Problems solved by technology

[0002] When the locomotive is in the no-fire loopback mode, it usually needs other vehicles to drag it. At this time, the operator needs to trigger the parking relief on the console. Apply the button to control the pulse. The solenoid valve is in the parking relief state. If the operator misoperates, there is no control pulse. If the solenoid valve is in the response state, there is no pressure input in the parking brake cylinder, and its relief cannot be guaranteed, so that the locomotive cannot be returned without fire.
In the prior art, another situation that usually occurs is that the pulse solenoid valve fails or the power supply for the pulse solenoid valve is in a state of no power supply, and the operator cannot control the state of the pulse solenoid valve, so that the locomotive cannot perform fire-free return

Abstract

The application discloses a parking brake control unit with a remote release function. The parking brake control unit comprises a first cock arranged on a pipeline and used for being communicated with a main air duct, a second cock used for being communicated with a brake pipe, and a third cock used for being communicated with an average pipe, and further comprises a pulse solenoid valve arranged on the pipeline and used for being communicated with a parking brake cylinder, wherein the first cock and the second cock are communicated with the pulse solenoid valve; the pulse solenoid valve comprises a pilot control terminal used for controlling the status of the pulse solenoid valve according to pressure input; the second cock is further communicated with the pilot control terminal of the pulse solenoid valve.

Description

technical field [0001] The present application relates to a parking brake control unit with remote release function. Background technique [0002] When the locomotive is in the no-fire loopback mode, it usually needs other vehicles to drag it. At this time, the operator needs to trigger the parking relief on the console. Apply the button to control the pulse. The solenoid valve is in the parking relief state. If the operator misoperates, there is no control pulse. If the solenoid valve is in a responsive state, there is no pressure input in the parking brake cylinder, and its relief cannot be guaranteed, so that the locomotive cannot be returned without fire. In the prior art, another situation that usually occurs is that the pulse solenoid valve fails or the power supply for the pulse solenoid valve is in a state of no power supply, and the operator cannot control the state of the pulse solenoid valve, so that the locomotive cannot perform fire-free return .
