Description

orbital convection type intelligence of unilateral sweeps system

Technical Field

The utility model belongs to the technical field of the rail transit vehicle sweeps, concretely relates to orbital convection type intelligence system of sweeping of unilateral.

background

With the rapid development of national economy, people go out and travel more and more frequently, and the requirements on the rapidness and convenience of service are higher and higher. In order to adapt to and promote the development of the industry, the rail transit is developed in a blowout mode as a novel traffic mode. Correspondingly, higher requirements are put on the operation and maintenance safety of the rail transit vehicle.

in the running process of the rail transit vehicle, because the friction between the wheels and the rails can generate a lot of dust, the dust is adsorbed on the surface of the electric equipment at the bottom of the train to cause some electric faults, the top and the bottom of the train body are required to be removed regularly and timely in order to ensure the running safety of the vehicle, if the dust is not removed in time, the vehicle performance and the service life are influenced, and the vehicle faults can be caused in serious conditions to cause traffic accidents.

At present, the sweeping operation of the electric parts at the bottom of the vehicle in the railway transportation vehicle maintenance place in China is mainly completed by manually cleaning or automatically sweeping by a mechanical arm in combination with manual repair. When the type of the vehicle to be purged and the marshalling length are changed, the traveling path of the AGV trolley cannot be expanded and changed rapidly in time, and the requirement of purging operation cannot be met.
