Mitigation device for locomotive parking brake

The invention provides a mitigation device for a locomotive parking brake. The mitigation device for the locomotive parking brake comprises a hand pulling rod arranged transversely. A second support stopping piece is arranged on the peripheral surface of the hand pulling rod. The second support stopping piece is fixedly connected with the hand pulling rod. The second support stopping piece is provided with a lateral push-out assembly in the lateral side direction. The lateral push-out assembly is in contact with the second support stopping piece. The lateral push-out assembly is connected with a drive member capable of driving the lateral push-out assembly to drive the second support stopping piece to move in the lateral single direction. The drive member is located on the side of the hand pulling rod in the vertical direction. The mitigation device for the locomotive parking brake can improve the flexibility and the working efficiency of a locomotive during the parking brake mitigation operation process. 本发明
