The invention relates to a freight train empty and load grading adjustment device and adjustment method, and the device comprises an empty and load adjustment module which is used for achieving the multistage adjustment and control of the braking force of an empty and load according to the received air pressure provided by an air pressure supply module; an air pressure supply module which comprises a plurality of cascaded additional air cylinders and is used for providing air with different air pressure levels; an air pressure adjusting module which is used for achieving communication betweenthe corresponding additional air cylinder and the empty and loaded vehicle adjusting module by controlling on-off of an electromagnetic valve; and an electronic control module which is used for controlling on-off of the electromagnetic valve according to the current load condition of the carriage. Compared with the prior art, an original automatic air braking system of the freight train is utilized, empty and load adjustment of the freight train is achieved through weak current control, the system adapts to existing hybrid power adjustment of long and large freight vehicles and vehicles with different loads, an existing braking control mode cannot be greatly changed, and the system is suitable for reconstructing a current freight system; the freight train empty and load grading adjustmentdevice has the advantages of strong adaptability, simple operation, reliable performance and the like.
本发明涉及一种货运列车空重车分级调整装置及调整方法,该装置包括:空重车调整模块:用于根据接收到气压供给模块提供的空气压力,实现空重车制动力的多级调控;气压供给模块:包括多个级联的附加风缸,用以提供不同气压级的空气;气压调节模块:用以通过控制电磁阀的通断实现对应的附加风缸与空重车调整模块的连通;电子控制模块:用以根据当前车厢的载重情况控制电磁阀的通断。与现有技术相比,本发明利用原有货运列车自动式空气制动系统,利用弱电控制实现货运列车空重车的调整,适应现有长大货运、不同荷载车辆混编制动力调整,不会大幅改变现有的制动控制模式,适合对当前的货运系统进行改造,具有适应性强、操作简便、性能可靠等优点。
