Description

Technical Field

[0001] This application relates to the field of electrolytic cell leveling technology, and in particular to a leveling device and a leveling apparatus for an electrolytic cell stack. Background Technology

[0002] In large-scale alkaline or proton exchange membrane electrolysis water production systems, the electrolyzer is usually precisely stacked from hundreds of bipolar plates, gaskets, and end plates. The levelness of the electrolyzer assembly plane directly affects the equipment's sealing performance, stress uniformity, and operational stability, requiring high precision in assembly and leveling.

[0003] In existing technologies, electrolytic cell leveling devices mostly employ manual adjustment or simple multi-point support structures, which generally suffer from low leveling accuracy and poor adjustment efficiency. During actual assembly, due to unevenness of the base platform, the electrolytic cell is prone to tilting in its initial installation state, which can damage the cell's sealing structure and affect the safe and stable operation of the equipment. Summary of the Invention

[0004] The purpose of this application is to provide a leveling device for an electrolytic cell stack, which can achieve precise leveling of the support platform, ensure that the assembly plane of the electrolytic cell stack is in a horizontal state, and ensure assembly accuracy and sealing reliability.

[0005] In a first aspect, the present invention provides a leveling device for an electrolytic cell stack, comprising: Chassis; A support frame is rotatably mounted on the chassis; A support platform is located above the support frame and spaced apart from the support frame; the support platform is used to support the electrolytic cell stack. The leveling mechanism includes at least five independent lifting components, each of which is circumferentially spaced around the support platform. One end of each lifting component is connected to the support frame, and the other end is connected to the support platform. Each lifting component is driven independently to raise or lower the corresponding position of the support platform relative to the support frame, thereby leveling the support platform.

[0006] Beneficial Effects: This electrolytic cell stack leveling device places the electrolytic cell stack onto a support platform during operation. Since the support frame can rotate relative to the chassis, circumferential rotation positioning of the support platform and the electrolytic cell stack is achieved. During the leveling process, adjustment is achieved through at least five independently configured lifting components. These components are spaced apart circumferentially around the support platform, and each component can be driven independently, raising and lowering the corresponding position of the support platform relative to the support frame. By independently controlling the lifting stroke of each component, the height of different positions on the support platform can be individually adjusted, thereby correcting tilt caused by unevenness of the base platform. This achieves precise leveling of the support platform, ensuring the assembly plane of the electrolytic cell stack is horizontal, and guaranteeing assembly accuracy and sealing reliability.

[0007] By employing at least five independent lifting components arranged circumferentially around the support platform, each lifting component can be driven independently and its lifting stroke adjusted individually. This enables precise compensation for local tilting caused by unevenness of the base platform, achieving fine adjustment of the support platform at multiple points and in multiple postures. This effectively improves the levelness of the assembly plane of the electrolytic cell stack, enhances the overall leveling accuracy, and prevents deformation or displacement of the electrolytic cell stack due to local stress concentration. It also makes components such as bipolar plates and sealing gaskets fit more tightly and bear more consistent force, thereby improving the sealing reliability of the electrolytic cell after assembly.

[0008] In addition, the automatic adjustment of multiple independent lifting components replaces the traditional manual adjustment or simple support adjustment method. It eliminates the need for repeated manual calibration and auxiliary support, and can quickly complete the posture alignment and level adjustment of the bearing platform, effectively shortening the assembly and debugging time of the electrolytic cell and improving the assembly operation efficiency.

[0009] In one optional embodiment, the lifting assembly includes a drive unit and a push rod. The drive unit is disposed on the support frame. One end of the push rod is connected to the drive unit and the other end is connected to the bearing platform. The drive unit is used to drive the push rod to lift and lower, thereby causing the corresponding position of the bearing platform to rise and fall.

[0010] Beneficial effects: The lifting assembly adopts a direct-acting structure with a drive unit and push rod. The drive unit is directly connected to the push rod, resulting in a short transmission chain and fewer intermediate links. This avoids the gaps, errors, and failure points caused by complex transmission mechanisms, making the lifting motion of the push rod more stable and smooth. It ensures that the load-bearing platform does not shake, jam, or deviate during the leveling process, resulting in high overall operational reliability.

[0011] In one optional implementation, the drive unit is a lead screw assembly; The push rod is coaxially arranged with the lead screw of the lead screw assembly. The bottom of the push rod has a sleeve hole and is sleeved on the lead screw through the sleeve hole. The bottom of the push rod is connected to the lead screw nut of the lead screw assembly.

[0012] Beneficial effects: The lead screw assembly is a precision transmission mechanism that achieves linear motion through the meshing of the lead screw and lead screw nut. It has high transmission accuracy and accurate positioning, and can realize minute height adjustment of the bearing platform, thereby accurately compensating for tilt errors caused by unevenness of the base platform, and significantly improving the levelness and leveling accuracy of the assembly plane of the electrolytic cell stack.

[0013] In one optional embodiment, the bottom of the support platform is provided with a plurality of connectors, each connector being correspondingly provided with a push rod of each lifting assembly, and the top of the connector and the push rod are connected by a spherical joint.

[0014] Beneficial effects: During the leveling process, the load-bearing platform will tilt and deflect relative to the support frame. The push rod and the load-bearing platform are connected by a spherical pair, which can adaptively compensate for the angle deviation, so that the push rod always bears only axial force and not radial bending moment, lateral force and torsional force. This fundamentally avoids jamming, jamming, wear or damage of the lifting components, and ensures smooth and reliable leveling action.

[0015] In one optional embodiment, the leveling device further includes a plurality of detection units, each detection unit being configured corresponding to the lifting assembly, and the detection unit being used to detect the height of the bearing platform at the corresponding lifting assembly.

[0016] Beneficial effects: Each detection unit is set up one-to-one with each lifting component, enabling real-time and independent detection of the actual height of the support platform at each support point, obtaining height data from multiple points rather than a single location. Multi-point detection can comprehensively reflect the spatial attitude, tilt angle, and levelness of the support platform, providing accurate and complete data support for high-precision leveling.

[0017] In one alternative implementation, the lifting components and the detection units are arranged along the same horizontal circumference.

[0018] Beneficial effects: The lifting components and the detection unit are arranged on the same horizontal circumference, so that the detection point coincides with or corresponds in height to the support point. The detection unit can directly and accurately reflect the height and posture of the bearing platform at the actual support position, avoiding detection errors caused by misalignment between the detection point and the support point, and ensuring accurate and reliable height data.

