Definitions

  • the present invention relates to a drivable movable conveyor system for transporting a material, such as mined ore or overburden.
  • the present invention also relates to a support frame for a drivable movable conveyor system and for a manually moveable, i.e. shiftable, conveyor system for transporting a material, such as mined ore or overburden.
  • the present invention has particular, although by no means exclusive, application in the mining industry. Background
  • Conveyor systems are used in industry for conveying a wide range of materials.
  • a conveyor system typically comprises one or more loading points at which materials are loaded onto an endless belt and a discharge point generally at a head of the conveyor system at which the materials are discharged from the belt.
  • flat belt conveyors are used to convey a significant amount of material between locations at relatively high speeds.
  • Such conveyor systems tend to be positioned to transport material in a straight trajectory since bends can, due to the speed of the belts and inertia of the material thereon, create points at which material is inadvertently discharged from the belts. Bends also result in movement of the material towards one side of a flat belt. This movement results in a greater rate of wear of one side of the belt, being the side to which the material is biased when passing around bends, when compared with the other side of the belt.
  • An additional issue inherent in flat belt conveyors is the generation of dust resulting from air dislodging particles of the material as it is carried along the flat belt.
  • Pouch or “closed” conveyor systems have been proposed as an alternative to flat belt conveyors.
  • the pouch belts of these conveyor systems are in an open condition during loading of material onto the belts and are in a closed condition to contain the material in a closed "pouch” whilst conveying the material to discharge ends of the systems.
  • the present invention provides an alternative conveyor system to known systems that has particular, although by no means exclusive, applications in the mining industry that include, by way of example, transporting mined material within a mine pit and transporting mined material from a mine pit to a processing plant or a stockpile in a mine.
  • a drivable moveable conveyor system for transporting a material, the conveyor system comprising:
  • a support frame comprising at least one support module . for supporting the belt so that the conveyor system is flexible along at least a portion of the length of the conveyor system;
  • a drive connected to the support frame for driving the conveyor system in a controlled way in any one or more of a forward direction, a rearward direction, and a lateral direction; and
  • a controller for controlling the drive.
  • the above drivable conveyor system of the present invention is (a) movable in the sense that it can move in any one or more of a forward direction, a reverse direction, and a lateral direction in a controlled way and (b) flexible in the sense that it can allow such movement, for example, while the conveyor system continues to transport material on the conveyor belt.
  • the drivable conveyor system of the present invention may commence operation with the discharge location and the loading location quite close together and with the loading location moving progressively away from the discharge location as the conveyor system tracks behind an excavator (or other mining equipment) that is picking up mined material from a mine pit or removing mined material from a stockpile.
  • the conveyor system is initially set up in a curved arrangement with one or more curves to accommodate the initial closeness of the discharge and loading locations and progressively straightens out, i.e. becomes more linear, as the loading location of the conveyor belt tracks away from the discharge location of the system.
  • This movement of the conveyor system requires flexibility in a controlled way along at least a portion of the length of the system.
  • the drivable conveyor system of the present invention contrasts with conveyor systems known to the applicant in which relocation is confined to either (a) manually shifting skid- or wheel-mounted conveyor systems or (b) disassembly and decommissioning of conveyor systems, relocation of the disassembled parts of the conveyor systems, and reassembly and recommissioning of the conveyor systems in the new locations.
  • the flexibility of the conveyor system of the present invention and the controller of the drivable conveyor system of the present invention make it possible to move the conveyor system in a controlled way.

  • the conveyor belt may be a flat belt.
  • the conveyor belt may be a pouch belt in a closed or open condition.
  • the pouch belt may be the pouch belt described in the Australian provisional application of the applicant lodged on the same date as the subject Australian provisional application. The disclosure in the patent specification of that other Australian provisional application is incorporated herein by cross-reference.
  • the pouch belt may be any other type of pouch belt.
  • the drive may comprise a plurality of drive modules at spaced intervals along the length of the belt for driving the conveyor system in a controlled way in any one or more of the forward direction, the rearward direction, and the lateral direction.
  • the drive may comprise a loading vehicle at the forward end of the conveyor system for driving the conveyor system in a controlled way in the forward direction and in the rearward direction.
  • the drive may comprise any other suitable means connected to or coupled to the support frame that is capable of driving the conveyor system in a controlled way in any one or more of the forward direction, the rearward direction, and the lateral direction.
