Description

Technical Field

[0001] This utility model belongs to the field of building construction, and in particular relates to a painting device for scaffolding. Background Technology

[0002] Scaffolding pipes are mainly used on construction sites as structural support materials for scaffolding, formwork supports, and guardrails. Before use, the surface of the scaffolding pipes needs to be painted, primarily for rust and corrosion prevention and functional identification. To meet the requirements of functional differentiation and safety warnings, scaffolding pipes typically need to be painted with two colors of paint. Currently, there is a difficulty in painting scaffolding pipes because they need to be clamped, moved, or rotated. Therefore, the clamped areas are obscured and cannot be painted, requiring separate manual treatment later, which reduces construction efficiency and increases labor costs. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a pipe painting device.

[0004] This invention is achieved through the following technical solution:

[0005] A painting device for scaffolding includes a support frame A and a support frame B, both of which have a material box on their upper part. Two long roller brushes are rotatably connected to the material box of support frame A via bearings. The upper surface of the long roller brushes is higher than the upper surface of the material box, and the distance between the two long roller brushes is less than the diameter of the scaffolding. Several partitions are evenly arranged inside the material box of support frame B, dividing the material box into several small material bins. Two short roller brushes are rotatably connected to each small material bin via bearings. The device also includes an internal support component with a crank handle fixed outward from its center. The internal support component can press against the inner wall of the scaffolding from inside the scaffolding, and rotating the crank handle rotates the scaffolding.

[0006] Preferably, the internal support component includes a cross support frame, with a short column fixed at the center of the inner side of the cross support frame. The end of the short column is rotatably connected to a large gear via a bearing. The large gear has four evenly distributed arc-shaped through slots. Each of the four rods of the cross support frame is provided with a slide rail, and a slide rod is provided in the slide rail. An arc-shaped support rod is fixed at the end of the slide rod. A guide post is vertically fixed on the side of the slide rod near the short column, and the guide post passes through the corresponding arc-shaped through slot. A micro motor is fixed on the cross support frame, and the shaft of the micro motor is fixedly connected to a small gear, which meshes with the large gear.

[0007] Preferably, either the long roller brush or the short roller brush is connected to the motor shaft, and the motor is mounted on the material box.

[0008] Preferably, the surface of the arc-shaped support rod is provided with a rubber pad layer.

[0009] This invention's painting device avoids the problem of paint not being applied to the clamping points of the scaffolding. The internal support structure not only clamps the scaffolding internally, eliminating external clamping points, but also allows for rotation and movement of the scaffolding, resulting in more even paint application and convenient movement. Compared to existing large-scale painting machinery, this device is less expensive, smaller, easier to transport, and suitable for a wider range of construction sites. It is also simple to operate, requiring no separate training. Both the long and short roller brushes of this device rotate automatically, eliminating the need for manual rotation to pick up paint and further ensuring even coating. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0019] This embodiment includes support frame A2 and support frame B3. Both support frames A2 and B3 have a material box 4 on their upper part. The material box 4 of support frames A2 and B3 respectively holds two colors of paint, such as the common two-color combination for the support tube 1, like red and white paint, yellow and white paint, etc. Two long roller brushes 5 are rotatably connected to the material box 4 of support frame A2 via bearings. The two long roller brushes 5 are located inside the material box 4 and can rotate. The length of the long roller brushes 5 is slightly greater than the length of the support tube 1 to be painted, and the upper surface of the long roller brushes 5 is higher than the upper surface of the material box 4. The distance between the two long roller brushes 5 is less than the diameter of the support tube 1, so that when the support tube 1 is placed on the two long roller brushes 5, the support tube 1 will not leak between the two long roller brushes 5.

[0020] Several partitions 6 are evenly arranged inside the material box 4 of the support frame B3, dividing the material box 4 of the support frame B3 into several small material bins 7. Two short roller brushes 8 are rotatably connected to each small material bin 7 via bearings. The short roller brushes 8 can rotate within the small material bin 7. The length of the short roller brushes 8 is determined according to the width of each section of paint to be applied. For example, if each section of white paint on the red and white striped support tube 1 is 60cm wide, and each section of red paint is 60cm wide, then the length of the short roller brushes 8 is set to 60cm. The small material bins 7 containing the short roller brushes 8 hold paint; the small material bins 7 without the short roller brushes 8 are empty.

[0021] To ensure more even paint application on the support tube 1, and to guarantee a sufficient supply of paint on both the long roller brush 5 and the short roller brush 8, preventing manual manipulation of the paint, it is preferable to connect the shaft of a motor 9 to either end of the long roller brush 5 or the short roller brush 8. The motor 9 drives either the long roller brush 5 or the short roller brush 8 to rotate, thereby picking up paint from the paint box 4. The motor 9 is mounted on the paint box 4. In this embodiment, the motor 9 at the end of the long roller brush 5 is mounted on a support plate 22, which is fixed to the outer surface of the paint box 4. The motor 9 at the end of the short roller brush 8 is also mounted on the support plate 22, which is fixed to the partition plate 6.

