【発明の属する技術分野】
本発明は、異形長尺物の運搬用装置関するものである。
【0002】
【従来の技術】
従来、長尺物の車両による運搬技術としては、例えば、特開2002−59776号公報に記載のものが知られている。
この従来の技術には、長尺物を車両に積載して運搬する際に、長尺物の一端部側を前方車両に支持し、他端部側を後方車両に支持する運搬技術が記載されている。
【0003】
この従来の技術は、長尺物として長さ方向の大きさ,重量等に均等性のあるものを運搬対象としている。
【0004】
【発明が解決しようとする課題】
この従来の技術では、異形長尺物(長さ方向の大きさ,重量に均等性のない長尺物)を運搬対象にすると、前方車両および後方車両でそれぞれ異なる支持構造を備えなければならず、しかも安定した運搬姿勢を確保するためには、異なる支持構造の間での複雑な調整も必要となる。
このため、異形長尺物を運搬対象とするのが困難であるという問題点がある。
【0005】
なお、長尺物の車両による運搬では、長尺物の一端部側を車両に支持し、他端部側を車両から突出させたオーバハング式の積載形態が採られるのが一般的である。
しかしながら、オーバハング式の積載形態では、曲り角(曲がりくねった道等を含む)での異形長尺物を含めた車両の旋回径が大きく道路際の電柱,建屋等が障害となって通過が不能になることがあるという問題点がある。
一方、オーバハング式の積載形態が一般的であるため、長尺物の車両に対するオーバハング式に対応した積載,荷降等に係る設備,ノウハウ等が確立されており、異形長尺物においても積載形態の変更を望まないという要請がある。
【0006】
本発明は、このような問題点,要請を考慮してなされたもので、オーバハング式の積載形態で異形長尺物を運搬する際に、曲り角での旋回径を小さくすることのできる異形長尺物運搬用装置を提供することを課題とする。
【0007】

その際、支持台の下部支持枠は、断面が U 字状に形成されているので、異形長尺物の下部側面を確実に支持することができる。
また、前記端部支持枠に異形長尺物の基端側が嵌合される穴を形成することによって、異形長尺物をより確実に支持することができる。

【0019】
【発明の実施の形態】
以下、本発明に係る異形長尺物運搬用装置の実施の形態を図面に基づいて説明する。
【0020】
まず、本発明に係る異形長尺物運搬用装置の構成について説明する。
【0021】
この実施の形態では、風力発電の風車のブレード(例えば、長さが30mで重さ5t程度)からなる異形長尺物Bを運搬する装置を示してある。
【0022】
この実施の形態は、図1〜図5に示すように、車両1,支持台2,起伏機構3,重心調整機構4,旋回機構5,補助輪機構6を備えている。
【0023】
前記車両1は、前部に運転席(エンジン)11が設けられ、後部に荷台12が設けられた車輪走行式のトラックからなる。
【0024】
前記支持台2は、車両1の荷台12に旋回機構5を介して搭載されたもので、異形長尺物Bの長さ方向を横にした場合の下側を支え、車両1の荷台12のほぼ中央から後方へ少し突出するように延びる下部支持枠21と、異形長尺物Bの長さ方向を横にした場合の基端側(風車の回転軸に取付けられる側の端部)を支え、車両1の荷台12のほぼ中央で立上げられた端部支持枠22とがほぼL字形に組付けられてなる。
前記下部支持枠21は、異形長尺物Bの下側が嵌合されるように断面U字形に形成されている。
また、端部支持枠22には、異形長尺物Bの基端側が嵌合されるように穴構造(図示せず)が形成されている。したがって、この支持台2は、嵌合によって異形長尺物Bを確実に支持することができる。
なお、必要に応じて、異形長尺物Bの支持を補助するためのロック機構,緊縛具等が付設される。
【0025】
前記起伏機構3は、支持台2,旋回機構5の間に介装されたもので、支持台2の下部支持枠21,端部支持22のL字形の角部付近と、後述する旋回機構5の旋回台53とに取付けられ支持台2の起伏(上下方向に回動)を可能にする起伏軸31と、支持台2の下部支持枠21の中央部と後述する旋回機構5の旋回台53との間に配設され支持台2の起伏を駆動する油圧シリンダ32とからなる。
起伏軸31は、軸線が車両1の両側方向へ水平に配設されたピン構造からなる。
油圧シリンダ32は、支持台2を78度程度まで起立させることのできるストロークを有している。
【0026】
前記重心調整機構4は、旋回機構5に支持されたもので、後述する旋回機構5の旋回台53上の前方側寄りにスライド可能に載置された重り41と、後述する旋回機構5の旋回台53上の後方側寄りに支持され重り41をスライド駆動する油圧シリンダ42とからなる。
なお、重り41のスライド域は、起伏機構3の起伏軸31付近まで前後方向に確保されている。
【0027】
前記旋回機構5は、車両1の荷台12に直接的に搭載されたもので、車両1の荷台12に回転可能に支持された回転筒51と、回転筒51の内周に設けられた内歯車(図示せず)と、内歯車に噛合したギア52と、ギア52に連結された駆動モータ(図示せず)と、旋回筒51に支持され、荷台12の前後方向のほぼ全面に展開した旋回台53と、旋回台53の上の後方寄りに設けられた受座54とからなる。
旋回筒51,受座54は、起伏機構3の起伏軸31よりも後方側に位置している。
【0028】
前記補助輪機構6は、車両1の荷台12の両側にアウトリガー式に装備されたもので、車両1の荷台12に支持され、両側方向へ伸縮する2本の横アーム61と、横アーム61に支持され、上下に伸縮する2本ずつ合計4本の縦アーム62と、縦アーム62の下端にそれぞれ回動可能に支持された補助輪63と、縦アーム62を補強連結するテンション材64とからなる。
この補助輪機構6は、車両1の荷台12の後方側に位置している。
【0029】
つぎに、本発明に係る異形長尺物運搬用装置の操作,動作の説明に基づいて、異形長尺物を運搬する方法について説明する。
【0030】
図6〜図7には、運搬元から運搬先までの異形長尺物Bの積載,運搬,荷降の作業手順が示されている。
【0031】
まず、運搬元では、車両1の荷台12に搭載されている支持台2に、異形長尺物Bが積載される。
このとき、傾倒された支持台2に対して、異形長尺物Bが上方から吊降されたり側方から吊移動されたりして積載される。
