Description

Technical Field

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

[0002] In the construction industry, precast steel structures are frequently used to increase construction efficiency. To extend the service life of these structures, anti-corrosion treatment is often required on their surfaces. Applying anti-corrosion coatings necessitates the use of spraying equipment. Anti-corrosion spraying of steel structures is a crucial process for ensuring their long-term durability. Existing spraying equipment, especially large-scale equipment, typically has storage tanks. Due to the large amount of paint stored, prolonged standing can easily lead to layering or condensation. Current solutions involve using agitation and scrapers to prevent this, but scrapers can cause wear on the inner walls of the storage tank, affecting subsequent cleaning. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a spraying device for anti-corrosion treatment of steel structure surfaces in building construction. This addresses the issue that existing spraying devices, especially large ones, typically have storage tanks. Due to the large amount of paint stored, prolonged standing can easily lead to stratification or condensation. Current solutions use stirring and scrapers to prevent this, but the scrapers can easily cause wear on the inner wall of the storage tank, thus affecting subsequent cleaning.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a spraying device for anti-corrosion treatment of steel structure surfaces in building construction, comprising a mounting frame, a storage tank mounted on the mounting frame, a drive motor mounted above the storage tank, a stirring rod connected below the drive motor, a rubber roller connected to the outside of the stirring rod, a liquid pump connected to the bottom of the storage tank via a pipe, a material delivery pipe mounted above the liquid pump, an air pump mounted at the top of the mounting frame, an air delivery pipe mounted on the air pump, a second drive motor mounted on the outside of the mounting frame, and a take-up roller connected to the output end of the second drive motor via a synchronous belt, the take-up roller respectively winding up the material delivery pipe and the air delivery pipe, and a spray gun connected to the top of the material delivery pipe and the air delivery pipe.

[0005] The beneficial effects of this utility model are as follows: the drive motor drives the stirring rod and the rubber roller to rotate. While the rubber roller rotates with the stirring rod, it also rotates on its own to stir the coating by relying on the friction between the rubber roller and the inner wall of the storage tank. This method can effectively avoid the occurrence of coating dust or condensation. At the same time, the use of the rubber roller can effectively reduce the wear on the inner wall of the storage tank.

[0006] After the coating is completed, the second drive motor drives the take-up roller via the synchronous belt to take up the material conveying pipe and the air conveying pipe, ensuring the safe storage of the material conveying pipe and the air conveying pipe.

[0007] To facilitate the movement and fixation of the device:

[0008] As a further improvement to the above technical solution: the bottom of the mounting frame is equipped with casters, and a telescopic motor is installed in the lower middle part of the mounting frame, and the lower part of the telescopic motor is connected to a limit plate.

[0009] The beneficial effects of this improvement are: when spraying is required, the user can move the device to the designated position using the casters, and the telescopic motor will push the limit plate down to contact the ground and fix the position of the mounting bracket.

[0010] To facilitate paint addition:

[0011] As a further improvement to the above technical solution: the top of the storage hopper is provided with an end cap.

[0012] The beneficial effects of this improvement are: paint can be injected into the storage tank after the end cap is opened, and the end cap can seal the storage tank during use.

[0013] To facilitate mixing of the paint:

[0014] As a further improvement to the above technical solution: the rubber rollers are circumferentially distributed on the outside of the stirring rod.

[0015] As a further improvement to the above technical solution: the rubber roller and the inner wall of the storage barrel are arranged parallel to each other.

[0016] As a further improvement to the above technical solution: a bearing is installed at the connection between the stirring rod and the rubber roller.

[0017] The beneficial effects of this improvement are as follows: the drive motor drives the stirring rod and the rubber roller to rotate. While the rubber roller rotates with the stirring rod, it also rotates on its own axis by relying on the friction between the rubber roller and the inner wall of the storage tank. This method can effectively avoid the occurrence of paint dust or condensation. The bearing can effectively ensure the rotation effect of the rubber roller.

[0018] To facilitate fixing the position of the take-up roller:

[0019] As a further improvement to the above technical solution: the take-up roller and the mounting frame are connected by a bracket.

[0020] The beneficial effects of this improvement are: the connection between the take-up roller and the mounting frame can be made more reliable by the bracket, which in turn makes it easier for the drive motor to drive the take-up roller through the synchronous belt to take up the material conveying pipe and the air conveying pipe.

[0021] To facilitate fixing the mounting bracket position:

[0022] As a further improvement to the above technical solution, a wear-resistant layer is provided at the bottom of the limiting plate.

