[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] The following is combined with Figures 1-5 The present invention describes a large-size pipe installation device for installing a window pipe 100 into an opening 201 on the outer side wall of a fusion reactor main unit 200. Generally speaking, the fusion reactor main unit 200 has openings 201 of various specifications and shapes along the circumference. The large-size pipe installation device assembles and welds the window pipe 100 to the opening 201.

[0043] like Figure 1 and Figure 2 As shown in the figure, the large-size pipe installation device provided in this embodiment of the present invention includes a measuring device, a transfer frame 1, an adjustment assembly 2, and a hoisting mechanism 3. The measuring device is used to measure the center coordinates of the opening 201. The measuring device can be installed at the center of the fusion reactor host 200 to establish a globally unified measurement benchmark. This provides high-precision target position data for the accurate alignment of the subsequent window pipe 100, ensuring absolute accuracy of the installation from the source and avoiding cumulative errors caused by inconsistent benchmarks or multiple benchmark switching.

[0044] The transfer frame 1 is used to transfer the window pipe 100, ensuring the stability and safety of the window pipe 100 during transportation in complex field environments, and effectively preventing deformation or damage to the precision pipe due to factors such as bumps and vibrations.

[0045] Adjustment component 2 is mounted on transfer frame 1 and is used to adjust the position of window pipe 100 so that the center of the end of window pipe 100 near the opening corresponds to the center coordinate of the opening. Adjustment component 2 can realize fine operation such as translation, lifting, and rotation of pipe, thereby achieving precise alignment of the center of the end of window pipe 100 with the center coordinate of opening 201. This fine adjustment capability is the key to achieving high-precision installation, effectively solving the technical pain point that it is easy to hoist large components into place but difficult to align them accurately, and significantly improving the success rate of docking and installation efficiency.

[0046] The hoisting mechanism 3 is used to hoist the window pipe 100. The hoisting mechanism 3 is typically located on top of the fusion reactor main unit 200, making full use of the existing on-site structure as support. This simplifies the layout and coordination of large external hoisting equipment and enables macroscopic, large-scale vertical displacement of the pipe, creating the preconditions for the subsequent precise adjustment of the adjustment component 2. Preferably, the hoisting mechanism 3 uses an electric hoist.

[0047] like Figure 3 As shown, in a feasible embodiment of the present invention, the adjustment component 2 includes a first adjustment mechanism 21, a second adjustment mechanism 22 and a third adjustment mechanism 23.

[0048] The first adjustment mechanism 21 is slidably mounted on the transfer frame 1 along the first direction. The first adjustment mechanism 21 is used to support the window pipe during the movement process, realizing the linear translation adjustment of the window pipe 100 in one dimension in the horizontal plane. It can accurately correct the positional deviation of the window pipe 100 in the first direction. As the main load-bearing structure, it can also ensure smooth and uninterrupted movement when carrying heavy pipes, providing a stable and reliable foundation for accurate alignment.

[0049] Specifically, a slide rail can usually be installed on the top of the transfer frame 1, and the first adjustment mechanism 21 moves along the slide rail.

[0050] The second adjustment mechanism 22 is slidably mounted on the transfer frame 1 along the second direction. The second adjustment mechanism 22 provides the window pipe 100 with the ability to linearly translate in another dimension in the horizontal plane, and can be used to correct the positional deviation of the window pipe 100 in the second direction.

[0051] The third adjustment mechanism 23 is vertically adjustable on the second adjustment mechanism 22 along the third direction. It is responsible for adjusting the vertical height of the window pipe 100. Through its lifting function, it can accurately compensate for the vertical error generated during hoisting and ensure that the center of the window pipe and the center of the opening are completely consistent in height.

[0052] Among them, the first direction, the second direction, and the third direction are perpendicular to each other in three-dimensional space. It can be understood that the first direction is the direction along the axis of the opening 201, that is, the front and back direction of the opening; the second direction is the left and right direction of the opening; and the third direction is the height direction of the opening.

[0053] like Figure 4 As shown, in a feasible embodiment of the present invention, the first adjustment mechanism 21 includes a first support plate 211 and a first linear motion member 212.

[0054] The first support plate 211 is slidably connected to the top of the transfer frame 1, and the first support plate 211 is used to support the window pipe 100. Through the sliding connection, the window pipe 100 can be adjusted in a wide range of horizontal directions, which can flexibly adapt to different initial installation positions, improve versatility and on-site adaptability. At the same time, the first support plate 211 provides a stable and reliable initial placement platform for the window pipe 100, effectively preventing the risk of tipping or damage caused by unstable support in the early stages of transfer and adjustment, and simplifying the preparation work before hoisting.

