Longitudinal movement system and longitudinal movement method of steel truss girder segments
The invention discloses a longitudinal movement system and longitudinal movement method of steel truss girder segments. The longitudinal movement system comprises a track fixing device (1), wherein a hoisting and conveying device (2) is arranged under the track fixing device (1); the track fixing device (1) comprises an upper balance beam (3); the upper balance beam (3) is connected with a lower balance beam (5) through steel bars (4); track beams (6) are arranged under the lower balance beam (5); the track beams (6) are connected with girder conveying trolleys (8); positioning trolleys (9) are also connected to the track beams (6) behind the girder conveying trolleys (8); hoisting and conveying ropes (10) are arranged on the hoisting and conveying device (2). The longitudinal movement system disclosed by the invention has the characteristics that the construction workload is reduced; the construction cost is reduced; the construction time is shortened; the construction efficiency is improved; the resistance to the girder conveying trolleys is reduced.
