Description

[0002] Wind farms are usually located in areas with high wind speeds, such as coastal areas, mountainous areas, and plateaus. These areas have abundant wind energy resources, but also face complex meteorological conditions. Frequent changes in wind speed and direction are one of the main characteristics of these areas. The instability of wind speed will have a significant impact on the construction and operation of wind farms, especially during the hoisting process of the tower.

[0003] During the tower hoisting process of a wind farm, changes in wind speed can cause the tower to shake in the air, affecting its positioning accuracy and stability.

DETAILED DESCRIPTION

[0036] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0037] See also Figure 1-4 An embodiment of the present invention provides a tower section hoisting device, including a support frame 1, a hoist 2, a dynamic balancing fixture 3, and an anti-rotation device 4, wherein the support frame 1 is installed and fixed on the ground, the fixed end of the hoist 2 is installed and fixed on the support frame 1, the dynamic balancing fixture 3 is installed and fixed below the lifting end of the hoist 2, the anti-rotation device 4 is installed and fixed on the outside of the dynamic balancing fixture 3, and the tower crane section device 7 is installed and fixed through the dynamic balancing fixture 3.

[0038] In a possible implementation, the support frame 1 is the base part of the entire lifting equipment, which is usually fixed on the ground and bears the entire weight and external load of the lifting system. One end of the support frame 1 is connected to the fixed end of the hoist 2, and the hoist 2 is fixed on the support frame 1 to form a stable support foundation. The support frame 1 needs to be able to withstand the working load of the hoist 2, so it is usually made of steel structure or other high-strength materials. This connection ensures that the vertical lifting force of the hoist 2 can be transmitted to the ground through the support frame 1 to maintain the stability of the lifting equipment.

[0039] Furthermore, the lifting end of the hoist 2 is connected to the upper mounting portion 32 of the dynamic balancing fixture 3, forming a basic working unit for hoisting the tower section. The hoist 2 transmits the vertical lifting force to the dynamic balancing fixture 3 through a transmission system such as a rope or chain. The function of the dynamic balancing fixture 3 is to connect with the tower section device through three mounting ropes 6 to maintain the balance of the tower section. The angle of each mounting rope 6 is usually 120°, which ensures that the force in all directions is evenly distributed during the hoisting process of the tower section, preventing the tower section from tilting or becoming unstable.

[0040] Furthermore, an anti-rotation device 4 is installed on the outside of the dynamic balancing fixture 3, and the anti-rotation device 4 is composed of a windward plate 41, a rotating device 42, a moving device 43 and a control device. The function of the anti-rotation device 4 is to control the influence of wind and other external factors on the rotation of the tower section during the hoisting process, and to avoid unnecessary rotation of the tower section due to wind or other reasons during the hoisting process. The windward plate 41 of the anti-rotation device 4 can optimize the posture of the tower section under the action of wind by rotating and adjusting its position, and adjust the angle and orientation of the windward plate 41 in real time through the control system, so as to achieve the effect of balancing the influence of wind.

[0041] Furthermore, the tower section is fixed to the lower mounting portion 33 of the dynamic balancing fixture 3 by three mounting ropes 6. In order to ensure the stable hoisting of the tower section, the angle of the three mounting ropes 6 is maintained at 120° to ensure that the tower section does not tilt during the hoisting process. The damping balancing device 34 of the dynamic balancing fixture 3, especially the flywheel damper 342, can generate a reverse force by controlling the rotation speed of the flywheel when the tower section tilts, thereby effectively slowing down the tilting of the tower section and further ensuring the safety and stability during the hoisting process.

[0042] In the embodiment of the present invention, the dynamic balancing fixture 3 comprises a housing 31, an upper mounting portion 32, a lower mounting portion 33 and a damping balancing device 34, wherein the upper mounting portion 32 is mounted and fixed on the upper surface of the housing 31, the lower mounting portion 33 is mounted and fixed on the lower surface of the housing 31, and the damping balancing device 34 is mounted and fixed in the housing 31;

[0043] The upper mounting portion 32 is connected and fixed to the hoisting rope 5 of the hoist 2, and the lower mounting portion 33 is connected and fixed to the tower crane section device 7;

[0044] The upper mounting portion 32 is provided with at least one rope for connecting and fixing with the lifting rope 5 of the hoist 2, and the lower mounting portion 33 is provided with at least three mounting ropes 6 for connecting and fixing with the tower crane section device 7, and the angles between any adjacent ropes are equal, and the sum of the angles of all adjacent ropes is 360 degrees.

