特開7−329781号公報Japanese Patent Laid-Open No. 7-329781

上記従来の伸縮レール装置においては、通常モータにより可動レールを伸縮駆動するが、伸長状態で停電や電源故障などによりモータを使用できない場合、可動レールを元位置に収納するのに手動のウィンチを使用しなければならないが、ワイヤロープを準備し可動レールに接続する等の対応作業が大がかりになる。
したがって、この出願に係る発明は、モータの駆動電源が喪失した場合等の非常時でも、伸長した可動レールを手動で簡易に元位置に戻す操作が可能な伸縮レール装置の手動操作用キー装置を提供することを目的とする。
In the conventional telescopic rail device, the movable rail is normally extended and retracted by a motor. If the motor cannot be used due to a power failure or power failure in the extended state, a manual winch is used to store the movable rail in its original position. However, the handling work such as preparing the wire rope and connecting it to the movable rail becomes a major issue.
Therefore, the invention according to this application provides a key device for manual operation of a telescopic rail device that can easily return an extended movable rail to its original position even in an emergency such as when the motor drive power is lost. The purpose is to provide.

上記課題を解決するための、この出願に係る発明の伸縮レール装置の手動操作用キー装置は、鉄道線路の側部に設けられた保管場所の基礎レール1から可動レール2を長さ方向に延長させて作業車両を鉄道線路の本線レールに移動させるために基礎レール1上で可動レール2を移動させる可動レール移動手段3を備え、可動レール移動手段3には、基礎レール1に固定されたモータ4と、モータ4に駆動される駆動スプロケット5と、駆動スプロケット5に掛け回され可動レールに係止されるチェーン7と、モータ4の軸に直交する方向に駆動力を伝達する円筒状の駆動軸10と、この駆動軸10を相対回転自在に長手方向に貫通するスプロケット軸11とを具備させる。キー部材12を駆動軸10及びスプロケット軸11の周方向対応位置に備えたキー溝10a,11aにそれぞれ係合させ、駆動軸のキー溝10aから離脱可能に両者を結合する。   The key device for manual operation of the telescopic rail device of the invention according to this application for solving the above-mentioned problem extends the movable rail 2 in the length direction from the base rail 1 of the storage place provided on the side of the railway track. In order to move the work vehicle to the main rail of the railroad track, a movable rail moving means 3 for moving the movable rail 2 on the basic rail 1 is provided, and the movable rail moving means 3 includes a motor fixed to the basic rail 1. 4, a drive sprocket 5 driven by the motor 4, a chain 7 hung around the drive sprocket 5 and locked to a movable rail, and a cylindrical drive that transmits a driving force in a direction perpendicular to the axis of the motor 4 A shaft 10 and a sprocket shaft 11 that penetrates the drive shaft 10 in the longitudinal direction so as to be relatively rotatable are provided. The key member 12 is engaged with key grooves 10a and 11a provided at positions corresponding to the circumferential direction of the drive shaft 10 and the sprocket shaft 11, respectively, and both are detachably coupled to the key groove 10a of the drive shaft.

この出願に係る発明の伸縮レール装置のキー装置によれば、常時はモータにより可動レールを伸縮駆動操作できるが、伸長時にモータの駆動電源が喪失しても、キー部材駆動軸から離脱させれば、スプロケット軸を手動で回転操作することができ、スプロケットに掛けたチェーンを引き回して可動レールを移動させ簡易に元位置に戻すことができる。   According to the key device of the telescopic rail device of the invention according to this application, the movable rail can be extended and driven at all times by a motor, but if the motor drive power is lost during the extension, it can be separated from the key member drive shaft. The sprocket shaft can be manually rotated, and the chain hung on the sprocket can be drawn to move the movable rail to easily return to the original position.

