Description

Technical Field

[0001] The present invention relates to the technical field of fire retardant coating spraying equipment, and in particular to an automated climbing spraying device for fire retardant coating. Background Art

[0002] With its core advantages of high strength, light weight and easy construction, steel structures have demonstrated wide applicability in the field of modern engineering. In the field of construction, they can be flexibly adapted to various types of high-rise buildings, large-span public buildings and multi-story industrial buildings. In addition, the modular construction characteristics and recyclable advantages of steel structures are in line with the concepts of green building and sustainable development. They also demonstrate rapid deployment capabilities in scenarios such as emergency construction and post-disaster reconstruction. From urban landmarks to people's livelihood projects, steel structures, with their diverse technical adaptability, continue to promote the innovation and development of engineering construction in various fields.

[0003] I-beams in steel structures are I-shaped cross-sections, consisting of upper and lower flanges and a web. They offer excellent compressive and flexural properties and are widely used in engineering fields such as construction and bridges. However, I-beams have poor fire resistance and typically require the application of fire-retardant coatings.

[0004] The currently commonly used manual spraying method has significant defects: the operator needs to hold the spraying equipment and move it on the surface of the I-beam. Since manual operation control makes it difficult to accurately grasp the paint flow, spray range and movement speed, it often leads to uneven coating thickness, spray leakage or local over-thickness. At the same time, the spray range of the spraying equipment is often larger than the narrow surface of the I-beam, resulting in a large amount of paint waste. In addition, for high-altitude work scenes, operators need to use a lifting platform vehicle for mobile spraying, and the position of the vehicle needs to be frequently adjusted during the spraying process, which not only affects the continuity of the spraying operation, but also significantly reduces the overall construction efficiency. In response to the above problems, there is an urgent need for an intelligent spraying equipment with automatic climbing function to solve the problems of unstable quality and low efficiency of manual spraying, so as to achieve high-precision and high-efficiency automated spraying of fire retardant coatings. Summary of the Invention

[0005] The present invention aims to provide an automated climbing spraying device for fire retardant coatings, which can avoid the problems of unstable quality and low efficiency of manual spraying, thereby achieving high-precision and high-efficiency automated spraying of fire retardant coatings.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] 1) An automated climbing spraying device for fire retardant coating, comprising a sliding vehicle body that can move along the length of an I-beam and be attached to the surface of the I-beam, and a microprocessor; a spraying structure for spraying coating onto the surface of the I-beam is connected to the side of the sliding vehicle body; the sliding vehicle body comprises an elongated and retractable top plate; a first side plate and a second side plate are respectively provided at the ends of the top plate, and a first sliding structure and a second sliding structure are respectively provided on the inner sides of the first and second side plates; the first and second sliding structures are respectively provided in a symmetrical arrangement, and the first and second sliding structures can be respectively embedded in the I-beam and slide along its length;

[0008] An adsorption component is provided in the top plate, and the adsorption component is used to suck the gas between the sliding vehicle body and the surface of the I-beam. A material storage box is provided above the top plate, and the material storage box can slide along the upper surface of the top plate. A discharge port is provided on the side of the material storage box, and the discharge port is close to the bottom of the material storage box. A flow meter is provided in the discharge port, and the discharge port is connected to the spraying structure. The spraying structure, adsorption component, sliding structure and flow meter are electrically connected to the microprocessor respectively.

[0009] In the present invention, the I-beam is composed of horizontally arranged upper and lower flanges, and a vertically connected web. The first and second sliding structures utilize an embedded design, precisely snapping into the gaps formed by the upper and lower flanges and web, respectively, ensuring the stability of the first and second sliding structures as they move along the length of the I-beam. The movement of the first and second sliding structures drives the sliding carriage, and their symmetrical arrangement ensures smooth movement of the sliding carriage on the I-beam.

[0010] The spray mechanism is attached to the side of the sliding vehicle, and the uniform movement of the sliding vehicle drives the spray mechanism with it. This setup ensures a uniform and stable movement speed during the spraying process, avoiding the uneven spray thickness caused by inconsistent movement speeds during manual operation. Furthermore, this setup enables continuous spraying without the need for a lift truck, thereby improving the efficiency and quality of the spraying process while reducing costs.

[0011] The skid structure includes a roof panel, above which is located a storage tank for fire retardant paint. This tank, connected to the spraying mechanism, enables continuous and stable paint delivery, ensuring a continuous spraying operation. The tank slides along the top panel's upper surface, allowing it to move with the roof panel as it expands or contracts. This ensures the tank's flexibility and stability, and consequently, the continuity and stability of the spraying operation.

[0012] The top plate is equipped with a suction assembly. This assembly draws air between the skid and the I-beam, creating a vacuum between them. This allows the skid to adhere to the surface, preventing the skid from falling off during the spraying process. This arrangement also significantly improves the skid's stability during movement, preventing any impact on the spraying process caused by the skid's swaying and ensuring uniform spraying.

[0013] A storage tank, containing fire retardant paint, is mounted above the skid body. A discharge port is located near the bottom of the tank. Because the spray mechanism is located on the side of the skid body, it is lower than the storage tank, creating a height difference. Gravity forces the fire retardant paint to flow from the discharge port into the spray mechanism, ensuring a continuous supply of paint and a continuous spraying operation.

[0014] During the fire retardant coating spraying process, the first and second sliding structures are first deployed to the sides, thereby driving the first and second side panels to move to the sides, thereby extending the top panel. The deployed sliding body is then placed on the I-beam, with the top panel positioned on the surface of the upper (or lower) flange of the I-beam. The first and second sliding structures are then respectively embedded in the corresponding gaps formed by the upper and lower flanges and the web of the I-beam.

[0015] The suction assembly is then manually activated, sucking the air between the sliding carriage and the I-beam surface. This air is then transferred to the storage tank, which increases the pressure. This pressure pushes the fire retardant coating inside the tank into the spray mechanism through the discharge port. A flowmeter inside the discharge port monitors the coating flow in real time and transmits the measured flow rate to a microprocessor. The flowmeter is a LUGB-MIK vortex flowmeter.

[0016] The microprocessor has a pre-set workflow: if it stops receiving continuous flow rate signals from the flow meter, it determines that the spray mechanism is fully filled with spray paint. It then activates the spray mechanism to apply fire retardant paint to the I-beam surface. Simultaneously, the microprocessor activates the first and second sliding mechanisms, driving the sliding carriage to smoothly move along the I-beam's axis. As the sliding carriage moves, the spray mechanism follows suit, continuously and evenly applying fire retardant paint to the I-beam surface, achieving a high-quality coating.

