Description

Technical Field

[0001] This application relates to the field of high-altitude operations and surface treatment technology, and in particular to a high-altitude steel structure anti-corrosion spraying equipment. Background Technology

[0002] In modern infrastructure construction, high-altitude steel structures, with their outstanding load-bearing capacity and stability, are widely used in key areas such as bridge construction, high-rise building erection, and the construction of large industrial facilities. They not only support massive buildings and facilities but also resist various complex external forces, providing a solid and reliable foundation for people's production and daily life. With continuous technological advancements and social development, the application scope of high-altitude steel structures is expanding daily, playing a crucial role in promoting economic development and enhancing the urban image.

[0003] However, due to long-term and continuous exposure to a complex and ever-changing natural environment, high-altitude steel structures are subjected to the combined effects of various adverse factors such as ultraviolet radiation, rainwater erosion, chemical corrosion, and significant fluctuations in temperature and humidity. These adverse factors gradually damage the high-altitude steel structures, affecting their service life and safety.

[0004] To address the corrosion problem of high-altitude steel structures caused by complex natural environments, past methods have been relatively simplistic. One approach involved workers manually climbing the structure to inspect and grind it using simple hand tools, then applying anti-corrosion coating with handheld spray guns. Another method involved erecting temporary scaffolding or using aerial work platforms to allow workers to operate on the steel structure from a relatively stable platform. Yet another method involved suspending workers with ropes to reach specific work locations. While these methods can alleviate corrosion to some extent, they all rely on direct manual intervention at height.

[0005] In current technologies, over-reliance on manual labor for high-altitude operations has significant drawbacks. High-altitude operations are inherently dangerous, with workers constantly facing safety threats such as falls and collisions. Moreover, manual operation is easily affected by environmental factors, and may even be impossible to perform in adverse weather conditions, leading to low work efficiency. Utility Model Content

[0006] In order to improve the efficiency of high-altitude steel structure anti-corrosion spraying, this application provides a high-altitude steel structure anti-corrosion spraying equipment.

[0007] The high-altitude steel structure anti-corrosion spraying equipment provided in this application adopts the following technical solution:

[0008] A high-altitude steel structure anti-corrosion spraying device includes a drone body and an anti-corrosion paint spraying assembly mounted on the drone body. The anti-corrosion paint spraying assembly includes a paint storage tank, an atomizing nozzle, a paint delivery pipe connecting the paint storage tank and the atomizing nozzle, and a pump connected in series on the paint delivery pipe. The drone body has a landing gear at its bottom, a load-bearing plate on the landing gear, and a telescopic rod on the load-bearing plate. The atomizing nozzle is mounted on the movable end of the telescopic rod, and a camera is also mounted on the movable end of the telescopic rod. The atomizing nozzle is located to one side of the camera, and the spraying direction is consistent with the camera's recognition direction.

[0009] By adopting the above technical solution, during high-altitude steel structure anti-corrosion spraying operations, the drone flies to the high-altitude steel structure, and the movable end of the telescopic rod on the load-bearing plate moves the camera and atomizing nozzle closer to the target area. The camera identifies the high-altitude steel structure and clarifies the areas that need to be sprayed. Simultaneously, the pump delivers the anti-corrosion paint from the paint tank to the atomizing nozzle through the paint delivery pipe for spraying. Because the spraying direction of the atomizing nozzle is consistent with the direction identified by the camera, the spraying position can be accurately located. In this way, no human intervention is required for high-altitude operations, reducing the safety risks such as falls and collisions associated with high-altitude work, minimizing environmental interference with the operation, and improving the efficiency of high-altitude steel structure anti-corrosion spraying.

[0010] Optionally, the load-bearing plate is provided with a support plate, and one telescopic rod is provided on each side of the support plate. The movable ends of the two telescopic rods extend in opposite directions, and a grinder is provided on the movable end of the telescopic rod located on the side of the support plate away from the camera.

[0011] By adopting the above technical solution, telescopic rods can be arranged on both sides of the support plate set on the load-bearing plate, so that the movable ends of the two telescopic rods extend in opposite directions to achieve a larger range of operation coverage; at the same time, a grinding machine is set on the movable end of the telescopic rod on the side away from the camera, which can first grind the steel structure to improve the adhesion of the subsequent anti-corrosion paint spraying and further ensure the anti-corrosion quality of the high-altitude steel structure.

