Hand mechanism of hoist formula headstock gear

The utility model discloses a hand mechanism of hoist formula headstock gear belongs to hoist formula headstock gear gate drive device technical field. Its technical scheme does: a hand mechanism of hoist formula headstock gear, wherein includes the casing, sets up driving shaft and driven shaft in the casing, follows the driving shaft axial is equipped with rather than fixed friction disk in proper order, ratchet and gear I, the driving shaft stretches out the tip in the casing outside is equipped with the crank. The beneficial effects of the utility model are that: through rotating the rocking arm, gear I and ratchet counter -clockwise turning, gear I pass through the internal thread and rotate near friction disk and locking, and stability is high, has realized accomplishing under the condition of power failure the rising and the decline of gate.
