Description

Technical Field

[0001] This utility model relates to the field of wind power equipment maintenance technology, specifically to a wind turbine gearbox overhaul device. Background Technology

[0002] As one of the core components of a wind turbine generator set, the gearbox plays a crucial role. It is responsible for converting the low-speed rotation of the wind turbine into the high-speed rotation of the generator, and its performance directly affects the generator's power generation efficiency and service life. In actual operation, the confined nacelle space cannot provide a stable foundation like the ground, and the power matching and torsional vibration problems of the entire transmission system often manifest in the gearbox, a weak link, making it one of the components with a high failure rate in wind turbine generator sets.

[0003] In existing technologies, the transfer of wind turbine gearboxes often relies on large cranes or manual handling. The former requires specialized equipment and site support, resulting in high transfer costs and site limitations, making it difficult to flexibly switch between different areas and leading to long transfer times. Manual handling is not only inefficient but also poses significant safety risks. Furthermore, the lack of effective limiting and stabilizing measures during transfer makes the gearbox prone to swaying and displacement, potentially causing equipment damage and compromising safety and stability during maintenance.

[0004] Meanwhile, most existing maintenance equipment has limited functionality and cannot be flexibly adjusted to wind turbine gearboxes of different sizes. It struggles to accurately adapt to gearboxes of varying specifications, making fixing and operation extremely difficult for gearboxes of special or diverse sizes, thus limiting maintenance work. Furthermore, existing maintenance equipment lacks sufficient lifting and angle adjustment functions. It cannot meet the needs of maintenance at different heights, is inconvenient to operate, and lacks precise control, easily causing gearbox damage. Regarding angle adjustment, either the relevant function is absent, or the adjustment method is complex and lacks precision, making it difficult to meet the requirements of comprehensive maintenance. This results in numerous difficulties for maintenance personnel when conducting comprehensive inspections and maintenance of the gearboxes, significantly reducing maintenance efficiency.

[0005] Based on this, the present invention designs a wind turbine gearbox maintenance device to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wind turbine gearbox maintenance device.

[0007] The technical solution adopted to solve the above technical problems is:

[0008] A wind turbine gearbox maintenance device includes a mobile platform capable of moving the wind turbine gearbox. The mobile platform is equipped with a lifting assembly for driving the wind turbine gearbox up and down. The mobile platform also has equidistant linear modules for driving the lifting assembly to adapt to wind turbine gearboxes of different lengths. The lifting assembly is equipped with an angle adjustment assembly for adjusting the angle of the wind turbine gearbox. The installation of the wind turbine gearbox on the lifting assembly does not affect the power input to the gearbox's input shaft. The mobile platform is also equipped with limiting components for stabilizing the mobile platform; two sets of limiting components are symmetrically arranged on the left and right sides.

[0009] The angle adjustment components are arranged symmetrically in two sets. The angle adjustment components include a mounting component and a driving component. The mounting component is connected to the lifting component, and the driving component is connected to both the mounting component and the lifting component.

[0010] Through the above technical solution, the mobile platform can transport the wind turbine gearbox, flexibly switching to different areas and greatly saving transport time. The limiting component stabilizes the mobile platform, ensuring safety and stability during maintenance. The equidistant linear module drives the lifting and mounting components to adapt to wind turbine gearboxes of different sizes, fixing them in place. The lifting component raises and lowers the gearbox, while the angle adjustment component adjusts its angle. The lifting and angle adjustment components facilitate maintenance of the wind turbine gearbox.

[0011] Furthermore, the mobile platform includes a mounting base plate and pulleys. Multiple sets of pulleys are fixedly installed on the lower end surface of the mounting base plate, and two sets of equidistant linear modules are fixedly installed in a front-to-back arrangement on the upper end surface of the mounting base plate.

[0012] The above technical solution allows the mounting base plate to be moved via pulleys, facilitating the transport of the wind turbine gearbox.

[0013] Furthermore, the lifting components are arranged symmetrically on the left and right sides. The lifting component on the left side is connected to the slider on the left side of the two sets of equidistant linear modules, and the lifting component on the right side is connected to the slider on the right side of the two sets of equidistant linear modules.

