Description

【0001】
【発明の属する技術分野】
本発明は、天井高が低い室内等で、高さの比較的高い重量物を吊って移動させることを可能にした簡便な揚荷装置に関する。
【0002】
【従来の技術】
従来は、低天井かつ狭い室内等で、高さの比較的高い配電盤の如き重量のある機器の搬入据え付けは、多人数による手作業によっており、安全性の向上、作業時間の短縮、作業員の削減が課題となっていた。
特に配電盤、継電器盤などは重心が高く、比較的幅の狭い重量物の立て起こし及び移動には、従来の荷役機械や装置が使用できないため、必要以上の人員を配置して手作業により万全の態勢で対処していたものであり、特にベース、基礎上への据え付けには、アンカーボルト等の突起をかわすために一層困難をきわめていた。
【0003】
従来の簡易型の揚荷装置として、I形鋼の両端をキャスター付の脚で支えて門形にしたものに、I形鋼に沿って移動するトロリー付チェンブロックを吊り下げたものが一般的に使用されていたが、本願が目的としている吊り代の少ない場合は、チェンブロックを使用するスペースが無いため使用不能であった。
【0004】
【発明が解決しようとする課題】
例えば、天井高が2.7mの配電室に、盤高2.35mの配電盤を設置しようとするとき、吊り代は0.35mしか無いので、この0.35m以下の吊り代で、自重350Kg程度の重量物を吊ることのできる、コンパクトな揚荷装置の開発が要望されていた。
【0005】
【課題を解決するための手段】
上記の問題点を解決するために、本発明は、ウインチのワイヤーロープを、平行する2本のワイヤロープに連結ビームを介して連結して、この2分割ワイヤロープが滑車を経て吊りビームに連結され、この吊りビームに機器を吊る構造としたことにより、吊り代をチェンブロックを使用する従来の装置よりも大幅に短縮して、上記の課題を解決することができる。
【0006】
【発明の実施の形態】
本発明は、下端にキャスターを備えた台枠上に、適宜位置にウインチ設置し、かつ前端下部に第2滑車を取付けた枠形支柱を、着脱可能に立設したウインチ架台と、下端にキャスターを取付けた4本の支柱を、長方形の4つ角に直立させて、その上端を着脱可能な上端枠により固定し、下端近くを着脱可能な横桟により補強した分解可能な吊り架台を、上記ウインチ架台の前方に配置している。
【0007】
上記吊り架台の上端枠上に、所定間隔をもって平行する一対の細長い滑車取付バーの後端を直交方向に連結した滑車支持アームを、後端を上記ウインチ架台側に突出させて前後方向に長く着脱可能に取付け、この滑車支持アームの平行な2本の滑車取付バーに、それぞれ左右に所定間隔を保って相対向する2個づつの第1滑車を回転自在に取付け、その後端連結部に第3滑車を吊設して、この第3滑車付近を上記ウインチ架台の上端に当接させている。
【0008】
さらに2個づつの上記第1滑車にそれぞれ懸かって、両端が垂れ下がった2本の平行ワイヤロープの、反ウインチ架台側の一端に、吊り具を備えた横長な吊りビームを連結するとともに、他端に連結ビームを連結し、この連結ビームの中央部に、上記ウインチから上記第3滑車と第2滑車を経て延びるウインチワイヤロープの先端を連結したものである。
【0009】
また、別の例として、上記吊り架台の上端枠の下側の幅方向の中央部に、I形鋼からなるランウエイレールを前後に長く着脱可能に取付け、このランウエイレールに沿って移動するプレンサドルを装着し、このプレンサドルに、上記ランウエイレールと直交する方向の両側に張り出した滑車支持アーム取付座を設けて、この滑車支持アーム取付座に、上記滑車支持アームを、一対の滑車支持バーが上記ランウエイレールの両側のI形鋼の梁背丈内に平行し、かつ一端を上記ウインチ架台側に突出させて取付けて、この滑車支持アームに取り付けた第1滑車に懸っているワイヤロープにより吊り上げた重量物を、ランウエイレールに沿ってプレンサドルを移動させることにより移動可能としたものである。
【0010】
また、吊り上げた重量物の下端を、重量物を吊った状態で移動する場合の安定支持のために、平鋼材または棒状材を倒立門形に屈折形成した底受部材を、上記支持架台の横桟に係合着脱可能に設ける場合もある。
【0011】
また、吊り上げた重量物を移動可能にするランウエイレールとプレンサドルを持つ揚荷装置において、吊り荷台の下端近くを補強するための、ランウエイレールと直交する方向の横桟を、吊り上げた機器の移動範囲を拡げるために、コ字形に形成して外方に張り出させる場合もある。

