Description

Technical Field

[0001] This utility model relates to the field of steel box girder coating technology, specifically a steel box girder coating device. Background Technology

[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges. They are generally used on bridges with large spans. Because their shape resembles a box, they are called steel box girders. During the manufacturing process, steel box girders require surface coating and anti-corrosion treatment to increase their service life.

[0003] Currently, when coating the upper surface of steel box girders, due to the large area, most coating is done using a gantry-type coating system. The system moves along the surface of the steel box girder evenly to spray the coating. However, if a large area needs to be covered, the nozzle needs to be moved and its position adjusted multiple times, and frequent waiting for local coatings to dry is required, resulting in low efficiency. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a steel box girder coating device.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a steel box girder coating device, including guide rails, two of which are symmetrically arranged. A slider is slidably mounted on each guide rail, and a mounting plate is installed on the upper surface of the slider. An inverted U-shaped mounting frame is fixed between the two mounting plates. The mounting plate is generally inverted U-shaped. A horizontally arranged spray plate is located below the mounting frame. Multiple nozzles are evenly spaced and installed on the lower surface of the spray plate. Both ends of the spray plate are fixedly... The device includes a limiting rod with both ends movably passing through the mounting frame. Two symmetrically arranged connecting blocks are fixed on one of the limiting rods. A movable plate is fixed to the bottom of the two connecting blocks. A rectangular groove is formed on the movable plate, and an arc-shaped groove is formed at the diagonal of the rectangular groove. A pushing block is rotatably arranged in the rectangular groove. The pushing block is Y-shaped and its end abuts against the rectangular groove. A vertically arranged rotating shaft is fixed to the middle end of the pushing block. A storage box is fixed to the top of the mounting frame and is connected to the spray plate through a conveying pipe.

[0006] Preferably, the side wall of the mounting bracket is fixedly provided with a horizontally arranged support plate below the movable plate, and a drive motor is fixedly provided on the support plate. The output end of the drive motor is coaxially fixed on the rotating shaft.

[0007] Preferably, a movable block is fixedly provided on the side wall of the movable plate, and a first support rod is fixedly provided on the side wall of the mounting frame, with the first support rod passing through the movable block.

[0008] Preferably, the side wall of the spray plate is fixedly provided with a U-shaped base plate, and an air jet plate is fixedly installed at the end of the base plate. The mounting bracket is fixedly provided with an L-shaped fixing plate above the base plate. A blower is fixedly installed on the fixing plate, and the output end of the blower is connected to the air jet plate. Second support rods are fixedly provided at both ends of the base plate, and the bottom of the fixing plate is movably inserted into the second support rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. While the nozzle moves along the steel box beam on the mounting frame, it can be driven by the limit rod to move back and forth quickly and in short intervals, covering a large area at once. This reduces the need for frequent adjustments to the nozzle position in traditional methods, resulting in a uniform coating thickness, avoiding local accumulation, and faster overall drying speed. It eliminates the need to wait for local coatings to dry frequently, greatly improving overall coating efficiency.

[0011] 2. Before spraying with the nozzle, the air jet plate first sprays the surface of the steel box girder to clean up the dust and other impurities accumulated on the surface, so as to avoid the impurities affecting the subsequent spraying effect and ensure good adhesion between the coating and the surface of the steel box girder.

[0018] 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a steel box girder painting device, including guide rails 1. Two guide rails 1 are symmetrically arranged. This device is installed indoors, not outdoors. Sliding sliders 11 are mounted on the guide rails 1. Mounting plates 12 are mounted on the upper surface of the sliders 11. An inverted U-shaped mounting bracket 13 is fixed between the two mounting plates 12. A horizontally arranged spray plate 15 is located below the mounting bracket 13. Multiple equally spaced nozzles 16 are mounted on the lower surface of the spray plate 15. Limiting rods 17 are fixed at both ends of the spray plate 15. The two ends of the 17 extend through the mounting frame 13. Two symmetrically arranged connecting blocks 21 are fixed on one of the limiting rods 17. A movable plate 2 is fixed at the bottom of the two connecting blocks 21. A rectangular groove 22 is opened on the movable plate 2. An arc groove 23 is opened at the diagonal of the rectangular groove 22. A pushing block 25 is rotatably arranged in the rectangular groove 22. The pushing block 25 is Y-shaped and its end abuts against the rectangular groove 22. A vertically arranged rotating shaft 24 is fixed at the middle end of the pushing block 25. A storage box 14 is fixed on the top of the mounting frame 13. The storage box 14 is connected to the spray plate 15 through a conveying pipe.

