Fig. 1 shows a device 1 for cleaning aninner wall 5 of aline 3, as used for example in hydropower plants in pressure lines. The water flowing in the discharge lines causes deposits, dirt and corrosion to form on the inner walls. In addition, the piping is usually provided with an interior coating which no longer provides the necessary protection and no longer meets today's standards and regulations, so that they must be disposed of ,
Die
Der Rotationsantrieb des im Wesentlichen aus Welle 8 und Strahlrohren 9 gebildeten Strahlaggregates 2 besteht aus einem Elektromotor 21, der mit dem Gestell 4 fest verbunden ist, und einer umlaufenden Kette 22 oder einem Riemen, der ein auf der Welle 8 sitzendes Kettenrad 23 resp. Riemenrad antreibt. Zur gestellseitigen Befestigung des Elektromotors 21 eignet sich ein Support 24, auf dem der Elektromotor 21 festgeschraubt ist.
Dem Strahlaggregat 2 wird das Strahlmittel an einem dem Zugseil-Befestigungsende 25 gegenüberliegenden Gestellende zugeführt und das Strahlaggregat 2 sowie der diesem zugeordnete Rotationsantrieb 26, bestehend aus dem mit dem Gestell 4 verbundenen Elektromotor 21, der Kette 22 und dem auf der Welle 8 sitzenden Kettenrad 23, ist in Leitungsführungsrichtung betrachtet zwischen den Gestellenden resp. den Lagerböcken 14, 15 resp. den Stützelementen 16, 17 angeordnet. Die Drehzahl des Rotationsantriebs 26 kann zur Anpassung an die herrschenden Umstände resp. die Hartnäckigkeit zur Entfernung der Fremdstoffe über eine nicht dargestellte Steuerung geändert werden.
Die Verbindung von dem Strahlaggregat 2 zu einer Strahlmittelquelle erfolgt durch eine flexible Druckleitung 7, die mittels Kupplung 28 mit der rotierenden Welle 8 resp. der Druckleitung 7 verbunden ist. Selbstverständlich kann die flexible Druckleitung 27 auch als Zugmittel der Einrichtung 1 in einer Leitungsführungsrichtung dienen. Der einrichtungsseitige Kupplungsteil der Kupplung 28 ist verdrehsicher an dem Gestell 4 befestigt.The rotary drive of the

Die in einer stark verschmutzten Umgebung hohen Belastungen ausgesetzten Antriebs- und Lagerelemente der Einrichtung 1 und der Reinigungsvorgang erfordern eine ständige Kontrolle und werden durch eine Kamera überwacht. Um die verschleissanfälligen Antriebs-, Lager- und andere Elemente auf der Baustelle resp. in der Leitung 3 umgehend austauschen zu können, bedarf es -wie vorgeschlageneinfacher Mittel und Möglichkeiten zur Behebung eines Stillstandes der Einrichtung 1. Deshalb ist die Lagerung der Welle 8 durch zwei Schalenhälften 46, 47 zur Bildung einer die Wälzlager 43 an den Aussenringen aufnehmenden Lagerschale 48 ausgebildet.The in a heavily polluted environment high loads exposed drive and bearing elements of the device 1 and the cleaning process require constant control and are monitored by a camera. To the wear-prone drive, bearing and other elements on the site resp. Therefore, the bearing of the
Ebenso ist der zwischen den Lagerböcken 14, 15 der Welle 8 zugeordnete Rotationsantrieb 26 mit einem einfach ersetzbaren Kettenrad 23 ausgebildet, das aus zwei Radhälften besteht und mit einer auf der Welle 8 festsitzenden Nabe 50 lösbar verbunden ist. Die Antriebskette 22 kann durch Trennen resp. Zusammenfügen zweier Kettenglieder auf einfache Art ersetzt oder repariert werden. Dadurch können Defekte an der Einrichtung 1 innerhalb der Leitung 3 behoben werden, sofern der Querschnitt der Leitung 3 den Zugang des Servicepersonals zur Einrichtung 1 erlaubt. Die Bauweise gestattet einen einfachen Umgang und Unterhalt mit der Einrichtung 1 in Leitungen 3 mit unterschiedlichen Querschnitten und erlaubt die Behebung eines Defekts an der Einrichtung 1 ohne Auflösung der Anlageinstallation. Die Einrichtung 1 wird zur Reinigung einer Leitung 3 entlang der Innenwand 5 resp. Innenwände bei eckigem Leitungsquerschnitt über ein mit einer Winde verbundenes Zugseil 6 hinuntergelassen und/oder hochgezogen resp. bei horizontalem Leitungsverlauf oder geringem Gefälle geschleppt. Das Zugseil 6 verbindet die Winde mit der Einrichtung 1 durch eine an dem Gestellende vorgesehene Befestigungsvorrichtung 30, beispielsweise einem Haken oder einer Oese.Likewise, between the
In der Regel wird die Einrichtung 1 so eingesetzt, dass das Strahlmittel von unten aus einem Auffangbecken der Einrichtung 1 zugeführt wird und das Zugseil 6 an dem gegenüberliegenden Ende des Gestells 4 angebracht ist, sodass das zum Abbau der Fremdstoffe von unten zugeführte Strahlmittel an der Innenwand 5 ab- resp. zurückfliessen und von dem Auffangbecken aufgenommen wird. Dadurch kann das mit einem hohen Wasseranteil versehen Strahlmittel und dessen Belastung kontrolliert aufbereitet und ggf. entsorgt werden.In general, the device 1 is used so that the blasting agent is supplied from below from a catch basin of the device 1 and the
Die Einrichtung 1 eignet sich insbesondere für eine verfahrensmässige Anwendung, wenn sie in einen Strahlmittelkreislauf geschaltet ist, in dem das Strahlmittel aus einem mit der Leitung 3 verbundenen Auffangbecken der Einrichtung 1 zugeführt und entlang der Innenwand 5 der Leitung 3 in das Auffangbecken zurückgeführt wird. Die Rückführung des Strahlmittels in das Auffangbecken kann durch ein Leitungsgefälle oder eine Pumpe erfolgen.The device 1 is particularly suitable for a procedural application when it is connected in a blasting medium circuit in which the blasting agent is supplied from a connected to the
