Description

A wind turbine pitch motor installation tool Technical Field

[0001] The present invention relates to the technical field of motor mounting tooling, and in particular to a wind turbine variable pitch motor mounting tooling. Background Art

[0002] A variable-pitch wind turbine, also known as a wind turbine, is a device used for wind power generation. It consists of a rotor, main shaft, variable-pitch mechanism, and generator. The rotor, the core component of a wind turbine, typically consists of several blades whose angles can be adjusted according to the strength and direction of the wind. The variable-pitch mechanism controls the blade angle, allowing the rotor to automatically adjust according to wind speeds, thereby maximizing wind energy capture. The generator converts the rotor's rotational motion into electrical energy for use in the power grid or storage.

[0003] Installing a pitch motor typically requires two people: one person lifts the motor while the other uses lighting to verify alignment with the pitch gearbox. Only when the shaft key is aligned with the keyway can the motor be safely lowered. This process is a significant test of coordination and poses safety risks such as crushing and bruising, as well as low efficiency.

Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0030] Example 1

[0031] Referring to Figures 1 to 2, a schematic diagram of the overall structure of a wind turbine pitch motor installation tool is provided. As shown in Figure 1, a wind turbine pitch motor installation tool includes a base 100; the base 100 includes legs 101 and reinforcing beams 102 provided on the legs 101; there are two legs 101, and both legs 101 are provided with reinforcing beams 102 for increasing the strength of the legs 101. There is a space between the two legs 101. When the wind turbine pitch motor is installed on the pitch gearbox, the pitch gearbox is located in the space between the two legs 101.

[0032] The lifting mechanism 200 includes a lifting top plate 201 that is slidably connected to the base 100, and a lifting connection member 202 provided between the lifting top plate 201 and the base 100 for driving the lifting top plate 201; the lifting connection member 202 is a screw rod that is threadedly connected to the reinforcing beam 102, and its end is rotatably connected to the lifting top plate 201.

[0033] The end of the screw rod is rotatably connected to the lifting top plate 201 through a sleeve or a bearing. The forward and reverse rotation of the screw rod can drive the lifting top plate 201 to rise and fall. The lifting top plate 201 is slidably connected to the leg 101 through multiple anti-rotation columns 203.

[0034] The supporting mechanism includes a movable beam 301 provided on the lifting top plate 201 and capable of moving in a first direction, a supporting beam 302 detachably connected to the movable beam 301, and an adjustment platform 303 provided between the movable beam 301 and the supporting beam 302 and capable of moving in a second direction; in this embodiment, the adjustment platform 303 is used to support the wind turbine pitch motor. When aligning the wind turbine pitch motor and the pitch gearbox, the supporting beam 302 and the movable beam 301 can be moved in the first direction, and the adjustment platform 303 moves in the second direction. This time, the movement in the first direction is to be able to move back and forth in the first direction, and the movement in the second direction is to be able to move back and forth in the second direction, thereby adjusting the position of the wind turbine pitch motor so that the wind turbine pitch motor and the pitch gearbox are aligned.

[0035] The first direction is perpendicular to the second direction, so that the wind turbine pitch motor can be adjusted to a wider range of positions.

[0036] Specifically, the lifting top plate 201 is provided with a first track 201a; the moving beam 301 is provided with a first roller seat 301a, and the moving beam 301 is connected to the first track 201a through the first roller seat 301a; the supporting beam 302 is connected to the moving beam 301 through the first roller seat 301a.

[0037] The first roller seat 301a includes a main wheel seat body 301a-1 and a secondary wheel seat body 301a-2 which are movably arranged on the first track 201a, a synchronization column 301a-3 arranged between the main wheel seat body 301a-1 and the secondary wheel seat body 301a-2, and a connecting member 301a-4 arranged on the secondary wheel seat body 301a-2; the main wheel seat body 301a-1 is fixedly connected to the moving beam 301, and the secondary wheel seat body 301a-2 can be connected to the supporting beam 302 through the connecting member 301a-4.

[0038] Among them, the main wheel seat body 301a-1 and the secondary wheel seat body 301a-2 both have a first roller, and the first roller is arranged on the inner side of the first track 201a and can move along the first track 201a. The extension direction of the first track 201a is parallel to the first direction. The synchronization column 301a-3 can ensure that the main wheel seat body 301a-1 and the secondary wheel seat body 301a-2 move synchronously. At the same time, mounting holes are opened on the connecting member 301a-4 and the supporting beam 302. The connecting member 301a-4 and the supporting beam 302 can be connected by bolts. Through the above scheme, the supporting beam 302 and the movable beam 301 can be guaranteed to move synchronously.

