Description

Technical Field

[0001] This application relates to the field of cable-stayed bridge construction technology, and in particular to a cable-stayed bridge fastening and installation system and its control system. Background Technology

[0002] The cable-stayed bridge construction method is a key technology commonly used in cable-stayed bridge construction, especially suitable for cable-stayed bridges with long spans, high piers, or crossing complex terrain (such as canyons and rivers). The process begins with preparation, including defining the technical plan, setting up the site, and inspecting equipment and materials. Next, the main tower foundation and columns are constructed, and the cable-stayed bridge anchorage system is installed at the top of the tower. Then, the main beam segments are prefabricated and safely transported to the construction area. The core stage involves a cycle of "hoisting-clinging-tensioning," installing the main beam segment by segment from both sides of the main tower in reverse order. The cable-stayed bridge uses the weight transfer mechanism and the cable-stayed bridges work together to ensure segment stability, while simultaneously monitoring and adjusting deviations in real time. Once the cantilever section of the main beam reaches mid-span, the deviation of the closure section is adjusted, and shrinkage-compensating concrete is poured. After the strength reaches the required level, the cable-stayed bridge is gradually loosened to complete the system transition, forming a "tower-cable-beam" collaborative load-bearing structure.

[0003] Currently, the inclined cable-stayed method has significant drawbacks. To ensure construction safety, it requires substantial temporary measures, which necessitate a lengthy pre-construction preparation phase, undoubtedly extending the construction period. Furthermore, it involves high-altitude operations, posing significant risks. Therefore, improvements to the aforementioned technologies can shorten the preparation phase and reduce the time construction workers spend working at heights, thereby ensuring worker safety. Summary of the Invention

[0004] In order to improve the construction efficiency of cable-stayed bridges and reduce the risks of high-altitude operations for construction workers, this application provides a cable-stayed bridge fastening installation system and its control system.

[0005] On the one hand, the inclined cable-stayed installation system provided in this application adopts the following technical solution:

[0006] A cable-stayed mounting system and its control system include a base frame, horizontally mounted on both sides of the top of a tower column, with the base frame extending in opposite directions on both sides, and further comprising:

[0007] The sliding plate is horizontally set and slidably connected to the base frame. The sliding plates on the base frame on both sides of the top of the tower column slide in opposite directions.

[0008] The bridge deck is composed of multiple segmented beams, and inclined cables are installed on both sides of each segmented beam;

[0009] The main beam is vertically installed at the top of the tower column, in the middle of the two base frames. A bidirectional winding device is installed on the main beam, which connects to and winds the stay cables.

[0010] By adopting the above technical solutions, the construction process is simplified and construction efficiency is greatly improved. First, the sliding plate enables precise translation of the beam segments: the base frame is horizontally set on both sides of the top of the tower column, and the sliding plate is slidably connected to the base frame and can slide in opposite directions. The beam segments do not need to rely on large hoisting equipment to be lifted from the ground or water to the high-altitude cantilever end. The position adjustment of the beam segments can be completed simply by moving the sliding plate along the base frame, eliminating the complex process of coordinating the position of hoisting equipment and controlling the lifting posture. Second, the bidirectional winding device integrates the tensioning function: the bidirectional winding device on the main beam is directly connected to and simultaneously winds up the stay cables on both sides of the main beam. There is no need to set up additional special tensioning equipment (such as jacks and oil pumps) or manually calibrate the tensioning angle repeatedly. The automatic winding and unwinding of the stay cables is achieved through mechanical transmission, and the tensioning and fixing of the beam segments on both sides of the main beam is completed at the same time.

[0011] Furthermore, it also reduces the risks of high-altitude and dynamic operations, and improves construction safety. The segmented beam slides along the fixed base frame via a sliding plate, remaining in a "track-constrained" state throughout the process. It does not need to be suspended from the base frame for hoisting, completely avoiding the risks of swaying and falling of the segmented beam in traditional hoisting. At the same time, the sliding operation of the sliding plate can be remotely controlled from the ground, reducing the number of high-altitude operations and the duration of operation for construction personnel. The bidirectional winding device winds the cable at a uniform speed through mechanical transmission, which can precisely control the winding speed and tension increment of the cable, avoiding the stress concentration of the segmented beam caused by "sudden rise and fall of tension" in traditional manual tensioning. Moreover, the winding device is integrated on the fixed main beam, ensuring stable force distribution and eliminating the need to temporarily build a tensioning platform, further reducing the risk of structural instability during dynamic operations.

