Description

Die Erfindung betrifft eine Vorrichtungzum Umlegen und Drehen von Koksofentüren zum Zwecke der Wartung und Reparatur gemäß Oberbegriff des Hauptanspruches.The invention relates to a device for flipping and turning coke oven doors for the purpose of maintenance and repair according to the preamble of the main claim.

Aus der Literatur sind im wesentlichen 3 Arten von Türumlegeeinrichtungen bekannt. Bei einer ersten Art (vgl. z. B. die DE-PS-975 016 und die DE-OS-3 044 849) wird die Koksofentür von der Türabhebevorrichtung an das freie Ende der Koksofenbatterie gebracht und dort zunächst in einen senkrecht aufgestellten Rahmen eingehängt. Der Rahmen mit der Tür wird dann an einem Seilzug auf Horizontalschienen herabgelassen und dann nach dem Überholen der Tür in entsprechender Weise wieder aufgerichtet. Solche Vorrichtungen, an denen die tonnenschweren Türen mittels Seilzügen auf und ab bewegt werden, sind wie immer bei dem Transport von schweren Lasten an Seilzügen erfahrungsgemäß nicht betriebs- und unfallsicher.Essentially 3 types of door transfer devices are known from the literature. In a first type (cf., for example, DE-PS-975 016 and DE-OS-3 044 849) the coke oven door is brought from the door lifting device to the free end of the coke oven battery and is initially hung there in a vertically positioned frame . The frame with the door is then lowered on a cable on horizontal rails and then raised again after the door has been overhauled in a corresponding manner. Such devices, on which the doors weighing several tons are moved up and down by means of cables, are, as always, not operationally and accident-proof when transporting heavy loads on cables.

Die zweite Art von Umlegeeinrichtungen ist auf einem eigenen auf der Bedienungsbühne der Verkokungsofenbatterie verfahrbaren Wagen angeordnet, wobei die Kipp- und Dreheinrichtungen mittels einer Reihe von Hydraulikzylindern betätigt werden. Auch hierbei wird das obere freie Ende der Kipp- und Drehrahmen ohne weitere Führung auf und ab geschwenkt und gedreht. Insbesondere bei heute üblichen Ofentüren von 7 und mehr Meter Länge ergeben sich sehr hohe Drehmomente. Das führt dazu, daß die Vorrichtung äußerst stabil und damit sehr aufwendig ausgeführt werden muß. Außerdem bringt das Schwenken des freien Endes der Haltevorrichtung für das Bedienungspersonal auf der Ausfahrbühne erhebliche Gefahren mit sich.The second type of transfer device is arranged on its own carriage which can be moved on the operating platform of the coking furnace battery, the tilting and rotating devices being actuated by means of a series of hydraulic cylinders. Here, too, the upper free end of the tilting and rotating frame is pivoted up and down and rotated without further guidance. Particularly with today's conventional oven doors of 7 and more meters, there are very high torques. The result of this is that the device must be designed to be extremely stable and therefore very expensive. In addition, the pivoting of the free end of the holding device for the operating personnel on the extension platform entails considerable dangers.

Diese Umlegevorrichtungen mit Hydraulikzylindern sind u. a. in der DE-PS-2 142 706 und in dem Gebrauchsmuster 1 753 229 beschrieben.These transfer devices with hydraulic cylinders are u. a. in DE-PS-2 142 706 and in utility model 1 753 229.

Schließlich ist aus der DE-AS-1 177 600 eine Türumlegevorrichtung mit zwangsläufiger Führung des Tragrahmens mit Rollen bekannt, die in einem aus einem lotrechten und einem waagerechten Schienenpaar und einem diese miteinander verbindenden Übergangsschienenpaar bestehenden Führungsgestell geführt sind. Hierbei wird der Tragrahmen bei lotrechter Stellung an seinem oberen Ende mit Führungsrollen versehen und sein unteres Ende wird gelenkig mit einem auf einem parallel zum waagerechten Schienenpaar des Drehgestells angeordneten Gleis verfahrbaren Wagen verbunden. Zusätzlich ist neben diesem Wagen noch ein eigener Antriebswagen vorgesehen, der jeweils an- und abgekoppelt werden muß und ebenfalls auf dem unteren Gleis verfahrbar ist. Für Reparaturzwecke wird dabei außerdem eine eigene Hebevorrichtung benötigt, mit der der Rahmen und die darin befindliche Ofenfür in waagerechter Lage angehoben werden kann. Zur Drehung der Tür in dieser Lage müssen jeweils eigene Drehzapfen montiert werden.Finally, from DE-AS-1 177 600 a door folding device with positive guidance of the support frame with rollers is known, which are guided in a guide frame consisting of a vertical and a horizontal pair of rails and a connecting rail pair connecting them. In this case, the support frame is provided with guide rollers at its upper end in the vertical position and its lower end is articulated to a carriage which can be moved on a track arranged parallel to the horizontal pair of rails of the bogie. In addition to this car, there is also a separate drive car, which must be coupled and uncoupled and can also be moved on the lower track. A separate lifting device is also required for repair purposes, with which the frame and the furnace located therein can be raised in a horizontal position. To turn the door in this position, separate pivots must be installed.