[0017] The microprocessor precisely controls the first and second sliding structures, the suction assembly, and the spraying mechanism, ensuring coordinated operation. This allows for intelligent climbing and spraying during the spraying process. This setup effectively avoids the inconsistent quality and inefficiency associated with manual spraying, enabling high-precision, high-efficiency automated spraying of fire retardant coatings.

[0018] 2) The automatic climbing spraying device for fire retardant coating according to 1), wherein:

[0019] The top plate includes a first horizontal plate and a second horizontal plate which are long and parallel, a retractable connecting plate is provided between the first horizontal plate and the second horizontal plate, the first side plate is located at the end of the first horizontal plate, a first fixed plate is provided horizontally at the bottom of the first side plate, the second side plate is located at the end of the second horizontal plate, a second fixed plate is provided horizontally at the bottom of the second side plate, the first sliding structure is located below the first horizontal plate, the second sliding structure is located below the second horizontal plate, the adsorption assembly is located in the second horizontal plate, and the sides of the first horizontal plate, the second horizontal plate, the first fixed plate and the second fixed plate are commonly connected with a connecting component for connecting the spraying structure.

[0020] In the present invention, the first transverse plate and the second transverse plate are connected via a retractable connecting plate, which can be retracted and adjusted according to demand, thereby increasing the flexibility and versatility of the sliding vehicle body and enabling it to adapt to I-beams of different widths.

[0021] The operator adjusts the extension length of the connecting plate based on the actual width of the I-beam. When the connecting plate extends, it drives the first and second transverse plates to move outward. Because the first and second side plates are fixed to their respective ends, they also expand outward. As the first and second side plates expand, the first and second sliding structures also move outward.

[0022] Once the connecting plate has been extended to the desired length, the operator moves the skid body over the I-beam and aligns the first and second sliding structures with the gaps between the upper and lower flanges and the web of the I-beam. The connecting plate is then retracted. During this retraction process, the first and second sliding structures gradually engage with the gaps between the upper and lower flanges and the web of the I-beam, respectively. At this point, the skid body forms a stable connection to the I-beam through the first and second sliding structures.

[0023] The suction assembly, located within the second horizontal plate, draws air from the space between the skid and the I-beam, generating suction. This force secures the skid to the I-beam, effectively preventing it from shaking or falling off. Simultaneously, the suction assembly continuously delivers the drawn air into the storage tank. As the gas continues to flow in, the pressure within the tank increases accordingly.

[0024] This pressurization creates a pressure-driven effect on the fire-retardant coating within the storage tank, pushing it through the discharge port and into the spraying mechanism. This ensures a stable and continuous flow of the coating into the spraying mechanism, ensuring the continuity of the spraying operation. Compared to gravity-fed systems, this setup avoids the drop in static pressure caused by a drop in the liquid level within the storage tank, eliminating the risk of a gradual decrease in flow and uneven spraying, and ensuring reliable operation of the spraying process. Furthermore, by increasing the pressure by feeding the sucked gas into the storage tank through the adsorption component, the cost of equipment usage can be reduced compared to traditional mechanical pumping.

[0025] The sides of the first horizontal plate, the second horizontal plate, the first fixed plate and the second fixed plate are commonly connected with connecting parts for connecting the spraying structure, which firmly connect the spraying structure to the sliding vehicle body, thereby ensuring that the spraying structure can move smoothly with the sliding vehicle body, thereby ensuring the continuity and uniformity of the spraying operation and effectively improving the spraying quality.

[0026] 3) The automatic climbing spraying device for fire retardant coating according to 2), wherein:

[0027] The first and second transverse plates are provided with a first embedding groove and a second embedding groove on opposing surfaces, respectively. The first embedding groove, the second embedding groove and the central axis of the connecting plate overlap. The two end portions of the connecting plate are respectively embedded in the first and second embedding grooves, and the two end portions of the connecting plate can slide along the length directions of the first and second embedding grooves, respectively. The two end surfaces of the connecting plate are provided with a first spring and a second spring, respectively. The end portion of the first spring is fixedly connected to the bottom of the first embedding groove, and the end portion of the second spring is fixedly connected to the bottom of the second embedding groove.

[0028] In the present invention, the first and second mounting grooves are respectively provided on opposing surfaces of the first and second transverse plates, and are used to engage the ends of the connecting plate, providing space and limiting the extension and contraction of the connecting plate. When the width of the sliding vehicle body needs to be adjusted to accommodate I-beams of varying widths, the operator applies opposite pulling forces to the first and second transverse plates, thereby stretching the first and second springs. As the first and second springs extend, the ends of the connecting plate slide out along the first and second mounting grooves, respectively, increasing the length of the connecting plate between the first and second mounting grooves, thereby increasing the spacing between the first and second transverse plates, thereby achieving width adjustment of the sliding vehicle, enabling it to accommodate I-beams of varying widths.

[0029] When the connecting plate is extended to the appropriate length, the operator moves the sliding car body above the I-beam and aligns the first sliding structure and the second sliding structure with the gap between the upper flange plate, the lower flange plate and the web plate of the I-beam. The operator then stops applying tension to the first cross plate and the second cross plate.

[0030] When the operator stops applying tension to the first and second transverse plates, the elastic restoring forces of the first and second springs drive the ends of the connecting plates back along the first and second mounting slots, respectively, bringing the first and second transverse plates closer together. This movement of the first and second transverse plates is transmitted via the first and second side plates to the first and second fixed plates, ultimately allowing the first and second sliding structures to precisely fit into the gaps formed between the upper and lower flanges and the web of the I-beam. This arrangement automatically completes the retraction process under the influence of the spring forces of the first and second springs, ensuring a secure connection between the sliding carriage and the I-beam, effectively preventing displacement or disengagement during operation, and enabling fast and reliable automatic installation.

[0031] 4) The automatic climbing spraying device for fire retardant coating according to 3), wherein:

[0032] The opposite inner walls of the first mounting groove are respectively provided with a first sliding groove extending along the length direction thereof, and the sides of the connecting plate facing the first sliding groove are respectively provided with a first slider, and the first slider can slide along the first sliding groove corresponding thereto. The opposite inner walls of the second mounting groove are respectively provided with a second sliding groove extending along the length direction thereof, and the sides of the connecting plate facing the second sliding groove are respectively provided with a second slider, and the second slider can slide along the second sliding groove corresponding thereto.

