Height-adjustable bracket device and steel box girder mounting method
The invention discloses a height-adjustable bracket device and a steel box girder mounting method.The height-adjustable bracket device comprises a pair of symmetrically-arranged bracket mechanisms, each bracket mechanism comprises a pair of sub-bracket mechanisms, the pair of sub-bracket mechanisms are used for being arranged on parallel conveying rails correspondingly, and each sub-bracket mechanism comprises a fixed supporting section and a fixed supporting section; the upper end of the movable supporting section is fixedly connected with the lower bearing plate, the lower end of the movable supporting section is hinged to the first tensioning box, and the upper end of the movable supporting section is hinged to the lower bearing plate; the supporting platform comprises a lower bearing plate, an upper bearing plate and a universal spherical hinge mounted between the lower bearing plate and the upper bearing plate; and the first tensioning box and the second tensioning box are connected through a prestressed steel strand. A cross beam of an existing portal frame is omitted, the structure of the portal frame is simplified, the self weight of the portal frame is reduced, the transferring and lifting stability of the steel box girder is improved, and the turnover efficiency and the use efficiency of the portal frame are also improved.
本申请公开一种高度可调托架装置以及钢箱梁安装方法，装置包括一对对称布置的托架机构，每一托架机构都包括一对子托架机构，一对子托架机构用于分别设置在平行的运输轨道上，每一子托架机构都包括：固定支撑段，上端与下承压板固定连接，下端与第一张拉箱铰接，活动支撑段，上端与下承压板铰接，下端与第二张拉箱铰接；支承平台，包括下承压板、上承压板，以及安装在其之间的万向球铰；第一张拉箱和第二张拉箱，第一张拉箱和第二张拉箱之间通过预应力钢绞线连接。本申请取消了以往龙门架的横梁，简化了龙门架结构，减小了龙门架自重，提高钢箱梁的移送以及升降的稳定性，也增强了龙门架的周转效率和使用效率。
