Abstract
Description
Schubroste, die als Kühl- oder Feuerungsroste verwendet werden, setzen sich alternierend aus feststehenden und in Förderrichtung hin- und herbeweglichen Querreihen von Rostplatten zusammen. Die Reihen von beweglichen Rostplatten werden sämtlich oder gruppenweise von einem beweglich gelagerten Rahmen getragen. Zur Lagerung werden Laufrollen verwendet, die auf einer Schiene abrollen. Sie unterliegen einem hohen Verschleiß, der zu einem unerwünschten Absenken der beweglichen Rostplattenreihen gegenüber den feststehenden führt. Man hat vorgeschlagen (DE-C-38 44 493), dies durch Lagervorrichtungen zu vermeiden, die eine Blattfeder umfassen, an der der bewegliche Teil des Rosts pendelnd aufgehängt ist. Sie haben den Nachteil, daß die Blattfeder sehr lang ausgeführt sein muß, damit die vertikale Komponente der Pendelbewegung vernachlässigbar gering bleibt. Die große Länge der Blattfedern ist nicht nur wegen ihres Platzbedarfs störend, sondern auch wegen ihrer starken Wärmedehnung, die zum Absenken des Rostteils und damit zu einer Beeinflussung der Lage der feststehenden und der beweglichen Rostplattenreihen im Verhältnis zueinander führt. Sliding grates used as cooling or firing grids, alternate between fixed and in the conveying direction reciprocating rows of grate plates together. The rows of movable grate plates are all or in groups of one movably mounted Worn frame. Rollers are used for storage, that roll on a rail. You are subject to a high Wear, which leads to an undesirable lowering of the moving Rows of grate plates opposite the fixed leads. Man has proposed (DE-C-38 44 493), this through storage devices to avoid that include a leaf spring on which the movable part of the grate is suspended. They have the disadvantage that the leaf spring can be very long must, so that the vertical component of the pendulum movement is negligible remains low. The great length of the leaf springs is not only annoying because of its space requirement, but also because of their strong thermal expansion, which helps to lower the grate part and thus to influence the position of the fixed and the movable rows of grate plates in relation leads to each other.
Der Erfindung liegt die Aufgabe zugrunde, einen Rost der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen, bei dem die Lageänderung des beweglichen Rostteils durch Wärmedehnung der Blattfedern verringert ist.The invention has for its object a grate in the Generic preamble of claim 1 to create, at the change in position of the movable grate part due to thermal expansion the leaf springs is reduced.
Die erfindungsgemäße Lösung besteht in den Merkmalen des Anspruchs 1 und vorzugsweise denjenigen der Unteransprüche. Demgemäß sind mehrere Blattfedern nebeneinander angeordnet. Der bewegliche Rostteil ist am unteren Ende einer ersten Blattfeder befestigt, deren oberer Aufhängepunkt mit dem unteren Ende einer zweiten , benachbarten Blattfeder zur Übertragung der Kräfte verbunden ist. Daraus ergibt sich eine N- oder zickzackförmige Anordnung der Blattfedern und der Glieder, die die Kraft vom oberen Ende der ersten Blattfeder auf das untere Ende der zweiten Blattfeder übertragen. Im Vergleich mit der Länge der Blattfedern der eingangs erläuterten Aufhängeanordnungen wird diese Länge auf mehrere Blattfedern aufgeteilt. Gleiche horizontale Bewegungsstrecke wird mit entsprechend geringerer vertikaler Ausdehnung der Lagervorrichtung erzielt. Entsprechend verringert sich auch diejenige Länge, die wärmedehnend wirksam wird, so daß der Wärmedehnungsfehler in der Positionierung der beweglichen Rostplattenreihen im Verhältnis zu den feststehenden Rostplattenreihen entsprechend vermindert wird.The solution according to the invention consists in the features of the claim 1 and preferably that of the subclaims. Accordingly, a plurality of leaf springs are arranged side by side. The movable grate part is at the lower end of a first Leaf spring attached, the upper suspension point with the lower End of a second, adjacent leaf spring for transmission of forces is connected. This results in one N- or zigzag arrangement of the leaf springs and the Limbs that transmit the force from the top of the first leaf spring transferred to the lower end of the second leaf spring. In comparison with the length of the leaf springs of the above Hanging arrangements will lengthen this to several Split leaf springs. Same horizontal movement distance becomes with a correspondingly smaller vertical expansion Storage device achieved. Accordingly, it also decreases the length that expands heat, so that the Thermal expansion errors in the positioning of the movable Grate plate rows in relation to the fixed grate plate rows is reduced accordingly.
