Description

Technical Field

[0001] The present invention relates to the field of large-scale wind tunnel equipment, and in particular to a model assembly room and a transfer system for a large-scale deep-low temperature environment test system. Background Art

[0002] Large-scale cryogenic test systems utilize cryogenic nitrogen as the test medium, operating at temperatures as low as -163°C. Unlike conventional wind tunnels, when models need to be replaced or debugged during cryogenic testing, personnel cannot directly enter the test section, nor can they transfer the cryogenic model directly from the test section to ambient air.

[0003] To improve the efficiency of cryogenic testing, it is often desirable to complete the assembly of models and model components near the main structure of the test system, allowing for quick transfer of the model components to the main structure for testing. Model components include not only the brackets and models that connect them, but also multiple sets of equipment, including control systems. Consequently, they are large and heavy, placing higher demands on stable support, rapid positioning, and efficient assembly during transfer and assembly. However, currently, there are no suitable model assembly rooms for model components in large-scale cryogenic testing systems. Summary of the Invention

[0004] The purpose of the present invention is to provide a model assembly room and transfer system for a large-scale deep-low temperature environment test system, which can stably support large and heavy model components, and can facilitate the assembly and debugging of the model components during the support process. After the assembly is completed, the model components can be transferred out through the top of the model assembly room, filling the technical gap in the existing technology of the lack of a model assembly room suitable for stable support of large model components, and effectively improving the test efficiency and safety.

[0005] The present invention is achieved through the following technical solutions:

[0006] A model assembly room for a large-scale deep-low temperature environment test system includes a model assembly area, the side of which is connected to a model preparation area, a model storage area and a control area. A hoisting hole is provided on the top of the model assembly area. An upper support frame for supporting the upper part of the model assembly and a lower support steel column for supporting the bottom of the model assembly are provided inside the model assembly area.

[0007] In this technical solution, the upper structure of the model component mainly includes multiple sets of equipment such as a control cabinet and a measurement and control component. A model support plate is provided at the bottom, and a model to be tested is provided on the model support plate. The existing preparation of wind tunnel ground models usually only involves the assembly of the model to be tested, and a conventional room can meet the requirements for wind tunnel test preparation, but it cannot meet the high requirements for stable support, rapid positioning, and efficient assembly during the transportation and assembly of large model components. In response to this, this technical solution designs a model assembly room for large model components.

[0008] In this technical solution, the model assembly room includes a model assembly area. Multiple rooms are connected to the side of the model assembly area and are respectively used as a model storage area, a model preparation area, and a control area. Among them, the model storage area is used to place various models to be assembled, the model preparation area is used for multiple tests and debugging work before model assembly, and the control area is used for the deployment control work of the model assembly area.

[0009] In this technical solution, a hoisting hole is provided at the top of the model assembly area. This hoisting hole is used to communicate with the transfer system so that the model component in the environmental air hall can be placed in the model assembly area through the model hoisting device, or after the model component is assembled, it can be hoisted to the environmental air hall through the model hoisting device, thereby realizing the transfer of the model component into or out of the model assembly room.

[0010] In this technical solution, an upper support frame for the model component and a lower support steel column for the model component are also provided inside the model assembly area. The upper support frame for the model component is used to support the upper structure of the model component, that is, the equipment and components above the model support plate of the model component, such as the area where the control cabinet and the measurement and control component are located. In some preferred embodiments, at least one layer of operating platform is further provided on the upper support frame for the model component to debug and assemble the various functional devices of the model component while stably supporting the model component. The lower support steel column for the model component is used to support the bottom surface of the upper structure of the model component and make the bottom surface of the model component a certain distance above the ground to ensure that the model connected to the model support plate is at a height convenient for operation on the ground, such as 1.0 to 1.2 meters.

[0011] In this technical solution, the model assembly room is suitable for the stable support of large model components, the debugging and assembly of the model components during the support process, and after the assembly is completed, the model component can be transferred out of the model assembly room from the top of the model assembly room through the model hoisting device, filling the technical gap in the existing technology of lacking a model assembly room suitable for the stable support of large model components, enabling the staff to complete the efficient and safe assembly of large model components without entering the test section, and improving the test efficiency and safety.

