Description

Technical Field

[0001] This invention relates to the field of wind power equipment installation technology, specifically to a smart assembly platform for wind power hybrid towers and its operation method. Background Technology

[0002] Hybrid tower structures have been widely used in wind power construction, mainly consisting of a lower precast concrete tower section and an upper steel tower section. Hybrid towers have advantages such as tall towers, strong load-bearing capacity, and good wind resistance, which can effectively improve wind turbine efficiency.

[0003] When assembling mixed tower sections on site, prefabricated semi-circular or quarter-circular segments must be precisely spliced ​​together on the ground to form a complete circular tower section. This process places stringent demands on the positioning accuracy of the tower sections, the safety of the assembly operation, and the construction efficiency. Currently, mixed tower assembly operations in China still employ traditional construction techniques, mainly relying on simple welding platforms or temporary steel structure assembly platforms. Leveling and alignment of the tower sections are completed manually using simple tools such as jacks, jacking rods, and hand-operated hoists. The center position, concentricity, roundness, and levelness of the tower sections are all judged by visual inspection.

[0004] Existing traditional construction techniques have many technical shortcomings, specifically: 1. High operational safety risks: There are no automatic guidance and limiting mechanisms during the segmentation and assembly of large precast concrete tower sections, which makes the tower sections prone to swaying and overturning, posing serious construction safety hazards; 2. Insufficient assembly precision: The lack of professional attitude monitoring and laser alignment devices makes manual visual alignment prone to errors. It is difficult to control the concentricity, roundness, levelness and verticality deviations of the tower sections, which affects the subsequent connection of steel tower sections and the overall operational stability of the wind turbine. 3. High dependence on manual labor and low construction efficiency: The leveling and alignment of the tower sections rely entirely on repeated adjustments based on manual experience, which not only consumes a lot of manpower and time, but also results in poor consistency of accuracy after adjustment. 4. Poor platform versatility and terrain adaptability: Traditional assembly platforms are fixed structures, making it difficult to adapt to tower sections of different diameters. In addition, the platform construction requires a flat ground, which requires a large area of ​​hardening of the construction site, making it unsuitable for construction needs in complex terrains such as mountains. 5. High construction costs and long construction period: Traditional platforms lack modular design and cannot be repeatedly disassembled and reused. Each construction point needs to be rebuilt, resulting in a long construction preparation period and a significant increase in material and labor costs.

[0005] Among existing patented technologies, the invention patent with publication number CN120667320A discloses a modular assembly platform and its construction method. Although the modular assembly platform can be repeatedly disassembled and reused, and is convenient for on-site construction, the patent solution is not useful and inconvenient for accurately splicing semi-circular or 1 / 4 circular segments into complete circular tower segments on the ground. Furthermore, it does not involve any intelligent monitoring, automatic control, or correction technology, and lacks a precise control mechanism for the attitude, roundness, and concentricity of mixed tower segments. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent assembly platform for wind power hybrid towers and its operation method, aiming to improve the problems existing in the current hybrid tower assembly process, such as insufficient safety assurance, low assembly efficiency, poor tower segment positioning accuracy, weak versatility and terrain adaptability, high dependence on manual labor, and high construction costs.

[0007] To achieve the above objectives, according to a first aspect of the present invention, the present invention provides a smart assembly platform for hybrid wind power towers, comprising: The inner annular platform is equipped with a platform lifting cylinder for supporting and leveling the inner annular platform; Multiple radial beams are distributed along the circumference of the inner annular platform and are detachably hinged to it. Each radial beam extends radially along the inner annular platform and is equipped with a radial beam lifting cylinder. The limit adjustment mechanism is set on the radial beam in a one-to-one correspondence, including drive rollers, inner adjustment limit components and outer adjustment limit components; The power system is connected to each lifting cylinder, drive roller, internal adjustment limit assembly, and external adjustment limit assembly; The intelligent monitoring and sensing system includes monitoring sensors, a level, and an intelligent control unit. The monitoring sensors are located at the center of the annular platform and are used to monitor the attitude, displacement, and center positioning data of the mixing tower section in real time, and transmit the monitoring signals to the intelligent control unit. The intelligent control unit is electrically connected to the power system, the monitoring sensors, and the level, and is configured to control the power system to drive each lifting cylinder and the limit adjustment mechanism to work together according to the monitoring signals, so as to realize the automatic leveling, positioning, and correction of the mixing tower section.

