Description

  The present invention relates to a shock absorber for preventing overturning or falling of a cylindrical container such as a drum can at the time of an earthquake, and a overturning / falling prevention method using the same.

  A cylindrical container such as a drum can is widely used as a storage container for raw material liquids of chemical products, lubricating oils, oils such as food, and wastes such as low-level radioactive wastes.

  There are various forms of storage of cylindrical containers such as this drum, but for example, four cylindrical containers are put in a set and placed on one pallet, and the storage space is effective. For utilization, this pallet is stacked in multiple layers in the vertical direction. However, when an earthquake occurs, the cylindrical containers placed in the upper tier may fall due to the earthquake, and in particular, the uppermost cylindrical container may fall (hereinafter, this is referred to as falling or falling). Leakage of the contents in the container may occur. If the contents are harmful to the human body, such as toxic chemicals, radioactive waste, this leakage should never occur and the container should be prevented from falling or falling when an earthquake occurs It is an important safety measure.

  Conventionally, various studies have been made to prevent tipping and falling of a cylindrical container such as a drum can, and in Patent Document 1, for example, an elongated jig body having one end detachably attached to a pallet And a pressing body attached to the other end of the jig body to contact the top surface of the drum can at one point to press the drum can against the pallet, and the jig body is the pallet The drum can fixing jig provided with the pressing means which generate | occur | produces the pressing force of the said pressing body by pulling in the direction of (4) is described.

Hereinafter, the present invention will be described based on the embodiments of the present invention. The present invention is not limited to this embodiment. Various modifications can be made to the following embodiments within the same and equivalent scope of the present invention.
Moreover, in the following description, although a drum can is mentioned and demonstrated as an example of a cylindrical container, this invention can be applied if it is not only a drum but if it is a cylindrical container.

1. Shock absorbing material for preventing overturning of cylindrical container According to an embodiment of the present invention, a shock absorbing material for preventing falling and falling of a cylindrical container (hereinafter, may be simply referred to as shock absorbing material) will be described with reference to the drawings. Do. 1 to 3 are schematic perspective views of shock absorbers according to a plurality of embodiments of the present invention.

  As apparent from FIGS. 1 to 3, the shock absorber 1 has a surface (fall preventing surface) 2 placed on the top of the drum and an insertion portion 3 of a hollow body having a predetermined thickness on the surface. . The insertion portion 3 of this hollow body has four protrusions 4 that project in a cruciform manner outward from the center of the fall prevention surface, and the protrusions 4 are connected by an arc 5 respectively. As shown in FIG. 4 and FIG. 5 (in FIG. 5, the shock absorber material 1 is shown from the drop prevention surface as a dotted line), the insertion parts 3 of the shock absorber material 1 are spaced apart from each other on the pallet 10. The four drums 11 can be inserted into the central gap 12 of the four drums 11 to prevent the four drums 11 from falling and falling. Therefore, the arc 5 is in contact along the outer periphery of the drum 11.

  The thickness t of the insertion portion (see FIG. 3) is the insertion depth of the shock absorber 1 into the drum 11, and this thickness t is a thickness that can prevent the four drums from falling and falling. There is no particular limitation if it is, but if it is thicker than necessary, the workability for inserting the shock absorber 1 is reduced, and the manufacturing cost thereof is expensive, so 40 to 100 mm is a guideline.

  Further, the shape of the fall prevention surface 2 of the shock absorber is not limited as long as the shock absorber 1 can be placed on the top of the drum 11, and may be, for example, a square such as a square or a circular flat plate. From the viewpoint of ease of positioning (workability) of the insertion of the shock absorbing material 1 into the central gap 12 of the drum can 11, the similar shape in which the insertion portion 3 is expanded parallel to the plate-like anti-drop surface 2 from its center (Hereinafter, referred to as enlarged similar shape) is preferable.

  Furthermore, the insertion portion 3 of the shock absorber 1 may be manufactured as a hollow body by, for example, plastically working a steel plate and bonding the members by an appropriate means. The material of the shock absorber is not limited to steel (mild steel), but may be galvanized steel or aluminum, and may be plastic as long as the required strength can be ensured.

  As described above, this shock absorber 1 can prevent the falling and falling of the drum by simply inserting the insertion portion 3 into the gap 12 at the center of the four drums 11 on the pallet 10. That is, the mounting work of the shock absorber 1 according to the present invention is not a time-consuming work of fixing the jig on the pallet on which the drum can is mounted from the top of the drum can as in the prior art. Since this is an operation that does not require the simple skill of inserting the equipment 1, the installation can be performed in a short time, and the workability for preventing overturning / falling is extremely good.

2. Although inserting the insertion portion 3 of the shock absorber 1 into the gap 12 at the center of the four drums 11 on the pallet 10 can prevent the drums from falling over or falling to a certain extent, reliable falling It is desirable to fasten the outer circumferences of the four drums with the fastening means 13 so that the four drums can be integrated to prevent falling.

