Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-corrosion treatment equipment technology, and in particular to an anti-corrosion treatment device for steel structures. Background Technology
[0002] Steel structures, with their advantages of high strength, ease of processing, and recyclability, are widely used in construction, bridges, energy, and other fields. However, steel is susceptible to environmental corrosion, which not only reduces the structural load-bearing capacity but can also lead to safety accidents. Therefore, anti-corrosion treatment is crucial to ensuring the long-term stable service of steel structures. Manual painting is the mainstream method for anti-corrosion treatment of steel structures. Manual painting relies on workers holding spray guns and spraying each surface individually. During the painting process, workers need to frequently adjust the spray gun angle and control the paint flow, making the operation time-consuming and labor-intensive, resulting in slow progress. Furthermore, when changing the painting surface of steel components, multiple people need to work together using hoisting equipment, making the process cumbersome and time-consuming, thus extending the overall construction cycle.
[0003] To address the efficiency issues of manual coating, patent CN220294995U discloses a steel structure surface anti-corrosion treatment device, comprising two fixed seats and a frame. The top of the frame is equipped with a horizontally movable air-drying nozzle and a spraying nozzle. Each fixed seat has two electric telescopic rods embedded inside, and a support block is installed between the two electric telescopic rods. Each support block has a horizontally distributed rotating shaft rotatably connected to its inner side, and one of the rotating shafts is driven by a flipping motor. The end of each rotating shaft away from the support block extends outside the fixed seat and is fixedly connected to a positioning device.
[0004] The aforementioned anti-corrosion treatment equipment can improve the coating effect on steel plates; however, the positioning device is mounted on a fixed base via a support block, and the distance between the two fixed bases is fixed, making it impossible to adjust the distance between the positioning devices. This results in the anti-corrosion treatment equipment being unable to adapt to steel components of different lengths, leading to low applicability of the equipment. Utility Model Content
[0005] This utility model proposes a steel structure anti-corrosion treatment device, which solves the problems of the inability to adjust the spacing of the positioning device and the low applicability of the anti-corrosion treatment device in the prior art.
[0006] The technical solution of this utility model is implemented as follows: A steel structure anti-corrosion treatment device includes a spraying mechanism and a switching mechanism. The spraying mechanism is located above the switching mechanism. The switching mechanism includes a base with side guide grooves on both the front and rear sides. A bidirectional lead screw is installed in each side guide groove. Two movable frames, driven by the bidirectional lead screw, are mounted on the base. Each movable frame has a rotatable rotating plate on its opposite side, and two sets of movable positioning clamps are respectively mounted on the opposite side of the rotating plates. Rotation of the bidirectional lead screw can move the two movable frames closer together or further apart, adjusting the distance between the positioning clamps on the two movable frames, thus making the device applicable to steel structures of different sizes.
[0007] In a preferred embodiment, the lower part of the movable frame extends into the side guide groove, and the lower part of the movable frame is threadedly connected to the bidirectional lead screw in the side guide groove.
[0008] In a preferred embodiment, a side groove is provided on the upper surface of the base, and two pulleys are provided in the side groove. The two pulleys are connected by a belt for transmission. Two bidirectional lead screws in the two side guide grooves are respectively connected to the two pulleys. A second motor is installed on one side of the base, and the output shaft of the second motor is connected to one of the pulleys.
[0009] In a preferred embodiment, the spraying mechanism includes a frame, the lower end of which is fixedly connected to a base. A movable box that can move laterally is provided on the frame, and three sets of spray nozzles for spraying anti-corrosion paint are installed below the movable box.
[0010] As a preferred embodiment, three sets of feed valves are installed at the rear of the mobile box, and the three sets of feed valves are respectively connected to three sets of nozzles.
[0011] As a preferred embodiment, a fan is installed on one side of the mobile box, with the fan outlet facing the steel structure surface. An electric heating wire mesh is installed at the fan outlet, and hot air blown by the fan onto the electric heating wire mesh can be generated to dry the sprayed surface of the steel structure.
[0012] In a preferred embodiment, a guide groove is provided on the upper part of the frame, a threaded screw is installed in the guide groove, a drive slider that can slide along the guide groove is threadedly connected to the threaded screw, the drive slider is fixedly connected to the moving box, and a first motor is installed on one side above the frame, the output shaft of the first motor is connected to the threaded screw.
[0013] In a preferred embodiment, a fixed plate is installed above the movable frame, and a fourth motor is installed on the side of the fixed plate near the movable frame, with the output shaft of the fourth motor connected to the rotating plate.