[0008] Furthermore, the power system, monitoring sensors, and intelligent control unit are all located on the inner ring platform. The monitoring sensors include laser rangefinders and are configured to project laser reference points or laser reference lines onto the mixing tower section for real-time monitoring of the horizontality, verticality, concentricity, and radial displacement of the mixing tower section, and transmit the monitoring signals to the intelligent control unit.

[0009] Furthermore, the leveling instrument includes a platform leveling instrument and radial beam leveling instruments. Four platform leveling instruments are evenly distributed along the circumference of the inner annular platform to monitor the levelness of the inner annular platform and transmit the monitoring signals to the intelligent control unit. The radial beam leveling instruments are correspondingly installed on each radial beam to monitor the levelness of each radial beam and transmit the monitoring signals to the intelligent control unit. The intelligent control unit controls the lifting cylinders of the platform and radial beams to raise and lower based on the monitoring signals from the platform leveling instrument and the radial beam leveling instrument, thereby achieving automatic leveling of the inner annular platform and each radial beam.

[0010] Furthermore, the length direction of the drive roller is along the length direction of the radial beam, the drive roller is horizontally rotatably disposed in the radial beam, and the upper end of the drive roller is higher than the upper end face of the radial beam; the drive roller is driven by any one of hydraulic drive, electric drive or pneumatic drive.

[0011] Furthermore, both the inner and outer adjustment limiting components are located on the same side of the drive roller. The inner adjustment limiting component includes an inner radial adjustment block and an inner horizontal cylinder, and the outer adjustment limiting component includes an outer radial adjustment block and an outer horizontal cylinder. The length directions of the inner and outer horizontal cylinders are the same as the length direction of the drive roller. The inner and outer radial adjustment blocks are connected to the piston rods of the inner and outer horizontal cylinders, respectively.

[0012] Furthermore, the outer end of the annular inner platform is provided with a plurality of platform connecting lugs for connecting each radial beam. The end of the radial beam that is connected to the annular inner platform is provided with a radial beam connecting lug. The platform connecting lug and the radial beam connecting lug are provided with hinge holes that can be aligned with each other. The platform connecting lug and the radial beam connecting lug are detachably hinged together by a pin, and the pin is located in the hinge hole.

[0013] Furthermore, the intelligent control unit is electrically connected to a wireless communication module and is connected to a remote control system via the wireless communication module. The remote control system includes a controller and a display. The controller is used to send automatic assembly instructions or manual operation instructions to the intelligent control unit. The intelligent control unit controls the power system to drive the lifting cylinders and limit adjustment mechanisms according to the received instructions. The display is used to show in real time the monitoring data collected by the monitoring sensors and level, the working status of each actuator and the assembly progress, and to issue an alarm signal when the monitoring data exceeds a preset threshold.

