Description

【発明の詳細な説明】 濃厚物質用ポンプ 本発明は、材料集配槽と、その端面側の開口部でもって材料集配槽の内部に開 口する2つの搬送シリンダと、材料集配槽内に嵌入し、軸方向に移動可能な摩耗 リングを担持するその1端でもって行程毎に交互に搬送シリンダの端面側開口部 と連通し、かつその他端でもって搬送管に接続しているS字状旋回管とを備える 濃厚物質用ポンプにして、該旋回管が搬送管側端部に対し同心にありかつ搬送シ リンダの上方に配置された水平軸心の周りに旋回可能であり、その場合旋回管に 、ほぼ旋回管全長に亘り延びかつ槽底部の近くまで達する下方を指向する空間リ ブが成形されている濃厚物質用ポンプに関する。 この形式の濃厚物質用ポンプでは、搬送材が1つの搬送シリンダのピストンの 後退過程の間に材料集配槽からこのシリンダ内に吸引され、これに対し他の搬送 シリンダの同時期のピストン前進過程では、この搬送シリンダに吸引された搬送 材が旋回管を通過して搬送導管内に押圧される。旋回管に配置された摩耗リング は、その都度の搬送シリンダの押圧行程にて旋回管が搬送シリンダの端面側開口 部の境界をなす眼鏡状摩耗板に対し密に接合するように機能し、それによって搬 送材の液体または微粒子成分がこの位置で搬送材から分離するのを防止する。こ の目的のために、摩耗 リングは、これが押圧行程にて搬送圧力の作用の下に摩耗板に押圧されるように 構成されている。旋回管の切り替えに際し摩耗リングおよび眼鏡状摩耗板に生ず る磨滅のために、旋回管は時折材料集配槽内部で軸方向に移動させて調整しなけ ればならない。このため、旋回管軸受の範囲に外部から手の届く調整ねじが配置 されている。旋回管はS字状に湾曲しているので、構造により材料集配槽内部で 多かれ少なかれ大きな死空間が存在し、ここに濃厚物質材が集積し得ることにな る。従って、各ポンプの終了後に材料集配槽を空にし、丹念に清掃することが重 要である。死空間を小さくするため、材料集配槽を特に底部範囲にて旋回管のS 字状形に適合させることは、既に提案されている。しかし、これは著しい構成上 の経費を必要とする。 この欠点を解消するため、旋回管に成形されかつ槽底部近くまで延びる空間リ ブが既に提案された。これによって、材料集配槽を比較的簡単に構成しても、動 かない搬送材が集積する大きな死空間の生じないことが達成される。 本発明の課題は、当初に述べた形式の周知の濃厚物質用ポンプを改良し、押圧 行程における旋回管と搬送シリンダとの間の確実な密封を保証することである。 この課題を解決するため、本発明は、空間リブが、旋回管の摩耗リングの反対 側にあるその端部に、旋回軸心に垂直をなす摩耗板を担持し、この摩耗板が搬送 管側槽壁に設けられかつ特にこの槽壁に対し軸平行に調整可能な摩耗帯状体に接 合していることを 提案する。このため、摩耗板は摩耗リングの高さに配置され、これに対し旋回管 は後側壁の回転軸受に軸方向に調整可能に装着されるのが有利である。摩耗板と 付属の摩耗帯状体は、旋回管・回動軸受の範囲における軸方向の限定を不要とす る支持軸受を形成し、そしてこの支持軸受は、さらに、押圧行程時に軸動シャフ トに引張力および曲げ力が作用しないことを保証する。またこれによって、磨滅 の生じた場合、材料集配槽内にて旋回管を簡単にかつ好都合に調整することが、 切替機構の範囲に付加的な取付け構成なしに可能となる。 これに関連して、摩耗帯状体が、搬送管側槽壁の貫通孔内に配置され、この貫 通孔に対し密封され、かつ該槽壁の外側に配置された調整機構でもって移動可能 となっている調整材に配置されるようにすることにより、さらなる改善が達成さ れる。 空間リブは、両旋回方向を指向しかつ旋回軸心と摩耗リング軸心とを含む半径 面に対し鏡像対称的に設けられた間口面部により境界されるのが有利である。底 部にある搬送材が、切替過程毎に槽底部から持ち上げられ、その上にある搬送材 と混合され得るように、本発明の有利な実施例では、空間リブの間口面部が、底 側の自由リブ縁部の方へリブ縁部厚みを増大しながら互いに反対側の方に、特に ほぼ90°外方に凹んで湾曲している。この場合、材料集配槽は、旋回軸心に対 し同心の部分円筒状である製作容易な底部を有し、これに対し槽底部の方に向い たリブ縁部は同じく旋回軸心に対しほぼ同軸の部分円筒状の凸状湾曲を有するこ とが できる。 部分円筒状の底部を有する材料集配槽の構造が簡単なので、搬送管側槽壁部が 材料集配槽と取外し可能に結合され、従って組立と解体のため簡単に取り外すこ とが可能となる。 以下に、本発明を図面により説明する。 図1は、S字状旋回管を具備する2シリンダ濃厚物質用ポンプの材料集配槽の 断面図である。 図2は、S字状旋回管を具備する材料集配槽の別の実施例の図1に対応する断 面図である。 図3は、図1の線III−IIIによる断面図である。 図に部分図として示す2シリンダ濃厚物質用ポンプは、定置のおよび走行可能 なコンクリートポンプ装置に使用されるものである。この濃厚物質用ポンプは、 対向する行程で駆動される図示しない搬送ピストンを具備する2つの搬送シリン ダ10と、材料集配槽14と、この材料集配槽14内に嵌入しかつ逆転機構18 により作動可能なS字状旋回管16とよりなる。