[0001] This utility model relates to the field of spraying equipment technology, specifically a spraying device for anti-corrosion treatment of steel structure surfaces in building construction. Background Technology

[0002] Steel structures are structural components made of steel materials. They are characterized by high strength, good overall rigidity, and strong resistance to deformation. They are commonly used in high-rise buildings, large stadiums, and factories.

[0003] Generally, after the steel structure is erected, it needs to be sprayed, that is, coated with an anti-corrosion and anti-rust coating to prevent the steel structure surface from rusting. The existing spraying method is mostly manual operation of paint guns. However, the spraying range of the nozzle is fixed, which is inconvenient to adjust according to the shape characteristics of the steel structure, resulting in uneven spraying and waste of paint. Summary of the Invention

The liquid suction end of the liquid pump is connected to an external paint cylinder through a liquid suction pipe. An auxiliary spraying assembly is provided on the other end of the support rod. The support rod is provided with a first pipe and a second pipe that are connected to the liquid outlet end of the liquid pump. The first pipe and the second pipe are respectively connected to the first spray nozzle and the auxiliary spraying assembly.

[0006] The auxiliary spraying assembly includes a mounting chamber, a sliding plate, and an adjusting screw. The mounting chamber is located at the end of the support rod opposite to the liquid pump. A guide groove is provided on the side wall of the mounting chamber. The two ends of the adjusting screw are rotatably mounted inside the mounting chamber, and the adjusting screw has two sets of threads with opposite directions. The sliding plate has two sets of threads, and its lower end is connected to the two sets of threads with opposite directions. Multiple sets of nozzles are provided on the opposite surface of the sliding plate, and the nozzles are connected to the pipeline via flexible hoses. A knob is also rotatably mounted on one side of the mounting chamber and connected to the adjusting screw, which facilitates the adjustment of the distance between the two sets of sliding plates. It is suitable for rapid spraying of structural components such as square tubes, round tubes, and channel steel of different sizes.

[0007] Preferred technical solution 1: In order to facilitate the adjustment of the spraying distance and increase the operator's operating range, a support component is also included. The support component includes a grip and a telescopic rod slidably mounted on the grip. The telescopic rod is provided with a spring pin. The grip has multiple sets of pin holes evenly distributed along its length direction, corresponding to the spring pin. The top of the telescopic rod is connected to the middle of the support rod, which facilitates the adjustment of the extension length of the telescopic rod according to actual needs and increases the operating range.

[0008] Preferred technical solution 2: In order to make the spraying angle adjustable, enhance applicability, and make the operation more flexible and convenient, an electric telescopic rod is hinged to one side of the telescopic rod. The free end of the electric telescopic rod is hinged to the bottom of the support rod near the liquid pump. The bottom of the support rod is hinged to the top of the telescopic rod. The rotation angle of the support rod can be adjusted by extending and retracting the free end of the electric telescopic rod.

Multiple sets of nozzles 12 are provided on the opposite surface of the sliding plate 9, and the nozzles 12 are connected to the pipeline 7 through a flexible hose 13. A knob 14 is also rotatably located on one side of the installation chamber 8 and is connected to the adjusting screw 10 to facilitate the adjustment of the distance between the two sets of sliding plates 9. It is suitable for rapid spraying of structural components such as square tubes, round tubes, and channel steel of different sizes.

[0026] Example 2

[0027] Based on Embodiment 1, as shown in Figures 1 and 2, in order to facilitate the adjustment of the spraying distance and increase the operator's operating range, a support assembly 15 is also included. The support assembly 15 includes a grip rod 16 and a telescopic rod 17 slidably mounted on the grip rod 16. The telescopic rod 17 is provided with a spring pin 18. The grip rod 16 is provided with multiple sets of pin holes 19 evenly distributed along its length direction, corresponding to the spring pin 18.
