Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a multi-angle adjustable spraying device for automated painting of steel structures. Background Technology

[0002] Steel structures are structures made primarily of steel. Steel, with its high strength, good toughness, and ease of construction, is used to combine structural steel and steel plates into load-bearing or support systems through welding, bolting, and other methods. They are widely used in construction, machinery manufacturing, shipbuilding, and other fields. Steel structures require painting for two main reasons: first, corrosion and rust prevention. The main material of steel structures is ferroalloy, which is prone to electrochemical corrosion and rusting when exposed to air, water, or humid environments, leading to decreased strength and structural damage. The paint coating isolates the steel from external corrosive media. Second, it protects and extends the lifespan of the steel. Painting forms a protective layer on the steel surface, reducing damage from mechanical impacts and wear. Furthermore, different colored coatings can enhance the appearance, distinguish component functions, or indicate safety information, comprehensively improving the durability and practicality of the steel structure.

[0003] In existing technologies, steel structure spraying devices have at least the following drawbacks:

[0004] First, existing technologies struggle to effectively paint the interior and reinforcing ribs of I-beams. The lack of a horizontally movable and rotatable nozzle structure, coupled with a fixed nozzle position, prevents adaptation to the complex internal structure of the workpiece, resulting in incomplete paint coverage and dead zones. Second, existing technologies require manual operation for workpiece flipping, which is inefficient and cannot be integrated with the painting process, affecting the overall continuity of operations. Therefore, this invention proposes a multi-angle adjustable spraying device for automated steel structure painting to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-angle adjustable spraying device for automated painting of steel structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-angle adjustable spraying device for automated painting of steel structures includes an I-beam, a track platform on one side of the I-beam, and a spraying assembly for painting the I-beam. The spraying assembly is located on the top surface of the I-beam and includes a connecting pipe seat on the top surface of the I-beam. Movable arms are movably sleeved inside both ends of the connecting pipe seat. A fixed pipe is connected through one side of each movable arm. An electric push rod is fixedly sleeved on the inner wall of the fixed pipe. A drive motor is installed at one end of the telescopic shaft of the electric push rod. A support pipe is connected at one end of the drive shaft of the drive motor. A nozzle frame module is fixedly installed at one end of the support pipe. Vertical nozzles are installed on the top and bottom surfaces of the nozzle frame module, and a horizontal nozzle is installed on one side of the nozzle frame module. A moving mechanism for lateral movement of the movable arm is provided inside the movable arm.

[0008] As a further embodiment of this utility model, the moving mechanism includes: a fixed plate, which is fixedly installed inside the moving arm. A threaded hole is provided on one side of the fixed plate, and a lead screw is threadedly connected to the inner circular wall of the threaded hole. A dual-axis motor is fixedly installed on the inner bottom surface of the connecting tube seat, and the drive shaft of the dual-axis motor is fixedly installed with the lead screw.

[0009] As a further embodiment of this utility model, a robotic arm vehicle assembly is provided on the top surface of the track platform. The robotic arm vehicle assembly moves on the track of the track platform via moving wheels. The threaded hole, the electric push rod, and the drive motor are all electrically connected to the controller module of the robotic arm vehicle assembly.

[0010] As a further embodiment of this utility model, a limit post is fixedly installed at one end of the lead screw.

[0011] As a further embodiment of this utility model, the bottom surface of the I-beam is provided with two support platforms for supporting it.

[0012] As a further embodiment of this utility model, a fixed frame is fixedly installed on the bottom surface of the support platform. A double-eared hydraulic cylinder is hinged to one side of the fixed frame. An L-shaped flipping frame is hinged to the telescopic end of the double-eared hydraulic cylinder. A second circular through hole is opened on one side of the L-shaped flipping frame. A fixed column is movably sleeved on the inner circular wall of the second circular through hole. The fixed column is fixedly installed on the support platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This spraying device enables precise multi-sided painting of I-beams. By extending and retracting the moving arm, moving and rotating the nozzle laterally, and rotating the workpiece 90 degrees, it can fully cover the internal top, bottom, sides, and reinforcing ribs, ensuring uniform paint coverage and avoiding incomplete coverage or dead spots. The use of stepper motors and attitude sensors improves the equipment's control precision and facilitates adjustment of nozzle spacing and attitude. Furthermore, by activating the double-ear hydraulic cylinders to pull the L-shaped tilting frame, the I-beams are tilted, eliminating the need for manual operation and enabling continuous painting, making it highly practical.