  • the support frame may support the belt so that the conveyor system is flexible along the whole of the length of the conveyor system.
  • the support frame may comprise a plurality of support modules coupled together along the length of the belt.
  • the support modules may be coupled together to allow vertical and horizontal displacement between successive support modules so that the conveyor system can accommodate changes in the terrain over which the conveyor system travels.
  • Each support module may allow horizontal displacement of the module along the length of the module.
  • Each support module may not allow displacement of the module in any direction other than horizontally.
  • the support frame may comprise a plurality of the support modules and a plurality of the drive modules coupled together along the length of the belt.

  • the drive modules and the support modules may comprise any other suitable arrangement of modules.
  • the drive modules and the support modules may be coupled together to allow vertical and horizontal displacement between the modules so that the conveyor system can accommodate changes in the terrain over which the system travels.
  • the controller may control the conveyor system to increase or to reduce an effective carrying distance of the conveyor system.
  • effective carrying distance is understood herein to mean a distance in a straight line from where material is loaded onto the belt to where it is discharged from the belt.
  • a reduction in the effective carrying distance means, in effect, that the trajectory of the conveyor system includes one or more curves that reduce the straight line distance between the loading and discharge locations.
  • the conveyor system is a flexible conveyor system.
  • the controller may selectively control the drive modules to form one. or more curves in the conveyor system, thereby reducing the effective carrying distance of the conveyor system.
  • the controller may control the drive modules to form one or more straight sections in the conveyor system, thereby maximising the effective carrying distance of the conveyor between successive drive modules.
  • Each support module may comprise a segmented beam that comprises a plurality of spine segments that are coupled together.

  • the spine segments of each support module may be pivotally connected together so that there is no movement of the support module in a vertical plane, no torsional movement of the support module about a longitudinal axis, and limited movement of adjacent segments in a horizontal plane.

  • the embodiment of the drivable movable conveyor system 10 (hereinafter referred to as "conveyor 10"), as shown in Figure 1 , is suitable to convey material, such as a mined ore.
  • FIG. 6 An example of the use of the conveyor 10 in a mine is shown in Figure 6.
  • the Figure shows the conveyor 10 used to transfer mined material from a loading location 12 to a discharge location 14 positioned proximate a stockpile 68 to form the stockpile 68. This is not the only possible use of the conveyor 10 within a mine.
  • the conveyor 10 comprises: (a) an endless conveyor belt 16 for conveying material from the loading location 12 to the discharge location 14,
  • the drive modules 20 and the spine modules 32 of the support frame 18 are coupled together to form a flexible conveyor 10 along the whole length of the conveyor 10.
  • the drive modules 20 drive the conveyor 10.
  • the conveyor 10 is a flexible conveyor in that the trajectory, i.e. the pathway of movement, of the conveyor can be selectively changed between a straight trajectory and a curved trajectory via the operation of the controller as the conveyor continues to operate to transport material on the belt 16 and the conveyor moves within the mine.
  • the controller controls the drive modules 20 to control an effective carrying distance of the conveyor 10.
  • the effective carrying distance for the conveyor shown in Figure 6 is the straight line described by the letter "L".
  • one of the loading locations 12 and the discharge location 14 needs only be moved away from the other. If there are bends in the conveyor 10, they will straighten in a controlled way as discussed below thereby increasing the linearity of the conveyor 10 (i.e. how closely the conveyor 10 approximates a straight line).
  • Extending the effective carrying distance of the conveyor 10 requires that the conveyor 10 have sufficient tensile strength and structural integrity to permit movement by, for example, a tracked vehicle or a loader (not shown) during a period of continuous mining along a wall and that the conveyor 10 be constructed to be flexible and to allow controlled movement of the conveyor via the controller. Contrastingly, when reducing the effective carrying distance of the conveyor 10, the linearity of the conveyor 10 necessarily reduces and the conveyor 10 has a more curved trajectory. As above, it is important that the conveyor 10 be constructed to be flexible and to allow controlled movement of the conveyor via the controller. If this movement of the conveyor 10 is not controlled, the conveyor 10 will rearrange itself by forming bends in an uncontrolled manner.
  • the drive modules 20, one of which is shown in Figure 2 are independently controllable to move the conveyor 10 laterally and create curves in the conveyor 10.
  • the curves maintain a substantially stress-free operation of the conveyor 10 whilst reducing its effective carrying distance.
  • the control of the drive modules 20 is achieved by a controller for performing control sequences as described in relation to Figures 7A to 7D.
