FIG. 6 is a schematic diagram showing the swivel state of the radioactive substance storage container transport facility according to the present invention.

  As shown in FIG. 1, the radioactive substance storage container storage facility includes a storage area 3, an incidental area 4, and a transport passage 5 through which the radioactive substance storage container 1 is transported. The radioactive substance storage container 1 is fixed to a storage stand 2 and arranged and stored in a radioactive substance storage container storage facility. The storage area 3 is provided with an air supply port and an exhaust port for appropriately removing heat radiation from the radioactive substance storage container 1 by natural heat radiation.

  The radioactive substance storage container 1 is first carried by the trailer 7 into the incidental area 4 of the radioactive substance storage container storage facility.

  In the incidental area 4, the radioactive substance storage container 1 loaded on the trailer 7 is suspended from the trailer 7 using the overhead crane provided in the incidental area 4 from the trailer 7, and the radioactive substance storage container 1 is temporarily stored (temporary storage). Etc. are performed. Further, in the incidental area 4, building incidental facilities 8 such as a power supply necessary for equipment repair and management control room and facility maintenance are also arranged. In addition, the floor surface of the storage area 3, the incidental area 4, and the conveyance path 5 is set to the same level.

  The radioactive substance storage container 1 that has been temporarily placed is transported to the inspection stand 21 and installed therein, where various inspections for starting storage are performed. The radioactive substance storage container 1 that has passed the inspection is installed on a vertical storage stand 2 that is a stand for storage.

  As shown in FIG. 2, the radioactive substance storage container transport facility of the present invention includes a transport vehicle 10 and an auxiliary vehicle 11. The transport vehicle 10 and the auxiliary vehicle 11 can be driven independently and are connected by a flexible compressed air supply pipe 12. In the auxiliary vehicle 11, the compressed air generated by the air compressor 19 provided in the auxiliary vehicle 11 passes through the compressed air supply pipe 12, the air motor of the conveyance vehicle 10, the air pallet 14, the drive wheel 15 and the vertical drive device of the swivel pin 18, etc. Supply to a brake mechanism (not shown) is performed.

  The transport vehicle 10 includes a transport base 13 for mounting the radioactive substance storage container 1 together with a storage stand 2 fixed to the lower part thereof, an air pallet 14 installed at the lower part of the transport base 13, and a drive wheel 15 for driving the transport car 10. The driving device 16 is provided. The drive wheel 15 of the transport vehicle 10 includes a vertical drive device that moves up and down by supplying compressed air to a cylinder-like airbag provided at a mounting portion of the drive wheel 15. The transport vehicle 10 is a self-propelled type that drives the drive wheels 15 by an air motor provided in the drive device 16. As the air motor, a turbine type that is rotated by compressed air, a piston type that is driven by a piston that reciprocates in a cylinder, and the like are used. In addition, the transport vehicle 10 is provided with one guide wheel 17 on each side of the front end of the transport table 13 for use when moving when the radioactive material storage container 1 is not mounted. A guide is provided when the container 1 is inserted into an insertion portion provided in the lower part of the storage stand 2 on which the container 1 is mounted. The drive device 16 also has a guide wheel 17 on the side opposite to the drive wheel 15. In addition, a vertical drive device is provided in which the swivel pin 18 is moved up and down to ensure stability during turning when the transport vehicle 10 and the drive device 16 are turned. The turn pin 18 is installed on the floor surface during turning. It becomes a turning axis.

  The air pallet 14 of the transport vehicle 10 blows out the compressed air supplied from the auxiliary vehicle 11 from an air outlet provided at the lower part of the air pallet, and forms a film of air between the floor and the friction coefficient. Although it depends on the condition of the floor surface, the load required for movement can be reduced from about 1/1000 to 1/100. Thereby, even if the radioactive substance storage container 1 has a large weight exceeding 100 t, it can be transported by equipment having a small driving force. Furthermore, compared with the overhead crane which is the conventional conveyance equipment, it has a low lift and can eliminate the influence of dropping.

  As the system configuration of this air pallet, there are roughly two systems as shown in FIGS. FIGS. 9 and 10 show a cross section of a portion below the support 30 of the air pallet system of this embodiment.

