To provide a rail lifting device that takes a large lifting stroke and corrects for this even when a track surface is not horizontal so that the rail can be lifted and lowered in the vertical direction.SOLUTION: A rail lifting device comprises: a tilt shaft 3a mounted on a base plate 1; a tilt frame 2 that can be tilted freely via a tilt mechanism 9 that is vertically attached to the end of the base plate 1; and a lifting frame 8 attached to the tilt frame 2 via a screw shaft 5.SELECTED DRAWING: Figure 1

    【課題】昇降ストロークを大きくとるとともに、道床面が水平でない場合にもこれを補正して鉛直方向に昇降を行なえるようにしたレールの持ち上げ装置を提供する。【解決手段】ベースプレート1上に取り付けた傾動軸3aと,ベースプレート1の端部に垂直方向に取り付けられた傾動機構9を介して傾動自在とした傾動フレーム2と、この傾動フレーム2にネジ軸5を介して取り付けられた昇降フレーム8とでレール持ち上げ装置を構成する。【選択図】図1
