The second electromagnetic suction cup 72 can also adsorb the iron block 51 when powered on. The first electromagnetic suction cup 62 and the second electromagnetic suction cup 72 are respectively located on both sides of the iron block 51.

[0069] Two support plates 8 are also provided on the cleaning box 1. The two support plates 8 are L-shaped and symmetrically arranged. A support column 81 is fixedly arranged on each support plate 8. The two support columns 81 are arranged in parallel and both support columns 81 penetrate the support frame 5. Specifically, two through holes are provided on the support frame 5. The two support columns 81 pass through the two through holes respectively, and the aperture of the through hole is larger than the outer diameter of the support column 81. A spring 82 is respectively sleeved on the outside of each support column 81, and the spring 82 is arranged between the support frame 5 and the support plate 8.

[0070] The elastic stretching component 9 includes a fixed head 91, which is fixedly arranged at one end of the flexible belt 2 away from the cleaning box 1; the elastic stretching component 9 also includes a spring pull box 92, which has a spiral spring built in it; a pull rope 94 is connected between the fixed head 91 and the spring pull box 92, that is, the two ends of the pull rope 94 are respectively connected to the fixed head 91 and the spring pull box 92; a supporting base plate 96 is arranged on the bottom inner wall of the cleaning box 1, and a fixing column 95 is arranged on the supporting base plate 96; a guide wheel 93 is arranged on the top of the fixing column 95, and the pull rope 94 passes around the guide wheel 93, and the pull rope 94 is inserted into the guide wheel 93; that is, the pull rope 94 is stretched by the spring pull box 92, so as to facilitate straightening the flexible belt 2.

[0071] See also Figure 1-Figure 6In this embodiment, when the outer ring of the slewing bearing is cleaned, first, the outer ring of the slewing bearing is placed on the arc-shaped support bar 43, and the limiting column 42 passes through one of the mounting holes on the outer ring of the slewing bearing; by adding a proper amount of cleaning liquid composed of water and cleaning agent to the cleaning box 1, and energizing the first electromagnetic suction cup 62 for one second (the second electromagnetic suction cup 72 is not energized at this time), the first electromagnetic suction cup 62 absorbs the iron block 51, thereby driving the support slide bar 3, the support frame 5 and the iron block 51 to move until the iron block 51 contacts the first electromagnetic suction cup 62. During this process, the support slide bar 3 drives the fixing component 4 to move, and the spring 82 is compressed, and the fixing component 4 drives the outer ring of the slewing bearing to move, and the outer ring of the slewing bearing hits the corresponding strip-shaped flexible brush body 21. Since two limiting guide columns 13 are provided, and the plane where the axes of the two limiting guide columns 13 are located is close to one side edge of the outer ring of the slewing bearing, it is convenient to squeeze the corresponding strip-shaped flexible brush body 21 to form an arc-shaped covering on the outer ring of the slewing bearing, that is, Figure 6 In the state shown, half of the gear teeth of the outer ring of the slewing bearing are covered by the strip-shaped flexible brush body 21; thereafter, the first electromagnetic suction cup 62 is powered off, and the outer ring of the slewing bearing and the flexible belt 2 are easily reset under the action of the spring 82 and the spring pull box 92. During the resetting process of the outer ring of the slewing bearing, the outer ring of the slewing bearing impacts the cleaning liquid, and under the action of the spring 82, it is easy to cause a certain back and forth vibration effect of the outer ring of the slewing bearing (which helps to improve the cleaning effect of the outer ring of the slewing bearing).

