Definitions
- the present invention relates to a grate bar with a holder on one end part for rod holding members of the grate and a support part on its other end part for preferably inclined support on the one end part of another rod.
- grate bars 1 are known which have a holder in the form of a recess at one end section 3 and an upstanding support section 7 at their other end section 5. Such grate bars 1 are attached to the end section 3 with their holder placed on grate bars 9 so that they lie against each other inclined by the support section 7 of the one bar resting on the end section with the holder 3 of the front bar 1.
- grate bars of this type are exposed to extreme thermal stress, this being true in particular for the exposed support parts 7, while the other end part 3 of the bars 1 is covered by the respectively preceding grate bar.
- grate bars 1 often have to be replaced because the mentioned end section 7 is worn out, but it is additionally stressed by stoking, which is usually done by relative longitudinal displacement of every second grate bar with respect to the rest, as indicated by S in Fig. 1.
- the present invention aims to provide a grate bar of the type mentioned, with a long service life.
- both end parts have a holder and a support part.
- FIG. 2 shows a side view of a grate bar according to the invention.
- the rod 13 At both ends of the rod 13 it has support portions 15 which are formed by bending the rod ends in a rod cutting plane comprising a longitudinal axis A of the rod.
- the grate rod 13 can only be rotated when the one support part 15 is shown schematically as at 21 and can be applied to the rod 19 with the corresponding second recess 17.
- the wear 21 of the rod end used for support with the support section 15 subsequently does not in any way affect the use of the same rod section, with its recess 17 for mounting on the rod 19.
- the rod 13 is preferably made in one piece by welding.

Abstract
Description
- Die vorliegende Erfindung betrifft einen Roststab mit einer Halterung an seiner einen Endpartie für Stabhalteorgane des Rostes sowie einer Auflagepartie an seiner anderen Endpartie zur vorzugsweise geneigten Auflage auf der einen Endpartie eines weiteren Stabes.
- Es sind, wie in Fig. 1 schematisch dargestellt, Roststäbe 1 bekannt, die an ihrer einen Endpartie 3 eine Halterung in Form einer Einnehmung aufweisen und an ihrer anderen Endpartie 5 eine aufragende Auflagepartie 7. Derartige Roststäbe 1 werden mit ihrer Halterung an der Endpartie 3 auf Roststangen 9 aufgelegt, so dass sie gegenseitig geneigt aneinander aufliegen, indem die Auflagepartie 7 des einen Stabes auf der Endpartie mit der Halterung 3 des vorderen Stabes 1 aufliegt. Derartige Roststäbe sind je nach ihrem Einsatz einer extremen thermischen Beanspruchung ausgesetzt, wobei dies insbesondere für die freiliegenden Auflagepartien 7 zutrifft, während die andere Endpartie 3 der Stäbe 1 durch den jeweils vorangehenden Roststab abgedeckt ist. Deshalb müssen solche Roststäbe 1 des öftern ausgewechselt werden, weil die erwähnte Endpartie 7 abgenutzt ist, wird sie doch zusätzlich durch Schüren beansprucht, was üblicherweise durch Relativ-Längsverschiebung jedes zweiten Roststabes bezüglich der übrigen erfolgt, wie mit S in Fig. 1 angedeutet.
- Die vorliegende Erfindung bezweckt einen Roststab eingangs genannter Art zu schaffen, mit grosser Einsatzdauer.
- Dies wird dadurch erreicht, dass beide Endpartien eine Halterung und eine Auflagepartie aufweisen.
- Die Erfindung wird anschliessend anhand von Fig. 2 beispielsweise dargestellt, die eine Seitenansicht auf einen erfindungsgemässen Roststab zeigt. An beiden Enden des Stabes 13 weist er Auflagepartien 15 auf, die durch Umbiegen der Stabenden in einer, eine Stablängsachse A umfassenden Stab-Schnittebene gebildet sind. Auf der Innenseite der aufgebogenen Auflagepartien 15 ist je eine Halterungs-Einformung 17 vorgesehen, welche, wie links in der Fig. dargestellt, den Roststab 13 auf einer Roststange 19 haltert. Dank der symmetrischen Auslegung des Stabes 13, was Halterungseinnehmungen 17 und Auflagepartien 15 anbelangt, kann der Roststab 13 bei wie bei 21 schematisch dargestellter Abnutzung der einen Auflagepartie 15, lediglich gedreht werden und mit der entsprechenden zweiten Einnehmung 17 auf die Stange 19 aufgebracht werden. Wie ersichtlich, beeinträchtigt die Abnutzung 21 des zur Auflage mit der Auflagepartie 15 eingesetzten Stabendes nachmals den Einsatz derselben Stabpartie, mit ihrer Einnehmung 17 zur Halterung an der Stange 19, in keiner Weise. Der Stab 13 wird vorzugsweise onne Schweissarbeiten aus einem Stück gefertigt.