[0012] As a preferred embodiment of the present invention, the upper support frame of the model assembly includes two rows of support columns, each row of support columns includes four support columns, and a reinforced concrete beam is connected between two adjacent support columns. The reinforced concrete beam constitutes a "目"-shaped support layer, and a connecting beam located below the support layer is also connected between the middle two support columns of each row of support columns, wherein the support layer includes a support area and a stabilization area symmetrically arranged on both sides of the support area, and the reinforced concrete beam in the support area is used to support the upper part of the model assembly.

[0013] In this technical solution, the upper support frame of the model assembly has eight support columns, and the eight support columns are divided into two symmetrically arranged columns. A support layer located above and a connecting beam located below are provided on the support columns. Specifically, among the eight support columns, the four support columns located in the same column are connected by reinforced concrete beams. At the same time, two adjacent support columns located in different columns are also connected by reinforced concrete beams, forming a main frame of eight columns and six beams. Among them, the six reinforced concrete beams are arranged in the shape of a "目" when viewed from above or above. The central area of the "目" shape, that is, the rectangular area formed by the two middle support columns of each column and their corresponding reinforced concrete beams, serves as the support area. The upper surface of the reinforced concrete beam is used to support the upper structure of the model assembly.

[0014] In this technical solution, when the model assembly is placed on the reinforced concrete beams of the support area, some of the model assembly equipment, such as the control cabinet, is located above the support area, while other equipment is located below the support area. In some preferred embodiments, a first operating platform is provided around the reinforced concrete beams of the support area. This platform serves as the highest level of the model assembly room, allowing workers to easily set up and operate equipment such as the control cabinet while the model assembly is being placed.

[0015] In this technical solution, the two sides of the support area are stable areas. The stable areas can ensure the stable connection of the overall structure of the support layer through the cooperation of support columns and reinforced concrete beams, greatly improve the bearing capacity, and enable the model components to be stably supported during assembly and lifting.

[0016] In this technical solution, a connecting beam is further provided below the support layer. This connecting beam connects only the two middle support columns in the same row, further enhancing the stability of the central region of the model assembly's upper support frame in the vertical direction. Furthermore, in some preferred embodiments, a second operating platform is provided outside the connecting beam. This second operating platform is located below the first operating platform and is connected to the first operating platform via a steel ladder. This second operating platform facilitates the installation of various equipment located below the support area of the model assembly's upper structure while the model assembly is being placed.

[0017] In this technical solution, by setting the upper support frame of the model component to a structure of six beams and eight columns, it can not only stably support the model component, but also does not block the devices on the upper structure of the model component, facilitating the installation, debugging and detection of the devices of the model component by the staff, and effectively improving the assembly efficiency.

[0018] Furthermore, a first embedded steel plate is arranged on the upper surface of the reinforced concrete beam in the support area. A first adjustment steel plate is welded on the first embedded steel plate. A buffer plate is installed on the first adjustment steel plate. A first buffer rubber block is arranged on the buffer plate.

[0019] In this technical solution, a first embedded steel plate is arranged on the upper surface of the reinforced concrete beam connecting the two middle support columns in each column in the support area. The first embedded steel plate is used for welding the first adjustment steel plate. Since there is a height difference on the surface during the forming process of the reinforced concrete beam, the first adjustment steel plate is used to adjust the height difference to be consistent. A number of through holes are provided on the buffer plate for installing the first buffer rubber block. In some preferred embodiments, the size of the through hole is larger than the size of the first buffer rubber block, so that the first buffer rubber block deforms into the void in the through hole when being extruded.

[0020] In this technical solution, the height of the first buffer rubber block is higher than the height of the buffer plate, and the two together constitute a two-stage buffer structure, greatly reducing the impact on the upper support frame of the model component when the model component is placed on the reinforced concrete beam in the support area, and improving the safety and stability during the hoisting process.

