Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for transporting electrolytic cells, and specifically to a fixture structure for preventing migration and deformation during the transport of electrolytic cells. Background Technology

[0002] Electrolytic cells are the core equipment in the electrolysis process. Their structure is typically large, heavy, complex, with low rigidity, and prone to deformation. During road, sea, or rail transport, the acceleration, deceleration, turning, bumping, and wave action of vehicles or ships generate complex multidimensional dynamic loads, easily causing migration in the forward / backward and lateral directions. Furthermore, impacts can cause shell deformation, affecting subsequent installation and use. Traditional transport securing methods typically use steel wire ropes and chains with simple materials such as timber and rubber pads for binding and support, which are difficult to achieve precise positioning and effective deformation prevention. Moreover, direct binding with steel wire ropes can scratch or damage the anti-corrosion layer on the electrolytic cell surface. The selection of binding points and control of tightness rely on worker experience, resulting in poor reliability. A single securing method cannot meet the transport needs of different models and sizes of electrolytic cells, exhibiting low versatility. Therefore, there is an urgent need for a specialized tooling that can effectively solve the problems of preventing migration and deformation of electrolytic cells during transport, while being easy to operate and highly reliable. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects in the existing technology and provide a tooling structure for preventing migration and deformation during the transportation of electrolytic cells.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A fixture structure for preventing migration and deformation during the transportation of an electrolytic cell includes: The base frame is a rectangular frame structure with multiple locking parts at the bottom that can be detachably connected to the transport carrier. The upper surface of the base frame forms a fixing space for the electrolytic cell. The side limiting mechanism is symmetrically arranged on both sides of the base frame along its length. It includes a sliding guide rail structure, a limiting slider structure, a telescopic top rod structure, and an arc-shaped limiting plate. The sliding guide rail structure and the limiting slider structure cooperate to allow the side limiting mechanism to move flexibly along the axial direction to adjust its position when fixed. One end of the telescopic top rod structure is connected to the limiting slider structure, and the other end is connected to the arc-shaped limiting plate. The arc-shaped limiting plate is attached to the side of the electrolytic cell and forms lateral support for the electrolytic cell through the telescopic top rod structure and the limiting slider structure. The top clamping module includes a portal frame spanning the width of the base frame, a lifting screw, and elastic pressure heads; multiple elastic pressure heads are provided between the inner side of the portal frame and the top of the electrolytic cell, and the elastic pressure heads can adjust the pressure acting on the surface of the electrolytic cell; The multi-level buffer assembly includes a first buffer layer disposed between the upper surface of the base frame and the bottom of the electrolytic cell, and a second buffer layer disposed inside the arc-shaped limiting plate.

[0005] Furthermore, the base frame includes multiple base units, and each base unit has a screw through hole on both sides for bolts to pass through and fix two units together. The base units are spliced ​​together and bolted together. The shape of the base frame can be changed to adapt to different specifications of electrolytic cells. Sliding guide rail structures are set on both sides of the base unit. When the base units are spliced, the sliding guide rail structures are connected and lengthened.

[0006] Furthermore, the locking component at the bottom of the base frame is a flange with positioning holes, which is connected to the pre-embedded nuts of the transport carrier by high-strength bolts, and an anti-loosening gasket is provided between the flange and the base frame.

[0007] Furthermore, the telescopic top rod structure is provided with an adaptive support stiffness structure; the adaptive support stiffness structure includes a magnetorheological cavity set inside the telescopic top rod structure, the magnetorheological cavity is filled with magnetorheological fluid, and an electromagnetic coil is provided at the corresponding position on the side wall of the telescopic top rod structure and the magnetorheological cavity. The current of the electromagnetic coil is controlled to change the viscosity of the magnetorheological fluid, so that the support stiffness of the end of the telescopic top rod is adjustable.

[0008] Furthermore, the adaptive support stiffness structure also includes an airbag mechanism, which includes at least one airbag shell cavity arranged along the axial direction at the bottom of the magnetorheological cavity. The airbag shell cavity is a rigid shell, and an airbag body is provided inside the airbag shell cavity. The airbag body is filled with gas at a preset pressure. A through hole is provided through the side wall of the airbag shell cavity, which connects the inside and outside of the airbag shell cavity. The through hole is a variable diameter hole and is set such that the outer wall hole is smaller than the inner wall hole, so that the resistance of the magnetorheological fluid flowing from the outside to the inside of the airbag shell cavity is greater than the resistance from the inside to the outside.

