Earthquake resistant tower for power transmission line

KIM TAE HO

The present invention relates to an earthquake-resistant apparatus of a transmission tower of an extra-high-voltage overhead power transmission line, which reinforces the interior of a support structure when an impact or vibration is created by an earthquake or the like to protect and support a transmission tower installed on the corresponding support structure. More specifically, the earthquake-resistant apparatus of a transmission tower of an extra-high-voltage overhead power transmission line comprises: a roller member inserted into deposited ground in a prescribed depth and rotatably installed on a plurality of support structures which support a transmission tower with an overhead power transmission line; and an earthquake-resistant member which is wound on the outer surface of the roller member in a roller form, is unwound from the roller member rotated by a control signal of a control unit, and is inserted into an insertion hole drilled in the longitudinal direction of the support structures when unwound to improve the resistance of the support structures against vibration from an earthquake so as to protect the transmission tower.

본 발명은 지진 등에 의한 진동이나 충격이 발생시에 지지구조물 내부를 보강시켜 해당 지지구조물에 설치된 송전철탑을 보호 및 지지할 수 있는 초고압 가공송전선로 송전철탑의 내진장치에 대한 것으로, 더욱 상세하게는 타설된 지면에 소정깊이 삽입되되 가공송전선로가 구비된 송전철탑을 지지하는 복수의 지지구조물 상에 회전가능하게 설치되는 롤러부재 및 상기 롤러부재 외면에 두루마리 형태로 귄취되되 제어부의 제어신호에 의해 회전하는 상기 롤러부재에서 권출되며, 권출시에 상기 지지구조물의 길이방향으로 타공된 삽입공에 삽입되어 지진으로부터의 진동에 상기 지지구조물이 저항력을 향상시켜 상기 송전철탑을 보호하는 내진부재를 포함하는 것을 특징으로 한다.
