Description

Technical Field

[0001] This invention relates to the field of wind turbine main gearbox technology, and in particular to a wind turbine main gearbox with automatic positioning function. Background Art

[0002] With the continued growth of global demand for clean energy, wind power, as a green and environmentally friendly renewable energy source, has been widely applied and rapidly developed. The main gearbox of a wind turbine, as the core transmission component of a wind turbine generator set, primarily functions to transmit the low-speed, high-torque power generated by the wind turbine under wind force to the generator, achieving efficient conversion of mechanical energy into electrical energy. During the installation and operation of wind power equipment, the installation accuracy of the main gearbox has a crucial impact on the performance and reliability of the entire unit.

[0003] Currently, the traditional installation process of wind turbine main gearboxes mainly relies on manual operation and experience-based judgment, which presents many problems that urgently need to be solved. On the one hand, the efficiency of manual positioning and adjustment is extremely low. In the construction of large-scale wind farms, the installation of a large number of wind turbine main gearboxes requires a significant amount of manpower and time, seriously affecting the project progress. On the other hand, due to the lack of precise measurement and positioning methods, installation deviations are difficult to avoid, resulting in uneven loads on the gearbox during operation. This not only accelerates the wear of key components such as gears and bearings, causing abnormal vibration and noise, and reducing transmission efficiency, but may also lead to fatigue damage of internal parts of the gearbox, significantly shortening the service life of the wind turbine main gearbox and increasing the frequency and cost of equipment maintenance. Therefore, we propose a wind turbine main gearbox with automatic positioning function to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wind turbine main gearbox with automatic positioning function.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] This application discloses a fan main gearbox with automatic positioning function.

[0032] Reference Figure 1-8A fan main gearbox with automatic positioning function includes a base 101. A longitudinal adjustment plate 102 is slidably installed on the top of the base 101. A transverse adjustment plate 103 is slidably installed on the top of the longitudinal adjustment plate 102. Two fixing brackets 104 are fixedly installed on the top of the transverse adjustment plate 103, and the same fan main gearbox body 105 is installed on the two fixing brackets 104. A fixing plate 201 is fixedly installed on the rear side of the base 101. A push rod motor 202 is fixedly installed on the rear side of the fixing plate 201. The output shaft of the push rod motor 202 is fixedly connected to the longitudinal adjustment plate 102. A vertical plate 203 is fixedly installed on one side of the longitudinal adjustment plate 102. A push rod motor 204 is fixedly installed on one side of the vertical plate 203. The output shaft of the push rod motor 204 is fixedly connected to the transverse adjustment plate 103.

[0033] A rectangular hole 301 is provided at the top of the longitudinal adjustment plate 102. A longitudinal measuring plate 303 is fixedly installed at the top of the base 101, and the longitudinal measuring plate 303 passes through the rectangular hole 301. A guide hole 302 is provided at the top of the transverse adjustment plate 103. A transverse measuring plate 304 is fixedly installed at the top of the longitudinal measuring plate 303. A rotating disk 305 is rotatably installed at the top of the base 101. A mounting plate 306 is fixedly installed at the top of the rotating disk 305. A device is fixedly installed on one side of the mounting plate 306 to the transverse measuring plate 304. 04. A laser rangefinder 307 adapted to the longitudinal measuring plate 303 has a storage groove 401 at the bottom of the base 101. Rectangular grooves 403 are provided on the inner walls of both sides of the storage groove 401. The same rectangular seat 404 is slidably installed in the two rectangular grooves 403. A drive mechanism is provided between the rectangular seat 404 and the rotating disk 305. An installation groove 407 is provided at the bottom of the base 101. An electric push rod 408 is installed in the installation groove 407. The output shaft of the electric push rod 408 is fixedly connected to the rectangular seat 404.

[0034] In this embodiment, the driving mechanism includes a driving rack 405, a rotating shaft 402, and a driving gear 406. The driving rack 405 is fixedly installed on the front side of the rectangular base 404, and the rotating shaft 402 is fixedly installed on the bottom of the rotating disk 305. The rotating shaft 402 is rotatably connected to the base 101, and the bottom end of the rotating shaft 402 extends into the receiving groove 401 and is fixedly installed with the driving gear 406 that meshes with the driving rack 405. Through the meshing transmission of the driving rack 405 and the driving gear 406, the linear motion of the rectangular base 404 is converted into the rotational motion of the rotating disk 305, thereby realizing the switching of the measurement direction of the laser rangefinder 307, providing a measurement basis for the longitudinal and lateral positioning of the main gearbox body 105 of the wind turbine, and ensuring the accuracy of positioning adjustment.

[0035] In this embodiment, a movable hole 502 is provided on the top inner wall of the storage slot 401. A movable seat 503 is slidably installed in the movable hole 502. A fixing mechanism is provided between the movable seat 503 and the longitudinal adjusting plate 102. The fixing mechanism includes a fixing gear 504 and a fixing rack 501. The fixing gear 504 is fixedly installed on the top of the movable seat 503, and the fixing rack 501 is fixedly installed on one side inner wall of the rectangular hole 301. The fixing gear 504 and the fixing rack 501 are adapted to each other. When the fixing gear 504 and the fixing rack 501 mesh, the movement of the longitudinal adjusting plate 102 can be effectively restricted, enhancing the stability of the main gearbox of the fan in the longitudinal direction, preventing positional deviation due to vibration and other factors, and ensuring the reliability of equipment operation.

