Bridge girder erection machine suitable for erection of continuous steel box girder ramp and erection construction method
The invention discloses a bridge girder erection machine suitable for erection of a continuous steel box girder ramp and an erection construction method. The bridge girder erection machine comprises a supporting truss girder, a front lifting crown block, a rear lifting crown block, a main supporting leg, a middle main supporting leg, a rear supporting leg and a front guide supporting leg. Connecting beams are hinged to the two ends of the supporting truss beam; the main bearing beams on the outer sides of the two front main supporting legs are rotationally connected with the carrier roller wheel box through rotating shafts. The lower connecting bases of the two rear supporting legs are rotationally connected with the two sides of the lower supporting beam through rotating shafts correspondingly. The lower portions of the two ends of the transverse moving track beams of the front lifting crown block and the rear lifting crown block are rotationally connected with the longitudinal moving wheel sets through rotating shafts. And position locking devices are arranged at the rotating joints. According to the method, the ramp continuous steel box girder with a small curve, a large span and a large lifting height can be safely and efficiently erected and constructed.
本发明公开了一种适用于连续钢箱梁匝道架设的架桥机和架设施工方法，包括支撑桁架梁、前起升天车、后起升天车、主支撑支腿、中主支撑支腿、后支撑支腿和前引导支腿；支撑桁架梁的两端均铰接有连接梁；两条前主支撑支腿外侧的主承重梁与托辊轮箱通过转动轴转动连接；两条后支撑支腿的下连接座分别与下支撑梁的两侧通过转动轴转动连接；前起升天车和后起升天车的横移轨道梁的两端下部均通过转动轴与纵移轮组转动连接；且上述转动连接处均设置有位置锁定装置。本发明能够安全高效地对于小曲线、大跨度和大起升高度的匝道连续钢箱梁进行架设施工。
