Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular to a steel structure coating device. Background Technology

[0002] The processing of plate steel structures requires the use of a coating device to spray paint onto the plate steel structure. However, with existing coating devices, the paint tends to adhere to the surface of the processing table on which the plate steel structure is placed. When the next plate steel structure is coated, this reduces the processing quality of the steel structure by the coating device.

[0003] In related technologies, a search revealed a Chinese patent document (authorization announcement number CN217017078U) entitled "Anti-corrosion Coating Covering Device for Steel Structures," which includes a support plate, a fixed frame fixedly connected to the top of the support plate, an anti-corrosion coating storage tank on the top of the fixed frame, a guide pipe connected to one side of the anti-corrosion coating storage tank, a pump installed on the guide pipe, one end of the guide pipe inserted into the fixed frame and connected to a distribution pipe, a plurality of spray heads connected to the bottom of the distribution pipe; a diversion pipe provided at the bottom of the distribution pipe, a plurality of air outlet pipes connected to the bottom of the diversion pipe; and a support plate fixedly connected to one side of the fixed frame. The carrier plate has an air supply box on top, and a fan is installed inside the air supply box. One side of the air supply box is connected to one end of the diversion pipe through a connecting pipe, and the other side of the air supply box has an air inlet pipe with a filter at the inlet. Positioning mechanisms for positioning the steel structure are installed on both sides of the fixing frame. This utility model has fast spraying efficiency and improves the production efficiency of steel structures. However, the above patent does not consider that the paint is very easy to adhere to the surface of the processing table used to place the plate-shaped steel structure. When the next plate-shaped steel structure is sprayed with paint, it will reduce the processing quality of the steel structure by the coating device. Utility Model Content

[0004] The purpose of this invention is to provide a steel structure coating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure coating device, comprising: The connecting plate is hollow inside. The top surface of the connecting plate is connected to a conduit for conveying paint, and the bottom surface of the connecting plate is equipped with several nozzles for coating steel structures. The support frame has rotating columns embedded in both sides. The two rotating columns are connected to hollow support plates for steel structure coating. The two inner walls of the support plates are fixedly connected to positioning sleeves. The inner cavity of the positioning sleeves is slidably connected to positioning rods. The end face of the positioning rods is welded to a movable plate. The side of the movable plate is rotatably connected to a movable plate via a pin. The end faces of the two movable plates are rotatably connected to a transmission plate via a pin. The side of the transmission plate is connected to the moving end of an electric push rod. The two inner walls of the support frame are provided with positioning grooves for the positioning rods to be inserted. The cleaning component is located at the bottom of the support plate.

[0006] Preferably, a linear motor and a fixed frame are respectively provided on the two outer side walls of the support frame, and a sliding rod is welded to the inner wall of the fixed frame.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This steel structure coating device uses an external feeding device to introduce paint into a conduit. With the connection of a connecting plate, the paint is sprayed through several nozzles to coat the steel structure located on the top surface of a support plate. The paint easily adheres to the top surface of the support plate. When the steel structure is coated again, the paint on the top surface of the support plate easily adheres to the steel structure surface, reducing the coating quality. A rotating motor provides power, causing the support plate to rotate around a rotating column, thus flipping the support plate and preventing the paint on the support plate surface from adhering to the steel structure surface, thereby improving the coating quality of the steel structure. In this steel structure coating device, the moving end of the electric push rod drives the transmission plate to move during the movement. With the connection between the two movable plates and the moving plate, the positioning rod extends into the positioning groove along the path of the positioning sleeve. During the transmission process, the support plate after the flipping is completed is supported and fixed, which enhances the structural stability of the device's components. This steel structure coating device, thanks to the design of the cleaning components, can clean the bottom surface of the flipped support plate. An external water supply device introduces clean water into the connecting pipe, and under the connection of the cleaning plate, clean water is sprayed out through several high-pressure nozzles to clean the surface of the support plate, providing conditions for the support plate to support the steel structure, preventing the coating from adhering to the surface of the steel structure, thereby improving the coating processing quality of the steel structure. The set drive motor provides power to rotate the threaded rod, and the threaded block moves along the thread path of the threaded rod, adjusting the cleaning position of several high-pressure nozzles on the support plate and enhancing the cleaning effect.