[0072] After the first electromagnetic suction cup 62 is powered off for 1-2 seconds, the second electromagnetic suction cup 72 is powered on for one second. During this process, the second electromagnetic suction cup 72 absorbs the iron block 51 to realize the movement of the support slide bar 3, the fixing component 4 and the outer ring of the slewing bearing, thereby driving the outer ring of the slewing bearing to impact another strip-shaped flexible brush body 21. Similarly, the other half of the outer ring of the slewing bearing is covered by the corresponding strip-shaped flexible brush body 21; then the second electromagnetic suction cup 72 is powered off for 1-2 seconds, and the first electromagnetic suction cup 62 is powered on again for one second and then powered off for 1-2 seconds. Repeat the above operation to realize the reciprocating motion of the outer ring of the slewing bearing. During the reciprocating motion, the outer ring of the slewing bearing cyclically impacts the two strip-shaped flexible brush bodies 21, and the two strip-shaped flexible brush bodies 21 cyclically impact and cover the gear part of the outer ring of the slewing bearing, so that the strip-shaped flexible brush bodies 21 can scrape off impurities on the gear part of the outer ring of the slewing bearing; at the same time, the outer ring of the slewing bearing also impacts the cleaning liquid during the reciprocating motion, so as to further improve the cleaning effect of the outer ring of the slewing bearing; after the outer ring of the slewing bearing reciprocates back and forth for a suitable time, the first electromagnetic suction cup 62 and the second electromagnetic suction cup 72 are both powered off, and after the outer ring of the slewing bearing stops moving, the cleaned outer ring of the slewing bearing can be taken out.

[0073] In the process of the outer ring of the slewing bearing impacting the strip flexible brush body 21 and resetting, the flexible belt 2 can be disturbed, and impurities attached to the strip flexible brush body 21 can be shaken off into the cleaning liquid, which helps to improve the cleaning effect of the strip flexible brush body 21 on the outer ring gear part of the slewing bearing.

[0074] Embodiment 2

[0075] See also Figure 1-Figure 9 This embodiment is based on the first embodiment, and a hemispherical slider 911 is provided on the top and bottom of each fixed head 91, and a top plate 97 is provided on the top of the cleaning box 1, the top plate 97 corresponds to the supporting bottom plate 96, and the top plate 97 is arranged parallel to the supporting bottom plate 96; the hemispherical slider 911 on the top of the fixed head 91 is in contact with the top plate 97, and the hemispherical slider 911 at the bottom of the fixed head 91 is in contact with the supporting bottom plate 96; when the outer ring of the slewing bearing impacts the strip-shaped flexible brush body 21 and causes the flexible belt 2 to move, the hemispherical slider 911 on the top of the fixed head 91 moves along the bottom surface of the top plate 97, and the hemispherical slider 911 at the bottom of the fixed head 91 moves along the top surface of the supporting bottom plate 96, which helps to ensure that the fixed head 91 moves stably between the top plate 97 and the supporting bottom plate 96, thereby ensuring that the flexible belt 2 and the strip-shaped flexible brush body 21 will not twist.

[0076] Embodiment 3

[0077] See also Figure 1-Figure 10 , this embodiment is based on the second embodiment, and two guide rollers 98 are respectively arranged on both sides of each pull rope 94, and the guide rollers 98 are fixedly arranged on the supporting bottom plate 96; the guide rollers 98 on both sides of each pull rope 94 are in contact with the pull rope 94, and the guide rollers 98 are used to limit the pull rope 94; the two spring pull boxes 92 are arranged outside the cleaning box 1, so the two pull ropes 94 penetrate the cleaning box 1, and the guide rollers 98 are close to the position where the pull ropes 94 penetrate the cleaning box 1. Through the limiting effect of the guide rollers 98 on the pull ropes 94, the pull ropes 94 between the guide wheel 93 and the spring pull box 92 are kept in a straight state; in addition, the heights of the two pull ropes 94 are consistent, and the position of the pull ropes 94 is higher than the position of the flexible belt 2. When the outer ring of the slewing bearing is placed on the fixed component 4, the outer ring of the slewing bearing corresponds to the middle position of the flexible belt 2; when adding cleaning liquid to the cleaning box 1, the liquid level of the cleaning liquid can be slightly higher than the outer ring of the slewing bearing, so as to avoid the cleaning liquid from being discharged from the position where the cleaning box 1 is penetrated by the pull rope 94.