[0014] According to a second aspect of the present invention, the present invention provides an operation method for the above-mentioned intelligent assembly platform for hybrid wind power towers, comprising the following steps: S1. Platform foundation leveling: Leveling the inner ring platform and each radial beam connected to the inner ring platform; S2. Hoisting and multi-dimensional attitude adjustment of the first semi-circular section of the hybrid tower: S2-1, Pre-limit setting: Before the first semi-circular section of the mixing tower is hoisted and lowered, the intelligent control unit controls the inner horizontal cylinder and the outer horizontal cylinder to drive the inner radial adjustment block and the outer radial adjustment block to extend to the preset limit position according to the preset tower section specification parameters, forming a guide channel; S2-2, Drop Guidance: The first semi-circular section of the hybrid tower is hoisted and lowered. When it approaches the guide channel, the monitoring sensor monitors the attitude and position data of the first semi-circular section of the hybrid tower in real time. The intelligent control unit judges the relative position deviation between the tower section and the guide channel based on the monitoring data, and sends guidance instructions to the hoisting equipment through the wireless communication module or prompts the operator through the display to adjust the drop position of the tower section so that it is aligned with the guide channel. S2-3, Positioning and Acceptance: After the tower section is aligned with the guide channel, it continues to fall onto the radial beam, so that the first semi-circular section of the mixed tower is located on the drive roller; during the falling process, the inner radial adjustment block and the outer radial adjustment block guide and limit the tower section from the inner and outer sides to prevent it from deviating too much. S2-4. Fine-tuning and positioning: After the first semicircular section of the mixing tower is positioned, the monitoring sensors continue to monitor its horizontality, verticality, concentricity, and radial displacement data in real time. The intelligent control unit controls the radial beam lifting cylinder, drive roller, inner horizontal cylinder, and outer horizontal cylinder to work together to adjust the attitude and position of the first semicircular section of the mixing tower in multiple dimensions until all parameters reach the preset accuracy requirements, thus completing the precise positioning of the first semicircular section of the mixing tower. S3. Hoisting and multi-dimensional attitude adjustment of the second hybrid tower semi-circular section: S3-1, Dynamic Limit Setting: Before the second mixing tower semicircular section is hoisted and lowered, the intelligent control unit controls the corresponding inner horizontal cylinder and outer horizontal cylinder to drive the inner radial adjustment block and outer radial adjustment block to extend to the limit position corresponding to the first mixing tower semicircular section according to the positioning data of the first mixing tower semicircular section, forming a docking guide channel. S3-2, Drop Guidance: The second hybrid tower semicircular segment is hoisted and lowered. As it approaches the guide channel, the monitoring sensor monitors the attitude and position data of the second hybrid tower semicircular segment in real time and compares it with the positioning data of the first hybrid tower semicircular segment. Based on the comparison results, the intelligent control unit determines the relative positional deviation between the tower segment and the guide channel, and sends guidance instructions to the hoisting equipment through the wireless communication module or prompts the operator through the display to adjust the drop position of the tower segment so that it is aligned with the guide channel. S3-3, Positioning and Acceptance: After the tower section is aligned with the guide channel, it continues to fall onto the radial beam, so that the second mixed tower semicircular section is located on the drive roller; during the falling process, the inner radial adjustment block and the outer radial adjustment block guide and limit the tower section from the inner and outer sides, so that it gradually moves towards the position where it docks with the first mixed tower semicircular section. S3-4. Fine-tuning and alignment: After the second mixing tower semicircular section is positioned, the monitoring sensors continue to monitor its horizontality, verticality, concentricity, and radial displacement data in real time, and compare them with the positioning data of the first mixing tower semicircular section. The intelligent control unit controls the radial beam lifting cylinder, drive roller, inner horizontal cylinder, and outer horizontal cylinder to work together to adjust the attitude and position of the second mixing tower semicircular section in multiple dimensions until the monitoring data shows that the center point of the second mixing tower semicircular section coincides with that of the first mixing tower semicircular section and the horizontality is consistent, thus completing the precise alignment of the two semicircular sections. S4. Docking and Locking: The first and second semicircular sections of the mixing tower, which have been precisely aligned, are joined together and pre-tightened using high-strength bolts, and then finalized and tightened according to process requirements. After tightening, the intelligent control unit controls the inner and outer horizontal cylinders to drive the inner and outer radial adjustment blocks to retract and reset, releasing the limit device and completing the assembly of a single mixing tower section.

[0015] Furthermore, step S1 is specifically as follows: The inner ring platform is placed on the construction site, the power system is started, and the platform lifting cylinders are raised and lowered by the intelligent control unit. Combined with the monitoring signal of the platform level instrument, the inner ring platform is adjusted to be level. Then, each radial beam is hinged to the inner ring platform. The radial beam lifting cylinders are raised and lowered by the intelligent control unit. Combined with the monitoring signal of the radial beam level instrument, each radial beam is adjusted to be level, providing a stable horizontal working foundation for the subsequent tower section assembly.

