Description

Die Erfindung betrifft ein Gitterrost zum Chargieren und zur industriellen Warmbehandlung von Gegenständen in Öfen, bestehend aus kammartig ineinander gesteckten sich rechtwinklig kreuzenden Leisten aus kohlenstofffaserverstärktem Kohlenstoff oder aus Graphit.The invention relates to a grating for charging and for the industrial heat treatment of objects in ovens, consisting of comb-like meshed perpendicularly intersecting strips made of carbon fiber reinforced carbon or graphite.

Zum Chargieren von verschiedensten Gegenständen, wie Härtegut, oder anderweitig thermisch zu behandelndem Gut, werden verschiedene Gestelle, die auch als Transportrahmen, Steckroste, Gitterroste, Chargiergestelle bezeichnet werden, und aus Edelstahlguss oder auch aus Graphit bzw. CFC (kohlenstofffaserverstärkter Kohlenstoff) oder anderen geeigneten Materialien bestehen, eingesetzt. Die Gitterroste dienen der Aufnahme, der Lagerung und dem Transport von Gegenständen in und aus thermischen Prozessanlagen.For charging a variety of items, such as hardened material, or otherwise thermally treated Good, various racks, which are also referred to as transport frames, grids, gratings, charging racks, and made of cast stainless steel or graphite or CFC (carbon fiber reinforced carbon) or other suitable Materials exist, used. The gratings are used for receiving, storing and transporting objects in and out of thermal processing plants.

Ein Beispiel für einen solchen Gitterrost geht aus der DE 10 2006 004 902 A1 hervor. Die Längs- und Querstege des Gitterrostes sind durch Steckverbindungen miteinander verbunden und bestehen aus kohlenstofffaserverstärktem Kohlenstoff.An example of such a grid is from the DE 10 2006 004 902 A1 out. The longitudinal and transverse webs of the grid are connected by plug-in connections and are made of carbon fiber reinforced carbon.

Diese Gitterroste werden entweder in Standardabmessungen, oder als Sonderanfertigung, eingesetzt. Teilweise werden einzelne Gitterroste durch wechselseitig verankerte Stege zu größeren Flächen verbunden, um größere oder mehrere Gegenstände aufnehmen zu können.These gratings are used either in standard dimensions, or as custom-made. Partly individual gratings are connected by mutually anchored ridges to larger areas to accommodate larger or multiple items can.

Nachteilig an Gitterrosten in Standardgröße ist, dass diese nur eine Ofengröße abdecken. Sonderanfertigungen sind nicht universell einsetzbar. Das bedeutet, dass in Abhängigkeit von der Ofengröße verschiedene Gitterroste benötigt werden.A disadvantage of standard size gratings is that they only cover one furnace size. Custom-made products are not universally applicable. This means that different gratings are needed depending on the size of the oven.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Steckrost zur industriellen Warmbehandlung zu schaffen, das bei einer deutlich verbesserten Belastbarkeit zu flächenmäßig größeren Elementen einfach und belastbar zusammengefügt werden kann.The invention is therefore an object of the invention to provide a plug-in grid for industrial heat treatment, the can be combined with a significantly improved load capacity for larger area elements simple and resilient.

Die der Erfindung zugrunde liegende Aufgabe wird bei einem Gitterrost der eingangs genannten Art dadurch gelöst, dass in parallel zueinander verlaufenden Leisten, eine Vielzahl von mit Öffnungen versehenen Aufnahmebuchsen nebeneinander symmetrisch zu der Längserstreckung der Leisten eingesetzt sind, derart dass die Öffnungen zu den Öffnungen benachbarter Leisten fluchten und dass in den Öffnungen parallel nebeneinander verlaufende Tragstäbe angeordnet sind.The object underlying the invention is achieved in a grating of the type mentioned in that in a plurality of mutually parallel strips, a plurality of apertured receiving sockets are used side by side symmetrically to the longitudinal extent of the strips, such that the openings to the openings of adjacent strips aligned and that in the openings parallel side by side extending support rods are arranged.

Die Tragstäbe erstrecken sich bevorzugt mindestens über die gesamte Breite des Gitterrostes.The support rods preferably extend at least over the entire width of the grid.

Um eine sichere Aufnahme der Tragstäbe zu gewährleisten, sind die Aufnahmebuchsen mit den Leisten jeweils fest verbunden.To ensure a secure recording of the support rods, the receiving sockets are firmly connected to the strips.

