Description

Technical Field

[0001] This invention relates to the field of spraying construction platform technology, specifically to a construction spraying anti-corrosion and fireproof coating construction device. Background Art

[0002] The architectural coating spraying process uses mechanical atomization equipment to uniformly coat the building surface with materials that have anti-corrosion and fireproof functions, forming a continuous and dense protective layer. This effectively blocks corrosive media (such as moisture and pollutants) and heat radiation from eroding the building structure. The necessity of this process stems from the protection requirements of building components in complex environments: on the one hand, long-term exposure of exterior walls to ultraviolet radiation, temperature changes, and chemical pollutants can easily lead to problems such as steel corrosion and concrete carbonization; on the other hand, in fire scenarios, load-bearing components (such as steel beams and concrete columns) that have not been protected will rapidly lose their mechanical properties under high temperatures, leading to a significant increase in the risk of structural collapse.

[0003] Current mainstream processes are dominated by airless spraying and air-assisted spraying. The former uses a high-pressure pump to achieve ultra-fine atomization of the coating, which is suitable for efficient construction on large flat substrates. The latter uses compressed air to assist atomization, improving the coating homogeneity and interfacial adhesion in complex structural corner areas. Since architectural coating spraying relies on atomization technology to atomize the coating and spray it onto the substrate, the atomized particles are easily constrained by aerodynamic characteristics. Under the action of wind, disordered diffusion and abnormal deposition are likely to occur. Wind disturbance not only changes the trajectory of particle movement, but also causes uneven coating dispersion and reduced interfacial bonding, resulting in defects such as localized excessive thinness, micropores, and deterioration of leveling properties in the coating. These structural hazards directly destroy the continuous and dense characteristics of the protective coating, resulting in a significant reduction in the anti-corrosion barrier effect and fireproof and heat insulation performance, and a significant increase in subsequent repair costs. Therefore, we propose an application device for architectural spraying of anti-corrosion and fireproof coatings. Summary of the Invention

[0004] One of the technical problems to be solved by this application is that since architectural coatings rely on atomization technology to atomize the coating and spray it onto the substrate, the atomized particles are easily constrained by aerodynamic characteristics. Under the action of wind, they are prone to disordered diffusion and abnormal deposition. Wind disturbance not only changes the trajectory of particle movement, but also causes uneven dispersion of coating and a decrease in interfacial bonding.

[0012] In some embodiments, the opening and closing component includes a support rod disposed at the top of the positioning rod. The support rod and the positioning rod are respectively provided with a connecting groove and a guide groove, and the connecting groove and the guide groove are interconnected. Rotating blocks are rotatably disposed at both ends of the connecting groove. A limiting block is disposed inside the rotating chamber. A traction rope is disposed on the sliding plate. The traction rope passes sequentially through the limiting block, the guide groove in the positioning rod, and the connecting groove in the support rod, and is guided by the rotating blocks at both ends of the connecting groove before being led out. The led-out traction rope is connected to the first guide plate and the second guide plate, respectively, and the traction rope passes through the side wall of the rotating chamber and is movably connected to the side wall of the rotating chamber.

[0015] This invention has at least the following beneficial effects:

[0016] 1. The guide plate in this device can dynamically adjust its angle according to the wind direction, forming an effective wind barrier and significantly reducing the interference of crosswinds on the paint mist. This directly ensures the uniform distribution and precise adhesion of the paint on the wall surface, reducing paint scattering, uneven accumulation, or dripping caused by wind. Ultimately, it achieves a smoother, more uniform coating effect that meets design requirements. Effectively blocking wind can significantly reduce the ineffective scattering and loss of paint in the air. This means that the amount of paint required to spray the same area is reduced, directly lowering material costs and reducing the trouble and cost of cleaning up scattered paint. Finally, the design of the positioning rod driving the guide plate to rotate around the spray gun axis allows the wind-blocking angle to be adjusted flexibly in real time with the wind direction. There is no need to frequently stop construction to manually change the orientation or position of the entire equipment, greatly improving the adaptability and continuity of construction under changing wind conditions and shortening the overall operation time.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1-8 This invention provides a technical solution: a construction spraying device for anti-corrosion and fireproof coatings, comprising a movable frame 1, an electric guide rail 2, a movable base 3, and a spray gun 4. A positioning rod 5 is mounted on the movable base 3. A first guide plate 51 and a second guide plate 52 are rotatably mounted on the positioning rod 5. Multiple torsion springs 53 are mounted on the positioning rod 5 and are respectively connected to the first guide plate 51 and the second guide plate 52. A flow guiding and steering unit 6 is mounted on the movable base 3 and is connected to the positioning rod 5, used to drive the spray gun according to wind direction. The movable positioning rod 5 rotates around the axis of the spray gun 4 to adjust the wind-blocking angle of the first guide plate 51 and the second guide plate 52 relative to the spray gun 4; the movable seat 3 is also provided with an angle adjustment unit 9, which is connected to the first guide plate 51 and the second guide plate 52 respectively, and is used to adjust the included angle between the first guide plate 51 and the second guide plate 52 according to the wind force. During operation, the movable frame 1 drives the electric guide rail 2 to rise and fall. After reaching the specified height, the electric guide rail 2 drives the movable seat 3 and the spray gun 4 located on the movable seat 3 to work to spray paint.

