Description

Technical Field

[0001] This utility model relates to the technical field of double-arm brush box inspection equipment, specifically an inspection fixture for a wind-powered riding double-arm brush box. Background Technology

[0002] The function of the brush holder is to apply pressure to the carbon brushes, which slide in contact with the surface of the slip ring, using a constant force spring, thus ensuring stable current conduction between the stationary and rotating components. For wind turbines, both carbon brushes and brush holders are crucial components. The brush holder is assembled from four parts: the terminal block, the connecting block, and the brush box itself. The first four parts are manufactured using paraffin precision casting and then machined. The resulting sand-cast surfaces are rough and difficult to position, making proper inspection of the brush holder a critical issue.

[0003] However, in the existing technology, after the brush box is fixed to the base plate with bolts, the inspection worker checks the angle and flatness of the brush box by inserting a plug into the brush box. When the plug cannot be inserted into the brush box, the worker needs to manually measure it with a steel ruler. At this time, the worker has to bend over to use the steel ruler to measure it. The worker's long-term repeated bending and standing up leads to wear and tear on the waist and affects the worker's health. Therefore, a wind-powered riding double-arm brush box inspection fixture is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an inspection fixture for a wind-powered riding double-arm brush box. By setting up a lifting mechanism to drive the brush box body to rise and fall, the worker does not need to bend over to inspect, which saves more time and effort, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An inspection fixture for a wind-powered riding double-arm brush box includes a base, a lifting mechanism, and a brush box body. The lifting mechanism is located on the top of the base, and the brush box body is located inside the lifting mechanism. The lifting mechanism includes a base plate and a lifting plate. The base plate is rotatably mounted above the lifting plate. The brush box body is mounted on the top surface of the base plate. Both ends of the lifting plate are located on the top surface of the base and are equipped with drive components for adjusting the lifting plate by lifting. Below the base plate, there is also a rotating assembly for driving the base plate to rotate the brush box body above it.

[0006] Preferably, the drive assembly includes a vertical frame and a threaded rod. The vertical frames are symmetrically arranged on both sides of the base surface. The top end of the threaded rod passes through the top surface of one of the vertical frames and is keyed to the output shaft of a servo motor fixedly installed on the top surface of the vertical frame. The bottom end of the threaded rod is rotatably disposed on the base surface. One end of the lifting plate is threadedly sleeved on the outer arc surface of the threaded rod.

[0007] Preferably, a guide rod is fixedly provided between the inner top surface of another vertical frame and the surface of the base, and the other end of the lifting plate is slidably sleeved on the outer arc surface of the guide rod.

[0008] Preferably, the rotating assembly includes a connecting rod and a rotary motor. The top end of the connecting rod is fixedly installed to the bottom surface of the base plate, and the bottom end of the connecting rod passes through the lifting plate and is keyed to the output shaft of the rotary motor fixedly installed on the bottom surface of the lifting plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: An inspection fixture for a wind-powered riding double-arm brush box includes a base 1, a lifting mechanism 3, and a brush box body 6. The lifting mechanism 3 is located on the top of the base 1, and the brush box body 6 is located inside the lifting mechanism 3. The lifting mechanism 3 includes a base plate 4 and a lifting plate 14. The base plate 4 is rotatably disposed above the lifting plate 14. The brush box body 6 is disposed on the top surface of the base plate 4. Both ends of the lifting plate 14 are located on the top surface of the base 1 and are also provided with drive components for driving the lifting plate 14 to perform lifting and adjusting. Below the base plate 4, there is also a rotating component for driving the base plate 4 to rotate the brush box body 6 above.

[0018] By setting up a lifting mechanism 3 to drive the lifting plate 14 to rise and fall, the lifting plate 14 drives the brush box body 6 installed on the top surface of the bottom plate 4 to rise and fall, so that the inspection workers can measure and inspect the inside of the brush box body 6 by holding a steel ruler. The lifting mechanism 3 can be controlled by an external controller to raise and lower, without the need for workers to repeatedly bend over and cause physical injury.

[0019] The drive assembly includes a vertical frame 9 and a threaded rod 10. The vertical frames 9 are symmetrically arranged on both sides of the surface of the base 1. The top end of the threaded rod 10 passes through the top surface of one of the vertical frames 9 and is keyed to the output shaft of the servo motor 11 fixedly installed on the top surface of the vertical frame 9. The bottom end of the threaded rod 10 is rotatably arranged on the surface of the base 1. One end of the lifting plate 14 is threadedly sleeved on the outer arc surface of the threaded rod 10.

[0020] A servo motor 11 drives the threaded rod 10 inside one of the vertical frames 9 to rotate. A guide rod 13 is fixed between the inner top surface of the other vertical frame 9 and the surface of the base 1. The other end of the lifting plate 14 is slidably sleeved on the outer arc surface of the guide rod 13, so that the lifting plate 14 can drive the brush box body 6 above to rise and fall along the outer arc surface of the guide rod 13 under the rotation of the threaded rod 10, so that the inspection worker can perform internal measurement without the worker having to bend over to inspect.

[0021] The rotating assembly includes a connecting rod 12 and a rotary motor 16. The top end of the connecting rod 12 is fixedly installed on the bottom surface of the base plate 4, and the bottom end of the connecting rod 12 passes through the lifting plate 14 and is keyed to the output shaft of the rotary motor 16 fixedly installed on the bottom surface of the lifting plate 14.

[0022] A connecting rod 12 is provided on the bottom surface of the base plate 4, and the bottom end of the connecting rod 12 passes through the lifting plate 14 and is keyed to the output shaft of the rotary motor 16 provided on the bottom surface of the lifting plate 14. At the same time, a rotating groove 15 is also opened on the surface of the lifting plate 14 outside the connecting rod 12. Multiple support columns 18 are provided on the bottom surface of the base plate 4 outside the connecting rod 12. The bottom ends of the support columns 18 are slidably connected to the inner wall of the rotating groove 15, so that the rotary motor 16 can be started by an external controller, thereby driving the base plate 4 to rotate. This allows the support columns 18 to slide on the inner wall of the rotating groove 15, supporting the base plate 4 and facilitating the rotation of the brush box body 6. This further facilitates the inspection workers to perform multi-angle inspection.

[0023] A through groove 17 is provided on the surface of the base 1 directly below the rotary motor 16. The inner wall of the through groove 17 does not contact the rotary motor 16. The through groove 17 is also provided on the surface of the base 1, and the inner wall of the through groove 17 does not contact the rotary motor 16, so as to protect the rotary motor 16 and prevent the rotary motor 16 from colliding with the surface of the base 1 and causing damage to the equipment.

[0024] An angle detection block 5 for detecting the angle of the brush box body 6 is provided on one side of the top surface of the base plate 4. A fixing post 7 is also provided on the top surface of the base plate 4 inside the angle detection block 5. The brush box body 6 is sleeved on the outside of the fixing post 7.
