[0002] In an electric field, the medium-speed gears of GE wind turbine gearboxes are prone to tooth breakage due to the large torque they transmit and the complex working environment.

[0003] Existing broken tooth repair devices suffer from insufficient positioning accuracy and inconvenient repair methods, making it difficult to meet the high-efficiency and precise repair requirements for medium-speed broken teeth. Therefore, there is an urgent need for a novel repair device that is simple in structure, practical, and convenient. Utility Model Content

[0004] The purpose of this application is to provide a device for repairing broken teeth in the medium-speed stage of a GE wind turbine gearbox with electric field, which has the advantages of simple and practical structure and solves the problems of low positioning accuracy and poor adaptability in the prior art.

[0005] The technical solution of the electric field GE wind turbine gearbox medium speed stage broken tooth repair device provided in this application is as follows: The electric field GE wind turbine gearbox medium speed stage broken tooth repair device includes a base frame, a support assembly, a repair assembly and a main controller. The support assembly includes a turntable rotatably sleeved inside the base frame. A support plate is fixedly connected to the upper surface of the turntable. A dual-axis motor is fixedly connected to the inner top wall of the turntable. A lead screw is fixedly connected to each of the two output shaft ends of the dual-axis motor. A moving plate is threadedly connected to the outer surface of each lead screw. A connecting plate is fixedly connected to the side of the two moving plates that are far apart from each other. A clamping plate is fixedly connected to the side of the two connecting plates that are close to each other.

[0006] A worm gear is fixedly connected to the rotating shaft end of the turntable, and a worm and a servo motor are mounted on the bottom surface of the base frame. The worm gear meshes with the worm, and the output shaft end of the servo motor is fixedly connected to the rotating shaft end of the worm.

[0007] By adopting the above technical solution, and with the help of the meshing transmission of worm gear and worm shaft, combined with the drive of servo motor, the turntable can be precisely rotated and adjusted, thereby driving the gearbox on the support plate to adjust its angle. This solves the problem of insufficient positioning accuracy of existing devices, and can also be stably limited after the position is adjusted to avoid shaking, thus improving the repair accuracy of broken teeth in the medium speed stage. At the same time, the dual-axis motor drives the lead screw to rotate, causing the moving plate to move the connecting plate and clamping plate, realizing stable clamping of gearboxes of different sizes and improving the adaptability of the device.

[0008] Preferably, the outer surfaces of both lead screws are rotatably sleeved in the inner wall of the turntable, and the bottom surface of the support plate is fixedly connected to two miniature brackets, with the ends of the two lead screws that are far apart from each other rotatably sleeved in the inner walls of the two miniature brackets respectively.

[0009] By adopting the above technical solution, the turntable and the miniature bracket provide dual support for the lead screw, enhancing the stability of the lead screw during rotation, preventing it from shaking due to force and affecting the moving accuracy of the moving plate, ensuring the clamping and positioning effect of the clamping plate on the gearbox, and making the repair work more convenient.

[0014] Preferably, the repair assembly includes two cylinders fixedly connected to the upper surface of the base frame, each cylinder having a horizontal plate fixedly connected to its output end, and each horizontal plate having a mechanical repair arm mounted on its upper surface.

[0015] By adopting the above technical solution, the cylinder can drive the horizontal plate to move up and down, thereby driving the mechanical repair arm to adjust its height, so that it can adapt to the repair needs of broken teeth in different positions inside the gearbox. The operation is flexible and convenient, solving the problem of inconvenient repair of existing devices and improving repair efficiency.

[0016] Preferably, the output ends of the two mechanical repair arms are respectively equipped with laser welding heads and mechanical grippers, and the upper surface of the base frame is equipped with an independent power supply electrically connected to the laser welding heads.

[0017] By adopting the above technical solutions, the mechanical gripper can stably hold the broken tooth fragments, ensuring precise docking between the fragments and the gear body. The laser welding head can quickly and efficiently complete the welding repair work. The independent power supply provides stable power support for the laser welding head, ensuring that the welding process is not affected by external power fluctuations, thus improving the repair quality and stability.

