連結部51の他端側は、前記した連結部材33と連結壁部321を超えて、荷台部81側に及んでおり、連結部51の他端には、シリンダ10により上下方向(係合ピン21の昇降方向)に移動可能とされた昇降部52が連結されている。
The connecting portion 51 is a plate-like member having a rectangular shape in plan view. As shown in FIG. 3A, the support wall portion 41 of the cover portion 40 is provided at one end side in the longitudinal direction of the connecting portion 51. It is fixed.
The other end side of the connecting portion 51 extends beyond the connecting member 33 and the connecting wall portion 321 to the loading platform portion 81 side, and the other end of the connecting portion 51 is moved vertically (engagement pin) by the cylinder 10. 21 is connected to an elevating part 52 that is movable in the elevating direction of 21).

昇降部52は、連結壁部321と荷台部81との間で、上下方向に沿わせた向きで配置されており、この昇降部52の下端には、係合ピン21を支持する支持板部53が連結されている。
支持板部53は、カバー部40の下方まで延びており、前記した底板部34の下側となる位置に係合ピン21が固定されている。係合ピン21は、底板部34の下面に固定された筒状の支持部材25を貫通した軸状部材であり、係合ピン21は、シリンダ10の駆動による昇降部52の上下方向の移動に連動して、支持板部53と一緒に昇降移動することで、底板部34の挿通孔34aから出没するようになっている。
The elevating part 52 is disposed between the connecting wall part 321 and the loading platform part 81 in the direction along the vertical direction, and a support plate part that supports the engagement pin 21 is provided at the lower end of the elevating part 52. 53 are connected.
The support plate portion 53 extends below the cover portion 40, and the engagement pin 21 is fixed at a position below the bottom plate portion 34 described above. The engagement pin 21 is a shaft-like member that penetrates a cylindrical support member 25 fixed to the lower surface of the bottom plate portion 34, and the engagement pin 21 is used for the vertical movement of the elevating part 52 by driving the cylinder 10. By interlocking and moving up and down together with the support plate portion 53, the base plate portion 34 comes and goes out of the insertion hole 34 a.

ここで、シリンダ10の駆動による昇降部52の上下方向の移動に連動して、連結部51もまた昇降移動するため、連結装置2では、底板部34の挿通孔34aからの係合ピン21の出没と、カバー部40(揺動壁45)の昇降とが連動するようになっている。   Here, since the connecting portion 51 also moves up and down in conjunction with the vertical movement of the elevating portion 52 by driving the cylinder 10, in the connecting device 2, the engagement pin 21 from the insertion hole 34 a of the bottom plate portion 34 is moved. The appearance and the elevation of the cover 40 (the swing wall 45) are interlocked.

実施の形態では、係合ピン21を連結アーム91の係合孔92に係合させて、牽引車両8と台車90とを連結した連結位置(図3の(c)参照)と、係合ピン21を係合孔92から下方に離脱させた連結解除位置(図3の(b)参照)との間を、係合ピン21が昇降するようになっており、図示しない制御装置からの駆動信号によりシリンダ10を駆動して、係合ピン21を昇降させることで、牽引車両8と台車90との連結/連結解除が行われるようになっている。   In the embodiment, the engaging pin 21 is engaged with the engaging hole 92 of the connecting arm 91 to connect the tow vehicle 8 and the carriage 90 (see FIG. 3C), and the engaging pin. The engagement pin 21 is moved up and down between a connection release position (see FIG. 3B) where the 21 is released downward from the engagement hole 92, and a drive signal from a control device (not shown) Thus, the cylinder 10 is driven and the engagement pin 21 is moved up and down to connect / disconnect the tow vehicle 8 and the carriage 90.

ここで、実施の形態では、係合ピン21の連結解除位置の下側に、連結準備位置(図3の(a)参照)が設定されている。
係合ピン21が連結準備位置に配置されると、前記したカバー部40の揺動壁45の下縁451側が、底板部34とストッパ27の基部271との間の隙間S(図2の(b)参照)に収容されて、揺動壁45の係合ピン21から離れる方向への移動がストッパ27の基部271により規制されるようになっている。
この状態において揺動壁45は、係合ピン21側の底板部34と干渉しないようにされており、係合ピン21が連結準備位置に配置されると、揺動壁45の係合ピン21側への変位を許容しつつ、揺動壁45の係合ピン21から離れる方向への移動が規制されるようになっている。
Here, in the embodiment, a connection preparation position (see FIG. 3A) is set below the connection release position of the engagement pin 21.
When the engagement pin 21 is disposed at the connection preparation position, the lower edge 451 side of the swing wall 45 of the cover portion 40 is a gap S between the bottom plate portion 34 and the base portion 271 of the stopper 27 ((( b), the movement of the oscillating wall 45 in the direction away from the engaging pin 21 is regulated by the base portion 271 of the stopper 27.
In this state, the swing wall 45 is configured not to interfere with the bottom plate portion 34 on the engagement pin 21 side. The movement of the oscillating wall 45 in the direction away from the engagement pin 21 is restricted while allowing the displacement to the side.

実施の形態では、係合ピン21が、連結準備位置の上方の連結解除位置(図3の(b)参照)に配置されると、揺動壁45の下縁451が、ストッパ27の基部271よりも上方に配置されて、揺動壁45の下縁451の係合ピン21から離れる方向への移動が許容されるようになっている。   In the embodiment, when the engagement pin 21 is disposed at the connection release position (see FIG. 3B) above the connection preparation position, the lower edge 451 of the swing wall 45 is the base 271 of the stopper 27. The lower edge 451 of the rocking wall 45 is allowed to move away from the engagement pin 21.

さらに、係合ピン21が連結位置(図3の(c)参照)に配置されると、揺動壁45の下縁451が、支持板部35よりも上方に配置さて、支持板部35と底板部34との間に挿入された連結アーム91が、係合ピン21を支点として軸線X周りに回動しても、揺動壁45、45と干渉しないようにされている。   Further, when the engagement pin 21 is disposed at the coupling position (see FIG. 3C), the lower edge 451 of the swing wall 45 is disposed above the support plate 35, and the support plate 35 is Even if the connecting arm 91 inserted between the bottom plate portion 34 and the engaging pin 21 rotates around the axis X, it does not interfere with the rocking walls 45 and 45.

