Description

Technical Field

[0001] The present invention relates to the technical field of environmental testing, and particularly to a panel structure of a test equipment and a fixed connection structure between the panel and a workshop. Background Art

[0002] To better meet the test requirements for the durability, life, aging verification, etc. of super-large specimens under real natural environmental conditions, and to provide a test basis for the further performance analysis, modification, and optimization design of super-large specimens, currently, super-large test equipment is used to simulate natural environments such as high temperature, low temperature, and humidity to achieve temperature and humidity simulation tests.

[0003] It should be noted that a super-large specimen can be a specimen with large external dimensions, or a batch of specimens composed of multiple specimens with a relatively large volume. Among the three dimensions of length, width, and height of a super-large specimen, two of the dimensions exceed 13 m. A super-large test equipment refers to a test equipment in which the three dimensions of length, width, and height of the test chamber all exceed 15 m.

[0004] For super-large test equipment, according to the test requirements, it is necessary to simulate high and low temperature and humid environments inside. At this time, due to the excessively large volume of the chamber body (i.e., the panel chamber body, simply referred to as the chamber body) of the super-large test equipment and the large temperature difference between the inside and outside of the chamber body, the chamber body of the super-large test equipment is extremely prone to local deformation problems, which affect the overall sealing performance of the chamber body and further affect the reliable progress of the test.

[0005] Therefore, there is an urgent need to develop a technology at present that can solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a panel structure of a test equipment and a fixed connection structure between the panel and a workshop in view of the technical defects existing in the prior art.

[0007] To this end, the present invention provides a panel structure of a test equipment, which includes at least one panel unit in the shape of a hexahedron;

[0008] The panel unit is a hollow sealed housing;

[0009] On one side of the panel unit facing the inner cavity of the test equipment chamber, an inner panel is provided, and on the other side away from the inner cavity of the test equipment chamber, an outer panel is provided;

[0010] The inner panel and the outer panel are distributed at intervals;

[0011] The inner cavity of the panel unit is provided with a polyurethane foam layer;

[0012] Among the remaining sides of the panel unit except for the two sides where the inner panel and the outer panel are provided, at least two sides are provided with inner concave portions and / or outer convex portions;

[0013] The lower sides of the concave part and the convex part are provided with folding edges protruding downward;

[0014] Embedded hook locks are respectively arranged at the central positions of the concave part and the convex part;

[0015] The two embedded hook locks are located in the inner cavity of the library board unit;

[0016] A plurality of planting nails are arranged on one side of the inner plate facing the outer plate;

[0017] A limiting baffle is arranged at one end of each planting nail far away from the inner plate.

[0018] In addition, the present invention also provides a fixed connection structure between the library board and the workshop, which includes a workshop top beam;

[0019] The workshop top beam is connected to one library board unit in the library board structure of the test equipment as described above.

[0020] In addition, the present invention also provides another fixed connection structure between the library board and the workshop, which includes a workshop side beam;

[0021] The workshop side beam is connected to one side of two library board units included in the library board structure of the test equipment as described above.

[0022] As can be seen from the technical solutions provided by the present invention above, compared with the prior art, the present invention provides a library board structure of a test equipment and a fixed connection structure between the library board and the workshop. The structural design is scientific and is applied to super-large test equipment. When it is necessary to simulate high and low temperature and humid environment inside the super-large test equipment, it can avoid the problem of local deformation of the library body of the super-large test equipment, ensure the overall sealing performance of the library body, and further ensure the reliable progress of the test, which has great practical significance.

[0023] In addition, by applying the present invention, it is also beneficial to solve the problems that are likely to occur during the construction and use of the library body of the test equipment (i.e., the library board cabin of the test equipment that needs to simulate high and low temperature and humid environment), such as local deformation of the library board, peeling of the library board, and insufficient overall building strength of the library body.

[0042] Embodiment 1.