[0022] The device of the present invention also includes an inner support component 10, which is used to move and rotate the frame tube 1. There are no external clamping parts during painting, thus eliminating areas that cannot be painted. A crank handle 11 is fixed outward from the center of the inner support component 10. The inner support component 10 can tightly press against the inner wall of the frame tube 1 from inside, and rotating the crank handle 11 causes the frame tube 1 to rotate together. The inner support component 10 can extend into the frame tube 1, and its diameter can increase inside the frame tube 1 to press against it, making the frame tube 1 and the inner support component 10 an integral unit. Various structures of the inner support component 10 can achieve this function, and the present invention does not impose any special limitations on them. In this embodiment, a preferred inner support component 10 is described, with the following specific structure: The inner support component 10 includes a cross support frame 12, and a crank handle 11 is fixedly connected outward from the center of the outer side of the cross support frame 12. Here, "outer" refers to the side of the inner support component 10 near the opening of the frame tube 1 after it is placed inside the frame tube 1. A short column 13 is fixed at the center of the inner side of the cross support frame 12. The end of the short column 13 is rotatably connected to a large gear 14 via a bearing, and the large gear 14 can rotate around the short column 13. Four arc-shaped through grooves 15 are evenly distributed on the large gear 14, arranged in a ring around the center of the large gear 14. The four arc-shaped through grooves 15 correspond one-to-one with the four rods of the cross support frame 12, and the four arc-shaped through grooves 15 are curved in the same direction. Each of the four rods of the cross support frame 12 is provided with a slide rail 16, and a slide rod 17 is provided in the slide rail 16, which can slide along the slide rail 16. An arc-shaped support rod 18 is fixed at the end of the slide rod 17. The arc of the arc-shaped support rod 18 matches the arc of the frame tube 1, and the arc-shaped support rod 18 is used to contact the inner wall of the frame tube 1, tightly pressing against the inner wall of the frame tube 1. To increase the contact force, it is preferable that the surface of the arc-shaped support rod 18 is provided with a rubber pad layer. A guide post 19 is vertically fixed on the side of the slide rod 17 near the short post 13, and the guide post 19 passes through the corresponding arc-shaped through groove 15. A micro motor 20 is fixed on the cross support frame 12, and the shaft of the micro motor 20 is fixedly connected to a small gear 21, which meshes with a large gear 14. The micro motor 20 drives the small gear 21 to rotate, which in turn drives the large gear 14 to rotate. The rotation of the large gear 14 causes the arc-shaped through groove 15 to rotate as a whole. The rotation of the arc-shaped through groove 15 causes the guide post 19 to slide along the arc-shaped through groove 15, thereby causing the slide rod 17 to slide in a straight line along the slide rail 16. Finally, the arc-shaped support rod 18 slides towards the inner wall of the frame tube 1 to abut against the inner wall of the frame tube 1, or the arc-shaped support rod 18 moves away from the inner wall of the frame tube 1, and the diameter of the inner support component 10 becomes smaller, allowing it to be moved out of the frame tube 1. When the arc-shaped support rod 18 is pressed tightly against the inner wall of the scaffold tube 1, turning the crank handle 11 can make the scaffold tube 1 rotate together, or you can grab the crank handle 11 to move the scaffold tube 1.

[0023] This embodiment uses the example of painting red and white stripes on a scaffold tube 1 to illustrate the usage process. The material box 4 of support frame A2 contains white paint, and the small material bin 7 on support frame B3, containing short roller brushes 8, contains red paint. The motor 9 is turned on, causing the long roller brushes 5 and short roller brushes 8 to rotate slowly, with their bottom surfaces submerged in paint. Two workers hold the crank handle 11 and insert two internal support components 10 into the ends of the scaffold tube 1, respectively. This allows the micro motor 20 to rotate, driving the small gear 21 and large gear 14 to rotate. The sliding rod 17 slides away from the center of the large gear 14 until the arc-shaped support rod 18 firmly presses against the inner wall of the scaffold tube 1. Then, the workers at both ends hold the crank handle 11 and lift the scaffold tube 1 to support frame A2, placing it on the two long roller brushes 5. The workers at both ends turn the crank handle 11 to rotate the scaffold tube 1 on the two long roller brushes 5, coating it with white paint. Then... The worker then holds the crank handle 11 and moves the scaffold tube 1 onto the support frame B3. The scaffold tube 1 is placed on the short roller brush 8. The crank handle 11 is turned again to paint a section of red paint on the scaffold tube 1 at regular intervals, thus forming a red and white paint pattern on the scaffold tube 1. The worker then holds the crank handle 11 and lifts the scaffold tube 1 aside to dry. The micro motor 20 is started again and rotated in the opposite direction, causing the slide bar 17 to slide towards the center of the large gear 14. At this time, the inner support component 10 is reduced in size and removed from the scaffold tube 1. The painting work of the next scaffold tube 1 is repeated.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
