Main tower torsion preventing power transmission tower utilizing thin-wall buckling torsion
The invention discloses a main tower torsion preventing power transmission tower utilizing thin-wall buckling torsion. The main tower torsion preventing power transmission tower comprises a power transmission tower body, the upper end of the power transmission tower body is fixedly connected with a main tower rotating shaft, the main tower rotating shaft is sleeved with a low-hanging-point rotating arm and a thin-wall pipe, and the upper end of the main tower rotating shaft is fixedly connected with a top supporting block; and a fixing ring groove is formed in the lower surface of the top supporting block, internal threads are formed in the inner wall of the fixing ring groove, and a limiting supporting plate is arranged at the joint of the main tower rotating shaft and the power transmission tower body. According to the main tower torsion preventing power transmission tower utilizing the thin-wall buckling torsion, the thin-wall pipe has large bearing capacity, deformation of the low-hanging-point rotating arm is limited, under the accident working condition, the thin-wall pipe is bent, the bearing capacity is reduced, and therefore the low-hanging-point rotating arm is allowed torotate; and although the horizontal force of the power transmission tower body is basically unchanged after rotation, the arm of force of the horizontal force is greatly reduced and even is zero, andthe torsion force of the main tower caused by the accident load can be reduced to a great extent through rotation.
本发明公开了一种利用薄壁屈曲扭转的防主塔扭力输电塔，包括输电塔本体，所述输电塔本体的上端固定连接有主塔转轴，主塔转轴上套接有低挂点旋转臂和薄壁管，主塔转轴的上端固定连接有顶部支撑块，顶部支撑块的下表面开设有固定环槽，固定环槽的内壁上开设有内螺纹，主塔转轴与输电塔本体的连接处设置有限位支撑板。本利用薄壁屈曲扭转的防主塔扭力输电塔，薄壁管有较大的承载力，限制了低挂点旋转臂的变形，在事故工况下，薄壁管发生屈曲，承载力下降，从而允许低挂点旋转臂发生旋转，旋转后，输电塔本体虽然水平力基本不变，但是水平力的力臂会大大减小，甚至将为零，旋转可以非常大的程度上减小主塔受到事故荷载带来的扭转力。
