摘要： PURPOSE: To provide an operation control method and an operation control device for a bucket elevator excavating device capable of automatically and efficiently excavating a heap of a bulk cargo generated by a collapse. CONSTITUTION: Multiple sensors 15 detecting the distance to a bulk cargo 14 are arranged on the excavating frame 5 of a bucket elevator excavating device, the height H of the start end section of a heap 14b of a bulk cargo generated by a collapse is calculated from the detected values of the sensors 15, and 1/2 of the calculated height H is used for the erection quantity of the excavating frame 5 for the forward excavating operation. The height (h) of the end section of the heap 14b of the bulk cargo is calculated from the detected values of the sensors 15, and the calculated height (h) is used as the erection quantity of the excavating frame 5 for the return excavating operation.

摘要： PURPOSE: To provide an excavating device for a bucket elevator capable of grasping individual loads such as the bucket chain tension and excavating force and surely performing the fixed-quantity delivery control. CONSTITUTION: Oil pressure sensors 22, 23, 24 are provided at various sections, and a controller 25 compares the excavating force calculated from the detected value of the oil pressure sensor 23 (excavating force equivalent pressure + chain tension equivalent pressure) and the detected value of the oil pressure sensor 24 (chain tension equivalent pressure) with the excavating force target value and controls the lateral excavating speed of an excavating device to obtain the prescribed speed target value. The excavating force target value is updated in sequence based on the compared result between the lifting force calculated from the calculated excavating force and the detected value of the oil pressure sensor 22 (lifting force equivalent pressure excavating force equivalent pressure) and the lifting force target value, the lifting force is made coincident with the target value, the delivery quantity of the bulk cargo is made constant, and the fixedquantity delivery control can be surely performed.

摘要： PURPOSE:To simplify an unloader in structure as well as to aim at reduction in weight and operability, by installing a bucket-wheeled vertical rocking frame in a lower end of a vertical conveyor, and constituting a hopper so as to keep its verticality at all times, in case of the unloader for a bulk cargo inside a ship. CONSTITUTION:A bucket wheel type cargo collection receiver 20 is operated by a vertical conveyor frame 1, while a swing frame 22 is swung up and down by a swing driving device 24. And, a pair of bucket wheels 27 at a tip end of the swing frame 22 is rotated by a driving device 28, scraping a cargo in bulk, and it is fed to a hopper 30. At this time, even if the swing frame 22 is swung up and down, the hopper 30 always keeps its verticality owing to each action of link mechanisms 35a and 35b. In addition, a conveyor 21 with a machine is set up there, whereby the cargo in bulk is prevented from scattering. With this constitution, reduction in weight and improvement in operatability are well promoted.

摘要： PROBLEM TO BE SOLVED: To clean all buckets uniformly without consuming a great amount of water in a short time by installing nozzles for spouting water toward the bucket of a bucket line and also equipping a cleaning water supply system for supplying the water to the nozzle. SOLUTION: At the cleaning time of a bucket line 30, during the pause of an unloader or the pausing time of a pier loading unloading, the bucket 32 supplies a cleaning water from a cleaning water supply system 7 to a first nozzle pipe 5 and a second nozzle pipe 6 while circulation running the bucket line 30 slowly in an empty state and the water is discharged from the nozzles to the outer surface of the bucket 32 and a soil and dust adhered to the outer surface are washed out. As the water spouted from plural nozzles installed on the nozzle pipe 5 or 6 arranged on a U shape is discharged from all sides to the outer surface of the bucket 32 and at two places of the upper first nozzle pipe 5 and the lower second nozzle pipe 6, respective buckets 32 can be cleaned surely in a circulating order.

摘要： PURPOSE:To provide a bucket excavator for an unloader by which the occurrence of excessive excavating reaction of a bucket can be prevented and a load applied to a bucket chain line can be maintained within a certain range. CONSTITUTION:When a detecting value (excavating reaction P1 of a bucket 9) of a pressure detector 18 exceeds a preset value, a shock absorbing hydraulic cylinder 15 is contractively driven by a bucket excavating reaction control part 19, and a rear guide sprocket 16 is upward moved, and a biting-in quantity of the bucket 9 is reduced, and the excavating reaction P1 of the bucket 9 is reduced. The excavating reaction P1 of the bucket 9 and a load applied to a bucket chain line 8 are accurately found according to the detecting value of the pressure detector 18 and a detecting value of a bucket load detector 10 by a bucket load control part 20 or the like, and traversing speed of an excavating part, a biting-in quantity of the bucket 9 or moving speed of the bucket 9 are controlled according to these, and the excavating reaction P1 of the bucket 9 and the load applied to the bucket chain line 8 are controlled.

摘要： PURPOSE:To reduce wearing, vibration, noise, etc., to improve durability and further to miniaturize an intermediate guide [art of a chain link and the column end part, in a device. CONSTITUTION:Since each guide roller of guide roller train of small diameter, set up along circular arc-shaped moving path (guide roller support) 8 to 11 of fixed radius of curvature, is brought into contact with one side of a bucket chain link, to change a direction of a chain 1 by rolling contact of each guide roller, an impact generated at the time of meshing relating to a sprocket is eliminated, to prevent generating vibration and noise. Since each guide roller in a guide roller train of small diameter is smoothly rotated, also wearing due to slipping between each guide roller and the chain link is eliminated, to resist against use for a long period. The guide supports 8 to 11 are small in size, and when used in an intermediate guide part and column lower part of the bucket chain 1, miniaturization thereof is performed.
