Bridge vertical prestressed tendon intelligent tensioning equipment

ZHANG XIUYUE

The invention discloses bridge vertical prestressed tendon intelligent tensioning equipment, which structurally comprises a fixed lock, an anchor ring, a jack and a hoisting piece, wherein the fixed lock is movably clamped to the inner side of the upper end of the anchor ring, the anchor ring is connected to the inner side of the upper portion of the jack in a riveted mode, and the hoisting piece is connected to the left front portion of the jack in a welded mode; the fixed lock is composed of a bottom ring, a built-in piece, a collecting device and a fixing hole, the built-in piece is fixedly connected to the inner side of the bottom ring in a built-in mode, and in the tensioning process, an attaching layer is matched with a rubber pad to be attached to the outer wall of the prestressed tendon, so that a certain protection effect on the prestressed tendon is achieved, friction during pulling is reduced, and rust is prevented from falling off;when the equipment moves, pulls and rubs, the friction-off rust falls off along the edge of the smooth sliding plate, enters from different through rings distributed on the gathering plate during falling, and then slides to a peripheral slide way along the top of the arc button, so that the falling rust can be conveniently and effectively collected and treated, and the rust is prevented from being clamped in a crack of a fixed lock.

本发明公开了一种桥梁竖向预应力筋智能张拉设备，其结构包括固定锁具、锚环、千斤顶、吊取件，固定锁具活动卡合于锚环上端内侧，锚环铆合连接于千斤顶上方内侧，吊取件焊接连接于千斤顶左前方；固定锁具由底环、嵌固片、收集装置、固定孔组成，嵌固片嵌固连接于底环内侧，张拉过程中贴合层配合橡胶垫贴合于预应力筋外壁，有利于对预应力筋起到一定的防护作用，减少拉扯时的摩擦避免铁锈掉落，而当设备移动拉扯摩擦时，摩擦掉的铁锈会沿着顺滑板的边缘掉落，掉落时会从聚集板分布的不同通环进入，随后沿圆弧钮的顶部滑落到周边的滑道处，便于对掉落的铁锈有效的收集处理，防止卡合于固定锁具的夹缝中。
