Description

Technical Field

[0001] This utility model relates to the field of steel pipe painting technology, and in particular to a painting device for red and white striped steel pipes. Background Technology

[0002] In modern industrial and municipal construction, red and white painted steel pipes are widely used in traffic warning posts, construction scaffolding, power safety barriers, and other applications. Their striking color combination plays a crucial role in safety signage and media differentiation. Currently, painting these steel pipes mostly relies on traditional manual brushing or simple mechanical devices. In construction, steel pipes (such as guardrails and warning sign poles) often need to be painted with red and white warning colors. Traditional methods involve manual, segmented painting, which suffers from low efficiency, irregular color boundaries, and significant paint waste. Furthermore, multiple manual operations can lead to uneven coating thickness, affecting aesthetics and warning effectiveness.

[0003] While existing automated coating equipment can improve efficiency, most of them are designed for single-color spraying. For alternating red and white coating, multiple disassemblies and reassemblies of the workpiece are required to switch paints, which is time-consuming and can easily lead to paint waste and cross-contamination. Existing mechanical painting equipment is mostly designed for single colors or large components, and lacks a two-color segmented automated painting solution for small and medium diameter steel pipes. In particular, it is difficult to accurately control the spacing between red and white colors and the coating quality.

[0004] Existing mechanical devices often have a simple structure, making it difficult to control the segment length and brushing boundary of red and white stripes. Furthermore, the equipment has poor versatility and cannot be adapted to steel pipes of different diameters. At the same time, there is serious waste of paint and insufficient environmental performance. Therefore, a painting device for red and white striped steel pipes is proposed to solve the above problems. Utility Model Content

[0018] As a further description of the above technical solution:

[0019] A rotating pulley three is fixedly connected to the outer side of the supporting rotating column two, that is, the end away from the rotating pulley two. A rotating track two is sleeved on the outer side of the rotating pulley three. A rotating pulley four is rotatably connected to the inner side of the rotating track two, that is, the end away from the rotating pulley three.

[0020] As a further description of the above technical solution:

The first rotating pulley, connected to the supporting column, drives the painting sponge to rotate, applying red paint to the steel pipe after it has been painted white, creating a red and white alternating effect. The multi-wheel transmission achieves synchronous rotation of the steel pipe and the brush, reducing manual intervention through mechanical transmission, improving painting efficiency and pattern consistency, and reducing the scrap rate. It is suitable for mass production scenarios. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a painting device for red and white alternating steel pipes, including a supporting dyeing cylinder 1, which serves as the basic support structure for the entire device and also accommodates excess paint dripping during the painting process to prevent pollution of the working environment. A clamping mechanism 2 is fixedly connected to the outside of the supporting dyeing cylinder 1, and a transmission mechanism 3 is rotatably connected to the outside of the supporting dyeing cylinder 1. The clamping mechanism 2 includes a driving assembly 21 for driving, and a connecting sliding block 22 is fixedly connected to the outside of the driving assembly 21. Supports are fixedly connected to both sides of the connecting sliding block 22. Rotating column 23, serving as the fulcrum of rotating connecting rod 24, converts the linear motion of sliding block 22 into the rotational motion of rotating connecting rod 24. Rotating connecting rod 24 is rotatably connected to the outside of supporting rotating column 23, transmitting the translational motion of supporting rotating column 23 to supporting connecting column 25, thus realizing the conversion of force direction. The outside of rotating connecting rod 24, i.e., the end away from supporting rotating column 23, is rotatably connected to supporting connecting column 25, connecting rotating connecting rod 24 and connecting rotating block 26 to form a linkage mechanism, ensuring the synchronization of clamping actions;

[0033] A connecting rotating block 26 is rotatably connected to the outside of the supporting connecting column 25. It rotates around a fixed fulcrum on the supporting dyeing cylinder 1, driving the clamping fixing ring 27 to move. The clamping fixing ring 27 is fixedly connected to the outside of the connecting rotating block 26. By rotating inward, it clamps the fixed connecting ring 28. An anti-slip rubber pad is provided on the inner side to enhance friction. The fixed connecting ring 28 is slidably connected to the inner side of the clamping fixing ring 27 and is connected to the painting steel pipe 29. The clamping force is evenly transmitted to the steel pipe to ensure stable rotation. The painting steel pipe 29 is fixedly connected to the inner side of the fixed connecting ring 28. The outside of the painting steel pipe 29 is rotatably connected to the inside of the supporting dyeing cylinder 1. The outside of the clamping fixing ring 27 is slidably connected to the outside of the supporting dyeing cylinder 1. The outside of the connecting rotating block 26 is rotatably connected to the outside of the supporting dyeing cylinder 1.