以下、かかる構成の連結装置2を備える牽引車両8と台車90との連結を説明する。
図4は、連結装置2による連結/連結解除を説明する図であって、台車列9Aを牽引している牽引車両8が、台車列9Aとの連結を解除したのち、台車列9Bに新たに連結されるまでの間の牽引車両8の移動軌跡を模式的に示した図である。
図5および図6は、連結装置2による連結/連結解除を説明する図であって、連結装置2の係合ピン21と、台車90の連結アーム91の係合孔92との係合、離脱を説明する図である。
Hereinafter, the connection between the tow vehicle 8 including the connecting device 2 configured as described above and the carriage 90 will be described.
FIG. 4 is a diagram for explaining the connection / disconnection by the connecting device 2, and after the tow vehicle 8 towing the bogie train 9 </ b> A decouples from the bogie train 9 </ b> A, it is newly added to the cart train 9 </ b> B. It is the figure which showed typically the movement locus | trajectory of the tow vehicle 8 until it connects.
5 and 6 are diagrams for explaining the connection / disconnection by the connection device 2, and the engagement and disengagement between the engagement pin 21 of the connection device 2 and the engagement hole 92 of the connection arm 91 of the carriage 90. FIG.

牽引車両8が台車列9Aを牽引している状態では、連結装置2の係合ピン21と、揺動壁45、45は、連結位置に配置されている(図5の(a)、(b)参照)。
この状態において、カバー部40の揺動壁45、45は、支持板部35よりも上方に下縁451、451を位置させており、連結アーム91が軸線X周りに回動しても、連結アーム91と揺動壁45、45とが互いに干渉しないようになっている。
そのため、牽引車両8が旋回移動する際に、連結アーム91が揺動壁45、45と干渉して、牽引車両8の旋回移動が阻害されないようになっている。
In a state where the tow vehicle 8 is towing the bogie train 9A, the engaging pin 21 and the rocking walls 45, 45 of the coupling device 2 are disposed at the coupling position (FIGS. 5A and 5B). )reference).
In this state, the rocking walls 45 and 45 of the cover part 40 have the lower edges 451 and 451 positioned above the support plate part 35, so that even if the connection arm 91 rotates about the axis X, the connection is possible. The arm 91 and the oscillating walls 45 and 45 do not interfere with each other.
Therefore, when the tow vehicle 8 turns, the connecting arm 91 interferes with the rocking walls 45 and 45 so that the turning movement of the tow vehicle 8 is not hindered.

台車列9Aを牽引している牽引車両8が、台車列9Aの切離し位置(図4:位置A)に到達すると、牽引車両8は自走を止めて(停車して)台車列9Aの牽引を終了する。
そして、シリンダ10を駆動して、係合ピン21を連結位置(図5の(a)、(b)参照)から、この連結位置よりも下方の連結解除位置(図5の(c)、(d)参照)に向けて移動させる。この係合ピン21の下方への移動に伴って、カバー部40の揺動壁45、45もまた、底板部34側の下方に変位することになる。
When the towing vehicle 8 that is towing the bogie train 9A reaches the separation position (FIG. 4: position A) of the bogie train 9A, the towing vehicle 8 stops (stops) and stops towing the bogie train 9A. finish.
Then, the cylinder 10 is driven to move the engagement pin 21 from the connection position (see FIGS. 5A and 5B) to the connection release position below the connection position (FIGS. 5C and 5C). d) move toward (see). As the engaging pin 21 moves downward, the rocking walls 45 and 45 of the cover portion 40 are also displaced downward on the bottom plate portion 34 side.

係合ピン21が連結解除位置(図5の(c)、(d)参照)まで移動すると、係合ピン21は、上端21aを、連結アーム91の係合孔92よりも下方に配置させた状態となり、係合ピン21と係合孔92とが非係合状態になる。
さらに、係合ピン21の下方への移動に連動して底板部34側の下方に変位した揺動壁45、45は、下縁451、451を、ストッパ27、27の基部271、271よりも上方に配置させた状態になる。
この状態では、揺動壁45、45は、係合ピン21から離れる方向に変位しても、ストッパ27、27の基部271、271に干渉しない高さ位置に配置されているので、揺動壁45、45は、係合ピン21に近づく方向の変位と、係合ピン21から離れる方向への移動とが許容された状態となっている。
When the engagement pin 21 moves to the connection release position (see FIGS. 5C and 5D), the engagement pin 21 has the upper end 21 a disposed below the engagement hole 92 of the connection arm 91. The engagement pin 21 and the engagement hole 92 are disengaged.
Further, the rocking walls 45, 45 displaced downward on the bottom plate portion 34 side in conjunction with the downward movement of the engagement pin 21 make the lower edges 451, 451 more than the base portions 271, 271 of the stoppers 27, 27. It will be in the state arrange | positioned upwards.
In this state, the oscillating walls 45, 45 are arranged at a height position that does not interfere with the bases 271, 271 of the stoppers 27, 27 even if displaced in a direction away from the engagement pin 21. 45 and 45 are in a state where displacement in a direction approaching the engagement pin 21 and movement in a direction away from the engagement pin 21 are allowed.

よって、この状態で牽引車両8を旋回移動(図4における矢印A)させると、連結アーム91の係合孔92が設けられた一端91a側と係合ピン21とが、係合ピン21の径方向(水平方向)で相対的に移動して、連結アーム91の一端91a側は一方の揺動壁45に接触することになる。
そうすると、連結アーム91の一端91a側が接触した揺動壁45は、係合ピン21から離れる方向への移動が許容されているので、一端91aにより押されて、揺動軸Y1周りに揺動する。
これにより、連結アーム91の一端91a側が、揺動壁45、45の間から外側に移動することになる(図4:位置A、仮想線参照)。
Therefore, when the towing vehicle 8 is turned in this state (arrow A in FIG. 4), the one end 91 a side where the engagement hole 92 of the connection arm 91 is provided and the engagement pin 21 are connected to the diameter of the engagement pin 21. By moving relatively in the direction (horizontal direction), the one end 91 a side of the connecting arm 91 comes into contact with one swing wall 45.
As a result, the swing wall 45 that is in contact with the one end 91a side of the connecting arm 91 is allowed to move away from the engagement pin 21, so that the swing wall 45 is pushed by the one end 91a and swings around the swing axis Y1. .
Thereby, the one end 91a side of the connection arm 91 moves outside between the rocking walls 45 and 45 (see FIG. 4: position A, virtual line).

