Description

【０００１】
【発明の属する技術分野】
この発明は、重量物用パレットに関し、特に円筒形状のコイル等の重量物をタンクコンテナ専用セミトレーラー等に積載するために用いる重量物用パレットに関するものである。
【０００２】
【従来の技術】
従来、円筒形状のコイル等の重量物を輸送する場合は、重量物の積載に適した平床トレーラーに直接コイル等を積載して輸送を行っていた。
【０００３】
また、他の既存の重量物輸送用車両として、タンクコンテナ専用セミトレーラーが知られていたが、搭載可能なコンテナは専用タンクコンテナにのみ限定されており、他の積載物の輸送には供されていなかった。
【０００４】
【発明が解決しようとする課題】
上記のような従来のコイルの輸送方法では、１つ当たり数トンもの重量を有するコイルを同時に複数個輸送するためには、輸送車両として４０トンや５０トンの積載量を有する平床トレーラー等を使用するしかなかった。
【０００５】
また、平床トレーラーにコイル等を積載する場合は、荷台上に敷板等を敷設し、その上に直接コイル等を積載していたため、荷台上でのコイル等の移動を防止するために木材等を使用して、別途コイル等を固定する作業が必要であった。更に、平床トレーラーではコイル等の形状の重量物に特に適した荷台ではないため、荷台上における積載位置や積載物の設置方向等が規定されておらず、積み下ろし作業自体にも、特別の配慮が必要であった。
【０００６】
一方、重量物輸送用に供される車両の中で、上述のようにパレットごと積載物を搭載可能なものとして、タンクコンテナ専用セミトレーラーが知られていたが、従来は専用のタンクコンテナの搭載にのみ限定されていた。なぜなら、タンクコンテナ専用セミトレーラーは搭載される専用コンテナの荷重をその四隅のみで支持する構造をとるため、タンクコンテナ専用セミトレーラーをタンクコンテナ以外の積載物の輸送に使用するためには、特有の荷重条件を満たす強度と構造を有するコンテナパレットが必要とされるからである。
【０００７】
この発明は上記のような課題を解決するためになされたもので、円筒形状のコイル等の重量物を積載するためのパレットで、タンクコンテナ専用セミトレーラーにも搭載することが可能となる構造を備えた重量物用パレットを提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記の目的を達成するために、請求項１記載の発明は、矩形形状の四隅の位置においてのみ支持され、円筒形状のコイル等の重量物を積載するための重量物用パレットであって、各々が平行に配置され、各々のその上面が互いに近づく方向に対して下方に傾斜する傾斜板を有し、傾斜板の各々の上で重量物の外周側壁を支持することができる１対の支持部材と、支持部材の軸方向に直交する方向に配置され、支持部材の各々の両端部を支持する１対の外枠部材と、外枠部材の各々の両端部側に設けられ、四隅の位置に対応する４つの被支持部材とを備えたものである。
【０００９】
このように構成すると、円筒形状の積載物の中心軸と直交する方向への転がりが阻止されると共に、重量物の荷重が支持部材及び外枠部材を介して被支持部材に伝達される。
【００１０】
請求項２記載の発明は、請求項１記載の発明の構成において、支持部材の各々は、傾斜板の下方において軸方向に延びると共に水平に配置された矩形形状の底板と、底板の上部のほぼ中央部と傾斜板の下面のほぼ中央部との間を垂直方向に架け渡すように接続された矩形形状の支持板と、軸方向と直交する方向に所定間隔で配置され、傾斜板の外方側の下面と支持板の外方側の面と底板の外方側の上面とにその外縁が接した状態で接続された複数の第１のリブ板と、軸方向と直交する方向に所定間隔で配置され、傾斜板の内方側の下面と支持板の内方側の面と底板の内方側の上面とにその外縁が接した状態で接続された複数の第２のリブ板とを含むものである。
【００１１】
このように構成すると、傾斜板にかかる荷重が、支持板と複数の第１のリブ板と複数の第２のリブ板とを介して底板にも伝達されると共に、支持部材の断面二次モーメントが増加する。
【００１２】
請求項３記載の発明は、請求項１又は請求項２記載の発明の構成において、支持部材の各々は軸方向に平行な軸を中心として対称形状を有しており、傾斜板の各々は、軸方向の所定範囲における軸方向と直交する方向の幅が、所定範囲外における幅より大きくなるように形成されたものである。
【００１３】
このように構成すると、傾斜板上面において円筒形状重量物の外周側壁を支持することのできる範囲が大きくなる。
【００１４】
請求項４記載の発明は、請求項１から請求項３に記載の発明の構成において、
軸方向と直交する方向において、傾斜板の斜面上端部から斜面下端部に向かって傾斜板の上面に対してほぼ垂直になるように設置することができるほぼ矩形形状の移動阻止板と、斜面上端部から所定範囲において傾斜板の上面に固定され、移動阻止板を両面から支持する第１の固定具と、斜面下端部から所定範囲において傾斜板の上面に固定され、移動阻止板を両面から支持すると共に、移動阻止板の斜面下端部方向への移動を阻止する手段を備えた第２の固定具とからなる移動阻止手段を更に備えたものである。
