Description

Technical Field

[0001] This invention relates to a mobile support device and a nuclear reactor system. Background Technology

[0002] In the existing technology, the moving support device used to support the tank in the nuclear reactor system has problems such as insufficient load-bearing capacity, single direction of movement, poor reliability, and reliance on active control drive. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a mobile support device and a nuclear reactor system.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A movable support device is used to support a tank body that undergoes radial thermal expansion displacement under temperature and axial displacement along a thrust pipe connected to the tank body, wherein the central axis of the thrust pipe is perpendicular to the central axis of the tank body. The movable support device comprises:

[0006] Fixed base;

[0007] The adapter frame is movable relative to the fixed base along the axial direction of the thrust pipe to compensate for the displacement of the tank body along the axial direction of the thrust pipe.

[0008] A friction-reducing base is provided, on which the tank body is fixed, and the friction-reducing base is slidably connected to the adapter frame. The friction-reducing base can move radially along the tank body to compensate for the thermal expansion displacement of the tank body along the radial direction.

[0009] In this technical solution, by setting a specific structure for the movable support device, specifically by setting a transition frame that can move relative to the fixed base surface of the fixed base along the axial direction of the thrust pipe, the displacement of the tank along the axial direction of the thrust pipe can be compensated. By setting a friction-reducing base that can move along the radial direction of the tank, the thermal expansion displacement of the tank along the radial direction of the tank can be compensated. The combination of the two can not only realize the passive multi-directional coupled displacement movement of the supported equipment (tank and other components) at the same time, but also has excellent performance such as simple structure, strong load-bearing capacity and stable movement. It has broad application prospects in the field of reliable support for large heavy-duty transportation equipment or special operation equipment (such as nuclear power, aerospace).

[0010] Preferably, the friction-reducing base includes multiple friction-reducing parts, which are spaced apart circumferentially along the tank body, and all of the multiple friction-reducing parts can move radially along the tank body.

[0011] In this technical solution, by setting a friction-reducing base including multiple friction-reducing parts spaced circumferentially along the tank body, the relative sliding between the friction-reducing parts and the adapter frame can be used to achieve displacement compensation of the tank body along the radial direction of the tank body.

[0012] Preferably, the friction-reducing part includes a friction-reducing lubrication base surface that abuts against the adapter frame, and a friction-reducing mounting base surface for mounting the tank; the friction-reducing lubrication base surface has a plurality of friction-reducing receiving holes for accommodating friction-reducing material, and a portion of the friction-reducing material protrudes from the friction-reducing lubrication base surface; and / or,

[0013] The plurality of friction-reducing parts are identical in shape and size, and / or, the plurality of friction-reducing parts are equidistantly spaced along the circumference of the tank; and / or,

[0014] The tank body has a cylindrical structure, and the friction-reducing part has an arc-shaped structure.

[0015] In this technical solution, by making a portion of the friction-reducing material protrude from the friction-reducing lubrication base surface, the friction-reducing material is partially located between the friction-reducing lubrication base surface and the surface in contact with the adapter frame. This reduces the relative sliding friction when the moving support device compensates for the radial thermal expansion displacement of the tank body, thereby reducing the thrust load requirement on the thrust pipeline during the operation of the passive multi-directional coupling moving support device, ensuring that the system stress level meets the design limits. By setting multiple friction-reducing parts of the same shape and size, and / or by equidistantly arranging multiple friction-reducing parts along the circumference of the tank body, a uniform distribution is achieved in the design and installation, effectively optimizing the contact pressure distribution, improving motion stability, extending service life, reducing installation difficulty, and lowering maintenance costs.

[0016] Preferably, the adapter frame includes:

[0017] The receiving body, wherein the friction-reducing base abuts against the receiving surface of the receiving body;

[0018] The first ear seat and the second ear seat are respectively disposed on both sides of the receiving body and symmetrically disposed on both sides of the plane containing the central axis of the thrust pipe and the central axis of the tank. The first ear seat and the second ear seat are respectively provided with sliding components between them and the fixed base surface of the fixed base.

[0019] In this technical solution, by setting the specific positions of the first and second lugs of the adapter frame, a circumferentially symmetrical distribution design is achieved, which effectively optimizes the load distribution of the supported equipment and improves the equipment's motion stability. A sliding component is used to realize the relative movement between the adapter frame and the fixed base, thereby achieving axial displacement compensation of the tank body along the thrust pipeline.

