[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that, in the description of the present application, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0040] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0041] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not require further detailed discussion and description in the description of the subsequent drawings.

[0042] Before understanding the embodiments of the present application, it should be noted that in order to simplify the drawings in the present application so that those skilled in the art can clearly understand the specific structure of the disassembly tool proposed in the embodiments of the present application, the threads of all parts (for example, the threaded rod 3, the connecting column 72 and the bolt 51, etc.) are omitted in the drawings of the present application.

[0043] In order to solve the technical problem that the first rotor disk is prone to tilt when the rotor structure is disassembled in the prior art as mentioned in the background technology, the present application proposes an embodiment of a disassembly tool. Specifically, the disassembly tool is used to disassemble the gas turbine rotor structure 1. The rotor structure 1 includes at least a drum shaft 11, a first rotor disk 12 and a second rotor disk 13. The first rotor disk 12 and the second rotor disk 13 are sequentially arranged on the drum shaft 11. It should be noted that in the prior art, the drum shaft 11 may be provided with multiple rotor disks, such as Figure 1 As shown, the embodiment of the present application only describes the disassembly tool proposed in the present application based on the application scenario that the drum shaft 11 has two rotor disks (i.e., the first rotor disk 12 and the second rotor disk 13). It does not mean that the disassembly tool proposed in the present application is only suitable for disassembly of a rotor structure with two rotor disks. The disassembly tool proposed in the present application is suitable for disassembly of a rotor structure with any number of rotor disks. Among them, the first rotor disk 12 should be understood as the rotor disk that currently needs to be removed from the drum shaft 11, and the second rotor disk 13 should be understood as the rotor disk that needs to be removed from the drum shaft 11 last.

[0044] Specifically, the disassembly tool proposed in the present application includes a force-bearing member 2, a chassis 6, a column 5, a driving structure, a plurality of first connecting components 4 and a plurality of second connecting components 7. Specifically, as Figures 3 to 5 As shown, the column 5 is arranged on the chassis 6, and the outer diameter of the column 5 is less than or equal to the inner diameter of the drum shaft 11. When in use, Figure 2 As shown, the drum shaft 11 is directly sleeved on the outside of the column 5 to ensure the stability of the rotor structure 1 during the disassembly process. A plurality of first connecting components 4 are arranged on the force-bearing member 2. When in use, as Figure 2 As shown, each first connection assembly 4 is distributed around the circumference of the drum shaft 11, and each first connection assembly 4 is used to connect with the first rotor disk 12. A plurality of second connection assemblies 7 are arranged on the chassis 6. When in use, as Figure 2 As shown, the second connection components 7 are distributed around the circumference of the drum shaft 11, and each second connection component 7 is used to connect with the second rotor disk 13. The driving structure is used to drive the force bearing member 2 to move along the first direction, which is parallel to the axis direction of the column 5.

[0045] Specifically, during use, Figure 2As shown, the drum shaft 11 in the rotor structure 1 is sleeved on the column 5, each first connecting component 4 is connected to the first rotor disk 12, and each second connecting component 7 is connected to the second rotor disk 13. Finally, the force-bearing member 2 is driven along the first direction by the driving structure so that the force-bearing member 2 gradually moves away from the chassis 6. Furthermore, since the first connecting component 4 is arranged on the force-bearing member 2, and the first connecting component 4 is connected to the first rotor disk 12, if the force-bearing member 2 gradually moves away from the chassis 6, each first connecting component 4 on the force-bearing member 2 can stably separate the first rotor disk 12 and the drum shaft 11. In other words, the disassembly tool proposed in the present application can ensure the stability of the first rotor disk during disassembly through the arrangement of components such as the chassis, the column, the first connecting component and the second connecting component, and can prevent the first rotor disk from tilting during the disassembly process, that is, to prevent the damage of precision components caused by the tilting of the first rotor disk during the disassembly process.

[0046] In the embodiment of the present application, there is no restriction on the shape and structure of the force-bearing member 2. For example, the force-bearing member 2 may be in a block or disc shape. In order to reduce the weight of the force-bearing member 2 and facilitate the user to move the force-bearing member 2, in one embodiment of the present application, Figure 2 and Figure 3 As shown, the force bearing member 2 may be in the form of a support frame.

[0047] It should be clear that in the embodiment of the present application, the first connection component 4 only needs to be able to connect to the first rotor disk 12. For example, the first connection component 4 can be similar to the second connection component 7 described below. In order to facilitate the user to connect the first connection component 4 to the first rotor disk 12, in one embodiment of the present application, Figure 4 As shown, the first connecting assembly 4 is in the shape of a straight rod, one end of the first connecting assembly 4 is hinged to the force bearing member 2, and the other end of the first connecting assembly 4 is bent into a hook shape. When in use, each straight rod-shaped first connecting assembly 4 can be directly hooked to the first rotor disk 12, which is simple and quick to operate.