[0019] In one optional embodiment, the leveling device further includes a rotating mechanism for driving the support frame to rotate; The rotating mechanism includes an external gear ring and a drive assembly. The external gear ring is fixed on the chassis, and the drive assembly is mounted on the support frame. The gear of the drive assembly meshes with the external gear ring. The drive assembly drives the gear to rotate around the external gear ring, thereby causing the support frame to rotate around the axis of the external gear ring.

[0020] Beneficial effects: The external gear ring is fixed to the chassis and forms an external meshing gear transmission with the gear of the drive component. It has high meshing rigidity and a large bearing area, and can withstand large radial forces, circumferential forces and overturning moments. When supporting large and heavy electrolytic cell stacks, it can still drive the support frame to rotate smoothly and reliably, ensuring stable and safe rotation.

[0021] In one alternative embodiment, the drive assembly is provided with a plurality of gears, and the gears of each drive assembly are arranged circumferentially around the external gear ring.

[0022] Beneficial effects: Multiple drive components are evenly arranged along the circumference of the external gear ring, allowing driving force to act simultaneously and symmetrically on the external gear ring from multiple directions. This ensures balanced force distribution and uniform torque distribution on the support frame, avoiding uneven load, swaying, and vibration caused by single-sided drive, resulting in a smoother and more stable rotation process. Furthermore, multiple drive components can output torque synchronously, easily driving the rotation of heavy-duty support frames that support large electrolytic cell stacks, solving problems such as insufficient torque, inability to drive, and easy slippage associated with single drive.

[0023] In one optional embodiment, the leveling device further includes a support locking structure, which is disposed between the support frame and the bearing platform, and the support locking structure has a supported state and a released state. When the load-bearing platform is leveled, the support locking structure is in a released state to allow the load-bearing platform to adjust its posture; after the load-bearing platform is leveled, the support locking structure switches from the released state to the supported state, and the support locking structure supports the middle area of ​​the load-bearing platform.

[0024] Beneficial effects: During leveling, the support locking structure is in a released state, providing no support force to the load-bearing platform, ensuring that the platform can freely adjust its posture. The high-precision adjustment of the lifting components is unrestricted, ensuring leveling accuracy. After leveling, it switches to the support state, providing stable support to the load-bearing platform. Leveling is flexible, positioning is stable, and the two states do not conflict with each other.

[0025] In one optional embodiment, the leveling device further includes a plurality of locking rods and a plurality of locking mechanisms, wherein each locking rod is circumferentially spaced around the bearing platform, and the locking mechanism is fixedly mounted on the support frame, and each locking rod is correspondingly arranged with each locking mechanism. One end of each locking rod is located on the bearing platform, and the other end passes through the corresponding through hole of the support frame; When the bearing platform is leveled, the locking end of the locking mechanism separates from the corresponding locking rod; after the bearing platform is leveled, the locking end of the locking mechanism locks with the corresponding locking rod.

[0026] Beneficial effects: During the leveling process, the locking mechanism separates from the locking rod, freeing the bearing platform from any constraint on its posture. This allows the bearing platform to tilt and rise freely without affecting the leveling accuracy. After leveling is complete, the locking mechanism reliably locks the locking rod, making the bearing platform and support frame a rigid whole, with a fixed posture that does not wobble or shift, achieving high-precision leveling and high-rigidity locking.

[0027] Secondly, the present invention also provides a leveling device, comprising: Chassis; A support frame is rotatably mounted on the chassis; A support platform is positioned above and spaced apart from the support frame, and the support platform is used to support the part to be leveled. The leveling mechanism includes at least five independent lifting components, each of which is circumferentially spaced around the support platform. One end of each lifting component is connected to the support frame, and the other end is connected to the support platform. Each lifting component is driven independently to raise or lower the corresponding position of the support platform relative to the support frame, thereby leveling the support platform.

[0028] Beneficial effects: This leveling device has the same leveling effect as the leveling device for the electrolytic cell stack because the leveling device has the same structure, so it will not be described in detail here. Attached Figure Description

[0032] In related technologies, electrolytic cell leveling devices often employ manual adjustment or simple multi-point support structures, which generally suffer from low leveling accuracy and poor adjustment efficiency. During actual assembly, uneven base platforms can easily cause the electrolytic cell to tilt during initial installation, thereby damaging its sealing structure and affecting the safe and stable operation of the equipment.

[0033] During the research and development process of this application, in order to keep the assembly plane of the electrolytic cell stack horizontal and ensure assembly accuracy and sealing reliability, the research and development team initially used airbags in conjunction with guide columns for assisted alignment. Through the flexible adjustment of the airbags and the guiding constraint of the guide columns, the horizontal orientation of the assembly plane of the electrolytic cell stack can be adjusted within a certain range, achieving preliminary alignment and leveling functions.

[0034] Further testing and verification revealed certain shortcomings in the aforementioned solution. The airbag itself has relatively weak structural rigidity, making it prone to compression deformation and insufficient support stability under heavy loads from stacked electrolytic cells. As the electrolytic cell stack is assembled and loaded at each stage, the assembly plane is prone to tilting or sinking, making it difficult to maintain a stable horizontal posture under heavy loads and failing to meet the requirements for high-precision and high-stability assembly. Therefore, this application proposes corresponding improvement solutions.

[0035] Based on this, the inventors of this application have redesigned the leveling device for the electrolytic cell stack. When the leveling device is in operation, the electrolytic cell stack is placed on a support platform. Since the support frame can rotate relative to the chassis, circumferential rotational positioning of the support platform and the electrolytic cell stack can be achieved. During the leveling process of the support platform, adjustment is achieved through at least five independently configured lifting components. Each lifting component is arranged circumferentially around the support platform, and each lifting component can be driven independently, raising and lowering the corresponding position of the support platform relative to the support frame. By independently controlling the lifting stroke of each lifting component, the height of different positions on the support platform can be adjusted individually, thereby correcting the tilt caused by unevenness of the base platform, achieving precise leveling of the support platform, ensuring that the assembly plane of the electrolytic cell stack is in a horizontal state, and ensuring assembly accuracy and sealing reliability.

[0036] By employing at least five independent lifting components arranged circumferentially around the support platform, each lifting component can be driven independently and its lifting stroke adjusted individually. This enables precise compensation for local tilting caused by unevenness of the base platform, achieving fine adjustment of the support platform at multiple points and in multiple postures. This effectively improves the levelness of the assembly plane of the electrolytic cell stack, enhances the overall leveling accuracy, and prevents deformation or displacement of the electrolytic cell stack due to local stress concentration. It also makes components such as bipolar plates and sealing gaskets fit more tightly and bear more consistent force, thereby improving the sealing reliability of the electrolytic cell after assembly.