図面を参照して本発明の実施の一形態を説明する。
なお、伸縮レール装置は、全体を図示しないが、従来のものと同様にして、作業車両の保管場所のベース上に鉄道線路とほぼ直交方向に敷設され、可動レールが保管場所にある元位置から、鉄道線路上へ延出した前進位置まで、基礎レール上を駆動装置により往復移動自在に設けられる。また、基礎レールは、保管場所PのベースB上に設けられる補助レール上を元位置から、前進位置まで、駆動装置により往復移動自在に設けられる。
An embodiment of the present invention will be described with reference to the drawings.
The telescopic rail device is not shown in its entirety, but it is laid in a direction substantially orthogonal to the railway track on the base of the storage location of the work vehicle in the same manner as the conventional one, and the movable rail is from the original position at the storage location. The base rail is provided so as to be reciprocally movable by a driving device up to a forward position extending on the railroad track. The foundation rail is provided on the auxiliary rail provided on the base B of the storage place P so as to be reciprocally movable from the original position to the advance position by a drive device.

図1,図2において、可動レール2は、ほぼ断面コ字状を成し、縮小状態の元位置において、基礎レール1の上に載せ置かれる。可動レール2は、基礎レール1の下部の所要個所に取付けられたローラ1aに乗っており、基礎レール1上を軸線方向に移動可能である。可動レール2は、前進位置において、基端が基礎レール1の先端に連続して鉄道線路上へ延出する。基礎レール1には、可動レール2を軸線方向に往復移動させるための駆動装置3を備えている。   1 and 2, the movable rail 2 has a substantially U-shaped cross section and is placed on the base rail 1 at the original position in the contracted state. The movable rail 2 rides on a roller 1a attached to a required position below the foundation rail 1, and can move on the foundation rail 1 in the axial direction. In the forward movement position, the movable rail 2 extends on the railroad track with the base end continuous to the tip of the foundation rail 1. The base rail 1 is provided with a driving device 3 for reciprocating the movable rail 2 in the axial direction.

図1ないし図3に示すように、駆動装置3は、基礎レール1の基端側に固定されたモータ4と、モータ4の近傍の駆動スプロケット5と、基礎レール1の先端側に固定された従動スプロケット6と、これらのスプロケット5,6間に掛け回されるチェーン7とを具備する。チェーン7は、基礎レール1と可動レール2との間に形成された空間を通して張られ、途上の係止金具8により可動レール2の基端部に係止される。   As shown in FIGS. 1 to 3, the driving device 3 is fixed to the motor 4 fixed to the base end side of the foundation rail 1, the drive sprocket 5 near the motor 4, and the tip side of the foundation rail 1. A driven sprocket 6 and a chain 7 hung between the sprockets 5 and 6 are provided. The chain 7 is stretched through a space formed between the base rail 1 and the movable rail 2, and is locked to the base end portion of the movable rail 2 by an intermediate locking fitting 8.

図4ないし図6に示すように、駆動スプロケット5のスプロケット軸11は、モータ4に付属する減速機によりモータ軸と直交方向に回転を伝達する駆動軸10にキー装置12を介して結合する。スプロケット軸11は、円筒軸である駆動軸10に軸線回りに相対回転自在に挿入され、露出した一端部には軸回りにキー装置12が装着され、同じく露出した他端部には駆動スプロケット5を手動回転させるためのハンドル13を装着可能である。   As shown in FIGS. 4 to 6, the sprocket shaft 11 of the drive sprocket 5 is coupled via a key device 12 to a drive shaft 10 that transmits rotation in a direction orthogonal to the motor shaft by a reduction gear attached to the motor 4. The sprocket shaft 11 is inserted into a drive shaft 10 which is a cylindrical shaft so as to be relatively rotatable around an axis, and a key device 12 is mounted around one end of the exposed shaft and the drive sprocket 5 is mounted at the other exposed end. A handle 13 for manually rotating can be mounted.

