(i) f! Since the ore pipe loading and unloading device 22, the lifting device 14, and the ore lifting pipe storage device 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 is required when chartering a ship. occupies a large weight.

■ Since the ore lifting pipe storage device IO is provided in two compartments in the longitudinal direction of the hull 3, the transfer distance of the ore lifting pipe P becomes long. Two systems of traveling equipment 218 and transverse Toro January 9 are required.

@(+)■ increases the size of the hull 3 and the pipe storage and transfer device 2, and at the same time increases the cost, which is not economical.
□ (f) If the ore lifting pipe P is supported at three points at both ends and the center,
Since the lifting pipe P is always supported at two points by one transfer conveyor, the transfer from transfer conveyor 21 to 31 is performed smoothly, but some of the intubations are supported at two points. , in the belt conveyor system, the transfer conveyor 21
At the transition part of and 31, the pipe end falls between them,
Transport becomes impossible.

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

In FIGS. 7 and 8, the ore lifting pipe storage device 41 is one section in the longitudinal direction of the hull 3, and is supported by gate-shaped frames 42 erected at required intervals in the width direction of the hull 3. 42
A support member 43 extending in the longitudinal direction of the hull 3 is provided inside part a.
A large number of rack supports 44 are fixed to the tip of the support member 43 and extend in the width direction of the hull 3 and also serve as trolley rails. A rack that is horizontally stored with the P axis directed in the longitudinal direction of the hull 3 is fixed along the rack support base 44.

The ore lifting pipe storage device 41 has two left and right sides in the width direction of the hull 3.
A space is provided at the center of the hull 3 in the width direction for raising and lowering an elevator 49, which will be described later.

When reaching , the traversing trolley 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 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 50 grips the lifted ore pipe P, the gripping device rises and lifts the ore pipe P from the rack, and the traversing trolley 50 runs in the opposite direction and transfers to the center of the elevator 49, where it is lifted by the lifting 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 and the traversing trolley 50 are mounted on the traveling carriage 46.

The lifted ore pipe P is vertically positioned in the derrick 8 by standing vertically, and the lifted ore pipe P is delivered to a gripping device (not shown) in the derrick 8.

By doing this, the installation area of the upper deck of the hull 3 is reduced, reducing costs, and a belt conveyor type is used to transfer the ore lifting pipes P from the ore lifting pipe storage device 41 to the lifting ore pipe loading/unloading device 51. Since there is no need to use a transfer device, it is possible to eliminate the problem of the tube end falling between the transfer devices.

A bridge supported on a strut that can rotate in the width direction of the hull, and a grip that is pivoted to the derrick side end of the bridge so that it can rotate up and down and grips the pipe delivered from the traveling truck and delivers it to the derrick. an arm with a device;
A fixing device is provided for selectively fixing the bridge to either a structure that swings integrally with the hull or a derrick.

[Function] When the pipe is transferred from the traveling truck to the arm of the pipe loading/unloading device, the bridge is fixed to the structure that moves along with the ship's hull, and the arm rotates upwards, causing the pipe to move onto the arm. The bridge is fixed to the derrick when it is transferred from the derrick to the derrick. Therefore, the pipe loading/unloading device is compensated for any oscillation during work, and can work safely.

[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

Figures 1 to 6 are Figure 7, which illustrates one embodiment of the present invention.
Support brackets 57 and 58 are fixed to the struts 42a 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 pins 59. A strut 85.68 that can swing in the longitudinal direction of the hull 3 is pivotally connected to a support bracket 6L82 that can swing in the width direction of the hull 3 via a pin 63.64 whose axis extends in the width direction of the hull 3. , strut 65.8
Bridge 52 is pivotally attached to the upper end of 8 via pins 67, 88 parallel to pins 63, 64, and a hydraulic cylinder type longitudinal fixing device 69.
70 is connected to the strut 85.8G as a sway compensating device so as to be able to restrict the movement of the bridge 52 in the longitudinal direction of the hull 3, and a width of a hydraulic cylinder pivoted on the strut 42a and the inner frame 8a. The direction fixing devices 71, 72 are connected to the struts 65, 68 as vibration compensating devices so as to restrict the movement of the bridge 52 in the width direction of the hull 3.

