Description

Die Erfindung betrifft eine rolladenartige Abdeckung für Montagegruben, mit den Merkmalen des Einleitungsteils von Patentanspruch 1.The invention relates to a roller shutter-like cover for assembly pits, with the features of the introductory part of claim 1.

Eine derartige Abdeckung ist aus den Unterlagen einer öffentlichen Ausschreibung betreffend den Neubau der Autobahnmeisterei Wels, Österreich bekannt. Bei der bekannten Abdeckung sind in die Enden der Tragbalken als Führungskörper Beschläge mit horizontalen Führungsnuten eingesetzt, mittels deren die Tragbalken an in diese Führungsnuten eingreifenden Führungsschenkeln der Schienen geführt sind. Diese Führungsschenkel führen die Tragbalken im vertikalen Bewegungsbahnabschnitt und tragen diese im bodenseitigen Bahnabschnitt. Im deckseitigen Bahnabschnitt verhindern die Führungsschenkel ein Aufbäumen der Abdeckung während diese in ihre Abdeckstellung geschoben wird. Aufgrund ausreichender Breite der Führungsnut haben die deckseitigen Führungsschenkel keine tragende Funktion.Such coverage is known from the documents of a public tender regarding the new construction of the Autobahnmeisterei Wels, Austria. In the known cover, fittings with horizontal guide grooves are used as guide bodies in the ends of the support beams, by means of which the support beams are guided on guide legs of the rails which engage in these guide grooves. These guide legs guide the supporting beams in the vertical movement path section and carry them in the bottom path section. In the sheet section on the deck side, the guide limbs prevent the cover from rearing up while it is pushed into its covering position. Due to the sufficient width of the guide groove, the cover-side guide legs have no supporting function.

Eine ähnliche Abdeckung, bei der die Tragbalken teleskopartig ein- und ausfahren können und an ihren Enden Rollen als Führungskörper aufweisen, ist aus der GB-A-2 060 754 bekannt. Die Achsen der Rollen verlaufen rechtwinklig zu den Tragbalken und stüzen sich an senkrechten Führungsschenkeln der deckseitigen Schienen ab. Die Rollen können ein Aufbäumen der geschobenen Abdeckung nicht verhindern und diese längs eines bodenseitigen Bahnabschnittes auch nicht tragen.A similar cover, in which the support beams can extend and retract telescopically and have rollers as guide bodies at their ends, is known from GB-A-2 060 754. The axes of the rollers run at right angles to the support beams and are supported on vertical guide legs of the rails on the deck. The rollers cannot prevent the pushed cover from rearing up and cannot carry it along a bottom-side web section.

In der DE-A-2 646 395 ist eine andere Abdekkung für Montagegruben beschrieben, wobei die Tragbalken ein Gliederband bilden und die Enden des Gliederbandes mittels über Umlenkrollen geführter Seile miteinander zu einer endlosen Anordnung verbunden sind. Der Antriebsmotor wirkt auf die Abdeckung in beiden Bewegungsrichtungen ziehend ein. Die Umlenkrollen erhöhen den Montageaufwand. Bei langer Montagegrube wird es schwierig, die Abdeckung in einzelne Teile zu unterteilen, was oft erwünscht ist.Another cover for assembly pits is described in DE-A-2 646 395, wherein the supporting beams form a link belt and the ends of the link belt are connected to one another in an endless arrangement by means of cables guided over deflection rollers. The drive motor pulls the cover in both directions of movement. The deflection rollers increase the assembly effort. With a long installation pit, it becomes difficult to divide the cover into individual parts, which is often desirable.

Im DE-U-1 940 275 ist eine Abdeckung beispielsweise für Schwimmbecken beschrieben, die schiebend bewegt werden soll, wobei die Abdekkung schwimmend ausgebildet ist und ohne besondere Führungen auskommt. Ein besonderer motorischer Antrieb ist nicht beschrieben.DE-U-1 940 275 describes a cover, for example for swimming pools, which is to be moved in a sliding manner, the cover being designed to be floating and requiring no special guides. A special motor drive is not described.

Aus der US-A-3 603 046 ist eine andere Abdeckung bekannt, die für eine Montagegrube gedacht ist. Die Abdeckung kann auf Führungen in Stellung gebracht werden.Another cover is known from US-A-3 603 046, which is intended for an assembly pit. The cover can be positioned on guides.

Es ist Aufgabe der Erfindung, die rolladenartige Abdeckung der eingangs beschriebenen Gattung hinsichtlich der Führung der Tragbalken zu vereinfachen.It is an object of the invention to simplify the roller shutter-like cover of the type described above with regard to the guidance of the supporting beams.

