Description

Technical Field

[0001] This invention specifically relates to a large-scale module transfer device, system, and method. Background Technology

[0002] Modular technology is an advanced design and construction technology. Applying it to the design and construction process of nuclear power plants can significantly reduce on-site construction work, reduce safety hazards, shorten construction period, and reduce project costs. It is an effective means to improve nuclear power plant design and construction technology.

[0003] Current modular design and construction technology for nuclear power plants still suffers from problems such as small individual module size and low integration. The main constraint on making nuclear power modules "larger and more complete" is the hoisting and placement of large modules. The hoisting and placement methods used in the modular construction of nuclear power plants are affected by factors such as the lifting capacity of large crawler cranes, crane location, and clearance height. The overall weight of large nuclear power plant modules has reached the limit of the hoisting capacity of heavy-duty cranes.

[0004] The super-modular design and construction method transforms traditional crane hoisting into a jacking-and-moving method, overcoming the limitations of crane lifting capacity on module size and weight. The "jacking-and-moving" technology is key to the success of this method for nuclear power plants. Reactor building modules can exceed 40 meters in diameter, 20 meters in height, and weigh over 3,000 tons. How to transport such large modules to their installation location is the first problem the super-modular method must solve. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art by providing a large module transfer device that can achieve the dual purpose of stable transportation of large modules and providing conditions for the withdrawal of the transfer device. The present invention also provides a system including the device and a method for transferring large modules using the system.

[0006] The technical solution adopted to solve the technical problem of this invention is:

[0007] This invention provides a large module transfer device, comprising:

[0008] The system includes a moving mechanism and a support platform. The support platform supports the large module. The moving mechanism includes a self-propelled vehicle connected to the support platform, which drives the support platform to move horizontally.

[0009] The top surface of the support platform is provided with a through slot, which extends along the translational direction of the support platform and is used for the lifting mechanism to pass through. The through slot includes a first through slot, a second through slot, ..., an Nth through slot, distributed sequentially along the translational direction of the support platform. The first through slot penetrates the front side of the support platform in the translational direction, and the Nth through slot penetrates the rear side of the support platform in the translational direction, where N ≥ 2.

[0010] The distance between the central axis of the lifting mechanism raised at the front end of the M+1th through slot and the front side of the support platform is less than or equal to the distance between the central axis of the lifting mechanism raised at the rear end of the Mth through slot and the front side of the support platform, where M≥1.

[0011] Optionally, the Mth through slot and the Mth-to-last through slot are set accordingly, where M≥1.

[0012] Optionally, the through slot is an oblong hole, and the semi-circular holes at both ends of the oblong hole match the lifting mechanism.

[0013] Optionally, N equals 3.

[0014] Optionally, multiple first through slots, second through slots, ..., Nth through slots are provided, and the multiple through slots of each type are arranged at intervals along a direction perpendicular to the translation of the support platform.

[0015] Furthermore, the pattern of multiple through slots of each type projected onto the upper surface of the support platform is symmetrical about the diameter of the upper surface of the support platform parallel to its translation direction.

[0016] Optionally, the two ends of the large module perpendicular to the translation direction of the support platform extend outward relative to the support platform for the lifting mechanism to lift.

[0017] The present invention also provides a large module transfer system, including a lifting mechanism and the aforementioned large module transfer device. The lifting mechanism includes a first lifting mechanism and a second lifting mechanism, which are distributed at intervals along the circumference of the support platform.

[0018] After the transfer device transports the large module to its destination, the second lifting mechanism is used to lift the rear edge of the bottom surface of the large module from the Nth through slot. The first lifting mechanism is located between the destination and the front edge of the bottom surface of the support platform and is divided into N groups. The N groups of first lifting mechanisms correspond one-to-one with the first to Nth through slots. The first group of first lifting mechanisms is used to lift the front edge of the bottom surface of the large module from the first through slot. After the large module is lifted by the second lifting mechanism and the first group of first lifting mechanisms to detach from the support platform, the large module transfer device begins to move horizontally to withdraw from between the large module and the destination. When the first group of first lifting mechanisms is located at the rear end of the first through slot, the second group of first lifting mechanisms is used to lift the front edge of the bottom surface of the large module from the second through slot. At the same time, the first group of first lifting mechanisms descends below the bottom surface of the support platform, so that the large module transfer device can continue to withdraw. This process continues until the Nth group of first lifting mechanisms rises from the Nth through slot to lift the front edge of the bottom surface of the large module, completing the withdrawal of the transfer device from the destination and the large module.

