The subject of the invention is a carriage that can be moved on the furnace roof for filling the coking coal into Furnace chambers provided with filling openings in the ceiling, in which in telescopically extendable, to the Filling pipes that can be placed on the top of the furnace by means of vertical traction means guided grippers for the filling hole cover run and on the feed pipes for promoting the coal flow serving funnels with them down frustoconical tapering lateral surface are provided, which in the lowered position with its lower The edge rest on the inclined surface of the filling hole frame.

In a previously known filling car of this type, the filling pipes are equipped with a device for suction connected to the filling gases. Such a device, which may clean or burn the Provides filling gases, requires extensive additional equipment and only partially helps to annoy the filling gas away.

There are also known modes of operation for filling cars in which the coal is free during the filling process filling gases - supported by an ejector - are sucked into the gas reservoir. After filling the filler pipe is first removed from a filling hole and the lid is put on, then after- & 5 this process is repeated for the other filling holes. One reckons here that through the Ejector so much filling gas is sucked into the riser pipe that a filling hole can just be kept open, without gas escaping into the atmosphere. This procedure is also cumbersome, time-consuming and prevented the gas nuisance only partially.

It is the aim of the present invention to provide a device that can be moved on the furnace roof and is equipped with filling containers Train wagons in such a way that with as little as possible Equipment expenditure, the furnace chambers filled through all filling openings simultaneously in a short time and in that the gases that are formed inside the furnace chambers when the coal is filled through the feeder be sucked off, any nuisance caused by filling gases is suppressed. The means of which the invention operated, represent raised and lowered hopper with a special design.

According to the invention, these exist within the filling pipes that can be placed on the furnace roof Raisable and lowerable hopper made of several sections that are only connected to one another at the upper edge and give in the raised position for the vertical path of the filling hole cover grasped by the gripper required cylindrical interior of the filler tube free. Means are provided to the sections of the hopper when it is lowered into the position where the lower edge rests on the filling hole frame to bring the required inclination.

These means can either consist of guide bodies which are arranged on the inner wall of the filling pipes are. But you can also press pins in the wall of the lowerable collars of the filler pipes Spread over the perimeter that, when the sections of the hopper get into their area, are moved radially inwards and in this way bring the sections of the hopper into the inclined position, where its lower edge rests on the filling hole frame.

by placing both the sleeves of the filling pipes on the furnace roof and on the outer edge of the felling hole frame as well as the lower edge of the hopper, which can be lowered inside the filling pipes Inclined surface of the filling hole frame come to the sealing support, is a labyrinth-like conclusion of the Füliöcher given during the filling of the coal, which gives the possibility of all filling gases in the gas template deduct. In addition, the funnel that can be raised and lowered also has the meaning of filling to facilitate the coal and to prevent coal from falling on the filling hole frame or next to it.

In the drawings, several embodiments of the new filling car are shown, namely in a cutout showing the lower end of a filling container of such a filling car, which is in the furnace roof shows the intended filling hole and the filling pipe. These are vertical cuts that go through the axis of the filling container and the filling hole are placed, namely shows

F i g. 1 shows a vertical section through a filling truck with a turntable on the bottom of the filling container are,

F i g. 2 shows a vertical section through a filling truck with a vibrating trough at the bottom of the filling container is provided,

F i g. 3 shows a vertical section through a filling truck, in which the filling container can be raised and lowered by a Bell is complete.

The same reference symbols in all figures indicate the same items.

With 16 the furnace roof is designated, in which the filling

Hole 17 can be seen. It is closed by a filling hole cover 5, which is placed on the inclined sealing surface 7 a metallic filling hole frame 8 comes to rest. 5a denotes the filling hole cover in the inserted one Position.

In any case, a FüllbehäUer 1 is provided, its Outlet 15 opens into a filler pipe 2. At the bottom of this there is a collar that can be raised and lowered 3, the outside of the actual filling hole on the furnace roof, if applicable still on the outer edge of the Füllochrahmens 8, can be placed. The cuff is only in the lowered position in all three arrangements shown.

The gripper 4 has to be imagined as electromagnets, which can be raised and lowered by means of a vertical rod 24. they are in the Able to lift the filling hole cover and bring it into a position above the outlet 15 of the filling container. The coal is transported into this outlet with the arrangement according to FIG. 1 through a Turntable 22, in the arrangement according to FIG. 2 by a vibrating chute 23. Dei · filling container 1 after the F i g. 3 has a frustoconical bottom, and the lower opening is closed by a bell 14, which can be raised and lowered.

Within the filler pipes 2 are the raisable and lowerable, forming the subject of the invention Hopper 6 arranged. They are shown pulled out in the lowered position. With 6a they are Hopper in its raised position, shown in dash-dotted lines. Each of these hoppers consists of, for example, four vertical sections 21, which are separated from one another by vertical cuts 18 are separated. In the lowered position, these sections 21 form a downwardly tapering truncated cone and lie with their lower edge 20 on the inclined sealing surface 7 of the filling hole frame 8 on. In the raised position - denoted by 6a - the individual sections 21 hang loosely. Man has to imagine that a pulling device engages at the upper edge 19 of the hopper 6, which the Lowering and pulling back up the hopper accomplished. Between the upper edge 19 and the Inner wall of the cuff 3 sealing elements 12 are provided, which ensure that the falling Coal does not get into the annular space 9 remaining between the filling pipe 2 and the hopper 6.

In the arrangement according to FIG. 1 sit on the inner wall of the filler pipe designed as wedge pieces 10 Guide bodies that move the sections 21 of the hopper inward when they are lowered so that they are in the lowest position join together to form a truncated cone and the lower edge 20 on the inclined surface 7 of the sealing frame 8 rests.

In the arrangement according to FIG. 2 and 3 the inward movement of the sections is carried out by means of pressure pins 11, which are pressed inwards, for example by compressed air cylinders or springs, and in this way bring the sections 21 of the hopper 6 into the required inclined position. Your actuation is expedient automatically in connection with the lowering movement of the hopper.

In the arrangement according to FIG. 3 is the rod 24 on which the gripper 4, which grips the filling hole cover 5, is passed through the bell 14. As shown in FIG. 3 can be seen in the raised Position on the underside of the bell 14.

With 13 sensors are designated, which should respond when the level of coal in the filling container 1 a has fallen below a certain level. There are already pulse generators known that when the filling of the drops Filling container except for a residual amount, which still closes the filling container outlet against the outside air guaranteed, respond and, for example, a pulse to stop the turntable 22 (Fig. 1), for Shut down the vibrating channel 23 (Fig. 2) or to lower the bell 14 (Fig. 3).

Working with the new filling car takes place in such a way that the cuffs 3 are first put on are then lifted the filling hole cover 5 by means of the gripper 4 and then the hopper 6 lowered will. Now either the mechanical conveying device (turntable 22, vibrating chute 23) in Activity set or - see F i g. 3 - the bell 14 raised. After the filling is finished, it remains initially the closure obtained by the coal still in the container. In the case of the arrangement according to FIG. 3 the bell 14 is lowered, in the arrangement according to FIGS. 1 and 2 of the turntable 22 and the vibrating trough 23 shut down. Now the hopper 6 is first brought into its upper position, then lowered onto the filling hole cover 5 by means of the rod 24 of the gripper 4. If the filling hole cover 5 is inserted, so the gripper 4 is raised again and the cuff 3 is raised.
