[0027] Please see Figures 1-5 A PE anti-corrosion steel pipe spraying device includes an operating table 1. Two adjusting seats 2 are movably mounted on the operating table 1. Each adjusting seat 2 is rotatably mounted on a rotating seat 3 via a bearing. One side of the rotating seat 3 is recessed inward to form four moving chambers 4. A first screw 5 is rotatably mounted in each moving chamber 4. A moving seat 6 is threadedly connected to the first screw 5. One end of the moving seat 6 passes through the moving chamber 4 and is fixedly mounted on a fixing plate 7. A drive chamber 8 is provided inside the rotating seat 3. A first motor 9 is fixedly mounted on one side of the rotating seat 3. The drive end of the first motor 9 extends into the drive chamber 8 and is fixedly mounted on a drive bevel gear 10. One end of each first screw 5 extends into the drive chamber 8 and is fixedly mounted on a driven bevel gear 11.

[0028] In this embodiment, when it is necessary to fix the steel pipe, the position of the adjusting seat 2 is adjusted so that the adjusting seat 2 drives the rotating seat 3 to move. The rotating seat 3 drives multiple fixing rods to be inserted into the steel pipe. The first motor 9 is started, and the first motor 9 drives the driving bevel gear 10 to rotate. Since the driving bevel gear 10 is meshed with the driven bevel gear 11, the driven bevel gear 11 rotates. The driven bevel gear 11 drives the first screw 5 to rotate, so that the moving seat 6 moves. The moving seat 6 drives the fixing plate 7 to move, so that the four fixing plates 7 move at the same time, thereby fixing the steel pipe from the inside.

[0029] Please see Figures 1-5 As one embodiment for adjusting the height of nozzle 14: a bracket 12 is fixedly mounted on the operating table 1, and a spraying base 13 is slidably connected to the bracket 12 via a track structure. An adjustment component is provided on one side of the spraying base 13, and the nozzle 14 is movably connected to the spraying base 13 via the adjustment component. A second screw 15 is rotatably mounted on the bracket 12, and the second screw 15 is threadedly connected to the spraying base 13. One end of the second screw 15 passes through the bracket 12 and is fixedly connected to a second electric motor fixedly mounted on the bracket 12. The adjusting assembly includes a limiting shell 17 fixedly connected to the spray base 13. A third motor 18 is fixedly provided at the upper end of the limiting shell 17. The driving end of the third motor 18 extends into the limiting shell 17 and is fixedly connected to a third screw 19. A lifting seat 20 is threadedly connected to the third screw 19. The lower end of the lifting seat 20 passes through the limiting shell 17 and is fixedly connected to the nozzle 14. Limiting blocks 21 are provided on both sides of the lifting seat 20. Limiting grooves 22 that cooperate with the limiting blocks 21 are provided on both sides of the limiting shell 17.

[0030] Specifically, the third motor 18 is started, which drives the third screw 19 to rotate. Since the third screw 19 is threadedly connected to the lifting seat 20, the lifting seat 20 moves downward and drives the limiting block 21 to move along the limiting groove 22 to limit the position of the lifting seat 20. At the same time, the lifting seat 20 drives the nozzle 14 to move downward, thereby adjusting the height of the nozzle 14 according to the diameter of the steel pipe. Nozzle 14 is fixedly connected to a hose, which is connected to a pump body. The pump body is connected to a storage tank for storing anti-corrosion coating through a pipe. When the pump body is started, the anti-corrosion coating can be delivered to the nozzle 14 and then sprayed out. Since the connection structure (not shown in the figure) and working principle of the nozzle 14 for spraying anti-corrosion coating are existing technologies, they will not be described in detail here. At the same time as the anti-corrosion coating is sprayed out, the second motor 16 is started. The second motor 16 drives the second screw 15 to rotate. Since the second screw 15 is threadedly connected to the spraying seat 13, the spraying seat 13 moves along the sliding connection with the bracket 12. The spraying seat 13 drives the nozzle 14 to move through the adjustment component, thereby spraying the anti-corrosion coating on the outside of the steel pipe.