[0016] Furthermore, in steps S2-4 and S3-4, the coordinated action of multi-dimensional attitude and position adjustment of the first and second hybrid tower semicircular segments includes: When the horizontal or vertical data fed back by the monitoring sensor exceeds the preset threshold, the intelligent control unit controls the associated radial beam lifting cylinder to lift and lower, correcting the tilt angle of the semi-circular section of the mixing tower so that its horizontal and vertical properties meet the preset requirements. When the concentricity or radial displacement data fed back by the monitoring sensor exceeds the preset threshold, the intelligent control unit controls the inner and outer horizontal cylinders to drive the inner and outer radial adjustment blocks to perform dynamic extension and retraction adjustment, and at the same time controls the drive roller to rotate, driving the semicircular section of the mixing tower to perform radial movement fine adjustment and circumferential micro-rotation adjustment, so that the semicircular section of the mixing tower moves closer to the theoretical center position. The above adjustment process is repeated until all parameters fed back by the monitoring sensors reach the preset accuracy requirements.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention designs an intelligent assembly platform for wind power hybrid towers, consisting of an inner ring platform, radial beams, a limit adjustment mechanism, a power system, and an intelligent monitoring and sensing system.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 This embodiment provides a smart assembly platform for hybrid wind power towers, such as... Figures 1-3 As shown, it includes an inner annular platform 2, eight radial beams 1, a power system 7, and an intelligent monitoring and sensing system. The bottom of the inner annular platform 2 is equipped with platform lifting cylinders 9 for supporting and leveling the inner annular platform 2. Each radial beam 1 is evenly distributed along the circumference of the inner annular platform 2 and is detachably hinged to the inner annular platform 2. After connection, each radial beam 1 extends radially along the inner annular platform 2. Each radial beam 1 is equipped with one or more radial beam lifting cylinders 15 for supporting and leveling the radial beam 1.

[0023] like Figures 1-3 As shown, the specific connection structure between the annular inner platform 2 and the radial beams 1 is as follows: The outer end of the annular inner platform 2 is provided with multiple platform connecting lugs 12 for connecting each radial beam 1. The end of each radial beam 1 that connects to the annular inner platform 2 is provided with a radial beam connecting lug 16. The platform connecting lugs 12 and the radial beam connecting lugs 16 are provided with hinge holes that can be aligned with each other. The platform connecting lugs 12 and the radial beam connecting lugs 16 are detachably hinged together by a pin 17, which is located in the hinge hole. The annular inner platform 2 and each radial beam 1 are modular structures, which can be disassembled for easy transportation and on-site assembly. Furthermore, due to the presence of platform lifting cylinders 9 and radial beam lifting cylinders 15, they have strong terrain adaptability.

[0024] like Figure 1 and Figure 3As shown, each radial beam 1 is also equipped with a set of limit adjustment mechanisms, which are key components for adjusting the position and attitude of the mixing tower section. The limit adjustment mechanism includes a drive roller 10, an inner adjustment limit component, and an outer adjustment limit component. The drive roller 10 is horizontally rotatably mounted in the mounting position of the radial beam 1. The length direction of the drive roller 10 is consistent with the length direction of the radial beam 1, and the upper end face of the drive roller 10 is higher than the upper end face of the radial beam 1, so that the mixing tower section can directly contact the drive roller 10 after positioning, reducing the frictional resistance when the mixing tower section moves. The drive roller 10 can be driven by any of the following methods: hydraulic drive, electric drive, or pneumatic drive. Both the inner and outer adjustment limit components are located on the same side of the drive roller 10. The inner adjustment limit component includes an inner radial adjustment block 6 and an inner horizontal cylinder 13, while the outer adjustment limit component includes an outer radial adjustment block 5 and an outer horizontal cylinder 11. The length directions of the inner horizontal cylinder 13 and the outer horizontal cylinder 11 are the same as the length direction of the drive roller 10. The inner radial adjustment block 6 is fixedly connected to the piston rod end of the inner horizontal cylinder 13, and the outer radial adjustment block 5 is fixedly connected to the piston rod end of the outer horizontal cylinder 11. By extending and retracting the inner horizontal cylinder 13 and the outer horizontal cylinder 11, the inner radial adjustment block 6 and the outer radial adjustment block 5 can be driven to complete the position adjustment, thereby achieving the limiting, guiding, and clamping of the mixing tower section.

