Description

Technical Field

[0001] This application relates to the field of wind turbine equipment maintenance technology, and in particular to a tooling and device for disassembling the impeller of a wind turbine generator set. Background Technology

[0002] The rotor is the core component of a wind turbine that converts wind energy into mechanical energy; its function is to capture wind energy and convert it into mechanical energy. As an important part of the wind turbine, the rotor needs to be disassembled and hoisted down the tower when replacing major components of the wind turbine (such as the main shaft).

[0003] However, as the wind turbine operates for longer periods, the impeller and main shaft assembly are prone to cold welding under prolonged high torque loads, causing them to stick together and become difficult to separate. Currently, to address this cold welding issue, manufacturers resort to manual hammering or prying, which is not only time-consuming and labor-intensive but also increases the risk of damaging the impeller structure. Utility Model Content

[0004] Therefore, it is necessary to provide a tooling and device for disassembling wind turbine impellers, which are difficult to separate from the main shaft assembly due to the phenomenon of metal cold welding, in order to address the problem in related technologies.

One axial end of the connecting rod is connected to the support and is used for detachable connection with the rotor. The extension rod is located on the side of the support away from the connecting rod and cooperates with the support. The axis of the extension rod is completely coincident with the axis of the connecting rod. The end of the extension rod away from the support is used for cooperation with a lifting device.

[0006] In some embodiments, the surface of the support portion facing away from the connecting rod is provided with a groove, and in the state of engagement between the ejector and the extension rod, one end of the extension rod along the axial direction is disposed in the groove.

[0008] In some embodiments, the extension rod includes a rod body, a protrusion, and a blind hole, with the protrusion and the blind hole respectively disposed at both ends of the rod body along the axial direction; the protrusion engages with a groove, and the blind hole is used to engage with a lifting device.

[0009] In some embodiments, the extension rod also includes a protective layer attached to the outside of the rod body.

[0010] In some embodiments, the ratio of the axial length of the extension rod to the axial length of the connecting rod is 2 to 5.

[0011] In some embodiments, the extension rod is detachably connected to the support.

[0012] In some embodiments, the number of extension rods is multiple.

[0013] In some embodiments, the ejector and at least one extension rod form an ejector assembly, and one ejector assembly is used to cooperate with a lifting device; the wind turbine rotor disassembly fixture includes at least two sets of ejector assemblies.

[0030] Please refer to the following: Figures 1 to 4This application provides a wind turbine rotor disassembly fixture 100, which includes an ejector 10 and an extension rod 20. The ejector 10 includes a support 11 and a connecting rod 12. One axial end of the connecting rod 12 is connected to the support 11 and is used for detachable connection with the rotor. The extension rod 20 is disposed on the side of the support 11 away from the connecting rod 12 and cooperates with the support 11. The axis of the extension rod 20 is completely coincident with the axis of the connecting rod 12. The end of the extension rod 20 away from the support 11 is used for cooperation with a lifting device 200.

[0031] The wind turbine rotor disassembly fixture 100 is a tool for disassembling wind turbine rotors. It aims to solve the problem that after prolonged use, the rotor tends to stick to the main shaft assembly due to cold welding. It replaces the method of using hammers and shovels to strike the rotor in related technologies, and achieves a gentler separation of the rotor from the main shaft assembly, saving labor and time costs, and reducing damage to the rotor during disassembly.

[0032] The ejector 10 is a component in the wind turbine generator impeller disassembly fixture 100 used to cooperate or connect with the impeller. The ejector 10 is connected to the impeller, and the lifting device 200 applies force along the axial direction of the ejector 10, thereby driving the impeller to separate from the main shaft assembly.

[0033] In these embodiments of this application, the ejector 10 includes a support portion 11 and a connecting rod 12. One end of the connecting rod 12 along the axial direction is connected to the support portion 11, and the connecting rod 12 is used for detachable connection with the impeller. The support portion 11 is the base part of the ejector 10, serving as the supporting base for the connecting rod 12 during production, and is used to cooperate with the external lifting device 200 during operation.

