[0002] Nuclear raw materials refer to materials used in nuclear technology applications such as nuclear power generation or nuclear weapons manufacturing. There are some abundant nuclear raw materials in nature, which are important energy resources that humans can use. Uranium ore is one of the most important nuclear raw materials. It is an ore containing uranium in nature. Uranium ore mainly exists in granite, biotite schist and sandstone in the earth's crust. The areas with high enrichment levels include Australia, Canada, Kazakhstan and other countries. These nuclear raw materials are important energy resources that humans can use, and are of great significance for nuclear technology applications such as nuclear power generation and nuclear weapons manufacturing.

[0003] The transportation of such flammable and explosive chemical raw materials or nuclear raw materials containing radioactive substances has always been a very dangerous task. At present, most nuclear containers are transported by train. After the train arrives at the station, the lifting personnel cooperate with the crane to load and unload the containers, which involves a high risk of lifting operations. In addition, in areas where there is no train transportation, if a new train transportation line is built for this special container, the construction period will be long and the capital investment will be large. Moreover, these nuclear containers still require manpower for loading and unloading, which involves a high risk of radioactive material leakage and occupational health, posing a threat to the safety and health of employees. Summary of the invention

[0006] Furthermore, the connecting assembly includes a T-rod, a bolt guide sleeve, a hexagon socket bolt, a spring washer, and a flat washer; the spring washer is arranged in the bolt guide sleeve, and the flat washer is arranged below the bolt guide sleeve. After the lower end of the hexagon socket bolt extends out of the spring washer and the bolt guide sleeve, it passes through the flat washer, and the lower end of the T-rod is inserted into the bolt guide sleeve and matches the groove on the top of the hexagon socket bolt; connecting holes are also arranged on the two ears of the bolt guide sleeve.

[0007] Furthermore, a sliding groove for a spring washer is provided on the inner wall of the lower end of the bolt guide sleeve.

[0008] Furthermore, a positioning triangle mark is provided above the lifting connection piece.

[0030] Example 1

[0031] In order to solve the problem of personnel health risks caused by the need for manual loading and unloading of existing high-risk chemical raw material storage tanks, the purpose of the present invention is to provide an automatic loading and unloading auxiliary structure for high-risk chemical raw material transport storage tanks. The automatic loading and unloading auxiliary structure for high-risk chemical raw material transport storage tanks can cooperate with the automatic loading and unloading system to realize the automatic loading and unloading of storage tanks for high-risk chemical raw materials or nuclear materials containing radioactive substances.

[0032] This embodiment first describes the structure of the high-risk chemical raw material transportation and storage tank. Figure 8 As shown, the high-risk chemical raw material transportation and storage tank includes an outer tank body 6, an outer tank body top cover 7 arranged above the outer tank body 6, an inner tank body 8 is arranged inside the outer tank body 6 as an inner container, and the outer tank body 6 is a shielding container. The inner tank body 8 and the outer tank body 6 are used together to improve the safety of transportation of dangerous chemical raw materials or nuclear raw materials.

[0033] In order to facilitate automatic loading and unloading operations, such as Figure 8 to Figure 12 As shown, an automatic loading and unloading auxiliary structure for high-risk chemical raw material transportation and storage tanks is arranged above the outer tank body top cover 7; a lifting lug is arranged on the side wall of the inner tank body 8; and a structure for the lifting lug of the inner tank body 8 is arranged inside the outer tank body 6, which will be described in detail one by one below.

[0034] This embodiment provides a Figure 1 to Figure 7 The automatic loading and unloading auxiliary structure of the high-risk chemical raw material transportation and storage tank shown in the figure includes a ring plate 1 and a lifting connection piece 2. A plurality of mounting holes 3 are arranged at equal intervals on the ring plate 1. Connecting holes 5 are arranged on both sides of the mounting holes 3. A connecting component 4 is arranged in the mounting hole 3, and the connecting component 4 is fixed through the connecting hole 5. The lifting connection piece 2 includes a main body 2-1 of the lifting connection piece, four connecting ears 2-2 symmetrically arranged on the side of the main body 2-1, and two lifting ears 2-3 symmetrically arranged on the side of the main body 2-1. The automatic loading and unloading auxiliary structure of the high-risk chemical raw material transportation and storage tank has two functions: one is to fix the outer tank body 6 and the outer tank body top cover 7 through the connecting component 4, and the other is to fix the outer tank body top cover 7 through the lifting connection piece 2, so as to improve the efficiency of automatic loading and unloading of high-risk chemical raw materials or nuclear materials and avoid the trouble of replacing the lifting components of the lifting system.