  The securing means 13 has a strength capable of preventing the falling and falling of the drum can, and is not particularly limited as long as the drum can 11 can be secured, but a belt-like thing (hereinafter referred to as a securing belt), , Lashing belt can be used. In addition, the lashing position of the height direction of the drum can by the lashing means 13 is preferably slightly above the upper ring of the drum. In addition, it is desirable to provide a corner protector 20 at each corner of the drum to protect the drum 11 from the fastening means 13 (see FIGS. 4 to 5).

3. Fixation of securing means When a large earthquake occurs, many aftershocks often follow the main shock. Therefore, the fall and fall of the drum can be prevented not only for the main shock but also for aftershocks. That is, even after the prevention of the falling and falling of the drum against the shaking of the main shock, it is necessary to be able to prevent the falling and falling of the drum against the shaking of many aftershocks. Therefore, it is preferable to fix the binding means 13 to the drum 11 by the fixing means (fixing tool) so that displacement of the fastening means does not occur due to the shaking of the main shock.

  Any fixing means may be used as long as the fixing means 13 can be fixed, but it may be easily attached to the drum 11, for example, adhesive tape or steel drum if a magnet is used. It can be mentioned. Although the magnet may be attached to the lashing belt itself as the use of the magnet, the magnet may be incorporated in the corner protector 20 provided at the corner portion 14 of the drum can 11 on the pallet.

  As an example of the corner protector 20 incorporating a magnet, the one shown in FIG. 6 accommodates a flexible plate-like magnet 21 in an elastic resin-made envelope-type storage bag 22, and the envelope-type storage bag 22. The lashing belt 24 (for example, a lashing belt), which is a lashing means, is inserted into the lashing belt insertion portion 23 provided on the outer side of the belt. Here, the resin having elasticity refers to one having elasticity to such an extent that it can be bent along the corner portion of a cylindrical container such as the drum can 11 or the like.

  If this corner protector 20 is provided at the corner portion 14 of each drum, in addition to preventing overturning and falling due to aftershocks, even if the fastening belt 24 is gradually extended due to secular change and the fastening is somewhat loosened, It is possible to prevent the fall and fall of the drum can 11 with almost no loss of the securing force of the binding belt 24.

4. Prevention of Overturning and Falling when Stacking Drum Cans in Multiple Stages Next, regarding prevention of falling and falling when stacking drums up in multiple stages, based on an example in which four drums are placed on one pallet. explain.

  FIG. 7 is an explanatory view of a method for preventing overturning / falling of a plurality of stacked drums according to an embodiment of the present invention, wherein 12 pallets provided with pallets on which four drums are mounted Are stacked vertically in three stages. Then, as is clear from this figure, the embodiment of FIG. 7 inserts the shock absorber material only into the drums on the 10 pallets arranged on the outer peripheral portion among the drums on the top 12 pallets. , It is something which is locked by the locking means. In the embodiment of FIG. 7, the shape of the anti-drop surface is a square, but as described above, it is preferable from the viewpoint of the workability of mounting the shock absorbers that the shape is enlarged.

  As described above, among the drums stacked in a plurality of stages, only the drums on the pallet disposed on the uppermost and outer peripheral portion are sufficiently effective only by applying the overturn / drop prevention measures according to the present invention. be able to. It goes without saying that it is more effective if all the drums stacked in the upper, middle and lower layers are prevented from falling and falling due to aftershocks as well as the main shock, but to the extent to which falling and falling prevention measures are taken The cost may be determined appropriately in consideration of costs.

5. Pallet In the present invention, a pallet on which a cylindrical container such as a drum can be placed is not particularly limited, but a pallet partitioned into four sections as shown in FIG. 8 is preferable. In this pallet, as shown in FIG. 8, four fasteners 15 are provided by welding at predetermined positions in the four sections of the pallet. And since the gap 12 at the center of the four drums can be formed at a predetermined position simply by placing the four drums on the four blocks of the pallets 15 respectively, the positions of the four drums can be obtained. There is no need to perform adjustment each time, and the shock absorber can be easily inserted into the gap 12.

  Next, an example will be described. Here, although the case where a drum can is used as a cylindrical container is demonstrated, it is the same even if it is another cylindrical container.

  Four steel drums 11 were placed on the pallet 10 provided with the fasteners 15 shown in FIG. 8 separately from each other, and the pallets 10 were stacked in three stages in the vertical direction. Then, as shown in FIG. 4, the shock absorber material 1 according to the present invention is inserted into the gap 12 at the center of the four drums 11 on the uppermost pallet 10, and as shown in FIG. Corner protectors 20 for fixing the binding belts 24 by the plate-like magnets 21 were provided at the corners of the drums 11 respectively. Next, strong vibration was artificially applied to the base on which the lowermost pallet 10 was placed, and the state of the falling and falling of the drum can 11 was observed. It was confirmed that the shock absorber and the fall / fall prevention method of the present invention are also effective for earthquakes with large seismic intensity, since there was no drum can falling from the above.
