FALL PREVENTION DEVICE FOR RAILROAD WORK
To provide a fall prevention device for railroad work, being easily attached to and detached from a rail, having high strength in a state attached to the rail, and being easy for workers to use.SOLUTION: A fall prevention device for railroad work comprises a pedestal unit (11) being attachable/detachable with respect to a rail (100), and a support (12) being attachable/detachable with respect to the pedestal unit. The pedestal unit includes a pair of side plates (21 and 22) located on both sides in the width direction of the rail and supporting guide members (25 and 26) in contact with a lateral face of the rail, and a top plate (20) located above the rail and connecting the pair of side plates, where one of the pair of side plates is a movable side plate (22) being openable/closable laterally in a width direction of the rail. The support includes a shaft part (40) projecting upward from the top plate, with it attached to the pedestal unit, and a holding part (41) for holding and clamping the pair of side plates from width-directional both sides of the rail to close the movable side plate.SELECTED DRAWING: Figure 2
【課題】レールへの着脱を行いやすく、レールへの取り付け状態での強度が高く、作業者が使用しやすい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、台座ユニットに対して着脱可能な支柱（１２）とを有する。台座ユニットは、レールの幅方向の両側に位置してレールの側面に接触するガイド部材（２５、２６）を支持する一対の側板部（２１、２２）と、レールの上方に位置して一対の側板部を接続する天板部（２０）とを有し、一対の側板部の一方はレールの幅方向の側方に開閉可能な可動側板部（２２）である。支柱は、台座ユニットに取り付けた状態で、天板部から上方に突出するシャフト部（４０）と、一対の側板部をレールの幅方向の両側から挟んで保持して可動側板部を閉じさせる保持部（４１）とを備える。【選択図】図２
