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
- FIG. 6 shows a guy point with an embodiment of a cable adjustment device.
- the invention is described below primarily using the example of filling a trough with conveying material, in particular bulk material. Transport material is removed from a trough in an analogous manner in the opposite direction.
- the trough 1 shows a cross section through a trough 1, which can typically reach a depth in the range from a few tens to a few hundred meters, although of course less troughs or deeper troughs are also conceivable.
- 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.
- the rope line is a function of the span, the arrangement of the support points SP1, SP2 and the load on at least one Support rope 4.
- a support point SP1, SP2 can be an anchoring point A1, A2, for example the anchoring point A2 in FIG.
- the cable length IT between the two support points SP1, SP2 does not have to correspond to the actual length of the at least one cable 4 between the two guy points A1, A2, depending on the specific design.
- the two support points SP1, SP2 coincide with the guy points A1, A2.
- 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 conveyor device 10 is suspended from at least one support cable 4, which is explained by way of example with reference to FIG.
- a total of four support ropes 4 are tensioned next to one another and at least approximately in parallel.
- Suspended from the suspension cable 4 is a first support structure 11 at a first height and a second support structure 12 at a second height.
- a large number of such support structures 11, 12 are arranged at certain intervals along the length of the conveyor belt 10 along the support cable 4.
- the first supporting structure is 11 designed as a U-shaped frame, which is attached to the supporting cables, for example by means of a clamp connection.
- the second support structure 12 is also designed as a frame which is attached to rods or ropes which are in turn attached to the support ropes 4, for example again by means of a clamp connection.
- Two guide elements 13 ', 13 ", 14', 14" are arranged next to one another on the supporting structures 11, 12 in the direction of the longitudinal extent of the conveying device 10.
- the guide elements 13 ', 13 ", 14', 14" are thus also arranged in pairs at different heights.
- a guide element 13 ', 13 ", 14', 14" can be a rope, a rod, a tube, a rail or the like, preferably a rope.
- transverse struts 17 are arranged on the conveyor belt 16 in the longitudinal direction, for example by means of a screw or clamp connection, which protrude beyond the width of the conveyor belt 16 and on the axial ends of which the support rollers 15 ′, 15 “are rotatably arranged ,
- support rollers 15 ', 15 "with different track widths can also be provided on the conveyor belt 16, as in FIG.
- the conveyor 10 can also be designed differently.
- support rollers which are rotatably mounted in the longitudinal direction and on which the conveyor belt 16 is supported can also be suspended on the at least one support cable 4.
- the support rollers can also be arranged on support structures, which in turn are attached to the support cable 4.
- the conveyor device 10 would thus be designed in the form of a classic conveyor belt.
- the conveying device 10 can be designed as a well-known aerial tramway, with a material bucket which is suspended over a hanger with a number of support rollers on at least one support cable 4 or a guide element hanging thereon and can be moved back and forth there.
- the hanger with the material bucket can have its own drive or is moved with a pull rope that is attached to the hanger.
- a transfer station U is arranged in the area of one end of the conveyor device 10 and is arranged in the area of a guying point A1, as shown in FIG.
- the handling station U either conveying material is loaded into the conveying device 10 (when filling), or unloading conveying material from the conveying device 10 (during lifting or dismantling).
- the conveyed material can, for example, be placed on the conveyor belt 16 or filled into a material bucket.
- the conveyed material can be removed from the conveyor belt, for example, or emptied from a material bucket. How the transfer station U, and the loading or unloading, is carried out exactly, is irrelevant to the invention.
- This one end of the conveyor belt 10 in the area of the handling station U is thus also arranged above the desired filling height hv in the area of the guying point A1 or in the area of the handling station U.
- 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.
- the conveyor belt 10 could also extend beyond the guying point A1, depending on the arrangement of the handling station U or the topology of the surroundings.
- corresponding, also stationary, guide elements could be arranged in the area of the transfer station U, on which the support rollers 15 ', 15' of the conveyor belt 16 roll.
- a suitable, known per se, transfer of the support rollers 15 ', 15 "of the conveyor belt 16 from the guide elements 13', 13", 14 ', 14 "of the conveyor device 10 to the guide elements in the area of the transfer station U could be provided ,
- the transfer station U can be provided, for example, in a cable car station into which the material bucket enters.
- the transfer station U, and also the guying point A1 at the end of the conveyor 10 in the area of the transfer station U, can also be provided away from the actual trough 1.
- the conveyor device 10 can also extend further beyond the region of the trough 1.
- a configuration is also conceivable in which the bracing points A1, A2 are provided in the region of the trough 1, but the conveyor device 10 extends beyond a bracing point A1.