キー装置12は、駆動軸10とスプロケット軸11とを結合するキー片14と、このキー片14の基端部を支持し、スプロケット軸11を貫通させる支持部材15と、支持部材15に隣接してスプロケット軸11を挿通させるナット部材16とを具備する。キー片14は、駆動軸10及びスプロケット軸11の周方向対応位置に設けられたキー溝10a,11aに嵌合する角棒材である。   The key device 12 includes a key piece 14 that couples the drive shaft 10 and the sprocket shaft 11, a support member 15 that supports the base end portion of the key piece 14 and penetrates the sprocket shaft 11, and is adjacent to the support member 15. And a nut member 16 through which the sprocket shaft 11 is inserted. The key piece 14 is a square bar material that is fitted into key grooves 10 a and 11 a provided at positions corresponding to the circumferential direction of the drive shaft 10 and the sprocket shaft 11.

支持部材15は、スプロケット軸11の一端部を軸方向摺動自由に貫通させる貫通孔15aを備えた環状体であり、スプロケット軸11の途上の大径のストッパリング11cを受け入れる凹部15bが貫通孔15aに連続している。支持部材15は、凹部15bの内周面にキー片14の基端部をねじ止めして、キー片14を軸方向に延出させる。支持部材15の外周側面に環状溝15cを備える。   The support member 15 is an annular body provided with a through-hole 15a that allows one end of the sprocket shaft 11 to freely slide in the axial direction, and a concave portion 15b that receives a large-diameter stopper ring 11c in the middle of the sprocket shaft 11 has a through-hole. It is continuous to 15a. The support member 15 screws the base end portion of the key piece 14 to the inner peripheral surface of the recess 15b to extend the key piece 14 in the axial direction. An annular groove 15 c is provided on the outer peripheral side surface of the support member 15.

ナット部材16は、スプロケット軸11の端部に形成されたねじ部11bに螺合する環状体であり、正逆回転によりスプロケット軸11上を支持部材15と共に軸線方向前後に移動可能である。ナット部材16は、外周面に半径方向に延びる4本の摘み16aを周方向等間隔に備える。ナット部材16の一方の外周縁部は、軸方向に支持部材15上に延出して、内側に向かって環状溝15c内に突出し支持部材15に係合する環状係合部16bを備える。環状係合部16bは、環状溝15cに対し幅方向に遊びをもって緩く係合する。ナット部材16には、支持部材15を離す方向に付勢し、キー片14がスプロケット軸11のキー溝11aに合致すると、支持部材15をナット部材16から押し出す軸方向のプランジャ17が軸周り等間隔に4箇所埋設されている。   The nut member 16 is an annular body that is screwed into a threaded portion 11b formed at the end of the sprocket shaft 11, and can move forward and backward along the sprocket shaft 11 along with the support member 15 by forward and reverse rotation. The nut member 16 includes four knobs 16a extending in the radial direction on the outer peripheral surface at equal intervals in the circumferential direction. One outer peripheral edge portion of the nut member 16 includes an annular engagement portion 16b that extends in the axial direction on the support member 15 and projects inward into the annular groove 15c to engage with the support member 15. The annular engagement portion 16b is loosely engaged with the annular groove 15c with play in the width direction. When the nut member 16 is urged in the direction in which the support member 15 is released and the key piece 14 matches the key groove 11a of the sprocket shaft 11, an axial plunger 17 that pushes the support member 15 out of the nut member 16 is rotated around the axis. Four places are buried in the interval.

