Description

Technical Field

[0001] The present invention relates to the technical field of nuclear fusion devices, and in particular to a hoisting mechanism and a hoisting method for a vacuum chamber sector. Background Art

[0002] Nuclear fusion reaction is a process in which light atomic nuclei (such as hydrogen isotopes deuterium and tritium) are combined to form heavier atomic nuclei (such as helium) and release huge amounts of energy. It is of great significance to the fields of energy, science and technology, and the environment in human society, and is regarded as one of the ultimate solutions to the global energy crisis.

[0003] Among them, the vacuum chamber in the nuclear fusion device is a key component. The vacuum chamber is usually composed of multiple sectors, which need to be hoisted during the manufacturing, transportation and installation processes.

[0004] In the prior art, there are generally two ways to suspend a vacuum chamber: one is to suspend the vacuum chamber sector with a single suspending ear, and the other is to suspend the entire vacuum chamber with a ring array structure. When a single suspending ear structure is used to suspend the vacuum chamber sector, the single suspending ear structure may not be able to withstand the large size and high weight of the vacuum chamber sector of a nuclear fusion device, and will cause stress concentration at key locations (such as the connection between the suspending ear and the vacuum chamber sector), resulting in local fatigue damage and affecting the service life of the vacuum chamber sector. At the same time, the existing single suspending ear structure cannot adjust the position and posture of the vacuum chamber sector, so when the vacuum chamber sector is suspended, the suspending ear structure may not be able to suspend the vacuum chamber sector. When the center of gravity of the chamber sector deviates, there is a risk of the vacuum chamber sector shaking, tilting or colliding during the lifting process, causing damage to the equipment or creating a safety hazard for personnel, affecting the safety of the lifting; when the annular array structure is used to lift the entire vacuum chamber, due to the heavy weight of the vacuum chamber, the annular array structure cannot adapt to vacuum chamber sectors of different shapes and sizes, and has low versatility. In addition, the structure of the annular array structure is too complex, which increases the design and manufacturing cost of the lifting mechanism, and the installation and disassembly process of the annular array structure and the vacuum chamber sector is cumbersome, resulting in increased operational difficulty and time cost.

[0005] In other words, the existing lifting mechanism cannot meet the lifting requirements of vacuum chamber sectors of different sizes and weights, and the existing lifting mechanism cannot adjust the position and posture of the vacuum chamber sectors. If the center of gravity of the vacuum chamber sector deviates during lifting, it is easy to cause the vacuum chamber sector to shake, tilt or collide. In severe cases, it may even cause equipment damage or personnel safety hazards, affecting the safety of lifting. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a hoisting mechanism for vacuum chamber sectors.

At the same time, by setting the lifting arm of the second lifting ear assembly to an adjustable installation angle relative to the vacuum chamber sector, the vacuum chamber sector can be adjusted in position and posture during lifting, which can avoid deviation of the center of gravity of the vacuum chamber sector to a certain extent, thereby keeping the center of gravity of the vacuum chamber sector in a balanced state, and avoiding the risk of shaking, tilting or collision of the vacuum chamber sector during lifting to a certain extent, ensuring the stability of the vacuum chamber sector during lifting, thereby avoiding damage to the vacuum chamber sector or potential safety hazards to personnel, and improving the safety of the lifting mechanism.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0048] Combine Figure 1-Figure 7 As shown, the present application proposes a lifting mechanism 1000 for a vacuum chamber sector 300. Compared with the single lifting ear structure, the lifting mechanism 1000 for the vacuum chamber sector 300 can be used for vacuum chamber sectors 300 of different sizes and weights, and has a wide range of applications. On the other hand, it can also avoid stress concentration at the connection between the vacuum chamber sector 300 and the lifting mechanism 1000 to a certain extent, thereby extending the service life of the vacuum chamber sector 300. At the same time, it can also enable the vacuum chamber sector 300 to adjust its position and posture during the lifting process, and avoid deviation of the center of gravity of the vacuum chamber sector 300 to a certain extent, so that the center of gravity of the vacuum chamber sector 300 is in a balanced state, thereby avoiding the risk of shaking, tilting or collision of the vacuum chamber sector 300 during lifting to a certain extent, and ensuring the stability of the vacuum chamber sector 300.

[0049] Compared with the annular array structure, the lifting mechanism 1000 of the present application not only has a wide range of applications and a simple structure, but also has a simple installation and disassembly process with the vacuum chamber sector 300. To a certain extent, it reduces the operational difficulty and time cost of installing and disassembling the lifting mechanism 1000 without the vacuum chamber sector 300, and improves the lifting efficiency of the vacuum chamber sector 300.

[0050] The following describes a lifting mechanism 1000 for a vacuum chamber sector 300 according to an embodiment of the present invention with reference to the accompanying drawings.