[0019] Optionally, the Mth through slot and the Mth-to-last through slot are set up correspondingly, M≥1, and the Mth through slot and the Mth-to-last through slot share a set of first lifting mechanisms.

[0020] Optionally, the two ends of the large module perpendicular to the translation direction of the support platform extend outward relative to the support platform.

[0021] The lifting mechanism also includes a third lifting mechanism and a fourth auxiliary lifting mechanism. The third lifting mechanism is used to support the destination and the bottom surface of the large module at one end perpendicular to the direction of translation of the support platform. The fourth lifting mechanism is used to support the destination and the bottom surface of the large module at the other end perpendicular to the direction of translation of the support platform.

[0022] The present invention also provides a method for transporting large modules using the above-described large module transport system, comprising:

[0023] S1: The large module transfer device transports large modules to their destination.

[0024] S2: A lifting mechanism is installed between the destination and the bottom surface of the support platform. The lifting mechanism includes a first lifting mechanism and a second lifting mechanism, which are distributed at intervals along the circumference of the support platform. The second lifting mechanism rises from the Nth through slot to lift the rear edge of the bottom surface of the large module. The first lifting mechanism is located between the destination and the front edge of the bottom surface of the support platform, and a first group of first lifting mechanisms rises from the first through slot to lift the front edge of the bottom surface of the large module, so that the large module is lifted to the point of detachment from the support platform.

[0025] S3: The large module transfer device begins to move horizontally to withdraw from the large module and the destination. When the first lifting mechanism of the first group is located at the rear end of the first channel, the second lifting mechanism of the first group rises from the second channel to lift the front edge of the bottom of the large module. At the same time, the first lifting mechanism of the first group descends below the bottom surface of the support platform, so that the large module transfer device can continue to withdraw. This process continues until the Nth lifting mechanism of the first group rises from the Nth channel to lift the front edge of the bottom of the large module, thus completing the withdrawal of the transfer device from the destination and the large module.

[0026] Optionally, the two ends of the large module perpendicular to the translation direction of the support platform extend outward relative to the support platform.

[0027] Step S2 further includes: setting up a third lifting mechanism between the destination and one end of the large module bottom surface perpendicular to the translation direction of the support platform, and setting up a fourth lifting mechanism between the destination and the other end of the large module bottom surface perpendicular to the translation direction of the support platform.

[0028] In this invention, the platform supporting the large module is cleverly designed by creating multiple through slots for the lifting mechanisms to pass through. These slots are arranged sequentially along the translational direction of the support platform, with the distance between the front end of the next slot and the front side of the support platform being less than or equal to the distance between the rear end of the previous slot and the front side of the support platform. By arranging lifting mechanisms corresponding to the through slots between the front edge of the bottom of the large module and its destination, when the large module transfer device reaches the rear end of the previous set of lifting mechanisms in the previous set of through slots, the next set of lifting mechanisms rises from the next set of through slots to smoothly lift the large module together with the lifting mechanism at the other end of the translational direction. At the same time, the previous set of lifting mechanisms descends below the bottom surface of the support platform, allowing the transfer device to be completely withdrawn from between the large module and its destination.

Detailed Implementation

[0040] The technical solutions of the invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without creative effort are within the scope of the invention.

[0041] In the description of this invention, it should be noted that the use of terms such as "above" to indicate orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0042] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection," "setting," "installation," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] This invention provides a large module transfer device, comprising:

[0045] The system includes a moving mechanism and a support platform. The support platform supports the large module. The moving mechanism includes a self-propelled vehicle connected to the support platform, which drives the support platform to move horizontally.