そして、牽引車両8が旋回を続けると、連結アーム91がストッパ27のガイドアーム272の上面を摺動しながら移動して、最終的にストッパ27から連結アーム91が外れて、牽引車両8が台車列9Aから切り離されることになる。   When the towing vehicle 8 continues to turn, the connecting arm 91 moves while sliding on the upper surface of the guide arm 272 of the stopper 27, and finally the connecting arm 91 is detached from the stopper 27, so that the towing vehicle 8 is a carriage. It will be disconnected from the column 9A.

そして、白線WLに沿って牽引車両8を台車列9B側に移動させる。実施の形態では、牽引車両8の連結装置2側を大きく旋回させながら、牽引車両8の進行方向を台車列9Bの延長線上に位置させるように、白線WLが設定されている(図4参照)。   Then, the tow vehicle 8 is moved to the carriage row 9B side along the white line WL. In the embodiment, the white line WL is set so that the traveling direction of the tow vehicle 8 is positioned on the extended line of the carriage train 9B while largely turning the connecting device 2 side of the tow vehicle 8 (see FIG. 4). .

牽引車両8が台車列9Bとの切替準備位置(図4:位置B)に到達すると、シリンダ10を駆動して、係合ピン21を連結解除位置(図5の(c)、(d)参照)から、この連結解除位置の下方の連結準備位置(図6の(a)、(b)参照)まで移動させる。
この係合ピン21の下方への移動に伴って、カバー部40の揺動壁45、45もまた、底板部34側の下方に変位することになる。
When the tow vehicle 8 reaches the switch preparation position (FIG. 4: position B) with the bogie train 9B, the cylinder 10 is driven to engage the engagement pin 21 (see FIGS. 5C and 5D). ) To a connection preparation position below the connection release position (see FIGS. 6A and 6B).
As the engaging pin 21 moves downward, the rocking walls 45 and 45 of the cover portion 40 are also displaced downward on the bottom plate portion 34 side.

そうすると、係合ピン21の下方への移動に連動して底板部34側の下方に変位した揺動壁45、45は、下縁451、451を、ストッパ27、27の基部271、271と、底板部34、34の間の隙間S内に配置させた状態になる。
この状態では、揺動壁45、45は、係合ピン21から離れる方向への変位が、ストッパ27、27の基部271、271に干渉して規制されるので、揺動壁45、45は、係合ピン21に近づく方向の変位のみが許容され、係合ピン21から離れる方向への移動が規制されている。
Then, the rocking walls 45, 45 displaced downward on the bottom plate part 34 side in conjunction with the downward movement of the engagement pin 21, the lower edges 451, 451, the bases 271, 271 of the stoppers 27, 27, It will be in the state arrange | positioned in the clearance gap S between the baseplate parts 34 and 34. FIG.
In this state, the rocking walls 45, 45 are restricted from displacement in the direction away from the engagement pin 21 by interfering with the bases 271, 271 of the stoppers 27, 27. Only displacement in a direction approaching the engagement pin 21 is allowed, and movement in a direction away from the engagement pin 21 is restricted.

よって、この状態で牽引車両8を旋回移動(図4における矢印B)させると、連結アーム91の係合孔92が設けられた一端91a側と係合ピン21とが、係合ピン21の径方向(水平方向)で相対的に移動して、係合ピン21と連結アーム91とが互いに近づくことになる。   Therefore, when the towing vehicle 8 is turned in this state (arrow B in FIG. 4), the one end 91 a side where the engagement hole 92 of the connection arm 91 is provided and the engagement pin 21 are connected to the diameter of the engagement pin 21. By relatively moving in the direction (horizontal direction), the engaging pin 21 and the connecting arm 91 come closer to each other.

そうすると、ストッパ27のガイドアーム272の折返し部272a側が、基部271よりも下側に位置しているので、連結アーム91の一端91a側が、ガイドアーム272の折返し部272a側から、ガイドアーム272に乗り上げることになる(図2の(b)、仮想線参照)。   Then, since the folded portion 272a side of the guide arm 272 of the stopper 27 is positioned below the base portion 271, the one end 91a side of the connecting arm 91 rides on the guide arm 272 from the folded portion 272a side of the guide arm 272. (Refer to the virtual line in FIG. 2B).

そして、牽引車両8が旋回を続けると、連結アーム91がガイドアーム272の上面を摺動しながら基部271に近づくことになる。ここで、ガイドアーム272の基部271側は、底板部34と同じ高さ位置に配置されているので、連結アーム91の一端91a側の高さ位置が、基部271に近づくにつれて、係合ピン21との係合に適した高さ位置まで誘導されるようになっている。   When the towing vehicle 8 continues to turn, the connecting arm 91 approaches the base 271 while sliding on the upper surface of the guide arm 272. Here, since the base 271 side of the guide arm 272 is disposed at the same height position as the bottom plate portion 34, the engagement pin 21 becomes closer as the height position on the one end 91 a side of the connecting arm 91 approaches the base 271. It is guided to a height position suitable for engagement with.

そして、図6の(a)、(b)に示すように、連結アーム91の一端91a側が、揺動壁45の係合ピン21とは反対側の面に当接すると、揺動壁45は、係合ピン21に近づく方向の変位が許容されているので、連結アーム91の一端91a側により押されて、揺動軸Y1周りに揺動する。これにより、連結アーム91の一端91a側は、揺動壁45を押し上げながら、揺動壁45、45の間に進入されることになる。   Then, as shown in FIGS. 6A and 6B, when the one end 91 a side of the connecting arm 91 comes into contact with the surface of the swing wall 45 opposite to the engagement pin 21, the swing wall 45 is Since the displacement in the direction approaching the engagement pin 21 is allowed, it is pushed by the one end 91a side of the connecting arm 91 and swings around the swing axis Y1. As a result, the one end 91 a side of the connecting arm 91 enters between the rocking walls 45, 45 while pushing up the rocking wall 45.