[0043] See Figures 1 to 4 , the present invention provides a panel structure for a test device, which is applied to the chamber of the test device (i.e., the panel cabin of the test device that needs to simulate high and low temperature and humid environment), and it includes at least one panel unit 1 in the shape of a hexahedron;

[0044] The panel unit 1 is a hollow sealed housing;

[0045] The panel unit 1 is provided with an inner panel 12 on one side facing the inner cavity of the chamber of the test device, and an outer panel 13 on the other side away from the inner cavity of the chamber of the test device;

[0046] The inner panel 12 and the outer panel 13 are spaced apart;

[0047] It should be noted that the inner panel 12 is located inside the chamber of the test device; the outer panel 13 is located outside the chamber of the test device;

[0048] The inner cavity of the panel unit 1 is provided with a polyurethane foam layer 14;

[0049] Among the remaining sides of the library board unit 1 except for the two sides where the inner board and the outer board are provided, at least two sides are provided with concave portions 21 and / or convex portions 20;

[0050] At the lower side of the concave portion 21 and the convex portion 20, a folded edge 16 is provided protruding downward;

[0051] It should be noted that, for example, referring to Figure 1 , Figure 2 As shown, for a library board unit 1 located at the edge position of a wall of the library body, concave portions 21 and convex portions 20 are respectively provided on its left and right sides, and a concave portion 21 is provided on its front side, and folded edges 16 are provided on the lower sides of the two concave portions 21 and the lower side of the convex portion 20. Another example, referring to Figure 9 , Figure 10 As shown, for a library board unit 1 located at the center position of a wall of the library body, concave portions 21 and convex portions 20 can be respectively provided on the left and right sides of the library board unit 1 and concave portions 21 and convex portions 20 are respectively provided on the front and rear sides.

[0052] At the center positions of the concave portion 21 and the convex portion 20, embedded hook locks 15 are respectively provided;

[0053] The two embedded hook locks 15 are located in the inner cavity of the library board unit 1;

[0054] On the side of the inner board 12 facing the outer board 13, a plurality of (for example, two) planting nails 17 are provided;

[0055] At the end of each planting nail 17 away from the inner board 12, a limiting baffle 19 is provided.

[0056] In the present invention, specifically, for the library board unit 1, a layer of high-temperature resistant glue 18 (specifically, a high-temperature resistant adhesive) is coated on the side of the inner board 12 facing the outer board 13 (i.e., the foaming surface, also the inner side surface).

[0057] It should be noted that the high-temperature resistant glue 18 is a glue whose bonding performance does not fail in a high-temperature environment (such as +120 °C), and is used to firmly bond the inner board 12 and the polyurethane foaming layer 14 together. As long as the glue meets this requirement, it can be used, and it is an existing conventional glue, which will not be elaborated here.

[0058] In the present invention, specifically, for the library board unit 1, the central axis of the folded edge 16 is perpendicular to the central axis of the embedded hook lock 15.

[0059] In the present invention, specifically, for the library board unit 1, the central axes of the two embedded hook locks 15 are located on the same straight line.

[0060] In the present invention, specifically, the polyurethane foam layer 14 fills the remaining voids in the inner cavity of the panel unit 1 (in the inner cavity of the panel unit 1, the remaining space except for the space occupied by the embedded hook lock 15, the high-temperature resistant adhesive 18, the dowel 17, and the limit baffle 19, that is, the remaining voids).

[0061] It should be noted that for the present invention, the function of the polyurethane foam layer 14 is heat preservation and cold bridge breaking, preventing heat transfer between the internal and external environments of the test chamber (i.e., the library body for installing test equipment), so as to ensure the heat preservation function of the test chamber.

[0062] Specifically, the embedded hook lock 15 is divided into two types: male head and female head. The convex part 20 and the concave part 21 of the library body are respectively installed with the male head type embedded hook lock 15 and the female head type embedded hook lock 15. When the convex part and the concave part of two panel units are spliced, rotate the nut in the male head type embedded hook lock 15 so that the hook on it hangs on the female head type embedded hook lock 15 to realize the connection at the splicing place of the two panel units.

[0063] In the present invention, specifically, the embedded hook lock 15 is a mature connecting piece in the prior art. For example, a Carson eccentric buckle with the model number YL-1168 produced by Yuhuan Yulong Refrigeration Machinery Factory can be used, and this component can be used for connection and fixation at the joint when the panel units are spliced.

