Automatic brake for train running off rails

Abstract

An automatic brake for preventing a train from being turned over when the train is derailed features that its main body is a blind air tube made of the fragile material, installed to the steering bogie and connected with the air tube of train. When the train is derailed, the blind air tube is broken by rail and the air is released, resulting in braking.

Description

Technical field: [0001] The invention relates to a device for ensuring the safety of train operation, which can automatically brake the train when it is derailed and prevent the train from overturning. Background technique: [0002] Train overturning accidents happen from time to time. Every time such an accident occurs, it will bring great losses to people's lives and property safety. The train derailment subversion accident is called the "cancer" of railway transportation. [0003] Practice has proved that before the train overturns, the wheelset falls off the rail at first, which is called derailment, and then the wheelset collides violently with the sleeper or other obstacles. When the impact reaches a certain level, an overturning accident will occur. [0004] At present, there is no effective method to stop the train in time at the moment of derailment. This is because the derailed compartment is likely not at the head and tail of the train, and the driver or the gu...

AI Technical Summary

Problems solved by technology

This is because the derailed car is probably not at the head and tail of the train, and at this time the driver or the guard at the rear of the train cannot find the derailed car in time and stop in time.
