Splicing bridge girder erection machine
The invention provides a splicing bridge girder erection machine, a front main support leg is mounted on a main beam at a front end saddle beam, the front main support leg comprises an upper oblique beam, a middle straight beam, a lower curved beam, a mounting seat and an oil cylinder seat which are sequentially connected from top to bottom, the height of the middle straight beam is consistent with that of an erected box beam, and the lower curved beam is L-shaped and faces the center line of the front main support leg; the main hoisting crown block is installed on the portion, close to the inner side, of the upper portion of the main frame, the front beam falling device and the rear beam falling device are both installed on the portion, close to the outer side, of the upper portion of the main beam, crown block jacking oil cylinders are installed at the four corners of the top of the main hoisting crown block, and the crown block jacking oil cylinders jack the front beam falling device or the rear beam falling device to move longitudinally. The hanging assembly comprises a hanging tool and a hanger, and a longitudinal slope adjusting oil cylinder and a transverse slope adjusting oil cylinder are installed on the hanging tool. The splicing bridge girder erection machine is suitable for construction of simply-supported box girders of single-line and double-line railways, can adapt to curve construction and transverse moving erection construction of multiple beams, and can meet tail beam feeding, underground beam feeding and beam feeding in front of a bridge.
本发明提供了一种节拼架桥机，前主支腿安装于前端马鞍梁处的主梁上，前主支腿包括由上至下依次连接的上斜梁、中直梁、下曲梁、安装座和油缸座，中直梁的高度与已架箱梁的高度一致，下曲梁呈“L”字型并朝向前主支腿的中心线；主起重天车安装于主框架的上部靠内侧部位上，前落梁装置和后落梁装置均安装于主梁的上部靠外侧，主起重天车的顶部四角处安装有天车顶升油缸，天车顶升油缸顶升前落梁装置或后落梁装置纵向移动；吊挂总成包括吊具和吊挂，吊具上安装有纵向调坡油缸和横向调坡油缸。该节拼架桥机适用于单、双线铁路简支箱梁的施工并能适应曲线施工和多幅梁的横移架设施工，能满足尾部喂梁、地下喂梁和桥前喂梁。
