Abstract
Description
Die Erfindung betrifft eine Beschickungsvorrichtung zum Transport von Chargierrosten in Wärmebehandlungsöfen, bestehend aus einem oder mehreren, die Chargierroste tragenden, in Führungsschienen laufenden, von Kettenrädern angetriebenen Kettensträngen, die sich aus einzelnen, mit Laufrollen versehenen Kettengliedern zusammensetzen.The invention relates to a loading device for transporting charging grates in heat treatment furnaces, consisting of one or more chain strands carrying the charging grids, running in guide rails and driven by chain wheels, which are composed of individual chain links provided with rollers.
Wärmebehandlungsöfen bestehen z.B. aus einer Hochtemperaturzone und einem Beschikkungstisch. Dazu können noch Abkühlund Abschreckzonen kommen, die jeweils durch Türen voneinander getrennnt sind.Heat treatment furnaces exist e.g. from a high temperature zone and a loading table. There may also be cooling and quenching zones, each separated by doors.
Es sind Beschickungseinrichtungen zum Chargieren solcher Wärmebehandlungsöfen bekannt, bei denen die Chargierroste mit in Führungsschienen laufenden, von Kettenrädern angetriebenen Kettensträngen durch die Behandlungszonen der Öfen gefahren werden. Der Transporterfolgt dabei mit Hilfe von Nocken und Klinken auf den Kettensträngen, die in die Chargierroste eingreifen.Charging devices for charging such heat treatment furnaces are known in which the charging grates are moved through the treatment zones of the furnaces with chain strands running in guide rails and driven by chain wheels. The transporter follows with the help of cams and pawls on the chain strands, which engage in the charging grates.
Eine gattungsgemäße Beschickungsvorrichtung für Wärmebehandlungsöfen ist aus der DE-AS 1279706 bekannt, bei der sich die Kettenstränge aus einzelnen, mit Laufrädern versehenen Kettengliedern zusammensetzen und der Transport der Chargierroste mit Hilfe von Nocken erfolgt. Diese Vorrichtung hat jedoch den Nachteil, daß die Chargierroste nicht direkt in den Ofen gefahren werden können, sondern vorher abgesetzt und dann über Stahlschienen und/oder Ofensteine geschleift werden müssen, was die Rostlebensdauer beträchtlich einschränken kann.A generic loading device for heat treatment furnaces is known from DE-AS 1279706, in which the chain strands are composed of individual chain links provided with impellers and the charging grids are transported with the aid of cams. However, this device has the disadvantage that the charging grates cannot be moved directly into the furnace, but must first be set down and then ground over steel rails and / or furnace stones, which can considerably limit the service life of the grate.
Es war daher Aufgabe der vorliegenden Erfindung, eine Beschickungsvorrichtung zum Transport von Chargierrosten in Wärmebehandlungsöfen zu finden, bestehend aus einem oder mehreren, die Chargierroste tragenden, in Führungsschienen laufenden, von Kettenrädern angetriebenen Kettensträngen, die sich aus einzelnen, mit Laufrollen versehenen Kettengliedern zusammensetzen, die die Chargierroste direkt an ihrem Bestimmungsort absetzen und wieder aus dem Ofen entfernen kann.It was therefore an object of the present invention to find a charging device for transporting charging grates in heat treatment furnaces, consisting of one or more chain strings carrying the charging grids, running in guide rails and driven by chain wheels and consisting of individual chain links provided with rollers place the charging grates directly at their destination and remove them from the oven.
Diese Aufgabe wurde erfindungsgemäß dadurch gelöst, daß die Führungsschienen sich in den Wärmebehandlungsofen hinein erstrecken, daß auf dem dem Wärmebehandlungsofen zuge-, wandten Ende der Kettenstränge auf einer Länge, die etwader Länge der Chargierroste entspricht, an den Achsen der Kettenglieder jeweils zwei nach oben weisende Kipphebel schwenkbar befestigt sind, an deren Ende Tragbalkensegmente angebracht sind, und daß am dem Wärmebehandlungsofen abgewandten Ende der die Tragbalkensegmente tragenden Kettenglieder an den Kettensträngen unmittelbar hinter den letzten Kipphebeln jeweils ein Stützanschlag und auf dem letzten Tragbalkensegment jeweils eine Hall tenocke befestigt sind.This object has been achieved according to the invention in that the guide rails extend into the heat treatment furnace, that on the end of the chain strands facing the heat treatment furnace over a length that corresponds approximately to the length of the charging grates, two upward points on the axes of the chain links Rocker arms are pivotally attached, at the end of which supporting beam segments are attached, and that at the end of the chain links carrying the supporting beam segments facing away from the heat treatment furnace, a support stop and a Hall tenocke are each fastened to the chain strands immediately behind the last rocker arms and in each case on the last supporting beam segment.