[0037] In addition, the automatic adjustment of multiple independent lifting components replaces the traditional manual adjustment or simple support adjustment method. It eliminates the need for repeated manual calibration and auxiliary support, and can quickly complete the posture alignment and level adjustment of the bearing platform, effectively shortening the assembly and debugging time of the electrolytic cell and improving the assembly operation efficiency.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0039] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0040] According to embodiments of the present invention, such as Figures 1 to 8 As shown, on one hand, a leveling device for an electrolytic cell stack is provided, including a chassis 100, a support frame 200, a bearing platform 300, and a leveling mechanism 400.

[0041] Specifically, such as Figures 1 to 3 As shown, the support frame 200 is mounted on the chassis 100, and the support frame 200 is rotatable on the chassis 100.

[0042] Specifically, such as Figures 1 to 3 As shown, the support platform 300 is installed above the support frame 200, and the support platform 300 and the support frame 200 are spaced apart. The support platform 300 is used to support the electrolytic cell stack. When installing the electrolytic cell stack, the electrolytic cell stack can be installed on the support platform 300, using the support platform 300 as the base platform.

[0043] Specifically, such as Figures 1 to 5 As shown, the leveling mechanism 400 includes at least five lifting components 410, which are spaced apart circumferentially around the support platform 300. One end of each lifting component 410 is connected to the support frame 200, and the other end is connected to the support platform 300. Furthermore, each lifting component 410 of the leveling mechanism 400 is independently driven. By independently driving each lifting component 410, the corresponding position of the support platform 300 is raised or lowered relative to the support frame 200, thereby achieving leveling of the support platform 300.

[0044] This electrolytic cell stack leveling device places the electrolytic cell stack onto the support platform 300 during operation. Since the support frame 200 can rotate relative to the chassis 100, circumferential rotational positioning of the support platform 300 and the electrolytic cell stack is achieved. During the leveling process of the support platform 300, adjustment is performed using at least five independently configured lifting components 410. Each lifting component 410 is arranged circumferentially around the support platform 300, and each lifting component 410 can be driven independently, raising and lowering the corresponding position of the support platform 300 relative to the support frame 200. By independently controlling the lifting stroke of each lifting component 410, the height of different positions of the support platform 300 is individually adjusted, thereby correcting the tilt caused by unevenness of the base platform, achieving precise leveling of the support platform 300, ensuring that the assembly plane of the electrolytic cell stack is in a horizontal state, and ensuring assembly accuracy and sealing reliability.

[0045] By employing at least five independent lifting components 410 arranged circumferentially around the support platform 300, each lifting component 410 can be driven independently and its lifting stroke can be adjusted individually. This allows for precise compensation for local tilting caused by unevenness of the base platform, enabling fine adjustment of the support platform at more than 300 points and in multiple postures. This effectively improves the levelness of the assembly plane of the electrolytic cell stack, enhances the overall leveling accuracy, and prevents deformation or displacement of the electrolytic cell stack due to local stress concentration. It also makes the components such as bipolar plates and sealing gaskets fit more tightly and bear more consistent force, thereby improving the sealing reliability of the electrolytic cell after assembly.

[0046] In addition, multiple independent lifting components 410 are automatically adjusted to replace the traditional manual adjustment or simple support adjustment method. Without the need for repeated manual calibration and auxiliary support, the posture alignment and level adjustment of the bearing platform 300 can be completed quickly, effectively shortening the assembly and debugging time of the electrolytic cell and improving the assembly operation efficiency.

[0047] It should be noted that if the leveling mechanism 400 has only four lifting components 410, the four lifting components 410 can only roughly adjust the overall tilt of the bearing platform 300, and it is difficult to compensate for errors caused by local unevenness, foundation settlement, and local deformation. At least five lifting components 410 can independently control the height of more points, and can finely correct the slight tilt and local deviation of the platform, making the assembly surface of the electrolytic cell stack flatter and more precise.

[0048] Specifically, multiple independent lifting components 410 can operate individually or in combination, enabling the bearing platform to achieve more than 300 degrees of freedom and multi-angle attitude adjustment, which can adapt to the assembly needs of electrolytic cells of different specifications and under different working conditions, making it more widely applicable and more practical.

[0049] Specifically, at least five lifting components 410 can be evenly distributed on the same horizontal circumference, forming a regular polygonal distribution. Alternatively, they can be distributed in concentric circles. In this embodiment, no specific restrictions are placed on the distribution of the multiple lifting components 410.

[0050] For example, the leveling mechanism 400 has five lifting components 410, which are distributed on the same horizontal circumference, and the five points form a regular pentagon.

[0051] Specifically, the support frame 200 is rotatably mounted on the chassis 100. The support frame 200 can rotate on the chassis 100 via a gear 621 ring gear mechanism, or via a gear 621 rack, worm gear, or other mechanisms. In this embodiment, no specific restrictions are placed on the rotation method of the support frame 200.

[0052] Specifically, the lifting assembly 410 can be an electric telescopic rod, an electric cylinder, a pneumatic cylinder, a gear and rack mechanism, etc. In this embodiment, the type of lifting assembly 410 is not specifically limited.

[0053] Specifically, during the leveling process of the bearing platform 300, the support frame 200 can serve as a stable installation benchmark and reference plane. Since the support frame 200 itself maintains a constant posture, each lifting component 410 independently adjusts its lifting stroke at the corresponding position with the support frame 200 as a unified reference benchmark. This precisely controls the height and tilt angle of the bearing platform 300 relative to the support frame 200, effectively eliminating installation errors caused by unevenness of the foundation platform and ensuring a stable leveling process and accurate leveling results.

[0054] In one embodiment, such as Figure 4 and Figure 5 As shown, the lifting assembly 410 includes a drive unit 411 and a push rod 412. The drive unit 411 is mounted on the support frame 200. One end of the push rod 412 is connected to the drive unit 411, and the other end is connected to the bearing platform 300. The drive unit 411 drives the push rod 412 to move up and down, thereby causing the corresponding position of the bearing platform 300 to move up and down relative to the support frame 200.

[0055] The lifting assembly 410 adopts a direct-acting structure with a drive unit 411 and a push rod 412. The drive unit 411 is directly connected to the push rod 412, resulting in a short transmission chain and fewer intermediate links. This avoids the gaps, errors, and failure points caused by complex transmission mechanisms, making the lifting movement of the push rod 412 more stable and smooth. It ensures that the load-bearing platform 300 does not shake, jam, or deviate during the leveling process, resulting in high overall operational reliability.

