Description

Technical Field

[0001] This application relates to the field of building construction technology, specifically to a high-strength steel large-span space fireproof coating spraying equipment. Background Technology

[0002] With the rapid development of modern construction technology, large-span steel structure buildings occupy an important position in urban skylines due to their unique spatial aesthetics and structural efficiency. High-strength steel, as the core material of these buildings, significantly reduces building weight and construction costs thanks to its lightweight design and excellent load-bearing capacity. However, the defect of high-strength steel being prone to softening and failure at high temperatures limits its direct application in scenarios with strict fire protection requirements. Therefore, applying professional fire-retardant coatings to form a heat insulation barrier has become a key technical approach to ensure the fire resistance limit of steel structures.

[0003] Currently, the industry generally uses intumescent fire-retardant coatings, but traditional manual spraying has problems such as low efficiency, uneven thickness, and safety hazards of high-altitude operations. Therefore, there is a need for a high-strength steel large-span space fire-retardant coating spraying equipment to carry out fire-retardant coating spraying operations for large-span steel structure buildings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a high-strength steel large-span space fireproof coating spraying equipment, which can automatically complete the spraying of fireproof coatings on the surface of large-span steel structures and clean the steel structure surface simultaneously, avoiding manual labor, improving work efficiency, ensuring spraying quality and construction safety, and solving the problems of low efficiency, uneven thickness, and safety hazards of high-altitude operations in traditional manual fireproof coating spraying.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-strength steel large-span space fireproof coating spraying equipment, comprising a base plate, a spraying mechanism on the upper surface of the base plate, a first pipe fixedly connected inside the spraying mechanism, and spray pipes arranged at equal intervals connected to the outer circumferential surface of the first pipe, each spray pipe having a nozzle fixedly connected to its bottom, a support on the upper surface of the base plate, an electric cylinder fixedly connected to the upper surface of the support, a frame fixedly connected to the output end of the electric cylinder, a cleaning roller rotatably connected inside the frame, a cleaning brush fixedly connected to the outer circumferential surface of the cleaning roller, a dust collection mechanism on the upper surface of the base plate, a second pipe fixedly connected inside the dust collection mechanism, and dust collection pipes arranged at equal intervals connected to the outer circumferential surface of the second pipe, and a magnetic adsorption wall-climbing robot located below one end of the base plate.

[0006] The above solution addresses the problems of low efficiency, uneven thickness, and safety hazards associated with high-altitude operations in traditional manual fireproof coating spraying. By setting up a magnetically adsorbed wall-climbing robot, a spraying mechanism, a first pipeline, and equidistantly arranged spray pipes and nozzles, the solution can automatically replace manual labor in spraying fireproof coatings on the surface of large-span steel structures, thereby improving work efficiency and ensuring spraying quality and construction safety.

[0007] Furthermore, the bottom of the base plate is fixedly connected to the magnetically adsorbed wall-climbing robot by bolts.

[0008] The above solution uses bolts to connect and fix the base plate and the magnetically adsorbed wall-climbing robot, which not only ensures the stability of the connection between the two, but also facilitates the installation and disassembly of the base plate.

[0009] Furthermore, a servo motor is provided on one side of the frame, and the output end of the servo motor is fixedly connected to one end of the cleaning roller.

[0010] Through the above scheme, the servo motor can provide power to the cleaning roller, drive the cleaning roller and cleaning brush to rotate, and thus complete the rotational cleaning operation on the steel structure surface.

[0011] Furthermore, a first sleeve is fixedly fitted onto the outer circumferential surface of each nozzle, and the outer circumferential surface of the first sleeve is fixedly connected to the interior of the base plate.

[0012] The above-mentioned method supports and reinforces the nozzle, improving its stability during operation.

[0013] Furthermore, the bracket is fixedly connected to the base plate by bolts, and the outer surface of the bracket is fixedly connected with triangular reinforcing plates arranged at equal intervals.

[0014] The above solution uses bolts to connect and fix the base plate and the bracket, ensuring the stability of the connection between the two and facilitating the installation and disassembly of the bracket. The triangular reinforcing plate effectively increases the structural strength and stability of the bracket.

