[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] See also Figures 1 to 5 As shown, according to an embodiment of this application, a support structure is provided, including a flexible support component 100 and a rigid support component 200 arranged opposite to each other along the axial direction of the device to be supported. The flexible support component 100 is used to absorb the axial deformation of the device to be supported during operation, and the rigid support component 200 is used to limit and fix the axial direction of the device to be supported.

[0022] The support structure provided in the embodiments of this application, by arranging flexible support components 100 and rigid support components 200 opposite to each other along the axial direction of the equipment to be supported and clearly defining their functional division, not only avoids the over-design defects of small units through functional modular design, making the overall structure more streamlined, but also saves on-site operating space and reduces the manufacturing cost for compressor manufacturers, achieving multiple objectives of adapting to deformation, reliable support, space optimization, and cost control. Specifically, the flexible support component 100 can be specifically adapted to the overall axial large deformation characteristics of ultra-low temperature small centrifugal compressor units under the action of ultra-low temperature operating conditions, effectively absorbing the axial deformation generated during equipment operation, avoiding deformation stress from damaging the equipment body or support structure, and ensuring the stability of equipment operation; the rigid support component 200 can reliably realize the axial limitation and fixation of the equipment, ensuring the structural reliability of the support.

[0023] The flexible support component 100 and the rigid support component 200 are both located at the bottom of the equipment to be supported and are arranged opposite to each other along the central axis of the equipment to be supported. They are fixedly connected to the outer shell of the equipment to be supported, so as to achieve axial deformation absorption and limiting fixation functions in a coordinated manner through bottom support.

[0024] Specifically, the flexible support component 100 and the rigid support component 200 are arranged correspondingly along the axial direction of the equipment to be supported. Their installation positions can be selected as the front and rear ends of the axial direction of the equipment to be supported, or support positions close to both ends of the axial direction of the equipment to be supported.

[0025] In some specific examples, the flexible support component 100 includes one or more low-temperature resistant elastomer support blocks. The support blocks are arranged along the axial direction of the equipment to be supported. The material can be selected from ultra-low temperature resistant silicone rubber, fluororubber, or polyurethane elastomer, with a hardness of Shore A50 to 80. The upper end face of the support block is fixedly connected to the bottom shell of the equipment to be supported, and the lower end face is fixedly connected to the mounting foundation. The connection method can be bolted, bonded, or pressed. The axial height of the support block is designed as needed according to the maximum axial deformation requirements of the equipment to be supported, and a deformation allowance of 10mm to 50mm is reserved. Its radial cross-section can be rectangular, circular, or irregular to adapt to the shell contour of the equipment to be supported.

[0026] Specifically, in practical applications, when the equipment to be supported undergoes axial deformation, the low-temperature resistant elastomer support block can directly absorb the axial deformation of the equipment through its own axial compression or tension deformation. In addition, the low-temperature resistant material used in the support block ensures that it will not crack or lose its elasticity under ultra-low temperature conditions, thereby ensuring the long-term stability of the support structure.

[0027] In some specific examples, the rigid support assembly 200 includes one or more low-temperature resistant rigid supports. These supports are made of low-temperature resistant metal materials such as 304 stainless steel or Q235 carbon steel, and are formed through machining or welding. The supports are generally block-shaped or plate-shaped, with connection holes on their upper surfaces matching the bottom shell of the equipment to be supported, and their lower surfaces fitting snugly against the mounting foundation. The supports are fixedly connected to the bottom shell of the equipment to be supported and the mounting foundation respectively using high-strength bolts. Their axial length is designed according to axial limiting requirements to ensure that they are arranged relative to the flexible support assembly 100 along the axial direction of the equipment to be supported, while their radial cross-section adapts to the contour of the equipment's shell.

