Definitions

  • MATERIAL HANDLING APPARATUS This invention relates to material handling equipment and arose from a consideration of what is involved in unloading a large vessel containing bulk material such as ore, coal and other minerals.
  • material handling equipment including a boom conveyor means by which material may be moved along the boom, an elevator unit carried by the boom so as to be rotatable relatively to the boom about an axis extending transversely of the conveyor, the elevator unit including an elevator and means for effecting loading of the elevator at a location displaced along the elevator unit from the conveyor from a location laterally of the axis, and means whereby for any orientation within a range of the elevator unit relative to the boom material discharging from the elevator passes to the conveyor.
  • a luffing boom extends laterally of the frame 1 and is mounted on the platform 4 to pivot about a horizontal axis that intersects the vertical axis of the slewing ring 4a.
  • the luffing boom 10 is provided with a counterbalance 11 and wire ropes 12 and 13 connect the outer ends of the counterbalance 11 and the luffing boom 10 to a post 14.
  • the vertical angle of the luffing boom is controlled through the pulley arrangement 15 that is controlled by the motor 16.
  • the boom 10 is in two parts, 10a and 10b connected together by a horizontal pivot at 10c.
  • the part 10b is horizontal and by means of the parallel linkage 28, it will remain horizontal during variations of the inclination of the boom 10 to the horizontal.
  • An elevator unit 30 hangs from the outer end of the part 10b of the boom 10 into the hold of a ship, through the hatch 29.
  • the unit includes a rigid spine 30a carrying an endless bucket conveyor 30b, the upper end of the spine having a superstructure 31 into which the buckets of the conveyor empty.
  • a coupling indicated generally by 33, by which the elevator unit 30 hangs is connected between the part 10b and the bracket arm 32.
  • the coupling 33 includes a part 33a that is connected to the part 10b of the boom 10 by swivel means 33 that allows the parts to rotate relatively to each other about a vertical axis that passes through the conveyor 17, but prevents other relative movement.
  • the part 33a is pivotally connected to the bracket arm 32, the pivot axis intersecting the axis of the swivel means 330 so that gravity maintains the orientation of the elevator unit constant.
  • the inlet to this chute 35 is so disposed as to receive material brought into the superstructure 31 by the bucket conveyor 30b and the arrangement is therefore such that material from the bucket conveyor 30b will fall on the conveyor 17 throughout a range of rotation of the elevator unit 30 relatively to the boom 10.
  • a support 40 extends in the opposite direction to the bracket arm 32.
  • Twin bucket wheels 41 are arranged for rotation about a horizontal axis on the outer end of the support and a gathering feeder conveyor 42 extends at a slight upward incline from this to the elevator 30b.
  • the bucket conveyor 30b is fed by the bucket wheels 41 from a location laterally of it and this facilitates the emptying of bulk ore carriers easily and with high reclaim rates.
  • the hatch 29 that gives access to the hold is of smaller cross-section than the hold, but the bucket wheel reaches under the overhanging part 50 of the deck structure. Since both the boom 10 and the elevator unit 30 may be slewed, there is considerable freedom of movement of the bucket wheels 41 within the hold so that the chance of a thick lining of material being beyond the reach of the unloader is small. Moreover since the boom 10 can be slewed it can be parked along the jetty when not in use to permit free access of ships to the jetty.
  • Apparatus as claimed in claim 4 in which the axis about which the boom is luffable intersects the axis about which the platform is rotatable.