[0046] The top surface of the support platform is provided with a through slot, which extends along the translational direction of the support platform and is used for the lifting mechanism to pass through. The through slot includes a first through slot, a second through slot, ..., an Nth through slot, distributed sequentially along the translational direction of the support platform. The first through slot penetrates the front side of the support platform in the translational direction, and the Nth through slot penetrates the rear side of the support platform in the translational direction, where N ≥ 2.

[0047] The distance between the central axis of the lifting mechanism raised at the front end of the M+1th through slot and the front side of the support platform is less than or equal to the distance between the central axis of the lifting mechanism raised at the rear end of the Mth through slot and the front side of the support platform, where M≥1.

[0048] The present invention also provides a large module transfer system, including a lifting mechanism and the aforementioned large module transfer device. The lifting mechanism includes a first lifting mechanism and a second lifting mechanism, which are distributed at intervals along the circumference of the support platform.

[0049] After the transfer device transports the large module to its destination, the second lifting mechanism is used to lift the rear edge of the bottom surface of the large module from the Nth through slot. The first lifting mechanism is located between the destination and the front edge of the bottom surface of the support platform and is divided into N groups. The N groups of first lifting mechanisms correspond one-to-one with the first to Nth through slots. The first group of first lifting mechanisms is used to lift the front edge of the bottom surface of the large module from the first through slot. After the large module is lifted by the second lifting mechanism and the first group of first lifting mechanisms to detach from the support platform, the large module transfer device begins to move horizontally to withdraw from between the large module and the destination. When the first group of first lifting mechanisms is located at the rear end of the first through slot, the second group of first lifting mechanisms is used to lift the front edge of the bottom surface of the large module from the second through slot. At the same time, the first group of first lifting mechanisms descends below the bottom surface of the support platform, so that the large module transfer device can continue to withdraw. This process continues until the Nth group of first lifting mechanisms rises from the Nth through slot to lift the front edge of the bottom surface of the large module, completing the withdrawal of the transfer device from the destination and the large module.

[0050] The present invention also provides a method for transporting large modules using the above-described large module transport system, comprising:

[0051] S1: The large module transfer device transports large modules to their destination.

[0052] S2: A lifting mechanism is installed between the destination and the bottom surface of the support platform. The lifting mechanism includes a first lifting mechanism and a second lifting mechanism, which are distributed at intervals along the circumference of the support platform. The second lifting mechanism rises from the Nth through slot to lift the rear edge of the bottom surface of the large module. The first lifting mechanism is located between the destination and the front edge of the bottom surface of the support platform, and a first group of first lifting mechanisms rises from the first through slot to lift the front edge of the bottom surface of the large module, so that the large module is lifted to the point of detachment from the support platform.

[0053] S3: The large module transfer device begins to move horizontally to withdraw from the large module and the destination. When the first lifting mechanism of the first group is located at the rear end of the first channel, the second lifting mechanism of the first group rises from the second channel to lift the front edge of the bottom of the large module. At the same time, the first lifting mechanism of the first group descends below the bottom surface of the support platform, so that the large module transfer device can continue to withdraw. This process continues until the Nth lifting mechanism of the first group rises from the Nth channel to lift the front edge of the bottom of the large module, thus completing the withdrawal of the transfer device from the destination and the large module.

[0054] Example 1:

[0055] like Figure 1 As shown, this embodiment provides a large module transfer device, including:

[0056] The moving mechanism includes a support platform 1, which supports large modules. The moving mechanism includes a self-propelled vehicle 7 connected to the support platform 1, used to drive the support platform 1 to move horizontally.

[0057] A through slot 4 is provided on the top surface of the support platform 1. The through slot 4 extends along the translational direction of the support platform 1 and is used for the lifting mechanism to pass through. It includes a first through slot, a second through slot, ..., an Nth through slot distributed sequentially along the translational direction of the support platform 1. The first through slot penetrates the front side of the support platform 1 in the translational direction, and the Nth through slot penetrates the rear side of the support platform 1 in the translational direction. N≥2.

