Description

Die vorliegende Erfindung betrifft eine Doppeldeckelschleuse zum Verschließen zweier aneinander anschließbarer Öffnungen beliebiger Querschnittsform, vorzugsweise zum Ankoppeln von Behältern für Schadstoffe an die Bodenöffnung eines Containments, mit einem, mittels einer Vorrichtung abhebbaren Abschlußdeckel der Bodenöffnung als Oberdeckel eines Doppeldeckelsystemes.The present invention relates to a double-lid lock for closing two openings that can be connected to each other any cross-sectional shape, preferably for coupling Containers for pollutants at the bottom opening of a containment, with a cover which can be lifted off by means of a device the bottom opening as the top cover of a double cover system.

Bei herkömmlichen Konstruktionen solcher Doppeldeckelschleusen werden zum Anheben des Verschlußdeckels Führungszylinder benötigt, um den Verschlußdeckel senkrecht von der Grundplatte aus seiner Dichtung abheben zu können, bevor er von einem Schwenkarm auf einer Kreisbahn weggeschwenkt wird. Dieser Bewegungsablauf ist erforderlich, um zum einen ein Verkanten des Verschlußdeckels im Flansch zu verhindern und zum anderen eine Zerstörung der Dichtung durch seitliches Reiben vor allem dann zu verhindern, wenn die Schwenkachse aus räumlichen Gründen nahe am Deckel sitzen muß.In conventional designs of such double-lid locks guide cylinders are required to lift the cover, around the cap vertically from the base plate to be able to lift off his seal before moving from a swivel arm is swung away on a circular path. This sequence of movements is necessary, on the one hand, to tilt the cover to prevent in the flange and the other one Destruction of the seal by rubbing on the side especially then to prevent when the pivot axis for spatial reasons must sit close to the lid.

Aus der EP-A-0 586 307 und der US-A-2 108 238 sind normale Verschlußdeckel bekannt, die um eine Achse auf eine Öffnung geschwenkt werden. Aus der US-A-4 932 160 und der US-A-1 688 570 sind senkrechte Deckel bekannt geworden, die an eine horizontale Öffnung geschwenkt werden. Da hierbei die Schwerkraft in der Deckelebene wirkt, sind die Druckkräfte beim Aufsetzen auf die Dichtung ganz andersartig als bei vertikalen Öffnungen. Letzlich ist aus der US-A-3 488 883 eine Schwenkvorrichtung für einen Deckel bekannt geworden, die einen, an einer Achse um diese schwenkbaren Schwenkbügel besitzt, an welchem der Abschlußdeckel um eine weitere, zu der Schwenkachse parallelen Achse an seiner, der Öffnung abgewendeten Seite kippbar angelenkt ist. EP-A-0 586 307 and US-A-2 108 238 are normal Closure cap known that around an axis on an opening be pivoted. From US-A-4 932 160 and US-A-1 688 570 vertical lids have become known, connected to a horizontal one Opening can be pivoted. Because this is gravity acts in the lid level, the compressive forces are when placing on the seal in a completely different way than with vertical openings. Ultimately, US-A-3,488,883 is a swivel device has become known for a lid, the one on one Has axis about this pivotable swivel bracket on which the end cover around another, to the pivot axis parallel axis on its side facing away from the opening is articulated tiltable.

Aufgabe der vorliegenden Erfindung ist es daher, eine neue Doppeldeckelschleuse anzugeben, bei welcher der Abschlußdeckel auf einfachere Weise aus den angeführten Gründen senkrecht in Bezug auf die Dichtung bzw. aus seinem Sitz abgehoben und in ihn wieder abgesenkt werden kann.The object of the present invention is therefore to create a new one Specify double-lid lock at which the end cover in a simpler way for the reasons given vertically in With respect to the seal or lifted out of its seat and in it can be lowered again.

Zur Lösung der Aufgabe schlägt die vorliegende Erfindung die Merkmale vor, die im kennzeichnenden Teil des Patentanspruches 1 angeführt sind. Weitere vorteilhafte Merkmale der Erfindung sind in den kennzeichnenden Merkmalen der Unteransprüche offenbart.To achieve the object, the present invention proposes Features before in the characterizing part of the claim 1 are listed. Further advantageous features of the invention are disclosed in the characterizing features of the subclaims.

Der Vorteil der vorliegenden Erfindung liegt neben dem genau senkrechten Abheben des Deckels vor allem darin, daß die Abmaße der Doppeldeckelschleuse durch die Verlegungsmöglichkeit der Schwenkachse direkt neben die Öffnung erheblich verringert werden können und daß die Öffnung beliebige, wie z. B. rechteckige oder quadratische Querschnittsform aufweisen kann.The advantage of the present invention is besides that vertical lifting of the lid especially in that the dimensions the double lid lock due to the possibility of laying the pivot axis directly next to the opening is significantly reduced can be and that the opening any such. B. can have a rectangular or square cross-sectional shape.

