Abstract
Description
Vorrichtung zur Innenauskleidung von Device for the inner lining of
Rohren mit Zementmörtel bzw. plastischen Schutzschichten zur Erzielung höchster Maßgenauigkeit und Oberflächenglätte. Pipes with cement mortar or plastic protective layers to achieve highest dimensional accuracy and surface smoothness.
Die Erfindung betrifft eine Vorrichtung für die Innenauskleidung von Rohren bzw. Hohlkörpern mit Zementmörtel bzw. plastischen oder plastifizierbaren Materialien, an deren Schichtbeschaffenheit erhöhte Anforderungen bezüglich der Maßhaltigkeit und Oberflächenglätte gestellt werden.The invention relates to a device for the inner lining of Pipes or hollow bodies with cement mortar or plastic or plasticizable Materials whose layer properties have increased requirements with regard to Dimensional accuracy and surface smoothness are provided.
Alle bekannten Verfahren der Innenauskleidung von Rohren resp. Hohlkörpern mit Zementmörtel setzen voraus, daß die zu behandelnden Rohre einen möglichst kreisrunden Innenquerschnitt aufweisen, wenn die erzielten Schutzschichten eine gleichmäßige Dichte bei gleichzeitig hoher Oberflächenglätte aufweisen sollen.All known methods of inner lining of pipes, respectively. Hollow bodies with cement mortar assume that the pipes to be treated are as circular as possible Have internal cross-section if the protective layers achieved are uniform Should have density with high surface smoothness at the same time.
Diese Voraussetzungen treffen sowohl für fabrikmäßig ausgekleidete Rohre und Hohlkörper, die ausschließlich nach dem Schleuderverfahren hergestellt werden und bei denen der vorher in die Rohre eingefüllte Zementmörtel durch Rotation fer Rohre und die dabei bewirkten Zentripetalkräfte an der Innenwandung aufgetragen wird, als auch fUr die Verfahren der nachträglichen Auskleidung zu, bei denen entweder Schleudergeräte od.r zylindrische Körper durch die Rohre gedrückt oder gezogen werden. Die Maßgenauigkeit der nach diesen Verfahren erzielten Schichtdicken steht in direkter Abhängigkeit von der Maßgenauigkeit des Innendurchmessers des Hohlkörpers, die von der Ovalitäts- und Wanddickentoleranz bestimmt wird.These requirements meet for both factory-lined Pipes and hollow bodies, which are produced exclusively by the centrifugal process and where the cement mortar previously poured into the pipes by rotation fer pipes and the resulting centripetal forces applied to the inner wall will, as well as for the process of retrofitting, where either Centrifugal devices or cylindrical bodies are pushed or pulled through the pipes. The dimensional accuracy of the layer thicknesses achieved by this method is more direct Dependence on the dimensional accuracy of the inner diameter of the hollow body, which is of the ovality and wall thickness tolerance is determined.
Bei der Verwendung von Schleudergeräten ist die Schichtdicke noch am ehesten unabhängig von den Rohr- bzw. Hohlkörpertoleranzen, allerdings läßt die Oberflächenglätte der aufgetragenen Schutzschicht erheblich zu wünschen übrig, da die bereits vorhandene Schicht durch die Kinetische Energie des anschließend aufgeschleuderten Materials immer wieder aufgerissen und beschädigt wird.When using centrifugal devices, the layer thickness is still most likely independent of the pipe or hollow body tolerances, but leaves the Surface smoothness of the applied protective layer left a lot to be desired, since the already existing layer through the kinetic energy of the subsequently thrown up Material is repeatedly torn open and damaged.
Der Erfindung lag die Aufgabe zugrunde, eine Vorrichtung zu entwickeln, mittels der auch bei extrem großen Toleranzen des Innendurchmessers Schutzschichten gleichiäßiger Dicke bei gleichzeitig hoher Oberflächenglätte erzielt werden können.The invention was based on the object of developing a device by means of the protective layers even with extremely large tolerances of the inner diameter uniform thickness with high surface smoothness can be achieved at the same time.
Die Vorrichtung besteht aus einem Zentrierungs-und Führungskolben (1), der über anstellbare Rollen (2) achsial durch den Hohlkörper gleitet.The device consists of a centering and guide piston (1), which slides axially through the hollow body on adjustable rollers (2).
Durch diesen zylindrischen Führungs- und Zentrierungskolben führt eine drehbare gelagerte Hohlwelle (3), an deren Ende sich eine fest mit der Hohlwelle verbundene :Winkeldüse (4) befindet.Leads through this cylindrical guide and centering piston a rotatable mounted hollow shaft (3), at the end of which one is firmly attached to the hollow shaft connected: angled nozzle (4) is located.
Ebenfalls mit der Drehachse verbunden ist eine Glättvorrichtung (5), die gegenüber der Düse in Umfangsrichtung versetzt in der gleichen Schnittebene fieber ein Gelenk schwenkbar angeordnet ist und deren Abstand von der Rohrinnenoberfläche mittels der Tastrolle (6) konstant gehalten wird.A smoothing device (5) is also connected to the axis of rotation, which are offset in the circumferential direction in relation to the nozzle in the same cutting plane fever a joint is pivotably arranged and its distance from the inner surface of the pipe is kept constant by means of the feeler roller (6).
Die Tastrolle fahrt die Kontur des Rohrinnenmantels im noch nicht beschichteten Bereich ab und übernimmt damit die Steuerfunktion für die Glättvorrichtung, die verstellbar angeordnet ist, um die gewünschte Schichtdicke vorher einstellen zu können.The feeler roller does not yet travel the contour of the inner pipe jacket coated area and thus takes over the control function for the smoothing device, which is arranged to be adjustable in order to set the desired layer thickness beforehand to be able to.
Der Arbeitsablauf bei der Innenbeschichtung geht so vonstatten, daß der Zementmörtel unter Druck durch de stufenlos drehbare Hohlwelle (n) und Winkeldüse (4) der Rohrinnenoberfläche zugeführt wird, wobei sich die vorzugsweise mittels -ederkraft angepreßte Glättvorrichtung (5), gesteuert durch die Tastrolle (6), gleichzeitig synchron mitdreht und das aufgetragene Beschichtungsgut verdichtet und glättet.The internal coating is carried out in such a way that the cement mortar under pressure through the continuously rotatable hollow shaft (s) and angled nozzle (4) is fed to the inner surface of the pipe, which is preferably by means of -ederkraft pressed smoothing device (5), controlled by the feeler roller (6), simultaneously rotates synchronously and the applied coating material is compacted and smoothed.