Vorzugsweise wird ein Tragbalkensegment von jeweils zwei oder drei Kettengliedern getragen. Außerdem kann es von Vorteil sein, wenn das erste und letzte Tragbalkensegment am äußeren Ende mit einer Rolle versehen sind.A supporting beam segment is preferably carried by two or three chain links each. It can also be advantageous if the first and last support beam segments are provided with a roller at the outer end.
Die Kettenstränge können stationär am Wärmebehandlungsofen angebracht sein. Vorteilhafterweise werden sie jedoch auf einem Chargierwagen angebracht, der außerdem einen oder mehrere Umwerfer trägt, die in Umwerfnasen an einzelnen Kipphebeln eingreifen können und mit einem Bügel versehen sind, der federnd seitlich der Tragbalkensegmente das Niveau der Tragbalkensegmente nach oben überragt.The chain strands can be attached to the heat treatment furnace in a stationary manner. However, they are advantageously mounted on a charging trolley, which also carries one or more front derailleurs, which can engage in single-lever rocker arms and are provided with a bracket that projects resiliently above the level of the supporting beam segments at the side of the supporting beam segments.
Diese Beschickungsvorrichtung hat den Vorteil, daß die Chargierroste von der Unterlage abgehoben und am Bestimmungsort direkt abgesetzt werden, ohne daß sie über Stahlschienen oder Ofensteine geschleift werden und damit hohen Zug- und Biegespannungen ausgesetzt werden müssen, die die Lebensdauer dieser Chargierroste starkbeeinträchtigen, insbesondere bei hohen Behandlungstemperaturen.This loading device has the advantage that the charging grates are lifted from the base and put down directly at the destination without being dragged over steel rails or furnace stones and thus have to be exposed to high tensile and bending stresses which severely impair the service life of these charging grates, especially at high ones Treatment temperatures.
Die Abbildungen I bis 111 zeigenschematisch eine beispielhafte Ausführungsform der erfindungsgemäßen Beschickungsvorrichtung, wobei Abbildung 1 eine Draufsicht, Abbildung 11 einen Längsschnitt entlang eines Kettenstranges und Abbildung 111 einen Querschnitt durch einen Kettenstrang gemäß Linie A-A wiedergibt.Figures I to 111 schematically show an exemplary embodiment of the loading device according to the invention, Figure 1 showing a plan view, Figure 11 a longitudinal section along a chain strand and Figure 111 a cross section through a chain strand according to line A-A.
Die Beschickungsvorrichtung besteht aus zwei-Kettensträngen (1), die in Führungsschienen (14) geführt und mittels Kettenräder (8) angetrieben werden. Diese Führungsschienen (14) befinden sich sowohl auf dem Chargierwagen (15) als auch im Arbeitsbereich des Wärmebehandlungsofens (16) und werden durch einen Festanschlag (12) begrenzt. Die Kettenstränge (1) setzen sich aus den einzelnen Kettengliedern (2) zusammen, die beiderseits mit Laufrollen (9) versehen sind. An den Achsen (7) der Kettenglieder (2) sind schwenkbare Kipphebel (3) befestigt, welche Tragbalkensegmente (4) tragen. Die äußeren Tragbalkensegmente (4) sind jeweils mit einer Rolle (5) versehen, die beim Heben und Senken der Tragbalkensegmente (4) an feststehenden Flächen abrollen können. Die Tragbalkensegmente (4) sind so bemessen, daß sie im aufgerichteten als auch im abgesenkten Zustand einen durchgehenden Tragbalken bilden.The loading device consists of two chain strands (1) which are guided in guide rails (14) and driven by chain wheels (8). These guide rails (14) are located both on the charging trolley (15) and in the working area of the heat treatment furnace (16) and are limited by a fixed stop (12). The chain strands (1) are composed of the individual chain links (2), which are provided on both sides with rollers (9). Swiveling rocker arms (3) are attached to the axes (7) of the chain links (2), which support beam segments (4). The outer supporting beam segments (4) are each provided with a roller (5) that can roll on fixed surfaces when lifting and lowering the supporting beam segments (4). The support beam segments (4) are dimensioned so that they form a continuous support beam in the erected as well as in the lowered state.
Mit dem Kettenstrang (1) fest verbunden ist ein Stützanschlag (6), der auf dem dem Wärmebehandlungsofen abgewandten Ende des Kettenstrangs (1) unmittelbar hinter den letzten Kipphebeln (3) sitzt. Außerdem ist auf dem letzten Tragbalkensegment (4) eine Haltenocke (17) befestigt.A support stop (6) is fixedly connected to the chain strand (1) and sits on the end of the chain strand (1) facing away from the heat treatment furnace directly behind the last rocker arms (3). In addition, a holding cam (17) is attached to the last supporting beam segment (4).