そして、最終的に連結アーム91の一端91a側は、反対側の揺動壁45の係合ピン21側の面に当接して、揺動壁45を係合ピン21から離れる方向に変位させようとするが、揺動壁45の係合ピン21から離れる方向への変位が、ストッパ27の基部271により規制されているので、連結アーム91の一端91a側は、揺動壁45、45の間に保持された状態となる(図6の(c)、(d)参照)。   Finally, the one end 91 a side of the connecting arm 91 abuts on the surface of the opposite swing wall 45 on the side of the engagement pin 21, and the swing wall 45 is displaced away from the engagement pin 21. However, since the displacement of the swing wall 45 in the direction away from the engaging pin 21 is restricted by the base portion 271 of the stopper 27, the one end 91 a side of the connecting arm 91 is between the swing walls 45, 45. (See (c) and (d) of FIG. 6).

これにより、連結アーム91の一端91a側は、係合孔92を、係合ピン93との係合位置に保持させた状態となる。
よって、この状態から係合ピン21を係合位置まで上昇させて係合孔92に係合させると(図6の(c)、矢印参照)、台車列9Bと牽引車両8とが、連結装置2により連結された状態となる(図4:位置B、仮想線参照)。
As a result, the one end 91 a side of the connecting arm 91 is in a state where the engagement hole 92 is held at the engagement position with the engagement pin 93.
Therefore, when the engagement pin 21 is raised to the engagement position from this state and engaged with the engagement hole 92 (see the arrow in FIG. 6C), the carriage train 9B and the towing vehicle 8 are connected to each other by the connecting device. 2 (see FIG. 4: position B, virtual line).

以上の通り、実施の形態では
(1)自走可能な牽引車両8に設けられており、当該牽引車両8に牽引される台車90(被牽引車両)備える連結アーム91の係合孔92に係合ピン21を係脱させて、牽引車両8と台車90との連結/連結解除を行う連結装置2であって、

係合ピン21の昇降方向(軸線X)から見て、係合ピン21の両側に設けられていると共に、係合ピン21の昇降に連動して、昇降機構(シリンダ10、連結部51)により、昇降する一対の揺動壁45、45(側壁)と、を有し、
一対の揺動壁45,45の各々を、係合ピン21の昇降方向(軸線X)に直交する揺動軸Y1、Y2周りに揺動可能に設けて、揺動壁45、45の下縁451、451側を、係合ピン21の径方向に変位可能にすると共に、連結アーム91の係合孔92が設けられた一端91a側を、係合ピン21の径方向に位置する揺動壁45、45側から、揺動壁45、45の間に進入可能とし、
係合ピン21の昇降方向(軸線X方向)から見て、揺動壁45、45の係合ピン21とは反対側に、揺動壁45、45の下縁451、451側の係合ピン21から離れる方向への変位を基部271、271で規制する一対のストッパ27、27(規制部材)を設けて、揺動壁45、45の間に進入した連結アーム91の一端91a側が、係合孔92を係合ピン21との係合位置に配置されるようにした。

The engagement pin 21 is provided on both sides of the engagement pin 21 as viewed from the ascending / descending direction (axis X), and is interlocked with the ascent / descent of the engagement pin 21 by the elevating mechanism (cylinder 10, connecting portion 51). A pair of swing walls 45 and 45 (side walls) that move up and down,
Each of the pair of swing walls 45, 45 is provided so as to be swingable around swing axes Y 1, Y 2 orthogonal to the ascending / descending direction (axis X) of the engagement pin 21, and the lower edge of the swing walls 45, 45 The 451 and 451 sides are displaceable in the radial direction of the engagement pin 21, and the one end 91 a provided with the engagement hole 92 of the connecting arm 91 is positioned on the rocking wall positioned in the radial direction of the engagement pin 21. From 45, 45 side, it is possible to enter between the rocking walls 45, 45,
When viewed from the ascending / descending direction of the engaging pin 21 (axis X direction), the engaging pin on the lower edge 451, 451 side of the rocking wall 45, 45 on the opposite side of the rocking wall 45, 45 from the engaging pin 21. 21 is provided with a pair of stoppers 27 and 27 (regulating members) for restricting displacement in the direction away from the bases 271 and 271, and the one end 91 a side of the connecting arm 91 entering between the swing walls 45 and 45 is engaged. The hole 92 is arranged at an engagement position with the engagement pin 21.

このように構成すると、連結アーム91の一端91a側と係合ピン21とが、係合ピン21の径方向で互いに近づく方向に相対移動するように自走可能な牽引車両8を移動させると、連結アーム91の係合孔92が設けられた一端91a側が、揺動可能な一対の揺動壁45、45のうちの一方の揺動壁45側から一対の揺動壁45、45の間に進入する。
そうすると、一対の揺動壁45、45は、ストッパ27、27の基部271、271により係合ピン21から離れる方向への変位が規制されているので、一対の揺動壁45、45の間に進入した連結アームの一端側は、一対の揺動壁45、45の間の係合ピン21との係合位置に配置される。
この状態で昇降機構により係合ピン21を上昇させることで、連結アーム91の係合孔92に係合ピン21を係合させて牽引車両8と台車90とを連結装置2により連結することができる。
これにより、牽引車両8への台車90の連結を、作業者の手を介さずに行うことができるので、台車90や、複数台の台車90を直列に連結した台車列9の切替作業時の作業負担を低減させることができる。
If comprised in this way, if the one end 91a side of the connection arm 91 and the engagement pin 21 will move the tow vehicle 8 which can be self-propelled so that it may move relatively in the direction which mutually approaches in the radial direction of the engagement pin 21, The one end 91 a side where the engagement hole 92 of the connecting arm 91 is provided is between one swing wall 45 side of the pair of swing walls 45, 45 that can swing between the pair of swing walls 45, 45. enter in.
Then, since the displacement of the pair of swing walls 45, 45 in the direction away from the engagement pin 21 is restricted by the bases 271, 271 of the stoppers 27, 27, the pair of swing walls 45, 45 is interposed between the pair of swing walls 45, 45. One end side of the connecting arm that has entered is disposed at an engagement position with the engagement pin 21 between the pair of swing walls 45, 45.
In this state, the engaging pin 21 is raised by the elevating mechanism so that the engaging pin 21 is engaged with the engaging hole 92 of the connecting arm 91 and the traction vehicle 8 and the carriage 90 are connected by the connecting device 2. it can.
As a result, the carriage 90 can be connected to the towing vehicle 8 without an operator's hand, so that the carriage 90 or the carriage train 9 in which a plurality of carriages 90 are connected in series can be switched. The work burden can be reduced.