[0021] Furthermore, a guide pin is also installed on the buffer plate, and the guide pin is matched with a guide hole provided on the model component.

[0022] In this technical solution, a guide pin is also arranged on the buffer plate. At the same time, a guide hole matching the guide pin is also arranged on the model component. When the model component is hoisted to the support area, by using the matching of the guide hole and the guide pin, it can play a role in positioning and guiding the large model component during the hoisting process, ensuring the accurate parking of the model component, further improving the accuracy and safety of the large model component during the hoisting process, and improving the hoisting efficiency.

[0023] Furthermore, a second embedded steel plate is arranged on the upper surface of the coupling beam. A second adjustment steel plate is welded on the second embedded steel plate. A guide sleeve is installed on the second adjustment steel plate. The guide sleeves on the two coupling beams form a limiting area, and the limiting area is used to limit the model component to move only in the vertical direction.

[0024] In this technical solution, the coupling beam not only plays a connecting role, but also can, through the guide sleeves installed thereon, limit the model components during the hoisting process, and further improve the positioning accuracy during hoisting in combination with the guide pins. Specifically, a second embedded steel plate is provided on the coupling beam, and a second adjustment steel plate is welded to the second embedded steel plate. The setting method of the second embedded steel plate and the second adjustment steel plate is similar to that of the first embedded steel plate and the first adjustment steel plate, and the second adjustment steel plate is also used to adjust the elevation difference. At the same time, a guide sleeve is also provided on the second adjustment steel plate. The guide sleeve can have various setting structures, but no matter what structure it is, the guide sleeves on the two coupling beams can form a limiting area. When the model components enter the limiting area, the inner sides of the respective guide sleeves contact the outer walls of the model components, enabling the model components to move only in the vertical direction, effectively improving the stability and safety of the model components during the hoisting process.

[0025] In this technical solution, the guide sleeves are only provided on the coupling beams, so the limiting area formed by them only acts on the two faces of the model components close to the coupling beams. Therefore, during the guiding and positioning process, more areas can be exposed to facilitate the staff to detect and debug the various equipment of the model components.

[0026] Furthermore, the number of lower support steel columns of the model components is 4. There are no connecting components between any two lower support steel columns of the model components. A third adjustment steel plate is provided at the top of the lower support steel columns of the model components, and a second buffer rubber block is installed on the third adjustment steel plate.

[0027] In this technical solution, there are 4 lower support steel columns for the model components, and the 4 support steel columns support the bottom surface of the model components. Preferably, the 4 support steel columns are symmetrically arranged with respect to the axis of the model assembly area. A third adjustment steel plate is provided at the top of the 4 support steel columns. While the third adjustment steel plate is used to adjust the elevation difference, through holes are provided for installing the second buffer rubber block, so as to buffer the impact when the model components are hoisted to the model assembly area and improve the safety and stability of hoisting.

[0028] In this technical solution, different from the support columns of the upper support frame being connected by reinforced concrete beams, the 4 lower support steel columns of the model components are not connected to each other by reinforced concrete beams or other connecting components. The 4 support steel columns are independent of each other, thus reducing the interference and influence of the connecting components on the model components and facilitating the staff to install and debug the lower half of the model components.

[0029] Furthermore, the bottom surface of the model assembly area is communicated with a model loading area. The lower support steel columns of the model components are arranged in the model loading area, and the tops of the lower support steel columns of the model components penetrate the top surface of the model loading area and extend into the model assembly area.

[0030] In this technical solution, the model loading area is arranged at the bottom of the model assembly area, that is, the model loading area is located on the first basement floor, and the top of the model loading area is communicated with the model assembly area. In some preferred embodiments, the top plate of the model loading area is provided with first and second reserved holes along the transverse axis of the model assembly area. Among them, the positions of the first and second reserved holes are configured such that when the model components are placed in the model assembly area, the first reserved hole is located below the model, and the second reserved hole is for the model support plate to pass through.

[0031] In this technical solution, by arranging the model loading area below the model assembly area, the problem that the model support plate needs to sink below the ground when the model components are parked is solved, and it is also convenient to perform loading tests on the model, such as operations like hanging weights.

