Description

本発明は、軌道走行用車両搭載クレーン装置に関するものである。   The present invention relates to a track-mounted vehicle-mounted crane device.

従来のクレーン装置は、先端にフックを有するブームを取付けた回転支柱が、ベース上に鉛直状に立設された固定支柱に回転自在に取付けられており、回転支柱を軸心廻りに回転して、ブームを旋回させることができるものが知られている（例えば、特許文献１参照）。回転支柱は、固定支柱と同一の軸心廻りに回転するので、ベースを水平な面上に載置して使用すれば、ブームは水平旋回させることができる。
特願２００３−３４１９８３公報 In a conventional crane device, a rotating column with a boom having a hook at the tip is rotatably mounted on a fixed column vertically installed on the base, and the rotating column is rotated around its axis. The thing which can turn a boom is known (for example, refer to patent documents 1). Since the rotary support rotates about the same axis as the fixed support, the boom can be turned horizontally if the base is placed on a horizontal surface.
Japanese Patent Application No. 2003-341983

従来のこのクレーン装置を鉄道軌道走行用の車両に搭載して、軌道の保守点検用に用いるものとすれば、カーブの存在する場所ではカントがあって車両が左右に傾く。そのため、回転支柱及び固定支柱が共に鉛直方向から傾斜した状態となり、回転支柱の回転軸心が傾斜するので、ブームを水平旋回させることができなくなり、ブームがその自重により下傾姿勢に不意に回転する虞れがあり非常に危険である。また、ブームを上傾姿勢へと回転させるためには労力を要するため、荷物搬送の作業効率が悪い。   If this conventional crane apparatus is mounted on a railway track running vehicle and used for track maintenance and inspection, there is a cant in a place where a curve exists, and the vehicle tilts to the left and right. For this reason, both the rotating support column and the fixed support column are inclined from the vertical direction, and the rotation axis of the rotating support column is inclined, so that the boom cannot be turned horizontally, and the boom rotates unexpectedly in a downward inclined posture due to its own weight. It is very dangerous. Moreover, since labor is required to rotate the boom to the tilted posture, the work efficiency of the load transportation is poor.

そこで、本発明は、線路軌道上でカントのある場所の作業においても、ブームを水平旋回させることができる軌道走行用車両搭載クレーン装置を提供することを目的とする。   Therefore, an object of the present invention is to provide a track-mounted vehicle-mounted crane device that can horizontally swing a boom even when working on a track where there is a cant.

上記目的を達成するために、本発明に係る軌道走行用車両搭載クレーン装置は、軌道走行用車両に搭載固定される下柱部の上端に、アクチュエータにて傾動自在な傾動盤を枢着し、該傾動盤に回転盤を設けて、該回転盤を介して上柱部を立設し、該上柱部にブームを付設したものである。   In order to achieve the above-described object, a crane device for a track traveling vehicle according to the present invention has a tilting plate pivotable by an actuator pivotally attached to an upper end of a lower pillar portion mounted and fixed to the track traveling vehicle. A rotating disk is provided on the tilting disk, an upper column part is erected through the rotating disk, and a boom is attached to the upper column part.

また、上記傾動盤の左右方向一側部が、上記下柱部の上端に前後方向水平軸心廻りに傾動自在に枢着され、かつ、上記傾動盤の他側部と上記下柱部が、上記アクチュエータによって連結された。
また、上記下柱部が鉛直に向く基本姿勢状態では、上記アクチュエータが中間まで伸長した状態で上記傾動盤を水平に保持するように構成されている。
また、該下柱部に対する該傾動盤の傾動を防止するロック機構を備えた。 Further, one side portion in the left-right direction of the tilting plate is pivotally attached to the upper end of the lower column portion so as to be tiltable around a horizontal axis in the front-rear direction, and the other side portion of the tilting plate and the lower column portion are Connected by the actuator.
Further, in the basic posture state in which the lower column portion is vertically oriented, the tilting plate is held horizontally with the actuator extended to the middle.
Further, a lock mechanism for preventing the tilting plate from tilting with respect to the lower column part is provided.