[0039] Furthermore, the adjustment platform 303 includes a movable platform body 303a disposed on the supporting beam 302 / moving beam 301 and capable of moving along the second direction, and a second roller seat 303b disposed on the movable platform body 303a.

[0040] A second track (303c) is provided on both the supporting beam 302 and the movable beam 301. The movable platform 303a is fixedly connected to the second roller seat 303b. The second roller of the second roller seat 303b is rolled on the inner side of the second track (303c). The extension direction of the second track (303c) is parallel to the second direction. In this embodiment, there are two second roller seats 303b and two movable platforms 303a. The two second roller seats 303b are distributed on the second track (303c) of the supporting beam 302 and the movable beam 301.

[0041] Of course, the two second roller seats 303b can be connected by a detachable structure such as a long bolt, so that the two second roller seats 303b can maintain synchronous movement.

[0042] Operation process: When installing the wind turbine pitch motor onto the pitch gearbox, the pitch gearbox is located in the space between the two legs 101, and the adjustment platform 303 is used to support the wind turbine pitch motor. When aligning the wind turbine pitch motor and the pitch gearbox, the support beam 302 and the movable beam 301 can be moved along the first direction, and the adjustment platform 303 moves along the second direction. This time, the movement along the first direction is to be able to move back and forth along the first direction, and the movement along the second direction is to be able to move back and forth along the second direction, thereby adjusting the position of the wind turbine pitch motor so that the wind turbine pitch motor and the pitch gearbox are aligned.

[0043] After the position is aligned, by rotating the screw in the opposite direction, the lifting top plate 201 and the support mechanism move downward, the adjustment platform 303 moves downward, and the wind turbine pitch motor moves toward the pitch gearbox below until the shaft key of the wind turbine pitch motor enters the keyway inside the pitch gearbox flange.

[0044] After the wind turbine pitch motor and pitch gearbox are connected by connecting bolts, the support beam 302 is removed from the secondary wheel seat body 301a-2. At this time, there is no obstruction on one side of the tooling, and the tooling can be evacuated from the outside of the pitch gearbox.

[0045] Example 2

[0046] 3 , this embodiment differs from the first embodiment in that: in order to keep the wind turbine pitch motor stable when the wind turbine pitch motor and the pitch gear set are connected by bolts, the wind turbine pitch motor installation tool further includes a positioning mechanism 400; the positioning mechanism 400 is used to fix the wind turbine pitch motor being connected to the pitch gear set, and the positioning mechanism 400 includes a placement seat 401, which is provided on the supporting beam 302 / moving beam 301, and is located between the supporting beam 302 and the moving beam 301. 01 are both connected to a mounting seat 401; a clamping member 402 is slidably arranged on the mounting seat 401, and both mounting seats 401 are provided with a clamping member 402, and the two clamping members 402 can be close to each other to clamp the wind turbine pitch motor between the two; an adjusting screw rod 403 is threadedly connected to the mounting seat 401, and can drive the clamping member 402 to move, and an adjusting screw rod 403 is provided on both mounting seats 401, and the position of the two clamping members 402 is adjusted by adjusting the screw rod 403.

[0047] The clamping member 402 can be straight or arc-shaped to adapt to wind turbine pitch motors of different shapes. The clamping member 402 has two limit rods 404, which are slidingly connected to the mounting seat 401 to avoid the problem of rotation of the clamping member 402.

[0048] The rest of the structure is the same as that of Example 1.

[0049] Operation process: When the wind turbine pitch motor and the pitch gear set are connected, by rotating the two adjustment screws 403, the two clamping parts 402 can be driven so that the two clamping parts 402 approach each other, contacting the wind turbine pitch motor from both sides, so that the wind turbine pitch motor remains stable during the connection.

[0050] Example 3

[0051] 3 and 4 , this embodiment differs from the above embodiments in that: in order to adjust the position of the positioning mechanism 400 so that the position of the positioning mechanism 400 corresponds to the position of the wind turbine pitch motor, the pitch motor mounting tool further includes a mounting mechanism 500 connecting the mounting seat 401 and the support beam 302 / moving beam 301; the mounting mechanism 500 includes a mounting rod 501 mounted on the support beam 302 / moving beam 301; and a mounting member 502 provided on the mounting rod 501 and capable of moving along the mounting rod 501.

