Device and method for controlling lifting and lowering bow of rail vehicle

Abstract

The present invention relates to the technical field of rail transit, and provides a rail vehicle running lift bow control device and method, the device comprising: bow lift solenoid valve, air filter, bow lift throttle valve, precision pressure regulating valve, bow lift throttle valve , three-way joint, lowering bow solenoid valve, safety valve; among them, the lifting bow solenoid valve is connected with the air filter, the air filter is connected with one end of the lifting bow throttle valve, and the other end of the lifting bow throttle valve is connected with the precision One end of the pressure regulating valve is connected, the other end of the precision pressure regulating valve is connected with the lower bow throttle valve, the lower bow throttle valve is connected with the first end of the three-way joint, the second end of the three-way joint is connected with the safety valve, and the three-way joint The third head is connected to the bow-lowering solenoid valve. The control device and method for raising and lowering the bow of rail vehicles provided by the embodiments of the present invention, through the selection of the bow-lowering solenoid valve, can not only realize the control of the conventional pantograph raising and lowering process, but also can control the bow-lowering process of the conventional pantograph. The situation realizes the control of the rapid bow-down process, and has 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...