[0020] Preferably, the receiving body includes a detachably connected first part and a second part, the first ear seat being disposed on the outer edge of the first part, and the second ear seat being disposed on the outer edge of the second part; and / or,

[0021] The fixing surface of the fixing base is a flat surface.

[0022] In this technical solution, the receiving body is configured with a detachable first part and a second part to facilitate the installation and maintenance of the adapter frame. The fixed base surface is used to bear the total load of other components, including the thrust pipe, tank assembly, and moving support device. By setting the fixed base surface to be a flat surface, it has high flatness, rigidity, and strength to ensure the operational stability and reliability of the sliding assembly.

[0023] Preferably, the adapter further includes a first reinforcing rib, which is at least partially disposed on the side of the first ear seat away from the sliding assembly and on the side of the first portion away from the sliding assembly; and / or,

[0024] The adapter further includes a second reinforcing rib, which is at least partially disposed on the side of the second ear seat away from the sliding assembly, and on the side of the second ear seat away from the sliding assembly; and / or,

[0025] The first part and the second part are connected circumferentially, and a third ear and a fourth ear are provided at the connection between the first part and the second part. The third ear and the fourth ear are symmetrically arranged and connected to the outer edge of the receiving body. A third reinforcing rib is provided on the side of the third ear facing the fixed base. The two adjacent sides of the third reinforcing rib are respectively connected to the third ear and the receiving body. And / or, a fourth reinforcing rib is provided on the side of the fourth ear facing the fixed base. The two adjacent sides of the fourth reinforcing rib are respectively connected to the fourth ear and the receiving body.

[0026] In this technical solution, a first reinforcing rib is provided to enhance the structural strength of the first ear and the supporting body. A second reinforcing rib is provided to enhance the structural strength of the second ear and the supporting body. A third reinforcing rib is provided to enhance the structural strength of the third ear and the supporting body. A fourth reinforcing rib is provided to enhance the structural strength of the fourth ear and the supporting body.

[0027] Preferably, the two sliding components are respectively disposed on both sides of the receiving body, and symmetrically disposed on both sides of the plane containing the central axis of the thrust pipe and the central axis of the tank; and / or,

[0028] The sliding component includes:

[0029] support;

[0030] The roller is pivotally connected to the bracket;

[0031] The track base is fixed to the fixed base surface of the fixed base and is provided with a track, on which the rollers roll.

[0032] In this technical solution, two sliding components are respectively positioned on both sides of the receiving body, symmetrically arranged on both sides of the plane containing the central axis of the thrust pipe and the central axis of the tank. This achieves a circumferentially symmetrical distribution design of the sliding components, effectively optimizing the load distribution of the supported equipment and improving its motion stability. By mounting the sliding components on a fixed base, the sliding components drive the tank to passively roll on the fixed surface of the fixed base, compensating for the passive thermal expansion displacement of the tank along the axial direction of the thrust pipe.

[0033] Preferably, the bracket includes a bracket mounting plate and baffles disposed on opposite sides of the bracket mounting plate;

[0034] The sliding assembly also includes a central shaft, with its two ends respectively passing through the two baffles, and the rollers are pivotally connected to the bracket via the central shaft.

[0035] In this technical solution, by setting the two ends of the central shaft to pass through two baffles respectively, the roller is pivotally connected to the bracket through the central shaft, which can provide a stable pivot structure for the roller to roll on the track.

[0036] Preferably, a boss is provided on the inner wall of the roller; along the axial direction of the central shaft, two bearings are spaced apart outside the central shaft, the two bearings are spaced apart along the axial direction of the central shaft and are both located inside the inner hole of the roller, and the boss is located between the two bearings.

[0037] The outer side of the central shaft is provided with a retaining ring groove, and the retaining ring is engaged in the retaining ring groove. The side of the bearing away from the boss abuts against the retaining ring.

[0038] In this technical solution, through the above-mentioned settings, the inner ring of the bearing is axially positioned by the limiting of the snap ring in the snap ring groove, and the outer ring of the bearing is axially positioned by the roller boss.

[0039] A nuclear reactor system, characterized in that the nuclear reactor system comprises:

[0040] The tank assembly includes a tank and mounting lugs disposed around the periphery of the tank, wherein a pipe interface is provided on one side of the tank;

[0041] The thrust pipe is installed on the tank body through the pipe interface; and

[0042] As described above, in the movable support device, the tank body is mounted on the movable support device via the mounting lugs.