Diese Aufgabe wird durch die Merkmale des Kennzeichnungsteils von Patentanspruch 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Dank der Lagerung der Rollen auf den Bolzen der Kettengelenke entfallen jegliche stirnseitigen Beschläge an den Tragbalken. Die Rollen haben keine Lastaufnahmefunktion sondern nur eine Führungsfunktion. Sie vermeiden jede Verklemmungsgefahr. Dank der neuen Anordnung der Kettenräder wird diesen gleichzeitig eine Umlenkfunktion gegeben. Hierdurch wird die Bauweise wesentlich vereinfacht. Darüber hinaus wird der Vorteil gewonnen, daß die Schubkraft durch die angetriebenen Kettenräder geradlinig in den betreffenden Teil der Abdeckung eingeleitet wird. Dadurch werden von vorneherein etwaige Klemmkräfte vermindert.Thanks to the bearings of the rollers on the pins of the chain links, there is no need for any front fittings on the support beams. The roles have no load suspension function but only a management function. You avoid any risk of jamming. Thanks to the new arrangement of the sprockets, they are also given a deflection function. This significantly simplifies the construction. In addition, the advantage is gained that the thrust is introduced by the driven sprockets in a straight line in the relevant part of the cover. This reduces any clamping forces from the outset.

Wenn auf die Rollen keine Traglast einwirkt, die die Abdeckung in der Abdeckstellung aufnehmen muß, können diese Teile und die zugehörigen Führungen vergleichsweise leicht ausgebildet werden.If there is no load acting on the rollers, which the cover must accommodate in the cover position, these parts and the associated guides can be made comparatively light.

Mit den Merkmalen von Anspruch 4 werden die weiteren Vorteile erreicht, daß die Reibung während der Bewegung der Abdeckung weiter verringert und gleichzeitig eine Seitenführung der Abdekkung erreicht wird, wobei die Ketten an den Kunststoffauflagen geführt sind.With the features of claim 4, the further advantages are achieved that the friction during the movement of the cover is further reduced and at the same time a lateral guidance of the cover is achieved, the chains being guided on the plastic supports.

Figuren 1 und 2 zeigen Merkmale der Erfindung.Figures 1 and 2 show features of the invention.

Die Montagegrube 14 besitzt am oberen Rand Schienen in Doppel-T-Form, die fest eingemauert sind. Die Doppel-T-Schienen 11 tragen U-förmige Schienenführungen 10 für die Tragbalken 1, die beispielsweise von einem Rechteckrohr gebildet sind, und mit ihren Enden auf Kunststoffauflagen 28 (Fig. 2) aufliegen.The assembly pit 14 has rails in the double-T shape at the upper edge, which are firmly walled in. The double-T rails 11 carry U-shaped rail guides 10 for the supporting beams 1, which are formed, for example, by a rectangular tube and rest with their ends on plastic supports 28 (FIG. 2).

Die einzelnen Tragbalken 1 sind beim gezeigten Ausführungsbeispiel mittels abgewinkelter Befestigungselemente 21 (Fig. 2) an der Gelenkkette 2 befestigt. Diese Gelenkkette 2 besitzt Gelenkglieder, deren Länge der Tragbalkenbreite zuzüglich der Breite des Spaltes zwischen zwei Gelenkgliedern angepaßt ist. Das Kettengelenk 7 liegt jeweils unter diesem Spalt.In the exemplary embodiment shown, the individual supporting beams 1 are fastened to the articulated chain 2 by means of angled fastening elements 21 (FIG. 2). This articulated chain 2 has articulated links, the length of which is adapted to the width of the supporting beam plus the width of the gap between two articulated links. The chain link 7 is in each case under this gap.

Die Schubkraft zur Bewegung der Abdeckung 12 wird vom Antriebsmotor 4 über das obere Kettenrad 5 (Fig. 1) in die Gelenkkette 2 eingeleitet.The pushing force for moving the cover 12 is introduced into the link chain 2 by the drive motor 4 via the upper sprocket 5 (FIG. 1).

Mit 18 ist ein unteres Kettenrad bezeichnet Das Kettenrad besitzt hierfür entsprechende Ausnehmungen, die auf die Kettengelenke 7 einwirken. Wie FIG. 1 erkennen läßt, sind die Kettenräder 5 für die die Tragbalken verbindenden beiden Gelenkketten jeweils am Ende der Abdeckung angeordnet, wenn sich diese in der Abdeckstellung befindet. Wird die Abdeckung in Abdeckstellung gebracht, schiebt das Kettenrad 5 den in die Abdeckstellung einlaufenden Teil der Abdeckung vor sich her.With 18 a lower sprocket is designated. The sprocket has corresponding recesses that act on the chain links 7. As FIG. 1 reveals, the chain wheels 5 for the two link chains connecting the supporting beams are each arranged at the end of the cover when it is in the cover position. If the cover is brought into the cover position, the sprocket 5 pushes the part of the cover entering the cover position in front of it.