Aufgabe der Erfindung ist es nun, eine unfallsichere Umlegevorrichtung zu schaffen, bei der ein aufwendiges An- und Abkuppeln der Antriebswagen entfällt und auf der Arbeitsbühne genügend Platz für Reparaturzwecke zur Verfügung steht. Darüberhinaus soll die aufwendige zusätzliche Hebe- und Drehvorrichtung entfallen.The object of the invention is now to provide an accident-proof transfer device in which there is no need for complex coupling and uncoupling of the drive car and there is sufficient space on the work platform for repair purposes. In addition, the complex additional lifting and turning device should be omitted.

Zur Lösung dieser Aufgabe wird vorgeschlagen, daß das Führungsgestell in der Mitte zwischen dem Führungsgestell auf der Koksseite und dem Führungsgestell auf der Maschinenseite unterbrochen ist und die Schienenpaare unten in stabilen Stopps fur die Führungsrollen enden und daß die Antriebsvorrichtung auf einer waagerechten, hochgelegenen Schienenfahrbahn verfahrbar ist.To solve this problem, it is proposed that the guide frame is interrupted in the middle between the guide frame on the coke side and the guide frame on the machine side and the pairs of rails end below in stable stops for the guide rollers and that the drive device can be moved on a horizontal, elevated rail track .

Gemäß der erfindungsgemäßen Ausführung ist zunächst für eine unfallsichere Umlegevorrichtung mit zwangsläufiger Führung des Tragrahmens gesorgt. Im Gegensatz zum Stand der Technik ist das Führungsgestell im waagerechten Bereich auf der Arbeitsbühne nicht durchgezogen, sondern unterbrochen. Wenn also der Tragrahmen mit der darin eingesetzten Koksofentür in die waagerechte Lage auf der Arbeitsbühne gebracht worden ist, können die Bedienungsmänner ohne Behinderung durch Führungsgestell und Schienen an der Tür arbeiten. Der Tragrahmen hängt an der einen Seite an der hochgelegenen waagerecht verfahrbaren Antriebsvorrichtung und wird bei waagerechter Lage über der Arbeitsbühne an den unteren Stopps des Führungsgestelles gehalten. Die Antriebsvorrichtung bleibt auch in senkrechter Stellung des Tragrahmens immer mit diesem verbunden. Ein An- und Abkuppeln der Antriebsvorrichtung von den Tragrahmen ist somit nicht erforderlich.According to the embodiment of the invention, an accident-proof folding device with an inevitable guidance of the support frame is initially provided. In contrast to the prior art, the guide frame is not pulled through in the horizontal area on the work platform, but rather interrupted. So if the support frame with the coke oven door inserted in it has been brought into the horizontal position on the work platform, the operators can work on the door without hindrance by the guide frame and rails. The support frame hangs on one side on the horizontally movable drive device and is held at the lower stops of the guide frame when it is in a horizontal position above the work platform. The drive device always remains connected to the support frame even in the vertical position. A coupling and uncoupling of the drive device from the support frame is therefore not necessary.

Die Erfindung sieht weiterhin vor, daß die Antriebsvorrichtung auf der waagerechten, hochgelegenen Schienenfahrbahn über Gegendruckrollen abgestützt ist und die Kettenräder des Antriebs in Rollenketten eingreifen, die unterhalb und/oder oberhalb der waagerechten Schienenfahrbahn der Antriebsvorrichtung angeordnet sind. Die Antriebsvorrichtung ist also auf der Schienenfahrbahn zwangsweise geführt und gegen ein Abkippen bei wechselnden Belastungsfällen geschützt.The invention further provides that the drive device is supported on the horizontal, high-lying rail track via counter-pressure rollers and the chain wheels of the drive engage in roller chains which are arranged below and / or above the horizontal rail track of the drive device. The drive device is therefore forcibly guided on the railroad track and protected against tipping over under changing load cases.