  • the controller may be any suitable controller.
  • each of the drive modules 20 is controlled for movement independently of the other modules 20.
  • the drive modules 20 may be in a master/slave relationship with one of the modules 20 being a main module and the other modules moving in response to the main module in a controlled way.
  • movement in general of the conveyor 10 is controlled by an operator located on the mobile stacker 66.
  • control signals may be sent via a wireless link or via hardwiring.
  • the conveyor 10 may be entirely remotely controlled, in which case, a wireless based control system would be used.
  • the drive modules 20 may take any appropriate form as necessary to support and provide mobility to the conveyor 10.
  • the drive module 20 includes a belt frame 22 and assemblies 24 of rollers 26 depending from the belt frame 22.
  • the rollers 26 support both a forward run 28 of the belt 6 and a return run 30 in vertical spaced apart relationship.
  • the invention is not confined to this arrangement and, for example, the forward and return runs may be positioned side-by-side in the same horizontal plane.
  • the rollers 26 also ensure the smooth running of the belt 16 and, for pouch conveyors belts (such as belt 16 as shown), the arrays 24 also ensure the belt 16 remains in a closed pouch configuration when required. It is noted that the invention also extends to other types of belt, including flat belts. In addition, it is noted that the invention is not confined to arrangements in which the belt 16 is in an upper orientation in the return run of the belt shown in the Figures.
  • each spine module 32 comprises a series of spine segments 34.
  • the spine segment 34 at each end of each spine module 32 is coupled with a drive module 20 by a coupling 36 (one part of which is shown in Figure 2).
  • the coupling 36 allows rotation of the spine module 32, relative to the drive module 20, in a vertical plane (i.e. about a horizontal axis).
  • the present coupling 36 is arranged as discussed below, not to allow rotation in any plane other than a vertical plane (i.e. does not allow lateral or torsional angular displacement).
  • the coupling 36 includes a pair of plates (not shown) fixed to the belt frame 22 of the drive module 20 (e.g. via welding) and disposed in a substantially vertical plane.
  • the spine segment 34 coupled with the drive module 20 is provided with a sleeve (not shown - similar to sleeve 58 shown in Figure 4, though rotated through 90°) through which an axle bolt 40 (not shown) extends.
  • the sleeve, and thus the spine segment 34 rotates about the axis of the axle bolt 40 to achieve rotation in a vertical plane. This rotation allows the conveyor 10 to travel along a path that has a changing incline relative to a horizontal plane.
  • couplings 36 enable the conveyor 10 to adapt to changing inclines, it will be appreciated that the ground underneath each drive module 20 may have a slope in more than one direction.
  • the drive modules 20 are adapted to maintain the belt frame 22 in an upright condition. An upright condition of the belt frame 22 also ensures the belt 16 travels in the rollers 26 with consistent orientation, thereby ensuring consistent wear of the belt 16 and consequently increasing its longevity.
  • the drive modules 20 are provided with an undercarriage (not shown) that may be moved by a pair of caterpillar tracks 44 and is pivotally mounted to a chassis 46.
  • the belt frame 22 is also pivotally mounted to the chassis 46.
  • the combined effect of the pivotal mountings is that the undercarriage can be moved into a stable position on the ground while the chassis 46 remains parallel or tangential to the trajectory of the conveyor 10.
  • the pivotal mounting between the belt frame 22 and the chassis 46 then allows the belt frame 22 to pivot to an upright condition in line with the trajectory of the conveyor 10.
  • pivotal connections can be provided and controlled using any appropriate mechanism.
  • the pivotal connection between the chassis 46 and belt frame 22 involves a set of cylindrical bearings (not shown) mounted to the chassis 46 and shaped to receive a shaft 48 mounted to the belt frame 22.
  • the shaft 48 pivots in the bearings resulting in rotation of the belt frame 22 relative to the chassis 46.
  • Pivoting of the belt frame 22 is controlled by a set of hydraulic struts 50.
  • the belt frame 22 pivots about a horizontal axis relative to the chassis 46, and pivots (with the chassis 46) relative to the undercarriage about a vertical axis.
  • the drive module 20 moves by operation of the caterpillar tracks 44.