Da die Schubkraft genau in der Kettenebene eingeleitet wird, ergibt sich wenig Neigung zu einem Aufstellen der Kettenglieder, zumal die Höhenlage der Gelenkkette 2 weitgehend übereinstimmt mit der Höhenlage der Gleitfläche auf der Kunststoffauflage 28 (Fig. 2). Ergibt sich ein Widerstand und neigt ein Tragbalken zum Kippen, wird dies von der Rolle 8 verhindert. Im senkrechten Teil 19 der Führung und auch im Führungsteil auf dem Boden der Grube 14 kann auf eine Schiene für die Enden der Tragbalken 1 an sich verzichtet werden. Es empfiehlt sich jedoch, auch hier geeignete Schienenelemente, wenn auch geringerer Dimensionierung, mit sinngemäßer Auflage vorzusehen, um die Schiebebewegung auch in diesem Bereich sicher zu beherrschen.Since the thrust force is introduced exactly in the chain plane, there is little tendency to raise the chain links, especially since the height of the link chain 2 largely corresponds to the height of the sliding surface on the plastic support 28 (FIG. 2). If there is resistance and if a support beam tilts, this is prevented by the roller 8. In the vertical part 19 of the guide and also in the guide part on the bottom of the pit 14, there is no need for a rail for the ends of the supporting beams 1 per se. However, it is advisable to provide suitable rail elements, albeit of smaller dimensions, with a corresponding support, in order to be able to master the sliding movement in this area as well.

Gemäß Fig. 2 sind mittels der Schrauben 23 die Glieder 24 der Gelenkkette an der Unterseite der Tragbalken befestigt. Das Kettengelenk 7 wird jeweils von einem Bolzen 25 und einer Hülse 26 gebildet. Der Bolzen 25 trägt an seinem Ende die Rolle 8, welche an der Unterseite der Schiene 11 anliegt. Diese Schiene 11 bildet gleichzeitig den Stützflansch für die Enden der Balken 1. Auf diesem Stützflansch bzw. der Schiene 11 ist zu diesem Zweck mittels dar Schrauben 27 die Kunststoffauflage 28 aus einem geeigneten Kunststoff mit geringer Reibung montiert. Die Innenkante 29 der Kunststoffauflage 28 wirkt dabei mit der Außenkante 30 des Kettengliedes 24 zusammen, so daß auf diese Weise eine Führung des Tragbalkens 1 erhalten wird. Eine Winkelschiene begrenzt den Fußboden seitlich der Abdeckung der Montagegrube.2, the links 24 of the joint chain are fastened to the underside of the supporting beams by means of the screws 23. The chain link 7 is each formed by a pin 25 and a sleeve 26. The bolt 25 carries at its end the roller 8, which rests on the underside of the rail 11. This rail 11 also forms the support flange for the ends of the beams 1. For this purpose, the plastic support 28 made of a suitable plastic with low friction is mounted on this support flange or the rail 11 by means of the screws 27. The inner edge 29 of the plastic pad 28 cooperates with the outer edge 30 of the chain link 24, so that a guide of the support beam 1 is obtained in this way. An angle rail limits the floor to the side of the cover of the assembly pit.

Durch die Bauweise gemäß Fig. 2 wird die Herstellung der Grubenabdeckung wesentlich vereinfacht. Das ohnehin vorhandene Gelenk der Kette ist gleichzeitig auch die Achse der Rolle, wobei zwei benachbarte Rollen jeweils einen Tragbalken führen. Diese Bauweise hat weiter den Vorteil, daß für die Rollen keine U-förmigen Führungen notwendig sind. Es genügt, wenn die Rollen 8 einseitig an der Schiene 11 anliegen.2, the manufacture of the pit cover is considerably simplified. The already existing link of the chain is at the same time the axis of the roller, with two adjacent rollers each carrying a supporting beam. This design also has the advantage that no U-shaped guides are necessary for the rollers. It is sufficient if the rollers 8 bear on one side on the rail 11.

Bei dieser Ausführungsform der Erfindung liegen die Rollen von unten an der Schiene für die Balkenenden an. Dadurch wird erreicht, daß die Rollen bei einer etwaigen Belastung der Abdekkung. insbesondere beim Befahren durch ein Fahrzeug, nicht das Gewicht mittragen, und so einem Defekt ausgesetzt sind. Auch verringert sich so die Breite der Führung der Abdeckung, und es entsteht kein zusätzlicher Montageaufwand.In this embodiment of the invention, the rollers rest on the rail for the bar ends from below. This ensures that the rollers in the event of a possible load on the cover. especially when driving through a vehicle, do not carry the weight and are therefore exposed to a defect. This also reduces the width of the guide of the cover and there is no additional assembly effort.