[0055] The first linear motion component 212 is mounted on the transfer frame 1 at one end and on the first support plate 211 at the other end. Through automated driving, precise and efficient control of the horizontal position of the window pipe 100 is achieved. Compared to manual movement, this greatly reduces the labor intensity of operators and significantly improves the accuracy and efficiency of positioning.

[0056] The hoisting mechanism 3 is used to hoist the window pipe, so that the center of gravity of the window pipe is transferred from the first support plate 211 to the third adjustment mechanism 23, realizing the separation and connection of coarse adjustment and fine adjustment functions. By transferring the load from the first support plate 211 used for horizontal coarse adjustment to the third adjustment mechanism 23, conditions are created for subsequent multi-dimensional precise adjustment, avoiding motion interference between the adjustment mechanisms, ensuring that the entire installation process is carried out step by step, clearly and controllably, and ultimately improving the installation accuracy and overall operation efficiency of the window pipe.

[0057] In one feasible embodiment of this utility model, the first support plates 211 are arranged in pairs, and the shape of the top of the first support plate 211 is adapted to the window pipe 100. By having two separate support points jointly support the window pipe 100, a more stable and reliable support structure is formed, which can effectively prevent the long window pipe from tipping over or swaying due to an unstable center of gravity. At the same time, the load is distributed more evenly on the transfer frame 1, improving the safety and load-bearing capacity of the overall structure.

[0058] Furthermore, the shape of the top of the first support plate 211 is adapted to the bottom contour of the window pipe 100, which significantly increases the contact area between the support plate and the pipe. This allows for better fixation of the window pipe 100, preventing it from rolling or shifting laterally during horizontal sliding adjustment, and providing self-centering and passive limiting. At the same time, the close contact surface effectively avoids stress concentration damage to the pipe surface, thus protecting the window pipe 100 from scratches or pressure damage and ensuring the integrity of the components.

[0059] like Figure 5 As shown, in a feasible embodiment of this utility model, the second adjustment mechanism 22 includes a connecting plate 221, a second support plate 222, and a second linear motion component 223. The connecting plate 221 is vertically arranged on the transfer frame 1, providing a stable and vertical installation reference and guide rail for the entire second adjustment mechanism 22, ensuring that the subsequent lifting and lowering movements are strictly along the vertical direction, avoiding adjustment errors caused by tilting or swaying, and safely transferring all loads to the main structure of the transfer frame 1.

[0060] The second support plate 222 is slidably connected to the connecting plate 221, forming the core motion structure for realizing movement along the second direction. Through this sliding connection, the second support plate 222 can move up and down along the connecting plate 221, thereby achieving a wide range of adjustments to the vertical height of the window pipe to adapt to the installation requirements of different floors and solving the problem of the window pipe 100 being difficult to vertically position.

[0061] The second linear motion component 223 is mounted on the connecting plate 221 at one end and on the second support plate 222 at the other end. Under the action of the second linear motion component 223, the second support plate 222 slides along the second direction. By using automated components such as electric push rods as the driving force source, the lifting process is automated, labor-saving, and precisely controlled. Compared with manual adjustment, automated drive greatly reduces the labor intensity of workers and improves the safety of the operation process. At the same time, the inherent high-precision stroke control capability of the linear motion component allows operators to make millimeter-level precise fine adjustments to the height of the window pipe, ensuring perfect alignment with the installation position, significantly improving installation quality and efficiency.

[0062] In one feasible embodiment of this utility model, the third adjustment mechanism 23 includes a third linear motion component 231 and a third support plate 232. The third linear motion component 231 is vertically disposed on the second support plate 222; the third support plate 232 is disposed on the third linear motion component 231, and the shape of the top side of the third support plate 232 is adapted to the window pipe 100. The third support plate 232 serves as the final support platform for the window pipe during the fine-tuning stage. When the hoisting mechanism 3 transfers the center of gravity of the pipe, its contact surface (such as a V-groove or arc groove) adapted to the pipe can instantly provide a stable and centered support effect, effectively preventing the pipe from rolling or sliding during the final lifting and fine-tuning process, ensuring the safety and stability of the entire fine-tuning process. Simultaneously, this fitted support method, by increasing the contact area, effectively avoids stress damage to the pipe surface coating or structure caused by point contact or line contact, protecting the integrity of the components during installation.