[0015] Furthermore, two guide rods are fixedly connected to the upper surface of the frame, and the outer circumferential surface of the guide rods is slidably inserted into the interior of the bracket.

[0016] The above scheme guides and restricts the frame, causing it to move vertically, which in turn drives the cleaning roller and cleaning brush to move vertically, thus improving the stability of the frame during its lifting motion.

[0017] Furthermore, a second sleeve is fixedly fitted onto the outer circumferential surface of each of the vacuum tubes, and the outer circumferential surface of the second sleeve is fixedly connected to the interior of the bracket.

[0018] The above solutions provide support and reinforcement for the vacuum cleaner hose, preventing it from loosening or shifting during operation and causing damage.

[0019] Furthermore, the bottom of each of the suction tubes is bent at a certain angle toward the cleaning roller.

[0020] The above method ensures that the suction end of the suction pipe is aligned with the cleaning position of the cleaning roller, thereby optimizing the suction effect of the suction pipe.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This high-strength steel, large-span space fireproof coating spraying equipment, by incorporating a magnetic adsorption wall-climbing robot, a spraying mechanism, a first pipeline, and equidistantly arranged spray pipes and nozzles, can automatically replace manual labor to complete the spraying of fireproof coatings on the surface of large-span steel structures. This improves work efficiency, ensures spraying quality, and guarantees construction safety. By incorporating an electric cylinder, frame, cleaning roller, cleaning brush, and servo motor, the equipment can clean the surface of the steel structure during the spraying process, preventing dirt on the steel structure surface from affecting the spraying effect and further improving the spraying quality. By incorporating a dust collection mechanism, a second pipeline, and equidistantly arranged dust collection pipes, the equipment can collect the floating dust generated during the cleaning process, preventing dust from contaminating the working environment and the fireproof coating, and further optimizing the spraying effect.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a high-strength steel large-span space fireproof coating spraying equipment includes a base plate 1, a spraying mechanism 2 on the upper surface of the base plate 1, a first pipe 3 fixedly connected inside the spraying mechanism 2, and spray pipes 4 arranged at equal intervals connected to the outer circumference of the first pipe 3. Each spray pipe 4 is fixedly connected to a nozzle 5 at its bottom. A bracket 6 is provided on the upper surface of the base plate 1, an electric cylinder 7 is fixedly connected to the upper surface of the bracket 6, a frame 8 is fixedly connected to the output end of the electric cylinder 7, a cleaning roller 9 is rotatably connected inside the frame 8, a cleaning brush 10 is fixedly connected to the outer circumference of the cleaning roller 9, a dust collection mechanism 11 is provided on the upper surface of the base plate 1, a second pipe 12 is fixedly connected inside the dust collection mechanism 11, and a dust collection pipe 13 arranged at equal intervals is connected to the outer circumference of the second pipe 12. A magnetic adsorption wall-climbing robot 14 is provided below one end of the base plate 1.

[0033] Please see Figure 2 , Figure 3 and Figure 6 The bottom of the base plate 1 is fixedly connected to the magnetic adsorption wall-climbing robot 14 by bolts. The connection and fixation of the base plate 1 and the magnetic adsorption wall-climbing robot 14 by bolts can not only ensure the stability of the connection between the two, but also facilitate the installation and disassembly of the base plate 1.

[0034] Please see Figure 1 , Figure 4 and Figure 5 A servo motor 15 is provided on one side of the frame 8. The output end of the servo motor 15 is fixedly connected to one end of the cleaning roller 9. The servo motor 15 can provide power to the cleaning roller 9, drive the cleaning roller 9 and the cleaning brush 10 to rotate, and thus complete the rotation cleaning operation on the surface of the steel structure.

[0035] Please see Figure 1 , Figure 2 and Figure 3 Each nozzle 4 has a first sleeve 16 fixedly fitted on its outer circumference. The outer circumference of the first sleeve 16 is fixedly connected to the inside of the base plate 1 to support and reinforce the nozzle 4, thereby improving the stability of the nozzle 4 during operation.

