Description

【0001】
【発明の属する技術分野】
この発明は、主索に吊持された吊り枠に多数の重り片が積載されたエレベーターのつり合おもりに関する。
【0002】
【従来の技術】
図6及び図7は、従来のエレベーターのつり合おもりを示す図で、図6は正面図、図7は図6の縦断側面図である。図において、1は鋼材が組立てられてなる吊り枠で、上枠2、下枠3、側枠4、側枠4の長手中間に設けられた上横枠5及び上横枠5の下側に設けられた下横枠6によって構成されている。7は吊り枠1に形成された積載室で、上枠2、側枠4、及び上横枠5に囲まれた空間によって形成されている。
【0003】
8は重り片で、複数個が互いに重合して平積みされて積載室7に積載されている。9は上枠2に挿通されて係止されたエレベーター主索の引き止め具、10は吊り枠1の図6における四隅にそれぞれ装着されたガイドシュー、11は重り押さえ具で、側枠4に設けられて積載されて最上位置に配置された重り片8を押さえて上方向変位を阻止する。12は切欠部で、側枠4に設けられて吊り枠1内側に開口し上枠2寄りに配置されている。13は下横枠6に係止されて吊下された釣合いロープである。
【0004】
従来のエレベーターのつり合おもりは上記のように構成され、重り片8の長手の一側が切欠部12を介して図6に鎖線で示すように傾斜した状態で積載室7内に搬入され、次いで水平姿勢に配置される。そして、所要の質量に対応した個数の重り片8が積載室7に平積み状態に積載される。
【0005】
【発明が解決しようとする課題】
上記のような従来のエレベーターのつり合おもりでは、重り片8が傾斜した姿勢で積載室7に搬入されるため、吊り枠1に積載された重り片8と上枠2下面との間に、搬入のためのスペースを考慮する必要がある。また、上枠2に係止された引き止め具9は主索の伸びを調整するために、下端がさらに下降するので最上位置の重り片8との間に伸び調整余裕のスペースが必要になる。
【0006】
また、釣合いロープ13においても伸びを調整するために、下横枠6と上横枠5の間に伸び調整余裕のスペースが必要になる。これらの要因によって所要の質量に対応した個数の重り片8を積載するための重り片8の自体の積み重ね高さに対して吊り枠1の背丈が増す。このため、つり合おもりの通常時の最上昇位置に対するエレベーターの昇降路の上端位置が上昇するので、昇降路の全高が増し建築費が嵩むという問題点があった。
【0007】
この発明は、かかる問題点を解消するためになされたものであり、所要の質量に対応した個数の重り片を背丈の低い吊り枠に積載することができるエレベーターのつり合おもりを得ることを目的とする。
【0008】
【課題を解決するための手段】
この発明に係るエレベーターのつり合おもりにおいては、外側面に開口部を有し、鉛直方向に並んだ複数の積載室が設けられた吊り枠と、最上段の積載室内中央で、上方から吊り枠の上枠に挿通された主索に設けられ、下方から上枠に係止された引止め具と、水平投影面において引止め具と重合しない位置で、開口部を介して最上段の積載室両側に水平方向に着脱自在に設けられ、板面が鉛直に配置された複数枚が互いに鉛直投影面において重合された第1重り片と、水平投影面において引止め具と重合しない位置で、開口部を介して最上段以外の積載室両側に水平方向に着脱自在に設けられ、板面が鉛直に配置された複数枚が互いに鉛直投影面において重合された第2重り片と、水平投影面において引止め具と重合する位置で、開口部を介して最上段以外の積載室中央に水平方向に着脱自在に設けられ、板面が鉛直に配置された複数枚が互いに鉛直投影面において重合された第3重り片とが設けられる。
【0009】
また、この発明に係るエレベーターのつり合おもりにおいては、積載室の縁部と積載室に積載された重り片とを締結する締結具が設けられる。
【0010】
【発明の実施の形態】
実施の形態1.
