The invention, which relates to the technical field of rail transit, provides a rail vehicle operation pantograph ascending and descending control device and method. The device comprises a pantographascending solenoid valve, an air filter, a pantograph ascending throttle valve, a precise pressure regulating valve, a pantograph descending throttle valve, a three-way joint, a pantograph descendingsolenoid valve and a safety valve. The pantographascendingsolenoid valve is connected with the air filter; the air filter is connected with one end of the pantograph ascending throttle valve, the other end of the pantograph ascending throttle valve is connected with one end of the precision pressure regulating valve, the other end of the precision pressure regulating valve is connected with the pantograph descending throttle valve, the pantograph descending throttle valve is connected with a first end of the three-way joint, a second end of the three-way joint is connected with the safety valve, and a third end of the three-way joint is connected with the pantograph descending solenoid valve. According to the control device and method, through selection of the pantograph descending solenoid valve, control over the conventional pantograph ascending and descending process can be achieved, control over the rapid pantograph descending process can be achieved according to the special situation that rapid pantograph descending is needed, and the control device and method have wider applicability.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to a control device for a rail vehicle running lifting bow. Background technique [0002] Electric traction trains need to lower the pantograph during operation. If a fault occurs during the operation of the train, it is necessary to change the bows; and if the AC rail vehicle running with double bows or even multiple bows does not meet the requirements of the phase separation area, it can choose to lower part of the pantographs before entering the phase separation area. , to ensure that the vehicle passes through the phase separation area safely. [0003] Some bow lowering operations when the train is running have specific requirements on the bow lowering speed. For example, the bow changing operation when the train fails, if the operation can be realized in a short time, the impact of the vehicle failure on the operation order can be greatly reduced, and passengers ca...
