Nuclear fusion and nuclear fission can release a large amount of nuclear energy, and the nuclear energy is converted in the way of nuclear energy-mechanical energy-electrical energy to generate nuclear power for external use.

[0003] At present, the nuclear power production method adopted by the world is nuclear fission, which requires radioactive raw materials for nuclear fission. With the commissioning of nuclear power units, the number of radioactive materials that need to be transported is also gradually increasing. Due to the radioactivity and penetrability of radioactive materials, when transporting radioactive materials, they need to be placed in professional storage and transportation containers to temporarily store and transport radioactive materials.

However, when the radioactive material storage and transportation container is moved to the storage platform, it cannot be hung on the storage platform, so it is not convenient to move from the storage platform to the transport vehicle, which makes the transportation process time-consuming and the transportation efficiency low.

[0032] In the relevant technology, radioactive materials can continuously and spontaneously emit x, alpha, beta, gamma rays and neutron flux that are invisible to the naked eye. These materials contain a certain amount of natural or artificial radioactive elements. The radioactivity possessed by radioactive materials is widely used in industry, agriculture, medical care and other fields, and has important value.

[0033] In order to ensure the safety of radioactive materials during transportation and prevent radioactive pollution of the environment and harm to human body, radioactive materials need to be placed in radioactive material storage and transportation containers, which can effectively block the penetration of radiation.

[0034] In the process of moving the radioactive material storage and transportation container from a warehouse to a destination, the container is first moved from the warehouse to a storage platform, and then from the storage platform to a transport vehicle. The transport vehicle moves the radioactive material storage and transportation container to the destination for the use of the radioactive material.

Figure 2 yes Figure 1 The structure shown in FIG. 1 is a schematic diagram of the structure in which the suspension device is removed. Figure 3 yes Figure 2 Schematic diagram of the structure without the connecting parts shown in the figure.

[0036] See also Figures 1 to 3 The present application provides a radioactive material storage and transportation container loading and unloading tool, which includes: a support rod 100, a limiter 200 and a hanging device 300; the limiter 200 is arranged at both ends of the support rod 100, and a hoisting hole 211 and a connecting hole 213 are opened on the limiter 200, the hoisting hole 211 is used to connect with an external hoisting device; the connecting hole 213 is used to carry the radioactive material storage and transportation container; the limiter is provided with a hanging part; the hanging device 300 is arranged on the limiter 200 through the hanging part, and the hanging device 300 is used to limit the storage platform so that the radioactive material storage and transportation container is hung on the storage platform; wherein the hanging device 300 is located between the hoisting hole 211 and the connecting hole 213, and the hanging part, the hoisting hole 211 and the connecting hole 213 are arranged at intervals.

[0037] When the radioactive material storage and transportation container needs to be moved, the suspension device 300 is limited on the limiting member 200 through the suspension part. The radioactive material storage and transportation container loading and unloading tool (hereinafter referred to as the loading and unloading tool) is lifted to the radioactive material storage and transportation container (hereinafter referred to as the storage and transportation container) (not shown in the figure) by a lifting device (not shown in the figure), and then connected and limited to the storage and transportation container through the connection hole 213 on the loading and unloading tool.

[0038] Afterwards, the loading and unloading tool and the storage and transportation container thereon are hoisted by hoisting equipment to move the loading and unloading tool and the storage and transportation container to the storage platform.

[0039] When the storage and transportation container is moved to the storage platform, the suspension device and the storage platform are limited, so that the storage and transportation container is suspended in the storage platform. The loading and unloading tool can reduce the steps of transferring the storage and transportation container to the transport vehicle and improve the transfer efficiency of the storage and transportation container.

[0040] See also Figure 1 For ease of understanding, the state of the radioactive material storage and transportation container loading and unloading tool when in use is used as a reference, the up and down direction of the loading and unloading tool is the vertical direction below, the length direction of the support rod 100 is the horizontal direction below, and the direction perpendicular to the vertical and horizontal directions is the longitudinal direction below.

[0041] Figure 4 yes Figure 3 A structural schematic diagram of another perspective of the structure described in .

