FALL PREVENTION DEVICE FOR RAILROAD WORK
To provide a fall prevention device for railroad work being easy to use during the work and including a connector having an excellent load bearing performance in a case of falling.SOLUTION: A fall prevention device for railroad work comprises a pedestal unit (11) being attachable/detachable with respect to a rail (100), a support (12) projecting upward from the pedestal unit 11, and a connector 50 provided on the support 12 and connecting a rope of a safety belt. The connector 50 includes a pair of connecting parts 51 and 52 projecting to both sides in the longitudinal direction of the rail with respect to a shaft part 40 of the support. The pair of connecting parts 51 and 52 respectively include a first linear portion and a second linear portion that are fixed to a lateral face 40b of the shaft part in an inclined arrangement at different height positions from each other. Further, the pair of connecting parts 51 and 52 are provided in an intersecting relation in which the inclination directions with respect to a reference plane perpendicular to the longitudinal direction of the shaft part 40 are opposite to each other.SELECTED DRAWING: Figure 1
【課題】作業時に使いやすく、落下時のコネクタ部の耐荷重性能に優れる鉄道作業用落下防止器具を提供する。【解決手段】レール１００に対して着脱可能な台座ユニット１１と、台座ユニット１１から上方に突出する支柱１２と、支柱１２に設けられて安全帯のロープを接続するコネクタ部５０とを有する。コネクタ部５０は、支柱のシャフト部４０に対して、レールの長手方向の両側に突出する一対の接続パーツ５１、５２を備える。一対の接続パーツ５１，５２はそれぞれ、第１の直線部及び第２の直線部が互いの高さ位置を異ならせた傾き配置で、シャフト部の側面４０ｂに第１の直線部及び第２の直線部が固定される。さらに一対の接続パーツ５１，５２は、シャフト部４０の長手方向と垂直な基準面に対する傾き方向が互いに逆である交差関係で設けられる。【選択図】図１
