Description

Technical Field

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

[0002] An existing patent (publication number: CN220265047U) proposes a disassembly fixture for a wind turbine yaw and pitch reducer, including a base. A bolt is installed through the top surface of the base, and a support foot is rotatably installed on the side of the base. A fixing device is set on the top of the base. However, this device, "the fixing device is set on the top of the base, and the support arm is connected to the top surface of the base," has a fixed position, making it difficult to make fine adjustments to the lifting position during hoisting, which affects the convenience and speed of overall repair. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a wind turbine yaw reducer and mounting base repair device. By rotating the adjusting seat and driving the nut, the longitudinal position of the horizontal support column can be adjusted. The horizontal drive motor drives the horizontal adjusting screw to rotate, thereby adjusting the lateral position of the horizontal adjusting slider. This allows for position correction during the hoisting of the wind turbine yaw reducer, enabling real-time position correction during the repair process and making the repair process more convenient and faster.

[0004] The objective of this utility model is achieved through the following technical solution: A repair device for a wind turbine yaw reducer and mounting base includes a bottom support base, a bottom adjusting base, a longitudinal adjusting screw, a longitudinal adjusting slider, and a transverse adjusting screw. The bottom support base has a bottom support base platform at its top, and the bottom support base platform has an adjusting base connecting groove inside. The adjusting base connecting groove is adapted to the bottom adjusting base and is connected to it. The bottom adjusting base slides inside the adjusting base connecting groove. The adjusting base connecting groove has an adjusting base positioning rod inside. The adjusting base connecting groove is rotatably connected to the adjusting base driving screw. The adjusting base driving screw has an adjusting base driving nut on its side. The bottom adjusting base has an adjusting base positioning groove on one side, which is adapted to the adjusting base positioning rod and is connected to it. The adjusting base positioning groove slides outside the adjusting base positioning rod. The bottom adjusting base has an adjusting base driving screw groove on the other side.

[0005] The adjusting seat drive screw groove corresponds to the adjusting seat drive screw, and the adjusting seat drive screw groove and the adjusting seat drive screw are threadedly connected. The top of the bottom adjusting seat has a longitudinal support column, and the longitudinal support column has a longitudinal support slide groove inside. The longitudinal support slide groove is rotatably connected to the longitudinal adjusting screw. The bottom of the bottom adjusting seat is fixedly connected to a longitudinal drive motor. The transmission shaft of the longitudinal drive motor is fixedly connected to the longitudinal adjusting screw. The longitudinal adjusting slider is adapted to the longitudinal support slide groove, and the longitudinal adjusting slider is connected to the longitudinal support slide groove. The longitudinal adjusting slider slides inside the longitudinal support slide groove.

[0006] The longitudinal adjusting slider is internally threadedly connected to the longitudinal adjusting screw. The longitudinal adjusting slider has hoisting rope mounting platforms on both sides. A transverse supporting column is located at the top of the longitudinal supporting column. The transverse supporting column has a transverse supporting groove inside, which is rotatably connected to the transverse adjusting screw. The transverse supporting groove is adapted to the transverse adjusting slider and connects to it. The transverse adjusting slider slides within the transverse supporting groove. A hoisting rope positioning cylinder is located at the bottom of the transverse adjusting slider. The transverse adjusting slider is internally threadedly connected to the transverse adjusting screw, and both sides of the transverse adjusting slider are rotatably connected to hoisting wheels.

[0007] Beneficial effects: 1. When repairing and maintaining the wind turbine yaw reducer and mounting base, the wind turbine yaw reducer needs to be lifted. By rotating the adjusting seat drive nut, the longitudinal position of the horizontal support column can be adjusted. The horizontal drive motor drives the horizontal adjusting screw to rotate, which can adjust the lateral position of the horizontal adjusting slider. This completes the position correction when lifting the wind turbine yaw reducer, allowing for real-time position correction during the repair process, making the repair process more convenient and faster.

[0008] 2. The horizontal adjustment slider and the horizontal adjustment screw of this utility model are connected by threads, and the vertical adjustment slider and the vertical adjustment screw are connected by threads. The threaded connection has good self-locking properties, so that the vertical adjustment slider and the horizontal adjustment slider will not be easily affected by external factors and will not move after stopping at any position, thus ensuring the stability during lifting.

[0009] 3. In this utility model, the lifting rope passes through the lifting rope positioning cylinder and connects to the lifting lug of the reducer, so that the lifting rope always corresponds to the intermediate transition wheel and the lifting wheel during the movement, and will not easily detach from the intermediate transition wheel and the lifting wheel, thus ensuring the stability of the connection between the lifting rope and the intermediate transition wheel and the lifting wheel.

[0010] 4. The bottom of the hoisting rope positioning cylinder of this utility model is rounded and chamfered, so that when the hoisting rope slides inside the hoisting rope positioning cylinder, it will not cause severe friction with the corners of the hoisting rope positioning cylinder and damage the hoisting rope, thereby ensuring the service life of the hoisting rope.
