Description

Die Erfindung betrifft eine Rohrhebevorrichtung mit Teleskopgabel, welche zur Verbindung von Rohren auf einer bestimmten Höhe Verwendung finden kann. Die Rohrhebevorrichtung kann auf einer Baustelle, in einem Gebäude aufgebaut werden und mit einem Hubwagen positioniert werden.The invention relates to a pipe lifting device with telescopic fork, which can be used for connecting pipes at a certain height use. The pipe lifting device can be built on a construction site, in a building and positioned with a lift truck.

Im Dokument US5489182A wird eine Lasthebevorrichtung offenbart, die zwischen Boden und Decke verspannt werden kann.In the document US5489182A discloses a load lifting device that can be clamped between floor and ceiling.

Eine Lasthebevorrichtung zum Heben von langgestreckten Gegenständen ist aus dem Deutschen Gebrauchsmuster DE202006015030U1 bekannt.A load lifting device for lifting elongated objects is from the German Utility Model DE202006015030U1 known.

Weiters ist eine Lasthebevorrichtung der Firma Genie bekannt, die als Superlift bezeichnet wird.Furthermore, a load lifting device of the company Genie is known, which is referred to as Superlift.

Aus DE102004018021A1 ist eine Lasthebevorrichtung zum Heben und horizontalem Bewegen von Lasten bekannt.Out DE102004018021A1 a lifting device for lifting and horizontal movement of loads is known.

Keine dieser Lasthebevorrichtungen eignet sich um Rohrverbindungen in einem Gebäude auf einer bestimmten Höhe in einer bestimmten Horizontallage auszuführen.None of these load lifting devices is suitable for performing pipe joints in a building at a certain height in a certain horizontal position.

Der Erfindung liegt demnach die Aufgabe zugrunde eine Rohrhebevorrichtung zu schaffen, welche es ermöglicht Rohre in einer bestimmten Höhe und bestimmte horizontale Lage zu bringen, die den Sicherheitsvorschriften entspricht, welche kompakt ist, leicht zu transportieren und leicht handzuhaben ist.The invention is therefore an object of the invention to provide a pipe lifting device, which makes it possible to bring pipes at a certain height and certain horizontal position, which complies with safety regulations, which is compact, easy to transport and easy to handle.

Die Rohrhebevorrichtung 1 wird anhand eines Ausführungsbeispiels erläutert. Sie besteht aus einem Untergestell 4 wie auf Fig. 11 dargestellt ist. Dieses wird mittels einer Stütze 8 z.B. der Firma Doka gegen die Decke 29 verspannt.The pipe lifting device 1 will be explained with reference to an embodiment. It consists of a base 4 as on Fig. 11 is shown. This is braced by means of a support 8, for example, the company Doka against the ceiling 29.

Am Untergestell 4 ist eine Säulenhalterung angebracht. An dieser Säulenhalterung wird das unterste Segment 7 der Säule 3 mittels Verschraubung befestigt. Die beiden weiteren Säulensegmente 5,6 und der Gabelschlitten, wie in Fig. 8-10 dargestellt, sind mittels Rollenlager ineinander geführt. Diese werden wiederum mittels Seilzugmechanismus und einer Seilwinde 28 geführt, gehoben und gesenkt. Für die gleichmäßige Belastung des obersten Säulensegmentes ist die Schwenkeinheit 24 des Gabelschlittens 9 verantwortlich. Dies geschieht mittels acht Rollen 21. Auf der Frontseite des Gabelschlittens 9 sind die Lagerböcke 22,23 angeschweißt. In den oberen Lagerböcken sind die Bolzen 27 fix eingeschweißt. In den unteren Lagerböcken sind die Bolzen 26 mit Schnellverschlussmechanismen ausgestattet. Die sind für die einfache Anbringung der gesamten Gabel 2 verantwortlich.On the base 4, a column holder is attached. At this column holder, the lowermost segment 7 of the column 3 is fastened by means of screwing. The two other column segments 5,6 and the fork carriage, as in Fig. 8-10 shown, are guided by roller bearings into each other. These are in turn guided, lifted and lowered by means of cable pull mechanism and a winch 28. For uniform loading of the uppermost column segment, the pivoting unit 24 of the fork carriage 9 is responsible. This is done by means of eight rollers 21. On the front side of the fork carriage 9, the bearing blocks 22,23 are welded. In the upper bearing blocks, the bolts 27 are fixed welded. In the lower bearing blocks, the bolts 26 are equipped with quick-release mechanisms. They are responsible for the simple attachment of the entire fork 2.