【００１５】
このように構成すると、移動阻止板が第１の固定具と第２の固定具とを介して傾斜板上面に着脱自在に設置される。
【００１６】
請求項５記載の発明は、請求項２記載の発明の構成において、第１のリブ板と第２のリブ板とは同数であり、各々は同一面内に配置され、傾斜板の斜面上端部から斜面下端部に向かって傾斜板の上面に対してほぼ垂直となるように設置することができるほぼ矩形形状の移動阻止板と、移動阻止板の長手方向の一方端部に形成された被連結部と、移動阻止板の長手方向の他方端部において移動阻止板を挟むように接続された一対の平板状の第１の係止板とを備え、第１の係止板の各々の一部と移動阻止板の設置側の辺との間に一定の第１スペースが形成された移動阻止部材と、被連結部に着脱自在に係合し、移動阻止板を挟むように配置される一対の平板状の第２の係止板を備え、係合時において第２の係止板の各々の一部と移動阻止板の設置側の辺との間に一定の第２スペースが形成される固定部材とからなる移動阻止手段を更に備え、使用時において、第１スペースに傾斜板の斜面下端部が位置し、且つ第１の係止板の各々の間に第２のリブ板の１つが位置するように移動阻止部材を取り付け、この状態で固定部材を移動阻止部材の被連結部に係合させて、第２スペースに傾斜板の斜面上端部が位置し、且つ第２の係止板の各々の間に第２のリブ板の１つと同一面内に位置する第１のリブ板の１つが位置するように固定部材を取り付けるものである。
【００１７】
このように構成すると、移動阻止部材と固定部材とが、傾斜板と第１のリブ板と第２のリブ板とを介して傾斜板上面に着脱自在に設置される。
【００１８】
【発明の効果】
以上説明したように、請求項１記載の発明は、円筒形状の積載物が安定して保持されると共に、重量物の荷重が支持部材及び外枠部材を介して被支持部材に伝達されるので、タンクコンテナ専用セミトレーラー等の四隅で支持する輸送手段での輸送が可能となる。
【００１９】
請求項２記載の発明は、請求項１記載の発明の効果に加えて、傾斜板にかかる重量物の荷重が支持板と第１のリブ板と第２のリブ板とを介して底板にも分散されると共に、支持部材の断面二次モーメントが増加するので支持部材の強度が増す。
【００２０】
請求項３記載の発明は、請求項１又は請求項２記載の発明の効果に加えて、より径の大きなコイル等の重量物を積載することが可能となる。
【００２１】
請求項４記載の発明は、請求項１から請求項３に記載のいずれかの発明の効果に加えて、傾斜板上に設置した移動阻止板によってコイル等の重量物の軸方向への移動を阻止することが可能となる。
【００２２】
請求項５記載の発明は、請求項２記載の発明の効果に加えて、移動阻止部材と固定部材とが傾斜板と第１のリブ板と第２のリブ板とを介して傾斜板上に着脱自在に取り付けられるため、傾斜板上に加工を施すことなく任意の第１のリブ板及び第２のリブ板の位置において、コイル等の重量物の軸方向への移動を阻止することが可能となる。
【００２３】
【発明の実施の形態】
図１はこの発明の第１の実施の形態による重量物用パレットの使用状態を示した分解斜視図である。
【００２４】
図１を参照して、重量物用パレット１は一対の支持部材１３ａ及び１３ｂが平行になるよう配置され、これらの支持部材１３ａ及び１３ｂの両端部を支持するように外枠部材２ａ及び２ｂが支持部材１３ａ及び１３ｂの軸方向に直交する方法に配置されている。そして、支持部材１３ａ及び１３ｂの各々の両端部と外枠部材２ａ及び２ｂが互いに溶接接合されている。重量物用パレット１の四隅の位置、すなわち外枠部材２ａ及び２ｂの各々の両端の下部には、コンテナシャーシ１４により支持されるコーナフィティング８ａ〜８ｄが取り付けられている。外枠部材２ａ及び２ｂの各々の両端部にはまた、コーナー板１２ａ〜１２ｄが取り付けられ、これらのコーナー板１２ａ〜１２ｄを重量物用パレット１の長手方向に架け渡すように、上部には上部ガイド９ａ及び９ｂが、下部には下部ガイド１０ａ及び１０ｂが取り付けられている。
【００２５】
支持部材１３ａ及び１３ｂの各々の上部には、互いに近づく向きに下降し円筒形状積載物の外周側壁を支持することができる傾斜面が形成されており、この支持部材１３ａ及び１３ｂの両方の傾斜面に渡ってコイル１１ａ及び１１ｂが積載されている。そして、コイル１１ａ及び１１ｂは、ワイヤーロープ等でその外周側壁を囲うように支持部材１３ａ及び１３ｂに結束されており、コイル１１ａ及び１１ｂの軸と直交する方向への移動がより強固に阻止されている。
【００２６】
タンクコンテナ用セミトレーラーのコンテナシャーシ１４は、その上部に、矩形形状の四隅に位置するツイストロックピン１５ａ〜１５ｄが取り付けられており、この４点のツイストロックピン１５ａ〜１５ｄを介してのみ、搭載される専用パレットを支持できる構造を有している。
【００２７】
重量物用パレット１をコンテナシャーシ１４に搭載する場合は、その四隅に取り付けられた被支持部であるコーナフィティング８ａ〜８ｄの各々を、対応する位置のツイストロックピン１５ａ〜１５ｄによって支持するように連結する。
【００２８】