[0028] Specifically, in practical applications, when the equipment to be supported undergoes axial deformation, the low-temperature rigid support, thanks to the high axial stiffness provided by its metallic material, does not produce any axial deformation. The rigid fixing effect of the high-strength bolts forms a reliable axial constraint, directly limiting the axial movement of the supported equipment and ensuring that it remains in the preset installation position, avoiding malfunctions such as pipe pulling and component collisions caused by axial displacement. Furthermore, the low-temperature resistant metal materials used in the support, such as 304 stainless steel and Q235 carbon steel, maintain their structural strength without weakening or cracking in ultra-low temperature environments, ensuring long-term stability of the rigid constraint performance. Together with the flexible support component 100, they form a synergistic effect, absorbing axial deformation at one end and rigidly limiting and fixing at the other. This precisely adapts to the usage requirements of the unit under ultra-low temperature conditions and avoids the over-design defects of traditional supports through a simplified structural design.

[0029] Furthermore, the flexible support component 100 and the rigid support component 200 can also be configured as follows: In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the flexible support assembly 100 includes at least two plate-shaped members 1, and the at least two plate-shaped members 1 are perpendicular to the axial direction of the device to be supported, and have the ability to undergo elastic deformation along the axial direction of the device to be supported, so as to absorb the axial deformation generated by the device to be supported during operation through their own elastic deformation.

[0030] In this embodiment, a flexible support assembly 100 is constructed by using at least two plate-shaped members 1 perpendicular to the axial direction of the equipment to be supported. By utilizing the ability of the plate-shaped members 1 to easily undergo bending deformation when subjected to bending or shear forces, the axial deformation generated during the operation of the equipment to be supported can be absorbed. Furthermore, the arrangement perpendicular to the axial direction can effectively constrain excess radial deformation, ensuring the targeted and stable absorption of deformation. At the same time, the flexible support assembly 100 composed of plate-shaped members 1 has a simple structure, occupies little space, and has low manufacturing cost, avoiding the over-design defects of traditional support structures.

[0031] Among them, plate-shaped component 1 is a flat structure with a thickness much smaller than its length and width.

[0032] Specifically, the plate-shaped member 1 of the flexible support component 100 is made of Q345R low-alloy high-strength steel, and its arrangement direction is perpendicular to the axis of the equipment to be supported, that is, the planar direction of the plate-shaped member 1 is orthogonal to the axis of the equipment to be supported. Based on the material properties of Q345R steel and the geometric characteristics of the plate structure, the planar stiffness of the plate-shaped member 1 is significantly higher than that in the thickness direction: due to the large moment of inertia of the material section in the planar direction, it has excellent resistance to deformation; the moment of inertia of the section in the thickness direction and the bending direction in the plane is small, and elastic deformation can be generated. When the equipment to be supported undergoes radial deformation during operation, such as radial movement in the left-right direction, the plate-shaped component 1, with its high rigidity in the planar direction, can provide reliable radial support constraint force, directly limiting the radial displacement of the equipment and preventing the equipment from deviating from its operating posture due to radial sway. When the equipment to be supported undergoes axial expansion and contraction deformation, such as stretching or compression in the front-back direction, the plate-shaped component 1 can achieve directional absorption of axial deformation by using its thickness and low rigidity in the planar bending direction as the main method and small elastic deformation in the thickness direction as the auxiliary method.

[0033] Wherein, when the number of plate-shaped members 1 constituting the flexible support assembly 100 is at least two, all plate-shaped members 1 are arranged coplanarly, and the plane in which they are located is the same vertical plane perpendicular to the axis of the equipment to be supported; or, all plate-shaped members 1 are distributed at intervals along the axis of the equipment to be supported, and each plate-shaped member 1 is located in a vertical plane perpendicular to the axis of the equipment to be supported, and the vertical planes do not overlap.

