The present application belongs to the field of bridge girder erection machine overpass technology, and discloses an auxiliary device and a method for realizing small-radius curve overpass of a bridge girder erection machine by using the auxiliary device. The auxiliary device comprises a hanger wheel assembly, a connecting frame, a plurality of limiting mechanisms and an adjusting assembly. The hanger wheel assembly is arranged to roll on the main beam of the bridge girder erection machine. The hanger wheel assembly is connected to the connecting frame, and the connecting frame is arranged on the walking mechanism. The limiting mechanism is connected to the connecting frame, and the limiting mechanism is arranged to be spaced apart from the main beam of the bridge girder erection machine to limit the main beam of the bridge girder erection machine in the transverse direction. The adjusting assembly comprises an adjusting pad, which is clamped between the limiting mechanism and the connecting frame. The distance between the limiting mechanism and the main beam of the bridge girder erection machine can be changed by increasing or decreasing the adjusting pad. The limiting mechanism is arranged to be spaced apart from the main beam of the bridge girder erection machine, so that the main beam of the bridge girder erection machine can be limited to avoid transverse instability and reduce damage to the outer side of the main beam. The size of the spacing can be changed by increasing or decreasing the adjusting pad to realize real-time limiting and ensure safe overpass.
