The support block 2 has a fixing mechanism 4 inside, which fixes the pipe. The body 1 has a grinding mechanism 5 inside, which smooths the pipe surface. The fixing mechanism 4 includes a motor 41, which is the power source. The motor 41 is externally fixedly connected to the outside of the support block 2. A rotating column 42 is fixedly connected to the drive end of the motor 41, driving the rotating column 42 to rotate. A bevel gear 43 is fixedly connected to the outside of the rotating column 42, causing the bevel gear 43 to rotate. The bevel gear 43 is externally rotatably connected to the inside of the support block 2. A rotating column 44 is fixedly connected to the inside of the bevel gear 43, causing the rotating column 44 to rotate. One end of the 4 is fixedly connected to a turntable 45. The rotation of the second rotating column 44 drives the turntable 45 to rotate. The outside of the turntable 45 is rotatably connected to the outside of the support block 2. The inside of the support block 2 is rotatably connected to a bevel gear 47. The first bevel gear 43 and the second bevel gear 47 are meshed. When the first bevel gear 43 rotates, it drives the second bevel gear 47 to rotate. The inside of the second bevel gear 47 is fixedly connected to a rotating column 48. The rotation of the second bevel gear 47 drives the third rotating column 48 to rotate. The inside of the liquid storage tank 3 has a space. The outside of the third rotating column 48 is rotatably connected to the inside of the liquid storage tank 3. The inside of the third rotating column 48 is fixedly connected to a stirring blade 49. The rotation of the third rotating column 48 drives the stirring blade 49 to rotate, which can achieve the effect of preventing the coating from separating. The outside of the turntable 45 is provided with an expansion component 46. The function of the expansion component 46 is to expand to both sides and contact the inner wall of the pipe to achieve the effect of support and fixation.

[0034] The expansion assembly 46 includes a second motor 461, which serves as the power source. The second motor 461 is externally fixedly connected to the outside of the turntable 45. A worm gear 463 is fixedly connected to the drive end of the second motor 461, driving the worm gear 463 to rotate. Two fixed posts 462 are fixedly connected to the outside of the turntable 45, with a protective shell 464 fixedly connected to one end of each post 462. Rotation of the turntable 45 causes the fixed posts 462 to rotate, which in turn causes the protective shell 464 to rotate. Four fixed rods 466 are fixedly connected inside the protective shell 464. A rotating plate 467 is rotatably connected to the outside of each fixed rod 466. The rotating plate 467 is slidably connected to the inside of the protective shell 464. The fixed rods 466 fix the rotating plate 467 to prevent it from falling off. The internal rotating connection of the protective shell 464... There are two worm gears 465, which are meshed with the worm 463. The rotation of the worm 463 drives the worm gears 465 to rotate. The top of the worm gears 465 is fixedly connected to the inside of the rotating plate 467, and the outside of the worm gears 465 is rotatably connected to the inside of the rotating plate 467. When the worm gears 465 rotate, they drive the rotating plate 467 to rotate. Two sliding plates 469 are slidably connected to the outside of the rotating plate 467. When the rotating plate 467 rotates, it drives the sliding plates 469 to move up and down. A second fixing post 468 is fixedly connected to the inside of the sliding plate 469, and the outside of the rotating plate 467 is rotatably connected to the outside of the second fixing post 468. The second fixing post 468 fixes the rotating plate 467 to prevent it from falling off. A support plate 410 is fixedly connected to the outside of the sliding plate 469. The up and down movement of the sliding plate 469 drives the support plate 410 to move.

[0035] Reference Figure 1 and Figure 4 The grinding mechanism 5 includes a motor 51, which is the power source. The motor 51 is externally fixedly connected to the inside of the body 1. The drive end of the motor 51 is fixedly connected to a drive gear 52, which drives the drive gear 52 to rotate. Multiple toothed plates 53 are slidably connected inside the body 1. The toothed plates 53 are meshed with the drive gear 52. The rotation of the drive gear 52 drives the toothed plates 53 to move. A connecting rod 54 is fixedly connected to one end of the toothed plate 53, and a grinding sleeve 55 is fixedly connected to one end of the connecting rod 54. The toothed plate 53 and the grinding sleeve 55 are connected through the connecting rod 54. Moving the toothed plate 53 drives the connecting rod 54 to move, which in turn drives the grinding sleeve 55 to move. The grinding sleeve 55 contacts the outer wall of the pipe and grinds it. The bottom of the support block 2 is fixedly connected to the top of the body 1, and the top of the liquid storage tank 3 is fixedly connected to the top of the support block 2. The support block 2 supports the liquid storage tank 3, which is used to store the required coating.

[0036] Working principle: When pipe needs to be fixed, the support plate 410 is fitted inside the pipe. Then, motor 461 is started to drive the worm gear 463 to rotate. Since the worm gear 463 and worm wheel 465 are meshed, the worm gear 463 drives the worm wheel 465 to rotate. The rotation of the worm wheel 465 drives the rotating plate 467 to rotate. The rotation of the rotating plate 467 drives the sliding plate 469 to move up and down, which in turn moves the support plate 410 up and down. The support plate 410 moves up and down and fits against the upper and lower ends of the pipe to achieve a fixing effect. Motor 41 is then started to drive the rotating column. Rotating column 42 drives bevel gear 43 to rotate, which in turn drives rotating column 44 to rotate, which in turn drives turntable 45 to rotate. Turntable 45 in turn drives expansion assembly 46 to rotate. Since bevel gear 43 and bevel gear 47 are meshed, when bevel gear 43 rotates, it drives bevel gear 47 to rotate. The rotation of bevel gear 47 drives rotating column 48 to rotate, which in turn drives stirring blade 49 to rotate in storage tank 3, thereby preventing coating delamination.

[0037] Before spraying, start motor 3 51 to drive the drive gear 52 to rotate. Since the drive gear 52 and the tooth plate 53 are meshed, when the drive gear 52 rotates, it pushes the tooth plate 53 to move left and right, pushes the connecting rod 54 to move left and right, and pushes the grinding sleeve 55 to fit against the outer wall of the pipe to be sprayed. Then, rotate the pipe to grind the outer wall of the pipe flat to ensure uniform spraying.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