また、重量物用パレット１には、輸送中の積載物の保護のために幌装置１７を取り付けることが可能であり、その取り付けは、幌装置１７の下部と重量物用パレット１の長手方向に平行に取り付けられた上部ガイド９の各々及び下部ガイド１０の各々とを図示しない連結手段によって接続することにより行われる。
【００２９】
図２は図１に示した重量物用パレットの斜視図であり、図３は図２のＩＩＩ−ＩＩＩラインの断面図であり、図４は図２のＩＶ−ＩＶラインの断面図である。
【００３０】
図２から図４を参照して、重量物用パレット１における一方の支持部材１３ａは、他方の支持部材１３ｂへと近づく方向に対して下方に約３５度の傾斜がつけられた傾斜板３ａと、傾斜板３ａの下方に位置し水平に配置された底板５ａと、傾斜板３ａの下面のほぼ中央と底板５ａの上面のほぼ中央を架け渡すように垂直に配置され、互いに溶接接合された支持板４ａとから構成される。傾斜板３ａは、その軸方向のほぼ中央から一定の範囲において、他の部分より幅が広くなるように幅広部１８ａが形成されている。更に、支持部材１３ａはその軸方向と直交する方向に取り付けられ、所定の間隔で取り付けられた第１のリブ板６ａ〜６ｋと第２のリブ板１９ａ〜１９ｋとを含む。第１のリブ板６ａ〜６ｋは、傾斜板３ａの外方の下面と、支持板４ａの外方の面と、底板５ａの外方の上面とにその端縁が溶接接合されている。第２のリブ板１９ａ〜１９ｋは傾斜板３ａの内方の下面と、支持板４ａの内方の面と、底板５ａの内方の上面とにその端縁が溶接接合されている。また、第１のリブ板６と第２のリブ板１９とは同数で、且つ各々が同一面内に含まれるよう配置されている。
【００３１】
支持部材１３ｂもまた、傾斜板３ｂと支持板４ｂと底板５ｂと第１のリブ板７ａ〜７ｋと第２のリブ板２０ａ〜２０ｋとから構成され、支持部材１３ａとはそれらの軸方向に平行な軸を中心として対称形状を有している。
【００３２】
外枠部材２ａ及び２ｂは互いに平行に配置されたＨ型鋼又はＩ型鋼よりなり、各々のＨ型鋼等における平行な二面が水平になる向きに配置されている。
【００３３】
支持部材１３ａ及び１３ｂの端部は、外枠部材２ａ及び２ｂの内部に挿入され、外枠部材２ａ及び２ｂの垂直な面に接合されている。すなわち、傾斜板３ａ及び３ｂの各々の両端部と、支持板４ａ及び４ｂの各々の両端部と、底板５ａ及び５ｂの各々の両端部とが、外枠部材２ａ及び２ｂに直接接合されている。
【００３４】
このように支持部材１３ａ及び１３ｂの各々の両端部を外枠部材２ａ及び２ｂでのみ支持しているため、傾斜板３ａ及び３ｂ上にコイル１１等の重量物を積載すると、傾斜板３ａ及び３ｂにかかる荷重は外枠部材１３ａ及び１３ｂを構成する各部に分散しつつ、すべての荷重が外枠部材２ａ及び２ｂに伝達されることになる。
【００３５】
更に、外枠部材２ａ及び２ｂの各々の両端の下部には、外枠部材２ａ及び２ｂを支持するためのコーナフィティング８ａ〜８ｄが取り付けられており、外枠部材２ａ及び２ｂにかかる荷重は最終的にはすべて、コーナフィティング８ａ〜８ｄに伝達されることになる。したがって、重量物用パレット１は四隅のコーナフィティング８ａ〜８ｄのみで荷重が支持されるため、タンクコンテナ専用セミトレーラーに搭載することが可能となる。
【００３６】
ここで、重量物用パレット１の使用状態について説明する。図３を参照して、コイル１１を積載すると、その外周側壁部分が一対の傾斜板３ａ及び３ｂによって支持され、コイル１１の軸と直交する方向への転がりが阻止される。また、傾斜板の中央部分に形成された幅広部１８では、積載物の外周側壁を支持しうる範囲が大きくなるため、直径がより大きな円筒形状の重量物をも積載することが可能となる。
【００３７】
図５はこの発明の第２の実施の形態による重量物用パレットのほぼ中央部分を示した斜視図であり、図６は図５のＶＩ−ＶＩラインから見た図である。重量物用パレットの基本的な構成は第１の実施の形態と同一であるので、ここでは相違点のみを説明する。
【００３８】
図５を参照して、支持部材１３ａ及び１３ｂの軸方向と直交する方向の、傾斜板３ａ及び３ｂ上面に、傾斜板上端部には第１の固定具２２ａ〜２２ｄが取り付けられ、傾斜板下端部には第２の固定具２５ａ〜２５ｄが取り付けられている。そして、第１の固定具２２ａ〜２２ｄと第２の固定具２５ａ〜２５ｄとに挟まれるように、傾斜板上端部から傾斜板下端部へと向かってほぼ矩形形状の移動阻止板２９ａ〜２９ｄが設置される。これら四組の第１の固定具と第２の固定具及び移動阻止板は、すべて同一の構造であるので、以降の説明では、これらの傾斜板上の配置については図５の第１の固定具２２ｄと第２の固定具２５ｄと移動阻止板２９ｄを参照して説明するものとする。
【００３９】
図５及び図６を参照して、移動阻止板２９ｄは傾斜板３ｂの軸方向と直交して上面に対してほぼ垂直に設置することができるほぼ矩形形状の平板であり、長手方向の長さは設置位置における傾斜板３ｂの幅とほぼ同じに形成されている。また、移動阻止板２９ｄの厚さＴは、傾斜板３ｂ上へ設置される側から傾斜板３ｂの垂直方向に向かうにつれて、厚みが小さくなるように形成されている。
【００４０】