[0058] The distance between the central axis of the lifting mechanism raised at the front end of the M+1th channel and the front side of the support platform 1 is less than or equal to the distance between the central axis of the lifting mechanism raised at the rear end of the Mth channel and the front side of the support platform 1, where M≥1.

[0059] Therefore, by cleverly designing the support platform 1 that supports the large module, and by arranging lifting mechanisms corresponding to the through slots between the front edge of the bottom of the large module and the destination, when the large module transfer device reaches the rear end of the previous set of lifting mechanisms located in the previous column of through slots, the next set of lifting mechanisms rises from the next column of through slots, together with the lifting mechanism at the other end of the translation direction to smoothly lift the large module. At the same time, the previous set of lifting mechanisms descends below the bottom surface of the support platform 1, so that the transfer device can be completely withdrawn from between the large module and the destination.

[0060] Specifically, the self-propelled vehicle 7 is a self-propelled walking vehicle, which enables the transfer device to move independently, and the support platform 1 is a box girder steel structure platform.

[0061] In this embodiment, the Mth through slot and the Mth-to-last through slot are set up correspondingly, and M≥1, so that the Mth through slot and the Mth-to-last through slot can share the same set of lifting mechanisms, thereby reducing the arrangement of lifting mechanisms and saving costs.

[0062] To ensure the support strength of the support platform, the distance between the central axis of the lifting mechanism raised at the front end of the M+1th through slot and the front side of the support platform 1 is preferably equal to the distance between the central axis of the lifting mechanism raised at the rear end of the Mth through slot and the front side of the support platform 1.

[0063] In the above case, in order to avoid the through-slot wall interfering with the lifting mechanism, the through-slot 4 is designed as an oblong hole, and the semi-circular holes at both ends of the oblong hole are matched with the lifting mechanism.

[0064] To achieve smooth lifting of the large module, multiple lifting mechanisms are needed to lift the large module at both ends along the translational direction of the support platform. Therefore, in this embodiment, multiple first through slots, second through slots, ..., Nth through slots are provided. The multiple through slots of each type are arranged at intervals along the direction perpendicular to the translational direction of the support platform 1.

[0065] Furthermore, the pattern of multiple through slots of each type projected onto the upper surface of the support platform 1 is symmetrical about the diameter of the upper surface of the support platform 1 parallel to its translation direction.

[0066] In this embodiment, N equals 3. See also Figure 1 There are three first and three third through slots, and they are arranged correspondingly. The projection of the middle through slot is symmetrical about the diameter, and the projections of the two through slots on both sides are symmetrical about the diameter. There are four second through slots, and their projections are symmetrical about the diameter in pairs.

[0067] In this embodiment,

[0068] The two ends of the large module, perpendicular to the translational direction of the support platform 1, extend outward relative to the support platform 1 to be lifted by the lifting mechanism. In this way, lifting mechanisms can be added at the destination and at both ends of the large module perpendicular to the translational direction of the support platform 1, resulting in better lifting stability.

[0069] To achieve the vertical construction of the nuclear power plant building, large modules need to be transferred to pre-cast modules. In this embodiment, for example... Figure 2 As shown, the moving mechanism also includes a climbing mechanism, through which the self-propelled vehicle 7 is connected to the support platform 1.

[0070] The climbing mechanism includes climbing pole 6 and climbing drive unit.

[0071] The climbing pole 6 passes through the support platform 1, its lower end is connected to the self-propelled vehicle 7, and its upper end protrudes from the large module. The climbing drive unit is connected to the support platform 1 and is used to drive the support platform 1 to rise and fall relative to the climbing pole 6, or to drive the climbing pole 6 to rise and fall relative to the support platform 1.

[0072] The process of transferring the large module to the already cast molded module in this embodiment is as follows:

[0073] A1: The transfer device transports the upper-level large module 14 to the next level large module 15, which has been poured.

[0074] A2: As Figure 3 As shown, the climbing drive unit drives the support platform 1 to climb upward on the climbing pole 6, until the distance between the bottom surface of the support platform 1 and the next level large module 15 is greater than or equal to the height of a self-propelled vehicle 7.