[0009] Furthermore, at least one tie rod structure is provided between the side of the telescopic top rod structure and the base frame, so that the tie rod structure, the telescopic top rod structure, and the base frame form a triangular stable structure. One end of the pull rod structure is connected to the adjusting sleeve part in the middle of the telescopic top rod through a cross universal joint, and the other end is connected to the ball head base structure on the base frame through a universal ball head. The outer wall of the telescopic top rod structure is provided with external threads. The adjusting sleeve part includes a first threaded sleeve and a second threaded sleeve that are screwed to the external threads. The first threaded sleeve has a cylindrical shaft part on the side near the second threaded sleeve. The adjusting sleeve part also includes a shaft part that is rotatably disposed on the shaft part. A cross universal joint is connected to the outside of the shaft part. The ball head base structure includes two ball head base halves that are spliced ​​together. The two ball head base halves are spliced ​​together to form a complete ball head base, so that the universal ball head can be rotated and set inside the ball head base. The outer wall of the ball head base half is also provided with some threads. The partial threads of the two ball head base halves are spliced ​​together to form a complete thread. A locking nut is provided to be screwed into the complete thread. The lower part of the ball head seat half is provided with a slot that engages with the base frame. The base frame is provided with a first ball head retaining tooth, and the inner wall of the slot is provided with a second ball head retaining tooth that meshes with it. The ball head seat half is inserted into the first ball head retaining tooth to restrict the displacement of the ball head base structure in the length direction. When the two ball head seat half are joined together, they form a clamping limit to fix the displacement of the ball head base structure in the width direction.

[0010] Furthermore, the two side columns of the portal frame span across the two sides of the bottom frame, and their bottoms are detachably connected to the base frame. An arc-shaped pressure plate is provided between the two side columns. The height of the two ends of the arc-shaped pressure plate on the columns is adjustable. An elastic pressure head is provided on the arc-shaped pressure plate. The side of the elastic pressure head facing the electrolytic cell has a groove that matches the curvature of its side wall. The surface of the groove has anti-slip texture. A lifting screw is rotatably provided at the end of the elastic pressure head away from the electrolytic cell. The lifting screw is screwed to the arc-shaped pressure plate.

[0011] Furthermore, the first buffer layer includes a honeycomb rubber pad; The second buffer layer includes a polyurethane foam layer and can be adaptively deformed according to the shape of the side of the electrolytic cell.

[0012] Furthermore, it also includes end positioning mechanisms, which are set at the two shaft ends of the electrolytic cell. The two end positioning mechanisms are clamped on the outside of the end pressure plate of the electrolytic cell to prevent the far end of the electrolytic cell from swinging at the high point. It includes a triangular support frame and an I-beam abutment frame arranged perpendicularly to each other. The bottom of the triangular support frame is detachably fixed on the base frame, and the I-beam abutment frame is set on the right-angle side of the triangular support frame. The I-beam abutment frame is attached to the surface of the end pressure plate.

[0013] Furthermore, a diaphragm pressure sensor is provided on the surface of the component that is in contact with the surface of the electrolytic cell. An acceleration sensor for detecting changes in acceleration along each axis is provided on the electrolytic cell. A data processing unit is also included. The pressure sensor and the acceleration sensor are both connected to the data processing unit to monitor the loosening, over-tightening or abnormal vibration of various parts of the electrolytic cell.

[0014] The advantages and beneficial effects of this utility model are as follows: First, comprehensive rigid constraint provides excellent anti-migration effect: Through the support of the bottom support frame, the clamping of the lateral curvature limiting plates, and the downward pressure of the top crossbeam, a rigid constraint system for the electrolytic cell is formed in three-dimensional space. This effectively resists inertial forces and impacts from all directions (front, back, left, right, up, and down) during transportation, completely preventing equipment migration. Secondly, scientific stress distribution effectively prevents deformation: all clamping and supporting forces are applied to the parts of the electrolytic cell structure with the highest strength (such as near the reinforcing ribs and supports) through pressure blocks with buffer layers, avoiding stress concentration. The support frame evenly supports the bottom, effectively preventing deformation of the bottom plate of the tank due to excessive local stress.

[0015] Third, it is safe and convenient to operate: mechanical adjustment using a top rod and screw is labor-saving and controllable, and the clamping force is uniform, avoiding the problem of inconsistent tightness caused by human factors in traditional binding methods. The buffer layer protects the surface of the equipment.

[0016] Fourth, modular design with strong adaptability: The tooling adopts a modular design, and the number and position of the side clamping modules, as well as the height of the telescopic top rod and lifting screw, are all adjustable. One set of tooling can adapt to the transportation of various models of electrolytic cells within a certain size range, which has good versatility and reduces costs. Fifth, it complies with standard transportation specifications: the bottom frame design allows for direct fixation to standard transportation vehicles, which is convenient, safe, and in line with international transportation practices.

[0018] The specific embodiments of this utility model will be further described below with reference to examples. These examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] Example 1: This utility model discloses a fixture structure for preventing migration and deformation during the transportation of an electrolytic cell, comprising: a base frame 1, wherein the base frame 1 is a rectangular frame structure, and the bottom is provided with at least four locking components that are detachably connected to the transport carrier (specifically, the locking components are flanges with positioning holes, connected to the transport carrier by high-strength bolts and embedded nuts, and anti-loosening gaskets are provided between the flanges and the base frame 1); the upper surface of the base frame 1 is provided with anti-slip protrusions distributed along the length direction (the anti-slip protrusions mainly prevent slippage at the contact point with the bottom surface of the electrolytic cell base, and the anti-slip protrusions adopt a frustum-shaped cone structure to avoid sharp edges from scratching the bottom of the electrolytic cell; preferably, the anti-slip protrusions are distributed along the base frame 1). Along the length direction, a row of protrusions is set every 100-150mm. Along the width direction, 3-5 rows are evenly distributed according to the width of the base frame 1, forming a grid-like layout. The protrusions in adjacent rows are staggered to increase the contact points with the bottom of the electrolytic cell, improve the lateral friction, and further restrict the migration of the electrolytic cell along the length direction. The side limiting mechanism 2 is symmetrically arranged on both sides of the length direction of the base frame 1. Each set of the side limiting mechanism 2 includes a sliding guide rail, a limiting slider, a telescopic top rod, and an arc-shaped limiting plate 6. The sliding guide rail is fixed to the side of the base frame 1. The limiting slider is slidably connected to the sliding guide rail. One end of the telescopic top rod is hinged to the limiting slider, and the other end is fixed to the arc-shaped limiting plate 6.