[0042] See also Figures 1 to 4 In this embodiment, the support rod 100 extends in the horizontal direction to support the two limit members 200, so that the two limit members 200 can be connected and suspended to the storage and transportation container. During use, the support rod is only subjected to the horizontal force in the horizontal direction applied by the limit members 200. The support rod is a two-force rod and is not subjected to the bending load in the vertical direction.

[0043] In some embodiments, the support rod 100 is a columnar or tubular structure. In other embodiments, the support rod 100 is a round tube, so as to be threadedly connected with the stopper 200.

[0044] Figure 5 It is a structural schematic diagram of a limiting component of a loading and unloading tool of the utility model. Figure 6 yes Figure 5 A structural schematic diagram of another perspective of the structure described in .

[0045] See also Figures 1 to 6 In this embodiment, the limiting members 200 are disposed at both ends of the support rod 100 and extend vertically. The limiting members 200 are used to connect and limit with the storage container, the lifting equipment and the storage platform.

[0046] The limiting member 200 includes a limiting plate 210, and the limiting plate 210 is connected to both ends of the support rod 100. A hoisting hole 211, a hanging portion, and a connecting hole 213 are provided on the limiting plate 210, and the hanging device 300 is connected and limited on the limiting plate 210 through the hanging portion. The lifting equipment can be connected to the limiting plate 210 through the hoisting hole 211. The limiting plate 210 can be connected to the storage container through the connecting hole 213. The limiting plate 210 can be limited in the storage platform through the hanging device 300, so that the storage container is limited and suspended in the storage platform.

[0047] The limiting plate 210 is triangular in shape, and in the extension direction of the support rod 100, the limiting plate 210 extends away from the support rod 100, and the length of the limiting plate 210 along the direction perpendicular to the extension direction of the support rod 100 gradually increases. The triangular shaped limiting plate 210 can effectively improve the structural strength of the limiting plate 210, and facilitate the decomposition and offset of the gravity of the storage container during hoisting and hanging.

[0048] In this embodiment, the hoisting hole 211, the connecting hole 213 and the support rod 100 are respectively located at the ends of the limit plate 210, and the axis of the hoisting hole 211 is located on the center line of the extension direction of the support rod 100. When the hoisting equipment is connected to the limit plate 210, the hoisting equipment applies force to the two limit plates 210. The limit plate 210 decomposes the pulling force of the hoisting equipment into a lateral extrusion force and a vertical pulling force. The extrusion forces on the limit plates 210 at both ends of the support rod 100 are opposite, so that the support rod 100 is only subjected to a lateral pressure load. Thereby improving the load-bearing performance and service life of the loading and unloading tools, and improving the stability and reliability of the hoisting equipment during the hoisting of storage and transportation containers.

[0049] In some embodiments, the hoisting hole 211, the connection hole 213 and the support rod 100 are respectively located at the three ends of the limit plate 210, and the hanging part is located on the center line of the horizontal extension of the support rod 100, so that after the suspension device 300 and the storage platform are limited, it is convenient for the limit plate 210 to bear the weight of the storage container. The support rod 100 is not affected by the bending load, effectively improving the supporting performance of the loading and unloading tool, and ensuring the safety and reliability of the storage container when hanging.

[0050] In some embodiments, in a projection plane perpendicular to the axis of the lifting hole 211, the distance from the edge of the limit plate 210 to the inner wall of the lifting hole 211 is longer, and the distance from the edge of the limit plate 210 to the inner wall of the connecting hole 213 is longer, thereby improving the structural strength of the limit plate 210 at the lifting hole 211 and the connecting hole 213, thereby improving the bearing capacity of the limit member 200.

[0051] In this embodiment, the hanging portion includes a hanging hole 212 formed on the limiting plate 210. The hanging device 300 is connected to the limiting plate 210 through the hanging hole 212.

[0052] The axis of the hoisting hole 211, the axis of the hanging hole 212 and the axis of the connecting hole 213 are coplanar, so as to facilitate the decomposition and offset of the vertical pulling force of the limiting plate 210 when the loading and unloading tool is used.

[0053] The hanging hole 212 is located between the hoisting hole 211 and the connecting hole 213. The hanging device 300 includes a hanging tube 310, which is detachably inserted into the hanging hole 212. The hanging tube 310 is used to limit the limit plate 210 in the storage platform. The position of the hanging hole 212 can prevent the hoisting equipment and the hanging tube 310 from interfering with each other, thereby improving the safety and reliability of the connection between the loading and unloading tool and the hoisting equipment.

