Description

Automatic brushing device for yaw driving bolt Technical Field The utility model relates to the technical field of lubrication and maintenance of yaw drive bolts of wind generating sets, in particular to an automatic brushing device for yaw drive bolts. Background In the field of wind power generation, lubrication and maintenance of yaw drive bolts are important. At present, a mode of manually brushing molybdenum disulfide by using a brush is commonly adopted in the industry to lubricate a yaw driving bolt. However, this traditional manual brushing method has a number of problems, specifically as follows: 1. The brush coating efficiency is low, the manual operation speed is limited, and the maintenance requirement of a large-scale wind generating set is difficult to meet; 2. The brushing length is not easy to control, and the too long or too short brushing condition is easy to occur, so that the lubrication effect is affected; 3. The brush coating is uneven, the lubrication of partial areas is insufficient, and the lubrication of partial areas is excessive, so that the service life of the bolts is reduced, potential safety hazards are possibly caused, and potential risks are brought to the stable operation of the wind generating set. Therefore, an automatic brushing device for yaw drive bolts, which can improve brushing efficiency, precisely control brushing length and ensure brushing uniformity, is needed to solve the technical pain.