[0020] As one embodiment of the telescopic top rod structure 5, specifically, the telescopic top rod is equipped with an elastic pin for locking the length. The telescopic top rod has an inner rod and an outer cylinder, and the length adjustment is achieved through the nesting structure of the inner rod and the outer cylinder. The surface of the inner rod has pin holes evenly distributed along the length direction, and the end of the outer cylinder has an elastic pin that matches the pin holes. By locking the pin holes and the elastic pin, the required length can be quickly fixed to meet the limiting distance requirements of different electrolytic cell sides.

[0021] The top clamping mechanism includes a portal frame 7 spanning the width of the base frame 1, a lifting screw 8, and an elastic pressure head 9. The portal frame 7 has two uprights spanning the sides of the bottom frame, with their bottoms detachably connected to the base frame 1 (specifically, a base plate with through holes can be provided at the bottom of the uprights, and corresponding through holes can be provided on the base frame 1 for bolt fastening). A crossbeam is provided at the top of the uprights; an arc-shaped pressure plate 33 is provided between the two uprights, and the height of both ends of the arc-shaped pressure plate 33 on the uprights is adjustable (specifically...). One method involves setting a row of through holes longitudinally on the column, and corresponding through holes at the end of the arc-shaped pressure plate 33. Bolts are inserted into the through holes at different positions to adjust the height of the arc-shaped pressure plate 33. An elastic pressure head 9 is provided on the arc-shaped pressure plate 33. The side of the elastic pressure head 9 facing the electrolytic cell has a groove 34 that matches the curvature of its side wall. The surface of the groove 34 has anti-slip texture. A lifting screw 8 is rotatably provided at the end of the elastic pressure head 9 away from the electrolytic cell. The lifting screw 8 is screwed to the arc-shaped pressure plate 33. The lifting screw 8 is screwed through the threaded through hole and rotatably connected to the elastic pressure head 9. The bottom of the elastic pressure head 9 has a groove 34 that matches the top contour of the electrolytic cell. By rotating the lifting screw 8, the height of the elastic pressure head 9 is adjusted so that the groove 34 presses against the top of the electrolytic cell, limiting vertical displacement. The lifting screw 8 has a self-locking structure design, which can maintain the current position when there is no external driving force. Several elastic pressure heads 9 are distributed on the upper side of the electrolytic cell to position the cell vertically. As an improvement, the elastic pressure head 9 includes a metal shell and an embedded silicone pad, providing a certain amount of buffering and expansion space. The silicone pad is 5-15mm thick and provides buffering and protection during pressure application.

[0022] The multi-level buffer assembly includes a first buffer layer disposed between the top of the base frame 1 and the bottom of the electrolytic cell, and a second buffer layer disposed inside the arc-shaped limiting plate 6. The first buffer layer is a honeycomb rubber pad 35, and the second buffer layer is a polyurethane foam layer 36, and the thickness of both buffer layers is 8-30mm.

[0023] The base frame 1 is welded from Q235 steel, and the frame is provided with transverse reinforcing ribs with a spacing of 300-500mm.

[0024] As needed, the inner width of the base frame 1 matches the bottom width of the electrolytic cell, and its length is 300-500mm longer than the electrolytic cell, reserving installation space for the end positioning mechanism 37. The end positioning mechanism 37 is used to fix the positions of both ends of the electrolytic cell. Secondly, since the bottom of the electrolytic cell is usually more secure than the top, especially when the diameter of the electrolytic cell is too large, its top position is prone to swinging at the far end under inertia, which can cause the electrolytic cell to tilt slightly. Fixing the ends with the end positioning mechanism 37 can effectively prevent the swinging at the far end.

[0025] Preferably, support blocks are installed at the positions corresponding to the reinforcing ribs at the bottom of the electrolytic cell to ensure that the supporting force acts on the rigid parts of the electrolytic cell body.

[0026] Furthermore, the base frame 1 is provided with sliding guide rail structures 3 on both sides along the length of the electrolytic cell, which are rigidly connected to the base frame 1. The length of the guide rail matches the length of the base frame 1, ensuring that the limiting slider can be adjusted in a wide range along the length of the electrolytic cell to adapt to the width requirements of electrolytic cells of different specifications.

[0027] As one embodiment, the sliding guide rail adopts a T-slot or dovetail groove structure, which, in conjunction with the corresponding protrusion of the slider, ensures no lateral offset during sliding and guarantees the positioning accuracy of the limiting mechanism. A gap is reserved between the slider and the guide rail, and the limiting slider is slidably connected to the sliding guide rail. Once in position, it can be quickly fixed by locking bolts. The advantage of using Q235 steel or 45# steel for the sliding guide rail is that it can withstand the lateral compressive force transmitted by the telescopic top rod, avoiding deformation.