[0012] Finally, the above-mentioned technical solutions also improve the accuracy of beam installation and cable tensioning, ensuring the quality of bridge alignment. The sliding plate and the base frame adopt a guide rail sliding cooperation, and the sliding trajectory is strictly constrained by the base frame to avoid posture deviations during manual adjustment. The bidirectional winding device can collect the winding length and tension data of the cable in real time through torque sensors and displacement sensors, effectively avoiding stress concentration of the main beam or main tower deviation caused by uneven cable force, and reducing the cost of subsequent alignment correction.

[0013] Optionally, the bidirectional winding device is vertically slidably connected to the main beam.

[0014] By adopting the above technical solution, based on the "stayed cable installation system and its control system", a new design of "vertical sliding connection of a two-way winding device to the main beam" is added. This adapts to the tensioning angle of multi-segment stay cables and improves the rationality of tensioning force. When the stay cables are installed segment by segment from the tower column to the mid-span, the angle between the stay cables and the main beam increases with the position of the stay cable segment. A winding device with a fixed height is prone to causing lateral force during stay cable tensioning, resulting in lateral force concentration on the main beam and even causing the stay cable segment to shift. However, the two-way winding device can slide up and down along the main beam and adjust its height in real time according to the installation position of different stay cables. When installing stay cables close to the tower column, the winding device moves down to reduce the angle between the stay cables and the main beam, avoiding excessive lateral force. When installing stay cables far from the tower column, the winding device moves up to increase the angle, ensuring that the stay cable tension is mainly transmitted vertically and effectively dispersing the force on the main beam.

[0015] Furthermore, for the beam sections at different positions on both sides of the tower column, by adjusting the vertical height of the bidirectional winding device, the tensioning angle of the stay cables of the corresponding beam sections on both sides can meet the design requirements, thereby achieving "synchronous tensioning of beam sections with the same number on both sides". It is even possible to set 2-3 sets of sliding winding devices at different heights of the main beam (which need to be designed in conjunction with the load-bearing capacity of the main beam), corresponding to beam sections with different numbers, to achieve "parallel tensioning of multiple segments", which can further improve construction efficiency in specific construction environments.

[0016] Optional, also includes:

[0017] The winch device is horizontally slidably connected to both sides of the top surface of each of the base frames. Two winches on the same base frame are arranged opposite each other, and steel ropes are wound on the winches.

[0018] By adopting the above technical solution, the winch device is used to transport the sections of beam to be laid. During the hoisting process, the horizontal posture of the section can be adjusted in real time by synchronously controlling the winding and unwinding speeds of the steel ropes of the two winches, thus avoiding tilting. Even if slight tilting occurs due to factors such as airflow and equipment vibration during hoisting, it can be quickly corrected by finely adjusting the winding and unwinding length of the steel rope on one side. For sections of beam with different lengths, the distance between the two winches can be adjusted by horizontal sliding—the distance is reduced when hoisting short sections to connect the steel rope to the lifting point at the end of the section; the distance is increased when hoisting long sections to ensure that the lifting point is located in the safe stress zone of the section, preventing the ends of the section from sagging and deforming during hoisting. For sections of beam with different weights, there is no need to replace the main body of the winch device; only the appropriate specification of steel rope needs to be selected according to the weight.

[0019] The winch devices on both sides of the same base frame top surface are arranged opposite each other and can slide horizontally along the base frame. During operation, the two winch devices are connected to both sides of the beam section by steel cables. Before sliding the beam section, the horizontal position of the two winch devices is adjusted according to the preset sliding trajectory of the beam section, so that the direction of the steel cable tension is consistent with the sliding direction of the beam section. During the sliding process, by synchronously controlling the steel cable winding speed and tension of the two winch devices, the lateral deviation of the beam section can be corrected in real time. If the beam section deviates to one side, the winch device on the corresponding side slows down the winding speed, while the winch device on the other side speeds up the winding speed, and the beam section is pulled back to the preset trajectory through the tension difference. Compared with the sliding method that relies solely on the sliding plate, this design significantly reduces the axial deviation of the beam section during sliding, and also reduces the amount of adjustment work for the subsequent beam section connection.

[0020] More importantly, the above technical solution achieves integrated connection between beam hoisting and sliding. When the hoisting device hoists the beam, it can slide horizontally along the base frame to directly send the beam to the top of the slide plate without the need for a temporary platform for transfer. After the steel rope is lowered to make the beam land on the slide plate, the beam can be moved along the slide plate by the horizontal sliding of the hoisting device without removing the steel rope (such as fine-tuning the position of the beam on the slide plate), achieving a seamless connection of "hoisting-positioning-sliding".

