Description

Die Erfindung betrifft eine Strahlenschutzkabine für eine Röntgenvorrichtung, insbesondere ein Röntgenprüfsystem, wobei die Strahlenschutzkabine Wandplattenelemente und Profilelemente zum Tragen und/oder Verbinden der Wandplattenelemente aufweist.The invention relates to a radiation protection cabin for an X-ray device, in particular an X-ray inspection system, the radiation protection cabin wall panel elements and has profile elements for supporting and / or connecting the wall plate elements.

Eine Röntgenvorrichtung zur zerstörungsfreien Prüfung von Prüfteilen, beispielsweise Gußteilen, mittels Röntgenstrahlung ist im Innern einer Strahlenschutzkabine angeordnet und wird bei geschlossener Kabine betrieben. Die Wände der Kabine werden im wesentlichen von Wandplattenelementen mit einer Bleilage gebildet. Die Wandplattenelemente werden üblicherweise von Profilrohren getragen. An den Verbindungsstellen zwischen den Wandelementen entstehen Abschirmungslücken zwischen den Bleilagen der Wandplattenelemente. Um das Entweichen von Strahlung zu verhindern, werden an den Verbindungsstellen der Wandplattenelemente, beispielsweise außen, bleihaltige Leisten und Eckteile angebracht. Dies ist aufwendig und führt zu unerwünschten hervorstehenden Teilen an den Außenwänden der Strahlenschutzkabine.An x-ray device for the non-destructive testing of test parts, for example Castings by means of X-rays are arranged inside a radiation protection cabin and is operated with the cabin closed. The walls of the cabin are in essentially formed by wall plate elements with a lead layer. The wall panel elements are usually carried by profile tubes. At the connection points shielding gaps are created between the lead layers between the wall elements of the wall panel elements. To prevent the escape of radiation, be on the joints of the wall panel elements, for example outside, leaded Moldings and corner pieces attached. This is expensive and leads to unwanted protruding Parts on the outer walls of the radiation protection cabin.

Die Aufgabe der Erfindung besteht darin, eine Strahlenschutzkabine bereitzustellen, bei der der Herstellungsaufwand reduziert ist, ohne daß die Strahlenschutzfunktion beeinträchtigt wird.The object of the invention is to provide a radiation protection cabin, in which the manufacturing effort is reduced without impairing the radiation protection function becomes.

Die Erfindung löst diese Aufgabe mit den Mitteln des Anspruchs 1, insbesondere dadurch, daß die Profilelemente massiv ausgebildet sind. Die Erfindung nutzt ohnehin an den Verbindungsstellen der Wandplattenelemente vorhandene Profilelemente zur Strahlungsabschwächung. Die Röntgenstrahlen werden über den gesamten Querschnitt der massiven Profilelemente abgeschwächt und nicht wie herkömmlich nur in den Rohrwänden. Das Austreten von Röntgenstrahlung zwischen den Bleilagen der Wandplattenelemente kann daher im wesentlichen vollständig verhindert werden. Auf zusätzliche Abschirmungselemente, insbesondere Bleielemente, im Bereich der Verbindungsstellen der Wandplattenelemente der Strahlenschutzkabine kann daher erfindungsgemäß verzichtet werden. Dies verringert den Herstellungsaufwand der Strahlenschutzkabine. Gegebenenfalls kann eine Gewichtsreduzierung der Strahlenschutzkabine erreicht werden. Mittels innenliegender Profilelemente können über die Außenwände der Strahlenschutzkabine hervorstehende Teile vermieden werden, so daß im wesentlichen ebene Außenwände erreicht werden können.The invention solves this problem with the means of claim 1, in particular by that the profile elements are solid. The invention applies anyway the connection points of the wall panel elements existing profile elements for radiation attenuation. The x-rays are taken over the entire cross section of the massive profile elements weakened and not, as is conventional, only in the tube walls. The emergence of X-rays between the lead layers of the wall panel elements can therefore be substantially completely prevented. On additional Shielding elements, in particular lead elements, in the area of the connection points the wall plate elements of the radiation protection cabin can therefore be dispensed with according to the invention become. This reduces the manufacturing costs of the radiation protection cabin. Possibly the radiation protection cabin can be reduced in weight. Using internal profile elements, you can use the outer walls of the radiation protection cabin protruding parts are avoided, so that essentially flat External walls can be reached.

Bevorzugte Profilelemente aus Stahl verfügen über hohe Tragfähigkeit und hohe Strahlungsabsorption bei geringen Kosten.Preferred steel profile elements have a high load-bearing capacity and high radiation absorption at low cost.