[0033] In the present invention, the first and second chutes are respectively defined on opposing inner walls of the first and second mounting grooves, extending along the length of the mounting grooves. A first slider and a second slider are respectively disposed on the side of the connecting plate facing the first and second chutes. The first slider can slide along its corresponding first chute, and the second slider can slide along its corresponding second chute, allowing the ends of the connecting plate to slide smoothly within the first and second chutes, respectively. The first and second chutes provide precise guide paths for the sliding of the connecting plate, preventing lateral or diagonal deviation of the connecting plate, thereby improving the accuracy and stability of the connecting plate's telescopic movement.

[0034] 5) The automatic climbing spraying device for fire retardant coating according to 2), wherein:

[0035] The first sliding structure includes two first sliding assemblies symmetrically arranged about the central axis of the first transverse plate, the first sliding assembly including a first roller, the first roller being located between the first transverse plate and the first fixed plate, the axis of the first roller being parallel to the first side plate, a first roller being coaxially provided inside the first roller, the top of the first roller being rotatably connected to the first transverse plate, the bottom of the first roller being rotatably connected to the first fixed plate, the top of one of the first rollers being connected to a first micro motor, the first micro motor being located on the bottom surface of the first transverse plate;

[0036] The second sliding structure includes two second sliding components symmetrically arranged about the central axis of the second transverse plate, the second sliding component includes a second roller, the second roller is located between the second transverse plate and the second fixed plate, the axis of the second roller is parallel to the second side plate, a second roller is coaxially provided inside the second roller, the top of the second roller is rotatably connected to the second transverse plate, and the bottom of the second roller is rotatably connected to the second fixed plate, a second micro motor is connected to the top surface of one of the second rollers, the second micro motor is located on the bottom surface of the second transverse plate, the first micro motor corresponds to the second micro motor, and the first micro motor and the second micro motor are respectively electrically connected to a microprocessor.

[0037] In the present invention, the first and second micromotors are model 260 micromotors. When the first and second sliding structures have respectively embedded themselves into the gaps between the corresponding upper and lower flanges and webs of the I-beam, and the spraying structure has completed injection, the microprocessor simultaneously commands the first and second micromotors to start.

[0038] When the first micromotor is activated, it drives the first roller connected to it to rotate, thereby driving the first roller connected to it to roll along the axis of the I-beam. Similarly, when the second micromotor is activated, it drives the second roller connected to it to rotate, thereby driving the second roller connected to it to roll along the axis of the I-beam. The rotation of the first and second rollers propels the sliding body. As the sliding body moves, the other first and second rollers also roll, ensuring smooth and continuous movement of the entire sliding body.

[0039] 6) The automatic climbing spraying device for fire retardant coating according to 3), wherein:

[0040] The adsorption component includes a miniature vacuum diaphragm pump, a placement chamber is opened in the second horizontal plate, the miniature vacuum diaphragm pump is located in the placement chamber, the miniature vacuum diaphragm pump has an exhaust port and an exhaust port, a gas channel is provided in the connecting plate that runs through the connecting plate in the direction of its thickness, the gas channel is provided with a gas inlet and a gas outlet, the gas inlet is located on the lower surface of the connecting plate, the gas outlet is located on the upper surface of the connecting plate, the exhaust port is connected to an exhaust pipe, the exhaust pipe passes through the second horizontal plate and is connected to the gas outlet, the exhaust port is connected to an exhaust pipe, the exhaust pipe passes through the second horizontal plate and is connected to the storage box, and the miniature vacuum diaphragm pump is electrically connected to the microprocessor.

[0041] In the present invention, the models of the micro vacuum diaphragm pump are: TRN large-flow micro air pump, corrosion-resistant high vacuum diaphragm pump. A placement chamber is provided in the second horizontal plate to provide installation space for the micro vacuum diaphragm pump. A gas channel is provided in the connecting plate that runs through the connecting plate in the direction of its thickness. The gas inlet of the gas channel is located on the lower surface of the connecting plate, and the gas outlet is located on the upper surface of the connecting plate. The gas outlet is connected to the exhaust port of the micro vacuum diaphragm pump through the exhaust pipe, thereby forming a complete gas passage. This setting method enables the gas between the sliding car body and the I-beam to be effectively sucked out, thereby forming a stable negative pressure environment. Through the action of negative pressure, the sliding car body can be firmly adsorbed on the surface of the I-beam, thereby ensuring stability and safety during operation.

[0042] The exhaust port of the micro vacuum diaphragm pump is connected to the storage tank via an exhaust pipe. When the micro vacuum diaphragm pump is operating, it continuously extracts air from between the sliding car body and the I-beam through the exhaust pipe. This air enters the exhaust pipe through the exhaust port and is ultimately transported into the storage tank. As the gas continues to fill, the internal pressure of the storage tank gradually increases, providing power for the delivery of the fire retardant coating, ensuring that the fire retardant coating can flow steadily through the discharge port to the spray structure.

[0043] 7) The automatic climbing spraying device for fire retardant coating according to 2), wherein:

[0044] The upper surface of the first transverse plate is provided with two first slides extending and parallel to the length thereof, and the bottom of the storage box is provided with two first moving blocks corresponding one to one with the first slides, and the first moving blocks can move along the first slides corresponding thereto, and the upper surface of the second transverse plate is provided with two second slides extending and parallel to the length thereof, and the bottom of the storage box is provided with two second moving blocks corresponding one to one with the second slides, and the second moving blocks can move along the second slides corresponding thereto.

[0045] In the present invention, when the width of the sliding vehicle body needs to be adjusted, the operator adjusts the distance between the first transverse plate and the second transverse plate. During the process of adjusting the distance between the first transverse plate and the second transverse plate, the first transverse plate and the second transverse plate produce corresponding displacements. At this time, the two first slides on the upper surface of the first transverse plate and the corresponding first moving blocks produce relative sliding, while the two second slides on the upper surface of the second transverse plate and the corresponding second moving blocks produce relative sliding. This arrangement can ensure that during the process of adjusting the distance between the first transverse plate and the second transverse plate, the material storage box can follow the movement of the first transverse plate and the second transverse plate and produce relative displacement, thereby ensuring the smoothness of the adjustment process and the stability of the material storage box.

