Mechanized erection mechanism and erection method for through bridge
The invention relates to a mechanical erection mechanism and method for a through bridge, and belongs to the technical field of bridge erection devices. The erecting mechanism comprises an erecting portal frame, a guide beam sleeve frame, an overturning frame, a moving frame and a pushing oil cylinder; a lower cross beam group for erecting the portal frame is hinged with one end of the movable frame; an upper cross beam group for erecting the portal frame is hinged with one end of the guide beam sleeve frame; one end of the turnover frame is hinged with the other end of the guide beam sleeve frame; the other end of the overturning frame is hinged to a cross beam II of the movable frame, and the connecting lines of the connecting points of the erecting portal frame, the guide beam sleeve frame, the overturning frame and the movable frame can form a parallelogram; the end, connected with the erecting portal, of the movable frame is the front end, and the end, connected with the overturning frame, of the movable frame is the rear end. The cylinder body end of the pushing oil cylinder is hinged to the middle position of a cross beam II at the rear end of the movable frame, and the telescopic end of the pushing oil cylinder is hinged to the overturning frame. The erection mechanism is high in mechanization degree, and when the erection mechanism is adopted for bridge erection, the erection time is short, and the efficiency is high.
本发明涉及一种下承式桥梁的机械化架设机构及架设方法，属于桥梁架设装置技术领域。所述架设机构包括架设门架、导梁套架、翻转架、移动架和顶推油缸；架设门架的下横梁组与移动架的一端铰接；架设门架的上横梁组与导梁套架的一端铰接；翻转架的一端与导梁套架的另一端铰接；翻转架的另一端与移动架的横梁II铰接，架设门架、导梁套架、翻转架以及移动架之间相连的连接点的连线能够形成平行四边形；令移动架与架设门架相连一端为前端，移动架与翻转架相连的一端为后端；顶推油缸的缸体端与移动架后端的横梁II的中间位置铰接，顶推油缸的伸缩端与翻转架铰接。所述架设机构机械化程度高，采用所述架设机构进行桥梁架设，架设时间短、效率高。