[0051] like Figure 1 As shown, a lifting mechanism 1000 for a vacuum chamber sector 300 according to an embodiment of the present invention includes: a first lifting ear assembly 100 and a second lifting ear assembly 200 .

[0052] Among them, Figure 1 and Figure 3 As shown, the second lifting ear assembly 200 is connected to the vacuum chamber sector 300 at intervals from the first lifting ear assembly 100 . The second lifting ear assembly 200 includes a lifting arm 210 . The installation angle of the lifting arm 210 relative to the vacuum chamber sector 300 is adjustable.

[0053] It is worth noting that the present application sets the lifting arm 210 of the second lifting ear assembly 200 to be adjustable in installation angle relative to the vacuum chamber sector 300, so that the lifting arm 210 can adjust the position and posture of the vacuum chamber sector 300, which can avoid deviation of the center of gravity of the vacuum chamber sector 300 to a certain extent, thereby making the center of gravity of the vacuum chamber sector 300 in a balanced state, and thus avoiding to a certain extent the risk of shaking, tilting or collision of the vacuum chamber sector 300 during lifting, ensuring the stability of the vacuum chamber sector 300, and avoiding damage to the vacuum chamber sector 300 or hidden dangers to personnel safety, thereby improving the safety of use of the lifting mechanism 1000.

[0054] At the same time, by setting the first lifting ear assembly 100 and the second lifting ear assembly 200, and arranging the second lifting ear assembly 200 and the first lifting ear assembly 100 to be spaced and connected to the vacuum chamber sector 300, the first lifting ear assembly 100 and the second lifting ear assembly 200 can be used to jointly lift the vacuum chamber sector 300. Compared with the existing method of lifting the vacuum chamber sector 300 with a single lifting ear, the lifting mechanism 1000 can bear the weight of the vacuum chamber sector 300 and the lifting load during the installation and disassembly process, thereby ensuring the safety of the vacuum chamber sector 300 during the lifting operation, and enabling the lifting mechanism 1000 to withstand large-sized and heavy vacuum chamber sectors 300, thereby expanding the scope of application of the lifting mechanism 1000.

[0055] In addition, by using the first lifting ear assembly 100 and the second lifting ear assembly 200 to jointly lift the vacuum chamber sector 300, stress concentration can be avoided to a certain extent at the connection between the vacuum chamber sector 300 and the first lifting ear assembly 100 and the second lifting ear assembly 200, thereby avoiding local fatigue damage to the vacuum chamber sector 300 and avoiding the risk of breakage or deformation at the connection between the vacuum chamber sector 300 and the first lifting ear assembly 100 and the second lifting ear assembly 200, thereby extending the service life of the vacuum chamber sector 300 to a certain extent.

[0056] In summary, the hoisting mechanism 1000 for the vacuum chamber sector 300 of the present application can be applied to vacuum chamber sectors 300 of different sizes and masses, and can also ensure the safety and stability of the vacuum chamber sector 300 during the hoisting process.

[0057] In a specific example, the first lifting ear assembly 100 and the second lifting ear assembly 200 are suitable for lifting a large-sized and heavy vacuum chamber sector 300 (8.3 meters, 80 tons, 1 / 8 vacuum chamber sector 300), that is, the first lifting ear assembly 100 and the second lifting ear assembly 200 can lift multiple vacuum chamber sectors 300 in sequence, so that the multiple vacuum chamber sectors 300 are formed into a final vacuum chamber structure.

[0058] As can be seen from the above structure, the lifting mechanism 1000 for the vacuum chamber sector 300 of the embodiment of the present invention, by setting the first lifting ear assembly 100 and the second lifting ear assembly 200, and setting the second lifting ear assembly 200 and the first lifting ear assembly 100 to be spaced and connected to the vacuum chamber sector 300, can increase the contact area between the lifting mechanism 1000 and the vacuum chamber sector 300 compared to the existing method of lifting the vacuum chamber sector 300 with a single lifting ear, so that the lifting mechanism 1000 can withstand the large size and high weight of the vacuum chamber sector 300, and to a certain extent avoid stress concentration at the connection between the vacuum chamber sector 300 and the first lifting ear assembly 100 and the second lifting ear assembly 200.

[0059] At the same time, by setting the lifting arm 210 of the second lifting ear assembly 200 to an adjustable installation angle relative to the vacuum chamber sector 300, the position and posture of the vacuum chamber sector 300 can be adjusted during the lifting process, so that the center of gravity of the vacuum chamber sector 300 is in a balanced state, thereby ensuring the stability of the vacuum chamber sector 300 during lifting to a certain extent, thereby avoiding damage to the vacuum chamber sector 300 or potential safety hazards to personnel, and improving the safety of the lifting mechanism 1000.