[0063] More specifically, the first linear motion component 212, the second linear motion component 223, and the third linear motion component 231 can be cylinders, hydraulic cylinders, or other mechanisms that can achieve linear motion, preferably jacks.

[0064] In one feasible embodiment of this utility model, the second adjustment mechanism 22 further includes a guide rod 224, which is disposed between the second support plate 222 and the third support plate 232. The guide rod 224 provides precise guidance for the lifting and fine-tuning movement of the third support plate 232 and effectively prevents rotation, ensuring that the third support plate 232 effectively avoids tilting, shaking, or rotation that may occur due to uneven force when bearing heavy objects, thereby significantly improving the stability and positioning accuracy of the fine-tuning process. The guide rod 224 is arranged parallel to the third linear motion component 231, effectively bearing and offsetting the lateral force and bending moment caused by the offset of the center of gravity of the window pipe 100, so that the third linear motion component 231, as the core driving element, basically only bears axial force.

[0065] In one feasible embodiment of this utility model, a stiffening plate 101 is also included, and the stiffening plate 101 covers the center of the window pipe 100. The center of the window pipe 100 can be marked on the stiffening plate 101, which can effectively enhance the structural rigidity and strength of the window pipe 100 itself, prevent it from bending and deforming due to its own weight or uneven force during transportation and hoisting, thereby ensuring the dimensional accuracy and installation quality of the component.

[0066] In one feasible embodiment of this invention, a tooling platform 4 is also included, disposed around the periphery of the fusion reactor main unit 200. The tooling platform 4 provides a working platform for the transfer frame 1. First, this layout allows the transfer frame 1 to be placed as close as possible to the target installation window, thereby effectively shortening the adjustment stroke and cantilever distance of each adjustment mechanism (especially the horizontal adjustment mechanism), which directly improves the rigidity, stability, and final positioning accuracy of the entire installation system. Second, as an independent support structure, it avoids the transfer equipment and its operating load from directly acting on the precision and sensitive fusion reactor main unit, achieving physical isolation of the core equipment during installation, effectively preventing potential collisions, vibrations, or stress transmission, thereby greatly improving the safety of the entire installation process.

[0067] This utility model embodiment provides an installation method for a large-size pipe installation device, utilizing any of the above-mentioned installation devices, including:

[0068] Scan the outline of the opening 201 of the window pipe 100 to be installed, determine the center of the opening 201, and record the center coordinates;

[0069] Hoist the window pipe 100 to the adjusting component 2, and adjust the position of the window pipe by adjusting the adjusting component 2 so that the center of the window pipe 100 corresponds to the center of the opening 201;

[0070] Spot weld and fix the window pipe 100 and the opening, remove the transfer frame 1, and proceed with the installation of the next area window.

[0071] More specifically, the installation methods include:

[0072] The outline of the opening 201 of the window to be installed is scanned by measuring equipment to determine the center of the opening 201 and the center coordinates are recorded.

[0073] The transfer frame 1 and the adjustment assembly 2 are assembled and fixed using external hoisting equipment.

[0074] The external hoisting mechanism 3 hoists the window pipe 100 between two first support plates 211 and pushes the window pipe 100 to the appropriate position through the first linear motion component 212 below.

[0075] The electric hoist on the main body of the device lifts the window pipe 100 to the front lifting point for protection. The window is manually pushed to place it on the third support plate 232 and the front first support plate 211. The electric hoist is released, the transfer device continues to move, and is assisted by manual pushing to make the window continue to move forward until the center of gravity of the window is on the third support plate 232. The electric hoist changes the lifting point to protect the window.

[0076] The position of the window is adjusted by adjusting the left and right pushing jacks and the main lifting jack of component 2, and the center coordinates of the inner stiffener 101 of the window are monitored in real time by the measuring equipment inside the device until the coordinates match the coordinates in step one.

[0077] The window pipe 100 is spot-welded to the device body for fixation. The adjustment component 2 and the transfer frame are then removed, and the next area of ​​windows is installed. Next, the windows in this area are reinforced by welding. During the welding process, the center coordinates inside the window are continuously monitored, and the welding process is adjusted to ensure that the changes in the center coordinates remain within the allowable range.

[0078] In summary, the large-size pipe installation device provided by this utility model allows for the on-site transfer and adjustment of large-size windows using a transfer frame and adjustment device. Simultaneously, it enables precise positioning and assembly of the window pipes using measuring equipment. Furthermore, it strengthens process monitoring during welding and adjusts the welding process in real time, thereby improving the final accuracy of the window and meeting the high-precision assembly and manufacturing requirements of fusion reactor devices.
