Description
Technical Field
The invention belongs to the technical field of rail transit vehicle purging, and particularly relates to an intelligent purging system and method with an ultrasonic cleaning function based on electromagnetic guidance.
Background
Along with the rapid development of national economy, people travel and traffic are more frequent, and the requirements on rapidness and convenience of service are also higher. In order to adapt to and promote the development of the industry, rail transit presents blowout type development as a novel traffic mode. Accordingly, higher requirements are put on the safety of the operation and maintenance of rail transit vehicles.
In the running process of the rail transit vehicle, because a lot of dust can be generated due to friction between wheels and the rails, the dust is adsorbed on the surface of electric equipment at the bottom of a train to cause some electric faults, in order to ensure the running safety of the vehicle, the top and the bottom of the vehicle body are required to be timely dedusted regularly, if the dedusting is not timely carried out, the vehicle faults can be caused when serious except the influence on the performance and the service life of the vehicle, and traffic accidents are caused.
At present, the operation of purging electric parts at the bottom of a vehicle in a domestic rail transit vehicle maintenance place is mainly completed by means of manual cleaning or automatic purging through a mechanical arm and combining manual repairing. When the vehicle type to be purged and the grouping length are changed, the traveling path of the AGV cannot be quickly expanded and changed in time, so that the requirement of purging operation cannot be met.
At present, a simple purging station is arranged in a part of domestic railway traffic vehicle overhauling places, but only dust removal and purging are carried out on parts such as a bogie at the bottom of a vehicle. However, in the long-time actual operation process of the rail transit vehicle, a large amount of dust and dirt can be accumulated on the air conditioning filter screen at the top of the vehicle and the folds of the through channels, if the rail transit vehicle is purged irregularly, hidden dangers of electrical faults are caused, and the normal operation of the vehicle can be threatened.
At present, the purging operation of the overhauling places of the domestic rail transit vehicles is mostly manual blowing dust collection, the purging area is small, the purging efficiency is low, the thorough abnormal situation cannot be found, the labor intensity of purging operation personnel is high, and secondary pollution is caused by uncertainty of manual operation.
The existing dust absorption units are arrayed in the factory building, all the dust absorption units are uniformly controlled to be opened after the purging operation is started, and a large wind field is formed, but in the area without manual or mechanical arm operation, dust is not purged, the dust absorption effect of the dust absorption units is limited, a large amount of energy sources are wasted, and mechanical noise of rolling in the factory building is caused.
In addition, because equipment such as a bogie at the bottom of a vehicle is extremely irregular in distribution and shape, the flying path of dust generated during actual purging operation is also extremely irregular, and the purging station is difficult to form a relatively closed space in consideration of the requirement of vehicle limit, so that the dust is difficult to collect during purging operation.
