    This invention relates to equipment for loading shaft furnaces. The purpose of the invention is to increase the reliability of the tray-type loading device. FIG. 1 shows the device, a cross-section through the suspension of the tray; in fig. 2, section A-A in FIG. one; in fig. 3 - the device, a cross-section similar to FIG. I; on firm. 4 is a sectional view of FIG. 3; in fig. 5, section bb of FIG. 3; in fig. 6 Scheme of the cooling system of the suspension tray. Like in FIG. 1 and 3, the tray 1 is in its upper part located in an annular cradle 2, the lower surface of which encloses the contour in the shape of a truncated cone of tray 1. The suspension bracket fork of tray 1 has the shape of a sealed casing, and the mechanism for transmitting the movement around the Y axis is casing. The upper part of tray 1 is located in a round cradle 2, the inner surface of which exactly corresponds to the shape of a truncated cone of tray 1. In addition, the upper protrusion 3 can be provided on tray 1, entering the groove, made 1Y on the inner surface of the cradle 2. For more securely fixing tray 1 in the cradle 2, for example, to prevent the tray from falling out of the cradle 2 when dismantling the device, you can provide a retaining ring 4 inserted into the slot made on the outer surface of the pot 1, abutting the bottom end of the cradle 2. For To remove the chute 1 from the cradle 2, it is sufficient to cut the ring 4. To the cradle 2, an L-shaped bracket 5 is fixedly fixed, at the lower end of which there is a hole into which the trunnion 6 of the branch 7 of the transfer rod of the inner suspension fork 8 is inserted. also the hole with which it is put on the pin 9 and around which it can freely rotate. The trunnion 9 is part of the suspension fork and is preferably performed on the inner surface of the lid 10, when welded or screwed to the opening 11. The lid 10 is provided with an auxiliary: lid 12 through which you can get i to the hinge connection between the trunnion 6 and the bracket 5 For example, to install or remove the retaining ring of the trunnion 6. A similar and symmetric mounting device is provided between the cradle 2 and the branches 13 and 14 of the suspension fork 8 on the solid side of the tray 1. Thus, the cradle 2 the tray 1 is attached to two pins ax 9 of the suspension fork, and the movement is transformed by bracket 5 into rotation of tray 1 around trunnions 9, i.e., around the U axis. To remove the cradle 2 and the suspension fork 8, a removable fastener is provided between the cradle 2 and each of the two brackets 5 representing a bolt 15. For each side of the cradle 2 there is a flange against which the corresponding flange of the bracket 5 abuts. Both flanges are attached to each other with bolts 15. To provide the necessary rigidity and to avoid rotation of these flanges relative to each other on each flanges have radial teeth 16, which are interconnected. These teeth prevent any accidental rotation of the arm 5 relative to the cradle 2 or vice versa and provide an accurate transformation of movement into the rotation of tray 1 around the axis U without any friction between the arm 5 and the cradle 2 due to insufficient tightening of the bolts 15. Access to the bolts 15 it becomes possible only after removing tray 1 from cradle 2. This advantage ensures a long fastening service life. The connection between the suspension fork 8 and the cradle 2 is made using a round gland 17 or any other suitable element enclosing the bracket 5 at the point of their passage through the inner wall of the branches 13 of the suspension fork 8. Gas or liquid, for example water mixture, can be used for cooling and lubrication and any additives that have lubricating, anti-corrosion and possibly even bactericidal properties. Such fluid is supplied through a clutch in the housing of the suspension fork 8, abutting rotatably against the rear wall of the control system housing. The design may include a rotating connecting nipple 18 connected to one or, preferably, two liquid supply nipples 19 and 20. This fluid then circulates through two tubes 21 and 22 that exit from the sleeve 23, go along the outer walls of the suspension fork 8 and pass through the inside of the furnace between the walls of the suspension fork and the bearing (not shown) so as to follow the rotation of the fork around the axis X. The tubes 21 and 22 pass respectively into both branches of the suspension fork 8 through the hole 24, made in each of the two trunnions 9 coaxially with the axis W. For cooling the cradle 2, it has two internal hemispherical channels 25 and 26, separated from each other at the level of each point Ski partition 27. Each of the channels 25 and 26 associated with
    a hole 24 of the corresponding pin through the internal channel passing through the flanges, with the teeth 16 and part of the corresponding bracket 5. In FIG. 1 shows an internal channel 28 connecting the channel 25 with the tube 22 through the corresponding trunnion 9. On the opposite side, the channel 26 in the same way with the tube 22. An output channel 29 is provided in each of the channels 25 and 26 of the cradle 2 (see FIG. 3) connecting the corresponding channel 25 or 26 with the internal cavity of each of the branches of the plug. The cooling liquid fills the entire inner space: the space of the suspension fork and is removed from it through the coupling 23 and the outlet channel.
    The direction of fluid circulation is indicated by arrows (Fig. 6). The cooling of the cradle 2 of tray 1 and suspension fork 8 greatly reduces the effect of high temperatures on moving parts and ensures a longer service life of the latter. Moreover, since moving parts, -. completely washed with a liquid, they are simultaneously lubricated. In order for the fluid to efficiently perform the function of cooling, it must be cooled if a closed loop is used. FIG. Figure 6 shows the structure with a closed cooling system. At the outlet 30, cooled in the coolant of the heat exchanger 32. Circulation is provided by two pumps 33 and 34, which take the liquid at the outlet of the heat exchanger 32 and feed it respectively to the inlet pipes 19 and 20 through filters 35 and 36 of known design.
    The coolant pressure is adjusted, adapting it to the pressure inside the furnace. This eliminates the pressure difference on both sides of the sealing sapnik and significantly reduces leakage. For this purpose, a pressure equalization device 37 is provided, intended to tighten or reduce the pressure of the coolant depending on the pressure change inside the furnace. This function can be performed by using a device including a diaphragm 38, on one side of which pressure is applied inside the furnace through the filter 39, and the other side is in contact with the cooling fluid. Trunnion 40 identifies a pipeline connecting the cooling system with a coolant reserve to ensure a constant filling of the system.
    The application of the invention enhances the durability of the suspension device of the charging chute of shaft furnaces and contributes to
