Abstract

[Problem] To provide an extending and contracting rail device in which an upward-pushing roller does not detach from an upward-pushing lever when manually raising a movable rail onto a fixed rail. [Solution] When a movable rail 2 is in an extended position, an upward-pushing lever 8 is pushed by an upward-pushing roller 5 and stores energy in an energy-storing means 9 while falling, and when a base end part 2a of the movable rail 2 is positioned so as to be mounted on a tip end part 1a of a fixed rail 1, the upward-pushing lever 8 rises and pushes up the upward-pushing roller 5 by means of energy released from the energy-storing means 9. Initial force for when the movable rail 2 is retracted in a contraction direction is supplemented by means of an upward-pushing means 4. A stopper 10 for restricting the range of movement of the upward-pushing roller 5 projects out from left and right side surfaces of a web 1d on a tip end part 1a side of the fixed rail 1, so that said upward-pushing roller 5 does not exceed the radius of rotation of the upward-pushing lever 8 when the movable rail 2 is manually raised onto the fixed rail 1.

It is about.
　従来、鉄道作業車両用の伸縮レール装置として、例えば特許文献１に記載されたものが知られている。これは、作業車両の保管場所に固定された固定レールの上に載せ置かれた可動レールを、必要時に引き出して所定位置まで延長する形式のものである。
　この伸縮レール装置においては、固定レールが、本線レールに対しほぼ直交方向に伸びるように保管場所のベース上に固定される。可動レールは、基端側を固定レールの基端部上にまた先端側を固定レールの先端部上に配置して固定レール上に載せ置かれる収縮位置と、基端側が固定レールの先端側と上面を一致させて延線方向である前後方向に固定レールと連続する伸長位置との間で固定レールの上をそれの延線方向である前後方向に往復移動可能に設けられる。
　固定レールは、作業車両の車輪を載せ受ける上部フランジと、ベースに固定される下部フランジと、両フランジの中央間を接続する垂直のウェブとを具備する。
　可動レールは、作業車両の車輪を載せ受ける走行部と、当該走行部の左右両側から相対向して下方へ延出する一対の脚部とを有し、全体が断面ほぼコ字状に構成され、収縮位置において走行部を固定レールの上部フランジ上に乗せ、固定レールを跨いで固定レール上に載せ置くことができるように構成される。

　押上手段により、可動レールを収縮方向へ後退操作する際の初期の力を押上機構で補助するように構成される。 Conventionally, as a telescopic rail device for a railway work vehicle, for example, the one described in Patent Document 1 is known. This is a form in which a movable rail placed on a fixed rail fixed to a storage place of a work vehicle is pulled out when necessary and extended to a predetermined position.
In this telescopic rail device, the fixed rail is fixed on the base of the storage place so as to extend in a direction substantially orthogonal to the main rail. The movable rail has a contraction position in which the base end side is placed on the base end portion of the fixed rail and the tip end side is placed on the tip end portion of the fixed rail and is placed on the fixed rail, and the base end side is the tip end side of the fixed rail. It is provided so that the upper surfaces can be matched and reciprocated between the fixed rail and the continuous extension position in the front-rear direction, which is the extension direction, on the fixed rail in the front-rear direction, which is the extension direction.
The fixed rail comprises an upper flange on which the wheels of the work vehicle are placed, a lower flange fixed to the base, and a vertical web connecting the centers of both flanges.
The movable rail has a traveling portion on which the wheels of the work vehicle are placed and a pair of legs extending downward from both the left and right sides of the traveling portion, and the entire structure is substantially U-shaped in cross section. In the contracted position, the traveling portion is placed on the upper flange of the fixed rail so that the traveling portion can be placed on the fixed rail straddling the fixed rail.
Support plates extending so as to face the left and right side surfaces of the web on the tip end side of the fixed rail at the extended position are fixed to the legs on the base end side of the movable rail.
Between the fixed rail and the movable rail, a pushing means for pushing up the base end side of the movable rail onto the tip of the fixed rail when retracting the movable rail in the extended position is provided.
The push-up means includes a push-up roller provided on the support plate so as to project outward on the opposite side of the support plate in the opposite direction, and the base end side of the movable rail in the extended position retracts to the tip of the fixed rail. It is provided with a push-up mechanism provided on both the left and right sides of the tip side of the fixed rail so as to engage with the push-up roller and apply a force to push up the base end side of the movable rail upward until it rides on.
The push-up mechanism includes a push-up lever that engages with a push-up roller to stand up and overturn, and an urging means that constantly rotates and urges the push-up lever in the standing direction.
When the movable rail is in the extended position, the push-up lever is pushed by the push-up roller and falls while energizing the urging means, and the base end of the movable rail is on the tip of the fixed rail. At that time, the push-up roller is pushed up by the release of the urging means and urged by the urging means so as to stand up.
The push-up means is configured to assist the initial force when the movable rail is retracted in the contraction direction by the push-up mechanism.

