Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a pipeline painting device and method thereof. Background Art

[0002] Currently, during the building construction process, pipelines such as fire protection, sprinkler, and heating pipelines are all painted on the outer layer of the pipeline for pipeline anti-corrosion, and at the same time, functions such as aesthetics are achieved.

[0003] Pipeline painting can form a protective coating on the pipeline surface, preventing the metal pipeline from coming into direct contact with water, oxygen, and chemical substances in the external environment, thereby reducing the risk of corrosion. This is very important for the long-term service life and performance of the pipeline. When the pipeline is exposed to the air, it may be affected by oxidation.

[0004] Painting can form a barrier to reduce the oxidation of the pipeline surface, thereby maintaining the surface quality and performance of the pipeline. In some specific applications, the pipeline may need to come into frequent contact with other surfaces or objects. Applying an appropriate lubricating paint can reduce the friction between the pipeline and other objects, thereby reducing wear and damage.

[0005] Painting the pipeline with different colors of paint can be used to identify pipelines of different types, uses, or contents, thereby improving the visibility and safety of the pipeline system.

[0006] In some industrial environments, the pipeline may need to handle high-temperature or low-temperature liquids or gases. The coating can help the pipeline surface maintain a relatively stable temperature, thereby improving the working efficiency and safety of the pipeline.

[0007] Painting can improve the appearance of the pipeline, making it look cleaner and more beautiful. This is particularly important in public places, inside buildings, etc. where a good visual effect is required.

[0008] Generally speaking, pipeline painting plays an important role in maintaining pipeline performance, extending the service life, improving safety, and enhancing the appearance.

[0009] However, during the painting process, a large amount of toxic and harmful dust is generated, seriously affecting the physical health of the operators and also causing serious pollution to the surrounding environment; when manually painting the pipeline, it is necessary to bend down for a long time. Prolonged bending will lead to the occurrence of occupational diseases among workers, and the work efficiency will also become slower and slower. Secondly, due to different numbers of painting times and the amount of paint dipped each time by the brush, the pipeline paint is unevenly applied, so the painting quality cannot be guaranteed. The cost of using operators with mature technology is relatively high, and the quality cannot be guaranteed if ordinary operators are hired. Finally, after the pipeline is painted, it needs to be left to dry naturally until the paint dries, which is a waste of time.

[0010] The information disclosed in this background section is only intended to enhance the overall understanding of the background of the present invention and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art.

[0074] S3. The two clamps 33 of the clamping structure 3 clamp the pipeline 7 on the bracket 2.

[0075] S4. The bearing platform 32 of the clamping structure 3 rises, and at the same time, the driving member of the clamping structure 3 drives the clamp 33 to rotate to drive the pipeline 7 to rotate.

[0076] S5. The paint nozzle 4 is aligned with the pipeline 7 to spray paint, and at the same time, the second sliding seat 42 moves along the second guide rail 41, so that the paint is coated on the pipeline 7 section by section.

[0077] S6. After the paint of the pipeline 7 is sprayed, the bearing platform 32 descends, and at the same time, the clamping structure 3 releases the pipeline 7 to place the pipeline 7 on the bracket 2.

[0078] S7. The bracket 2 is pushed into another protective box 1, and the drying device 5 is turned on to dry the pipeline 7. When drying the pipeline 7 and spraying the pipeline 7, the suction air duct 61 of the purification device 6 sucks the gas in the protective box 1 and discharges it into the absorbent liquid in the liquid storage tank 62 of the purification device 6, so that the toxic and harmful substances in the gas are absorbed by the absorbent liquid and the discharged gas meets the emission standards.

The pipeline painting equipment of the present invention fixes the pipeline to be painted in a protective box through the clamping structure, drives the pipeline to rotate through the driving member, and controls the rotation speed of the pipeline by adjusting the speed. The paint is pumped from the paint bucket through the paint nozzle by a small pump and sprayed out to spray the paint on the pipeline. At the same time, the paint nozzle moves uniformly along the second guide rail driven by the second sliding seat, sprays the paint on the rotating pipeline, and adjusts the rotation speed of the pipeline and the moving speed of the nozzle to control the painting thickness.

[0080] During the paint spraying process, the suction air duct (exhaust fan) is started to discharge the gas during the paint spraying process through the suction air duct to the liquid storage tank containing the absorbent, and the waste gas during the pipeline painting process is absorbed and treated. After absorption, the purified gas is discharged with the assistance of a small fan. After painting, the drying device can be turned on to dry the paint on the painted pipeline.

[0081] The telescopic ceiling can ensure that the paint will not splash everywhere during the paint spraying process and concentrate the gas during the spraying process, and discharge it to the liquid storage tank containing the absorbent through the exhaust fan and the suction air duct.
