Abstract
An apparatus for automatically and continuously withdrawing coal from a ship's bunker by means of a screw conveyor suspended from a gantry beam transversely of the bunker in order to convey the coal towards one or both sides. The gantry beam travels on supporting beams extending in the longitudinal direction of the bunker and being movable in their turn on vertical beams by means of hydraulic devices mounted each at one end of the supporting beam and engaging the associated vertical beam. By being arranged in this manner, the screw conveyor covers the entire bunker area and can also be operated while the ship is under way at sea.
Claims6
Apparatus for continuously withdrawing coal from a ship's bunker, also when the ship under way at sea, comprising in combination
- at least two pairs of vertical beams fixedly connected to the ship's hull, the beams of each pair being spaced apart longitudinally of the ship;
- hydraulic means on each of said vertical beams, said hydraulic means being synchronized and adapted, upon supply of pressure medium, to climb up or down on said beams;
- supporting beam means extending horizontally and longitudinally of the ship and supported by said hydraulic means of each pair of vertical beams mounted longitudinally of the ship, said supporting beam means being provided each with a runway;
- a gantry beam extending horizontally and transversely of the ship and having wheeled carriages fixedly spaced apart longitudinally of said gantry beam, the wheels of said carriages rolling on the runways of said supporting beam means;
- means for driving the wheels on each carriage for moving said gantry beam longitudinally along said supporting beam means;
- conveyor screw means suspended from said gantry beam and extending transversely;
- driving means for said conveyor screw means for so rotating the latter that it conveys coal at least towards one long side of the ship;
- and
- a discharge hopper along at least one of the long sides of the ship for taking up coal conveyed towards said side by said conveyor screw means.
