Power transmission tower utilizing ascent of hydraulic damping torsion extending arm
The invention discloses a power transmission tower utilizing ascent of a hydraulic damping torsion extending arm. The power transmission tower comprises a power transmission tower body, wherein the upper end of the power transmission tower body is symmetrically connected with main tower double-rotating shafts, the main tower double-rotating shafts are respectively sleeved with low-hanging-point single-rotating arms and hydraulic damper torsion supporting seats from bottom to top, the upper ends of the main tower double-rotating shafts are fixedly connected with top supporting blocks, the uppersurfaces of the top supporting blocks are fixedly connected with high-hanging-point supports, and the upper surfaces of the low-hanging-point single-rotating arms are fixedly connected with single-rotating-arm upper lug plates. According to the power transmission tower utilizing ascent of the hydraulic damping torsion extending arm, rotation of the low-hanging-point single-rotating arms is used for unloading horizontal force under the accident condition and torsional force caused by the low-hanging-point single-rotating arms, meanwhile, the problem that wires are too low due to rotation of the low-hanging-point single-rotating arms is solved, and the hydraulic damper torsion supporting seats are used to reduce wire breaking impact and structural vibration so as to limit the rotating speedof the low-hanging-point single-rotating arms and the power effect of the whole structure respectively.
本发明公开了一种利用液压阻尼扭转伸臂上升的输电塔，包括输电塔本体，所述输电塔本体的上端对称连接有主塔双转轴，主塔双转轴从下至上分别套接有低挂点单旋转臂和液压阻尼器扭转支座，主塔双转轴的上端固定连接有顶部支撑块，顶部支撑块的上表面固定连接有高挂点支架，所述低挂点单旋转臂的上表面固定连接有单旋转臂上耳板。本利用液压阻尼扭转伸臂上升的输电塔，利用低挂点单旋转臂的旋转来卸载事故工况下水平力与低挂点单旋转臂引起的扭转力，同时也解决了由低挂点单旋转臂转动引起的导线过低的问题，并且利用液压阻尼器扭转支座来减小断线冲击和结构振动，来分别限制低挂点单旋转臂的转动速度和结构整体的动力效应。