[0036] Please see Figure 1 and Figure 2 The bracket 6 is fixedly connected to the base plate 1 by bolts. The outer surface of the bracket 6 is fixedly connected with equidistantly arranged triangular reinforcing plates 17. The connection and fixation between the base plate 1 and the bracket 6 by bolts can ensure the stability of the connection between the two, and at the same time facilitate the installation and disassembly of the bracket 6. The triangular reinforcing plates 17 can effectively increase the structural strength and stability of the bracket 6.

[0037] Please see Figure 1 , Figure 4 and Figure 5 Two guide rods 18 are fixedly connected to the upper surface of the frame 8. The outer circumferential surface of the guide rods 18 is slidably inserted into the inside of the bracket 6 to guide and restrict the frame 8, so that the frame 8 always moves vertically up and down, thereby driving the cleaning roller 9 and the cleaning brush 10 to move vertically up and down, improving the stability of the frame 8 during the lifting and lowering process.

[0038] Please see Figure 1 , Figure 2 and Figure 4 Each suction pipe 13 has a second sleeve 19 fixedly fitted on its outer circumference. The outer circumference of the second sleeve 19 is fixedly connected to the inside of the bracket 6 to support and reinforce the suction pipe 13, preventing it from loosening or shifting during operation and causing damage to the suction pipe 13.

[0039] Please see Figure 1 , Figure 2 and Figure 4 Each suction pipe 13 has its bottom bent at a certain angle toward the cleaning roller 9, causing the suction end of the suction pipe 13 to face the cleaning position of the cleaning roller 9, thereby optimizing the suction effect of the suction pipe 13.

[0040] This embodiment of a high-strength steel large-span space fireproof coating spraying equipment, by setting up a magnetic adsorption wall-climbing robot 14, a spraying mechanism 2, a first pipe 3, equidistantly arranged spray pipes 4 and nozzles 5, can automatically replace manual labor to complete the spraying of fireproof coating on the surface of large-span steel structures, improving work efficiency, ensuring spraying quality and construction safety. By setting up an electric cylinder 7, a frame 8, a cleaning roller 9, a cleaning brush 10 and a servo motor 15, the surface of the steel structure can be cleaned during the spraying operation to avoid dirt on the steel structure surface affecting the spraying effect and further improve the spraying quality. By setting up a dust collection mechanism 11, a second pipe 12 and equidistantly arranged dust collection pipes 13, the floating dust generated during the cleaning process can be recovered to avoid dust contamination of the working environment and fireproof coating, further optimizing the spraying operation effect.

[0041] It should be noted that the dust collection mechanism 11 has a detachable dust collection box inside, which can store the collected dust for subsequent dust treatment. When spraying the fireproof coating, it is necessary to spray from top to bottom to avoid the dirt cleaned by the cleaning brush 10 from contaminating the sprayed fireproof coating.

[0042] The working principle of the above embodiments is as follows:

[0043] The equipment moves and positions itself via a magnetically attached wall-climbing robot 14 located below one end of the base plate 1. The robot, with its strong magnetic adsorption capability, firmly adheres to the surface of a large-span steel structure and moves according to a preset path and program. During movement, a servo motor 15 located on one side of the frame 8 is activated. The servo motor 15 outputs power to drive the cleaning roller 9 to rotate, causing the cleaning brush 10 on the outer circumference of the cleaning roller 9 to rotate accordingly. This cleaning action cleans the steel structure surface during movement. Simultaneously, a vacuuming mechanism 11 is activated, generating strong suction that draws the cleaning fluid through the second pipe 12 and the suction pipe 13. The generated dust is sucked in and transported to the dust collection box inside the dust collection mechanism 11 for storage, preventing dust from contaminating the working environment and fireproof coating. The frame 8 can be vertically raised and lowered by controlling the extension and retraction of the electric cylinder 7 to adapt to steel structure surfaces of different heights and shapes. While the cleaning operation is underway, the spraying mechanism 2 is activated to transport the spraying material through the first pipe 3 to each spray pipe 4, and then spray it evenly from the nozzle 5 onto the cleaned steel structure surface. With the continuous movement of the magnetic adsorption wall-climbing robot 14, the equipment simultaneously cleans and sprays the surface of the steel structure, replacing manual labor to complete the fireproof coating spraying operation, improving work efficiency, and ensuring spraying quality and construction safety.