A pin 73 is attached to the end of the bridge 52 on the derrick 8 side so as to be coaxial with the pin 68, and an arm 53 that can be tilted in the longitudinal direction of the hull 3 is pivotally attached to the pin 73. The tip of a tilting cylinder 56 whose one end is pivotally supported is connected to the arm 53, two sets of gripping devices 75 which can be opened and closed by an opening/closing cylinder 74 are attached to the arm 53, and the arm 53 is attached to the arm 53 to position the ore lifting pipe P in the axial direction.

When the traversing trolley 50 holding the lifted ore pipe P is mounted on the traveling truck 46, the traveling truck 46 travels on the glen girder 45 toward the derrick B side and stops on the lifted ore pipe carrying-in/out device 51. At this time, even if the hull 3 is shaken by waves, the derrick 8 does not sway back and forth or side to side, and the ore lifting pipe storage device 4
A relative movement occurs between the 1 side and the derrick 8 side. Therefore, Bu1
If the Rusoji 52 is fixed to the derrick 8 side, the bridge 52 will not move even though the hull 3 will sway and the traveling trolley 46 and the traversing trolley 50 will also sway, so the ore lifting pipe P can be removed from the traversing trolley 50. It is difficult to lower the arm 53. Therefore, in this case, it is necessary to compensate for the oscillation of the bridge 52 of the ore lifting pipe loading/unloading device 51. That is, when the traveling trolley 46 reaches the arm 53 of the lifting ore pipe loading/unloading device 51, the front-back fixing device 69 and the width-wise fixing device 71

As a result, both the bridge 52 and the arm 53 experience the same sway as the ore-lifting pipe storage device 41 on the hull 3 side, and therefore, there is a relative sway between the traveling truck 4B and the ore-lifting pipe loading/unloading device 51. will disappear. Therefore, the traveling trolley 46
The elevator of the traversing trolley 50 carried by the trolley 50 is operated to lower the ore lifting pipe P onto the arm 53, and the axial position of the ore lifting pipe P is adjusted by the adjustment device 76, and the opening/closing cylinder 7

Furthermore, the traveling truck 46 is retreated onto the ore lifting pipe storage device 41.

On the other hand, the ore lifting pipe P suspended on the arm 53 is connected to the derrick 8.
It is delivered to the derrick 8 after waiting for the progress of the work.

This delivery is first carried out by moving the bridge 52, which is fixed to the ore lifting pipe storage device 41 and is swinging integrally with the hull 3, horizontally while closing the hydraulic valve of the width direction fixing device 72 on the derrick 8 side. The bridge 52 is fixed to the derrick 8 so that the center line in the width direction matches the center line of the derrick 8, and the hydraulic valves of the width direction fixing device 71 on the lifting pipe storage device 41 side and the longitudinal width direction fixing device B9 are fixed.

The angle α between the vertical line of the support column 66 and the axis of the bottle 60 is 9
The angle is adjusted to 0 degrees, and the hydraulic valve of the longitudinal direction fixing device 70 is closed.

As a result, the bridge 52 is fixed to the derrick 8 in a predetermined state, and the bridge 52 and the arm 53 move in the same manner as the derrick 8.

Next, a tilting cylinder 5 whose one end is connected to the bridge 52
6 is activated, the arm 53 is rotated upward around the bin 73, and the elevation and elevation of the arm 53 is stopped at a position where the axis of the ore lifting pipe P supported by the arm 53 becomes parallel to the vertical center line of the derrick 8. let

Although not shown, a racking arm is provided in the derrick 8, and this racking arm moves up and down and travels toward the arm 53 to approach the arm 53, and the gripping device 75 is released to remove ore from the arm 53. Receive pipe P. Lifting pipe P