[0030] The airflow guiding and steering unit 6 includes an airflow guide 7 mounted on the movable seat 3. The airflow guide 7 drives the first airflow guide plate 51 and the second airflow guide plate 52 to block the airflow blowing towards the spray gun 4 in a windy environment. The movable seat 3 is provided with a reversing component 8, which is used to adjust the wind-blocking angle of the first airflow guide plate 51 and the second airflow guide plate 52 relative to the spray gun 4.

[0031] The guide member 7 includes an annular groove 72 formed on the movable seat 3, an annular plate 71 is rotatably disposed in the annular groove 72, the annular plate 71 is connected to the positioning rod 5, a rotating chamber 73 is rotatably disposed in the annular groove 72, and a connecting plate 74 connected to the annular plate 71 is disposed on the rotating chamber 73.

[0032] The reversing component 8 includes a rotating rod 81 rotatably mounted on the movable seat 3. The rotating rod 81 passes through the movable seat 3 and is connected to the rotating chamber 73. An air collecting pipe 82 is provided at the end of the rotating rod 81 away from the rotating chamber 73. Fixed plates 83 are provided at both ends of the air collecting pipe 82. A wind direction rod 84 is provided on the fixed plate 83. A wind direction plate 85 is provided on the wind direction rod 84. A cylinder 86 is provided at the same end of the wind direction rod 84 and the wind direction plate 85.

[0033] In windy conditions, the airflow pushes the wind vane 85 to rotate the wind vane 84 around the rotating rod 81. As the rotating rod 81 rotates, it drives the rotating chamber 73 and the annular plate 71 connected to the rotating chamber 73 to rotate. As the annular plate 71 rotates, it drives the guide plate 1 51 and guide plate 2 52 to move, so that they are aligned with the airflow direction to protect the spray gun 4 during the spraying process and prevent the atomized paint from being swept away by the airflow, resulting in uneven spraying. At the same time, the cylindrical part 86 at the end of the wind vane 84 makes the wind vane 84 more stable when the airflow blows, reducing the vibration of the guide plate 1 51 and guide plate 2 52, thereby improving the protective effect.

[0034] The V-shaped angle formed between guide plate 1 51 and guide plate 2 52 forms a gradually narrowing flow channel through geometric constraints, forcing the airflow to accelerate axially and suppressing paint diffusion. At the same time, when the high-speed airflow passes through the guide plate, the local static pressure decreases, forming a negative pressure zone that adsorbs and stabilizes the trajectory of paint particles. Furthermore, the lateral wind impact energy is decomposed by the guide plate into harmless longitudinal airflow and normal resistance, avoiding direct interference with the core area of ​​the spray. The directional airflow guidance reduces particle deviation, significantly improves the consistency of thickness distribution, avoids defects such as uneven surfaces and streaks, suppresses paint scattering and overspraying, reduces ineffective losses, and achieves efficient resource utilization.

[0035] By directly driving the airflow to link the wind vane 85 and wind bar 84, the system senses and tracks wind direction changes in real time, automatically adjusting the guide vane to face the airflow direction to achieve the optimal windbreak angle. This dynamic calibration is completed without manual intervention, ensuring that the atomized paint remains within the effective protection range of the guide vane during spraying. This significantly reduces uneven spraying caused by paint being swept away by airflow. Furthermore, the mechanical linkage design directly translates wind direction changes into guide vane angle adjustment, resulting in faster response times. Compared to traditional manual adjustment or electric drive systems, this reduces signal transmission and execution delays, making it particularly suitable for... In scenarios involving sudden changes in wind direction, this system avoids protection failure due to response lag. Furthermore, by utilizing the aerodynamic characteristics of the cylinder 86, it generates a vortex damping effect when the airflow impacts, counteracting the swing inertia of the wind vane 84. This reduces the high-frequency micro-amplitude vibration of the guide plate caused by the vibration of the wind vane 84, preventing the protection angle from shifting. Finally, the guide plate maintains a vertical interception state directly facing the airflow, maximizing the wind barrier area, weakening the lateral shear force of the airflow on the paint mist, preventing the disordered diffusion of paint particles caused by airflow disturbance, improving the paint's adhesion to the wall, and reducing the pollution of surrounding equipment by drifting paint.