この鉄道作業車両用の伸縮レール装置は、可動レール2の延長位置において、何らかの原因でモータ4の電源が消失した場合、スプロケット軸11の端部にハンドル13を装着し、駆動スプロケット5を手動回転させてチェーン7を引き回し可動レール2を保管場所Pに戻す。この手動操作に先立ち、モータ4の負荷を遮断するため駆動軸10からスプロケット軸11を分離する。スプロケット軸11のキー溝11aにキー片14が係合する状態で(図5)装着してあるキー装置12のナット部材16を回転させると、スプロケット軸11上を外側に向かってナット部材16が環状係合部16bに係合している支持部材15と共に移動していく。支持部材15の移動途上で、キー片14が駆動軸10のキー溝10aから離脱すれば(図7)、スプロケット軸11と駆動軸10とが分離するから、スプロケット軸11の他端部のハンドル13でスプロケット軸11を回転操作でき、駆動スプロケット5が回転してチェーン7を引き回し可動レール2を基礎レール1上で移動させることができる。   This telescopic rail device for a railroad work vehicle has a handle 13 attached to the end of the sprocket shaft 11 and manually rotates the drive sprocket 5 when the power of the motor 4 disappears for some reason at the extended position of the movable rail 2. Then, the chain 7 is pulled and the movable rail 2 is returned to the storage place P. Prior to this manual operation, the sprocket shaft 11 is separated from the drive shaft 10 in order to cut off the load of the motor 4. When the nut member 16 of the key device 12 mounted in the state where the key piece 14 is engaged with the key groove 11a of the sprocket shaft 11 (FIG. 5) is rotated, the nut member 16 is moved outward on the sprocket shaft 11. It moves together with the support member 15 engaged with the annular engagement portion 16b. If the key piece 14 is detached from the key groove 10a of the drive shaft 10 during the movement of the support member 15 (FIG. 7), the sprocket shaft 11 and the drive shaft 10 are separated from each other. 13, the sprocket shaft 11 can be rotated, and the drive sprocket 5 can be rotated to draw the chain 7 and move the movable rail 2 on the foundation rail 1.

電源が復旧してモータ4により可動レール2を駆動する場合、操作に先立ち、モータ4の駆動力を伝達可能に駆動軸10とスプロケット軸11とをキー装置12で結合する。キー装置12はスプロケット軸11のキー溝11aにキー片14を係合させている状態にある(図7)から、ナット部材16を回転させると、ナット部材16は環状係合部16bに係合している支持部材15と共にスプロケット軸11上を内側に向かって移動していく。キー片14が駆動軸10の端面に当接して、支持部材15の移動が妨げられたら、以降のナット部材16の回転によりプランジャ17が押し込まれるが、スプロケット軸11を駆動軸10に対して相対回転させ、駆動軸10のキー溝10aがスプロケット軸11のキー溝11aに合致すれば、キー片14が受け入れられて支持部材15がフリーになるため、プランジャ17が飛び出して、環状溝15c内の環状係合部16bの遊び分だけ支持部材15をナット部材16から押し出し、キー片14を駆動軸10のキー溝10aに押し込み、キー溝10aにキー片14を位置決めする。さらにナット部材16を回転させて支持部材15の凹部15bにストッパリング11cを受け入れると、駆動軸10とスプロケット軸11とがキー片14で結合し、モータ4の駆動力をスプロケット5に伝達できる。   When the power supply is restored and the movable rail 2 is driven by the motor 4, the drive shaft 10 and the sprocket shaft 11 are coupled by the key device 12 so that the driving force of the motor 4 can be transmitted prior to the operation. Since the key device 12 is in a state where the key piece 14 is engaged with the key groove 11a of the sprocket shaft 11 (FIG. 7), when the nut member 16 is rotated, the nut member 16 is engaged with the annular engagement portion 16b. The sprocket shaft 11 is moved inward along with the supporting member 15 that is being operated. When the key piece 14 comes into contact with the end surface of the drive shaft 10 and the movement of the support member 15 is hindered, the plunger 17 is pushed in by the subsequent rotation of the nut member 16, but the sprocket shaft 11 is relative to the drive shaft 10. When the key groove 10a of the drive shaft 10 coincides with the key groove 11a of the sprocket shaft 11, the key piece 14 is received and the support member 15 becomes free, so that the plunger 17 pops out, and the inside of the annular groove 15c. The support member 15 is pushed out from the nut member 16 by the amount of play of the annular engagement portion 16b, the key piece 14 is pushed into the key groove 10a of the drive shaft 10, and the key piece 14 is positioned in the key groove 10a. When the nut member 16 is further rotated to receive the stopper ring 11 c in the recess 15 b of the support member 15, the drive shaft 10 and the sprocket shaft 11 are coupled by the key piece 14, and the driving force of the motor 4 can be transmitted to the sprocket 5.
