Description

Technical Field

[0001] The utility model relates to the technical field of underground coal mine equipment, in particular to a special retractable pipeline painting device for coal mines. Background Art

[0002] The underground of coal mines is dark and humid. After a period of time, the paint on the surface of the compressed air pipelines, water supply pipelines and drainage pipelines laid in the gateways will fade and rust seriously. As the working face advances forward, after the removed iron pipes are transported out of the well, the pipes are usually painted manually. Since manual painting has a high labor intensity, low efficiency, uneven painting affecting the appearance, and workers are exposed to substances such as paint and thinner for a long time, it will cause great harm to the respiratory system of workers. After painting, the pipelines need to be manually removed and transported to a suitable place for drying, and the dismantling and transportation process may also damage the unpainted surface, further increasing the labor intensity of workers. Existing automatic painting devices occupy a large area in the machine repair workshop, and the slender body is very easy to trip and injure the working workers, affecting work efficiency and bringing certain impacts to work safety.
