Description

本発明は、例えば、鉄道線路のレール交替のために新レールを現場（若しくはその近傍）に搬送するために用いるレール運搬用トロのレール積卸し装置に関するものである。   The present invention relates to a rail unloading device for a rail transporting trowel used for transporting a new rail to the site (or the vicinity thereof) for replacement of a railroad rail.

荷台に支柱を立設し、該支柱に片持ち梁状に支持させた横杆に、前記荷台（に設けた載置台）上のレールの積卸しを行うチェーンブロックを移動自在に組付け、チェーンブロックを用いてレールの積卸し作業を行うようにした構造のものは、具体例を挙げるまでもなく、公知である。   A chain block for loading and unloading rails on the loading platform (mounting platform provided on the loading platform) is movably assembled on a horizontal rail supported on the supporting column in a cantilevered manner. A structure in which rails are loaded and unloaded using blocks is well known, not to mention a specific example.

然しながら、この従来例は横杆の長さによって、チェーンブロックの移動範囲が制約を受け、路床の傾斜等現場の状況によって荷台（トロ）の近傍においてしか当該積卸しを行えなくなることがあり、積卸すに不適切であるため該作業を中止しなければならないことがある。   However, in this conventional example, the range of movement of the chain block is restricted by the length of the reed, and the unloading may be performed only in the vicinity of the loading platform (Tro) depending on the situation of the site such as the inclination of the roadbed, The work may have to be stopped because it is inappropriate for unloading.

このため、前記横杆に伸縮杆を組合わせ、この伸縮杆にチェーンブロックを組付け、伸縮杆の横杆からの突出量分長くしてチェーンブロックの荷台からの離開距離を伸ばせるようにした構造のものが、前記従来例の欠点を解決する手段として提案された（例えば、特許文献１）。   For this reason, a structure in which an expansion rod is combined with the horizontal rod, a chain block is combined with the expansion rod, and the length of the extension of the chain block from the loading platform is increased by extending the protruding amount of the expansion rod from the horizontal rod. Has been proposed as means for solving the disadvantages of the conventional example (for example, Patent Document 1).

特開平８−３２６００２号公報JP-A-8-32002

前記伸縮杆を用いた構造のものは、伸縮杆を横杆に並べて配設する分、荷台（レール運搬用トロ）の上部側が重くなり、殊に、伸縮杆を伸展した際にバランスが悪くなり、そのため、アウトリガを必要とし、積卸し作業としてアウトリガを用いることのできる現場ということが条件になり、必ずしも、初期の目的を達成できる構造のものとはいえない。   In the structure using the expansion rod, the upper side of the loading platform (rail transport toro) becomes heavy because the expansion rods are arranged side by side, especially when the expansion rod is extended, the balance becomes worse. Therefore, an outrigger is required, and it is a condition that the outrigger can be used as a loading / unloading operation, and it is not necessarily a structure that can achieve the initial purpose.

本発明は、結果的にはチェーンブロックの荷台からの離開距離を延ばせ、しかも、現場状況の制約のないレール積卸し装置を提供することを目的として創案したものである。   As a result, the present invention has been developed for the purpose of providing a rail unloading apparatus that can extend the separation distance of the chain block from the loading platform and that is free from restrictions on the site conditions.

荷台に支柱を立設し、該支柱に片持ち梁状に支持させた横杆に、前記荷台上のレールの積卸しを行うチェーンブロックを移動自在に組付けたレール運搬用トロのレール積卸し装置において、前記荷台に、前記レールの載置面より下側にしてシリンダ装置等の伸縮操作装置を設け、該伸縮操作装置によって進退する進退杆の先端に、前記レールを吊下げた、前記チェーンブロックのチェーンの押圧子を設けた、構成としたものである。   Rail loading / unloading of a rail transporting trolley in which a chain block for loading and unloading rails on the loading platform is movably assembled on a horizontal pole that is supported on the column in a cantilevered manner. In the apparatus, the chain is provided with an expansion / contraction operation device such as a cylinder device below the mounting surface of the rail, and the rail is suspended from a forward / backward end of the advance / retreat by the expansion / contraction operation device. A block chain pressing element is provided.

本発明によれば、レールを吊下したチェーンブロックのチェーンに対して、いわば直交する方向に進退する進退杆の先端の押圧子がこれを押圧するから、レールのチェーンによる吊下支点位置がトロ（荷台）から離開する方向に移動し、レールを卸すに適当な位置を前記進退杆の進退によって自在に選択することができ、実用的である。   According to the present invention, since the pusher at the tip of the advancing / retreating rod that advances / retreats in a direction orthogonal to the chain of the chain block that suspends the rail presses the chain, the suspension fulcrum position by the rail chain is It moves in the direction of separating from the (loading platform), and an appropriate position for unloading the rail can be freely selected by the advance / retreat of the advance / retreat, which is practical.

図面は、本発明に係るレール運搬用トロのレール積卸し装置の一実施例を示し、図１は正面図、図２は図１の一部欠截拡大図、図３は図２の平面図である。   The drawings show one embodiment of a rail unloading device for a rail transporting tro according to the present invention, FIG. 1 is a front view, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. 3 is a plan view of FIG. It is.