Zweckmäßigerweise ist die Dimensionierung der Profilelemente ausreichend, um Strahlenschutz für übliche Röntgenprüfsysteme zu gewährleisten. Gewährleistung von Strahlenschutz bedeutet, daß im Betrieb der Röntgenvorrichtung keine oder allenfalls vernachlässigbar wenig Röntgenstrahlung, die in der Regel durch Grenzwerte definiert wird, aus der Strahlenschutzkabine entweicht. Vorzugsweise entspricht die Röntgenabsorption der Profilelemente mindestens etwa derjenigen von herkömmlich verwendeten Bleilagen, d.h. vorzugsweise von mindestens 2 mm, vorzugsweise mindestens 2.5 mm Blei. Vorzugsweise beträgt daher der Durchmesser der Profilelemente mindestens 20 mm, vorzugsweise mindestens 25 mm, weiter vorzugsweise mindestens 30 mm. Besonders vorteilhaft ist der Einsatz der Erfindung für Röntgenvorrichtungen mit mehr als 60 kV, vorzugsweise mehr als 100 kV und/oder mehr als 200 W, vorzugsweise mehr als 400 W, da bei diesen Energien bzw. Leistungen der Einsatz von zusätzlichen bleihaltigen Abschirmungen in herkömmlichen Strahlenschutzkabinen unverzichtbar ist.The dimensioning of the profile elements is expediently sufficient for radiation protection to ensure for common X-ray inspection systems. Guarantee of radiation protection means that during operation of the x-ray device none or negligible at most little x-ray radiation, which is usually defined by limit values is escaping from the radiation protection cabin. The x-ray absorption preferably corresponds the profile elements at least approximately that of conventionally used Lead layers, i.e. preferably at least 2 mm, preferably at least 2.5 mm Lead. The diameter of the profile elements is therefore preferably at least 20 mm, preferably at least 25 mm, more preferably at least 30 mm. Especially It is advantageous to use the invention for X-ray devices with more than 60 kV, preferably more than 100 kV and / or more than 200 W, preferably more than 400 W, because with these energies or powers the use of additional lead-containing ones Shielding is essential in conventional radiation protection cabins.

Die Erfindung ist auf sämtliche Wandplattenelemente tragende, verbindende und/oder begrenzende Profilelemente anwendbar. Dies betrifft mindestens Profilelemente an den Vertikalkanten der Strahlenschutzkabine, vorzugsweise auch Profilelemente an den Horizontalkanten der Strahlenschutzkabine. Vorzugsweise sind ebenfalls zwischen den Kanten der Strahlenschutzkabine angeordnete Profilelemente massiv ausgebildet. Die Erfindung betrifft vorzugsweise ebenfalls Profilelemente, die eine Öffnung der Strahlenschutzkabine insbesondere als Teil eines Rahmens begrenzen. Dabei kann es sich beispielsweise um eine Türöffnung bei begehbaren Strahlenschutzkabinen oder um Öffnungen zum Transportieren von Prüfteilen durch die Strahlenschutzkabine handeln. The invention applies to all wall panel elements, connecting and / or limiting profile elements applicable. This affects at least profile elements on the Vertical edges of the radiation protection cabin, preferably also profile elements on the horizontal edges the radiation protection cabin. Are preferably also between the Edges of the radiation protection cabin arranged profile elements solid. The The invention preferably also relates to profile elements that have an opening in the radiation protection cabin limit especially as part of a framework. It can be for example around a door opening in walk-in radiation protection cabins or around openings act to transport test parts through the radiation protection cabin.