In einer Fortführung der Erfindung sind mindestens zwei benachbarte Gitterroste zu größeren Elementen zusammengefügt, indem sich die Tragstäbe jeweils durchgehend durch die benachbarten Gitterroste erstrecken.In a continuation of the invention, at least two adjacent gratings are joined together to form larger elements, in that the support rods each extend continuously through the adjacent gratings.

Im Interesse einer hohen Belastbarkeit sind die Tragstäbe bevorzugt rohrförmig ausgebildet und können aus Graphit, CFC oder auch aus Metall bestehen.In the interest of a high load capacity, the support rods are preferably tubular and can be made of graphite, CFC or metal.

Um zu verhindern, dass zusammengesteckte Gitterroste während der Handhabung auseinanderrutschen könnten, ist es von Vorteil, wenn die Tragstäbe entgegen einer Friktion in die Aufnahmebuchsen einschiebbar sind.In order to prevent that mated gratings could slip apart during handling, it is advantageous if the support rods are inserted against a friction in the receiving sockets.

In einer weiteren Fortführung der Erfindung sind miteinander verbundene Gitterroste mit Hilfe von modularen Abstandshaltern/Stützen in einem vorgegebenen Abstand übereinander gestapelt, wobei die Abstandshalter/Stützen jeweils in den Ecken der Gitterroste angeordnet sind.In a further continuation of the invention interconnected gratings are by means of modular spacers / supports at a predetermined distance stacked on top of each other, with the spacers / pillars respectively disposed in the corners of the gratings.

Im Interesse einer guten Handhabbarkeit sind die Abstandshalter/Stützen formschlüssig und straff in die Ecken der Gitterroste eingesetzt.In the interests of good handling, the spacers / supports are positively and tightly inserted into the corners of the gratings.

Durch die Erfindung wird eine erhebliche Kosteneinsparung beim Einsatz solcher Gitterroste erreicht. Weiterhin werden durch die Erfindung universelle Module für kleine und große Öfen geschaffen, so dass nur noch ein Grundmodul für alle Öfen erforderlich ist. Die einzelnen Module sind individuell kombinierbar und zeigen beim Handling gegenüber herkömmlichen Gitterrosten keine Nachteile. Auch sind die erfindungsgemäß ausgestatteten Gitterroste mit den modularen Abstandshaltern/Stützen einfach stapelbar.By the invention, a significant cost savings in the use of such gratings is achieved. Furthermore, universal modules for small and large furnaces are created by the invention, so that only one basic module for all ovens is required. The individual modules can be individually combined and show no disadvantages in handling compared to conventional gratings. The gratings equipped according to the invention with the modular spacers / supports are also easily stackable.

Außerdem sind derartige Gitterroste in der Werkstatt einfach zu handhaben und ermöglichen eine einfache Wartung und Reparatur.In addition, such gratings are easy to handle in the workshop and allow easy maintenance and repair.

Die Erfindung soll nachfolgend an einem Ausführungsbeispiel näher erläutert werden. In den zugehörigen Zeichnungen zeigen:

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawings show:
Fig. 1:
an inventively equipped grating;
Fig. 2:
two gratings joined together in one plane Fig. 1 and
3:
a stacking arrangement of several assembled and stacked gratings after Fig. 1 ,

Gemäß Fig. 1 sind eine Vielzahl von längs und quer verlaufenden Leisten 1, 2, sich einander rechtwinklig kreuzend und ein Gitterrost 3 bildend, formschlüssig und kammartig ineinander gesteckt. Der Gitterrost 3 kann einen quadratischen oder rechteckigen Umriss aufweisen.According to Fig. 1 are a variety of longitudinal and transverse bars 1, 2, crossing each other at right angles and forming a grid 3, form-fitting and comb-like inserted into each other. The grid 3 may have a square or rectangular outline.

