Baubeschreibung eines Transportwagens für die EohrverlegungDescription of the construction of a transport trolley for laying pipes

Wenn Versorgungsleitungen (Gas, Waseer) Straßen und Autobahnen kreuzen, wird beim Bau der Straßen ein Betonrohr als Schutzrohr unter die Fahrbahndake eingebaut. Beim späteren Verlegen der Versorgungsleitung muß diese in das Schutzrohr geschoben werden.When supply lines (gas, water) cross roads and highways, a concrete pipe is used as a protective pipe under the roadway when the roads are being built built-in. When laying the supply line later, it must be pushed into the protective tube.

Bisher wurden dafür zum Teil Holzkufen und zum Teil Transportwagen ähnlich meinem Torschlag, aber mit Laufrädern verwendet. Die Holzkufe erscheint als ungeeignet, da sie durch ständige Feuchtigkeit in dem Schutzrohr zu schnell verrottet und verfault. Das Rohr ist dadurch nicht mehr richtig gelagert. Die gebräuchlichen Transportwagen laufen auf starr geführten Laufrädern, die ein Hochfahren an der Schutzrohrwandung und ein Abkippen über ein Laufrad begünstigen.So far, some wooden runners and some transport trolleys have been similar my goal stroke, but used with running wheels. The wooden runner appears unsuitable, because constant moisture in the protective tube rots and rots too quickly. The pipe is no longer correct as a result stored. The common transport trolleys run on rigidly guided running wheels, which are raised against the protective tube wall and tipped favor over an impeller.

Die Neuentwicklung meiner Transportrollen ermöglicht eine mehrdimensionale Verschiebung und eine jeweils senkrechte Belastung der beiden Laufkugeln.The new development of my transport rollers enables a multi-dimensional Displacement and vertical loading of the two running balls.

Der Transportwagen besteht aus einer Rohrschelle, welche aus zwei Teilen, Ober- und Unterschelle besteht. Mit nach den Rohrgrößen erforderlichen Schrauben werden beide Teile an die gewünschte Stelle geklemmt. Besonders ist bei den Klemmschrauben zu erwähnen, daß sie bei dieser Konstruktion (siehe Zeichnung l) unmittelbar an der Schelle angeordnet ist und dadurch eine relativ günstige Kraftübertragung erfolgt und ungünstige Biegung auf die Schelle vermeidet. Das Schellenunterteil erhält zwei Stück aufgeschweißte Präzisionsrohrstutzen, worin ein Kugelsitz eingeschweißt ist. In das Präzisionsrohr wird auf den Kugelsitz eine genau passende Stahlkugel gelagert. Das Präzisionsrohr, welches ca. 5 mm über die Mittellinie der Kugel ragt, wird über die Kugel in einem Spezialverfahren gebördelt. Smmit hat die Kugel ihre feste Führung und kann nicht aus dem Lager fallen (siehe Zeichnung 2).The transport trolley consists of a pipe clamp, which consists of two parts, an upper and a lower clamp. Both parts are clamped in place with the screws required for the pipe sizes. In the case of the clamping screws, it should be mentioned in particular that in this construction (see drawing 1) they are arranged directly on the clamp and thus a relatively favorable transmission of force takes place and avoids unfavorable bending on the clamp. The lower part of the clamp has two precision pipe sockets welded on, into which a ball seat is welded. A precisely fitting steel ball is placed in the precision tube on the ball seat. The precision tube, which protrudes approx. 5 mm above the center line of the ball, is flanged over the ball in a special process. The ball has its fixed guidance and cannot fall out of the bearing (see drawing 2).

Der Transportwagen wird an Rohrverbindungen gleichzeitig als Muffenanker verwendet. Jeweils wird eine Schelle vor und ein Transportwagen hinter der Rohrmuffe verschraubt. Beide Schellen werden in Rohrrichtung über die Muffe gespannt.The transport trolley is also used as a sleeve anchor on pipe connections used. A clamp is screwed in front of and a transport trolley behind the pipe socket. Both clamps are in the direction of the pipe over the socket tense.
