Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a painting device for steel structures in building construction. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of components such as beams, steel columns, and steel trusses made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, and super high-rise buildings.

[0003] The main functions of painting steel structures in building construction are as follows: Corrosion and rust prevention: Isolating the steel from air and moisture, thus slowing down corrosion. Extending lifespan: Reducing environmental damage to the steel structure and improving durability. Aesthetic decoration: Colors can be customized to enhance the building's appearance. Identification function: Using color to distinguish the purpose of components or warn of areas.

[0004] In related technologies, application number CN202121972434.X discloses a painting device for steel structures in building construction.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in Figure 1 A schematic diagram of a preferred embodiment of a painting device for steel structures in building construction provided by this utility model; Figure 2 for Figure 1 The diagram shows the structural schematic of the left view of the U-shaped frame section. Figure 3 for Figure 1 The diagram shows the overall three-dimensional structure of the device. A painting device for steel structures in building construction includes: a processing base 1, and a painting assembly 2 is provided on the top of the processing base 1.

[0023] The painting assembly 2 includes a painting chamber 21 disposed on the top of the processing base 1. A U-shaped frame 22 is disposed on the inner side of the painting chamber 21 and can slide up and down. A bidirectional spray nozzle 23 is disposed on the inner side of the U-shaped frame 22. A placement platform 24 is disposed on the left and right sides of the bottom of the inner wall of the painting chamber 21 and can be rotated.

[0024] With a U-shaped frame 22 that can slide up and down and a two-way spray nozzle 23, it is possible to uniformly spray paint steel structures of different heights.

[0025] A drive motor 25 is provided on the top of the processing base 1 and below the left placement platform 24. The output end of the top of the drive motor 25 is fixedly connected to the bottom end of the left placement platform 24. A belt structure 26 is provided on the output end of the drive motor 25. The bottom end of the right placement platform 24 is rotatably connected to the top of the processing base 1. The bottom of the periphery of the right placement platform 24 is sleeved with the inner side of the belt structure 26.

[0026] The rotation of the drive motor 25 can simultaneously drive the two placement platforms 24 to rotate, thereby cooperating with the up-and-down moving nozzles to complete the uniform painting of the steel structure. By setting two placement platforms 24, two steel structures can be painted at the same time, improving the painting efficiency. Multiple placement platforms 24 can also be added using the same belt structure 26 to achieve batch painting.

[0027] The inner side of the spray booth 21 is rotatably provided with a bidirectional threaded screw 27. The circumferential side of the bidirectional threaded screw 27 is provided with two threaded sleeves 28 that can move back and forth along its length. The bottom of the two threaded sleeves 28 is rotatably provided with a connecting plate 29. The bottom of the two connecting plates 29 is rotatably connected to the top of the U-shaped frame 22.

[0028] The rotation of the output end of the second motor 3 drives the rotation of the bidirectional threaded screw 27, which in turn drives the two threaded sleeves 28 to move inward first, causing the connecting plate 29 to rotate and drive the U-shaped frame 22 to move downward. When it moves to the bottom limit, the output end of the second motor 3 reverses, causing the U-shaped frame 22 to move upward, thus realizing repeated up and down movement, which enables the bidirectional spray head 23 to spray paint evenly on the surface of the steel structure; the connecting pipe at the top of the bidirectional spray head 23 is soft and long, which is used to meet the up and down movement of the U-shaped frame 22.

[0029] A second motor 3 is installed on the top of the spray booth 21. The output end of the second motor 3 is connected to the rear end of the bidirectional threaded screw 27 by a set of gears.

[0030] The bottom of the processing base 1 is equipped with a paint storage tank 4, and the top of the spray booth 21 is equipped with a pump 5. The pump 5's extraction pipe is connected to the back of the paint storage tank 4, and the pump 5's discharge pipe is connected to the top of the bidirectional spray head 23.

[0031] Filter blocks 6 are provided on the left and right sides of the bottom of the inner wall of the spray booth 21. Filter screens are provided on the inner side of the two filter blocks 6. Connecting pipes 7 are provided on the bottom of the opposite side of the two filter blocks 6. The bottom ends of the two connecting pipes 7 are respectively connected to the left and right sides of the paint storage tank 4. The bottom of the inner wall of the spray booth 21 is concave on both sides.

[0032] With the filter block 6 in place, excess paint will slide down the bottom of the inner wall of the spray booth 21 into the filter blocks 6 on both sides. After being filtered by the filter screen, the paint will flow back into the paint storage tank 4 through the connecting pipe 7, thereby improving the utilization rate of paint and reducing waste.

[0033] Drying fans 8 are installed on both the left and right sides of the top of the spray booth 21.

[0034] After spraying, the product can be quickly dried by turning on the drying fan 8, so that it can be put into use quickly.

[0035] The working principle of the painting device for steel structures in building construction provided by this utility model is as follows:

[0036] Step 1: When in use, place the steel structure on top of the two placement platforms 24, and drive the output of the drive motor 25 to rotate, causing the two placement platforms 24 to rotate simultaneously. At this time, the pump 5 works to spray the paint out from the bidirectional nozzle 23.

[0037] Step 2: The rotation of the output end of the second motor 3 drives the rotation of the bidirectional threaded screw 27, which in turn drives the two threaded sleeves 28 to move inward first, causing the connecting plate 29 to rotate and drive the U-shaped frame 22 to move downward. When it moves to the bottom limit, the output end of the second motor 3 reverses, causing the U-shaped frame 22 to move upward, thereby realizing repeated up and down movement, which can cause the bidirectional spray head 23 to spray paint evenly on the surface of the steel structure.

[0038] Step 3: With the setting of filter block 6, excess paint in the spray booth 21 will slide down the bottom of the inner wall of the spray booth 21 into the filter blocks 6 on both sides. After being filtered by the filter screen, the paint flows back into the paint storage tank 4 through the connecting pipe 7, thereby improving the utilization rate of the paint and reducing waste. Finally, the drying fan 8 can be turned on to dry it quickly for quick use.

[0039] Compared with related technologies, the painting device for steel structures in building construction provided by this utility model has the following beneficial effects:

[0040] By controlling the output of the drive motor 25 to rotate, the two placement platforms 24 can be rotated simultaneously, enabling multiple painting operations on a steel structure in a single operation. With the filter block 6 installed, excess paint in the spray booth 21 slides down the bottom of the inner wall of the spray booth 21 into the filter blocks 6 on both sides. After being filtered by the filter screen, the paint flows back into the paint storage tank 4 through the connecting pipe 7, thereby improving the utilization rate of the paint. The structure is simple and practical, which not only improves the painting efficiency but also reduces paint waste.
