Long-span prestressed concrete cast-in-place continuous box girder steel strand pulling device and steel strand pulling method.
The invention relates to bridge construction, in particular to a long-span prestressed concrete cast-in-place continuous box girder steel strand pulling device and a steel strand pulling method. The device comprises a steel strand pulling machine, a scaffold pipe, a sliding rod piece, a heavy drill chuck, a power transmission rod, a helical gear speed reducer, a three-phase asynchronous motor and a moving trolley, one end of the scaffold pipe is connected with a box girder pulling hole channel, the other end of the scaffold pipe is connected with a wire outlet of the steel strand pulling machine, the sliding rod piece is arranged at the bending position of a steel strand, and the heavy drill chuck is connected with one end of the power transmission rod. The other end of the power transmission rod is connected with the helical gear speed reducer, and the helical gear speed reducer is connected with the three-phase asynchronous motor and installed on the moving trolley; by reasonably utilizing the strand pulling machine, the three-phase asynchronous motor combination and the construction method, the phenomenon that long-distance and large-span steel strands cannot be normally pulled is effectively solved, and the steel strand pulling operation is efficiently completed.
本发明涉及桥梁施工，具体是一种大跨度预应力混凝土现浇连续箱梁钢绞线穿束装置及钢绞线穿束方法；包括，钢绞线穿束机、脚手管、滑动杆件、重型钻夹头、动力传输杆、斜齿轮减速机、三相异步电机、移动小车，脚手管一端连接箱梁穿束孔道，另一端连接钢绞线穿束机出线口，滑动杆件设置在钢绞线折弯处，重型钻夹头连接动力传输杆一端，连接动力传输杆另一端连接斜齿轮减速机，齿轮减速机连接三相异步电机，齿轮减速机安装在移动小车上；通过合理利用穿束机、三相异步电机组合及施工方法，有效解决了长距离、大跨度钢绞线无法正常穿束等现象，高效率完成钢绞线穿束作业。
