Abstract
The invention discloses a hand cranking mechanism of a winch type opening and closing machine and belongs to the technical field of winch type opening and closing machine gate driving equipment. According to the technical scheme, the hand cranking mechanism of the winch type opening and closing machine comprises a machine shell, a driving shaft and a driven shaft. The driving shaft and the driven shaft are arranged in the machine shell. A friction plate fixed to the driving shaft, a ratchet wheel and a gear I are sequentially arranged in the axial direction of the driving shaft. The end, stretching out of the outer side of the machine shell, of the driving shaft is provided with a crank. The hand cranking mechanism has the beneficial effects that the gear I and the ratchet wheel rotate anticlockwise by rotating a rocker arm; the gear I gets close to the friction plate through rotation of internal threads and is locked; and stability is high. When a gate is in a locked state, the gear I and the friction plate are still locked, the ratchet wheel is clamped through a pallet, and the ratchet wheel is prevented from rotating clockwise. When the gate descends, the rocker arm rotate clockwise, the gear I breaks away from the friction plate through rotation of the internal threads, the ratchet wheel breaks away from the pallet, and the gate can ascend and descend when power failure happens.
Description

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.
When the present invention 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 no longer works, and realizes hand function.
By test, the invention has the beneficial effects as follows: by rotating rocking arm, gear I and ratchet are rotated counterclockwise, gear I is rotated near frictional disk by internal thread and locks, and stability is high; When gate is in the lock state, gear I and frictional disk remain locking state, ratchet blocks ratchet, prevent ratchet from turning clockwise, when gate declines, rotate clockwise rocking arm, gear I is rotated by internal thread and departs from frictional disk, ratchet and ratchet depart from, and achieve the rising and decline that complete gate in the event of a loss of power.
