[0047] As a kind of electric power equipment that converts wind energy into mechanical energy and then into electrical energy, wind turbines can capture wind energy with blades, convert wind energy into mechanical energy, and then use generators to convert mechanical energy into electrical energy. As people pay more and more attention to the environment, wind turbines are getting more and more attention. Compared with land, wind resources at sea are more abundant, the advantages of offshore wind power projects are becoming more and more obvious, and the capacity of offshore wind turbines is also becoming more and more obvious.

[0048] As the capacity of wind turbines continues to increase, the height and impeller diameter of wind turbines are also getting larger and larger. The installation equipment used for blade installation (such as wind power installation ships) can no longer meet the requirements of the simultaneous installation of multiple blades. At present, the blades in wind turbines are usually installed as single blades. Therefore, the turning device plays an important role in the blade installation process.

[0049] The winch device in the wind turbine generator set is connected to the rotor of the generator. Since the rotating shaft of the generator rotor is at a certain angle to the horizontal direction, the winch device must be installed on the generator at an angle during installation, which makes the installation of the winch device more difficult and the installation speed is slower.

[0050] In order to reduce the installation difficulty of a winch device and improve the installation speed, the present application provides a winch device, which includes a main body and a guide mechanism, wherein the rotating structure in the main body is rotatably connected to a bracket, the bracket is used to be connected to the stator of a generator, the rotating structure is used to be connected to the rotor of the generator, and the guide mechanism includes a guide, a locking member and a connecting member, the connecting member is used to be connected to the stator, the guide is rotatably connected to the connecting member, and the locking member is movably connected to the guide member to drive the bracket to be locked on the connecting member. Since the guide member in the winch device is rotatably connected to the connecting member, and the locking member connected to the guide member can drive the bracket to be locked on the connecting member, when the winch device is installed on the generator, the connecting member quickly corresponds to the connection position of the stator by rotating relative to the guide member, and the locking member can drive the bracket to be locked on the connecting member, so that the bracket of the winch device can be conveniently and quickly locked on the stator of the generator, and the winch device and the generator can be quickly positioned, thereby reducing the subsequent installation difficulty of the winch device and improving the installation speed.

[0051] The following is a further description of the winch device, the installation method of the winch device and the technical solution of the wind turbine generator set provided in the specific implementation manner of the present application.

[0052] Some embodiments of the present application provide a turning device for a generator, such as Figure 1 As shown, the turning device includes a main body 1 and a guide mechanism 2. The main body 1 includes a rotating structure 11 and a bracket 12. The rotating structure 11 is rotatably connected to the bracket 12. The rotating structure 11 is used to connect to the rotor of the generator, and the bracket 12 is used to connect to the stator of the generator. Figure 2 As shown, the guide mechanism 2 includes a guide member 21, a locking member 22 and a connecting member 23. The connecting member 23 is used to connect to the stator. The connecting member 23 is rotatably connected to the guide member 21. The locking member 22 is movably connected to the guide member 21 to drive the bracket 12 to be locked to the connecting member 23.

[0053] The main body 1 may refer to the main structure of the turning device, which includes a rotating structure 11 and a bracket 12. The rotating structure 11 may be a structure in the main body 1 that can rotate around its own axis, which is rotatably connected to the bracket 12 and can rotate around its own axis on the bracket 12.

[0054] like Figure 3As shown, the rotating structure 11 may include a connecting rotating disk 111 and a gear ring 112, the gear ring 112 is rotatably connected to the bracket 12, and the connecting rotating disk 111 is connected to the gear ring 112 and can rotate with the gear ring 112. Exemplarily, the central axis of the connecting rotating disk 111 is configured to coincide with the central axis of the gear ring 112, so that the connecting rotating disk 111 can be conveniently positioned and connected to the gear ring 112. In some embodiments, the gear ring 112 is rotatably connected to the bracket 12 through a bearing, so that the gear ring 112 rotates smoothly, so that the rotating structure 11 can smoothly rotate on the bracket 12.

[0055] By connecting the rotating structure 11 capable of rotating on the bracket 12 to the rotor of the generator, the rotating structure 11 in the winching device can rotate synchronously with the rotor, so that the rotating structure 11 in the winching device can drive the rotor to rotate, thereby driving the impeller to rotate, making it convenient for the blades to be installed individually.

[0056] The bracket 12 may be a frame structure on the main body 1 of the winch device, which is used to fix the main body 1 to other structures to achieve fixed connection of the main body 1 of the winch device. By connecting the bracket 12 to the stator of the generator, the main body 1 of the winch device can be fixedly connected to the stator of the generator, thereby achieving connection of the winch device to the generator.

