The inner diameter of the platform support ring 220 is greater than the outer diameter of the outer cylinder of the heat pipe stack to be installed, and is used to provide a first working space for installing the outer cylinder. The plurality of detachable support rods 230 are disposed on the platform support ring 220 and extend radially inwards along the platform support ring 220. The plurality of pedals 240 are disposed on the detachable support rods 230 and enclose a ring structure located inside the platform support ring 220. The inner diameter of the ring structure is greater 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 an upright state for vertical installation of the heat pipe stack, which can ensure uniform gaps between the fuel assemblies 20, so as to ensure that the ends of the fuel assemblies 20 are simultaneously inserted into the hexagonal holes of the right support plate (which is above in the vertical installation state, that is, the end of the core assembly 10 away from the core support ring 120). And the tooling operation platform 200 is provided with detachable support rods 230 and pedals 240. When the detachable support rods 230 and the pedals 240 are installed on the platform support ring 220, the inner diameter of the ring structure formed by enclosing the pedals 240 is greater than the inner diameter of the core assembly 10, thereby providing a second working space. Workers can install the core assembly 10 and install the measuring points on the side wall of the core assembly 10 in the second working space; when the detachable support rods 230 and the pedals 240 are not installed on the platform support ring 220, the inner diameter of the platform support ring 220 is greater than the outer diameter of the outer cylinder to be installed, thereby providing a first working space. Workers can install the outer cylinder in the first working space. The tooling platform for vertical installation of the heat pipe stack provided in this embodiment has an adjustable internal working space, which provides convenience for working conditions with multiple working positions and complex construction conditions.

[0047] In some embodiments, the tooling platform for vertical installation of the heat pipe stack includes: four first support legs 110 are evenly distributed below the core support ring 120, and two rib plates 130 are fixedly connected between adjacent two of the first support legs 110. The arrangement of the four first support legs 110 evenly distributed can improve the bearing capacity of the core support assembly 100, and the arrangement of the two rib plates 130 fixedly connected between adjacent two of the first support rods 110 can improve the structural strength of the core support assembly 100.

[0048] In some embodiments, the core support ring 120 is used to bear the left support plate of the core assembly 10 (in the vertically installed state, the left support plate of the core assembly 10 is in contact with the core support ring 120). The core support assembly 100 further includes an intermediate support leg 140, which is arranged at the middle position below the core support ring 120 and is used to prevent the left support plate from being deformed due to excessive load.

[0050] An escalator 260, which is arranged 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 basic ground of the deep pit work station. The escalator 260 is used for operators to enter the first working space and the second working space.

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

[0053] In some embodiments, the height of the first support leg 110 is 1.5 - 2.5 meters. In the vertically installed state, the total height of the product to be installed in place is 6.1 m. Considering that there is a measuring point lead wire about 5 m long at the tail of the core assembly 10, it is optimal to support and raise the core assembly 10 by 2 m to facilitate the arrangement of the measuring point lead wire at the tail of the core assembly 10.

[0054] In some embodiments, a through hole 221 radially penetrating the platform support ring 220 is formed on the side wall of the platform support ring 220, and the detachable support rod 230 can be installed on the platform support ring 220 through the through hole 221; the pedal 240 is of a sector ring structure, and mounting plates 241 fitting the detachable support rod 230 are arranged on both sides of the sector 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 through hole 221 for installing the detachable support rod 230, and the pedal 240 of the sector ring structure is provided, so that the pedal 240 can be directly laid on the detachable support rod 230, improving the installation and disassembly convenience of the overall tooling platform.

[0055] In some embodiments, the tooling operation platform 200 includes eight second support legs 210, and the eight second support legs 210 are evenly distributed on the outer edge of the platform support ring 220. The eight second support legs 220 are provided to improve the bearing capacity of the platform support ring 220, so as to facilitate the simultaneous operation of multiple staff members.

[0056] In some embodiments, the working operation 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 exchange components of the heat pipe stack. Since the heat exchange components and the core assembly 10 have different heights in the erected state, setting two platform support rings 220 with different heights can provide the third working space for installing the heat exchange components and the measuring points on the outer sidewall of the heat exchange components.

[0057] In summary, the tooling platform for vertical installation of the heat pipe stack provided in this embodiment has a simple structure and is convenient for assembly; on the premise of ensuring the structural strength of the tooling, it reduces weight as much as possible, facilitating on-site construction and operation; within a limited space, it meets the working requirements of on-site workers; through a simple support structure, it realizes the function of adjustable working positions, can ensure uniform gaps between the fuel assemblies 10 in the vertical installation state, and through the detachable support rods 230 and pedals 240, it can adjust the internal space, and can be used not only for installing the core assembly 10, heat exchange components, measuring points on the sidewall of the core assembly 10 and measuring points of the heat exchange components, but also for installing the outer cylinder assembly.