[0012] Optionally, the telescopic rod includes a sleeve vertically disposed on the side wall of the support plate and a polygonal adjusting rod slidably disposed inside the sleeve. The adjusting rod and the sleeve are slidably engaged along the length direction. A lead screw is rotatably disposed inside the sleeve along its own length direction. The adjusting rod is screwed onto the lead screw. A servo motor that drives the lead screw to rotate is disposed on the support plate.

[0013] By adopting the above technical solution, when position adjustment is required, the servo motor is activated, driving the lead screw to rotate. The lead screw engages with a polygonal adjusting rod threaded onto it, allowing the polygonal adjusting rod to slide along its length within the sleeve, thereby achieving the extension and retraction of the telescopic rod. This structural design makes the extension and retraction adjustment of the telescopic rod more precise and stable, enabling more accurate adjustment of the positions of the atomizing nozzle, camera, and grinder, thus improving the adaptability and operational accuracy of the high-altitude steel structure anti-corrosion spraying equipment under different working conditions.

[0014] Optionally, a fixed box is provided between the support plate and the sleeve. The end of the lead screw rotatably passes through the end wall of the sleeve and the end wall of the fixed box, and is rotatably connected to the inner wall of the fixed box. The servo motor is mounted on the fixed box, and its output shaft rotatably passes through the side wall of the fixed box and extends into the fixed box. The lead screw and the output shaft of the servo motor are arranged parallel to each other, and both are fitted with transmission gears. The transmission gears are located inside the fixed box, and the two transmission gears are rotatably meshed.

[0015] By adopting the above technical solution, when the servo motor starts, its output shaft rotates, driving the transmission gear sleeved on it to rotate. Since the two transmission gears mesh with each other, they further drive the transmission gear sleeved on the lead screw to rotate, causing the lead screw to rotate within the sleeve. The polygonal adjusting rod is threaded onto the lead screw and slides within the sleeve, thus realizing the telescopic movement of the polygonal adjusting rod within the sleeve. This structural design allows the servo motor to stably transmit power to the lead screw, ensuring smooth extension and retraction of the telescopic rod, improving the reliability and stability of the telescopic rod's movement. Simultaneously, the fixed box protects the transmission gears, reducing the risk of external debris affecting their normal operation.

[0016] Optionally, the pumping component includes an electric sprayer, an air tank, and an air supply pipe connecting the electric sprayer and the air tank. Both the electric sprayer and the air tank are mounted on a load-bearing plate, and the electric sprayer is connected in series on the paint supply pipe.

[0017] By adopting the above technical solution, the electric sprayer and air tank, acting as pumping components, allow the anti-corrosion paint to be smoothly delivered from the paint storage tank to the atomizing nozzle via the paint delivery pipe, effectively improving the operational efficiency of high-altitude steel structure anti-corrosion spraying. Simultaneously, the layout of the electric sprayer and air tank on a load-bearing plate facilitates the rational distribution of equipment weight and ensures the stability of equipment operation. The electric sprayer, as the actuator for spraying the anti-corrosion coating, employs a precision atomizing nozzle design. It can accurately adjust the spray flow rate, pressure, and spray shape according to instructions from the control system. Furthermore, the opening and closing of the sprayer and the adjustment of spray parameters are all intelligently controlled by the control system based on image recognition results and operational planning, achieving precise and uniform spraying of the anti-corrosion coating. The air tank stores the compressed gas required for the electric sprayer's operation and is equipped with a high-precision pressure sensor and safety valve. It can monitor the pressure inside the tank in real time, and automatically alarm and activate the safety pressure relief device when abnormal pressure occurs.

[0018] Optionally, a protective box is provided at the movable end of the telescopic rod where the camera is located. The camera is located inside the protective box, and the atomizing nozzle is located outside the protective box. A vertical insertion slot is provided on the side of the protective box facing the camera's recognition direction. A protective partition is installed in the insertion slot. A driving block is provided on the inner wall of the protective partition. A support block and a rotating motor are provided on the inner bottom wall of the protective box. A screw is vertically rotatably installed on the top of the support block. The screw passes through the driving block through a threaded connection. A cavity is provided inside the support block. The bottom end of the screw extends into the cavity. The output shaft of the rotating motor rotates and passes into the cavity. Bevel gears are fitted on the opposite ends of the output shaft of the rotating motor and the screw located in the cavity. The two bevel gears mesh with each other.