[0014] In a preferred embodiment, a central groove is provided in the middle of the rotating plate, and a bidirectional lead screw is installed in the central groove. A set of inner sliders that can slide along the central groove are threaded to both sides of the bidirectional lead screw. The inner sliders are fixedly connected to the positioning clamp. A third motor is installed above the rotating plate, and the output shaft of the third motor is connected to the bidirectional lead screw.
[0015] As a preferred embodiment, a rubber anti-slip pad is installed on the opposite side of the positioning clamp.
[0016] The beneficial effects of this utility model are as follows: 1. By designing a switching mechanism, the spacing between the left and right positioning clamps can be adjusted according to the actual length of the steel structural component through the coordinated movement of two sets of moving frames, achieving rapid adaptation to steel components of different lengths. During positioning, the two sets of positioning clamps move towards each other, generating a stable clamping force to securely fix the steel component from both ends, preventing displacement during the spraying process. After single-sided spraying is completed, the rotating plate rotates smoothly, causing the steel component fixed on it to flip over, allowing the unsprayed surface to quickly switch to the working position.
[0017] 2. By designing a spraying mechanism, a threaded screw drives a slider to move laterally along a guide groove, thereby smoothly moving a moving box equipped with three sets of spray heads. This allows for efficient anti-corrosion spraying of steel structural components. The three sets of spray heads correspond to the primer, intermediate coat, and topcoat, respectively, enabling sequential spraying of the base layer, intermediate layer, and surface layer to construct a complete anti-corrosion coating system. After spraying, a fan blows air over an electric heating wire mesh to generate hot air, which then blows onto the paint surface, shortening the curing time. Compared to traditional manual operation, this method is simpler to operate, has higher spraying efficiency, and produces a more uniform coating thickness. Attached Figure Description

[0021] 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.
[0022] Example 1, as Figure 1 , Figure 2 As shown, a steel structure anti-corrosion treatment device includes a spraying mechanism 1 and a switching mechanism 2. The spraying mechanism 1 is located above the switching mechanism 2. The switching mechanism 2 includes a base 21. Side guide grooves 22 are respectively opened on the front and rear sides of the base 21. A bidirectional lead screw 23 is installed in the side guide grooves 22. Two movable frames 25 are provided on the base 21, which can move relative to each other under the drive of the bidirectional lead screw 23. A rotatable rotating plate 27 is provided on the opposite side of each of the two movable frames 25. Two sets of mutually movable positioning clamps 214 are respectively provided on the opposite side of the two rotating plates 27. Through the coordinated movement of the two sets of movable frames 25, the distance between the left and right positioning clamps 214 can be adjusted according to the actual length of the steel structure component, so as to achieve rapid adaptation to steel components of different lengths.
[0023] Furthermore, such as Figure 4 As shown, the lower sides of the movable frame 25 extend into the side guide groove 22, and the lower part of the movable frame 25 is threadedly connected to the bidirectional lead screw 23 in the side guide groove 22. The opening of the side guide groove 22 faces the outside of the base 21, effectively preventing the paint sprayed by the spraying mechanism 1 from entering the side guide groove 22 and affecting the connection between the bidirectional lead screw 23 and the movable frame 25; the rotation of the bidirectional lead screw 23 can drive the two movable frames 25 to move relative to or in opposite directions, thereby realizing the adjustment of the distance between the two movable frames 25.
[0024] Furthermore, a side groove 210 is formed on one side of the upper surface of the base 21, and two sets of pulleys 28 are arranged in the side groove 210. The two sets of pulleys 28 are connected by a belt 29 for transmission. Two sets of bidirectional lead screws 23 are respectively connected to the two sets of pulleys 28. A second motor 24 is installed on one side of the base 21, and the output shaft of the second motor 24 is connected to one of the pulleys 28. The arrangement of the pulleys 28 and the belt 29 makes the bidirectional lead screws 23 in the two side guide grooves 22 rotate synchronously, ensuring the smooth movement of the moving frame 25.
[0025] Example 2, based on Example 1, provides a steel structure anti-corrosion treatment device. The spraying mechanism 1 includes a frame 11 mounted on a base 21. A laterally movable box 14 is mounted on the frame 11, and three sets of spray nozzles 15 for spraying anti-corrosion paint are installed below the movable box 14. Three sets of feed valves 110 are installed behind the movable box 14, each connected to one of the three sets of spray nozzles 15. The lower end of the frame 11 is fixedly connected to the base 21. The three sets of spray nozzles 15, from left to right, are a base coat spray nozzle, an intermediate coat spray nozzle, and a top coat spray nozzle. When the movable box 14 moves laterally, by sequentially activating each spray nozzle 15, the primer, intermediate coat, and top coat can be supplied sequentially, completing the spraying operations for the base coat, intermediate coat, and top coat in sequence.