[0054] When the types and volumes of storage and transportation containers are different, different types of suspension tubes 310 and limit plates 210 can be replaced, so that after the suspension tube 310 passes through the suspension hole 212, the suspension tube 310 can limit the limit plate 210 in the storage platform, thereby expanding the application range of loading and unloading tools, improving loading and unloading efficiency, and reducing the cost of lifting storage and transportation containers.

[0055] In some embodiments, in the arrangement direction of the hoisting holes 211 and the connecting holes 213, the hanging hole 212 is located at the center of the hoisting holes 211 to the connecting holes 213. The distance from the axis of the hanging hole 212 to the axis of the hoisting hole 211 is equal to the distance from the axis of the hanging hole 212 to the axis of the connecting hole 213. When the loading and unloading tool is suspended, the gravity of the storage and transportation container is transmitted to the limit plate 210 and then directly transmitted to the storage platform through the suspension device 300, reducing the impact on the support rod 100, thereby effectively improving the structural strength and load-bearing capacity of the loading and unloading tool.

[0056] The diameter of the hanging hole 212 is larger than the diameter of the connecting hole 213 and the diameter of the hoisting hole 211. After the hanging tube 310 and the storage platform are limited, the hanging tube 310 supports the limiting plate 210, thereby improving the structural strength and bearing performance of the limiting plate 210 and the hanging tube 310.

[0057] In some embodiments, in a projection plane perpendicular to the axis of the suspension hole 212, the distance from the edge of the limit plate 210 to the inner wall of the suspension hole 212 is greater than the distance from the edge of the limit plate 210 to the inner wall of the lifting hole 211 or the inner wall of the connecting hole 213, thereby ensuring the structural strength of the limit plate 210 at the suspension hole 212 and improving the connection strength and load-bearing capacity of the limit plate 210 and the suspension device 300.

[0058] In this embodiment, the hoisting hole 211, the hanging portion and the connecting hole 213 are arranged in sequence in a projection plane perpendicular to the extension direction of the support rod 100. The plane where the axis of the hoisting hole 211 and the axis of the connecting hole 213 are located passes through the hanging portion.

[0059] When the connection hole 213 is connected to the storage and transportation container, the gravity of the storage and transportation container is transmitted to the limit plate 210. Because the axis of the hoisting hole 211, the hanging part, and the axis of the connection hole 213 are located on the same plane, it can effectively reduce the bending load borne by the limit plate 210, so that the limit plate 210 is only subjected to the tensile load in the vertical direction. During the hoisting and hanging process of the loading and unloading tool, the limit plate 210 can apply a stable pulling force to the storage and transportation container to ensure the stability of the loading and unloading tool during the hoisting and hanging process.

[0060] In some embodiments, the axis of the lifting hole 211, the axis of the hanging hole 212 and the axis of the connecting hole 213 are located on the same vertical plane, so as to facilitate the decomposition and offset of gravity and tension on the loading and unloading tools during lifting and hanging, thereby reducing the stress on the loading and unloading tools.

[0061] In some embodiments, the suspension tube 310 and the limiting plate 210 are detachably connected by threaded connection, snap connection, or riveting. In other embodiments, the suspension tube 310 and the limiting plate 210 are integrally formed.

[0062] In some embodiments, the suspension portion further includes a suspension protrusion (not shown in the figure), the suspension protrusion extends laterally away from the support rod 100, and the suspension protrusion laterally exceeds the edge of the limiting plate 210. When the loading and unloading tool moves into the storage platform, the suspension protrusion is limited by the storage platform to limit the loading and unloading tool and the storage container in the storage platform, so that the storage container is suspended in the storage platform.

[0063] In other embodiments, the hanging protrusion extends longitudinally to limit the position of the storage platform.

[0064] In other embodiments, the suspension device 300 is connected to the suspension protrusion to limit the limiting plate 210 on the storage platform.

[0065] In the related art, a storage rack (not shown in the figure) is provided on the storage platform, and the storage rack is used to limit the position of the suspension device 300 so that the storage and transportation container can be suspended on the storage rack.