[0034] The external rotating connecting rod 24 is rotatably connected to the outside of the supporting dyeing cylinder 1, the external sliding block 22 is slidably connected to the outside of the supporting dyeing cylinder 1, the external sliding supporting rotating column 23 is slidably connected to the outside of the supporting dyeing cylinder 1, the driving assembly 21 includes a telescopic cylinder 211, which provides linear driving force to push the piston rod to move, the driving end of the telescopic cylinder 211 is fixedly connected to a connecting telescopic rod 212, which transmits the driving force of the cylinder to the connecting sliding block 22, and the movement direction is limited by the guide rail on the supporting dyeing cylinder 1, the external telescopic cylinder 211 is fixedly connected to the outside of the supporting dyeing cylinder 1, the external sliding connecting rod 212 is slidably connected to the outside of the supporting dyeing cylinder 1, and the external fixed connecting rod 212 is fixedly connected to the outside of the connecting sliding block 22.

[0035] Reference Figures 1 to 3 The transmission mechanism 3 includes a rotary motor 31, which provides rotational power and drives the first rotary pulley 32 to rotate synchronously through the motor shaft. The drive end of the rotary motor 31 is fixedly connected to the first rotary pulley 32, which serves as the drive wheel. The power is transmitted to the second rotary pulley 34 through the first rotary track 33. The first rotary track 33 is sleeved on the outside of the first rotary pulley 32 to ensure stable transmission and realize speed transmission. The inner side of the first rotary track 33, i.e. the end away from the first rotary pulley 32, is rotatably connected to the third rotary pulley 35. The second rotary track 37 drives the fourth rotary pulley 38 to realize the synchronous rotation of multiple sets of steel pipes.

[0036] The rotating pulley 35 is internally connected to the supporting rotating column 2 36, which is mounted on the supporting dyeing cylinder 1 via bearings. It supports the rotating pulley 2 34 and the rotating pulley 3 35 and transmits the rotation to the painting steel pipe 29. The rotating pulley 2 34 is fixedly connected to the outside of the supporting rotating column 2 36 and is coaxially fixed to the supporting rotating column 2 36 with the rotating pulley 3 35, rotating synchronously. The rotating pulley 3 35 is fixedly connected to the outside of the supporting rotating column 2 36, i.e., the end away from the rotating pulley 2 34. The rotating track 2 37 is sleeved on the outside of the rotating pulley 3 35 to ensure smooth power transmission. The rotating pulley 4 38 is rotatably connected to the inside of the rotating track 2 37, i.e., the end away from the rotating pulley 3 35. The connecting support column 39 is fixedly connected to the outside of the rotating pulley 1 32 and is coaxially fixed to the rotating pulley 1 32. It rotates with the pulley and drives the painting sponge 310 to rotate around the surface of the steel pipe.

[0037] Multiple painting sponges 310 are fixedly connected to the external of the connecting support column 39. They are soaked in red paint and are applied by contacting the surface of the rotating steel pipe. The sponge material ensures that the paint layer is uniform and avoids scratching the steel pipe. The external of the painting sponge 310 is rotatably connected to the inside of the supporting dyeing tank 1. The external of the connecting support column 39 is rotatably connected to the inside of the supporting dyeing tank 1. The external of the rotating motor 31 is fixedly connected to the outside of the supporting dyeing tank 1. The external of the rotating pulley 2 34 and rotating pulley 35 is rotatably connected to the outside of the supporting dyeing tank 1.

[0038] Working principle: When it is necessary to fix the position of the steel pipe 29 for painting, the operation of the telescopic cylinder 211 drives the telescopic rod 212 to extend and retract, thereby causing the sliding block 22 to slide. This causes the rotating connecting rod 24 on the supporting rotating column 23 on both sides of the sliding block 22 to rotate, thereby causing the connecting rotating block 26 supported by the supporting connecting column 25 to rotate. This causes the clamping fixing ring 27 to move inward, thereby fixing the connecting ring 28 and the steel pipe 29 for painting. At the same time, the transmission mechanism 3 drives the clamping mechanism 2 to rotate, thereby causing the steel pipe 29 for painting to rotate. This achieves the effect of rotating the paint, which can increase the uniformity of the paint. Then it can be placed on the supporting dyeing tank 1 for drying.

[0039] The dried painted steel pipe 29 is placed on the second supporting rotating column 36, and then the clamping mechanism 2 clamps and fixes it again, so that it can rotate together with the third rotating pulley 35. Then, the rotation of the rotating motor 31 drives the rotation of the first rotating pulley 32, which in turn drives the rotation of the first rotating track 33 and the second rotating pulley 34, which in turn drives the rotation of the second supporting rotating column 36, which in turn drives the rotation of the third rotating pulley 35 and the second rotating track 37, which in turn drives the rotation of the fourth rotating pulley 38, thus achieving the effect of rotation. At the same time, the external connection of the first rotating pulley 32 is fixedly connected to the supporting column 39, which then drives the rotation of the painting sponge 310, thereby achieving the effect of painting the white painted steel pipe 29 with red paint again, thus achieving the effect of red and white alternating.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
