Abstract

Grid used for heating or cooling is supported by a an arrangement of several leaf springs (7) adjacent to one another, such that forces (10) from the bottom (3) of one leaf spring (7) are transmitted into the upper suspension point (6) of another leaf spring (7), at the lower end (9) of which the grid can be fastened or is fastened. Preferably more than two leaf springs are provided and the leaf spring (7a) at the lower end of which the grid is fastened is positioned between a pair of leaf springs (7b) holding it. The support arrangement is preferably located outside the cooling or heating housing.

Description

Die Erfindung betrifft eine Vorrichtung zur wartungsarmen und verschleißfreien Lagerung der beweglichen Teile 2 in Rostkühlern und Rostfeuerungen.The invention relates to a device for low-maintenance and wear-free storage of the moving parts 2 in grate coolers and grate furnaces.

Lagerungen üblicher Bauart weisen Laufrollen auf, die auf einer Schiene hin- und herrollen. Die Laufrollen sind über Wälz- oder Gleitlager mit den beweglichen Teilen des Schubrostes verbunden. Insbesondere ist bekannt, daß derartige Lagerungen einem hohen Verschleiß unterliegen, was zum Absenken der beweglichen Teile führt, und so hohe Folgekosten verur­ sacht. Ferner sind Lagerungen bekannt, bei denen der Rost an Blattfedern, ähnlich eines Pendels aufgehängt ist. Die beweglichen Teile des Rostes bewegen sich bei dieser Art der Lagerung auf einem Bogen. Da man eine möglichst geradlinige Bewegung erreichen will, müssen die Blattfedern lang ausgeführt werden, um einen großen Radius zu erhalten. Diese Art von Lagerung ist aufwendig. Ferner führen Temperaturänderungen zu Längenausdeh­ nung der Blattfedern und damit zum Absenken des Schubrahmens. Eine geradlinige Bewe­ gung ist mit einer derartigen Lagerung nicht möglich.Bearings of conventional design have castors that roll back and forth on a rail. The rollers are on roller or slide bearings with the moving parts of the sliding grate connected. In particular, it is known that such bearings are subject to high wear subject, which leads to the lowering of the moving parts, causing high follow-up costs gently. Bearings are also known in which the rust on leaf springs, similar to one Pendulum is suspended. The moving parts of the grate move with this type of Storage on an arch. Since you want to achieve as straight a movement as possible, the leaf springs must be made long to obtain a large radius. This Type of storage is expensive. Furthermore, temperature changes lead to linear expansion leaf springs and thus to lower the push frame. A straightforward movement supply is not possible with such storage.

Der in dem Schutzanspruch 1 bis 7 angegebenen Erfindung liegt das Problem zugrunde, eine wartungsarme und verschleißfreie Lagerung zu schaffen, mit welcher eine möglichst geradlinige Bewegung erreicht wird, die imstande ist, hohe Lasten aufzunehmen, und bei der die Längenausdehnung durch Temperaturänderung minimiert wird.The invention specified in the protection claims 1 to 7 is based on the problem of creating a low-maintenance and wear-free bearing with which a movement which is as straight as possible is achieved, which is capable of absorbing high loads, and in which the linear expansion is minimized by temperature change.

Dieses Aufgabe wird gemäß der Erfindung durch eine Einrichtung mit den Merkmalen des Schutzanspruches 1 bis 6 gelöst.This object is achieved according to the invention by a device with the features of claims 1 to 6 .

Eine weitere vorteilhafte Ausgestaltung der Erfindungen ist im Schutzanspruch 7 angegeben. Ein Ausführungsbeispiel wird anhand der Fig. 1 erläutert. Fig. 1 zeigt bewegliche Teile 2 von Rostkühlern bzw. Rostfeuerungen. Diese beweglichen Teile 2 sollen eine möglichst geradli­ nige Bewegung 4 ausführen. Die beweglichen 2 Teile sind mit Querträgern 5 verbunden. Die Querträger sind mit den Federsystemen 1 verbunden, die sich auf jeder Seite an den Enden der Querträger befinden. Die Federsysteme 1 können im Kühler- bzw. Ofengehäuse integriert werden. Es ist auch möglich, die Federsysteme 1 neben dem Kühler- bzw. Ofen­ gehäuse zu installierten. Die beweglichen Teile 2 des Rostes können mit vier oder mehr Federsystemen 1 gelagert werden.A further advantageous embodiment of the inventions is specified in the protection claim 7 . An embodiment is explained with reference to FIG. 1. Fig. 1 shows movable parts 2 of grate coolers or grate furnaces. These moving parts 2 should perform a straight-line movement 4 as possible. The movable 2 parts are connected to cross members 5 . The cross members are connected to the spring systems 1 , which are located on each side at the ends of the cross members. The spring systems 1 can be integrated in the cooler or furnace housing. It is also possible to install the spring systems 1 next to the cooler or furnace housing. The movable parts 2 of the grate can be stored with four or more spring systems 1 .

Fig. 2 zeigt wie eine Kraft 4 vom Ende einer Blattfeder in den Aufhängepunkt 6 einer ande­ ren Blattfeder geleitet wird. Fig. 2 shows how a force 4 is passed from the end of a leaf spring into the suspension point 6 of another leaf spring.

Fig. 3 zeigt, ein Federsystem bei dem die Blattfedern nacheinander angeordnet sind. Die beweglichen Teile 2 werden am Aufhängepunkt 9 befestigt. Fig. 3 shows a spring system in which the leaf springs are arranged one after the other. The moving parts 2 are attached to the suspension point 9 .

Fig. 4 zeigt ein Federsystem bei dem die Blattfedern ineinander verschachtelt sind. Die be­ weglichen Teile 2 werden am Aufhängepunkt 9 befestigt. Fig. 4 shows a spring system in which the leaf springs are nested. The movable parts 2 are attached to the suspension point 9 .

Fig. 5 zeigt ein Federsystem bei dem die Blattfedern nebeneinander angeordnet sind. Die beweglichen Teile 2 werden am Aufhängepunkt 9 befestigt. Fig. 5 shows a spring system in which the leaf springs are arranged side by side. The moving parts 2 are attached to the suspension point 9 .

Fig. 6 zeigt den Höhenversatz 11 bei herkömmlichen Lagerung der beweglichen Teile an Blattfedern. Fig. 6 shows the height offset 11 in conventional storage of the moving parts on leaf springs.
