The invention relates to a vertical tensioning device, in particular to a vertical tensioning device convenient for fixing a steel strand. Comprising a center hole jack, a fixed mounting frame, a limiting circular plate, a working anchor plate, a hollow limiting frame, working clamping pieces and the like, a piston of the center hole jack is connected with the fixed mounting frame, the fixed mounting frame is connected with the limiting circular plate, the working anchor plate is placed in the fixed mounting frame, and the working clamping pieces are placed in anchor holes of the working anchor plate. The working anchor plate is connected with a hollow limiting frame used for limiting the working clamping pieces. The center hole jack is arranged on the steel strand body in a sleeving mode, the steel strand body can automatically penetrate through the center hole jack, the fixed top plate, the working anchor plate and the working clamping piece, manual sequential installation is not needed, then a piston of the center hole jack is controlled to drive the fixed installation frame to move upwards, the working clamping piece can clamp the steel strand body, and the steel strand body can be automatically fixed. The steel strand tensioning device is easy to operate, and the working efficiency can be improved.
本发明涉及一种竖向张拉器，尤其涉及一种便于钢绞线固定的竖向张拉器。包括有穿心式千斤顶、固定安装框、限位圆板、工作锚板、空心限位框和工作夹片等，穿心式千斤顶的活塞上连接有固定安装框，固定安装框上连接有限位圆板，固定安装框内放置有工作锚板，工作锚板的锚孔内均放置有工作夹片，工作锚板上连接有用于对工作夹片进行限位的空心限位框。本发明通过将穿心式千斤顶套在钢绞线本体上，可使钢绞线本体自动穿过穿心式千斤顶、固定顶板、工作锚板和工作夹片，无需人工依次进行安装，然后控制穿心式千斤顶的活塞驱动固定安装框往上运动，可使工作夹片将钢绞线本体夹紧，并对钢绞线本体进行竖向张拉，操作简单，能提高工作效率。