[0034] The support part 11 may be, but is not limited to, block or plate, and the shape of the support part 11 may be, but is not limited to, cube, cuboid or cone, as long as it can form a good fit and connection with the lifting device 200 during operation.

[0035] The connecting rod 12 is the component in the ejector 10 that is actually used to cooperate or connect with the impeller. The rod-shaped structure of the connecting rod 12 allows maintenance personnel to extend the connecting rod 12 through a through hole on the wall near the low-speed shaft in the nacelle and make a detachable connection with the impeller.

[0036] The detachable connection between the connecting rod 12 and the impeller can be, but is not limited to, plug-in connection, threaded connection, snap-fit ​​connection, etc., so that the connecting rod 12 can be connected to the impeller by maintenance personnel during maintenance, which can reduce or eliminate the phenomenon of cold welding between the impeller and the main shaft assembly, improve the disassembly efficiency of the impeller, and reduce the damage to the impeller during disassembly.

[0037] In these embodiments of the present application, the connecting rod 12 can be connected to the hub or blades of the impeller. The connection rod 12 can be used to determine the connection based on the hole design on the wall of the nacelle (near the low-speed shaft) and the positional relationship between the impeller and the main shaft assembly, as long as the impeller and the main shaft assembly can be separated by the connecting rod 12.

[0038] The connecting rod 12 is connected to the support part 11. In some embodiments, the connecting rod 12 and the support part 11 are fixedly connected by welding or even integral molding to improve the structural consistency between the connecting rod 12 and the support part 11. In some embodiments, the connecting rod 12 and the support part 11 can also be detachably connected by snap-fit, threaded connection or other means to facilitate the maintenance and replacement of the ejector part 10 itself.

[0039] The extension rod 20 serves to bridge the gap between the ejector 10 and the lifting device 200. For example, in some embodiments, the lifting device 200 needs to be supported by the wall structure in the nacelle to achieve the effect of separating the impeller from the main shaft assembly along the axial direction of the connecting rod 12. In this case, after the ejector 10 is installed with the impeller on the side wall of the nacelle near the low-speed shaft, there may be a gap between it and the lifting device 200, which may prevent the lifting device 200 from connecting with the support 11, or after the lifting device 200 is connected to the support 11, the ejection stroke may be insufficient, making it difficult for the impeller to separate from the main shaft assembly. In this case, the extension rod 20 can be used to bridge the gap between the ejector 10 and the lifting device 200 to achieve the connection between the ejector 10 and the lifting device 200.

[0040] The extension rod 20 cooperates with the support part 11. One possible approach is that there is no connection between the extension rod 20 and the support part 11. In this case, during the installation of the wind turbine rotor disassembly fixture 100, the operator can use an external support bracket to lift the extension rod 20 and make one end of the extension rod 20 contact the support part 11, while the other end is used to cooperate with the lifting device 200. In this way, the force of the lifting device 200 is transmitted to the ejector 10, so that the ejector 10 can drive the rotor to move relative to the main shaft assembly.

[0041] The axis of the extension rod 20 is completely aligned with the axis of the connecting rod 12, so that the output shaft of the lifting device 200, the axis of the connecting rod 12 and the axis of the extension rod 20 are in a straight line. In this way, when the lifting device 200 is working, the stability of the entire ejection system can be increased, the risk of assembly failure caused by axis deviation can be reduced, and the reliability can be improved.

[0042] In these embodiments of the present application, the extension rod 20 can be used in conjunction with a lifting device 200 such as a jack to gently separate the impeller from the main shaft assembly without having to knock or pry the impeller, thus reducing damage to the impeller and extending its service life.

[0043] According to the wind turbine rotor disassembly fixture 100 provided in the embodiments of this application, the ejector 10 includes a support 11 and a connecting rod 12, and the connecting rod 12 is used for detachable connection with the rotor. An extension rod 20 is set on the side of the support 11 away from the connecting rod 12, and the end of the extension rod 20 away from the support 11 is used to cooperate with the lifting device 200. During the disassembly of the rotor, the connecting rod 12 can be used to smoothly connect with the rotor, and then the lifting device 200 can be used to separate the rotor from the main shaft assembly. This can reduce the damage to the rotor during the disassembly process and save labor and time costs.