[0048] As can be seen from the foregoing, in an embodiment of the present application, the first connecting component 4 is movably connected to the first rotor disk 12. It should be noted that in the process of disassembling the first rotor disk 12, if any one of the first connecting components 4 is disconnected from the first rotor disk 12, it will cause uneven force on the first rotor disk 12 and there is a risk of tilting. In order to avoid the straight rod-shaped first connecting component 4 from being disconnected from the first rotor disk 12 during the disassembly of the first rotor disk 12, that is, to avoid the risk of tilting of the first rotor disk 12 due to uneven force. In one embodiment of the present application, the disassembly tool may also include a limit ring 8. When in use, the limit ring 8 is sleeved on the outside of each first connecting component 4 to limit the rotation of each first connecting component 4 around the force-bearing member 2. As Figure 2 As shown, if the first connecting assembly 4 cannot rotate around the force bearing member 2 , the first connecting assembly 4 cannot be separated from the first rotor disk 12 .

[0049] In order to prevent the limiting ring 8 from falling off the first connecting component 4 during use, thereby losing the limiting effect on the first connecting component 4. In one embodiment of the present application, Figure 5 As shown, the first connecting component 4 is also provided with a limiting groove 43. When in use, the limiting ring 8 is inserted into the limiting groove 43, and under the limiting effect of the limiting groove 43, the limiting ring 8 cannot generate relative displacement along the first direction. If the limiting ring 8 cannot generate relative displacement along the first direction, the limiting ring 8 will definitely not fall off from the first connecting component 4.

[0050] In order to make the first connecting assembly 4 applicable to the disassembly of the first rotor disk 12 of different sizes, in one embodiment of the present application, the first connecting assembly 4 includes a first connecting rod 41 and a second connecting rod 42. The first end of the first connecting rod 41 is hinged to the force receiving member 2, the second end of the first connecting rod 41 is hinged to the first end of the second connecting rod 42, and the second end of the second connecting rod 42 is bent into a hook shape. When in use, Figure 5 As shown, it is only necessary to replace the stop ring 8 of the corresponding size according to the first rotor disk 12, without replacing each first connecting assembly 4. Figure 5 As shown, if the first connecting assembly 4 includes a first connecting rod 41 and a second connecting rod 42 , the limiting groove 43 can be provided on the second connecting rod 42 .

[0051] For ease of use, the limiting ring 8 is sleeved on the outside of each first connecting component 4. In one embodiment of the present application, the limiting ring 8 includes at least one arcuate ring, and each arcuate ring can be detachably connected end to end to form the limiting ring 8. It should be noted that in this embodiment, there is no restriction on the manner in which each arcuate ring forms a detachable connection. For example, each arcuate ring can be detachably connected by riveting or bolting. Compared with an integrated ring, a ring with an opening is easier to sleeve on the outside of each first connecting component 4 according to the actual size when in use.

[0052] In an embodiment of the present application, there is no restriction on the connection method between the column 5 and the chassis 6. For example, the column 5 and the chassis 6 can be an integrated structure, or the column 5 and the chassis 6 can be welded. For a large gas turbine, the chassis 6 needs to be designed to be larger, and the production cost is higher. If a corresponding chassis 6 is set for each type of gas turbine, the use cost and maintenance cost are both high. In order to reduce the use cost of the disassembly tool, in an embodiment of the present application, the column 5 and the chassis 6 can form a detachable connection. When in use, there is no need to replace the chassis 6, only the column 5 needs to be replaced according to the type of gas turbine. In other words, many types of gas turbines can share one chassis 6.

[0053] In a specific embodiment of the present application, Figure 7 As shown, the column 5 and the chassis 6 can be detachably connected by a plurality of bolts 51. In order to avoid interference between the bolts 51 and the rotor structure 1 during use, in one embodiment of the present application, the top surface height of each bolt 51 is less than or equal to the top surface height of the chassis 6. Figure 7 As shown, the height difference between the top surface of the chassis 6 and the top surface of the bolt 51 (as shown in Figure 7 The height difference H) shown is greater than or equal to 0. Since the top surface height of each bolt 51 is less than or equal to the top surface height of the chassis 6 , each bolt 51 will definitely not interfere with the rotor structure 1 .

[0054] In the embodiment of the present application, there is no limitation on the shape and structure of the chassis 6, as long as it can stably place the rotor structure 1. For example, the chassis 6 can be a circular plate structure or a square plate structure. In order to further reduce the manufacturing cost of the chassis 6, in one embodiment of the present application, Figure 3 As shown, the chassis 6 can be of hollow design, which can not only reduce the manufacturing cost but also make it easier for the user to take or hoist the chassis 6 .

