Bridge segment lifting device and method
The invention relates to a bridge segment lifting device and method. A beam top lifting device placed at the top of an erected beam segment and a beam bottom lifting device placed at the bottom of the erected beam segment are included. The beam bottom lifting device comprises a lower walking track. A front wheel pair and a back wheel pair are arranged on the lower walking track. A between-track-front-wheel-pair-and-back-wheel-pair rigid connecting piece is arranged between the front wheel pair and the back wheel pair. Lifting devices are arranged on the front wheel pair and the back wheel pair. A power group which can move along the track is arranged on the back wheel pair. The beam top lifting device comprises a segment lifting state converting and lifting counterpoint mechanism arranged at the top of the erected beam segment. A front horizontal beam and a back horizontal beam are arranged on the mechanism. Lifting devices are arranged on the front horizontal beam and the back horizontal beam. A between-front-horizontal-beam-and-back-horizontal-beam rigid connecting piece is arranged between the front horizontal beam and the back horizontal beam. A pulling pressing jack is arranged at the front end of the top of the mechanism. The bridge segment lifting device and method have the advantages that the field application range of bridge segment lifting and splicing working can be expanded.
