In this example, the pipe A is a long steel pipe having a large diameter.

Next, the operation will be described based on such a configuration.

(1) The pipe loading machine 1 is unloaded from the hatch by the crane B, and the rail 2 is placed on the floor surface G or the pipe A from the bottom of the hatch to the left. The loading body 3 is located under the hatch (see FIG. 4). (2) The three pipes A are lowered and placed on the load 3 by the crane B (see FIG. 5). (3) The load 3 is moved to the left with respect to the rail 2 by extending the reach cylinder 19 of the front-rear drive means 4 (see FIG. 6). (4) The joined body 5 is joined to the floor G or the pipes A by extending the lift cylinder 25 of the lifting / lowering drive means 6 to separate the rail 2 from the floor G or the pipes A (FIG. 7
reference). (5) The rail 2 is moved to the left with respect to the load 3 by shortening the reach cylinder 19 of the front-rear drive means 4 (see FIG. 8). (6) The joint body 5 is separated from the floor surface G or the pipes A by shortening the lift cylinder 25 of the lifting / lowering drive means 6 to join the rail 2 to the floor surface G or the pipes A (FIG. 9
reference). (7) The pipe stacking machine 1 is moved to a predetermined position by appropriately repeating the operations (3) to (6) (see FIG. 10). (8) When the pipe stacking machine 1 is moved to a predetermined position, the pipes A are moved from the loading body 3 by the sending means 8 while the pipe stacking machine 1 is retracted by the diameter of the pipes A. Roll down sequentially and stack on floor G or tubing A. (9) In other words, the tilting cylinder 31 of the sending means 8 is extended to tilt the tilting plate 30 forward, and
By lowering the delivery arm 33 by shortening 5, the foremost first tubing A is rolled forward and stacked at a predetermined position. At this time, the base end of the delivery arm 33 projects above the tilting plate 30 via the notch 36, so that the forward movement of the second and subsequent tubing A is prevented, and thus serves as a so-called stopper (see FIG. 11). (10) The tilting cylinder 31 of the feeding means 8 is shortened to return the tilting plate 30 to the horizontal position, and the tilting cylinder 35
To return the delivery arm 33 to the raised position (FIG. 12).
reference). (11) The load 3 is moved to the right with respect to the rail 2 by the diameter of the pipe A by the reach cylinder 19 of the front-rear drive means 4 (see FIG. 13). (12) The joined body 5 is joined to the floor G or the pipes A by the lift cylinder 25 of the lifting / lowering drive means 6 to separate the rail 2 from the floor G or the pipes A (see FIG. 14). (13) The rail 2 is moved rightward with respect to the load 3 by the reach cylinder 19 of the front-rear drive means 4 (FIG. 15).
reference). (14) The joined body 5 is separated from the floor surface G or the pipe A by the lift cylinder 25 of the lifting / lowering drive means 6, and the rail 2
On the floor G or the tubing A (see FIG. 16). (15) The second tubing A is rolled forward by extending the tilting cylinder 31 of the feeding means 8 to tilt the tilting plate 30 forward and shortening the elevating cylinder 35 to lower the feeding arm 33. To place in place. At this time, since the base end of the delivery arm 33 projects above the tilting plate 30 via the notch 36, the forward movement of the last third tubing A is prevented, and serves as a so-called stopper (see FIG. 17). ). (16) By performing the above operations (10) to (15), the third tubing A is rolled forward and stacked at a predetermined position. (17) When the loading on the left side of the ship is completed, the pipe palletizing machine 1 is turned and the right side of the ship is loaded, and the pipe palletizing machine 1 is lifted by the crane B to another place. Evacuate and place and directly load under the hatch using crane B, ending one-stage loading. Then, according to the same procedure, the subsequent and subsequent stowage is performed.

When the motor 28 of the turning drive means 7 is rotated to rotate the turning plate 22 of the joined body 5 with respect to the load 3 by the small gear 27 and the internal gear 26, the joined body 5 is turned. The direction of the load 3 and the rail 2 with respect to the plate 22 can be changed. Therefore, it is possible to finely adjust the directions of the load 3 and the rail 2 and to change the direction from the left to the right.

Four lifting cylinders 2 of the lifting drive means 7
5 are simultaneously extended and retracted by the same amount, the load 3 and the rail 2 can be moved up and down in parallel with respect to the joined body 5. And the rail 2 can be moved up and down by tilting forward and backward or right and left. Therefore, even if the ship is tilted, the loading body 3 can always be kept horizontal, and conversely, the loading body 3 can be positively tilted in a predetermined direction.

The elastic plates 11 and 23 are adhered to the lower surface of the channel member 9 of the rail 2 and the lower surface of the revolving plate 22 of the joined body 5, so that the elastic plates 11 and 23 They will not be damaged by joining.

Since the revolving plate 22 and the elastic plate 23 of the joined body 5 are formed in a flat plate shape, Japanese Utility Model Publication No. 5-8259 (Japanese Utility Model Application Laid-open No.
No. 110430), the stability is increased as compared with the pallet lifting jack described in US Pat. That is, since the pallet lifting jack is of a four-point support type, there is no problem when the joining surface is the floor surface G, but when the joining surface is on the pipe A, the jack is equal to the vertex pitch of the adjacent pipe A. If the pitches of the jacks do not match, not all jacks can be properly joined on the pipes A, and the pallet and the beam cannot be lifted in an appropriate posture.

Since the length of the rail body 2 and the loading body 3 in the front-rear direction are substantially the same, the entire structure can be made compact, and loading and unloading into the ship can be easily performed.

The front-rear drive means 4, the turning drive means 7, and the sending means 8 are not limited to the above example, and can be appropriately designed.

In the previous example, the joined body 5 includes an elevating plate 20 that can be moved up and down with respect to the front connecting plate 13 of the loading body 3, a revolving body 22 that can be turned around a vertical axis 21, and Although the elastic plate 23 is attached to the lower surface of the load member 3, the present invention is not limited thereto.
A swivel plate 22 that can be turned around, an elevating body 20 that can move up and down with respect thereto, and an elastic plate 23 attached to the lower surface of the swivel body 20 may be used.

In the above example, the number of the lifting / lowering drive means 6 is four, but the number is not limited to this, and may be three or five or more.

[0029]

As described above, according to the present invention, as described above,
The following excellent effects can be obtained. (1) It is composed of a rail, a load, a front-rear drive unit, a joined body, a lifting drive unit, a turning drive unit, and a sending unit. Since the swivel driving means for swiveling the joined body is provided, even if the pipe stacking machine is misaligned when loaded with a crane, it can be corrected to an appropriate state. (2) The joint body is provided so as to be pivotable with respect to the load, and the swing driving means for rotating the joint with respect to the load is provided. it can. That is, since it is not necessary to change the direction with a crane every time, the work efficiency is improved. (3) If there are three or more lifting / lowering driving means for raising / lowering the bonded body with respect to the load, the load is tilted back and forth or left / right with respect to the bonded body by individually operating each lifting / lowering drive means. The load can be kept horizontal even when the hull is inclined.
