The top of the reinforcing block 112 is fixedly connected to the bottom of the rotating disk 120. One side of the bottom of the reinforcing block 112 is inclined.

A controller that works with the servo motor 143 is provided on the outer side of the base 110. A threaded rod 150 is rotatably installed on the top of the inner wall of the base 110. A sliding plate 151 is threaded on the threaded rod 150. The lifting frame 130 is U-shaped. The bottom two sides of the lifting frame 130 slide through the top of the base 110 and are fixedly connected to the top of the sliding plate 151. An adjustment component is installed at the bottom of the threaded rod 150. A guide rod 152 is fixedly installed between the two sides of the inner wall of the base 110.

[0025] In some specific implementations, a connecting wire is provided at the bottom of the carbon brush 132, and round holes that mate with the connecting wire are provided on the lifting frame 130 and the support plate 131. After the support plate 131 is inserted into the groove, it is fixedly connected to the lifting frame 130 by bolts 133. The diameter of the round hole is larger than the diameter of the connecting wire, so as to facilitate connection with an external power source through the connecting wire to energize the carbon brush 132.
[0026] In some specific embodiments, the adjusting assembly includes a second rotating shaft 153, a second worm gear 154, and a second worm 155. The second rotating shaft 153 is fixedly mounted at the bottom end of the threaded rod 150, and the second worm gear 154 is fixedly mounted on the outer side of the second rotating shaft 153. The second worm 155 is rotatably mounted on one side of the inner wall of the base 110. The second worm gear 154 and the second worm 155 are connected by a transmission. A third rotating shaft is fixedly mounted at one end of the second worm 155. One end of the third rotating shaft passes through one side of the base 110 and is fixedly mounted with a handle 156. The bottom end of the rotating shaft 153 is rotatably connected to the bottom end of the inner wall of the base 110. A vertical plate is fixedly installed on one side of the bottom end of the inner wall of the base 110. One end of the second worm gear 155 is rotatably connected to one side of the vertical plate.

The outer side of the lifting frame 130 is slidably connected to the inner wall of the protective frame 157. When the top of the inner wall of the protective frame 157 is in contact with the top of the lifting frame 130, the brush head of the carbon brush 132 slides against the conductive ring 122. The protective frame 157 limits the lifting height of the lifting frame 130 to prevent the brush head of the carbon brush 132 from being squeezed and damaged by the conductive ring 122.
[0028] Working principle: When replacing carbon brush 132, rotating handle 156 drives second rotating shaft 153 to rotate through the cooperation of second worm gear 155 and second worm wheel 154. The rotation of second rotating shaft 153 drives slide plate 151 to move down through threaded rod 150. The movement of slide plate 151 drives lifting frame 130 to move down until carbon brush 132 is separated from conductive ring 122 at a distance that facilitates disassembly. After removing bolt 133, carbon brush 132 and support plate 131 can be removed together for replacement. After replacement, it is fixed again with bolt 133. After fixing, rotate handle 156 until brush head of carbon brush 132 abuts against conductive ring 122. When rotation detection is required, simply start servo motor 143. Servo motor 143 drives first rotating shaft 140 to rotate through the cooperation of first worm wheel 141 and first worm gear 142. The rotation of first rotating shaft 140 drives rotating disk 120 through support shaft 111 to achieve rotation adjustment.
