Description

WO 2013/024110 Al FLAT HEAD STATION FOR A BELT CONVEYOR SYSTEM DESCRIPTION The present invention relates to a flat head station for a belt conveyor system with a conveyor belt and to a belt conveyor system of this type, on which bulk material can be conveyed in a conveying direction, wherein the flat head station can be arranged at an end of the conveyor belt while being supported on a base and the conveyor belt exerts a belt tension force upon the flat head station. PRIOR ART As an example, Figure 1 shows a flat head station 100 for a belt conveyor system 1 that is known from the prior art and features a conveyor belt 10, on which not-shown bulk material can be conveyed in a conveying direction 12. Depending on its length, the belt conveyor system 1 features a multitude of belt-supporting structures 25 and the conveyor belt 10 can have a length, for example, of several kilometres. In this case, the flat head station 100 is installed at the end of the conveyor belt 10 on a base 22 that may form a so-called planum. The belt tension force to be maintained in the conveyor belt 10 by the flat head station 100 may amount to several tons. In order to support this very high belt tension force by means of the flat head station 100, an anchoring means 21 is embedded in the base 22 and connected via a bracing 26 to a pontoon 27 of the flat head station 100, by means of which the flat head station 100 rests on the base 22. The anchoring means 21 that, as an example, is illustrated in the form of a ground anchor ensures that the flat head station 100 maintains a stationary position on the base 22 despite the high belt tension force engaging thereon and, for example, does not begin to slide opposite to the conveying direction 12.

- 2 A tripper car with a conveying boom can be moved along such a conveyor belt and the bulk material can be unloaded from the conveyor belt by means of the tripper car with the aid of the conveying boom. In this case, the tripper car can be moved over the entire length of the conveyor belt, wherein the tripper car linearly travels along and thusly builds up a heap, onto which the bulk material is unloaded. Once the tripper car has unloaded sufficient bulk material from the conveyor belt on the section along the current position of the conveyor belt, the belt conveyor system with the flat head station needs to be shifted transverse to the conveying direction. For this purpose, it is known to use relocating crawlers that the travel along the conveying direction of the conveyor belt, wherein the conveyor belt can be shifted transverse to the conveying direction by means of said relocating crawlers in accordance with a predetermined offset. Consequently, the flat head station also needs to be laterally shifted such that the anchoring means needs to be removed from the base. The flat head station can also be pulled or pushed in the lateral direction by a corresponding vehicle and the ground anchor needs to be newly embedded in the base at the new position of the flat head station. DE 20 2005 017 878 U1 discloses a flat head station with a ground anchor that serves for supporting the belt tension force introduced into the flat head station by the conveyor belt relative to the base in order to maintain the stationary position of the flat head station on the base. In this case, the ground anchor is realized in such a way that it can be removed from the base and newly embedded in the base after the lateral shift of the flat head station in a simplified fashion. The process of removing and newly embedding the ground anchor in the base is described in that a receiving pit is excavated a certain distance behind the flat head station and the ground anchor is inserted - 3 into this receiving pit. Subsequently, the ground anchor is filled with easily removable material, wherein it is described, as an example, that this material consists of the removed soil. This material is then compacted. In this case, the ground anchor is realized in the form of an open box-type ground anchor and therefore can be removed from the base. Despite the simplified design of the anchoring means, a multitude of work steps are required for removing the ground anchor from the base and newly embedding the ground anchor therein when the flat head station needs to be shifted transverse to the conveying direction of the conveyor belt. DISCLOSURE OF THE INVENTION It therefore is the objective of the present invention to develop a flat head station for a belt conveyor system with a conveyor belt, as well as such a belt conveyor system, which can be shifted laterally to the conveying direction of the conveyor belt in a simplified fashion. Based on a flat head station for a belt conveyor system with a conveyor belt according to the preamble of Claim 1, this objective is attained in connection with the characterizing features. Advantageous enhancements of the invention are disclosed in the dependent claims. The invention comprises the technical teaching that the flat head station features a chassis, by means of which the flat head station can be moved on the base transverse to the conveying direction. Due to the inventive movable design of the flat head station, it can be moved transverse to the conveying direction of the conveyor belt when the conveyor belt is laterally shifted together with the multitude of belt- - 4 supporting structures. To this end, the flat head station is realized without anchoring means, particularly without ground anchor. Significant advantages in the lateral shifting of the belt conveyor system are realized due to the mobility of the flat head