[0057] The guiding mechanism 2 can be a mechanism for guiding the main body 1 of the turning device during the installation on the generator. Under its own guiding action, it can lock the bracket 12 of the turning device to the stator of the generator, thereby realizing the positioning of the turning device and the generator, which can effectively reduce the subsequent installation difficulty of the turning device and improve the installation speed.

[0058] The guide member 21 can be a member that can guide the movement of the bracket 12 when the guide mechanism 2 locks the bracket 12. The locking member 22 can be a member in the guide mechanism 2 for locking the bracket 12 on the connecting member 23, which is movably connected to the guide member 21, and the locking member 22 can drive the bracket 12 to move along the guide member 21 to lock it on the connecting member 23. The connecting member 23 can be a member in the guide mechanism 2 for connecting with the stator, which is rotatably connected to the guide member 21, so that when the winch device is connected to the generator, the connecting member 23 can quickly correspond to the connection position of the stator of the generator by rotating relative to the guide member 21, which is conducive to reducing time consumption and improving efficiency.

[0059] In some embodiments, the guide member 21 may include a guide rod having a preset length, so that the locking member 22 can drive the bracket 12 to move along the guide member 21, so that the bracket 12 continues to approach the connecting member 23 to achieve locking with the connecting member 23.

[0060] In the above structure, since the guide member 21 and the connecting member 23 in the winch device are rotatably connected, and the locking member 22 connected to the guide member 21 can drive the bracket 12 to be locked to the connecting member 23, when the winch device is installed on the generator, the connecting member 23 can be quickly connected to the corresponding connection position of the stator by rotating relative to the guide member 21, and the locking member 22 can drive the bracket 12 to be locked to the connecting member 23, so that the bracket 12 of the winch device can be conveniently and quickly locked on the stator of the generator, thereby realizing the positioning of the winch device and the generator, reducing the difficulty of subsequent installation of the winch device, and improving the installation speed.

[0061] In some embodiments, the winch device further includes a driving mechanism, which is used to drive the rotating structure 11 to rotate, so that the winch device can drive the rotor of the generator to rotate. The driving mechanism includes a driver (not shown in the figure) and a gear 5, the driver is connected to the bracket 12, the gear 5 is transmission-connected to the output shaft of the driver, and the gear 5 is meshed with the ring gear 112, so that the driver can drive the ring gear 112 to rotate through the gear 5 to drive the rotor of the generator.

[0062] In some embodiments, a guide hole 121 is provided on the bracket 12, and the guide member 21 is passed through the guide hole 121. The locking member 22 and the connecting member 23 are respectively located on both sides of the bracket 12 along the axial direction of the guide hole 121, and the locking member 22 is movably connected to the guide member 21 along the axial direction to clamp the bracket 12 between the connecting member 23 and the locking member 22.

[0063] The guide hole 121 may be a hole-shaped structure provided on the bracket 12, which penetrates the bracket 12 along the thickness direction of the bracket 12. By inserting the guide member 21 into the guide hole 121, the guide member 21 can be connected to the bracket 12 through the guide hole 121. By respectively providing the locking member 22 and the connecting member 23 on both sides of the bracket 12 along the axial direction of the guide hole 121, and making the locking member 22 movably connected to the guide member 21 along the axial direction, when the locking member 22 approaches the connecting member 23 along the axial direction of the guide member 21, the bracket 12 can be clamped between the connecting member 23 and the locking member 22, so as to achieve the locking of the bracket 12 relative to the connecting member 23, thereby facilitating the positioning of the bracket 12 on the stator of the generator.

[0064] In some embodiments, along the radial direction of the guide hole 121 , the size of the guide member 21 is smaller than the size of the guide hole 121 .

[0065] Along the radial direction of the guide hole 121, the size of the guide member 21 is smaller than the size of the guide hole 121. The radial size of the guide member 21 is smaller than the radial size of the guide hole 121, so that the guide member 21 inserted into the guide hole 121 has a certain amount of movable margin in the radial direction of the guide hole 121, and the connecting member 23 connected to the guide member 21 also has a corresponding movable margin, so that the corresponding connection position of the connecting member 23 and the stator is more convenient.

[0066] In some embodiments, a plurality of first supports 122 are disposed on the bracket 12 . The plurality of first supports 122 are arranged at intervals, and each first support 122 is provided with a guide hole 121 .