[0045] In a possible implementation, the structure of the dynamic balancing fixture 3 includes a housing 31, an upper mounting portion 32, a lower mounting portion 33, and a damping balancing device 34. The housing 31 serves as the load-bearing body of the entire device, receiving and transmitting the force from the hoist 2 and the tower section device. The upper mounting portion 32 is mounted on the upper part of the housing 31, and the lower mounting portion 33 is mounted on the lower part of the housing 31. The damping balancing device 34 is installed inside the housing 31, and balances and adjusts the dynamic changes of the tower section by mechanical or hydraulic means.

[0046] Furthermore, the upper surface of the upper mounting portion 32 is connected and fixed to the hoisting rope 5 of the hoist 2, bearing the vertical force transmitted from the hoist 2. The rope of the hoist 2 is connected to the dynamic balancing fixture 3 through the fixing point of the upper mounting portion 32, ensuring that the force transmission during the hoisting process is stable and vertical.

[0047] Furthermore, the lower mounting portion 33 is connected and fixed to the tower segment device, and its main function is to transfer the force from the dynamic balancing fixture 3 to the tower segment. In this connection, at least three ropes are arranged on the lower mounting portion 33, and they are respectively fixed to different connection points of the tower segment. The arrangement angles of the three ropes are designed to be equal, and the angles between each rope are equal, to ensure uniform distribution of force and prevent the tower segment from tilting or being unstable.

[0048] Furthermore, after the upper mounting portion 32 is connected and fixed to the rope of the hoist 2, the lower mounting portion 33 is fixedly connected to the tower section through at least three ropes. In order to ensure the stability of the hoisting process, the angles between all ropes are set to be equal and the sum is 360 degrees. Normally, the angle between the three ropes is 120 degrees, which ensures uniform distribution of force during the hoisting process and prevents any rope from being overloaded, causing the tower section to be unbalanced.

[0049] Furthermore, the damping balance device 34 is installed inside the housing 31, and the attitude of the tower section is adjusted in real time by adjusting the internal flywheel, hydraulic system or other damping elements. When the tower section tilts slightly or changes dynamically during the hoisting process, the damping balance device 34 can provide timely adjustment to reduce the risk of swaying or excessive tilting. Its function is to generate a reverse force by mechanical means to offset the unbalanced force, thereby maintaining the vertical stability of the tower section.

[0050] In the embodiment of the present invention, the damping balance device 34 includes a fixed frame 341, a drive controller and a flywheel damper 342. The fixed frame 341 is installed and fixed inside the housing 31, and the flywheel damper 342 is installed and fixed inside the fixed frame 341. The drive controller is electrically connected to the flywheel damper 342 to control the rotation speed of the flywheel damper 342.

[0051] The rotating shaft of the flywheel damper 342 is connected and fixed to the fixed frame 341 . When the fixed frame 341 is tilted by force, the rotating shaft of the flywheel damper 342 will generate a force to hinder the tilting and transmit it to the fixed frame 341 .

[0052] In a possible implementation, the fixed frame 341 is installed and fixed inside the housing 31 as the bearing base of the damping balance device 34. This connection ensures that the fixed frame 341 can stably bear the forces from the tower section and other components during the entire hoisting process. The fixed frame 341 is connected to the housing 31 by bolts, welding or other fixing structures to ensure that it will not loosen or shift during operation.

[0053] Furthermore, the flywheel damper 342 is connected to the fixed frame 341 through its rotating shaft. The flywheel damper 342 is usually composed of a heavy flywheel, which is connected to the inside of the fixed frame 341 through a bearing. When force or tilt is generated during the hoisting of the tower section, the rotating shaft of the flywheel damper 342 will rotate or change resistance accordingly with the movement of the fixed frame 341. The weight and rotation speed of the flywheel will generate a force that hinders the tilt, slowing down or offsetting the unbalanced movement of the tower section.