[0043] The positive and progressive effects of this invention are as follows:

[0044] By setting a specific structure for the movable support device, specifically by setting a transition frame that can move along the axial direction of the thrust pipe relative to the fixed base surface of the fixed base, the displacement of the tank along the axial direction of the thrust pipe can be compensated. By setting a friction-reducing base that can move along the radial direction of the tank, the thermal expansion displacement of the tank along the radial direction of the tank can be compensated. The combination of the two can not only realize the passive multi-directional coupled displacement movement of the supported equipment (tank and other components) at the same time, but also has excellent performance such as simple structure, strong load-bearing capacity and stable movement. It has broad application prospects in the field of reliable support for large heavy-duty transportation equipment or special operation equipment (such as nuclear power, aerospace).

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0110] This embodiment provides a mobile support device and a nuclear reactor system.

[0111] like Figures 1 to 3 As shown, the nuclear reactor system 100 of this embodiment includes: a tank assembly 1, a thrust pipe 2, and a moving support device 3.

[0112] The tank assembly 1 includes a tank body 11 and mounting lugs 12 disposed around the periphery of the tank body 11. A pipe interface 13 is provided on one side of the tank body 11. The thrust pipe 2 is installed on the tank body 11 through the pipe interface 13. The central axis p of the thrust pipe 2 is perpendicular to the central axis q of the tank body 11, so that the axial direction P of the thrust pipe 2 is one of the radial directions of the tank body 11.

[0113] The tank body 11 is mounted on the movable support device 3 via mounting lugs 12.

[0114] Specifically, such as Figures 4 to 10 As shown, the movable support device 3 in this embodiment is used to support the tank 11. Under the action of temperature, the tank 11 undergoes radial thermal expansion displacement, and under the action of thermal expansion of the thrust pipe 2 connected to the tank 11, it undergoes axial displacement P along the thrust pipe 2. The movable support device 3 includes: a fixed base 31, an adapter frame 32, and a friction-reducing base 33.

[0115] The adapter 32 can move relative to the fixed base 31 along the axial direction P of the thrust pipe 2 to compensate for the displacement of the tank 11 along the axial direction P of the thrust pipe 2.

[0116] The tank body 11 is fixed on the friction-reducing base 33, and the friction-reducing base 33 is slidably connected to the adapter 32. The friction-reducing base 33 can move radially along the tank body 11 to compensate for the radial thermal expansion displacement of the tank body 11.

[0117] In this way, by setting the specific structure of the mobile support device 3, specifically by setting the adapter 32 to move relative to the fixed base surface 311 of the fixed base 31 along the axial direction P of the thrust pipe 2, the displacement of the tank 11 along the axial direction P of the thrust pipe 2 can be compensated. By setting the anti-friction base 33 to move along the radial direction of the tank 11, the thermal expansion displacement of the tank 11 along the radial direction of the tank 11 can be compensated. The combination of the two can not only realize the passive multi-directional coupled displacement movement of the supported equipment (such as the tank 11 and other components) at the same time, but also has excellent performance such as simple structure, strong load-bearing capacity and stable movement. It has broad application prospects in the field of reliable mobile support for large heavy-duty transportation equipment or special operation equipment (such as nuclear power, aerospace). It should be noted that since the tank body 11 is fixed to the friction-reducing base 33, the tank body 11 and the friction-reducing base 33 are the same rigid body that is fixedly installed. The tank body 11 and the friction-reducing base 33 move together along the radial direction of the tank body 11, thereby compensating for the radial thermal expansion displacement of the tank body 11. In addition, the friction-reducing base 33 is slidably connected to the adapter frame 32, that is, the friction-reducing base 33 can generate relative displacement with respect to the adapter frame 32.

[0118] Preferably, the friction-reducing base 33 includes a plurality of friction-reducing parts 331, which are spaced apart circumferentially along the tank body 11, and all of the friction-reducing parts 331 can move radially along the tank body 11. Thus, by including a plurality of friction-reducing parts 331 spaced apart circumferentially along the tank body 11 in the friction-reducing base 33, displacement compensation of the tank body 11 along the radial direction can be achieved by utilizing the relative sliding between the friction-reducing parts 331 and the adapter frame 32. In this embodiment, the number of friction-reducing parts 331 is three, but it is not limited to this; in other embodiments, the number of friction-reducing parts 331 can also be four, five, or other numbers.