搬送シリンダ10は、下側範囲 にて開口部22を介して材料集配槽14の後側壁24に接続されており、その場 合開口部22は材料集配槽14の内側にて眼鏡状摩耗板26により境界されてい る。旋回管16は、摩耗リング28を担持するその1端で摩耗板26に接合し、 そして逆転機構18により搬送シリンダ10内における搬送ピストンの運動方向 に依存して、1つの開口部22または他の開口部の前に旋回する。このようにし て、搬送ピストンの戻り運動時に材料 は材料集配槽10から開口部22を通って当該搬送シリンダ10内に吸引され、 これに対し他の搬送ピストンを介して材料は旋回管16を通って材料集配槽14 の外にある搬送管30内に搬送される。搬送管30は、図示しないコンクリート 配分マストの搬送導管に接続することができる。 図1に示す実施例においては、ほぼS字状に構成された旋回管が、摩耗リング 28に対向するその端部32に、旋回管の旋回軸心34に同軸にある槽固定の管 回動結合部36を介して搬送管30と結合されており、これに対し図2に示す実 施例では、旋回管の搬送管側端部32が当該槽壁40に設けた簡単な回動実施部 38を通って導かれている。後者の場合、別の管回動結合部を必要に応じ備えた 外部回転軸受が必要である。槽壁40は、いずれの場合でも、組立ておよび解体 のため材料集配槽から取外し可能となっている。 後側壁24の範囲にて、旋回管は駆動軸として構成された軸動シャフト42で もって材料集配槽14の回転軸受44に嵌入し貫通している。軸動シャフト42 は、材料集配槽14の外側にて逆転機構18により旋回軸心34の周りに二重矢 印46(図3)の方向に限定して往復旋回せしめられる。図3に示すように、材 料集配槽14の底部48はその全長に亘り同心的に部分円筒状に湾曲している。 材料集配槽14内部の死空間を大いになくするために、旋回管16には、ほぼ旋 回管全長に亘り延び、かつ槽底部48の近くまで達する下方を指向する空間リブ 50が成形されてい る。この空間リブ50は、両旋回方向を指向し、かつ旋回軸心34と摩耗リング 軸心52とを含む半径面54に対し鏡像対称的に設けられた間口面部56により 境界されている。間口面部56は、底側の自由リブ縁部の方へリブ縁部厚みを増 大しながら互いに反対側の方に外方に凹んで湾曲しており、そして底部に近い範 囲の搬送材が切替え過程毎に上方へ掻きまわされるように作用する。槽底部48 の方に向いたリブ縁部58は、図示の実施例では、旋回軸心34に対し同軸の部 分円筒式に凸状の湾曲を有するので、槽底部とリブ縁部との間には狭いすき間6 0があるのみである。 さらに、空間リブ50は、旋回管の摩耗リング28に対し反対側の端部に、旋 回軸心34に対し垂直をなしかつ摩耗リング28の高さに配置された摩耗板62 を担持している。摩耗板62は、槽壁40に設けられかつこれに対し軸平行に調 整可能な摩耗帯状体64に接合している。摩耗帯状体は、この目的のために、調 整材に配置されており、この調整材は槽壁40の貫通孔66内に挿着され、この 貫通孔に対し密封され、かつ槽壁40の外側に配置された調整機構68でもって 移動可能となっている。摩耗帯状体64は、旋回管に対し、旋回管軸受の範囲で 軸方向の限定を不要となし、そして軸動シャフト42の引張応力と曲げ応力とを 防ぐ支持軸受として機能する。さらに、この手段によって、摩耗リング28およ び眼鏡状摩耗板26の範囲にて磨滅の生じた場合、旋回管を簡単に調整すること が可能である。 結局、次のようにまとめることができる。 本発明は、特にコンクリートを搬送するための濃厚物質用ポンプに関する。該 濃厚物質用ポンプは、材料集配槽14と、その端面側の開口部22でもって材料 集配槽14の内部に開口する2つの搬送シリンダ10と、S字状旋回管とを備え 、この旋回管は材料集配槽14内に嵌入し、その1端でもって行程毎に交互に搬 送シリンダ10の端面側開口部22と連通し、そしてその他端でもって搬送管3 0に接続している。該旋回管は、その搬送管側端部32に対し同心にありかつ搬 送シリンダ10の上方に配置された水平旋回軸心34の周りに旋回可能である。 旋回管16には、ほぼ旋回管全長に亘り延び、かつ槽底部48の近くまで達する 空間リブ50が成形されている。空間リブ50は、搬送シリンダ10の反対側に あるその端部に旋回軸心34に垂直をなす摩耗板64を有し、この摩耗板は搬送 管側槽壁40に設けられかつこれに対し軸平行に調整可能な摩耗帯状体64に接 合している。DETAILED DESCRIPTION OF THE INVENTION                             Pumps for concentrated substances   According to the present invention, the material collecting and distributing tank and the opening on the end face side open the material collecting and distributing tank.
