Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a fireproof coating spraying device. Background Technology

[0002] Steel structure buildings are increasingly favored by designers due to their lightweight, high strength, good overall rigidity, strong deformation capacity, and long service life. In particular, steel structure buildings, such as non-inflatable steel structures, are often used in workshops with large spans. However, non-inflatable steel structures have lower fire resistance and require the application of fire-retardant coatings to improve their fire resistance.

[0003] A search revealed a Chinese patent publication number CN222586967U, which discloses a spraying equipment for fireproof coatings on steel structures. The equipment includes a base, a motor I fixedly mounted on the side of the base, a threaded rod fixedly mounted on the output shaft of motor I, a slider threaded onto the outer wall of the threaded rod, an electric telescopic rod fixedly mounted on the top of the slider, a support plate fixedly mounted on the top of the electric telescopic rod, a spray nozzle mounted on the bottom of the support plate, cylinders symmetrically mounted on the side of the base, a moving plate fixedly mounted on the side of the cylinders, a second motor fixedly mounted on the side of the moving plate, and a rotating shaft fixedly mounted on the output shaft of the second motor.

[0004] This patented device uses multiple adjustable limit blocks to clamp and fix steel pipes of different diameters, allowing the pipes to rotate and ensuring uniform paint spraying. A dust suction hood on the side of the nozzle absorbs any drifting paint, improving the device's versatility. However, when the cleaning brush cleans the outer wall of the steel pipe, impurities fall randomly onto the base, making collection difficult. Furthermore, if impurities fall onto the outer wall of the threaded rod, they may obstruct the movement of the slider along the threaded rod. Utility Model Content

[0025] Example 1: A fire-retardant coating spraying device, such as Figures 1 to 4As shown, the system includes a base plate 1. A linear motion assembly 7 is provided on the top outer wall of the base plate 1. The linear motion assembly 7 includes a sliding groove, a screw, a drive motor, and a slider. The linear motion assembly 7 is a mature existing technology, and its basic structure and working principle are well known to those skilled in the art, so it will not be described in detail here. An electric turntable 8 is installed on the top outer wall of the slider of the linear motion assembly 7. A telescopic rod 9 is fixed on the top outer wall of the electric turntable 8. A support plate 10 is fixed at the top of the telescopic rod 9. An air suction hood 11 is provided on the bottom outer wall of the support plate 10. The air suction hood 11 is H-shaped. A cleaning brush 12 and a nozzle 13 are provided on the inner side of the air suction hood 11. The air suction hood 11 is connected to an external suction structure, and the nozzle 13 is connected to an external paint delivery structure.

[0026] The linear motion component 7 has guide grooves 15 arranged opposite to each other on both sides. The inner walls of the two guide grooves 15 on the same side of the linear motion component 7 are rotatably connected to the same bidirectional screw 14. A moving motor that drives the bidirectional screw 14 to rotate is installed on the side wall of the base plate 1. A moving block 17 is slidably fitted on the inner wall of the guide groove 15. The moving block 17 is threadedly fitted to the outer wall of the bidirectional screw 14. A folding protective cover 16 is connected to the side wall of the moving block 17. The other end of the folding protective cover 16 is connected to the inner wall of the guide groove 15. A telescopic rod 2 is fixed on the top outer wall of the moving block 17. A fixing plate 3 is fixed to the top telescopic end of the telescopic rod 2. A fixing component 4 is provided on one side outer wall of the fixing plate 3.

[0027] The fixing assembly 4 includes a central cylinder 18 and multiple cams 19. The central cylinder 18 is rotatably connected to the outer wall of the fixing plate 3, and the cams 19 are rotatably connected to the inner wall of the central cylinder 18. The multiple cams 19 are arranged in a straight line. A rotary motor for driving the central cylinder 18 is installed on the outer wall of either of the two opposing fixing plates 3. Multiple fixing rods 20 arranged axially around the axis of the central cylinder 18 are slidably fitted on the outer wall of the central cylinder 18. One end of the fixing rod 20 is in slidable contact with the outside of the cam 19. The outer wall of the fixing rod 20 is provided with an annular protrusion. A spring 21 is sleeved on the outer wall of the fixing rod 20. The two ends of the spring 21 are respectively connected to the annular protrusion and the central cylinder 18. A rotary motor for driving the cams 19 is fixed on one side of the outer wall of the central cylinder 18.