(2)昇降機構は、係合ピン21を、当該係合ピン21を係合孔92に係合させた連結位置と、係合ピン21を連結位置よりも下側の係合孔92から離脱させた連結解除位置と、
係合ピン21を、連結解除位置よりも下側の連結準備位置とに配置されるように構成されており、
一対の揺動壁45、45は、係合ピン21が連結準備位置に配置されているときに、ストッパ27、27の基部271、271に干渉して係合ピン21から離れる方向への変位が規制される高さ位置に配置されると共に、係合ピン21が連結位置または連結解除位置に配置されているときに、ストッパ27、27の基部271、271に干渉しない高さ位置に配置されるように、一対の揺動壁45、45の下縁451、451と、ストッパ27、27の基部271、271のうち少なくとも一方の昇降方向(軸線X方向)の高さが設定されている構成とした。
(2) The elevating mechanism disengages the engagement pin 21 from the connection position where the engagement pin 21 is engaged with the engagement hole 92 and the engagement pin 21 from the engagement hole 92 below the connection position. The released connection position,
The engagement pin 21 is configured to be disposed at a connection preparation position below the connection release position,
When the engagement pin 21 is disposed at the connection preparation position, the pair of rocking walls 45 and 45 are displaced in a direction away from the engagement pin 21 by interfering with the base portions 271 and 271 of the stoppers 27 and 27. It is disposed at a regulated height position, and is disposed at a height position that does not interfere with the base portions 271 and 271 of the stoppers 27 and 27 when the engagement pin 21 is disposed at the connection position or the connection release position. As described above, the height of at least one of the lower edges 451 and 451 of the pair of swing walls 45 and 45 and the bases 271 and 271 of the stoppers 27 and 27 is set in the ascending / descending direction (axis X direction). did.

このように構成すると、係合ピン21を係合孔92から離脱させた連結解除位置に配置すると、一対の揺動壁45、45の係合ピン21から離れる方向への変位が、ストッパ27、27の基部271、271に規制されない状態となる。
この状態で、連結アーム91の一端91a側と係合ピン21とが、係合ピン21の径方向(水平方向)で互いに離れる方向に相対移動するように自走可能な牽引車両8を移動させると、連結アーム91の係合孔92が設けられた一端91a側が、揺動可能な一対の揺動壁45、45のうちの一方の揺動壁45から一対の揺動壁45、45の間から外部に移動して、台車90の連結アーム91が連結装置2から離脱した状態になる。
一方、係合ピン21を、連結解除位置の下側の連結準備位置に配置すると、一対の揺動壁45、45は、係合ピン21に近づく方向への変位が許容されつつ、係合ピン21から離れる方向への変位がストッパ27、27の基部271、271により規制された状態となる。
この状態で、連結アーム91の一端91a側と係合ピン21とが、係合ピン21の径方向(水平方向)で互いに近づく方向に相対移動するように自走可能な牽引車両8を移動させると、連結アーム91の係合孔92が設けられた一端91a側が、揺動可能な一対の揺動壁45、45のうちの一方の揺動壁45側から一対の揺動壁45、45の間に進入して、一対の揺動壁45、45の間の係合ピン21との係合位置に配置される。
そして、昇降機構により係合ピン21を上昇させることで、連結アーム91の係合孔92に係合ピン21を係合させて牽引車両8と台車90とを連結装置2により連結することができる。
これにより、作業者の手を介さずに、牽引車両8と台車90との連結と連結解除を行うことができるので、台車90や、複数台の台車90を直列に連結した台車列9の切替作業時の作業負担をいっそう低減させることができる。
With this configuration, when the engagement pin 21 is disposed at the connection release position separated from the engagement hole 92, the displacement of the pair of swing walls 45, 45 in the direction away from the engagement pin 21 is caused by the stopper 27, It will be in the state which is not controlled by 27 bases 271 and 271.
In this state, the tow vehicle 8 capable of self-propelling is moved so that the one end 91a side of the connecting arm 91 and the engaging pin 21 move relative to each other in a direction away from each other in the radial direction (horizontal direction) of the engaging pin 21. The one end 91a side where the engagement hole 92 of the connecting arm 91 is provided is between one swing wall 45 of the pair of swing walls 45 and 45 that can swing between the pair of swing walls 45 and 45. The connecting arm 91 of the carriage 90 is detached from the connecting device 2 from the connecting device 2 to the outside.
On the other hand, when the engagement pin 21 is arranged at the lower connection preparation position of the connection release position, the pair of rocking walls 45 and 45 are allowed to move in a direction approaching the engagement pin 21 while the engagement pin 21 is disengaged. The displacement in the direction away from 21 is regulated by the bases 271 and 271 of the stoppers 27 and 27.
In this state, the tow vehicle 8 capable of self-propelling is moved so that the one end 91a side of the connecting arm 91 and the engaging pin 21 move relative to each other in the radial direction (horizontal direction) of the engaging pin 21. And the one end 91a side where the engagement hole 92 of the connecting arm 91 is provided is a position of the pair of swing walls 45, 45 from one swing wall 45 side of the pair of swing walls 45, 45 that can swing. It enters in between and is disposed at an engagement position with the engagement pin 21 between the pair of swing walls 45, 45.
Then, by raising the engagement pin 21 by the elevating mechanism, the engagement pin 21 can be engaged with the engagement hole 92 of the connection arm 91 and the traction vehicle 8 and the carriage 90 can be connected by the connection device 2. .
Thereby, since the connection and disconnection of the tow vehicle 8 and the cart 90 can be performed without an operator's hand, the cart 90 or the cart train 9 in which a plurality of carts 90 are connected in series can be switched. The work burden during the work can be further reduced.