  In the air pallet system shown in FIG. 9, a donut-shaped airbag that surrounds the entire circumference is attached to the lower surface of the support base, and compressed air 27 is blown between the airbag 29 and the airbag through the support base 30. A thin air film 28 is formed between the air bag 29 and the floor surface to greatly reduce the frictional force due to the load 25 when the radioactive substance storage container, which is a heavy object, is moved.

  In addition, the sectional view of the air pallet system shown in FIG. 10 is such that a donut-shaped diaphragm 31 that surrounds the entire circumference is attached to the lower surface of the support base 30. The diaphragm 31 is swelled by the compressed air 27 supplied through the support base 30, and a thin air film 28 is formed between the diaphragm 31 and the floor surface by the compressed air 27 discharged from the hole of the diaphragm 31, which is similar to FIG. In addition, the frictional force due to the load 25 when moving the radioactive material container, which is a heavy object, is greatly reduced. It is to reduce.

  The auxiliary vehicle 11 is a self-propelled type that is equipped with an air compressor 19 and a power source 20 for supplying compressed air to the transport vehicle 10 and is driven by the same motor as the transport vehicle 10. The power source of both the transport vehicle 10 and the auxiliary vehicle 11 is compressed air generated by an air compressor 19 mounted on the auxiliary vehicle 11, and the driving wheels 26 of the auxiliary vehicle 11 are driven by this compressed air.

  After fixing the radioactive substance storage container 1 to the storage stand 2, the entire storage stand 2 is transported from the incidental area 4 to the storage area 3 by the radioactive substance storage container transport facility 9.

  As shown in FIG. 3, the carrier 10 of the radioactive substance storage container transport facility 9 is operated to move, and an air pallet 14 is provided at the insertion port of the storage stand 2 fixed to the lower part of the radioactive substance storage container 1. By inserting the transport table 13, the transport state is adjusted as shown in FIG. The transport table 13 is divided into two parts with a predetermined interval, and each is formed integrally with the driving device 16. This interval can be inserted while avoiding the support provided at the center of the storage stand 2. One driving wheel 15 is provided on each side of the driving device 16 corresponding to the carrier 13 that is divided into two. The air pallet 14 is a part as shown in FIGS. 9 and 10, and three parts are provided on each of the transporting bases 13 that are divided into two parts. The entire conveyance table 13 is floated by the principle shown in FIG. The size and number of the air pallets 14 are set according to the weight of the conveyed object. The carrier 13 is floated by the center of gravity of the radioactive substance storage container 1 and the air pallet 14 installed on the carrier 13 when inserted to a predetermined position in the storage stand 2 fixed to the lower part of the radioactive substance storage container 1. It has a structure where the centers of gravity coincide.

  Moreover, when inserting the conveyance stand 13 in the storage stand 2, compressed air is not supplied to the air pallet 14, but it is in a deflated state.

  Next, as shown in FIG. 5, the carrier 13 is lifted by sending compressed air into the air pallet 14. At the same time, the driving wheel 15 installed in the driving device 16 is also pushed down by inflating the air bag provided in the driving wheel mounting portion by supplying compressed air, to the floor surface necessary for obtaining driving force. In this state, the guide wheel 17 is in a floating state.

  In the radioactive substance storage container transport facility 9, the transport vehicle 10 and the auxiliary vehicle 11 move together in the transport passage 5 while the radioactive substance storage container 1 is moved to the arrangement position, but the radioactive substance storage container 1 is moved in the storage area 3. When the vehicle 10 arrives at the position of the conveyance path 5 to be stored, the conveyance vehicle 10 leaves the auxiliary vehicle 11, and the conveyance vehicle 10 turns while carrying the radioactive substance storage container 1 and conveys it to a predetermined storage position. As a result, the auxiliary vehicle 11 only needs to travel in the transport path 5, and when the radioactive substance storage container 1 is disposed, the transport vehicle 10 is transported only by the transport vehicle 10, so that the space required for transport can be reduced and the radioactive material can be reduced. The substance storage container storage facility can be made compact.

