The invention discloses a manned pole climbing operation platform and a pole holding mechanism thereof. The pole holding mechanism comprises a
cantilever and a
tail end pole holding mechanical arm. The
tail end pole holding mechanical arm comprises a front clamping jaw, a rear clamping jaw, a front fulcrum rotating shaft, a rear fulcrum rotating shaft, a front thrust nut composite rotating shaft,a rear thrust nut composite rotating shaft, a right-hand thread screw, a left-hand thread screw, a
kinetic energy striking type spiral pre-tightening device and a
pressure sensor. The front clamping jaw, the rear clamping jaw and the
cantilever are hinged through fulcrum rotating shafts. The
kinetic energy striking type spiral pre-tightening device is used for driving the positive thread screw andthe negative thread screw to rotate synchronously. The positive thread screw and the front clamping jaw are hinged through a front thrust nut composite rotating shaft, the negative thread screw and the rear clamping jaw are hinged through a rear thrust nut composite rotating shaft, and the front clamping jaw and the rear clamping jaw are oppositely opened or closed so as to clamp or separate froman electric pole. The pole holding mechanism can tightly hold an electric pole within a certain
diameter range, and has enough pole holding force so as to ensure the safety of manned pole climbing.
