Problems solved by technology

When the locomotive needs to start the backup brake, the operator needs to put the handle of the backup brake valve in the braking position first, and the braking effect will be produced after a period of time. In the case of long train formation, the lag of the backup brake is particularly Obviously, the hysteresis of the braking effect will make it inconvenient for the driver to operate, and it is easy to cause accidents during the hysteresis

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.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a backup braking device for a locomotive. The invention also relates to a locomotive comprising the above-mentioned backup braking device. Background technique [0002] At present, in order to enable the rail vehicle to effectively brake when a breakdown occurs and prevent accidents, a backup brake device is generally provided in the locomotive, and the backup brake releases the pressure of the train pipe to realize the brake of the locomotive. When the locomotive needs to start the backup brake, the operator needs to put the handle of the backup brake valve in the braking position first, and the braking effect will be produced after a period of time. In the case of long train formation, the lag of the backup brake is particularly Obviously, the hysteresis of the braking effect will make the driver's operation inconvenient, and it is easy to cause accidents during the hyst...