An einem Querträger 15 sind zwei Haken 10 angeschweißt. Diese Haken 10 werden in die Bolzen oben eingehängt und unten fixiert. Am Querträger 15 sind die Hinterträger 14 fix verschweißt. Der Mittelträger 13 und der Vorderträger 12 sind mittels Rollen 16,19,20,21 ausziehbar gelagert. Der Auszug ist mittels Auszugstopper 18 und Auszugstoppplättchen 17 begrenzt. An den beiden Vorderträgern ist eine verdrehbare Rohrauflage 11 angebracht. Diese besteht aus einem Teil der fest mit den beiden Vorderträgern verschweißt ist. Darauf ist ein weiteres Teil mittels einer Schraube drehbar gelagert. Auf diesem drehbaren Teil sind zwei Sicherungsgurte (nicht in den Zeichnungen dargestellt) zur Fixierung eines Rohres 30 angebracht.On a cross member 15 two hooks 10 are welded. These hooks 10 are in the bolts above hung and fixed at the bottom. On the cross member 15, the rear support 14 are fixed welded. The center support 13 and the front support 12 are mounted by means of rollers 16,19,20,21 extendable. The extract is limited by means of pull-out stopper 18 and pull-out stop plate 17. At the two front supports a rotatable pipe support 11 is attached. This consists of a part which is firmly welded to the two front supports. Then another part is rotatably mounted by means of a screw. On this rotatable part two safety straps (not shown in the drawings) for fixing a tube 30 are attached.

Die Anbringung der Stütze 8 ermöglicht es das Rohr in eine horizontale Lage zu bringen die über die Länge L2 des Untergestelles 4 herausragt. Das Rohr kann bis zu einer Länge L1 nach vorne geschoben werden. Ohne der Stütze 8 könnte das Rohr nur bis zum vorderen Ende des Untergestelles gebracht werden, bei einer Überschreitung würde die Hebevorrichtung kippen. Nach der Anbringung der Stütze 8 kann das Rohr 30 auf der Rohrauflage 11 abgelegt und mittels Gurte gesichert werden. Durch die Betätigung der Winde 28 wird das Rohr in die gewünschte Höhe gehoben. Anschließend bringt der Monteur durch ausschieben der Gabel 2 das Rohr 30 in die gewünschte horizontale Position. Dadurch kann das Rohr 30 über Hindernisse hinweggehoben werden. Da das Untergestell 4 nicht immer in der exakten Rohrachsposition fixiert werden kann, hat der Monteur die Möglichkeit es mittels der drehbaren Rohrauflage in die erforderliche Rohrposition zu bringen.The attachment of the support 8 makes it possible to bring the tube into a horizontal position which projects beyond the length L2 of the undercarriage 4. The tube can be pushed forward to a length L1. Without the support 8, the tube could only be brought to the front end of the undercarriage, if exceeded, the lifting device would tip over. After attachment of the support 8, the tube 30 can be placed on the pipe support 11 and secured by straps. By operating the winch 28, the tube is lifted to the desired height. Then brings the fitter by pushing out the fork 2, the tube 30 in the desired horizontal position. As a result, the tube 30 can be lifted over obstacles. Since the base 4 can not always be fixed in the exact position of the pipe axis, the installer has the opportunity to bring it by means of the rotatable pipe support in the required pipe position.

Um den Transport zu erleichtern ist die Hebevorrichtung in die drei Hauptbestandteile wie auf Fig.12 zerlegbar. Somit kann sie mittels Hubwagens transportiert werden.To facilitate transport, the lifting device is in the three main components as on Figure 12 dismantled. Thus, it can be transported by means of a lift truck.