[0034] Specifically, in this embodiment, see Figure 1 and Figure 2As shown, the number of plate-shaped members 1 constituting the flexible support assembly 100 is set to two, and the two plate-shaped members 1 are located in the same vertical plane, and the vertical plane is perpendicular to the axial direction of the equipment to be supported. Here, two plate-shaped components 1 are arranged in the same vertical plane perpendicular to the axial direction of the equipment to be supported. On the one hand, the coplanar arrangement in the same vertical plane makes the planar support forces of the two plate-shaped components 1 synergistic and complementary. Utilizing the anti-deformation ability brought by their high cross-sectional moment of inertia in the planar direction, the balance and reliability of radial constraint are further improved, which can more stably restrict the radial movement of the equipment to be supported and avoid deviation of the equipment's operating posture. On the other hand, the arrangement perpendicular to the axial direction, combined with the thickness of the plate-shaped components 1 and the low stiffness characteristics in the planar bending direction, allows the two plate-shaped components 1 to simultaneously absorb the axial expansion and contraction deformation of the equipment to be supported in a directional and efficient manner through in-plane bending deformation, ensuring the targeted and stable deformation absorption. At the same time, the simplified structure of the double plate-shaped components 1 does not increase the space occupied or manufacturing cost, and strengthens the support performance through synergistic effect. It not only meets the radial limiting and axial deformation absorption requirements of the equipment under ultra-low temperature conditions, but also further avoids the over-design defects of traditional support structures, ensuring the long-term stability and reliability of the equipment to be supported.

[0035] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the rigid support assembly 200 includes at least two plate-shaped members 1, and the at least two plate-shaped members 1 are parallel to the axial direction of the device to be supported, and have the ability to resist deformation along the axial direction of the device to be supported.

[0036] In this embodiment, the rigid support assembly 200 is configured as at least two plate-shaped members 1 parallel to the axial direction of the equipment to be supported and possessing axial deformation resistance. The axial deformation resistance capability of the plate-shaped structure with its high cross-sectional moment of inertia along the direction parallel to its own plane can be utilized to form a stable and direct axial constraint on the equipment to be supported, effectively resisting axial movement of the equipment during operation and ensuring that the equipment always maintains its installation position. At the same time, the coordinated arrangement of at least two members can achieve multi-point balanced support, which not only disperses the axial force and improves the reliability and stability of the rigid constraint, but also avoids the local stress concentration problem that may be caused by single-point constraint. In addition, the plate-shaped member 1 has a simple structure and occupies little space. The arrangement parallel to the axial direction does not increase the radial installation space, avoiding the over-design defects of traditional support structures.

[0037] In this embodiment, the plate-shaped member 1 constituting the rigid support assembly 200 has the same geometric structure, material, and connection and fixing method as the plate-shaped member 1 constituting the flexible support assembly 100. Specific technical details regarding these identical features of the plate-shaped member 1 constituting the rigid support assembly 200 will not be repeated here. The difference lies in that the plate-shaped member 1 constituting the flexible support assembly 100 is perpendicular to the axial direction of the equipment to be supported, exhibiting high planar stiffness and low thickness and planar bending stiffness, thus meeting the functional requirements for axial deformation absorption; while the plate-shaped member 1 constituting the rigid support assembly 200 is parallel to the axial direction of the equipment to be supported, maximizing its axial section moment of inertia, thus meeting the rigid constraint requirements for axial deformation resistance.

[0038] Specifically, when the plate-shaped member 1 constituting the rigid support assembly 200 is arranged parallel to the axial direction of the equipment to be supported, its planar direction is completely consistent with the axial direction of the equipment. Combined with its flat geometric feature where its thickness is much smaller than its length and width, the effective load-bearing cross-section of the plate-shaped member 1 under axial force presents an optimized shape of height multiplied by thickness. Under this arrangement, the cross-sectional height is significantly greater than the thickness dimension, and the resulting axial cross-sectional moment of inertia is much higher than in other arrangement directions, giving the plate-shaped member 1 extremely strong axial resistance to bending, tension, or compression. When the equipment to be supported undergoes axial deformation, the plate-shaped member 1 will not undergo any perceptible axial elastic or plastic deformation. Instead, it will directly transmit the axial force to the installation foundation through its own high stiffness characteristics, limiting the axial displacement of the equipment to be supported.

