Description

Technical Field

[0001] This utility model relates to the technical field of stator core processing equipment, and more specifically, it relates to an oil spraying device for the stator core of a wind power generation speed increaser box. Background Technology

[0002] The wind turbine gearbox is a core transmission component of a wind turbine generator set. Its main function is to increase the low speed of the wind turbine rotor to the high speed required by the generator, thereby achieving efficient power generation. The stator core, as a crucial component within the gearbox, requires oil spraying during manufacturing to prevent rusting during storage and use.

[0003] The patent with publication number CN222827117U discloses an automatic oil injection device for pressing and heating the stator and rotor iron core of new energy vehicles. By installing a slide rail inside the oil injection hood, the base is guided, and the second lifting cylinder pushes the base to slide up and down along the slide rail, thereby driving the oil nozzles on the top mounting plate and side mounting plate to move up and down, increasing the coverage of oil injection and making oil injection more comprehensive. At the same time, the collection pipe moves up and down with the oil nozzle, resulting in good collection effect and preventing leakage.

[0004] While the aforementioned device can move the oil injector up and down via a lifting cylinder, thereby increasing the coverage area of ​​the oil spray, both the inner and outer walls of the stator core require thorough oil spraying for rust prevention. The device can only spray oil on the outer surface of the stator core, making it difficult to ensure sufficient and uniform oil spraying across the entire stator core. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wind power generation speed-increasing box stator core oil spraying device that simultaneously sprays oil onto the inner and outer walls of the stator core, and ensures sufficient and uniform oil spraying through rotation and lifting during the oil spraying process.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The installation mechanism includes a workbench, a structural frame installed on the workbench, and a top plate installed on the top of the structural frame. The four outer spraying mechanisms are installed at the four corners of the workbench and are symmetrically arranged about the center of the workbench.

[0011] The present invention is further configured such that: the first sleeve penetrates the top plate, the second spray head is disposed at the bottom of the second spray pipe, and the second spray head is configured as an L-shaped bend.

[0012] The present invention is further configured such that: the rotating component includes a drive motor mounted on the lifting component, the output end of the drive motor is connected to a driving wheel, a driven wheel is connected to one side of the driving wheel, and the first sleeve passes through the driven wheel.

[0013] The present invention is further configured such that: the lifting assembly includes a lifting frame installed on the top plate, the lifting frame is provided with a lifting guide rail, the side wall of the lifting guide rail is provided with a sliding plate, a connecting plate is installed on the sliding plate, and the first sleeve passes through the connecting plate.

[0014] The present invention is further configured such that: the support platform mechanism includes a turntable rotatably mounted at the center of the worktable, and a limit ring is provided on the top of the turntable.

[0015] The beneficial effects of this utility model are:

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Please refer to Figure 1-2 A wind power generation speed increaser box stator core oil spraying device includes an installation mechanism 1, an outer spraying mechanism 2, an inner spraying mechanism 3 installed inside the installation mechanism 1, and a support platform mechanism 4. When the stator core needs to be sprayed with oil for rust prevention, the stator core can be placed on the support platform mechanism 4. The inner spraying mechanism 3 lifts and rotates to spray oil on the inner wall of the stator core, while the outer spraying mechanism 2 lifts and rotates from the four corners of the installation mechanism 1 to spray oil on the outer wall of the stator core.

[0030] Please refer to Figure 1-2 The installation mechanism 1 includes a workbench 11, a structural frame 14 mounted on the workbench 11, and a top plate 15 mounted on top of the structural frame 14. The workbench 11 is horizontally positioned, with a hollow installation box 12 at its bottom. A support frame 13, a rectangular frame structure, is connected to the bottom edge of the workbench 11 to support it. The structural frame 14, also a rectangular frame structure, is connected to the top edge of the workbench 11. Side plates 16 are connected to both sides of the structural frame 14 along the length of the workbench 11, and a protective curtain 17 is installed on each side of the structural frame 14 along the width of the workbench 11. Opening the protective curtains 17 allows the stator core to be placed onto the support platform mechanism 4 inside the installation mechanism 1. During oil spraying, the protective curtains 17 protect the installation mechanism 1 from splashing rust-preventive oil.

