[0002] During the manufacturing process of the new reactor type overall performance test reactor vessel (heat pipe reactor), the assembly precision requirements for its internal components—the core assembly and heat exchange assembly—are extremely high. Thousands of thermocouple measuring points are arranged on the front and rear end faces, heating sections, and cooling sections of components such as the core assembly, heat exchange assembly, and heat pipes to collect data. This data is then compared and verified with theoretical calculations and actual operational analysis data to ensure the product's feasibility. The heat pipe reactor is a horizontal device; however, due to its complex internal structure, please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a schematic diagram of the installation of a single fuel assembly. The entire assembly consists of thirty fuel assemblies 20.

[0042] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the tooling platform and its usage method for vertical mounting of heat pipe stacks proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the embodiments of this invention. Please refer to the drawings to make the objectives, features, and advantages of this invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this invention, should still fall within the scope of the technical content disclosed in this invention.

[0043] Please see Figures 1-9 The tooling platform for vertical mounting of heat pipe stacks provided in this embodiment includes:

[0044] The core support assembly 100 includes a plurality of first support legs 110 and a core support ring 120 disposed above the plurality of first support legs 110, the core support ring 120 being used to support the core assembly 10 in an upright state.

[0045] The tooling operation platform 200 includes multiple second support legs 210, at least one platform support ring 220 disposed on the multiple second support legs 210, multiple detachable support rods 230, and multiple pedals 240. The inner diameter of the platform support ring 220 is larger than the outer diameter of the outer shell of the heat pipe stack to be installed, and is used to provide a first working space for installing the outer shell. The multiple detachable support rods 230 are disposed on the platform support ring 220 and extend radially inward along the platform support ring 220. The multiple pedals 240 are disposed on the detachable support rods 230, forming an annular structure located inside the platform support ring 220. The inner diameter of the annular structure is larger than the outer diameter of the core assembly 10, and is used to provide a second working space.

[0046] In the above embodiment, a core support ring 220 is provided to support the core assembly 10 in the vertical state for vertical mounting of the heat pipe stack. This ensures that the gaps between the fuel assemblies 20 are uniform, thereby ensuring that the ends of each fuel assembly 20 are simultaneously inserted into the hexagonal holes of the right support plate (located at the top in the vertical mounting state, i.e., the end of the core assembly 10 away from the core support ring 120). The tooling platform 200 is equipped with a detachable support rod 230 and a pedal 240. When the detachable support rod 230 and the pedal 240 are installed on the platform support ring 220, the inner diameter of the annular structure formed by the pedal 240 is larger than the inner diameter of the core assembly 10, thus providing a second working space where workers can install the core assembly 10 and the side wall measuring points of the core assembly 10. When the detachable support rod 230 and the pedal 240 are not installed on the platform support ring 220, the inner diameter of the platform support ring 220 is larger than the outer diameter of the outer cylinder to be installed, thus providing a first working space where workers can install the outer cylinder. The tooling platform for vertical installation of heat pipe stacks provided in this embodiment has an adjustable internal working space, providing convenience for multi-station and complex construction conditions.

[0047] In some embodiments, the tooling platform for vertical assembly of heat pipe stacks includes: four first support legs 110 evenly distributed below the core support ring 120, and adjacent first support legs 110 are fixedly connected by two stiffening plates 130. The even distribution of the four first support legs 110 improves the load-bearing capacity of the core support assembly 100, and the fixed connection between adjacent first support legs 110 by two stiffening plates 130 improves the structural strength of the core support assembly 100.

[0048] In some embodiments, the core support ring 120 is used to support the left support plate of the core assembly 10 (in the upright state, the left support plate of the core assembly 10 is in contact with the core support ring 120). The core support assembly 100 also includes an intermediate support leg 140, which is located at the middle position below the core support ring 120 to prevent the left support plate from deforming due to excessive load.

[0049] In some embodiments, the working platform for vertical mounting of heat pipe stacks further includes:

[0050] An escalator 260 is mounted on a second support leg 210 of the tooling platform;

[0051] The core support assembly 100 and the tooling operation platform 200 are placed on the foundation ground of the deep pit work station, and the ladder 260 is used to allow workers to enter the first work space and the second work space.

[0052] In some embodiments, the tooling operation platform 200 further includes a guardrail 250 surrounding the outer edge of the platform support ring 220. The guardrail 250 is positioned at the outer edge of the platform support ring 220 to ensure the safety of workers.

[0053] In some embodiments, the height of the first support leg 110 is 1.5-2.5 meters. In the upright state, the total height of the product to be installed is 6.1m. Considering that there is a measuring point lead wire of about 5m at the tail of the core assembly 10, it is best to support the core assembly 10 at a height of 2m to facilitate the management of the measuring point lead wire at the tail of the core assembly 10.

[0054] In some embodiments, the platform support ring 220 has a through hole 221 that radially penetrates the platform support ring 220. The detachable support rod 230 can pass through the through hole 221 and be installed on the platform support ring 220. The pedal 240 has a fan-ring structure, and mounting plates 241 that fit the detachable support rod 230 are provided on both sides of the fan-ring structure, so that the pedal 240 can be laid on the detachable support rod 230. In this embodiment, the platform support ring 220 is provided with a through hole 221 for installing the detachable support rod 230, and the pedal 240 with a fan-ring structure is provided, so that the pedal 240 can be directly laid on the detachable support rod 230, improving the overall ease of installation and disassembly of the tooling platform.

[0055] In some embodiments, the tooling operating platform 200 includes eight second support legs 210, which are evenly distributed on the outer edge of the platform support ring 220. The eight second support legs 220 are configured to increase the load-bearing capacity of the platform support ring 220, facilitating simultaneous operation by multiple workers.

[0056] In some embodiments, the operating platform includes two platform support rings 220 with different heights, which are respectively used to provide the second working space and the third working space for installing the heat exchanger assembly of the heat pipe stack. Since the heat exchanger assembly and the core assembly 10 have different heights in the upright state, providing two platform support rings 220 with different heights can provide a third working space for installing the heat exchanger assembly and the measuring points on the outer wall of the heat exchanger assembly.

[0057] In summary, the tooling platform for vertical assembly of heat pipe stacks provided in this embodiment has a simple structure and is easy to assemble; it reduces weight as much as possible while ensuring the structural strength of the tooling, making it convenient for on-site construction and operation; it meets the working requirements of on-site workers within a limited space; it achieves adjustable workstation functionality through a simple support structure, ensuring uniform gaps between fuel assemblies 10 in the vertical assembly state; and it can adjust the internal space through detachable support rods 230 and pedals 240, making it suitable for installing core assemblies 10, heat exchange assemblies, sidewall measuring points of core assemblies 10 and heat exchange assembly measuring points, as well as outer shell assemblies.

[0058] This embodiment also provides a method for using the tooling platform for vertical mounting of heat pipe stacks according to any of the above embodiments, including:
