The invention discloses a winch braking device in the field of brakes. The winch braking device comprises a transmission shaft and a braking wheel, and further comprises a first retainer fixedly connected to the transmission shaft, and the size of the first retainer is smaller than that of the braking wheel. The transmission shaft is movably sleeved with the braking wheel, a second retainer is arranged on the side face of the braking wheel, and the first retainer and the second retainer can act in cooperation with the braking wheel. The braking wheel with large mass and inertia is separated from the transmission shaft, so that the transmission shaft does not need to provide power for the rotation of the braking wheel, energy consumption is reduced, and the problem that in the prior art, energy consumption on the braking device is high is solved.