[0036] In this embodiment, the top of the longitudinal adjustment plate 102 is provided with a connecting hole 601, and the inner wall of the top of the receiving groove 401 is provided with a rotating hole 602 that communicates with the connecting hole. A rotating seat 603 is rotatably installed in the rotating hole 602, and a driven gear 609 that meshes with the drive rack 405 is fixedly installed at the bottom of the rotating seat 603. The rotating seat 603 is provided with an engagement mechanism that connects to the transverse adjustment plate 103. The movement of the drive rack 405 drives the driven gear 609 to rotate, thereby controlling the working state of the engagement mechanism, realizing automatic unlocking and locking of the transverse adjustment plate 103, simplifying the operation process, and improving the automation and efficiency of transverse positioning adjustment.

[0037] In this embodiment, the engagement mechanism includes a threaded groove 604, a threaded rod 605, a horizontal plate 606, a pin 607, and a slot 608. The threaded groove 604 is formed on the top of the rotating seat 603. The threaded rod 605 is threadedly installed in the threaded groove 604. The horizontal plate 606 is fixedly installed at the top of the threaded rod 605. The pin 607 is fixedly installed at the top of the horizontal plate 606. Multiple slots 608 are evenly spaced at the bottom of the transverse adjustment plate 103, and the pins 607 are adapted to the corresponding slots 608. By raising and lowering the threaded rod 605 in the threaded groove 604, the engagement and disengagement of the pins 607 and slots 608 are precisely controlled, achieving accurate positioning and reliable fixation of the transverse adjustment plate 103, and ensuring the installation accuracy of the main gearbox of the wind turbine in the transverse direction.

[0038] In this embodiment, a limiting rod 702 is fixedly installed at the bottom of the horizontal plate 606, and a limiting hole 701 communicating with the connecting hole 601 is provided on the top inner wall of the receiving groove 401, and the limiting rod 702 is slidably installed in the corresponding limiting hole 701. The cooperation between the limiting rod 702 and the limiting hole 701 effectively restricts the movement direction of the horizontal plate 606, prevents the pin 607 from shifting during the lifting process, ensures that the pin 607 can be accurately inserted into and pulled out of the slot 608, and improves the stability and reliability of the engagement mechanism.

[0039] In this embodiment, the top of the base 101 has two T-shaped sliding grooves 106, and the bottom of the longitudinal adjustment plate 102 has two T-shaped slide blocks 107 fixedly installed, with the T-shaped slide blocks 107 slidably connected to the corresponding T-shaped sliding grooves 106. The top of the longitudinal adjustment plate 102 has two T-shaped sliding grooves 108, and the bottom of the transverse adjustment plate 103 has two T-shaped slide blocks 109 fixedly installed, with the T-shaped slide blocks 109 slidably connected to the corresponding T-shaped sliding grooves 108. The cooperative design of the T-shaped sliding grooves and slide blocks provides precise guidance for the movement of the longitudinal adjustment plate 102 and the transverse adjustment plate 103.

[0040] In this embodiment, a controller is installed on the front side of the base 101, and the push rod motor 202, the push rod motor 204, the electric push rod 408, and the laser rangefinder 307 are all electrically connected to the controller. As the control core of the equipment, the controller realizes unified coordination and intelligent control of various components. The operator only needs to set parameters, and the equipment can automatically complete the positioning adjustment, reducing the difficulty of operation and improving the degree of automation and work efficiency.

[0041] In this invention, the base 101 and the fixing frame 104 can support the main gearbox body 105 of the wind turbine. When there is a deviation in the installation position of the main gearbox body 105, the controller can start and stop the push rod motor. The push rod motor can drive the rectangular seat 404 to move by a set length. The rectangular seat 404 drives the drive gear 406 to rotate through the drive rack 405. The drive gear 406 drives the rotating disk 305 to rotate counterclockwise by 90 degrees through the rotating shaft 402, so that the light from the laser rangefinder 307 can be projected onto the longitudinal measuring plate 303. The movement of the rectangular seat 404 can drive the moving seat 503 and the fixed gear 504 to move. The movement causes the fixed gear 504 to separate from the fixed rack 501, thereby releasing the fixation of the longitudinal adjustment. The controller can activate the push rod motor 202, which drives the longitudinal adjustment plate 102 to move forward and backward. The longitudinal adjustment plate 102, through the transverse adjustment plate 103, drives the main gearbox body 105 of the fan to adjust its position in the forward and backward direction. The laser rangefinder 307 can detect the distance moved, improving the accuracy of the forward and backward adjustment of the main gearbox body 105. This achieves the purpose of positioning and adjusting the main gearbox body 105 in the forward and backward direction. The start / stop electric actuator 408 can again move the rectangular base 404 a set distance. At this time, the rectangular base 404, through the drive rack 405, can again drive the rotating gear to rotate 90 degrees. The rotating gear, through the rotating shaft 402 and the rotating disk 305, drives the laser rangefinder 307 to rotate, so that the light from the laser rangefinder 307 can be projected onto the horizontal measuring plate 304. The two movements of the rectangular base 404 drive the driven gear 609 to rotate through the drive rack 405. The driven gear 609 can drive the rotating shaft to rotate. The rotating shaft, through the threaded groove 604, drives the threaded rod 605 to move downward. The threaded rod 605 can drive... The horizontal plate 606 and the pin 607 move downwards, allowing the pin 607 to disengage from the corresponding slot 608, thus releasing the horizontal adjustment plate 103. The controller starts the push rod motor 204, which drives the horizontal adjustment plate 103 to move left and right. The horizontal adjustment plate 103, through the fixing frame 104, can drive the main gearbox body 105 of the fan to move. The laser rangefinder 307 can detect the distance of movement, improving the accuracy of the left and right adjustment of the main gearbox body 105 of the fan, and achieving the purpose of positioning and adjusting the main gearbox body 105 of the fan in the front and back directions.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
