| 摘要 | A trough chain conveyor for unloading, from the top, vessels such as ships, barges and the like is pivotally supported on a crane with means for arranging the conveyor at a plurality of angles to the vertical. The material is conveyed upwardly through troughs to the upper end of the conveyor and then is unloaded into a discharge container supported on the conveyor. Another conveyor is located on the crane for receiving the unloaded material and completing the unloading operation. The trough chain conveyor contains a pair of laterally spaced endless chain strands reversibly movable through troughs for unloading the material. | ||||||
| 权利要求 | 1. A discharge device for unloading a ship, barge, or similar vessel through an opening in its upper surface, comprising a lifting crane, an elongated trough chain conveyor articulated to said lifting crane for placement in an upwardly directed position and for movement about a horizontal axis so that said conveyor is positionable at an angle to the vertical on both sides of a vertical plane through the horizontal axis, said trough chain conveyor comprising a first chain trough and a second chain trough and an endless chain strand extending through said first and second chain trough and having means thereon for lifting material in the upward direction through one of said troughs, means for driving said chain strand in a reversible manner so that the material can be lifted through either of said first and second troughs while the other acts as a return trough for said chain strand; said trough chain conveyor comprising a pair of laterally spaced chain strands, and a discharge container located at the upper end of said conveyor between said chain strands for receiving material conveyed upwardly by said chain strands. 2. A discharge device, as set forth in claim 1, wherein said discharge container is arranged to receive material flowing inwardly thereto from said chain strand located in the upper of said first and second troughs when said trough chain conveyor is positioned at an angle to the vertical, and a pendulum flap pivotally mounted at its upper end within said discharge container for blocking the passage of the material being lifted into the return trough from the one of said first and second troughs acting as the material lift trough. 3. A discharge device, as set forth in claim 2, wherein said trough chain conveyor comprises a pair of laterally spaced chain strands, said discharge container extending laterally outwardly from each of said first and second troughs through which each of said chain strands are driven, said discharge container extending transversely between said chain strands and forming therebetween a common downwardly extending passage, a drop pipe connected to and extending downwardly from the lower end of said discharge container, and a conveyor mounted on said lift crane and positioned below said drop pipe for conveying material from said trough chain conveyor. 4. A discharge container, as set forth in claim 3, wherein said trough chain conveyor comprises a plurality of struts extending laterally between said first and second troughs containIng said pair of chain strands. 5. A discharge device for unloading a ship, barge, or similar vessel through an opening in its upper surface, comprising a lifting crane, an elongated trough chain conveyor articulated to said lifting crane for placement in an upwardly directed position and for movement about a horizontal axis so that said conveyor is positionable at an angle to the vertical on both sides of a vertical plane through the horizontal axis, said trough chain conveyor comprising a first chain trough and a second chain trough and an endless chain strand extending through said first and second chain trough and having means thereon for lifting material in the upward direction through one of said troughs, means for driving said chain strand in a reversible manner so that the material can be lifted through either of said first and second troughs while the other acts as a return trough for said chain strand; and a discharge container located at the upper end of said trough chain conveyor above the location at which said conveyor is articulated to said lifting crane, said discharge container extending outwardly from the outer surfaces of said troughs so that said material being lifted can be discharged in an outward and a downward direction thereto from said chain strand when said trough chain conveyor is positioned angularly to the vertical and, in the angular position, the lower portion of said chain strand is utilized for lifting the material to said discharge container. 6. A discharge device, as set forth in claim 5, wherein said lifting crane comprises a movable tower, a jib mounted on said tower for pivotal movement about a horizontal axis, means for displacing said jib through a vertical plane about said horizontal axis, said trough chain conveyor being articulated to said jib on the opposite side of said horizontal axis of said jib from said means for displacing said jib through a vertical plane, means secured to said jib and to said trough chain conveyor for pivoting said trough chain conveyor about its point of articulation to said jib, and a drop pipe mounted in said tower spaced from said trough chain conveyor, said conveyor on said lift crane and located on said jib and arranged to transfer material from said trough chain conveyor to said drop pipe in said tower. |