[0066] In this embodiment, the limiting member 200 further includes a connecting plate 220 and a reinforcing rib 230. The connecting plate 220 extends in a plane perpendicular to the support rod 100. The support rod 100 and the limiting plate 210 are respectively connected to the two side walls of the connecting plate 220. The connecting plate 220 can improve the connection strength between the support rod 100 and the limiting plate 210.

[0067] In some embodiments, in a plane perpendicular to the extension direction of the support rod 100, the projection of the connecting plate 220 is larger than the projection of the support rod 100. The cross-sectional projection of the connection between the limiting plate 210 and the connecting plate 220 is smaller than the projection of the connecting plate 220. The connecting plate 220 can improve the connection strength between the limiting plate 210 and the support rod 100, and improve the load-bearing capacity of the loading and unloading tool.

[0068] The limiting plate 210 is welded to the connecting plate 220 to improve the connection strength between the limiting plate 210 and the connecting plate 220 .

[0069] In some embodiments, one end of the connecting plate 220 facing the supporting rod 100 is detachably connected to the supporting rod 100. The connecting plate 220 is connected to the supporting rod 100 by threaded connection, snap connection or riveting.

[0070] In other embodiments, the limiting plate 210 is connected to the end of the support rod 100 by welding.

[0071] In this embodiment, the reinforcing ribs 230 are arranged around the limiting plate 210, and the reinforcing ribs 230 extend along the extension direction of the support rod 100 to connect to the connecting plate 220. The reinforcing ribs 230 can effectively improve the structural strength of the limiting plate 210 and the connection strength between the limiting plate 210 and the connecting plate 220.

[0072] In some embodiments, the reinforcing ribs 230 are longitudinally disposed on both sides of the limiting plate 210 to improve the connection strength between the limiting plate 210 and the connecting plate 220. In some embodiments, in a plane perpendicular to the longitudinal direction, the hoisting holes 211, the reinforcing ribs 230 and the axis of the supporting rod 100 along the transverse direction are located in the same plane, thereby improving the structural strength and load-bearing capacity of the loading and unloading tool.

[0073] In some embodiments, the reinforcing rib 230 and the connecting plate 220 are integrally formed.

[0074] In this embodiment, the loading and unloading tool also includes a connecting member 400, which extends along the arrangement direction of the lifting holes 211 and the connecting holes 213. The upper end of the connecting member 400 can be rotatably connected in the connecting hole 213, and the lower end of the connecting member 400 is used to carry the storage and transportation container.

[0075] When the storage and transportation container is connected to the connecting piece 400, the loading and unloading tool can lift the storage and transportation container. During the lifting and hanging process of the loading and unloading tool and the storage and transportation container, the connecting piece 400 can rotate relative to the limit plate 210, thereby reducing the swing amplitude of the storage and transportation container during the movement and hanging process, ensuring the safety of the storage and transportation container during the movement and hanging process, and improving the reliability of the loading and unloading tool.

[0076] In this embodiment, the connecting member 400 includes two rotating plates 410, a first rotating shaft 430, two clamping plates 420 and a second rotating shaft 440. The two rotating plates 410 are respectively located on both sides of the limiting member 200. The first rotating shaft 430 passes through the two rotating plates 410 and the connecting hole 213 so that the rotating plates 410 can rotate around the axis of the first rotating shaft 430 relative to the limiting member 200; the two clamping plates 420 are arranged at intervals, and the two clamping plates 420 extend along the spacing direction of the two rotating plates 410. The upper ends of the two clamping plates 420 are respectively connected to the two rotating plates 410. The second rotating shaft 440 passes through the lower ends of the two clamping plates 420. The two clamping plates 420 and the second rotating shaft 440 are used to limit the storage and transportation containers.

[0077] During the lifting and hanging process of the storage and transportation container, the first rotating shaft 430 and the second rotating shaft 440 are arranged so that the storage and transportation container can rotate around the rotation axis of the first rotating shaft 430 and the rotation axis of the second rotating shaft 440. This can effectively reduce the swing amplitude of the storage and transportation container during the lifting and hanging process, and improve the safety and reliability of the storage and transportation container during transportation.

