[0038] Place the wind turbine bearing between the two sets of protective pressure plates, and then push the two sets of sleeves toward the middle to compress the No. 1 spring 303. When the two sets of sleeves 302 are close together, the two sets of rotating shafts 305 are driven to move closer to each other through the support rod 304, so that the rotating shaft 305 pushes the protective pressure plate 306 to move closer to each other, so that the middle protrusion of the protective pressure plate 306 extends into the inner ring of the bearing, and the outer ring of the protective pressure plate 306 is pressed between the inner and outer rings of the bearing, thereby preventing the spraying material from entering the bearing through the gap between the inner and outer rings and causing damage to the roller. In the process of the two sets of sleeves 302 moving closer to each other, the side wall of the sleeve 302 contacts the inclined block 309, so that the inclined block 309 is pushed and slid, and the sliding of the inclined block 309 drives the top The rod 308 slides, causing the top rod 308 to compress the No. 2 spring 310. After the sleeve 302 completely passes the bevel block 309, the No. 2 spring 310 pushes the top rod 308 to reset, thereby resetting the bevel block 309. At this time, the slide is blocked by the bevel block 309 and cannot be pushed back to reset by the No. 1 spring 303. At this time, the wind turbine bearing is fixed and protected. At this time, the bottom end of the outer wall of the wind turbine bearing is attached to the outer wall of the rubber wheel 402, and then the motor 201 rotates to drive the No. 1 gear 202 to rotate, the No. 1 gear 202 drives the No. 2 gear 204 to rotate, the No. 2 gear 204 drives the threaded rod 203 to rotate, the threaded rod 203 pushes the slider 205 to slide, and the slider 205 drives the protective mechanism 3 to move, thereby driving the wind turbine bearing to move.

[0039] Please refer to Figure 1-8The bracket 307 includes a connecting rod 3071, a threaded sleeve 3072, a ball head 3073, and a sleeve 3074. One end of the connecting rod 3071 is fixedly connected to the side wall of the support rod 304, and the other end of the connecting rod 3071 is threadedly connected to the threaded sleeve 3072. The other end of the connecting rod 3071 is slidably connected to the ball head 3073 located inside the threaded sleeve 3072. The opening of the threaded sleeve 3072 abuts against the outer wall of the ball head 3073. The outer wall of the ball head 3073 is fixedly connected to the sleeve 3074 extending to the outside of the threaded sleeve 3072. The side wall of the sleeve 3074 is provided with an opening, and the opening is threadedly connected with a bolt. The rotation mechanism 4 includes It includes a support plate 401, a rubber wheel 402, a rack 403, a third gear 404, and a pulley group 405. The top of the base 301 is fixedly connected to the support plate 401, the top of the support plate 401 is rotatably connected to two sets of rubber wheels 402, the top of the shell 1 is fixedly connected to the rack 403, the support plate 401 is slidably connected to the side wall of the rack 403, the inner wall of the support plate 401 is rotatably connected to the third gear 404, the third gear 404 is meshed with the rack 403, and the inner wall of the support plate 401 is provided with a pulley group 405, one end of the pulley group 405 is connected to the side wall of the third gear 404, and the other end of the pulley group 405 is connected to the rubber wheel 402.

[0040] By inserting the spray gun into the inside of the sleeve 3074, and then turning the bolt so that the thread drives several sets to tighten, thereby fixing the spray gun, and then turning the sleeve to drive the ball head 3073 to rotate and adjust the spray angle of the nozzle to an appropriate position. Then, the threaded sleeve 3072 is rotated so that the opening of the threaded sleeve 3072 is tightly pressed against the outer wall of the ball head 3073, so that the ball head 3073 cannot rotate, thereby fixing the nozzle at an appropriate angle. Then, as the motor 201 drives the protective mechanism 3 to move, the protective mechanism 3 drives the support plate 401 to move, and the support plate 401 slides on the side wall of the rack 403. During this process, the third gear 404 rotates under the action of the rack 403, and the third gear 404 rotates to drive the pulley set 405 to rotate. The pulley set 405 drives the rubber wheel 402 to rotate, so that the rubber wheel 402 drives the wind turbine bearing to rotate. In the process of the protective mechanism 3 driving the wind turbine bearing to move, the wind turbine bearing rotates under the drive of the rotation mechanism 4, so that the spray gun evenly sprays the outer wall of the wind turbine bearing.