Bei diesem Gitterrost 3 sind in parallel zueinander verlaufenden Leisten 1 oder 2, in Fig. 1 sind das die längeren Leisten 1, eine Vielzahl von mit Öffnungen 4 versehenen Aufnahmebuchsen 5 derart nebeneinander symmetrisch zu der Längserstreckung der Leisten lin entsprechende Aussparungen (nicht dargestellt) eingesetzt, dass die Öffnungen 4 zu den Öffnungen 4 benachbarter Leisten 1fluchten. Die Aufnahmebuchsen 5 sind mit den Leisten 1jeweils fest verbunden. Entsprechend können die Aufnahmebuchsen 5 alternativ auch in den parallel zueinander verlaufenden Leisten 2 angeordnet sein.In this grid 3 are in mutually parallel bars 1 or 2, in Fig. 1 are the longer strips 1, a plurality of openings 4 provided with receiving sockets 5 so side by side symmetrically to the longitudinal extent of the strips lin corresponding recesses (not shown) used that the openings 4 to the openings 4 adjacent strips 1. The receiving sockets 5 are firmly connected to the strips 1 each. Accordingly, the receiving bushes 5 may alternatively be arranged in the mutually parallel strips 2.

Die Öffnungen 4 in den Aufnahmebuchsen 5 dienen der Aufnahme von in diese einschiebbaren Tragstäben 6, die sich jeweils über die gesamte Breite des Gitterrostes 3, d.h. durch jeweils sämtliche zueinander fluchtenden Aufnahmebuchsen 5, erstrecken. Durch die sich nun parallel durch den Gitterrost 3 erstreckenden Tragstäbe 6 wird eine deutlich bessere Stabilität des Gitterrostes 3, verbunden mit einer erhöhten Tragfähigkeit erreicht. Fig. 2 zeigt die Anordnung von mehreren sich parallel nebeneinander durch die Gitterroste 3, 3" erstreckenden Tragstäben 6.The openings 4 in the receiving bushes 5 are used to receive in this insertable support rods 6, each extending over the entire width of the grating 3, that is, by each mutually aligned receiving sockets 5, respectively. By now parallel through the grating 3 extending support rods 6 a significantly better stability of the grating 3, combined with an increased load capacity is achieved. Fig. 2 shows the arrangement of several parallel to each other through the gratings 3, 3 "extending support rods. 6

Grundsätzlich könnten Tragstäbe 6 auch direkt in entsprechend eingebrachte Aussparungen in den Leisten 1, 2 eingesetzt werden, jedoch wäre dadurch eine schlechtere Lastverteilung in Gitterrost 3 die Folge. Durch die Aufnahmebuchsen 5 wird eine sehr gute Lastverteilung im Gitterrost 3 erreicht.In principle, support rods 6 could also be used directly in correspondingly introduced recesses in the strips 1, 2, but this would result in a worse load distribution in the grid 3 the result. By receiving bushes 5 a very good load distribution in the grating 3 is achieved.

Die Tragstäbe 6 können selbstverständlich massiv ausgeführt sein, jedoch werden aus Gewichtsgründen und wegen der besseren Biegesteifigkeit rohrförmige Tragstäbe 6 bevorzugt.The support rods 6 can of course be made solid, but tubular weight bearing rods 6 are preferred for weight reasons and because of the better flexural rigidity.

Diese Tragstäbe 6 können aus Graphit oder CFC, oder auch aus Metall (Edelstahl, Aluminium o. dgl.) bestehen, da ein Kontakt zu den auf dem Gitterrost 3 befindlichenThese support rods 6 may be made of graphite or CFC, or even of metal (stainless steel, aluminum o. The like.) Exist, since a contact with those on the grate 3 located

(chargierten) Gegenständen, die einer Warmbehandlung unterzogen werden sollen, nicht möglich ist.(charged) objects that are to be subjected to a heat treatment is not possible.

Bereits durch die Ausstattung des Rostes 3 mit den Tragstäben 6 wird eine erheblich verbesserte Steifigkeit und Tragfähigkeit desselben erreicht.Already by equipping the grate 3 with the support rods 6 a significantly improved rigidity and load capacity of the same is achieved.

Mit den Tragstäben 6 besteht nun die einfache Möglichkeit, mehrere auch unterschiedlich große Gitterroste 3 zu größeren Elementen einfach und belastbar zusammenzufügen. Die Tragstäbe 6 erstrecken sich dabei jeweils durch zwei oder mehr benachbarte Gitterroste 3. In Fig. 2 sind zwei Gitterroste 3, 3' zusammengefügt. Die Tragstäbe 6 besitzen bevorzugt einen runden Querschnitt, können grundsätzlich jedoch auch andere Querschnitte aufweisen, wobei die Öffnungen 4 in den Aufnahmebuchsen 5 dann eine entsprechende Innenkontur aufweisen müssen.With the support rods 6, there is now the simple way to assemble several differently sized gratings 3 to larger elements easily and resiliently. The support rods 6 each extend through two or more adjacent gratings 3. In Fig. 2 are two gratings 3, 3 'joined together. The support rods 6 preferably have a round cross section, but in principle may also have other cross sections, wherein the openings 4 in the receiving bushes 5 then have to have a corresponding inner contour.