[0064] In the present invention, specifically, the inner plate 12 can specifically be a stainless steel plate with a thickness of 1.5 mm. Since the inner plate 12 is located inside the test chamber (i.e., the library body for installing test equipment), and the internal environment of the test chamber involves a high-temperature and high-humidity environment, using a stainless steel plate can prevent rusting.

[0065] Specifically, the outer plate 13 can specifically be a cold-rolled steel plate with a thickness of 1.5 mm, and the surface of the steel plate is spray-painted, which can ensure the anti-static performance of the outer plate and the overall aesthetics of the test chamber.

[0066] In the present invention, specifically, on the inner side of the inner plate 12 facing the outer plate 13, the dowel 17 is welded by a percussion welding process, and at the same time, a high-temperature resistant adhesive 18 is applied to the inner side of the inner plate 12 to increase the adhesion of this surface.

[0067] Specifically, the limit baffle 19 is installed on the dowel 17 by bolts.

[0068] Specifically, the limit baffle 19 can be made of an epoxy resin board with good heat insulation and strength.

[0069] It should be noted that for each library board unit 1, after the foaming process of the polyurethane foam layer 14 inside it is completed, the surface of the high-temperature resistant glue 18 in contact with the polyurethane foam layer 14 can form a whole surface of high-strength area. At the same time, by embedding the limit baffle 19 inside the polyurethane foam layer 14, it further provides a pulling force for the inner board 12 to prevent shelling, which can greatly avoid local deformation caused by the thermal expansion and contraction of the inner board 12, and avoid the situation that the inner board 12 is separated from the heat preservation layer (i.e., the polyurethane foam layer 14).

[0070] It should be noted that shelling prevention is a phenomenon, and the root cause is the deformation of the library body. For example, when high and low temperature tests are carried out in the test chamber, it is very easy for the inner board 12 to bulge locally, which will then cause the inner board 12 to be separated from the polyurethane foam layer 14.

[0071] It should be noted that for the present invention, the reason why it can provide a pulling force for the inner board 12 to prevent shelling is that, firstly, by coating the high-temperature resistant glue 18 on the surface of the inner board 14, the connection force between the inner board 12 and the polyurethane foam layer 14 is increased, so that it is easier to form a whole and is not easily pulled apart; secondly, because the stud 17 is welded on the inner board 12, and the top of the stud 17 fixes the limit baffle 19, which further increases the connection force between the inner board 12 and the polyurethane foam layer 14.

[0072] In the present invention, specifically, when the library board structure includes multiple library board units 1, for any two library board units 1 that need to be connected, the convex part 20 on one library board unit 1 is spliced with the concave part 21 on the other library board unit 1, and a high and low temperature resistant sealing silica gel is applied to the contact surface between the two for sealing and bonding; therefore, the sealing performance of the joint of the two library board units can be guaranteed.

[0073] When three library board units 1 need to be spliced, the convex part 20 on the first library board unit 1 is spliced with the concave part 21 on the second library board unit 1, and the concave part 2 on the first library board unit 1 is spliced with the convex part 20 on the third library board unit 1.

[0074] In the present invention, specifically, when the library board structure includes multiple library board units 1, for any two library board units 1 that need to be connected, the joint of the outer boards 13 of the two library board units is covered (for example, welded) with an outer mounting plate 3.

[0075] In the present invention, specifically, when the library board structure includes multiple library board units 1, for any two library board units 1 that need to be spliced, the folding edges 16 on the convex part 20 of one library board unit 1 are seamlessly welded to the folding edges 16 on the concave part 21 of the other library board unit 1.

[0076] In the present invention, specifically, when the library board structure includes multiple library board units 1, for any two library board units 1 that need to be spliced, the embedded hook lock 15 on the convex part 20 of one library board unit 1 is connected to the embedded hook lock 15 on the concave part 21 of the other library board unit 1.

