Definitions

  • the invention relates to a finished-part track and the production thereof. Specifically, the invention relates to a finished-part track for an inclined conveyor system for mining trucks in opencast mining.
  • the material to be mined loosened by drilling or blasting (hard stone, compact ores) as well as the waste are transported from the mining sites to the earth's surface by mining trucks, which are heavy goods vehicles built as dump trucks, via the transport routes established between the stopes.
  • mining trucks which are heavy goods vehicles built as dump trucks, via the transport routes established between the stopes.
  • the serpentines getting longer and longer with increasing extraction are thereby travelled upwards at about 10 km/h and downwards at about 35 km/h, which requires extraordinarily high concentration from the drivers, and always bears the risk of serious accidents.
  • inclined conveyor systems are proposed, with the aid of which the mining trucks are conveyed in an empty state to the mining site, and are then conveyed out of the mining funnel in a loaded state.
  • the inclined conveyor system is a mobile platform, which can be moved up and down on an inclined track by way of corresponding tackles.
  • the travel track extending down below with the incline of the mining funnel thereby makes serpentine navigation dispensable, which on the one hand makes working conditions substantially easier, and on the other hand relieves the mining trucks at the same time.
  • a mining truck loaded on the floor of the funnel only needs to be placed onto the lowered mobile platform equipped with locking means for the car wheels, and is then conveyed automatically to the top, where a driver enters the truck for further transport. In this way, a very flexible, economical interplay can be achieved, for which different personnel is on hand at the funnel floor than is on the earth's surface.
  • an inclined conveyor system is installed extending from the edge of the mining funnel, that is, the opencast mine, on the earth's surface to the floor of the mining funnel, starting at an upper edge of the opencast mine.
  • the travel track of the inclined conveyor system is made of prefabricated components.
  • the inclined conveyor system further comprises a conveyor platform that can be accessed by mining trucks, and a counterweight, which runs underneath said conveyor platform in the travel track. In this way, conveyor platform and counterweight travel within the travel track on different tracks arranged in a superimposed fashion, said tracks being provided with rails.
  • a foundation is provided initially.
  • the track system can thereby be assembled starting from the floor of the open pit, or else from the upper edge of the open pit to the floor.
  • this foundation is built from the excavation material at disposal in opencast mines, that is, directly into the walls of the open pit.
  • At least one base element is placed onto the constructed foundation.
  • This base element is formed of at least two base plates, wherein said base plates are spaced apart by at least one cross member, and the base plates are connected to the cross member.
  • This connection of the base plate to the cross member can be done by way of a form-fit and/or force-fit connection.
  • Beneficial are form elements in the connection, which are complemented by screws.
  • both in the base plate and in the cross member preferably metal structures are provided at appropriate locations, which, particularly preferably, are integrally cast. Furthermore, the space provided in the supports for the screw connection (pockets, recesses etc.) can be filled by a grouting with concrete or another suitable material.
  • an adhesion-promoting that is, adhesion increasing intermediate layer from suitable materials between the base element and the foundation.
  • the base element is fixed in place on the foundation by way of anchorages, which can also extend through the foundation into the natural subsurface. At least some of the anchorages can thereby be installed in an overlap area of two adjacent base elements so that the anchors used there anchor both base elements.
  • the anchors When anchoring, the anchors can be mounted on previously prepared structures in the respective base elements, or else these structures are only prepared when installed at the installation site. Preferably, these structures are bores, through which the anchors are driving into the subsurface. However, other structures, to which the anchors can be connected, are also feasible. The number of anchors primarily depends on the weight of the assembly to be anchored and the condition of the subsurface.
  • At least one track element preferably at least two track elements, are placed onto and connected to the base element.
  • the base element can be mounted together with the track elements, wherein in this case, the structures for the anchors can already be present, or they can be prepared at the place of installation, wherein the structures can extend both through the respective track element and through the base element. It is beneficial that the track elements for the two tracks are identical parts so there is no need to manufacture, store, and install different parts.
  • the individual track elements are aligned with one another. Furthermore, the individual faces of work, or possible gaps that developed, both between the adjacent base parts and the adjacent track parts, and the adjacent rails positioned on the track parts, can be filled, and the parts can be coupled in this way. This is particularly beneficial with regard to the rails since vibrations of the conveyor platform, that is, the counterweight can be reduced.
  • connection structures like tension anchors, thread connections, or any other imaginable form-fit, force-locked, or adhesively joined type of connection.
  • the connections, with which cross member and base plate are connected, are also conceivable here.
  • An element of the prefabricated track comprises at least one base carrier, at least one track element, and a plurality of spacer elements, which are arranged between the base carrier and the track elements for the alignment thereof with one another.
  • at least one shear cleat is provided, which is likewise arranged between the base carrier and the track element, and which transfers the static and dynamic stresses impacting the track element to the base carrier/the base element, and thus to the foundation by way of the anchorages.
  • the shear cleats are centered and in conformity with one another, both in the track element and in the base carrier.
  • the surfaces of the shear cleats touching one another can be made without cladding of the material of the base carrier/track element, or, for example, metal plates can be interposed.
  • shear force consoles for the occurring shear forces are provided on the base carrier. These absorb potentially occurring shear forces and transfer them to the foundation by way of the anchorages.
  • the base carrier can also be provided with at least one structure on the two ends pointing to the next base carrier during installation, which allows adjacent base carriers to be connected to one another, preferably by form fit, such that while being anchored to the foundation, the base carrier no longer has to be held by additional structures.
  • the underside of the base elements facing the foundation can be calculably roughened by way of inlaid, that is, attached strips or similar structures molded on the base element, and can be connected to the foundation, that is, the subsurface, by local grouting.
  • shelves can be placed into the developing interspaces between the cross members and the base plates for reinforcement. Preferably, these are geometrically designed such that they are held between the base carriers and cross members by form-fit.
  • the track elements form two levels of different heights on each base carrier, and together with another base carrier in a base element, form two tracks, which, as a result of the differing height levels, are arranged superimposed upon one another, and are formed of two rails each.
  • These rails can be connected to the track element either directly, or by way of interposed structures.
  • the rails are of a two-part design so that an upper part of the rail is connected to a lower part of the rail by a—preferably detachable—connection. Said lower part is detachably or fixedly connected to the track element.
  • the lower part of the rail—or with a one-piece design, the one rail— can be directly cast with the track element.
  • a worn upper part of a rail can be replaced, and no elaborate welding of material on site, for example, is needed.
  • all rails for the two tracks are of the same type and size so that there is no need for different types of rail to be held available at the building site.
  • the spacer elements are arranged between the base element and the track elements such that a space between the two elements can be varied. Furthermore, the spacer elements can be placed such that they are able to transfer the dynamic and static stresses impacting the track part to the base element. Thus, shear cleat can be dispensed with.
  • a spacer element is a trapezoidal thread spindle with fitting nut, that is, threaded sleeve.
  • a spacer element such as this is then inserted into a base carrier, that is, a track element such that it can be adjusted, and the respective screw part can engage with the nut part in the state of assembly of both elements.
  • a base carrier that is, a track element such that it can be adjusted
  • the respective screw part can engage with the nut part in the state of assembly of both elements.
  • any kind of spacer element can be used (wedges, hydraulic presses etc.).
  • the spacer elements allow a precise alignment of the travel tracks for the platform and the counterweight, even with lower installation precision of the base elements.
  • it can be advantageous to relieve the spacer elements, at least partially, by using supports between the track element and the base carrier.
  • the track element can be provided with shear force holders, which, in turn, can carry rope guide pulleys.
  • each track has a dedicated shear force holder and with rope guide pulleys.
  • a central shear force holder is also feasible.
  • Separate rope guides not configured for transferring the shear forces are feasible as well.
  • Possible materials for the prefabricated components are concrete and steel, however, fabrication from composite materials is also feasible, which can also have recycled portions, where appropriate.
  • devices for fastening handrails and stair segments can be provided so that a walkway next to the track can be provided.

