Description
Die Erfindung betrifft eine teleskopisch ausziehbare Tragsäule, und zwar insbesondere eine Stativsäule, wie sie beispielsweise zur Aufstellung oder Aufhängung von Röntgenapparaten benötigt wird.The invention relates to a telescopic Support column, in particular a stand column, such as that used for setting up or hanging up is required by X-ray machines.
Es sind Tragsäulen dieser Art bekannt, bei denen die mit Zwischenräumen ineinandergeschobenen Rohre zur Erleichterung der Längsbewegungen durch Kugellager aneinander geführt und durch ineinandergreifende Teile benachbarter Rohre am gegenseitigen Verdrehen verhindert werden.There are known support columns of this type in which the tubes pushed into one another with gaps to facilitate the longitudinal movements guided by ball bearings together and by interlocking Parts of adjacent pipes are prevented from twisting against one another.
Gemäß der Erfindung übernehmen die Lagerkugeln im Zusammenspiel mit in den Rohren angeordneten Längsführungsteilen nicht nur die reibungsfreie Führung beim Auseinanderziehen und Zusammenschieben der Säule, sondern auch die Sicherung gegen das Verdrehen der einzelnen Rohre gegeneinander. Zu diesem Zweck weisen jeweils benachbarte Rohre einander gegenüberstehende Längsnuten zur Aufnahme der Lagerkugeln auf. Die Kugeln führen dabei zwar die Rohre bei ihrer gegenseitigen Längsbewegung im wesentlichen reibungsfrei, kuppeln sie aber in der Umfangsrichtung und verhindern dadurch das Verdrehen der Rohre gegeneinander, so daß besondere Mittel hierfür nicht erforderlich sind.According to the invention, the bearing balls take over in interaction with those arranged in the tubes Longitudinal guide parts not only provide friction-free guidance when pulling apart and pushing together the column, but also the protection against twisting of the individual tubes against each other. To this Purpose each adjacent tubes have opposite longitudinal grooves for receiving the Bearing balls. The balls lead the pipes in their mutual longitudinal movement in the essentially friction-free, but they couple in the circumferential direction and thereby prevent twisting the pipes against each other, so that special means are not required for this.
Die zur Aufnahme der Kugeln zweckmäßig rinnenförmigen Nuten sind in den Werkstoff der Rohrwände eingedrückt, so daß sie auf der Gegenseite Wulste bilden. Da diese versteifend wirken, können Rohre aus verhältnismäßig dünnem Blech verwendet werden, so daß sie vergleichsweise leicht sind und damit die ganze Säule im Verhältnis zu ihrer Standfestigkeit und Tragfähigkeit ein niedriges Gewicht erhält. Zudem ist die Säule entsprechend der einfachen Gestaltung billig herzustellen. The channel-shaped for receiving the balls is expedient Grooves are pressed into the material of the pipe walls so that they bulge on the opposite side form. Since these have a stiffening effect, tubes made of relatively thin sheet metal can be used, see above that they are comparatively light and thus the whole column in relation to their stability and load-bearing capacity gets a low weight. In addition, the column is inexpensive to manufacture in accordance with the simple design.
Die Zeichnung veranschaulicht die Erfindung an einem Ausführungsbeispiel.The drawing illustrates the invention using an exemplary embodiment.
Fig. 1 ist eine Seitenansicht der neuen Teleskopsäule, und zwar in einer Ausführung zur Aufhängung einer Röntgenröhre in fahrbarer Anordnung.Fig. 1 is a side view of the new telescopic column, specifically in an embodiment for the suspension of a X-ray tube in a mobile arrangement.
Fig. 2 ist eine Ansicht der Säule der Fig. 1 in voll ausgezogenem Zustand.Fig. 2 is a view of the column of Fig. 1 in its fully extended condition.
Fig. 3 ist ein waagerechter Schnitt nach der Linie 3-3 der Fig. 1 durch das obere Ende der Teleskopsäule bei vollständig zusammengeschobenen Rohren.Fig. 3 is a horizontal section along line 3-3 of Fig. 1 through the upper end of the telescopic column with the pipes pushed together completely.