[0060] It can be understood that, compared with the prior art, the present application not only simultaneously arranges the first lifting ear assembly 100 and the second lifting ear assembly 200, but also arranges the lifting arm 210 of the second lifting ear assembly 200 to be adjustable at an installation angle relative to the vacuum chamber sector 300, so that the lifting arm 210 can adjust the position and posture of the vacuum chamber sector 300, and to a certain extent, avoid the deviation of the center of gravity of the vacuum chamber sector 300, so that the center of gravity of the vacuum chamber sector 300 is in a balanced state, thereby to a certain extent avoiding the risk of shaking, tilting or collision of the vacuum chamber sector 300 during lifting, ensuring the stability of the vacuum chamber sector 300, and avoiding damage to the vacuum chamber sector 300 or hidden dangers to personnel safety, thereby improving the safety of use of the lifting mechanism 1000.

[0061] It should be noted that the first lifting ear assembly 100 here can be understood as a main lifting ear assembly, and the second lifting ear assembly 200 can be understood as an auxiliary lifting ear assembly. The second lifting ear assembly 200 assists the first lifting ear assembly 100 in lifting the vacuum chamber sector 300.

[0062] In some embodiments, the vacuum chamber sector 300 is made of stainless steel (for example, austenitic stainless steel 316LN, where 316LN is a nitrogen-strengthened improved version of 316L stainless steel with excellent corrosion resistance, high strength, and good welding properties), so that the vacuum chamber sector 300 can maintain a certain structural stability under complex loads such as strong magnetic fields, high temperatures, high pressures, or negative pressures, while maintaining a high vacuum environment, isolating the external atmosphere, and preventing gas molecules from interfering with plasma confinement and reactions.

[0063] In addition, the vacuum chamber sector 300 also has a certain degree of corrosion resistance, which prevents the vacuum chamber sector 300 from being damaged by residual gases (such as oxygen or water vapor) and chemical erosion in the vacuum environment.

[0064] In some embodiments, combined Figure 1 、 Figure 5 and Figure 6 As shown, the second lifting ear assembly 200 further includes a mounting base 220, which is suitable for being mounted on the vacuum chamber sector 300. The lifting arm 210 is cooperatively connected to the mounting base 220, and the mounting position of the lifting arm 210 on the mounting base 220 is adjustable. By mounting the mounting base 220 on the vacuum chamber sector 300, the second lifting ear assembly 200 is mounted on the vacuum chamber sector 300, thereby reducing the difficulty of installing the second lifting ear assembly 200 and the vacuum chamber sector 300, facilitating the use of the second lifting ear assembly 200 to lift the vacuum chamber sector 300, and thus ensuring the working performance of the second lifting ear assembly 200.

[0065] At the same time, by connecting the lifting arm 210 with the mounting seat 220, the mounting seat 220 can be used to provide a stable supporting force for the lifting arm 210, thereby ensuring the position stability of the lifting arm 210 and improving the working performance of the lifting arm 210.

[0066] In addition, by setting the installation position of the lifting arm 210 on the mounting seat 220 to be adjustable, since the mounting seat 220 is set on the vacuum chamber sector 300, the installation angle of the lifting arm 210 relative to the vacuum chamber sector 300 is adjustable, and the difficulty of adjusting the installation angle of the lifting arm 210 is reduced, so that the position and posture of the vacuum chamber sector 300 can be adjusted during the lifting process, and the deviation of the center of gravity of the vacuum chamber sector 300 can be avoided to a certain extent, and the balance of the center of gravity of the vacuum chamber sector 300 can be ensured, thereby avoiding the shaking, tilting or collision of the vacuum chamber sector 300 during lifting to a certain extent, and the vacuum chamber sector 300 is kept in a stable state, thereby ensuring the safety and stability of the vacuum chamber sector 300 during the lifting process, thereby ensuring the working performance of the lifting mechanism 1000.

[0067] In certain embodiments, the lifting arm 210 and the mounting base 220 in the second lifting ear assembly 200 may be separately mounted on the vacuum chamber sector 300 .

[0068] Of course, in some other embodiments, the lifting arm 210 and the mounting base 220 in the second lifting ear assembly 200 can also be assembled into a whole first, and then the assembled whole of the lifting arm 210 and the mounting base 220 is installed on the vacuum chamber sector 300.

[0069] Specifically, the lifting arm 210 and the mounting base 220 in the second lifting ear assembly 200 can be installed in a suitable manner (split or integral installation) according to the working conditions on site, and this application does not impose any restrictions thereon.

[0070] In some embodiments, as Figure 5 As shown, mounting bases 220 are provided on opposite sides of the lifting arm 210, and the mounting bases 220 on both sides are symmetrically arranged around the lifting arm 210. This allows the lifting arm 210 to be fixed by the two mounting bases 220, thereby improving the positional stability of the lifting arm 210 and ensuring the lifting performance of the second lifting eye assembly 200 to a certain extent.

[0071] In some embodiments, combined Figure 3 、 Figure 5 and Figure 6 As shown, the pendant arm 210 has a first mounting plate 211, and the mounting base 220 has a second mounting plate 221. The first mounting plate 211 and the second mounting plate 221 are fixedly connected by a first fastener 400. This allows the pendant arm 210 to be connected to the mounting base 220, reducing the difficulty of the connection between the pendant arm 210 and the mounting base 220.

[0072] At the same time, the first fastener 400 can enhance the connection stability between the first mounting plate 211 and the second mounting plate 221 to a certain extent, and then enhance the matching connection stability between the lifting arm 210 and the mounting seat 220, thereby ensuring the stability of the second lifting ear assembly 200 and ensuring the lifting performance of the second lifting ear assembly 200 to a certain extent.

[0073] In a specific example, the first mounting plate 211 and the second mounting plate 221 may be formed as flange plates.

[0074] In some embodiments, the first fastener 400 may be a bolt or a screw.

[0075] In a specific example, the first fastener 400 is a flange fixing bolt.

[0076] In some embodiments, as Figure 5As shown, first mounting plates 211 are respectively provided on opposite sides of the hanging arm 210 . The first mounting plates 211 on both sides are symmetrically arranged with the hanging arm 210 as the center, and the first mounting plates 211 on both sides are respectively connected with the mounting base 220 .

[0077] In some embodiments, combined Figure 5 and Figure 6 As shown, the first mounting plate 211 is provided with a plurality of first mounting holes 2111, which are sequentially arranged along the circumference of the first mounting plate 211. The second mounting plate 221 is provided with a plurality of second mounting holes 2211, which are sequentially arranged along the circumference of the second mounting plate 221. The first fastener 400 is sequentially engaged with the first mounting holes 2111 and the second mounting holes 2211. This achieves the mating connection between the first mounting plate 211 and the second mounting plate 221, and further the mating connection between the lifting arm 210 and the mounting seat 220. This reduces the difficulty of mating the lifting arm 210 and the mounting seat 220 while ensuring the connection strength between the lifting arm 210 and the mounting seat 220, thereby improving the structural stability of the second lifting ear assembly 200.

[0078] At the same time, by providing a plurality of first mounting holes 2111 arranged in sequence along and circumferentially on the first mounting plate 211 and providing a plurality of second mounting holes 2211 arranged in sequence along and circumferentially on the second mounting plate 221, when the first fastener 400 passes through the second mounting hole 2211 and is connected with different first mounting holes 2111, the installation position of the lifting arm 210 on the mounting seat 220 can be adjusted, so as to achieve the purpose of adjusting the installation angle of the lifting arm 210 relative to the vacuum chamber sector 300, so that the vacuum chamber sector 300 can be adjusted in position and posture during the lifting process, which can avoid the deviation of the center of gravity of the vacuum chamber sector 300 during the lifting process to a certain extent, ensure the balance of the center of gravity of the vacuum chamber sector 300, and improve the safety of the lifting.

[0079] In addition, by providing a plurality of first mounting holes 2111 and a plurality of second mounting holes 2211 to coordinately adjust the installation position of the suspension arm 210 on the mounting base 220 , the difficulty of adjusting the position of the suspension arm 210 can be reduced.

[0080] It should be noted that for different vacuum chamber sectors 300, the center of gravity of the vacuum chamber sector 300 is different. When installing, the second lifting ear assembly 200 can adjust the first fastener 400 to cooperate with different first mounting holes 2111 and different second mounting holes 2211 respectively, so as to adjust the installation angle of the lifting arm 210, thereby adjusting the center of gravity balance of the vacuum chamber sector 300.

[0081] In a specific example, the balance adjustment of the vacuum chamber sector 300 during the lifting process can be achieved by fine-tuning the installation angles of the first mounting plate 211 and the second mounting plate 221. The first fastener 400 cooperates with different first mounting holes 2111 and different second mounting holes 2211 to adjust the installation angle of the lifting arm 210, thereby adjusting the center of gravity of the vacuum chamber sector 300, so that the center of gravity of the vacuum chamber sector 300 can be in a balanced state, thereby ensuring the stability of the vacuum chamber sector 300 during the lifting process.

[0082] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0083] In some embodiments, as Figure 1 As shown, the mounting base 220 is disposed on the inner side of the peripheral wall of the vacuum chamber sector 300, and the lifting arm 210 is disposed through the vacuum chamber sector 300. Specifically, by disposing the mounting base 220 on the inner side of the peripheral wall of the vacuum chamber sector 300, compared to disposing the mounting base 220 on the outer side of the peripheral wall of the vacuum chamber sector 300, loosening of the connection between the mounting base 220 and the vacuum chamber sector 300 during the lifting process can be avoided to a certain extent, thereby ensuring the stability of the connection between the mounting base 220 and the vacuum chamber sector 300 to a certain extent.

[0084] At the same time, by setting the lifting arm 210 to pass through the vacuum chamber sector 300, on the one hand, it is convenient to achieve the coordinated connection between the lifting arm 210 and the second lock 800 described below, and on the other hand, it is also convenient to increase the contact area between the second lifting ear assembly 200 and the vacuum chamber sector 300, further increasing the connection strength between the second lifting ear assembly 200 and the vacuum chamber sector 300, thereby improving the lifting effect of the second lifting ear assembly 200 on the vacuum chamber sector 300.

[0085] It should be noted that if the mounting seat 220 is arranged on the outer side of the peripheral wall of the vacuum chamber sector 300, when the second lifting ear assembly 200 lifts the vacuum chamber sector 300, the connection between the second lifting ear assembly 200 and the outer side of the peripheral wall of the vacuum chamber sector 300 is prone to deformation or breakage under the action of the lifting force. However, the present application arranges the mounting seat 220 on the inner side of the peripheral wall of the vacuum chamber sector 300, so that the peripheral wall of the vacuum chamber sector 300 can have a certain supporting and stopping effect on the mounting seat 220, and thus to a certain extent can avoid the connection between the second lifting ear assembly 200 and the inner side of the peripheral wall of the vacuum chamber sector 300 from being deformed or broken again under the action of the lifting force, thereby ensuring the working stability of the second lifting ear assembly 200 and the vacuum chamber sector 300, and improving the lifting effect of the second lifting ear assembly 200 on the vacuum chamber sector 300.

[0086] In some embodiments, as Figure 4As shown, a window 310 is provided on the vacuum chamber sector 300, and the hanging arm 210 is passed through the window 310. This allows the hanging arm 210 to pass through the vacuum chamber sector 300, thereby reducing the difficulty of assembling the hanging arm 210 and the vacuum chamber sector 300.

[0087] In some embodiments, as Figure 5 and Figure 6 As shown, the lifting mechanism 1000 for the vacuum chamber sector 300 further includes an isolation member 500 and a second fastener 600. The mounting base 220 and the lifting arm 210 are both made of carbon steel, and the isolation member 500 is disposed between the mounting base 220 and the vacuum chamber sector 300. Specifically, by configuring the mounting base 220 and the lifting arm 210 to be made of carbon steel, the structural strength of the mounting base 220 and the lifting arm 210 is improved, thereby increasing the structural strength of the second lifting ear assembly 200, facilitating the use of the second lifting ear assembly 200 to lift the vacuum chamber sector 300 and improving the lifting effect.

[0088] It should be noted that, since the vacuum chamber sector 300 is made of stainless steel and the mounting seat 220 is made of carbon steel, galvanic corrosion (also known as contact corrosion or bimetallic corrosion) may occur when the stainless steel and carbon steel come into contact.

[0089] Based on this, the present application sets up an isolation member 500 and sets the isolation member 500 between the mounting seat 220 and the vacuum chamber sector 300, so as to use the isolation member 500 to separate the mounting seat 220 from the vacuum chamber sector 300, thereby avoiding corrosion between the mounting seat 220 and the vacuum chamber sector 300.

[0090] In some embodiments, the isolation member 500 is an isolation ring, and the isolation member 500 is made of stainless steel so that the isolation member 500 and the vacuum chamber sector 300 are made of the same material, thereby preventing the isolation member 500 from corroding the vacuum chamber sector 300, thereby ensuring the working performance of the vacuum chamber sector 300 to a certain extent.

[0091] Optionally, the second fastener 600 is detachably connected to the mounting base 220 and the vacuum chamber sector 300, respectively. This allows for detachable connection between the second lifting ear assembly 200 and the vacuum chamber sector 300. This not only reduces the difficulty of connecting the second lifting ear assembly 200 and the vacuum chamber sector 300, but also facilitates the use of the second lifting ear assembly 200 to lift the vacuum chamber sector 300. Furthermore, after the vacuum chamber sector 300 is lifted, the mounting base 220 and the vacuum chamber sector 300 can be easily disassembled to remove the second lifting ear assembly 200, making it reusable and reducing the cost of the lifting mechanism 1000.

[0092] In summary, the second lifting ear assembly 200 is a detachable structure. After the first lifting ear assembly 100 and the second lifting ear assembly 200 have completed lifting the vacuum chamber sector 300, the second lifting ear assembly 200 can be removed to achieve reuse of the second lifting ear assembly 200.

[0093] In some embodiments, as Figure 6 As shown, the second fastener 600 may be a bolt.

[0094] In some other embodiments, the second fastener 600 may also be a screw.