[0035] Further, the connecting assembly 4 includes a T-bar 4-1, a bolt guide sleeve 4-2, a hexagon socket bolt 4-3, a spring washer 4-4, and a flat washer 4-5; the spring washer 4-4 is arranged in the bolt guide sleeve 4-2, and the flat washer 4-5 is arranged below the bolt guide sleeve 4-2. After the lower end of the hexagon socket bolt 4-3 extends out of the spring washer 4-4 and the bolt guide sleeve 4-2, it passes through the flat washer 4-5, and the lower end of the T-bar 4-1 is inserted into the bolt guide sleeve 4-2 and matches the groove at the top of the hexagon socket bolt 4-3; the two ears of the bolt guide sleeve 4-2 are also provided with There is a connecting hole 4-6; the function of the connecting component 4 is to fix the outer tank top cover 7 and the outer tank body 6; in order to facilitate the automatic loading and unloading operation of the hexagon socket bolt 4-3, a T-bar 4-1 is arranged above it, and the lower end of the T-bar 4-1 coincides with the hexagon socket bolt 4-3. The difficulty of positioning the T-bar 4-1 by removing and installing the screws of the automatic loading and unloading system is much less than directly positioning the hexagon socket bolt 4-3. Therefore, the setting in the connecting component 4-4 can reduce the difficulty of automatic loading and unloading of the hexagon socket bolt 4-3 and improve the efficiency of automatic loading and unloading.

[0036] Furthermore, a sliding groove 4-7 of a spring washer 4-4 is provided on the inner wall of the lower end of the bolt guide sleeve 4-2; the spring washer 4-4 cooperates with the flat washer 4-5, which can, on the one hand, reduce the direct force applied by the hexagon socket bolt 4-3 to the connecting hole 7-4 of the mounting mechanism, and on the other hand, limit the hexagon socket bolt 4-3 so that the hexagon socket bolt 4-3 will not fall directly out of the ring plate 1.

[0037] Furthermore, a positioning triangle mark is provided above the lifting connector 2. The positioning triangle mark is made of steel and has a right triangle shape, wherein an acute angle of the positioning triangle mark is located at the center of the lifting connector 2, and the two right-angled sides of the positioning triangle mark correspond to a connecting component 4 respectively. The auxiliary positioning camera of the automatic loading and unloading system of the storage tank can perform image recognition on the three corners of the positioning triangle mark, first locate the center of the lifting connector 2, and then locate the connecting components 4 corresponding to the two right-angled sides by identifying the two right-angled sides. Since the connecting components 4 are arranged at equal intervals on the ring plate 1 and the number is 12, the angle between two adjacent connecting components 4 is fixed at 30°. The bolt tightening device of the automatic loading and unloading system of the storage tank takes the center of the lifting connector 2 as the center of the circle and rotates 30° successively to position the 12 connecting components 4 successively.

[0038] The connection assembly 4 plays a very important role in the disassembly process. The automatic loading and unloading system of the storage tank designed on the high-risk chemical raw material transport vehicle needs to automatically load and unload the inner tank body 8 and automatically disassemble the outer tank body top cover 7. During the automatic disassembly process of the outer tank body top cover 7, the positioning of the hexagon socket bolt 4-3 is particularly important. However, although the above-mentioned positioning triangle mark realizes the position positioning of the connecting component 4, it still cannot accurately connect the bolt tightening device of the automatic loading and unloading system of the storage tank with the hexagonal bolt 4-3. In order to accurately connect the bolt tightening device of the automatic loading and unloading system of the storage tank with the hexagonal bolt 4-3 and reduce the difficulty of automatic disassembly, the connecting component 4 is provided with a bolt guide sleeve 4-2. On the one hand, the bolt guide sleeve 4-2 can restrict the hexagonal bolt 4-3, so that the hexagonal bolt 4-3 is in the bolt guide sleeve 4-2 whether it is in a connected state or a separated state, and will not fall directly. At the same time, the T-bar 4-1 arranged above the hexagonal bolt 4-3 is also always in the bolt guide sleeve 4-2, and the lower end of the T-bar 4-1 is consistent with the nut of the hexagonal bolt 4-3, and the upper end of the T-bar 4-1 is higher than the nut Bolt guide sleeve 4-2, when the automatic loading and unloading system of the storage tank designed on the high-risk chemical raw material transport vehicle needs to automatically tighten or loosen the hexagon socket bolt 4-3, there is no need to directly align the hexagon socket bolt 4-3, only the bolt tightening device of the automatic loading and unloading system of the storage tank designed on the high-risk chemical raw material transport vehicle needs to be used to position the upper end of the T-bar 4-1. It only needs to be positioned to the upper end of the T-bar 4-1. After the wrench of the bolt tightening device contacts the upper end of the T-bar 4-1, it maintains downward pressure and rotates slowly, and it will combine with the T-bar 4-1. Continuing to rotate can complete the tightening or loosening operation of the hexagon socket bolt 4-3, and there is no need to accurately position the nut of the hexagon socket bolt 4-3, which can greatly reduce the difficulty of positioning the hexagon socket bolt 4-3 and improve the efficiency of automatic loading and unloading; Fig.13Shown is a schematic diagram of a wrench for the bolt tightening device of the automatic loading and unloading system for the transport and storage tanks of highly dangerous chemical raw materials.