Zickzack- oder N-förmig miteinander verbundene Blattfedern sind an sich bekannt (FR-A-497546; DE-B-1286816), jedoch ohne Bezug zu der der Erfindung zugrundeliegenden Aufgabe.Leaf springs connected in a zigzag or N-shape are known per se (FR-A-497546; DE-B-1286816), but without Relation to the object on which the invention is based.
Das Glied, das in der erfindungsgemäßen Lagervorrichtung die Verbindung zwischen dem oberen Ende der ersten Blattfeder mit dem unteren Ende der zweiten Blattfeder bewirkt, ist zweckmäßigerweise starr ausgebildet.The link that in the bearing device according to the invention Connection between the upper end of the first leaf spring with causes the lower end of the second leaf spring is appropriate rigidly trained.
Zweckmäßigerweise werden mehr als zwei Blattfedern in der angegebenen Weise miteinander verbunden, so daß der insgesamt erforderliche Bewegungsweg sich auf mehr als zwei Blattfedern verteilt. Dadurch kann die Höhe der Vorrichtung weiter verringert werden.Advantageously, more than two leaf springs are specified in the Way connected so that the total required movement path on more than two leaf springs distributed. This can further reduce the height of the device become.
Besonders vorteilhaft ist eine Anordnung, bei der diejenige Blattfeder, an deren unterem Ende der bewegliche Rostteil zu befestigen ist, zwischen einem Paar von sie haltenden Blattfedern angeordnet ist. Auf jeder Seite der Blattfeder, an der der Rostteil aufgehängt ist, befindet sich somit eine Blattfeder, von deren unteren Enden die Kräfte auf das obere Aufhängeende der erstgenannten Blattfeder übertragen werden.An arrangement in which the one is particularly advantageous Leaf spring, at the lower end of which the movable grate part closes attach between a pair of leaf springs holding them is arranged. On each side of the leaf spring, on the the grate part is suspended, there is a leaf spring, from the lower ends of the forces on the upper end of the suspension the former leaf spring are transferred.
Beiderseits der den Rostteil unmittelbar tragenden Blattfeder kann eine größere Zahl weiterer Blattfedern vorgesehen werden, so daß die Bewegungsstrecke auf mehrere Paare von Blattfedern aufgeteilt wird.On both sides of the leaf spring directly supporting the grate part a larger number of further leaf springs can be provided, so that the movement distance on several pairs of leaf springs is divided.
Nach einem besonderen Merkmal der Erfindung sind diejenigen Glieder, die die Kraft von dem Paar benachbarter Blattfedern zum oberen Aufhängepunkt der den beweglichen Rostteil tragenden Feder übertragen, starr miteinander verbunden. Das gilt auch für das nächstfolgende dieser Paare, falls vorhanden. Zweckmäßigerweise ist die Anordnung symmetrisch.According to a special feature of the invention are those Limbs representing the force of the pair of adjacent leaf springs to the upper suspension point of the one supporting the movable grate part Transfer spring, rigidly connected. That applies also for the next one of these pairs, if available. The arrangement is expediently symmetrical.
Das Glied, das jeweils die Kraft vom oberen Aufhängepunkt einer Blattfeder zum unteren Ende einer anderen Blattfeder überträgt, kann schräg zur (vertikalen) Richtung der Blattfedern verlaufen. Jedoch ist es auch möglich, die Blattfedern und die sie verbindenden Glieder parallel anzuordnen.The link, which is the force from the upper suspension point one leaf spring to the lower end of another leaf spring transmits, can be oblique to the (vertical) direction of the leaf springs run. However, it is also possible to use the leaf springs and to arrange the links connecting them in parallel.
Unter dem Begriff Blattfeder sollen auch Blattfederpakete verstanden werden, also Anordnungen von Federn, die gemeinsam derselben Beanspruchung unterworfen sind und sich gemeinsam parallel verformen.Leaf spring assemblies are also meant under the term leaf spring are understood, i.e. arrangements of springs that are common subjected to the same stress and together deform in parallel.
Die Lagervorrichtung wird zweckmäßigerweise in einem besonderen Gehäuse angeordnet zum Schutz vor mechanischen und thermischen Einflüssen. So kann die Vorrichtung auch innerhalb des Kühler- bzw. Feuerungsgehäuses angeordnet werden.The storage device is advantageously in a special Housing arranged to protect against mechanical and thermal Influences. So the device can also within of the cooler or firing housing can be arranged.

Hälfte des gesamten Auslenkungsbetrags leistet. Die Anordnung
ist N-förmig, wobei die Blattfedern 7a, 7b die vertikalen
Glieder bilden, deren entgegengesetzte Enden durch ein Verbindungsglied
13 verbunden sind. Dieses kann - wie in Fig. 2
gezeigt - schräg verlaufen. Es kann aber auch parallel zu den
Blattfedern 7a, 7b angeordnet sein.The simplest version of a storage device is shown in FIG.
