The traversing trolley device 19 is provided with a gripping device 20 that grips the ore lifting pipe P.

Elevators 17, traveling devices 18, and traversing trolley devices 19 are provided in two sets each to increase pipe transfer efficiency, and a traversing trolley device 19 is provided above the lifting device 14 so as to be able to traverse toward the center of the hull 3 in the width direction. A transverse rail 32 is provided, and the transverse rail 32
In order to transfer the ore lifting pipe P in the longitudinal direction of the hull 3, a belt conveyor-type transfer conveyor 21 is provided as a storage section side transfer path.

Reference numeral 22 denotes an ore lifting pipe loading/unloading device disposed between the derrick 8 and the lifting device 14. The ore lifting pipe loading/unloading device 22 includes a bridge 23, and the bridge 23 is supported by bearing devices 24 and 25 consisting of pins and spherical bearings provided on the elevator guide rail 15 side and the derrick 8 side of the lifting device 14. At the portions 24 and 25, the bridge 23 can swing in the width direction of the hull 3, and can also swing somewhat in the longitudinal direction of the hull 3.
Further, a fixing device 26 such as a fluid pressure cylinder is disposed on the elevating device 14 side of the bridge 23 and has one end connected to the elevating device 14 side and the other end connected to the bridge 23.

In this case, the fixing device 26 on the lifting device 14 side is activated, the bridge 23 is fixed to the lifting device 14 side by the fixing device 26, and the fixing device 26 on the derrick 8 side at the other end is released, and the bearing device 25 so that the bridge 23 can swing freely relative to the derrick 8,
On the other hand, since it is integrated with the hull 3, the transfer conveyor 2
1 to the transfer conveyor 31 on the bridge 23 side can be smoothly delivered without relative movement between the transfer conveyors 21 and 31 even when the ship is rocking. When the ore lifting pipe P is completely transferred onto the transfer conveyor 31 on the bridge 23 side, the fixing device 26 on the lifting device 14 side is released, and it is made swingable by the bearing device 24, and at the same time, A fixing device 27 fixes the bridge 23 to the derrick 8. In this case, the bridge 23 is completely separated from the lifting device 14, is completely fixed to the derrick 8, and moves in the same manner as the derrick 8. In this state, the tilting cylinder 30 is operated to tilt the arm 28 on the bridge 23 side toward the derrick 8 together with the transfer conveyor 31, keeping the arm 28 and the transfer conveyor 31 vertical, and in that state, lift the arm 28 on the transfer conveyor 31.

When the pipe string 4 shown in FIG. 12 is lifted and the ore pipe P is removed and stored, the procedure may be reversed to that described above.

However, the above-mentioned device has the following problems.

() Ore lifting pipe loading/unloading device 22, lifting device 14,
Since the ore lifting pipe storage devices 10 are arranged in the longitudinal direction of the hull 3, a large space is required on the upper deck of the hull 3, and this element occupies a large amount of weight when chartering a ship.

() Since the ore lifting pipe storage device 10 is provided in two sections in the longitudinal direction of the hull 3, the transfer distance of the ore lifting pipe P is long, and therefore, due to the cycle time when transferring the ore lifting pipe P, the elevator 17, traveling device 18, and traversing trolley device 19 are required.

() () () As a result, the hull 3 and the pipe storage and transfer device 2 become larger, and at the same time, the cost increases and the economical efficiency deteriorates.

() If the ore lifting pipe P is supported at three points at both ends and the center, the ore lifting pipe P is always supported at two points by one transfer conveyor, so the transfer conveyor 2
The transition from 1 to 31 is smooth, but some of the various pipes are supported at two points,
In the belt conveyor system, the end of the tube falls between the transfer conveyors 21 and 31 at the transition point, making transfer impossible.

Therefore, in order to solve the problems of the above-mentioned apparatus, the present inventors proposed a tube storage and transfer apparatus as shown in FIGS. 7 and 8.

In Figures 7 and 8, the ore lifting pipe storage device 4
Reference numeral 1 denotes one section in the longitudinal direction of the hull 3, and a support member extending in the longitudinal direction of the hull 3 is provided inside the column of a gate-shaped frame 42 that is erected at a required interval in the width direction of the hull 3. A large number of rack supports 43 are provided vertically protruding at required intervals, and a rack support 44 that extends in the width direction of the hull 3 and also serves as a trolley rail is fixed to the tip of the support member 43. A rack for horizontal storage with the axis of the pipe P directed in the longitudinal direction of the hull 3 is fixed along the rack support base 44.

The ore lifting pipe storage device 41 is divided into two sections, one on the left and one on the right, in the width direction of the hull 3, and a space is provided in the center of the width of the hull 3 for an elevator 49, which will be described later, to rise and fall.

6 are arranged.

