Description

Technical Field

[0001] The utility model belongs to the technical field of subway track equipment, and in particular relates to a track transport vehicle for cleaning subway tracks. Background Art

[0002] With the increasing demand for travel, subways came into being. During the construction of subways, it is necessary to lay tracks for the movement of subways. Dust and impurities will be generated during the construction of existing tracks, which will reduce the construction quality of the rails. Therefore, it is necessary to clean the tracks.

[0003] The traditional way of workers cleaning tracks with handheld cleaning tools has high labor intensity and low cleaning efficiency. Cleaning tools and garbage generated by cleaning are also inconvenient to transport. Therefore, transport vehicles are currently used to carry workers, cleaning tools and garbage. Existing transport vehicles can be moved and transported through the equipped tracks, but cleaning tools and garbage are prone to fall from the transport vehicles during transportation, affecting the normal progress of the cleaning work. At the same time, after the cleaning work is completed, if the garbage is large and heavy, it is difficult to transport the garbage to a centralized processing area. For this reason, we propose a rail transport vehicle for subway track cleaning. Utility Model Content
