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.

The circumferentially disposed back-up ring of driving shaft between the gear I and casing, arranges locking screw in the side of the back-up ring
Nail.
Which is fixed with the driving shaft by the frictional disk by straight pin.
The crank is the rocking arm being connected with the fixed cover by hollow cylindrical fixed cover, one end, and is arranged on
The handle of the rocking arm other end.
The fixed cover is engaged with the driving shaft, external diameter of its internal diameter slightly larger than the driving shaft.
The installing hole coordinated with the driven shaft is provided with the middle part of the handwheel.
The driving shaft one section outer surface fixed with the gear I phases is provided with external screw thread, the centre bore of the gear I
Medial surface is provided with the internal thread being engaged with the external screw thread of the driving shaft outer surface.
During present invention work, when gate rises, rocking arm, gear I and ratchet rotate counterclockwise, gear I are rotated counterclockwise
Rotate near frictional disk and lock by internal thread；During gate lock state, gear I and frictional disk remain locking state, in order to
Prevent from gliding, ratchet is blocked by ratchet, prevents ratchet from turning clockwise;When gate declines, rocking arm is rotated clockwise, gear I leads to
Cross internal thread and rotate and depart from frictional disk, 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 rotate counterclockwise, gear I
Rotate near frictional disk and lock by internal thread, stability is high；When gate is in the lock state, gear I and frictional disk are remained
Locking state, ratchet block ratchet, prevent ratchet from turning clockwise, and when gate declines, rotate clockwise rocking arm, and gear I passes through
Internal thread is rotated and departs from frictional disk, and ratchet is departed from ratchet, realizes the raising and lowering for completing gate in the event of a loss of power.
