    (5) BLOCKS FOR KOLOSNIKOVA GRID FOR REFRACTURES The invention relates to furnace technology and can be used to burn lumpy solid fuel in the furnaces of steam generators. A grate fabric is known, which contains stepped transverse rows of alternating moving and fixed grates with longitudinal ribs made with grooves, interacting with connecting elements, common for groups formed by joint grate SP in each row. The disadvantage of this device is low reliability due to the lack of fixing of the grate in the transverse direction. In connection with this, gaps are formed between the grates, where the fuel particles fall, which leads to an even greater formation of gaps and, moreover, to intensive abrasion of the grates. The purpose of the invention is to increase reliability. WITH A MECHANICAL DRIVE This goal is achieved by the fact that the grooves are made through and in the edges of the moving grates have the shape of the parental slots, and the connecting element is designed as end pins provided with end stops located in the groups of the grates, each of which is formed by one moving and two motionless grates. The stops can be made in the form of protrusions, provided with spacer screws, or in the form of a screw with a conical head, or in the form of a nut mounted on the threaded end of the pin. In the area of the grooves of the ribs of the moving grates, the pins are fitted with bushings and retainers. FIG. 1 shows a canvas (option one), a longitudinal section; in fig. 2 shows section A-A in FIG. ; in fig. 3 canvas option second, longitudinal section; in fig. 4 shows a section BB in FIG. 3; in fig. 5 "ID In FIG. ; in fig. 6 - retainer, wa591205
    execution riant; on . 7 fixed grate; in fig. 8 - moving grate; on (jKir, 9 section GGD in Fig. 7; in Fig. 10 - emphasis, version, variant; in Fig. 11 - section 5D-D in Fig. 10; Fig. 12 - section EE in Fig. 10; Fig. 13 FDA, an embodiment.
    The grate cloth contains stepwise alternating moving rows of alternating moving 1 and fixed 2 grates with longitudinal lower edges, respectively; } but 3 and ii, made with grooves 5 and 6, interacting with connecting elements 5, common for groups formed by adjacent in each group one moving 2 and two fixed 1 grate bars.
    The grooves 5 and 6 are made through, 20 and the connecting element is made in the form of pins 7 provided with end stops 8 and placed in through sections 5 and 6 of each group of grates .W
    The grate bars 1 and 2 are provided at the rear end 9 with grooves 10 for hanging them. The grate -1 is suspended on a fixed support 11, and the grate 2 on the movable support 12. The front end 13 of the grate 1 and 2 rests on the lower row of the grate 1 and 2, to allow the movable grate 2 to move, the grooves 6 are shaped as longitudinal slits .five
    When the grates 1 and 2 are installed in a row between them, a gap is created for the passage of air. The presence of grate 1 and 2 pin 7 with end stops 8 in each group ensures 40 fixing of the grate in the longitudinal direction and a constant width of the gap 1 for the passage of air.
    The end stops 8 are embodied as protrusions 15 (Figs. 2, k, 5 and 9). 4S The passage of the anvil 8 with the protrusion 15 through the slots 5 and 6 is provided by making grooves 5 in the groove 5 and rotating the pin 7 to align the axis of the protrusion 15 with the longitudinal axis of the slot 6 or 6 and making the slots 5 and 6 more than the height of the abutment 8 with a ledge of 15.
    In the first embodiment (Figs. 7 and 11), the pin 7 is provided with a lever 17, by means of which, after the arrival of the stop 8, it pivots through the slots 5 and 6. The side surface of the protrusion 15 rests on the side surface of the rib 3. To prevent the movable grate 2 in the vertical direction in the vertical direction, the pins 7 in the area of the grooves 6 are equipped with a sleeve 18 (FIG. 7 and 9V) In the second embodiment (FIG. K} for fastening the stops 8 with the protrusions 15 after their passage through the grooves 5 and 6 in the working position, the pins 7 in the zone of the grooves 6 are provided with latches 19 (fig. 5 and 6) made in the form of hinged pivots 20 which protrude axles 21 enter the stop holes 22 made in the pin 7. To adjust the width I Zor projection 15 is provided with a threaded hole 23 in which a spacer screw.
    The end stops 8 (yig. 1P) can be made in the form of a screw 25 with a conical head 2b installed in a through-threaded hole 27 made on the ends of the pin 7- The conical head 2b of the screw 25 when tightening the latter passes through the hole 27 and rests its side surface on the side surface of the rib 3 of the stationary wheel 1. Adjusting the width of the gap ik for the passage of air is carried out by the twist depth of the screw 25 in the hole 27. The end stops 8 of FIG. 13) can be made in the form of a nut 28 installed on the ends of the pins 7 of the supply); screw thread 29. The adjustment of the width of the gap 1 is carried out by twisting the nut 28.
    Thus, the reliability of the web is improved due to the rigid installation of the grates 1 and 2 along the transverse axis and the adjustment of the gap 1 for the passage of air, which eliminates the uneven flow of air into the combustion zone, falling into the gaps T of coal, which leads to abrasion of the grates 1 and 2.