Um zu verhindern, dass der Verbund von zwei Gitterrosten 3 bei der Handhabung auseinander rutschen könnte, sollte der Außendurchmesser der Tragstäbe 6 und der Innendurchmesser der Öffnungen 4 in den Aufnahmebuchsen derart aufeinander abgestimmt sein, dass sich die Tragstäbe 6 straff, d. h. entgegen einer Friktionskraft, in die Öffnungen 4 einschieben lassen.In order to prevent the composite of two gratings 3 from slipping apart during handling, the outer diameter of the support rods 6 and the inner diameter of the openings 4 in the receptacles should be matched to one another such that the support rods 6 are taut, ie. H. against a friction force, can be inserted into the openings 4.

Fig. 3 zeigt eine Stapelanordnung mehrerer solcher Gitterroste 3, die mit Hilfe von modularen Abstandshaltern/Stützen 7 in einem vorgegebenen Abstand übereinander gestapelt sind. Die Abstandshalter/Stützen 7 sind jeweils in den Ecken der jeweiligen Gitterroste 3 formschlüssig in diese eingesetzt, so dass ein stabiler dreidimensionaler Verbund entsteht. Für die Aufnahme der Stützen 7 sind in den Ecken der Gitterroste 3 Führungen 11 vorgesehen, in die sich die Stützen 7 straff, also entgegen einer Friktion einsetzen lassen. Da die Führungen 11 einen quadratischen Querschnitt aufweisen, sollten die Enden der Stützen 7 eine entsprechende Außenkontur aufweisen. Um das zu erreichen, sind jeweils zwei äußere Leisten 1, 2 in einem entsprechenden engeren Abstand zueinander angeordnet, als die anderen Leisten des Gitterrostes 3. Auf diese Weise bilden sich die Führungen 11 mit quadratischem Querschnitt in den Ecken des Gitterrostes 3. Fig. 3 shows a stacking arrangement of a plurality of such gratings 3, which are stacked by means of modular spacers / supports 7 at a predetermined distance one above the other. The spacers / supports 7 are each inserted in the corners of the respective gratings 3 positively in this, so that a stable three-dimensional composite is formed. For the reception of the supports 7 3 guides 11 are provided in the corners of the gratings, in which the supports 7 can be taut, so use against a friction. Since the guides 11 have a square cross section, the ends of the Columns 7 have a corresponding outer contour. In order to achieve this, two outer strips 1, 2 are arranged at a corresponding closer distance to one another than the other strips of the grating 3. In this way, the guides 11 with a square cross section form in the corners of the grating 3.

Weiterhin ist jeder Gitterrost 3 an den Schmalseiten mit einer Verriegelung für die Leisten 1, 2 versehen, die jeweils aus einer äußeren Verriegelungsleiste 8 besteht (Fig. 1). Durch diese Verriegelungsleisten 8 erstrecken sich aus den Stirnseiten der längs verlaufenden Leisten 1 hervorstehende Zapfen 9, derart, dass diese aus der Verriegelungsleiste 8 hervorstehen. Die hervorstehenden Zapfen 9 sind jeweils mit einem Loch versehen, das mit den Löchern in den benachbarten Zapfen 9 fluchtet. Durch sämtliche Löcher ist ein Verriegelungsstab 10 mit rundem oder eckigem Querschnitt formschlüssig geschoben. Nur nach der Entfernung des Verriegelungsstabes 10 lässt sich das Gitterrost 3, 3' zwecks Reparatur o. dgl. auseinanderbauen.Furthermore, each grid 3 is provided on the narrow sides with a lock for the strips 1, 2, each consisting of an outer locking strip 8 ( Fig. 1 ). By this locking strips 8 extend from the end faces of the longitudinal strips 1 projecting pins 9, such that they protrude from the locking bar 8. The protruding pins 9 are each provided with a hole which is aligned with the holes in the adjacent pin 9. Through all holes a locking rod 10 is pushed with a round or square cross-section form fit. Only after the removal of the locking bar 10, the grid 3, 3 'for the purpose of repair o. The like. Disassemble.