[0028] Preferably, the number of the side limiting mechanisms 2 is at least two sets, symmetrically arranged on the left and right sides of the bottom support frame, with one set every 600mm along the length direction.

[0029] As one of the preferred embodiments of the side limiting mechanism 2 in this example, the curvature of the limiting plate is designed according to the side profile of a common electrolytic cell, and the edge of the limiting plate is provided with a rounded transition structure. The second buffer layer (polyurethane foam layer 36) on its inner side can be slightly deformed according to the shape of the side of the electrolytic cell, increasing the contact area while avoiding scratches caused by hard contact. Specifically, one end of the telescopic top rod structure 5 is hinged to the limiting slider structure 4, and the other end is fixed to the arc-shaped limiting plate 6.

[0030] As an improvement, the two side columns of the portal frame 7 are provided with height adjustment grooves. By using bolts to cooperate with multiple adjustment holes on the base frame 1, the height of the portal frame 7 can be adjusted in a step manner, thus making it suitable for fixing electrolytic cells of different specifications.

[0031] Furthermore, the first buffer layer between the top of the base frame 1 and the bottom of the electrolytic cell is a honeycomb rubber pad 35. Appropriately filling the gap between the bottom of the electrolytic cell and the base frame 1 with this first buffer layer can reduce the gap and prevent objects from shaking in the buffer layer.

[0032] Depending on the needs and the characteristics of the electrolytic cell, the first buffer layer can be made of a suitable material. For example, a velvet material can be used for easily scratched surfaces, while a more elastic foam can be used for fragile items. It can directly contact the surface of the object without causing scratches or wear, and at the same time has a certain degree of toughness, which can initially absorb minor external vibrations or impacts.

[0033] Preferably, the second buffer layer on the inner side of the arc-shaped limiting plate 6 is a polyurethane foam layer 36, and the thickness of the buffer layer is 8-30mm. The buffer layer can be slightly deformed according to the shape of the side of the electrolytic cell, increasing the contact area while avoiding scratches caused by hard contact.

[0034] As needed, the thickness or density of the second buffer layer can be adjusted according to the intensity of bumps and collisions in the transportation or storage scenario, taking into account the buffering needs of different degrees of external forces, while also being able to fill the gap between the electrolytic cell and the arc-shaped limiting plate 6.

[0035] Preferably, all metal parts of the tooling are subjected to anti-corrosion treatment (such as hot-dip galvanizing or spraying with anti-corrosion paint).

[0036] A fixture structure for preventing migration and deformation during the transportation of an electrolytic cell includes the following steps: (1) Tooling pretreatment: Check whether the base frame 1, the lateral positioning component and the top clamping device are intact and the buffer layer is undamaged; (2) Electrolytic cell placement: Use a forklift to place the electrolytic cell stably in the center of the base frame 1, ensuring that the bottom of the cell is in complete contact with the base buffer layer; (3) Lateral limiting: Move the slider and telescopic top rod adjustment mechanism in sequence to make the lateral arc-shaped limiting plate 6 fit against the side of the electrolytic cell until all limiting plates are subjected to stable pre-tightening force; and install the end positioning mechanism 37. (4) Top clamping: Lower the top pressure head to contact the preset force point on the top of the electrolytic cell, and adjust the pressure to the set value (determined according to the weight and material characteristics of the electrolytic cell). (5) Fixing inspection: Confirm that the electrolytic cell is not loose in the front-back, left-right, and up-down directions, the buffer layer is tightly attached, and the tooling and transport vehicle are fixed by the bottom bolts (pre-set bolt holes in the base frame 1).

[0037] Example 2: The base frame 1 includes multiple base units 10. In Embodiment 1, the base frame 1 can be understood as an integral structure, the size of which needs to be manufactured according to different models of electrolytic cells. In this embodiment, it is improved to a modular structure. It is understood that electrolytic cells usually have many different length specifications due to the variation in the number of electrode layers. In this embodiment, the base frame 1 is divided into several base units 10 that are spliced ​​and lengthened. Therefore, the number of base units 10 can be flexibly increased or decreased according to the length of the electrolytic cell, thus facilitating adaptation. As shown in the figure, sliding guide rails are still provided on both sides of the base unit 10 along the length direction of the electrolytic cell. On both sides of the electrolytic cell width direction, screw through holes 11 are respectively provided. When two base units 10 are connected, the screw through holes 11 correspond to each other. The bolts pass through the screw through holes 11 and are fixed to splice and fix the two units. The base units 10 are spliced ​​and bolted together. The shape of the base frame 1 is changed to adapt to different specifications of electrolytic cells. Sliding guide rail structures 3 are provided on both sides of the base unit 10. When the base units 10 are spliced, the sliding guide rail structures 3 are connected and lengthened. Both sections of the sliding guide rail structures 3 on both sides of the unit are open. Therefore, when the units are spliced, the sliding guide rail structures 3 automatically lengthen, which facilitates the smooth movement of the side limiting structure between different units.