[0019] By adopting the above technical solution, the rotating motor is started, and the output shaft of the rotating motor drives the bevel gear on it to rotate. The meshing of the two bevel gears drives the screw to rotate, and the screw passes through a drive block via threads. This drive block causes the protective partition to rise and fall within the insertion slot, achieving automatic raising and lowering of the protective partition. When protection of the camera is needed, lowering the protective partition reduces damage to the camera from external objects, dust, and moisture, extending its service life. When protection is not needed, raising the protective partition reduces the impact on the camera's field of view and improves the stability of normal camera recognition.

[0020] Optionally, a stirring motor is installed on the bottom wall of the paint storage tank, and a stirring paddle coaxially connected to the output shaft of the stirring motor is rotatably installed inside the paint storage tank.

[0021] By adopting the above technical solution, during the anti-corrosion paint spraying process, the stirring motor drives the stirring paddle to rotate, mixing and stirring the anti-corrosion paint in the paint storage tank, thereby reducing the possibility of sedimentation and stratification of the anti-corrosion paint and improving the subsequent spraying effect.

[0022] Optionally, the top of the drone body is provided with a number of rotating blades, and a protective railing is provided on the top of the drone body for each rotating blade. The protective railing is arc-shaped, and its center coincides with the axis of rotation of the corresponding rotating blade.

[0023] By adopting the above technical solution, the guardrail is designed with an arc-shaped streamlined structure. This design can effectively resist the impact of foreign objects, minimize air resistance, reduce the risk of the rotating blades colliding with foreign objects during operation, improve the safety of the rotating blades, and ensure the normal flight of the drone.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. During high-altitude steel structure anti-corrosion spraying operations, the drone flies to the high-altitude steel structure. The movable end of the telescopic rod on the load-bearing plate moves the camera and atomizing nozzle closer to the target area. The camera identifies the high-altitude steel structure and clarifies the areas to be sprayed. Simultaneously, the pump delivers the anti-corrosion paint from the paint tank to the atomizing nozzle through the paint delivery pipe. Because the spraying direction of the atomizing nozzle is consistent with the direction identified by the camera, the spraying position can be accurately located. In this way, no human intervention is required for high-altitude operations, reducing the safety risks of falls and collisions, minimizing environmental interference with the operation, and improving the efficiency of high-altitude steel structure anti-corrosion spraying.

[0026] 2. Using the support plate set on the load-bearing plate, telescopic rods can be arranged on both sides, so that the movable ends of the two telescopic rods extend in opposite directions to achieve a larger range of operation coverage; at the same time, a grinder is set on the movable end of the telescopic rod on the side away from the camera, which can first grind the steel structure to improve the adhesion of the subsequent anti-corrosion paint spraying and further ensure the anti-corrosion quality of the high-altitude steel structure.

[0027] 3. When position adjustment is required, the servo motor is activated, driving the lead screw to rotate. The lead screw engages with a polygonal adjusting rod threaded onto it, causing the polygonal adjusting rod to slide along its length within the sleeve, thus achieving the extension and retraction of the telescopic rod. This structural design makes the extension and retraction adjustment of the telescopic rod more precise and stable, enabling more accurate adjustment of the positions of the atomizing nozzle, camera, and grinder, improving the adaptability and operational accuracy of the high-altitude steel structure anti-corrosion spraying equipment under different working conditions.

[0035] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0036] This application discloses a high-altitude steel structure anti-corrosion spraying equipment.

[0037] Reference Figure 1 A high-altitude steel structure anti-corrosion spraying equipment includes a drone body 1 and an anti-corrosion paint spraying component 2. The anti-corrosion paint spraying component 2 is installed on the drone body 1 and can follow the drone body 1 to the high-altitude steel structure to carry out anti-corrosion paint spraying operations, thereby improving work efficiency and reducing the risks of manual high-altitude operations.