[0021] On the other hand, the control system of the inclined fastening installation system provided in this application adopts the following technical solution:

[0022] A control system for a cable tie-down installation system, applied to the cable tie-down safety system, includes a central processing module, a data measurement module, and a specific control module;

[0023] The measurement data module collects the spatial position data of the bidirectional winding device, the winch device, and the slide plate in real time, monitors the tension values ​​of the steel ropes on the stay cable and the winch device in real time, and measures the pressure values ​​of the slide plate in real time. The measurement data module is connected to the central processing module and sends the collected data to the central processing module.

[0024] The central processing module receives and calculates the measurement values ​​from the measurement data module. The central processing module has pre-stored calculation and instruction files. Based on the numerical calculation results, it generates control instructions and sends them to the specific control module.

[0025] The specific control module receives control commands and controls the hoisting device, the bidirectional winding device, and the slide plate to slide and operate according to the commands.

[0026] By adopting the above technical solutions, this control system, through the collaborative architecture of "central processing module + data measurement module + specific control module", addresses the pain points of the above-mentioned inclined cable-stayed installation system under the traditional manual control mode, such as non-real-time parameter monitoring, low control accuracy, difficulty in multi-device coordination, and delayed risk warning, and achieves intelligent and precise management and control of the installation system.

[0027] The central processing module, pre-stored with calculation and instruction files, can automatically generate synchronous control instructions based on real-time parameters fed back from the data measurement module (such as the matching relationship between the hoisting device position, steel rope tension, and sliding plate pressure during beam hoisting). For example, when hoisting a beam section above the sliding plate, the central processing module calculates the matching value between the steel rope tension and the sliding plate's load-bearing capacity, and simultaneously sends a "slowly lower" instruction to the hoisting device and a "adjust sliding position" instruction to the sliding plate to ensure the beam section is smoothly lowered. The data measurement module monitors key parameters such as stay cable tension, steel rope tension, and sliding plate pressure in real time. The central processing module compares the real-time data with preset safety thresholds (such as the maximum allowable tension of the stay cables and the maximum load-bearing capacity of the sliding plate). If the parameters exceed the thresholds (such as the steel rope tension suddenly rising to 1.1 times the safety value), the central processing module immediately generates an "emergency stop" instruction, cutting off the power source of the hoisting device and the bidirectional winding device through the specific control module, and simultaneously issuing an audible and visual warning. If the parameters are close to the thresholds (such as the sliding plate pressure reaching 90% of the safety value), a "fine-tuning" instruction is generated. Instructions (such as reducing the lowering speed of the hoisting device) are given to proactively avoid risks.

[0028] Optionally, the measurement data module includes a tension measurement unit, a pressure measurement unit, and a tensile force measurement unit;

[0029] The tension measuring unit measures the tension of the stay cable and the steel rope on the winch device, and sends the measurement results to the central processing module.

[0030] The pressure measurement unit measures the pressure on the slide plate and sends the measurement results to the central processing module.

[0031] The tension measurement unit measures the tension value on the beam surface at the connection point between the corresponding section beam and the stay cable, and sends the measurement result to the central processing module.

[0032] By adopting the above technical solution, based on the "control system of the inclined cable-stayed installation system," the measurement data module is refined into "tension measurement unit + pressure measurement unit + tensile force measurement unit," and the specific measurement object of each unit is clearly defined. This further optimizes the accuracy and practicality of data acquisition, addressing issues such as insufficient measurement specificity, severe data interference, and unclear risk positioning that may have arisen from the integration of measurement module functions in the previous solution. The tension measurement unit is specifically adapted to the inclined cable and steel rope: Targeting the "axial tension" characteristics of the inclined cable and steel rope, a tension sensor (such as a strain gauge tension sensor) is used, directly connected in series or clamped to the cable / rope body, to accurately capture changes in axial tensile force, avoiding errors caused by measurement direction deviation. The pressure measurement unit is specifically adapted to the sliding plate: Targeting the "vertical bearing pressure" characteristics of the sliding plate, a pressure sensor (such as a piezoelectric pressure sensor) is used, embedded in the contact surface between the sliding plate and the base frame, to directly measure the vertical pressure when the beam section is lowered, avoiding pressure transmission loss caused by improper sensor installation position (such as side installation). The tensile force measurement unit is specifically adapted to the beam section... Cable connection points: In view of the "local tension concentration" characteristic of connection points, miniature tension sensors (such as fiber optic grating tension sensors) are used and attached to the weld or weak point of the connection point to accurately capture the local tension generated on the beam surface due to cable tensioning, avoiding the omission of local stress due to the measurement range being too large (such as measuring the tension of the entire beam section);

[0033] Meanwhile, each measurement unit uses a dedicated sensor and independent signal transmission line, and the power supply system is independent, so as to avoid the power supply stability of other units being affected by the power consumption fluctuation of one unit. At the same time, it ensures the independence and authenticity of each type of parameter data and avoids misjudgment by the central processing module due to data interference.