Bei einer bevorzugten Ausführungsform weisen die Wandplattenelemente über deren Oberfläche hervorstehende Befestigungsmittel zum Befestigen der Wandplattenelemente an den Profilelementen auf. Mittels der hervorstehenden Befestigungsmittel kann die Befestigungsstelle von den Wandplattenelementen und der darin enthaltenen Bleilage beabstandet werden. Dies ist insbesondere bei einer Schweißverbindung vorteilhaft, da durch den vergrößerten Abstand zwischen der Schweißstelle und der Bleilage eine Erhitzung des Bleis erheblich verringert werden kann. Eine Erhitzung des Bleis könnte zur Verringerung der Bleistärke durch Verlaufen des Bleis und damit zur Beeinträchtigung des Strahlenschutzes fuhren. Der auf die Befestigungsmittel gerichtete Anspruch 10 ist gegebenenfalls eigenständig, d.h. in einer nur auf den Oberbegriff des Anspruchs 1 rückbezogenen Form beanspruchbar. Die Aufgabe eines solchen Anspruchs besteht darin, eine Strahlenschutzkabine mit verbesserter Strahlenschutzsicherheit bereitzustellen, bei der insbesondere eine Beeinträchtigung des Strahlenschutzes im Bereich von Schweißstellen zwischen den Wandplatten- und Profilelementen vermieden wird.In a preferred embodiment, the wall panel elements have over them Surface protruding fasteners for fastening the wall panel elements on the profile elements. By means of the protruding fastening means, the Fastening point of the wall panel elements and the lead layer contained therein be spaced. This is particularly advantageous in the case of a welded connection, since heating due to the increased distance between the weld and the lead layer of lead can be significantly reduced. Heating the lead could lead to Reduction in lead strength due to bleeding of the lead and thus impairment of radiation protection. The claim 10 directed to the fasteners if necessary independently, i.e. in one only on the preamble of claim 1 claimable back-related form. The purpose of such a claim is to provide a radiation protection cabin with improved radiation protection safety, in which an impairment of radiation protection in the range of Welds between the wall plate and profile elements is avoided.

Vorzugsweise sind die Befestigungsmittel aus einem ohnehin vorhandenen Teil der Wandplattenelemente, insbesondere einer Verkleidung gebildet, beispielsweise durch Abkanten von Blechlaschen aus der Verkleidung, was den Herstellungsaufwand reduziert. Die Befestigungsmittel sind auf sämtliche Verbindungen zwischen Profilelementen und Wandplattenelementen anwendbar.The fastening means are preferably made of an already existing part of the Wall plate elements, in particular a panel formed, for example by Folding sheet metal tabs out of the cladding, which reduces the manufacturing effort. The fasteners are on all connections between profile elements and wall plate elements applicable.

In der Strahlenschutzkabine 10 ist eine in Fig. 1 schematisch angedeutete Haltevorrichtung 30 für ein Prüfteil angeordnet. An einer Seitenwand 11 der Strahlenschutzkabine 10 ist ein Röntgenmanipulator 32 an Haltemitteln 31 befestigt. Die Seitenwände 11-14 der Strahlenschutzkabine 10 werden im wesentlichen von einer Mehrzahl von Wandplattenelementen 15 gebildet. Die Bodenwand sowie die nicht gezeigte Deckenwand der Strahlenschutzkabine 10 werden zweckmäßigerweise ebenfalls von Wandplattenelementen 16 gebildet. Die Wände der Strahlenschutzkabine 10 umfassen die Seitenwände 11-14, die Bodenwand und die Deckenwand. Die folgenden Erläuterungen betreffen im wesentlichen die Seitenwände 11-14; vorzugsweise weisen jedoch auch die Deckenwand und/oder die Bodenwand der Strahlenschutzkabine 10 die anhand der Seitenwände erläuterten bevorzugten Merkmale entsprechend auf.In the radiation protection cabin 10 is a holding device schematically indicated in FIG. 1 30 arranged for a test part. On a side wall 11 of the radiation protection cabin 10, an X-ray manipulator 32 is attached to holding means 31. The side walls 11-14 the radiation protection cabin 10 are essentially made up of a plurality of wall plate elements 15 formed. The bottom wall and the ceiling wall of the, not shown Radiation protection cabin 10 are also expediently made of wall plate elements 16 formed. The walls of the radiation protection cabin 10 include the side walls 11-14, the bottom wall and the top wall. The following explanations relate to essentially the side walls 11-14; however, preferably also have the ceiling wall and / or the bottom wall of the radiation protection cabin 10 which is based on the side walls explained preferred features accordingly.

Die Wandplattenelemente 15 sind an Profilelementen 20-25 befestigt und werden von diesen getragen. Es müssen jedoch nicht sämtliche Profilelemente 20-25 eine tragende Funktion aufweisen. Profilelemente 20-24 sind insbesondere an den Verbindungsstellen zwischen den Wandplattenelementen 15, 16 vorgesehen. Es sind insbesondere Profilelemente 20 an den Vertikalkanten der Strahlenschutzkabine 10, vorzugsweise weiterhin Profilelemente 21 zwischen den Vertikalkanten, Profilelemente 24 an den Horizontalkanten und/oder Profilelemente 22 zwischen den Horizontalkanten der Strahlenschutzkabine 10 vorgesehen. An der Seitenwand 11 können ebenfalls nicht gezeigte Profilelemente zwischen den Vertikalkanten zum Verbinden der die Seitenwand 11 bildenden Wandplattenelemente vorgesehen sein.The wall plate elements 15 are attached to profile elements 20-25 and are from worn this. However, not all profile elements 20-25 need to be load-bearing Have function. Profile elements 20-24 are in particular at the connection points provided between the wall plate elements 15, 16. They are especially profile elements 20 on the vertical edges of the radiation protection cabin 10, preferably further Profile elements 21 between the vertical edges, profile elements 24 on the horizontal edges and / or profile elements 22 between the horizontal edges of the radiation protection cabin 10 provided. On the side wall 11 can also not shown Profile elements between the vertical edges for connecting the side wall 11 forming Wall plate elements may be provided.

