Abstract:
A backup brake device for a locomotive, comprising a backup brake relay valve (2) connected to a brake pipe, and a backup brake valve (1) connected to the backup brake relay valve (2) by means of a backup main pipe (4), a pressure relief air cylinder (7) being connected to the backup brake valve (1) in parallel, a control device being provided between the pressure relief air cylinder (7) and the backup main pipe (4) for controlling the connection and disconnection therebetween. After the backup brake valve (1) is opened, the backup brake device can connect the backup main pipe (4) with the pressure relief air cylinder (7), so that the backup main pipe (4) relieves pressure both to the atmosphere and to the pressure relief air cylinder (7), thereby reducing the time delay of brake and reducing risk of accidents.
