Description

DETAILED DESCRIPTION OF THE INVENTION The present invention can be used, for example, when storing a submarine cable guide ring, which is connected sequentially to a submarine cable burying device in a flexible manner to constitute a submarine cable guide trough, on a ship or on land. This invention relates to a pallet for stacking guide rings.

Conventionally, when stacking this type of guide ring (hereinafter also simply referred to as ring) for the purpose of storage, transportation, or easy handling when constructing a guide pipe, the very common bale stacking method was used. However, in the stacked state of the rings due to this, the ring itself has an unstable cylindrical cage shape, so there is a risk that the stacked state is likely to collapse. Particularly on cable-laying ships where these cables are handled, the above-mentioned dangers are exacerbated because the ship's hull may oscillate.

In addition, there are various protrusions on the outer periphery of this ring, and these protrusions can become entangled in the cages of adjacent rings. It also has the disadvantage that it hinders the smoothness of the work.

Therefore, it was considered to provide a rack that could store a large number of rings by type and in multiple stages, but the number of rings (approximately 500 mm in diameter and approximately 500 mm in height) loaded onto a laying ship during submarine cable installation was limited. There are about 1,000 pieces, so it is expensive to manufacture the racks, and a large amount of space on the ship is also consumed in order to efficiently move the rings in and out.

Furthermore, when the rings are transported from the laying ship for onshore storage and maintenance, the work must be done manually one by one.

In view of the above-mentioned problems, the present invention uses a simple structure to prevent rings from becoming entangled in a stable piled-up state and in the same state, and to satisfactorily eliminate bulkiness when not in use. A certain number of rings can be transported together using a crane or forklift.

The present invention provides a pallet for stacking guide rings having a plurality of small ring portions at symmetrical positions on the outer periphery, on the upper surface of a base plate on which the guide rings are stacked vertically in the form of a cylindrical column. is characterized in that a plurality of support rods are erected at relative intervals such that they can penetrate each of the small ring portions of the guide ring.

Below, specific examples of the palette according to the present invention are as follows:
This will be explained with reference to the drawings.

In the figure, 1 is a base plate, and this base plate 1 includes a top plate 3 having an anti-slip shape 2 due to unevenness or a rough surface, a plurality of back plates 4, and the top plate 3.
In this base plate 1, the frame member 5 such as an angle member interposed between the back plate 4 is welded to each other, and has a substantially square shape even when the four corners are rounded. The top plate 3 forms a single upper surface of the same disc 1, and the plurality of back plates 4 are arranged near the outside of the lower surface of the same disc 1, and a part of the lower surface is formed into a hollow rectangular shape. becomes.

6A, 6A', 6B, 6B', 6C, 6C', 6
D and 6D' are each a pair of support rods made of a metal material such as a hollow pipe shape or a solid rod shape, and each of these pair of support rods 6A, 6A' to 6
D and 6D' are erected at predetermined intervals on the above-mentioned base plate 1 via the illustrated screw-in structure 7.

A part of the screw-in structure 7 mentioned above is the threaded rod part 8 formed at the lower end of each of the support rods 6A, 6A' to 6D, 6D', and the other parts are provided on the base plate 1 in correspondence with the threaded part 8. The two parts 8 and 9 are screwed together to maintain the above-mentioned upright state.

Reference numeral 10 indicates a hook ring attached to the outer surface of the four corners of the rounded base plate 1, and 11 indicates the base plate 1.
These legs are attached to the four corners of the lower surface, and the legs 11 are made of channel material bent into an L shape.

Reference numeral 12 in the figure is a guide ring which is used as one object to be piled up in the present invention, and regarding this ring 12, for example, Utility Model Application No. 53-148289,
There is a detailed explanation in No. 148290, etc., so I will only give a brief explanation here, but it has a cylindrical cage shape and is provided so that it can be opened and closed in half by means of a shaft pin 13 and a lock pin 14 located in symmetrical positions. Ring 12
are located at the upper and lower parts of the outer circumference and correspond to the outer sides of the shaft pin 13 and the lock pin 14,
Each has small ring portions 15 and 16 that can be opened and closed in a hoe shape when the ring 12 is opened and closed.

The distance between each pair of support rods 6A, 6A' to 6D, 6D', which is set at a predetermined distance in the above, is set corresponding to the distance between these small ring portions 15, 16.

In the present invention consisting of the above-described embodiment, as clearly shown in FIGS. 1 and 3, the guide rings 12 are stacked vertically on the base 1, and at this time, each ring 12 small ring portions 15, 16 are respectively penetrated by the pair of support rods 6A, 6A' to 6D, 6D', and their stacked state is
Since they are held by A, 6A' to 6D, 6D', the above-mentioned stacking condition will not occur even if each ring 12 is stacked in a static location or in a rocking location such as on a ship. Collapse can be prevented.

Moreover, in the above stacked state, each support rod 6A, 6
Each ring 12 is held in an orderly manner in the vertical direction via A' to 6D, 6D', and it is possible to prevent mutually adjacent stacked rows from intertwining, so the operation of removing each ring 12 from the base plate 1 is also Each support rod 6A, 6A'~
This can be done smoothly using 6D and 6D' as guides.

In addition, the base plate 1 and each support rod 6A, 6A' to 6D,
6D' has a smaller bulk than large three-dimensional structure racks, and when not in use, the base plate and each support rod can be disassembled in the screw-in structure 7, making it more compact and reducing bulk. Therefore, the problem of space consumption can be satisfactorily solved.

Further, since the base plate 1 has legs 11 and hanging rings 10 that can form a space with the ground surface, pallets can be easily transported via a crane or a forklift.

In addition, in the above example, each constituent member of the pallet of the present invention is made of metal, but it is not limited to this, and each of these members may be made of FRP or other synthetic resin having excellent mechanical strength and corrosion resistance. may be formed.

In addition, each support rod 6A, 6A' to 6D, 6D' is
As shown in FIG. 4, which is represented by the support rod 6A, a fitting convex portion 17 provided at the lower end of the support rod 6A and a corresponding fitting recess 18 provided on the base plate 1 are fitted. The structure 19 may allow the supporting rods to be attached to and removed from the base 1, or the support rods may be fixedly mounted on the base 1 depending on the case.

Furthermore, regarding the guide rings, those other than those shown in the drawings can be used to maintain their stacked state in the same manner as described above.

As explained above, when using the pallet of the present invention, not only can a large number of guide rings be stacked vertically on the base plate, but also each small ring at a symmetrical position on the outer circumference of the guide ring can be stacked by each support rod. Since it penetrates through the small rings, it will not collapse even when the ship is rolling or pitching, and it will also prevent the guide rings from slipping in the direction of rotation, preventing adjacent small rings from getting entangled with each other. An extremely stable and orderly stacking condition can be ensured.

Also, when removing the stacked guide rings, the support rod and the small rings are in a fitted state, so the directionality when removing them is determined, and collisions of the small rings do not occur at this time. , easy to work with.

Furthermore, the small ring part of the guide ring is provided in advance for passing the tow rope, etc., and this small ring part is used to stack and store the guide rings on the pallet. There is no need to drill new holes in the pallets, and each support rod for the pallets needs to be thin and small in number, allowing the pallets to be supplied at low cost, reducing the hassle of stacking and storing a large number of guide rings. It can be done efficiently and without much effort.