[0054] Furthermore, the drive controller is connected to the control system of the flywheel damper 342 through an electrical connection. The drive controller is responsible for adjusting the speed of the flywheel damper 342 to cope with different load conditions during the lifting process. The drive controller usually includes a sensor for detecting the tilt degree and dynamic changes of the fixed frame 341, and adjusting the speed of the flywheel according to real-time data, thereby providing the necessary resistance to offset the tilt.

[0055] Specifically, when the tower section begins to be hoisted and tilts, the fixed frame 341 is subjected to a force change, causing the rotation axis of the flywheel damper 342 to change accordingly. The drive controller receives the tilt data from the sensor and adjusts the rotation speed of the flywheel damper 342 in real time. The change in the rotation speed of the flywheel damper 342 causes the flywheel to generate corresponding resistance, and the inertia force of the flywheel offsets or slows down the tilt of the fixed frame 341, maintaining balance during the hoisting process. The design of the damping balance device 34 can accurately adjust the inclination of the tower section during the hoisting process through the effective connection between the fixed frame 341, the flywheel damper 342 and the drive controller, thereby significantly improving the safety, stability and efficiency of the hoisting operation.

[0056] In the embodiment of the present invention, the anti-rotation device 4 includes a windward plate 41, a rotating device 42, a moving device 43 and a control device, wherein the windward plate 41 is installed on the outer surface of the housing 31 through the rotating device 42 and the moving device 43, wherein the windward plate 41 is installed and fixed on the rotating part 422 of the rotating device 42, the fixed part 421 of the rotating device 42 is installed and fixed on the moving part of the moving device 43, the track of the moving device 43 is installed and fixed on the outer surface of the housing 31, and the control device is electrically connected to the rotating device 42 and the moving device 43 to control the rotating device 42 and the moving device 43;

[0057] The plane where the moving track of the moving device 43 is located is parallel to the cross section of the housing 31, and the moving track is circular;

[0058] The rotation axis of the rotating part 422 of the rotating device 42 is perpendicular to the plane where the moving track is located. There are at least two rotating devices 42, and the two rotating devices 42 are symmetrically arranged. There are also at least two moving devices 43, and their positions correspond to the rotating devices 42.

[0059] In a possible implementation, the windward plate 41 is a key component for preventing the tower section from rotating during the hoisting process, and is connected to the moving device 43 through the rotating device 42. The windward plate 41 is mounted and fixed on the rotating portion 422 of the rotating device 42. The rotating portion 422 is usually supported by a bearing and can rotate freely around the rotating axis. When the tower section is subjected to external force (such as wind force or other directional force), the windward plate 41 adjusts the angle through the rotating portion 422 to effectively prevent the tower section from rotating.

[0060] Furthermore, the fixed portion 421 of the rotating device 42 is mounted on the moving portion of the moving device 43. The fixed portion 421 of the rotating device 42 is usually connected to the moving portion of the moving device 43 by mechanical connection or welding, ensuring that the rotating device 42 can rotate freely or be fixed on the moving device 43. The track of the moving device 43 is fixed on the outer surface of the housing 31, so that the rotating device 42 can move along a circular track on the track.

[0061] Furthermore, the track of the moving device 43 is installed on the outer surface of the housing 31 and connected to the rotating device 42. The design of the moving device 43 allows it to move along a circular track on the track. The setting of the circular track ensures that the windward plate 41 can always maintain a suitable angle at any time to prevent the rotation of the tower section, especially when encountering external wind force or torque during the hoisting process.

[0062] Furthermore, the control device controls the rotating device 42 and the moving device 43 through electrical connection. The control device generally includes sensors and control systems for real-time monitoring of the position of the tower segment, the angle of the windward plate 41, and the tilt or rotation of the tower segment. The control device can automatically adjust the angle of the rotating device 42 and the position of the moving device 43 according to real-time data to ensure the effective operation of the anti-rotation device 4.