[0119] The friction-reducing part 331 includes a friction-reducing lubrication base surface 3311 that abuts against the adapter frame 32, and a friction-reducing mounting base surface 3312 for mounting the tank body 11. The friction-reducing lubrication base surface 3311 is provided with a plurality of friction-reducing receiving holes 3313 for accommodating friction-reducing materials (i.e., the friction-reducing receiving holes 3313 are filled with friction-reducing materials). Some of the friction-reducing materials protrude from the friction-reducing lubrication base surface 3311. Thus, during the sliding process of the friction-reducing part 331 relative to the adapter frame 32, the friction-reducing materials will be partially located between the friction-reducing lubrication base surface 3311 and the surface of the adapter frame 32 that contacts it. In this way, by making part of the friction-reducing material protrude from the friction-reducing lubrication base surface 3311, the friction-reducing material will be partially located between the friction-reducing lubrication base surface 3311 and the surface of the adapter 32 that contacts it. This reduces the relative sliding friction when the moving support device 3 compensates for the radial thermal expansion displacement of the tank 11, thereby reducing the thrust load requirement on the thrust pipe 2 when the passive multi-directional coupling moving support device 3 is working, so that the system stress level meets the design limit requirements. Specifically, the friction-reducing mounting hole 3314 is a stepped through hole, and the friction-reducing receiving hole 3313 is set as a single-sided blind hole.

[0120] It should be noted that some of the friction-reducing material protrudes from the friction-reducing lubrication base surface 3311, thus forming microscopic bosses. When the tank 11 equipment undergoes thermal expansion, these microscopic friction-reducing bosses reduce the relative sliding friction between the bearing surface 3211 and the friction-reducing plate lubrication base surface, reducing the wear of the contact pair, preventing "stick-slip" phenomena between the contact surfaces, ensuring stable frictional resistance, improving the motion accuracy and stability of the tank 11 equipment and moving support, reducing vibration and noise during operation, reducing the load requirements on the thrust pipe 2, and preventing excessively high system stress levels. The friction-reducing material is a commercially available product; any material capable of reducing the relative sliding friction between the bearing surface 3211 and the friction-reducing lubrication base surface 3311 is acceptable.

[0121] The mounting lug 12 of the tank assembly 1 includes a tank mounting base 123; the tank mounting base 123 is fixedly installed with the friction-reducing mounting base 3312 of the friction-reducing part 331 in the movable support device 3; the tank mounting base 123 is provided with a tank mounting hole 122, and the friction-reducing mounting base 3312 is provided with a friction-reducing mounting hole 3314; the connection between the tank mounting base 123 and the friction-reducing mounting base 3312 is achieved by locking the tank mounting hole 122 and the friction-reducing mounting hole 3314 with bolts and nuts.

[0122] Multiple friction-reducing parts 331 are identical in shape and size, and are equidistantly spaced along the circumference of the tank body 11 to achieve uniform distribution in design and installation. This effectively optimizes the contact pressure distribution, improves motion stability, extends service life, reduces installation difficulty, and lowers maintenance costs.

[0123] In this embodiment, the tank body 11 has a cylindrical structure, and the friction-reducing part 331 has an arc-shaped structure, which corresponds to a part of the cylindrical structure of the tank body 11, thereby better conforming to the radial thermal expansion displacement of the tank body 11.

[0124] Specifically, the adapter 32 includes: a receiving body 321, a first ear seat 322, and a second ear seat 323. The friction-reducing base 33 abuts against the receiving surface 3211 of the receiving body 321.

[0125] The first ear seat 322 and the second ear seat 323 are respectively disposed on both sides of the receiving body 321, and are symmetrically disposed on both sides of the plane containing the central axis p of the thrust pipe 2 and the central axis q of the tank 11. A sliding component 34 is provided between the first ear seat 322 and the second ear seat 323 and the fixed base surface 311 of the fixed base 31. That is, in this embodiment, by providing the sliding component 34, the adapter 32 can move relative to the fixed base surface 311 of the fixed base 31 along the axial direction P of the thrust pipe 2. However, this is not the only possibility. In other embodiments, the adapter 32 can also be moved relative to the fixed base surface 311 of the fixed base 31 by directly sliding it onto the fixed base surface 311 of the fixed base 31.

