Rust-removing device for surface of mine wind and water pipeline

Abstract

The invention discloses a surface derusting device for a mine-used air-water pipeline, which comprises a bottom plate, a first telescopic rod is arranged on the upper side of the bottom plate, a connecting plate is arranged on the upper side of the first telescopic rod, and a first connecting rod is arranged on the left side of the connecting plate. There is a handle on the left side of the connecting rod, a connecting groove on the right side of the connecting plate, a screw rod inside the connecting groove, connecting sleeves at the upper and lower ends of the screw rod, and a third connecting rod on the right side of the connecting sleeve. The right side of the connecting rod is provided with a fixed block, the right side of the fixed block is provided with a semi-circular cover, the inside of the semi-circular cover is provided with a connecting cavity, the inside of the connecting cavity is provided with a second telescopic rod, the lower end of the second telescopic rod is provided with a semicircular sliding arc plate, and the semicircular sliding Ring-shaped bevel teeth are arranged at the front and rear ends of the arc plate, bevel gears are arranged at the outer upper end of the ring-shaped bevel teeth, a rotating shaft is arranged at the inner upper end of the bevel gear, and a motor is arranged at the upper end of the rotating shaft. The invention can effectively remove the rust on the surface of the installed geomantic pipe, thus effectively improving the working efficiency of the equipment and saving manpower and material resources.

Description

technical field [0001] The invention relates to the field of mineral products, in particular to a rust removal device for the surface of a mine-used wind and water pipeline. Background technique [0002] A coal mine refers to a place rich in coal resources, and usually refers to a factory that produces coal by underground or open-pit mining. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in China are underground coal mines. Coal mines include large areas above and below ground and associated facilities.

Problems solved by technology

[0003] In order to provide wind and water to various production sites underground, it is often necessary to use Feng Shui pipes to supply air and water. However, because Feng Shui pipes are fixedly installed inside each mine, such long-term corrosion will lead to loopholes in the pipes, so that There will be water leakage and air leakage, which will affect production. Therefore, underground workers often need to paint the surface of the Feng Shui pipeline after derusting, which is used to slow down the corrosion of the pipeline surface and increase the service life of the pipeline. But now The rust removal of the pipeline after installation is generally done by manually wiping the surface of the pipeline with sandpaper or cotton yarn. This method not only wastes manpower and material resources, but also has a particularly low work efficiency.
