[0039] As a kind of electric power equipment for converting wind energy into mechanical energy and then into electric energy, wind turbine can capture wind energy by blade, convert wind energy into mechanical energy, and then convert mechanical energy into electric energy by generator. With the increasing importance of environment, wind turbine is more and more concerned by people. Compared with land, the wind resources on sea are more abundant, and the advantages of offshore wind power project are more obvious, and the capacity of offshore wind turbine is more and more increased.

[0040] The shaft structure of the wind turbine generator mainly comprises a main shaft, a bearing seat, front bearing inner and outer rings and rear bearing inner and outer rings. With the continuous increase of the capacity of the wind turbine generator, the wind turbine generator is increasingly large, and the size and weight of the shaft structure thereon are increasingly large, and the assembly difficulty thereof is increasingly large.

[0041] In order to reduce the assembly difficulty of the shaft and the bearing seat in the wind turbine generator, the application provides an assembly device of a wind turbine generator for mounting a shaft to a bearing seat, which comprises a hoisting main body and a turning mechanism. The hoisting main body comprises a bearing beam and a lifting beam which are connected to each other and intersected.

The turning mechanism comprising a first driver and a rotating structure is arranged on the hoisting main body. The rotating structure is rotatably connected to the bearing beam and is used for connecting with the end surface of the shaft. The first driver is in transmission connection with the rotating structure to drive the rotating structure to drive the shaft to rotate relative to the bearing beam. In the above structure, since the hoisting main body is provided with the turning mechanism, the assembly device of the wind turbine generator can drive the shaft connected with the rotating structure of the turning mechanism to rotate in the process of mounting the shaft to the bearing seat, so that the shaft can be mounted to the bearing seat while rotating, thereby reducing the assembly difficulty of the shaft and the bearing seat and being beneficial to improving the assembly efficiency of the wind turbine generator.

[0042] The technical scheme of the assembly device of the wind turbine generator provided by the specific embodiment of the application will be further described below.

[0043] Some embodiments of the application provide an assembly device of a wind turbine generator as shown in Figure 1 , which is used for mounting a shaft 100 to a bearing seat 200, and with reference to Figure 2 , the assembly device of the wind turbine generator comprises a hoisting main body 1 and a turning mechanism 2. The hoisting main body 1 comprises a bearing beam 11 and a lifting beam 12 which are connected to each other and intersected. The lifting beam 12 is provided with a lifting structure 121 for connecting with a first lifting device. The hoisting main body 1 can overturn the shaft 100 under the action of the first lifting device so as to mount the shaft 100 into the bearing seat 200. The turning mechanism 2 is arranged on the hoisting main body 1. The turning mechanism 2 comprises a first driver 21 and a rotating structure 22. The rotating structure 22 is rotatably connected to the bearing beam 11. The rotating structure 22 is used for connecting with the end surface of the shaft 100. The first driver 21 is in transmission connection with the rotating structure 22 to drive the rotating structure 22 to drive the shaft 100 to rotate relative to the bearing beam 11.

[0044] The shaft 100 can be a main shaft in a wind turbine generator set, which serves as a torque transmission component to transmit the torque received by a wind wheel in the wind turbine generator set to a generator to drive the generator to rotate. At present, with the wind turbine generator set becoming larger and larger, the main shaft as a torque transmission component is also becoming larger and larger, and its installation to the bearing seat 200 is becoming more and more difficult.

[0045] The hoisting body 1 can refer to a component for connecting and supporting the shaft 100 during hoisting of the shaft 100, so as to facilitate overturning and installation of the shaft 100. The carrying beam 11 and the hoisting beam 12 are two beam structures connected with each other in the hoisting body 1, which serve as main components in the hoisting body 1 to transmit loads and provide installation platforms for other components in the assembly device of the wind turbine generator set.

[0046] The carrying beam 11 can be a beam structure in which the turning mechanism 2 is arranged, which can carry the load of the shaft 100 connected to the turning mechanism 2. The hoisting beam 12 can be a beam structure for connecting with the first hoisting device, and the first hoisting device can hoist the main shaft connected to the turning mechanism 2 by hoisting the hoisting beam 12.

