Portable installation prestress tensioning jack device
The invention relates to a portable installation prestress tensioning jack device comprising a first trapezoid vertical supporting leg (101), a second trapezoid vertical supporting leg (102), an inclined supporting arm (103), a transverse supporting arm (100), a transverse connecting rod (105), an electric hoisting system (109), a pulley system (108), a rolling shaft (107), a transverse connecting steel sleeve (106), a terminal stopping steel plate (110), an anchoring balance stabilizing hook (111) and a locking brake wheel (112). The device is optimized in structure, simple and clear, convenient to assemble, disassemble and move, good in stability performance and high in flexibility; and the hoisting position of the prestress tensioning jack is determined more quickly and conveniently, and the device is suitable for various poor construction environments, so that the problem of low prestress tensioning construction efficiency in the cast-in-place box girder of the bracket is better solved.
一种便携式安装预应力张拉千斤顶装置，包括第一道梯形竖向支撑腿（101）、第二道梯形竖向支撑腿（102）、斜支撑臂（103）、横向支撑臂（100）、横向连接杆（105）、电动吊装系统（109）、滑轮系统（108）、滚轴（107）、横向连接钢材套筒（106）、终端止挡钢板（110）、锚固平衡稳定钩（111）和锁刹轮（112）。本发明装置结构优化、简单明了，便于组装与拆卸，便于移动，稳定性能好，灵活性强；对预应力张拉千斤顶吊装位置的确定更快捷方便，适用于各种不良的施工环境，从而更好地解决支架现浇箱梁中预应力张拉施工效率低的问题。
