摘要： PURPOSE: To provide a method of easily and quickly grasping the shape of a hold required for the automatic operation of a continuous unloader at initial manual operation. CONSTITUTION: When the load of goods is carried by the manual operation of a continuous unloader, the tip position of a dig-out part 11 from a base point on a quay is computed from the position of a travel frame 2, the swivel angle and the elevation angle of a boom 4, the swivel angle of a bucket elevator 5, the expansion quantity of a dig-out part 11 and the like and the tip position of the dig-out part 11 is corrected from the relative position of a ship S with respect to the continuous unloader. The closest position of the tip position of the dig-out part 11 to the wall of a hold 20 within a divided zone at the time of diging operation of one layer is adopted as the maximum reach position to seek a plane shape in the hold by connecting the maximum reach position in the lateral direction at the time of diging operation of every layer. It is repeated at every time of cutting-in and the maximum reach position of a vertically continuous zone is connected in the direction of a depth to seek a profile shape inside the hold. The three-dimensional shape inside the hold is computed from both shapes.

摘要： PURPOSE:To supply grease, or supply lubricant to lubrication surfaces in a short time by communicating each greasing hole to communicate with an outer ink, a pin, a bush, and an inner link in order, and forming a single greasing port to be communicated with each greasing hole. CONSTITUTION:A roller chain 50 comprises a pair of outer links 52 disposed in a lot longitudinally at a specified interval, and both side parts of these are connected by a pair of pins 54 respectively. The pin 54 and a bush 56 are freely slidably engaged with each other at a boundary surface 58. The bush 56 and a pair of inner links 62 are engaged. In this case, greasing holes 52a, 54a are formed in the outer link 52 and the pin 54 respectively to be communicated with each other, and greasing hole 56a, 62a are formed in the bush 56 and the inner link 62 respectively to be communicated with each other as well. Grooves are formed in the pins 54 to be communicated with the greasing holes 54a, 56a, and a greasing port 66 is formed. Grease can thus be supplied to a number of the boundary surfaces by only supplying grease to the single greasing port 66.

摘要： PURPOSE:To dispense with an iron shell reinforcement at the connect part in the base part of a connecting tube by specifying the ratio of the tube diameter of the connecting tube to the dome diameter of a regenerator and the ratio of the tube diameter of the connecting tube to the dome diameter of a combustion chamber, respectively. CONSTITUTION:The side wall of the dome 10 in the regenerator 1 and the side wall of the dome 11 in the combustion chamber 2 are directly connected with the connecting tube 4 without using a flexible joint to form an outer combustion type hot stove 12. In this hot stove 12, the ratio RD/TD of the tube diameter RD of the connecting tube 4 to the diameter TD of the regenerator 1 is specified to 0.24-0.60. Further, the ratio RD/ND of the tube diameter RD of the connecting tube 4 to the dome diameter ND of the combustion chamber 2 is specified to 0.44-0.60. By this method, the locally generated stresses at the base parts A, B of the connecting tube are suppressed and the iron shell reinforcements in the base parts A, B of the connecting tube are made unnecessary.

摘要： PURPOSE:To tie an annealing wire assuredly by a method wherein when the other annealing wire is pulled out to one annealing wire side, cotton on the other annealing wire side is prevented from being compressed. CONSTITUTION:A desired quantity of cotton is compressed, and a corrugated fiberboard box 9 is fitted in, and after the corrugated fiberboard box 9 is held by a piston 3, a needle 10 is advanced, and the head part is projected to the outside of a side wall (1c) on the opposite side. At this time, a guide roller control device 25 raises a cylinder device 18 to raise a protruding plate 20, and a guide roller 21 is insert between the other annealing wire 16 and the side wall (1c). When the needle 10 is made to retreat, a hook part 11 at the heat part catches the other annealing wire 16, and the other annealing wire 16 is pulled to one annealing wire 15 side. At this time, a compressed cotton 30 side of the other annealing wire 16 is pulled by the guide roller 21, and is not pressed to the compressed cotton 30. When the needle 10 retreats further, and the first annealing wire 15 is also caught by the hook part 11, and the needle 10 returns to the original location. As soon as both annealing wires 15, 16 are twisted by a twister 28, the annealing wires 15, 16 are cut by operating a cutter. At this time, a control means 25 lowers the cylinder device 18 and releases the other annealing wire 16.

摘要： PURPOSE:To efficiently collect dust generated at the time of tapping molten iron by arranging a shield plate for closing space part in an iron tapping working floor to a trough cover for preventing splash in the front of an iron tapping hole in a blast furnace. CONSTITUTION:At the time of flowing the molten steel in the furnace into an iron tapping trough 3 by boring the iron tapping hole 2 in the blast furnace 1 with a boring machine 4 or plugging the tapping hole 2 with a mud gun 5, the dust generated from the iron tapping hole is collected by a cover 8 and a trough cover 9 for preventing the splash on the iron tapping trough 3. At the time of boring and plugging the iron tapping hole 2, as the cover 8 for preventing the splash becomes an obstacle, the cover is evacuated by a hanging device 13, and after opening the hole or executing the plugging work, the boring machine 4 or the mud gun 5 is evacuated from the front of the iron tapping hole 2 to return back the cover 8 on the iron tapping trough 3. In this case, by arranging a side surface shield wall 16 provided with sucking ducts 10, 11 at the front part of the iron tapping hole 2, a large quantity of the dust generated at the time of tapping the molten iron, is sucked through the suction ducts 10, 11 and the dust while the cover 8 for preventing the splash evacuates, is collected in excellent dust collecting efficiency.