なお、この積載作業では、車両1を安定化させるために、補助輪機構6の横アーム61,縦アーム62を伸張させ、補助輪63を接地させておくこともできる。
また、運搬元での異形長尺物Bの積載方向に制約がある場合には、旋回機構5を駆動して、支持台2の水平方向の向きを調整することもできる。
【0032】
前記支持台2に、異形長尺物Bが積載された状態(支持台2の長さ方向が車両1の前後方向へ向けられている)では、支持台2の下部支持枠21が旋回機構5の受座54に下支えされ、重心調整機構4の重り41が旋回機構5の旋回台53の上で前方側に位置されるため、異形長尺物Bが支持台2(車両1の荷台12)から長い突出長aで突出しても、安定したオーバハング式の積載が完成される。
【0033】
支持台2に異形長尺物Bが積載された後には、車両1が運搬先に向けて走行する。
【0034】
走行する車両1が、曲り角(曲がりくねった道等を含む)に到達した場合には、旋回径cから通過することが可能かどうか判断される。
通過不能と判断されると、車両1を停止させ、起伏機構3の油圧シリンダ32を駆動して支持台2を起立させる。
この結果、支持台2と一体的に異形長尺物Bも起立され、異形長尺物Bの支持台2(車両1の荷台12)からの突出長bが短くなり、旋回径dも小さくなる。
なお、重心調整機構4の重り41は、異形長尺物B,支持台2の重心移動による旋回機構5への偏荷重を避けるために、油圧シリンダ42によって、旋回機構5の旋回台53の上で後方側にスライドされる。
【0035】
この後、異形長尺物Bが起立された状態で、車両の走行が再開され、曲り角を通過する。
このとき、風や路面の傾斜状態で安定した走行が困難と判断された場合には、補助輪機構6の横アーム61,縦アーム62を伸張させ補助輪63を接地させる。
また、補助輪機構6の補助輪63を接地させても安定した走行が不能な場合や、起立した異形長尺物Bが、上方にある障害物を避けなければならない場合には、旋回機構5の図示されない駆動モータによりギア52を回転駆動し、旋回筒51,旋回台53を旋回させて、支持台2を介して異形長尺物Bを左右に旋回させて、重心を移動させて、先端部を移動させる(図1,図5参照)。
この異形長尺物Bの旋回では、車両1の荷台12をベースにして支持台2,起伏機構3が一体的に旋回機構5で旋回されるため、異形長尺物Bの起立状態が不安定になることはない。
【0036】
曲り角を通過した後には、再び車両1が停止される。
そして、起伏機構3,重心調整機構4,旋回機構5,補助輪機構6の逆の動作によって、異形長尺物Bが曲り角を通過する前の姿勢に復帰される。
なお、車両1の安定性を保持するためには、補助輪機構6の逆の動作による車両1の荷台12の両側部への格納は、最後に行うようにするのが好ましい。
【0037】
車両1が運搬先に到着した際には、車両1を停止させて、運搬元の積載作業と逆の荷降作業が行われる。
このとき、図7に示すように、補助輪機構6の横アーム61,縦アーム62を伸張させ補助輪63を接地させ、支持台2を起伏機構3で起立させるとともに、旋回機構5で左右に旋回させ、異形長尺物Bを起立させて向きを調整することで、吊上げによる荷降作業を容易にすることができる。
また、図8に示すように、補助輪機構6の横アーム61,縦アーム62を伸張させ補助輪63を接地させ、支持台2を旋回機構5で左右に旋回させ、異形長尺物Bを起立させずに向きを調整することで、周囲の障害物を避けて横移動による荷降作業を容易にすることができる。
【0038】
以上、図示した実施の形態の外に、異形長尺物Bとして、風力発電風車のブレード以外のものを対象とすることも可能である。
【0039】
さらに、起伏機構3,重心調整機構4を油圧シリンダ32,42ではなく、モータ,ギア,チェーン等で駆動する構成とすることも可能である。
【0040】
また、重心調整機構4の代わりに、車両1上の装置全体を起立に合わせて、前後方向に移動させ、重心を適正にすることも可能である。
【0041】
【発明の効果】
本発明に係る異形長尺物運搬用装置によれば、異形長尺物の運搬において、車両が曲り角を通過する際に、先端を自由にした状態で異形長尺物を起立させ、異形長尺物の車両からの突出長を短縮させることができるため、オーバハング式の積載形態の曲り角での旋回径を小さくすることができる効果がある。
【0042】
また起立された異形長尺物が旋回されることで、異形長尺物の重心が移動され、先端部が移動されるため、車両の安定走行が可能になるとともに、起立した異形長尺物が上方にある障害物を避けることが可能になる効果がある。
【0043】
さらに本発明に係る異形長尺物運搬用装置は、前述の効果に加えて、異形長尺物を、支持台を介して車両に支持するため、異形長尺物を安定して積載することができる効果がある。
【0044】
また支持台,起伏機構が車両をベースにして旋回機構で一体的に旋回されるため、異形長尺物の起立状態が不安定になることがない効果がある。
【0045】
また車両の両側部で補助輪機構がアウトリガー式に使用されるため、走行時や異形長尺物の積載,荷降時の車両の姿勢が安定化される効果がある。
【0046】
また重心調整用重りが車両上で前後に移動するため、異形長尺物が起立した際でも重心位置を最適な位置に保つことができる。

[0032]
In a state in which the deformed long object B is loaded on the support table 2 (the length direction of the support table 2 is directed in the front-rear direction of the vehicle 1), the lower support frame 21 of the support table 2 is the turning mechanism 5. Since the weight 41 of the center-of-gravity adjusting mechanism 4 is positioned on the front side on the swivel base 53 of the turning mechanism 5, the deformed long object B is supported by the support base 2 (the loading platform 12 of the vehicle 1). Even if it protrudes with a long protrusion length a, stable overhang type loading is completed.