[0067] The first support 122 may be a seat structure disposed on the bracket 12 . By disposing the guide hole 121 on the first bracket 12 , damage to the structure of the bracket 12 caused by the disposed guide hole 121 is reduced, which is beneficial for the bracket 12 to have good structural strength.

[0068] By arranging a plurality of first supports 122 with guide holes 121 on the bracket 12, the plurality of first supports 122 are arranged at intervals, so that the guide mechanism 2 can be selectively connected to one of the plurality of first supports 122 through the guide member 21. The guide mechanism 2 can adapt to the connection position of the stator of different types of generators by selecting to be connected to different first supports 122, which is beneficial to improving the adaptability of the winch device.

[0069] In some embodiments, the locking member 22 includes a screwing portion 221 and a resisting portion 222 . The resisting portion 222 is sleeved on the outside of the guide member 21 . The screwing portion 221 is connected to the guide member 21 via threads. The resisting portion 222 is located on a side of the screwing portion 221 close to the bracket 12 .

[0070] The screwing portion 221 may be a component of the locking member 22 for screwing the locking member 22. The screwing portion 221 is connected to the guide member 21 by a thread, so that the screwing portion 221 can move along the axial direction of the guide member 21 by screwing. The abutting portion 222 may be a component of the locking member 22 for contacting with and abutting the bracket 12. The abutting portion 222 is sleeved on the outer side of the guide member 21 and connected to the screwing portion 221, and can move under the drive of the screwing portion 221. By arranging the abutting portion 222 on the side of the screwing portion 221 close to the bracket 12, the abutting portion 222 can abut the bracket 12 under the drive of the screwing portion 221, and the bracket 12 is pressed against the connecting plate 232, so as to achieve the clamping and locking of the bracket 12.

[0071] Exemplarily, the screwing portion 221 is provided with a threaded hole, and the outer peripheral surface of the guide member 21 is provided with an external thread matching the threaded hole, so that the screwing portion 221 can move along the axial direction of the guide member 21 by screwing.

[0072] In some embodiments, the guide mechanism 2 includes a rotating shaft 24 , and the guide member 21 is rotatably connected to the connecting member 23 via the rotating shaft 24 .

[0073] The rotating shaft 24 may be a member for rotatably connecting the connecting member 23 and the guide member 21. The guide member 21 is rotatably connected to the connecting member 23 via the rotating shaft 24, so that the connecting member 23 can quickly adjust the corresponding position with the stator by rotating relative to the guide member 21, so that the connecting member 23 can quickly correspond to the connection position of the stator.

[0074] In some embodiments, the rotating shaft 24 can be fixedly connected to the guide member 21 , and the connecting member 23 can be rotatably connected to the rotating shaft 24 , so that the connecting member 23 and the guide member 21 can rotate relative to each other under the action of the rotating shaft 24 .

[0075] Exemplarily, the rotating shaft 24 may be formed by a pin or a bolt, and those skilled in the art may select the type of component forming the rotating shaft 24 according to actual conditions.

[0076] In some embodiments, the connecting member 23 includes a second support 231 and a connecting plate 232 connected to each other, the rotating shaft 24 is rotatably connected to the second support 231, and the connecting plate 232 is provided with a plurality of connecting holes 2321, and the plurality of connecting holes 2321 are connected to the stator through connecting bolts.

[0077] The second support 231 may be a seat structure in the connecting member 23, which is used to be rotatably connected to the rotating shaft 24. The connecting plate 232 may be a plate-shaped structure in the connecting member 23, which is used to be connected to the stator. The connecting plate 232 with a plate-shaped structure is used to connect to the stator, so that the connecting member 23 has a larger contact area with the stator, which is conducive to improving the stability of the connection between the connecting member 23 and the stator.

[0078] In some embodiments, the connecting plate 232 is provided with a connecting hole 2321, and the connecting hole 2321 is connected to the stator through a connecting bolt, so that the connecting plate 232 is connected to the stator. Exemplarily, there are multiple connecting holes 2321 on the connecting plate 232, and the multiple connecting holes 2321 are spaced and evenly arranged on the connecting plate 232. By connecting the evenly distributed multiple connecting holes 2321 to the stator through the connecting bolts, the force borne by the connecting member 23 can be evenly dispersed, reducing the concentration of the force, which is conducive to improving the force condition of the connecting member 23.

[0079] In some embodiments, the turning device further includes a first positioning mechanism and a second positioning mechanism, the bracket 12 is connected to the stator through the first positioning mechanism, and the rotating structure 11 is connected to the rotor through the second positioning mechanism.