第１の固定具２２ｄは、傾斜板３ｂの斜面上端部に取り付けられた第１の支持部材２３ｄと第２の支持部材２４ｄとからなる。第１の支持部材２３ｄと第２の支持部材２４ｄとは、移動阻止板２９ｄを斜面上端部から斜面下端部に向かって挿入自在に取り付けた際に、移動阻止板２９ｄの両面をそれぞれ支持できるように間隔をあけて配置されている。この間隔の大きさは、移動阻止板２９ｄの厚みに沿って、傾斜板３ｂ上面から離れるにつれて狭まるように傾斜が形成されている。
【００４１】
第２の固定具２５ｄは、傾斜板３ｂの斜面下端部に取り付けられた第１の支持部材２６ｄと第２の支持部材２８ｄとストッパー部材２７ｄとからなる。これらの第１の支持部材２６ｄと第２の支持部材２８ｄは、第１の固定具２２ｄにおける第１の支持部材２３ｄと第２の支持部材２４ｄと同様の間隔と傾斜を形成するように配置されている。ストッパー部材２７ｄは、第１の支持部材２６ｄと第２の支持部材２８ｄとの最も斜面下端側で挟まれるように位置し、第１の支持部材２６ｄと第２の支持部材２８ｄと傾斜板３ｂとに固定されている。
【００４２】
移動阻止板２９ｄを傾斜板３ｂ上に取り付ける場合は、移動阻止板２９ｄの設置される側の面を傾斜板３ｂに接しつつ、移動阻止板２９ｄの長手方向の先端部を第１の固定具２２ｄの第１の支持部材２３ｄと第２の支持部材２４ｄとの間に挿入する。移動阻止板２９ｄが傾斜板３ｂの軸方向と直交する方向に、斜面上端部から斜面下端部に向かって更に移動阻止板２９ｄを進行させ、第２の固定具２５ｄの第１の支持部材２６ｄと第２の支持部材２８ｄとの間に挿入する。更に移動阻止板２９ｄを斜面下端部に向かって進行させると、移動阻止板２９ｄの長手方向の先端部が第２の固定具２５ｄのストッパー部材２７ｄに当接し、移動阻止板２９ｄの取り付けが完了する。
【００４３】
コイル等の重量物を積載する場合は、図６に示すように、積載物の保護のために傾斜板３ｂ上に敷板３０等の緩衝材料を敷設し、その上部にコイル等を積載する。敷板３０の厚さは、第１の固定具２２ａ〜２２ｄ及び第２の固定具２５ａ〜２５ｄの高さより大きく設定されている。これにより、コイル等が第１の固定具２２ａ〜２２ｄ及び第２の固定具２５ａ〜２５ｄに直接触れることがなく、コイル等に損傷を与えない。そして、コイル等の設置には、隣接する移動阻止板２９ａ〜２９ｄとの間に木材等を挿入固定する。コイル等が輸送中にその軸方向に移動しようとした場合、移動阻止板２９ａ〜２９ｄは第１の固定具２２ａ〜２２ｄ及び第２の固定具２５ａ〜２５ｄを介して傾斜板３ａ及び３ｂの軸方向に固定されているため、木材等を介してコイル等の軸方向への移動を阻止することができる。
【００４４】
また、輸送中に重量物用パレット１が傾斜板３ａ又は３ｂと垂直な方向に振動した場合でも、第１の固定具２２ａ〜２２ｄ及び第２の固定具２５ａ〜２５ｄに形成された間隔の上部の幅Ｗは、移動阻止板２９ａ〜２９ｄの設置される側の厚さＴより小さいため、移動阻止板２９ａ〜２９ｄが傾斜板３ａ又は３ｂの垂直な方向へと脱離することが防止される。また、移動阻止板２９ａ〜２９ｄには常に、傾斜板３ａ及び３ｂに対して下部方向に重力が加わっているため、傾斜板３ａ又は３ｂに沿って抜け出るおそれもない。
【００４５】
図７は、この発明の第２の実施の形態における移動阻止板の他の例を示した図であって、図６に対応する図である。移動阻止板３１の形状が図６の移動阻止板２９ｄと相違するのみで、他の部分はすべて同一である。
【００４６】
図を参照して、移動阻止板３１は厚さがほぼ均一な矩形状の平板により構成され、傾斜板３ｂへの設置側の端部に突起部材３２ａ及び３２ｂがそれぞれ取り付けられている。第１の固定具２２ｄにおける第１の支持部材２３ｄと第２の支持部材２４ｄとの間の間隔は、傾斜板３ｂの上面から垂直な方向に向かって狭まるように形成されており、その上部における最も幅の狭い部分の幅Ｗは、移動阻止板３１と突起部材３２ａ及び３２ｂの厚さの合計Ｔより小さくなるように形成されている。第２の固定具２５ｄにおける第１の支持部材２６ｄと第２の支持部材２８ｄとの間隔も、これと同様に形成されている。
【００４７】
移動阻止板３１を同様の方法で取り付けた後は、重量物用パレット１が傾斜板３ｂと垂直な方向に振動しても、第１の固定具２２ｄ及び第２の固定具２５ｄに形成された間隔の上部の幅Ｗは、移動阻止板３１と突起部材３２ａ及び３２ｂの厚さの合計Ｔより小さいため、移動阻止板３１の傾斜板３ｂとの垂直な方向への脱離が防止される。
【００４８】
図８は、この発明の第３の実施の形態による重量物用パレットの支持部材の一部破断斜視図であって、支持部材に対して移動阻止手段が係合する前後の状態を各々示した図である。支持部材の基本的な構造は第１の実施の形態と同一であるので、ここでは相違点のみを説明する。また、ここでは一方の支持部材１３ａに対する移動阻止手段の取り付けのみ説明する。
【００４９】
図８の（１）に示すように、支持部材１３ａにおいては、第１のリブ板６の幅が支持板４ａの外面から傾斜板３ａの端部にまで及び、第２のリブ板１９の幅が支持板４ａの内面から傾斜板３ａの端部にまで及ぶ点が異なっている。
【００５０】
また、移動阻止部材３５と固定部材４０とからなる移動阻止手段を備えている点が異なっている。
【００５１】