[0039] When the number of plate-shaped members 1 constituting the flexible support component 100 is at least two, all plate-shaped members 1 are parallel to the axial direction of the equipment to be supported and are parallel to each other. Their arrangement can be symmetrically arranged relative to each other along the radial direction of the equipment to be supported or evenly spaced along the radial circumference of the equipment to be supported.

[0040] Specifically, in this embodiment, see Figure 1 and Figure 2 As shown, the rigid support assembly 200 comprises two plate-shaped members 1, which are arranged radially opposite to each other and parallel to each other. At this time, the two plate-shaped members 1 are symmetrically distributed at 180° along the radial direction of the equipment to be supported. The plane of each plate-shaped member 1 coincides with or is parallel to the vertical plane, ensuring a balanced support constraint along the radial direction. Simultaneously, the parallel arrangement ensures that the load-bearing state of the two plate-shaped members 1 is completely symmetrical, eliminating the problem of stress concentration on one side. This ensures that the axial constraint force is uniformly transmitted to the installation foundation, preventing slight axial tilting of the equipment to be supported due to unbalanced constraints, and ensuring that the equipment to be supported always maintains a stable installation posture.

[0041] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 3 to 5As shown, the plate-shaped member 1 constituting the flexible support assembly 100 and the rigid support assembly 200 has a stress relief groove 11 on the welding mating surface with the shell of the device to be supported; the stress relief groove 11 extends in a direction perpendicular to the axial direction of the device to be supported and penetrates the plate-shaped member 1 along the thickness direction of the plate-shaped member 1, and the stress relief groove 11 is used to release the welding stress generated when the plate-shaped member 1 is welded to the shell of the device to be supported.

[0042] In this embodiment, by providing a stress relief groove 11 that extends perpendicular to the axial direction of the equipment to be supported and penetrates the thickness of the plate member 1 at the welding mating surface of the plate member 1 and the housing of the equipment to be supported, the residual welding stress generated by the high-temperature thermal cycle during the welding connection can be efficiently released. This avoids stress concentration that could lead to microcracks in the weld joint or irreversible deformation of the plate member 1. This ensures the structural stability and load-bearing reliability of the welded connection without affecting the axial deformation absorption of the flexible support component 100 or the axial deformation resistance of the rigid support component 200. It effectively avoids the adverse effects of welding stress on the overall performance of the support structure, further extends the service life of the support structure, and ensures the long-term stability of the synergistic support effect of the flexible and rigid supports.

[0043] In this embodiment, see Figure 1 and Figure 2 As shown, the plate-shaped members 1 that constitute the flexible support assembly 100 and the rigid support assembly 200 have a welding mating surface that is attached to and forms a welded connection with the outer shell of the equipment to be supported. This surface is the top surface of the plate-shaped member 1 when it is in the installation working state, that is, the upper surface of the plate-shaped member 1 when it is vertically arranged.

[0044] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 3 to 5 As shown, the stress relief groove 11 has a stress relief hole 12 at the bottom. The stress relief hole 12 penetrates the plate-shaped member 1 along the thickness direction. The stress relief hole 12 is used to assist in bearing the weight of the equipment to be supported, so as to disperse the stress concentration at the bottom of the stress relief groove 11, thereby preventing the stress relief groove 11 from splitting due to excessive local stress.

[0045] In this embodiment, by providing stress relief holes 12 that penetrate along the thickness direction of the plate-shaped member 1 at the bottom of the stress relief groove 11, the local stress concentration caused by the load on the bottom of the stress relief groove 11 due to bearing the weight of the equipment to be supported can be dispersed through the hole structure, effectively preventing the bottom of the groove from splitting due to stress overload. At the same time, the original function of the stress relief groove 11 in releasing welding residual stress can be retained. Furthermore, the through-hole stress relief hole 12 does not weaken the ability of the plate-shaped member 1 to adapt to the axial deformation absorption of the flexible support component 100 or the axial deformation resistance of the rigid support component 200. It can also improve the structural reliability of the welded connection between the plate-shaped member 1 and the shell of the equipment to be supported and the overall service life of the support structure, ensuring the long-term stability of the synergistic support effect of the flexible support and the rigid support.

