Description

Technical Field

[0001] This invention relates to communication tower reinforcement technology, specifically to a communication tower reinforcement structure, installation method, maintenance method, and control method. Background Technology

[0002] In the reinforcement engineering of communication towers, to improve their anti-tilting performance and adapt to the installation requirements of new base station equipment, a common approach is to arrange multiple prestressed tendons on the outer perimeter of the upper part of the tower. However, the installation and maintenance of prestressed tendons in existing technologies have significant shortcomings. Specifically, the construction phase requires complex step-by-step symmetrical tensioning operations. For example, when six prestressed tendons are evenly arranged around the tower, the first and fourth tendons must be tensioned first, followed by the second and fifth, and finally the third and sixth. This symmetrical tensioning process significantly increases on-site construction time costs. More importantly, during long-term service, if a prestressed tendon experiences prestress attenuation due to environmental stress or material aging, such as a decrease in the tension of the first prestressed tendon, it will directly weaken the radial support capacity in that direction. This local force imbalance will cause the resultant force center of all prestressed tendons to deviate from the geometric axis of the tower. Typically, when the tension of the prestressed tendon on the left weakens, the overall resultant force shifts to the right, thus exerting a continuous unilateral thrust on the tower. Over time, such unbalanced forces eventually induce the tower structure to tilt or even become unstable, seriously threatening the safe operation of communication facilities. Summary of the Invention

[0003] The purpose of this invention is to provide a reinforcement structure, installation method, maintenance method and control method for communication towers, which has the advantages of simplifying the installation and maintenance process, avoiding the risk of tower tilting caused by prestress imbalance, and improving structural stability and safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A communication tower reinforcement structure includes an upper connecting plate, a tie rod, a winding wheel, a tension sensor, a wind speed sensor, a controller, and a rotation mechanism. The upper connecting plate is fixedly connected to the outer periphery of the upper end of the tower. Multiple winding wheels are arranged around the circumference of the tower and are rotatably connected to the upper connecting plate; Multiple tie rods correspond one-to-one with multiple winding wheels, arranged around the circumference of the tower. The lower end of the tie rod is anchored in the ground, and the upper end of the tie rod is detachably connected to the winding wheel. Tension sensors are installed on the tie rods to detect tension; wind speed sensors are installed on the tower to detect ambient wind speed. The controller controls the rotating mechanism based on the tension, and the rotating mechanism can drive one to all winding wheels to rotate, which facilitates tension compensation and synchronous tensioning.

[0005] Furthermore, the rotating mechanism includes a self-locking reducer, a clutch, and a motor. Each take-up reel is equipped with a separate self-locking reducer and clutch. The motor transmits torque to the input end of each clutch, and the controller controls the engagement / disengagement state of each clutch to control the number of take-up reels driven by the rotating mechanism.

[0006] Furthermore, the tower body is basically a cylindrical structure, with an upper connecting plate installed on the outer periphery of the tower body. The rotating mechanism also includes a drive gear and a driven gear. The drive gear is a ring structure and is coaxially rotatably connected to the outside of the tower body. The motor is installed on the tower body and is connected to the drive gear for transmission. Multiple driven gears are provided, which are connected to the corresponding clutch input end and mesh on the outer periphery of the drive gear.

[0007] Furthermore, the self-locking reducer adopts a worm gear reducer.

[0008] Furthermore, the reinforcement structure also includes bearing bushes. Both the bearing bushes and the drive gear are separate structures. The bearing bushes are installed between the tower body and the drive gear. The lower end of the bearing bushes is provided with an outwardly extending flange, which supports the lower side of the drive gear, while the upper connecting plate supports the upper side of the drive gear.

[0009] Furthermore, the upper connecting plate is provided with mounting holes, the clutch is installed in the mounting holes, the self-locking reducer is installed on the upper side of the upper connecting plate, the input end of the self-locking reducer is connected to the output end of the clutch, and the driven gear is rotatably connected to the lower side of the upper connecting plate and connected to the input end of the clutch.

[0010] Furthermore, the reinforcement structure also includes a lower connecting plate, which is fixedly connected to the outer side of the middle of the tower. Multiple reversing wheels are installed on the lower connecting plate around the circumference of the tower. The tie rods extend vertically from the winding wheel to the corresponding reversing wheel and then tilt outward and anchor in the ground.