本発明は、次のような著大な効果を奏する。
本発明に係る軌道走行用車両搭載クレーン装置は、軌道走行用車両に搭載固定される下柱部の上端に、アクチュエータにて傾動自在な傾動盤を枢着し、傾動盤に回転盤を設けて、回転盤を介して、ブームを付設した上柱部を立設したので、車両を停車させた場所のカントの大きさに応じて、傾動盤を傾動させることで、上柱部の回転軸心を鉛直方向に合わせることにより、ブームを水平面内にて旋回（水平旋回）させることが可能となる。従って、カントのある軌道上に車両を停止させる場合であっても、ブームを水平旋回させることができるので、ブームがその自重により不意に下傾姿勢の位置へ自走する事故を防止できる。また、逆に、ブームを上傾姿勢位置へと旋回させるのに過大な人力を要するようなこともなく、効率よく保線作業等を行うことができる。また、ブームを水平旋回させることができることから、高さが同じ程度の場所への吊り荷の移動であれば、昇降微調整をチェーンブロック等で行う必要がないので、作業をスムーズに行うことができる。 The present invention has the following remarkable effects.
In the track traveling vehicle mounted crane apparatus according to the present invention, a tilting plate that can be tilted by an actuator is pivotally attached to an upper end of a lower column portion that is mounted and fixed on the track traveling vehicle, and a rotating disc is provided on the tilting plate. Since the upper column part with the boom is erected through the rotating disk, the rotation axis of the upper column part is tilted according to the size of the cant where the vehicle is stopped. By adjusting to the vertical direction, the boom can be turned (horizontal turning) in a horizontal plane. Therefore, even when the vehicle is stopped on a canted track, the boom can be turned horizontally, so that it is possible to prevent an accident in which the boom unexpectedly self-runs to a position of a downwardly inclined posture due to its own weight. On the other hand, it is possible to efficiently perform the track maintenance work and the like without requiring excessive human power to turn the boom to the tilted position. In addition, since the boom can be swiveled horizontally, it is not necessary to perform fine adjustment of the lift with a chain block or the like if the suspended load is moved to a place with the same height. it can.

The tilting board 3 is held horizontally. In a work place where the track R does not have a cant, the work is performed with the crane device in the basic posture state, and the boom 6 is turned in the horizontal plane H. Further, the crane device is transported (that is, transported by traveling of the vehicle 7) in a state where the tilting plate 3 is prevented from tilting with respect to the lower column part 1 by the lock mechanism 9 as a basic posture state.
The actuator 2 is a hydraulic single acting / returning cylinder or the like. An electric pump may be provided in place of the manual hydraulic pump 28. Alternatively, the actuator 2 may be an electric reciprocating cylinder.

次に、本発明の軌道走行用車両搭載クレーン装置の作用及び使用方法について説明する。
カントのない作業場所では、図２〜図４に示したように、傾動盤３が下柱部１上の平板部13に対して平行となる基本姿勢状態にて、保線作業を行う。即ち、下柱部１・上柱部５の軸心Ｐ1 ，Ｐ5 が同一線上となる状態にて、ブーム６が水平面Ｈ内で旋回されて、車両７の両側の保線作業────重量物の車両７からの積下ろしや車両７への積込み等の作業────を行うことができる。 Next, the operation and method of use of the track traveling vehicle mounted crane apparatus of the present invention will be described.
In a work place without a cant, as shown in FIGS. 2 to 4, the track maintenance work is performed in a basic posture state in which the tilting plate 3 is parallel to the flat plate portion 13 on the lower column portion 1. That is, with the axes P 1 and P 5 of the lower pillar portion 1 and the upper pillar portion 5 being on the same line, the boom 6 is turned in the horizontal plane H, and the track maintenance work on both sides of the vehicle 7 is performed. Operations such as unloading heavy objects from the vehicle 7 and loading into the vehicle 7 can be performed.