[0034] Optionally, the measurement data module further includes a height measurement unit and a position acquisition unit;

[0035] The height measurement unit measures the height of the bidirectional winding device and sends the measurement result to the central processing module.

[0036] The position acquisition unit measures the position of the slide plate and sends the measurement result to the central processing module.

[0037] By adopting the above technical solution, based on the "separate tension, pressure and tensile force units for measurement data modules", a "height measurement unit + position acquisition unit" is further added, and it is clarified that they correspond to the measurement functions of the height of the bidirectional winding device and the position of the slide plate, respectively. This improves the data acquisition dimensions and addresses the problems of equipment spatial attitude loss, multi-device collaborative misalignment, and construction accuracy bottleneck caused by the lack of spatial parameter measurement in the previous solution.

[0038] The height measurement unit uses a laser rangefinder or displacement sensor (such as a wire-type displacement sensor), directly mounted on the main beam or bidirectional winding device, to collect the vertical height data of the winch device in real time. The central processing module can compare the measured height with the theoretical height in real time according to the tensioning angle requirements of the stay cables (such as the preset angle corresponding to different positions of the beam segment). If there is a deviation (such as a deviation exceeding ±0.5mm), the hoisting device height is immediately adjusted through the specific control module to ensure that the stay cables are always tensioned at the designed angle. The position acquisition unit uses a magnetic scale or encoder (such as an optical encoder), mounted on the sliding contact surface between the base frame and the slide plate, to collect the horizontal position data of the slide plate along the base frame in real time (measurement resolution up to ±0.05mm), and generate a position-time curve which is transmitted to the central processing module. The central processing module can monitor the position change of the slide plate in real time according to the preset sliding trajectory of the beam segment (such as the target position coordinates of each beam segment). If a deviation occurs (such as a lateral deviation exceeding ±0.5mm), the hoisting device or slide plate drive mechanism is immediately instructed to correct it. For example, when the section beam shifts to one side, the position acquisition unit feeds back the shift data, the central processing module quickly calculates the adjustment amount, controls the corresponding side winch device to tighten the steel rope, and pulls the slide plate back to the preset trajectory.

[0039] The central processing module can simultaneously receive data from the height measurement unit (hoisting device height), the position acquisition unit (slide plate position), and the existing tension, pressure, and pull units, performing multi-dimensional collaborative calculations. For example, when a beam section is hoisted above the slide plate, the central processing module must simultaneously meet the following conditions: the slide plate position is at the target coordinates (feedback from the position acquisition unit), the hoisting device height matches the beam section lowering requirements (feedback from the height measurement unit), the steel rope tension matches the beam section weight (feedback from the tension measurement unit), and the slide plate pressure is within a safe range (feedback from the pressure measurement unit). Only after all conditions are met will the hoisting device be instructed to lower the beam section.

[0040] Optionally, an angle calibration module may also be included;

[0041] The angle calibration module measures the included angle between the stay cable and the segmented beam, and sends the measured values ​​to the central processing module.

[0042] By adopting the above technical solutions, the angle between the stay cable and the segment beam is directly and accurately measured, avoiding abnormal stress caused by indirect calculation errors. Using laser angle sensors or dual-axis tilt sensors installed near the connection point between the stay cable and the segment beam, the real-time angle between the two can be directly captured. The data is transmitted directly to the central processing module without conversion, ensuring that the stay cable always transmits loads at the designed angle, significantly improving the structural safety. The angle calibration module can directly adapt to the angle requirements of different stages: the central processing module only needs to preset the angle thresholds corresponding to each segment beam (e.g., 25°-28° for segment beam 1, 32°-35° for segment beam 10), and the angle calibration module can monitor in real time whether the current angle meets the requirements of that stage without modifying the measurement logic of other parameters. For example, when installing segment beam 5, if the measured angle is 30° (preset 29°-31°), it is considered qualified; if when installing segment beam 6 (preset 30°-32°), the measured angle is still 30°, it is considered qualified and no adjustment is needed. This "direct benchmarking of stage thresholds" model eliminates the need to modify the conversion formulas for different stages, significantly improving the efficiency of switching operating conditions.

