[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides two technical solutions:

[0022] Example 1

[0023] Please see Figure 1 In this embodiment of the utility model, a device for cleaning the outer wall of stainless steel pipes with multiple diameters includes a vertical plate 1, a base plate 2 is provided on the lower side of one side of the vertical plate 1, a three-disc claw 3 for fixing steel pipes of different diameters is provided on the upper part of the base plate 2, a lifting component 4 is also provided on the vertical plate 1, and a cleaning component 5 is provided on one side of the lifting component 4.

[0024] Please see Figure 2 In this embodiment of the present invention, the cleaning component 5 includes an annular plate 51 and a support plate 52 disposed on one side of the lifting component 4. The annular plate 51 and the support plate 52 are slidably connected by a connecting part. An external gear 54 is disposed on the outside of the annular plate 51. A drive motor 55 is mounted on the upper part of the support plate 52. The output shaft of the drive motor 55 is connected to a drive gear 56 corresponding to the external gear 54. The drive gear 56 meshes with the external gear 54. A tube body 57 is rotatably disposed at the bottom of the annular plate 51. Spray nozzles 58 are densely distributed on the inner side of the tube body 57. The cleaning component 5 also includes a wiping mechanism 59 for wiping the outer wall of the steel pipe.

[0025] In this scheme: the lower end of the steel pipe is fixed on the three-disc claw 3, and then the lifting component 4 can adjust the position of the cleaning component 5. The drive motor 55 drives the drive gear 56 to rotate. Since the drive gear 56 meshes with the external gear 54 on the annular plate 51, the rotation of the drive gear 56 drives the annular plate 51 to rotate. The drive motor 55 drives the drive gear 56 to rotate. Since the drive gear 56 meshes with the external gear 54 on the annular plate 51, the rotation of the drive gear 56 drives the annular plate 51 to rotate.

[0026] For further details, please refer to Figure 2 In this embodiment of the utility model, the lifting component 4 includes a movable sleeve 41 that is longitudinally slidably sleeved on the outside of the upright plate 1 and a servo motor 42 installed on one side above the upright plate 1. A limit sleeve 43 is provided on the side of the movable sleeve 41 away from the support plate 52. The output shaft of the servo motor 42 is connected to a screw 44. The limit sleeve 43 is screwed to the outside of the screw 44. The servo motor 42 drives the screw 44 to rotate. The screw 44 causes the limit sleeve 43 to drive the movable sleeve 41 to move on the upright plate 1, thereby adjusting the position of the cleaning component 5 and facilitating cleaning operations on different positions on the steel pipe.

[0027] For further details, please refer to [link / reference]. Figure 2 In this embodiment of the utility model, the connecting part includes a T-shaped groove 53 disposed on the outer edge of the annular plate 51, and a T-shaped block adapted to the T-shaped groove 53 is disposed on the side of the support plate 52 away from the movable sleeve 41. The T-shaped block is slidably disposed in the T-shaped groove 53.

[0028] For further details, please refer to Figure 2 In this embodiment of the present invention, a delivery pipe 510 is provided on one side of the pipe body 57, and the cleaning liquid is drawn into the pipe body 57 by an external pump.

[0029] Example 2 adds a steel pipe outer wall wiping device to Example 1, as follows:

[0030] Please see Figures 2-3 In this embodiment of the present invention, the wiping mechanism 59 includes an arc-shaped rod 591 hinged to the inner wall of the annular plate 51 and a servo motor 593 mounted on the upper part of the annular plate 51. One end of the arc-shaped rod 591 is provided with a wiping cleaning ball 592. The interior of the annular plate 51 is a hollow structure. The output shaft of the servo motor 593 is located inside the annular plate 51 and connected to an internal gear 594. An arc-shaped rack 595 is slidably provided on the inner wall of the hollow cavity of the arc-shaped rod 591. The arc-shaped rack 595 meshes with the internal gear 594. One end of the arc-shaped rack 595 is hinged to a connecting rod 596, and the other end of the connecting rod 596 is hinged to one side of the arc-shaped rod 591.

[0031] Please see Figures 2-3In this embodiment of the utility model, the inner wall of the annular plate 51 is provided with a movable groove 597 that communicates with its internal hollow cavity, and one end of the connecting rod 596 passes through the movable groove 597.

[0032] In this scheme: while rinsing, the servo motor 593 drives the internal gear 594 to rotate, and the internal gear 594 drives the arc-shaped rack 595 that meshes with it to move. The arc-shaped rack 595 will cause the connecting rod 596 to drive the arc-shaped rod 591 to rotate, so that the wiping cleaning ball 592 at one end of the arc-shaped rod 591 contacts the steel pipe. Then, the drive motor 55 drives the drive gear 56 to rotate. Since the drive gear 56 meshes with the external gear 54 on the annular plate 51, the rotation of the drive gear 56 drives the annular plate 51 to rotate. In this way, the wiping mechanism 59 will wipe and clean different positions on steel pipes of different diameters.

[0033] Working principle: The lower end of the steel pipe is fixed on the three-disc jaw 3, and then the servo motor 42 drives the screw 44 to rotate. The screw 44 causes the limit sleeve 43 to drive the moving sleeve 41 to move on the vertical plate 1, thereby adjusting the position of the cleaning component 5, which is convenient for cleaning different positions on the steel pipe.

[0034] During cleaning, cleaning fluid is introduced into the delivery pipe 510, enters the pipe body 57, and is sprayed from the nozzle 58 onto the steel pipe to perform a rinsing operation.

[0035] While rinsing, the servo motor 593 drives the internal gear 594 to rotate, which in turn drives the arc-shaped rack 595 meshing with it to move. The arc-shaped rack 595 then causes the connecting rod 596 to rotate the arc-shaped rod 591, so that the wiping cleaning ball 592 at one end of the arc-shaped rod 591 comes into contact with the steel pipe. Then, the drive motor 55 drives the drive gear 56 to rotate. Since the drive gear 56 meshes with the external gear 54 on the annular plate 51, the rotation of the drive gear 56 drives the annular plate 51 to rotate. In this way, the wiping mechanism 59 will wipe and clean different positions on steel pipes of different diameters.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