移動阻止部材３５は、移動阻止板３６と一対の係止板３７ａ及び３７ｂとから構成される。移動阻止板３６は傾斜板３ａの軸方向と直交して上面に対してほぼ垂直に設置することができるほぼ矩形形状の平板であり、長手方向の長さは設置位置における傾斜板３ａの幅よりやや長く形成されている。移動阻止板３６の長手方向の一方の端部には、後述する固定部材４０のピン４３と係合しうる切欠溝３８が形成されている。移動阻止板３６の長手方向の他方の端部には、一対の係止板３７ａ及び３７ｂが移動阻止板３６を挟むように取り付けられている。係止板３７ａと３７ｂとの間隔は、第２のリブ板１９を挿入できる間隔に形成されている。また、係止板３７ａ及び３７ｂには、移動阻止板３６の設置される側の長辺と係止板３７ａ及び３７ｂとの間に、傾斜板３ａの斜面下端部分を挿入可能な幅のスペース３４を形成できるように、突出部３９ａ及び３９ｂが形成されている。
【００５２】
一方、固定部材４０は一対の係止板４１ａ及び４１ｂと、所定の間隔をあけてこれらの係止板４１ａ及び４１ｂを連結する連結板４２と、係止板４１ａ及び４１ｂとの間隔に取り付けられ移動阻止板３６の切欠溝３８と係合し得るピン４３とからなる。係止板４１ａと４１ｂとの間隔は、第１のリブ板６が挿入できる間隔に形成されている。また、係止板４１ａ及び４１ｂの形状は、固定部材４０が移動阻止部材３５に取り付けられた際に、移動阻止板３６の設置される側の長辺と係止板４１ａ及び４１ｂとの間に傾斜板３ａの斜面上端部を挿入可能な幅のスペース４５を形成できるように、係止板４１ａ及び４１ｂには突出部４４ａ及び４４ｂが形成されている。
【００５３】
ここで、移動阻止部材３５と固定部材４０とを傾斜板３ａ上に設置する方法について説明する。まず、移動阻止部材３５は、移動阻止板３６の設置側の長辺を傾斜板３ａに接するようにし、係止板３７ａ及び３７ｂが傾斜板３ａの斜面下端部側に位置するように配置する。そして、係止板３７ａ及び３７ｂの突出部３９ａ及び３９ｂと移動阻止板３６との間のスペース３４に傾斜板３ａの斜面下端部が位置し、且つ、係止板３７ａと３７ｂとの間隔に第２のリブ板１９が位置するように、移動阻止部材３５を傾斜板３ａの上方に向かって少し移動させて取り付ける。
【００５４】
次に、固定部材４０のピン４３を移動阻止部材３５の切欠溝３８の入り口に係合させる。そして、係止板４１ａ及び４１ｂの突出部４４ａ及び４４ｂと移動阻止板３６との間のスペース４５に傾斜板３ａの斜面上端部が位置し、且つ、係止板４１ａと４１ｂとの間隔に第２のリブ板１９と同一面内の第１のリブ板６が位置するように切欠溝３８に沿ってピン４３を更に進行させて完全に係合させる。
【００５５】
図８の（２）に示すように、移動阻止板３６の切欠溝３８と固定部材４０のピン４３とが完全に係合した状態では、第１のリブ板６と第２のリブ板１９のそれぞれを一対の係止板３７ａ及び３７ｂと、一対の係止板４１ａ及び４１ｂで挟み込んでいるため、移動阻止板３６が支持部材１３ａの軸方向に対して固定される。
【００５６】
また、傾斜板３ａ及び３ｂの斜面上端部と斜面下端部との二点において、それぞれの係止板の突出部と移動阻止板との間のスペース３４とスペース４５とで挟み込んでいるため、重量物用パレット１が傾斜板３ａ又は３ｂと垂直な方向に振動しても、移動阻止板３６の傾斜板３ａ又は３ｂとの垂直な方向への脱離が防止される。更に、移動阻止部材３５及び固定部材４０は、傾斜板３ａ及び３ｂをその軸と直交する方向の両側から挟み込むように取り付けられているので、傾斜板３ａ又は３ｂに沿った方向の振動に対しても移動阻止板３６の設置状態が安定する。
【００５７】
移動阻止部材３５と固定部材４０とからなる移動阻止手段は、同一の構成の支持部材１３ｂにも当然に取り付けが可能である。したがって、支持部材１３ａ及び１３ｂや、傾斜板３ａ及び３ｂに特別な加工を施すことなく、移動阻止板を取り付けることが可能になる。
【００５８】
尚、上記の各実施の形態においては、支持部材１３の断面構造は図３に示した形状であるが、支持部材１３全体の荷重をすべて外枠部材２のみに伝達できる構造であれば、支持部材１３の断面構造は他の形状でも良い。
【００５９】
また、上記の第３の実施の形態においては、移動阻止手段を取り付けるために、第１のリブ板と第２のリブ板とは同一面内にある必要があるが、他の実施の形態では、このような制約は必ずしも必要ではない。
【００６０】
更に、上記の各実施の形態においては、一対の支持部材の各々は互いに対称な形状であるが、このような制約は必ずしも必要ではなく、非対称に形成されていても良い。
【００６１】

