Abstract

PURPOSE:To efficiently save a storing space of drum cans, by vertically stacking a plurality of drum cans and connecting the same with each other by means of palettes intervening therebetween. CONSTITUTION:A palette P is provided with four circular recesses on both upper and lower surfaces thereof, respectively. Each recess is formed in such a size that the peripheral rim portion of drum cans is appropriately received therein. In each recess, there are disposed a central pushbutton 4 and four connecting plates 2 which serves as connecting means between the palette and can and extend radially from the central pushbutton. The palette is also provided with four bores 3 at its corner edges, through which anchor bolts are inserted and threaded into the floor. When the end of the drum can is placed in the recess, the pushbutton is depressed due to the tare of the can. As a result, while a roller 8 of the connecting plate 2 rides over the sloped side wall of the pushbutton, the connecting plates are displaced inwardly to the pushbutton because they are biased toward the center of the recess by means of the spring 7. At this time, a hook 9 formed at the opposite end of the connecting plate is engaged with the rim portion of the drum can to thereby establish a secure connection between the palette P and the drum can D. Since the lowermost palette is anchored to the floor by bolts 10 inserted through the bores 3, a plurality of the drum cans stacked by intervention of palettes are, as a whole, securely fixed on the floor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pallet suitable for palletized storage of drums, such as drums filled with radioactive waste.

[Prior Art] Conventionally, drums filled with radioactive waste have been stored on pallets in three-tiered storage using flat pallets. In order to increase storage space efficiency, it is desirable to add more stages, but due to earthquake resistance and other issues, conventionally 3 stages were used.
It stayed in the stacks.

[Problems to be Solved by the Invention] The above-mentioned conventional technology has not been particularly devised in terms of earthquake resistance, and there is a problem in terms of storage space efficiency in that drums must be stored in three or less stacks. Ta.

An object of the present invention is to provide a drum storage pallet that improves earthquake resistance when storing drums on pallets, increases the number of stacked pallets, improves storage space efficiency, and reduces storage area. .

[Means for Solving the Problems] The drum storage pallet of the present invention has recessed holes large enough to fit the rims of the drums on both upper and lower surfaces, and the rims of the drums are inserted into the recessed holes. The device is characterized in that it has a connecting mechanism that separates from the rim of the drum by inserting and pulling out from the recessed hole, and has a claw that locks onto the rim of the drum when the drum is seated.

[Function] When inserting or pulling out a drum into the recessed hole of a pallet, the claws separate from the rim of the drum, and the drum and pallet are not connected, but when the drum is inserted into the recessed hole. When the pallet is seated, the claws are caught on the rim of the drum, and the pallet and the drum are connected, and the connection is not broken due to lateral shaking or diagonal upturning during an earthquake, and the multi-level stacking of drums is prevented. Earthquake resistance is improved.

[Example] Fig. 1 is a plan view of a drum storage pallet P according to an embodiment of the present invention, Fig. 2 is a side view thereof as seen from direction A, and Fig. 3 is a side view thereof as seen from direction B. It is. Four recessed holes 1 large enough to fit the rims of drums are provided on both the upper and lower surfaces of the pallet P, and each recessed hole 1 has a connecting plate 2 and a push button 4 for connecting the drum and the pallet. In addition, holes 3 are provided at the four corners of the pallet for passing bolts for connecting the pallet to the storage floor surface. Further, the pallet P is provided with a hole F into which a fork of a forklift is inserted.

5 to 7 show the connecting plate 2, the push button 4, and their related structures. At the bottom of the recessed hole 1, grooves 1° are formed radially, and a connecting plate 2 is disposed in each groove 1'. In FIG. 5, only one of the connecting plates 2 is illustrated. A bottle 6 fixed to the groove 1'' passes through the elongated hole 5 provided in the connecting plate 2, so that the connecting plate 2 is fixed to the groove 1'.
It is supported slidably in the direction of. The other end of the tension spring 7 whose #1 end is pinned to the groove 1' is locked to the connecting plate 2. In the center of the recessed hole 1 where the radial grooves 1° meet each other, an extendable push button 4 is installed which is always urged in the projecting direction by a built-in push spring 4°. push button 4
has a conical slope as shown in the figure. The connecting plate 2 has a roller 8 at its inner end, and the spring 7 biases the connecting plate 2 so that the roller 8 always comes into contact with the push button 4. A claw 9 is formed at the outer end of the connecting plate 2 for locking the rim of the drum.

The mechanism described above is based on the recessed holes 1 on both the upper and lower surfaces of the pallet P.
It is set in.

To describe the operation, when the drum is not attached,
The connecting plate 2 and the push button 4 of the pallet P are in the state shown in Fig. 6, but when the end of the drum is inserted into the recessed hole 1 of the pallet P, the push button is pushed by the weight of the drum as shown in Fig. 8. 4 is pressed, and in conjunction with this, the roller 8 moves on the slope of the push button, and the connecting plate 2 moves in the direction closer to the push button 4, and the claw 9 catches on the rim of the drum. , the eighth in which the drum truck and pallet P are connected.
It will be in the state shown in the figure. Conversely, when the drum car is lifted straight upward from the state shown in FIG. 8, the pawl 9 comes off from the rim of the drum and the connection between the drum car and the pallet P is released by the reverse operation. By selecting the shapes and dimensions of the connecting plate 2 and the push button 4, it is possible to design the above operation.

FIG. 4 shows a state in which drums are connected and stacked in multiple stages using the pallet P as described above. Lower pallet P
The entire structure is fixed to the floor by passing bolts 10 installed in the floor through the bolt insertion holes 3.

9 and 10 show another embodiment of the present invention, in which the pin is pivotally mounted in the groove 1 as described above, and the pressure spring 1 is
A connecting lever 11 is provided which is always urged upward at 2. When the drum can is put into the recessed hole 1 of the pallet, the lever 11 is pushed by the drum can, and its claw part catches on the rim part of the drum can as shown in Fig. 10, so that the drum can and the pallet are connected. Also, the claws can be removed from the drum rim by lifting the drum straight up.

[Effects of the Invention] According to the present invention, multi-tiered drums are connected to each other via pallets to form an integrated structure, so earthquake resistance in palletized storage of drums can be improved, and The ability to stack in multiple stages has the effect of improving storage space efficiency.