[0095] In some embodiments, as Figure 4 As shown, a plurality of third mounting holes 320 are provided around the window 310. The lifting arm 210 is inserted through the window 310, and the second fastener 600 is engaged with the third mounting holes 320. The third mounting holes 320 can reduce the difficulty of connecting the mounting base 220 and the vacuum chamber sector 300, thereby facilitating the mating connection between the second lifting ear assembly 200 and the vacuum chamber sector 300.

[0096] In the description of the present invention, features defined as "first", "second" and "third" may explicitly or implicitly include one or more such features, and are used to distinguish and describe features, without any distinction in order or importance.

[0097] In some embodiments, as Figure 7 As shown, the second fastener 600 includes a main body 610 and an isolating portion 620. The main body 610 is made of carbon steel, and the isolating portion 620 is sleeved around the outer periphery of the main body 610 and located between the main body 610 and the vacuum chamber sector 300. The carbon steel main body 610 provides the second fastener 600 with a certain strength, thereby enabling the second fastener 600 to securely mount the mounting base 220 on the vacuum chamber sector 300.

[0098] At the same time, by providing an isolation portion 620 on the second fastener 600 and arranging the isolation portion 620 between the main body 610 and the vacuum chamber sector 300, the main body 610 of the second fastener 600 and the vacuum chamber sector 300 can be separated by the isolation portion 620, which can avoid galvanic corrosion between the main body 610 of the second fastener 600 and the vacuum chamber sector 300 to a certain extent, thereby ensuring the working performance of the vacuum chamber sector 300.

[0099] In some embodiments, the isolation portion 620 is welded to the front end of the main body 610 , and the isolation portion 620 is equivalent to a threaded sleeve of a bolt.

[0100] In some embodiments, the first lifting ear assembly 100 and the vacuum chamber sector 300 are integrally formed. This can also be understood as the use of an integrally formed process to support the first lifting ear assembly 100 and the vacuum chamber sector 300. This reduces the difficulty of connecting the first lifting ear assembly 100 and the vacuum chamber sector 300 while also increasing the strength of the connection between the first lifting ear assembly 100 and the vacuum chamber sector 300, thereby improving the structural stability of the first lifting ear assembly 100 and thereby enhancing the lifting performance of the first lifting ear assembly 100, enabling the lifting mechanism 1000 to effectively lift the vacuum chamber sector 300.

[0101] In some embodiments, as Figure 4 As shown, the vacuum chamber sector 300 includes a first portion 330 located inside the vacuum chamber sector 300 and a second portion 340 located outside the vacuum chamber sector 300. A plurality of reinforcing ribs (not shown) are provided between the first portion 330 and the second portion 340. The reinforcing ribs can enhance the connection strength between the first portion 330 and the second portion 340, thereby increasing the strength of the entire structure of the vacuum chamber sector 300.

[0102] In some embodiments, the first lifting ear assembly 100 and the reinforcing rib are formed as an integral part. While ensuring that the first lifting ear assembly 100 and the vacuum chamber sector 300 can be formed as an integral part, it is also beneficial to improve the connection strength between the first lifting ear assembly 100 and the vacuum chamber sector 300, thereby improving the structural stability of the first lifting ear assembly 100 and ensuring the lifting performance of the first lifting ear assembly 100 to a certain extent.

[0103] Through the above-mentioned arrangement, during the assembly and molding of the vacuum chamber sector 300, the first lifting ear assembly 100 and the reinforcement ribs can be firstly processed and molded using an integrated molding process, and then the first part 330 located on the inner side of the vacuum chamber sector 300 can be welded to the multiple reinforcement ribs. After the welding is completed, the second part 340 located on the outer side of the vacuum chamber sector 300 can be welded to the reinforcement ribs. During the welding of the second part 340 and the reinforcement ribs, an avoidance opening can be reserved on the second part 340 so that the first lifting ear assembly 100 can be passed through the avoidance opening and arranged in the second part 340, thereby facilitating the connection of the first lifting ear assembly 100 with the first lock 700 described below.

[0104] In some embodiments, as Figure 1As shown, the lifting mechanism 1000 for the vacuum chamber sector 300 further includes a first lock 700 and a second lock 800. The first lock 700 is coupled to the first lifting lug assembly 100, and the second lock 800 is coupled to the second lifting lug assembly 200. The first lock 700 and the second lock 800 both include a lifting rope 710, and the length of the lifting rope 710 is adjustable. By configuring the first lock 700 to be coupled to the first lifting lug assembly 100 and the second lock 800 to be coupled to the second lifting lug assembly 200, the first and second lifting lug assemblies 100 and 200 can be hoisted using the first and second locks 700 and 800, thereby achieving the purpose of hoisting the vacuum chamber sector 300 and reducing the difficulty of hoisting the vacuum chamber sector 300.

[0105] At the same time, by setting the length of the lifting rope 710 to be adjustable, the position of the vacuum chamber sector 300 can be adjusted, thereby achieving the purpose of adjusting the position and posture of the hoisted vacuum chamber sector 300 and ensuring the safety of the vacuum chamber sector 300 during the hoisting process.