[0055] It should be clear that in the embodiment of the present application, the second connection component 7 only needs to be able to connect to the second rotor disk 13. For example, the second connection component 7 can be similar to the first connection component 4 mentioned above. In order to enable the second connection component 7 to be stably connected to the second rotor disk 13. In one embodiment of the present application, the chassis 6 is provided with a plug-in slot 61 corresponding to the second connection component 7. The second connection component 7 includes an L-shaped hook 71, a connecting column 72 and a nut 73. Among them, as Figure 5 and Figure 6As shown, the L-shaped hook 71 and the insertion slot 61 form a movable insertion along the first direction. The connecting column 72 is set in the insertion slot 61. The first end of the connecting column 72 is connected to the chassis 6, and the connecting column 72 passes through the L-shaped hook 71. The nut 73 is threadedly connected to the second end of the connecting column 72. When in use, Figure 6 As shown, by rotating the nut 73 to bring the L-shaped hook 71 close to the chassis 6, the L-shaped hook 71 can gradually clamp the second rotor disk 13 ( Figure 6 not shown).

[0056] In order to prevent the L-shaped hook 71 from interfering with the second rotor disk 13 after the nut 73 is loosened, that is, not interfering with the user removing the second rotor disk 13 from the chassis 6, in one embodiment of the present application, the second connecting assembly 7 further includes an elastic member 74, which is disposed in the plug-in slot 61. The elastic member 74 stores elastic potential energy, which is used to make the L-shaped hook 71 have a tendency to pop out of the plug-in slot 61. When in use, if the nut 73 is loosened, the L-shaped hook 71 is pushed out of the plug-in slot 61 under the action of the elastic member 74, and does not contact the second rotor disk 13. If the L-shaped hook 71 does not contact the second rotor disk 13, the L-shaped hook 71 does not interfere with the second rotor disk 13.

[0057] In the embodiment of the present application, the elastic member 74 may be any elastic part, for example, the elastic member 74 may be an elastic metal sheet, or Figure 6 Spring shown.

[0058] In order to make the second connecting assembly 7 applicable to the second rotor disks 13 of different sizes. Figure 3 As shown, the plug-in slots 61 can be arranged in multiple groups along the radial direction of the chassis 6; the distances between the plug-in slots 61 in the same group and the axis of the chassis 6 are the same. In this embodiment, the connecting column 72 forms a detachable connection with the chassis 6. When in use, the second connecting assembly 7 can be moved to the corresponding plug-in slot 61 according to the size of the second rotor disk 13.

[0059] In the embodiment of the present application, the driving structure can be any structure that can drive the force-bearing member 2 to perform linear reciprocating motion. For example, the driving structure can be an electric push rod or a hydraulic push rod. It should be noted that the use of an electric push rod or a hydraulic push rod to drive an object to perform linear reciprocating motion is a mature technology and will not be described in detail here.

[0060] In one embodiment of the present application, Figures 2 to 5As shown, the driving structure may include a threaded rod 3 and a handle 31. The threaded rod 3 is threadedly connected to the force-bearing member 2. The handle 31 is arranged at the second end of the threaded rod 3. When in use, the axis of the threaded rod 3 is aligned with the axis of the column 5, and the first end of the threaded rod 3 is in contact with the force-bearing member 2. The handle 31 is further rotated, and the handle 31 drives the threaded rod 3 to rotate. If the threaded rod 3 rotates, the force-bearing member 2 can move along the axis of the threaded rod 3.

[0061] It should be noted that during use, if the axis of the threaded rod 3 does not coincide with the axis of the column 5, the first rotor disk 12 may be unevenly stressed and tilted. In order to ensure that the axis of the threaded rod 3 always coincides with the axis of the column 5 during use, in one embodiment of the present application, a positioning cylinder 32 is provided at the second end of the threaded rod 3, and the axis of the positioning cylinder 32 coincides with the axis of the threaded rod 3. A positioning circular groove 52 is provided at one end of the column 5 away from the chassis 6, and the axis of the positioning circular groove 52 coincides with the axis of the column 5. The positioning cylinder 32 is adapted to the positioning circular groove 52.

[0062] In this embodiment, if Figure 8 As shown, the positioning cylinder 32 and the positioning groove 52 are adapted to each other, which means that after the positioning cylinder 32 is inserted into the positioning groove 52, the positioning cylinder 32 will not cause a large shake, and when the positioning cylinder 32 rotates, it will not form a large friction force with the positioning groove 52. When in use, the positioning cylinder 32 on the threaded rod 3 is inserted into the positioning groove 52 on the column 5, which can ensure that the axis of the threaded rod 3 always coincides with the axis of the column 5 when in use.

[0063] It should be clear that the embodiment of the disassembly tool proposed in the present application, through the arrangement of components such as the chassis, the column, the first connecting assembly and the second connecting assembly, can ensure the stability of the first rotor disk in the rotor structure during disassembly, and can prevent the first rotor disk from tilting during the disassembly process, that is, avoid the phenomenon of precision components being damaged due to the tilting of the first rotor disk during the disassembly process.

[0064] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