Weitere Einzelheiten der vorliegenden Erfindung werden im folgenden und anhand der Figuren 1 bis 3 näher erläutert. Es zeigen:

  • die Fig. 1 eine Draufsicht auf eine Doppeldeckelschleuse mit einem runden Deckel als Ausführungsbeispiel, wobei jedoch auch rechteckige, quadratische oder andere polygonale Formen der Öffnung und des Deckels möglich sind,
  • die Fig. 2 einen Schnitt entlang AA der Fig. 1 und
  • die Fig. 3 eine Ansicht in Richtung B der Fig. 1.
    • Further details of the present invention are explained in more detail below and with reference to FIGS. 1 to 3. Show it:
  • 1 is a plan view of a double-lid lock with a round lid as an exemplary embodiment, but rectangular, square or other polygonal shapes of the opening and the lid are also possible,
  • 2 shows a section along AA of FIGS. 1 and
  • 3 is a view in the direction B of FIG. 1st

    • Die Doppeldeckelschleuse dient dazu, die Beschickungsöffnung 1 im Bodenflansch 6 einer Grundplatte 2 eines nicht näher dargestellten Containmentes, in einem speziellen Anwendungsfall einer Arbeitsbox zum Umgang mit umweltschädlichen Stoffen, mittels der sogenannten Doppeldeckeltechnik zu verschließen. Die Beschickungsöffnung 1 einschließlich Bodenflansch 6 und Deckel kann dabei rund sein, jedoch auch andere Formen wie rechteckig oder quadratisch aufweisen.The double-cover lock serves to open the loading opening 1 in the bottom flange 6 of a base plate 2 of a not shown Containments, in a special application one Work box for handling environmentally harmful substances, by means of to close the so-called double-lid technology. The Feed opening 1 including bottom flange 6 and cover can be round, but also other shapes such as rectangular or square.

    Bei der Doppeldeckeltechnik werden die beiden Deckel von zwei miteinander zu verbindenden, nach außen dichten Behältnissen während des Ankoppelvorganges unter gegenseitiger Abdichtung ihrer Außenseiten miteinander verklammert. Bei diesem Vorgang werden die Behälter miteinander verbunden. Beide Deckel werden nach der Verklammerung zusammen in eines der beiden innenkontaminierten Behältnisse verbracht oder mit einer Vorrichtung aus der Öffnung ins Innere weggeschwenkt, wobei die einander gegenüberliegenden, inneren Flächen beider miteinader verklammerter Deckel immer unkontaminiert bleiben. Die Trennung der Deckel voneinander erfolgt entsprechend umgekehrt. Das heißt, nach der Trennung voneinander liegen die unkontaminierten Flächen der Deckel jetzt bei jedem Behältnis wieder außen. Bei der hier vorliegenden Doppeldeckelschleuse wird jedoch nur der eine, dem einen Behältnis zugeordnete und wegschwenkbare Deckel einer Doppeldeckelschleuse, betrachtet.In the double-lid technology, the two lids are replaced by two externally sealed containers to be connected to one another during the coupling process with mutual sealing their outer sides clamped together. In this process the containers are connected to each other. Both lids will after stapling together in one of the two internally contaminated Containers spent or with a device pivoted away from the opening into the interior, the each other opposite, inner surfaces of both clamped together Always keep the lid uncontaminated. The separation of the Lids from each other are reversed accordingly. This means, after separation from each other, the uncontaminated areas are located the lid on the outside of every container. At the double-lid lock here is only the one which is assigned to a container and can be pivoted away Lid of a double-lid lock, considered.

    Auf der in den Figuren dargestellten Grundplatte 2 ist der eine, hier Abschlußdeckel 3 des Containments genannte Deckel eines solchen Doppeldeckelsystemes über dem Bodenflansch 6 mittels der in den Lagerböcken 5 gelagerten Schwenkachse 4 in Schwenkrichtung 7 als Ganzes aus der Öffnung 1 wegschwenk- bzw. in sie absenkbar. Dabei soll die Schwenkachse 4 aus Gründen der Raumökonomie möglichst nahe an der Öffnung 1 liegen. An der, der Schwenkachse 4 gegenüberliegenden Seite des Doppeldeckelsystemes ist auf dem Flansch 6 eine Spannvorrichtung 19 mit Handgriff 20 befestigt, mit welcher der geschlossene Deckel an dem Joch 15 im geschlossenen Zustand in seine Dichtung gedrückt und zugehalten wird. Neben dieser Befestigungs- bzw. Verriegelungsartart des Deckels durch eine Spannvorrichtung mit Handgriff sind auch andersartige Verschließvorrichtungen mit elektrischem, hydraulischem oder pneumatischem Antrieb möglich. On the base plate 2 shown in the figures is the a cover, here called cover 3 of the containment of such a double lid system over the bottom flange 6 by means of the pivot axis 4 in which is supported in the bearing blocks 5 Swivel direction 7 as a whole swivel away from opening 1 or lowerable into it. The pivot axis 4 is intended for reasons the space economy as close as possible to the opening 1. On the side of the double cover system opposite the pivot axis 4 is a clamping device on the flange 6 19 attached with handle 20, with which the closed Cover on the yoke 15 in the closed state in its seal is pressed and held closed. In addition to this or type of locking of the cover by a clamping device other types of locking devices are also available with a handle with electric, hydraulic or pneumatic drive possible.

