Temporary lifting point mounting system and method
The invention discloses a temporary lifting point installation system and method.The temporary lifting point installation system comprises a box girder bottom plate, a driving mechanism is suspended above the box girder bottom plate, the output end of the driving mechanism is connected with a lifting point through a lifting assembly, the lifting assembly movably penetrates through the box girder bottom plate, and the lifting point abuts against the bottom of the box girder bottom plate by driving the lifting assembly; the box girder bottom plate is further provided with a locking mechanism used for fixing the lifting assembly. The condition of large-tonnage hoisting can be achieved by installing the temporary hoisting point and matching with simple equipment such as a pulley block, the applicability is wider, limitation of clearance at the bottom of a box girder is avoided, the method is feasible and economical when a support steel pipe pile foundation of a low-clearance box girder or a common box girder is pulled out, and compared with the design that a crane is matched with a vibratory hammer, the construction cost is reduced. According to the invention, the leasing and foundation treatment cost of large hoisting machinery is saved, the construction cost is greatly reduced, and the loss of materials is avoided.
本发明公开了一种临时吊点安装系统及方法，包括箱梁底板，箱梁底板的上方悬置有一驱动机构，驱动机构的输出端通过提升组件连接有吊点，提升组件活动贯穿所述箱梁底板，通过驱动提升组件将吊点顶接在所述箱梁底板的底部，箱梁底板上还设置有用于固定提升组件的锁紧机构。通过该临时吊点的安装，配合滑轮组等简易设备即可实现大吨位起重的条件，适用性更广，不受箱梁底部净空限制，无论是低净空箱梁还是一般箱梁，在拔除其支架钢管桩基础时都是可行且经济的，相比起重机配合振动锤的设计，本发明节省了大型起重机械的租赁和地基处理费用，极大地降低了施工成本，避免了材料的损耗。
