Description

technical field [0001] The utility model relates to an electro-pneumatic brake quick-filling device for supplementing compressed air, which relates to the technical field of vehicle brake relief. Background technique [0002] my country's railway network spreads all over the country, and railway passenger transport is the mainstream means of transportation. [0003] During my country's railway operation, at 4:41 on April 28, 2008, the downlink Beijing-Qingdao passenger train T195 derailed between Wangcun and Zhoucun on the Jiaoji Line and rushed to the outside of the uplink base. At this time, the normal operation of the 5034 passenger train from Yantai to Xuzhou failed to brake enough, and finally collided with the derailed vehicle at a speed of 70 kilometers per hour, and the locomotive and the 1st to 5th carriages derailed. The Jiaoji railway train collision accident has caused 72 deaths and 416 injuries. [0004] Therefore, the train braking response time is short, and...

Problems solved by technology

[0007] But, the deficiency of this brake machine of prior art is: when the train is running normally, the filling or exhausting of the brake main pipe is controlled by the locomotive, and when the brake main pipe is filled with wind, the compressed air will be distributed through each vehicle. Valves / control valves flow to the pressure and auxiliary cylinders of this vehicle

However, since each vehicle is only controlled by electric signals when the electro-pneumatic brake is charged, the main wind source required in the process of charging the air is still provided by the locomotive, and the role of the air cylinder is only for the purpose of cooperating with the electro-pneumatic brake. To ensure the consistency of the relief of the whole train, even if the relief cylinder is added, under the control of the electric signal, the auxiliary cylinder and the pressure cylinder of each vehicle can start to fill the air almost at the same time, but the capacity of the relief cylinder is small and The maximum pressure will not exceed the constant pressure of the brake main pipe, and it will only provide a small amount of wind for the brake main pipe. Most of the wind still needs to be provided by the locomotive, and the air filling time cannot be effectively shortened.

[0013] It can be seen that no matter whether it is an automatic air brake or an electro-pneumatic brake, after a relief, the pressure in the auxiliary air cylinder fails to return to the standard value in a short period of time, and the brake cannot be applied when braking is required. Cylinders provide enough compressed air that the brakes don't produce enough braking force, or even no braking effect at all