[0039] Further, such as Fig. 9 As shown, the outer tank body top cover 7 includes a top cover body 7-2, a lifting plate 7-1 is arranged on the top cover body 7-2, a lifting hole 7-3 is arranged on the lifting plate 7-1, and the top cover body 7-2 is also provided with a mounting mechanism connecting hole 7-4; the lifting hole 7-3 arranged on the lifting plate 7-1 can actually be directly lifted, but the lifting assembly needs to be redesigned. In order to make the lifting of the automatic loading and unloading auxiliary structure of the high-risk chemical raw material transportation and storage tank more convenient, a lifting connector 2 is arranged above the outer tank body top cover 7, and the lifting ear 4-23 of the lifting connector 2 is exactly the same as the mounting lifting ear 8-2 on the side of the inner tank body 8 described below, and the same lifting plate can be used for lifting, which can greatly improve the convenience and versatility of the automatic loading and unloading of the automatic loading and unloading auxiliary structure of the high-risk chemical raw material transportation and storage tank.

[0040] Further, such as Fig.11 As shown, the outer tank body 6 includes an outer tank body main body 6-1, and an installation limit plate 6-2 is arranged above the outer tank body main body 6-1. Four installation limit plates 6-2 are symmetrically arranged to assist in positioning, so that the outer tank body top cover 7 can be smoothly and quickly installed on the outer tank body 6; an outer tank body top cover connecting hole 6-3 is also arranged above the outer tank body main body 6-1, and the positions of the outer tank body top cover connecting hole 6-3, the mounting hole 3 on the ring plate 1, and the mounting mechanism connecting hole 7-4 correspond to each other, so as to ensure that the hexagon socket bolt 4-3 of the connecting assembly 4 can fix the outer tank body 6 and the outer tank body top cover 7; an inner tank body limit seat 6-4 is arranged in the outer tank body main body 6-1.

[0041] Further, such as Fig.10 As shown, the inner tank body 8 includes an inner tank body main body 8-1, and the inner tank body main body 8-1 has two groups of mounting ears 8-2 symmetrically on the upper side; a stop block 8-3 is arranged on any one of the two groups of mounting ears 8-2; the installation positions of the two groups of mounting ears 8-2 correspond to the inner tank body limit seats 6-4 arranged in the outer tank body main body 6-1, and a stop block 8-3 is arranged on one of the groups of mounting ears 8-2; in this way, the stop block 8-3 can be used to stop the inner tank body 8 The lifting lugs 8-2 are limited in position to prevent displacement of the lifting lugs 8-2 during transportation, which may cause the lifting lugs 8-2 to contact the inner tank limit seat 6-4, making it impossible for the lifting plate of the automatic loading and unloading system of the storage tank to hook the lifting lugs smoothly, thus affecting the automatic loading and unloading of the automatic loading and unloading auxiliary structure of the storage tank for transporting high-risk chemical raw materials. This is also the reason why two groups of lifting lugs 8-2 are provided, one group with a stop block 8-3 is used for limiting, and the other group without a stop block 8-3 is used for lifting. The two groups can be used interchangeably.

[0042] In summary, the automatic loading and unloading auxiliary structure of the high-risk chemical raw material transportation storage tank is a special storage tank. An automatic loading and unloading system for the storage tank is designed on the high-risk chemical raw material transportation vehicle. The automatic loading and unloading system for the storage tank is provided with a hanging plate, which can cooperate with the hanging ears 7-3 on the outer tank top cover 7 and the mounting hanging ears 8-2 on the side of the inner tank 8, so as to lift the outer tank top cover 7 or the inner tank 8; on the other hand, the connection component 4 of the auxiliary mounting mechanism 4 can be automatically disassembled through the automatic loading and unloading system of the storage tank, so as to realize the automatic disassembly and assembly of the outer tank top cover 7 and the outer tank 3, so that The loading and unloading of storage tanks can be completely automatic, getting rid of manual operation, reducing the contact between workers and high-risk chemical raw materials or nuclear materials, and reducing the threat of high-risk chemical raw materials or nuclear materials to the safety and health of employees; in addition, the automatic loading and unloading system for nuclear containers using the automatic loading and unloading auxiliary structure of the high-risk chemical raw material transport storage tank is an automatic loading and unloading system that can be set in the container of the transport vehicle, thus breaking the limitation that nuclear containers can only be transported by train, especially in areas where train transportation is not available, there is no need to build new train transportation lines, which can save a lot of capital investment.

[0043] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