[0036] The angle adjustment unit 9 includes an adjustment component 10 disposed in the rotating chamber 73. The adjustment component 10 is used to adjust the included angle between the first guide plate 51 and the second guide plate 52. The air collection pipe 82 is provided with a power component 11, which provides power for the operation of the adjustment component 10. The positioning rod 5 is provided with an opening and closing component 12, which is used to control the deflection of the first guide plate 51 and the second guide plate 52 to adjust the included angle between them.

[0037] The adjusting component 10 includes a rotating shaft 101 rotatably disposed within a rotating rod 81. Both ends of the rotating shaft 101 pass through the rotating rod 81 and extend into the air collection pipe 82 and the rotating chamber 73, respectively. A sliding plate 102 is slidably disposed at one end of the rotating shaft 101 within the rotating chamber 73, and a positioning plate 103 is disposed at the other end of the rotating shaft 101 within the rotating chamber 73. A plurality of deflecting rods 104 are rotatably disposed on the positioning plate 103, and centrifugal balls 105 are disposed at the ends of the deflecting rods 104. A connecting seat 106 is disposed on both the sliding plate 102 and the deflecting rods 104, and a connecting rod 107 is disposed on the connecting seat 106.

[0038] The power component 11 includes a power shaft 111 disposed between two wind vanes 84. Both ends of the power shaft 111 are rotatably connected to the fixed plate 83. Power blades 112 are disposed on the power shaft 111. Power gears 113 are disposed on the power shaft 111. The rotating shaft 101 is located inside the air collection pipe 82 and is movably disposed with a transmission gear 114 that meshes with the power gear 113.

[0039] During the spraying process, the power blade 112 rotates under the push of the airflow, thereby driving the power shaft 111 to rotate. The rotation of the power shaft 111 drives the power gear 113 mounted on it to rotate. At the same time, the rotation of the power gear 113 drives the transmission gear 114 meshing with it to rotate. The rotation of the transmission gear 114 drives the rotating shaft 101 to rotate. The rotation of the rotating shaft 101 drives the positioning plate 103, the deflection rod 104, and the centrifugal ball 105 on the deflection rod 104 to rotate. When the wind force increases and the rotation speed of the power blade 112 increases, the rotation speed of the rotating shaft 101 increases synchronously, making the centrifugal ball 105 subjected to a greater centrifugal force during the rotation process, which in turn drives the deflection rod 104 to deflect. When the deflection rod 104 deflects, it reaches the connecting seat 106 through the connecting rod 107 and moves on the rotating shaft 101.

[0040] When the power blade 112 is driven to rotate by wind, its rotational speed is positively correlated with the wind force. After being transmitted to the rotating shaft 101 through the gear set, the centrifugal force of the centrifugal ball 105 changes dynamically. When the centrifugal force increases, the deflection rod 104 drives the connecting rod 107 to push the connecting seat 106 backward, thereby causing the traction rope 125 to be stretched. Finally, the included angle between the first guide plate 51 and the second guide plate 52 automatically expands, forming a wider wind barrier and enhancing the interception capability of strong winds. At the same time, the expansion of the guide plate included angle during strong winds can disperse the wind pressure impact, and the increase in centrifugal force of the centrifugal ball 105 forms a dynamic balance with the increase in wind force, preventing the system from overloading and shaking due to sudden changes in wind force. The rigid connection of the gear set, rotating shaft 101 and connecting rod 107 reduces the vibration amplitude of the transmission components at high speeds, ensuring the continuity and accuracy of the guide plate angle adjustment.

[0041] The powered blade 112 is driven to rotate directly using airflow energy, requiring no external energy input. Through the meshing transmission between the powered shaft 111 and the gear set, wind force changes are converted into rotational speed changes of the rotating shaft 101. This short transmission path and high efficiency ensure rapid transmission of wind signals and avoid energy loss. Meanwhile, the centrifugal ball 105 generates centrifugal force as the rotational speed of the shaft 101 changes. When the wind force increases, the rotational speed of the powered blade 112 increases, causing the centrifugal force of the centrifugal ball 105 to increase synchronously. This centrifugal force is then controlled by the deflection action of the deflection rod 104. It is converted into mechanical displacement, realizing real-time perception of wind force changes and linkage with the adjustment of the deflector. The response process is without the participation of electronic components, with a simple structure and strong anti-interference ability. At the same time, the deflection rod 104 drives the connecting seat 106 to move through the connecting rod 107, and the traction rope 125 stretches and drives the first deflector 51 and the second deflector 52 to deflect, so that the angle between the two plates increases with the increase of wind force, forming a windproof area that matches the wind pressure. This avoids excessive obstruction in weak winds, which affects the spraying efficiency, and ensures sufficient wind barrier strength in strong winds, keeping the paint mist flow stable.

