Power transmission tower with lead-core rubber torsion and rising
The invention discloses a power transmission tower with lead-core rubber torsion and rising, belonging to the technical field of power transmission towers. The power transmission tower with lead-corerubber torsion and rising includes a main tower, a low-hanging point single revolving arm, a laminated lead-core rubber steel plate torsion support and a high-hanging point bracket; a main tower double rotating shaft is fixedly connected between the main tower and the high-hanging point bracket; the main tower double rotating shaft is rotatably connected with the laminated lead-core rubber steel plate torsion support and a hinge connection device successively from top to bottom; and the hinge connection device is fixedly connected with the low-hanging point single revolving arm through bolts.Under a normal use state, the structure is stable and durable; and under an accident condition, the multi-layer thin-walled plates of a limiting stopper are broken sequentially, which allows the torsion member to rotate in stages to consume vibration energy and slow the torsion speed, and allows the torsion member to be unloaded while torsion; the torsion member can automatically return to the initial state after unloading, so that the purpose of slowing and effectively unloading the horizontal force and torsion force is achieved; and therefore, the torsion effect is reduced, the safety of thepower transmission tower is improved, and the installation and maintenance are convenient.
本发明公开了一种铅芯橡胶扭转上升的输电塔，属于输电塔技术领域，包括主塔、低挂点单旋转臂、叠层铅芯橡胶钢板扭转支座和高挂点支架，所述主塔和高挂点支架之间固定连接有主塔双转轴，所述主塔双转轴上从上至下依次旋转连接有叠层铅芯橡胶钢板扭转支座和铰链连接装置，所述铰链连接装置通过螺栓固定连接有低挂点单旋转臂。在正常使用状态下，结构稳定耐用，在事故工况下，限位器的多层薄壁板依次断裂，允许受扭的构件的发生阶段性的旋转，消耗振动能量，减缓扭转速度，并允许受扭构件扭转的同时卸载，卸载后可以自动恢复到初始状态，达到缓慢、有效卸载水平力与扭转力的目的，减小扭转效应，提高输电塔的安全性，方便安装和维修。