station transverse to the conveying direction and the design of the flat head station without anchoring means. The belt conveyor system usually is laterally shifted by means of relocating crawlers that can be moved along the conveyor belt in the conveying direction. Once a relocating crawler reaches the vicinity of the end of the belt conveyor system, at which the flat head station is arranged, the flat head station can be set in lateral motion by means of the chassis in order to likewise move in accordance with the lateral shift of the belt conveyor system. Once the flat head station has reached its new nominal position, it can resume the function of introducing the belt tension force into the conveyor belt without the utilization of an additional ground anchor. For this purpose, for example, the chassis of the flat head station may be easily steerable. In the context of the present invention, the moving direction of the flat head station transverse to the conveying direction of the conveyor belt is any direction other than the longitudinal direction of the conveyor belt, namely the conveying direction of the bulk material. Consequently, the flat head station can be moved with the aid of the chassis by any angle, wherein the angle between the moving direction and the conveying direction may have a value that is greater than 0 0 and smaller than 180, but the moving direction transverse to the conveying direction of the conveyor belt preferably extends at an angle of approximately 9 0 to the conveying direction. The chassis of the flat head station may advantageously feature track sets that extend, in particular, transverse to the conveying direction. For example, the chassis may feature two track sets that are arranged parallel to and - 5 spaced apart from one another and thusly form the chassis of the flat head station. In this case, the flat head station is realized without a pontoon, wherein said pontoon is replaced by the chassis and the track sets. The weight of the flat head station therefore also rests on the track sets of the chassis during the operation of the flat head station. The chassis furthermore may be advantageously realized in a driven fashion such that the flat head station is self propelled, wherein the flat head station may feature, in particular, a preferably electric drive unit. The drive unit may be integrated into the chassis of the flat head station. A power supply of the electric drive unit can be realized with electrical lines along the conveyor belt and the flat head station may be provided with at least one belt drive unit, by means of which the conveyor belt is driven, in particular, with the aid of a driving drum, around part of which the conveyor belt is wrapped. In this way, the flat head station is already electrified such that it is particularly advantageous to utilize an electric drive unit for moving the flat head station by means of the chassis. According to another advantageous embodiment of the flat head station, this flat head station may have an overall mass that is defined such that the flat head station also maintains a stationary position on the base when it exerts the belt tension force, particularly if the flat head station is realized without anchoring means. In this case, the overall mass of the flat head station may be greater than the quotient of the belt tension force and the coefficient of friction p of the base. The coefficient of friction p is defined by the friction pairing between the flat head station and the base, and the friction pairing may be formed by the track sets of the chassis of the flat head station and the base that, for example, may be - 6 composed of the bulk material itself. In this case, the resulting coefficients of friction can have a value, for example, between p=0.3 and p=0.8, preferably between p=0.4 and p=0.7, particularly between p=0.5 and p=0.6. If the frictional force that needs to be overcome in order to laterally shift the flat head station standing on the track sets on the base must be greater than the overall belt tension force exerted upon the conveyor belt by the flat head station in order to ensure the stationary position of the flat head station, the overall mass of the flat head station needs to be greater than the quotient of the belt tension force and the coefficient of friction p. For example, the belt tension force may amount to 30 tons and the conveyor belt is formed by an upper belt and a lower belt that are wrapped around the driving drum. At an overall belt tension force of 30 tons and a coefficient of friction of the base, for example, of p=0.6, the resulting minimum mass of the flat head station with consideration of a safety factor amounts, for example, to at least 60 tons. In order to accordingly determine the overall mass of the flat head station, the flat head station may feature at least one ballast mass. The flat head station may feature, for example, a ballast mass of concrete elements, of metal elements and, in particular, of steel elements, wherein particularly steel has a high density such that the ballast mass has smaller geometric dimensions and therefore can be integrated into the flat head station in a simplified fashion, but it would also be conceivable to utilize concrete elements. Several ballast masses with a different mass can be arranged in the structure of the flat head station in such a way that the resulting overall centre of gravity of the flat head station is approximately arranged centrally between the track sets. This prevents one track set from being subjected to a greater weight load than the opposite second track set.