And a bottom plate 5a positioned below the inclined plate 3a and arranged horizontally, and vertically arranged so as to bridge substantially the center of the lower surface of the inclined plate 3a and substantially the center of the upper surface of the bottom plate 5a, and are welded and joined to each other. And a plate 4a. In the inclined plate 3a, a wide portion 18a is formed so as to be wider than other portions in a certain range from substantially the center in the axial direction. Further, the support member 13a is attached in a direction orthogonal to the axial direction thereof, and includes first rib plates 6a to 6k and second rib plates 19a to 19k attached at predetermined intervals. The edges of the first rib plates 6a to 6k are welded to the outer lower surface of the inclined plate 3a, the outer surface of the support plate 4a, and the outer upper surface of the bottom plate 5a. The edges of the second rib plates 19a to 19k are welded to the inner lower surface of the inclined plate 3a, the inner surface of the support plate 4a, and the inner upper surface of the bottom plate 5a. In addition, the first rib plate 6 and the second rib plate 19 are arranged in the same number and are included in the same plane.
[0031]
The support member 13b also includes an inclined plate 3b, a support plate 4b, a bottom plate 5b, first rib plates 7a to 7k, and second rib plates 20a to 20k, and the support member 13a is parallel to the axial direction thereof. It has a symmetrical shape about a major axis.
[0032]
The outer frame members 2a and 2b are made of an H-shaped steel or an I-shaped steel arranged in parallel with each other, and are arranged so that two parallel surfaces of each H-shaped steel or the like become horizontal.
[0033]
The ends of the support members 13a and 13b are inserted into the outer frame members 2a and 2b, and are joined to the vertical surfaces of the outer frame members 2a and 2b. That is, both ends of each of the inclined plates 3a and 3b, both ends of each of the support plates 4a and 4b, and both ends of each of the bottom plates 5a and 5b are directly joined to the outer frame members 2a and 2b. .
[0034]
Since both ends of each of the support members 13a and 13b are supported only by the outer frame members 2a and 2b, when a heavy object such as the coil 11 is loaded on the inclined plates 3a and 3b, the inclined plates 3a and 3b All the loads are transmitted to the outer frame members 2a and 2b while distributing the load on the outer frame members 13a and 13b.