  As shown in FIG. 6, the direction change from the conveyance path 5 to the storage area 3 of the conveyance vehicle 10 is temporarily stopped from the traveling state, and the supply of compressed air to the airbag of the mounting portion of the drive wheel 15 is stopped in the floating state. By doing so, the driving wheel 15 is levitated from the floor surface. Subsequently, the drive wheel 15 is supported by a rotating shaft that changes the moving direction, and the direction of the traveling direction is changed to a direction of turning about a turning axis formed by pushing the turning pin 18. Again, the driving wheel 15 is lowered from the driving device 16 so as to press against the floor surface, and the driving wheel 15 is rotated in the moving direction, thereby turning in the moving direction indicated by the arrow. The swivel pin 18 is provided with a vertical drive device that is driven up and down so as to be pressed against the floor surface by compressed air. The swivel pin 18 serves as a swivel axis, and stability during swiveling is increased and swivel is ensured.

  The radioactive substance storage container 1 and the storage stand 2 that have reached a predetermined position in the storage area 3 stop the supply of compressed air to the air pallet 14 and land the radioactive substance storage container 1 and the storage stand 2 from the floating state. Subsequently, the transport table 13 is retracted and the transport table 13 is pulled out from the lower part of the storage stand 2, and the radioactive substance storage container 1 is in a storage state. Thereafter, various monitoring facilities for monitoring that the storage state is healthy are attached, and storage is started. Carrying out the radioactive substance storage container 1 from the radioactive substance storage container storage facility after the storage is completed is performed by reversing the carrying-in procedure.

  With the building configuration of the radioactive substance storage container storage facility employing the radioactive substance storage container transport facility 9 as described above, the ceiling height of the storage area 3 can be reduced as compared with the conventional method using an overhead crane, At the same time, since the load for transporting the radioactive substance storage container is supported only by the floor surface, the structure of the building can be simplified, and the construction work and cost of the facility can be greatly reduced.

  The wall thickness and ceiling thickness of the building constituting the radioactive substance storage facility are set to such an extent that leakage of radiation from the radioactive substance storage container to the outside is sufficiently reduced. Furthermore, the area required for transportation can be reduced, and the storage facility can be made compact. The radioactive substance storage container 1 is a metal or concrete container in which radioactive substances such as radioactive waste generated at nuclear power plants and spent fuel assemblies are stored in a sealed state.

  As described above, according to this embodiment, the auxiliary vehicle 11 can be moved only in the transport path 5 and the radioactive substance storage container 1 can be transported to the storage area 3 at a predetermined position only by the movement of the transport vehicle 10. Provide a self-propelled transport vehicle, radioactive material storage container transport equipment and radioactive material storage container storage facility that can reduce the area required for transport by simplifying transport start work and improving the stability of the turning state during transport It is something that can be done.

  FIG. 7 is a sectional view showing another structure of the radioactive substance storage container transport facility of the present invention. As shown in FIG. 7, the transport vehicle 10 of the radioactive substance storage container transport facility 9 has the same configuration as that of the first embodiment, but the compressed air is supplied to the transport vehicle 10 in the incidental area in the radioactive substance storage container storage facility. Compressed air provided at predetermined intervals from compressed air pipes 22 provided at predetermined intervals from the air compressor 19 provided separately to the building 4 or the building ancillary facilities 8 below the floor or above the transport passage 5 in the building. The point from which the auxiliary vehicle was eliminated by supplying from the supply port 23 is different from Example 1.

  With this configuration, the auxiliary vehicle 11 is not required, and the radioactive substance storage container transport facility can be simplified and considerably reduced in size. In addition, since it is necessary to change the compressed air supply pipe 12 every time a certain distance is conveyed for the supply of compressed air, the operation is slightly more complicated than that of the first embodiment, and the time required for the conveyance. Although it may be slightly longer, the same effects as in the first embodiment can be obtained.

  FIG. 8 is a sectional view showing another structure of the radioactive substance storage container transport facility of the present invention. As shown in FIG. 8, the transport vehicle 10 of the radioactive substance storage container transport facility 9 has the same configuration as that of the first embodiment, but the power source of the auxiliary vehicle 11 is a diesel engine with respect to the power source 20 of the first embodiment. 24. With this configuration, the auxiliary vehicle 11 can be made smaller than the auxiliary vehicle 11 shown in the first embodiment, and the same effects as those of the first embodiment can be obtained. In addition, since the exhaust gas from the diesel engine 24 is discharged into the facility, it is necessary to provide a device for removing the exhaust gas.
