Definitions

  • the invention relates to a grate covering for mechanically moving step-shaped grate of large firing, in which there are several relatively movable roat bars in the individual steps, which are clamped in the transverse direction by projecting stops which are passed through openings in the outer ribs of the adjacent bars and on fit the inside of the outer rib.
  • a laterally protruding hook is provided on an outer rib of a grate bar, which after insertion through a special insertion opening during the relative stroke is guided in a longitudinal slot of the outer rib of the adjacent grate bar and thereby with it Hook part slides along the inner wall of the outer rib.
  • the clamping takes place from one rod to the respective neighboring rod, the frictional force and thus the force for executing a relative stroke is doubled when jamming occurs on both flanks of a rod.
  • Jamming between grate bars can be caused by stones and slag as well as by penetrated iron parts, as can be the case with a refuse furnace.
  • the object of the invention is to design a grate covering of the type described in such a way that the distance between the individual grate bars or the gaps between the grate bars can be kept smaller and the frictional forces during the relative displacement and the associated wear are reduced.
  • the stops are due to the inventive design on the inside of the outer ribs of such grate bars, which are fixed during the relative stroke, no displacement occurs between the stops and these outer ribs and thus no wear on the ribs and the stops.
  • the grate bar movable during the relative stroke is now moved between two grate bars which are stationary during the relative stroke and which have a constant distance due to the clamp.
  • the movable grate bar is thus displaced relative to the unit consisting of the two adjacent bars and the fixed bracket, the bracket gripping through the movable grate bar with play.
  • the gap widths can be reduced to less than 1 mm. This avoids that larger parts can penetrate between relatively movable grate bars. If there is nevertheless jamming due to many small parts, the resultant force leads to the movable grate bar being in contact with a stationary one Grate bar is pressed and under the action of this force during the relative displacement with its flank along the flank of the fixed grate bar.
  • Another significant advantage is that the resistance to displacement of the movable grate bar due to jamming remains constant, regardless of whether the jam occurs in one or both gaps between the movable grate bar and the two fixed grate bars held together by a clamp.
  • the displacement resistance is doubled when jamming occurs in both columns on both sides of the movable grate bar, since the clasps on both sides of the movable grate bar are independent of one another, so that the forces building up on the hooks add up.
  • the gap width depends on the adjacent grate bars on the manufacturing accuracy in the manufacture of the grate bars and the clamp, which cannot be increased arbitrarily for economic reasons.
  • the effective length of the clamp can be adjusted in accordance with a further development of the invention adjustable.
  • a first possibility of making the clamp adjustable and readjustable is that an adjusting screw is provided on at least one of the stops, which can be made in one piece with the clamp bolt, which engages on the inside of the outer rib.
  • the stops are designed as transverse to the clamp bolt by means of adjusting screws arranged at the ends thereof, which at one end have conical projections which, in the operating position, also have on the inside the inclined surfaces arranged on the outer ribs interact.
  • the clip thus consists of a simple, straight clip bolt, which has threaded bores at the ends essentially transversely to its longitudinal axis, into which the set screws are screwed. Since both the set screws and the inside of the outer ribs have inclined surfaces that are in contact with each other, the desired distances can be adjusted and adjusted.
  • stops are formed by nuts that can be screwed onto the ends of the clamp bolt.
  • insertion openings for the stops are provided at least in the outer ribs of the fixed grate bars. If these stops are firmly connected to the clamp bolts, the movable grate bars also have corresponding openings. So that the connection cannot come loose during operation, the clips are locked after insertion. This can be done according to the invention in that the clamp is rotated in the operating position relative to the insertion position.
  • clamp bolt is made of a round material, there is a possibility that it will turn back during operation.
  • the clamp bolt can have sliding blocks on which the movable grate bar is slidably guided. It is advantageous if the sliding blocks have a shape that deviates from the circular shape, so that they in turn cannot be subject to any rotational movement.
  • the arrangement of sliding blocks on the clamp bolt also has the advantage that wear-resistant materials can be used because, despite the play in the longitudinal slot, it cannot be ruled out that during the stoking movements a relative movement occurs perpendicular to the grate bars between adjacent grate bars, so that the movable ones Grind the grate bars along the clamp bars.
  • the sliding blocks reduce wear without it being necessary to manufacture the entire bracket from a particularly wear-resistant material.
  • Another way to lock the clip in its operating position is that at the. Underside of the locking bolt locking bolts are provided, which after inserting the stops in the Insertion openings can be insertable into these and can hold the clip in a position that is displaced relative to the insertion position and thus locked.
  • the locking bolts can be secured in their locking position against unintentional shifting.
  • the locking of the bracket can be carried out in a simple manner in that the insertion openings for the adjusting screws serving as stops in the outer rib are assigned to that side of the locking bar which is opposite the conical projections .
  • the set screws are inserted for insertion into a position in which the conical projections are located essentially within the clamp bolt and are then rotated after being pushed through the outer rib into an operating position in which the conical projections protrude above the clamp bolt.