[0106] In some embodiments, after the length of the hanging rope 710 is adjusted, the first lock 700 and the second lock 800 can fix the length of the hanging rope 710 through a mechanical locking structure (such as a bolt lock, a snap lock or a spring lock, etc.), thereby preventing the hanging rope 710 from sliding due to vibration, gravity or operational errors to a certain extent, thereby ensuring the stability of the vacuum chamber sector 300 during lifting.

[0107] In summary, there are two ways to adjust the balance posture of the vacuum chamber sector 300. The first is to adjust the vacuum chamber sector 300 by adjusting the length of the lifting rope 710 of the first lock 700 and the second lock 800. The second is to ensure safety during the lifting process by adjusting the installation position of the lifting arm 210 relative to the mounting seat 220.

[0108] In some embodiments, combined Figure 1 and Figure 2 As shown, the first lifting ear assembly 100 is provided with a first connecting portion 110 on the side facing away from the vacuum chamber sector 300, and the first lock 700 includes a second connecting portion 720. The first connecting portion 110 and the second connecting portion 720 are detachably and positionally engaged. The detachable engagement between the first lock 700 and the first lifting ear assembly 100 reduces the difficulty of connecting the first lock 700 and the first lifting ear assembly 100, thereby improving the convenience of hoisting the vacuum chamber sector 300 to a certain extent. Furthermore, the first lock 700 can be detached from the first lifting ear assembly 100. Since the first lifting ear assembly 100 and the vacuum chamber sector 300 are formed as an integral part, after the first lock 700 and the first lifting ear assembly 100 are detached, the first lifting ear assembly 100 can be retained as part of the main body of the vacuum chamber sector 300.

[0109] In a specific example, when the vacuum chamber sector 300 is hoisted using the first lifting ear assembly 100, the first connecting part 110 and the second connecting part 720 are limited and matched, so that the first lock 700 and the first lifting ear assembly 100 are connected into an integral structure, thereby realizing the hoisting of the vacuum chamber sector 300 using the first lock 700; when the hoisting of the vacuum chamber sector 300 is completed, the limited and matched first connecting part 110 and the second connecting part 720 are disassembled, thereby realizing the disassembly of the first lock 700 and the first lifting ear assembly 100.

[0110] In some embodiments, combined Figure 1 and Figure 2 As shown, the first connecting portion 110 is a connecting protrusion, and the second connecting portion 720 is provided with a connecting groove 721. The connecting protrusion is limitedly engaged in the connecting groove 721. This realizes the limited engagement between the first connecting portion 110 and the second connecting portion 720, thereby facilitating the limited engagement between the first lock 700 and the first lifting ear assembly 100, reducing the difficulty of connecting the first lock 700 and the first lifting ear assembly 100, and improving the convenience of lifting the vacuum chamber sector 300 to a certain extent.

[0111] In addition, the geometric shapes of the connecting protrusion and the connecting groove 721 can provide clear guidance, thereby ensuring to a certain extent that the first lock 700 and the first ear assembly 100 are quickly positioned and aligned during assembly, reducing the difficulty of limiting the matching of the first connecting part 110 and the second connecting part 720.

[0112] In a specific example, Figure 2 As shown, the first connecting portion 110 is connected to one end of the first lifting ear assembly 100, so that the first lifting ear assembly 100 is in a "T"-shaped structure, and the connecting groove 721 is in a "T"-shaped groove structure corresponding to the first connecting portion 110. The first connecting portion 110 is limited and fitted in the connecting groove 721, so that the first lifting ear assembly 100 and the first lock 700 can withstand vertical tension and horizontal shear force, thereby preventing the first connecting portion 110 from falling out of the connecting groove 721 to a certain extent, thereby ensuring the stability of the vacuum chamber sector 300 during lifting.

[0113] The following describes a method for hoisting a vacuum chamber sector 300 according to an embodiment of the present invention with reference to the accompanying drawings.

[0114] like Figure 8 As shown, a method for hoisting a vacuum chamber sector 300 according to an embodiment of the present invention includes the aforementioned hoisting mechanism 1000. The hoisting method includes:

[0115] S1 . Connect the first lifting ear assembly 100 and the second lifting ear assembly 200 to the vacuum chamber sector 300 at intervals.

[0116] In this step, the first lifting ear assembly 100 and the second lifting ear assembly 200 are used to jointly lift the vacuum chamber sector 300. Compared with the existing method of lifting the vacuum chamber sector 300 with a single lifting ear, the lifting mechanism 1000 can bear the weight of the vacuum chamber sector 300 and the lifting load during the installation and disassembly process, thereby ensuring the safety of the vacuum chamber sector 300 during the lifting operation, and enabling the lifting mechanism 1000 to withstand large-sized and high-weight vacuum chamber sectors 300; at the same time, it can also avoid local fatigue damage of the vacuum chamber sector 300 during the lifting process to a certain extent, so as to avoid the risk of breakage or deformation at the connection between the vacuum chamber sector 300 and the first lifting ear assembly 100 and the second lifting ear assembly 200 during the lifting process, thereby extending the service life of the vacuum chamber sector 300 to a certain extent.

