Belt transfer device

The innovation relates to a tape transfer device according to the generic term dee Hauptanepruchea

Band transfer devices of the type mentioned Bind in general known and used in coal mining to bapu the coal requested by the belt feeder over the To bring BandQbergabarinne to a lower level.

Such belt transfer channels consist of hard-clad, appropriately cut single sheet metal sections, the partially cylindrical lüalzdeformung in the shape of a channel and then they are all joined together to form a channel curve by flange connection of the Rbands of the individual sheets cuts.

On the one hand, this is relatively simple in terms of production technology but on the other hand this has a gutter curve as a result, whose idandung is not continuous, but has several kinks or discontinuities each according to the number of assembled individual sheet metal blanks.

This prior art design has two disadvantages, namely on the one hand, higher wear and tear on the bulk goods side hard-clad gutter sheets at the kink areas and on the other hand a "wear and tear" of the conveyed material itself in the sense that a relatively large amount is inevitable due to the discontinuous slide Fine coal is produced, which is usually not desired will·

Of the . Accordingly, innovation lies in the task that has obviously not yet been recognized in this special context based on a band transfer channel of the type mentioned to the effect that the two wear loads of the above kind avoided bzu. can be largely reduced.

This task is accomplished with a tape transfer device of the type mentioned according to the innovation resolved what is covered in the characterizing part of the claim.

This problem can also be achieved in another way, namely according to the characterizing part of the dependent claim · 2.

Uie eich has shown, performs this very simple, but with a certain additional effort (additional compression deformation) to the solution to be realized according to claim 1 to the th result, which is also a considerable overall

insofar has economic significance, all other Calculations have shown that loss reductions in the entire German de-mining industry are of the order of magnitude from 7-8 million DM results, üleichee applies to the solution according to the next door 2, which is more advantageous in that such a channel is composed of only three sheets of metal can·

The * ■ new belt transfer device

The following is based on the graphic representation explained in more detail.

Ee shows schematically 1 shows a side view of a tape transfer device

with the usual curvature; Fig. 2 is a front view of the channel, . 3 shows a side view of a tape transfer channel according to

\ the innovation;

FIG. K shows a sheet metal blank for a channel according to FIG. 3; Fig. 5 is a front view of another independent exterior

guidance of the transfer channel;

Fig. 6 shows the channel according to Fig. 5 in side view and FIG. 7 shows a particular embodiment of the channel in FIG Cut.

The application and arrangement of such tape transfer devices let illustrated in Fig, 1 · The single sheet accessory of the individual segments 2 represent plate surfaces of cylinders with the same diameter, εο daQ trained in this way when assembling Individual segments in the course of the recognizable curvature G resulted in discontinuous knots 7 * in the course of the entire channel.

In the tape handing over the gutter trough sheet 5 or, according to FIG 3 · aind such kinks 7 ¹ ziiiar avoided and in that the Einzeleegmente Z BZU. the individual sheet metal blanks in question are no longer sections of cylinders with a straight axis, but of ring cylinders, that is, the radius of curvature 3 of the channel edges corresponds to the radius of curvature i * of the entire arc of the channel 5

In consideration of the advantages that can be achieved with regard to the reduction of wear and tear on both the gutter ax The additional production work is also required on the material to be conveyed (hard coal) (additional compression deformation) justified.

iilie sue Flg. k recognizable, the connecting edges of the sheet metal blanks of the surfaces 1 are formed as curves running in the sense of the resulting spherical curvature.

Eirra other solution with dsm same beneficial effect beds according to Fig. 5-7 in the fact that this is the channel bathing 11 formed from one piece and this accordingly the curvature of the Rinnenbagene, i.e., even the slightest AnechluBepaltB, which is still at the execution form of Fig. 3 result, fall here path.

To the connecting edges β of the curved bottom 11 The sides are simply, uie recognizable, accordingly curved cut side boundary flank plates arranged and connected to the ground in suitable tracks.

Uie bub Fig. 7 recognizable, the connection: - ~ bovine β dee Baden 11 designed as a curved RSnder Io so that even longitudinal gussets 12 can be avoided.

Of course, it is also possible to use the connectors the two side delimitation flank plates 9 instead of deforming the Röncier of the bottom 11 accordingly.