  • the insertion openings are provided on the side opposite the conical projections, the clamp can no longer be released from the fixed grate bars.
  • two fixed grate bars and one movable grate bar of one step are combined to form a unit, it being entirely possible for five or seven or a higher odd number of grate bars to be combined to form one unit. Then only the distance between the two outer grate bars of a unit is defined. The distances between the individual grate bars of this unit can vary within the unit. The grating bars of a unit are thus held at a certain maximum distance from one another by the clamping.
  • a gap formation can occur not only between the grate bars, but also between the edge bar of a step and the boundary plates.
  • the edge bars of the one grate covering side of the fixed grate steps can be held on the side boundary plates of the firing grate by clamps at a fixed, adjustable and adjustable distance. This prevents the formation of edge gaps between the edge bars and the boundary plates, which can no longer be compensated for by other compensation devices. This is the case when parts are inserted between the edge bar, which is immovable with respect to the boundary plates, and the latter. Such parts can dei. Widen marginal gap, which allows larger and larger parts to penetrate. There is no self-cleaning effect due to the lack of relative movement between the edge bar and the boundary plates in the fixed steps.
  • the invention solves the problem of edge gap formation in fixed steps.
  • the clamps can be held on the boundary plates so as to be displaceable perpendicular to the grate bar surface. Details and advantageous developments of the brackets for the edge bars result from the subclaims.
  • grate levels consisting of grate bars 1 fixed during the relative stroke and grate bars 2 movable for this purpose during the relative stroke are provided, which either lie on movable support frames 3 in the case of movable steps or on fixed support frames 4 in the case of fixed steps .
  • the respective fixed grate bars 1 are essentially without play at their hanging end 5 on a hanging rail 6 or 7 of the support frame 3 or 4, while the grate bars 2 movable relative to these grate bars rest with a longitudinal play on the support frame of the movable or fixed step.
  • two grate bars 1 which are fixed with respect to their supporting frame, are held at a first distance from one another by means of a clamp, and the grate bar 2, which is displaceable relative to these fixed grate bars, not only moves relative to its neighboring ones Rust bars 1 and the hanging rail 6 or 7, but also opposite the clamp, which prevents its neighboring bars from being removed from one another.
  • the bracket which holds the fixed grate bars 1 together is designated by 8 and comprises a bracket bolt 9 as well as hook-like projections 10 formed at its ends, which are integrally formed with the bracket bolt and on both sides protrude transversely to the bolt 9.
  • the inner ribs 11 and the outer ribs 12 of the movable grate bar 2 and the outer ribs 13 of the fixed grate bars 1 have insertion openings 14 and 15, respectively.
  • the insertion openings 15 in the outer rib 13 of the fixed grate bar 1 are adapted to the shape of the hook-like extension 10 and run perpendicular to the back surface of the grate bar 1.
  • the clamp 8 can hold the fixed grate bars 1 at a certain distance from one another, or so that during operation the stops 10 can no longer slide out through the insertion openings 15 of the fixed grate bar 1, the clamp 8 is rotated by means of a key 16 which is attached to one Lever 17 attacks, which is firmly connected to the clamp bolt 9.
  • the key 16 has at its front end a pocket 18 with two stops 19 in which the lever 17 is received, the stops 19 mutually engaging the lever 17 while the clamp 8 is being rotated.
  • the movable grate bar 2 has a longitudinal slot 20 which is connected to the insertion opening 14 and is dimensioned such that the movable grate bar 2 can move with play 21 relative to the clamp bolt 9 of the clamp 8 in accordance with its relative displacement with respect to the fixed grate bars 1.
  • an adjustable clamp 25 which has a clamp bolt 26 and two hook-like stops 27.
  • One of the stops 27 is provided with a threaded bore 28 into which a set screw 29 can be screwed, which bears against the inside of the outer rib 13 of one of the two grate bars 1 connected by the clamp 25 and thus the mutual distance between the two fixed grate bars 1 and thus allows the gap widths 22 to be adjusted.
  • an insertion opening 30 is provided in each outer rib 13 of a fixed grate bar 1, the width of which is essentially adapted to the width of the clamp bolt 26, which is rectangular in cross section, and the height of which corresponds to the height of the stop 27, increased by a certain movement game, corresponds.
  • a longitudinal slot 31 connected to the insertion opening 30, the one Has height, which also corresponds to the height of the stop 27, so that the clamp 25 can be passed through the movable grate bar 2.
  • a special insertion opening as in the embodiment according to FIGS. 1 and 2 is not required here with the movable grate bar.
  • two locking bolts 32 are slidably held on the underside of the clamp bolt 26, the width of which corresponds to the width of the clamp bolt 26 and the height of the protrusion of the hook-like stop 27.
