Description

DETAILED DESCRIPTION OF THE INVENTION A support means is provided, in which the support means is constructed as a conveyor belt and is connected to two traction means, which on the other hand are guided by means of a drive. The present invention relates to a tunnel conveyor for underground work.

A mine shaft conveyor, as mentioned at the outset, is a conventional conveyor belt with a conveyor belt resting on rollers at least on the feed side, the conveyor belt comprising a rubber woven fabric as a supporting means and a tensioning means. Consists of cables as. The cable is placed under the support means.
It is generally arranged at the edge and is removably connected and clamped to the support means by means of a groove-shaped or pawl-shaped cross-section formation on the underside of the support means. The support means are slightly concave in accordance with the arrangement of the rollers, but are otherwise relatively rigid and not easily deformable even about the longitudinal axis. The entire shaft conveyor means cannot run in curves. In curved sections, the feed material, for example coal, must be transferred in a laborious manner to the following shaft conveyor. This is not only expensive from a mechanical point of view, but also requires a lot of space. Furthermore, this is a further disadvantage since curves with a small radius of curvature are unavoidable on the feed front according to the geological and structural conditions. Therefore, in practice, shaft conveyors as mentioned at the beginning are not used for mixing.

The unsatisfactory curving performance of the known tunnel conveyors as mentioned in the beginning is based on the following points. That is, in the curved section, the curved outer edge of the support means and the traction means guided there travel a greater distance than the curved inner edge or the traction means guided there.

There must be. The tension means and support means of the known embodiments are therefore unsuitable. Compensation using normal differential gears in automobiles and the like is clearly impossible.

SUMMARY OF THE INVENTION The object of the present invention is to improve the tunnel conveyor for underground work as described at the beginning, so that the shaft conveyor can also run on curves and curves with a small radius of curvature.

In order to solve this problem, the present invention shows the following.

are doing. That is, the pulling means is connected to the longitudinal edge of the support means and is guided in a guide rail of a truck arranged along the feed path, the guide rail being provided for charging the feed material. Support means suspended from the tension means are guided at a distance from each other in the curved area and in the straight section of the feed path to form an open conveyor recess, and the guide rails are spaced apart from each other in the curved area of the feed path. Abutting or substantially abutting each other, the support means suspended from the tension means are guided so as to form a closed or substantially closed conveyor hose. □The present invention is equipped with a support means such that the support means is suspended as described above to form a recess and can be guided together to form a hose. The support means are correspondingly flexible. Said distance differences in the curved sections are eliminated by guiding the corresponding guide rails through the curved sections in a sufficiently narrow and contiguous manner with respect to the tensioning means. The support means then closes to form a hose which passes through the curved area without any reason, possibly forming wrinkles on the inside of the curve. If the guide rails in the curved area are arranged one above the other, the distance difference can be completely eliminated. This is an implementation within the teachings of the present invention. The feature that the guide rails in the curvilinear region of the feed path are guided tangentially or substantially tangentially therefore also includes one-on-one adjacency. At the same time, the feed material is encapsulated in the conveyor hose.

When handling coal, the coal generally has a higher temperature than that of the underground gas that is guided within the mine shaft. For thermodynamic reasons, it may therefore be advantageous to guide the guide rails tangentially or substantially tangentially in this way also in straight sections of the feed path, so that the feed material also Located inside a suspended conveyor hose. The tunnel conveyor according to the invention can directly overcome slopes, so that it may be advantageous to provide a corresponding cross-section on the inside of the support means. These cross-sectional shapes may be omitted if the support means is closed like a hose in the inclined range.

In order to guide the traction means as described above, the traction means can be connected to a roller wheel and thereby guided in guide rails. According to an advantageous embodiment of the invention, it is connected to the edge of the roller wheel support means and can be connected to the traction means of the continuous traction means drive by means of a removable connection, so that when the feed distance is long, , can be operated by a number of intermediate drives, as is also known in shaft conveyors such as those mentioned at the outset.

Various materials are suitable as support means and as tension means. In terms of low weight and long service life even under heavy loads, the following embodiments are advantageous: That is to say, for the tensioning means or supporting means a material is used, a polyamide, in particular a polyamide in the form of Kelvar from DuPont, USA. The support means may be a conveyor belt made of rubber or plastic, which conveyor belt contains the aforementioned material in the form of a textile insert. What is important is that the support means can be suspended and moved within the carriage as a recess or a hose as described above. It is also within the scope of the invention to use suitable netting as support means.