    Die Befestigung des Abschlußdeckels 3 an der Schwenkachse 4 erfolgt nun auf besondere Weise:The attachment of the end cover 3 on the pivot axis 4th now takes place in a special way:

    An der Schwenkachse 4 sind mit Abstand zwei Schwenkbügel 8 angeschweißt, an bzw. unter denen der Abschlußdeckel 3 in Verhältnis zu ihnen kippbar aufgehängt ist und die durch das Joch 15 verbunden sind. Dazu sind auf den Abschlußdeckel 3 an der, der Öffnung 1 abgewendeten Oberseite 12 weitere zwei Doppellagerböcke 9 mit auf der Achse 11 durchgehenden drehbaren Lagerbolzen 10 aufgesetzt, auf welchen wiederum die Schwenkbügel 8 befestigt sind. Der Abschlußdeckel 3 ist somit um die Achse 11 zusätzlich zu der Schwenkung um die Schwenkachse 4 kipp- bzw. drehbar. Die Achse 11 ist dabei, wie bereits erwähnt auf der Oberseite 12 bzw. der der Öffnung 1 abgewendeten Seite des Abschlußdeckels 3 gelegen.Two swivel brackets 8 are welded to the swivel axis 4 at a distance, at or below which the cover 3 in relation is tilted to them and hung by the yoke 15 are connected. For this purpose, on the end cover 3 on the The top 12 facing away from the opening 1 has a further two double bearing blocks 9 with rotatable bearing bolts on the axis 11 10 placed on which in turn the swivel bracket 8th are attached. The end cover 3 is thus about the axis 11 in addition to the pivoting about the pivot axis 4 rotatable. The axis 11 is, as already mentioned on the Top 12 or the side of the end cover facing away from the opening 1 3 located.

    An der Unterseite der Schwenkbügel 8 sind zwischen der Schwenkachse 4 und der Achse 11 eine oder mehrere Distanzschrauben 13 eingeschraubt, deren verstellbare Spitze 14 die Bewegung des Abschlußdeckels 3 gegen den Schwenkbügel 8 begrenzt. Weiterhin sind an der Unterseite der Schwenkbügel 8 im Bereich der Quertraverse 15 ein oder mehrere Zylinderstifte 16 befestigt, die in Richtung Deckel 3 ragen und auf welchen eine Feder 17 größerer Länge mit Überstand sitzt. Gegenüber dieser Feder 17 weist der Deckel 3 eine Ausnehmung 18 auf, in welche die Feder beim Anliegen des Deckels 3 an den Flansch 6 einragt.At the bottom of the swivel bracket 8 are between the Swivel axis 4 and axis 11 one or more spacing screws 13 screwed in, the adjustable tip 14 the Movement of the end cover 3 against the swivel bracket 8 limited. Furthermore, on the underside of the swivel bracket 8 in Area of the cross-beam 15 one or more cylindrical pins 16 attached, which protrude towards cover 3 and on which one Spring 17 of greater length sits with a protrusion. Opposite this Spring 17, the cover 3 has a recess 18 into which the spring protrudes when the cover 3 is in contact with the flange 6.

    Die Funktion der Doppeldeckelschleuse ist wie folgt:The function of the double-lid lock is as follows:

    Der Abschlußdeckel 3 wird mit einer nicht dargestellten Winde oder einer anderen Vorrichtung an den Schwenkbügeln 8 um die Achse 4 auf einem Kreisbogen hochgeschwenkt. Da der Deckel 3 gegenüber den Schwenkbügeln um die Achse 11 drehbar ist und dabei seine Lage zu diesen verändert, bewegt er sich ein Stück bis zum Anschlag an die Spitze 14 der Distanzschraube 13 und wird dann mitgeführt. In dieser Stellung wird er hochgeschwenkt und verbleibt so bis in die nicht dargestellte obere Schwenkposition. Beim Absenken in umgekehrter Richtung pendelt der Deckel 3 kurz vor dem Aufsetzen in die Öffnung 1 in horizontale Lage, wobei in diesem Moment die Feder 17 in der Ausnehmumg 18 zur Anlage kommt und nunmehr auf den in der Dichtung sitzenden Deckel drückt. Wird der Deckel 3 jetzt wieder angehoben, so verharrt er kurzzeitig unter dem Federweg der Feder 17 während des senkrechten Abhebens, ehe er dann wie oben beschrieben weggeschwenkt wird. The end cover 3 is with a winch, not shown or another device on the swivel bracket 8 around the Axis 4 swung up on an arc. Since the lid 3 is rotatable about the axis 11 relative to the swivel brackets and thereby changing its position to these, it moves a little until it stops at the tip 14 of the spacer screw 13 and is then carried along. In this position it is swiveled up and so remains in the upper, not shown Swivel position. Swings in the opposite direction when lowering the lid 3 shortly before placing in the opening 1 in horizontal Location, at which moment the spring 17 in the Ausnahmumg 18 comes to rest and now on the in the seal seated lid presses. Now the lid 3 is back raised, it remains briefly under the travel of the Spring 17 during the vertical lifting, before it then like is pivoted away as described above.