[0011] An installation method for installing the above-mentioned reinforcement structure, comprising the following steps: Step a: Install the upper connecting plate and its corresponding components on the upper end of the tower; Step b: One end of the multiple tie rods is anchored in the ground, and the other end is connected to the corresponding winding reel; Step c: In a windless environment, the rotating mechanism drives all take-up wheels to rotate synchronously until the tensioning tendons are tensioned to the preset value.

[0012] A maintenance method for replacing the tie rods of the above-mentioned reinforcement structure: when one of the tie rods needs to be replaced, the two winding wheels corresponding to the tie rod and the tie rod on the opposite side rotate synchronously to release the corresponding prestress and loosen the tie rod. After replacing the new tie rod, in a windless environment, the two winding wheels rotate synchronously to tension the tie rod to a preset value.

[0013] A control method employs the aforementioned reinforcement structure, where a tension sensor detects the tension of each tie rod in real time in a windless environment. When the tension of one tie rod decreases, the controller controls the corresponding winding wheel to rotate to compensate for the tension.

[0014] Through the above improvements, the reinforcement structure and method proposed in this application have the following beneficial effects: 1. It overcomes the problem of low efficiency due to multiple tensioning in existing reinforcement methods, thus improving construction efficiency; 2. It can avoid uneven prestress caused by fatigue of some tendons, thereby maintaining the continuity of the tower's stress balance, reducing the risk of tower tilting, and ensuring the stability of communication tower operation. 3. A worm gear reducer is used as a self-locking reducer in the rotating mechanism. The inherent self-locking characteristic of the worm gear reducer ensures that the winding wheel will not rotate in the opposite direction due to the tension of the tie rod when the motor stops working or there is an accidental power failure, thus reliably maintaining the preset tension of the tie rod. 4. By synchronously driving all winding wheels to rotate in a windless environment to achieve synchronous tensioning of the reinforcing bars, the tedious process of multiple symmetrical tensioning in existing technologies is avoided, significantly improving construction efficiency. 5. A method for replacing tie rods is proposed. By limiting the replacement operation to the synchronous adjustment of two tie rods on opposite sides, the problem of unbalanced force during the replacement process is fundamentally eliminated, and the structural risks caused by traditional single-rod replacement are effectively avoided. 6. A tension control method is proposed, which realizes automatic compensation for tension attenuation, ensures uniform distribution of prestress in all directions, avoids the generation of lateral resultant force, and thus effectively prevents the tower from tilting.

[0019] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] This application provides a reinforcement structure for communication towers. Existing methods for reinforcing communication towers require multiple tensioning operations when installing prestressed tendons, impacting construction efficiency. Furthermore, during subsequent use, fatigue may occur in some directions of the prestressed tendons, leading to a reduction in the radial component of the force in that direction. This, in turn, causes the prestressed tendons to exert a resultant force to the right on the tower, potentially causing it to tilt. This method is cumbersome to construct and makes it difficult to ensure uniform stress distribution and structural stability, posing safety hazards.

[0021] In this regard, such as Figures 1 to 4 This application proposes a reinforcement structure for a communication tower, including an upper connecting plate 3, tie rods 4, winding wheels 5, a tension sensor, a wind speed sensor, a controller, and a rotating mechanism. The upper connecting plate 3 is fixedly connected to the outer periphery of the upper end of the tower; multiple winding wheels 5 are arranged around the circumference of the tower and rotatably connected to the upper connecting plate 3; multiple tie rods 4 correspond one-to-one with multiple winding wheels 5, arranged around the circumference of the tower, with the lower end of the tie rod 4 anchored to the ground and the upper end of the tie rod 4 detachably connected to the winding wheel 5; the tension sensor is installed on the tie rod 4 to detect the tension; the wind speed sensor is installed on the tower to detect the ambient wind force; the controller controls the rotating mechanism according to the tension, and the rotating mechanism can drive one to all winding wheels 5 to rotate, facilitating tension compensation and synchronous tensioning.

[0022] Specifically, this embodiment provides a communication tower reinforcement structure, whose components include an upper connecting plate 3, a tie rod 4, a winding wheel 5, a tension sensor, a wind speed sensor, a controller, and a rotation mechanism. These components work together to achieve the function of reinforcing the communication tower.

[0023] The upper connecting plate 3 is designed to be fixedly connected to the outer perimeter of the upper end of the tower. This upper connecting plate 3 can be a clamp-type structure, fastened to the outer wall of the tower with bolts, or directly connected to the tower structure by welding. Its main function is to provide an installation base and support for other reinforcement components.