[0038] Specifically, as one embodiment of the sliding guide rail structure 3, it includes a track groove, and a positioning rack 40 is provided on the inner bottom wall of the track groove; the limiting slider structure 4 includes a slider part 43 that is slidably connected to the track groove, and a hinge seat 41 that is connected to the side limiting mechanism 2. The slider part 43 is provided with a fixing strip on the side facing the positioning rack 40. When the fixing strip engages with the positioning rack 40, it fixes the position of the limiting slider structure 4. The two ends of the fixing strip are provided with springs 42 that push it away from the positioning rack 40. The slider part 43 is screwed with a strip push rod 44. The strip push rod 44 can be a screw, that is, rotating the strip push rod 44 pushes the fixing strip and compresses the spring 42, so that the fixing strip is engaged in the positioning rack 40 to form a fixation.

[0039] Example 3: Traditional telescopic top rods have fixed support stiffness, which cannot cope with the problems of "variable bump intensity and dynamic changes in the force on the electrolytic cell" during transportation. If the stiffness is insufficient, the electrolytic cell is prone to shaking and migration; if the stiffness is excessive, the cell is prone to local deformation due to impact loads. This embodiment achieves real-time adaptive adjustment of the support stiffness through the combination of "magnetorheological cavity 12 + airbag mechanism 14".

[0040] The telescopic top rod structure 5 is equipped with an adaptive support stiffness structure. The adaptive support stiffness structure includes a magnetorheological cavity 12 set inside the telescopic top rod structure 5, which is filled with magnetorheological fluid. An electromagnetic coil 13 is provided at the corresponding position on the side wall of the telescopic top rod structure 5 and the magnetorheological cavity 12. The current of the electromagnetic coil 13 is controlled to change the viscosity of the magnetorheological fluid, so that the support stiffness of the end of the telescopic top rod is adjustable.

[0041] In practical use, when the transport vehicle (such as a truck or ship) experiences slight bumps, the lateral pressure of the electrolytic cell on the telescopic push rod is relatively small. At this time, the control system outputs a low current, and the electromagnetic coil 13 generates a weak magnetic field. Magnetic particles in the magnetorheological fluid only slightly aggregate, and the fluid viscosity is low, allowing the telescopic push rod to deform slightly, absorbing minor vibrations and avoiding rigid impacts. When encountering strong loads such as sharp turns or wave impacts, the lateral thrust of the electrolytic cell increases sharply. After detecting the pressure / acceleration change, the control system immediately increases the current, and the electromagnetic coil 13 generates a strong magnetic field. Magnetic particles in the magnetorheological fluid rapidly align along the magnetic field direction to form a "chain-like structure," and the fluid transforms into a semi-solid state. The support stiffness of the telescopic push rod increases synchronously, firmly restricting the displacement of the electrolytic cell and preventing migration. The stiffness adjustment response is fast (millisecond level), and the stiffness change is continuously controllable, precisely matching the support requirements under different impact intensities and avoiding the contradiction of "too rigid and easily damaged, too flexible and easily wobbled."

[0042] The adaptive support stiffness structure also includes an airbag mechanism 14. The airbag mechanism 14 includes at least one airbag shell cavity 15 arranged along the axial direction at the bottom of the magnetorheological cavity 12. The airbag shell cavity 15 is a rigid shell, and an airbag body 16 is provided inside the airbag shell cavity 15. The airbag body 16 is filled with gas at a preset pressure. A through hole 17 is provided through the side wall of the airbag shell cavity 15, and the through hole 17 connects the inside and outside of the airbag shell cavity 15. The through hole 17 is a variable diameter hole and is set such that the outer wall hole 18 is smaller than the inner wall hole 19, so that the resistance of the magnetorheological fluid flowing from the outside to the inside of the airbag shell cavity 15 is greater than the resistance from the inside to the outside.

[0043] Specifically, the airbag mechanism 14 does not work independently, but serves as an auxiliary buffer unit for the magnetorheological cavity 12. It addresses the issues of the hysteresis in the magnetorheological fluid regulation (although it is at the millisecond level, pre-buffering is still required under extreme impact) and the adaptation to the minute deformation of the electrolytic cell. The specific structure and principle are as follows: Airbag shell 15: A rigid shell arranged along the axis at the bottom of the magnetorheological cavity 12 (to prevent the airbag from rupturing under pressure), with a variable-diameter through hole 17 penetrating through the side wall (the diameter of the outer wall hole 18 is smaller than the diameter of the inner wall hole 19, forming a unidirectional flow resistance structure). Airbag body 16: An elastic airbag placed inside the shell cavity, pre-filled with gas at a set pressure (e.g., 0.3-0.5 MPa, the pressure is preset according to the weight of the electrolytic cell), in direct contact with the magnetorheological fluid.

[0044] Buffer pre-adaptation: During installation before transportation, the airbag 16 is kept in an expanded state due to the pre-pressurized gas. It squeezes the magnetorheological fluid through the through hole 17, so that the magnetorheological fluid forms an initial pressure in the cavity. This applies a slight pre-tightening force to the electrolytic cell in advance, avoiding "gap shaking" in the early stage of transportation.