- the conveying length IF of the conveying device 10 extending along the at least one support cable 4 between the two support points SP1, SP2 is shorter than the support cable length IT between the two support points SP1, SP2.
- the Conveying length IF of the conveying device 10 between the two support points SP1, SP2 in the range from 20 to 80% of the support cable length IT between the two support points SP1, SP2.
- the deflection roller 22 at this end of the conveyor belt 10 is also arranged hanging on the support cables 4.
- a suitable support structure 23 for the deflecting roller 22 can be provided on the at least one support cable 4.
- the carrying cable 4 extends beyond the end of the conveyor belt 10 to the support point SP2 and guy point A2, which can coincide (as in FIG. 1).
- the conveying material 6 conveyed into the trough 1 by the conveying device 10 is deposited on the trough bottom 2 in the region of the end of the conveying device 10, for example in the form of a pouring cone 24, as in the figures. From there, the conveying material 6 can be distributed on the trough base 2, for example by means of further conveyor belts, an excavator, a bulldozer, or the like.
- the suspension cable 4 is in the lower tensioning situation S2. That the supporting rope 4 is so long that it sags sufficiently far to the trough bottom 2, whereby it is of course to be avoided that the conveyor device 10 hanging on the supporting rope 4 touches the trough bottom 2.
- the conveying device 10 is preferably located a few meters or a few tens of meters above the trough bottom 2. Conveying material 6 is conveyed into the trough 1 by the conveying device 10 and distributed there on the trough bottom 2. This increases the level of the trough bottom 2.
- the support cable 4 is pulled at at least one of the guy points A1, A2 in order to shorten the cable length IT between the support points SP1, SP2.
- the support rope 4 with the attached conveyor 10 moves upward at the same time. This is repeated until the trough 1 is completely filled and the suspension cable 4 is in the upper tensioning situation S1 (FIG. 1). Thereafter, the support cable 4 and the conveyor 10 can also be removed if necessary.
- the conveying device 10 simply moves upward without the suspension of the conveying device 10 at least one suspension cable 4 needs to be changed somewhat. After the suspension cable length IT between the two support points SP1, SP2 is shortened, only the end of the conveying device 10 located in the area of the trough 1 moves in the direction of the anchoring point A2.
- the conveyor length IF does not have to be changed, nor does the position of the anchoring points A1, A2 or the support points SP1, SP2, which considerably facilitates the filling or dismantling.
- tensioning or slackening the suspension cable 4 during this process only the end of the conveying device 10 shifts back and forth somewhat in the region of the trough bottom 2, but this is irrelevant for carrying out the filling or the dismantling.
- the conveyor device 10 hanging on the at least one supporting cable 4 can also be designed in any other way than described using the specific exemplary embodiment, for example with support rollers on which the conveyor belt is supported or with a pendulum track, since this is irrelevant to the invention.
- the at least one support rope 4 is fixed at one of the two guy points A1, A2, thereby changing the support rope length IT at the other guy point A1, A2.
- 5 shows a particularly advantageous embodiment for the filling in the region of the trough bottom 2.
- a distributing conveying device 25 is arranged in a hanging manner on the at least one supporting cable 4.
- the conveyor 10 conveys conveyed material 6 onto the distribution conveyor 25 and is conveyed from there into the trough 1.
- the distribution conveyor 25 is designed as a distribution conveyor belt, although other configurations are also conceivable.
- the distribution conveyor device 25 has two deflection rollers 26, 27, around which an endless distribution conveyor belt 28 rotates. At least one deflection roller 26, 27 is driven by a drive 29.
- the distribution conveyor 25 is designed with support rollers 30 on which the conveying strand of the distribution conveyor belt 28 is supported. Support structures 31 are provided for the support rollers 30 and are arranged on the at least one support cable 4. Corresponding supporting structures 32 are likewise provided for the deflecting rollers 26, 27 and are likewise arranged on the supporting rope 4.
- the distribution conveyor 25 could, however, be designed in the same way as the conveyor 10, that is to say with support rollers 15 ', 15 “, which are distributed along the length of the distribution conveyor belt 28, and with guide elements 13', 13", 14 ', 14 " are arranged hanging on at least one supporting cable 4, preferably on corresponding supporting structures arranged in a hanging manner.
- a common support structure could also be provided for the distribution conveyor device 25 hanging on the support cable 4, on which the components required for the distribution conveyor device 25 are arranged.
- the distribution conveyor device 25 in the form of a distribution conveyor belt preferably extends along the support cable 4 in both directions from the end of the conveyor device 10 in the trough 1 and below the conveyor device 10.