[0038] Reference Figure 1The top of the drone body 1 is equipped with several rotating propellers 3. In this embodiment, six are used as an example. A protective railing 31 is installed on the top of the drone body 1 corresponding to each rotating propeller 3. The protective railing 31 is arc-shaped, and the center of the arc coincides with the rotation axis of the corresponding rotating propeller 3. The rotating propellers 3 provide lift for the drone, enabling it to fly in the air. The protective railing 31 is used to protect the rotating propellers 3 and reduce the risk of collision damage during flight. Moreover, the protective railing 31 is generally made of lightweight metal material, which can provide sufficient protection without adding too much weight.

[0039] Reference Figure 1 The drone body 1 has a landing gear 11 mounted on its bottom. The landing gear 11 is used to support the drone during takeoff and landing. The landing gear 11 is usually made of metal, such as aluminum alloy, which has high strength and light weight. It is tripod-shaped, and a load-bearing plate 4 is fixedly mounted on the landing gear 11. The load-bearing plate 4 is used to install other components. The load-bearing plate 4 is generally a metal plate with a flat surface to facilitate the installation and fixation of components.

[0040] Reference Figure 1 and Figure 2 The anti-corrosion paint spraying assembly 2 includes a paint storage tank 21, an atomizing nozzle 22, a paint delivery pipe 23, and a pumping component 24. The paint storage tank 21 stores the anti-corrosion paint and is mounted on the UAV body 1 to fit its shape. A stirring motor 211 is fixedly installed on the bottom wall of the paint storage tank 21. A stirring paddle 212, coaxially connected to the output shaft of the stirring motor 211, is rotatably installed inside the paint storage tank 21. The stirring motor 211 drives the stirring paddle 212 to rotate, stirring the anti-corrosion paint in the paint storage tank 21 to prevent sedimentation and ensure the uniformity of the anti-corrosion paint. The stirring paddle 212 can be propeller-shaped or blade-shaped. In this embodiment, a blade-shaped stirring paddle 212 is used to effectively stir the anti-corrosion paint in the paint storage tank 21.

[0041] Reference Figure 3 A support plate 41 is fixedly installed at the center of the top of the load-bearing plate 4. Reinforcing ribs 42 connect the opposing side walls of the support plate 41 to the load-bearing plate 4. A telescopic rod 5 is vertically installed on each opposing side wall of the support plate 41, with the movable ends of the two telescopic rods 5 extending in opposite directions. Each telescopic rod 5 includes a sleeve 51 and a polygonal adjusting rod 52. In this embodiment, the adjusting rod 52 is square. The adjusting rod 52 and the sleeve 51 slide along their length. A fixing box 43 is fixedly installed between the support plate 41 and the sleeve 51. A lead screw 511 is rotatably installed inside the sleeve 51 along its own length. The adjusting rod 52 is threadedly mounted on the lead screw 511.

[0042] Reference Figure 3The end of the lead screw 511 rotatably passes through the end wall of the sleeve 51 and the end wall of the fixed box 43, and is rotatably connected to the inner wall of the fixed box 43. A servo motor 44 is fixedly mounted on the outer wall of the fixed box 43 above the sleeve 51. The output shafts of the lead screw 511 and the servo motor 44 are parallel, and both are fixedly fitted with transmission gears 441. The transmission gears 441 are located inside the fixed box 43, and the two transmission gears 441 are rotatably meshed. The fixed box 43 serves to protect and fix the transmission components, and is generally a metal box. The transmission gears 441 transmit the power of the servo motor 44 to the lead screw 511, enabling the lead screw 511 to rotate. Through this transmission method, the servo motor 44 can stably drive the lead screw 511 to rotate, realizing the normal extension and retraction of the telescopic rod 5.

[0043] Reference Figure 4 The atomizing nozzle 22 is installed on the extended end of one of the adjusting rods 52 and is connected to the side and bottom wall of the paint storage tank 21 through a corrosion-resistant paint delivery pipe 23. A camera 6 is also installed on the extended end of the adjusting rod 52. A protective box 7 is fixedly installed on the extended end of the adjusting rod 52 where the camera 6 is located. The camera 6 is located inside the protective box 7, while the atomizing nozzle 22 is located outside the protective box 7, but the spraying direction of the atomizing nozzle 22 is consistent with the recognition direction of the camera 6.