[0052] An installation mechanism 500 is provided on both the supporting beam 302 and the movable beam 301. A socket groove M is opened on both the supporting beam 302 and the movable beam 301. The placement rod 501 is installed on the inner side of the socket groove M. The installation component 502 can slide along the placement rod 501, and the sliding direction is the second direction, so that the operator can adjust the position of the installation component 502 through the position of the wind turbine pitch motor, thereby adjusting the position of the positioning mechanism 400, so that the positioning mechanism 400 can be aligned with the wind turbine pitch motor installation tooling.

[0053] Specifically, the placement rod 501 is provided with a guide groove 501a parallel to the extension direction of the placement rod 501; the mounting component 502 is provided with a through groove 502a, and the mounting component 502 is fixed with a guide block 502b at the end of the through groove 502a; the mounting component 502 is sleeved on the outer side of the placement rod 501 through the through groove 502a, and the guide block 502b is slidably connected to the inner side of the guide groove 501a.

[0054] The function of the guide groove 501a is to enable the guide block 502b to move inside the guide groove 501a when the mounting member 502 moves, thereby preventing the mounting member 502 from rotating. The extending direction of the placement rod 501 is parallel to the second direction.

[0055] The rest of the structure is the same as that of Example 2.

[0056] Operation process: When the position adjustment of the wind turbine pitch motor is completed, it is aligned with the pitch gearbox. At this time, the position of the mounting component 502 can be adjusted so that the mounting component 502 drives the mounting seat 401 to move, thereby achieving the movement of the clamping member 402. The positions of the two clamping members 402 are adjusted so that the two clamping members 402 can correspond to the wind turbine pitch motor, thereby making it more convenient to clamp and fix the wind turbine pitch motor.

[0057] Example 4

[0058] 5 to 6 , this embodiment is different from the above embodiments in that: in order to avoid operator errors, the tooling is removed before the connection between the wind turbine pitch motor and the pitch gearbox is completed, and the pitch motor installation tooling also includes a warning mechanism 600, which includes a sleeve group 601 provided between the support beam 302 and the movable beam 301, a force-bearing member 602 fixed to both ends of the sleeve group 601, an elastic member 603 in conflict with the force-bearing member 602, and an elastic member 603 provided on the force-bearing member 602. The warning column 604 on the component 602; the pushing mechanism, which includes a roller 701 provided at the end of the placement rod 501, a pushing arm 702 and a resistance arm 703 provided on the outside of the roller 701; the roller 701 provided at the support beam 302 and the roller 701 provided at the movable beam 301, and the pushing arms 702 and the resistance arms 703 provided on the two are in a mirror-symmetrical relationship; the warning column 604 is naturally located on the inner side of the support beam 302 / moving beam 301, and when the roller 701 provided at the support beam 302 and the roller 701 provided at the movable beam 301 rotate in the same direction, the warning column 604 can be extended. When the operator finds that the warning column 604 is extended, it can be understood that the wind turbine pitch motor and pitch gearbox are not fully connected.

[0059] In this embodiment, the supporting beam 302 and the movable beam 301 are provided with trigger chambers N at both ends of the sleeve groove M. The two ends of the placement rod 501 are cylindrical, and the cross-section of the middle part is rectangular. The two ends of the placement rod 501 and the supporting beam 302 or the movable beam 301 are in a rotational connection relationship, and the two ends of the placement rod 501 extend to the inner side of the trigger chamber N at both ends of the sleeve groove M respectively.

[0060] Specifically, the sleeve assembly 601 includes an external pipe member 601a slidably disposed on the movable beam 301 and an internal column member 601b slidably disposed on the supporting beam 302;

[0061] When the supporting beam 302 and the secondary wheel seat body 301a-2 are connected, the external tube component 601a is sleeved on the outside of the internal column component 601b, and the external tube component 601a and the internal column component 601b are abutted against each other. The ends of the external tube component 601a and the internal column component 601b that are away from each other are fixed with sliding columns 601c. The two sliding columns 601c are respectively slidably connected to the supporting beam 302 and the movable beam 301. The end of the sliding column 601c away from the sleeve group 601 extends to the inner side of the trigger chamber N, and the force-bearing component 602 is fixed to the sliding column 601c at one end of the trigger chamber N.