特に、係合ピン21を係合孔92に係合させた連結位置に配置されているときに、
一対の揺動壁45、45の下縁451、451が、連結アーム91の一端91aと干渉しない高さ位置に配置されるように設定されている構成とした。
これにより、牽引車両8が連結装置2を介して連結された台車90(台車列9)を牽引している際に、牽引車両8の旋回移動により連結アーム91が軸線X周りに回動しても、連結アーム91と揺動壁45、45とが互いに干渉しない。
そのため、牽引車両8が旋回移動する際に、連結アーム91が揺動壁45、45と干渉して、牽引車両8の旋回移動が阻害されることがない。
In particular, when the engagement pin 21 is disposed at the coupling position where the engagement pin 21 is engaged with the engagement hole 92,
The lower edges 451 and 451 of the pair of swing walls 45 and 45 are configured to be arranged at a height position that does not interfere with the one end 91a of the connecting arm 91.
Thereby, when the towing vehicle 8 is towing the carriage 90 (the carriage row 9) connected via the connecting device 2, the connecting arm 91 is rotated around the axis X by the turning movement of the towing vehicle 8. However, the connecting arm 91 and the rocking walls 45 and 45 do not interfere with each other.
Therefore, when the towing vehicle 8 turns, the connecting arm 91 does not interfere with the rocking walls 45 and 45 and the turning movement of the towing vehicle 8 is not hindered.

(3)ストッパ27、27(規制部材)は、係合ピン21から離れる方向に基部271、271から延びるガイドアーム272、272(ガイド部)を有しており、
ガイドアーム272、272は、連結アーム91の一端91a側と係合ピン21とを、係合ピン21の径方向(水平方向)で互いに近づく方向に相対移動させて、連結アーム91の一端91a側を一対の揺動壁45、45の間に進入させる際に、連結アーム91の一端91a側の下面を摺動して、連結アーム91の一端91a側の高さを一対の揺動壁45、45の間に進入可能な高さに調整して、一対の揺動壁45、45の間への進入をガイドする構成とした。
(3) The stoppers 27, 27 (regulating members) have guide arms 272, 272 (guide portions) extending from the base portions 271, 271 in a direction away from the engagement pin 21.
The guide arms 272 and 272 move the one end 91a side of the connecting arm 91 and the engaging pin 21 relative to each other in a direction approaching each other in the radial direction (horizontal direction) of the engaging pin 21, and thereby the one end 91a side of the connecting arm 91. Is moved between the pair of oscillating walls 45, 45, the lower surface on the one end 91 a side of the connecting arm 91 is slid so that the height on the one end 91 a side of the connecting arm 91 is set to the pair of oscillating walls 45, 45. The height between the pair of swing walls 45 and 45 is adjusted by adjusting the height to allow the entry between the pair of swing walls 45 and 45.

このように構成すると、連結アーム91の一端91a側の一対の揺動壁45、45の間への進入がスムーズになるので、牽引車両8と台車90との連結をより短時間、かつスムーズに行うことができる。
特に、連結アーム91の一端91a側の高さと、一対の揺動壁45、45の高さとが異なる場合には、連結アーム91の一端91a側を一対の揺動壁45、45の間に進入させることができなくなるが、ガイドアーム272、272を設けることで、かかる事態の発生を好適に防止できる。
If comprised in this way, since the approach between a pair of rocking | fluctuation walls 45 and 45 by the side of the one end 91a of the connection arm 91 will become smooth, connection with the tow vehicle 8 and the trolley | bogie 90 will be smooth for a short time. It can be carried out.
In particular, when the height of the connecting arm 91 on the one end 91a side is different from the height of the pair of swing walls 45, 45, the end 91a side of the connecting arm 91 enters between the pair of swing walls 45, 45. However, the provision of the guide arms 272 and 272 can suitably prevent such a situation from occurring.

(4)ガイドアーム272、272の形状は、基部271、271からの延出方向における先端側(折返し部272a側)のほうが、係合ピン21側の基部271、271よりも低い高さに位置するように、延出方向における途中位置から下方に向けて屈曲している構成とした。 (4) The shape of the guide arms 272 and 272 is such that the distal end side (folded portion 272a side) in the extending direction from the base portions 271 and 271 is positioned lower than the base portions 271 and 271 on the engagement pin 21 side. Thus, it was set as the structure bent toward the downward direction from the middle position in the extending direction.

このように構成すると、連結アーム91の一端91a側が、一対の揺動壁45、45よりも低い位置にある場合であっても、連結アーム91の一端91a側を一対の揺動壁45、45の間に進入させることができ、牽引車両8と台車90との連結をより短時間、かつスムーズに行うことができる。   If comprised in this way, even if it is a case where the end 91a side of the connection arm 91 exists in a position lower than a pair of rocking | fluctuation wall 45,45, the end 91a side of the connection arm 91 will be a pair of rocking | fluctuation wall 45,45. The tow vehicle 8 and the carriage 90 can be connected in a shorter time and smoothly.

前記した実施の形態では、係合ピン21の昇降方向(軸線X方向)から見て、カバー部40が、係合ピン21の両側に配置される一対の揺動壁45、45を備えている場合を例示したが、図7に示すように、係合ピン21の両側に位置する一対の壁部のうちの一方のみを揺動壁45としたカバー部40Aを採用しても良い。   In the above-described embodiment, the cover portion 40 includes a pair of swing walls 45 and 45 disposed on both sides of the engagement pin 21 when viewed from the ascending / descending direction (axis X direction) of the engagement pin 21. Although the case is illustrated, as shown in FIG. 7, a cover portion 40 </ b> A in which only one of the pair of wall portions located on both sides of the engagement pin 21 is the swing wall 45 may be employed.

図7は、変形例に係るカバー部40Aを備える連結装置2での牽引車両8側の係合ピン21と台車90側の連結アーム91との連結を説明する断面図であり、(a)は、係合ピン21が、連結準備位置に配置された状態を示す図であり、(b)は、係合ピン21が、連結解除位置に配置された状態を示す図であり、(c)は、係合ピン21が、連結位置に配置された状態を示す図である。   FIG. 7 is a cross-sectional view for explaining the connection between the engaging pin 21 on the tow vehicle 8 side and the connecting arm 91 on the carriage 90 side in the connecting device 2 including the cover portion 40A according to the modification. FIG. 4 is a diagram showing a state where the engagement pin 21 is arranged at the connection preparation position, FIG. 5B is a diagram showing a state where the engagement pin 21 is arranged at the connection release position, and FIG. The engagement pin 21 is a figure which shows the state arrange | positioned in the connection position.