[0077] It should be noted that for the present invention, for any two library board units 1 that need to be spliced, when assembling the two library board units 1, the locking and docking operation of the embedded hook locks 15 on them is carried out, thereby increasing the overall connection reliability of the two assembled library board units 1.

[0078] In the present invention, specifically, when the library board structure includes multiple library board units 1, for any two library board units 1 that need to be spliced, the folding edge 16 on the convex part 20 of one library board unit 1 and the folding edge 16 on the concave part 21 of the other library board unit 1 are seamlessly welded in full by adopting the TIG (Tungsten Inert Gas Welding, also known as non - consumable electrode inert gas shielded arc welding) welding method.

[0079] It should be noted that for the present invention, for any two library board units 1 that need to be spliced, the telescopic folding edges 16 at the inner plates 12 of the two library board units are subjected to TIG seamless full welding. On the one hand, the connection between the two library board units is made firm, effectively preventing the problem of expansion and cracking at high and low temperatures. On the other hand, after full welding, a telescopic joint can be formed here, which can effectively eliminate the local stress caused by the thermal expansion and contraction deformation of the inner plate of the library board unit, thereby avoiding the occurrence of local deformation phenomena.

[0080] It should be noted that the telescopic joint is the recessed part at the splicing place of two library board units, and its main function is to release the stress of the inner plate of the library board unit and prevent the library board unit from undergoing plastic deformation.

[0081] The fundamental structure of the telescopic joint is a slope obtained by bending the sheet metal at the four - week edge of the library board unit. It is named the telescopic joint based on the function it realizes; when adjacent two library board units are subjected to full welding operation, the inner plate has welding stress that needs to be released, and the telescopic folding edge 16 obtained by sheet metal bending has both a certain strength and a certain adjustable amount, which can play a role in releasing the stress of the inner plate during welding, thereby avoiding the deformation of the library board unit and the entire library body.

[0082] Embodiment 2.

[0083] Based on the above - mentioned library board structure provided by the present invention, refer to Figure 5 、 Figure 6As shown in the figure, the present invention also provides a fixed connection structure between the library board and the workshop, specifically a fixed connection structure between the library board and the top beam of the workshop, which is applied to the library body (i.e., the library board cabin) of the test equipment. The library body of the test equipment is located in a workshop;

[0084] The fixed connection structure between the library board and the workshop includes the top beam 4 of the workshop;

[0085] The top beam 4 of the workshop is connected to a library board unit 1 in the library board structure of the test equipment as described above;

[0086] In the present invention, specifically in implementation, regarding the connection between the top beam 4 of the workshop and the library board unit 1 in the library board structure of the test equipment, the specific structural design is as follows:

[0087] The top beam 4 of the workshop is connected to one end of the turnbuckle 6 through the second screw rod 8;

[0088] The other end of the turnbuckle 6 is connected to one end of the first screw rod 7;

[0089] The other end of the first screw rod 7 is connected to a library board unit 1 in the library board structure of the test equipment;

[0090] A heat preservation sleeve 9 is installed outside the part of the first screw rod 7 located between the turnbuckle 6 and the outer board 13 of the library board unit 1.

[0091] Specifically in implementation, after the upper end of the second screw rod 8 passes through the first through hole reserved on the top beam 4 of the workshop, it is threadedly and fixedly connected to a nut 2;

[0092] The lower end of the second screw rod 8 is threadedly and fixedly connected to the threaded hole reserved on the upper end of the turnbuckle 6;

[0093] Specifically in implementation, the upper end of the first screw rod 7 is threadedly and fixedly connected to the threaded hole reserved on the lower end of the turnbuckle 6;

[0094] The lower end of the first screw rod 7 passes through the second through hole reserved on the library board unit 1 and is threadedly and fixedly connected to two nuts 2.

[0095] Furthermore, the first screw rod 7 is threadedly and fixedly connected to two nuts 2, and these two nuts 2 are distributed on the inner and outer sides of the library board unit 1;

[0096] Among them, one nut 2 is connected to the lower end of the first screw rod 7 and is in tight contact with the outer surface of the inner board 12 of the library board unit 1. The other nut 2 is connected to the middle section of the first screw rod 7 and is in tight contact with the outer surface of the outer board 13 of the library board unit 1. Therefore, through the two nuts 2 distributed inside and outside, the first screw rod 7 can be reliably fixedly connected to the inner and outer sides of the library board unit 1.

