Foldable main beam system
The invention discloses a foldable main beam system which comprises two longitudinal beams consistent in structure, each longitudinal beam comprises a main beam composed of at least two main beam sections, the main beam sections are connected through a hinge joint, and guide beams are arranged at the two ends of each main beam; connecting beams are arranged on the longitudinal beams, and the connecting beams on the two longitudinal beams are connected with each other, so that the main beam system is of a frame structure; the invention has the following beneficial effects: the main beam sections can be horizontally and rotatably connected through the hinge joints, so that the construction under the working condition of a small-radius curve can be better coped with; the two longitudinal beams are connected into a whole through the connecting beams to form a frame structure, so that the gravity center of the main beam system is located between the two longitudinal beams, and the hidden danger of transverse overturning in the small-radius curve state construction process is avoided.
本发明公开了一种可折式主梁系统，包括两根结构一致的纵梁，纵梁包括至少两根主梁段组成的主梁，主梁段之间通过铰接头连接，主梁的两端设置有导梁；所述纵梁上设置有联系梁，两处纵梁上的联系梁互相连接使得主梁系统呈框架结构；本发明所具有的有益效果为：主梁段之间通过铰接头可平转连接，可更好地应对小半径曲线工况的施工；两处纵梁通过联系梁联为一体形成框架结构，使主梁系统的重心位于两处纵梁之间，避免了小半径曲线状态施工过程的横向倾覆隐患。
