EXPANSION RAIL DEVICE FOR RAILWAY WORK VEHICLES
To provide an expansion rail device in which a push-up roller does not detach from a push-up lever when a movable rail is manually pulled up onto a fixed rail.SOLUTION: A push-up lever 8 is pushed by a push-up roller 5 and falls while retaining energizing means 9 when the movable rail 2 is in the extended position, and pushes the push-up roller 5 in to a standing position by releasing the energizing means 9 when a base end 2a of the movable rail 2 is in a position on a tip 1a of a fixed rail 1. Push-up means 4 assists the initial force when the movable rail 2 is retracted in the contraction direction. A stopper 10 is provided on webs 1d on the left and right sides of the tip 1a of the fixed rail 1 to regulate the movement range of the push-up roller 5 such that it does not exceed the turning radius of the push-up lever 8 when the movable rail 2 is manually pulled onto the fixed rail 1.SELECTED DRAWING: Figure 4
【課題】可動レールを固定レール上へ手動にて引き上げる際に、押上用ローラが押上レバーから外れることがない伸縮レール装置を提供する。【解決手段】押上レバー８は、可動レール２が伸長位置にあるとき、押上用ローラ５に押されて付勢手段９を畜勢しつつ転倒し、可動レール２の基端部２ａが固定レール１の先端部１ａ上に乗った位置にあるとき、付勢手段９の放勢により押上用ローラ５を押し上げて起立する。押上手段４により、可動レール２を収縮方向へ後退操作する際の初期の力を補助する。固定レール１の先端部１ａ側のウェブ１ｄの左右側面には、可動レール２を固定レール１上へ手動で引き上げる際に、押上用ローラ５が押上レバー８の回転半径を超えないように、その移動範囲を規制するためのストッパ１０が突設される。【選択図】図４
