Abstract

The invention discloses an air stand-by brake system and brake method. The air stand-by brake system comprises a brake controller, an equalizing reservoir, a relay valve, an input valve and a throttle valve; the air stand-by brake system is connected with an original train pipe of a locomotive through the input valve, and connected with an original main blast line of the locomotive through the throttle valve; if a main brake control system is power-off, the input valve is used for being opened to a switch-on position, so that an air channel is communicated; the brake controller is used for controlling the pressurization and depressurization of the equalizing reservoir; the equalizing reservoir is used for taking the pressure of the equalizing reservoir as the pilot pressure of the relay valve; and the relay valve is used for controlling the pressure change of the train pipe according to the pressure change of the equalizing reservoir, wherein the pressure of the equalizing reservoir and the pressure of the train pipe are in a synchronous state. According to the embodiment of the invention, the brake function of the locomotive can be ensured, so that the locomotive can continue to run and maintain to a locomotive depot, and then is maintained, in such a way, the locomotive does not stop on a trunk railway for a long tine, thereby reducing the effect on the order of a railway.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric locomotives, in particular to an air backup braking system and a braking method. Background technique [0002] With the continuous growth of railway traffic and frequent occurrence of various railway safety accidents, the railway safety operation management department has higher and higher requirements for the safety of locomotives. How to improve the safety performance of locomotives has become the top priority of all locomotive manufacturers. Heavy. [0003] The main braking methods used in the locomotives in the prior art are electric braking and air braking, and the air braking is still the main braking method, so the requirements for it must not be compromised. The Harmony series locomotive brake controller is an electronic control device. When it has an electrical failure, it loses the braking control function of the locomotive. Although the emergency braking function...
