The present invention relates to a rigid trolley bar bracket structure and comprises: a semicircular screw guide groove (21) formed in a hanger bar (20); a lifting screw (30) inserted into the screw guide groove (21) and rotated; a semicircular screw groove (41) screwed to half of the lifting screw (30) and formed in a lifting plate (40); an upper annular groove (31) formed on the outer peripheral surface of the upper end of the lifting screw (30); an upper saddle (50) in close contact with the upper annular groove (31) and installed on the hanger bar (20); a lower annular groove (32) formed on the outer peripheral surface of the lower end of the lifting screw (30); a lower saddle (51) in close contact with the lower annular groove (32) and installed on the hanger bar (20); ring guide grooves (22) formed in double rows on the hanger bar (20); a pair of U-bolts (60) connected at both ends to the lifting plate (40) and installed at a distance from each other in the vertical direction while surrounding the hanger bar (20); and a donut ring (61) installed on the U-bolt (60) and rolling along the ring guide groove (22). Accordingly, the lifting plate (40) can be prevented from falling due to its own weight.