[0024] Multiple winding wheels 5 are arranged around the circumference of the tower and rotatably connected to the upper connecting plate 3. These winding wheels 5 can be evenly distributed around the tower. For example, bearing seats can be used to support the shafts of the winding wheels 5 on the upper connecting plate 3, allowing the winding wheels 5 to rotate freely.

[0025] Multiple tie rods 4 correspond one-to-one with multiple winding reels 5, arranged circumferentially around the tower. The lower end of each tie rod 4 is anchored to the ground, for example, by ground anchors or concrete foundations. The upper end of the tie rod 4 is detachably connected to the corresponding winding reel 5, for example, by pins, bolts or quick-connect fittings to fix the end of the tie rod 4 to the winding reel 5.

[0026] A tension sensor is mounted on the tie rod 4 to detect the tensile force borne by the tie rod 4. This tension sensor can be a strain gauge sensor or a piezoelectric sensor, which measures the tension of the tie rod 4 and outputs the measurement result.

[0027] A wind speed sensor is installed on the tower to detect ambient wind speed. This sensor can be mounted on the top or side of the tower to monitor the wind speed around the tower in real time and transmit the wind speed data to the controller.

[0028] The controller controls the rotation mechanism based on the detection results of the tension sensor. This controller can be a programmable logic controller (PLC) or a microprocessor, with preset control logic that makes judgments and decisions based on the received tension data.

[0029] The rotating mechanism is configured to drive one to all winding wheels 5 to rotate. This rotating mechanism controls the winding wheels 5 to achieve tension compensation and synchronous tensioning of the tie rods 4. For example, when insufficient tension is detected in a tie rod 4, the rotating mechanism can drive the corresponding winding wheel 5 to wind it up, thereby increasing the tension of the tie rod 4; when initial tensioning of all tie rods 4 is required, the rotating mechanism can synchronously drive all winding wheels 5 to ensure that each tie rod 4 is subjected to uniform force, thus reinforcing the tower.

[0030] The communication tower reinforcement structure of this application achieves accurate control and synchronous tensioning of the tension compensation of the tie rod 4 by introducing sensors to monitor the tension of the tie rod 4 and the ambient wind force in real time, and by automatically adjusting the rotating mechanism driven by the controller to drive the winding wheel 5. This overcomes the problem of low efficiency due to multiple tensioning in existing reinforcement methods and improves construction efficiency. At the same time, this structure can avoid uneven prestress caused by fatigue of some tie rods 4, thereby maintaining the continuity of the tower's stress balance, reducing the risk of tower tilting, and ensuring the stability of the communication tower operation.

[0031] As one implementation, this application further proposes that the rotating mechanism includes a self-locking reducer 6, a clutch 7, and a motor 8. Each take-up reel 5 is equipped with a separate self-locking reducer 6 and clutch 7. The motor transmits torque to the input end of each clutch 7, and the controller controls the engagement / disengagement state of each clutch 7 to control the number of take-up reels 5 driven by the rotating mechanism.

[0032] Specifically, the self-locking reducer 6 is a reduction device with a self-locking function, meaning that when its input end stops rotating, its output end cannot be reverse-driven. In this application, the self-locking reducer 6 ensures that the winding wheel 5 can stably maintain the tension after being adjusted to a preset tension, without the need for continuous application of braking force.

[0033] The clutch 7 is a device for connecting or disconnecting power transmission, enabling the engagement and disengagement of power transmission. For example, a friction clutch 7, an electromagnetic clutch 7, or a hydraulic clutch 7 can be used. In this application, the clutch 7 is used to selectively connect or disconnect the torque transmitted by the motor to a specific winding reel 5, thereby achieving independent control of a single or partial winding reel 5, rather than driving all winding reels 5 at once.

[0034] The appropriate type of motor can be selected, such as a DC motor, AC motor, stepper motor, or servo motor, based on the required torque, speed accuracy, and control method. As the power source for the entire rotating mechanism, the motor provides the necessary driving force for the rotation of the winding wheel 5 to achieve the tensioning or loosening of the tensioning tendon 4.

