FAN INTEGRAL INSTALLING ROTARY HOLD-LIFTING MECHANISM

摘要

A fan integral installing rotary hold-lifting mechanism for a marine fan installing platform is disclosed. The mechanism includes: a bearing beam (61) which is arranged between two upright posts (17) of a door-shaped frame (16) and can move upward and downward along the two upright posts (17); a central circular ring (68) provided in the middle of the bearing beam (61); a plurality of hanging rods (69) arranged on the lower end of the central circular ring (68); a hanging basket (70) hung on the lower end of the central ring (68) by the hanging rods (69); a plurality of holding devices (7) circumferentially distributed on the basket (70); a torsion device (51), a transverse micro-adjustment mechanism (52) and a longitudinal micro-adjustment mechanism (53) all of which are used for driving the basket (70) to rotate or move horizontally and arranged between the basket (70) and a connecting frame (50). The mechanism can conveniently align the tower cylinder center with the connecting flange bolt hole when the tower cylinder is held from the lower side of fan. When the install work is finished, the installing platform can depart the fan once the rotary hold-lifting mechanism is opened.