[0046] 8) The automatic climbing spraying device for fire retardant coating according to 3), wherein:

[0047] The spraying structure includes a metal bellows that can be bent along the outer contour of the I-beam and can surround the surface of the I-beam, the two ends of the metal bellows are closed, and the two ends of the metal bellows are connected by a snap buckle, the metal bellows is provided with a corrugated straight section and a turning section, all the corrugated straight sections are outer-circuited with a rigid metal tube, the corrugated straight sections are evenly distributed along their axial direction with several first nozzles facing the surface of the I-beam, a valve is provided in the first nozzle, the rigid metal tube is provided with a second nozzle corresponding to the first nozzle one by one, the first nozzle is provided with an atomizing nozzle extending to the corresponding second nozzle, the atomizing nozzle has an atomizing outlet, the atomizing outlet is connected to the corresponding second nozzle, the metal bellows is connected to the discharge port of the storage box toward the side wall of the storage box, the connecting component is detachably connected to the corresponding rigid metal tube, and all valves are electrically connected to the microprocessor.

[0048] In the present invention, the metal bellows is provided with straight and curved sections, allowing it to flexibly adapt to the contours of I-beams of varying sizes, thereby enhancing the flexibility and versatility of the spray coating structure. The metal bellows can bend along the outer contour of the I-beam and wrap around the surface of the I-beam at equal intervals, ensuring that the sprayed fire retardant coating evenly covers the entire outer surface of the I-beam, thereby preventing uneven spraying.

[0049] The metal bellows is sealed at both ends and connected by a clip, making it easy to install. To install the metal bellows, the operator first releases the clip lock; then, unfolds the metal bellows and wraps it around the surface of the I-beam; finally, closes the clip to secure the connection, completing the installation.

[0050] A rigid metal tube is placed around the straight section of the corrugated steel, enhancing its structural stability. This tube provides additional support, ensuring it maintains its fixed shape during the spraying process and resists deformation due to external impacts or internal pressure fluctuations. By preventing deformation of the straight section, the tube ensures a precise spray path, allowing the fire retardant coating to be applied evenly and continuously to the I-beam surface, thereby improving spray quality.

[0051] The corrugated straight section has several primary nozzles evenly distributed along its axial direction, and the rigid metal tube is equipped with secondary nozzles corresponding to each of the first nozzles. Atomizing nozzles are installed within the first nozzles, extending toward the corresponding secondary nozzles, with the atomizing outlets of the atomizing nozzles communicating with the corresponding secondary nozzles. The secondary nozzles on the rigid metal tube provide a stable mounting position for the atomizing nozzles, ensuring that they can accurately spray the fire retardant coating through the atomizing outlets.

[0052] Among them, the first nozzles are evenly distributed along the axial direction of the straight section of the corrugation, so that the first nozzles match the contour of the I-beam, thereby ensuring that the sprayed paint can evenly cover the entire surface of the I-beam. Traditional spraying equipment has a wide spray range of a single nozzle, which easily exceeds the narrow upper flange plate, lower flange plate and web plate of the I-beam, resulting in waste of fire retardant paint and uneven coverage. The first nozzles evenly distributed along the axial direction of the straight section of the corrugation can accurately control the spray angle and range, so that the sprayed paint acts directly on the target surface, avoiding scattering and overspray. At the same time, the synergistic effect of several first nozzles can cover the entire surface of the I-beam, reducing the problems of missed spraying or uneven coating thickness, thereby improving spraying efficiency and coating quality.

[0053] The metal bellows, facing the side wall of the storage tank, is connected to the tank's discharge port, ensuring smooth transfer of coating material from the tank into the metal bellows. When the metal bellows is fully filled, the microprocessor activates the first and second sliding mechanisms, driving the sliding vehicle body along the I-beam. This then opens the valves in all the first nozzles, allowing the fire-retardant coating in the metal bellows to be sprayed from the atomizing nozzles onto the I-beam surface.

[0054] 9) The automatic climbing spraying device for fire retardant coating according to 8), wherein:

[0055] The corrugated straight section of the metal bellows is provided with a first feed port toward the side wall of the storage box, and the rigid metal tube is provided with a second feed port corresponding to the first feed port. The first feed port is connected to a feed pipe, and the end of the feed pipe passes through the second feed port and is connected to the discharge port of the storage box.

[0056] In this invention, when an operator manually activates the micro-vacuum diaphragm pump, it draws air from between the sliding carriage and the I-beam surface and transfers it into the storage tank, increasing the pressure within. Driven by this pressure, the fire retardant coating within the tank is forced out of the discharge port and then transported through the feed pipe into the metal bellows, completing the automatic supply of the fire retardant coating.

[0057] 10) The automatic climbing spraying device for fire retardant coating according to 8), wherein:

[0058] The connecting components include several connecting rods, which are respectively located on the sides of the first transverse plate, the second transverse plate, the first fixed plate and the second fixed plate and extend toward the spraying structure. All connecting rods are parallel to each other, and the ends of all connecting rods are detachably connected to corresponding rigid metal tubes.

[0059] In this invention, the connecting components include several connecting rods, which securely connect the first and second transverse plates, the first and second fixed plates, and the rigid metal tubes, forming a rigid, integrated structure between the sliding vehicle body and the spray coating structure. This arrangement effectively reduces the swaying of the spray coating structure during movement, improving stability and ensuring uniform application of the fire retardant coating to the I-beam surface. Furthermore, the ends of the connecting rods are detachably connected to the rigid metal tubes, facilitating routine maintenance and adjustments and enhancing the flexibility and practicality of the spray coating structure.

[0060] Compared with the prior art, the present invention also has the following technical effects:

[0061] In the present invention, the movement of the first sliding structure and the second sliding structure can drive the sliding vehicle body to move accordingly. The spraying structure is connected to the side of the sliding vehicle body, and the uniform movement of the sliding vehicle body can drive the spraying structure to move accordingly. Compared with the existing technology, the present invention ensures that the movement speed of the spraying structure is uniform and stable during the spraying process, avoiding the problem of uneven spray thickness caused by inconsistent movement speed during manual operation. In addition, this setting method can realize continuous spraying operation without relying on a lifting platform vehicle, thereby improving the efficiency and quality of the spraying operation while reducing the spraying cost.

[0062] Secondly, the suction assembly draws air between the sliding body and the I-beam surface, ensuring it remains firmly and securely attached to the surface, preventing the sliding body from falling off during the spraying process. The suction assembly pumps the suctioned air into the storage tank to increase pressure, providing power for the fire retardant coating, ensuring a steady flow of the coating through the discharge port to the spraying mechanism. This reduces equipment costs compared to traditional mechanical pumping. Precise microprocessor control of the first and second sliding mechanisms, the suction assembly, and the spraying mechanism ensures coordinated operation, enabling intelligent climbing and spraying during the spraying process.

