The invention discloses a lifting device for a rudder system polymer bushing. The lifting device of the rudder system polymer bushing comprises a center stand column, a lifting screw hole is formed in the top of the center stand column, three lifting stand columns are arranged on the periphery of the center stand column and evenly distributed around the axis of the center stand column in a circumferential mode, and first arc-shaped plates for bearing the bushing are arranged at the bottoms of the lifting stand columns. First connecting rods are arranged between the lifting stand columns and the center stand column, one end of each first connecting rod is pivoted to the lifting stand column, the other end of the first connecting rod is pivoted to the center stand column, the upper middle portion of the center stand column is in threaded connection with a positioning ring, and an adjusting ring is arranged at the top of the positioning ring and connected to the outer side of the center stand column in a sleeving mode. Pull rods are arranged between the adjusting rings and the first connecting rods, one end of each pull rod is pivoted with the adjusting ring, and the other end is pivoted with the first connecting rod. The problems that in the prior art, operation is tedious, stability is poor, and the risk of interference with a bush installation step exists are solved.
