The invention discloses a hand-operated self-lifting device for wire dropping of a
power transmission line, which is applied to the field of high-altitude
power transmission line operation and comprises an anti-falling device body, a grip, a driving rocking
handle, an anti-falling chain, a buffer mechanism and the like. The anti-falling chain is wound on a specially-designed chain groove of the driving shaft body, and the shaft body is rotated by hand-cranking the driving rocking
handle, so that the anti-falling chain smoothly lifts an operator. The anti-falling chain can relieve
impact at the falling moment and protect safety of personnel and equipment, the hand-operated rocking
handle is provided with the one-way transmission design of the
ratchet wheel deflector rod and the gear ring, reverse rotation of the chain is prevented, the lifting chain groove structure, the limiting guide groove wheel and the blocking piece
system are accurately matched, smooth operation of the anti-falling chain is guaranteed, blocking is prevented, and it is guaranteed that the lifting process is stable and reliable. And the O-shaped hook lock equipped with the anti-scraping protection pad can protect the
power transmission line from being worn. The device is compact and light, is easy to carry and quick to deploy, and remarkably improves the safety of high-altitude operation and the reliability of the device.