[0043] Optionally, a wireless module may also be included;

[0044] The wireless module connects the central processing module, the data measurement module, and the specific control module, providing a data and command transmission and reception channel between the central processing module and the data measurement module, and a control and feedback channel between the central processing module and the specific control module.

[0045] By adopting the above technical solution, the wireless module uses WiFi, 4G / 5G or industrial wireless protocols (such as LoRa) to build a transmission channel, eliminating the need to lay physical cables: parameters such as the included angle, tension, and position of the data measurement module can be wirelessly uploaded to the central processing module in real time, and control commands from the central processing module can also be wirelessly sent to specific control modules; during construction, as the beam section extends or the equipment moves, it is only necessary to ensure the signal coverage of the wireless module (the range can be extended by adding repeaters), without adjusting the wiring;

[0046] The wireless module can act as a "data bridge," wirelessly uploading construction data from the central processing module (such as the angle changes of each beam section and tensioning parameters) to the cloud platform or BIM system. On the one hand, the cloud can perform big data analysis on historical data (such as comparing the angle control accuracy of different beam sections to optimize subsequent construction parameters). On the other hand, the BIM model can receive the wirelessly transmitted position and angle data in real time, dynamically update the main beam installation progress and structural posture, and achieve synchronous linkage between the "virtual model and physical construction."

[0050] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0051] This application discloses a diagonal fastening installation system. (Refer to...) Figure 1 A cable-stayed bridge hoisting system is disclosed for the hoisting and construction of cable-stayed bridges. It includes a main beam 2 mounted on a tower column 1. The main beam 2 is a rectangular frame structure, specifically a welded steel support. The main beam 2 is vertically positioned at the center of the top side wall of the tower column 1. A bidirectional winding device 14 is installed on the main beam 2, specifically a hydraulic winch (recommended model JM-50). The hydraulic winch is vertically slidably connected to the main beam 2. Another winch device 16 is fixedly mounted at the top of the main beam 2. The drum of this winch device 16 is connected to the main body of the hydraulic winch via a steel rope, enabling the hydraulic winch to slide vertically along the main beam 2. In this embodiment, the hydraulic winch has two drums, supporting bidirectional winding, and the winding speed is adjusted by a hydraulic valve.

[0052] Reference Figure 1 Two sets of guide rails extend horizontally from the top of the tower column 1 to form a base frame 11. A sliding plate 13 is slidably connected to the base frame 11. The surface of the sliding plate 13 is horizontal, and the two opposite sides are slidably connected to the base frame 11. A winch device 16 is installed on the base frame 11. Unlike a hydraulic winch, the winch device 16 on the base frame 11 is composed of an electric winch. An electric winch is installed on each side of the base frame 11. The main body of the two electric winches slides along the length of the base frame 11. Steel ropes are wound on the drums of the two electric winches. The section beam 12 is connected to the steel ropes and is hoisted to the top of the tower column 1. With the sliding of the sliding plate 13, the section beam 12 is transported to the sliding plate 13. Under the action of the sliding plate 13, the installed section beam 12 is aligned, thus forming the bridge deck.

[0053] Based on this, construction can be carried out on both sides of the same tower column 1 simultaneously. With the bidirectional pulling of the hydraulic winch, the load on both sides of the same tower column 1 can be ensured to be uniform.

[0054] The implementation principle of the inclined cable-stayed installation system in this application embodiment is: "modular load-bearing + precise transfer + dynamic tensioning + collaborative control". Through the structural adaptation and functional linkage of components such as the base frame 11, sliding plate 13, bidirectional winding device 14, and winch device 16, the entire process of the section beam 12 from hoisting and sliding to tensioning and fixing is controllable. At the same time, relying on mechanical balance design and automated feedback mechanism, the structural stability and accuracy are ensured during construction.

[0055] 1. The system takes “Tower column 1 - base frame 11 - sliding plate 13 - section beam 12” as the core load-bearing chain. Through layered design, it achieves uniform load transfer, avoids local stress concentration, and provides a stable foundation for subsequent operations.

[0056] 2. The system solves the problem of precise transfer of the segment beam 12 from the precast platform to the installation position by means of the coordinated action of the hoisting device 16 and the sliding plate 13, relying on the dual control of "synchronous lifting + trajectory constraint".

