After the tensioning is completed, the section beams 41 are assembled to form the box beam 4, the hanging beam anchor 122 is connected with the box beam 4 through a second screw rod by using a second hole position 1222, then the hanging of the middle hanging beam crane 3 and all the guide pieces 19 are removed, and the final beam falling operation is completed by a beam falling device.
When the beam falling operation is performed, the hoisting mechanism 13 is driven by the winch 131 to lower the steel wire rope 132, and synchronously, the movable pulley block 15 and the beam body 121 are lowered, so that the beam falling operation is finally completed. Meanwhile, because the trolley frame 111 is directly positioned on the track beam on the main beam 2 of the bridge girder erection machine, under the action of the longitudinal moving device 18 and the transverse moving device 17, when the box beam 4 needs to be aligned in the falling process, the adjustment can be correspondingly carried out to a certain extent.
