Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the movable frame 2 of a grate cooler, its grate plates and stationary parts omitted for the sake of clarity are carried by four bearing devices in housings 1.
  • cross members 5 are arranged on the frame, the ends of which are suspended from the bearing devices.
  • the bearing devices can be in the cooler or guide housing to get integrated. It is also possible to put them alongside (outside) to install the cooler or furnace housing. Of course, more than the four indicated Storage devices are used.
  • FIG. 2 The simplest version of a storage device is shown in FIG. 2.
  • the upper end of the second leaf spring 7b is on one attached support element, not shown. From the lower one End 3 of this leaf spring is the force absorbed by it transferred according to arrow 10 to point 6, at which the first Leaf spring 7a is suspended, the lower end 9 with the part of the grate to be carried is connected.
  • a horizontal one Deflection 4 of point 9 leads to a corresponding bending of leaf springs 7a, 7b, each of these springs Half of the total deflection amount.
  • the order is N-shaped, the leaf springs 7a, 7b the vertical Form links, their opposite ends by a connecting link 13 are connected. This can - as in Fig. 2 shown - run obliquely. But it can also run parallel to the Leaf springs 7a, 7b may be arranged.
  • FIG. 4 shows the element according to FIG. 2 in triple series connection. That is, there are four leaf springs 7a to 7d provided, each successive by links 13 are interconnected. The entire path of movement 4 is therefore divided into four leaf springs.
  • Fig. 3 shows a storage device in which the arrangement 2 symmetrically on both sides of the first leaf spring 7a is arranged.
  • This first leaf spring 7a the lower end 9 is connected to the movable grate part, is on her upper end 6 of two symmetrically arranged in mirror image second leaf springs 7b, the upper ends 8 of anchored a solid structure, not shown are and their traction via links 13 from their lower ends 3 is transferred to the upper end 6 of the leaf spring 7a.
  • the transmission members 13 can be characterized in that their upper Flanges that clamp the upper end of the leaf spring 7a are firmly screwed together, rigidly connected his. Instead, or in addition, their lower ones Ends 3 are connected to each other without freedom of movement of the lower end 9 of the leaf spring 7a.
  • the two connecting links 13 can also consist of one Be formed. The stability of the device will improved by the connection.
  • Fig. 5 shows a storage device, which - analogous to the embodiment 3 - on a symmetrical, bilateral Support of the first leaf spring 7a is based on the movable Grate part is connected at the lower end 9.
  • the path of movement 4 divides in comparison with the embodiment according to Fig. 3 on a larger number of second and third leaf springs on, so that a lower overall height in relation to Movement path can be selected.
  • the connecting links 13b can, for example, by a coupling rod, which is indicated by dash-dotted lines at 14, be rigidly connected to each other without the possibility of movement the other links of the bearing device in between to affect.
  • the bearing devices shown are with articulated gears comparable, in which the joints are replaced by spring elements are.
  • Fig. 6 illustrates the height offset in the lateral Deflection of a leaf spring suspension. If the lower, clamped End 9 of the broken line shown in the idle state Leaf spring in the manner shown with solid lines by the amount 12 compared to the upper, also clamped When the leaf spring is deflected, the lower one rises End by the amount of 11. Spread out the deflection several leaf springs connected in series according to the invention, the height offset is reduced accordingly.
