Abstract

Die zur Wiederaufrichtung eines Zementgemisches fördernden Förderschlauches (30) vorgesehenen Stützorgane sind beiderseits des Förderschlauches (30) angeordnet und jeweils aus einer Vielzahl von nebeneinanderliegenden Stützelementen (35) ausgebildet. Diese sind in Achsrichtung der Preßwalze (40) bzw. senkrecht zur Längsrichtung des Förderschlauches (30) gleitbar ausgebildet und stehen durch die Wirking eines Pneumatikschlauches (46) jeweils in Richtung zum Förderschlauch (30) unter Vorspannung. Sobald die Stützelemente (35) im Bereich des Quetschprofiles (49) des Förderschlauches (30) in Richtung zum Pneumatikschlauch (46) verdrängt werden, kommt es dadurch zu einer erhöhten Krafteinwirkung der Stützelemente (35) in Richtung zum Förderschlauch, die schließlich nach Entfernung der Preßwalze (40) eine Verdrängung der Stützklötze (35) in ihre ursprüngliche Ausgangslage und damit ein Wiederaufrichten des gequetschten Förderschlauches (30) bewirkt (Fig.6.). Those promoting the re-erection of a cement mixture Conveyor hose (30) provided support members are on both sides of the conveyor hose (30) and each consisting of a Multitude of adjacent support elements (35) educated. These are in the axial direction of the press roll (40) or perpendicular to the longitudinal direction of the conveyor hose (30) slidably trained and stand by the effect of a Pneumatic hose (46) each in the direction of the delivery hose (30) under tension. As soon as the support elements (35) in the area of Crush profile (49) of the conveyor hose (30) in the direction are displaced to the pneumatic hose (46) an increased force of the support elements (35) in Direction to the delivery hose, which eventually after removal the press roll (40) a displacement of the support blocks (35) in their original starting point and thus a re-erection of the squeezed delivery hose (30) causes (Fig.6.).