[0032] The present invention also provides a transfer system for a large-scale cryogenic environment test system. The transfer system includes an environmental air hall. At least one of the aforementioned model assembly rooms is arranged on the bottom surface of the environmental air hall. The model assembly room is communicated with the environmental air hall through the hoisting hole. A track is also arranged in the environmental air hall. A model hoisting device is arranged on the track. The model hoisting device is used to move along the track and transfer the model components between the environmental air hall and the test section of the main structure of the large-scale cryogenic environment test system.

[0033] In this technical solution, the transfer system is a two-layer structure. Among them, the upper layer of the transfer system is the area for the model hoisting device to move, mainly including the environmental air hall. The lower layer of the transfer system is the area for the assembly and debugging of the model components, mainly including at least one model assembly room.

[0034] In this technical solution, the environmental air hall is communicated with the outside to move the model hoisting device into or out of the transfer system along the track. In some preferred embodiments, a detachable sealing door is arranged on the south outer wall of the upper layer of the transfer system. After removing the detachable sealing door, the model hoisting device and the hatch cover hoisting device in the resident room can run along the track to the outdoor steel frame. At the same time, the environmental air hall is also indirectly communicated with the test section of the main structure of the test system, so as to allow the model components assembled in the environmental air hall to be transferred to the test section for testing through the model hoisting device, and also allow the model components after the test to be transferred to the environmental air hall through the model hoisting device.

[0035] In some embodiments, the main structure can adopt an existing wind tunnel structure, which mainly includes parts such as a diffuser section, a stabilization section, a contraction section, and a test section. Among them, the test section is arranged in the resident room. In some preferred embodiments, the main structure adopts a return flow structure in the prior art.

[0036] In this technical solution, a track is also provided on the upper layer of the transfer system. The track can be laid on the floor slab of the upper layer of the transfer system or on the ceiling of the upper layer of the transfer system. In some preferred embodiments, considering the weight of the model components and the model hoisting device, the track is laid on the floor slab of the upper layer of the transfer system. The model hoisting device provided on the track can adopt an existing gantry structure to realize the hoisting of the model components. The model hoisting device can move along the track on the upper layer of the transfer system.

[0037] In this technical solution, each model assembly room is connected to the upper environmental air hall through a hoisting hole, and the model hoisting device can move the model components into or out of the model assembly room through the hoisting hole. Inside the model assembly room, the staff can assemble, debug, repair, etc. the model components at normal temperature. After the operation is completed, they can be temporarily stored in the model assembly room or transported to the test section by using the model hoisting device according to the requirements.

[0038] In this technical solution, by setting up the transfer system, whether before or during the test in the main structure, the assembly of the model components can be completed in the model assembly room. After the assembly is completed, the model components can be stored in the model assembly room for standby, or hoisted to the upper layer of the transfer system, then moved above the test section, and finally put into the test section. This not only improves the operation safety but also greatly improves the test efficiency.

[0039] Further, the environmental air hall is connected to a dry air hall through a wet-dry conversion gate, and the dry air hall is connected to the test section; during the operation of the system, the dew point of the air in the wet-dry conversion gate and the dry air hall is lower than -60°C, and the carbon dioxide content is lower than 10 ppm.

[0040] In this technical solution, the upper layer of the transfer system is an area for the movement of the model hoisting device, which includes a dry air hall, a wet-dry conversion gate, and an environmental air hall connected in sequence. Among them, the environmental air hall is connected to the outside, and the dry air hall is connected to the test section. The wet-dry conversion gate is used to separate the environmental air hall and the dry air hall. In some embodiments, a first gate is provided between the wet-dry conversion gate and the environmental air hall, and a second gate is provided between the wet-dry conversion gate and the dry air hall. The first gate and the second gate are used to block the air flow between the environmental air hall and the dry air hall, and at the same time, the wet-dry conversion gate is used as a transition area to adjust the humidity of the air.