[0047] The carrying beam 11 and the hoisting beam 12 are arranged perpendicularly, that is, the extension direction of the carrying beam 11 is perpendicular to the extension direction of the hoisting beam 12, so that the main shaft installed above the carrying beam 11 by the turning mechanism 2 can be parallel to the hoisting beam 12, and the first hoisting device can adjust the position of the main shaft by hoisting the hoisting beam 12. Figure 3 and Figure 4 The hoisting body 1 can change the shaft 100 from being arranged in the vertical direction to being arranged in the horizontal direction under the action of the first hoisting device, so as to overturn the main shaft and facilitate installation of the shaft 100 in the bearing seat 200 in the horizontal direction.

[0048] The turning mechanism 2 can be a mechanism for turning the shaft 100 during installation of the shaft 100 into the bearing seat 200. The rotating structure 22 can be a component for driving the shaft 100 to rotate, which is rotatably connected to the carrying beam 11 and used to connect with the end surface of the shaft 100, so that the rotating structure 22 can drive the shaft 100 to rotate when the rotating structure 22 rotates relative to the carrying beam 11.

[0049] Exemplarily, the rotating structure 22 can be a rotating support or a turntable bearing with external teeth, so that the end surface of the shaft 100 can drive the shaft 100 to rotate around its own axis when connected to the rotating structure 22.

[0050] The first driver 21 can be a device for driving the rotation of the slewing structure 22. The first driver 21 is mounted on the hoisting body 1, and its output end is drivingly connected to the slewing structure 22, so that the first driver 21 can drive the slewing structure 22 to rotate relative to the bearing beam 11.

[0051] In the above structure, since the turning gear mechanism 2 is arranged on the hoisting body 1, the assembly device of the wind turbine generator set can drive the shaft 100 connected to the slewing structure 22 of the turning gear mechanism 2 to rotate during the installation of the shaft 100 to the bearing seat 200, so that the shaft 100 can be installed to the bearing seat 200 while rotating, which reduces the assembly difficulty of the shaft 100 and the bearing seat 200, and is beneficial to improve the assembly efficiency of the wind turbine generator set.

[0052] In some embodiments, referring to Figure 5 , the assembly device of the wind turbine generator set further comprises a limiting mechanism 3, the limiting mechanism 3 comprises a support arm 31 and a connecting piece 32 arranged on the support arm 31, the connecting piece 32 can be connected to the hoisting beam 12, and the support arm 31 is used to be connected with the bearing seat 200.

[0053] The limiting mechanism 3 can be a mechanism for limiting the relative position of the hoisting body 1 and the bearing seat 200. The support arm 31 can be an arm-shaped member for supporting between the bearing seat 200 and the hoisting beam 12, one end of which is used to be connected with the bearing seat 200, and the other end of which is used to be connected with the hoisting beam 12.

[0054] The connecting piece 32 can be a component for connecting the support arm 31 and the hoisting beam 12. By connecting the support arm 31 to the bearing seat 200 and connecting the support arm 31 to the side wall of the hoisting beam 12 by the connecting piece 32, the possibility of the bearing seat 200 rotating with the shaft 100 during the turning process can be reduced.

