[0030] Working principle:

[0031] When in use, the device is connected to a power source, and then multiple sets of arc-shaped fixing plates 6 are inserted into the inner side of the steel pipe;

[0032] The staff can start the electric telescopic rod 17 through the control panel 21, so that the electric telescopic rod 17 pushes the mounting block 11 to move, and the mounting block 11 drives the multiple sets of hinged rods 23 to move together, so that the hinged rods 23 are stressed and push the sliding plate 20 to move, and the sliding plate 20 drives the arc-shaped fixing piece 6 to move together, so that the arc-shaped fixing piece 6 can be closely fitted with the inner wall of the steel pipe, and the steel pipe can be fixed on the outer side of the multiple sets of arc-shaped fixing pieces 6;

[0033] During spraying, the staff can add an appropriate amount of paint liquid into the liquid storage tank 1, and then the staff can start the liquid pump 3 through the control panel 21, and the liquid pump 3 pumps the paint liquid inside the liquid storage tank 1 into the inside of the spray head 10, and sprays the outer wall of the steel pipe through the spray head 10;

[0034] During the spraying process, the staff can start the first motor 18 through the control panel 21, and the first motor 18 drives the U-shaped plate 16 to rotate through the first rotating shaft 19, which can drive the steel pipe to rotate and turn the steel pipe over, so that the paint liquid can be evenly sprayed to different positions of the outer wall of the steel pipe;

[0035] At the same time, the staff can start the second motor 27 through the control panel 21, so that the second motor 27 drives the first rotating disk 13 to rotate at a constant speed through the second rotating shaft 26, and the first rotating disk 13 drives the fixing rod 25 to rotate. Since the fixing rod 25 is installed on the inner ring of the bearing 24, and the connecting rod 12 is installed on the outer ring of the bearing 24, the connecting rod 12 can rotate independently outside the fixing rod 25 through the bearing 24, so that the connecting rod 12 can always face one end of the L-shaped plate 9;

[0036] When the fixing rod 25 rotates to be close to one end of the first sliding assembly 8, the fixing rod 25 drives the connecting rod 12 to move through the bearing 24, so that the connecting rod 12 is subjected to force and pushes the L-shaped plate 9 to move, thereby driving the nozzle 10 to move;

[0037] When the fixing rod 25 rotates to one end away from the first sliding assembly 8, the fixing rod 25 drives the connecting rod 12 to move through the bearing 24, so that the connecting rod 12 is subjected to force and pulls the L-shaped plate 9 to move, thereby driving the nozzle 10 to move;

[0038] Since the second motor 27 drives the first turntable 13 to rotate at a constant speed through the second rotating shaft 26, the connecting rod 12 can repeatedly push and pull the L-shaped plate 9 to move, and the nozzle 10 can be reciprocated to different positions of the steel pipe for spraying. No staff is required to operate, the device has a high degree of automation and is more convenient to use.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