  • the caterpillar tracks 44 are separately operable in a known manner by drive motors 51 , which drive motors 51 may be locally or remotely controlled. Since each caterpillar track 44 is provided with a separate drive motor 50, the caterpillar tracks 44 can be independently driven to move the drive module 20 forward, in reverse, laterally, or to rotate the undercarriage on the spot without affecting a change in orientation of the belt frame 22 (e.g. driving the caterpillar tracks 44 in opposite directions will cause rotation of the undercarriage in one direction, whilst pivoting the undercarriage relative to the chassis 46 in the opposite direction) at the same rate, resulting in no movement of the chassis 46.
  • While the drive modules 20 can be provided with a single drive motor 51 , such a configuration is not as flexible as a configuration employing two drive motors 51 , since the undercarriage and consequently the drive modules 20 can rotate on the spot.
  • the capability to rotate on the spot serves to reduce the complexity of the control of the drive motors 50, as control algorithms need not account for a minimum turning radius when determining how to arrange the drives modules 20 to adjust the trajectory of the conveyor 10.
  • a spine module 32 as shown in Figure 3, comprises a series of spine segments 34 which are coupled together to form a segmented beam. Adjacent spine segments 34 can pivot relative to each other, typically to a limited degree only, in a generally horizontal plane, i.e. about a vertical axis, by pivotal connections 54 similar to couplings 36 as described above in relation to Figure 2.
  • Each spine segment 34 comprises a belt support frame 49, to which is mounted two sets 52 of rollers 26 for supporting the belt 16.
  • One set 52i of rollers 26 supports the forward run 28 of the belt and the other set 52ii supports the return run 30.
  • rollers 26 in each set 52 will depend on the nature and configuration of the belt 16.
  • the sets 52 may comprise a plurality of rollers 26, Contrastingly, if a flat belt were used instead of the pouch belt 16, the rollers 26 may be replaced with idlers or another suitable arrangement.
  • each coupling 54 comprises a pair of parallel plates 56, each plate 56 being connected at one side to a spine segment 34 and is rounded at the opposite side.
  • An adjacent spine segment 34 is provided with a sleeve 58 through which an axle bolt or pin 60 extends.
  • the axle bolt 60 enables the sleeve 58 to pivot relative to the plates 56, thereby affecting an angular displacement between adjacent spine segments 34 in a generally horizontal plane.
  • the coupling 54 includes bearings 62 mounted at either end of the axle bolt 60.
  • the couplings 54 substantially prevent any angular displacement between adjacent spine segments in any plane other than the horizontal plane. It will be appreciated that many different coupling systems may be employed and are intended to fall within the scope of the present disclosure.
  • the couplings 36 between spine segments 34 and drive modules 20, and the couplings 54 between adjacent spine segments 34, are designed so that the angular displacement permitted by each coupling 36, 54 is at most an angle that would achieve a minimum radius of curvature of the belt 16 in either a horizontal or vertical plane, as appropriate.
  • the minimum radius of curvature will depend on the properties of the belt 16 (e.g. the size, speed of travel, flexibility and configurations such as a flat or pouch configuration).
  • each coupling 36, 54 can be limited by any appropriate means.
  • the drive module 20 may be shaped to come into abutment with the spine segment 34 with which it is coupled when that spine segment 34 has reached a maximum desirable angular displacement with respect to the drive module 20 (for example, it may not have a rounded side as described above).
  • a similar arrangement may be used between adjacent spine segments 34.
  • a hydraulic system (not shown) may be used to hydraulically control the degree of relative rotation of adjacent spine segments 34.
  • a conveyor 10, as shown in Figure 5 can be used to navigate an incline.
  • one drive module 20i is on substantially horizontal ground and a second drive module 20ii is located on the incline.
  • the drive modules 20i, 20ii are connected via a spine module 32!
  • This Figure demonstrates how an angular offset between spine segments 34 and drives modules 20 can result in a conveyor 10 capable of traversing variable inclines.
  • a flexible stockpile conveyor 10, as shown in Figure 6 comprises an alternating series of drive modules 20 and spine modules 32 extending between the loading location 12 and the discharge location 14.
  • the conveyor 10 as shown includes a bend 64, which means the effective carry distance (L) of the conveyor 10 is less than the maximum effective carrying distance (when the trajectory of the conveyor 10 is straight).
  • a stacker 66 representing the discharge location 14, is used to form a stockpile 68i and is connected via conveyor 10i to the loading location 12i.
  • the stacker 66 is initiating a stockpile 68i and thus the conveyor 10i is at full extension (i.e. is at the maximum effective carrying distance at which the trajectory of the conveyor 10i is substantially straight).