[0026] Furthermore, such as Figure 5 As shown, a fan 16 is installed on one side of the mobile box 14. The air outlet of the fan 16 faces the surface of the steel structure. An electric heating wire mesh 19 is installed at the air outlet of the fan 16. Hot air blown by the fan 16 onto the electric heating wire mesh 19 can generate hot air to dry the painted surface of the steel structure. The hot air generated by the fan 16 blowing air onto the electric heating wire mesh 19 dries the paint surface and accelerates its curing.
[0027] Furthermore, such as Figure 3 As shown, a guide groove 12 is provided above the upright frame 11. A threaded screw 17 is installed in the guide groove 12, and a drive slider 18 that can slide along the guide groove 12 is threadedly connected to the threaded screw 17. The drive slider 18 is fixedly connected to the movable box 14. A first motor 13 is installed on one side of the upper part of the upright frame 11, and the output shaft of the first motor 13 is connected to the threaded screw 17. When the first motor 13 is started, it can drive the threaded screw 17 to rotate, thereby driving the drive slider 18 to move along the guide groove 12, realizing the movement of the movable box 14.
[0028] Furthermore, a fixed plate 26 is installed above the movable frame 25. A fourth motor is installed on the side of the fixed plate 26 near the movable frame 25, and the output shaft of the fourth motor is connected to the rotating plate 27. This allows both sets of fourth motors to be connected to a synchronous controller, enabling the synchronous operation of the two sets of fourth motors to be controlled by the synchronous controller.
[0029] Furthermore, such as Figure 6As shown, a central groove 211 is provided in the middle of the rotating plate 27. A double-acting lead screw 212 is installed in the central groove 211. A set of inner sliders that can slide along the central groove 211 are threaded to both sides of the double-acting lead screw 212. The inner sliders are fixedly connected to the positioning clamp 214. A third motor 213 is installed above the rotating plate 27. The output shaft of the third motor 213 is connected to the double-acting lead screw 212.
[0030] Furthermore, a rubber anti-slip pad is installed on the opposite side of the positioning clamp 214. The rubber anti-slip pad can increase the friction with the steel component, making it less likely for the steel component to slip when clamped.
[0031] In practical use, the working principle of this utility model is as follows: During operation, the second motor 24 is first started to drive the pulley 28 to rotate. The pulley 28 drives another set of pulleys 28 to rotate via the belt 29, thus enabling the synchronous rotation of the two sets of pulleys 28 to achieve the synchronous rotation of the two sets of bidirectional lead screws 23. The bidirectional lead screws 23 drive the two sets of moving frames 25 to move towards each other along the side guide groove 22. The spacing between the left and right sets of positioning clamps 214 is adjusted according to the length of the steel structure to achieve rapid adaptation of steel components of different lengths. Then, the two sides of the steel component are placed between the left and right sets of positioning clamps 214. Next, the third motor 213 is started to drive the bidirectional lead screw 212 to rotate. The two sets of positioning clamps 214 slide along the central groove 211 to clamp the two ends of the steel component. After the steel components are fixed, the spraying pump can be connected to the feed valve 110 in advance, so that the spraying pump can draw the anti-corrosion paint in the paint tank and transfer it to the spray nozzle 15 for spraying. During spraying, the first motor 13 is started to drive the threaded screw 17 to rotate, which drives the drive slider 18 to slide along the guide groove 12, so that the moving box 14 and the three sets of spray nozzles 15 below it move laterally. The primer, intermediate paint and topcoat are supplied in sequence through the three sets of spray nozzles 15, and the spraying of the base layer, intermediate layer and surface layer are completed in sequence. After the spraying is completed, the fan 16 blows hot air to the electric heating wire mesh 19 to dry the paint surface and accelerate curing. During the accelerated curing, the moving box 14 is also moved laterally so that the hot air can cover the sprayed surface. After one side has cured, the fourth motor is started to drive the rotating plate 27 to rotate, which will flip the steel component to switch to the uncoated side. The above spraying and curing process is repeated until the anti-corrosion treatment of the entire steel component is completed.