[0031] Please refer to Figure 2-3 and Figure 6The four external spraying mechanisms 2 are installed at the four corners of the workbench 11, symmetrically arranged about the center of the workbench 11. Each external spraying mechanism 2 includes a bracket 21, a limiting plate 24 slidably connected to the bracket 21, a first spray pipe 26 mounted on the limiting plate 24, and a first spray head 27 communicating with the first spray pipe 26. The bracket 21 is installed on the top of the workbench 11 and is perpendicular to the workbench 11. A vertical slide rail 22 is provided on the bracket 21, located on the side wall of the bracket 21 near the center of the workbench 11. A slider 23 is slidably mounted on the vertical slide rail 22. A driving component is provided inside the vertical slide rail 22 and the slider 23, enabling the slider 23 to move relative to the vertical slide rail 22. The driving component can be a lead screw, a micro linear motor, etc., and the type and structure of the driving component are well-known to those skilled in the art; this application does not specifically limit the type of driving component. The limiting plate 24 is L-shaped, and the slider 23 is connected to the limiting plate 24. A limiting hole 25 is provided on the limiting plate 24, and the limiting hole 25 is set at an angle. The first spray pipe 26 is installed inside the limiting hole 25, and the first spray head 27 is set at the bottom of the first spray pipe 26. The four first spray heads 27 are respectively set at an angle along the diagonal of the worktable 11, and the angle of the limiting hole 25 is consistent with the angle of the first spray head 27, so as to ensure that the four first spray heads 27 can spray oil on the outer wall surface of the stator core from different positions along the diagonal of the worktable 11, thereby improving the uniformity of the oil spraying anti-rust treatment. The first spray pipe 26 can be connected to an oil storage device. The anti-rust oil stored in the oil storage device can be transported to the first spray head 27 through the first spray pipe 26. After being sprayed out by the first spray head 27, it can make uniform contact with the outer wall of the stator core, thereby completing the oil spraying anti-rust treatment on the outer wall surface of the stator core. During the oil spraying and rust prevention process, the sliding block 23 can move along the vertical slide rail 22, which can simultaneously drive the first spraying pipe 26 to move, thereby moving the first spraying head 27 in the vertical direction and ensuring that the stator core outer wall is sprayed evenly in the vertical direction.

[0032] Please refer to Figure 1-2 and Figure 4-5The internal spraying mechanism 3 includes a lifting assembly 32 mounted on the top plate 15, a rotating assembly 31 and an internal spraying assembly 33 that pass through the top plate 15. The rotating assembly 31 can drive the internal spraying assembly 33 to rotate, ensuring uniform spraying in the circumferential direction of the stator core inner wall. The lifting assembly 32 can drive the internal spraying assembly 33 to move in the vertical direction, ensuring uniform spraying in the vertical direction of the stator core inner wall. The internal spraying assembly 33 includes a first sleeve 331 connected to the rotating assembly 31 and the lifting assembly 32 respectively, a second spraying pipe 332 disposed inside the first sleeve 331, and a second spraying head 333 communicating with the second spraying pipe 332. The first sleeve 331 passes through the top plate 15, and the second spraying pipe 332 passes through the first sleeve 331 and can rotate synchronously with the first sleeve 331. The second spraying head 333 is disposed at the bottom of the second spraying pipe 332 and is configured as an L-shaped bend. The second spray pipe 332 can be connected to an oil storage device. The rust-preventive oil stored in the oil storage device can be transported to the second spray head 333 through the second spray pipe 332. After being sprayed out through the second spray head 333, it can make uniform contact with the inner wall of the stator core, thus completing the oil spraying and rust prevention treatment of the inner wall surface of the stator core.

[0033] Please refer to Figure 1-2 and Figure 4-5 The rotating assembly 31 includes a drive motor 311 mounted on the lifting assembly 32. The output end of the drive motor 311 is connected to a drive wheel 312, which is located at the bottom of the top plate 15. A belt 313 is fitted onto the drive wheel 312, and a driven wheel 314 is connected to one side of the drive wheel 312. The belt 313 is fitted onto both the drive wheel 312 and the driven wheel 314. A first sleeve 331 passes through the driven wheel 314. The drive motor 311 can drive the drive wheel 312 to rotate, and through the transmission of the belt 313, it can synchronously drive the driven wheel 314 to rotate. During the rotation of the driven wheel 314, it can synchronously drive the first sleeve 331 to rotate.

