(3) Patent application number CN201821849689.5 publication number CN209697238U discloses "a petrochemical pipeline paint spraying apparatus", relates to paint spraying apparatus technical field, specifically is a petrochemical pipeline paint spraying apparatus, which comprises a body, the surface swing joint of body has the depression bar, the top fixedly connected with of depression bar presses the handle, and the other end has the briquetting, through the setting of rotating the handle, rotates the handle and drives the main tooth rotation during the use, and the driving gear drives the secondary and moves the gear, not only has effectually in the aspect of rust cleaning, again has effectually in the aspect of the paint spraying, but the device equipment is great, can't realize quick mopping to the pipeline paint spraying, consequently is not applicable to the use of the large scale pipeline paint spraying in colliery in the pit, but can reference this technique in the aspect of rust cleaning technical development.

Disclosure of Invention

The utility model aims to provide a portable rapid paint spraying device for underground coal mine pipelines, which has the advantages of small volume and mass, multiple functions, adjustability, good spraying effect and the like, is applicable to the existing pipelines in use in mines, and is a device which is popularized and used in the field of coal mine industry.

The technical scheme adopted by the utility model is that the portable rapid paint spraying device for the underground coal mine pipeline comprises a paint storage tank, a pressure regulating valve, a positive pressure meter and a paint conveying pipe, wherein the positive pressure meter is arranged on the paint storage tank, the positive pressure meter is connected with a pressure air pipe through the pressure regulating valve, and the pressure air pipe is communicated with the underground coal mine pipeline through a control valve; the paint conveying pipe stretch into the paint storage tank, the paint conveying pipe is divided into two, two ends of the paint conveying pipe are respectively extended to a C-shaped adjusting clamp, atomizing spray heads are respectively arranged on the pipe body of the paint conveying pipe on the C-shaped adjusting clamp at intervals, and a holding handle is arranged on the back face of the C-shaped adjusting clamp.

The utility model uses the principle of paint spray gun and the underground air pressure device to realize the purpose of quick paint spraying to the pipeline by using the advantage of adjusting the air pressure. The specific manufacturing method comprises the following steps: c-shaped adjusting buckle. Thin steel strips are selected for processing to manufacture U-shaped channel steel, the width is 3cm, the length is 50cm, and the U-shaped channel steel is two sections. The two sections of U-shaped channel steel are heated and bent to manufacture two sections of U-shaped channel steel with radian 60, the U-shaped channel steel is used as a main body of the buckle, and two ends of the U-shaped channel steel are plugged, so that tight air leakage is guaranteed. The front surface of the U-shaped channel steel is plugged by adopting a thin steel belt, a joint of 1cm is reserved on the surface of each section of thin steel belt, then an atomization spray nozzle is arranged in the front surface of the thin steel belt, and 6 atomization spray nozzles are reserved on each section of U-shaped channel steel. And (3) processing fixing screws at the bottoms of the two U-shaped channel steel sections after the manufacture, and connecting the two U-shaped channel steel sections (at the moment, the diameter is required to be approximately designed according to the pre-spray pipe channel specification). The two sections of U-shaped channel steel are combined in a crossing mode, the U-shaped channel steel is in a clamping fixture mode, the clamping model is primarily completed in the step, and the assembly is used as an adjustable device of the spray head. The coal mine underground full-section spray head used by the spray nozzle is required to be adjusted in the use process of the coal mine underground full-section spray head, the size of an opening and a sprayed material body of the spray head are required to be adjusted, the coal mine underground full-section spray head is installed in an annular adjusting bayonet after the adjustment is completed, and a paint conveying pipe of the materialized spray nozzle is communicated with a spray storage tank. The reason for selecting the wear-resistant anti-seismic positive pressure gauge for the mine is that the pressure in the paint spraying system is unstable due to unstable wind pressure in underground construction of the coal mine, so that the wear-resistant anti-seismic pressure gauge can be better used for controlling the pressure during paint spraying work, and the pressure control is more guaranteed.
