The invention provides an adjustable arch rib installing and hoisting device which comprises an arch rib to be hoisted, a hoisting support, a pulley block for hoisting and hoisting and a steel wire rope. Arch rib hoisting lugs are arranged at the two ends of the arch rib, and the hoisting support comprises hoisting rods connected with the arch rib hoisting lugs, a cross beam arranged above the hoisting rods, a main longitudinal beam arranged longitudinally, a hoisting plate arranged at the center of the main longitudinal beam and a position adjusting inclined rod arranged between the main longitudinal beam and the hoisting plate. One end of the position adjusting inclined rod is rotatably connected with the hoisting plate, the other end of the position adjusting inclined rod is rotatably connected with the main longitudinal beam, one ends of the hoisting rods are rotatably connected with the arch rib hoisting lugs, the other ends of the hoisting rods are rotatably connected with the cross beam, the hoisting plate is rotatably connected to the upper end of the main longitudinal beam, the pulley block is arranged at the upper end of the hoisting plate, and the steel wire rope is connected with the pulley block. According to the adjustable arch rib installing and hoisting device, the structure is simple, operation is convenient, the transverse angle and the vertical elevation of arch ribs are finely adjusted by utilizing the hoisting rods and the position adjusting inclined rod, the butt joint work efficiency of the arch ribs is increased, the arch ribs realize seamless butt joint of hoisting and mounting, and the construction safety risk is reduced.