[0057] 3. Following the closed-loop logic of "angle adaptation - tension control - real-time feedback", the bidirectional winding device 14 achieves dynamic adjustment of the tension angle and tension of the cable 15 through the collaboration of the vertical sliding structure and the torque sensor.

[0058] On the other hand, embodiments of this application disclose a control system for a cable-stayed mounting system. (Refer to...) Figure 2 A control system for a slanted cable-stayed installation system includes a central processing module 3, a data measurement module 7, a specific control module 5, an angle calibration module 6, and a wireless module 4. The control system uses the central processing module 3 as its core, the data measurement module 7 as its sensing end, and the specific control module 5 as its execution end. These three components are connected via a combination of wired and wireless methods, forming a closed-loop control chain of "sensing-computation-execution." As shown in Figure 2 (control system architecture diagram), the data measurement module 7 collects parameters such as the position, tension, and pressure of the installation system and transmits them to the central processing module 3 via the wireless module 4 or wired cable. The central processing module 3 generates control commands based on pre-stored algorithms and parameter thresholds and sends them to the specific control module 5. The specific control module 5 drives the hoisting device 16, the sliding plate 13, and the bidirectional winding device 14, while simultaneously feeding back the execution status to the central processing module 3, achieving dynamic monitoring of the entire process.

[0059] The central processing module 3 uses an industrial-grade PLC (Programmable Logic Controller) as its control core, supporting multi-protocol communication. It can simultaneously process multiple digital and analog signals, meeting the needs of parallel data computation across multiple modules. It is equipped with a network port for connecting the wireless module 4 and the specific control module 5; and a bus interface for connecting the data measurement module 7.

[0060] The data measurement module 7 collects key parameters of the installation system through multiple types of sensors, including a height measurement unit 72, a position acquisition unit 74, a tension measurement unit 71, a pressure measurement unit 73, and a tensile force measurement unit 75. The position acquisition unit 74 includes an encoder mounted on the sliding base of the winch device 16 and an absolute encoder mounted on the shaft end of the drive motor of the slide plate 13. The tension measurement unit 71 includes tension sensors connected in series on the stay cable 15 and the steel rope of the winch device 16, providing feedback on the tension value through analog signals. The pressure measurement unit 73 includes multiple sets of pressure sensors embedded in the contact surface between the slide plate 13 and the base frame 11, evenly distributed at the four corners of the slide plate 13, used to monitor the pressure distribution during the lowering of the beam section 12. The analog signals output by the sensors are converted into standard 4-20mA signals through a signal isolator, then aggregated by the data acquisition card, and transmitted to the central processing module 3 via an RS485 interface.

[0061] The angle calibration module 6 uses a dual-axis tilt sensor, installed on a steel bracket at the connection point of the stay cable 15 and the segment beam 12, to measure the angle between the stay cable 15 and the segment beam 12 in real time and transmit the data to the central processing module 3. The central processing module 3 pre-stores angle thresholds for different segments. If the measured angle is lower than the lower threshold, it instructs the vertical sliding platform of the bidirectional winding device 14 to rise, increasing the angle; if it is higher than the upper threshold, it instructs the platform to descend until the angle meets the requirements. When the rate of change of the angle exceeds the preset threshold, the central processing module 3 immediately instructs the winch device 16 to tighten the steel rope and the bidirectional winding device 14 to lock the stay cable 15, preventing the segment beam 12 from swaying due to sudden changes in the angle.

[0062] The specific control module 5 employs a servo driver and a servo motor, receives pulse signals from the central processing module 3, controls the motor speed to regulate the steel rope winding speed, and is equipped with an electromagnetic brake. When the central processing module 3 sends a stop command, the brake is de-energized and engages to prevent the steel rope from reversing. In other embodiments of this application, the specific control module 5 also includes a hydraulic driver, which receives a 4-20mA analog signal from the central processing module 3, controls the output flow of the hydraulic pump, and thereby adjusts the speed of the hydraulic motor of the slide plate 13 to achieve stepless adjustment of the sliding speed of the slide plate 13.

[0063] The wireless module 4 adopts an industrial-grade LoRa wireless module 4, which supports the LoRaWAN protocol. Its transmission signal can penetrate the concrete and metal structure of the tower column 1, adapting to complex construction environments. The control commands generated by the central processing module 3 are sent to the specific control module 5 through the wireless module 4. After the specific control module 5 completes the action, it feeds back to the central processing module 3 through the original link, forming a communication closed loop.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