【0018】
図1は重量物Wを吊り上げた状態を示しており、この状態で吊り架台20とともに移動しようとする場合の、重量物Wの揺動を防止する目的で重量物Wの下端を支持するための、平鋼により倒立門形に形成し、両端の直立部の上端を外側に折り曲げて横桟26に係合する係合部41を形成した2個の底受け部材40を設ける場合もある。
なお、横臥している重量物Wを立て起こすことも可能である。
【0019】
(第2実施例)
図4、図5、図6に示す第2実施例は、吊り架台20において、吊り揚げた重量物Wを吊ったままで前後方向に移動させることを可能にしたもので、ウインチ架台10と吊り架台20及び滑車支持アーム30の構成は第1実施例と全く同様であり、詳細説明を省略する。
【0020】
吊り架台20の上端枠24の下側の幅方向の中央に、I形鋼からなるランウエイレール50が前後方向に長く、吊り架台20より突出して取付けられる。
その取付けは、ランウエイレール50の上辺に、上端枠24の前後辺に係合する鍵形に折れ曲がった係合金具51が2か所に溶接してあって、この係合金具51,51が上端枠24の前後辺にそれぞれ係合し、上下方向の止め孔に止ピン52を挿して止めてある。
【0021】
このランウエイレール50には、走行のための4個の転輪を持つプレンサドル53が装着され、このプレンサドル53の下側に、ランウエイレール50と直交する方向の両側に張り出した2本の滑車支持アーム取付座54を設け、この滑車支持アーム取付座54上に、第1実施例と同様の第1滑車34,34aを備えている滑車支持アーム30を載せて、押さえ板55により取付けている。
【0022】
この滑車支持アーム30には、第1実施例と同様に、第1滑車34,34aに、図7に示す如く平行ワイヤロープ39,39がそれぞれに懸けられ、前部の第1滑車34,34から垂下した一端に、横長な吊りビーム37を連結し、この吊りビーム37の下辺に吊り具37aを取付け、さらに後部の第1滑車34a,34aから垂下した平行ワイヤロープ39,39の端部に横長な連結ビーム38を連結し、この連結ビーム38の下辺中央部に、ウインチ架台10に設置されているウインチ15から延びるウインチワイヤロープ15aが、滑車支持アーム30の後端に取付けてある第3滑車35と、ウインチ架台10の前側下部に取付けられている第2滑車13に懸回して連結されている。

こうして吊り上げられた重量物Wは、吊り架台20は停止したままで、ランウエイレール50に沿って滑車支持アーム30と一体になっているプレンサドル53を、ウインチ架台10とともに前後方向に移動させることにより、重量物Wを前後方向に移動させることができる。
【0024】
この重量物Wを前後方向に移動させるとき、吊り架台20の下端部を補強している横桟26と干渉して、吊り架台20の4本の支柱23に囲まれた範囲に限定されないように拡げる目的で、前後の横桟を、図9に示す如くコ字形に形成した拡張横桟26aとして、前後に張り出させて移動範囲を拡張する場合がある。
【0025】
こうして吊り上げた重量物Wの移動範囲を大きく拡げたいとき、ランウエイレール50を長尺物として吊り架台20より大きく張り出させる場合があり、この場合ランウエイレール50の延長端を支持する別の門形支持部材を設け、かつ移動方向の横桟26を取り外すものであるが、図示を省略する。