[0045] Unidirectional flow resistance adaptation: When the electrolytic cell is squeezed towards the telescopic push rod due to impact (i.e., the push rod is under pressure), the magnetorheological fluid needs to flow into the air bladder cavity 15. However, due to the small outer wall hole 18 and large inner wall hole 19 of the through hole 17, the fluid flow resistance is large. At this time, the air bladder body 16 is only slightly compressed, mainly relying on the stiffness of the magnetorheological fluid to resist the impact. When the impact load weakens and the electrolytic cell has a tendency to rebound (the push rod pressure decreases), the pre-pressurized gas in the air bladder pushes the magnetorheological fluid to flow outward. The resistance of the through hole 17 is small, and the fluid flow quickly resets, so that the push rod always fits against the side of the electrolytic cell, avoiding the "rebound gap". Key function: Through the "unidirectional flow resistance" design, "resistant to deformation under pressure and quick reset under pressure" is achieved, forming a "rigid-flexible synergy" with the magnetorheological cavity 12, which not only ensures the stiffness under strong impact, but also improves the dynamic adaptability.

[0046] At least one tie rod structure 20 is provided between the side of the telescopic top rod structure 5 and the base frame 1, so that the tie rod structure 20, the telescopic top rod structure 5, and the base frame 1 form a stable triangular structure. In this embodiment, preferably, two tie rod structures 20 are provided on one side of the telescopic top rod structure 5, thereby forming a three-dimensional stable triangular pyramid structure. It can be understood that providing one tie rod structure 20 is feasible, and its advantage is that it occupies less space in the length direction of the electrolytic cell, and it only forms a triangular structure, which has good stability in the plane, but lacks lateral stiffness in space. The improved use of two tie rod structures 20 can provide better lateral stiffness for the telescopic top rod structure 5. To allow the combination of the pull rod structure 20 and the telescopic top rod structure 5 to have a certain adjustment range, thus adapting to the fixing of electrolytic cells of different diameters, one end of the pull rod structure 20 is connected to the adjusting sleeve part in the middle of the telescopic top rod via a universal joint 21, and the other end is connected to the ball head base structure on the base frame 1 via a universal ball joint; thus, universal connections are formed at both ends of the pull rod structure 20, which is particularly suitable for use when two pull rod structures 20 are set; furthermore, the outer wall of the telescopic top rod structure 5 is provided with an external thread 22, and the adjusting sleeve part includes the external thread 22. The first threaded sleeve 23 and the second threaded sleeve 24 are screwed together. The first threaded sleeve 23 has a cylindrical shaft part 25 on the side near the second threaded sleeve 24. The adjusting sliding sleeve part also includes a bushing part 26 rotatably mounted on the shaft part 25. A cross universal joint 21 is connected to the outside of the bushing part 26. In actual use, the connection position of the bushing part 26 on the telescopic top rod structure 5 can be adjusted by rotating the first threaded sleeve 23 and the second threaded sleeve 24, which can effectively adjust the pulling and supporting force of the pull rod structure 20. The bushing part 26 can provide the pull rod structure 20 with a degree of freedom to rotate around the telescopic top rod structure 5.

[0047] Furthermore, the ball head base structure includes two opposing ball head base halves 27, which are joined together to form a complete ball head base, allowing the universal ball head to rotate within the ball head base. The outer wall of the ball head base half 27 is also provided with partial threads 28, and the partial threads 28 of the two ball head base half 27 are joined together to form a complete thread. A locking nut 29 is screwed into the complete thread. In this embodiment, the ball head base structure is an assembled structure, which can be easily added when fixing the electrolytic cell. In addition, the universal joint 21 at the other end can also be detachably connected, so that a tie rod structure 20 can be easily added when needed. The upper part of the ball head seat plate of this structure is divided into two opposing halves along the diameter longitudinal direction. When the universal ball head is clamped on both sides, a universal ball connection can be easily formed. In order to maintain the stability of the ball head seat, the two ball head seat plates are joined together and locked with locking nuts 29 to keep the ball head seat intact and fixed. During assembly, the locking nuts 29 can be put on the universal ball head first, and then the ball head seat plate can be inserted into the appropriate position on the base frame 1 for fixation (the position of the ball head seat structure relative to the length direction of the electrolytic cell can be fixed by inserting the locking slot part at the bottom of the ball head seat into the locking teeth on the base frame 1).

[0048] Specifically, the lower part of the ball joint half 27 is provided with a slot 30 that engages with the base frame 1. The base frame 1 is provided with a first ball joint tooth 31, which is a tooth arranged along the length of the electrolytic cell on the base frame 1. The inner wall of the slot 30 is provided with a second ball joint tooth 32 that meshes with it. When the slot 30 is engaged on the base frame 1, the two ball joint teeth mesh with each other, thereby positioning the ball joint base structure. Specifically, the ball joint half 27 is engaged in the first ball joint tooth 31 to restrict the displacement of the ball joint base structure in the length direction. When the two ball joint half 27 are joined together, they form a clamping limit, fixing the displacement of the ball joint base structure in the width direction, thereby positioning the bottom of the tie rod structure 20.

