Abstract

A double-lidded lock for closing two openings of any cross-section which may be joined to each other, for example for coupling toxic material containers to the bottom opening of a containment, has a lid (3) for closing the bottom opening (1) which may be lifted by a device and which forms the top lid of a double-lidded closing system with one or several swivelling hoops (8) that can swivel around an axis (4). The closing lid (3) is hinged by its side opposite to the opening to the swivelling hoops (8) so as to swivel or tilt around another axis bolt (11) parallel to the swivelling axis bolt (4).

Description

Doppeldeckelschleuse zum Verschließen zweier aneinander anschließbarer ÖffnungenDouble-lid lock for closing two openings that can be connected to each other
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 Contain¬ ments, mit einem, mittels einer Vorrichtung abhebbaren Ab¬ schlußdeckel der Bodenöffnung als Oberdeckel eines Doppel- deckelsystemes.The present invention relates to a double-lid lock for closing two openings of any cross-sectional shape that can be connected to one another, preferably for coupling containers for pollutants to the bottom opening of a containment, with a closing lid of the bottom opening, which can be lifted off by means of a device, as the top lid of a double-lid system.
Bei herkömmlichen Konstruktionen solcher Doppeldeckelschleusen werden zum Anheben des Verschlußdeckels Führungszylinder benö¬ tigt, um den Verschlußdeckel senkrecht von der Grundplatte aus seiner Dichtung abheben zu können, bevor er von einem Schwenk¬ arm auf einer Kreisbahn weggeschwenkt wird. Dieser Bewegungs¬ ablauf ist erforderlich, um zum einen ein Verkanten des Ver¬ schlußdeckels 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 constructions of such double-cover locks, guide cylinders are required to lift the sealing cover in order to be able to lift the sealing cover vertically from the base plate out of its seal before it is pivoted away on a circular path by a pivoting arm. This sequence of movements is necessary, on the one hand, to prevent the sealing cover from tilting in the flange and, on the other hand, to prevent the seal from being destroyed by lateral rubbing, especially when the pivot axis must be close to the cover for spatial reasons.
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 provide a new double-cover lock in which the end cover can be lifted vertically with respect to the seal or from its seat and lowered again in a simpler manner for the reasons given.
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 of¬ fenbart.To achieve the object, the present invention proposes the features which are stated in the characterizing part of patent claim 1. 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 Ab¬ maße 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, in addition to the exactly vertical lifting of the cover, lies above all in the fact that the dimensions of the double-cover lock are possible due to the possibility of being laid the pivot axis right next to the opening can be significantly reduced and that the opening any such. B. may have a rectangular or square cross-sectional shape.
Weitere Einzelheiten der vorliegenden Erfindung werden im fol¬ genden und anhand der Figuren 1 bis 3 näher erläutert. Es zei¬ gen:Further details of the present invention are explained in more detail below and with reference to FIGS. 1 to 3. It shows:
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,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,
die Fig. 2 einen Schnitt entlang AA der Fig. 1 und2 shows a section along AA of FIGS. 1 and
die Fig. 3 eine Ansicht in Richtung B der Fig. 1.3 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 darge¬ stellten Containmentes, in einem speziellen Anwendungsfall ei¬ ner Arbeitsbox zum Umgang mit umweitschädlichen Stoffen, mit¬ tels 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 close the loading opening 1 in the bottom flange 6 of a base plate 2 of a containment (not shown in more detail), in a special application case of a work box for handling substances which are harmful to the environment, by means of the so-called double-cover technology. The loading opening 1 including the base flange 6 and cover can be round, but can also have 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 innenkon¬ taminierten Behältnisse verbracht oder mit einer Vorrichtung aus der Öffnung ins Innere weggeschwenkt, wobei die einander gegenüberliegenden, inneren Flächen beider miteinader verklam¬ merter Deckel immer unkontaminiert bleiben. Die Trennung der Deckel voneinander erfolgt entsprechend umgekehrt. Das heißt, nach der Trennung voneinander liegen die unkontaminierten Flä¬ chen 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 clamped together by two containers which are to be connected to one another and are sealed to the outside during the coupling process, with their outer sides being mutually sealed. In this process, the containers are connected to each other. After clipping, both lids are placed together