[0079] In some embodiments, the connecting member 400 includes two rotating plates 410, a first rotating shaft 430, two clamping plates 420 and a fixed tube 450. The two rotating plates 410 are respectively located on both sides of the limiting member 200. The first rotating shaft 430 passes through the two rotating plates 410 and the connecting hole 213, so that the rotating plates 410 can rotate relative to the limiting member 200 around the axis of the first rotating shaft 430. The two clamping plates 420 are arranged at intervals, and the two clamping plates 420 extend along the interval direction of the two rotating plates 410. The upper ends of the two clamping plates 420 are respectively connected to the two rotating plates 410. The fixed tube 450 passes through the lower ends of the two clamping plates 420. The two clamping plates 420 and the fixed tube 450 are used to limit the storage and transportation container.

[0080] In other embodiments, the fixing tube 450 extends along the arrangement direction of the two clamping plates 420, the fixing tube 450 is detachably installed on the two clamping plates 420, and a stop pin 451 is installed at the end of the fixing tube 450. The stop pin 451 extends in a direction perpendicular to the extension direction of the fixing tube 450, and the end of the stop pin 451 can abut against the side wall of the clamping plate 420 to limit the fixing tube 450 on the clamping plate 420.

[0082] In other embodiments, the connecting member 400 includes two rotating plates 410, a first rotating shaft 430 and a second rotating shaft 440. The two rotating plates 410 are arranged at intervals, and the two rotating plates 410 are respectively located on both sides of the limiting plate 210. The rotation axes of the first rotating shaft 430 and the second rotating shaft 440 are arranged in parallel, and the first rotating shaft 430 and the second rotating shaft 440 are respectively penetrated at both ends of the two rotating plates 410 to limit the two rotating plates 410. The first rotating shaft 430 is also penetrated in the connecting hole 213, so that the connecting member 400 can be rotatably limited on the limiting plate 210 through the first rotating shaft 430. The two rotating plates 410 and the second rotating shaft 440 can also be used to connect and limit the storage and transportation containers.

[0083] See also Figures 1 to 8 The utility model provides a loading and unloading tool for a radioactive material storage and transportation container. When the storage and transportation container needs to be transported, the hanging tube 310 is confined in the hanging hole 212, and the loading and unloading tool is moved to the storage place of the storage and transportation container through the lifting equipment, and connected to the storage and transportation container through the connecting piece 400 on the loading and unloading tool.

[0084] When the lifting device is connected to the lifting hole 211 of the limiting plate 210, the lifting device can effectively bear the tension applied by the storage container to the limiting plate 210. At the same time, when the storage container begins to be transported, the storage container can rotate around the rotation axis of the first rotating shaft 430 and the second rotating shaft 440, thereby reducing the swing amplitude of the storage container during suspension. The setting of the support rod 100 can make the limiting plate 210 only subject to the vertical pressure load after the tension of the lifting device and the storage container is decomposed, thereby further ensuring the reliability and stability of the loading and unloading tool.

[0085] Afterwards, the loading and unloading tool and the storage container are hoisted to the storage platform together by the hoisting equipment. When the loading and unloading tool and the storage container are moved to the storage platform, the suspension tube 310 is limited with the storage platform to support the support rod 100, the limit plate 210, the connecting piece 400 and the storage container. The suspension tube 310 can effectively bear the tension applied by the storage container to the limit plate 210, so that the limit plate 210 is only subjected to the vertical pressure load, thereby further ensuring the reliability and stability of the loading and unloading tool.

[0086] When the storage and transportation container needs to be transferred, first connect the suspension device to the suspension part, and then load the storage and transportation container through the connection hole 213 on the loading and unloading tool, so that the loading and unloading tool can drive the storage and transportation container to move. After the loading and unloading tool carries the storage and transportation container, the loading and unloading tool and the storage and transportation container are lifted to the storage platform by the lifting equipment. When the loading and unloading tool moves to the storage platform, the loading and unloading tool is limited on the storage platform by the suspension device 300, so that the storage and transportation container is suspended and stored in the storage platform. The storage and transportation container suspended and stored on the storage platform can be quickly and stably moved to the transport vehicle. Finally, it is transported to the destination and used in nuclear power equipment. The loading and unloading tool can realize the lifting of the storage and transportation container, and can also make the storage and transportation container hang on the storage platform, so as to facilitate the rapid transportation of the storage and transportation container, simplify the transfer process, and effectively improve the transfer efficiency.