[0025] like Figure 2 As shown, a power system 7, which is a hydraulic power system, is also installed on the annular inner platform 2. The power system 7 provides power to all the actuators of the entire platform. It is connected to the platform lifting cylinder 9, the radial beam lifting cylinder 15, the drive roller 10, the inner horizontal cylinder 13, and the outer horizontal cylinder 11. It can deliver appropriate power to each component according to control commands, ensuring the stable operation of each actuator. The intelligent monitoring and sensing system is responsible for data monitoring and command control during the assembly of the mixed tower section. It includes monitoring sensors 3, a level, and an intelligent control unit 8. To ensure the accuracy of monitoring and the convenience of control, the monitoring sensors 3 and the intelligent control unit 8 are integrated on the annular inner platform 2. The monitoring sensors 3 include a laser rangefinder sensor, which is installed at the center of the annular inner platform 2. It can project a laser reference point or laser reference line onto the mixed tower section to be assembled, thereby monitoring key data such as the horizontality, verticality, concentricity, and radial displacement of the mixed tower section in real time, and transmitting all collected monitoring signals to the intelligent control unit 8 in real time.

[0026] like Figure 2 and Figure 3As shown, the level instruments are divided into platform level instruments 4 and radial beam level instruments 14 according to their specific functions. There are four platform level instruments 4, which are evenly distributed along the circumference of the inner ring platform 2. They are specifically used to monitor the levelness of the inner ring platform 2. The radial beam level instruments 14 are set one-to-one with the radial radial beams 1. Each radial radial beam 1 is equipped with a radial beam level instrument 14 to monitor the levelness of the corresponding radial radial beam 1. The platform level instruments 4 and the radial beam level instruments 14 will synchronously transmit their respective monitoring signals to the intelligent control unit 8.

[0027] The intelligent control unit 8 is electrically connected to the power system 7, monitoring sensor 3, platform level 4, and radial beam level 14. It can receive signal data from all monitoring components and send control commands to the power system 7 according to the preset control logic to drive the lifting cylinders and limit adjustment mechanisms to work together. Specifically, for level adjustment, the intelligent control unit 8 can control the platform lifting cylinder 9 and the radial beam lifting cylinder 15 to complete the lifting action according to the monitoring signals of the platform level 4 and the radial beam level 14, thereby realizing the automatic leveling of the inner ring platform 2 and each radial radial beam 1, providing a horizontal and stable working foundation for the assembly of the mixed tower section.

[0028] In addition, the intelligent control unit 8 is electrically connected to a wireless communication module, which enables wireless communication between the intelligent control unit 8 and the remote control system and lifting equipment. The remote control system is equipped with a controller and a display. Operators can send automatic assembly commands or manual operation commands to the intelligent control unit 8 through the controller. After receiving the commands, the intelligent control unit 8 will control the power system 7 to drive each actuator to complete the corresponding actions. The display can show all monitoring data collected by the monitoring sensor 3, platform level 4, and radial beam level 14 in real time. It can also show the working status of each actuator and the assembly progress of the tower section. When the monitoring data exceeds the preset threshold range, the display will promptly issue an alarm signal to remind the operator to intervene in time, ensuring the safety and accuracy of the assembly operation.

