Embodiment 1
[0032] Such as figure 1 and figure 2 Commonly shown, this embodiment provides a railway vehicle slippage braking system, including a main control subsystem and a braking subsystem, and the main control subsystem and the braking subsystem are connected in communication;
[0033] The braking subsystem is used to brake the slippage of the vehicle passing the stopper on the railway track based on the anti-slip iron shoes controlled by the cascade relay interlock according to the vehicle information. The braking subsystem automatically detects the slippage of the vehicle conditions and models, and automatically perform slip braking, which avoids safety accidents caused by manual judgment and improves safety;
[0034] The main control subsystem is used to monitor the working conditions of the braking subsystem and generate control signals to uniformly control the braking subsystem. The control subsystem conducts unified management and monitoring of the braking subsystem, which imp...

The invention belongs to the technical field of railway braking, and discloses a railway vehicle runaway braking system which comprises a main control subsystem and a braking subsystem which are in communication connection. The braking subsystem is used for carrying out runaway braking on a vehicle exceeding a parking device on a railway track based on an iron shoe structure in cascade relay connection according to the vehicle information; and the main control subsystem is used for monitoring the working condition of the braking subsystem and generating a control signal to uniformly control the braking subsystem. The problems that in the prior art, an independently-arranged anti-slip iron shoe is low in anti-slip effect, low in timeliness of a manual mode, low in action efficiency and low in safety are solved.
Description
technical field [0001] The invention belongs to the technical field of railway braking, and in particular relates to a slippage braking system for railway vehicles. Background technique [0002] At present, the domestic railway marshalling yards mainly use "2+1" parking devices as the main means to prevent vehicles from slipping away, which solves the problems of tail parking and anti-slipping to a certain extent, but there are two outstanding problems. The potential safety hazard that vehicle flows out of parking device; The 2nd, need to manually lower iron shoe, or the method auxiliary anti-slip of manual control upper and lower iron shoe. This mode of operation is labor-intensive, has high labor costs, and has certain potential safety hazards. How to effectively prevent vehicles from slipping away and ensure the safety of shunting operations at the rear of the marshalling yard is an important problem to be solved in the current research on railway braking. [0003] Ther...