[0063] In the embodiment of the present invention, the moving device 43 includes an upper rail 431, a lower rail 432, an upper moving part 433, a lower moving part 434 and a driving motor 8, wherein the upper rail 431 is fixedly mounted on the upper side of the outer side of the shell 31, the lower rail 432 is fixedly mounted on the lower side of the outer side of the shell 31, the upper moving part 433 is mounted on the upper rail 431, the lower moving part 434 is mounted on the lower rail 432, and the driving motor 8 is connected and fixed to any one of the upper moving part 433 or the lower moving part 434;

[0064] The rotating device 42 includes a driving motor 8, a fixing part 421 and a rotating part 422, wherein the fixing part 421 is fixed on the upper moving part 433 and the lower moving part 434, the fixing part 421, the upper moving part 433 and the lower moving part 434 are on the same straight line, the rotating part 422 is installed in the fixing part 421, and the driving motor 8 is connected to the rotating part 422 to provide rotating power for the rotating part 422;

[0065] The control device is electrically connected to the drive motor 8 of the moving device 43 and the drive motor 8 of the rotating device 42 , respectively, and controls the operation parameters of the drive motor 8 .

[0066] In a possible implementation, the moving device 43 is composed of an upper rail 431, a lower rail 432, an upper moving part 433, a lower moving part 434 and a driving motor 8. The upper rail 431 and the lower rail 432 are respectively fixed on the outer side of the housing 31 to ensure the stability and load-bearing capacity of the rails. The upper rail 431 is installed on the upper side of the outer side of the housing 31, and the lower rail 432 is installed on the lower side to form a pair of parallel rails.

[0067] Specifically, the upper moving part 433 is installed on the upper track 431, and the lower moving part 434 is installed on the lower track 432. The two moving parts can slide along the track direction to carry the rotating part 422 of the rotating device 42. The connection between the upper moving part 433 and the lower moving part 434 is connected through the fixed part 421 to ensure the stability and bearing capacity of the entire structure. The drive motor 8 is fixed on the upper moving part 433 or the lower moving part 434, and provides power through a mechanical connection to move the moving part on the track. The power source of the drive motor 8 can be adjusted by an electrical signal to control the movement direction and speed of the moving part.

[0068] Furthermore, the rotating device 42 includes a driving motor 8, a fixed part 421 and a rotating part 422. The fixed part 421 is fixed at the connection point of the upper movable part 433 and the lower movable part 434, making it the core supporting component of the rotating device 42. The fixed part 421, the upper movable part 433 and the lower movable part 434 are on the same straight line to ensure the stability of the rotating device 42. The rotating part 422 is installed inside the fixed part 421 and is connected to the fixed part 421 through a rotating shaft. The driving motor 8 is connected to the rotating part 422 to provide rotational power so that the rotating part 422 can perform rotational motion, thereby driving the windward plate 41 and other components to make necessary angle adjustments during the hoisting process.

[0069] Furthermore, the control device is electrically connected to the drive motor 8 of the moving device 43 and the drive motor 8 of the rotating device 42, and monitors and controls the working state of the drive motor 8 in real time. The control device receives signals from the sensor and feeds back the position and angle information of the tower section and the windward plate 41. Based on these data, the control device accurately adjusts the motor, controls the motion parameters of the drive motor 8 of the upper moving part 433, the lower moving part 434 and the rotating device 42, and ensures the stable and efficient operation of the anti-rotation device 4 during the hoisting process.

[0071] The telescopic motor 411 is electrically connected to the control device, and the control device controls the telescopic amount of the telescopic motor 411 .

[0072] In a possible implementation, the fixed plate 413 is a hollow panel with strong structural support capability. The fixed end of the telescopic motor 411 is mounted on the fixed plate 413 to ensure that the telescopic motor 411 can stably perform telescopic motion. The fixed plate 413 fixes the telescopic motor 411 on its surface through a fastening device, so that the telescopic shaft of the telescopic motor 411 can be connected to the telescopic plate 412 and achieve precise telescopic control.

[0073] Furthermore, the telescopic plate 412 is installed in the fixed plate 413 and connected to the fixed plate 413 through a guide rail or a slide groove, etc., to ensure that the telescopic plate 412 moves along a fixed track when telescopic, and avoids deviation from a predetermined direction. When the telescopic motor 411 is started, the telescopic end of the telescopic motor 411 is fixed to one end of the telescopic plate 412 through a mechanical connection, thereby driving the telescopic plate 412 to extend or retract in the direction of the fixed plate 413. The design of the telescopic plate 412 is usually sliding, and can be flexibly retracted into the fixed plate 413, or extended from the fixed plate 413, so as to change the effective area of ​​the windward plate 41.