[0029] Example 2 This embodiment provides an operation method for the wind power hybrid tower intelligent assembly platform provided in Embodiment 1, including the following steps: S1. Platform Foundation Leveling: This includes leveling the inner annular platform 2 and the radial beams 1 connected to it. Specifically: Place the inner annular platform 2 on the construction site, start the power system 7, and control the platform lifting cylinders 9 to raise and lower using the intelligent control unit 8. Combined with the monitoring signal from the platform level instrument 4, level the inner annular platform 2. Then, hinge the radial beams 1 to the inner annular platform 2, and control the radial beam lifting cylinders 15 to raise and lower using the intelligent control unit 8. Combined with the monitoring signal from the radial beam level instrument 14, level each radial beam 1, providing a stable horizontal foundation for subsequent tower section assembly.

[0030] S2. Hoisting and multi-dimensional attitude adjustment of the first semi-circular section of the hybrid tower: S2-1, Pre-limit setting: Before the first mixed tower semicircular section is hoisted and lowered, the intelligent control unit 8 sends a control command to the power system 7 according to the preset tower section specification parameters, drives the inner horizontal cylinder 13 and the outer horizontal cylinder 11 to extend, and drives the inner radial adjustment block 6 and the outer radial adjustment block 5 to move synchronously to the preset limit position. The two form a guide channel adapted to the first mixed tower semicircular section, providing guidance and limit basis for the tower section to fall. S2-2, Falling Guidance: The hoisting equipment is then started to lift the first semi-circular section of the hybrid tower and slowly lower it. When the tower section approaches the guide channel, the monitoring sensor 3 at the center of the inner ring platform 2 begins to monitor the attitude and position data of the first semi-circular section of the hybrid tower in real time and transmits the data to the intelligent control unit 8. The intelligent control unit 8 judges the relative position deviation between the tower section and the guide channel based on the monitoring data. If it is in automatic operation mode, the intelligent control unit 8 will send guidance instructions to the hoisting equipment through the wireless communication module to adjust the hoisting equipment's actions. If it is in manual operation mode, the deviation data will be displayed on the monitor, prompting the operator to manually adjust the falling position of the tower section until the tower section is precisely aligned with the guide channel. S2-3, Positioning and Acceptance: After the tower section is aligned with the guide channel, the hoisting equipment continues to control the tower section to fall onto the radial beam 1, so that the first semi-circular section of the mixed tower falls smoothly onto the drive roller 10. During the entire falling process, the inner radial adjustment block 6 and the outer radial adjustment block 5 always guide and limit the tower section from the inner and outer sides, effectively preventing the tower section from having excessive positional deviation and ensuring the stability of the position. S2-4. Fine-tuning Positioning: After the first semicircular section of the mixing tower is positioned, monitoring sensor 3 continues to monitor its horizontality, verticality, concentricity, and radial displacement data in real time. Based on the received monitoring data, intelligent control unit 8 controls the radial beam lifting cylinder 15, drive roller 10, inner horizontal cylinder 13, and outer horizontal cylinder 11 to work together to adjust the attitude and position of the first semicircular section of the mixing tower in multiple dimensions. This adjustment process is a closed-loop cyclic adjustment process. When the horizontality or verticality data fed back by monitoring sensor 3 exceeds a preset threshold, intelligent control unit 8 will control the associated radial beam lifting cylinder 15 to raise or lower, correcting the tilt angle of the semicircular section of the mixing tower. To ensure the horizontal and vertical alignment meets preset requirements, when the concentricity or radial displacement data fed back by monitoring sensor 3 exceeds a preset threshold, the intelligent control unit 8 controls the inner horizontal cylinder 13 and outer horizontal cylinder 11 to drive the inner radial adjustment block 6 and outer radial adjustment block 5 for dynamic extension and retraction adjustment. Simultaneously, it controls the drive roller 10 to rotate, causing the semi-circular section of the mixing tower to undergo radial movement fine-tuning and circumferential micro-rotation adjustment, bringing the semi-circular section closer to the theoretical center position. This adjustment action is repeated cyclically until all parameters fed back by monitoring sensor 3 meet the preset accuracy requirements. At this point, the precise positioning of the first semi-circular section of the mixing tower is completed. This section will serve as the reference section for subsequent docking. Figure 4 As shown.

