Definitions

a sliding grate consists of overlapping roof tiles Cross rows of grate plates that are alternately fixed and arranged to move back and forth in the longitudinal direction are.
the movably arranged rows of grate plates are all or arranged in groups on frames by height guides are worn and their correct lateral alignment is determined by side guides.
Become conventional for The height guide uses rollers on rails that are used for the purpose the side guide with interacting flanges or Guide strips are provided (EP-A-378 821, Fig. 1). It is also known (loc. cit., Fig. 2), elongated for the height guidance To use traction elements on which the movable The grate part is suspended in an oscillating manner. In this context fell into disrepair one on the thought (loc.
the invention avoids these disadvantages by the features of claim 1 and preferably those of the subclaims.
organs for the lateral guidance which are analogous to those of the oscillating grate suspension; the principle of action is different. While at the oscillating height guide inevitably a circular arc Rust movement takes place, the side guide must be straight run. That is why the principle of pendulum guidance is suitable in principle not as a side guide. That also applies in particular if according to the invention horizontal pendulum guides are arranged antagonistically on both sides because the Arcs of the mutual pendulum guides do not match.
the invention is based on the knowledge that a strict guidance on the entire route is not necessary is and that it is sufficient if the grate in individual Points of its path of movement a certain lateral Position is imposed.
inextensible Traction elements is the guide to the reversal points or the adjacent area limited. In between is theoretical no guidance available.
the side-acting ones Forces that deflect the grate from its central position could not be so big that one would have to fear that it would to the next opportunity to correct the position from the side, that is, until the next turning point is reached, its tolerance range leaves.
the tension elements dimensioned so that the lateral movement of the moving Rust part up to the limit of its tolerance range Traction in one part of the movement distance zero or insufficient is and only when approaching one or the other Reversal point exceeds that for a lateral Corrective movement of the movable grate part is required.
the invention also includes such designs a, where through targeted measurement of elasticity and Length of the tension elements is achieved with lateral deflection of the moving grate part up to the tolerance limit on everyone Point of the movement distance is sufficient for side correction Traction difference is generated. However, this is as I said, not necessary because of a sudden lateral movement of the movable grate part that this leads beyond the tolerance range, not to be counted got to.
the tension elements in relation to The longitudinal movement distance of the moving grate part should be long so that your leadership arc becomes flat. In general it suffices if the tension elements each from one side edge of the moving grate part to a neighboring side edge Component run, so usually over the entire Width of the moving grate part.
connection points of the tension elements with the grate part and the stationary structure is not subject to wear, they are expediently designed as flexible joints.
a movable grate part which is formed by two pairs of tension elements 3 during its back and forth in the direction of arrow 4 Movement is performed.
a grate part has one Width of several meters and a length of ten to twenty Meters. Its range of motion is of the order of magnitude of 0.1 m. The permissible lateral deviation is in the range less millimeters.
the rust can, as far as not here described differently, carried out conventionally and required no explanation as far as it is known. It is enough Notice that the grate surface of alternating fixed and longitudinally movable transverse rows of grate plates is formed.
FIG Grate plates 5 which is supported by a cross member 6, the be carried by a frame 2 in a manner not shown can.
Fixed grate plates or fittings 7 provided with the end of the moving grate plate row include a gap 8.
the width of this gap should be as low as possible to avoid unnecessary air loss and To avoid rust diarrhea. It is a few millimeters. So that the moving grate parts do not touch the fixed side limits 7 grind, resulting in rapid destruction and would lead to the loss of energy, it requires the guidance mentioned of the moving grate part.
the tensile cords are 3, which guide the moving grate part of spring steel strips formed, one end of which on the wall 1 or another fixed structure anchored by means of a holder 9 while the other end is on the moving grate part is anchored by means of a bracket 10.
the ends of the spring steel strips 3 are useful in these brackets rigidly defined, their angular mobility not by relative movements inside the brackets, but by bending the spring steel strips is effected.
spring steel bands are because of their simplicity particularly advantageous. Instead, you can also in rigid parts are used, the ends with bending elements are provided, which in turn are anchored in the brackets are.
the rigid parts of the tension elements are, for example Bars, flat steel, tubes and the like.
the flexible elements can be made of spring steel sections or Wire rope sections can be formed, each on the one hand are connected to the rigid parts and on the other hand with the brackets.
Chains can also be used as tension elements, but what the The disadvantage is that the last one, due to joint movement stressed chain links are subject to wear. Finally, there is also the option of mounting the brackets in educate yourself, which is also the disadvantage of Has wear and tear and interchangeability and / or readjustability demands.
the tension elements 3 are advantageously approximately parallel to Transverse extension of the movable grate part arranged, so in essentially horizontal. Deviations from the horizontal Direction can be caused by constructive conditions his. Slight deviations from the horizontal direction disturb the function in general not. However, the angle ⁇ Do not exceed 20 °. It is preferably below 15 °, for example between 5 ° and 10 °.
Two antagonistic tension elements are expedient arranged as a couple close to each other because of a large one Longitudinal distance to undesirable bending stress of the movable Rust parts.
the tension elements are formed by leaf-shaped bending elements the bending plane should be or contain such elements (this is the level in which the bending movement takes place) of these elements parallel to the direction of movement of the are moving grate plate part, as indicated in Fig. 4 is.
Three fixed grate plates 15 can be seen therein, supported by construction parts, not shown are, and in each case moving grate plates 5, which over Cross member 6 are carried by frame parts 2.
the direction of movement the moving grate parts runs parallel to Extension plane of the moving grate plates 5, ie in the direction of the arrow 4.
the brackets (only indicated schematically) 9, 10 for the leaf-shaped spring steel strips 3 are therefore arranged at an angle so that the leaf plane is perpendicular to Arrow direction 4 runs.
the guide effect of the tension elements 3 is based on the diagram illustrated in Fig. 5. It is assumed that the moving grate part is guided so that a point under consideration ideally on the dash-dotted line 20 moved between the reversal points 21, 22. The side The tolerance range of this movement is indicated by lines 23, 24 narrowed down. There are tension elements not shown, whose end points describe exaggerated arcs, the freedom of movement within the moving grate part of the area delimited by the arcs 25, 26. These arcs lie in most of the movement path outside of lines 23, 24 and would theoretically be one Allow tolerance range to be exceeded. In practice however, this does not happen.
the Tension elements are elastic.
the arcs 25, 26 are then determined by the length of the tension elements at which they are so stretched that their tensile force is the lateral resistance equalizes that when correcting the position of the grate is overcome.
the moving grate part then acts even a certain force in the direction of correction if the point under consideration is the circular arc 25 or 26 in FIG. 5 has not yet reached. Even if this correction force is less may be as the force required for lateral displacement rust is necessary, since it is capable of those Compensate forces at least partially during the Stroke an undesirable side shift of the moving Cause part of the grate so that this undesirable lateral movement is lower.