Further, corner fittings 8a to 8d for supporting the outer frame members 2a and 2b are attached to lower portions of both ends of each of the outer frame members 2a and 2b, and a load applied to the outer frame members 2a and 2b is Eventually, all will be transmitted to the corner fittings 8a to 8d. Therefore, since the load is supported only by the corner fittings 8a to 8d at the four corners, the heavy goods pallet 1 can be mounted on the tank container-dedicated semi-trailer.
[0036]
Here, the use state of the heavy goods pallet 1 will be described. Referring to FIG. 3, when the coil 11 is loaded, the outer peripheral side wall portion is supported by the pair of inclined plates 3a and 3b, and rolling in the direction orthogonal to the axis of the coil 11 is prevented. Further, in the wide portion 18 formed at the center portion of the inclined plate, the range in which the outer peripheral side wall of the load can be supported is increased, so that a cylindrical heavy object having a larger diameter can be loaded.
[0037]
FIG. 5 is a perspective view showing a substantially central portion of a heavy goods pallet according to a second embodiment of the present invention, and FIG. 6 is a view seen from a line VI-VI in FIG. Since the basic structure of the heavy goods pallet is the same as that of the first embodiment, only the differences will be described here.
[0038]
Referring to FIG. 5, first fixtures 22a to 22d are attached to the upper ends of the inclined plates 3a and 3b in the direction orthogonal to the axial direction of the support members 13a and 13b, and the lower ends of the inclined plates are attached. Second fixtures 25a to 25d are attached to the part. Then, substantially rectangular-shaped movement prevention plates 29a to 29d are provided from the upper end of the inclined plate toward the lower end of the inclined plate so as to be sandwiched between the first fixtures 22a to 22d and the second fixtures 25a to 25d. Will be installed. Since the four sets of the first fixing tool, the second fixing tool, and the movement preventing plate are all of the same structure, in the following description, the arrangement on these inclined plates will be described with reference to the first fixing tool shown in FIG. The description will be made with reference to the fixture 22d, the second fixture 25d, and the movement preventing plate 29d.
[0039]
Referring to FIGS. 5 and 6, the movement preventing plate 29d is a substantially rectangular flat plate that can be installed substantially perpendicular to the axial direction of the inclined plate 3b and perpendicular to the upper surface, and has a length in the longitudinal direction. Is formed to be almost the same as the width of the inclined plate 3b at the installation position. Further, the thickness T of the movement preventing plate 29d is formed so that the thickness becomes smaller as going from the side on the inclined plate 3b to the vertical direction of the inclined plate 3b.
[0040]
The first fixture 22d includes a first support member 23d and a second support member 24d attached to the upper end of the slope of the inclined plate 3b. The first support member 23d and the second support member 24d can support both surfaces of the movement prevention plate 29d when the movement prevention plate 29d is inserted from the upper end of the slope toward the lower end of the slope. Are spaced apart from each other. The size of the interval is formed so as to be narrower along the thickness of the movement preventing plate 29d as the distance from the upper surface of the inclined plate 3b decreases.
[0041]
The second fixture 25d includes a first support member 26d, a second support member 28d, and a stopper member 27d attached to the lower end of the inclined surface of the inclined plate 3b. The first support member 26d and the second support member 28d are arranged so as to form the same interval and inclination as those of the first support member 23d and the second support member 24d in the first fixture 22d. ing. The stopper member 27d is positioned so as to be sandwiched at the lowermost end of the slope between the first support member 26d and the second support member 28d, and the first support member 26d, the second support member 28d, the inclined plate 3b, Fixed to.
[0042]
When the movement preventing plate 29d is mounted on the inclined plate 3b, the longitudinal end of the movement preventing plate 29d is attached to the first fixture 22d while the surface on the side where the movement preventing plate 29d is installed is in contact with the inclined plate 3b. Between the first support member 23d and the second support member 24d. The movement prevention plate 29d further advances the movement prevention plate 29d from the upper end of the slope toward the lower end of the slope in a direction orthogonal to the axial direction of the inclined plate 3b, and the first support member 26d of the second fixture 25d and It is inserted between the second support member 28d. When the movement prevention plate 29d is further advanced toward the lower end of the slope, the longitudinal end of the movement prevention plate 29d abuts against the stopper member 27d of the second fixture 25d, and the mounting of the movement prevention plate 29d is completed. .
[0043]
In the case of loading a heavy object such as a coil, as shown in FIG. 6, a cushioning material such as a floor plate 30 is laid on the inclined plate 3b for protection of the load, and the coil and the like are mounted thereon. The thickness of the floor plate 30 is set to be larger than the heights of the first fixtures 22a to 22d and the second fixtures 25a to 25d. Thus, the coils and the like do not directly touch the first fixtures 22a to 22d and the second fixtures 25a to 25d, and do not damage the coils and the like. For installation of the coil or the like, wood or the like is inserted and fixed between the adjacent movement preventing plates 29a to 29d. When the coil or the like attempts to move in the axial direction during transportation, the movement preventing plates 29a to 29d are connected to the axes of the inclined plates 3a and 3b via the first fixtures 22a to 22d and the second fixtures 25a to 25d. Since it is fixed in the direction, the movement of the coil and the like in the axial direction through the wood and the like can be prevented.