[0074] Furthermore, the telescopic motor 411 is connected to the control device through electrical signals, and the control device is responsible for accurately adjusting the telescopic amount of the telescopic motor 411. The control device determines the real-time position and state of the telescopic plate 412 by receiving feedback information from the sensor, and issues instructions as needed to control the movement of the telescopic motor 411. The electrical connection is carried out through a cable or a wireless transmission system to ensure that the control device can accurately control the operation of the telescopic motor 411 and realize the required adjustment of the telescopic plate 412 during the hoisting process.

[0075] In an embodiment of the present invention, the control device includes a wind direction measuring instrument, a wind speed measuring instrument, a gyroscope and a central processing unit, wherein the wind direction measuring instrument is used to measure the wind direction in real time, the wind speed measuring instrument is used to measure the wind speed in real time, and the gyroscope is used to measure the inclination and rotation angle of the dynamic balancing fixture 3 in real time. The central processing unit receives the driving feedback of the driving motor 8 from the measuring instrument, the wind speed measuring instrument, the gyroscope, and the rotating device 42 and the moving device 43, and generates control parameters for the driving motor 8 of the rotating device 42 and the moving device 43 in real time.

[0076] In a possible implementation, the wind direction measuring instrument is connected to the central processor via an electrical signal or a data line. The wind direction measuring instrument measures the wind direction around the tower hoisting equipment in real time and transmits the measurement result to the central processor. The central processor adjusts the angle and direction of the windward plate 41 according to the change of wind direction to ensure that the equipment can maximize the use or resistance of wind force during the hoisting process.

[0077] Furthermore, the anemometer is used to measure the wind speed in the current environment in real time, and is also connected to the central processor via an electrical signal or data cable. The change in wind speed directly affects the safety of the hoisting equipment. Therefore, the central processor dynamically adjusts the working state of the windward plate 41 and other related components according to the real-time change in wind speed. If the wind speed exceeds the safe range, the central processor can issue instructions to adjust the operating state of the equipment, or suspend the hoisting operation to ensure the safety of the operation.

[0078] Furthermore, the gyroscope is used to measure the dynamic balance of the hoisting equipment in real time and monitor the inclination and rotation angle of the hoisting equipment. Through the gyroscope, the central processor can grasp the posture changes of the equipment in real time to ensure that the equipment remains stable during the hoisting process and avoid equipment instability due to excessive tilt or rotation. The feedback signal of the gyroscope is connected to the central processor through the sensor, and the latter adjusts the various directions and positions of the equipment according to the real-time inclination data.

[0079] Furthermore, the central processor not only receives feedback information from various measuring instruments (wind direction measuring instrument, wind speed measuring instrument, gyroscope), but also receives driving feedback from the driving motor 8 in the rotating device 42 and the moving device 43 in real time. After the feedback signal of the driving motor 8 is transmitted to the central processor, the central processor combines environmental data (such as wind direction, wind speed, equipment inclination, etc.) to calculate and generate control parameters in real time. Through these control parameters, the central processor can accurately adjust the driving motor 8 in the rotating device 42 and the moving device 43, adjust the rotation angle, moving speed and stability of the tower section, and ensure the smooth progress of the hoisting operation.

[0080] Furthermore, the rotating device 42 and the moving device 43 cooperate with the lifting of the tower section. The central processor dynamically adjusts the drive motor 8 of the rotating device 42 and the moving device 43 according to the real-time measured data, and ensures that each step of the lifting process is accurate through the feedback control system. For example, when the wind speed and wind direction change, the central processor will command the rotating device 42 to fine-tune the direction of the lifting tower to avoid unstable operation caused by the influence of wind. At the same time, the dynamic balance data provided by the gyroscope ensures that the lifting equipment always maintains the appropriate angle and posture.

[0081] In an embodiment of the present invention, the control device further comprises a meteorological data receiver, which is used to receive real-time meteorological data from an external meteorological station and transmit the real-time meteorological data to a central processor so as to adjust the windward area of ​​the windward plate 41 in real time.

[0082] In one possible implementation, the meteorological data receiver transmits the received external meteorological data to the central processor via wireless signals, data lines or other communication protocols (such as Wi-Fi, Bluetooth, 4G / 5G networks, etc.). The meteorological data receiver can receive real-time weather data from external weather stations, including important parameters such as wind speed, wind direction, temperature, humidity, and air pressure. After receiving these data, the central processor can quickly compare and analyze real-time weather changes and make adjustments to the hoisting operation accordingly.