Es hat sich erfindungsgemäß als günstig erwiesen, daß an dem freien Ende des Tragrahmens, an dem er mit dem Ausleger verbunden ist, ein Drehantrieb mit Bremseinrichtung zur Drehung der im Tragrahmen gehaltenen Tür in jede beliebige Winkelstellung angeordnet ist. Es ist zwar aus der DE-PS-975 016 bekannt, den Türrahmen auch in waagerechter Stellung längsaxial drehbar auszubilden, wie diese Drehung in waagerechter Richtung ausgeführt werden soll, ist aber dort nicht beschrieben. Wegen der unsymetrischen Anordnung der Ofentür in dem Tragrahmen ist aber eine Drehung von Hand in waagerechter Richtung kaum möglich, so daß man in der Vergangenheit immer die Tür in senkrechter Stellung entsprechend gedreht hat und dann umgelegt hat. Zur Änderung der Stellung war es dann üblich, die Tür samt Türrahmen zunächst wieder in die senkrechte Stellung zu bringen, dort entsprechend zu drehen und dann wiederum abzusenken. Mit Hilfe des Vorschlags der Erfindung ist es möglich, die Tür in jede beliebige Winkelstellung auch in waagerechter Richtung zu drehen, ohne daß Tragrahmen und Tür zunächst wieder in die senkrechte Stellung gebracht werden müssen.It has proven to be advantageous according to the invention that a rotary drive with a braking device for rotating the door held in the support frame is arranged in any angular position at the free end of the support frame at which it is connected to the boom. It is known from DE-PS-975 016 to design the door frame to be axially rotatable in a horizontal position, such as this rotation in a horizontal direction Direction is to be carried out, but is not described there. Because of the asymmetrical arrangement of the oven door in the support frame, however, rotation by hand in a horizontal direction is hardly possible, so that in the past the door was always turned in a vertical position and then flipped. To change the position, it was then customary to first bring the door and the door frame back into the vertical position, turn it there accordingly and then lower it again. With the help of the proposal of the invention, it is possible to rotate the door in any angular position in the horizontal direction, without having to first bring the support frame and door back into the vertical position.

In diesem Zusammenhang sieht die Erfindung auch vor, daß der Tragrahmen bei waagerechter Stellung so hoch über der Arbeitsbühne angeordnet ist, daß er bei eingehängter Tür frei um die gesamte waagerechte Längsachse drehbar ist. Zur Entfernung von schweren Teilen des Türkörpers oder des Türstopfens kann nun die Tür so gedreht werden, daß die entsprechenden Teile senkrecht nach unten auf die Arbeitsbühne fallen.In this context, the invention also provides that the support frame is arranged so high above the work platform in the horizontal position that it can be freely rotated about the entire horizontal longitudinal axis when the door is suspended. To remove heavy parts of the door body or the door plug, the door can now be turned so that the corresponding parts fall vertically down onto the work platform.

Eine erhebliche Verbesserung der Unfallsicherheit wird auch dadurch gegeben, daß die waagerechte Schiene fahrbar oberhalb der waagerechten Stellung des Tragrahmens angeordnet ist und zwar mindestens so hoch, daß der auf der Arbeitsbühne stehende Bedienungsmann darunter ausreichende Kopffreiheit hat. Im Gegensatz zu den bekannten Vorrichtungen bei denen die Antriebswagen auf eigenen Schienen auf der Arbeitsbühne verfahren wurden, ist hierbei die Antriebsvorrichtung und die zugehörige Schienenfahrbahn entsprechend hoch über der Arbeitsbühne (vorzugsweise etwa 1,8 bis 3 m) angeordnet.A significant improvement in accident safety is also provided in that the horizontal rail is arranged to be movable above the horizontal position of the support frame and at least so high that the operator standing on the work platform has sufficient headroom underneath. In contrast to the known devices in which the drive cars were moved on their own rails on the work platform, the drive device and the associated rail carriageway are arranged correspondingly high above the work platform (preferably about 1.8 to 3 m).