[0080] The first positioning mechanism may be a mechanism for positioning the bracket 12 and the stator of the generator, and the second positioning mechanism may be a mechanism for positioning the rotating structure 11 and the rotor of the generator. After the bracket 12 is relatively positioned with the stator by using the first positioning mechanism, the bracket 12 is fixedly connected with the stator, so that the bracket 12 is not easily misaligned when connected with the stator, and the connection is more convenient; after the rotating structure 11 is relatively positioned with the rotor by using the second positioning mechanism, the rotating structure 11 is fixedly connected with the rotor, so that the rotating structure 11 is not easily misaligned when connected with the rotor, and the connection is more convenient.

[0081] In some embodiments, the first positioning mechanism includes a first positioning pin 31 and a first positioning member 32 connected to each other. The bracket 12 is provided with a first positioning hole 123. The first positioning pin 31 is inserted into the first positioning hole 123. The first positioning member 32 is used to connect to the stator.

[0082] The first positioning pin 31 and the first positioning member 32 are different components in the first positioning mechanism, and the two are connected to each other. The first positioning pin 31 is inserted into the first positioning hole 123 set on the bracket 12, and the first positioning member 32 is connected to the stator, so that the bracket 12 can be positioned on the stator through the first positioning mechanism.

[0083] In some embodiments, the second positioning mechanism includes a second positioning pin 41 . A second positioning hole 1111 is provided on the rotating structure 11 . The second positioning pin 41 passes through the second positioning hole 1111 and is used to connect with the rotor.

[0084] The second positioning pin 41 passes through the second positioning hole 1111 and can extend from the second positioning hole 1111. By connecting the second positioning pin 41 extending from the second positioning hole 1111 to the rotor, the rotating structure 11 can be positioned on the rotor through the second positioning mechanism.

[0085] The present application also provides a method for installing a winch device, which is used to install the winch device provided by the above technical solution on a generator, such as Figure 4 As shown, the installation method of the turning device includes the following steps:

[0086] S1, a transfer step, transferring the main body 1 connected with the guide mechanism 2 to the generator.

[0087] In the above steps, the main body 1 connected with the guide mechanism 2 is transported to the generator so that the winch device can be positioned on the generator later.

[0088] In some embodiments, the main body 1 connected with the guide mechanism 2 can be hoisted to the end of the generator by a hoisting device such as a crane, so that the winch device is level with the generator.

[0089] In some embodiments, after the main body 1 connected with the guide mechanism 2 is transported to the generator, the following steps may be performed:

[0090] S11, adjusting the position of the bracket 12 in the main body 1.

[0091] That is to say, after the winch device is hoisted to the end of the generator in step S1, the position of the winch device can also be adjusted so that the guide mechanism 2 can be as close to the connection position of the stator of the generator as possible, so as to reduce the difficulty of subsequent connection between the guide mechanism 2 and the stator of the generator.

[0092] It is understandable that the position of the bracket 12 can be adjusted by making multiple fine adjustments to the position of the winch device using a hoisting device such as a crane, so that the guide mechanism 2 can be as close as possible to the connection position of the stator of the generator.

[0093] S2. Corresponding step: rotating the connecting member 23 of the guide mechanism 2 relative to the guide member 21 so that the connecting member 23 corresponds to the connecting position of the stator of the generator.

[0094] In the above steps, the connector 23 in the guide mechanism 2 is rotated relative to the guide member 21, so that the connector 23 can quickly adjust its direction to face the connection position of the stator of the generator, so as to facilitate the subsequent connection between the connector 23 and the stator of the generator.

[0095] S3 , a locking step, connecting the connecting piece 23 to the connecting position of the stator, and using the locking piece 22 of the guide mechanism 2 to lock the bracket 12 of the main body 1 to the connecting piece 23 .

[0096] In the above steps, after the connecting piece 23 is connected to the connecting position of the stator, the bracket 12 is locked to the connecting piece 23 by the locking piece 22 of the guide mechanism 2, so that the bracket 12 can be locked to the stator of the generator under the action of the guide mechanism 2, so that the winch device is limited to the end of the generator.

[0097] In some embodiments, as in the winch device provided by the aforementioned technical solution, a guide hole 121 is provided on the bracket 12, the guide member 21 is passed through the guide hole 121, the locking member 22 is threadedly connected to the guide member 21, and the locking member 22 and the connecting member 23 are respectively located on both sides of the bracket 12 along the axial direction of the guide hole 121.