[0049] Example 4: The end positioning mechanism 37 is set at the two shaft ends of the electrolytic cell. The two end positioning mechanisms 37 are clamped on the outside of the end pressure plate of the electrolytic cell to prevent the far end of the electrolytic cell from swinging at the high point. It includes a triangular support frame 38 and an I-beam abutment frame 39 arranged perpendicularly to each other. The bottom of the triangular support frame 38 is detachably fixed on the base frame 1. The I-beam abutment frame 39 is set on the right-angle side of the triangular support frame 38. The I-beam abutment frame 39 is attached to the surface of the end pressure plate.

[0050] This embodiment focuses on the problem of "end-end swaying" during the transportation of electrolytic cells. By adding an end positioning mechanism 37, it fills the gap in traditional tooling that only focuses on "bottom support, lateral clamping, and top pressing" while neglecting "shaft end constraint". This mechanism addresses the structural characteristics of electrolytic cells, which have "high bottom fixing strength and are prone to swaying due to inertia at the top", and achieves rigid limiting of the electrolytic cell shaft end through a combination design of "triangular support frame 38 + I-beam abutment frame 39", avoiding tilting or local deformation caused by end-end swaying during transportation.

[0051] As a long and precise piece of equipment, the electrolytic cell exhibits a significant difference in rigidity: the bottom, being in direct contact with the base frame 1, is strongly supported and constrained, resulting in a low risk of displacement; while the top (especially the high point at the shaft end) is far from the fixed point, and during transportation (such as sudden braking, turning, or ship swaying), it is prone to "swinging around the far end of the bottom support point" due to inertia. This swaying may not only cause the electrolytic cell to tilt as a whole, but may also cause uneven stress on the end pressure plate at the shaft end (a key component for sealing and bearing weight at the end of the electrolytic cell), leading to local deformation or seal failure.

[0052] Principle: When the transport vehicle brakes or accelerates suddenly, the electrolytic cell will experience "back-and-forth movement" (axial displacement) along its length due to inertia. At this time, the end pressure plate at the shaft end will directly press against the I-beam abutment frame 39. Since the I-beam abutment frame 39 is rigidly connected to the triangular support frame 38, and the triangular support frame 38 is fixed to the base frame 1, a force transmission path of "end pressure plate → I-beam abutment frame 39 → triangular support frame 38 → base frame 1" is formed, distributing the axial inertial force to the base frame 1 and the transport vehicle, preventing the electrolytic cell from migrating axially. Key function: By replacing the traditional "flexible binding" with "rigid blocking," it can withstand greater axial impact force (according to material strength calculations, the triangular support frame 38 made of Q235 steel can withstand an axial force of 5-10kN, far exceeding the binding constraint force of traditional steel wire ropes), and will not loosen due to long-term stress.

[0053] Example 5: A diaphragm-type pressure sensor 46 is installed on the surface of the component in contact with the surface of the electrolytic cell. An acceleration sensor 45 is installed on the electrolytic cell to detect changes in acceleration along various axes. A data processing unit is also included. Both the pressure sensor 46 and the acceleration sensor 45 are connected to the data processing unit to monitor for looseness, excessive tightness, or abnormal vibration in various parts of the electrolytic cell. Specifically, the arc-shaped limiting plate 6 is the direct contact component between the side limiting mechanism 2 and the side of the electrolytic cell. The sensors need to be attached to the inner side of the arc-shaped limiting plate 6 (in contact with or embedded in the second buffer layer polyurethane foam layer 36), and are evenly distributed along the length of the arc-shaped limiting plate 6. At least 2-3 sensors are installed on each arc-shaped limiting plate 6 (for example, one sensor at each end and one in the middle of a 1m long arc-shaped plate) to ensure coverage of the main stress areas on the side of the electrolytic cell. The supporting pressure of the side limiting mechanism 2 on the side of the electrolytic cell is acquired in real time to determine whether there is "insufficient pressure (easily leading to migration)" or "pressure overload (easily leading to cell deformation)".

[0054] The elastic pressure head 9 is the contact component between the top clamping module and the top of the electrolytic cell. A diaphragm-type pressure sensor 46 is embedded in the bottom of each elastic pressure head 9 (i.e., within the groove 34 facing the electrolytic cell, synchronously fitting with the anti-slip texture). This sensor works in conjunction with the buffer structure of the elastic pressure head 9 to prevent the sensor from directly bearing rigid impacts. It senses the magnitude of the top clamping force, ensuring that the pressure meets the requirement of "limiting vertical displacement" without exceeding the pressure-bearing limit of the top structure of the electrolytic cell (e.g., to avoid damaging the top anti-corrosion layer or weak components).

[0055] The I-beam abutment bracket 39 is attached to the outer side of the electrolytic cell end plate. The sensor needs to be embedded in the contact surface of the I-beam abutment bracket 39 (in conjunction with the rubber buffer layer). Two I-beam abutment brackets 39 are arranged for each piece (one on the top and one on the bottom), covering the main stress area of ​​the end plate. The end positioning mechanism 37 determines the constraint pressure on the electrolytic cell shaft end to prevent the end plate from swinging due to insufficient pressure or deforming due to excessive pressure. Accelerometer 45 senses the multidimensional dynamic acceleration of the electrolytic cell during transportation and determines whether there is an impact or vibration that exceeds the safe range. At least one "three-axis accelerometer 45" (which can simultaneously monitor the acceleration changes in the X, Y, and Z axes) is deployed.