[0041] In this technical solution, during the operation of the system, the dew point of the air in the wet-dry conversion gate and the drying air hall is lower than -60°C, and the carbon dioxide content is lower than 10 ppm. Therefore, when the model component to be debugged is lifted out of the test section, the model component enters the wet-dry conversion gate through the drying air hall along the track and warms up to room temperature, and then enters the ambient air hall, which can ensure that the surface of the low-temperature model component removed from the test section will not freeze / frost during the transfer process. Similarly, by using the transition of the wet-dry conversion gate, the model component in the ambient air hall enters the wet-dry conversion gate to remove moisture and carbon dioxide, and then enters the drying air hall, ensuring that external moisture and carbon dioxide do not enter the drying air hall during the transfer process, thereby further improving the accuracy and safety of the test.

[0042] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0043] 1. The model assembly room of the present invention is suitable for the stable support of large model components. During the support process, the debugging and assembly of the model components can be carried out, and after the assembly is completed, the model components can be transferred out of the model assembly room from the top of the model assembly room through the model lifting device, filling the technical gap in the prior art that lacks a model assembly room suitable for the stable support of large model components, enabling the staff to complete the efficient and safe assembly of large model components without entering the test section, and improving the test efficiency and safety;

[0044] 2. By setting the upper support frame of the model component of the present invention to a structure of six beams and eight columns, it can not only form a stable support for the model component, but also does not block the equipment of the upper structure of the model component, facilitating the installation, debugging and detection of the equipment of the model component by the staff, and effectively improving the assembly efficiency;

[0045] 3. In the present invention, the height of the first buffer rubber block is higher than that of the buffer plate, and the two together constitute a two-stage buffer structure, greatly reducing the impact on the upper support frame of the model component when the model component is placed on the reinforced concrete beam in the support area, and improving the safety and stability during the lifting process;

[0046] 4. By using the matching of the guiding hole and the guiding pin, the present invention can play a role in positioning and guiding large model components during the lifting process, ensuring the accurate parking of the model components, further improving the accuracy and safety of large model components during the lifting process, and improving the lifting efficiency;

[0047] 5. The coupling beam of the present invention not only plays a connecting role, but also can limit the model components during the hoisting process through the guide sleeves installed thereon. In combination with the guide pins, it further improves the positioning accuracy during the hoisting process. At the same time, since the guide sleeves are only provided on the coupling beam, the limiting area formed by the guide sleeves only acts on the two faces of the model components close to the coupling beam. Therefore, during the guiding and positioning process, more areas can be exposed, facilitating the detection and debugging of various devices of the model components by the staff;

[0048] 6. By arranging the model loading area below the model assembly area, the present invention not only solves the problem that the model support plate needs to sink below the ground when the model components are parked, but also facilitates the loading test of the model, such as operations like hanging weights;

[0049] 7. By setting up a transfer system, whether before or during the test within the main structure, the assembly of the model components can be completed within the model assembly room. After completion of the assembly, the model components can either be stored in the model assembly room for standby or hoisted to the upper layer of the transfer system, then moved above the test section, and finally placed into the test section. This not only improves the operation safety but also greatly improves the test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0062] To make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0063] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "high", "low", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present invention.

[0064] Embodiment 1:

[0065] As Figures 1 to 4 shown, a model assembly room for a large-scale deep low-temperature environment test system includes a model assembly area 802. The side of the model assembly area 802 is connected to a model preparation area 801, a model storage area 804, and a control area 803. A hoisting hole is provided at the top of the model assembly area 802. Inside the model assembly area 802, there is a model component upper support frame 821 for supporting the upper part of the model component 330 and a model component lower support steel column 822 for supporting the bottom of the model component 330.

[0066] In one or more embodiments, as Figure 2As shown, the model preparation area, the model assembly area, and the control area are arranged in series. At the same time, the control area and the model storage area are arranged side by side longitudinally along the model assembly area to reasonably utilize the space of the model assembly room and improve the model assembly efficiency.

[0067] In one or more embodiments, the size of the hoisting hole is 13.4 (length) × 7.1 m (width).