[0070] For example, see Figure 1As shown, the automatic climbing spraying device for fire retardant coating in this embodiment includes a sliding body and a microprocessor that can move along the length direction of the I-beam and be adsorbed on the surface of the I-beam. The side of the sliding body is connected to a spraying structure for spraying coating on the surface of the I-beam. The sliding body includes a long and retractable top plate, and the ends of the top plate are respectively provided with a first side plate 1 and a second side plate 2 that are vertically arranged. The inner sides of the first side plate 1 and the second side plate 2 are respectively provided with a first sliding structure and a second sliding structure. The first sliding structure and the second sliding structure are respectively arranged symmetrically. The first sliding structure and the second sliding structure can be respectively embedded in the I-beam and slide along its length direction.

[0071] Among them, an adsorption component is provided in the top plate, which is used to suck the gas between the sliding vehicle body and the surface of the I-beam. A storage box 3 is provided above the top plate, and the storage box 3 can slide along the upper surface of the top plate. A discharge port is provided on the side of the storage box 3, and the discharge port is close to the bottom of the storage box 3. A flow meter is provided in the discharge port, and the discharge port is connected to the spraying structure. The spraying structure, adsorption component, sliding structure and flow meter are electrically connected to the microprocessor respectively.

[0072] In this embodiment, the I-beam is composed of horizontally arranged upper and lower flanges, and a vertically connected web. The first and second sliding structures utilize an embedded design, precisely snapping into the gaps formed by the upper and lower flanges and web, respectively, ensuring the stability of the first and second sliding structures as they move along the length of the I-beam. The movement of the first and second sliding structures drives the sliding carriage, and their symmetrical arrangement ensures smooth movement of the sliding carriage on the I-beam.

[0073] The spray mechanism is attached to the side of the sliding vehicle, and the uniform movement of the sliding vehicle drives the spray mechanism with it. This setup ensures a uniform and stable movement speed during the spraying process, avoiding the uneven spray thickness caused by inconsistent movement speeds during manual operation. Furthermore, this setup enables continuous spraying without the need for a lift truck, thereby improving the efficiency and quality of the spraying process while reducing costs.

[0074] The skid structure includes a roof panel, above which is located a storage tank 3 for storing fire-retardant paint. This tank, connected to the spraying mechanism, enables continuous and stable paint delivery, ensuring a continuous spraying operation. The storage tank 3 slides along the top panel's upper surface, allowing it to move with the roof panel as it expands or contracts. This ensures the flexibility and stability of the storage tank 3, and consequently, the continuity and stability of the spraying operation.

[0075] A suction assembly is installed within the top plate. This assembly draws air between the skid and the I-beam surface, ensuring the skid adheres tightly and securely to the surface, preventing the skid from falling off during the spraying process. This arrangement also significantly improves the skid's stability during movement, preventing any impact on the spraying process caused by the skid's swaying and ensuring uniform spraying.

[0076] A storage tank 3, containing fire retardant paint, is mounted above the skid body. A discharge port is located near the bottom of the tank 3. Because the spraying mechanism is located on the side of the skid body, it is lower than the storage tank 3, creating a height difference. Gravity forces the fire retardant paint to flow from the discharge port and into the spraying mechanism, ensuring a continuous supply of paint and a continuous spraying operation.

[0077] During the fire retardant coating spraying process, the first and second sliding structures are first deployed to the sides, thereby driving the first and second side panels 1 and 2 to move to the sides, thereby extending the top panel. The deployed sliding body is then placed on the I-beam, with the top panel positioned on the upper (or lower) flange of the I-beam. The first and second sliding structures are then respectively embedded in the corresponding gaps formed by the upper and lower flanges and the web of the I-beam.

[0078] The suction assembly is then manually activated, sucking the air between the sliding vehicle body and the I-beam surface. This air is then transferred to the storage tank, which in turn increases the pressure inside. This pressure pushes the fire retardant coating inside the storage tank 3 into the spray mechanism through the discharge port. A flowmeter inside the discharge port monitors the coating flow in real time and transmits the measured flow rate to the microprocessor. The flowmeter is a LUGB-MIK vortex flowmeter.

[0079] The microprocessor has a pre-set workflow: if it stops receiving continuous flow rate signals from the flow meter, it determines that the spray mechanism is fully filled with spray paint. It then activates the spray mechanism to apply fire retardant paint to the I-beam surface. Simultaneously, the microprocessor activates the first and second sliding mechanisms, driving the sliding carriage to smoothly move along the I-beam's axis. As the sliding carriage moves, the spray mechanism follows suit, continuously and evenly applying fire retardant paint to the I-beam surface, achieving a high-quality coating.

[0080] The top plate includes a first horizontal plate 4 and a second horizontal plate 5 which are long and parallel. A retractable connecting plate 6 is provided between the first horizontal plate 4 and the second horizontal plate 5. The first side plate 1 is located at the end of the first horizontal plate 4. A first fixed plate 7 is provided horizontally at the bottom of the first side plate 1. The second side plate 2 is located at the end of the second horizontal plate 5. A second fixed plate 8 is provided horizontally at the bottom of the second side plate 2. The first sliding structure is located below the first horizontal plate 4. The second sliding structure is located below the second horizontal plate 5. The adsorption assembly is located in the second horizontal plate 5. The sides of the first horizontal plate 4, the second horizontal plate 5, the first fixed plate 7 and the second fixed plate 8 are commonly connected with a connecting component for connecting the spraying structure.

[0081] In this embodiment, the first transverse plate 4 and the second transverse plate 5 are connected by a retractable connecting plate 6, which can be retracted and adjusted according to needs, thereby increasing the flexibility and versatility of the sliding vehicle body, enabling it to adapt to I-beams of different widths.

[0082] The operator adjusts the extension length of the connecting plate 6 based on the actual width of the I-beam. When the connecting plate 6 extends, it drives the first and second transverse plates 4 and 5 to move outward. Because the first and second side plates 1 and 2 are fixed to the ends of the first and second transverse plates 4 and 5, respectively, they also expand outward. As the first and second side plates 1 and 2 expand, the first and second sliding structures also move outward.

