Description

Technical Field

[0001] The utility model relates to the technical field of intelligent rail train cleaning equipment, in particular to a vehicle outer skin cleaning system suitable for intelligent rail trains. Background Technique

[0002] The intelligent rail rapid transit system ART (Autonomous rail Rapid Transit) is a new type of rail transit system with the dual attributes of urban rail transit and ground public transportation. It uses intelligent rail trams as the carrier, and has the advantages of short construction period, small infrastructure investment, high urban adaptability, strong comprehensive transport capacity, etc. Compared with other traditional rail transit systems such as modern tramways, intelligent rail trams do not need to lay physical tracks, and only need simple road painting to put into use, which not only greatly reduces the construction volume, but also avoids additional projects such as bridge reconstruction and line demolition, and has less impact on the existing urban environment. Due to the use of rubber wheels driven by permanent magnet motors, the climbing ability of intelligent rail trams is as high as 13%, which is 7% higher than that of traditional tramways.

[0003] The cleaning of the train outer skin is one of the important processes before entering the depot for maintenance. At present, whether it is EMUs or urban rail transit vehicles, the domestic cleaning processes at present are mostly: high-pressure water jet, brushing, manual cleaning, etc. This traditional cleaning method can ensure the cleaning quality, but the operation time is long, the labor intensity is large, it occupies a lot of human resources, and the cleaning quality of subways and EMUs is mostly at night and is affected by the state of the operators.

[0004] There are also some areas that use car washers to clean the outer skin of rail vehicles. At present, the car washers use multiple sets of washing units fixed on both sides of the track. After the train enters the depot, the water spraying device first operates to conduct high-pressure flushing on the vehicle body, and then the washing units start to operate. This process relies on the movement of the train to achieve the cleaning of the vehicle outer skin. This method requires multiple sets of washing units and the washing area is limited.

[0005] At present, the maintenance process of intelligent rail trains has not been clarified. Due to the lack of operation experience, the existing cleaning methods mostly use manual cleaning, with long car wash time, low efficiency and large workload. Intelligent rail trains use rubber wheels for bearing. If still referring to the traditional steel wheel and steel rail trains and adopting the passing car wash method with a fixed car wash machine for the moving vehicle, its driving deviation may hit the brush, causing damage to the car wash equipment. Therefore, it is necessary to develop a vehicle outer skin cleaning system suitable for intelligent rail trains to shorten the cleaning time of intelligent rail trains and improve the maintenance efficiency.