  • the stacker 66 can move laterally in an arc, as indicated by the crescent shape of the stockpile 68i. While initiating the stockpile 68i, the stacker 66 may pull one or more drive modules 20 along with it. In this circumstance, the drive modules 20 may be free-wheeling since there is substantially no change in distance between the stacker 66 and loading location 12i. However, ideally the drive modules 20 are driven at all times when repositioning the conveyor 10i, rather than being allowed to free-wheel. This assists in ensuring the drive modules 20 and the spine modules 32 therebetween do not experience non- design stresses. Also shown in Figure 7a is a reclaimer 70, representing the loading location 12, for reclaiming a stockpile 68ii.
  • the reclaimer 70 is linked via a conveyor 10ii to a discharge location 14, for discharging the stockpile 68ii to a train or ship loadout.
  • the conveyor 10il is divided into multiple segments, these being: a loop 72; two parallel sides 74, 76; a length 78 extending from side 74 to discharge point 14ii; and a length 80 extending from the reclaimer 70 to side 76.
  • the parallel sides 74, 76 reduce in length as the effective carrying distance of the conveyor 10ii increases (i.e. more of the conveyor 10ii is required to bridge the distance between the reclaimer 70 and the discharge location 14ii), as shown in Figure 7B.
  • the conveyors 10i, 10H may take any appropriate form to shorten the respective effective carrying distances (e.g. by incorporating two or more such loops) a single loop and two parallel sides as shown in Figures 7a to 7d affords a less complex control algorithm.
  • the length 80 of the conveyor 10ii connected to the reclaimer 70 extends back directly towards the discharge location 14ii - in the present case length 80 extends towards the discharge location 14ii until it is a little over twice the minimum radius of curvature of the belt 10ii from the discharge location 14ii.
  • the belt 10ii curves around an approximately 90 degree angle into side 76 and up and around the loop 72 the size of which is generally defined by the minimum radius of curvature of the belt 10ii.
  • the conveyor 10ii then extends from the loop 72 into the side 74 and back towards the discharge location 14ii.
  • Such an arrangement is simple since any one of the drive modules 20 in the side 74 remains stationary while the reclaimer 70 extends away from the discharge location 14ii, until such time as the effective carrying length of the conveyor 10ii requires a further drive module 20 to migrate around the loop 72.
  • the effective carrying distance of the conveyor 10ii can be determined knowing only its minimum radius of curvature, its length and the length of one of side 74, 76 and length 80.
  • this allows the effective carrying distance of the conveyor to be controlled by determining an appropriate length of one of sides 74 and 76 or length 80, which will result in a consequential proportional adjustment to the other two of sides 74, 76 and length 80.
  • the change in length 80 is equal to the change in length of side 74, plus the change in length of side 76.
  • the change in length 80 is equal to twice the change in length of side 74.
  • the effective carrying distance of the conveyor 10N can be adjusted by changing the length of side 74 resulting in a proportional change in the lengths of side 76 and length 80 accordingly.
  • Figure 7C shows a further iteration in the stacking and reclaiming processes, in which conveyor 10ii is nearly at its maximum effective carrying distance and, contrastingly, the effective carrying distance of the conveyor 10i has been shortened.
  • the effective carrying distance of the conveyor 10 may also change if the loading location 12 and/or discharge location 14 are not fi,xed in position along the conveyor 10. However, such a reduction in effective carrying distance does not directly result in a change in trajectory of the conveyor 10. It will be appreciated that drive modules 20 are required where the trajectory of the conveyor 10 is required to change.
  • the entire conveyor 10 may be driveable, i.e. the entire system can be moved by driving the drive modules 20 together, or the like. It will be understood by persons skilled in the art of the invention that many modifications may be made to the embodiment of the present invention described above without departing from the spirit and scope of the invention.
  • the present invention extends to a method of mining a material comprising mining the material in a mine and transporting the mined material on the belt 16 of the conveyor 10, in the as-mined form or a crushed form, in a mine pit or outside a mine pit to a processing plant or a stockpile of the mine. It is to be appreciated that such an example can be used to transfer the mined material out of the pit using a single, continuous conveyor 10 without the use of haul trucks, or the like.
  • the present invention is not so limited and extends to arrangements in which the conveyor 10 is flexible along a portion (or portions) only of the length of the conveyor 10, with the other portion (or portions) of the conveyor 10 being inflexible.