[0083] After the connecting plate 6 is extended to the appropriate length, the operator moves the sliding body over the I-beam and aligns the first and second sliding structures with the gaps between the upper and lower flanges and the web of the I-beam. The connecting plate 6 then retracts. During the retraction process, the first and second sliding structures gradually embed themselves into the gaps between the upper and lower flanges and the web of the I-beam, respectively. At this point, the sliding body forms a stable connection to the I-beam through the first and second sliding structures.

[0084] The suction assembly, located within the second transverse plate 5, draws air from between the skid body and the I-beam surface, generating a suction force. This force secures the skid body to the I-beam surface, effectively preventing it from swaying or falling off. Simultaneously, the suction assembly continuously delivers the drawn air into the storage tank. As the gas continues to flow in, the pressure within the tank increases accordingly.

[0085] This pressurization effect will form a pressure drive on the fire retardant coating in the storage tank 3, thereby pushing the fire retardant coating to flow into the spraying structure through the discharge port, thereby ensuring that the fire retardant coating can flow into the spraying structure stably and continuously, thereby ensuring the continuous progress of the spraying operation. Compared with the method of relying on gravity feeding, this setting method can avoid the problem of static pressure reduction caused by the drop in the liquid level in the storage tank, thereby eliminating the risk of gradually decreasing flow rate and uneven spraying, and ensuring the reliable operation of the spraying process. In addition, the suction component is used to input the sucked gas into the storage barrel 3 to increase the air pressure, which can reduce the cost of equipment use compared to traditional mechanical pumping.

[0086] The sides of the first transverse plate 4, the second transverse plate 5, the first fixed plate 7 and the second fixed plate 8 are commonly connected with connecting parts for connecting the spraying structure, which firmly connect the spraying structure to the sliding vehicle body, thereby ensuring that the spraying structure can move smoothly with the sliding vehicle body, thereby ensuring the continuity and uniformity of the spraying operation, and effectively improving the spraying quality.

[0087] See also Figure 2 As shown, the opposing surfaces of the first transverse plate 4 and the second transverse plate 5 are respectively provided with a first embedding groove 9 and a second embedding groove 10, the central axis of the first embedding groove 9, the second embedding groove 10 and the connecting plate 6 overlap, and the two end portions of the connecting plate 6 are respectively embedded in the first embedding groove 9 and the second embedding groove 10, and the two end portions of the connecting plate 6 can slide along the length direction of the first embedding groove 9 and the second embedding groove 10, respectively. The two end surfaces of the connecting plate 6 are respectively provided with a first spring 11 and a second spring 12, and the end portion of the first spring 11 is fixedly connected to the bottom of the first embedding groove 9, and the end portion of the second spring 12 is fixedly connected to the bottom of the second embedding groove 10.

[0088] In this embodiment, the first and second mounting grooves 9 and 10 are respectively provided on opposite surfaces of the first and second transverse plates 4 and 5, and are used to fit into the ends of the connecting plate 6, providing space and a limiting function for the expansion and contraction of the connecting plate 6. When the width of the sliding vehicle body needs to be adjusted to accommodate I-beams of different widths, the operator applies pulling forces in opposite directions to the first and second transverse plates 4 and 5, thereby stretching the first and second springs 11 and 12. As the first and second springs 11 and 12 extend, the ends of the connecting plate 6 slide out along the first and second mounting grooves 9 and 10, respectively, thereby increasing the length of the connecting plate 6 between the first and second mounting grooves 9 and 10, thereby increasing the spacing between the first and second transverse plates 4 and 5, thereby achieving width adjustment of the sliding vehicle, enabling it to accommodate I-beams of different widths.

[0089] When the connecting plate 6 is extended to the appropriate length, the operator moves the sliding vehicle body above the I-beam and aligns the first sliding structure and the second sliding structure with the gap between the upper flange plate, the lower flange plate and the web plate of the I-beam. The operator then stops applying tension to the first cross plate 4 and the second cross plate 5.

[0090] When the operator stops applying tension to the first and second transverse plates 4, 5, the elastic restoring force of the first and second springs 11, 12 drives the two ends of the connecting plate 6 to retract along the first and second mounting grooves 9, 10, respectively, bringing the first and second transverse plates 4, 5 closer together. The movement of the first and second transverse plates 4, 5 closer together is transmitted to the first and second fixed plates 7, 8 via the first and second side plates 1, 2, ultimately allowing the first and second sliding structures to be precisely embedded in the gaps formed by the upper and lower flange plates and the web of the I-beam. This arrangement automatically completes the contraction process under the action of the spring force of the first and second springs 11, 12, ensuring a secure connection between the sliding vehicle body and the I-beam, effectively preventing displacement or falling off during operation, and thus achieving fast and reliable automatic installation.

[0091] The opposite inner walls of the first mounting groove 9 are respectively provided with first sliding grooves 13 extending along the length direction thereof, and the sides of the connecting plate 6 facing the first sliding grooves 13 are respectively provided with first sliders 14, and the first sliders 14 can slide along the corresponding first sliding grooves 13. The opposite inner walls of the second mounting groove 10 are respectively provided with second sliding grooves 15 extending along the length direction thereof, and the sides of the connecting plate 6 facing the second sliding grooves 15 are respectively provided with second sliders 16, and the second sliders 16 can slide along the corresponding second sliding grooves 15.

[0092] In this embodiment, the first and second chute grooves 13, 15 are respectively defined on opposing inner walls of the first and second mounting grooves 9, 10, extending along the length of the mounting grooves. A first slider 14 and a second slider 16 are respectively disposed on the sides of the connecting plate 6 facing the first and second chute grooves 13, 15. The first slider 14 can slide along its corresponding first chute 13, and the second slider 16 can slide along its corresponding second chute 15, allowing the ends of the connecting plate 6 to slide smoothly within the first and second chute grooves 13, 15, respectively. The first and second chute grooves 13, 15 provide precise guide paths for the sliding of the connecting plate 6, preventing lateral or diagonal deviation of the connecting plate 6, thereby improving the accuracy and stability of the connecting plate 6's telescopic movement.

[0093] See also Figure 5 As shown, the first sliding structure includes two first sliding components symmetrically arranged about the central axis of the first transverse plate 4, the first sliding component includes a first roller 17, the first roller 17 is located between the first transverse plate 4 and the first fixed plate 7, the axis of the first roller 17 is parallel to the first side plate 1, and a first roller 18 is coaxially provided inside the first roller 17. The top of the first roller 18 is rotatably connected to the first transverse plate 4, and the bottom of the first roller 18 is rotatably connected to the first fixed plate 7. A first micro motor 19 is connected to the top of one of the first rollers 18, and the first micro motor 19 is located on the bottom surface of the first transverse plate 4.