[0044] Reference Figure 4 and Figure 5 The protective box 7 has a vertically oriented insertion slot 71 on the side facing the recognition direction of the camera 6. A protective partition 72 is installed in the insertion slot 71. A drive block 721 is bolted to the inner wall of the protective partition 72. A support block 73 and a rotating motor 74 are fixedly installed on the inner bottom wall of the protective box 7. A screw 731 is installed on the top of the support block 73 in a vertically rotatable manner. The screw 731 passes through the drive block 721 through the threaded rotation.

[0045] Reference Figure 5 The support block 73 has an internal cavity, and the bottom end of the screw 731 extends into the cavity. The output shaft of the rotating motor 74 rotates and passes through the cavity. Bevel gears 741 are fixedly fitted on the opposite ends of the output shaft of the rotating motor 74 and the screw 731 within the cavity, and the two bevel gears 741 mesh with each other. The rotating motor 74 drives the screw 731 to rotate via the bevel gears 741. When the screw 731 rotates, the drive block 721 moves up and down along the screw 731, thereby raising and lowering the protective partition 72. The protective partition 72 can be lowered when the camera 6 is not needed, blocking the camera 6 and preventing anti-corrosion paint and other substances from splashing onto the camera 6 and affecting its clarity; it can be raised when the camera 6 is needed, exposing the camera 6.

[0046] Reference Figure 1The pumping unit 24 includes an electric spray bottle 241, an air tank 242, and an air supply pipe 243 connecting the electric spray bottle 241 and the air tank 242. Both the electric spray bottle 241 and the air tank 242 are mounted on the load-bearing plate 4, and the electric spray bottle 241 is connected in series with the paint supply pipe 23. The electric spray bottle 241 is used to spray out the anti-corrosion paint, and the air tank 242 provides compressed air to the electric spray bottle 241, increasing the spray pressure. The air supply pipe 243 connects the electric spray bottle 241 and the air tank 242, allowing compressed air to be delivered from the air tank 242 to the electric spray bottle 241. The combination of the electric spray bottle 241 and the air tank 242 provides sufficient pressure, allowing the anti-corrosion paint to smoothly pass through the paint supply pipe 23 to the atomizing nozzle 22 and be sprayed out.

[0047] Reference Figure 1 The drone body 1 is equipped with an electrical control box 12, and all electrical components on the device are electrically connected to the electrical control box 12. The camera 6 can collect image information of the steel structure surface in real time. By observing the images, the operator can accurately control the drone and the telescopic rod 5, so that the atomizing nozzle 22 can accurately spray the steel structure. For example, when the camera 6 detects a severely corroded area on the steel structure surface, the operator can control the telescopic rod 5 to extend, so that the atomizing nozzle 22 can approach the area for focused spraying.

[0048] Reference Figure 1 A grinder 8 is installed at the extended end of the adjusting rod 52 located on the side of the supporting plate 41 opposite to the camera 6. The grinder 8 is used to grind the surface of the steel structure, removing rust and impurities so that the anti-corrosion paint can better adhere to the surface. The grinder 8 can be an electric grinder 8, which uses a motor to drive the grinding disc to rotate; or it can be a pneumatic grinder 8, which uses compressed air to drive the grinding disc to rotate. In this way, the surface of the steel structure can be pre-treated with the grinder 8 before the spraying operation, improving the spraying effect.

[0049] The implementation principle of the high-altitude steel structure anti-corrosion spraying equipment in this application embodiment is as follows: The high-altitude steel structure anti-corrosion spraying equipment uses a drone body 1 equipped with an anti-corrosion paint spraying component 2, which can quickly reach the high-altitude steel structure work site. The operator can control the movement of the drone and the telescopic pole 5 through the image information collected by the camera 6, so that the atomizing nozzle 22 can accurately spray the steel structure. Before spraying, a grinder 8 can be used to pre-treat the surface of the steel structure to improve the spraying effect. At the same time, the stirring motor 211 ensures the uniformity of the anti-corrosion paint in the paint storage tank 21, the guardrail 31 protects the rotating blade 3, and the protective partition 72 protects the camera 6. These designs improve the stability and reliability of the equipment, greatly improving work efficiency and reducing human risks compared with traditional manual high-altitude work methods.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