[0018] Preferably, two columns are fixedly connected to both sides of the upper surface of the base frame, and a fixing plate is fixedly connected to the top of each column. The two ends of the two horizontal plates are respectively slidably sleeved on the outer surface of the four columns.

[0019] By adopting the above technical solution, the column and fixing plate guide and limit the up and down movement of the horizontal plate, preventing the horizontal plate from tilting or shaking during movement, ensuring the stability of the mechanical repair arm, and enabling the laser welding head and mechanical gripper to accurately act on the broken tooth position, further improving the accuracy of the repair.

[0020] Preferably, the main controller is fixedly connected to the bottom surface of the base frame, and the electrical components inside the support assembly and the repair assembly are all electrically connected to the main controller.

[0021] By adopting the above technical solution, the main controller can centrally control the electrical components in the support and repair components to work together, realizing the automated linkage of operations such as gearbox clamping and positioning, angle adjustment, and clamping and welding of broken teeth. This simplifies the operation process, makes the repair work more convenient and efficient, and solves the problem of complex operation of existing devices.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A device for repairing broken teeth in the medium-speed stage of a GE wind turbine gearbox, referring to... Figure 1 , Figure 3 and Figure 5The system includes a base frame 1, a support assembly 2, a repair assembly 3, and a main controller 4. The support assembly 2 includes a turntable 201 rotatably fitted inside the base frame 1. A support plate 205 is fixedly connected to the upper surface of the turntable 201. A dual-axis motor 206 is fixedly connected to the inner top wall of the turntable 201. A lead screw 207 is fixedly connected to each of the two output shaft ends of the dual-axis motor 206. A moving plate 208 is threadedly connected to the outer surface of each lead screw 207. A connecting plate 210 is fixedly connected to the side of the two moving plates 208 that are far apart from each other. A connecting plate 210 is fixedly connected to the side of the two connecting plates 210 that are close to each other. The device includes a clamping plate 211, and the outer surfaces of two lead screws 207 are rotatably fitted into the inner wall of the turntable 201. The bottom surface of the support plate 205 is fixedly connected to two miniature brackets 209. The ends of the two lead screws 207 that are far apart from each other are rotatably fitted into the inner walls of the two miniature brackets 209. The turntable 201 and the miniature brackets 209 provide dual support for the lead screws 207, enhancing the stability of the lead screws 207 during rotation and preventing them from shaking due to force, which would affect the movement accuracy of the moving plate 208. This ensures the clamping and positioning effect of the clamping plate 211 on the gearbox, making the repair work more convenient.

[0033] Reference Figure 3 , Figure 4 and Figure 5 Two symmetrical guide posts 212 are installed on the bottom surface of the support plate 205. The two ends of the two movable plates 208 are slidably sleeved on the outer surfaces of the two guide posts 212. A limit block 213 is fixedly connected to the outer surface of each guide post 212. The guide posts 212 guide the movement of the movable plates 208, preventing the movable plates 208 from shifting as the lead screw 207 rotates, ensuring that the clamping plate 211 can accurately clamp the gearbox. The limit block 213 can limit the movement range of the movable plates 208, preventing them from moving excessively and detaching from the lead screw 207, thus improving the safety of the device. To ensure safety and reliability, the turntable 201 has evenly distributed heat dissipation vents 214 inside. These vents can dissipate the heat generated by the dual-axis motor 206 inside the turntable 201 during operation, preventing the components from being affected by excessive temperature and ensuring that the device can continuously and stably perform repair operations. A worm gear 202 is fixedly connected to the rotating shaft end of the turntable 201. A worm 203 and a servo motor 204 are mounted on the bottom surface of the base frame 1. The worm gear 202 meshes with the worm 203, and the output shaft end of the servo motor 204 is fixedly connected to the rotating shaft end of the worm 203.