[0075] A3: As Figure 4 As shown, the first row of unraised climbing poles 6 in the forward direction of the lifting and transfer device is raised until the bottom surface of the self-propelled vehicle 7 connected to the row of climbing poles 6 is flush with the top surface of the next level large module 15. The transfer device moves forward until the self-propelled vehicle 7 connected to the row of climbing poles 6 is supported on the top surface of the next level large module 15.

[0076] A4: As Figure 5 As shown, repeat step A3 until all the self-propelled vehicles 7 are supported on the top surface of the next level large module 15.

[0077] A5: As Figure 6 As shown, a lifting mechanism is provided between the next-level large module 15 and the previous-level large module 14.

[0078] Specifically, the lifting mechanism includes a first lifting mechanism 13 and a second lifting mechanism 12. The first lifting mechanism 13 and the second lifting mechanism 12 are distributed circumferentially along the support platform 1. The second lifting mechanism 12 rises from the Nth through slot to lift the rear edge of the bottom surface of the large module. The first lifting mechanism 13 is located between the destination and the front edge of the bottom surface of the support platform 1. The first group of first lifting mechanisms 13 rises from the first through slot to lift the front edge of the bottom surface of the upper-level large module 14, so that the upper-level large module 14 is lifted to detach from the support platform 1. Then the climbing pole is removed and the self-propelled vehicle 7 is connected to the support platform.

[0079] A6:

[0080] A6.1: For example Figure 10 As shown, the large module transfer device begins to move backward to withdraw from between the next-level large module 15 and the previous-level large module 14. When the first group of first lifting mechanisms 13 is located at the rear end of the first through slot, the second group of first lifting mechanisms 13 rises from the second through slot to lift the front edge of the bottom of the previous-level large module 14. At the same time, the first group of first lifting mechanisms 13 descends below the bottom surface of the support platform 1, so that the large module transfer device can continue to withdraw. This process continues until the Nth group of first lifting mechanisms 13 rises from the Nth through slot to lift the front edge of the bottom of the previous-level large module 14.

[0081] A6.2: Simultaneously, the transfer device moves backward until the first row of un-lowered self-propelled vehicles 7 in the backward direction of the transfer device is suspended. The climbing pole 6 passes through the support platform 1 and connects to the suspended self-propelled vehicle 7. The connection between the suspended self-propelled vehicle 7 and the support platform 1 is then released. The climbing pole 6 is lowered until the connected self-propelled vehicle 7 touches the ground. Figure 7 As shown.

[0082] A7: Repeat step 6.2 until all self-propelled vehicles 7 are on the ground and the support platform 1 is removed from between the upper and lower large modules, as follows. Figure 8 As shown.

[0083] A8: As Figure 9 As shown, each lifting mechanism retracts into the next-level large module 15 and / or the previous-level large module 14, so that the previous-level large module 14 is supported on the next-level large module 15.

[0084] Specifically, since the upper-level large module 14 is a frame structure before casting, it can be adapted by designing a receiving groove on its bottom surface that can accommodate the retracted lifting mechanism, and a recycling channel connected to the receiving groove on its top surface, so that the lifting mechanism can be sent into the receiving groove through the recycling channel, or moved out of the receiving groove through the recycling channel.

[0085] In this embodiment, the front edge of the bottom surface of the support platform is provided with a connecting seat 8. Before step S3, the following steps are also included: the transfer device moves forward until the connecting seat 8 extends into the upper space of the next level large module 15, and the connecting vehicle 16, which is supported on the next level large module 15 and located below the connecting seat 8, is detachably connected to the connecting seat 8.

[0086] By supporting the front end of the transfer device on the next-level large module 15 with the connecting vehicle 16, it is possible to prevent the transfer device from tipping over after the first row of moving mechanisms is lifted. After the first row of moving mechanisms is lifted, the connecting vehicle is also used to drive and guide the transfer device to move forward on the next-level large module 15.