[0056] The drive unit 411 directly drives the push rod 412 to perform linear telescopic motion, which can precisely control the extension length and positioning position of the push rod 412, realize the minute height adjustment of the corresponding position of the bearing platform 300, thereby accurately compensating for the tilt error caused by the unevenness of the base platform, improving the levelness and leveling accuracy of the assembly plane of the electrolytic cell stack, and helping to ensure the sealing performance of the electrolytic cell.

[0057] The push rod 412 directly bears the load of the bearing platform 300 and the electrolytic cell stack in a linear support manner. The force form is reasonable and the support stiffness is high. When bearing large and heavy electrolytic cell stacks, it is not easy to bend or elastically deform, and can provide stable and reliable support for the bearing platform 300.

[0058] In addition, the drive unit 411 is mounted on the support frame 200, and the push rod 412 is arranged vertically and directly connected to the bearing platform 300. The overall structure is simple, compact and occupies little space. It is convenient to arrange at least five lifting components 410 around the bearing platform 300 to achieve multi-point uniform support and adjustment. At the same time, it is convenient for the overall assembly, wiring and subsequent maintenance of the device.

[0059] Specifically, the drive unit 411 can be a motor, cylinder, hydraulic cylinder, etc. In this embodiment, the type of drive unit 411 is not specifically limited.

[0060] Specifically, the push rod 412 can be set vertically or at an angle. In this embodiment, there are no specific restrictions on the setting of the push rod 412.

[0061] For example, taking the push rod 412 as a vertical setting, the vertically set push rod 412 can provide more stable support for the bearing platform 300 compared with the inclined push rod 412. At the same time, during the lifting and lowering process of the push rod 412, the lifting and lowering stroke of the push rod 412 can directly reflect the lifting and lowering stroke of the corresponding position of the bearing platform 300.

[0062] In one embodiment, such as Figure 4 and Figure 5 As shown, the drive unit 411 is a lead screw assembly 4111, wherein the push rod 412 is coaxially arranged with the lead screw of the lead screw assembly 4111, and the bottom of the push rod 412 has a sleeve hole 4121, through which the push rod 412 is sleeved on the lead screw. The bottom of the push rod 412 is connected to the lead screw nut 41112 of the lead screw assembly 4111.

[0063] The lead screw assembly 4111 is a precision transmission mechanism. It achieves linear motion through the meshing of the lead screw and the lead screw nut 41112. It has high transmission accuracy and accurate positioning. It can realize the minute height adjustment of the bearing platform 300, thereby accurately compensating for the tilt error caused by the unevenness of the base platform and significantly improving the levelness and leveling accuracy of the assembly plane of the electrolytic cell stack.

[0064] The push rod 412 is coaxially set with the lead screw. The push rod 412 is sleeved on the outside of the lead screw through the sleeve hole 4121, so that the lifting and lowering movement of the push rod 412 is consistent with the transmission center of the lead screw. The movement trajectory is straight and does not deviate, which effectively ensures that the bearing platform 300 is raised and lowered smoothly during the leveling process and avoids shaking, tilting or jamming.

[0065] In addition, the lead screw assembly 4111 has a mechanical self-locking characteristic. After the drive unit 411 stops working, the lead screw nut 41112 can automatically lock in the current position, so that the push rod 412 and the bearing platform 300 maintain a fixed posture and will not sink or shift on their own due to the load, ensuring long-term stability of the posture after leveling.

[0066] Specifically, such as Figure 5 As shown, the lead screw 41111 can be mounted on the support frame 200 via the support base 41113. When the push rod 412 is driven to move up and down, the lead screw can be driven to rotate by a servo motor and a reducer, causing the lead screw nut 41112 to move along the axial direction of the lead screw. Since the lead screw nut 41112 is connected to the bottom of the push rod 412, when the lead screw nut 41112 moves along the axial direction of the lead screw, the lead screw nut 41112 will also drive the push rod 412 to move up and down.

[0067] In one embodiment, such as Figure 4 and Figure 5As shown, the bottom of the support platform 300 is provided with multiple connectors 310, each connector 310 is correspondingly provided with the push rod 412 of each lifting component 410, and the top of the connector 310 and the push rod 412 are connected by a spherical pair 311.

[0068] During the leveling process, the bearing platform 300 will tilt and deflect relative to the support frame 200. The push rod 412 is connected to the bearing platform 300 through the spherical pair 311, which can adaptively compensate for the angle deviation, so that the push rod 412 always only bears the axial force and does not bear the radial bending moment, lateral force and torsional force, fundamentally avoiding the lifting component 410 from jamming, getting stuck, wearing or being damaged, and ensuring that the leveling action is smooth and reliable.

[0069] The spherical pair 311 has the characteristics of self-alignment and adaptive angle. When the bearing platform 300 is tilted and adjusted, it will not generate internal stress, assembly stress or local deformation due to the rigid connection forcibly constraining the angle. It can effectively avoid stress transmission to the bearing platform 300, thereby preventing uneven force on the electrolytic cell stack and deformation of the sealing surface under pressure, and improving assembly quality and sealing reliability.

[0070] The spherical pair 311 is a surface contact with a large contact area and low stress. Under heavy load conditions, it can uniformly transfer the load, ensuring the stable support of the lifting component 410 for the bearing platform 300, reducing the likelihood of local stress concentration, and improving the service life and stability of the overall structure.

[0071] Specifically, such as Figure 5 As shown, the connector 310 has a spherical groove, and the top of the push rod 412 has a raised spherical surface. The raised spherical surface on the top of the push rod 412 is connected and fitted with the spherical groove on the connector 310 to form a spherical pair 311 connection.

[0072] In one embodiment, such as Figure 1 and Figure 4 As shown, the leveling device also includes multiple detection units 500, each detection unit 500 being correspondingly arranged with the lifting assembly 410. The detection unit 500 is used to detect the height of the supporting platform 300 at the corresponding lifting assembly 410.

[0073] Each detection unit 500 is set up one-to-one with each lifting component 410, enabling real-time and independent detection of the actual height of the bearing platform 300 at each support point, obtaining height data from multiple points rather than single-position detection. Multi-point detection can comprehensively reflect the spatial attitude, tilt angle, and levelness of the bearing platform 300, providing real and complete data support for high-precision leveling.

[0074] The detection unit 500 collects height signals in real time and feeds them back to the control system. It works in conjunction with each lifting component 410 to form a multi-point closed-loop servo control. The system can adjust the stroke of the corresponding lifting component 410 individually based on the difference between the measured height and the target height at each point, achieving rapid correction, significantly reducing leveling errors, and improving leveling accuracy and consistency.