in one of the two internally contaminated containers or swiveled away from the opening into the interior with a device, the mutually opposing inner surfaces of both lidded lids always remaining uncontaminated. The separation of the lids from one another is accordingly reversed. This means, after separation from one another, the uncontaminated surfaces of the lids are now on the outside of each container. In the case of the double-cover lock here, however, only the cover of a double-cover lock that is assigned to the container and can be swung away is 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 Grün¬ den der Raumökonomie möglichst nahe an der Öffnung 1 liegen. An der, der Schwenkachse 4 gegenüberliegenden Seite des Dop¬ peldeckelsystemes 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 Dich¬ tung gedrückt und zugehalten wird. Neben dieser Befestigungs¬ bzw. Verriegelungsartart des Deckels durch eine Spannvorrich¬ tung mit Handgriff sind auch andersartige Verschließvorrich¬ tungen mit elektrischem, hydraulischem oder pneumatischem An¬ trieb möglich.On the base plate 2 shown in the figures, the one, here called end cover 3 of the containment, of such a double cover system is pivoted above the base flange 6 by means of the pivot axis 4 mounted in the bearing blocks 5 in the pivoting direction 7 as a whole out of the opening 1 or into it lowerable. For reasons of space economy, the pivot axis 4 should lie as close as possible to the opening 1. On the side of the double cover system which is opposite the pivot axis 4, a clamping device 19 with a handle 20 is fastened on the flange 6, with which the closed cover on the yoke 15 is pressed into its seal and locked in the closed state. In addition to this type of fastening or locking of the cover by means of a tensioning device with a handle, other types of closing devices with electric, hydraulic or pneumatic drives are also possible.
Die Befestigung des Abschlußdeckels 3 an der Schwenkachse 4 erfolgt nun auf besondere Weise:The end cover 3 is now attached to the pivot axis 4 in a special way:
An der Schwenkachse 4 sind mit Abstand zwei Schwenkbügel 8 an¬ geschweißt, an bzw. unter denen der Abschlußdeckel 3 in Ver¬ hältnis 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 Doppella¬ gerböcke 9 mit auf der Achse 11 durchgehenden drehbaren Lager¬ bolzen 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 Ab¬ schlußdeckels 3 gelegen.Two swivel brackets 8 are welded to the swivel axis 4 at a distance, on or under which the end cover 3 is suspended in relation to them and which are connected by the yoke 15. For this purpose, on the top cover 3 on the top 12 facing away from the opening 1, two further double bearing blocks 9 with rotatable bearing bolts 10 passing through the axis 11 are placed, on which in turn the swivel brackets 8 are fastened. The end cover 3 can thus be tilted or rotated about the axis 11 in addition to the pivoting about the pivot axis 4. The axis 11 is, as already mentioned on the Upper side 12 or the side of the end cover 3 facing away from the opening 1.
An der Unterseite der Schwenkbügel 8 sind zwischen der Schwenkachse 4 und der Achse 11 eine oder mehrere Distanz¬ schrauben 13 eingeschraubt, deren verstellbare Spitze 14 die Bewegung des Abschlußdeckels 3 gegen den Schwenkbügel 8 be¬ grenzt. 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 ein¬ ragt.On the underside of the swivel bracket 8, one or more spacer screws 13 are screwed in between the swivel axis 4 and the axis 11, the adjustable tip 14 of which limits the movement of the end cover 3 against the swivel bracket 8. Furthermore, one or more cylindrical pins 16 are fastened to the underside of the swivel bracket 8 in the region of the crossbar 15 and project in the direction of the cover 3 and on which a spring 17 of greater length sits with a projection. Compared to 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 hochge¬ schwenkt 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 hori¬ zontale Lage, wobei in diesem Moment die Feder 17 in der Aus- nehmumg 18 zur Anlage kommt und nunmehr auf den in der Dich¬ tung 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. Bezuσszeichenliste:The end cover 3 is pivoted up with a winch, not shown, or another device on the swivel brackets 8 about the axis 4 on a circular arc. Since the cover 3 can be rotated about the axis 11 with respect to the swivel brackets and thereby changes its position relative to it, it moves a short distance to the tip 14 of the spacer screw 13 and is then carried along. In this position it is swiveled up and remains in the upper swivel position, not shown. When lowering in the opposite direction, the cover 3 swings in a horizontal position shortly before being placed in the opening 1, at which moment the spring 17 comes to rest in the recess 18 and now on the cover seated in the seal presses. If the cover 3 is now raised again, it remains briefly under the spring travel of the spring 17 during vertical lifting, before it is then pivoted away as described above. Reference list:
