Abstract

Provided are a manned pole-climbing work platform and a pole-gripping mechanism thereof. The pole-gripping mechanism includes an arm and a distal pole-gripping mechanical hand. The distal pole-gripping mechanical hand includes a front jaw, a rear jaw, a forward-threaded rod, a reverse-threaded rod and a preloader. The front jaw and the rear jaw are articulated with the arm through pivots. The preloader is configured to drive the forward-threaded rod and the reverse-threaded rod to rotate synchronously. The forward-threaded rod and the front jaw are articulated with each other through a front thrust-nut composite pivot. The reverse-threaded rod and the rear jaw are articulated with each other through a rear thrust-nut composite pivot. The front jaw and the rear jaw are openable or closeable relative to each other.