Die Wandplattenelemente 15 weisen eine äußere Verkleidung 17 beispielsweise aus Blech, eine innere Verkleidung 18 beispielsweise aus Blech und eine Abschirmungslage 19 insbesondere aus Blei auf. An den Verbindungsstellen zwischen den Wandplattenelementen 15 treten Abschirmungslücken zwischen den Bleilagen 19 auf, wie am besten in Fig. 2 erkennbar. Bei herkömmlichen Strahlenschutzkabinen sind daher Leisten, Kantenleisten bzw. Eckteile zur Abdeckung dieser Abschirmungslücken außen an der Strahlenschutzkabine angebracht. Bei der vorliegenden Strahlenschutzkabine 10 sind die Profilelemente 20-24 massiv ausgeführt, d.h. sie bestehen im wesentlichen über ihren gesamten Querschnitt aus Vollmaterial, vorzugsweise Stahl, und sind insbesondere hohlraumfrei ausgeführt. Röntgenstrahlung, die auf die Verbindungsstellen zwischen den Wandplattenelementen 15 gerichtet ist, tritt daher durch den vollen Querschnitt der Profilelemente 20-24 und wird darin im wesentlichen vollständig absorbiert. Zusätzliche bleihaltige Abschirmungselemente sind nicht erforderlich.The wall panel elements 15 have an outer cladding 17, for example Sheet metal, an inner cladding 18 made of sheet metal, for example, and a shielding layer 19 especially lead. At the junctures between the wall panel elements 15 shielding gaps occur between the lead layers 19, as best recognizable in Fig. 2. In conventional radiation protection cabins there are strips, edge strips or corner parts to cover these shielding gaps on the outside of the radiation protection cabin appropriate. In the present radiation protection cabin 10, the profile elements 20-24 solid, i.e. they exist essentially over all of them Cross section made of solid material, preferably steel, and are in particular free of voids executed. X-rays emitted at the junctions between the Wall plate elements 15 is directed, therefore occurs through the full cross section of the profile elements 20-24 and is essentially completely absorbed therein. additional shielding elements containing lead are not required.

Die begehbare Strahlenschutzkabine 10 weist eine Türöffnung 26 für Bedienpersonal auf. Die Türöffnung 26 ist im Betrieb der Röntgenvorrichtung 30 durch eine Tür 27 verschlossen, die eine Bleilage 28 enthält. Die Tür 27 kann aus der in den Fig. 1, 3 gezeigten geschlossenen Position in Pfeilrichtung mittels nicht gezeigten Führungen in eine geöffnete Position verschoben werden. Der Rahmen der Türöffnung 26 umfaßt Profilelemente 25 als Rahmenteile. Die Tür 27 umfaßt Profilteile 29, die vorzugsweise an der in den Innenraum der Strahlenschutzkabine 10 weisenden Seite der Tür 27 angeordnet sind. Die Profilelemente 25, 29 sind massiv und vorzugsweise aus Stahl ausgeführt und greifen im geschlossenen Zustand der Tür 27 vorzugsweise ineinander, so daß auf die Abschirmungslücke zwischen Tür 27 und angrenzenden Wandplattenelementen 15 gerichtete Röntgenstrahlung wirksam abgeschirmt wird. Zusätzliche bleihaltige Abschirmungen, beispielsweise herkömmliche winkelförmige, im geschlossenen Zustand der Tür einander hintergreifende Bleielemente an der Tür und dem Türrahmen sind daher nicht erforderlich.The walk-in radiation protection cabin 10 has a door opening 26 for operating personnel on. The door opening 26 is in operation of the x-ray device 30 through a door 27 closed, which contains a lead layer 28. The door 27 can be of the type shown in FIGS. 1, 3 closed position in the direction of the arrow by means of guides not shown in an open position can be moved. The frame of the door opening 26 includes Profile elements 25 as frame parts. The door 27 comprises profile parts 29, which are preferably arranged on the side of the door 27 pointing into the interior of the radiation protection cabin 10 are. The profile elements 25, 29 are solid and preferably made of steel and preferably engage in the closed state of the door 27 so that on the shielding gap between door 27 and adjacent wall plate elements 15 directed X-rays are effectively shielded. Additional shields containing lead, for example conventional angular, when closed Leading elements behind the door on the door and the door frame are therefore not mandatory.

