MOVABLE UNLOADING CONVEYOR FOR UNLOADING SAND PUT ON A SHIP INTO A STACK SPOT AT ONE TIME REGARDLESS OF LONGITUDINAL AND HORIZONTAL SWINGS OF THE SHIP

摘要

PURPOSE: A movable unloading conveyor is provided to prevent the sand from sweeping away by transporting and unloading the sand directly to a stack spot adjacent to a ship and to change quickly the position of the conveyor even if the ship rolls back and forth by waves. CONSTITUTION: A movable unloading conveyor is composed of a carrying unit(3) extended axially and installed with a sand conveyor belt(7) and a moving unit(5) for moving longitudinally and horizontally and supporting tiltably and controlling the carrying unit. The carrying unit comprises a truss body(9) extended axially; the conveyor belt installed on the truss body to orbit; and a hopper(11) disposed at the upper end of the belt to input the sand on the belt. The moving unit is composed of a moving unit body(15) having an operation room(13) with an operation control unit; a hydraulic extension support bar(17) for controlling a tilting motion of the carrying unit by the control unit and supporting the carrying unit; a moving wheel(19) of which forward and backward motions are controlled by the control unit; and a hydraulic extension support frame(21) for propping up the moving unit body for the ground(20) from the underside.