[0035] By equipping each take-up reel 5 with a separate self-locking reducer 6 and clutch 7, independent control of each take-up reel 5 is achieved. The motor serves as a common power source, transmitting torque to the input of all clutches 7 via a transmission mechanism, thereby reducing the number of motors and lowering system complexity and cost. The controller precisely controls the engagement or disengagement of each clutch 7 based on tension data detected by the tension sensor or a preset control strategy. In this way, the controller can flexibly select to drive one, some, or all of the take-up reels 5 to achieve precise tension compensation and synchronized tensioning.

[0036] Through the above technical solution, the rotating mechanism is refined into a structure consisting of a motor, a clutch 7, and a self-locking reducer 6, with each take-up reel 5 equipped with an independent self-locking reducer 6 and clutch 7. This configuration allows the controller to precisely control the engagement / disengagement state of each clutch 7, thereby selectively driving one or more take-up reels 5 to rotate. When tension compensation is required for a specific tie rod 4, the controller only needs to engage the clutch 7 of the corresponding take-up reel 5, and the motor can drive that take-up reel 5 for adjustment, while the tension of other tie rods 4 remains unaffected. Simultaneously, the application of the self-locking reducer 6 ensures that the take-up reel 5 can reliably maintain its position after adjustment, effectively maintaining the preset tension of the tie rod 4 and improving the stability and reliability of the reinforced structure.

[0037] As one implementation, this application further proposes a reinforcement structure for a communication tower, wherein the tower body is basically cylindrical, the upper connecting plate 3 is installed on the outer periphery of the tower body, and the rotating mechanism includes a drive gear 9 and a driven gear 10. The drive gear 9 is a ring structure, coaxially rotatably connected to the outside of the tower body, and the motor is installed on the tower body and is connected to the drive gear 9 for transmission. Multiple driven gears 10 are provided, connected to the input end of the corresponding clutch 7, and meshed on the outer periphery of the drive gear 9.

[0038] Specifically, the tower's body is designed to be essentially cylindrical, meaning its cross-section remains circular or nearly circular for most of its height. This structural form facilitates the installation of components on the outer perimeter of the tower.

[0039] The upper connecting plate 3 is fixedly installed on the outer circumferential surface of the tower body. This installation method ensures that the upper connecting plate 3 can stably support the winding wheel 5 and related components of the rotating mechanism installed on it, and keep it tightly connected to the tower body, thereby effectively transferring the tension of the tie rod 4 to the tower structure.

[0040] In addition to the motor, self-locking reducer 6, and clutch 7, the rotating mechanism further incorporates a drive gear 9 and a driven gear 10 as core components for torque transmission. These gears work together to form a mechanical transmission chain for distributing the motor's power to each winding reel 5.

[0041] The drive gear 9 is designed as a ring structure, with its central axis coinciding with the tower's axis of rotation, and is capable of rotating around this axis. This ring-shaped drive gear 9 is typically made of high-strength material and has teeth on its outer circumference for meshing with the driven gear 10. This coaxial ring design allows the drive gear 9 to act as a central power distributor, providing a unified power input to multiple driven gears 10 distributed circumferentially around the tower. The motor is securely mounted to the tower structure and mechanically connected to the ring-shaped drive gear 9 via a suitable transmission method (e.g., a pinion meshing with the ring-shaped drive gear 9).

[0042] The motor acts as a power source, and its output torque drives the ring drive gear 9 to rotate through this transmission connection. Multiple driven gears 10 are evenly or as needed distributed around the outer circumference of the ring drive gear 9 and mesh with the teeth of the drive gear 9. The output end of each driven gear 10 is mechanically connected to the input end of a corresponding clutch 7. When the drive gear 9 rotates, its torque is synchronously transmitted to all meshing driven gears 10 through gear meshing, and then to each clutch 7, realizing centralized drive of multiple clutches 7 by a single motor.

[0043] The above technical solution limits the application of this reinforcement structure to iron towers with cylindrical structures, facilitating the installation of the ring drive gear 9 and enabling a single motor to distribute torque to each clutch 7 by activating the drive gear and multiple driven gears 10. This design effectively solves the problem of how to efficiently, stably, and compactly transmit motor torque to each clutch 7 when multiple winding reels 5 are arranged around the circumference of the iron tower.

[0044] Meanwhile, because the drive gear 9 rotates coaxially with the tower body, the entire transmission system can better adapt to the geometry of the tower body, improving integration and stability. This scheme, combining centralized drive with distributed clutch 7 control, ensures that each winding wheel 5 receives stable and reliable power input when the tensioning rod 4 is synchronously tensioned or individually compensated, thereby improving the overall performance and reliability of the communication tower reinforcement structure.