Die am Beispiel der Tür 27 erläuterten Merkmale können entsprechend für andere nicht gezeigte Öffnungen der Strahlenschutzkabine 10, beispielsweise Öffnungen zum Transportieren von Prüfteilen durch die Strahlenschutzkabine, gelten. Statt der in den Figuren gezeigten einteiligen Tür 27 kann auch eine Zweiflügeltür vorgesehen sein.The features explained using the example of the door 27 cannot correspondingly apply to others Openings shown in the radiation protection cabin 10, for example openings for transportation of test parts by the radiation protection cabin apply. Instead of that in the figures one-piece door 27 shown can also be provided a double-leaf door.

Die Röntgenvorrichtung 30 wird vorzugsweise mit einer Röntgenröhre im Bereich von 60 - 200 kV, beispielsweise 160 kV, mit einer Röhrenleistung im Bereich von 300 - 3000 W, beispielsweise 640 W betrieben. Der Durchmesser der Profilelemente 20-24 beträgt vorzugsweise mindestens 25 mm, beispielsweise etwa 35 mm, was der Absorption von etwa 2 - 2.5 mm Blei entspricht. Der Durchmesser bezeichnet den kleinsten Querschnittsdurchmesser, bei quadratischem Querschnitt als beispielsweise die Quadratkantenlänge.The x-ray device 30 is preferably provided with an x-ray tube in the range of 60 - 200 kV, for example 160 kV, with a tube power in the range of 300 - 3000 W, for example 640 W operated. The diameter of the profile elements 20-24 is preferably at least 25 mm, for example about 35 mm, which is the absorption of about 2 - 2.5 mm lead. The diameter denotes the smallest Cross-sectional diameter, for a square cross-section, for example, the square edge length.

Die Wandplattenelemente 15, 16 können mittels Schweißverbindungen 41 an den entsprechenden Profilelementen 20-25 befestigt sein. Im Bereich der Verbindungsstellen zwischen Wandplattenelementen 15, 16 und Profilelementen 20-25 sind Ausschneidungen 42 in der Blechverkleidung 18 eines Wandplattenelements 15 vorgesehen, wie aus Fig. 4, 5 ersichtlich. Im Bereich der Ausschneidung 42 ist die Blechverkleidung 18 in Form einer Lasche 40 abgekantet. Die Lasche 40 ist im Beispiel der Fig. 4, 5 ins Innere der Strahlenschutzkabine 10 gebogen. Die Schweißverbindung 41 ist an der freien Außenkante 43 der Lasche 40 angeordnet. Wie aus Fig. 4 ersichtlich, weist die Schweißverbindung 41 infolge der Lasche 40 einen erheblich größeren Abstand von der Bleilage 19 des Wandplattenelements 15 auf, als wenn die Lasche 40 nicht vorhanden wäre. Die Erhitzung der Bleilage 19 beim Schweißen der Schweißverbindung 41 wird hierdurch soweit verringert, daß ein nachteiliges Verlaufen der Bleilage 19 im Bereich der Verbindungsstelle vermieden wird und eine im wesentlichen gleichmäßige Stärke der Bleilage 19 sichergestellt ist.The wall plate elements 15, 16 can be welded 41 to the corresponding Profile elements 20-25 be attached. In the area of the connection points between wall plate elements 15, 16 and profile elements 20-25 are cutouts 42 provided in the sheet metal cladding 18 of a wall plate element 15, as from 4, 5 can be seen. The sheet metal cladding 18 is in the region of the cutout 42 Form of a tab 40 folded. The tab 40 is in the example of FIGS. 4, 5 inside the radiation protection cabin 10 bent. The weld joint 41 is on the free outer edge 43 of the tab 40 arranged. As can be seen from Fig. 4, the welded connection 41 due to the tab 40 a significantly larger distance from the lead layer 19 of the wall plate element 15 as if the tab 40 were not present. The Heating of the lead layer 19 when welding the welded joint 41 is thereby reduced to the extent that an adverse run of the lead layer 19 in the area of the connection point is avoided and a substantially uniform thickness of the lead layer 19 is ensured.