[0087] In this embodiment,

[0088] The climbing drive unit includes multiple telescopic cylinders 5, which are arranged in a circumferential pattern around the climbing pole 6. The telescopic cylinders 5 are fixedly connected to the support platform 1 and provide support power to the support platform 1.

[0089] The telescopic cylinder 5 repeats the sequence of actions: one of its fixed part and telescopic part is connected to the climbing pole 6, and the other is disconnected from the climbing pole 6. The telescopic cylinder 5 extends and retracts, and one of its fixed part and telescopic part is disconnected from the climbing pole 6, and the other is connected to the climbing pole 6. The telescopic cylinder 5 resets, so that the support platform 1 rises and falls relative to the climbing pole 6, or the climbing pole 6 rises and falls relative to the support platform 1.

[0090] In this embodiment, the telescopic part of the telescopic cylinder 5 is located below its fixed part. The climbing mechanism realizes the process of the support platform 1 rising relative to the climbing pole 6 as follows: the fixed part is connected to the climbing pole 6, the telescopic part is disconnected from the climbing pole 6 - the telescopic cylinder 5 retracts - the fixed part is disconnected from the climbing pole 6, the telescopic part is connected to the climbing pole 6 - the telescopic cylinder 5 extends, and so on, thereby realizing the rise of the support platform 1 relative to the climbing pole 6.

[0091] The process by which the climbing mechanism lowers the support platform 1 relative to the climbing pole 6 is the reverse of the above-described upward process, and will not be described again here.

[0092] The process by which the climbing mechanism enables a row of climbing poles 6 to rise or fall relative to the support platform 1 is the same as the process by which the support platform 1 rises or falls relative to the climbing poles 6, and will not be described again here.

[0093] In this embodiment, both the fixed part and the telescopic part of the telescopic cylinder 5 are connected to the climbing rod 6 via bite teeth.

[0094] In this embodiment,

[0095] The support platform 1 is provided with a mounting hole 2 and a through hole 3. The through hole 3 is coaxially arranged with the mounting hole 2 and penetrates the upper and lower surfaces of the support platform 1. The through hole 3 is matched with the climbing pole 6. The climbing pole 6 penetrates the support platform 1 through the through hole 3. The climbing drive unit is located in the mounting hole 2.

[0096] The first challenge in applying the "lift-and-transfer" system to the super-modular approach is designing the "lift-and-transfer" platform. This design needs to address three key issues: 1) High load-bearing capacity requirements: For example, a reactor building segment module has a diameter exceeding 40 meters, a height exceeding 20 meters, and a weight exceeding 3000 tons; 2) Uneven load distribution: Again, using a reactor building segment module as an example, the steel containment vessel and shielding building are circular and unconnected, resulting in uneven load distribution; 3) Complex "entry-and-exit" process: After a single super-module segment is constructed in the module factory, the "lift-and-transfer" platform needs to be moved to the lower part of the module to support its weight. Furthermore, after the platform lifts the module to the designated position, it needs to be removed. In other words, the platform must be able to achieve both longitudinal and lateral translation while bearing the module's weight.

[0097] In this embodiment, the alternating channels on the steel structure platform provide a movement path for the platform's removal, avoiding interference between the platform and the jacks. During the lifting and translation operation of large segment modules in a nuclear power plant, the support platform 1, supported by a climbing mechanism, transports the large segment modules to a predetermined position. Multiple jacks are installed at the support points of the large segment modules, supporting the weight of the entire segment module and providing conditions for the removal of the support platform 1. At this time, supported by the self-propelled vehicle 7, the support platform 1 begins to move along the extension direction of the alternating channels 4. When the support platform 1 moves to the limit position of the previous channel 4, the jacks corresponding to the next channel 4 replace the previous jacks to support the lifting of the large module segment. After the first-level jack support is removed, the large segment module continues to move to the limit position of the next channel. Repeating this process can achieve the overall removal of the box girder steel structure platform.

