To provide a technique capable of simplifying an operation for climbing over an iron tower in a self-traveling electric wire inspection device.SOLUTION: A self-traveling electric wire inspection device performing an inspection of an electric wire, while running along an overhead ground wire wired to iron towers, comprises: a running part capable of running on the overhead ground wire; a main body part arranged downstream of the running part; an arc-shaped arm coupled to the main body part so as to be relatively moved, and forming a bypass for moving the main body part so as to bypass each iron tower; and a pair of hook mechanisms provided to both end sides while interposing an intermediate part in a length direction of the arm for hooking the arm to the overhead ground wire. Each of the pair of hook mechanism is structured so as to have an open part into which the overhead ground wire can enter and exit, and to enable the movement of an entrance into/from which the overhead ground of the open part enters and exits to the other direction opposite to one side without directing it to a vertical direction from the direction of a horizontal direction.SELECTED DRAWING: Figure 1
【課題】自走式電線点検装置が鉄塔を乗り越える動作を簡略化させることができる技術を提供する。【解決手段】鉄塔間に架線された架空地線に沿って走行しながら電線の点検を行う自走式電線点検装置であって、架空地線上を走行可能な走行部と、走行部の下方に配置される本体部と、本体部に対して相対移動可能に連結され、鉄塔を迂回するように本体部を移動させるための迂回路を形成する円弧型のアームと、アームを架空地線に懸垂させるためにアームの長さ方向の中間部を挟んで両端側に設けられる一対のフック機構と、を備え、一対のフック機構のそれぞれは、架空地線が出入り可能な開口部を有し、該開口部のうち架空地線が出入りする出入口を水平方向の一方から鉛直上方に向けずに一方と反対側の他方へ移動させることが可能に構成される。【選択図】図1