The traveling truck 46 is equipped with two lifting winches 4 at the front and rear.
7 is disposed, and an elevator 49 is suspended from a wire rope 48 which is wound up and let out by an elevating winch 47 as an elevating device capable of elevating and lowering the space in the widthwise center of the hull 3 of the ore lifting pipe storage device 41. A traversing trolley device 50 that can traverse the elevator 49 and the trolley rail portion of the rack support base 44 is disposed on the elevator 49 so as to be transferable.

An ore lifting pipe loading/unloading device 51 is provided inside the crane girder 45 near the derrick 8. That is, struts 52 and 53 are erected on the struts of the frame 42 on the side of the ore lifting pipe storage device 41 and the inner frame 8a of the derrick 8, and are supported so as to be rotatable in the longitudinal direction and the width direction of the hull 3. A bridge 54 is mounted on the columns 52 and 53 and has an arm 55 mounted thereon, which is pivoted on the same axis as the upper end of the column 53 and can be rotated up and down by a tilting cylinder 58. Fixing devices 56, 57 such as hydraulic cylinders, which are pivotally supported on the pillars or the inner frame 8a of the derrick 8, are connected to the pillars 52, 53, and the ore lifting pipe P
from the traversing trolley device 50 to the lifting pipe loading/unloading device 51
When transferring to the bridge 54, the fixing device 56
is fixed to the frame 42, and the lifting pipe P is attached to the arm 55.
The bridge 54 can be fixed to the derrick 8 when transferring from the derrick 8 to the derrick 8.

In the above device, the traveling truck 46 is stopped above the lifting ore pipe storage device 41, and the lifting winch 47 is started to raise and lower the elevator 49 holding the traversing trolley device 50 to the desired destination floor. When reaching the floor, the traversing trolley device 50
traverses the rail section of the rack support base 44 to the destination address of the destination floor by the traverse drive device, and stops at the destination address. Next, in the traversing trolley device 50, a gripping device (not shown) is lowered and opened, and the lifted ore pipe P is gripped by the gripping device.

When the gripping device of the traversing trolley device 50 grips the ore lifting pipe P, the gripping device ascends and lifts the ore lifting tube P from the rack, and the traversing trolley device 50 runs in the opposite direction and transfers to the center of the elevator 49, where it is attached to the elevating winch. 47, the elevator 49 is raised to the upper limit, and thereby the traversing trolley device 50 and the ore lifting pipe P are also raised to the upper limit position, and the elevator 49 is raised to the upper limit.
The traversing trolley device 50 is mounted on the traveling trolley 46.

When the traversing trolley device 50 holding the lifted ore pipe P is mounted on the traveling truck 46, a traveling drive device (not shown) is driven, and the traveling truck 46 moves toward the clean girder 4.
5 runs towards the derrick 8 side and stops on the arm 55 of the ore lifting pipe loading/unloading device 51.

Therefore, when the traveling truck 46 stops on the arm 55, the arm 55 is fixed to the frame 42 side by the fixing device 56, and the fixing device 57 is released so that the ore lifting pipe loading/unloading device 51 moves integrally with the hull 3. By lowering and opening the gripping device of the traversing trolley device 50 and opening and closing the gripping device (not shown) of the arm 55, the ore lifting pipe P is moved to the arm 5.
Hand it over to 5.

Once the ore lifting pipe P has been transferred onto the arm 55, the fixing device 56 is released and the arm 55 is fixed to the derrick 8 side by the fixing device 57 so that the ore lifting pipe transport device 51 does not rock even if the hull 3 rocks.The arm 55 is raised vertically upward by the tilting cylinder 58, so that the ore lifting pipe P is positioned vertically in the derrick 8, and the ore lifting pipe P is transferred to a holding device (not shown) inside the derrick 8.

By doing so, the installation area of the upper deck of the hull 3 is reduced, cost can be reduced, and even if the ore lifting pipe P is supported at two points, it can be smoothly transferred.

The device or the tube end gripping device and the intermediate gripping device are lowered, and if the tube is not a flexible tube, the tube end is gripped by the tube end gripping device, and if the tube is a flexible tube, the tube end gripping device and the intermediate gripping device are lowered. This grips the tube end and the intermediate flexible section.

[Example] Hereinafter, an example of the present invention will be described based on the accompanying drawings.

Figures 1 to 6 show an embodiment of the present invention, in which a trolley girder 59 extending in the longitudinal direction of the hull of a traversing trolley device 50 is fitted on both sides in the longitudinal direction of a rack supporting base 44 which also serves as a trolley rail, and rolls. The trolley girder 59 is equipped with a double-shaft traversing electric motor 61 with a brake, and two left and right speed reducers 62 connected to both shafts of the electric motor 61 are connected to the wheel 60.