[0014] Furthermore, the lifting assembly includes linear modules, T-shaped steel, connecting plates, and mounting brackets. Two sets of linear modules and T-shaped steel are symmetrically arranged front and rear. The two sets of linear modules are respectively fixedly installed on the inner sidewalls of the two sets of T-shaped steel. The lower end faces of the two sets of T-shaped steel are respectively fixedly connected to the sliders on the front and rear equidistant linear modules. The lower end face of the connecting plate is fixedly connected to the upper end face of the two sets of T-shaped steel. The front end face of the mounting bracket is fixedly connected to the slider on the front linear module, and the rear end face of the mounting bracket is fixedly connected to the slider on the rear linear module. The mounting bracket is connected to the mounting assembly.

[0015] The above technical solution uses two sets of equidistant linear modules driven by an equidistant linear module to adjust the length, which is used to adapt to wind turbine gearboxes of different sizes. The two sets of linear modules drive the mounting frame to adjust the height of the wind turbine gearbox, which is convenient for maintenance.

[0016] Furthermore, the mounting assembly includes a mounting flange and a rotating cylinder. The mounting flange is fixedly mounted on the inner wall of the rotating cylinder, the rotating cylinder is rotatably connected to the mounting bracket, and the rotating cylinder is connected to the drive assembly.

[0017] The above technical solution uses a mounting flange to assemble with the wind turbine gearbox for fixing the wind turbine gearbox. Both the mounting flange and the middle of the rotating cylinder are hollow, allowing the input shaft of the wind turbine gearbox to pass through and connect to the power source.

[0018] Furthermore, the drive assembly includes a drive motor, a mounting block, a first worm, and a first worm wheel. The drive motor and the mounting block are fixedly mounted on the outer end face of the mounting frame. The lower end face of the first worm is fixedly connected to the output end of the drive motor. The first worm is rotatably connected to the mounting block. The first worm is meshed with the first worm wheel. The first worm wheel is fixedly mounted on the outer side wall of the outer end of the rotating drum.

[0019] The above technical solution uses a drive motor to drive the first worm gear, which in turn drives the first worm wheel, which in turn drives the rotating drum. The rotating drum then drives the mounting flange to adjust the angle of the wind turbine gearbox, making it easier for staff to maintain.

[0020] Furthermore, the limiting assembly includes a drive turntable, a second worm gear, a second worm wheel, a threaded rod, a slide rod, a movable plate, and support feet. The drive turntable is fixedly connected to the outer end of the second worm gear. The second worm gear is rotatably mounted on a mounting lug on the mounting base plate. The second worm gear is meshed with the second worm wheel, and the second worm wheel is rotatably connected to the mounting base plate. The upper end face of the threaded rod is fixedly connected to the lower end face of the second worm wheel. Two sets of slide rods are arranged in a front-to-back configuration, and the upper ends of both sets of slide rods are fixedly connected to the lower end face of the mounting base plate. The threaded rod is threadedly connected to the movable plate, and the slide rod is slidably connected to the movable plate. Two sets of support feet are arranged in a front-to-back configuration, and the upper end faces of both sets of support feet are fixedly connected to the lower end face of the movable plate.

[0021] Through the above technical solution, the drive turntable drives the second worm gear, the second worm gear drives the second worm wheel, the second worm wheel drives the threaded rod, and the threaded rod drives the moving plate to descend. The descent of the moving plate causes the support feet to fit against the ground for support and limitation. When the moving plate descends, it is guided by the slide rod, which realizes the limitation of the moving platform and enables it to be fixed during the maintenance of the wind turbine gearbox, thus improving safety.

[0022] Furthermore, a limiting plate is fixedly installed on the lower end face of the threaded rod.

[0023] The above technical solution uses a limiting plate to limit the movement of the plate.

[0024] The beneficial effects of this utility model are as follows: (1) The mobile platform can drive the wind turbine gearbox to be transported, and can be flexibly switched to different areas, which greatly saves the transport time. The mobile platform is limited and stabilized by the limit component, which ensures safety and stability during maintenance. (2) The lifting component and the installation component driven by the equidistant linear module can be adapted to wind turbine gearboxes of different sizes, and wind turbine gearboxes of different sizes can be fixed. The lifting component drives the wind turbine gearbox to be raised and lowered, and the angle adjustment component drives the wind turbine gearbox to be angled. The lifting component and the angle adjustment component facilitate the maintenance of the wind turbine gearbox. Attached Figure Description