[0126] In this way, by setting the first ear seat 322 and the second ear seat 323 on both sides of the receiving body 321, and symmetrically arranged on both sides of the plane containing the central axis p of the thrust pipe 2 and the central axis q of the tank 11, the adapter frame 32 adopts a circumferentially symmetrical distribution design, which can effectively optimize the load distribution of the supported equipment and improve the motion stability of the equipment. By setting the sliding component 34, the relative movement between the adapter frame 32 and the fixed base 31 is realized, thereby achieving displacement compensation of the tank 11 along the axial direction P of the thrust pipe 2.

[0127] As described above, the tank body 11 has a cylindrical structure, the friction-reducing part 331 has an arc-shaped structure, and thus, the corresponding receiving body 321 has an annular structure.

[0128] Furthermore, the receiving body 321 includes a detachably connected first part 3212 and a second part 3213. A first ear seat 322 is disposed on the outer edge of the first part 3212, and a second ear seat 323 is disposed on the outer edge of the second part 3213. Thus, by providing the receiving body 321 with a detachably connected first part 3212 and a second part 3213, the installation and maintenance of the adapter frame 32 are facilitated. Preferably, the first part 3212 and the second part 3213 are symmetrically arranged.

[0129] The fixed base 311 of the fixed base 31 is a flat surface. The fixed base 311 of the fixed base 31 is used to bear the total load of other components including the thrust pipe 2, the tank assembly 1 and the moving support device 3. By setting the fixed base 311 to be a flat surface, it has high flatness, rigidity and strength to ensure the operational stability and reliability of the sliding assembly 34.

[0130] Preferably, the adapter frame 32 further includes a first reinforcing rib 3261, which is at least partially disposed on the side of the first ear seat 322 away from the sliding component 34 and on the side of the first portion 3212 away from the sliding component 34. In this way, the structural strength of the first ear seat 322 and the supporting body 321 is enhanced by providing the first reinforcing rib 3261.

[0131] The adapter frame 32 also includes a second reinforcing rib 3262, which is at least partially disposed on the side of the second ear seat 323 away from the sliding assembly 34 and on the side of the second portion 3213 away from the sliding assembly 34. In this way, the second reinforcing rib 3262 is provided to enhance the structural strength of the second ear seat 323 and the supporting body 321.

[0132] The first part 3212 and the second part 3213 are connected circumferentially, and a third ear seat 324 and a fourth ear seat 325 are provided at the connection between the first part 3212 and the second part 3213. The third ear seat 324 and the fourth ear seat 325 are symmetrically arranged and connected to the outer edge of the receiving body 321.

[0133] A third reinforcing rib 3263 is provided on the side of the third ear 324 facing the fixed base 31. The two adjacent sides of the third reinforcing rib 3263 are connected to the third ear 324 and the supporting body 321, respectively. In this way, the structural strength of the third ear 324 and the supporting body 321 is enhanced by providing the third reinforcing rib 3263.

[0134] A fourth reinforcing rib 3264 is provided on the side of the fourth ear seat 325 facing the fixed base 31. The two adjacent sides of the fourth reinforcing rib 3264 are connected to the fourth ear seat 325 and the supporting body 321, respectively. In this way, the structural strength of the fourth ear seat 325 and the supporting body 321 is enhanced by providing the fourth reinforcing rib 3264.

[0135] In the supporting body 321, a fifth reinforcing rib 326 is provided on the side away from the bearing surface 3211 to enhance the structural strength of the supporting body 321 itself.

[0136] Preferably, the two sliding components 34 are respectively disposed on both sides of the receiving body 321, and symmetrically disposed on both sides of the plane containing the central axis p of the thrust pipe 2 and the central axis q of the tank 11, so as to realize that the sliding components 34 adopt a symmetrical parallel distribution design along the motion compensation direction, which can effectively optimize the load distribution of the supported equipment and improve the motion stability of the equipment.

[0137] The sliding assembly 34 includes a bracket 341, a roller 342, and a track base 343. The roller 342 is pivotally connected to the bracket 341. The track base 343 is fixed to the fixed base surface 311 of the fixed base 31, and the track base 343 is provided with a track 3431, on which the roller 342 rolls. In this way, by installing the sliding assembly 34 on the fixed base 31, the sliding assembly 34 causes the tank 11 to passively roll on the fixed base surface 311 of the fixed base 31, which is used to compensate for the passive thermal expansion displacement of the tank 11 along the axial direction P of the thrust pipe 2.

