movement or rotation around its axis. This effectively avoids wear between the rotor shaft end and the clamping mechanism caused by rotor rotation and movement, greatly improving the stability and integrity of the rotor during storage and transfer.

[0021] Please refer to Figure 1 and Figure 2 As shown, a gas turbine rotor transfer fixture includes: The moving mechanism comprises a base plate 1 and a lockable universal wheel mounted on the bottom surface of the base plate 1 as a moving part 2; A pair of support mechanisms are provided on the top surface of the substrate 1 and are symmetrically arranged. Each of them is provided with a clamping mechanism at its top, and the two clamping mechanisms are respectively provided with a coaxially arranged positioning channel. A stop mechanism is provided on the outside of one of the support mechanisms, and a stop part is constructed at the top. The stop part is constructed with a threaded rod 3 coaxially arranged with the positioning channel. The threaded end of the threaded rod 3 faces the positioning channel, and the threaded rod 3 is positioned and connected to the main body of the stop mechanism.

[0022] In this way, when the gas turbine rotor needs to be stored or transferred, the positioning channels of the clamping mechanism are kept open, and the two sides of the rotor shaft end are placed in the open positioning channels of the clamping mechanism. Then, the positioning channels are sealed, so that the two sides of the rotor shaft end are clamped in the two positioning channels respectively. After completion, the threaded rod 3 is aligned with the coaxial threaded hole of the rotor shaft end. By rotating the threaded rod 3, it is inserted into the rotor shaft end. Then, the threaded rod 3 is positioned and connected to the main body of the stop mechanism, thereby stopping the rotor. Under the dual action of the clamping mechanism and the support mechanism, even during the transfer process, the rotor will not experience axial movement or rotation around the axis. This effectively avoids wear between the rotor shaft end and the clamping mechanism caused by rotor rotation and axial movement, greatly improving the stability and integrity of the rotor during storage and transfer.

[0023] To facilitate movement, a lifting plate 4 is also installed on the top surface of the substrate 1, and the lifting plate 4 is provided with through holes for positioning.

[0024] In this way, in addition to transferring the rotor by pushing, the hoisting mechanism can also be used to hoist the entire tooling and rotor by connecting the hoisting part of the hoisting mechanism with the through hole of the hoisting plate 4. Even if shaking occurs during the hoisting process, the rotor can be prevented from rotating or shifting due to the clamping and stopping mechanisms, thus ensuring the stability and integrity of the hoisting process.

[0025] Furthermore, the support mechanism includes a straight rod 5 installed on the top surface of the substrate 1. Support rods 6 with their top ends inclined towards the top of the straight rod 5 are respectively provided on the front and rear sides of the straight rod 5. The bottom end of the support rod 6 is connected to the top surface of the substrate 1. A bearing platform 7 is installed on the top of the straight rod 5. The top end of the support rod 6 is connected to the bottom surface of the bearing platform 7. The clamping mechanism is installed on the top surface of the bearing platform 7.

[0026] Furthermore, the clamping mechanism includes a bearing plate 8 installed at the top of the support mechanism. The top of the bearing plate 8 is constructed with a first arc groove 9. An arc plate 10 is detachably installed on the top surface of the bearing plate 8. The arc surface of the arc plate 10 is configured as a second arc groove 11 with the opening facing downward. The first arc groove 9 and the second arc groove 11 are spliced ​​together to form the positioning channel for clamping the shaft end of the rotor.

[0027] Thus, when the bearing plate 8 is separated from the arc plate 10, the positioning channel is in an open state. When the arc plate 10 and the bearing plate 8 are in close contact through bolts, so that the first arc groove 9 and the second arc groove 11 are spliced ​​to form a complete circular channel, the positioning channel is in a clamped state, and the shaft end of the rotor is locked by the clamping of the first arc groove 9 and the second arc groove 11.

[0028] Furthermore, rubber pads 12 are respectively attached and installed in the first arc groove 9 and the second arc groove 11.

[0029] In this way, the rubber pad 12 not only further avoids hard contact between the rotor shaft end and the inner wall of the positioning channel, but also allows the relatively fixed positioning channel to stably clamp rotor shaft ends of different diameters by removing and installing rubber pads 12 of different thicknesses.

[0030] Furthermore, the stopping mechanism includes a mounting plate 13 installed on the outer wall of the support mechanism. A positioning plate 14 is installed on the top surface of the mounting plate 13. A horizontal threaded rod 3 is installed on the top end of the positioning plate 14. The positioning part of the threaded rod 3 slides through the positioning plate 14. Two clamping nuts 15 are threadedly installed on the positioning part of the threaded rod 3. The positioning plate 14 is clamped between the two clamping nuts 15.

[0031] Thus, when the threaded rod 3 is rotated, the two deposit nuts are loosened, allowing the threaded rod 3 to rotate normally, thereby enabling it to be inserted into or removed from the rotor shaft end. After the threaded rod 3 is inserted, the two deposit nuts are used to clamp the positioning plate 14, thereby achieving a positioning connection between the threaded rod 3 and the positioning plate 14, and thus stopping the rotor shaft end. This prevents the rotor from axially shifting or rotating around its axis during transfer.

[0032] Furthermore, a first reinforcing rib 16 is installed at the corner where the bottom side of the positioning plate 14 connects to the mounting plate 13, and a vertically extending second reinforcing rib 17 is installed at the vertically extending position of the positioning plate 14.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
