Suspender tensioning device and suspender tensioning method
The invention provides a suspender tensioning device and a suspender tensioning method. The suspender tensioning device and the suspender tensioning method are used for solving the problems that an existing tensioning device is heavy and inconvenient to install and adjust. The suspender tensioning device comprises a fixed part, a movable part, an anchoring part, at least two force transmission pieces and at least two linear jacking devices. The fixed part is installed on the lifting rod on the upper side of the adjusting screw and cannot move downwards at least, and the fixed part is providedwith at least one first channel respectively on the two sides of the lifting rod. The first channels are through in the vertical direction and allow the force transmission piece to freely penetrate through; the movable part is mounted on the lifting rod above the fixed part and can linearly move up and down; the at least two force transmission pieces are divided into two sets and are arranged on the two sides of the lifting rod respectively, the upper end of each force transmission piece is anchored on the movable part, and the lower end of each force transmission piece vertically and downwards penetrates through the corresponding first channel and then is anchored on the bridge body or the lifting rod below the adjusting lead screw through the anchoring part; the at least two linear jacking devices are installed between the fixed part and the movable part and can push the movable part to be away from the fixed part.
本发明提供一种吊杆张拉装置和吊杆张拉方法，用于解决现有张拉装置笨重，不便于安装调整的问题。吊杆张拉装置包括：固定部、移动部、锚固部、至少两根传力件、至少两个直线顶升装置；固定部安装在调节螺杆上侧的吊杆上，且至少不能向下移动，吊杆两侧的固定部上分别设置有至少一第一通道，第一通道沿上下方向贯通且允许传力件自由穿过；移动部安装在固定部上方的吊杆上，并能上下直线移动；至少两根传力件分成两组并分别设置在吊杆的两侧，每一传力件的上端锚装在移动部上，每一传力件的下端竖直向下穿过对应的第一通道后通过锚固部锚装在调节螺杆下方的桥体或吊杆上；至少两个直线顶升装置安装在固定部和移动部之间且能推动移动部远离固定部。