Fig. 4 ist ein vergrößerter Teillängsschnitt nach der Linie 4-4 der Fig. 3.FIG. 4 is an enlarged partial longitudinal section along the line 4-4 of FIG. 3.
Die in der Zeichnung als Hängestativ für eine Röntgenröhre dargestellte neue Teleskopsäule kann für viele Zwecke und in anderen Ausführungsformen Anwendung finden.The new telescopic column shown in the drawing as a hanging stand for an X-ray tube can be used by many Purposes and apply in other embodiments.
Die rohrförmige Teleskopsäule 10 kann an einem Traggehäuse 12 aufgehängt sein, das mittels Rollen 15, 16 auf Schienen 14 läuft. Die Schienen sind ihrerseits auf einer Fahrbahn 17 mit Hilfe von Rollen 18 und 19 Teleskopische TragsäuleThe tubular telescopic column 10 can be suspended from a support housing 12, which by means of rollers 15, 16 runs on rails 14. The rails are in turn on a track 17 with the aid of rollers 18 and 19 Telescopic support column

as dieTeleskopsäule bei unveränderter Höhenlage in jeder Richtung beweglich. Am unteren Ende der Teleskopsäule ist eine Muffe 20 befestigt, die eine durchgehende hohle rohrförmige Achse aufnimmt. An dieser ist an einem Ende ein Halter 22 und am andern Ende eine Fokusierungslampe 23 befestigt. Der Halter 22 trägt eine Röntgenröhre 24, die also mit dem Halter um die in der Muffe 20 gelagerte rohrförmige Achse drehbar ist. Die Röntgenröhre selbst ist in dem Halter 22 um eine zur Achse der Muffe 20 senkrechte Achse schwenkbar. as the telescopic column with unchanged altitude in each Movable direction. At the lower end of the telescopic column, a sleeve 20 is attached, which is a continuous receives hollow tubular axle. At this end there is a holder 22 and at the other end one Focusing lamp 23 attached. The holder 22 carries an X-ray tube 24, so the holder around the in the sleeve 20 mounted tubular axis is rotatable. The X-ray tube itself is in the holder 22 µm an axis perpendicular to the axis of the sleeve 20 is pivotable.
Dem selbsttätigen Heben und Senken der rohrförmigen Säule kann ein im Tragkasten 12 untergebrachter Elektromotor 25 dienen. Mit diesem ist ein biegsames Zugorgan 26 verbunden, das über Führungsrollen 27 läuft und dann abwärts durch den mittleren Hohlraum der rohrförmigen Säule zu einem Punkt geht, an dem sein Ende mit dem innersten und untersten Rohr der Teleskopsäule verbunden ist.The automatic raising and lowering of the tubular column can be accommodated in the support box 12 Electric motor 25 are used. A flexible pulling element 26 is connected to this, which via guide rollers 27 runs and then descends through the central cavity of the tubular column to a point where its end is connected to the innermost and lowest tube of the telescopic column.
Die Teleskopsäule besteht aus mehreren, nach der Zeichnung beispielsweise aus sieben ineinander verschiebbaren konzentrischen zylindrischen Rohren 1 bis 7. Der Innendurchmesser eines jeden Rohres ist größer als der Außendurchmesser des nächstinneren Rohres, so daß zwischen zwei benachbarten RohrenThe telescopic column consists of several, for example seven according to the drawing, which can be slid into one another concentric cylindrical tubes 1 to 7. The inside diameter of each tube is larger than the outer diameter of the next inner tube, so that between two adjacent tubes
So stets ringförmige Hohlräume 9 vorhanden sind. Dies macht die genaue Bearbeitung zusammenpassender zylindrischer Oberflächen der ineinandergesteckten Rohre, wie sie bei bekannten Teleskopsäulen nötig war, entbehrlich. Das äußerste Rohr 7 weist auf seinerSo there are always annular cavities 9. this makes the precise machining of mating cylindrical surfaces of the nested Tubes, as they were necessary with known telescopic columns, can be dispensed with. The outermost tube 7 points to his