[0117] S2. Adjust the installation angle of the lifting arm 210 of the second lifting ear assembly 200 relative to the vacuum chamber sector 300.

[0118] In this step, the lifting arm 210 can adjust the position and posture of the vacuum chamber sector 300, which can avoid the deviation of the center of gravity of the vacuum chamber sector 300 during the lifting process to a certain extent, so that the center of gravity of the vacuum chamber sector 300 during the lifting process is in a balanced state, thereby avoiding the risk of shaking, tilting or collision of the vacuum chamber sector 300 during lifting to a certain extent, ensuring the stability of the vacuum chamber sector 300 during the lifting process, and avoiding damage to the vacuum chamber sector 300 during the lifting process or hidden dangers to personnel safety, thereby improving the safety of the lifting of the vacuum chamber sector 300.

[0119] S3. Control the first lifting ear assembly 100 and the second lifting ear assembly 200 to move.

[0120] In this step, since the first lifting ear assembly 100 and the second lifting ear assembly 200 are both connected to the vacuum chamber sector 300, the movement of the vacuum chamber sector 300 can be controlled by controlling the movement of the first lifting ear assembly 100 and the second lifting ear assembly 200, thereby realizing the lifting of the vacuum chamber sector 300.

[0121] It can be seen from the above method that the lifting method for the vacuum chamber sector 300 of the embodiment of the present invention can not only lift the vacuum chamber sector 300 of large size and high weight, but also to a certain extent avoid stress concentration at the connection between the vacuum chamber sector 300 and the first lifting ear assembly 100 and the second lifting ear assembly 200 during the lifting process.

[0122] At the same time, the position and posture of the vacuum chamber sector 300 can be adjusted during the lifting process, so that the center of gravity of the vacuum chamber sector 300 is in a balanced state during the lifting process, thereby ensuring the stability of the vacuum chamber sector 300 during lifting to a certain extent, thereby avoiding damage to the vacuum chamber sector 300 or potential safety hazards to personnel, and improving the safety of the lifting of the vacuum chamber sector 300.

[0123] In some embodiments, when hoisting the vacuum chamber sector 300, the first lifting ear assembly 100 and the second lifting ear assembly 200 can be first connected to the vacuum chamber sector 300 at intervals, and the installation angle of the lifting arm 210 of the second lifting ear assembly 200 relative to the vacuum chamber sector 300 can be adjusted based on experience. Then, the first lifting ear assembly 100 and the second lifting ear assembly 200 are controlled to move to achieve the hoisting of the vacuum chamber sector 300. During the hoisting, the center of gravity of the vacuum chamber sector 300 is detected in real time. When it is detected that the center of gravity of the vacuum chamber sector 300 deviates, the first lifting ear assembly 100 and the second lifting ear assembly 200 are first used to control the movement of the vacuum chamber sector 300 to achieve the placement of the vacuum chamber sector 300 on the original support platform. Then, the installation angle of the lifting arm 210 of the second lifting ear assembly 200 relative to the vacuum chamber sector 300 is adjusted to achieve the adjustment of the center of gravity of the vacuum chamber sector 300 during the hoisting process.

[0124] The center of gravity of the vacuum chamber sector 300 can be measured by a measurement system, and the specific measurement method is not limited in this application.

[0125] In some embodiments, the surface geometric data of the vacuum chamber sector 300 can be obtained by using a laser tracker or a structured light scanner, and combined with the CAD model or CT scan data, the material density (such as metal, insulation layer) of each area can be assigned, and the mass distribution and center of gravity coordinates can be calculated by integration.

[0126] It should be noted that, during the hoisting process, after the center of gravity of the vacuum chamber sector 300 is adjusted using the second lifting ear assembly 200 , the vacuum chamber sector 300 is hoisted again.

[0127] In some embodiments, when the lifting mechanism 1000 includes a first lock 700 and a second lock 800, after the vacuum chamber sector 300 is lifted again, if it is detected that the center of gravity of the vacuum chamber sector 300 deviates, the position and posture of the vacuum chamber sector 300 can be adjusted again by adjusting the length of the lifting rope 710 to ensure the safety of the vacuum chamber sector 300 during the lifting process.

[0128] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0129] The hoisting mechanism 1000 for the vacuum chamber sector 300 and other components of the hoisting method according to the embodiment of the present invention, such as the specific structure of the vacuum chamber sector 300 , are well known to those skilled in the art and will not be described in detail here.

In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0131] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