[0044] In some embodiments, the support portion 11 has a groove 111 on the surface opposite to the connecting rod 12. When the ejector 10 and the extension rod 20 are engaged, one end of the extension rod 20 along the axial direction is disposed in the groove 111.

[0045] In these embodiments of the present application, one end of the extension rod 20 along the axial direction is set in the groove 111, which can improve the assembly accuracy between the extension rod 20 and the ejector 10, reduce the time required for positioning the extension rod 20 during installation, and further improve the assembly efficiency of the wind turbine rotor disassembly fixture 100.

[0046] In other words, during the production and molding stage of the ejector 10, the groove 111 in the support 11 can be positioned on the axis of the connecting rod 12. In this way, when the extension rod 20 is assembled with the ejector 10, the axis of the extension rod 20 and the axis of the connecting rod 12 can be completely coincident. At the same time, the groove wall of the groove 111 can also correct the force transmission direction of the extension rod 20, reduce the risk of angular deviation between the extension rod 20 and the ejector 10 during operation, and further improve the overall reliability of the ejection system.

[0047] It is understood that the cross-sectional shape of the groove 111 can be consistent with the cross-sectional shape of the extension rod 20. In these embodiments of this application, the cross-sectional shape of the groove 111 and the cross-sectional shape of the extension rod 20 can be set to be circular, rectangular or triangular, which can be selected according to the actual needs on site.

[0048] In some embodiments, the groove 111 includes a bottom wall 1111 and a side wall 1112. One end of the side wall 1112 facing away from the bottom wall 1111 is the opening 1113 of the groove 111. An angle is formed between the side wall 1112 and the bottom wall 1111. The cross-sectional area of ​​the groove 111 gradually increases along the direction from the bottom wall 1111 to the opening 1113.

[0049] The angle formed between the sidewall 1112 and the bottom wall 1111 of the groove refers to the fact that the sidewall 1112 of the groove is a sloping structure, which provides a guiding effect for the installation of the extension rod 20 when it is assembled with the ejector 10, and further reduces the installation accuracy requirements of the extension rod 20 during assembly.

[0050] Along the direction from the bottom wall 1111 to the opening 1113, the cross-sectional area of ​​the groove 111 gradually increases, which is intended to gradually guide the axis of the extension rod 20 and the axis of the connecting rod 12 to a straight line during assembly. This provides a guiding function for the installation of the extension rod 20 and further reduces the installation accuracy requirements of the extension rod 20 during assembly.

[0051] In some embodiments, the extension rod 20 includes a rod body portion 21, a protrusion portion 22, and a blind hole portion 23. The protrusion portion 22 and the blind hole portion 23 are respectively disposed at both ends of the rod body portion 21 along the axial direction. The protrusion portion 22 cooperates with the groove 111, and the blind hole portion 23 is used to cooperate with the lifting device 200.

[0052] The extension rod 20 includes a rod body 21, a protrusion 22, and a blind hole 23. This means that the extension rod 20 has a protrusion structure, namely the protrusion 22, at both ends along the axial direction. The protrusion 22 can be used to cooperate with the groove 111 on the support part 11.

[0053] A blind hole, or blind hole portion 23, is provided at the other end. In this way, in some embodiments, the blind hole portion 23 can be used to cooperate or connect with the lifting device 200; in some embodiments, due to the axial length of the extension rod 20, it may be necessary to provide multiple extension rods 20 between the ejector 10 and the lifting device 200 to meet the spacing requirements between the ejector 10 and the lifting device 200. In this case, adjacent extension rods 20 can also be connected by the cooperation of the protrusion 22 and the blind hole portion 23.

[0054] In these embodiments of the present application, the blind hole portion 23 may also be provided with a beveled structure to reduce the assembly accuracy requirements between adjacent extension rods 20 or between the extension rod 20 and the output shaft of the lifting device 200.

[0055] In some embodiments, the extension rod 20 further includes a protective layer 24 attached to the outside of the rod body portion 21.