[0097] Specifically, the heat-insulating sleeve 9 is sleeved over and covers the outer side of the portion of the first lead screw 7 located between the turnbuckle 6 and the outer plate 13 of the storage panel unit 1.

[0098] It should be noted that the heat-insulating sleeve 9 is installed on the outer surface of the first lead screw 7 and covers and obscures all the visible lengths of the first lead screw 7. Since the visible length area of the first lead screw 7 between the outer plate 13 and the turnbuckle 6 is completely wrapped inside the heat-insulating sleeve 9, therefore, for the storage body (i.e., the storage panel cabin) of a test equipment, heat insulation from inside the storage to outside can be achieved.

[0099] Specifically, the overall shape of the factory building top beam 4 is in the shape of a "work" character and is placed horizontally.

[0100] Embodiment 3.

[0101] Based on the storage panel structure provided by the present invention as described above, referring to Figure 7 、 Figure 8 as shown, the present invention further provides a fixed connection structure between the storage panel and the factory building, specifically a fixed connection structure between the storage panel and the side beam of the factory building, which is applied to the storage body (i.e., the storage panel cabin) of a test equipment, and the storage body of this test equipment is located in a factory building;

[0102] The fixed connection structure between the storage panel and the factory building includes a factory building side beam 5;

[0103] The factory building side beam 5 is connected to one side of the two storage panel units 1 included in the storage panel structure of the test equipment as described above;

[0104] In the present invention, specifically, the two storage panel units 1 in the storage panel structure of the test equipment are stacked vertically.

[0105] In the present invention, specifically, regarding the connection between the factory building side beam 5 and the two storage panel units 1 in the storage panel structure of the test equipment, the specific structural design is as follows:

[0106] The two outer plates 13 of the two storage panel units 1 in the storage panel structure of the test equipment are simultaneously connected to one side of the fixing plate 11;

[0107] The other side of the fixing plate 11 is connected to the first contact surface on the connection bracket 10;

[0108] The second contact surface on the connection bracket 10 is connected to one side (specifically the upper side) of the factory building side beam 5;

[0109] The first contact surface and the second contact surface on the connection bracket 10 are two perpendicular intersecting planes;

[0110] Specifically, the other side of the fixing plate 11 is welded to the first contact surface on the connection bracket 10;

[0111] The second contact surface on the connecting bracket 10 is welded to one side (specifically, the upper side) of the factory building side beam 5.

[0112] Specifically, the fixing plate 11 is riveted and fixed to the two outer plates 13 in the two storage board units 1 included in the storage board structure of the test equipment;

[0113] Furthermore, the fixing plate 11 is riveted and fixed to the two outer plates 13 in the two storage board units 1 included in the storage board structure through four blind rivets.

[0114] Specifically, the overall shape of the factory building side beam 5 is in the shape of "I".

[0115] It should be noted that the outer mounting plate 3 is not installed in the area covered by the fixing plate 11 to ensure the close fit between the fixing plate 11 and the outer plate 13. After the two storage board units 1 are assembled and leveled, the connecting bracket 10 is positioned and welded according to the actual distance between the outer plate 13 and the factory building side beam 5, and the connecting bracket 10 is welded to the fixing plate 11 and the factory building side beam 5 respectively.

[0116] Embodiment 4.

[0117] Based on the above storage board structure provided by the present invention, the present invention also provides a storage body, as the storage body (i.e., the storage board cabin) of the test equipment, which includes a plurality of storage board structures of the test equipment as described above;

[0118] In the present invention, specifically, for any one storage board structure, the concave portion 21 of one storage board unit 1 thereof is connected to the convex portion 20 of one storage board unit 1 of the adjacent storage board structure.

[0119] It should be noted that the specific connection manner between the two storage board units 1 in the two storage board structures is the same as the connection manner between the adjacent two storage board units 1 in the storage board structure of one test equipment as described above, and will not be elaborated here.