[0075] Specifically, multi-point real-time height detection enables fully automatic leveling without the need for manual measurement or calibration, reducing the intensity of manual operation and human error, improving assembly efficiency, and making it more suitable for automated and high-precision assembly scenarios of large electrolytic cell stacks.

[0076] Specifically, the detection unit 500 can be a laser displacement sensor, an ultrasonic sensor, etc. In this embodiment, the type of detection unit 500 is not specifically limited.

[0077] In one embodiment, such as Figure 1 As shown, each lifting component 410 and the detection unit 500 are arranged along the same horizontal circumference.

[0078] The lifting assembly 410 and the detection unit 500 are arranged on the same horizontal circumference, so that the detection point coincides with or corresponds in height to the support point. The detection unit 500 can directly and accurately reflect the height and posture of the bearing platform 300 at the actual support position, avoiding detection errors caused by misalignment of the detection point and the support point, and ensuring accurate and reliable height data.

[0079] In one embodiment, such as Figure 8 As shown, the leveling device also includes a rotating mechanism 600, which drives the support frame 200 to move on the chassis 100. The rotating mechanism 600 includes an external gear ring 610 and a drive assembly 620. The external gear ring 610 is fixed to the chassis 100, and the drive assembly 620 is mounted on the support frame 200. The gear 621 of the drive assembly 620 meshes with the external gear ring 610. The drive assembly 620 rotates around the external gear ring 610 via the drive gear 621, causing the support frame 200 to rotate around the axis of the external gear ring 610.

[0080] The external gear ring 610 is fixed on the chassis 100 and forms an external meshing gear 621 transmission with the gear 621 of the drive assembly 620. It has high meshing rigidity and a large bearing area, and can withstand large radial forces, circumferential forces and overturning moments. When carrying large and heavy electrolytic cell stacks, it can still drive the support frame 200 to rotate smoothly and reliably, ensuring the stability and safety of the rotation process.

[0081] The gear 621 and the external gear ring 610 are rigidly meshed, with no backlash or relative slippage. This allows for precise control of the rotation angle of the support frame 200, enabling small-angle fine-tuning and accurate circumferential positioning. This meets the requirements for multi-angle docking and precise alignment of the electrolytic cell during assembly, improving assembly efficiency and accuracy.

[0082] In one embodiment, such as Figure 8 As shown, the drive assembly 620 has multiple components, and the gears 621 of each drive assembly 620 are arranged circumferentially around the outer gear ring 610.

[0083] Multiple drive components 620 are evenly arranged circumferentially along the outer gear ring 610. The driving force acts on the outer gear ring 610 simultaneously and symmetrically from multiple directions, ensuring that the support frame 200 is subjected to balanced force and uniform torque distribution. This avoids the uneven load, swaying, and vibration caused by unilateral drive, resulting in a smoother and more stable rotation process. Furthermore, the multiple drive components 620 can output torque synchronously, easily driving the heavy-duty support frame 200 that supports large electrolytic cell stacks to rotate, solving problems such as insufficient torque, inability to drive, and easy slippage caused by single drive.

[0084] The rotational driving force is shared by multiple gears 621. Each gear 621 bears less force, the tooth surface wear is more uniform, the impact is less, the fatigue wear of the drive component 620 is reduced, and the overall service life of the gears 621, the outer gear ring 610 and the drive unit 411 is extended.

[0085] Specifically, multiple drive components 620 are provided, providing redundant drive capability. Even if one drive component 620 temporarily malfunctions, the remaining drive components 620 can still maintain the normal rotation of the support frame 200, ensuring that the device operates without interruption and improving the stability and safety of equipment operation.

[0086] In one embodiment, such as Figure 8 As shown, the leveling device also includes a support and locking structure 700, which is disposed between the support frame 200 and the bearing platform 300. The support and locking structure 700 has a supported state and a released state. When the bearing platform 300 is leveled, the support and locking structure 700 is in the released state, and at this time, the support and locking structure 700 does not provide support force to the bearing platform 300, ensuring that the bearing platform 300 can adjust its posture. After the bearing platform 300 is leveled, the support and locking structure 700 switches from the released state to the supported state. At this time, the support and locking structure 700 provides support force to the bearing platform 300, supporting the middle area of ​​the bearing platform 300.

[0087] During the leveling process, the support locking structure 700 is in a released state, providing no support force to the load-bearing platform 300, ensuring that the load-bearing platform 300 can freely adjust its posture. The high-precision adjustment of the lifting component 410 is unrestricted, ensuring leveling accuracy. After leveling is completed, it switches to the support state, providing stable support to the load-bearing platform 300. The leveling is flexible and the positioning is stable, with the two states not conflicting with each other.

[0088] During the leveling process, the support locking structure 700 supports the load-bearing platform 300 without generating additional constraint forces, local stresses, or assembly stresses on the load-bearing platform 300. This avoids problems such as twisting of the load-bearing platform 300 caused by rigid support, ensuring smooth and unobstructed leveling. After leveling, the support locking structure 700 supports the middle area of ​​the load-bearing platform 300, forming multi-point support with the circumferential lifting component 410, significantly improving the overall rigidity of the load-bearing platform 300 and preventing deflection, deformation, and vibration in the middle area of ​​the platform due to heavy loads.

[0089] Specifically, for the large-size, heavy-weight support platform 300 used in large electrolytic cell stacks, relying solely on the circumferential lifting assembly 410 can easily lead to sagging in the middle and insufficient rigidity. The central support locking structure 700 can effectively overcome the deformation of the support platform 300, ensure the flatness of the support platform 300, and meet the assembly and use requirements of heavy load, high precision, and large size.

[0090] Specifically, the support locking structure 700 can be an electric support column, a hydraulic support cylinder, a pneumatic support cylinder, etc. In this embodiment, the type of support locking structure 700 is not specifically limited.

[0091] like Figures 9 to 14 As shown, a support and locking structure 700 includes a base 710, a cylinder 720, a locking member 730, and a support member 740.

[0092] Specifically, such as Figures 9 to 12 As shown, the base 710 is provided with a receiving cavity 711, which is used to receive the rotating end 741 of the support member 740.

[0093] Specifically, such as Figures 9 to 13 As shown, the cylinder body 720 is mounted on the base 710. The cylinder body 720 has an internal mounting groove 721 that communicates with the receiving cavity 711. The cylinder body 720 also has a through hole 722 that extends along the height of the cylinder body 720 and communicates with the mounting groove 721.