[0056] In these embodiments of the present application, the protective layer 24 can be an anti-corrosion coating. In this case, the protective layer 24 is mainly used to provide anti-corrosion effect for the extension rod 20, reduce the erosion of the extension rod 20 by external moisture or other corrosive substances, and improve the service life and structural strength of the extension rod 20.

[0057] In some embodiments, the protective layer 24 may be made of elastic materials such as rubber or plastic. In this case, the impact of bumps on the extension rod 20 during use can be mitigated. At the same time, the protective layer 24 can also reduce the risk of the extension rod 20 coming into contact with the human body during installation, disassembly, and transportation, and can reduce the risk of maintenance personnel being bumped or injured by the extension rod 20 when installing, disassembling, or transporting the extension rod 20.

[0058] The protective layer 24 is connected to the outside of the rod body 21. In possible implementations, the protective layer 24 can be fixedly connected to the rod body 21 by means of bonding, welding, injection molding, etc. In some embodiments, the protective layer 24 and the rod body 21 can also be detachably connected by means of snap-fit, connectors (screws, bolts, etc.) to facilitate the replacement or disassembly and maintenance of the protective layer 24.

[0059] In some embodiments, the ratio of the axial length of the extension rod 20 to the axial length of the connecting rod 12 is 2 to 5.

[0060] In other words, the axial length of the extension rod 20 can be 2 to 5 times the axial length of the connecting rod 12. As a result, in the wind turbine rotor disassembly fixture 100, the length of the ejector 10 is smaller, which is beneficial for maintenance personnel to cooperate or connect the ejector 10 with the rotor and facilitates operation. The longer extension rod 20 is more conducive to bridging the gap between the ejector 10 and the lifting device 200.

[0061] Meanwhile, the separate design of the extension rod 20 and the ejector 10 facilitates the handling of the wind turbine rotor disassembly tool 100 itself, making it convenient for maintenance personnel to carry it into the nacelle.

[0062] In some embodiments, the extension rod 20 is detachably connected to the support portion 11.

[0063] One possible implementation is that the extension rod 20 has a first threaded structure on the protrusion 22 and a second threaded structure on the groove 111, in which case the extension rod 20 and the protrusion 22 can be threadedly connected; or, the groove 111 has a buckle and the protrusion 22 has a locking block that cooperates with the buckle, so that when the extension rod 20 is connected to the support 11, the buckle and the locking block cooperate with each other to achieve a detachable connection between the extension rod 20 and the support 11.

[0064] This configuration improves the stability of the connection between the extension rod 20 and the ejector 10, eliminating the need for a separate support structure for the extension rod 20 and further enhancing the efficiency of maintenance personnel in disassembling and assembling the impeller.

[0065] In some embodiments, the number of extension rods 20 is multiple.

[0066] It should be noted that different lengths can be set among the multiple extension rods 20, so that when maintaining wind turbine generators of different sizes, maintenance personnel can choose extension rods 20 of different lengths, reducing the need to wear extension rods 20 and reducing the difficulty of maintenance work.

[0067] In some embodiments, extension rods 20 of different lengths and sizes may be used in combination to accommodate different spacing conditions between the ejector 10 and the lifting device 200.

[0068] In some embodiments, the ejector 10 and at least one extension rod 20 form an ejection assembly (not labeled), and one ejection assembly is used to cooperate with a lifting device 200; the wind turbine rotor disassembly fixture 100 includes at least two sets of ejection assemblies.

[0069] In these embodiments of the present application, at least two sets of ejection components are used together in the disassembly of the impeller, which helps to push the impeller away from the main shaft assembly evenly along its axial direction, and can also reduce damage to the impeller during disassembly.

[0070] In some embodiments, the number of ejector components can be the same as the number of fans on the impeller. One ejector component acts as one fan on the impeller, and all ejector components work together, which helps to improve the disassembly efficiency of the impeller.

[0071] This application also provides a wind turbine rotor disassembly device, which includes a lifting device 200 and a wind turbine rotor disassembly fixture 100 as provided in any of the foregoing embodiments.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