Ein oder mehrere Kipphebel (3) sind mit Umwerfnasen (10) versehen, in die jeweils ein Umwerfer (11) eingreifen kann, der die durch den Stützanschlag (6) aufgerichteten Tragbalkensegmente (4) absenken kann, indem die Kipphebel (3) zur anderen Seite hin umgekippt werden. Diese Umwerfer (11) sind mit einem Bügel (13) versehen, der seitlich der Tragbalkensegmente (4) diese nach oben überragt. Das hat zur Folge, daß bei Beladung der Tragbalkensegmente (4) mit einem Chargierrost der Bügel (13) heruntergedrückt wird und der Umwerfer (11) nicht in Funktion treten kann.One or more rocker arms (3) are provided with overturning lugs (10), in each of which a front derailleur (11) can engage, which can lower the supporting beam segments (4) raised by the support stop (6) by moving the rocker arms (3) to the other Be tipped over. These derailleurs (11) are provided with a bracket (13) which projects laterally above the supporting beam segments (4). The result of this is that when the support beam segments (4) are loaded with a charging grate the bracket (13) is pressed down and the front derailleur (11) cannot function.
Anhand der Abbildungen wird im folgenden die Arbeitsweise der Beschickungsvorrichtung erläutert:
- Beim Einfahren eines Chargierrostes in den Wärmebehandlungsofen (16) steht dieser auf dem Chargierwagen (15). Über das Kettenrad (8) wird der Kettenstrang (1) unter den Chargierrost geführt, wobei die Tragbalkensegmente (4) auf den Kettengliedern (2) aufliegen. Sowie der Stützanschlag (6) das Kettenrad (8) passiert hat und dieser Kettenstrangteil dadurch von einer vertikalen Lage in eine horizontale überführt wird, drückt der Stützanschlag (6) gegen die Kipphebel (3) und bewirkt somit ein Anheben der Tragbalkensegmente (4) und damit auch des Chargierrostes. Dieser wird in den Wärmebehandlungsofen (16) eingefahren und dort abgesetzt. Das geschieht mittels der Haltenocke (17), die in eine entsprechende Vorrichtung an der Ofentür einrastet und beim Zurückfahren des Kettenstranges (1) die Tragbalkensegmente (4) abkippt, sodaß sie wieder auf den Kettengliedern (2) aufliegen.
- When a charging grate is moved into the heat treatment furnace (16), it stands on the charging trolley (15). The chain strand (1) is guided under the charging grate via the chain wheel (8), the supporting beam segments (4) resting on the chain links (2). As soon as the support stop (6) has passed the sprocket (8) and this part of the chain strand is thereby transferred from a vertical position to a horizontal position, the support stop (6) presses against the rocker arm (3) and thus causes the support beam segments (4) and thus also the charging grate. This is moved into the heat treatment furnace (16) and deposited there. This is done by means of the retaining cam (17), which engages in a corresponding device on the furnace door and tilts the supporting beam segments (4) when the chain strand (1) is moved back, so that they rest on the chain links (2) again.
Beim Herausfahren des Chargierrostes aus dem Wärmebehandlungsofen (16) werden die durch den Stützausschlag (6) aufgerichteten Tragbalkensegmente (4) beim Überfahren des Umwerfers (11) durch Eingriff in eine entsprechende Umwerfnase (10) umgekippt, liegen damit auf den Kettengliedern (2) auf und werden unter den Chargierrost gebracht. Beim Anfahren des vorderen Tragbalkensegments mit der Rolle (5) an den Festanschlag (12) werden die Tragbalkensegmente (4) und damit der Chargierrost angehoben und können so aus dem Wärmebehandlungsofen entfernt werden. Sowie der Stützanschlag (6) im Kettenrad (8) indie vertikale Lage gedreht wird, verlieren die Tragbalkensegmente (4) ihre Stütze, werden daher abgesenkt und setzen den Chargierrost auf dem Chargierwagen (15) ab.When the charging grate is moved out of the heat treatment furnace (16), the support beam segments (4) erected by the support deflection (6) are tipped over when the front derailleur (11) is passed over by engaging in a corresponding knock-over nose (10), so that they rest on the chain links (2) and are placed under the charging grate. When the front support beam segment with the roller (5) approaches the fixed stop (12), the support beam segments (4) and thus the charging grate are raised and can thus be removed from the heat treatment furnace. As soon as the support stop (6) in the chain wheel (8) is turned into the vertical position, the supporting beam segments (4) lose their support, are therefore lowered and place the charging grate on the charging trolley (15).