[0094] Specifically, such as Figure 12 and Figure 13 As shown, the locking member 730 is movably disposed in the mounting groove 721 of the cylinder body 720, and the locking member 730 can be driven to move in the mounting groove 721 by the driving mechanism.

[0095] Specifically, such as Figures 9 to 14 As shown, the support member 740 includes a rotating end 741 and a supporting end 742. The rotating end 741 is rotatably mounted within the receiving cavity 711, and the outer wall surface of the rotating end 741 is formed into an arc shape. The supporting end 742 of the support member 740 passes through the through hole 722 and extends to the outside of the cylinder body 720, allowing the supporting end 742 of the support member 740 to be connected to an external support platform or other components to be connected.

[0096] Specifically, such as Figures 9 to 14 As shown, the support locking structure 700 has a released state and a supported state. When the support locking structure 700 is in the released state, an external force drives the supporting end 742 of the support member 740, causing the rotating end 741 of the support member 740 to rotate adaptively within the receiving cavity 711. When the support locking structure 700 switches from the released state to the supported state, a drive mechanism drives the locking member 730 to move toward the rotating end 741, so that the locking member engages with the rotating end 741, thereby restricting the rotation of the rotating end 741.

[0097] When the external support platform undergoes attitude adjustment (such as leveling), the support locking structure 700 is in a released state. When an external force is applied to the support end 742, because the rotating end 741 is rotatably located within the receiving cavity 711 and its outer wall surface is arc-shaped, the support member 740 can freely rotate relative to the base 710 and the cylinder body 720 with the rotating end 741 as the center, achieving adaptive angle adjustment. At this time, the support member 740 rotates with the platform tilting without generating additional bending moment, ensuring the smoothness and accuracy of platform leveling.

[0098] When the platform needs to be locked after attitude adjustment, the drive mechanism is activated, driving the locking member 730 to move along the mounting groove 721 toward the rotating end 741. As the locking member 730 approaches, it engages with the rotating end 741, restricting its rotational freedom. At this time, the support locking structure 700 is in a supported state, and the support member 740 is rigidly locked in its current attitude, providing stable support for the platform and enabling it to maintain its attitude during subsequent heavy-duty operations (such as electrolytic cell stacking). When the platform's attitude needs to be readjusted, the drive mechanism reverses and drives the locking member 730 back, disengaging it from the rotating end 741. The structure returns to its released state, and the support member 740 regains its rotational freedom.

[0099] Because the rotating end 741 of the support member 740 adopts an arc-shaped surface design and is rotatably located in the receiving cavity 711, when the bearing platform is adjusted in attitude, the support member 740 can adaptively rotate with the tilt of the platform, effectively avoiding the additional bending moment caused by the inability to follow the movement, thereby preventing motion jamming and structural wear, improving leveling accuracy and extending the service life of the equipment.

[0100] In the supported state, the locking component 730 closely cooperates with the rotating end 741 through the drive mechanism, restricting the rotational freedom of the rotating end 741, and can reliably lock the bearing platform in the target posture. Even if heavy-load stacking or high-torque assembly operations are carried out later, it can provide high rigidity support, effectively resist overturning moment, and ensure assembly accuracy.

[0101] In the released state, the support member 740 is allowed to rotate freely, providing flexibility for precise leveling of the support platform; in the supported state, automatic locking can be achieved without manual intervention. The movement of the locking member 730 is controlled by a drive mechanism (such as hydraulic or pneumatic), which facilitates integration into automated production lines and enables precise monitoring and closed-loop control of the locking force.

[0102] Specifically, the drive mechanism can be a hydraulic drive mechanism, a pneumatic drive mechanism, or an electric push rod drive mechanism, etc. In this embodiment, no specific limitation is made on the type of drive mechanism.

[0103] Specifically, the outer wall surface of the rotating end 741 is set as an arc-shaped surface, mainly to enable the support member 740 to freely and adaptively rotate in a single-point / small-area contact manner when released, thereby achieving flexible adjustment of the support angle. The arc-shaped surface ensures that the support member 740 always maintains smooth contact with the inner wall surface of the receiving cavity 711 during deflection, without any jamming or jamming, while avoiding the generation of additional bending moments, stress concentrations, or structural interference. The arc-shaped surface allows the rotating end 741 to adaptively deflect in any direction within the receiving cavity 711, which can match the multi-dimensional attitude changes of the bearing platform during the leveling process, ensuring smooth, stable, and high-precision leveling.

[0104] If the outer wall of the rotating end 741 adopts a non-arc structure such as a plane, square, or rectangle, the rotating end 741 cannot rotate smoothly in the receiving cavity 711, and it is easy to get stuck at the corners and have its movement blocked, making it impossible to achieve self-adaptive leveling; the support 740 and the receiving cavity 711 are in rigid surface contact, and cannot deflect with the tilt of the platform, which will generate a large additional bending moment, resulting in uneven force on the components and increased wear.

[0105] Specifically, the locking member 730 and the rotating end 741 can be engaged by abutment engagement, snap-lock engagement, etc. In this embodiment, no specific restrictions are placed on the engagement method between the locking member 730 and the rotating end 741.

[0106] In one embodiment, such as Figure 12 and Figure 13 As shown, the inner wall of the mounting groove 721 and the locking member 730 enclose a pressure chamber 7211. The cylinder body 720 is provided with a fluid interface 723. One end of the fluid interface 723 is connected to the pressure chamber 7211, and the other end of the fluid interface 723 is connected to the drive mechanism.

[0107] The inner wall of the mounting groove 721 and the locking element 730 enclose a pressure chamber 7211, which can directly use hydraulic oil or compressed air as the driving medium to drive the locking element 730 to achieve linear motion through fluid pressure, without the need for additional complex transmission components such as motors, lead screws, and gears. Integrating the driving chamber with the cylinder body 720 and the locking element 730 into one unit makes the overall structure more compact and simple, effectively reducing the number of parts and assembly difficulty, and improving structural reliability.

[0108] By using fluid pressure to drive the movement of the locking component 730, the driving force is transmitted smoothly with minimal impact, avoiding vibration and noise caused by mechanical transmission. By adjusting the fluid pressure entering the pressure chamber 7211, the locking force of the locking component 730 on the rotating end 741 of the support component 740 can be flexibly and precisely controlled. This not only meets the high rigidity locking requirements under heavy-duty conditions but also avoids component deformation or damage due to excessive locking force, thus expanding the applicability of the structure.

