[0026] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Embodiment 1:

[0028] As Figures 1 to 8As shown in the figure, a surface cleaning device for a hollow shaft according to the present utility model includes a cleaning box 1. A motor 2 is fixedly connected to the outer end of the rear side of the cleaning box 1 to fix the motor 2 through the cleaning box 1. A first transmission rod 21 is fixedly connected to the output end of the motor 2, and the first transmission rod 21 is driven to rotate by the motor 2. The outer side of the first transmission rod 21 is meshed with symmetrically arranged front and rear conveying chains 22. The inner end of the right side of the conveying chain 22 is meshed with the same first transmission rod 21. The two ends of the first transmission rod 21 are connected through the conveying chain 22. The left first transmission rod 21 drives the conveying chain 22 to rotate, and the right first transmission rod 21 limits the right side of the conveying chain 22. The outer side of the first transmission rod 21 is rotatably connected to symmetrically arranged front and rear support plates 23. The two sides of the first transmission rod 21 limit the support plates 23, and the two sides of the support plates 23 are fixedly connected through the water inlet pipe 5 and the air inlet pipe 53 at the same time. A cleaning component is arranged at the left end of the inner side of the support plate 23, and a drying component is arranged at the right end of the inner side of the support plate 23. A second transmission rod 31 is rotatably connected to the inner side of the front conveying chain 22. The second transmission rod 31 is limited by the conveying chain 22. A limiting component is arranged at the front end of the second transmission rod 31. A connecting frame 32 is fixedly connected to the rear side of the second transmission rod 31. The connecting frame 32 fixes the cylinder 33. The top end of the cylinder 33 is fixedly connected to a fixing plate 34. The fixing plate 34 is driven to lift by the cylinder 33. The outer side of the fixing plate 34 is rotatably connected to symmetrically arranged front and rear hinge frames 35. The outer side of the hinge frame 35 is fixedly connected to a clamping arm 37. The fixing plate 34 and the clamping arm 37 are connected through the hinge frame 35. The gap of the hinge frame 35 itself is relatively large, so that a certain degree of horizontal movement can be carried out between the inner end of the clamping arm 37 and the fixing plate 34. A rotating shaft 36 is fixedly connected to the outer side of the clamping arm 37 near the hinge frame 35. The clamping arm 37 fixes the rotating shaft 36. The rotating shaft 36 is rotatably connected to the connecting frame 32. The connecting frame 32 limits the rotating shaft 36, thereby limiting the clamping arm 37. A corresponding limiting frame 38 is fixedly connected to the front end of the rear conveying chain 22. The limiting frame 38 is fixed by the conveying chain 22. The rear end of the hollow shaft 4 is clamped and limited by the inner side of the front end of the limiting frame 38. The hollow shaft 4 is clamped and connected to the clamping arm 37. The front end of the hollow shaft 4 is clamped and fixed by the clamping arm 37.

[0029] The limiting component includes a rack 24. The bottom end of the front support plate 23 is fixedly connected to the rack 24, and the rack 24 is fixed by the front support plate 23. The bottom end of the rack 24 is meshed with evenly distributed gears 3. The gears 3 are fixedly connected to the second transmission rod 31. The rack 24 is used to limit the gears 3. Thus, while the conveyor chain 22 rotates, it drives the second transmission rod 31 and the cylinder 33 to move left and right. And by using the rack 24 to limit the gears 3, the gears 3 rotate around their own axes while revolving, thereby driving the hollow shaft 4 to rotate synchronously around its own axis.

[0030] The cleaning component includes a water inlet pipe 5. The left inner end of the front support plate 23 is fixedly connected to the water inlet pipe 5, and the water inlet pipe 5 is fixed by the support plate 23. A first shunt pipe 51 is fixedly connected to the rear side of the water inlet pipe 5. Evenly distributed first spray nozzles 52 are fixedly connected to the bottom end of the first shunt pipe 51. The first shunt pipe 51 is used to shunt the cleaning water transported in by the water inlet pipe 5 into the first spray nozzles 52. Thus, the cleaning water is atomized by the first spray nozzles 52 and sprayed out at high speed to clean the outer surface of the hollow shaft 4. A water outlet 56 is fixedly connected to the rear end of the first shunt pipe 51. The cleaning water is sprayed out at high speed through the water outlet 56 and enters the inner side of the hollow shaft 4. Thus, the inner surface of the hollow shaft 4 is cleaned by the water flow.

[0031] The air-drying component includes an air inlet pipe 53. The bottom side of the rear end of the air inlet pipe 53 is fixedly connected to a second shunt pipe 54. Evenly distributed second spray nozzles 55 are fixedly connected to the bottom end of the second shunt pipe 54. An air outlet 57 is fixedly connected to the rear end of the second shunt pipe 54. The air transported in by the air inlet pipe 53 and the second shunt pipe 54 is sprayed out at high speed through the second spray nozzles 55 to air-dry the outer surface of the hollow shaft 4. At the same time, the air is sprayed out at high speed through the air outlet 57 to air-dry the inner surface of the hollow shaft 4.

[0032] The limiting frame 38 is slidably connected to the water outlet 56 and the air outlet 57.

[0033] Evenly distributed support legs 11 are fixedly connected to the bottom end of the cleaning tank 1. The cleaning tank 1 is supported by the support legs 11. A filter plate 12 is fixedly connected to the inner bottom end of the cleaning tank 1. The cleaning water sprayed out of the cleaning tank 1 is filtered by the filter plate 12.

[0034] Working principle: When the hollow shaft surface cleaning device is running, first, the rear end of the hollow shaft 4 is clamped into the limit frame 38, and then the front end of the hollow shaft 4 is placed inside the clamping arm 37. Then, the cylinder 33 drives the fixed plate 34 to move downward, so as to pull the inner end of the clamping arm 37 downward through the fixed plate 34, making the clamping arm 37 rotate around the rotating shaft 36. The top end of the clamping arm 37 moves inward to clamp and fix the front end of the hollow shaft 4. Then, the motor 2 drives the first transmission rod 21 to rotate, and at the same time, the first transmission rod 21 drives the conveying chain 22 to rotate. Then, the motor 2 drives the second transmission rod 31 to move. During the movement, the rack 24 on the bottom side of the front support plate 23 limits the gear 3, so as to drive the gear 3 to rotate. The gear 3 drives the connecting frame 32 to rotate synchronously through the second transmission rod 31. Then, the connecting frame 32 drives the rear structure and the hollow shaft 4 to rotate. Then, the first shunt pipe 51 shunts the cleaning water conveyed by the water inlet pipe 5 into the first spray head 52 and the water outlet 56. The cleaning water is atomized and sprayed out at high speed through the first spray head 52 to clean the outer surface of the hollow shaft 4. At the same time, the cleaning water is sprayed into the inner side of the hollow shaft 4 at high speed through the water outlet 56 to clean the inner surface of the hollow shaft 4. Then, the second shunt pipe 54 shunts the air conveyed by the air inlet pipe 53 into the second spray head 55 and the air outlet 57. The second spray head 55 sprays the air out at high speed to dry the outer surface of the hollow shaft 4. Then, the air is sprayed into the hollow shaft 4 through the air outlet 57 to dry the inner surface of the hollow shaft 4.