  • a conveyor platform 4 which can accommodate a mining truck 3
  • a counterweight 6 travel.
  • the conveyor platform 4 and the counterweight 6 travel on tracks A and/or B, which are arranged superimposed upon each other.

  • FIG. 2 shows the prefabricated component 5 , the primary elements of which are a base element 51 comprising two base carriers 510 (only one is shown) and three cross members 520 (only one is shown), as well as four track elements 52 (only two are shown).
  • the base element 51 is connected to the track elements 52 by way of shear cleats 53 and a plurality of spacer elements 54 , and supports 60 .
  • the spacer elements 54 are anchored both in the base carrier 510 and in track element 52 , thus connecting elements 510 and 52 in an adjustable manner.
  • the spacer elements 54 are configured as trapezoidal spindle lifting units. After adjustment of the spacer elements 54 , the supports 60 relieve the spacer elements 54 , at least partially.
  • the prefabricated component 5 is provided with two tracks A and B, as can further be seen in FIG. 2 .
  • Said tracks A and B are arranged superimposed upon one another so that the counterweight 6 can travel through underneath the conveyor platform 4 when the two meet.
  • the different levels of the tracks come about as a result of the shape of the base carriers 510 , where the fittings (shear cleats, spacer elements, support elements etc.) for the track elements 52 are located on different levels.
  • the track width of the inner and lower track for the counterweight 6 is smaller than that of the track for the conveyor platform 4 .
  • Tracks A and B each are comprised of a pair of rails 55 (shown schematically). In this embodiment, crane rails of type DIN 536 A 150 are used.
  • the prefabricated component 5 has a shear cleat, however, only the shear cleat 53 formed between the base carrier 510 and the track element 52 is shown.

In this way, a static and dynamic stress can be transferred to the respective base carrier 510 of the base element 51 by way of frictional engagement of the two parts 53 a and 53 b.
  • the shear cleats are each centered in the base carrier 510 .
  • the overlap of the two parts 53 a and 53 b of the shear cleat has to be large enough so that even at maximal distance between the base carrier 510 and the track element 52 a sufficiently large overlap surface is available in order to transfer the occurring static and dynamic stresses.
  • the track element 52 is further provided with a plurality of holes 59 , into which the anchors are inserted, which then connect the base element to the foundation.
  • the number of holes 59 and thus the anchors used per prefabricated component 2 , primarily depends on the load to be transferred, the type of anchors, and the subsurface.
  • the holes 59 can already be provided during the manufacture of the prefabricated component, or they can be made at the installation site at the open pit, depending on the number of anchors needed in the particular section.
