Description

Technical Field

[0001] The utility model relates to the technical field of carbon brush dust cleaning, in particular to a rotor carbon brush dust cleaning device. Background Art

[0002] The main component of the carbon brush is graphite, which is constantly worn out by friction with the collector ring during the operation of the generator. Therefore, it needs to be replaced regularly according to the wear. The contact surface of the spare carbon brush is flat and needs to be polished before installation. The generator maintenance regulations stipulate that the contact surface between the new carbon brush and the slip ring should reach more than 3 / 4. If the number of carbon brushes replaced is large and the contact surface is not tight enough, it will cause overheating and even arc damage to the collector ring. Traditionally, the contact surface of the carbon brush is processed mainly by manual polishing. Use one hand to press the sandpaper on the circumference of the collector ring, and use the other hand to hold the carbon brush and polish it back and forth along the surface of the collector ring repeatedly until its contact surface meets the requirements of the regulations.

[0003] After searching, I found the prior art (publication number: CN215617357U), which records "a carbon brush grinding device that is convenient for handling dust, belonging to the field of generator carbon brush processing, including a grinding box, a dust collection box installed above the grinding box, a dust suction pipe installed on the lower side of the dust collection box, the lower end of the dust suction pipe located in the grinding box, a fan installed on the side of the dust collection box, and an air outlet provided on the upper side of the dust collection box; the fan can guide dust from the dust suction pipe into the dust collection box, and the dust collection box located above the grinding box collects the dust. The dust can be discharged by regularly cleaning and replacing the dust collection box, thereby solving the problem of dust accumulation in the grinding box in the prior art, which affects the normal operation of the mechanism."

[0004] Although the carbon brush grinding device in the prior art is easy to handle dust, it can handle the carbon brush grinding wind dust, but there are still some shortcomings: the existing carbon brush grinding dust handling device uses a fan to drive the air flow inside the collection box to achieve a negative pressure effect inside the grinding box, and the air blown out by the fan is first affected by the resistance of the wind bag, and then part of the air may be blown into the grinding box, which leads to a deviation in the negative pressure dust collection effect. Secondly, it is more troublesome to handle the dust collected inside the dust collection box. At the same time, there is a phenomenon that the dust adsorbed on the inner wall of the collection box due to static electricity is difficult to clean. Utility Model Content

[0010] Furthermore, the brush rod assembly includes a cross bar, and both ends of the cross bar are connected to vertical bars, and the middle of the cross bar is connected to a second drive shaft, while the upper end of the second drive shaft passes through the cross bar and is rotatably connected to the solid plate.