[0033]
After the deformed long object B is loaded on the support base 2, the vehicle 1 travels toward the transportation destination.
[0034]
When the traveling vehicle 1 reaches a corner (including a winding road), it is determined whether or not the vehicle 1 can pass from the turning radius c.
If it is determined that the vehicle cannot pass, the vehicle 1 is stopped and the hydraulic cylinder 32 of the hoisting mechanism 3 is driven to erect the support base 2.
As a result, the odd-shaped long object B is also erected integrally with the support base 2, the protruding length b of the odd-shaped long object B from the support base 2 (the loading platform 12 of the vehicle 1) is shortened, and the turning diameter d is also small. .
The weight 41 of the center-of-gravity adjusting mechanism 4 is provided on the swivel base 53 of the swivel mechanism 5 by the hydraulic cylinder 42 in order to avoid an uneven load on the swivel mechanism 5 due to the deformation of the deformed long object B and the support base 2. To slide backwards.

[0036]
After passing the corner, the vehicle 1 is stopped again.
And by the reverse operation of the hoisting mechanism 3, the center-of-gravity adjustment mechanism 4, the turning mechanism 5, and the auxiliary wheel mechanism 6, the deformed elongated object B is returned to the posture before passing through the corner.
In order to maintain the stability of the vehicle 1 can be stored in a both side portions of the bed 12 of the vehicle 1 by the reverse of the operation of the auxiliary wheel mechanism 6 is preferably to finally performed.
[0037]
When the vehicle 1 arrives at the transportation destination, the vehicle 1 is stopped and the unloading operation reverse to the loading operation at the transportation source is performed.
At this time, as shown in FIG. 7, the horizontal arm 61 and the vertical arm 62 of the auxiliary wheel mechanism 6 are extended to ground the auxiliary wheel 63, and the support base 2 is raised by the hoisting mechanism 3 and left and right by the turning mechanism 5. The unloading work by lifting can be facilitated by turning and adjusting the direction by raising the irregular long object B.
Further, as shown in FIG. 8, the horizontal arm 61 and the vertical arm 62 of the auxiliary wheel mechanism 6 are extended to ground the auxiliary wheel 63, the support base 2 is turned left and right by the turning mechanism 5, and the deformed long object B is By adjusting the direction without standing up, it is possible to avoid surrounding obstacles and facilitate unloading work by lateral movement.
[0038]
