Hoisting device and hoisting method for steel truss girder sections of steel truss girder cable-stayed bridge
The invention discloses a hoisting device and method for steel truss girder segments of a steel truss girder cable-stayed bridge. The hoisting device comprises a bridge deck crane, a guide rail, a girder transporting trolley, a fixed frame and a movable frame, and a hoisting mechanism is arranged on a cantilever frame of the bridge deck crane; the guide rails are arranged at the bottoms of the steel truss girder sections and are spliced at the bottom of the steel truss girder main body 2 to form a sliding track; the beam transporting trolley is connected to the sliding rail in a sliding mode, the movable frame is in an equilateral triangle shape, the three corners of the movable frame serve as a first connecting point, a second connecting point and a third connecting point respectively, the first connecting point is hinged to the lower end of the fixed frame, the second connecting point is hinged to the upper surface of the steel truss section, and the third connecting point is connected with a traction rope of the hoisting mechanism; the initial positions of the first connecting point and the second connecting point are both located on the vertical extension line of the fixing frame, the initial position of the third connecting point is located under the hoisting mechanism, and the hoisting device has the effect of improving the convenience, smoothness and stability of segmental beam hoisting construction.
本申请公开了一种钢桁梁斜拉桥钢桁梁节段吊运装置及其吊运方法，其包括桥面吊机、导轨、运梁小车、固定架以及活动架，桥面吊机的悬挑架设置有起吊机构；导轨设置在钢桁梁节段底部，若干导轨在钢桁梁主体2底部拼接形成滑移轨道；运梁小车滑动连接于滑移轨道，活动架呈等边三角形，活动架的三个角部分别作为第一连接点、第二连接点以及第三连接点，第一连接点铰接于固定架的下端，第二连接点铰接于钢桁梁节段的上表面，第三连接点与起吊机构的牵引绳连接；第一连接点和第二连接点的初始位置均位于固定架的竖向延长线上，第三连接点的初始位置位于起吊机构的正下方，本申请具有提高节段梁吊运施工的便捷性、流畅性以及稳定性的效果。