[0031] S3. Hoisting and multi-dimensional attitude adjustment of the second hybrid tower semi-circular section: S3-1, Dynamic Limit Setting: The intelligent control unit 8 will retrieve the precise positioning data of the first mixing tower semicircular section, and control the extension and retraction of the inner horizontal cylinder 13 and the outer horizontal cylinder 11 at the corresponding positions according to the data, driving the inner radial adjustment block 6 and the outer radial adjustment block 5 to extend to the limit position corresponding to the first mixing tower semicircular section, forming a docking guide channel between the two, ensuring that the second mixing tower semicircular section can approach the docking position of the first mixing tower semicircular section; S3-2, Drop Guidance: Start the hoisting equipment to lift the second hybrid tower semicircular section and slowly lower it. When the tower section approaches the docking guide channel, the monitoring sensor 3 monitors the attitude and position data of the second hybrid tower semicircular section in real time. At the same time, the intelligent control unit 8 will compare the data with the positioning data of the first hybrid tower semicircular section in real time. Based on the comparison result, the relative position deviation between the tower section and the docking guide channel is determined. Similarly, the drop position of the tower section is adjusted by automatically sending guidance instructions or manually prompting, so that it is accurately aligned with the docking guide channel. S3-3, Positioning and Acceptance: After the tower section is aligned with the guide channel, it continues to fall onto the radial beam 1, so that the second mixed tower semicircular section is located on the drive roller 10; during the falling process, the inner radial adjustment block 6 and the outer radial adjustment block 5 guide and limit the tower section from the inner and outer sides, so that it gradually moves towards the position where it docks with the first mixed tower semicircular section. S3-4. Fine-tuning Alignment: After the second mixing tower semicircular section is positioned, monitoring sensor 3 continues to monitor its horizontality, verticality, concentricity, and radial displacement data in real time. Intelligent control unit 8 continuously compares this data with the positioning data of the first mixing tower semicircular section, and controls the radial beam lifting cylinder 15, drive roller 10, inner horizontal cylinder 13, and outer horizontal cylinder 11 to coordinate their actions, performing multi-dimensional attitude and position adjustments on the second mixing tower semicircular section. The adjustment logic is consistent with that of the first mixing tower semicircular section, forming a closed-loop cyclic adjustment, until monitoring data shows that the center points of the second and first mixing tower semicircular sections completely coincide and their horizontality remains consistent. At this point, the precise alignment of the two mixing tower semicircular sections is completed. Figure 5 As shown.

[0032] S4. Docking and Locking: The first and second semicircular sections of the mixing tower, which have been precisely aligned, are joined together and pre-tightened using high-strength bolts, and then tightened with final force according to process requirements. After tightening, the intelligent control unit 8 controls the inner horizontal cylinder 13 and the outer horizontal cylinder 11 to drive the inner radial adjustment block 6 and the outer radial adjustment block 5 to retract and reset, releasing the limit device. This completes the overall assembly of a single mixing tower section.

[0033] In summary, this invention designs an intelligent assembly platform for hybrid wind turbine towers, consisting of an inner ring platform 2, radial beams 1, a limit adjustment mechanism, a power system 7, and an intelligent monitoring and sensing system. It also develops corresponding refined operation methods to specifically address existing problems in hybrid tower assembly processes, such as insufficient safety assurance, low assembly efficiency, poor tower segment positioning accuracy, weak versatility and terrain adaptability, high reliance on manual labor, and high construction costs. This platform achieves automated guidance and limit positioning, intelligent attitude monitoring, and precise automatic leveling and correction during the ground assembly of the arc segment of the hybrid tower. Simultaneously, it considers the modular disassembly and reassembly of the platform, its reusability, and its adaptability to complex terrain. While improving the positioning accuracy of the entire circular assembly of the hybrid tower and ensuring construction safety, it significantly reduces reliance on manual labor, increases construction efficiency, and reduces construction preparation time and material and labor costs. This provides an efficient, accurate, safe, and economical technical solution for on-site assembly of hybrid wind turbine towers, ensuring the subsequent steel tower segment docking accuracy and the overall stability of the wind turbine operation.
