The invention discloses an electric locomotive group vehicle braking device with a braking relieving mechanism. The electric locomotive group vehicle braking device comprises a vehicle bottom plate, a braking mechanism and the braking relieving mechanism, wherein the braking relieving mechanism comprises a hand wheel, a worm rod shaft, a cam, a cam left half shaft and a cam right half shaft; the worm rod shaft is fixed on the vehicle bottom plate through a worm rod support; the cam left half shaft is fixed on the vehicle bottom plate by a cam shaft support; the cam left half shaft is supported on a braking mechanism; the right end of the cam right half shaft is provided with a worm wheel; the worm wheel is engaged with a worm rod on the worm rod shaft; the left end of the cam right half shaft is provided with a mutually-embedding type clutch movable section in a sliding manner; the right end of the cam right half shaft is provided with a mutually-embedding type clutch fixed section; the clutch fixed section is matched with the clutch movable section; the cam is mounted at the left end of the cam left half shaft. According to the electric locomotive group vehicle braking device, the braking is manually relieved under the condition of no air source, and the braking can be relieved when functional vehicles are independently parked; the electric locomotive group vehicle braking device is convenient to move, and the braking reliving is removed when the device is matched with an electric locomotive and the braking is recovered in a parking process.
