The invention discloses a large-slab girder stacking beam installation device, which solves the technical problem that the existing upper and lower stacking beams are not tightly connected, which easily leads to joint cracking of the upper and lower stacking beams. The upper stacking beam (1) is arranged on the lower stacking beam (2), two left connecting frames are fixedly arranged at the left end of the upper stacking beam (1), and two right connecting frames are fixedly arranged at the right end of the upper stacking beam (1) , the other end of the left front frame beam (5) is hinged with the other end of the right front frame beam (6) through the top connecting pin (9), and the upper end of the front boom (10) is connected to the front end of the top connecting pin (9) , the upper end of the rear boom (17) is connected to the rear end of the top connecting pin (9), and a horizontal support beam (11) is connected between the front boom (10) and the rear boom (17). A jack (18) is arranged on the beam (11), and the upper end of the jack (18) is connected to the lower bottom surface of the lower stacking beam (2). The invention ensures the overall quality of boiler installation.