[0055] Exemplarily, the limiting mechanism 3 comprises two opposite support arms 31, one end of the support arm 31 is connected to the bearing seat 200, and the other end is provided with a connecting piece 32. The connecting piece 32 can comprise a clamping wheel, the rolling direction of the clamping wheel is arranged in the horizontal direction, and the ends of the two support arms 31 away from the bearing seat 200 are clamped to the two opposite sides of the hoisting beam 12 through the clamping wheel to clamp and limit the hoisting beam 12 from both sides, so that the friction between the shaft piece 100 and the bearing seat 200 does not easily cause the position dislocation of the hoisting body 1 and the shaft piece 100 when the hoisting body 1 is turned over and inserted into the bearing seat 200 for turning; moreover, the clamping wheel can roll during the process of the shaft piece 100 being loaded into the bearing seat 200, so that the shaft piece 100 can smoothly extend into the bearing seat 200. The connecting piece 32 can also comprise a connecting bolt, and the ends of the two support arms 31 away from the bearing seat 200 are respectively abutted to the two opposite sides of the hoisting beam 12 through the connecting bolt to clamp and limit the hoisting beam 12 from both sides, so that the friction between the shaft piece 100 and the bearing seat 200 does not easily cause the position dislocation of the hoisting body 1 and the shaft piece 100 when the hoisting body 1 is turned over and inserted into the bearing seat 200 for turning.

[0056] In some embodiments, with continued reference to Figure 2 , the rotating structure 22 is provided with a positioning structure 221 for connecting with the end face of the shaft piece 100.

[0057] The positioning structure 221 can be a structure for guiding and positioning when the shaft piece 100 is installed on the rotating structure 22, which is used to make the central axis of the shaft piece 100 coincide with the central axis of the rotating structure 22. Exemplarily, the positioning structure 221 is provided with a plurality of positioning structures 221 arranged on the surface of the rotating structure 22 facing the shaft piece 100, and the shaft piece 100 is connected to the rotating structure 22 through the positioning structure 221.

[0058] The connection of the positioning structure 221 with the end face of the shaft piece 100 can be that the positioning structure 221 can comprise a positioning pin and a connecting bolt, the end of the shaft piece 100 is provided with a connecting hole and a positioning hole, the connecting hole is matched with the positioning pin, and the connecting bolt connects the shaft piece 100 to the rotating structure 22 through the connection with the connecting hole.

[0059] In some embodiments, the positioning structure 221 is connected to the rotating structure 22 through the connecting bolt, so that the positioning structure 221 is convenient to disassemble and replace, and the assembly device of the wind turbine generator can adapt to different models of shaft pieces 100 by replacing different models of positioning structures 221.

[0060] In some embodiments, the assembly device of the wind turbine generator set further comprises a turnover base 4, the turnover base 4 is provided with a rotating shaft 41, the carrying beam 11 is provided with a rotating sleeve 111, and the rotating shaft 41 is rotatably arranged in the inner cavity of the rotating sleeve 111.

[0061] The turnover base 4 can be a support for assisting in hoisting and overturning the main body 1. By arranging the rotating shaft 41 on the turnover base 4, arranging the rotating sleeve 111 on the carrying beam 11, and rotatably arranging the rotating shaft 41 in the inner cavity of the rotating sleeve 111, the main body 1 can rotate around the rotating shaft 41 when it is hoisted and overturned, which is beneficial to improve the convenience of hoisting and overturning the main body 1 by the first hoisting device.

[0062] Exemplarily, the turnover base 4 can be arranged on the ground, which can provide a larger supporting force when the main body 1 is hoisted and overturned, so that the main body 1 carrying the shaft component 100 can be smoothly hoisted and overturned.

[0063] In some embodiments, the wall of the rotating sleeve 111 is provided with a discharge port 1111 communicating with the inner cavity of the rotating sleeve 111, and the cross-sectional width of the discharge port 1111 is greater than the diameter of the rotating shaft 41.

[0064] The discharge port 1111 can be an opening for discharging the rotating shaft 41 from the inner cavity of the rotating sleeve 111. By setting the cross-sectional width of the discharge port 1111 to be greater than the diameter of the rotating shaft 41, the rotating shaft 41 can be discharged from the inner cavity of the rotating sleeve 111 along the discharge port 1111.

[0065] By arranging the discharge port 1111 communicating with the inner cavity of the rotating sleeve 111 on the wall of the rotating sleeve 111, the rotating shaft 41 in the inner cavity of the rotating sleeve 111 can be discharged from the discharge port 1111, so that the main body 1 can be hoisted to a suitable height by the first hoisting device, which is convenient for subsequent installation into the bearing seat 200.