[0020] The side wall of the mounting bracket 13 is fixedly provided with a horizontally arranged support plate below the movable plate 2. A drive motor 26 is fixedly provided on the support plate. The output end of the drive motor 26 is coaxially fixed on the rotating shaft 24. The drive motor 26 mainly provides power for the rotation of the rotating shaft 24, so that the subsequent spray plate 15 drives the nozzle 16 to achieve a rapid short-distance movement effect.

[0021] A movable block 27 is fixedly provided on the side wall of the movable plate 2, and a first support rod 28 is fixedly provided on the side wall of the mounting frame 13, with the first support rod 28 passing through the movable block 27. The movable block 27 and the first support rod 28 mainly support the movable plate 2, so that the movable plate 2 can move back and forth stably.

[0022] A U-shaped base plate 3 is fixedly installed on the side wall of the spray plate 15. An air jet plate 31 is fixedly installed at the end of the base plate 3. An L-shaped fixing plate 32 is fixedly installed on the mounting bracket 13 above the base plate 3. A blower 33 is fixedly installed on the fixing plate 32. The output end of the blower 33 is connected to the air jet plate 31. Therefore, before the nozzle 16 sprays, the air jet plate 31 sprays the surface of the steel box beam one step ahead of the nozzle 16, so that the dust and other impurities accumulated on the surface are cleaned and removed, and the accumulation of impurities affects the effect of subsequent spraying.

[0023] The base plate 3 is fixedly provided with second support rods 34 at both ends, and the bottom of the fixed plate 32 is movably inserted into the second support rods 34. This arrangement allows the base plate 3, the jet plate 31 and the blower 33 to be gravity-supported on the mounting frame 13, so that the base plate 3, the jet plate 31 and the blower 33 can move stably with the mounting frame 13.

[0024] The mounting plate 12 is designed in an inverted U-shape. This design protects the slider 11 and prevents external impurities from entering and affecting its normal movement.

[0025] Working principle: During use, the steel box girder to be sprayed is moved between two symmetrically arranged guide rails 1. When spraying the surface of the steel box girder, the mounting frame 13 moves stably on the guide rails 1 via the bottom slider 11. This process allows the nozzle 16 to move along the steel box girder. During this process, the storage box 14 supplies material to the spray plate 15, so that the nozzle 16 performs the spraying operation on the surface of the steel box girder. The drive motor 26 can drive the rotating shaft 24 to rotate. During this process, the rotating shaft 24 rotates continuously, causing one end of the end push block 25 to abut against the side wall of the rectangular groove 22 in the movable plate 2. At this time, the movable plate 2 will move along the side of the rectangular groove 22 that is in contact, thereby the movable plate 2 drives the limit rod 17 to move via the connecting block 21. As the end of the push block 25 rotates into the arc groove 23, the other end of the push block 25 will abut against the other side of the rectangular groove 22. At this time, the movable plate 2 will be driven by the push block 25 to move in the opposite direction. Therefore, the movable plate 2 will drive the connecting block 21 to drive the limiting rod 17 back to its original position. Therefore, when the drive motor 26 is working, the limiting rod 17 can be directly controlled to drive the spray plate 15 to move back and forth quickly and repeatedly. Therefore, when the mounting frame 13 moves along the steel box beam to be sprayed, the nozzle 16 moves back and forth quickly with short intervals. The paint in the nozzle 16 is evenly covered on the target area by the translation. It can cover a large area at one time, avoid local accumulation, and make the overall drying speed faster and the coating thickness more uniform.

[0026] As the mounting bracket 13 moves horizontally on the guide rail 1 along with the slider 11, the blower 33 will start, and its output end will be connected to the jet plate 31. Therefore, before the nozzle 16 sprays, the jet plate 31 will spray the surface of the steel box beam one step ahead of the nozzle 16, so that the dust and other impurities accumulated on the surface are cleaned and removed, and the accumulation of impurities will not affect the effect of subsequent spraying.

[0027] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
