Large-span steel truss girder cable hanging device and method
The invention relates to a large-span steel truss girder cable hanging device and method which are used for installing a stay cable of a whole-hole lifting appliance to a lower anchor beam of a steeltruss girder. The device comprises a support structure which is fixed on the surface of a lower anchor beam of a steel truss girder, a counter-force seat fixed at one end of the support structure, a deflecting pulley fixed at the other opposite end of the support structure, and a steel wire rope traction machine. One end of the steel wire rope traction machine is connected with the counter-force seat, the other end of the steel wire rope traction machine is connected with the deflecting pulley through a steel wire rope, the deflecting pulley is used for driving the steel wire rope to extend orretract, and a hook is arranged at the tail end of the steel wire rope and used for hanging the stay cable and pulling an anchor head of the stay cable to the lower anchor beam. According to the large-span steel truss girder cable hanging device and method, a stay cable does not need to be mounted or dismounted through an overwater floating crane, floating crane resources are saved, the construction safety risk is reduced, and the stay cable mounting period is shortened.
本发明涉及一种大跨度钢桁梁挂索装置及方法，用于将整孔吊装吊具的斜拉索安装至钢桁梁的下锚梁，其包括：支架结构，固定于所述钢桁梁的下锚梁表面；反力座，固定于所述支架结构的一端；转向滑轮，固定于所述支架结构的相对另一端；钢丝绳牵引机，其一端连接所述反力座，另一端通过钢丝绳与所述转向滑轮连接，所述转向滑轮用于带动所述钢丝绳伸长或缩短，所述钢丝绳的末端设有挂钩，用于挂住所述斜拉索并将所述斜拉索的锚头牵引至所述下锚梁。本发明的一种大跨度钢桁梁挂索装置及方法可以不需要使用水上浮吊安装或拆卸斜拉索，节约了浮吊资源，且降低了施工安全风险，缩短了安装斜拉索工期。