図1〜図3は、この発明の実施の形態の一例を示す図で、図1は正面図、図2は図1の縦断側面図、図3は図2の要部拡大図である。図において、14は鋼材が組立てられてなる吊り枠で、側枠15並びにそれぞれ横断面が逆U字形をなす上枠16、下枠17、側枠15の長手中間に設けられた上横枠18及び上横枠18の下側に設けられた下横枠19によって構成されている。
【0011】
20は積載室で、両側の側枠15に囲まれて、上枠16と上横枠18の間、上横枠18と下横枠19の間及び下横枠19と下枠17の間にそれぞれ形成されて吊り枠14の外面に開口し、例えば上横枠18の上面によって下面が形成され、また上枠16の下端によって上縁部が構成されると共に、上枠16の逆U字形部によって上縁部よりも上方に引退した凹所21が構成されている。
【0012】
22は重り片で、方形の板状材からなり板面が鉛直に配置され複数枚が互いに重合されて、それぞれの積載室20に積載されている。そして、それぞれの重り片22は吊り枠14の外面から上端部が積載室20の凹所21に挿入され、次いで下端部が積載室20の下面に送り込まれて積載室20に積載される。23は上側ボルトで、上横枠18等の一方の逆U字側壁の外側から挿入されて重合された重り片22の上縁部及び他方の逆U字側壁に挿通されている。24は上側ボルト23の挿通端にねじ込まれたナットである。
【0013】
25は上側ボルト23にねじ込まれて、上側ボルト23の頭部寄りの逆U字側壁と重合された重り片22との間に配置されたナット、26は上側ボルト23に嵌合されて、重合された重り片22とナット25との間に配置された押さえ板、27は重合された重り片22の下縁部に挿通された下側ボルト、28は下側ボルト27の挿通端にねじ込まれたナットである。
【0014】
29は吊り枠14の積載室20の縁部と重合された重り片22とを締結する締結具で、上側ボルト23、ナット24、ナット25、押さえ板26、下側ボルト27及びナット28によって構成されている。9は上枠2に挿通されて係止されたエレベーター主索の引き止め具、10は吊り枠1の図1における四隅にそれぞれ装着されたガイドシュー、13は下横枠19に係止されて吊下された釣合いロープである。
【0015】
上記のように構成されたエレベーターのつり合おもりにおいて、吊り枠14の両側の側枠15と、水平に配置された上枠16、上横枠18等の横枠の間に複数の積載室20が形成される。そして、それぞれの積載室20に板状材からなり板面が鉛直に配置され複数枚が互いに重合された重り片22が積載される。そして、締結具29によって積載室20の縁部、すなわち吊り枠14に締結される。
【0016】
このようにして所要の質量に対応した個数の重り片22が積載室20に積載される。そして、重り片22を積載室20に搬入するための吊り枠14における上下方向の余裕空所を設ける必要がなく、吊り枠14の背丈を低くすることができる。また、積載室20の一部を、上枠16に係止された引き止め具9の主索の伸び調整、また下横枠19に係止されて吊下された釣合いロープ13の伸び調整のための余裕のスペースに当てることができる。
【0017】
したがって、吊り枠14の背丈を所要の質量に対応した個数の重り片22を積載するための、重り片22の自体の積載高さに対応した高さに設定することができる。このため、吊り枠14の背丈が低くなりつり合おもりの通常時の最上昇位置に対するエレベーターの昇降路の上端位置を下方に設定することができ、昇降路の全高が低くなって建築費を節減することができる。
【0018】
また、側枠15に前述の切欠部12を設ける必要がなく、吊り枠14の所要の強度を容易に得ることができる。また、前述の重り押さえ具11が不要になるので、部品数が減少し製造費を低減することができる。さらに、吊り枠14の図1おける左右に積載された重り片22の個数を適宜に加減して吊り枠14の左右バランスを調整することができる。これにより、つり合おもりの走行中にアンバランスに起因して発生する騒音を少なくすることができる。
【0019】
実施の形態2.
図4及び図5は、この発明の他の実施の形態の一例を示す図で、図4は正面図、図5は図4の縦断側面図である。図において、前述の図6及び図7と、図1〜図3と同符号は相当部分を示す。
図4及び図5の実施の形態は、前述の図6及び図7の構造の一部を、前述の図1〜図3の構造に置き換えたものである。したがって、詳細な説明を省略するが図4及び図5の実施の形態においても図1〜図3の実施の形態に準じた作用を得ることができる。
【0020】
【発明の効果】
この発明は以上説明したように、外側面に開口部を有し、鉛直方向に並んだ複数の積載室が設けられた吊り枠と、最上段の積載室内中央で、上方から吊り枠の上枠に挿通された主索に設けられ、下方から上枠に係止された引止め具と、水平投影面において引止め具と重合しない位置で、開口部を介して最上段の積載室両側に水平方向に着脱自在に設けられ、板面が鉛直に配置された複数枚が互いに鉛直投影面において重合された第1重り片と、水平投影面において引止め具と重合しない位置で、開口部を介して最上段以外の積載室両側に水平方向に着脱自在に設けられ、板面が鉛直に配置された複数枚が互いに鉛直投影面において重合された第2重り片と、水平投影面において引止め具と重合する位置で、開口部を介して最上段以外の積載室中央に水平方向に着脱自在に設けられ、板面が鉛直に配置された複数枚が互いに鉛直投影面において重合された第3重り片とを設けたものである。
【0021】
これによって、所要の質量に対応した個数の重り片が積載室に積載される。そして、重り片を積載室に搬入するための吊り枠における上下方向の余裕空所を設ける必要がなく、吊り枠の背丈を低くすることができる。また、積載室の一部を、上枠に係止された引き止め具の主索の伸び調整、また下横枠に係止されて吊下された釣合いロープの伸び調整のための余裕のスペースに当てることができる。したがって、吊り枠の背丈を所要の質量に対応した個数の重り片を積載するための、重り片の自体の積載高さに対応した高さに設定することができる。このため、吊り枠の背丈が低くなりつり合おもりの通常時の最上昇位置に対するエレベーターの昇降路の上端位置を下方に設定することができ、昇降路の全高が低くなって建築費を節減する効果がある。
【0022】
また、この発明は以上説明したように、積載室の縁部と積載室に積載された重り片とを締結する締結具を設けたものである。
【0023】
これによって、所要の質量に対応した個数の重り片が積載室に積載されて、重り片が積載室の縁部に締結される。そして、重り片を積載室に搬入するための吊り枠における上下方向の余裕空所を設ける必要がなく、吊り枠の背丈を低くすることができる。また、積載室の一部を、上枠に係止された引き止め具の主索の伸び調整、また下横枠に係止されて吊下された釣合いロープの伸び調整のための余裕のスペースに当てることができる。したがって、吊り枠の背丈を所要の質量に対応した個数の重り片を積載するための、重り片の自体の積載高さに対応した高さに設定することができる。このため、吊り枠の背丈が低くなりつり合おもりの通常時の最上昇位置に対するエレベーターの昇降路の上端位置を下方に設定することができ、昇降路の全高が低くなって建築費を節減する効果がある。