[0138] Preferably, the bracket 341 includes a bracket 3411 mounting plate 3411 and baffles 3412 disposed on opposite sides of the bracket 3411 mounting plate 3411. The sliding assembly 34 also includes a central shaft 344, with its two ends respectively passing through the two baffles 3412, and the roller 342 is pivotally connected to the bracket 341 via the central shaft 344.

[0139] In this way, by setting the two ends of the central shaft 344 to pass through the two baffles 3412 respectively, the roller 342 is pivotally connected to the bracket 341 via the central shaft 344, providing a stable pivoting structure for the roller 342 to roll on the track 3431. The bracket 341 mounting plate 3411 has bracket mounting holes 3413, and the sliding component 34 is connected to the first ear mounting hole 3221 and the second ear mounting hole 3231 of the adapter frame 32 through the bracket mounting holes 3413 respectively. The central shaft 344 and the bracket 341 are axially locked by tightening the lock nut.

[0140] Preferably, a boss 3421 is provided on the inner wall of the roller 342; two bearings 347 are spaced apart on the outer side of the central shaft 344 along the axial direction O of the central shaft 344, and both bearings 347 are located within the inner hole of the roller 342, with the boss 3421 positioned between the two bearings 347; a retaining ring 346 groove is provided on the outer side of the central shaft 344, and the retaining ring 346 is engaged in the retaining ring 346 groove, with the side of the bearing 347 away from the boss 3421 abutting against the retaining ring 346. Thus, through the above arrangement, the inner ring of the bearing 347 is axially positioned by the retaining ring 346 within the retaining ring 346 groove, and the outer ring of the bearing 347 is axially positioned by the boss 3421 of the roller 342.

[0141] Furthermore, the baffle 3412 of the bracket 341 is located outside the retaining ring 346, which achieves axial positioning of the inner ring of the bearing 347 while preventing the roller 342 and the outer ring of the bearing 347 from contacting or interfering with the bracket 341. The roller 342 is mounted on the top of the track 3431, and the track base 343 is connected to the fixing base surface 311 of the fixing base 31 through the track base mounting hole 3432. Specifically, the roller 342 is made of steel.

[0142] Furthermore, the roller 342 has a double U-shaped cross-section. The double U-shaped roller 342 is mounted on the track 3431 with a cylindrical cross-section. This mutually cooperating cross-section design helps to reduce the dependence of the sliding component 34 on the lateral guide wheel during the movement and avoids the "jamming" phenomenon. Thus, the simple structure of the sliding component 34 can effectively improve the stability, reliability, and maintainability of the movement.

[0143] The working principle of this embodiment is as follows:

[0144] (1) The specific implementation principle of radial thermal expansion displacement compensation is as follows:

[0145] In this embodiment, when the tank 11 heats up and causes its own thermal expansion, the relative slippage between the friction-reducing lubrication base surface 3311 and the bearing surface 3211 of the adapter 32 can realize the radial thermal expansion displacement compensation of the passive multi-directional coupling mobile support device 3.

[0146] (2) The specific implementation principle of axial thermal expansion displacement compensation is as follows:

[0147] In this embodiment, when the tank 11 and the thrust pipe 2 heat up and cause their own thermal expansion, the roller 342 of the sliding component 34 rolls relative to the axial direction P of the thrust pipe 2 along the track 3431, which can realize the thermal expansion displacement compensation of the passive multi-directional coupling moving support device 3 along the axial direction P of the thrust pipe 2.

[0148] This embodiment, through the specific structure of the movable support device 3, specifically, by setting the adapter 32 to move relative to the fixed base surface 311 of the fixed base 31 along the axial direction P of the thrust pipe 2, it can compensate for the displacement of the tank 11 along the axial direction P of the thrust pipe 2. By setting the anti-friction base 33 to move radially along the tank 11, it can compensate for the radial thermal expansion displacement of the tank 11. The combination of the two can not only simultaneously realize the passive multi-directional coupled displacement movement of the supported equipment (tank 11 and other components), but also has excellent performance such as simple structure, high load-bearing capacity, and stable movement. It has broad application prospects in the field of reliable support for large heavy-duty transportation equipment or special operation equipment (such as nuclear power, aerospace, etc.). By further setting the specific mechanism of the movable support device 3, the passive multi-directional coupled movable support device 3 has a more compact structure, higher movement stability, and longer service life.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