- the conveyor device 10 conveys conveying material 6 onto the distribution conveyor device 25 and is from there promoted in the trough 1.
- the distribution conveyor can move in both directions (as indicated by the double arrow in Fig. 5).
- two pouring cones 24 can be poured onto the trough base 2 with conveying material 6, which of course can facilitate and accelerate the filling. For example, one cone can be filled while the other is being distributed.
- One or more unloading points located between the two ends of the distribution conveyor 25 could also be provided on the distribution conveyor 25, for example in order to fill up further cones 24 or to deposit the conveyor material 6 at other locations.
- the distribution conveyor 25 can only convey in one direction.
- an interchangeable chute can also be arranged between the conveying device 10 and the distributing conveying device 25 which either conveys the conveying material 6 from the conveying device 10 to the distributing conveying device 25, or from the conveying device 10 next to the distributing conveying device 25 directly onto the trough bottom 2.
- the distributing conveying device 25 can also be at a standstill.
- the interchangeable chute could be suspended from at least one support cable 4 or also on a support structure of the conveying device 10 or the distributing conveying device 25.
- the at least one support cable 4 is arranged at the top and all other components, such as support structure 11, 12, 31, 32, guide elements 13 ', 13 ", 14', 14", support rollers, Distribution conveyor belt 25, are suspended from it.
- hanging is understood to be broader, and there are also embodiments in which the support cable is arranged in the center, ie certain components above and certain below the support cable 4, or at the very bottom, ie all components above the support cable 4.
- FIG. 6 also explains an advantageous embodiment of a guy point A1, A2 with a cable adjustment device 46.
- six suspension ropes 4 are provided, the following explanations of course being valid for any number of suspension ropes 4.
- a first holding device 40 of the cable adjusting device 46 is fastened to the supporting cables 4, for example via a clamp connection.
- These first holding devices 40 are supported on a first crossmember 41, through which the supporting cables 4 are passed.
- the first holding devices 40 together with the first cross member 41 must therefore support the entire weight of the support cables 40, the conveying device 10 arranged thereon and the weight of the conveyed conveying material 6.
- second holding devices 43 are provided on the support cables 4, which can be designed in the same way as the first holding devices 40. Furthermore, a second traverse 42, through which support cables 4 are passed, is arranged in a stationary manner, on which the second holding devices 43 can be supported.
- the first cross member 41 is arranged so as to be displaceable in the longitudinal direction of the support cables 4 by means of a drive.
- a linear drive 44 for example a hydraulic, pneumatic or electrical drive, is arranged on a support 45 of the guy point A2, which acts on the first cross member 41.
- Such a linear drive 44 is preferably provided on both sides of the support ropes 4.
- the crossmember 41 can be moved in the longitudinal direction of the support cables 4.
- the embodiment according to FIG. 6 can thus be used as follows.
- the holding device 40 at the ends of the support cables 4 are fastened to the support cables 4 and are supported on the first cross member 41.
- the linear drive 44 is completely retracted. Now the linear drive 44 is actuated, with which the cross member 41 is displaced in the direction away from the opposite guy point A1 - the suspension cable length IT is thus shortened by the stroke of the linear drive 44.
- the second holding devices 43 can also be fastened to the supporting ropes 4, which are thus also moved with the supporting rope 4.
- the second holding devices 43 are released from the supporting cables 4 and moved to the second cross member 42. This can be done automatically or manually. If the second holding devices 43 are detached from the supporting cables 4 when the supporting cables 4 are pulled, then it may also be possible to save the moving of the holding devices 43 to the second cross member 42. Bearing against the second crossbar 42, the second holding devices 43 are fastened to the supporting cables 4 (manually or automatically), with the result that the supporting cables 4 are now supported via the second holding devices 43 and the second crossbar 42. The linear drive 44 can now be retracted again, with the result that the first cross member 41 is also displaced again in the direction of the opposite guy point A1.
- the first holding devices 40 can be detached from the supporting cables 4 and moved in the direction of the first cross member 41 and fastened again to the supporting cables 4 (manually or automatically). Of course, this can be repeated until the desired shortening of the suspension cable length IT has been achieved.
- guy point A1, A2 and / or the rope adjustment device 46 are also conceivable for changing the support rope length IT.
- Another possibility of a cable adjustment device 46 would be, for example, a cable winch for a support cable 4 with a ratchet pawl.
- the linear drive 44 could normally be extended and retracted to extend the suspension cable length IT. In order not to have to always have activated the linear drive 44, one could also provide for a releasable latching of the first traverse 41 in the position of the extended linear drive 44. Alternatively, one could arrange the linear drive 44 differently or provide a different drive.