Another essential feature of the present invention is the structural height of the flat head station because the flat head station should be arranged at an end of a belt conveyor system realized with a tripper car that can be moved along the conveyor belt in the conveying direction. A conveying boom or a conveying bridge with a conveying boom arranged downstream thereof may be positioned on the tripper car. The bulk material removed from the conveyor belt with the aid of the tripper car can be unloaded at a lateral distance from the conveyor belt by means of the conveying boom or by means of the conveying bridge with the downstream conveying boom. Once the tripper car reaches a position adjacent to the flat head station, it may be necessary to transfer the conveying boom or the conveying bridge with the downstream conveying boom from a first belt side to an opposite second belt side. In this case, it must be possible to swing the conveying boom or the conveying bridge with the downstream conveying boom over the flat head station. It is therefore required that the flat head station has a flat structural design with a height that does not significantly protrude over the upper side of the belt of the conveyor belt or the upper side of the belt-supporting structures and maintains at least a vertical clearance from the respective conveying boom or conveying bridge toward the underside. For example, the upper side of the flat head station may approximately end with the upper side of the conveyor belt or with the upper side of the belt-supporting structures of the conveyor belt. The particular feature of a sufficiently high weight of the flat head station for realizing or operating this flat head station without anchoring means only results from the required small height of the flat head station.

- 8 The objective of the present invention is furthermore attained with a belt conveyor system with at least one flat head station and with a conveyor belt, on which bulk material can be conveyed in a conveying direction, wherein the flat head station is arranged at an end of the conveyor belt while being supported on a base and the conveyor belt exerts a belt tension force upon the flat head station, and wherein the flat head station features a chassis, by means of which the flat head station can be moved on the base transverse to the conveying direction. In this case, a tripper car may be provided that can be moved along the conveyor belt in the conveying direction and on which at least one conveying boom or a conveying bridge with a downstream conveying boom is arranged. According to the invention, it is proposed that the flat head station is realized with such a flat design and, in particular, has a vertical dimension that is defined in such a way that it is possible to swing the conveying boom and/or the conveying bridge of the tripper car over the flat head station. PREFERRED EXEMPLARY EMBODIMENT OF THE INVENTION Other measures that enhance the invention are described in greater detail below in connection with a preferred exemplary embodiment of the invention, namely with reference to the figures. In these figures: Figure 1 shows a view of a flat head station for a belt conveyor system with an anchoring means according to the prior art, Figure 2 shows a side view of an inventive flat head station for a belt conveyor system with a conveyor belt, - 9 Figure 3 shows a top view of the inventive flat head station, Figure 4 shows another side view of the inventive flat head station, and Figure 5 shows a schematic illustration of a belt conveyor system with an inventive flat head station and a tripper car that can be moved along the conveyor belt. Figure 1 shows a flat head station 100 at the end of a belt conveyor system 1 with a conveyor belt 10 according to the prior art and was already described in the introductory part. Figure 2 shows a flat head station 100 for a belt conveyor system 1 with a conveyor belt 10, on which not-shown bulk material can be conveyed in a conveying direction 12. The belt conveyor system 1 may be realized with a length of several kilometres and the flat head station 100 is arranged at an end of the belt conveyor system 1, at the opposite end of which, for example, a tail station may be arranged, by means of which the bulk material is deposited onto the conveyor belt. A tripper car, by means of which the bulk material is removed from the conveyor belt and placed, for example, onto a heap, can travel along the conveyor belt 10 between the tail station and the flat head station 100 shown. In this case, the tripper car linearly travels the length of the conveyor belt 10 in that the tripper car moves back and forth along the belt conveyor system 1 between the tail station and the flat head station 100 shown. Consequently, the inventive flat head station 100 according to the exemplary embodiment shown is not intended as a station for transferring material or for depositing material on a base.