[0034] Example 2: A device for repairing broken teeth in the medium-speed stage of a GE wind turbine gearbox, referring to... Figure 1 , Figure 2 and Figure 3Based on the same concept as Embodiment 1 above, this embodiment proposes a repair component 3 including two cylinders 301 fixedly connected to the upper surface of the base frame 1. Each cylinder 301 has a horizontal plate 302 fixedly connected to its output end. A mechanical repair arm 303 is mounted on the upper surface of each horizontal plate 302. The cylinders 301 can drive the horizontal plate 302 to move up and down, thereby adjusting the height of the mechanical repair arm 303 to adapt to the repair needs of broken teeth at different positions inside the gearbox. This provides flexible and convenient operation, solving the problem of inconvenient repair in existing devices and improving the repair efficiency. For efficiency, the output ends of the two mechanical repair arms 303 are respectively equipped with a laser welding head 304 and a mechanical gripper 306. An independent power supply 305 electrically connected to the laser welding head 304 is installed on the upper surface of the base frame 1. The mechanical gripper 306 can stably hold the broken tooth fragments, ensuring precise docking between the fragments and the gear body. The laser welding head 304 can complete the welding repair work quickly and efficiently. The independent power supply 305 provides stable power support for the laser welding head 304, ensuring that the welding process is not affected by external power fluctuations, thus improving the repair quality and stability.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Two columns 307 are fixedly connected to both sides of the upper surface of the base frame 1. A fixing plate 308 is fixedly connected to the top of each column 307. The two ends of the two horizontal plates 302 are slidably sleeved on the outer surfaces of the four columns 307. The columns 307 and the fixing plates 308 guide and limit the up and down movement of the horizontal plates 302, preventing the horizontal plates 302 from tilting or shaking during movement, ensuring the stability of the mechanical repair arm 303, and enabling the laser welding head 304 and the mechanical gripper 306 to accurately act on the broken tooth position, further improving the repair accuracy. The main controller 4 is fixedly connected to the bottom surface of the base frame 1. The electrical components inside the support assembly 2 and the repair assembly 3 are all electrically connected to the main controller 4. The main controller 4 can centrally control the electrical components in the support assembly 2 and the repair assembly 3 to work together, realizing the automated linkage of operations such as gearbox clamping and positioning, angle adjustment, and clamping and welding of broken teeth, simplifying the operation process, making the repair work more convenient and efficient, and solving the problem of complex operation of existing devices.

[0036] The implementation principle of this application embodiment is as follows: After the main controller 4 is started, the dual-axis motor 206 in the support assembly 2 starts to work, driving the two lead screws 207 to rotate synchronously. Since the lead screws 207 are respectively inserted into the inner wall of the turntable 201 and the micro bracket 209, the rotation process is stable and without shaking. The moving plate 208, which is threadedly connected to the lead screw 207, slides along the guide post 212, driving the connecting plate 210 and the clamping plate 211 to move closer to each other until the gearbox placed on the support plate 205 is clamped and fixed. The limit block 213 prevents the moving plate 208 from sliding excessively and disengaging from the lead screw 207. Subsequently, the main controller 4 controls the servo motor 204 to operate, driving the worm gear 203 to rotate. Through the worm gear 203 and the worm wheel The meshing transmission of 202 drives the turntable 201 to rotate, and the gearbox angle is adjusted so that the broken tooth position of the medium speed stage is aligned with the repair component 3. During this period, the heat dissipation vent 214 in the turntable 201 dissipates the heat generated by the dual-axis motor 206 in time. During repair, the cylinder 301 pushes the horizontal plate 302 to rise along the column 307 to a suitable height. The fixing plate 308 prevents the horizontal plate 302 from detaching from the column 307. The mechanical repair arm 303 first controls the mechanical gripper 306 to extend into the gearbox to clamp the broken tooth fragment and accurately align it with the tooth root. Then, another mechanical repair arm 303 drives the laser welding head 304 to complete the welding under the power supply of the independent power supply 305. The whole process is linked by the main controller 4 to ensure that the repair operation is efficient and accurate.