[0056] The diaphragm pressure sensor 46 converts "contact pressure" into an electrical signal (such as a voltage or current signal), which is transmitted to the data processing unit via a wire (or wireless module). The acquisition frequency is set to 1 time / second to ensure real-time tracking of pressure changes (such as instantaneous pressure fluctuations during transport). The triaxial accelerometer 45 converts "multidimensional acceleration" into a digital signal and transmits it to the data processing unit. The acquisition frequency is set to 10 times / second to accurately capture short-term impacts (such as the acceleration peak within 0.5 seconds during emergency braking). The data processing unit has a built-in "safety threshold database." The data processing unit compares the real-time acquired pressure and acceleration data with preset thresholds to determine the stationary state of the electrolytic cell. When the pressure is less than the minimum safe pressure: output "loosening warning", indicating that the restraint pressure on the side or top needs to be increased; When the pressure exceeds the maximum safe pressure: output an "over-tightening warning" to indicate that the constraint pressure needs to be reduced; When the acceleration exceeds the safety threshold, an "abnormal vibration warning" is output, indicating that the support stiffness of the side limiting mechanism 2 needs to be adjusted (in conjunction with the adaptive support structure of Embodiment 3) to cope with the impact load.

[0057] (a) Adjustments to the "loosening warning": Extend the telescopic top rod to increase lateral pressure. When the diaphragm pressure sensor 46 detects that "the side contact pressure is less than the minimum safe pressure" (e.g., due to slight rebound of the push rod caused by transportation bumps, the pressure drops to 0.15 MPa), the data processing unit outputs an "elongation adjustment command". The adjustment process is as follows: Mechanical adjustment: The telescopic top rod structure 5 can adopt a threaded telescopic top rod: the control motor drives the outer cylinder of the top rod to rotate, and the inner rod extends through the threaded transmission. The pressure change is monitored in real time, and the rotation stops after the target pressure is reached, so as to achieve precise extension.

[0058] Combined with stiffness adjustment: If there is a slight acceleration fluctuation (not exceeding the threshold) at the same time, while the push rod is extended, the data processing unit controls the electromagnetic coil 13 of the side telescopic push rod to increase the current slightly (e.g., from 0.5A to 0.8A). By increasing the viscosity of the magnetorheological fluid, the support stiffness is slightly enhanced, and the pressure is prevented from dropping again due to vibration after extension.

[0059] (ii) Adjustments to address the "over-tightening warning": shorten the telescopic jack to reduce lateral pressure. When pressure sensor 46 detects that "side contact pressure > maximum safe pressure" (e.g., the push rod is overextended during initial adjustment, and the pressure rises to 1.2 MPa), the data processing unit outputs a "shortening adjustment command." The adjustment process is as follows: Mechanical adjustment (thread type): Controls the motor to rotate in the opposite direction, driving the inner rod to retract, monitoring the pressure in real time, and stopping when the target is reached.

[0060] Buffering and Coordination Adjustment: If the excessive tightness is caused by "stable transport load but excessively high initial pressure setting", while shortening the top rod, the magnetorheological coil current can be slightly reduced (e.g., from 1.0A to 0.7A) to reduce the support stiffness and avoid excessive rigid constraints that could lead to local stress concentration on the side of the electrolytic cell.

[0061] (iii) Adjustments for “abnormal vibration warning”: Adjust the support stiffness, rather than simply changing the length. When the accelerometer 45 detects "acceleration > safety threshold" (e.g., X-axis acceleration reaches 1.8g during emergency braking), the data processing unit outputs a "stiffness adjustment command," adjusting the side support stiffness based on the "magnetorheological cavity 12 + airbag mechanism 14" in Embodiment 3, rather than simply changing the length of the push rod (to avoid pressure fluctuations caused by frequent length adjustments). The adjustment process is as follows: The stiffness of the magnetorheological cavity 12 is improved: the data processing unit increases the current of the electromagnetic coil 13 (e.g., from 0.8A to 2.0A), which causes the magnetic particles of the magnetorheological fluid to quickly form a "chain structure", significantly increasing the viscosity. The support stiffness of the telescopic top rod is simultaneously enhanced (e.g., from 10kN / m to 50kN / m) to resist impact loads and reduce the lateral swaying of the electrolytic cell. Airbag mechanism 14 auxiliary buffer: Under impact load, magnetorheological fluid flows into the airbag shell cavity 15 (due to the one-way flow resistance of the through hole 17, the flow resistance is large), and the airbag body 16 is slightly compressed to absorb part of the impact energy and avoid rigid impact caused by sudden increase in stiffness. Vibration recovery: When the acceleration drops below the safety threshold, the data processing unit reduces the current of the electromagnetic coil 13, the viscosity of the magnetorheological fluid decreases, and the support stiffness returns to the normal level (e.g., 10kN / m). At the same time, the airbag 16 pushes the magnetorheological fluid to reset through the pre-pressurized gas, ensuring that the top rod always fits against the side of the electrolytic cell and the pressure remains within the safe range.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