[0094] Secondly, the second sliding structure includes two second sliding components symmetrically arranged about the central axis of the second horizontal plate 5, and the second sliding component includes a second roller 20. The second roller 20 is located between the second horizontal plate 5 and the second fixed plate 8. The axis of the second roller 20 is parallel to the second side plate 2. A second roller 21 is coaxially provided inside the second roller 20. The top of the second roller 21 is rotatably connected to the second horizontal plate 5, and the bottom of the second roller 21 is rotatably connected to the second fixed plate 8. A second micro motor 22 is connected to the top surface of one of the second rollers 21. The second micro motor 22 is located on the bottom surface of the second horizontal plate 5. The first micro motor 19 corresponds to the second micro motor 22, and the first micro motor 19 and the second micro motor 22 are electrically connected to the microprocessor respectively.

[0095] In this embodiment, the first micromotor 19 and the second micromotor 22 are both model 260 micromotor. When the first and second sliding structures have respectively embedded themselves into the gaps between the upper and lower flanges and the web of the I-beam, and the spraying structure has completed injection, the microprocessor simultaneously commands the first and second micromotor 19, 22 to start.

[0096] When the first micromotor 19 is activated, it drives the first roller 18 connected to it to rotate, thereby driving the first roller 17 connected to it to roll along the axial direction of the I-beam. Similarly, when the second micromotor 22 is activated, it drives the second roller 21 connected to it to rotate, thereby driving the second roller 20 connected to it to roll along the axial direction of the I-beam. The rotation of the first roller 17 and the second roller 20 propels the sliding body. As the sliding body moves, the other first roller 17 and the second roller 20 also roll, ensuring smooth and continuous movement of the entire sliding body.

[0097] The adsorption component includes a miniature vacuum diaphragm pump 23. A placement chamber 24 is provided in the second horizontal plate 5. The miniature vacuum diaphragm pump 23 is located in the placement chamber 24. The miniature vacuum diaphragm pump 23 has an exhaust port and an exhaust port. A gas channel 25 is provided in the connecting plate 6 that passes through the connecting plate 6 in the direction of its thickness. The gas channel 25 has a gas inlet and a gas outlet. The gas inlet is located on the lower surface of the connecting plate 6, and the gas outlet is located on the upper surface of the connecting plate 6. The exhaust port is connected to an exhaust pipe 26, which passes through the second horizontal plate 5 and is connected to the gas outlet. The exhaust port is connected to an exhaust pipe 27, which passes through the second horizontal plate 5 and is connected to the storage box 3. The miniature vacuum diaphragm pump 23 is electrically connected to the microprocessor.

[0098] In this embodiment, the model of the micro vacuum diaphragm pump 23 is: TRN large-flow micro air pump, corrosion-resistant high vacuum diaphragm pump. A placement chamber 24 is provided in the second horizontal plate 5 to provide installation space for the micro vacuum diaphragm pump 23. A gas channel 25 is provided in the connecting plate 6 that runs through it along its thickness direction. The gas inlet of the gas channel 25 is located on the lower surface of the connecting plate 6, and the gas outlet is located on the upper surface of the connecting plate 6. The gas outlet is connected to the exhaust port of the micro vacuum diaphragm pump 23 through the exhaust pipe 26, thereby forming a complete gas passage. This setting method enables the gas between the sliding car body and the I-beam to be effectively sucked out, thereby forming a stable negative pressure environment. Through the negative pressure effect, the sliding car body can be firmly adsorbed on the surface of the I-beam, thereby ensuring stability and safety during operation.

[0099] The exhaust port of the micro vacuum diaphragm pump 23 is connected to the storage tank via an exhaust pipe 27. When the micro vacuum diaphragm pump 23 is operating, it continuously extracts gas between the sliding vehicle body and the I-beam through the exhaust pipe 26. This gas enters the exhaust pipe 27 through the exhaust port and is ultimately transported into the storage tank 3. As gas is continuously introduced, the internal pressure of the storage tank 3 gradually increases, providing power for the delivery of the fire retardant coating and ensuring that the fire retardant coating can flow steadily through the discharge port to the spraying structure.

[0100] The upper surface of the first transverse plate 4 is provided with two first slides 28 extending and parallel to the length thereof, and the bottom of the storage box 3 is provided with two first moving blocks 29 corresponding one-to-one to the first slides 28, and the first moving blocks 29 can move along the first slides 28 corresponding thereto. The upper surface of the second transverse plate 5 is provided with two second slides 30 extending and parallel to the length thereof, and the bottom of the storage box 3 is provided with two second moving blocks 31 corresponding one-to-one to the second slides 30, and the second moving blocks 31 can move along the second slides 30 corresponding thereto.

[0101] In this embodiment, when the width of the sliding vehicle body needs to be adjusted, the operator adjusts the distance between the first transverse plate 4 and the second transverse plate 5. During the process of adjusting the distance between the first transverse plate 4 and the second transverse plate 5, the first transverse plate 4 and the second transverse plate 5 produce corresponding displacements. At this time, the two first slides 28 on the upper surface of the first transverse plate 4 and the corresponding first moving blocks 29 produce relative sliding, while the two second slides 30 on the upper surface of the second transverse plate 5 and the corresponding second moving blocks 31 produce relative sliding. This arrangement ensures that during the process of adjusting the distance between the first transverse plate 4 and the second transverse plate 5, the storage box 3 can follow the movement of the first transverse plate 4 and the second transverse plate 5 and produce relative displacement, thereby ensuring the smoothness of the adjustment process and the stability of the storage box 3.

[0102] See also Figure 3 and Figure 4As shown, the spraying structure includes a metal bellows 32 that can be bent along the outer contour of the I-beam and can surround the surface of the I-beam. Both ends of the metal bellows 32 are closed, and the two ends of the metal bellows 32 are connected by a snap buckle 33. The metal bellows 32 is provided with a corrugated straight section and a turning section. All the corrugated straight sections are outer-circuited with a rigid metal tube 34. The corrugated straight sections are evenly distributed along their axial direction with several first nozzles facing the surface of the I-beam. A valve 35 is provided in the first nozzle. The rigid metal tube 34 is provided with a second nozzle corresponding to the first nozzle one by one. The first nozzle is provided with an atomizing nozzle 36 extending toward the corresponding second nozzle. The atomizing nozzle 36 has an atomizing outlet, which is connected to the corresponding second nozzle. The metal bellows 32 is connected to the discharge port of the storage box 3 toward the side wall of the storage box 3. The connecting component is detachably connected to the corresponding rigid metal tube 34. All valves 35 are electrically connected to the microprocessor.