- 10 The flat head station 100 particularly represents a station that is mechanically decoupled from the belt conveyor system 1 and preferably serves only for deflecting the conveyor belt 10 and for introducing the belt tension force into the conveyor belt 10. In order to introduce the belt tension force into the conveyor belt 10, the flat head station 100 features a driving drum 24, around part of which the conveyor belt 10 is wrapped. The driving drum 24 may merely serve for deflecting the conveyor belt 10 in the form of an idle drum or the driving drum 24 is driven by a belt drive unit 23 as illustrated in the present example such that the flat head station 100 according to the present invention serves, for example, for driving the conveyor belt 10. In this case, a drive may also be provided in the tail station in order to realize a dual drive for the conveyor belt 10. The conveyor belt 10 is guided in belt-supporting structures 25, of which only one is illustrated in the figure, wherein a multitude of belt-supporting structures 25 may be provided along the conveying direction 12 in the form of a successive arrangement in order to support and guide the conveyor belt 10 without the last belt-supporting structure 25 before the flat head station 100 featuring a direct connection to the flat head station 100 such that the flat head station 100 is realized, in particular, in a free standing fashion. According to the invention, the flat head station 100 features a chassis 13, by means of which the flat head station 100 can be moved transverse to the conveying direction 12. The chassis 13 is essentially formed by two track sets 14, wherein the track sets 14 may be driven by a not-shown drive unit such that the flat head station 100 can move along independently. On its lower side, the flat head station 100 features a running gear 28 that forms part of the chassis 13 and is provided instead of the pontoon 27 - 11 according to the prior art (in this respect, see Figure 1). The drive unit may be integrated into the running gear 28. The driving direction, in which the flat head station 100 can be moved by means of the chassis 13, extends transverse to the conveying direction 12 of the conveyor belt 10 and the chassis 13 features two track sets 14 that extend in the transverse direction referred to the conveying direction 12. In this case, both track sets 14 may be driven individually in order to realize the flat head station 100 such that it is steerable within a certain angular range. Figure 3 shows a top view of the flat head station 100, in which a conveyor belt 10 is arranged on the flat head station 100. The conveyor belt 10 is wrapped around a driving drum 24 by an angle of approximately 180' and the driving drum 24 is connected to a belt drive unit 23 via a gear unit 29. Consequently, the motion of the conveyor belt 10 indicated with the arrows can be realized, wherein this figure shows an illustration of an upper belt and a lower belt, in which the upper belt moves toward the driving drum 24 and the lower belt moves away from the driving drum 24. The chassis 13 of the flat head station 100 features a running gear 28 and track sets 14. The running gear 28 essentially extends between the track sets 14 that are arranged on the running gear 28 parallel to and spaced apart from one another. Due to the chassis 13 provided in accordance with the invention, the flat head station 100 with the driven track sets 14 can be moved in the driving directions 30 shown. The flat head station 100 has an overall mass that is defined such that the flat head station 100, on which no anchoring means 21 are arranged, also maintains a stationary position when the flat head station 100 introduces the belt tension force into the conveyor belt - 12 10. The additional arrangement of the chassis 13 on a flat head station 100 according to the prior art (in this respect, see Figure 1) does not suffice in order to reach the overall mass of the flat head station 100. The inventive flat head station 100 therefore features ballast masses 15 and 16, wherein a central ballast mass 15 is arranged about centrally between the track sets 14 and an additional ballast mass 16 is laterally arranged on the flat head station 100 as a counterweight for the massive belt drive unit 23. In this way, the overall centre of gravity of the flat head station 100 is arranged about centrally between the track sets 14 in order to subject the track sets 14 to equal mechanical loads. Figure 4 shows another side view of the flat head station 100 from the conveying direction, in which the conveyor belt 10 extends, wherein the conveyor belt is illustrated on the driving drum 24 in the form of a sectioned view. The driving drum 24 is rotatably received in a drum bearing arrangement 31 and laterally driven by the belt drive unit 23 with the gear unit 29. The ballast mass 16 is located on the opposite side of the belt drive unit 23 and an electric switching unit 32 is arranged in front of said ballast mass. If the flat head station 100 features two belt drive units 23, an additional mass may already be formed by the second belt drive unit 23 and the ballast mass 16 that serves as a counterweight for the first belt drive unit 23 can be eliminated. On its underside, the flat head station 100 features the chassis 13 with the track sets 14, by means of which the flat head station 100 can be moved in the driving direction 30. According to this figure, the track set 14 is accommodated on the running gear 28 and driven together with this running gear in a not-shown fashion.