[0068] In some preferred embodiments, the upper support frame 821 of the model component includes two columns of support columns. Each column of support columns includes four support columns, and a reinforced concrete beam is connected between adjacent two support columns. As Figure 4 shown, the reinforced concrete beams form a "mesh" - shaped support layer. A connecting beam located below the support layer is also connected between the middle two support columns of each column of support columns. Among them, the support layer includes a support area and stable areas symmetrically arranged on both sides of the support area. The reinforced concrete beams in the support area are used to support the upper part of the model component 330.

[0069] As Figure 1 and Figure 4 shown, a first operation platform 8216 is arranged outside the reinforced concrete beam in the support area. The first operation platform is the top layer of the model assembly room, that is, the third layer. When the reinforced concrete beam in the support area supports the model component, some equipment of the model component, such as the control cabinet, is located above the support area, and the staff can detect and debug the part of the model component located above the support area on the first operation platform. At the same time, a second operation platform 8221 is arranged outside the connecting beam. The second operation platform 8221 is the second layer of the model assembly room. Since the connecting beam only connects the middle two support columns of the same column, the middle and lower parts of the model component can be maximally exposed, facilitating the staff to detect and debug the equipment related to the model component located below the support area and above the connecting beam on the second operation platform. The ground of the model assembly room is the first layer. When assembling the model component, the top elevation of the upper support frame of the model component and the top elevation of the lower support steel column of the model component meet the requirement of ensuring that the center of the model at the bottom of the model component is at a reasonable height relative to the indoor ground elevation, such as 1.0 to 1.2 meters, preferably 1.1 meters, so as to facilitate the staff to load and debug the model.

[0070] In one or more embodiments, a first steel ladder 8217 is arranged between the upper support frame of the model component and the ground.

[0071] Embodiment 2:

[0072] On the basis of Embodiment 1, as Figure 1 and Figure 4As shown, a first embedded steel plate 8211 is provided on the upper surface of the reinforced concrete beam in the support area. A first adjustment steel plate 8212 is welded to the first embedded steel plate 8211. A buffer plate 8213 is installed on the first adjustment steel plate 8212. A first buffer rubber block 8214 is provided on the buffer plate 8213.

[0073] In this embodiment, the first embedded steel plate is used to weld the first adjustment steel plate. Since there is a height difference on the surface of the reinforced concrete beam during the forming process, the first adjustment steel plate is used to adjust the height difference to be consistent. A number of through holes are provided in the buffer plate for installing the first buffer rubber block. In some preferred embodiments, the size of the through holes is larger than the size of the first buffer rubber block, so that the first buffer rubber block deforms into the gap in the through holes when being squeezed. In one or more embodiments, the gap width between the through holes and the first buffer rubber block is 20 - 50 mm.

[0074] In one or more embodiments, the first buffer rubber blocks are symmetrically arranged with respect to the axis of the model assembly area. In some embodiments, the number of the first buffer rubber blocks is 4 - 10. In some embodiments, the height difference between the top surface of the first buffer rubber block and the top surface of the buffer plate is less than the elastic compression amount of the first buffer rubber block. Preferably, the height difference between the top surface of the first buffer rubber block and the top surface of the buffer plate is 8 - 20 mm.

[0075] In some preferred embodiments, a guide pin 8215 is further installed on the buffer plate 8213, and the guide pin 8215 is matched with a guide hole provided on the model assembly 330.

[0076] In some preferred embodiments, as Figure 4 shown, the number of the guide pins provided is 2. The two guide pins are close to the transverse axis of the model assembly area and are centrally symmetrically arranged with respect to the center of the model assembly area.

[0077] In some preferred embodiments, a second embedded steel plate 8218 is provided on the upper surface of the coupling beam. A second adjustment steel plate 8219 is welded to the second embedded steel plate 8218. A guide sleeve 8220 is installed on the second adjustment steel plate 8219. The guide sleeves 8220 on the two coupling beams form a limiting area, and the limiting area is used to limit the model assembly 330 to move only in the vertical direction.

