Description

【0001】
【産業上の利用分野】
本発明は狭隘作業空間での配管の移動を可能とした配管支持装置に関する。
【0002】
【従来の技術】
従来の配管支持装置の1例を図6に示す。
図において配管20を懸垂する荷重伝達ロッド50により配管20の支持荷重はその上端において外箱40内上部に配設された荷重伝達板60に伝達される。
【0003】
荷重伝達板60に伝達された荷重は、さらに該荷重伝達板60の下面に接触するコイル状バネ70に伝わり、該バネ70により荷重を支持される。コイル状バネ70も外箱40内に装着されている。
【0004】
そしてバネ70の弾発力に抗した配管20の荷重により配管20の鉛直方向の移動は、該バネの伸縮により追従できるよう構成している。
【0005】
【発明が解決しようとする課題】
ところで前述のような従来の配管支持装置は、配管の鉛直方向の移動が大きい場合、コイル状バネの伸縮量を大きくする為にコイル状バネの長さが長くなり、それに伴ないコイル状バネを収納する外箱の長さを長くする必要があるため装置本体が長くなることから狭隘な作業空間には適用できないという不具合があった。
【0006】
本発明は上記不具合点を解消し、狭隘部であっても配管の移動に追従できる新たな配管支持装置を得ることを目的としている。
【0007】
【課題を解決するための手段】
前記目的を達成するための構成として本発明のゼンマイバネ式配管支持装置は、分割された上下外箱をボルト結合して一体に構成した外箱内における上箱の中央部内側に設けた中心軸受と、外箱内に設けた中心軸支持板の中央部上面に突設した中心軸受との間に亘り鉛直方向に中心軸を垂設し、該中心軸に、回転自在に回転体を嵌挿し、該回転体の内部にゼンマイ状に回巻したバネ板を収納し、該バネ板の一端を前記中心軸支持板に穿設したスリットに挿入固定し、バネ板他端を回転体に穿設したスリットに挿入固定するとともに、前記回転体の外周に荷重伝達用ワイヤーを回巻し、その一端を回転体外周に固定すると共に、ワイヤー他端を下箱中央部に穿設したワイヤー穴を介して垂下させて配管に取付け可能に構成したことを特徴としている。
【0008】
【作用】
上記構成よりなる本発明においては、配管の鉛直方向の移動は、該配管を懸架した荷重伝達ワイヤーを介して外箱内部に装架した回転体に回転方向の移動として変換される。
【0009】
これにより回転体内部に取付けられたゼンマイ状バネ板が配管の移動量に伴ない巻き締められることによりスプリング効果を発生し配管の荷重を支持し、かつ配管の鉛直方向の移動に追従できる。
【0010】
このように配管の鉛直方向への移動を、回転体により回転方向への移動に変換することにより配管の鉛直方向への移動量が大きくても、装置本体の長さを大きくする必要がない。従って狭隘な作業空間においても配管の支持を有効に行なうことができる。
【0011】
【実施例】
以下図面により本発明の一実施例について説明する。
図1は本発明の実施例に係る配管支持装置の縦断面図、図2は上外箱を示し(a)は側断面図、(b)は平面図、図3は中心軸支持板を示し(a)は側断面図、(b)は平面図、図4は下外箱を示し(a)は側断面図、(b)は平面図、図5は回転体とその構成部品を示し(a)は回転体側断面図、(b)は平面図、(c)はバネ板の側面及び平面図、(d)はワイヤーの斜視図である。
【0012】
これらの図において、1は上外箱、2は下外箱で両外箱を各外箱に穿設したボルト穴14に挿入するボルト15により一体的に取付けられ配管支持装置本体を形成している。
【0013】
そして該配管支持装置本体内には、中心軸支持板3が本体内部空間内に配設され、その両端は前記ボルト15により上下各外箱と一体的に接続固着されている。
【0014】
上外箱1の中央部にはその下面に中心軸受9が垂設されると共に、これと対向する中心軸支持板3の中央部位置にはその上面に同様に中心軸受9′が突設され、両中心軸受9,9′に亘り中心軸7が鉛直方向に垂設嵌挿されている。また上外箱1の上面には中央部付近左右に本体取付用ラグ10がそれぞれ固着され、外箱本体を所要位置に保持支承している。
【0015】
中心軸7には回転体4が回転可能に嵌挿され、該回転体4の外周にはワイヤー巻き付け溝13が形成され、該溝13中に配管荷重伝達用ワイヤー6が巻き付けられている。
【0016】
また回転体4内部には帯状のバネ板5がゼンマイ状に回巻して収納され、該バネ板5の一端18は中心軸支持板3に穿設したスリット11に巻込み固定されると共に、バネ板5の他端19は、回転体4に穿設したスリット12に巻込み固定される。
【0017】
荷重伝達用ワイヤー6は一端に回転子固定用ボルト穴21を有し、該穴21にボルトを挿入することにより回転体4にワイヤーの一端は固着され、ワイヤー他端は中心軸支持板3の一側近くに穿設したワイヤー穴16を通して滑車8を介して下外箱2の中心部に穿設したワイヤー穴17より垂下させ、その垂下したワイヤー端は配管20に固着されて同配管20を懸架支持している。
【0018】
前記滑車8は中心軸支持板3の下面に複数個垂設された支持手段に回転自在に軸架されており、ワイヤー6を下外箱2の中央部に設けたワイヤー穴17に導くためのものである。
【0019】
つぎに上記構成よりなる配管支持装置の作動について説明する。
配管支持装置に配管荷重を作用させると、ワイヤー6を介して荷重は同ワイヤーの一端に固着した回転体4に伝達され、回転体内部のゼンマイ状に収納されたバネ板5のスプリング作用により配管20の荷重を支持し、かつ配管の鉛直方向の移動に追従する。
【0020】
このようにして配管の鉛直方向の移動を回転体4により回転方向への移動に変換することができるので、配管の鉛直方向の移動が大きくても、装置本体は大きくならない。
【0021】
従って狭隘部にある鉛直方向の移動量が大きい配管を支持する場合に有効である。
【0022】
以上本発明の1実施例について説明したが、本発明は上記実施例に限定されるものでなく、本発明技術思想の範囲内において種々設計変更が可能であり、それらは何れも本発明の技術的範囲に属する。
【0023】
【発明の効果】
本発明によれば、配管の鉛直方向への移動を、装置内に収納した回転体により回転方向への移動に変換することにより、配管の荷重による鉛直方向への移動量が大きくても装置本体の長さを大きくする必要がなく狭隘な作業空間においても配管を有効に支持することができる。