- 13 The central ballast mass 15 for achieving the overall weight of the flat head station 100 required in accordance with the invention is located centrally above the track set 14. The flat head station 100 is furthermore characterized by a small height that is defined by the vertical dimension 20 above the base 22. According to the invention, the flat head station 100 is utilized for belt conveyor systems 1 with a tripper car that can be moved along the conveyor belt 10 in the conveying direction and on which at least one conveying boom or a conveying bridge with a downstream conveying boom is arranged. According to the invention, it should be possible to swing the conveying boom or the conveying bridge with the downstream conveying boom over the flat head station 100. The inventive flat head station 100 therefore has a vertical dimension 20 that is defined such that the overall structural height of the flat head station 100 above the base 20 does not significantly exceed the height of the upper point of the conveyor belt 10 on the driving drum 24. Only this makes it possible to swing the conveying boom or the conveying bridge with the downstream conveying boom of the tripper car over the flat head station 100. The arrangement of the flat head station 100 relative to the tripper car is illustrated in greater detail in the following Figure 5 in order to elucidate the arrangement of a tripper car in the belt conveyor system 1. Figure 5 shows a belt conveyor system 1 with a flat head station 100 according to the present invention. The flat head station 100 is located at the end of the belt conveyor system 1 and drives the conveyor belt 10, for example, by means of a driving drum 24 and a belt drive unit 23 cooperating therewith. However, the flat head station 100 may also merely deflect the conveyor belt 10 by means of the driving drum 24, in which case the flat head station 100 would not feature a belt drive unit 23. According to - 14 the invention, the flat head station 100 is not intended for transferring or for unloading the bulk material 11 onto the conveyor belt 10. The conveyor belt 10 therefore reaches the flat head station 100 without the bulk material 11 that was previously removed from the conveyor belt 10 by a tripper car 17. The tripper car 17 can move back and forth along the conveying direction 12 of the conveyor belt 10 in the direction of the arrow shown. The tripper car 17 features a traveling unit 33 that is equipped with track sets 34, but the traveling unit 33 may also move on rails that may be arranged on the belt-supporting structures 25 for supporting and guiding the conveyor belt 10. A conveying bridge 19 is rotatably arranged on the tripper car 17 and can turn about a centre of motion 35 in the direction of the arrow shown. Another traveling unit 36, on which the end of the conveying bridge 19 lies, is located at the end of the conveying bridge 19. A conveying boom 18 is arranged at the support point of the conveying bridge 19 on the traveling unit 36 in order to unload the bulk material 11 that was transferred from the conveyor belt 10 to the conveying bridge 19 and from the conveying bridge 19 to the conveying boom 18. The conveying direction of the bulk material 11 from the conveyor belt 10 to the conveying boom 18 is indicated with arrows. The conveying bridge 19 can swing over the flat head station 100 while simultaneously moving the traveling unit 36, for example, in order to be transferred from a first side of the belt conveyor system 1 to a second, opposite side of the belt conveyor system 1. In this case, the conveying bridge 19 must pass over the flat head station 100 in the direction indicated with the arrow, wherein the flat head station 100 has such a flat design that the - 15 conveying bridge 19 can swing over the flat head station 100 without collision. The realization of the invention is not limited to the preferred exemplary embodiment described above. In fact, a number of variations are conceivable that also utilize the described solution in embodiments of a basically different type. All features and/or advantages disclosed in the claims, the description or the drawings including constructive details or spatial arrangements may be essential to the invention individually, as well as in various combinations. The flat head station 100 may, in particular, also serve for merely deflecting the conveyor belt 10 by means of a drum, wherein the required belt tension force can be simultaneously maintained by the conveyor belt 10. In this case, however, the belt drive unit 23 illustrated as part of the flat head station 100 is eliminated. The base 22 illustrated in Figures 2 and 4 may be realized, in particular, in the form of a planum and the belt-supporting structures 25 for guiding and supporting the conveyor belt 10, the tripper car 17 and the flat head station 100 are located on a level that is defined by the planar base 22. For example, a terrace-like topography of the environment, in which the belt conveyor system 1 is used, may only be predominant in a lateral arrangement and the flat head station 100 is installed on the same level of the base 22 as the belt-supporting structures 25. Consequently, the tripper car 17 can also move at the same height, at which the flat head station 100 can move in the lateral driving direction 30.
