Power transmission tower capable of utilizing thin-wall buckling torsion and preventing extension arm torsion
The invention discloses a power transmission tower capable of utilizing thin-wall buckling torsion and preventing extension arm torsion, and belongs to the technical field of power transmission towers. The power transmission tower comprises a main tower, a low-hanging-point single rotating arm, a thin-wall pipe and a high-hanging-point bracket, the low-hanging-point single rotating arm is arrangedbetween the main tower and the high-hanging-point bracket, and the thin-wall pipe is arranged between the low-hanging-point single rotating arm and the high-hanging-point bracket; and the main towercomprises main tower rotating shafts, a main tower clamping plate, a main tower sand groove and a shaft hole, the main tower sand groove with an opening in the upper end is formed in the top end of the main tower, the two main tower rotating shafts are welded to the lower bottom surface of the main tower sand groove, and the main tower clamping plate is welded to the end opening in the upper end of the main tower sand groove. The stability and safety of ordinary use are improved, the low-hanging-point single rotating arm rotates in case of an accident, the arm of force of horizontal force after rotation is reduced, the bending moment of the low-hanging-point single rotating arm is reduced, and the torque transmitted to the main tower is also reduced, so that the safety of the main tower isalso improved, and the corresponding manufacturing cost can also be reduced.
本发明公开了一种利用薄壁屈曲扭转的防伸臂扭力的输电塔，属于输电塔技术领域，包括主塔、低挂点单旋转臂、薄壁管和高挂点支架，所述主塔和高挂点支架之间安装有低挂点单旋转臂，所述低挂点单旋转臂和高挂点支架之间设有薄壁管；所述主塔包括主塔转轴、主塔卡板、主塔砂槽和轴孔，所述主塔的顶端开设有上端敞口的主塔砂槽，所述主塔砂槽的下底面上焊接有两根主塔转轴，且主塔砂槽的上端端口处焊接有主塔卡板。提高平时使用的稳定性和安全性，事故时低挂点单旋转臂发生旋转，旋转后水平力的力臂减小，低挂点单旋转臂的弯矩的减少，传递到主塔上的扭矩也发生了减少，因此主塔的安全性也提高了，相应的造价也可以减少。