[0016] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0017] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] Please see Figures 1 to 6 A steel structure coating device, in this embodiment including: The connecting plate 1 is hollow inside. The top surface of the connecting plate 1 is connected to the conduit 2 for conveying paint. The bottom surface of the connecting plate 1 is equipped with several nozzles for coating steel structures. The external feeding equipment introduces paint into the conduit 2. Under the connection of the connecting plate 1, the paint is sprayed out through several nozzles to coat the steel structure. A support frame 3 has rotating columns 4 embedded in both sides of it. Two adjacent rotating columns 4 are connected to hollow support plates 5 for steel structure coating. The inner wall of the support frame 3 fits into the support plates 5, and both ends of the support plates 5 are semi-circular, allowing them to rotate within the inner wall of the support frame 3. Both arc surfaces of the support plates 5 abut against the inner wall of the support frame 3. One end of a rotating column 4 is connected to the output shaft of a rotary motor via a coupling. The fixed end of the rotary motor is bolted to the support frame 3. Positioning sleeves 6 are embedded and fixedly connected to both inner walls of the support plates 5. The cavity is slidably connected to a positioning rod 7, and a movable plate 8 is welded to the end face of the positioning rod 7. The movable plate 8 is rotatably connected to a movable plate 9 via a pin. Both movable plates 9 are inclined. Both movable plates 9 are rotatably connected to a transmission plate 10 via a pin. The movable end of an electric push rod 11 is connected to the side of the transmission plate 10. The two inner side walls of the support frame 3 are provided with positioning grooves for the positioning rod 7 to be inserted. When the movable end of the electric push rod 11 retracts to the designated position, the two movable plates 8 abut against each other. When the movable end of the electric push rod 11 extends to the designated position, both positioning rods 7 extend into the two positioning grooves of the support frame 3. The cleaning component 18 is located at the lower part of the support plate 5.

[0020] Linear motors 13 and fixed frames 16 are respectively installed on the two outer side walls of the support frame 3. The fixed end of the linear motor 13 is connected to the support frame 3 by bolts. The side of the fixed frame 16 is welded to the support frame 3. A sliding rod 15 is welded to the inner wall of the fixed frame 16. A sliding plate 14 is slidably connected to the side of the sliding rod 15. Fixed plates 12 are welded to both ends of the connecting plate 1. Sufficient space is reserved between the nozzles at the bottom of the connecting plate 1 and the support plate 5 to provide conditions for the rotation of the support plate 5. The bottom surfaces of the two fixed plates 12 are respectively connected to the sliding plate 14 and the linear motor 13. The support frame 3 is connected to the bottom of the support frame 3, and a cleaning box 17 is welded thereon. The top of the cleaning box 17 is hollow, and the inner cavity size of the cleaning box 17 is the same as that of the support frame 3. The cleaning assembly 18 is set in the inner cavity of the cleaning box 17. Sufficient space is reserved between the cleaning assembly 18 and the support plate 5 to provide conditions for the rotation of the support plate 5. The cleaning assembly 18 includes several high-pressure nozzles 23 and a hollow cleaning plate 22. The several high-pressure nozzles 23 are installed on the top surface of the cleaning plate 22. Both ends of the cleaning plate 22 are slidably connected to the cleaning box 17. The thickness of the cleaning plate 22 is sufficient to ensure stable lateral movement within the cleaning tank 17, preventing relative rotation between the cleaning plate 22 and the cleaning tank 17. A threaded block 21 is welded to the bottom surface of the cleaning plate 22, and a threaded rod 20 is threadedly connected to the threaded block 21. Rotating blocks 19 are connected to both ends of the threaded rod 20. Both rotating blocks 19 are rotatably connected to the cleaning tank 17 via bearings. The output shaft of a drive motor is connected to the end face of one of the rotating blocks 19 via a coupling. The fixed end of the drive motor is connected to the cleaning tank 17 via bolts. The bottom wall of the cleaning plate 22 is connected to the connecting pipe 24. The side of the cleaning tank 17 is embedded and fixedly connected to the connecting pipe 24. The output shaft of the rotary motor rotates 180 degrees back and forth. The output shaft of the drive motor can be controlled by the controller to rotate to a specified number of revolutions and then rotate in the opposite direction to a specified number of revolutions, so that the threaded block 21 moves down along the path of the threaded rod 20. The connecting pipe 24 is reserved with sufficient length to provide conditions for the lateral movement of the cleaning plate 22. The outer wall of the cleaning tank 17 is equipped with a drain port with a solenoid valve, which can discharge the sewage in the cleaning tank 17.