[0098] The present invention proposes the above-mentioned transfer device, which can transform the hoisting and positioning method of large nuclear power plant modules into a lifting and horizontal moving method. This can overcome the limitations of crane lifting capacity on the size and weight of modules, significantly improve the size and completion of individual nuclear power plant modules, thereby improving the modular design and construction level of nuclear power plants, significantly reducing the construction cycle of nuclear power plants, and improving economic efficiency.

[0099] Example 2:

[0100] This embodiment provides a large module transfer system, including a lifting mechanism and the large module transfer device of Embodiment 1. The lifting mechanism includes a first lifting mechanism 13 and a second lifting mechanism 12, which are distributed at intervals along the circumference of the support platform 1.

[0101] After the transfer device transports the large module to its destination, the second lifting mechanism 12 is used to lift the rear edge of the bottom surface of the large module from the Nth through slot. The first lifting mechanism 13 is located between the destination and the front edge of the bottom surface of the support platform 1, and is divided into N groups. The N groups of first lifting mechanisms 13 correspond one-to-one with the first to Nth through slots. The first group of first lifting mechanisms 13 is used to lift the front edge of the bottom surface of the large module from the first through slot. After the large module is lifted by the second lifting mechanism 12 and the first group of first lifting mechanisms 13 to detach from the support platform 1, the large module is transferred... The transport device begins to move horizontally to withdraw from the large module and the destination. When the first lifting mechanism 13 of the first group is located at the rear end of the first channel, the second lifting mechanism 13 is used to rise from the second channel to lift the front edge of the bottom of the large module. At the same time, the first lifting mechanism 13 of the first group descends below the bottom surface of the support platform 1, so that the large module transport device can continue to withdraw. This process continues until the Nth lifting mechanism 13 rises from the Nth channel to lift the front edge of the bottom of the large module, completing the withdrawal of the transport device from the destination and the large module.

[0102] In this embodiment, the Mth through slot and the Mth-to-last through slot are set up correspondingly, M≥1, and the Mth through slot and the Mth-to-last through slot share a set of first lifting mechanisms 13.

[0103] In this embodiment,

[0104] The two ends of the large module, perpendicular to the translation direction of the support platform 1, extend outward relative to the support platform 1.

[0105] The lifting mechanism also includes a third lifting mechanism 11 and a fourth auxiliary lifting mechanism. The third lifting mechanism 11 is used to support the destination and the bottom surface of the large module at one end perpendicular to the translation direction of the support platform 1. The fourth lifting mechanism 10 is used to support the destination and the bottom surface of the large module at the other end perpendicular to the translation direction of the support platform 1.

[0109] S2: A lifting mechanism is installed between the destination and the bottom surface of the support platform 1. The lifting mechanism includes a first lifting mechanism 13 and a second lifting mechanism 12, which are distributed circumferentially along the support platform 1. The second lifting mechanism 12 rises from the Nth through slot to lift the rear edge of the bottom surface of the large module. The first lifting mechanism 13 is located between the destination and the front edge of the bottom surface of the support platform 1, and the first set of first lifting mechanisms 13 rises from the first through slot to lift the front edge of the bottom surface of the large module, so that the large module is lifted to the point of detachment from the support platform 1.

[0110] S3: The large module transfer device begins to move horizontally to withdraw from the large module and the destination. When the first lifting mechanism 13 of the first group is located at the rear end of the first through slot, the second lifting mechanism 13 of the second group rises from the second through slot to lift the front edge of the bottom of the large module. At the same time, the first lifting mechanism 13 of the first group descends below the bottom surface of the support platform 1, so that the large module transfer device can continue to withdraw. This process continues until the Nth lifting mechanism 13 rises from the Nth through slot to lift the front edge of the bottom of the large module, thus completing the withdrawal of the transfer device from the destination and the large module.

[0111] In this embodiment, the two ends of the large module perpendicular to the translation direction of the support platform 1 extend outward relative to the support platform 1.

[0112] Step S2 further includes: setting up a third lifting mechanism 11 between the destination and one end of the large module bottom surface perpendicular to the translation direction of the support platform 1, and setting up a fourth lifting mechanism 10 between the destination and the other end of the large module bottom surface perpendicular to the translation direction of the support platform 1.