Wenn man bei den bisher vorhandenen Umlegevorrichtungen die Tür nach Einsetzen in den Tragrahmen durch die Türanhebevorrichtung an der Bedienungsmaschine hydraulisch oder mittels Seilwinde umgelegt hat, bestand bisher die Notwendigkeit, daß die Tür für bestimmte Reparaturarbeiten mit eigenen Hebevorrichtungen etwa einen halben bis einen Meter wieder angehoben werden mußte. Diese eigene Hebevorrichtung ist dann nicht erforderlich, wenn man, wie erfindungsgemäß vorgeschlagen wird, die waagerechte Schienenfahrbahn für die Antriebsvorrichtung an den beiden Enden in der Endstellung jeweils schräg auf die von der Türabhebevorrichtung bzw. der Ebene der Ofensohle vorgegebene Höhe abfallen läßt. Nach Einsetzen der Tür in den senkrecht stehenden Tragrahmen fährt dabei die Antriebsvorrichtung zunächst die Schräge empor und bringt die Tür auf die entsprechende Arbeitshöhe und verfährt dann auf der waagerechten Schienenfahrbahn soweit zur Mitte hin, bis die oberen Führungsrollen des Tragrahmens an den unteren Stopps des Führungsgestells anliegen.If, in the case of the existing folding devices, the door was hydraulically or by means of a winch after being inserted into the supporting frame by the door lifting device on the operating machine, there was previously a need for the door to be raised about half a meter to one meter again for specific repair work with its own lifting devices had to. This own lifting device is not necessary if, as is proposed according to the invention, the horizontal rail track for the drive device at the two ends in the end position in each case slopes down to the height specified by the door lifting device or the level of the furnace sole. After inserting the door into the vertical support frame, the drive device first raises the incline and brings the door to the appropriate working height and then moves on the horizontal rail track to the center until the upper guide rollers of the support frame lie against the lower stops of the guide frame .

Die Verbindung zwischen Antriebsvorrichtung und dem Tragrahmen ist erfindungsgemäß derart ausgeführt, daß die Antriebsvorrichtung über einen rechtwinkligen Ausleger mit dem unteren Ausleger des Tragrahmens verbunden ist, wobei der waagerechte Schenkel des Auslegers an seinem freien Ende an der Antriebsvorrichtung gelenkig gelagert ist und sich im Knickpunkt über Führungsrollen auf der hochgelegenen Schienenfahrbahn abstützt und an dem freien Ende des senkrecht nach unten gerichteten Schenkels des Auslegers der Tragrahmen gelenkig eingehängt ist. Durch die rechtwinklige Ausführung des Auslegers mit dem senkrecht nach unten gerichteten Schenkel, an dem das Ende des Tragrahmens hängt, wird der erforderliche Spielraum zwischen Schienenfahrbahn und Tragrahmen sowie die erforderliche Kopffreiheit für den Bedienungsmann geschaffen. Durch die gelenkige Lagerung am unteren Auslegerende und der unteren Traverse kann während des Verfahrens der Antriebsvorrichtung der Tragrahmen nach oben oder unten schwenken, entsprechend dem Ablauf der Führungsrollen an den Flachschienen im Führungsgestell.The connection between the drive device and the support frame is designed according to the invention in such a way that the drive device is connected to the lower arm of the support frame via a right-angled arm, the horizontal leg of the arm being articulated at its free end on the drive device and at the break point via guide rollers supported on the elevated rail track and the support frame is hinged to the free end of the leg of the jib which is directed vertically downwards. The right-angled design of the boom with the vertically downward leg, on which the end of the support frame hangs, creates the required clearance between the rail track and the support frame as well as the required headroom for the operator. Due to the articulated mounting on the lower end of the boom and the lower traverse, the support frame can pivot up or down during the movement of the drive device, in accordance with the sequence of the guide rollers on the flat rails in the guide frame.

Insbesondere zur Erhöhung der Sicherheit während des Betriebes wird weiterhin vorgeschlagen, daß im oberen Bereich des Führungsgestells, an dem der Türabhebevorrichtung abgekehrten Ende eine Gegendruckschiene angeordnet ist, die ein Abkippen des Tragrahmens in der senkrechten Stellung verhindern soll.In particular, to increase safety during operation, it is further proposed that a counter pressure rail is arranged in the upper region of the guide frame, at the end remote from the door lifting device, which is intended to prevent the support frame from tipping over in the vertical position.