カバー部40Aは、底板部34の上方で底板部34に対して並行に配置された板状の支持壁部41と、支持壁部41の幅方向の両側から底板部34側の下方に延びる一対の側壁部42、43を有している。   40 A of cover parts are the plate-shaped support wall part 41 arrange | positioned in parallel with the baseplate part 34 above the baseplate part 34, and a pair extended from the both sides of the width direction of the support wall part 41 below the baseplate part 34 side. Side wall portions 42 and 43.

側壁部42、43は、軸線Xを挟んで対称となる位置で、互いに平行に設けられており、この側壁部42、43のうちの一方の側壁部43の下部には、ヒンジ46を介して揺動壁45が支持されている。
揺動壁45は、軸線Xに直交する水平軸(揺動軸Y2)周りに揺動可能となっており、揺動壁45の下縁451側は、軸線Xの径方向(係合ピン21に近づく方向と、係合ピン21から離れる方向)に変位可能となっている。
さらに、変形例では、揺動壁45の下縁451と、側縁部42の下縁421とが同じ高さ位置に配置されるように、側縁部42、43と揺動壁45の昇降方向(軸線X方向)の長さが設定されている。
The side wall portions 42 and 43 are provided in parallel with each other at positions symmetrical with respect to the axis X, and a lower portion of one side wall portion 43 of the side wall portions 42 and 43 is interposed via a hinge 46. A rocking wall 45 is supported.
The swing wall 45 can swing around a horizontal axis (swing axis Y2) orthogonal to the axis X, and the lower edge 451 side of the swing wall 45 is in the radial direction of the axis X (engagement pin 21). In the direction of approaching and away from the engagement pin 21).
Furthermore, in the modified example, the side edges 42 and 43 and the swing wall 45 are moved up and down so that the lower edge 451 of the swing wall 45 and the lower edge 421 of the side edge 42 are arranged at the same height position. The length of the direction (axis X direction) is set.

連結装置2では、変形例にかかるカバー部40Aを備える場合も同様に、係合ピン21を連結アーム91の係合孔92に係合させて、牽引車両8と台車90とを連結した連結位置(図7の(c)参照)と、係合ピン21を係合孔92から下方に離脱させた連結解除位置(図7の(b)参照)との間を、係合ピン21が昇降するようになっており、図示しない制御装置からの駆動信号によりシリンダ10を駆動して、係合ピン21を昇降させることで、牽引車両8と台車90との連結/連結解除が行われるようになっている。   Similarly, in the connection device 2, when the cover portion 40 </ b> A according to the modification is provided, the connection position where the traction vehicle 8 and the carriage 90 are connected by engaging the engagement pin 21 with the engagement hole 92 of the connection arm 91. (See (c) of FIG. 7) and the engagement pin 21 moves up and down between the connection release position (see (b) of FIG. 7) where the engagement pin 21 is released downward from the engagement hole 92. The cylinder 10 is driven by a drive signal from a control device (not shown), and the engagement pin 21 is moved up and down, so that the traction vehicle 8 and the carriage 90 are connected / disconnected. ing.

さらに、係合ピン21の連結解除位置の下側に、連結準備位置(図7の(a)参照)が設定されており、係合ピン21が連結準備位置に配置されると、カバー部40の揺動壁45の下縁451側が、底板部34とストッパ27の基部271との間の隙間Sに収容されて、揺動壁45の係合ピン21から離れる方向への移動がストッパ27の基部271により規制されるようになっている。
この状態において揺動壁45は、係合ピン21側の底板部34と干渉しないようにされており、係合ピン21が連結準備位置に配置されると、揺動壁45の係合ピン21側への変位を許容しつつ、揺動壁45の係合ピン21から離れる方向への移動が規制されるようになっている。
Furthermore, a connection preparation position (see FIG. 7A) is set below the connection release position of the engagement pin 21, and when the engagement pin 21 is arranged at the connection preparation position, the cover portion 40 is provided. The lower edge 451 side of the rocking wall 45 is accommodated in the gap S between the bottom plate portion 34 and the base portion 271 of the stopper 27, and the movement of the rocking wall 45 in the direction away from the engagement pin 21 causes the stopper 27 to move. It is regulated by the base 271.
In this state, the swing wall 45 is configured not to interfere with the bottom plate portion 34 on the engagement pin 21 side, and when the engagement pin 21 is disposed at the connection preparation position, the engagement pin 21 of the swing wall 45. The movement of the oscillating wall 45 in the direction away from the engagement pin 21 is restricted while allowing the displacement to the side.

以下、かかる構成のカバー部40Aの場合の動作を説明する。
係合ピン21が連結準備位置(図7の(a)参照)に配置されている状態で、牽引車両8を旋回移動させて、連結アーム91の係合孔92が設けられた一端91a側と係合ピン21とを、係合ピン21の径方向(水平方向)で互いに近づく方向に相対的に移動させると、連結アーム91の一端91a側が、揺動壁45の係合ピン21とは反対側の面に当接する。
Hereinafter, the operation in the case of the cover portion 40A having such a configuration will be described.
In a state where the engagement pin 21 is disposed at the connection preparation position (see FIG. 7A), the tow vehicle 8 is swung and the one end 91a side where the engagement hole 92 of the connection arm 91 is provided, When the engaging pin 21 is moved relatively in the radial direction (horizontal direction) of the engaging pin 21 so as to approach each other, the one end 91 a side of the connecting arm 91 is opposite to the engaging pin 21 of the swing wall 45. Abuts against the side surface.

そうすると、揺動壁45は、係合ピン21に近づく方向の変位が許容されているので、揺動壁45は、連結アーム91の一端91a側により押されて、係合ピン21に近づく方向に揺動軸Y2周りに揺動する。これにより、連結アーム91の一端91a側は、揺動壁45と側壁部42の間に進入されることになる。   Then, since the displacement of the swing wall 45 in the direction approaching the engagement pin 21 is allowed, the swing wall 45 is pushed by the one end 91 a side of the connecting arm 91 and approaches the engagement pin 21. It swings around the swing axis Y2. As a result, the one end 91 a side of the connecting arm 91 enters between the swing wall 45 and the side wall portion 42.

