  • the facility includes, associated with each turntable unit 1 , a respective system for sensing and indicating the rotational position of the turntable and thus the haul truck 209 thereon, fhe system includes a signalling means 21 3, which takes the form of a traffic light to inform a driver of a haul truck 209 of the truck's, position, ' fhe .system further includes means for sensing the position of the haul truck, which shown in Figure 3.
  • LMS Scanner 1 detects the location of a left-hand side of the truck.
  • LMS scanner 2 detects the location of a right-hand side of fhe truck.
  • LMS scanner 3 detects distance of the truck therefrom and thus i.e. how far the truck has been driven onto the turntable.
  • the 'fhe system for sensing and indicating the rotational position of the turntable may use a positioning system such as GPS or XPS to determine a posi tion of the haul truck, relative to the turntable.
  • the positioning system is an XPS positioning system as GPS systems can be unreliable in remote areas.
  • the positioning system includes a transmitter installed in the mine area and a receiver mounted within the haul truck so that the position of the haul truck, relative to the turntable can be accurately determined.
  • Incorporation of an : XPS positioning system into the turntable and haul truck may allow autonomous, or remotely operated trucks to be. used- Use of an indication system with the turntable unit 1 allows the truck, driver, who generally has limited vision from the truck cab, to orientate/position the truck appropriately and accurately on the turntable, thus improving efficiency and safety.
  • a ground surface adjacent the dumping zone 203 may be excavated slightly so that each turntable unit 1 can be installed in the ground so that the upper surface of the deek of the turntable unit 1 is generally flush with the ground, i.e. each unit 1 is countersunk into the ground surface.
  • Each turntable unit 1 may, alternatively, be installed on a ground surface without any such excavation.
  • the units are preferably provided with ramping between the access way and the deck, providing a smooth transition over which the haul truck 209 can be driven onto the unit 1 .
  • ⁇ vehicle unloading facility 301 according to another preferred embodiment of the present invention is shown in Figures 1 1 to 14.
  • the facility 301 includes a plurality of zones 303 for receiving a load carried by a vehicle 309.
  • Each zone 303 is a dumping zone including at least one hopper, chute and/or pit.
  • the facility 301 in this embodiment is a haul truck unloading facility, though, again, in other embodiments the facility may be for unloading oi different vehicles unloadable at a rear thereof, such as any of the alternative vehicles outlined previously.
  • Associated with each zone 303 arc two turntable units 1 disposed adjacent the zone 303, though in a variant of this embodiment there may be only a single turntable unit 1 associated with each dumping zone 303.
  • Also associated with each zone 303 is a first access way 33.1 , from which a. haul truck 309 can be driven forwardly onto the turntable of the respective unit 1 , and a second access way 333 onto which the haul truck 309 can be driven forwardly off the turntable unit 1 .
  • a junction between the first access way 33 1 and the unit 1 is angularly offset, about the turntable axis of rotation, from the dumping zone 303, and the turntable is rotatable with the vehicle standing thereon to bring the rear of the haul truck 309 adjacent the dumping zone 303 for unloading.
  • the junction is offset by 90 degrees from an input position into the dumping zone 303 so that the haul truck 309 can be driven forwardly onto the turntable 305. turned 90 degrees (using the turntable) then dumping its load, and subsequently driven off the turntable 305 onto the second access way 333.
  • the haul truck 309 is only required to be rotated by a relatively small angle, in this instance 90 degrees, for unloading, thus reducing the cycle time of the unloading operation.
  • any dumping zone 303 in having two turntable units 1 associated therewith, presents two options for unloading of a haul truck 30; if one unit 1 is already in use, it may use the other unit 1 should. it be available. Furthermore, if one of the turntable units 1 is unavailable due to breakdown or maintenance, the dumping zone 303 can still be utilised via the other unit 1 .
  • the first and second access ways may be, for example, a sealed or unsealed road or a dirt track:
  • the vehicle is a haul truck and unloading the vehicle includes dumping of material carried by the haul truck.
  • the turntable unit is rotated through an angle of approximately 180 degrees so that the dump truck can be driven from the turntable unit along a path which was used to drive the truck onto the turntable unit.
  • the turntable unit is turned through an angle of approximately 90 degrees so that the dump truck can be driven from the turntable unit along a different path from that which was used to drive the truck onto the turntable unit.
  • the turntable may be operated to turn the truck after the step of dumping material from the truck.
  • the truck may approach the dumping zone along an access way which is adjacent the dumping zone.
  • the turntable may be rotated 90 degrees and the material in the haul truck dumped, and then the turntable rotated a further 90 degrees so that the haul truck may leave the turntable along the access way it travelled to access the turntable.
  • Vehicle unloading facilities 201. 301 can bring about a reduction in queuing and turning times, thus leading to operational and productivity gains, and improvements in safety.

Abstract

La présente invention concerne un module à plaque tournante qui se présente sous la forme d'une cartouche, qui peut être installé sur, dans ou au-dessus d'un terrain ou d'une surface découverts. L'invention porte aussi sur une installation de déchargement de véhicule, qui comprend : une zone conçue pour recevoir une charge transportée par un véhicule qui peut être déchargée à l'arrière du véhicule; une unité plaque tournante adjacente à la zone; et un chemin d'accès par lequel le véhicule peut être entraîné vers l'avant en direction d'une plaque tournante de l'unité. Une jonction entre le chemin d'accès et l'unité présente un décalage angulaire, sur l'axe de rotation de la plaque tournante, par rapport à la zone. Quant à la plaque tournante, elle peut tourner avec le véhicule disposé sur celle-ci afin d'amener l'arrière du véhicule au niveau de la zone de déchargement. L'invention a également trait à un procédé correspondant permettant de décharger un véhicule.
