Description

Technical Field

[0001] This utility model relates to the field of wind turbine generators, and in particular to a repair device for a wind turbine yaw reducer. Background Technology

[0002] An existing patent (publication number: CN221821746U) discloses a repair device for a wind turbine yaw reducer. It includes an electric hoist, a cantilever beam fixedly connected to the electric hoist, and a support frame. The cantilever beam is a square tube structure with an internal extension arm. Both the cantilever beam and the extension arm have openings on their sides and are connected to each other by pins. The support frame includes a base, a column, and a crossbeam, with both ends of the column welded to the base and the crossbeam respectively. The cantilever beam is rotatably connected to the support frame, allowing it to rotate horizontally below the base. However, this device relies on the electric hoist at the front of the base for repair and lifting operations. Since the base needs to be installed on a ceiling, the device cannot be installed and used if the site does not have ceiling installation conditions, thus presenting certain limitations. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a wind turbine yaw reducer repair device. After the equipment frame is moved to the suspension position, the support arm is raised and lowered by a cylinder on the side of the equipment frame. This causes the support arm to lift the universal wheels at the bottom of the support rod, while the toothed plate at the bottom of the equipment frame contacts the ground to increase friction. Ground nails are driven into the ground to increase the support force of the equipment. The device can be used without the need for the installation of a canopy, thereby increasing the adaptability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution: A repair device for a wind turbine yaw reducer includes an equipment frame, a push rod, a roller shaft, an angle seat, an angle shaft, a drive box, a worm gear, and a worm motor. The rear of the equipment frame is fixedly connected to the push rod, and the lower part of the equipment frame is fixedly connected to a toothed plate. The lower part of the equipment frame has a ground spike groove that is adapted to a ground spike, and the ground spike is inserted into the ground spike groove. The side of the equipment frame has a positioning groove that is adapted to a support rod, and the support rod is connected to the positioning groove and is located inside the positioning groove. The sliding mechanism includes a lower support rod fixedly connected to a caster wheel, an upper support rod fixedly connected to a support arm, a side of the equipment frame fixedly connected to a cylinder, an upper cylinder fixedly connected to a support arm, an upper turntable frame fixedly connected to a turntable frame, an upper turntable frame with a turntable shaft groove that is compatible with the turntable shaft, the turntable shaft groove connecting to the turntable shaft, the turntable shaft rotating inside the turntable shaft groove, a lower turntable frame fixedly connected to a turntable motor, a turntable motor output shaft fixedly connected to the turntable shaft, and a side of the turntable frame with a support roller shaft groove.

[0005] The roller shaft groove is fixedly connected to the roller shaft, the roller shaft is adapted to the roller, the roller shaft is connected to the roller, the roller rotates on the side of the roller shaft, the upper part of the turntable shaft is fixedly connected to the turntable, the roller rotates on the side of the turntable, and the upper part of the turntable is fixedly connected to the angle bracket.

[0006] The angle seat is fixedly connected to the angle shaft on the side, the angle frame is adapted to the angle shaft, the angle frame is connected to the angle shaft, the angle shaft rotates on the side of the angle frame, the rear of the angle seat is fixedly connected to the lifting hydraulic device, and the side of the angle frame is fixedly connected to the drive box. Beneficial effects

[0007] 1. During the use of this utility model wind turbine yaw reducer repair device, after the equipment frame is moved to the suspension position, the cylinder on the side of the equipment frame drives the support arm to rise and fall. At the same time, the support arm drives the universal wheel at the bottom of the support rod to lift, and the toothed plate at the bottom of the equipment frame contacts the ground to increase friction. Ground nails are driven into the ground to increase the support force of the equipment. It can be used without the need to install the canopy, thereby increasing the adaptability of the equipment.

[0008] 2. During the use of this utility model wind turbine yaw reducer repair device, the turntable motor at the bottom of the turntable frame drives the winch at the top of the turntable to adjust the direction, and in conjunction with the worm motor on the side of the drive box to drive the worm to rotate, so that the worm drives the worm wheel on the side of the drive box to rotate. At the same time, the drive box drives the winch at the front of the angle seat to adjust the elevation angle. During this process, the equipment does not need to be moved or adjusted, which makes it convenient for workers to carry out repair and hoisting operations on the yaw reducer.

[0009] 3. During the use of this utility model wind turbine yaw reducer repair device, the worm motor drives the worm to drive the worm wheel to rotate, which in turn drives the drive box to rotate. Because the transmission principle of the worm and worm wheel has a self-locking function, the device maintains the adjusted angle during operation, thereby enhancing the stability of the device.
