Steel strand pulling auxiliary device and method
The invention discloses a steel strand pulling auxiliary device and method. The steel strand pulling auxiliary device comprises a power mechanism and a traction mechanism. The power mechanism is arranged at the end part of the beam bridge which is not subjected to steel strand pulling operation; the traction mechanism comprises a traction rod, a first limiting component and a second limiting component; the first end of the traction rod is connected with the output end of the power mechanism, and the second end of the traction rod obliquely extends in the direction of the area between the two adjacent span bridges. Wherein the power mechanism is used for driving the traction rod to reciprocate back and forth in the same vertical plane; the first limiting component and the second limiting component are arranged at the second end of the traction rod in parallel in a spaced mode, and the to-be-operated prestressed steel strand is located between the first limiting component and the second limiting component. The traction rod reciprocates back and forth, so that tension is continuously provided for the to-be-operated prestressed steel strand, the steel strand advances along a prestressed duct, manual operation is replaced to carry out auxiliary strand pulling operation on the prestressed steel strand in a narrow space, the number of operators is reduced, and the operation time is shortened.
本发明公开了一种钢绞线穿束辅助装置及方法，包括动力机构及牵引机构；动力机构设置在未进行钢绞线穿束作业的梁桥端部；牵引机构包括牵引杆、第一限位构件及第二限位构件；牵引杆的第一端与动力机构的输出端相连，牵引杆的第二端朝相邻两跨梁桥之间区域方向倾斜延伸；其中，动力机构用于驱动牵引杆在同一竖直平面内前后往复移动；第一限位构件与第二限位构件平行间隔设置在牵引杆的第二端，待作业的预应力钢绞线位于第一限位构件与第二限位构件之间；本发明通过牵引杆的前后往复移动，实现持续为待作业的预应力钢绞线提供拉力，以使钢绞线沿预应力孔道行进，实现代替人工进行狭小空间内预应力钢绞线穿束辅助作业，减少了作业人员数量和作业时间。
