The invention relates to a lifting type projector hanging bracket which comprises a ceiling. The two sides of the lower end face of the ceiling are symmetrically provided with two winding devices. A T-shaped fixing table is arranged below the ceiling. The lower end face of the T-shaped fixing table is symmetrically provided with two telescopic rods. The lower ends of the two telescopic rods are provided with a projector support in a welded mode. The two sides of the upper end face of the projector support are symmetrically connected with two hanging lugs in a welded mode. Telescopic ropes are wound around the hanging lugs. The other ends of the telescopic ropes are connected with the winding devices. The two sides of the projector support are connected with flexible skirt edges. Each winding device comprises two supporting tables arranged below the ceiling. A rotating shaft is arranged between the two supporting table through bearings. The rotating shafts are connected with the output ends of drive motors through couplings. The drive motors are arranged on motor racks. The motor racks are arranged below the ceiling. The middles of the rotating shafts are provided with fixed pulleys through keys. The fixed pulleys are wound around shrinkage ropes. The lifting type projector hanging bracket can achieve the lifting and telescopic functions and has the advantages of being simple in structure, good in shrinkage performance, wide in application range and the like.