[0066] In some embodiments, the hoisting structure 121 comprises at least two hoisting members arranged at intervals and used for connecting with the first hoisting device, and at least one hoisting member is adjustably connected to the hoisting beam 12.

[0067] The hoisting member can be a member arranged on the hoisting beam 12 for connecting with the first hoisting device, so that the first hoisting device can hoist the hoisting beam 12.

[0068] Exemplarily, the first hoisting device can be a travelling crane, and the hoisting member can be an ear, and the travelling crane can be connected to the ear through a lifting tool such as a sling or a hook to hoist the main body 1 for transporting the main body 1.

[0069] The at least one hoisting member is adjustably connected to the hoisting beam 12. The hoisting member can be adjustably connected to the hoisting beam 12, or two hoisting members can be adjustably connected to the hoisting beam 12.

[0070] By adjustably connecting the at least one hoisting member to the hoisting beam 12, the connection position of the first hoisting device to the hoisting beam 12 is adjustable, the spacing between the two hoisting members can be adjusted, the angle between the hoisting beam 12 and the horizontal plane can be adjusted by adjusting the spacing between the two hoisting members, and thus the angle between the central axis of the shaft 100 and the horizontal plane can be adjusted, facilitating the installation of the shaft 100 into the bearing seat 200.

[0071] In some embodiments, referring to Figure 6 The assembly device of the wind turbine generator further comprises an adjusting assembly 5, the adjusting assembly 5 comprises a sliding sleeve 51 and a second driver 52, the sliding sleeve 51 is slidably sleeved on the hoisting beam 12, the second driver 52 is connected to the hoisting body 1, the output end of the second driver 52 is drivingly connected to the sliding sleeve 51, and the position-adjustable hoisting member is fixed on the sliding sleeve 51.

[0072] The adjusting assembly 5 can be an assembly for adjusting the position of the hoisting member. The sliding sleeve 51 can be a member slidably sleeved on the outside of the hoisting beam 12, which can slide on the outside of the hoisting beam 12. By arranging the hoisting member on the sliding sleeve 51, the hoisting member is adjustably arranged on the hoisting beam 12.

[0073] The second driver 52 can be a driver for driving the sliding sleeve 51 to slide. By fixedly connecting the second driver 52 to the hoisting body 1 and drivingly connecting the output end of the second driver 52 to the sliding sleeve 51, the second driver 52 can drive the sliding sleeve 51 to slide along the extension direction of the hoisting beam 12.

[0074] Exemplarily, the second driver 52 can be a hydraulic cylinder, and the second driver 52 can also be a servo electric cylinder, so that the sliding sleeve 51 can slide along the extension direction of the hoisting beam 12 under the driving of the second driver 52, realizing the position adjustment of the hoisting member located on the sliding sleeve 51.

[0075] In some embodiments, the assembly device of the wind turbine generator further comprises an inclination sensor connected to the end surface of the shaft 100 away from the slewing structure 22, the inclination sensor being used for detecting the horizontal state of the shaft 100.

[0076] The inclination sensor can be a sensor for detecting the angle between the shaft 100 and the horizontal plane, which is helpful to keep the shaft 100 horizontal and improve the convenience of installing the shaft 100 into the bearing seat 200.

[0077] Due to the effect of gravity, the end of the shaft 100 far from the slewing structure 22 is more likely to tilt and sag. By connecting the tilt sensor to the end surface of the shaft 100 far from the slewing structure 22, the place where the shaft 100 is more likely to tilt and sag can be kept horizontal.

[0078] In some embodiments, the assembly device of the wind power generator set further comprises a controller, which is electrically connected with the tilt sensor and the second driver 52.

[0079] The controller can be used to control the second driver 52 to adjust the horizontal state of the shaft 100. By electrically connecting the controller with the tilt sensor and the second driver 52, the controller can control the action of the second driver 52 according to the horizontal state of the shaft 100 measured by the tilt sensor, so that the controller can realize more accurate adjustment of the horizontal state of the shaft 100.

