Rail transit vehicle bottom automatic purging system

Abstract

The invention discloses a rail transit vehicle bottom automatic purging system which comprises a moving trolley, a guide magnetic strip, a magnetic navigation sensor, a mechanical arm, an air gun, a fan and a power supply system, and the guide magnetic strip is installed in a trench; the magnetic navigation sensor is arranged on the moving trolley and is used for detecting a magnetic field generated by the guide magnetic strip so as to guide the moving trolley to walk in a trench; the mechanical arm is installed on the moving trolley, and the air gun is installed at the tail end of the mechanical arm so as to be used for purging the bottom of a vehicle. The fan is installed on the movable trolley and connected with the air gun through a hose. The power supply system comprises a vehicle-mounted power supply, and the vehicle-mounted power supply is connected with the fan so as to supply power to the fan. The rail transit vehicle bottom automatic purging system can blow air in all directions, and the vehicle bottom blowing efficiency and effect are improved while the labor intensity of workers is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transit vehicle maintenance, and more particularly relates to an automatic purging system for the bottom of rail transit vehicles. Background technique [0002] During the long-term operation of rail transit trains, it is easy to absorb or adhere to the dust on the track bed. The accumulated dirt for a long time will affect the operation of the equipment on the bottom of the vehicle, and then affect the safety of the train. Purging the bottom of the vehicle is an important part of the maintenance work of the train. Fast and efficient under-car purging is also the goal pursued by train maintenance work. [0003] At present, most of the cleaning of the bottom of the vehicle is to install fixed blowing equipment and pipelines next to the track columns. The operators use air guns and dust suction pipes to complete the cleaning of the bottom of the vehicle. Time-consuming, low efficiency, high labor inte...
