Definitions

  • the present invention relates to a device and a method for filling a trough with solid conveying material or for transporting solid conveying material out of a trough.
  • open-cast mining mineral resources are extracted from layers near the surface, such as ores, stones, sand, gravel or coal.
  • the excavation is carried out with excavators, bucket wheel excavators, by blasting, milling, etc.
  • the material obtained is often transported from the mining site to the processing site for further processing.
  • Open-cast mines can also reach great depths, which can make transporting them away with conveyor belts, in particular, because the conveyor belt often has to be moved and adjusted in length.
  • conveyor belts can be used as conveying devices for conveying the conveyed material, with a driven, endless conveyor belt which is deflected via deflection rollers at the two ends of the conveyor belt.
  • a large number of support rollers are generally provided between the deflection rollers in order to support the conveyor belt, in particular the run in which the material is conveyed.
  • conveyor devices are also known with a conveyor belt on which a plurality of support rollers are arranged distributed over the length, which roll on tensioned support cables. Examples of this can be found in EP 2 460 744 B1 or EP 2 030 919 B1.
  • a known aerial cableway designed as an aerial tramway for transporting conveyed goods such as e.g. Bulk, can be used.
  • a material bucket for receiving the conveyed material is arranged on a hanger on the aerial tramway.
  • the hanger is suspended on a carrying rope (or several carrying ropes) with a carriage with a number of idlers and is usually moved back and forth between two stations with a pull rope attached to the carriage.
  • the opencast mine sometimes leaves very large and / or deep hollows in the landscape. It is often the wish or requirement to refill such troughs with material after the mine has been left open, for example because the deposit is exhausted.
  • troughs to be filled can of course also be created in a manner other than the extraction of mineral resources.
  • the filling of troughs is also often carried out with conveyors in order to transport the filling material to the right place. This is also complex, because the conveyor system often has to be implemented and its length adjusted. The above-mentioned conveyor systems can also be used for this.
  • This object is achieved according to the invention with at least one support rope that is stretched between two guy points over the trough and that sags between two support points in the form of a rope line, a conveyor device for conveying the conveyed material being suspended on the at least one support rope, the Anchoring points are each arranged above a desired filling level in the area of the respective anchoring point and a suspension cable length of the at least one suspension cable between the two support points is longer than a conveying length of the conveying device between the two support points, and a rope adjustment device for adjusting the suspension cables between at least one suspension point the two bases is provided.
  • the suspension cable can be pulled at certain times in order to shorten the suspension cable length between the two support points, at the same time the at least one suspension cable with the conveyor device suspended thereon is moved upward, or the suspension cable can be released at specific times to reduce the suspension cable length between to enlarge the two bases, at the same time the at least one supporting cable with the conveyor device suspended thereon is moved downwards.
  • the sag of the suspension cable in the trough can be adapted to the trough, so that the conveyor can always be kept at the required or desired distance from the trough base. It is no longer necessary to move the conveying device or guy points or support points, which considerably simplifies the effort for conveying into or out of the trough.
  • a transfer station for loading onto the conveyor device or for unloading from the conveyor device is preferably provided in the area of a guy point and the cable adjustment device is provided at the guy point opposite.
  • the end of the suspension cable can thus be adjusted, on which the conveyor is not suspended, where an adjustment of the suspension points of the conveyor on the suspension cable, which might otherwise be necessary, can be avoided. This simplifies the use of the device.
  • a distributing conveying device can be suspended from the at least one supporting cable in the region of an end of the conveying device lying in the trough, the conveying device conveying the conveying material onto the distributing conveying device.
  • the distribution of conveying material in the trough can be easily adapted to the respective requirements and conditions by appropriately designing the distribution conveyor. It is particularly advantageous if the distribution conveyor is designed as a distribution conveyor belt that can be operated in both directions of conveyance. This can be used to easily convey material be unloaded at two different locations in the trough, which supports the further distribution of the conveying material in the trough.
  • FIGS. 1 to 6 show exemplary, schematic and non-limiting advantageous embodiments of the invention. It shows
  • FIG. 1 shows a cross section through a trough with a support rope stretched over it
  • FIG. 2 shows an embodiment of a conveying device for conveying into and / or out of the trough
  • 3 shows one end of the conveying device in the region of an anchoring point of the suspension cable
  • 4 shows one end of the conveying device in the trough

  • the width and length, or roughly one diameter, of the trough 1 can be in the range of a few hundred meters, smaller and larger dimensions also being conceivable here.
  • the trough 1 has a trough base 2, from which the trough slope 3 extends all around with a slope angle upwards. It goes without saying that the trough 1 does not have to be symmetrical, nor does it have to have the same angle of repose on all sides.
  • the trough slope 3 can also be designed in the form of steps.
  • the shape and dimensions of the trough 1 are ultimately secondary to the invention. Conveying material is transported onto the trough bottom 2 for filling in order to fill up the trough 1, as a result of which the trough bottom 2 rises. Conversely, conveyed material obtained in the trough 1 is transported away from the trough bottom 2, the trough bottom 2 being able to sink further.
  • At least one suspension cable 4 is tensioned over the trough 2 between two guy points A1, A2.
  • Several support ropes 4 can also be tensioned, the number of support ropes required of course depending on the span and the load to be carried.
  • the at least one support cable 4 hangs over the trough 1 between two support points SP1, SP2 in the form of a cable line, which results in a support cable length IT as the length of the cable line between the two support points SP1, SP2.

  • a support 5 (or more) for the at least one support cable 4 can also be provided at a suitable point.
  • the support points SP1, SP2 are preferably arranged above the desired filling height hv in the area of the respective support point SP1, SP2, that is to say at a higher level.
  • the backfill height hv is the level of the trough bottom 2 after backfilling.
  • the backfill height hv corresponds to the starting height, that is to say the bottom 2 of the trough at which the dismantling begins.
  • a base SP1, SP2 could, for example, be arranged lower than the other base SP1, SP2 and also lower than the filling height hv in the region of the other base SP1, SP2, but the lower base SP1 is nevertheless preferably higher would be as the backfill height hv in the area of the lower base SP1. It can thus be achieved that the at least one supporting cable 4 always runs above the respective trough base 2 without providing any further supports. Depending on the topology of the trough, it is therefore not absolutely necessary to aim for horizontal backfilling.
  • the support cable 4 sags more or less far between the guy points A1, A2 and there is a maximum sag.
  • An upper tensioning situation S1 is shown in FIG. 1, in which the suspension cable 4 sags only slightly and in particular runs above the filling height hv.
  • the suspension cable length IT is larger and the suspension cable 4 therefore sags further, in particular just above the trough bottom 2, usually in the range from a few meters to a few tens of meters.

  • a drive 20 for the deflecting roller 19 is also indicated in FIG.
  • support rollers 21 can also be arranged in the area of the transfer station U, for example on a support 5, in order to guide a conveyor belt 16 in a targeted manner, for example horizontally in one section, in order to facilitate the handling of the conveyor material in the transfer station U. - tern.