[0041] Please refer to Figure 1-8The unloading mechanism 5 includes a rotating arm 501, a hydraulic rod 502, an arc frame 503, a rubber block 504, a bottom plate 505, and a baffle 506. The top of the shell 1 is rotatably connected to two groups of rotating arms 501. The side walls of the two groups of rotating arms 501 are respectively hinged to one end of the two groups of hydraulic rods 502. The other ends of the two groups of hydraulic rods 502 are hinged to the top of the shell 1. The arc frame 503 is fixedly connected between the two groups of rotating arms 501. The side walls of the arc frame 503 are fixedly connected to the rubber block 504. The arc frame 503 is fixedly connected to the bottom plate 505 at the connection with the rotating arm 501. The inner wall of the bottom plate 505 is rotatably connected to the baffle 506 extending to the outside of the bottom plate 505. The baffle 506 is provided with a torsion spring at the connection with the bottom plate 505.

[0042] When the protective mechanism 3 drives the wind turbine bearing to move, the bottom plate 505 goes deep under the wind turbine bearing, so that the wind turbine bearing slides to the top of the bottom plate 505 along the slope of the floor. At this time, the protective pressure plate drives the support rod 304 to slide upward inside the sliding sleeve 302. When the wind turbine bearing contacts the baffle 506, it pushes the baffle 506 to flip and twist the torsion spring. After the wind turbine bearing slides over the baffle 506, the torsion spring pushes the baffle 506 to reset. At this time, the end of the top rod 308 outside the base 301 is blocked by the protrusion 311 and retracts into the base 301. When the top rod 308 retracts into the base 301, it pushes the inclined block 309 and compresses the No. 2 spring 310. At this time, the inclined block 309 cannot block the sleeve, so the No. 1 spring 303 pushes the two sets of sleeves 302 to reset, thereby making the protective mechanism 308 The pressure plate 306 separates from the wind turbine bearing, causing the bearing to fall into the interior of the arc frame 503, and due to the obstruction of the baffle 506, the wind turbine bearing cannot slide out of the arc frame 503, and then the motor 201 rotates in the opposite direction to cause the threaded rod 203 to rotate in the opposite direction, thereby causing the protective mechanism 3 and the rotation mechanism 4 to move in the opposite direction and reset. At this time, the arc frame 503 loses the support of the support plate 401, so that the weight of the wind turbine bearing pushes the arc frame 503 to flip, so that the arc frame 503 drives the rotating arm 501 to flip, and the hydraulic rod 502 is compressed during the flipping of the rotating arm 501, so that the arc frame 503 will not fall to the ground quickly during the flipping process, preventing the wind turbine bearing from falling to the ground and being damaged, pushing the baffle 506 to flip to the inside of the base plate 505, and then using the lifting equipment to move the wind turbine bearing away.

[0043] In use, the wind power bearing is placed between the two sets of protective pressing plates, and then the two sets of sheaths are pushed towards the middle to compress the first spring 303. The two sets of sliding sleeves 302 are closed together, and through the support rods 304, the two sets of rotating shafts 305 are brought closer to each other, so that the rotating shafts 305 push the protective pressing discs 306 closer to each other, so that the protrusions in the middle of the protective pressing discs 306 extend into the inner ring of the bearing, and the outer rings of the protective pressing discs 306 are pressed between the inner and outer rings of the bearing, so as to prevent the sprayed material from entering the bearing interior through the gap between the inner and outer rings to damage the rollers. In the process of closing the two sets of sliding sleeves 302 towards each other, the side walls of the sliding sleeves 302 contact the inclined blocks 309, so that the inclined blocks 309 are pushed and slide. The sliding of the inclined blocks 309 drives the top rods 308 to slide, so that the top rods 308 compress the second springs 310. After the sliding sleeves 302 completely pass the inclined blocks 309, the second springs 310 push the top rods 308 to reset, so that the inclined blocks 309 reset. At this time, the sliding strips are blocked by the inclined blocks 309 and cannot be pushed back by the first springs 303. At this time, the wind power bearing is fixed and protected. At this time, the outer wall of the wind power bearing is attached to the outer wall of the rubber wheel 402. Then the motor 201 rotates to drive the first gear 202 to rotate, the first gear 202 drives the second gear 204 to rotate, the second gear 204 drives the threaded rod 203 to rotate, the threaded rod 203 pushes the sliding block 205 to slide, the sliding block 205 drives the protective mechanism 3 to move, thereby driving the wind power bearing to move, so that the protective pressing plates are pressed between the inner and outer rings of the bearing during spraying, thereby preventing the bearing interior from being sprayed during spraying, avoiding damage to the rollers in the bearing interior due to being sprayed, and enabling the bearing to be automatically pushed to rotate during spraying, thereby enabling the bearing to be more conveniently and uniformly sprayed during spraying.