  • the fixed grate bars 1 are then raised so far that the respective stop 27 can be inserted through the insertion opening 30, whereupon the grate bars 1 are lowered, whereby the stops 27 engage behind the outer ribs 13 of the fixed grate bars.
  • Each locking bolt 32 has a longitudinal slot 33 through which a bolt, which is fixed on the clamp bolt 26, extends and which holds the respective locking bolt 32 on the underside of the clamp bolt 26 with a head 34.
  • To move the locking bolt 32 is a double-armed, on the underside of the clamp bolt 26 pivotally mounted tab 35 which is articulated with its ends 32 by means of pivot pins 36 to the S p lock.
  • the pivot pins 36 protrude from the locking bolt 32 and can engage with their projecting ends in locking holes 37 in the clamp bolt 26 when the locking bolts 32 are in the locking position shown in FIG.
  • the tab 35 can be loaded by means of a compression spring 39, so that the tab 35 can move away from the clamp bolt 26 against the action of the compression spring 39, so that the pivot pin 36 do not hit the clamp bolt 26 when pivoting. If the pivot pins 36 engage in the locking holes 37 after pivoting of the tab 35, the tab is held in this position by the compression spring 39 so that the locking bolts 32 are secured in their locking position.
  • a clamp 40 with a round clamp bolt 41 is provided, at the ends of which hook-shaped stops 42 are fastened, one stop of which carries an adjusting screw 43.
  • the design corresponds to that of FIG. 4 except for the round design of the clamp bolt 41.
  • the clamp 40 is locked by rotating the latter after the stops 42 have been pushed through a correspondingly adapted insertion opening 44.
  • the stop is located 42 after rotation by means of a lever 45 fastened to the clamp bolt 41 in a position in which the stop no longer aligns with the insertion opening 44, so that the fixed grate bars 1 can no longer be removed from one another.
  • the ribs 11 and 12 of the movable grate bar 2 each have a longitudinal slot 46 'and 46, wherein in each case a sliding block 47 is arranged in the longitudinal slots 46, which sits on the clamp bolt 41.
  • the sliding block 47 has a rectangular shape and can therefore not be rotated in the longitudinal slot 46, even if the movable li c hen grate bar 2 act forces to the sliding block 47th For this reason, the bracket 40 can not be rotated, so that the locking that has been achieved by twisting. can no longer undo automatically.
  • 10 to 12 show a further embodiment of the clip.
  • This configuration is particularly simple, since the clamp designated overall by 48 has a simple straight clamp bolt 49 with a preferably rectangular cross section, which is provided at its ends with threaded bores 50 into which set screws 51 can be screwed.
  • the set screws can have a hexagon socket for their actuation.
  • they At the opposite end they have conical projections 53 which, in the installed state of the clamp 48, interact with inclined surfaces 54 on the inside of the outer rib 13 of the respective fixed grate bar.
  • the distance between the two fixed grate bars 1 can be shortened by screwing in the set screws 51 more, or increased by unscrewing the set screws.
  • the clamp bolt 49 which has a rectangular cross section in the example shown, is passed through a longitudinal slot 56 in the movable grate bar 2, which is essentially the same as the thickness of the clamp bolt, when installing the grate covering without the set screws 51.
  • the length of the longitudinal slot 56 corresponds to the size of the maximum relative displacement of adjacent grate bars.
  • the set screws 51 are screwed in for installation only so far that the conical projections 53 are flush with the top of the clamp bolt 49, as can be seen from the illustration at the left end of the clamp bolt in FIG. 10. In this position, the clamp bolt with the adjusting screw 51 can be inserted into an insertion opening 55 provided in the outer rib 13, which has the cross-section of the clamp bolt 49 and the set screw 51 projecting downward corresponds. If the set screw 51 is then turned upward so that the conical projection 53 comes to rest against the inclined surface 54, the stop can no longer be pulled out of the insertion opening 55. The clamp 48 is thus locked in its operating position.
  • FIG. 13 and 14 one of the possible embodiments of a clamp for a fixed edge bar 1 'of a fixed grate step is shown.
  • a boundary plate of a fire grate is designated, which is assigned to the edge bar 1 '.
  • a retaining tab 80 is fastened, which has a guide slot 57, which is aligned perpendicular to the grate bar back of the edge bar 1 '.

  • set screws 63 are screwed in, which correspond to the set screws 51 of the embodiment according to FIG. 11. With their conical projections 64, the set screws 63 rest on inclined surfaces 65 and 66 of the outer rib 13 'of the edge bar 1'. If the set screws are screwed further up, the gap 67 between the edge bar 1 'and the limiting plate 78 is reduced.
  • the upper leg 61 is inserted into an insertion opening 68, which is comparable to the insertion opening 55 in the embodiment according to FIG. 11, because this insertion opening 68 is adapted to the upper leg 61 and points In the lower area there is a recess 69, which is provided for the passage of the adjusting screw 63 when it is in its lower position, in which the conical projection 64 does not protrude beyond the leg 61.
