Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a high-efficiency painting device for steel pipes. Background Technology

[0002] Steel pipes are primarily composed of iron, which is prone to oxidation and rusting when exposed to air for extended periods. The main purpose of painting steel pipes is corrosion prevention, extending their service life, and enhancing their aesthetics and functionality. Painting effectively isolates the pipes from air and water, forming a protective layer that prevents contact between the pipes and moisture in the air, thus extending their lifespan. Painted steel pipes also have a more attractive appearance, and different colors can be used to distinguish uses or areas, improving work efficiency and safety.

[0003] However, most painting of scaffolding steel pipes and temporary protective steel pipes on the market is currently done manually, which has the following drawbacks: 1. High labor intensity: Manual painting requires a lot of physical labor. Workers need to hold tools for a long time, which can easily lead to fatigue and decreased efficiency. 2. Low work efficiency: Manual painting is slow and uneven, which cannot meet the needs of large-scale construction, resulting in extended construction period; 3. High processing costs: High labor costs and the need for more time and manpower to complete the work increase the overall cost of the project; 4. Pollutes the environment: Paint spills pollute the environment.

[0004] Therefore, we propose a high-efficiency painting device for steel pipes. Utility Model Content

[0022] This utility model proposes a high-efficiency painting device for steel pipes.

[0023] like Figures 1 to 5 As shown, in one embodiment of this utility model, the high-efficiency steel pipe painting device includes a paint tank 101, a paint coating roller 102, a drive shaft 103, a first gear 104, a second gear 105, and a drive motor (not shown). The paint tank 101 is a cuboid structure with an upper opening. The paint coating rollers 102 are arranged parallel and spaced apart in the paint tank 101. The two ends of the paint coating rollers 102 are rotatably connected to the two end side walls of the paint tank 101 through bearings. The drive shaft 103 is rotatably arranged on the side wall of one end of the paint tank 101 through bearings. The first gears 104 are respectively arranged at the same end of the paint coating rollers 102. The second gear 105 is arranged on the drive shaft 103 and is located in the middle of the two first gears 104. The second gear 105 is meshed with the first gear 104. The output shaft of the drive motor is connected to the drive shaft 103, and the drive motor drives the paint coating rollers 102 to rotate.

[0024] Specifically, it also includes a synchronous pulley (not shown) and a synchronous belt (not shown). The synchronous pulley is respectively mounted on the drive shaft 103 and the output shaft of the drive motor. The synchronous belt is respectively clamped on the synchronous pulley. The synchronous belt and the synchronous pulley are meshed and connected. The drive motor makes the drive shaft rotate through the synchronous belt and the synchronous pulley.

[0025] Specifically, it also includes a bracket 106, with a paint tank 101 disposed at the upper end of the bracket 106.

[0026] Specifically, it also includes partitions 107, which are arranged parallel to each other in the paint tank 101. The side walls and bottom walls of the partitions 107 abut against the inner side walls and bottom walls of the paint tank 101, respectively. The upper end of the partitions 107 is recessed with two U-shaped grooves 1071 that are adapted to the paint coating rollers 102. The paint coating rollers 102 are rotatably embedded in the U-shaped grooves 1071, and the outer peripheral wall of the paint coating rollers 102 slides against the inner peripheral wall of the U-shaped grooves 1071. The two adjacent partitions enclose a paint area, and different colors of paint can be added to the paint area as needed, so that multiple different colors of paint can be applied to the outer peripheral wall of the steel pipe at one time.

[0027] Specifically, the bottom of the paint tank 101 is provided with a paint collection port (not shown), and the paint collection port is detachably provided with a soft rubber plug to facilitate the recycling of remaining paint.

[0028] Specifically, the lower end of the bracket 106 is provided with multiple adjustable support feet 1061, which facilitates the adjustment of the bracket height and has wide adaptability.

[0029] Specifically, the paint coating roller 102 is formed from stainless steel, aluminum alloy or hard alloy ceramic powder.

[0030] Specifically, the outer peripheral wall of the paint coating roller 102 is provided with a wear-resistant coating 1021, and the thickness of the wear-resistant coating 1021 is greater than 0.25 mm. The wear-resistant coating effectively improves the wear resistance and corrosion resistance of the paint coating roller, thereby extending the service life of the paint coating roller.

[0031] Specifically, the wear-resistant coating includes a nickel-chromium alloy coating 10211 and a ceramic coating 10212. The nickel-chromium alloy coating 10211 is applied to the outer peripheral wall of the paint coating roller 102 using plasma spraying technology, and the ceramic coating 10212 is applied to the outer peripheral wall of the nickel-chromium alloy coating 10211 using plasma spraying technology. Plasma spraying technology uses a plasma arc driven by direct current as a heat source to heat materials such as ceramics, alloys, and metals to a molten or semi-molten state, and then sprays them at high speed onto the pre-treated workpiece surface to form a firmly adhered surface layer. This method gives the paint coating roller surface wear resistance, corrosion resistance, and high-temperature oxidation resistance, effectively improving the wear resistance and corrosion resistance of the paint coating roller, thereby extending its service life.

[0032] Specifically, the porosity of the ceramic coating 1022 ranges from 1% to 2%. The porosity of a ceramic coating refers to the volume percentage of pores in the coating. Excessive porosity reduces the coating's density and corrosion resistance, while insufficient porosity may affect its toughness and thermal shock resistance. Preferably, in this embodiment, the porosity of the ceramic coating 1022 is 1.5%. A porosity of 1.5% optimizes the adhesion of paint and coatings.

[0033] The working principle and process of this utility model are as follows: First, paint is poured into the paint tank, and the lower end of the paint coating roller is immersed in the paint. Then, the steel pipe 200 is placed between the two paint coating rollers, abutting against the outer circumference of the paint coating rollers. The drive motor is started, which drives the paint coating rollers to rotate. The paint coating rollers then drive the upper end of the steel pipe to rotate automatically, thereby achieving uniform paint coating on the outer circumference of the steel pipe. This effectively improves the efficiency of painting the outer circumference of the steel pipe, reduces labor costs, improves the uniformity of paint coating on the outer circumference of the steel pipe, and improves the painting quality. Moreover, the operation is simple and convenient, and it can effectively solve the problems of low painting efficiency, poor paint uniformity, and paint spillage polluting the environment of guardrail steel pipes. It is highly practical. The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