Beschreibung der Figuren 1 bis 3Description of Figures 1 to 3

Aus der Figur 1 ist die Vorrichtung zum Umlegen und Drehen von Koksofentüren dargestellt, so wie sie auf der Arbeitsbühne 5 am Ende einer Koksofenbatterie angeordnet ist. Sowohl auf der Koksseite KS als auch auf der Maschinenseite MS befindet sich je ein Führungsgestell mit dem senkrechten Teil 30 und dem schrägen Teil 32 sowie den unteren Stopps 34 und der Stütze 31, die auf der Arbeitsbühne steht. Das obere Ende des Führungsgestelles ist an der oberen Bühne 37 befestigt. In der Figur 1 ist weiterhin beispielhaft der Tragrahmen 21 und die Antriebsvorrichtung 10 für die Türen auf der Koksseite der Batterie in senkrechter Stellung des Tragrahmens dargestellt. Der Tragrahmen 21 für die Türen der Maschinenseite der Koksofenbatterie ist mit einer eingesetzten Tür 7 samt Türstopfen 8nd und Türkörper 9 in waagerechter Stellung dargestellt.From Figure 1, the device for flipping and turning coke oven doors is shown, as it is arranged on the work platform 5 at the end of a coke oven battery. Both on the coke side KS and on the machine side MS there is a guide frame with the vertical part 30 and the inclined part 32 as well as the lower stops 34 and the support 31, which stands on the work platform. The upper end of the guide frame is attached to the upper stage 37. In Figure 1, the support frame 21 and the drive device 10 for the doors on the coke side of the battery is shown in the vertical position of the support frame by way of example. The support frame 21 for the doors of the machine side of the coke oven battery is shown with an inserted door 7 together with the door plug 8nd and the door body 9 in a horizontal position.

Das obere Ende 23 des Tragrahmens 21 ist mit den Führungsrollen 22 bei den unteren Stopps 34 dargestellt. Das andere Ende 24 des dargestellten maschinenseitigen Tragrahmens 21 hängt am Ende 18 des senkrechten Auslegerteils 16. Der Ausleger ist im wesentlichen rechtwinklig ausgeführt, wobei der waagerechte Teil 15 des Auslegers oberhalb der Schienenfahrbahn 1 der Antriebsvorrichtung 10 angeordnet ist. Im Knickpunkt des Auslagers befinden sich Führungsrollen 19, die sich auf der Schienenfahrbahn 1 bewegen. Der Ausleger 15 bis 18 ist am Ende 17 gelenkig mit der Antriebsvorrichtung 10 verbunden. Diese Antriebsvorrichtung besteht aus dem Fahrgestell 12, das sich auf 4 Rollen auf der Schienenfahrbahn 1 bewegt, aus einem Aufsteckgetriebemotor 11, der am Fahrgestell 12 hängend montiert ist und über eine durchgehende Welle zwei Kettenräder 14 antreibt. Beim Verfahren der Antriebsvorrichtung 10 greifen die Kettenräder 14 in die unterhalb der Fahrbahn angeordnete Rollenkette 6 ein und erzeugen so die erforderlichen Druck- und Zugkräfte. Die im Knickpunkt des Auslegers angeordneten Führungsrollen 19 sind über nicht dargestellte Pufferfedern am waagerechten Auslegerteil 15 befestigt, so daß der Stoß beim Aufsetzen der Ofentür in den Tragrahmen gedämpft wird, sowie geringe Höhendifferenzen in der Fahrbahn ausgeglichen werden können. Am unteren Ende 18 des Auslegers sind -, hier ebenfalls nicht dargestellt -, zwei Lager angeschraubt. In diese Lager sind Schwenkzapfen der unteren Traverse 24 des Tragrahmens 21 eingeführt. Die beim Verfahren der Antriebsvorrichtungen an den Lagern am Ende 18 des Auslegers wirkende Druckkraft erzeugt über das Führungsrollenpaar 19 als Drehpunkt eine Hubkraft am Ende 17 des Auslegers. Um dieser Hubkraft entgegenzuwirken, sind unterhalb der Schienenfahrbahn 1 am Fahrgestell 12 zwei Gegendruckrollen 13 angebracht. Diese Gegendruckrollen laufen während der Fahrt der Antriebsvorrichtung an Flachschienen unterhalb der Schienenfahrbahn entlang.The upper end 23 of the support frame 21 is shown with the guide rollers 22 at the lower stops 34. The other end 24 of the illustrated machine-side support frame 21 hangs on the end 18 of the vertical boom part 16. The boom is essentially rectangular, the horizontal part 15 of the boom being arranged above the rail track 1 of the drive device 10. At the break point of the delivery there are guide rollers 19 which move on the rail track 1. The boom 15 to 18 is articulated at the end 17 to the drive device 10. This drive device consists of the chassis 12, which moves on 4 rollers on the rail track 1, of a slip-on geared motor 11, which is suspended from the chassis 12 and drives two chain wheels 14 via a continuous shaft. When the drive device 10 is moved, the chain wheels 14 engage in the roller chain 6 arranged below the roadway and thus generate the required compressive and tensile forces. The guide rollers 19 arranged at the bend point of the boom are fastened to the horizontal boom part 15 via buffer springs (not shown), so that the impact is dampened when the furnace door is placed in the supporting frame, and small differences in height in the roadway can be compensated for. At the lower end 18 of the boom, two bearings are screwed, also not shown here. In this camp pivot pin of the lower cross member 24 of the support frame 21 are inserted. The pressure force acting on the bearings at the end 18 of the boom when the drive devices are moved generates a lifting force at the end 17 of the boom via the pair of guide rollers 19 as the fulcrum. In order to counteract this lifting force, two counter pressure rollers 13 are attached to the chassis 12 below the rail track 1. These counter pressure rollers run along the flat rails below the rail track while the drive device is traveling.