[0046] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 3 to 5 As shown, the stress relief hole 12 is a circular hole.

[0047] In this embodiment, by setting the stress relief hole 12 as a circular hole, the secondary stress concentration around the hole can be avoided due to its non-angular structure, which further optimizes the stress distribution at the bottom of the stress relief groove 11 and can more efficiently disperse the local concentrated stress caused by the gravity of the equipment to be supported, thereby strengthening the anti-splitting protection of the groove bottom; at the same time, the processing technology of the circular hole is mature and simple, which can reduce the manufacturing cost.

[0048] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 3 to 5 As shown, the plate-shaped member 1 has a base 2 at its bottom on the side away from the equipment to be supported. The base 2 is fixedly connected to the mounting foundation for installing the equipment to be supported, so as to achieve a stable assembly of the support structure and the mounting foundation.

[0049] In this embodiment, by setting a base 2 fixedly connected to the installation foundation on the bottom side of the plate member 1 away from the equipment to be supported, the contact area between the plate member 1 and the installation foundation can be increased. This can not only uniformly transfer the weight of the equipment to be supported and the axial and radial forces generated during operation to the installation foundation, avoiding local stress concentration that could lead to loosening of the connection between the plate member 1 and the installation foundation or damage to the installation foundation, but also achieve a stable assembly of the support structure and the installation foundation, thereby improving the overall overturning resistance and installation reliability of the support structure.

[0050] The base 2 can be a rectangular or directional flat steel plate, and the material is the same as that of the plate component 1, such as Q345R steel.

[0051] Specifically, the upper surface of the base 2 is welded and fixed to the bottom of the plate-shaped component 1; multiple connection holes are opened on the base 2, and it is fixed to the mounting foundation by high-strength bolts. Here, the mounting foundation can be a concrete foundation or a steel structure foundation, etc.

[0052] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 3 to 5 As shown, the thickness of the plate-shaped member 1 is 30mm to 50mm.

[0053] In this embodiment, for the plate-shaped member 1 of the flexible support assembly 100, the thickness of the plate-shaped member 1 is set to 30mm to 50mm. This ensures high stiffness in the planar direction to achieve radial constraint while retaining the low stiffness characteristics in the thickness and planar bending direction, ensuring efficient absorption of the axial deformation of the supported equipment. For the plate-shaped member 1 of the rigid support assembly 200, the thickness of the plate-shaped member 1 is set to 30mm to 50mm. This thickness can form a sufficient axial section moment of inertia, giving it extremely strong axial resistance to deformation and achieving reliable axial limiting. At the same time, the thickness of 30mm to 50mm can balance the structural strength and lightweight requirements, avoiding the risk of brittleness and insufficient load-bearing capacity under ultra-low temperature conditions due to excessive thickness, or structural redundancy, increased space occupation, and increased manufacturing costs due to excessive thickness, further ensuring the long-term stable operation of the support structure.

[0054] In some specific examples, the thickness of the plate-shaped member 1 is 30mm, 40mm, or 50mm. It should be noted that the thickness of the plate-shaped member 1 can also be other values ​​besides those mentioned above, as long as the thickness of the plate-shaped member 1 is within the range of 30mm to 50mm.

[0055] Specifically, in this embodiment, the plate-shaped member 1 constituting the flexible support component 100 and the rigid support component 200 preferably has a thickness of 50 mm, corresponding to a length of 1200 mm and a width of 500 mm.

[0056] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

The above are merely preferred embodiments of this application.