次に、図１のように、軌道Ｒにカントが生じて、車両７の一側が上傾状となる場所へ移動して作業を行う場合について説明する。先ず、図２，図３，図４に示した基本姿勢状態の装置から、ロック機構９の固定ピン19を抜く。そして、手動油圧ポンプ28の操作レバー28ａを揺動操作してアクチュエータ２へ油圧をかけて、ロッド部25をシリンダ部24から伸長させ、傾動盤３を、その他側部32が平板部13の他側13ｂから離間するように、軸心Ｌ廻りに傾動させて、水平調整器26を見ながらブーム６を図１のように水平面Ｈ上に向ける。この図１では、ブーム６が左右方向他側へ向けられており、左右方向他側の保線作業が行われる。
そして、傾動盤３及び回転盤４が水平であり、かつ、軸心Ｐ5 が鉛直方向を向いているので、ブーム６をスムーズに水平面Ｈ内で（人力により）旋回させて、図５に示したように、左右方向一側へ向けることができる。これにより、ブーム６がその自重によって不意に下傾姿勢の位置へと自走回転する事故を防止でき、また、逆に、上傾姿勢へ旋回させるのに過大な人力を要するようなこともない。 Next, as shown in FIG. 1, a case will be described in which a cant is generated on the track R and one side of the vehicle 7 moves to a place where the vehicle 7 is inclined upward. First, the fixing pin 19 of the lock mechanism 9 is removed from the apparatus in the basic posture state shown in FIGS. Then, the operating lever 28a of the manual hydraulic pump 28 is swung to apply hydraulic pressure to the actuator 2 so that the rod portion 25 extends from the cylinder portion 24, the tilting plate 3 and the other side portion 32 other than the flat plate portion 13. Inclined around the axis L so as to be separated from the side 13b, the boom 6 is directed on the horizontal plane H as shown in FIG. In FIG. 1, the boom 6 is directed to the other side in the left-right direction, and the track maintenance work on the other side in the left-right direction is performed.
Then, a tilt plate 3 and the rotating disk 4 is horizontally and, since the axis P 5 are vertically oriented, (by human) in a horizontal plane H of the boom 6 smoothly pivoted, shown in FIG. 5 As shown, it can be directed to one side in the left-right direction. As a result, it is possible to prevent an accident in which the boom 6 is unintentionally rotated to the position of the downward tilting posture by its own weight, and conversely, excessive human power is not required to turn to the upward tilting posture. .

また、図示省略するが、軌道走行用車両７が左右方向他側へ上傾状となる（カントのある）場所で作業を行う場合については、手動油圧ポンプ28を操作して、アクチュエータ２のロッド部25をシリンダ部24内へ収納させて、傾動盤３を、その他側部32が平板部13の他側13ｂに接近する方向へ軸心Ｌ廻りに傾動させて、水平調整器26を見ながら水平方向Ｈに向ける。これにより、図１，図５で説明したと同様に、ブーム６をスムーズに水平面Ｈ内で旋回させることができ、安全作業を行い得ると共に、過大な人力が不要である。
なお、本発明は上述の実施の形態に限定されず設計変更自由であって、脚枠部材12の形状と構造は各種設計変更可能であると共に、下柱部１を脚枠部材12の左右中央（近傍）位置に立設することも可能であり、また、台車46に直接的に下柱部１を固着（立設）することもできる。また、上柱部５に対してブーム６を（起伏アクチュエータ等によって）傾動自在な構造としても良く、そのときも、ブーム６のその傾動（起伏）角度を一定としたままで、吊荷を水平面Ｈ内で安全かつスムーズに旋回させることができる。 Although not shown in the drawings, when the work is performed in a place where the orbital vehicle 7 is inclined upward (with a cant) to the other side in the left-right direction, the manual hydraulic pump 28 is operated to operate the rod of the actuator 2. The part 25 is accommodated in the cylinder part 24, and the tilting plate 3 is tilted around the axis L in the direction in which the other side part 32 approaches the other side 13b of the flat plate part 13 while looking at the horizontal adjuster 26. Direct in the horizontal direction H. Thereby, like FIG.1, FIG.5, the boom 6 can be smoothly swung in the horizontal surface H, while being able to perform a safe operation | work, excessive human power is unnecessary.
The present invention is not limited to the above-described embodiment, and the design can be freely changed. The shape and structure of the leg frame member 12 can be changed in various designs. It is possible to stand in the (near) position, and the lower pillar portion 1 can be fixed (standing) directly to the carriage 46. Further, the boom 6 may be structured to be tiltable (by a hoisting actuator or the like) with respect to the upper column part 5, and at that time, the suspended load is placed on a horizontal plane while keeping the tilting (hunging) angle of the boom 6 constant. It can be turned safely and smoothly in H.