そして、最終的に連結アーム91の一端91a側は、反対側の側壁部42に当接して、揺動壁45と側壁部42の間に保持された状態となる(図7の(a)参照)。   Finally, one end 91a side of the connecting arm 91 comes into contact with the opposite side wall portion 42 and is held between the swing wall 45 and the side wall portion 42 (see FIG. 7A). ).

なお、揺動壁45は、係合ピン21から離れる方向への変位が、ストッパ27の基部271により規制されているので、揺動壁45と側壁部42の間に進入した連結アーム91の一端91a側は、揺動壁45と側壁部42の間の係合ピン21との係合位置で保持されることになる。   In addition, since the displacement of the swing wall 45 in the direction away from the engagement pin 21 is restricted by the base portion 271 of the stopper 27, one end of the connecting arm 91 that has entered between the swing wall 45 and the side wall portion 42. The 91a side is held at the engaging position of the engaging pin 21 between the swing wall 45 and the side wall portion 42.

よって、この状態から係合ピン21を係合位置まで上昇させて係合孔92に係合させると(図7の(c)参照)、台車列9(台車90)と牽引車両8とが、連結装置2により連結された状態となる。   Therefore, when the engagement pin 21 is raised to the engagement position from this state and engaged with the engagement hole 92 (see (c) in FIG. 7), the carriage train 9 (the carriage 90) and the towing vehicle 8 are It will be in the state connected by the connection apparatus 2. FIG.

この状態において、カバー部40の揺動壁45と側壁部42は、支持板部35よりも上方に位置しており、連結アーム91が軸線X周りに回動しても、連結アーム91と揺動壁45や側壁部42とが互いに干渉しないようになっている。
そのため、台車90の牽引走行を開始した牽引車両8が旋回移動する際に、連結アーム91が揺動壁45や側壁部42と干渉して、牽引車両8の旋回移動が阻害されないようになっている。
In this state, the rocking wall 45 and the side wall portion 42 of the cover portion 40 are located above the support plate portion 35, and even if the connecting arm 91 rotates about the axis X, the rocking wall 45 and the side wall portion 42 swing with the connecting arm 91. The moving wall 45 and the side wall portion 42 do not interfere with each other.
Therefore, when the towing vehicle 8 that has started towing the cart 90 turns, the connecting arm 91 interferes with the swing wall 45 and the side wall portion 42 so that the turning movement of the towing vehicle 8 is not hindered. Yes.

さらに、シリンダ10を駆動して、係合ピン21を連結位置(図7の(c)参照)から、この連結位置よりも下方の連結解除位置(図7の(b)に移動させると、この係合ピン21の下方への移動に伴って、カバー部40の揺動壁45と側壁部42もまた、底板部34側の下方に変位することになる。   Further, when the cylinder 10 is driven and the engagement pin 21 is moved from the connection position (see FIG. 7C) to the connection release position below the connection position (FIG. 7B), As the engaging pin 21 moves downward, the rocking wall 45 and the side wall portion 42 of the cover portion 40 are also displaced downward on the bottom plate portion 34 side.

そうすると、係合ピン21は、上端21aを、連結アーム91の係合孔92よりも下方に配置させた状態となり、係合ピン21と係合孔92とが非係合状態になる。
さらに、係合ピン21の下方への移動に連動して底板部34側の下方に変位した揺動壁45は、下縁451を、ストッパ27の基部271よりも上方に配置させた状態になる。
If it does so, the engagement pin 21 will be in the state which has arrange | positioned the upper end 21a below the engagement hole 92 of the connection arm 91, and the engagement pin 21 and the engagement hole 92 will be in a non-engagement state.
Further, the rocking wall 45 displaced downward on the bottom plate portion 34 side in conjunction with the downward movement of the engagement pin 21 is in a state in which the lower edge 451 is disposed above the base portion 271 of the stopper 27. .

この状態において揺動壁45は、係合ピン21から離れる方向に変位しても、ストッパ27の基部271に干渉しない高さ位置に配置されているので、揺動壁45は、係合ピン21に近づく方向の変位と、係合ピン21から離れる方向への移動とが許容された状態となっている。   In this state, the oscillating wall 45 is disposed at a height position that does not interfere with the base portion 271 of the stopper 27 even if the oscillating wall 45 is displaced in a direction away from the engaging pin 21. In this state, the displacement in the direction approaching and the movement in the direction away from the engagement pin 21 are allowed.

よって、この状態で牽引車両8を旋回移動させて、連結アーム91の係合孔92が設けられた一端91a側と係合ピン21とを、係合ピン21の径方向(水平方向)で、互いに離れる方向に相対的に移動させて、連結アーム91の一端91a側を揺動壁45に接触させると、連結アーム91の一端91a側が接触した揺動壁45は、係合ピン21から離れる方向への移動が許容されているので、一端91aにより押されて、揺動軸Y1周りに揺動する。   Therefore, in this state, the tow vehicle 8 is turned to move the one end 91a side where the engagement hole 92 of the connection arm 91 is provided and the engagement pin 21 in the radial direction (horizontal direction) of the engagement pin 21. When the one end 91a side of the connecting arm 91 is brought into contact with the swinging wall 45 by moving relative to each other in a direction away from each other, the swinging wall 45 in contact with the one end 91a side of the connecting arm 91 is separated from the engagement pin 21. Is allowed to move to the swing axis Y1 and is swung around the swing axis Y1.

これにより、連結アーム91の一端91a側が、揺動壁45と側壁部42の間から外側に移動することになる。
そして、牽引車両8が旋回を続けると、連結アーム91がストッパ27のガイドアーム272の上面を摺動しながら移動して、最終的にストッパ27から連結アーム91が外れて、牽引車両8が台車列9(台車90)から切り離されることになる。
As a result, the one end 91 a side of the connecting arm 91 moves outward from between the swing wall 45 and the side wall portion 42.
When the towing vehicle 8 continues to turn, the connecting arm 91 moves while sliding on the upper surface of the guide arm 272 of the stopper 27, and finally the connecting arm 91 is detached from the stopper 27, so that the towing vehicle 8 is a carriage. It will be cut off from row 9 (cart 90).

以上の通り、変形例では、
(5)自走可能な牽引車両8に設けられており、当該牽引車両8に牽引される台車90(被牽引車両)備える連結アーム91の係合孔92に係合ピン21を係脱させて、牽引車両8と台車90との連結/連結解除を行う連結装置2であって、