[0044]
In addition, even if the heavy goods pallet 1 vibrates in a direction perpendicular to the inclined plate 3a or 3b during transportation, the upper part of the gap formed on the first fixtures 22a to 22d and the second fixtures 25a to 25d. Is smaller than the thickness T on the side where the movement preventing plates 29a to 29d are installed, so that the movement preventing plates 29a to 29d are prevented from detaching in the direction perpendicular to the inclined plate 3a or 3b. . In addition, since gravity is always applied to the movement preventing plates 29a to 29d in the lower direction with respect to the inclined plates 3a and 3b, there is no possibility that the movement preventing plates 29a to 29d will fall out along the inclined plates 3a or 3b.
[0045]
FIG. 7 is a diagram showing another example of the movement preventing plate according to the second embodiment of the present invention, and is a diagram corresponding to FIG. Only the shape of the movement prevention plate 31 is different from that of the movement prevention plate 29d in FIG. 6, and all other parts are the same.
[0046]
Referring to the figure, movement prevention plate 31 is formed of a rectangular flat plate having a substantially uniform thickness, and projection members 32a and 32b are attached to ends on the installation side of inclined plate 3b, respectively. The space between the first support member 23d and the second support member 24d in the first fixture 22d is formed so as to narrow in the vertical direction from the upper surface of the inclined plate 3b. The width W of the narrowest portion is formed to be smaller than the total thickness T of the movement preventing plate 31 and the projection members 32a and 32b. The distance between the first support member 26d and the second support member 28d in the second fixture 25d is formed in the same manner.
[0047]
After the movement prevention plate 31 is attached in the same manner, even if the heavy goods pallet 1 vibrates in the direction perpendicular to the inclined plate 3b, it is formed on the first fixture 22d and the second fixture 25d. Since the width W of the upper part of the interval is smaller than the sum T of the thicknesses of the movement preventing plate 31 and the projection members 32a and 32b, the movement preventing plate 31 is prevented from separating from the inclined plate 3b in the vertical direction.
[0048]
FIG. 8 is a partially cutaway perspective view of a support member of a heavy goods pallet according to a third embodiment of the present invention, showing a state before and after a movement preventing means is engaged with the support member. FIG. Since the basic structure of the support member is the same as that of the first embodiment, only the differences will be described here. Here, only the attachment of the movement preventing means to one of the support members 13a will be described.
[0049]
As shown in FIG. 8A, in the support member 13a, the width of the first rib plate 6 extends from the outer surface of the support plate 4a to the end of the inclined plate 3a, and the width of the second rib plate 19 Differs from the inner surface of the support plate 4a to the end of the inclined plate 3a.

The movement preventing plate 36 is a substantially rectangular flat plate that can be installed substantially perpendicularly to the upper surface perpendicular to the axial direction of the inclined plate 3a, and the length in the longitudinal direction is larger than the width of the inclined plate 3a at the installation position. It is formed slightly longer. At one end of the movement preventing plate 36 in the longitudinal direction, a notch groove 38 that can be engaged with a pin 43 of a fixing member 40 described later is formed. A pair of locking plates 37 a and 37 b are attached to the other end of the movement preventing plate 36 in the longitudinal direction so as to sandwich the movement preventing plate 36. The space between the locking plates 37a and 37b is formed such that the second rib plate 19 can be inserted. The locking plates 37a and 37b have a space 34 between the long side on which the movement preventing plate 36 is installed and the locking plates 37a and 37b, and having a width capable of inserting the lower end of the slope of the inclined plate 3a. The projections 39a and 39b are formed so as to be able to be formed.
[0052]
On the other hand, the fixing member 40 is attached to a pair of locking plates 41a and 41b, a connecting plate 42 connecting the locking plates 41a and 41b at a predetermined interval, and an interval between the locking plates 41a and 41b. It comprises a pin 43 which can be engaged with the notch groove 38 of the movement preventing plate 36. The space between the locking plates 41a and 41b is formed such that the first rib plate 6 can be inserted. The shape of the locking plates 41a and 41b is such that, when the fixing member 40 is attached to the movement preventing member 35, the long side on the side where the movement preventing plate 36 is installed and the locking plates 41a and 41b are provided. Protrusions 44a and 44b are formed on the locking plates 41a and 41b so that a space 45 having a width capable of inserting the upper end of the inclined surface of the inclined plate 3a can be formed.
[0053]
Here, a method of installing the movement preventing member 35 and the fixing member 40 on the inclined plate 3a will be described. First, the movement preventing member 35 is arranged such that the long side on the installation side of the movement preventing plate 36 is in contact with the inclined plate 3a, and the locking plates 37a and 37b are located on the lower end side of the inclined surface of the inclined plate 3a. The lower end of the slope 3a is located in the space 34 between the protrusions 39a and 39b of the locking plates 37a and 37b and the movement preventing plate 36, and the space between the locking plates 37a and 37b The movement preventing member 35 is attached by slightly moving the upper part of the inclined plate 3a so that the second rib plate 19 is located.