[0098] like Figure 5 As shown, the above step S3 may include the following steps:

[0099] S31, connecting the connecting piece 23 to the connecting position of the stator.

[0100] Exemplarily, a connection hole 2321 is provided on the connection member 23. The connection member 23 and the stator can be connected to the stator by connecting bolts passing through the connection hole 2321, so that the connection member 23 and the stator are detachably connected.

[0101] S32, moving the main body 1 relative to the generator so that the bracket 12 of the main body 1 is directly opposite to the stator of the generator.

[0102] That is to say, after the connecting member 23 is connected to the stator, since the guide member 21 and the connecting member 23 are rotatably connected and the guide member 21 is inserted into the connecting hole 2321 of the bracket 12 in the main body 1, a lifting device such as a crane can be used to lift the main body 1 relative to the stator of the generator, so that the bracket 12 of the main body 1 is opposite to the stator of the generator, which facilitates the subsequent positioning of the bracket 12 and the stator of the generator.

[0103] S33, screw the locking member 22 to make the locking member 22 approach the connecting member 23 along the guide member 21 until the locking member 22 clamps the bracket 12 between the connecting member 23 and the locking member 22.

[0104] In the above steps, by screwing the locking piece 22, the locking piece 22 is moved along the guide piece 21 close to the connecting piece 23 under the action of the thread, and the bracket 12 is pushed to continuously approach the connecting piece 23. Finally, the locking piece 22 clamps the bracket 12 between the connecting piece 23 and the locking piece 22, thereby locking the bracket 12.

[0105] In some embodiments, the barring device further includes a first positioning mechanism and a second positioning mechanism, and the installation method further includes the following steps:

[0106] S4, a positioning step, using a first positioning mechanism to position the bracket 12 on the stator, and using a second positioning mechanism to position the rotating structure 11 on the rotor.

[0107] Exemplarily, the first positioning mechanism includes a first positioning pin 31 and a first positioning member 32 connected to each other, the second positioning mechanism includes a second positioning pin 41 , the bracket 12 is provided with a first positioning hole 123 , and the rotating structure 11 is provided with a second positioning hole 1111 .

[0108] like Figure 6 As shown, the specific steps of the above step S4 can be as follows:

[0109] S41, connecting the first positioning member 32 to the stator of the generator by using connecting bolts or other connecting members.

[0110] S42 , inserting the first positioning pin 31 into the first positioning hole 123 .

[0111] S43, inserting the second positioning pin 41 into the second positioning hole 1111, and making a portion of the second positioning pin 41 extend out of the second positioning hole 1111;

[0112] S44, plugging the second positioning pin 41 extending from the second positioning hole 1111 into the rotor of the generator.

[0113] In some embodiments, the first locating pin 31 and the second locating pin 41 may be conical pins, so that the first locating pin 31 can be quickly inserted into the first locating hole 123, and the second locating pin 41 can be quickly inserted into the rotor of the generator, so that the winch device can be more accurately positioned on the generator.

[0114] In some embodiments, the installation method further comprises the following steps:

[0115] S5, unlocking step, releasing the locking member 22 from locking the bracket 12.

[0116] That is, after the winching device is positioned on the generator, the locking member 22 is released from the bracket 12. The locking member 22 can be released by reversely twisting the locking member 22 to move the locking member 22 away from the connecting member 23 along the guide member 21, and releasing the locking member 22 from the bracket 12, so that the load of the winching device is borne by the first positioning mechanism and the second positioning mechanism.

[0117] In some embodiments, the installation method further comprises the following steps:

[0118] S6, a fixing step, fixing the bracket 12 to the stator, and fixing the rotating structure 11 to the rotor.

[0119] Through the above steps, the bracket 12 is fixedly connected to the stator by connecting bolts and other connecting components, thereby reducing the possibility of relative displacement between the bracket 12 and the stator along the axial direction of the generator. The rotating structure 11 is fixedly connected to the rotor by connecting bolts and other connecting components, thereby reducing the possibility of relative displacement between the rotating structure 11 and the rotor along the axial direction of the generator. The winch device is firmly connected to the end of the generator.

[0120] The embodiment of the present application also provides a wind turbine generator set, which includes a generator and a winch device provided by the above technical solution, wherein the rotating structure 11 of the winch device is connected to the rotor of the generator, and the bracket 12 of the winch device is connected to the stator of the generator. Since the winch device provided by the above technical solution has a low installation difficulty and a high installation speed, it is conducive to reducing the installation difficulty of the wind turbine generator set and improving the installation speed.