[0023] The beneficial effect of this improvement is that the wear-resistant layer can increase the service life of the limiting plate. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0031] like Figure 1-5As shown, a spraying device for anti-corrosion treatment of steel structure surfaces in building construction includes a mounting frame 1. A storage tank 2 is mounted on the mounting frame 1, and a drive motor 21 is mounted above the storage tank 2. A stirring rod 22 is connected below the drive motor 21, and a rubber roller 23 is connected to the outside of the stirring rod 22. A liquid pump 24 is connected to the bottom of the storage tank 2 via a pipe, and a delivery pipe 25 is mounted above the liquid pump 24. An air pump 3 is mounted at the top of the mounting frame 1, and an air delivery pipe 31 is mounted on the air pump 3. A second drive motor 4 is mounted on the outside of the mounting frame 1, and a take-up roller 41 is connected to the output end of the second drive motor 4 via a synchronous belt. The take-up roller 41 winds up various materials. The material conveying pipe 25 and the air conveying pipe 31 are connected at their top ends to a spray gun 5. A drive motor 21 drives a stirring rod 22 and a rubber roller 23 to rotate. While the rubber roller 23 rotates with the stirring rod 22, it also rotates on its own axis due to the friction between the rubber roller 23 and the inner wall of the storage tank 2, thus stirring the paint. This method effectively avoids paint dust or condensation. Simultaneously, the use of the rubber roller 23 effectively reduces wear on the inner wall of the storage tank 2. After spraying, a second drive motor 4 drives a take-up roller 41 via a synchronous belt to rewind the material conveying pipe 25 and the air conveying pipe 31, ensuring their secure storage. The bottom of the mounting frame 1... The mounting frame 1 is equipped with casters 11, and a telescopic motor 12 is installed in the lower middle part of the mounting frame 1. The lower part of the telescopic motor 12 is connected to a limit plate 13. When spraying is required, the user moves the device to the designated position using the casters 11. The telescopic motor 12 pushes the limit plate 13 down to contact the ground and fix the position of the mounting frame 1. The top of the storage tank 2 is provided with an end cap. After opening the end cap, paint can be injected into the storage tank 2. During use, the end cap can seal the storage tank 2. The rubber rollers 23 are circumferentially distributed on the outside of the stirring rod 22. The rubber rollers 23 and the inner wall of the storage tank 2 are arranged parallel to each other. A bearing is installed at the connection between the stirring rod 22 and the rubber rollers 23. Machine 21 drives the stirring rod 22 and rubber roller 23 to rotate. While the rubber roller 23 rotates with the stirring rod 22, it also rotates on its own axis due to the friction between the rubber roller 23 and the inner wall of the storage tank 2. This method can effectively avoid the occurrence of paint dust or condensation. The bearing can effectively ensure the rotation effect of the rubber roller 23. The winding roller 41 is connected to the mounting frame 1 by a bracket. The bracket can make the connection between the winding roller 41 and the mounting frame 1 more reliable, and thus facilitate the drive motor 4 to drive the winding roller 41 through the synchronous belt to wind up the conveying pipe 25 and the air conveying pipe 31. The bottom of the limiting plate 13 is provided with a wear-resistant layer, which can increase the service life of the limiting plate 13.

[0032] The working principle of this utility model is as follows: When using this device, the anti-corrosion coating is added into the storage tank 2. The drive motor 21 drives the stirring rod 22 and the rubber roller 23 to rotate. While the rubber roller 23 rotates with the stirring rod 22, it also rotates on its own axis due to the friction between the rubber roller 23 and the inner wall of the storage tank 2. This method can effectively avoid the occurrence of coating dust or condensation. At the same time, the use of the rubber roller 23 can effectively reduce the wear on the inner wall of the storage tank 2. When spraying is required, the user can move the device to the designated position using the casters 11. The telescopic motor 12 pushes the limit plate 13 down to contact the ground and fix the position of the mounting frame 1. After the movement is completed, the spray gun 5 is pulled to drive the material delivery pipe 25 and the air delivery pipe 31 to unfold. The liquid pump 24 injects paint into the spray gun 5 through the material delivery pipe 25, and the air pump 3 injects high-pressure gas into the spray gun 5 through the air delivery pipe 31, so that the steel structure can be sprayed. After the spraying is completed, the drive motor 4 drives the take-up roller 41 through the synchronous belt to rewind the material delivery pipe 25 and the air delivery pipe 31 to ensure the storage of the material delivery pipe 25 and the air delivery pipe 31.