[0109] Specifically, the fluid-driven response is fast. When pressurized fluid is introduced into the fluid interface 723, the pressure in the pressure chamber 7211 rises rapidly, quickly pushing the locking element 730 towards the rotating end 741 to achieve abutment and locking, meeting the operational cycle requirements of rapid leveling and rapid locking in automated production lines. At the same time, the fluid has good pressure-holding performance, maintaining the locking force continuously under supported conditions, ensuring stable locking without loosening or rebound.

[0110] In one embodiment, such as Figure 12 and Figure 13 As shown, the abutment end 731 of the locking member 730 is configured as an arc-shaped surface, wherein the arc-shaped surface of the abutment end 731 is adapted to the arc-shaped surface of the rotating end 741. When the supporting locking structure 700 is in the supported state, the abutment end 731 of the locking member 730 abuts and engages with the rotating end 741.

[0111] The abutting end 731 of the locking member 730 adopts an arc-shaped surface, which is adapted to the arc-shaped surface of the rotating end 741. In the supported state, it can achieve a surface-to-surface contact, increasing the contact area between the locking member 730 and the rotating end 741. Compared with point contact or line contact locking methods, this structure can effectively disperse contact stress, avoid excessive local stress causing component damage, and improve the stability and reliability of locking.

[0112] The mutually adaptable arc-shaped surfaces can form an automatic centering and self-adaptive alignment effect when they abut and fit together, making the fit between the locking component 730 and the rotating end 741 more precise. After locking, it can effectively limit the rotation, swaying and radial movement of the support component 740, ensuring that the support component 740 is stably locked in the target posture, avoiding problems such as posture deviation and loosening under heavy load, impact or eccentric load, and improving the overall support accuracy.

[0113] The close contact between the curved surfaces creates a circumferential locking effect, effectively resisting the circumferential force, overturning moment, and lateral load generated by the support component 740 during operation, providing higher rigidity support for the bearing platform. Especially under conditions such as electrolytic cell stacking and heavy-duty assembly, it can ensure the stability of the bearing platform's posture, improving the overall operational accuracy and safety of the equipment.

[0114] In one embodiment, such as Figure 12 and Figure 13 As shown, the locking member 730 has a first stepped surface 732 surrounding its periphery, and the inner wall of the mounting groove 721 has a second stepped surface 7212. The first stepped surface 732 and the second stepped surface 7212 are correspondingly arranged. When the supporting locking structure 700 is in the supported state, the first stepped surface 732 of the locking member 730 and the second stepped surface 7212 of the mounting groove 721 abut against each other.

[0115] The locking member 730 is provided with a first stepped surface 732, and the inner wall of the mounting groove 721 is provided with a corresponding second stepped surface 7212. In the supported state, the two abut against each other, which can accurately limit the movement stroke of the locking member 730 and avoid problems such as excessive insertion, jamming, or over-rushing of the locking member 730 due to excessive pressure or assembly errors, thus ensuring that the locking member 730 moves within a safe and reasonable range.

[0116] By positioning the first step surface 732 and the second step surface 7212, the locking member 730 can be limited after moving to the preset position each time, ensuring that the mating position between the abutting end 731 of the locking member 730 and the rotating end 741 of the support member 740 is stable and has high repeatability, avoiding situations where the locking is not in place or there is excessive interference due to inconsistent stroke, and improving the consistency and reliability of the structure operation.

[0117] In addition, when the first step surface 732 and the second step surface 7212 are in contact with each other, an auxiliary sealing surface can be formed on one side of the pressure chamber 7211, which enhances the sealing effect of the pressure chamber 7211, reduces fluid medium leakage, improves driving efficiency, and at the same time prevents external impurities from entering the pressure chamber 7211, ensuring the long-term stable operation of the drive mechanism.

[0118] Specifically, the first step surface 732 and the second step surface 7212 can be set as a plane or an inclined plane. In this embodiment of the application, the structure of the first step surface 732 and the second step surface 7212 is not specifically limited.

[0119] In one embodiment, such as Figures 12 to 14 As shown, the support member 740 also includes a connecting section 743, which is disposed between the rotating end 741 and the supporting end 742, and passes through the through hole 722. A movable gap is reserved between the outer wall surface of the connecting section 743 and the inner wall surface of the through hole 722, which is used to avoid rotational offset of the support member 740.

[0120] The reserved clearance between the outer wall of the connecting section 743 and the inner wall of the through hole 722 provides sufficient clearance for the adaptive deflection of the support 740, ensuring that the connecting section 743 will not contact, rub or interfere with the inner wall of the through hole 722 when the support 740 is adjusting its attitude with the bearing platform, thus ensuring that the support 740 rotates smoothly without jamming.

[0121] The clearance can also compensate for dimensional errors, coaxiality errors and positional deviations generated during the processing and assembly of the connecting section 743 and the through hole 722, reducing the stringent requirements for the processing and assembly accuracy of parts, reducing processing difficulty and scrap rate, and helping to improve production efficiency and reduce manufacturing costs.

[0122] In one embodiment, such as Figures 12 to 14 As shown, the support member 740 also includes a transition section 744, one end of which is used for connection to the support end 742, and the other end is connected to the connecting section 743. Along the axial direction of the support member 740, the diameter of the transition section 744 gradually decreases from top to bottom.

[0123] The transition section 744, with its smooth structure of gradually changing diameter, smoothly transitions the diameter change between the support end 742 and the connecting section 743, avoiding abrupt sharp angles. This effectively disperses the stress generated by the support member 740 when it is subjected to heavy loads, eccentric loads, and overturning moments, preventing fractures or deformations caused by stress concentration and improving the structural strength and service life of the support member 740.

[0124] Meanwhile, the transition section 744, whose diameter gradually decreases from top to bottom, has a larger cross-sectional size near the support end 742, which can provide higher structural rigidity and better withstand the pressure of the top bearing platform; while the size near the connecting section 743 is smaller, which can reduce the overall weight and achieve a balance between rigidity and lightweight, making it more suitable for heavy-duty support conditions.

[0125] Furthermore, the transition section 744 adopts a tapered structure that gradually decreases in size from top to bottom along the axial direction of the support member 740, which can create an outwardly expanding clearance space between the support end 742 and the connecting section 743. When the support member 740 rotates adaptively, the transition section 744 will not collide or interfere with the upper end of the through hole 722 of the cylinder block 720, ensuring that the support member 740 has a larger deflection angle and smoother movement.

