Definitions

  • the invention relates to a moving grate cooler according to the preamble of claim 1.
  • the invention is therefore based on the object of designing a moving grate cooler of the type required in the preamble of claim 1 in such a way that the device used to support the oscillating frame on the fixed abutment can be manufactured in a simple manner and is practically maintenance-free in operation - even at higher temperatures .
  • the device for supporting the oscillating frame is formed by supporting rockers, which are provided at their upper and lower ends with a convexly curved supporting surface and roll freely over these supporting surfaces on the oscillating frame and on the stationary abutment.
  • Such a support is completely maintenance-free, since a pure rolling process takes place on the contact surfaces, which does not require lubrication and whose function cannot be impaired by temperature influences.
  • a guide device is advantageously provided according to the invention, which at the same time prevents the support arms from tipping in the longitudinal direction of the cooler. With suitable dimensions, significant wear on this guide device is not to be expected.
  • the thrust grate cooler illustrated in a detail in FIGS. 1 to 4 contains an oscillating frame 1 which can be moved to and fro in the conveying direction (ie perpendicular to the plane of the drawing in FIG. 1) by means of a drive device (not shown), which is attached to a fixed abutment 2 by support arms 3 , 3 'is supported, which are connected to one another via two rods 4, 5.
  • the support arms 3, 3 ' are provided at their upper and lower ends with a convexly curved support surface 3a and 3b, respectively, via which they roll freely on a running shoe 6 or 7 connected to the vibration frame 1 or the fixed abutment 2.
  • the running shoes 6, 7 are provided with a flat running surface 6a or 7a.
  • a guide device is also provided. It contains two guide members 8, 8 ', which are firmly connected to the support arms 3, 3' via the rods 4, 5. At their upper and lower ends, the guide members 8, 8 'each have a guide slot 8a.
  • the guide device mentioned includes two guide pins 9, 10 and 9 ', 10' fastened to the oscillating frame 1 or to the fixed abutment 2, the center distance of which corresponds to the distance between the two support surfaces 3a, 3b of the support arms 3, 3 'and into which engage lower and upper guide slots 8a of the guide members 8, 8 '.
  • the center distance of the guide pins 9, 10 or 9 ', 10' is thus chosen so that practically no relative movement occurs in the guide slot 8a (0.1 mm). Significant wear on the guide device is therefore not to be expected.
  • FIG. 2 to 4 illustrate how, when the oscillating frame 1 moves back and forth (in the direction of the double arrow 11), the support arms 3, 3 'with their upper and lower support surfaces 3a, 3b on the oscillating frame 1 or on the stationary abutment 2 are free unroll.
  • the guide device guide members 8, 8 'and guide pins 9, 10 or 9', 10 '
  • the support rockers 3, 3 ' are provided in the same way as in the embodiment already explained at their upper and lower ends, each with a convex curved support surface, by means of which they are attached to the frame with the swing frame 1 or the stationary abutment 2 connected running shoe 6 or 7 roll.
  • the guide device is designed in the variant in FIGS. 5 and 6.
  • An upper and lower toothed segment 12, 13 and 12 ', 13' are rotatably connected to the two support rockers 3, 3 '. These toothed segments are in engagement with toothings 6b, 7b and 6b ', 7b' which are provided on the running shoes 6, 7 and 6 ', 7' and which form straight toothed racks (see FIG. 6).
  • the average tooth spacing of the toothings 6b, 7b and 6b ', 7b' corresponds to the distance between the two support surfaces 3a, 3b of the support rockers 3, 3 '.
  • the guide device ensures that the support surfaces 3a, 3b of the support rockers 3, 3 'perform a pure rolling movement and no sliding movement relative to the oscillating frame 1 or the stationary abutment 2.