[0028] During spraying, a steel pipe is transported between two fixing assemblies 4, a moving motor drives a bidirectional screw 14 to rotate, so that two fixing plates 3 approach each other, and central cylinders 18 are inserted into both ends of the steel pipe. Then a rotating motor drives a cam 19 to rotate, pushing a fixing rod 20 to move away from the axis of the central cylinder 18, so that one end of the fixing rod 20 abuts against and fixes the inner wall of the steel pipe. Then a second telescopic rod 9 drives a support plate 10 to descend, so that a cleaning brush disc 12 contacts the outer wall of the steel pipe. Then a rotating motor drives the central cylinder 18 to rotate, driving the steel pipe to rotate, the cleaning brush disc 12 cleans the outer wall of the steel pipe, after cleaning, a spray head 13 sprays the outer wall of the steel pipe, an external suction structure sucks away and collects the cleaned impurities through a suction hood 11 located outside the cleaning brush disc 12, meanwhile the suction hood 11 can also collect scattered paint liquid to avoid air pollution. During the spraying process of one steel pipe, a user can fix another steel pipe on the other side of a bottom plate 1, after spraying is completed, an electric turntable 8 rotates to make the support plate 10 rotate 180 degrees, and spray the already fixed steel pipe.

[0029] By arranging the suction hood 11 in a shape of Chinese character "ri", the suction hood 11 surrounds the outside of the cleaning brush disc 12 and the spray head 13, which can suck away and collect the cleaned impurities, prevent impurities from scattering on the surface of the bottom plate 1, and collect scattered paint liquid to avoid air pollution.

[0030] By arranging the electric turntable 8 and the fixing plates 3, the fixing assemblies 4, the bidirectional screw 14, the guide groove 15, the folding protective cover 16, the moving block 17 and the central cylinder 18 which are located on both sides of a linear moving assembly 7, another steel pipe can be loaded and fixed during the spraying process, which reduces loading time and improves spraying efficiency.

[0031] Example 2: A fireproof coating spraying device, this embodiment makes the following improvements on the basis of Embodiment 1, as Figure 1 shows, a support block 5 is fixed on the top outer wall of the bottom plate 1, the support block 5 is located between two fixing assemblies 4 on the same side of the bottom plate 1, the top outer wall of the support block 5 is arc-shaped, and a friction plate 6 is fixed on the top outer wall of the support block 5.

[0032] When fixing the steel pipe, the steel pipe can be lifted and placed above the friction plate 6, then the fixing plate 3 moves towards the friction plate 6, so that the central cylinder 18 is inserted into the steel pipe for fixation, then a first telescopic rod 2 pushes the fixing plate 3 to move upward, driving the steel pipe to move upward and away from the friction plate 6, which does not require the user to maintain the state of the steel pipe all the time before the central cylinder 18 is inserted into the steel pipe for fixation, and facilitates the alignment of the steel pipe and the central cylinder 18.

[0033] By arranging the support block 5 and the friction plate 6, the steel pipe can be supported, which does not require the user to maintain the state of the steel pipe all the time before the central cylinder 18 is inserted into the steel pipe for fixation, and facilitates the alignment of the steel pipe and the central cylinder 18.

[0034] Working principle: During spraying, a steel pipe is moved between two fixed components 4 and placed above the friction plate 6. The moving motor drives the bidirectional screw 14 to rotate, bringing the two fixed plates 3 closer together. The central cylinder 18 is inserted into both ends of the steel pipe. Then, the rotating motor drives the cam 19 to rotate, pushing the fixed rod 20 away from the axis of the central cylinder 18. One end of the fixed rod 20 is fixed against the inner wall of the steel pipe. The telescopic rod 2 pushes the fixed plate 3 upward, moving the steel pipe upward away from the friction plate 6. This eliminates the need for the user to maintain the state of the steel pipe before the central cylinder 18 is inserted and fixed, and facilitates the alignment of the steel pipe with the central cylinder 18. Then, the telescopic rod 9 drives the support... The plate 10 descends, bringing the cleaning brush 12 into contact with the outer wall of the steel pipe. Then, the rotating motor drives the central cylinder 18 to rotate, causing the steel pipe to rotate. The cleaning brush 12 cleans the outer wall of the steel pipe, and the spray nozzle 13 sprays the outer wall of the steel pipe after cleaning. The external suction structure uses the suction hood 11 located outside the cleaning brush 12 to suck away and collect the impurities that have been cleaned. At the same time, the suction hood 11 can also collect the scattered paint liquid to avoid polluting the air. During the spraying of one steel pipe, the user can fix another steel pipe to the other side of the base plate 1. After the spraying is completed, the electric turntable 8 rotates, causing the support plate 10 to rotate 180 degrees to spray the fixed steel pipe.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
