Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Umlenken von Hochdruckschläuchen für Strahlwassersysteme zur Reinigung von Abwasserkanälen, die aus zwei Anpreßeinheiten besteht, wobei eine Anpreßeinheit als Chassis ausgebildet ist, in welchem eine Führungsrolle drehbar angeordnet ist und die Anpreßeinheiten durch eine aus Hubzylinder und Hubkolben aufgebaute Einrichtung auf Abstand voneinander einstellbar sind.The present invention relates to a device for deflecting high-pressure hoses for jet water systems for cleaning sewers, which consists of two pressure units, wherein a pressure unit is designed as a chassis in which a guide roller is rotatably arranged and the pressure units by a device constructed from a lifting cylinder and a piston Distance from each other are adjustable.

Die Reinigung von Abwasserkanälen von Feststoffen kann so erfolgen, daß Wasser unter hohem Druck aus einer nach dem Rückstoßprinzip konstruierten Reinigungsdüse austritt und damit die Feststoffe stufenweise zu einem Auffangraum transportiert, aus welchem die Feststoffe dann entfernt werden. Dabei werden die Hin- und Herbewegungen der Reinigungsdüse im Abwasserkanal durch Abrollen bzw. Aufwickeln eines langen Hochdruckschlauches von einer Haspel bewirkt, wobei der Hochdruckschlauch an seinem der Reinigungsdüse entgegengesetztem Ende mit einem Gerät zur Erzeugung von Hochdruckwasser strömungsmäßig verbunden ist. Die Einfädelung des Hochdruckschlauches mit der Reinigungsdüse an seinem Ende in den Abwasserkanal ist nur über einen Kanalschacht im Abwasserkanal möglich, wobei der Hochdruckschlauch an der Umlenkstelle Kanalschacht/Abwasserkanal bei seiner Hin- und Herbewegung mindestens abgeschürft, wenn nicht gar abgeknickt wird, wodurch die Lebensdauer des Hochdruckschlauches relativ kurz ist. Da der Gestehpreis je Meter Hochdruckschlauch beträchtlich ist, sind bereits Geräte entwickelt worden, um die Lebensdauer von zur Abwasserkanalreinigung eingesetzten Hochdruckschläuchen zu verlängern.Solids can be cleaned from sewers in such a way that water emerges under high pressure from a cleaning nozzle constructed according to the recoil principle and thus the solids are gradually transported to a collecting space from which the solids are then removed. The back and forth movements of the cleaning nozzle in the sewer are effected by unrolling or winding up a long high-pressure hose from a reel, the high-pressure hose at its end opposite the cleaning nozzle being connected in terms of flow to a device for producing high-pressure water. The threading of the high-pressure hose with the cleaning nozzle at its end into the sewer is only possible via a sewer shaft in the sewer, the high-pressure hose at the deflection point of the sewer shaft / sewer being at least abraded, if not kinked, as it moves back and forth, thereby reducing the service life of the High pressure hose is relatively short. Since the cost price per meter of high-pressure hose is considerable, devices have already been developed to extend the life of high-pressure hoses used for sewer cleaning.

So ist im Handel eine hydraulische Umlenkrolle erhältlich, welche aus zwei Anpreßeinheiten besteht, die im Abwasserkanal mit Hilfe eines Hydraulikzylinders klemmend befestigbar sind. Während die eine Anpreßeinheit ein Winkelprofil aufweist und mit dem Hubkolben verbunden ist, wird die andere Anpreßeinheit von einem Chassis gebildet, in welchem eine Führungsrolle drehbar gelagert ist und welche mit dem Hubkolben verbunden ist (vergl. Prospekt der Firma roditec Vertrieb, D 2305 Heikendorf: "Zubehörteile zur Kanalerhaltung").A hydraulic deflection roller is commercially available, which consists of two pressure units that can be clamped in the sewer with the help of a hydraulic cylinder. While one pressure unit has an angular profile and is connected to the reciprocating piston, the other pressing unit is formed by a chassis in which a guide roller is rotatably mounted and which is connected to the reciprocating piston (see brochure from roditec Vertrieb, D 2305 Heikendorf: "Accessories for channel maintenance").

Nachteilig ist bei der bekannten hydraulischen Umlenkrolle, daß zu ihrer Anbringung eine Person in den Kanalschacht einsteigen muß, wobei wegen der Ungewißheit über die Zusammensetzung der Gasphase im Abwasserkanal und im Kanalschacht erheblicher Sicherheitsaufwand erforderlich ist.A disadvantage of the known hydraulic deflection roller is that a person has to climb into the sewer shaft in order to attach it, whereby considerable uncertainty is required because of the uncertainty about the composition of the gas phase in the sewer and in the sewer shaft.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Umlenken von Hochdruckschläuchen für Strahlwassersysteme zur Reinigung von Abwasserkanälen, welche aus zwei Anpreßeinheiten ― davon eine als Chassis mit Führungsrolle ausgebildet ― und aus einer aus Hubzylinder und Hubkolben aufgebauten Einrichtung besteht, anzugeben, wobei die Vorrichtung vom Hüttenflur aus in den Abwasserkanal eingebracht und arretiert werden kann, ohne daß eine Person in den Kanalschacht einsteigen muß.It is therefore an object of the present invention to provide a device for deflecting high-pressure hoses for jet water systems for cleaning sewers, which consists of two pressure units - one of which is designed as a chassis with a guide roller - and of a device constructed from a lifting cylinder and a piston, the device can be inserted and locked into the sewer from the hallway, without anyone having to enter the sewer shaft.

e)
between the second pressure head and the chassis, a second stop angle in the plane of the guide roller is arranged adjustable in height;
f)
the second stop bracket is provided with an eyelet for receiving a tether at the end of its height-adjustable leg.

Mit der erfindungsgemäßen Vorrichtung wird die Lebensdauer der Hochdruckschläuche verlängert, da Schürfen und Knicken an der Umlenkstelle ausgeschlossen ist.With the device according to the invention, the service life of the high-pressure hoses is prolonged, since scraping and kinking at the deflection point are excluded.

Die Arretierung der Klappeinrichtung bei der Vorrichtung gemäß der Erfindung kann so erfolgen, daß nach Schließen der mit einem Scharnier ausgerüsteten Klappe ein Stift durch eine mit einer Bohrung versehene Ausnehmung im Chassis hindurchgesteckt wird.The latching device in the device according to the invention can be locked in such a way that after closing the hinged flap, a pin is inserted through a recess in the chassis provided with a hole.

Die erfindungsgemäße Vorrichtung wird an einem Seil, welches mit der am Ende des höhenverstellbaren Schenkels des zweiten Anschlagwinkels befindlichen Öse mit Hilfe eines Schäkels verbunden ist, in den Kanalschacht hinabgelassen.The device according to the invention is lowered into the sewer shaft on a rope which is connected to the eyelet at the end of the height-adjustable leg of the second stop angle with the aid of a shackle.

Durch das Steckelement wird bei der Vorrichtung gemäß der Erfindung verhindert, daß der Hochdruckschlauch im Betriebszustand von der Führungsrolle abspringt.The plug element in the device according to the invention prevents the high-pressure hose from jumping off the guide roller in the operating state.