[0083] Furthermore, after receiving real-time meteorological data, the central processor will automatically adjust the windward area of ​​the windward plate 41 according to meteorological information such as wind speed and wind direction. Specifically, if the wind speed increases or the wind direction changes in real time, the central processor will calculate the optimal windward area and instruct the windward plate 41 to make corresponding adjustments. By changing the windward area of ​​the windward plate 41, the hoisting equipment can better cope with changes in external wind force and avoid unstable factors caused by too large or too small windward area.

[0084] Furthermore, the meteorological data receiver monitors the changes in the external environment in real time, and instructs the windward plate 41 and other parts of the hoisting equipment to make necessary adjustments through the central processor. These adjustments can ensure that the tower hoisting equipment is always in a stable state during the operation process, avoiding operational risks caused by weather factors. The central processor will determine whether it is necessary to stop the hoisting operation based on real-time meteorological data, especially when the wind speed is too high or the wind force changes greatly, and can immediately issue a pause command to ensure the safety of operators and equipment.

[0085] In an embodiment of the present invention, the hoisting equipment of the tower section also includes a remote control device, which includes a wireless communication device and a remote operation terminal. The wireless communication device is electrically connected to the central processor of the control device, and the remote operation terminal communicates with the central processor via the wireless communication device. The operator monitors and controls the operation of the hoisting equipment in real time via the remote operation terminal.

[0086] In one possible implementation, the remote control device is composed of a wireless communication device and a remote operation terminal. The wireless communication device is electrically connected to the central processor in the control system of the lifting equipment through a wireless signal (such as Wi-Fi, Bluetooth, 4G / 5G and other networks). The wireless communication device is responsible for converting the operating instructions of the remote operation terminal into signals that the central processor can understand, and returning the status information from the central processor to the remote operation terminal. The remote operation terminal interacts with the equipment in real time through this signal for remote monitoring and control.

[0087] Furthermore, the remote operation terminal is usually a portable device, such as a tablet computer, a smart phone or a dedicated control terminal, which integrates a monitoring interface and a control function. The operator can view the real-time operating status, equipment parameters, environmental data (such as wind speed, temperature, etc.) and other relevant information of the hoisting equipment through the remote operation terminal. In addition, the operator can send instructions through the terminal to control various functions of the hoisting equipment (such as starting, stopping, adjusting speed, adjusting the angle of the windward plate 41, etc.).

[0088] Furthermore, when the operator sends instructions through the remote operation terminal, the wireless communication device transmits these instructions to the central processor, and the central processor performs corresponding operations on the equipment according to the instructions. At the same time, the central processor will continuously monitor the working status of the equipment and feed back relevant data (such as equipment operating status, fault alarm, etc.) to the remote operation terminal to ensure that the operator can grasp the real-time status of the equipment in a timely manner.

[0089] In an embodiment of the present invention, the lifting equipment also includes a video monitoring device, which is installed on the support frame 1 and the hoist 2, and is used to monitor in real time the position of the tower section during the lifting process and the equipment status of the dynamic balancing fixture 3 and the anti-rotation device 4. The video monitoring device is electrically connected to the central processing unit to transmit the monitoring data to the central processing unit. The central processing unit generates a safety alarm signal in real time based on the monitoring data, and sends it to the operator through a wireless communication device.

[0090] In a possible implementation, the video monitoring device is installed on the support frame 1 and the hoist 2. These installation positions ensure that the key parts (such as the hoisting position, the dynamic balancing fixture 3, and the anti-rotation device 4) during the tower section hoisting process can be monitored in real time. The support frame 1 and the hoist 2 are important components of the hoisting equipment. Their status and operation are crucial to the safety during the hoisting process. Therefore, the video monitoring device is installed at these positions to fully monitor the hoisting process.

[0091] Furthermore, the video monitoring device is electrically connected to the central processor of the hoisting equipment through a data transmission interface (such as a wired or wireless signal) to ensure that the monitoring image can be transmitted to the central processor in real time. The central processor performs image processing based on the video signal, extracts key data during the hoisting process, and monitors the position of the tower section, the state of the balancing fixture, and the action of the anti-rotation device 4.