[0024] Reference Figures 1-5 A multi-angle adjustable spraying device for automated painting of steel structures includes: an I-beam 1, a track platform 2 on one side of the I-beam 1, and a spraying assembly for painting the I-beam 1. The spraying assembly is located on the top surface of the I-beam 1 and includes: a connecting pipe seat 4, which is located on the top surface of the I-beam 1. Movable arms 5 are respectively movably sleeved inside both ends of the connecting pipe seat 4. A fixed pipe 6 is connected through one side of the movable arm 5. An electric push rod 7 is fixedly sleeved on the inner circular wall of the fixed pipe 6. A drive motor 8 is installed at one end of the telescopic shaft of the electric push rod 7. A support pipe 9 is connected at one end of the drive shaft of the drive motor 8. A nozzle frame module 10 is fixedly installed at one end of the support pipe 9. Vertical nozzles 11 are respectively installed on the top and bottom surfaces of the nozzle frame module 10. A horizontal nozzle 12 is installed on one side of the nozzle frame module 10. A moving mechanism for moving the movable arm 5 laterally is provided inside the movable arm 5.

[0025] In this embodiment, the moving mechanism includes: a fixed plate 15, which is fixedly installed inside the moving arm 5. A threaded hole 16 is provided on one side of the fixed plate 15. A lead screw 14 is threadedly connected to the inner circular wall of the threaded hole 16. A dual-axis motor 13 is fixedly installed on the inner bottom surface of the connecting pipe seat 4. The drive shaft of the dual-axis motor 13 is fixedly installed with the lead screw 14. A robotic arm vehicle assembly 3 is provided on the top surface of the track platform 2. The robotic arm vehicle assembly 3 moves on the track of the track platform 2 by moving wheels. The threaded hole 16, the electric push rod 7, and the drive motor 8 are all electrically connected to the controller module of the robotic arm vehicle assembly 3.

[0026] In this embodiment, a limit post 22 is fixedly installed at one end of the lead screw 14. Two support platforms 17 are provided on the bottom surface of the I-beam 1 for supporting it. A fixed frame 20 is fixedly installed on the bottom surface of the support platform 17. A double-eared hydraulic cylinder 19 is hinged to one side of the fixed frame 20. An L-shaped flipping frame 18 is hinged to the telescopic end of the double-eared hydraulic cylinder 19. A second circular through hole is opened on one side of the L-shaped flipping frame 18. A fixed post 21 is movably sleeved on the inner wall of the second circular through hole. The fixed post 21 is fixedly installed with the support platform 17.

[0027] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0028] In the existing technology, the track platform 2 and the robotic arm body assembly 3 are mature technologies, and the integration of paint spraying pipelines and air pressure components is also relatively mature. This device mainly modifies the spray gun module to adapt to the painting shape of the I-beam 1.

[0029] When in use, if the user needs to paint the I-beam 1, the I-beam 1 is placed on the top surface of the support platform 17, inside the L-shaped tilting frame 18, so that the I-beam 1 can be rotated 90 degrees by pulling the L-shaped tilting frame 18 through the double-ear cylinder 19. The telescopic shaft of the double-ear cylinder 19 should be covered with a protective sleeve or other protective device.

[0030] During painting, when the interior of the H-shaped I-beam 1 is being painted, the dual-axis motor 13 drives the lead screw 14 to rotate, converting the rotational motion of the lead screw 14 and the threaded hole 16 into linear motion. This opens the two moving arms 5, and the robotic arm of the robotic arm vehicle assembly 3 is then controlled to position the two moving arms 5 on both sides of the I-beam 1. The two moving arms 5 are then retracted and brought closer to the sides of the I-beam 1, allowing the horizontal spray nozzle 12 and the vertical spray nozzle 11 to enter the interior of the I-beam 1. The vertical spray nozzle 11 is positioned vertically to paint the top and bottom surfaces, while the horizontal spray nozzle 12 paints the sides. This activates the painting components. The painting control technology is already mature and will not be described in detail here. Furthermore, the robotic arm vehicle assembly 3 is activated to move and drive the vertical spray nozzle 11 and the horizontal spray nozzle 12 to paint the three sides of the interior of the I-beam 1, ensuring uniform painting.

[0031] During the painting process, the electric push rod 7 is activated to drive the drive motor 8, support tube 9, vertical nozzle 11, and horizontal nozzle 12 to move back and forth horizontally, which improves the uniformity of the paint spraying. At the same time, the drive motor 8 is activated to drive the support tube 9 to rotate the vertical nozzle 11, so that the horizontal setting can be used to paint the reinforcing ribs inside the I-beam 1, ensuring the uniformity of the paint spraying and avoiding incomplete paint coverage and dead corners.

[0032] After the painting is completed, the double-ear hydraulic cylinder 19 is activated to pull the L-shaped tilting frame 18 to tilt the I-beam 1, causing the I-beam 1 to tilt 90 degrees and turn to the side to paint the other two sides. The vertical spray head 11 and the horizontal spray head 12 are selected for painting according to the needs of the part.

[0033] It should be noted that the electric push rod 7, drive motor 8 and dual-axis motor 13 should be stepper motors to improve torque and facilitate control of the distance between the moving arm 5 and the transverse nozzle 12. An attitude sensor is set on the inner side of the nozzle frame module 10 to detect the attitude of the nozzle frame module 10.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