[0062] The warning column 604 is fixed to one end of the force-bearing component 602 away from the sliding column 601c, and an exposure hole N1 corresponding to the warning column 604 is opened on the side wall of the trigger chamber N. The elastic member is a spring, which is sleeved on the outside of the warning column 604 and is against the force-bearing component 602. In the natural state, the elastic members at both ends reach a balanced state, and the warning columns 604 at both ends will not be exposed from the exposure.

[0063] In this embodiment, the through slot 502a on the mounting member 502 is a rectangular slot, the width of which is adapted to the width of the placement rod 501. Synchronization holes 403a are provided at both ends of the two clamping members 402. Through the existing technology of long studs (not shown in the figure) and nuts, the two ends of the two clamping members 402 can be connected one-to-one, so that the wind turbine pitch motor is located between the two clamping members 402 and the two long studs.

[0064] When the wind turbine pitch motor and pitch gearbox are connected and the lifting top plate 201 continues to descend, the adjustment platform 303 no longer supports the wind turbine pitch motor. However, at this time, the two clamping members 402 are clamped on the outside of the wind turbine pitch motor, and the placement rod 501 descends along the through slot 502a.

[0065] The force-bearing member 602 defines a pushing groove 602 a at a position corresponding to the pushing arm 702 , and the force-bearing member 602 defines a resisting portion 602 b at a position corresponding to the resisting arm 703 .

[0066] In this embodiment, the force-bearing component 602 is U-shaped, and the thrust groove 602a is located at the bottom of the force-bearing component 602. In the natural state, the pushing arm 702 passes through the thrust groove 602a and penetrates the force-bearing component 602, and contacts the end of the thrust groove 602a. In the natural state, the contact arm 703 and the contact part 602b are in a separated state, so that the force-bearing component 602 can be pushed slightly.

[0067] When the wind turbine pitch motor and the pitch gearbox are connected and the lifting top plate 201 continues to descend, the adjustment platform 303 no longer supports the wind turbine pitch motor. If the wind turbine pitch motor and the pitch gearbox are not connected at this time, or the connection is not complete, the wind turbine pitch motor is not sufficiently fixed and there will be a problem of tipping over. When it tips over in the direction of one of the clamping members 402, the corresponding clamping member 402 will drive its corresponding mounting component 502 to swing under its thrust. At the same time, because the two clamping members 402 are in a connected state, when one of the clamping members 402 moves away from the wind turbine pitch motor under the thrust of the tipping of the wind turbine pitch motor, the other clamping member 402 will also move in the same direction, so that the two mounting components 502 swing synchronously.

[0068] The synchronous swinging of the two mounting components 502 will drive the two placement rods 501 to rotate in the same direction, thereby driving the two rollers 701 to rotate synchronously. At this time, the pushing arm 702 on one of the rollers 701, referred to as the A roller 701, will push its corresponding force-bearing component 602, referred to as the A force-bearing component 602, toward the other roller 701. Under the transmission of the sleeve group 601, the other force-bearing component 602, referred to as the B force-bearing component 602, also moves closer to its corresponding roller 701, referred to as the B roller 701. At this time, the B roller 701 also rotates synchronously with the A roller 701, so that the resistance arm 703 on the B roller 701 resists the resistance part 602b of the B force-bearing component 602, so that the B force-bearing component 602 cannot be pushed further. At this time, the A roller 701 cannot disengage from the inner side of the push groove 602a due to its small rotation angle, so it cannot rotate and is locked, thereby preventing the wind turbine pitch motor from continuing to tilt.

[0069] Therefore, in addition to connecting the two clamping members 402 through a long stud, the two clamping members 402 can also be connected through a connecting rod with rotatable ends.

[0070] At the same time, due to the slight displacement of the load-bearing component B 602 , the warning column 604 installed thereon extends out from the exposure hole N1 , reminding the operator that the wind turbine pitch motor is experiencing a tilt problem.

[0071] Through the above structure, before completely removing the tooling, the warning mechanism 600 can be used to conduct a preliminary test on whether the wind turbine pitch motor is stable. The wind turbine pitch motor can be tilted slightly under the action of the clamping member 402. After the slight tilt, it will be supported by the clamping member 402, and the thrust caused by the slight tilt can be displayed through the warning column 604, reminding the operator of the main problem of unstable installation.

[0072] The rest of the structure is the same as that of Example 3.

[0073] It is important to note that the construction and arrangement of the present application shown in a number of different exemplary embodiments are merely illustrative.