[0021] To facilitate the flipping process, an external feeding device introduces paint into the conduit 2, allowing the paint to flow into the inner cavity of the connecting plate 1. The paint is then sprayed out through several nozzles to coat the steel structure located on top of the support plate 5. However, the paint easily falls onto the surface of the support plate 5. When recoating the steel structure, the paint on the support plate 5 readily adheres to the steel structure surface, reducing the coating quality. A rotating motor provides power, and with the connection of the rotating column 4, the support plate 5 can be flipped, causing the side of the support plate 5 without paint to rotate to the top, allowing the steel structure to be coated. The support plate 5 is rotated to the designated position, and the electric push rod 11 is activated. The moving end of the electric push rod 11 moves the transmission plate 10. With the connection of the movable plate 9 and the moving plate 8, the two positioning rods 7 can move along the inner cavity of the positioning sleeve 6, so that the two positioning rods 7 extend into the two positioning grooves of the support frame 3 to support and fix the support plate 5 after the flipping is completed. When it is necessary to flip the support plate 5, the two positioning rods 7 can be disengaged from the two positioning grooves to provide conditions for the flipping of the support plate 5.

[0022] For cleaning, when the side of the support plate 5 with the material attached is flipped to the bottom, the surface of the support plate 5 is cleaned by the cleaning component 18, providing conditions for continuous coating processing of the steel structure. The external water supply equipment introduces clean water into the connecting pipe 24. After the clean water flows through the inner cavity of the cleaning plate 22, it is sprayed out through several high-pressure nozzles 23 to clean the surface of the support plate 5. The drive motor provides power so that the threaded block 21 moves along the thread path of the threaded rod 20. During the transmission process, the cleaning position of several high-pressure nozzles 23 is adjusted to achieve thorough cleaning of the support plate 5. The water stains on the surface of the support plate 5 after cleaning can be treated by natural air drying, manual wiping by workers, or drying by oven. This is not part of the main innovation and will not be described in detail.

[0023] The electric actuator 11, linear motor 13, rotary motor, drive motor, and solenoid valve are all existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0024] The working principle of this utility model: When flipping, after coating the steel structure on the top surface of the support plate 5, the coating adheres very easily to the surface of the support plate 5. The rotary motor is started, so that the support plate 5 rotates around the rotating column 4 as the axis, so that the clean side of the support plate 5 can support the steel structure. After the support plate 5 is flipped to the designated position, the electric push rod 11 is started. With the connection of the transmission plate 10, two movable plates 9, and two moving plates 8, the positioning rod 7 extends down into the positioning groove along the path of the positioning sleeve 6 to provide support for the support plate 5. When cleaning, the lower part of the flipped support plate 5 needs to be cleaned. The external water supply equipment introduces clean water into the connecting pipe 24. With the connection of the cleaning plate 22, several high-pressure nozzles 23 spray clean water to clean the surface of the support plate 5 and remove the coating adhering to the surface of the support plate 5. The drive motor provides power to make the threaded block 21 move along the path of the threaded rod 20. During the transmission process, the position of several high-pressure nozzles 23 is moved so that the clean water sprayed by the high-pressure nozzles 23 can fully clean the support plate 5.
