一种环形混凝土电杆大弯矩张拉套件
摘要：
本发明公开了一种环形混凝土电杆大弯矩张拉套件，包括电杆钢模、张拉盘、定位板、支撑套管、锁紧螺母、张拉机，所述张拉盘设置在电杆钢模端部，包括预应力筋锚固盘、张拉承力丝杆，所述张拉承力丝杆的一端通过螺纹与预应力筋锚固盘固定连接，所述张拉承力丝杆的另一端与张拉机连接；所述定位板套设于张拉承力丝杆上，并紧靠电杆钢模的端部；所述支撑套管设置在定位板与张拉机之间；所述锁紧螺母套设于张拉承力丝杆上，位于定位板和牵引头之间。本发明结构简单，操作方便，承载能力强，结实耐用，试样品在上百次循环使用中，没有出现任何变形、磨损情况。
摘要（英）：

The invention discloses an annular concrete electric pole high-bending-moment tensioning assembly which comprises an electric pole steel die, a tensioning plate, a positioning plate, a supporting sleeve, a locking nut and a tensioning machine. The tensioning plate is arranged at one end of the electric pole steel die, and comprises a prestress rib anchoring plate and a tensioning force-bearing lead screw. One end of the tensioning force-bearing lead screw is fixedly connected with the prestress rib anchoring plate through threads. The other end of the tensioning force-bearing lead screw is connected with the tensioning machine. The positioning plate is arranged on the tensioning force-bearing lead screw in a sleeving mode and abuts against one end of the electric pole steel die. The supporting sleeve is arranged between the positioning plate and the tensioning machine. The locking nut is arranged on the tensioning force-bearing lead screw in a sleeving mode and located between the positioning plate and a traction head. The annular concrete electric pole high-bending-moment tensioning assembly is simple in structure, convenient to operate, high in bearing capacity, firm and durablein use, and test samples are free of deformation and abrasion after being recycled for hundreds of times.