[0080] In some embodiments, the controller can be a centralized or distributed controller. For example, the controller can be a single microcontroller or composed of multiple distributed microcontrollers. The microcontroller can run a control program to control the second driver 52 to realize its functions.

[0081] In some embodiments, the assembly device of the wind power generator set further comprises an auxiliary mechanism 6, which is connected to the end surface of the shaft 100 far from the slewing structure 22, and the auxiliary mechanism 6 is provided with a lifting appliance for connecting with the second lifting device.

[0082] The auxiliary mechanism 6 can be a mechanism for assisting the installation of the shaft 100 into the bearing 62. By connecting the auxiliary mechanism 6 to the end surface of the shaft 100 far from the slewing structure 22 and providing a lifting appliance on the auxiliary mechanism 6, the second lifting device can lift the end of the shaft 100 far from the slewing structure 22 through the lifting appliance on the auxiliary mechanism 6, which is conducive to reducing the degree of tilt and sag of the end of the shaft 100 far from the slewing structure 22 and helps to reduce the difficulty of installing the shaft 100 into the bearing seat 200.

[0083] The lifting appliance provided on the auxiliary mechanism 6 can be an ear or a ring, which can be set according to actual conditions by those skilled in the art.

[0084] In some embodiments, referring to Figure 7 , the auxiliary mechanism 6 comprises a turntable 61, a bearing 62 and a pulling member 63, the turntable 61 is rotatably connected to the pulling member 63 through the bearing 62, the turntable 61 is connected to the end surface of the shaft 100 far from the slewing structure 22, and the pulling member 63 is used to connect with the bearing seat 200.

[0085] The pulling member 63 can be a component in the auxiliary mechanism 6 that does not rotate with the turntable 61, which is used to receive the pulling force provided by an external device.

[0086] The bearing 62 can be a bearing 62 capable of providing an axial force. Exemplarily, the bearing 62 can be a thrust ball bearing 62 or a thrust roller bearing 62, so that the bearing 62 can transmit the force received by the pulling member 63 to the rotating disc 61 to drive the shaft member 100 to enter the bearing housing 200.

[0087] The rotating disc 61 can be a disc-shaped member rotating synchronously with the shaft member 100. The rotating disc 61 is rotatably connected to the pulling member 63 through the bearing 62, so that the rotating disc 61 can rotate synchronously with the shaft member 100 relative to the pulling member 63 during the process of pulling the shaft member 100 into the bearing housing 200, so that the shaft member 100 can be rotated and assembled into the bearing housing 200 under the pulling of the pulling member 63, which is beneficial to reduce the difficulty of assembling the shaft member 100 into the bearing housing 200.

[0088] In some embodiments, continuing to refer to Figure 1 The assembly device of the wind power generator set further comprises a drawbar mechanism 7 connected to the bearing housing 200 and connected with the pulling member 63.

[0089] The drawbar mechanism 7 can be a device for applying a pulling force to the pulling member 63, so that the shaft member 100 can enter the bearing housing 200 and extend away from the end of the slewing structure 22 to be assembled into the bearing housing 200. The drawbar mechanism 7 is connected to the side of the bearing housing 200 away from the slewing structure 22, so that the drawbar mechanism 7 can apply a sufficient pulling force to the shaft member 100 to pull the shaft member 100 through the bearing housing 200.

[0090] The drawbar mechanism 7 is fixed to the side of the bearing housing 200 away from the slewing structure 22, and the output end can pass through the inner cavity of the bearing housing 200 and be connected to the end of the shaft member 100 away from the slewing structure 22.

[0091] In some embodiments, the assembly device of the wind power generator set further comprises a bearing platform 8, and the bearing housing 200 is arranged on the bearing platform 8.

[0092] The bearing platform 8 can be a platform for bearing the bearing housing 200. By arranging the bearing housing 200 on the bearing platform 8, the bearing housing 200 can be stably fixed, which is beneficial to stably assemble the shaft member 100 into the bearing housing 200.