以上のように、本発明に係る軌道走行用車両搭載クレーン装置は、軌道走行用車両７に搭載固定される下柱部１の上端10に、アクチュエータ２にて傾動自在な傾動盤３を枢着し、傾動盤３に回転盤４を設けて、回転盤４を介して上柱部５を立設し、上柱部５にブーム６を付設したので、車両７を停車させた場所における軌道Ｒのカントの大きさに応じて、傾動盤３を傾動させて、上柱部５及び回転盤４の回転軸心Ｐ5 を鉛直方向に合わせ、ブーム６を水平面Ｈ内で旋回できる。従って、カントのある軌道Ｒ上に車両７を停止させて保線作業を行う場合であっても、ブーム６を確実に水平旋回させることができる。従って、ブームがその自重により不意に下傾姿勢の位置へ自走する事故を防止できる。また、逆に、ブームを上傾姿勢位置へと旋回させるのに過大な人力を要するようなこともなく、特に、人力による簡易のクレーン装置として好適な発明である。また、ブームを水平旋回させることができることから、高さが同じ程度の場所への吊り荷の移動であれば、昇降微調整をチェーンブロック等で行う必要がないので、作業をスムーズに行うことができる。 As described above, in the track traveling vehicle-mounted crane device according to the present invention, the tilting plate 3 that can be tilted by the actuator 2 is pivotally attached to the upper end 10 of the lower column portion 1 mounted and fixed on the track traveling vehicle 7. Since the rotating disk 4 is provided on the tilting disk 3, the upper column part 5 is erected via the rotating disk 4, and the boom 6 is attached to the upper column part 5, the track R at the place where the vehicle 7 is stopped. In accordance with the size of the cant, the tilting plate 3 is tilted so that the upper column part 5 and the rotation axis P 5 of the rotating plate 4 are aligned in the vertical direction, and the boom 6 can be turned in the horizontal plane H. Therefore, even when the vehicle 7 is stopped on the canted track R and the track maintenance work is performed, the boom 6 can be reliably turned horizontally. Therefore, it is possible to prevent an accident in which the boom is undesirably self-propelled to the position of the downwardly inclined posture due to its own weight. On the other hand, it does not require excessive human power to turn the boom to the upward tilted position, and is particularly suitable as a simple crane device using human power. In addition, since the boom can be swiveled horizontally, it is not necessary to perform fine adjustment of the lift with a chain block or the like if the suspended load is moved to a place with the same height. it can.

また、傾動盤３の左右方向一側部31が、下柱部１の上端10に前後方向水平軸心Ｌ廻りに傾動自在に枢着され、かつ、傾動盤３の他側部32と下柱部１が、アクチュエータ２によって連結されているので、アクチュエータ２を伸縮動させるだけで、傾動盤３を所望の状態（水平状態）に傾動させることができる。このように、簡素な構成ながら、確実にブーム６を水平面Ｈ内で旋回させることができる。   Further, one side 31 in the left-right direction of the tilting plate 3 is pivotally attached to the upper end 10 of the lower column 1 so as to be tiltable about the horizontal axis L in the front-rear direction, and the other side 32 of the tilting plate 3 and the lower column Since the part 1 is connected by the actuator 2, the tilting board 3 can be tilted to a desired state (horizontal state) only by expanding and contracting the actuator 2. In this way, the boom 6 can be reliably turned in the horizontal plane H with a simple configuration.

また、下柱部１が鉛直に向く基本姿勢状態では、アクチュエータ２が中間まで伸長した状態で傾動盤３を水平に保持するように構成されているので、アクチュエータ２を縮める（ロッド部25をシリンダ部24内に収納させる）ことで、傾動盤３の他側部32を下柱部１の上端10へ接近させることができ、かつ、アクチュエータ２を伸長させる（ロッド部25をシリンダ部24から突出させる）ことで、傾動盤３の他側部32を下柱部１の上端10から離間させることができる。このように、アクチュエータ２の直線作動によって、傾動盤３の傾動を行うことができるので、簡素な構成にすることができ、しかも、軌道Ｒが右上がりと左上がりのいずれのカントであっても、対応可能となる。   Further, in the basic posture state in which the lower column portion 1 is oriented vertically, the actuator 2 is contracted because the actuator 2 is contracted (the rod portion 25 is connected to the cylinder 25). The other side portion 32 of the tilting plate 3 can be brought closer to the upper end 10 of the lower column portion 1 and the actuator 2 is extended (the rod portion 25 protrudes from the cylinder portion 24). By doing so, the other side portion 32 of the tilting plate 3 can be separated from the upper end 10 of the lower column portion 1. Thus, since the tilting plate 3 can be tilted by the linear operation of the actuator 2, a simple configuration can be achieved, and the trajectory R can be lifted to the right or left. It becomes possible to respond.

また、下柱部１に対する傾動盤３の傾動を防止するロック機構９を備えたので、下柱部１に対して上柱部５やブーム６が揺動するのが防がれて、安全に搬送できる。   Further, since the lock mechanism 9 for preventing the tilting plate 3 from tilting with respect to the lower column portion 1 is provided, the upper column portion 5 and the boom 6 are prevented from swinging with respect to the lower column portion 1 and can be safely operated. Can be transported.