[0042] The opening / closing component 12 includes a support rod 121 disposed at the top of the positioning rod 5. The support rod 121 and the positioning rod 5 are respectively provided with a connecting groove 122 and a guide groove 123, and the connecting groove 122 and the guide groove 123 are interconnected. Rotating blocks 124 are rotatably disposed at both ends of the connecting groove 122. A limiting block 126 is disposed inside the rotating chamber 73. A traction rope 125 is disposed on the sliding plate 102. The traction rope 125 passes through the limiting block 126 inside the rotating chamber 73, the guide groove 123 inside the positioning rod 5, and the connecting groove 122 inside the support rod 121 in sequence, and is led out after being guided by the rotating blocks 124 at both ends of the connecting groove 122. The led-out traction rope 125 is connected to the first guide plate 51 and the second guide plate 52 respectively, and the traction rope 125 passes through the side wall of the rotating chamber 73 and is movably connected to the side wall of the rotating chamber 73.

[0043] When the connecting seat 106 moves, it causes the traction rope 125 to stretch. During the stretching process, the traction rope 125 further causes the first guide plate 51 and the second guide plate 52 to deflect, making the included angle between the first guide plate 51 and the second guide plate 52 larger. At the same time, the design of the rotating block 124 makes the stretching of the traction rope 125 smoother. When the wind force changes, the included angle of the guide plates is dynamically adjusted to balance the lateral wind load. When the wind force increases, the included angle is widened to enhance the impact resistance. When the wind force decreases, the included angle is narrowed to maintain the airflow focus. Under strong winds, the included angle is widened to convert lateral wind energy into harmless longitudinal kinetic energy. Under weak winds, the included angle is narrowed to reduce energy loss and maintain airflow stability, achieving a precise match between wind resistance intensity and wind force. This makes it more reliable in dealing with sudden gusts or continuous strong winds. Moreover, widening the included angle when the wind force increases can reduce the risk of paint scattering, thereby reducing the ineffective diffusion of paint and simultaneously reducing secondary pollution to the surrounding environment.

[0044] Example 2: Please refer to Figures 9-10 The present invention provides a technical solution: a spacing adjustment component 13 is provided on the movable base 3, and the spacing adjustment component 13 is used to adjust the spacing between the spray gun 4 and the wall surface to be sprayed according to the external wind force.

[0045] The spacing adjustment component 13 includes multiple telescopic rods 131 disposed on the outside of the rotating chamber 73. A movable plate 132 is disposed on each telescopic rod 131. A movable lead screw 133 is disposed on the side of the movable plate 132 facing the rotating chamber 73. An adjusting rod 134 is rotatably disposed on the rotating chamber 73. The adjusting rod 134 is threadedly connected to the movable lead screw 133. A spring box 135 is disposed on the rotating chamber 73. The spring box 135 is rotatably connected to the adjusting rod 134. A spring spring 136 is disposed inside the spring box 135. One end of the spring spring 136 is connected to the adjusting rod 134. A winding wheel 137 is disposed on the adjusting rod 134. A second limit block 138 is disposed inside the rotating chamber 73. A pull rope 139 is disposed on the winding wheel 137. The pull rope 139 passes through the side wall of the rotating chamber 73 and the second limit block 138 and is connected to the sliding plate 102. The pull rope 139 is movably connected to the rotating chamber 73.

[0046] When the wind increases, the sliding plate 102 rises, which in turn stretches the pull rope 139, causing the winding shaft to rotate. This, in turn, causes the adjusting rod 134 to rotate, which in turn pushes the moving screw 133 to move. Finally, the moving plate 132, connected to the moving screw 133, moves the spray gun 4 closer to the wall. When the wind decreases, the spring 136 releases its elasticity, which can reset the spray gun 4. When the wind increases, the distance between the spray gun 4 and the wall is shortened, reducing the wind interference on the paint atomization trajectory. When the wind decreases, the standard working distance is restored through the elastic reset mechanism. The entire process is controlled by mechanical transmission, requiring no external energy input, and has the advantages of rapid response and zero energy consumption.