[0103] In this embodiment, the metal bellows 32 is configured with straight and curved sections, allowing it to flexibly adapt to the contours of I-beams of varying sizes, thereby enhancing the flexibility and versatility of the spray coating structure. The metal bellows 32 can bend along the outer contour of the I-beam and wrap around the surface of the I-beam at equal intervals, ensuring that the sprayed fire retardant coating evenly covers the entire outer surface of the I-beam, thereby preventing uneven coating.

[0104] The metal bellows 32 is sealed at both ends and connected by a clip 33, making it easy to install. To install the metal bellows 32, the operator first releases the clip lock; then, unfolds the metal bellows 32 and wraps it around the surface of the I-beam; finally, closes the clip to secure the connection, completing the installation.

[0105] A rigid metal tube 34 is installed outside the straight section of the corrugated steel, enhancing its structural stability. This provides additional support, ensuring that the straight section maintains its fixed shape during the spraying process and resists deformation due to external impact or internal pressure fluctuations. By preventing deformation of the straight section, the rigid metal tube 34 ensures a precise spray path, allowing the fire retardant coating to be evenly and continuously applied to the I-beam surface, thereby improving spray quality.

[0106] The corrugated straight section has several primary nozzles evenly distributed along its axial direction. The rigid metal tube 34 is equipped with secondary nozzles corresponding to each of the first nozzles. Atomizing nozzles 36 are located within the first nozzles, extending toward their corresponding secondary nozzles. The atomizing outlets of atomizing nozzles 36 communicate with the corresponding secondary nozzles. The secondary nozzles on the rigid metal tube 34 provide a stable mounting position for atomizing nozzles 36, ensuring they can accurately spray the fire retardant coating through the atomizing outlets.

[0107] Among them, the first nozzles are evenly distributed along the axial direction of the straight section of the corrugation, so that the first nozzles match the contour of the I-beam, thereby ensuring that the sprayed paint can evenly cover the entire surface of the I-beam. Traditional spraying equipment has a wide spray range of a single nozzle, which easily exceeds the narrow upper flange plate, lower flange plate and web plate of the I-beam, resulting in waste of fire retardant paint and uneven coverage. The first nozzles evenly distributed along the axial direction of the straight section of the corrugation can accurately control the spray angle and range, so that the sprayed paint acts directly on the target surface, avoiding scattering and overspray. At the same time, the synergistic effect of several first nozzles can cover the entire surface of the I-beam, reducing the problems of missed spraying or uneven coating thickness, thereby improving spraying efficiency and coating quality.

[0108] The metal bellows 32 is connected to the discharge port of the storage box 3, facing the side wall of the storage box 3, to ensure that the paint can be smoothly transferred from the storage box 3 to the metal bellows 32. When the metal bellows 32 has been filled with material, the microprocessor activates the first and second sliding structures, driving the sliding body to move along the I-beam. Then, the valves 35 in all the first nozzles are opened, and the fire retardant paint in the metal bellows 32 is sprayed onto the surface of the I-beam through the atomizing nozzle 36.

[0109] A first feed port is provided on the side wall of the storage box 3 toward the straight section of the corrugated metal bellows 32, and a second feed port corresponding to the first feed port is provided on the rigid metal tube 34. The first feed port is connected to a feed pipe 37, and the end of the feed pipe 37 passes through the second feed port and is connected to the discharge port of the storage box 3.

[0110] In this embodiment, when an operator manually activates micro-vacuum diaphragm pump 23, it draws air from between the sliding carriage and the I-beam surface and transfers the air into the storage tank, which in turn increases the pressure within the tank. Driven by this pressure, the fire retardant coating within storage tank 3 is forced out of the discharge port and then transported through feed pipe 37 to metal bellows 32, completing the automatic supply of the fire retardant coating.

[0111] The connecting parts include several connecting rods 38, which are respectively located on the sides of the first horizontal plate 4, the second horizontal plate 5, the first fixed plate 7 and the second fixed plate 8 and extend toward the spraying structure. All connecting rods 38 are parallel to each other, and the ends of all connecting rods 38 are detachably connected to the corresponding rigid metal tubes 34.

[0112] In this embodiment, the connecting components include several connecting rods 38, which securely connect the first transverse plate 4, the second transverse plate 5, the first fixed plate 7, and the second fixed plate 8 to the rigid metal tube 34, forming a rigid, integrated structure between the sliding vehicle body and the spray coating structure. This arrangement effectively reduces the swaying of the spray coating structure during movement and improves its stability, thereby ensuring that the fire retardant coating is evenly sprayed onto the surface of the I-beam. Furthermore, the ends of the connecting rods 38 are detachably connected to the rigid metal tube 34, facilitating routine maintenance and adjustments and enhancing the flexibility and practicality of the spray coating structure.

[0113] In this embodiment, the movement of the first and second sliding structures can drive the sliding vehicle body to move accordingly. The spraying structure is connected to the side of the sliding vehicle body, and the uniform movement of the sliding vehicle body can drive the spraying structure to move accordingly. Compared with the existing technology, this embodiment ensures that the movement speed of the spraying structure is uniform and stable during the spraying process, avoiding the problem of uneven spray thickness caused by inconsistent movement speed during manual operation. In addition, this arrangement enables continuous spraying operations without relying on a lifting platform vehicle, thereby improving the efficiency and quality of the spraying operation while reducing the cost of spraying.

[0114] Secondly, the suction assembly draws air between the sliding body and the I-beam surface, ensuring it remains firmly and securely attached to the surface, preventing the sliding body from falling off during the spraying process. The suction assembly pumps the suctioned air into the storage tank to increase pressure, providing power for the fire retardant coating, ensuring a steady flow of the coating through the discharge port to the spraying mechanism. This reduces equipment costs compared to traditional mechanical pumping. Precise microprocessor control of the first and second sliding mechanisms, the suction assembly, and the spraying mechanism ensures coordinated operation, enabling intelligent climbing and spraying during the spraying process.

[0115] The above are only embodiments of the present invention, and common knowledge such as the specific technical solutions and / or characteristics in the solutions are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