[0034] Please refer to Figure 1-2 and Figure 4-5The lifting assembly 32 includes a lifting frame 321 mounted on the top plate 15, which is perpendicular to the top plate 15. A lifting guide rail 322 is provided on the lifting frame 321, a sliding plate 325 is provided on the side wall of the lifting guide rail 322, a connecting plate 326 is mounted on the sliding plate 325, and a fixing plate is mounted on the other side of the sliding plate 325. A drive motor 311 is mounted on the fixing plate. The lifting guide rail 322 is a linear guide rail, capable of driving the connecting plate 326 to move vertically. The type and structure of the linear guide rail are well-known to those skilled in the art, and this application does not specifically limit them. A first sleeve 331 penetrates the connecting plate 326, and a bearing 327 is provided inside the connecting plate 326. The first sleeve 331 is installed inside the bearing 327, ensuring that the first sleeve 331 can rotate relative to the connecting plate 326. The lifting frame 321 has vertically oriented lifting rails 323 at both ends, and lifting sliders 324 are connected to both ends of the sliding plate 325. The lifting sliders 324 can slide along the lifting rails 323. During the oil spraying and rust prevention process, the lifting rails 322 drive the sliding plate 325 to move vertically. As the connecting plate 326 moves with the sliding plate 325, the lifting sliders 324 slide synchronously along the lifting rails 323, thereby driving the first sleeve 331 set inside the connecting plate 326 to move synchronously vertically.

[0035] Please refer to Figure 2-3 The support platform mechanism 4 includes a turntable 41 rotatably mounted at the center of the worktable 11, with a limit ring 42 on the top of the turntable 41. A drive motor (not shown in the figure) is installed inside the mounting box 12, and its output is connected to the turntable 41, enabling the motor to rotate the turntable 41. The inner diameter of the limit ring 42 is adapted to the outer diameter of the stator core, limiting the stator core when it is placed on the turntable 41. After the oil spraying and rust prevention treatment is completed, the stator core can be flipped over, and the portion within the limit ring 42 that was not sprayed with oil can be re-sprayed for rust prevention to ensure sufficient oil spraying.

[0036] Specifically, when the stator core needs to be sprayed with oil for rust prevention, the stator core can be placed inside the limiting ring 42 on the turntable 41.

[0037] When applying oil spraying for rust prevention to the outer surface of the stator core, the rust-preventive oil is sprayed out through the first spray head 27. Four first spray heads 27 spray oil onto the outer surface of the stator core from different positions along the diagonal of the worktable 11, improving the uniformity of the rust prevention treatment. During the rust prevention process, the first spray heads 27 can be moved vertically by sliding the slider 23 along the vertical slide rail 22, ensuring uniform spraying of the stator core outer surface along the vertical direction.

[0038] When applying oil spraying for rust prevention to the inner wall surface of the stator core, the rust-preventive oil is sprayed out through the second spray head 333. Simultaneously, the drive motor 311 drives the drive wheel 312 to rotate, which in turn drives the driven wheel 314 and the first sleeve 331 to rotate, causing the second spray head 333 to rotate and ensuring uniform spraying along the circumferential direction on the outer wall of the stator core. The lifting guide rail 322 drives the connecting plate 326 to move vertically, which in turn drives the first sleeve 331 and the second spray head 333 to move, ensuring uniform spraying along the vertical direction on the outer wall of the stator core.

[0039] During the oil spraying process, the stator core rotates synchronously with the turntable 41 to ensure that the stator core can be sprayed evenly in all circumferential directions.

[0040] By sliding the limiting plate 24 relative to the bracket 21, the first spray head 27 is moved vertically, so that the four first spray heads 27 spray oil onto the outer wall surface of the stator core from different positions diagonally on the worktable 11, ensuring uniform spraying of the stator core outer wall; by rotating the component 31, the first sleeve 331 is rotated, and by lifting the component 32, the first sleeve 331 is moved vertically, so that the second spray head 333 can spray oil evenly onto the stator core outer wall in both the vertical and circumferential directions.