[0031] Please seeFigures 1-5 As one embodiment of rotating the steel pipe: one end of the rotating seat 3 passes through the adjusting seat 2 and is fixedly connected to a toothed ring 23. The toothed ring 23 is meshed with a drive gear 24. The drive gear 24 is fixedly connected to a fourth motor 25 fixedly mounted on the adjusting seat 2. Two support seats 26 are symmetrically arranged at the lower end of the operating table 1. A bidirectional lead screw 27 is rotatably arranged between the two support seats 26. One end of the bidirectional lead screw 27 passes through the support seat 26 and is fixedly connected to a fifth motor 28 fixedly mounted on one side of the support seat 26. The bidirectional lead screw 27 is threadedly connected to two adjusting frames 29. The adjusting frames 29 are movably sleeved on the outside of the operating table 1. The upper end of the adjusting frame 29 is fixedly connected to the adjusting seat 2.

[0032] Specifically, when it is necessary to adjust the distance between the two rotating seats 3 according to the length of the steel pipe, the fifth motor 28 is started. The fifth motor 28 drives the bidirectional lead screw 27 to rotate. Since the bidirectional lead screw 27 has two threaded areas in opposite directions, the two adjusting frames 29 move in adjacent directions. The adjusting frames 29 drive the adjusting seat 2 to move, the adjusting seat 2 drives the rotating seat 3 to move, and the rotating seat 3 drives the fixing plate 7 to move, thereby inserting the fixing plate 7 into the steel pipe. After the steel pipe is fixed, the fourth motor 25 is started. The fourth motor 25 drives the drive gear 24 to rotate, the drive gear 24 drives the gear ring 23 to rotate, and the gear ring 23 drives the rotating seat 3 to rotate around the rotating connection with the adjusting seat 2. The rotating seat 3 drives the fixed steel pipe to rotate.

[0033] In summary, when using the overall equipment:

[0034] When it is necessary to adjust the distance between the two rotating seats 3 according to the length of the steel pipe, the fifth motor 28 is started. The fifth motor 28 drives the bidirectional lead screw 27 to rotate. Since the bidirectional lead screw 27 has two threaded areas in opposite directions, the two adjusting frames 29 move in adjacent directions. The adjusting frames 29 drive the adjusting seat 2 to move, the adjusting seat 2 drives the rotating seat 3 to move, and the rotating seat 3 drives the fixing plate 7 to move, thereby inserting the fixing plate 7 into the steel pipe.

[0035] When it is necessary to fix the steel pipe, the first motor 9 is started. The first motor 9 drives the drive bevel gear 10 to rotate. Since the drive bevel gear 10 is meshed with the driven bevel gear 11, the driven bevel gear 11 rotates. The driven bevel gear 11 drives the first screw 5 to rotate, which causes the moving seat 6 to move. The moving seat 6 drives the fixing plate 7 to move, so that the four fixing plates 7 move at the same time, thereby fixing the steel pipe from the inside.

[0036] When it is necessary to adjust the height of nozzle 14, the third motor 18 is started. The third motor 18 drives the third screw 19 to rotate. Since the third screw 19 is threadedly connected to the lifting seat 20, the lifting seat 20 moves downward and drives the limiting block 21 to move along the limiting groove 22 to limit the position of the lifting seat 20. At the same time, the lifting seat 20 drives the nozzle 14 to move downward, thereby adjusting the height of nozzle 14 according to the diameter of the steel pipe. Nozzle 14 is fixedly connected to a hose, which is connected to a pump body. The pump body is connected to a storage tank for storing anti-corrosion coating through a pipe. When the pump body is started, the anti-corrosion coating is delivered to nozzle 14 and then sprayed out. Since the connection structure (not shown in the figure) and working principle of nozzle 14 for spraying anti-corrosion coating are existing technologies, they will not be described in detail here. At the same time as spraying anti-corrosion coating, second motor 16 is started. Second motor 16 drives second screw 15 to rotate. Since second screw 15 is threadedly connected to spray base 13, spray base 13 moves along the sliding connection with bracket 12. Spray base 13 drives nozzle 14 to move through adjustment component. Fourth motor 25 is started. Fourth motor 25 drives drive gear 24 to rotate. Drive gear 24 drives gear ring 23 to rotate. Gear ring 23 drives rotating seat 3 to rotate around the rotating connection with adjustment seat 2. Rotating seat 3 drives fixed steel pipe to rotate, thereby spraying anti-corrosion coating on the outside of steel pipe.

[0037] A controller is provided on one side of the control panel 1. All electrical equipment in the entire device is controlled by the controller. Since the equipment matched with the controller is common equipment, its control principle and circuit connection are existing, well-known and mature technologies. Therefore, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
