Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal device for railway tunnel construction. Background Technique

[0002] A railway tunnel is a dedicated passage for train transportation. When a railway passes through mountainous areas, due to limited traction capacity and maximum gradient requirements, it is necessary to overcome elevation obstacles. Digging a tunnel through mountains is a reasonable choice. Its functions are to shorten the line, reduce the gradient, improve operating conditions, and increase traction capacity. According to its location, it can be divided into three categories: mountain tunnels that pass through mountains or hills to shorten the distance and avoid large gradients; underwater tunnels that pass under rivers or through the seabed to cross rivers or straits; and urban tunnels that pass underground in cities to meet the needs of railways passing through large cities.

[0003] After retrieval, the patent number is CN220748324U, which discloses a dust removal device for railway tunnel construction. Although the existing dust removal devices for railway tunnel construction are powered by new energy, when used in the external environment of railway tunnels, it is inconvenient to charge them, and there are certain limitations in use; or usually, items such as water transportation pipes are directly placed or hung on the dust removal vehicle. When the dust removal device is moved, they are likely to fall off and be directly exposed to the outside, which easily leads to a reduction in the service life of the transportation pipes. However, when in use, dust removal is carried out through an atomizing cannon barrel, the dust removal efficiency is insufficient, and excessive spraying of water mist will cause all the dust washed by the water mist to stick to the bodies of the construction workers at the construction site, affecting the work experience of the workers.

[0004] Therefore, a dust removal device for railway tunnel construction is proposed. Content of the Utility Model
