  • Publication number: 20130074337
    Abstract: A multifunctional platform includes a platform frame including a base having an annular center hole and two parallel arms, a hoist mechanism including traction devices and moves the platform up and down, tower clamping mechanisms around the circumference of the annular center hole and preventing the platform frame from rotating, a moving dolly sliding on the two arms, two blade adjusting pedestals respectively provided on the protruding ends of the two arms, two set of blade drawing mechanisms, one end of each set of blade drawing mechanism is respectively connected with one blade adjusting pedestal. The blade disassembling method includes lifting the multifunctional platform to an appropriate height of the tower by the hoist mechanism, tying sling ropes at three positions of a blade, disassembling the blade and lowering it to a transport ship by a crane ship, and a fan maintenance crane, and the blade drawing mechanisms.