[0078] In this embodiment, the coupling beam not only serves as a connection, but also can limit the model components during the hoisting process through the guide sleeves installed thereon, and further improve the positioning accuracy during the hoisting process in combination with the guide pins. In this embodiment, the guide sleeves are only provided on the coupling beam, so the limited area formed by them only acts on the two faces of the model components close to the coupling beam, so that more areas can be exposed during the guiding and positioning processes, facilitating the staff to detect and debug the various devices of the model components.

[0079] In some preferred embodiments, such as Figure 3 shown, one guide sleeve is provided on each coupling beam, and the guide sleeves are all located on the transverse axis of the model assembly area.

[0082] In this embodiment, a third adjustment steel plate is provided at the top of the 4 support steel columns. While the third adjustment steel plate is used to adjust the elevation difference, through holes are provided for installing the second buffer rubber block, so as to buffer the impact when the model component is hoisted to the model assembly area, and improve the safety and stability of the hoisting.

[0083] In one or more embodiments, the first buffer rubber block is made of rubber and the second buffer rubber block is made of polytetrafluoroethylene.

[0086] In some preferred embodiments, the top plate of the model loading area is provided with a first and a second reserved hole along the transverse axis of the model assembly area. Among them, the positions of the first and second reserved holes are configured such that when the model component is placed in the model assembly area, the first reserved hole is located below the model, and the second reserved hole is for the model support plate to pass through.

[0087] In one or more embodiments, cover plates are provided on the first and second reserved holes to open or close the reserved holes as required. In one or more embodiments, a second steel ladder is also provided between the model assembly area and the model loading area for staff to move between the two areas.

[0088] In this embodiment, the model loading area 805 is on the first basement floor.

The model hoisting device 326 is used to move along the track 328 and transfer the model components 330 between the environmental air hall 321 and the test section of the main structure 1 of the large-scale cryogenic environment test system.

[0091] In some preferred embodiments, the environmental air hall 321 is connected to a dry air hall 323 through a dry-wet conversion gate 322, and the dry air hall 323 is connected to the test section;

[0092] During the operation of the system, the dew point of the air in the dry-wet conversion gate 322 and the dry air hall 323 is lower than -60°C, and the carbon dioxide content is lower than 10 ppm.

In one or more embodiments, the first gate provided between the dry-wet conversion gate and the environmental air hall can be turned up and opened towards the environmental air hall side. Similarly, the second gate provided between the dry-wet conversion gate and the dry air hall can be turned up and opened towards the dry air hall side.

[0095] In one or more embodiments, the top surface of the track is flush with the floor of the upper layer of the transfer system.

[0096] In one or more embodiments, a plurality of model assembly rooms and low-temperature model transformation rooms may be provided on the lower layer of the transfer system. In some embodiments, a model access control room is further provided on the lower layer of the transfer system to control the opening and closing of the first and second gates and the humidity of the air in the dry-wet conversion gate.

[0097] In some preferred embodiments, as Figure 5 shown, an outdoor steel frame 18 is further provided outside the transfer system 3, and the track 328 extends to the upper surface of the outdoor steel frame 18.

[0098] In some preferred embodiments, it further includes a chamber door hoisting device 327 that can move along the track 328. The chamber door hoisting device 327 is used to hoist the chamber door to close or open the chamber door 1011 between the test section and the dry air hall 323. By providing the chamber door hoisting device, the chamber door can be moved more quickly and safely, and the chamber door can be opened or closed, further improving the test efficiency.

[0099] In this embodiment, the transfer system can be used to hoist model components between the model assembly room, the low-temperature model transformation room, and the test section. The model assembly room connected to the ambient air hall allows staff to operate the model components at normal temperature before and during the test, while the low-temperature model transformation room connected to the dry air hall allows staff to debug the model components at low temperature during the operation of the system. This not only improves the operation safety but also greatly improves the test efficiency, and the model can be debugged in a timely manner during the test, effectively improving the test effect.

[0100] In addition, by maintaining low dew point and carbon dioxide content in the dry-wet conversion gate, the dry air hall, and the low-temperature model transformation room, it can be ensured that the surface of the low-temperature model components will not freeze / frost during transportation.
