Problems solved by technology

[0002] The transmission tower is a common high-rise structure, which is usually subjected to gravity load, wind load, earthquake load, etc. At the same time, various loads on the transmission line on the transmission tower are finally transmitted to the transmission tower. Under normal circumstances, The force generated by the transmission line on the transmission tower on the transmission tower is close to balance, so the transmission tower is only affected by the vertical force and a small part of the unbalanced force. However, when the accident occurs, the transmission line on the transmission tower When asymmetrical fracture occurs, the cable fracture is often an instant event, and its load characteristics have obvious impact load characteristics, which increases the damage to the structure; in addition, most of the transmission towers at the present stage need to have insulation requirements for the transmission mechanism. Larger insulation space, so there is often a first distance between the point of stress on the transmission line of the transmission tower and the centroid of the main tower of the transmission tower. After the torsion component rotates, the distance between the two ends of the transmission line decreases, and the transmission line relaxes. , falling under the action of gravity, there is a potential safety hazard. The transmission line after an asymmetric fracture will not only generate vertical loads but also horizontal loads on the transmission tower. In addition to increasing the structural stiffness and strength of the transmission tower structure, it can also be allowed The torsion member rotates to unload the load, but in normal state this rotation will affect the normal use

Abstract

The invention discloses a power transmission tower with lead-core rubber torsionally raised, belonging to the technical field of power transmission towers, comprising a main tower, a low hanging point single rotating arm, a laminated lead rubber steel plate torsion support and a high hanging point bracket. The tower and the high hanging point bracket are fixedly connected with the double shafts of the main tower, and the double shafts of the main tower are rotated sequentially from top to bottom, and are connected with a laminated lead rubber steel plate torsion support and a hinge connection device, and the hinge connection device Bolt-on single swivel arm with low hitch point. Under normal use conditions, the structure is stable and durable. Under accident conditions, the multi-layer thin-walled plates of the limiter are broken sequentially, allowing the torsion member to rotate in stages, consuming vibration energy, slowing down the torsional speed, and allowing The torsion member is unloaded while twisting, and can automatically return to the initial state after unloading, achieving the purpose of slowly and effectively unloading the horizontal force and torsional force, reducing the torsion effect, improving the safety of the transmission tower, and facilitating installation and maintenance.