Die Schienenfahrbahn 1, auf der die Antriebsvorrichtung 10 zusammen mit dem Ausleger hin und her bewegt wird, besteht aus zwei symetrischen Rahmen, die mit je zwei Stützen 4 von ca. 2 m Höhe auf der Arbeitsbühne befestigt sind. Die Höhe der Stützen wurde so groß gewählt, um die Fahrbahn aus dem Arbeitsbereich zu entfernen und so eine sehr gute Zugänglichkeit der waagerecht angeordneten Tür 7 zu erreichen. Auf der Oberseite der Schienenfahrbahn ist eine Flachschiene aufgeschweißt, als Fahrbahn für die beiden Antriebsvorrichtungen auf der Maschinen- und Koksseite. Auf der Unterseite der Schienenfahrbahn 1 zwischen den beiden Stützen 4 ist je eine Rollenkette 6 befestigt und verspannt, in die die Kettenräder 14 der Antriebsvorrichtung eingreifen und so die erforderlichen Druck- und Zugkräfte erzeugen. Außerdem ist auf der Unterseite eine Flachschiene angeschweißt, an der die Gegendruckrollen 13 abrollen. Die Schienenfahrbahn ist an den beiden Enden 2 nach unten abgeschrägt bzw. abgekröpft und besitzt am Ende eine stabile Stopvorrichtung 3. Die Abschrägung ermöglicht es, den Tragrahmen mit dem Auflagebock 28 (vgl. Fig. 3) für die Ofentür 7 auf die Höhenquote der Ofensohle zu bringen und andererseits beim Verfahren in die horizontale Lage den Tragrahmen 21 mit der Ofentür so weit anzuheben, daß genügend Spiel zwischen Arbeitsbühne 5 und Tragrahmen 21 entsteht, um ein Drehen des Rahmens mit der eingesetzten Ofentür in der horizontalen Lage zu ermöglichen. Die Stopps 3 am Ende der Schienenfahrbahn verhindern ein Überfahren der Endstellungen.The rail track 1, on which the drive device 10 is moved back and forth together with the boom, consists of two symmetrical frames, each of which is fastened to the work platform with two supports 4 of approximately 2 m in height. The height of the supports was chosen to be large enough to remove the roadway from the work area and thus achieve very good accessibility to the horizontally arranged door 7. A flat rail is welded onto the top of the rail track as a track for the two drive devices on the machine and coke sides. On the underside of the rail track 1 between the two supports 4, a roller chain 6 is fastened and clamped, in which the chain wheels 14 of the drive device engage and thus generate the necessary compressive and tensile forces. In addition, a flat rail is welded onto the underside, on which the counter pressure rollers 13 roll. The rail track is chamfered or cranked down at both ends 2 and has a stable stop device 3 at the end. The chamfer makes it possible to support the support frame with the support bracket 28 (see FIG. 3) Bring the oven door 7 to the level of the sole of the oven and, on the other hand, raise the support frame 21 with the oven door so far in the process in the horizontal position that sufficient play is created between the work platform 5 and the support frame 21 in order to rotate the frame with the oven door used in the horizontal Location. The stops 3 at the end of the rail track prevent the end positions from being passed.