The above-described configuration of the mine shaft conveyor according to the invention relates first of all to the feed side. It is within the scope of the invention to configure the return side accordingly. This is particularly desirable if transport also takes place on the return side, for example transporting the filling.

However, it is also possible for the support means on the return side to be guided so to speak vertically or almost vertically, in which case it is even possible to overcome extremely narrow curves and turns. In this way, the turning position is also simplified in the shaft conveyor according to the invention. The trolley can be mounted or installed at the bottom of the shaft and clamped or locked in the usual manner. This applies both to straight and curved areas of the feed path. However, the trolley can also be mounted in the region of the ceiling or in the region of the side walls of the shaft access. Dropping of the feed material can take place in the usual way on a belt conveyor. However, in the dumping range, the support belt can also be guided as a slope, so to speak, on which sideward dumping of the feed material is possible. For this purpose, it is only necessary to arrange the guide rails with a corresponding offset.

The advantages obtained are as follows. In other words, the shaft conveyor according to the invention can be guided directly through curved sections and narrow curved sections. Large feed output can be obtained without difficulty. Since the conveying material L is continuously distributed over the length of the support means, the support means are not exposed to loads that are large enough to cause disturbances, and in particular the pulling loads are also relatively small, so that the support means as well as having a long service life, and the supporting means can be provided to be deformed to form suspended recesses or suspended hoses as described above without difficulty, or can be guided around curves. . Both kegels and chains can be used as tensioning means.

The tension forces can be reduced by means of an intermediate drive constructed in a known manner.

Embodiments of the present invention will be described below with reference to the drawings.

The illustrated tunnel conveyor is used for underground work. This conveyor is therefore arranged in a feed section, which is not shown for reasons of clarity. The basic configuration includes a trolley 1, tension means 2 and support means 3, which are shown schematically in the figure. The support means 3 is constructed as a conveyor belt and is connected to two traction means 2, which on the other hand are guided via a drive 4. The tension means 2 are connected to the longitudinal edges of the support means 3.

These tensioning means are guided by guide rails 5 belonging to the carriage 1 and arranged along the feed path.

The guide rails 5 have support means 3 suspended from the tension means 2 at a distance from each other in the area provided for the charging of the feed material and, where appropriate, in a straight section of the feed path.
are guided to form an open conveyor recess M. The guide rails 5 are guided in such a way that the support means 3 suspended on the tensioning means 2 form a closed or substantially closed conveyor hose S in the curved region of the feed path, tangentially or substantially tangentially to each other. has been done. The above-mentioned distance differences in curved sections are thereby reduced to such an extent that the desired curved driving ability is guaranteed. Any distance differences that still exist are compensated by elastic deflections of the tensioning means 2 and/or by slackening in the tensioning means 2. The support means 3 are therefore correspondingly flexible and are configured in such a way that, if necessary, a predetermined wrinkle as shown at 6 can be formed in the area of the curved section. Although not shown, the guide rails 5 may also be guided in a straight section of the feed path so as to touch each other or substantially touch each other to form the conveyor hose S. Coal sent within
The conveyor hose S is inserted into a capsule in the entire range between the feed material charging section 1 and the feed material discharge section (2), and prevents heat radiation to the surrounding mine gas.

The tension means 2 are connected in this embodiment to roller wheels 7 and by means of these roller wheels guide rails 5
Guided inside. More specifically, as shown in particular in FIGS. 2 and 3, the roller wheel 7 is connected to the edge of the support means 3 and connected to the continuous tension means drive 4 by a removable connection 8. connected to the tensioning means. Therefore, reference is made to FIG. In other respects, the invention in particular operates using known adjuncts of present day conveyor technology which are referred to in this respect. Although various materials can be used for the tension means 2 and the support means 3, it is advantageous to use the material polyamide. As can be seen from FIGS. 2 and 3, if the support means 3 or the connecting part transmits the introduced tension force, as it were, to the other side of the support means 3, then one of the tension means 2 (
′! It is not necessary. For this purpose, the roller wheels 7 can correspondingly be connected to each other in the conveyor hose area (FIG. 3) and can be fitted into one another, for example by form-locking elements.

As can be seen from FIG. 5, the support means 3 are comprised of a heat-blocking insert 9 and a reflective layer IO integrated into the support means 3.
It is multi-layered with (・ro).

If the return side is closed and becomes a hose, this return side can be used as an underground blast pipe. The air inside the mine may be sucked out through a conveyor hose S.