[0120] In the present invention, specifically, the storage body (i.e., the storage board cabin) of the test equipment is located in a factory building.

[0121] In the present invention, specifically, the storage body (i.e., the test cabin) of the test equipment is a hollow and sealed storage body.

[0122] It should be noted that for the present invention, refer to Figure 9 、 Figure 10 As shown, when it is necessary to form a wall (for example, a vertically distributed wall, which is usually the side wall of the test cabin) of the storage body (i.e., the test cabin) of the test equipment by a plurality of storage board units 1 together, for any one storage board unit 1, its structural design may include the following three cases:

[0123] First, when there are other storage panel units 1 to be spliced on the front, back, left, and right sides of the storage panel unit 1 (for example, the storage panel unit located at the center position), at this time, the six surfaces included in the storage panel unit 1 are the inner panel 12, the outer panel 13, two outer convex parts 20 (distributed on two surfaces), and two inner concave parts 21 (distributed on two surfaces);

[0124] Second, if three surfaces of the storage panel unit 1 need to be docked with other storage panel units 1, then at this time, one of the outer convex parts or inner concave parts of the storage panel unit 1 is adjusted to a plane, and the plane material is the same as that of the outer panel 13;

[0125] Third, if two surfaces of the storage body of the storage panel unit 1 need to be docked with other storage panel units 1, then at this time, two of the outer convex parts or inner concave parts of the storage panel unit 1 are adjusted to a plane, and the plane material is the same as that of the outer panel 13.

[0126] In summary, for the present invention, the connection methods between the storage panels on the storage body (i.e., the storage panel cabin) of the test equipment and the factory building top beam 4 and the factory building side beam 5 all have flexible adjustable spacing. Since there will be relatively large assembly tolerances in the assembly of the ultra-large storage body and the construction of the factory building, there will be a phenomenon of uneven spacing between the top plate and side plate of the storage body and the factory building top beam and side beam. This connection method can realize the adjustment of the installation spacing, effectively offset the tolerances of the ultra-large storage body and the factory building construction, and utilize the existing steel beams in the factory building (i.e., the factory building top beam 4 and the factory building side beam 5) to strengthen the overall structure of the storage body, greatly reducing the manufacturing cost.

[0127] It should be noted that for the present invention, it is applied to the storage body of the test equipment (i.e., the storage panel cabin of the test equipment that needs to simulate high and low temperature and humid environment). In view of the fact that during the construction of the large storage body, due to the too large internal volume of the large storage body and the large temperature difference between the inside and outside of the storage body, the ultra-large storage body is extremely prone to problems such as local deformation of the storage panel, peeling of the storage panel, and insufficient overall construction strength of the storage body during construction and use;

[0128] Regarding the problem of local deformation of the storage panel, a splicing structure of multiple storage panel units can be used. Each storage panel unit is provided with a telescopic weld formed by folding and welding. When the inner panel of the storage panel unit undergoes thermal expansion and contraction deformation and causes local stress, the telescopic weld can effectively eliminate the stress, thereby avoiding the occurrence of local deformation;

[0129] Regarding the problem of peeling of the storage body, a layer of high-temperature resistant glue is applied to the inner panel of the storage panel unit of the storage body before polyurethane foaming, which can increase the adhesion of the inner panel. In addition, the present invention also adopts the method of resistance welding and planting nails on the inner panel of the storage panel unit to install a limit baffle. When the polyurethane foaming is completed, the limit baffle can provide a certain pulling force for the inner panel, thereby effectively preventing the phenomenon of peeling of the storage panel.

[0130] Regarding the issue of the overall strength of the library body construction, the present invention can utilize the original steel structure beams in the factory building (i.e., the roof beam 4 and the side beam 5 of the factory building) to strengthen the strength after the installation of the library body. And based on the above design, it can offset the manufacturing tolerances of the library panels and the factory building construction, flexibly meet the tolerance requirements of the installation position, and compared with the traditional installation method, it can greatly save the manufacturing cost.

[0131] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