[0126] In one embodiment, such as Figure 12 and Figure 13 As shown, the cylinder body 720 includes a sleeve 724 and an end cap 725, wherein the end cap 725 covers the top of the sleeve 724, and the locking member 730 is movably disposed inside the sleeve 724 and coaxially disposed with the sleeve 724.

[0127] The cylinder block 720 adopts a separate structure with sleeve 724 and end cover 725, which can be machined independently, reducing the overall machining difficulty and precision requirements. At the same time, during assembly, internal parts such as locking component 730 can be installed into sleeve 724 first, and then end cover 725 can be assembled, which facilitates the installation, debugging and subsequent maintenance of the internal structure, effectively improving production and maintenance efficiency.

[0128] The split structure of the cylinder body 720 facilitates the formation of a sealed pressure chamber 7211 between the sleeve 724 and the locking element 730. After the end cover 725 is closed, the sealing performance of the pressure chamber 7211 can be further improved, reducing hydraulic oil or compressed air leakage, ensuring stable output of driving force of the drive mechanism, and ensuring reliable operation of the locking element 730.

[0129] In addition, the locking element 730 is arranged coaxially with the sleeve 724, which allows the locking element 730 to move linearly along the central axis of the sleeve 724 under the action of the drive mechanism. The movement direction is precise and the force is uniform, avoiding problems such as uneven wear, excessive lateral force or movement jamming, and improving the stability of the movement of the locking element 730 and the service life of the structure.

[0130] Specifically, the end cap 725 and the sleeve 724 can be connected by bolts or other connecting parts. In this embodiment, the connection method between the end cap 725 and the sleeve 724 is not specifically limited.

[0131] In one embodiment, such as Figure 9 , Figure 10 and Figure 14As shown, a first positioning pin 7421 is provided on the support end 742, wherein the first positioning pin 7421 can be disposed in the middle region of the support end 742. A plurality of first connecting holes 7422 are provided around the periphery of the support end 742. And / or, a second positioning pin 712 is provided at the bottom of the base 710, and the second positioning pin 712 can be disposed in the middle region of the base 710. A plurality of second connecting holes 713 are provided around the periphery of the bottom of the base 710.

[0132] The first positioning pin 7421 and the second positioning pin 712 can respectively realize the pre-positioning of the support end 742 with the external bearing platform and the base 710 with the mounting surface, ensuring that the center position is quickly aligned during installation, avoiding repeated adjustments during assembly, and significantly improving assembly efficiency and positional accuracy.

[0133] Both the support end 742 and the bottom of the base 710 employ multiple connecting holes arranged around their perimeter, which ensures even distribution of locking and supporting forces and avoids localized stress concentration. Simultaneously, in conjunction with the locating pins, this significantly improves the structure's resistance to torsion and shear, meeting the requirements for heavy-load, high-overturning-moment applications such as electrolytic cell stacking.

[0134] In one embodiment, such as Figure 12 and Figure 13 As shown, a seal (not shown) is provided between the locking member 730 and the pressure chamber 7211.

[0135] A seal is provided between the locking element 730 and the inner wall of the pressure chamber 7211 to effectively seal the leakage gap of hydraulic oil or compressed air, ensuring that the pressure chamber 7211 establishes a stable and sufficient driving pressure during pressurization, avoiding insufficient driving force, weak locking or slow action due to fluid leakage, and ensuring the normal operation of the drive mechanism.

[0136] In the supported state, the seal can maintain the pressure holding performance of the pressure chamber 7211, prevent the pressure in the pressure chamber from slowly decaying and causing the locking to loosen, and ensure that the locking member 730 continuously and reliably abuts against the rotating end 741 of the support member 740, so that the support posture remains stable for a long time under heavy load conditions.

[0137] Specifically, the sealing element can be an annular sealing ring, such as an O-ring or a stepped sealing ring. In this embodiment, no specific limitation is made on the type of sealing element.

[0138] Specifically, the seals typically have good lubrication compatibility, which can form a lubricating film between the locking element 730 and the cavity wall, reducing the frictional resistance of the locking element 730 during linear movement, making the movement smoother and more stable, reducing component wear, and improving the structural operational stability.

[0139] In one embodiment, combined Figure 1 , Figure 6 and Figure 7 As shown, the leveling device also includes multiple locking rods 800 and multiple locking mechanisms 900. The locking rods 800 are spaced apart circumferentially around the support platform 300, and the locking mechanisms 900 are fixedly mounted on the support frame 200, with each locking rod 800 corresponding to one locking mechanism 900. One end of each locking rod 800 is mounted on the support platform 300, and the other end passes through a corresponding through hole 210 on the support frame 200. When the support platform 300 is leveled, the locking end 910 of the locking mechanism 900 separates from the corresponding locking rod 800, allowing the locking rod 800 to move up and down with the support platform 300. After the support platform 300 is leveled, the locking end 910 of the locking mechanism 900 locks the corresponding locking rod 800, preventing the locking rod 800 from moving freely.

[0140] During the leveling process, the locking mechanism 900 separates from the locking rod 800, thus not restricting the posture of the bearing platform 300, allowing the bearing platform 300 to tilt and rise freely without affecting the leveling accuracy. After leveling is completed, the locking mechanism 900 reliably locks the locking rod 800, making the bearing platform 300 and the support frame 200 form a rigid whole, with a fixed posture that does not wobble or shift, achieving high-precision leveling and high-rigidity locking.

[0141] After the locking end 910 of the locking mechanism 900 is locked with the locking rod 800, the bearing platform 300, the locking rod 800, the support frame 200, and the lifting assembly 410 form a closed rigid structure, significantly improving the overall rigidity. This prevents the platform from swaying, sinking, or tilting during subsequent electrolytic cell assembly, docking, maintenance, and collision disturbances, ensuring stability throughout the assembly process. Simultaneously, it reduces the long-term static load pressure on the lead screw 41111, push rod 412, and drive unit 411 in the lifting assembly 410, preventing fatigue, deformation, and self-locking failure of the lead screw 41111, and significantly extending the service life of the lifting assembly 410.

[0142] Specifically, the locking end 910 of the locking mechanism 900 can be configured as an arc-shaped notch structure, which is adapted to the outer wall surface of the locking rod 800. When it is necessary to lock the locking rod 800, the locking mechanism 900 drives the locking end 910 to abut against the locking rod 800, and applies a lateral force to the locking rod 800 through the locking end 910 to achieve the locking of the locking rod 800. Alternatively, the locking end 910 and the locking rod 800 can be locked by a snap-fit ​​engagement. In the embodiments of this application, no specific limitation is placed on the locking method of the locking end 910 and the locking rod 800.