Im oberen Bereich des Führungsgestells 30 sind Gegendruckschienen 35 vorgesehen, die ein Abkippen des Tragrahmens in der vertikalen Stellung verhindern und beim Einsetzen der Ofentür die Kraft aufnehmen, die durch das Anfahren der Anschläge 26, 27 im Tragrahmen (vgl. Fig. 3) durch die Bedienungsmaschine entstehen. Beim Verfahren des Tragrahmens laufen die Führungsrollen 22 zunächst auf dem senkrechten Teil 30 des Führungsgestelles entlang, dann auf einem Kurvenstück, das im unteren Bereich in eine 45° Schräge 32 übergeht und stehen am Ende der Fahrt in der Horizontalen über der Stütze 31.In the upper area of the guide frame 30 counter pressure rails 35 are provided, which prevent the support frame from tipping over in the vertical position and absorb the force when the furnace door is inserted, which is caused by the approach of the stops 26, 27 in the support frame (cf. Operating machine arise. When moving the support frame, the guide rollers 22 first run along the vertical part 30 of the guide frame, then on a curve piece which merges into a 45 ° bevel 32 in the lower region and, at the end of the journey, stand horizontally above the support 31.

Aus den Figuren 2 und 3 ist insbesondere die Konstruktion des Tragrahmens 21 ersichtlich. Er besteht im wesentlichen aus einer Konstruktion mit Hohlprofilen und ist unten und oben in den Traversen 23 und 24 mittels Zapfen längsaxial drehbar gelagert. Auf dem unteren Zapfen ist ein Getriebemotor 20 als Drehantrieb mit Bremsmotor aufgesteckt, der über eine Drehmomentenstütze an der Traverse 24 angelenkt ist. Die untere Traverse 24 ist an den Enden mit 2 Schwenkzapfen ausgerüstet, die in die Lager am Ende 18 des Auslegers eingeführt sind, so daß beim Verfahren der Antriebsvorrichtung eine Schwenkbewegung des Tragrahmens 21 erfolgen kann.The construction of the supporting frame 21 can be seen in particular from FIGS. 2 and 3. It consists essentially of a construction with hollow profiles and is rotatably supported axially below and above in the cross members 23 and 24 by means of pins. A geared motor 20 is attached to the lower pin as a rotary drive with a brake motor, which is articulated on the crossbar 24 via a torque support. The lower crossbeam 24 is equipped at the ends with 2 pivot pins which are inserted into the bearings at the end 18 of the boom, so that the support frame 21 can pivot when the drive device is moved.

Der Tragrahmen selbst ist ausgerüstet mit 4 verstellbaren Riegelhaken 25, in die die Riegelbalken der Ofentür eingeschwenkt werden, mehreren Winkelstücken 26, 27 auf denen die Dichtschneide der Ofentür aufliegt und die für Reparaturzwecke an der Dichtschneide abgenömmen werden können, einem in der Höhe verstellbaren und abnehmbaren Auflagerbock 28, für das Aufsetzen der Ofentür in der vertikalen Stellung und mit 4 Druckstützen 29 zum Einspannen des Ofentürrahmens, um beim Drehen in der horizontalen Lage ein Verrutschen der Tür im Tragrahmen zu verhindern.The support frame itself is equipped with 4 adjustable locking hooks 25, into which the locking bars of the furnace door are pivoted, several angle pieces 26, 27 on which the sealing edge of the furnace door rests and which can be removed for repair purposes on the sealing edge, one that is adjustable in height and removable Support bracket 28, for placing the oven door in the vertical position and with 4 pressure supports 29 for clamping the oven door frame to prevent the door from slipping in the support frame when rotating in the horizontal position.

Ein Fangbügel 36 im oberen Teil des Führungsgestells 30 soll ein Durchfallen der Ofentür beim Einsetzen verhindern, falls nach der Reparatur die Anbringung der Anschläge 26, 27 im Tragrahmen vergessen werden sollte.A safety catch 36 in the upper part of the guide frame 30 is intended to prevent the oven door from falling through when it is inserted if the attachment of the stops 26, 27 in the supporting frame should be forgotten after the repair.
