摘要： PURPOSE:To surely guide a bucket chain according to the circulating conditions of a bucket. CONSTITUTION:A selectable and movable guide rail 15 is provided at positions where a roller locus line 8a of a bucket chain passing a guide sprocket 8 on the top end side of a horizontal frame 4 is continued and not continued to a horizontal guide rail 12c. Then the movable guide rail 15 is moved selectively to surely guide a roller to the horizontal guide rail 12c and prevent entry into the horizontal guide rail 12c. Thus the bucket chain is guided surely according to the circulating conditions of a bucket.

摘要： PURPOSE:To safely perform automatic operation in a high degree, improve efficiency, and save labor in cargo handling work by excavating and unloading the cargo while grasping the cargo shape and the relationship between an unloader and the ship during cargo handling, and controlling the operation of an excavation section. CONSTITUTION:Three dimensional cargo shape before excavation is always grasped in parallel with operation of excavation, for example, in the case where the shape of top cargo is conical, operation pattern to make the top flat is required, and parameters for allowing turn operation for excavation from the to of the conical cargo, that is, the excavation orbit and excavation speed of an unloader 5 are calculated, and an excavation position obtained by correcting the variation quantity of a ship 2 is determined. The variation quantity of each drive system of the unloader 5 from this position is determined to perform excavation operation for making cargo flat. In the next step, for a flat cargo. hierarchy operation pattern is applied to perform excavation based on the excavation position corrected with the variation quantity of the ship. In addition, when caked grain position is detected during the excavation of bottom cargo, a raking device is actuated by a raking operation pattern to rake off the cargo stuck to the side wall.

CONSTITUTION:The rod 17b of a swing cylinder 17 is extended, and the rod 20b of a turning cylinder 20 is contracted, and a swing frame 16 and an excavating frame 19 are kept in an L-shape. In this state, the bulk cargo 27 at the center part is discharged by vertically introducing the excavating device into a hold 28, in this state. While, the rod 17b is contracted, and the rod 20b is extended, and the swing frame 16 is swung forwardly, keeping the excavating frame 19 horizontally. At the same time, the cylinder 17 is driven to keep the tension of a bucket chain elevator 25 constant. In this state, the bulk cargo 27 in the peripheral part in the hold 28 is discharged. Then, the load of the excavating frame 19 is detected by a sensor 30, and the rod 20b is contracted in case of overload.

摘要： PURPOSE:To detect a damage of a bearing or the like at the early time and improve the operation efficiency by providing a control means for controlling the operation of a failure of stub roller alarm device and the operation of a belt conveyor on the basis of the amplitude by vibration of a stub roller. CONSTITUTION:A distance measuring sensor 26 measures a distance from a stub roller 21, and outputs a result of this measurement to a computing means 27. The computing means 27 computes the amplitude by vibration of the stub roller 21 on the basis of the detecting signal from this distance measuring sensor 26, and output a result of this computing to a control device 28. The control device 28 performs the control on the basis of a largeness of the amplitude by vibration of the stub roller 21 output from this computing means 27, and in the case where this amplitude by vibration of the stub roller is smaller than a preset value, the control device 28 continues the operation of a belt conveyor type continuous unloader, and in the case where this amplitude by vibration is larger than the preset value, the control device 28 operates a failure of stub roller alarm device 30, and furthermore, stops the operation of the belt conveyor.

The distances L1, L2 from a detecting part of the measuring instrument to the point of measurement on the bulk cargo and the angle of oscillation are measured for each reference coordinate, the results are transmitted to a connecting device, and the coordinates of the points of measurement above the bulk cargo are obtained based on the distances L1, L2 and the angle of oscillation. The coordinate gpDELTA2 of the height of the bulk cargo surface above the respective reference coordinates is obtained from two coordinates of the points of measurement on the bulk cargo adjacent to the reference coordinates, and the upper surface of the bulk cargo 20 is measured as the net-shaped three dimensional data to grasp the residual amount of the bulk cargo.

摘要： PURPOSE:To improve the efficiency in the discharging operation by installing a protecting plate having a load breaking mechanism at the top edge of a bucket chain elevator excavating device and reducing the resistance at the top edge due to the excessive load such as the fall of the bulk cargo. CONSTITUTION:A bucket chain elevator 12 which carries out the scraping for the bulk cargo by an L shaped top edge part bucket 13 at the lower edge part of the elevator 12 is equipped with a load breaking mechanism which is supported on the L shaped part elevator and serves as a top edge bucket protecting plate 24 or a wheel type load breaking mechanism, at the side part or in front of the top edge bucket 13. The load applied to the top edge of an excavating part because of the suspension of operation and the breakage of the equipment due to the excessive load applied from the bulk cargo such as the falling of the bulk cargo is reduced to reduce the resistance in operation, and the efficiency in the discharging operation is increased.
