Definitions
- 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.
- 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.
- 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 pressure 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-Vertriebs, D 2305 Heikendorf : "Accessories for channel maintenance").
- 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.
- the chassis has a rectangular cross section; that a long side of the chassis is provided with a folding device; that the piston is attached to the chassis; that the lifting cylinder is non-positively connected to a first pressure head; that a second pressure head is non-positively connected to the chassis on the side opposite the lifting cylinder and that an oil pressure pump is provided which can be connected in terms of flow to the lifting cylinder via a pressure hose.
- the service life of the high-pressure hoses is prolonged, since scraping and kinking at the deflection point are excluded.
- the latching device in the device according to the invention can be locked in such a way that after the flap equipped with a hinge is closed, a pin is inserted through a hole provided in the chassis.
- 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.
- 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.
- a guide roller 2 is rotatably arranged in a chassis 1 having a rectangular cross section.
- the chassis 1 also has on its one long side a folding device 3 for inserting the hose.
- the longitudinal sides of the chassis 1 can be connected in the region of the guide roller 2 by means of a plug element 4.
- a lifting piston 5, which is movable in a lifting cylinder 6, is attached to the chassis 1 on one side.
- a first pressure head 7 is non-positively connected to the lifting cylinder 6, while a second pressure head 8 is non-positively connected to the chassis on the opposite side of the lifting cylinder 6.
- a first stop angle 9 is arranged horizontally pivotably perpendicular to the axis of the guide roller 2, while a second stop angle 10 is arranged between the second pressure head 8 and the chassis 1 in a height-adjustable manner.
- the second stop bracket 10 is provided at the end of its height-adjustable leg with an eyelet 11 for attaching a tether.
- an oil pressure pump 12 is connected in terms of flow to the lifting cylinder 6 via a pressure hose 13.
- the high-pressure hose with the cleaning nozzle located at one end is inserted into the chassis 1 with the folding device 3 open.
- the pressure hose 13 is connected on the one hand to the oil pressure pump 12 and on the other hand to the lifting cylinder 6.
- a rope is attached to the eyelet 11 and the device according to the invention is lowered into the sewer shaft to the desired depth.
- the horizontal leg of the second stop angle 10 is inserted into the channel at the lower edge of the pipe apex, as a result of which the second pressure head 8 is fixed.
- the first stop bracket 9 With sufficient visibility in the channel, the first stop bracket 9 is pivoted in the direction of the chassis 1, while in the presence of vapors in the channel, the swiveled-out second stop bracket 9 is inserted with its horizontal leg into the channel at the lower edge of the pipe apex, whereby the first contact head 7 is fixed.

Abstract
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 pressure 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-Vertriebs, 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. Das wird erfindungsgemäß dadurch erreicht, daß das Chassis einen rechteckigen Querschnitt aufweist; daß eine Längsseite des Chassis mit einer Klappeinrichtung versehen ist; daß am Chassis der Hubkolben befestigt ist; daß der Hubzylinder mit einem ersten Anpreßkopf kraftschlüssig verbunden ist; daß ein zweiter Anpreßkopf auf der dem Hubzylinder entgegengesetzten Seite mit dem Chassis kraftschlüssig verbunden ist und daß eine Öldruckpumpe vorgesehen ist, welche über einen Druckschlauch mit dem Hubzylinder strömungsmäßig verbindbar ist.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.
