A limit plate 14 is provided at one end of the spring 13. A clamping plate 15 is welded thereon at the central position of the outer wall on the side away from the spring 13 on the limit plate 14. A support plate 16 is fixedly connected to the outer wall of the side of the base 1 away from the upper and lower ramps 2 by bolts. The top of the support plate 16 is fixedly connected to the spray box 17 and the spray pump 18 by bolts. The spray box 17 is located on one side of the spray pump 18. The bottom of the support plate 16 is fixedly connected to the spray nozzle 19 by bolts. A connecting pipe 20 is provided between the spray nozzle 19 and the spray box 17 and the spray pump 18. The top of the base 1 is embedded with a ball screw 21 for rotation connection. A groove is provided on the top of the base 1 near the outside of the ball screw 21. There are two ball screws 21 in total, and the two ball screws 21 are symmetrically embedded in the top of the base 1. The nut seat on the ball screw 21 is fixedly connected to the baffle 22 by a nut.

[0023] It should be noted that, since the existing spraying device is not convenient for positioning and clamping the embedded steel pipe when spraying the embedded steel pipe, the surface of the steel pipe is easily blocked by the clamp, resulting in uneven spraying, which leads to poor anti-rust effect of the steel pipe. In this embodiment, the embedded steel pipe is positioned by the clamping plate 15 and then the plug 11 is inserted into the inner side of the embedded steel pipe to achieve clamping. The entire outer surface of the embedded steel pipe is exposed, and it will not be blocked when spraying the rust inhibitor, causing uneven spraying. The embedded steel pipe can be sprayed in all directions by lifting it off the ground and rotating it, thereby improving the spraying efficiency. The cooperation between the base 1 and the upper and lower inclined platforms 2 facilitates the loading and unloading of the embedded steel pipe. There is no need for manual or mechanical lifting of the embedded steel pipe, and the loading and unloading operations of the embedded steel pipe are simpler and more convenient.

[0024] Specifically, in this embodiment, this scheme mainly includes an upper and lower inclined platform 2, a movable platform 5 and a fixed frame 6. When the embedded steel pipe is sprayed with anti-rust paint, the distance between the baffle 22 and the center of the column 11 is adjusted according to the inner radius of the embedded steel pipe. During operation, the ball screw 21 is rotated, and the baffle 22 on the ball screw 21 moves on the base 1, so that the position of the baffle 22 can be adjusted. The embedded steel pipe is pushed to the base 1 by the upper and lower inclined platforms 2, and the outer wall of the embedded steel pipe is in contact with the outer wall of the baffle 22. The baffle 22 limits the embedded steel pipe. At this time, the second electric push rod 7 drives the lifting platform 8 to move downward through the output end on one side thereof. The lifting platform 8 rises and falls on the inner side of the fixed frame 6, and the center of the column 11 is lifted and lowered to a horizontal coaxial line with the center of the embedded steel pipe. The two first electric push rods 4 work synchronously. The first electric push rod 4 drives the two first electric push rods 4 through the output end on one side thereof. The two moving platforms 5 move closer, and the two fixed frames 6 on the moving platform 5 move synchronously, and the column 11 is inserted into the embedded steel pipe. When the column 11 is in the insertion process, the card plate 15 contacts the inner wall of the embedded steel pipe, and the card plate 15 is pressed to move toward the inner column 12. The spring 13 is compressed, and the outer wall of the card plate 15 is in close contact with the inner wall of the embedded steel pipe through the rebound force of the spring 13 to achieve clamping of the embedded steel pipe. The second electric push rod 7 drives the lifting platform 8 to move upward through the output end on one side thereof, and the embedded steel pipe is lifted off the ground. During the spraying operation, the spray pump 18 draws the anti-rust spray liquid in the spray box 17 into the spray nozzle 19 through the connecting pipe 20, and the spray nozzle 19 sprays the anti-rust spray liquid onto the outer wall of the embedded steel pipe. The rotating cylinder 9 drives the turntable 10 to rotate 360 degrees through the output end on one side thereof, and the anti-rust spray liquid is sprayed on the outer wall of the embedded steel pipe in all directions.

[0025] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the movable platform 5 and the cavity 3 are slidably connected, and the lifting platform 8 and the fixed frame 6 are slidably connected.

[0026] In this embodiment, the sliding connection ensures the stability of the movement of the movable platform 5 in the cavity 3 and the stability of the movement of the lifting platform 8 in the fixed frame 6.

[0027] In a further preferred embodiment of the present invention, Figure 1 、 Figure 3 and Figure 4 As shown, an inclined surface is provided on one side outer wall of the clamping plate 15 .

[0028] In this embodiment, the insertion of the column 11 into the embedded steel pipe can be facilitated by the guidance of the inclined surface.

[0029] In a further preferred embodiment of the present invention, Figure 4 As shown, there are six springs 13 in total, and the six springs 13 are symmetrically arranged in groups of three on the outer side wall of the inner column 12.

[0030] In this embodiment, two clamping plates 15 can be provided on one insertion column 11, thereby effectively clamping one end of the embedded steel pipe.
