Prestressed steel strand tensioning device for road and bridge construction

YANG YANG

The invention discloses a prestressed steel strand tensioning device for road and bridge construction. A telescopic column is installed at the rear end of a tensioning machine body, positioning sliding rods are installed on the left side and the right side of the telescopic column, the telescopic column is positioned in the left side and the right side of the tensioning machine body in an auxiliary mode through the positioning sliding rods, and the telescopic column is prevented from rotating in the telescopic process; a liquid inlet is formed in the front end of the top of the tensioning machine body, a liquid return opening is formed in the rear end of the top of the tensioning machine body, the liquid inlet controls the telescopic column to stretch, the liquid return opening controls the telescopic column to reset, and a steel strand fixing mechanism is installed in the center of the interior of the telescopic column; the steel strand fixing mechanisms can fix the steel strands to be tensioned respectively. The steel strand is fixed in the tensioning machine body through the built-in steel strand fixing mechanism, a large number of steel strands are saved, and damage caused by the fact that the steel strands fly out after the steel strands are broken in the tensioning process can be avoided.

本发明公开了一种用于路桥建设预应力钢绞线张拉装置，张拉机主体后端安装有伸缩柱，伸缩柱左右两侧安装有定位滑杆，且通过定位滑杆辅助定位在张拉机主体左右两侧内，防止伸缩柱伸缩中转动，张拉机主体顶部安装有固定块，且张拉机主体通过固定孔吊装在对应位置进行张拉作业，张拉机主体顶部前端安装有进液口，且张拉机主体顶部后端安装有回液口，进液口控制伸缩柱伸长进行张拉，回液口控制伸缩柱复位，伸缩柱内部中心安装有钢绞线固定机构,钢绞线固定机构可分别固定待张拉钢绞线。本发明通过内置钢绞线固定机构将钢绞线固定在张拉机主体内，不仅节省大量的钢绞线，还能在钢绞线张拉中发生断裂后，避免钢绞线飞出造成伤害。