　上記従来の伸縮レール装置においては、伸長状態にある可動レールを収縮位置に復旧させるために、可動レールの基端側を固定レールの先端部上へ手動にて引き上げる際に、勢い余って、押上用ローラが押上レバーの回転半径を超える位置まで引き上げられると、押上用ローラと押上レバーとの係合が外れてしまう。可動レールは大重量であるから、いったん係合が外れた押上用ローラを適正位置に戻すのは容易でないという問題点がある。
　したがって、この発明は、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の回転半径を超えて引き上げられることがない伸縮レール装置を提供することを課題とする。 In the above-mentioned conventional telescopic rail device, in order to restore the movable rail in the extended state to the contracted position, when the base end side of the movable rail is manually pulled up onto the tip of the fixed rail, the force is excessively pushed up. If the push-up roller is pulled up to a position exceeding the turning radius of the push-up lever, the push-up roller and the push-up lever will be disengaged. Since the movable rail is heavy, there is a problem that it is not easy to return the push-up roller once disengaged to an appropriate position.
Therefore, an object of the present invention is to provide a telescopic rail device in which the push-up roller is not pulled up beyond the turning radius of the push-up lever when the movable rail is manually pulled up onto the fixed rail.
　上記課題を解決するための、本発明の伸縮レール装置は、可動レール２が、作業車両の車輪を載せ受ける走行部２ｂと、当該走行部２ｂの左右両側から相対向して下方へ延出する一対の脚部２ｃとを有し、全体が断面ほぼコ字状に構成され、収縮位置において走行部２ｂを固定レール１の上部フランジ１ｂ上に乗せ、固定レール１を跨いで固定レール１上に載せ置くことができるように構成される。可動レール２の基端部２ａ側の脚部２ｃには、伸長位置において固定レール１の先端部１ａ側のウェブ１ｄの左右側面に対向するように延出する支持板３がそれぞれ固着される。固定レール１と可動レール２との間には、伸長位置にある可動レール２を後退させる際に可動レール２の基端部２ａ側を固定レール１の先端部１ａ上に押し上げるための押上手段４が設けられる。押上手段４は、支持板３の対向方向と反対側である外側へ突出するように支持板３上に設けられる押上用ローラ５と、伸長位置にある可動レール２の基端部２ａが後退して固定レール１の先端部１ａ上に乗り上げるまでの間、押上用ローラ５に係合して可動レール２の基端部２ａ側を上方へ押し上げる力を付与するように固定レール１の先端側の左右両側に設けられる押上機構６とを具備する。押上機構６は、押上用ローラ５に係合して起立・転倒する押上レバー８と、この押上レバー８を常時起立方向に回転付勢する付勢手段９とを具備する。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ように付勢手段９により付勢される。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押上手段４で補助するように構成される。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の基端側を固定レール１の先端部上へ手動にて引き上げる際に、押上用ローラ５が押上レバー８の回転半径を超えて引き上げられることがないように、それの移動範囲を規制するためのストッパ１０が突設される。 In the telescopic rail device of the present invention for solving the above problems, the movable rail 2 extends downward from both the left and right sides of the traveling portion 2b on which the wheels of the work vehicle are placed and the left and right sides of the traveling portion 2b. It has a pair of leg portions 2c and is configured to have a substantially U-shaped cross section as a whole. At the contracted position, the traveling portion 2b is placed on the upper flange 1b of the fixed rail 1 and straddles the fixed rail 1 on the fixed rail 1. It is configured so that it can be placed. A support plate 3 extending so as to face the left and right side surfaces of the web 1d on the tip end portion 1a side of the fixed rail 1 at the extended position is fixed to the leg portion 2c on the base end portion 2a side of the movable rail 2. A push-up means 4 between the fixed rail 1 and the movable rail 2 for pushing up the base end portion 2a side of the movable rail 2 onto the tip end portion 1a of the fixed rail 1 when the movable rail 2 in the extended position is retracted. Is provided. In the push-up means 4, the push-up roller 5 provided on the support plate 3 so as to project outward on the opposite side of the support plate 3 from the opposite direction, and the base end portion 2a of the movable rail 2 at the extended position retract. The tip side of the fixed rail 1 is engaged with the push-up roller 5 to give a force to push up the base end 2a side of the movable rail 2 until it rides on the tip 1a of the fixed rail 1. It is provided with push-up mechanisms 6 provided on both the left and right sides. The push-up mechanism 6 includes a push-up lever 8 that engages with the push-up roller 5 to stand up and overturn, and an urging means 9 that constantly rotates and urges the push-up lever 8 in the standing direction. When the movable rail 2 is in the extended position, the push-up lever 8 is pushed by the push-up roller 5 and falls while energizing the urging means 9, and the base end portion of the movable rail 2 is the tip portion 1a of the fixed rail 1. When it is in the upper position, it is urged by the urging means 9 so as to push up the push-up roller 5 and stand up by the release of the urging means 9. The push-up means 4 is configured to assist the initial force when the movable rail 2 is retracted in the contraction direction. On the left and right side surfaces of the web 1d on the tip 1a side of the fixed rail 1, a push-up roller 5 rotates the push-up lever 8 when the base end side of the movable rail 2 is manually pulled up onto the tip of the fixed rail 1. A stopper 10 is provided to regulate the range of movement of the stopper 10 so that the rail is not pulled up beyond the radius.
　本発明の伸縮レール装置においては、押し上げ用ローラ５の移動範囲がストッパ１０により規制されるため、可動レール２を固定レール１上へ手動にて引き上げる際に、押上用ローラ５が押上レバー８の回転半径を超えて引き上げられることがなく、押し上げ用ローラ５が押上レバー８から外れることがない。 In the telescopic rail device of the present invention, the moving range of the push-up roller 5 is regulated by the stopper 10. Therefore, when the movable rail 2 is manually pulled up onto the fixed rail 1, the push-up roller 5 moves to the push-up lever 8. The push-up roller 5 does not come off from the push-up lever 8 without being pulled up beyond the turning radius.