[0092] Furthermore, the video monitoring device captures images or video data during the hoisting process in real time and transmits the data to the central processor. The central processor determines whether the functions of the equipment are working normally based on the image data, and whether there are any potential dangers, such as deviation of the tower section, failure of the balancing fixture, or abnormality of the anti-rotation device 4. If any abnormality is detected, the central processor will generate a corresponding safety alarm signal.

[0093] Furthermore, the safety alarm signal generated by the central processor is sent to the operator's remote operation terminal (such as a tablet computer, mobile phone, etc.) through a wireless communication device. After receiving the alarm signal, the operator can respond immediately and take corresponding emergency measures to ensure the safety of the lifting operation.

[0094] Working process:

[0095] The working process of the tower section hoisting equipment includes several key steps, which mainly rely on the coordinated work of the support frame 1, the hoist 2, the dynamic balancing fixture 3, the anti-rotation device 4 and the control device. Specifically:

[0096] The support frame 1 of the hoisting equipment is first installed and fixed on the ground, and the support frame 1 provides a stable foundation for the entire hoisting process. The fixed end of the hoist 2 is installed on the support frame 1 to provide lifting power. The lower mounting portion 33 of the dynamic balancing fixture 3 is connected and fixed to the tower section device to form a hoisting point to ensure that the tower section will not be offset during the hoisting process. Further, the hoist 2 starts to run, and the lifting rope 5 is connected to the upper part of the dynamic balancing fixture 3 through the upper mounting portion 32 to start lifting the tower section device. The force during the lifting process is transmitted to the tower section device through the dynamic balancing fixture 3 to maintain its balance. The damping balance device 34 in the dynamic balancing fixture 3 plays a role, and through the control of the flywheel damper 342, the instability or tilting of the tower section device during the hoisting process is reduced or avoided. The rotating shaft of the flywheel damper 342 is connected to the fixed frame 341, which can provide anti-tilting force, thereby stabilizing the hoisting state of the tower section.

[0097] Furthermore, the windward plate 41 in the anti-rotation device 4 is installed on the outer surface of the housing 31 through the rotating device 42 and the moving device 43 to prevent the tower section from rotating or rotating uncontrollably during the hoisting process. The windward plate 41 automatically adjusts its angle according to the change of wind direction to resist the influence of wind force on the tower section. The moving device 43 controls the moving track and angle of the windward plate 41 to make it counteract the wind force direction and reduce the possibility of rotation. The rotating device 42 controls the rotation of the windward plate 41 to ensure that the tower section device is prevented from rotating due to external interference (such as wind force).

[0098] Furthermore, the control device includes a plurality of measuring instruments (such as an anemometer, an anemometer, a gyroscope, etc.) and a central processing unit. The wind speed and wind direction data are collected in real time by the anemometer, and the gyroscope monitors the inclination and rotation angle of the dynamic balancing fixture 3 in real time. The central processing unit dynamically adjusts the control parameters of the rotating device 42 and the moving device 43 according to these data. The control device receives real-time meteorological data from an external meteorological station through a meteorological data receiver, and adjusts the windward area of ​​the windward plate 41 to minimize the impact of wind force. This adjustment is automatic to ensure that the device can still work stably under different weather conditions.

[0099] Furthermore, the operator can monitor and control the hoisting equipment through the remote operation terminal. Through the wireless communication device, the remote operation terminal communicates with the central processor, allowing the operator to monitor the operating status of the equipment in real time and make necessary adjustments. The hoisting equipment is also equipped with a video monitoring device for real-time monitoring of the tower segment position and the working status of the dynamic balancing fixture 3 and the anti-rotation device 4. The video monitoring data is analyzed by the central processor, and a safety alarm is issued when a problem is found, so that the operator can respond in time.

[0100] Furthermore, when the tower section device is safely hoisted to the predetermined position, the hoisting machine 2 stops working and the hoisting process ends. The dynamic balancing fixture 3 continues to maintain the stability of the tower section, and the anti-rotation device 4 ensures that the device will not rotate after the hoisting is completed. After the hoisting is completed, all sensor data and monitoring information are fed back to the central processor for final evaluation. Data such as equipment status, performance of the hoisting process, and possible problems will be recorded for subsequent maintenance and improvement.
