[0002] After processing, the surface of the I-shaped steel beam needs to be painted to improve the overall anti-rust effect of the steel beam. The existing I-shaped steel beam painting work generally needs to be completed manually, and manual painting requires two spraying operations.

[0003] Of course, there are also automated painting equipment available, such as the one disclosed in authorization announcement number CN 115870140 B, which has an adjustable painting range. The height between the painting position and the steel beam body can be adjusted so that steel beams of different specifications are painted at the same height during the painting process, thereby ensuring a uniform painting effect on the outer wall of the steel beam body.

[0004] However, due to the relatively complex surface structure of the I-beam, the above-mentioned public document only provides a paint nozzle facing one side of the steel beam, which may result in the need to paint a single I-beam multiple times, and it is impossible to paint the concave surface of the I-beam. Therefore, the painting efficiency and painting effect are not ideal. Utility Model Content

The horizontal beam 2 is fixed on the vertical pole 1, and the two ends of the horizontal beam 2 can be detachably fixed to the top ends of the two vertical poles 1 by bolts; the length of the adjusting beam 3 is shorter than the horizontal beam 2, and the lower end surface of the horizontal beam 2 is provided with an adjusting slide groove 201, and the length direction of the adjusting slide groove 201 is consistent with the length direction of the horizontal beam 2; the upper end surface of the adjusting beam 3 is fixed with an adjusting slider 31, and the adjusting slider 31 is slidably provided in the adjusting slide groove 201; two or more adjusting sliders 31 are provided; in this way, the adjusting beam 3 can slide relative to the vertical pole 1 and the horizontal beam 2, specifically, the adjusting beam 3 slides along the length direction of the horizontal beam 2 within the range between the two vertical poles 1.

[0026] When the adjusting screw rod 33 is rotated, the nut seat 32 will drive the adjusting beam 3 to slide due to the cooperation with the adjusting screw rod 33, and the adjusting slider 31 fixed at the top end of the adjusting beam 3 slides in the adjusting slot 201, so that the adjusting beam 3 has only axial sliding but no axial rotation.

[0027] A telescopic rod 5 is fixed to the middle of the lower end surface of the adjusting beam 3, and a pair of paint spraying rods 4 are slidably provided on both sides of the telescopic rod 5 on the lower end surface of the adjusting beam 3, and the two paint spraying rods 4 can approach or move away from each other along the length direction of the adjusting beam 3; a paint spraying slider 41 is slidably provided on the paint spraying rod 4, and the paint spraying slider 41 can approach or move away from the adjusting beam 3 along the length direction of the vertical pole 1, and the paint spraying slider 41 extends from the surface of the paint spraying rod 4 along the length direction of the adjusting beam 3 toward the direction of the telescopic rod 5; the ends of the telescopic rod 5 and the paint spraying slider 41 are provided with nozzles for spraying paint, and the nozzle on the telescopic rod 5 is facing away from the adjusting beam 3, and the paint spraying slider 41 is provided with three nozzles, one of which is facing away from the paint spraying slider 41, and the other two nozzles are arranged opposite to each other.

[0028] like Figure 3As shown, when the I-shaped steel beam 6 passes between the vertical pole 1 and the adjusting beam 3, the telescopic rod 5 on the adjusting beam 3 can be placed directly above the steel beam 6 by controlling the rotation of the adjusting screw 33, and then the telescopic rod 5 is adjusted to be at a suitable distance from the steel beam 6 for spraying paint; then the paint slider 41 on the paint spray rod 4 is controlled to be adjusted along the length direction of the paint spray rod 4 to the middle position on both sides of the steel beam 6; then the two paint spray rods 4 are brought close to each other, so that the three nozzles on the paint slider 41 are at a suitable distance from the three surfaces of the concave surface of the steel beam 6 for spraying paint.

[0029] In this way, because there are paint spray nozzles surrounding the three sides of the I-shaped steel beam, and the distances between the nozzles facing the three sides of the steel beam and the three sides of the steel beam can be adjusted, after the adjustment is completed, the I-shaped steel beam will be efficiently painted when passing between the vertical pole and the adjustment beam, and the painting effect is good. Two sprayings can complete the paint coverage of all sides of the I-shaped steel beam.

[0030] In one embodiment of the present application, preferably, a linear rotating bushing 34 is fixedly provided inside the adjusting beam 3, and the adjusting screw 33 is slidably and rotatably passed through the linear rotating bushing 34; of course, the linear rotating bushing 34 can also be replaced by a solution of a linear bearing with a traditional bearing outside; accordingly, the middle and both ends of the adjusting screw 33 are not provided with threads, the middle part is not provided with threads for passing the linear rotating bushing 34, and the two ends are not provided with threads for setting bearings, and the bearings are set on the vertical rod 1; therefore, two sections of threads are provided on the adjusting screw 33, and the thread direction and pitch of the two sections of threads are the same.
