Invention thought of the present utility model is: for winch hoist operationally, if run into power failure, need the problem realizing gate rise and fall by other method, arranging hand-operated mechanism is connected on reductor driving shaft, travel switch is open in usual, works as driven by power, when namely hand-operated mechanism is in off working state, handwheel is extracted, and touches travel switch; During hand-operated mechanism work, inserted by handwheel, namely reductor shaft inserts hand-operated mechanism casing, is connected, promotes hand-operated mechanism counterclockwise with driven shaft, and gate rises; Otherwise gate declines.
A kind of winch hoist hand-operated mechanism, wherein, comprises casing, be arranged on the driving shaft in casing and driven shaft, axially be provided with the frictional disk fixing with it successively along described driving shaft, ratchet and gear I, the end that described driving shaft stretches out outside described casing is provided with crank;
Described driven shaft is provided with the gear II be meshed with described gear I, and an end of stretching out described casing at described driven shaft is plugged with handwheel, and the casing below described handwheel is provided with travel switch;
Casing inner wall below described driving shaft arranges bearing pin, described bearing pin is provided with the ratchet matched with described ratchet, is arranged with back-moving spring outside the bearing pin between described ratchet and described casing.
Driving shaft circumference between described gear I and casing arranges back-up ring, arranges lock-screw in the side of described back-up ring.
Itself and described driving shaft are fixed by straight pin by described frictional disk.
Described crank is by hollow cylindrical fixed cover, the rocking arm that one end is connected with described fixed cover, and is arranged on the handle of the described rocking arm other end.
Described fixed cover matches with described driving shaft, and its internal diameter is slightly larger than the external diameter of described driving shaft.
The installing hole coordinated with described driven shaft is provided with in the middle part of described handwheel.
One section of external surface that described driving shaft and described gear I fix is provided with external screw thread, and the centre bore medial surface of described gear I is provided with the internal thread matched with the external screw thread of described driving shaft external surface.
During utility model works, when gate rises, rotate counterclockwise rocking arm, gear I and ratchet are rotated counterclockwise, and gear I is rotated near frictional disk by internal thread and locks; During gate lock state, gear I and frictional disk remain locking state, in order to prevent gliding, blocking ratchet, prevent ratchet from turning clockwise by ratchet; When gate declines, rotate clockwise rocking arm, gear I is rotated by internal thread and departs from frictional disk, and ratchet 5 no longer works, and realizes hand function.
By test, the beneficial effects of the utility model are: by rotating rocking arm, gear I and ratchet are rotated counterclockwise, and gear I is rotated near frictional disk by internal thread and locks, and stability is high, achieves the rising and decline that complete gate in the event of a loss of power.
