[0003] Traditional painting operations for large steel structure components mainly rely on manual labor. However, manual painting is inefficient, and given the large surface area of ​​these components, it requires significant time and manpower. Furthermore, during manual painting, the volatile organic compounds (VOCs) and other harmful substances in the paint can seriously endanger workers' health. Long-term exposure to such an environment can lead to various occupational diseases, including respiratory illnesses and skin diseases. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a spraying device for large steel structure components, including a base plate 1. Multiple sets of pads 101 for supporting the steel components are provided on the upper surface of the base plate 1. A U-shaped frame 102 is mounted on the upper surface of the base plate 1 via a traveling mechanism 2. A hydraulic cylinder 103 is mounted on the upper surface of the U-shaped frame 102, and a cover 104 is mounted on the end of the telescopic end of the hydraulic cylinder 103. A liquid storage tank 105 is mounted on the outer surface of the cover 104 via a translation mechanism 3. A spraying mechanism 4 communicating with the liquid storage tank 105 is provided inside the cover 104.

[0021] In use, the steel component to be sprayed is first placed on the two corresponding pads 101, at which point the bottom of the steel component is suspended. Then, the cover 104 is moved above the steel component by the traveling mechanism 2, and the cover 104 is lowered by the hydraulic cylinder 103 so that its bottom is attached to the upper surface of the base plate 1 and covered the outside of the steel component. Subsequently, the outer surface of the steel component can be sprayed with the cooperation of the translation mechanism 3 and the spraying mechanism 4, thus achieving the purpose of automatic spraying. This avoids the serious harm to the health of workers caused by manual spraying, and has good safety and high efficiency. In addition, during the spraying process, the paint floating in the air can be confined within the cover 104, reducing the pollution to the surrounding ring and further ensuring the safety of the working environment.

[0022] Furthermore, the walking mechanism 2, the translation mechanism 3, and the spraying mechanism 4 are all controlled and adjusted by an external controller (not shown), which enables the automatic spraying of the next steel component after the spraying of one steel component is completed, reducing manual intervention and improving spraying efficiency and quality.

[0023] Preferably, the walking mechanism 2 includes two parallel base plates 201 mounted on the upper surface of the base plate 1, with the two base plates 201 respectively disposed on both sides of the pad block 101. A first slide block 202 is slidably mounted on the upper surface of the base plate 201, and a U-shaped frame 102 is mounted on the first slide block 202. A first servo motor 203 is mounted on the upper surface of the first slide block 202, and the end of the output shaft of the first servo motor 203 extends through to the lower side of the first slide block 202 and is mounted with a drive gear 204. A rack 205 is mounted on the upper surface of the base plate 201, and the drive gear 204 meshes with the rack 205.

[0024] When it is necessary to drive the U-shaped frame 102 to move, the first servo motor 203 can be started. The first servo motor 203 drives the drive gear 204 to rotate. Since the drive gear 204 meshes with the rack 205, it can drive the first slide block 202 to move on the surface of the substrate 201 and achieve the purpose of driving the U-shaped frame 102 to move.

[0025] It is worth noting that the synchronous driving of the two first servo motors 203 to drive the drive gear 204 to rotate can be achieved by using a common power supply and a hardware closed loop for feedback from the driver and encoder. This is a common existing technology and will not be elaborated on here.

[0026] Furthermore, the U-shaped frame 102 is moved by the walking mechanism 2, so that there are no obstructions on the upper side of the base plate 1, which will not affect the hoisting and handling of steel components.

[0027] Preferably, the translation mechanism 3 includes a second slide block 301 slidably mounted on the outer surface of the cover 104, and the liquid storage tank 105 is mounted on the outer surface of the second slide block 301. Fixing blocks 302 are mounted on both sides of the outer surface of the cover 104, and a threaded rod 303 is rotatably connected between the two fixing blocks 302, passing through the interior of the second slide block 301 and threadedly connected thereto. A second servo motor 304 is mounted on the outer surface of one of the fixing blocks 302, and the output shaft of the second servo motor 304 is connected to the threaded rod 303.

[0028] When the second servo motor 304 is started, it drives the threaded rod 303 to rotate. Therefore, under the action of the threaded connection, it can drive the liquid storage tank 105 to move horizontally. Through the cooperation of the liquid storage tank 105 and the spraying mechanism 4, the outer surface of the steel component can be sprayed.

[0029] Preferably, the spraying mechanism 4 includes a U-shaped tube 401 disposed inside the cover 104, and a plurality of spray nozzles 402 are connected to the inner side of the U-shaped tube 401. A pump body 403 is mounted on the upper surface of the liquid storage tank 105. The input end of the pump body 403 communicates with the interior of the liquid storage tank 105, and the output end of the pump body 403 is connected to a connecting pipe 404. The end of the connecting pipe 404 is connected to the U-shaped tube 401.

[0030] Pump body 403 extracts the paint from storage tank 105 and transports it to U-shaped tube 401 through connecting pipe 404. Finally, it is sprayed from nozzle 402 onto the outer surface of steel component. The translation mechanism 3 drives nozzle 402 to move along the outer surface of steel component, thereby achieving the purpose of spraying the outer surface of steel component.

[0031] Preferably, guide posts 5 are installed on both sides of the upper surface of the cover 104, and the upper end of the guide post 5 slides through to the upper side of the U-shaped frame 102.

[0032] The guide column 5 can limit the movement of the cover 104, making it more stable to lift and lower.

[0033] Preferably, the outer surface of the cover 104 is provided with a through groove 6, and the connecting pipe 404 passes through the through groove 6 and is connected to the U-shaped pipe 401.

[0034] The through groove 6 provides a horizontal channel for the connecting pipe 404. Since the height of the through groove 6 is slightly larger than the diameter of the connecting pipe 404, only a small portion of the paint drifts outward, thus reducing the impact on the surrounding environment.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
