[0024] Specifically, as shown in Figure 1 、 Figure 2 and Figure 3 , the steel pipe to be painted is placed above the sliding plate assembly 9, then the clamping assembly 7 fixed on both sides of the top of the sliding plate assembly 9 is used to clamp and fix one end of the steel pipe, then the rotation of the output end of the first motor 5 can drive the threaded rod 2 to rotate in the inner part of the base 1, the rotation of the threaded rod 2 can drive the sliding block 4 to slide along the installation direction of the threaded rod 2 and the supporting slide rod 3, at the same time, the sliding plate assembly 9 above the base 1 is moved, so that the clamped and fixed steel pipe is driven, so that one end of the steel pipe is sent into the painting mechanism for painting treatment. Since the pushing assembly 6 is movably installed in the inner part of the sliding plate assembly 9, the supporting plate 8 is fixed on the top of the sliding plate assembly 9, and the plurality of auxiliary wheels 801 are movably installed on the top of the supporting plate 8, therefore, when one end of the steel pipe enters the inner part of the painting mechanism and completes the painting, the pushing assembly 6 can be controlled to move towards one end of the steel pipe, and the two clamping assemblies 7 can be controlled to cancel the clamping of the steel pipe, so that the bottom of the steel pipe falls on the top of the supporting plate 8.

Through the device, the steel pipe to be painted can be stably driven, and the clamped and fixed part of the steel pipe can also be painted at the same time during the painting of the steel pipe, so as to improve the working efficiency of the steel pipe painting.

[0026] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the rotating of the output end of the second motor 902 can drive the rotating rod 903 to rotate in the sliding plate body 901, the rotating of the rotating rod 903 can drive the two gears 904 to rotate at the same time, the rotating of the gears 904 can drive the telescopic rods 602 to extend and retract in the sliding plate body 901 due to the tooth engagement between the gears 904 and the toothed strips 604 fixed in the telescopic rods 602, the stability of the telescopic rods 602 during movement can be ensured through the cooperation of the limiting blocks 606 and the limiting groove 905, and the extension and retraction of the two telescopic rods 602 can drive the pushing plate 601 to push one end of the steel pipe; the rubber pad 603 fixed to one side of the pushing plate 601 can protect one end of the steel pipe, so that the one end of the steel pipe is prevented from being abraded.

[0027] In the embodiment, the clamping assembly 7 comprises a fixed plate 701, one side of the fixed plate 701 is fixed with a pneumatic cylinder 703 through bolts, the output end of the pneumatic cylinder 703 slidably penetrates into the fixed plate 701, and the output end of the pneumatic cylinder 703 is fixed with a pipe clamping plate 702 through bolts, the top of the base 1 is provided with a second sliding groove 102, and the top end of the sliding block 4 extends out of the base 1 through the second sliding groove 102, the two sides of the top of the base 1 are provided with a first sliding groove 101, the two sides of the bottom of the sliding plate body 901 are welded with a second slide rod 906, and the two sides of the bottom of the pushing plate 601 are welded with a first slide rod 605, and the bottom ends of the second slide rod 906 and the first slide rod 605 are slidably arranged in the first sliding groove 101.

[0028] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , by controlling the extension of the output end of the air cylinder 703, the pipe clamping plate 702 can be driven to stretch between the two fixed plates 701, so as to adjust the distance between the two pipe clamping plates 702, thereby stably clamping one end of the steel pipe. When the slide plate body 901 and the push plate 601 slide above the base 1 respectively, the second slide rod 906 and the first slide rod 605 will slide inside the first slide groove 101, thereby further ensuring the stability of the slide plate body 901 and the push plate 601 when moving.