図中、１はレール運搬用トロで、トロ１は台車２上に荷台３を装置し、該荷台３上の適所にレール載置台４を並設し、レール載置台４の一端に支柱５を立設し、支柱５に片持梁状にして支持させ横杆６にチェーンブロック７を該横杆６に沿わせて移動自在に組付けて、レール積卸し装置付のトロとして構成したものである。なお、前記レール載置台４は、荷台３の前後方向に適宜数並べて配置し、長手方向の中央に配した軸（図示）を中心に回動させて前記のチェーンブロック７を荷台３（トロ１）の左右勝手自在に位置変更できるようにしてある。   In the figure, reference numeral 1 denotes a rail transporting toro, and the toro 1 has a loading platform 3 on a carriage 2, a rail mounting table 4 is juxtaposed at an appropriate position on the loading platform 3, and a column 5 is attached to one end of the rail mounting table 4. Standing up and supporting it in the form of a cantilever beam on a support column 5, a chain block 7 is assembled to the side rail 6 along the side rail 6 so that it can move freely. is there. The rail mounting table 4 is arranged in an appropriate number in the front-rear direction of the loading platform 3 and is rotated about an axis (illustrated) arranged in the center in the longitudinal direction to place the chain block 7 on the loading platform 3 (Toro 1). The position can be changed freely.

レール載置台４の一端に立設した前記支柱５の上端と、支柱５に基端を揺動可能に支持させた前記横杆６の中間部との間にはシリンダ装置８を配し、シリンダ装置８によって前記チェーンブロック７の位置調節を行えるようになっている。   A cylinder device 8 is disposed between the upper end of the support column 5 erected at one end of the rail mounting table 4 and the intermediate portion of the horizontal bar 6 whose base end is swingably supported by the support column 5. The device 8 can adjust the position of the chain block 7.

レール載置台４は、また、上面に受板４ａを備え、レールＲは該受板４ａを介して荷台３に積卸しされる。   The rail mounting table 4 also includes a receiving plate 4a on the upper surface, and the rail R is loaded and unloaded on the loading platform 3 through the receiving plate 4a.

レールＲの載置面を成す受板４ａの下側には、断面溝形前記載置台４内に収容するようにしてシリンダ装置９を設け、該シリンダ装置９のピストン棒９ａに接続した進退杆１０を前記荷台３の前記支柱５側の一側に対する他の一側側に配して案内兼用の支持筒１１に貫通支持させ、支持筒１１より突出する進退杆１０の先端に横軸１２ａによって回動自在にして該進退杆１０に支持させたローラ１２ｂより成る押圧子１２を設けてある。   A cylinder device 9 is provided below the receiving plate 4a forming the mounting surface of the rail R so as to be accommodated in the mounting table 4 having a cross-sectional groove shape, and the cylinder device 9 is connected to the piston rod 9a. 10 is arranged on the other side of the loading platform 3 with respect to the one side of the support column 5 and is supported by penetrating the support cylinder 11 serving also as a guide. A pressing element 12 comprising a roller 12b that is rotatably supported by the advance / retreat lever 10 is provided.

押圧子１２は、シリンダ装置の駆動によって前記支持筒１１に沿う進退杆１０の進退に伴って進退し、前進時には前記荷台３の側方に突出して、荷台３の側方において吊下されたチェーンブロック７のチェーン７ａを押圧する。   The pusher 12 advances and retreats along with the advancement and retraction of the advancement / retraction rod 10 along the support cylinder 11 by driving of the cylinder device, and protrudes to the side of the cargo bed 3 when moving forward, and is a chain suspended on the side of the cargo bed 3. The chain 7a of the block 7 is pressed.

しかして、例えば、路床が傾斜している場合、チェーンブロック７のチェーン７ａで吊り下げたレールＲは、図１の二点鎖線で示すように積卸し時に線路（既設のレール）Ｒａに近すぎて、すなわち、荷台３に近すぎてそのまま卸すことが不適当であるが、シリンダ装置９を作動させて進退杆１０を前進させて押圧子１２によってレールＲを吊り下げたチェーン７ａの中間部を押圧すると、チェーン７ａによるレールＲの吊下げ支点が荷台３乃至線路Ｒａより離開する方向に移動するので、レールＲを荷台３から離開させ卸すに適当な位置に変えられるのである。   Thus, for example, when the roadbed is inclined, the rail R suspended by the chain 7a of the chain block 7 is close to the track (existing rail) Ra at the time of unloading as shown by a two-dot chain line in FIG. Too much, ie, too close to the loading platform 3 and unsuitable for unloading, the middle part of the chain 7a in which the cylinder device 9 is operated to advance the advance / retreat lever 10 and the rail R is suspended by the presser 12 , The suspension fulcrum of the rail R by the chain 7a moves in a direction away from the loading platform 3 or the track Ra, so that the rail R can be separated from the loading platform 3 and changed to an appropriate position for wholesale.

なお、実施例のものは、進退杆１０を進退させるためにシリンダ装置９を用いたが、モータを駆動源として進退杆１０を進退させたり、或いは、ターンバックル等の螺杆を手動によって回動させて進退杆１０を進退させる等、伸縮して進退杆１０を進退操作させるものであれば、いずれの構造の伸縮操作装置でも不都合はない。   In the embodiment, the cylinder device 9 is used for advancing and retracting the advancement / retraction lever 10. However, the advancement / retraction lever 10 is advanced / retracted using a motor as a drive source, or a screw such as a turnbuckle is manually rotated. As long as the advancement / retraction lever 10 is advanced and retracted to extend and retract and the advancement / retraction operation 10 is operated, the expansion / contraction operation device of any structure is not inconvenient.