[0045] As one implementation, this application further proposes that the aforementioned self-locking reducer 6 adopts a worm gear reducer. A worm gear reducer is a common mechanical transmission device, mainly composed of a worm and a worm wheel. When the worm rotates, its helical motion drives the worm wheel to rotate, thereby achieving speed reduction and torque transmission. Worm gear reducers have significant self-locking characteristics. In this application, the output end of the clutch 7 drives the take-up reel 5 to rotate via the worm and worm wheel.

[0046] Through the above technical solution, a worm gear reducer is used as the self-locking reducer 6 in the rotating mechanism. The inherent self-locking characteristic of the worm gear reducer ensures that when the motor stops working or there is an unexpected power outage, the winding wheel 5 will not rotate in the opposite direction due to the tension of the tie rod 4, thus reliably maintaining the preset tension of the tie rod 4. At the same time, its high transmission ratio characteristic allows the controller to perform more precise control over the rotation of the winding wheel 5, achieving accurate compensation and synchronous tensioning of the tie rod 4, further improving the stability and safety of the communication tower reinforcement structure.

[0047] As one implementation, this application further proposes a communication tower reinforcement structure, which also includes a bearing 11. The bearing 11 and the drive gear 9 are both split structures. The bearing 11 is installed between the tower body and the drive gear 9. The lower end of the bearing 11 is provided with an outwardly extending flange 12, which supports the lower side of the drive gear 9, and the upper connecting plate 3 supports the upper side of the drive gear 9.

[0048] Specifically, the bearing bush 11 is a sliding bearing whose main function is to provide stable support for the rotating drive gear 9 and effectively reduce friction and wear during its rotation. The bearing bush 11 is usually made of a material with good wear resistance and self-lubricating properties to meet the needs of long-term operation.

[0049] Both the bearing bush 11 and the drive gear 9 adopt a split structure, meaning they are not molded as a single piece but are composed of multiple detachable parts. This design greatly facilitates installation and dismantling operations on the exterior of existing iron towers, significantly reducing construction difficulty and maintenance costs.

[0050] The bearing bush 11 is installed between the tower body and the drive gear 9, serving as the interface between the two and ensuring that the drive gear 9 can rotate smoothly and coaxially around the tower body.

[0051] To further enhance the support stability of the drive gear 9, the lower end of the bearing bush 11 is specially provided with an outwardly extending flange 12. This flange 12 forms an annular support surface, which can directly support the lower side of the drive gear 9, effectively preventing the drive gear 9 from shifting downward or axially moving due to its own weight or transmission load. A thrust bearing can be installed between the flange 12 and the drive gear 9 to reduce the resistance of the drive gear 9. At the same time, the upper connecting plate 3, as a structure fixedly connected to the outer periphery of the upper end of the tower, also plays a crucial supporting role, supporting and limiting the upper side of the drive gear 9 from above. A thrust bearing can be installed between the upper connecting plate 3 and the drive gear 9 to reduce the resistance of the drive gear 9.

[0052] Through the above technical solution, the ring drive gear 9 can obtain stable and reliable support. The design of the split bearing bush 11 and drive gear 9 simplifies installation and maintenance, eliminating the need for large-scale modifications to existing towers. The low-friction support surface provided by the bearing bush 11, combined with the bidirectional limiting of the upper connecting plate 3 and the outer flange 12, ensures the smooth and efficient rotation of the drive gear 9.

[0053] As one implementation, this application further proposes the above-mentioned communication tower reinforcement structure, wherein the upper connecting plate 3 is provided with mounting holes, the clutch 7 is installed in the mounting holes, the self-locking reducer 6 is installed on the upper side of the upper connecting plate 3, the input end of the self-locking reducer 6 is connected to the output end of the clutch 7, and the driven gear 10 is rotatably connected to the lower side of the upper connecting plate 3 and connected to the input end of the clutch 7.

[0054] Specifically, the mounting holes on the upper connecting plate 3 serve to provide a positioning and mounting interface for the clutch 7, ensuring that the clutch 7 can be stably and accurately mounted on the upper connecting plate 3. The mounting holes can be designed according to the external dimensions and fixing method of the clutch 7. The clutch 7 is mounted in the mounting holes, meaning the clutch 7 body is embedded in or passes through the mounting holes of the upper connecting plate 3. This mounting method allows the clutch 7 to partially or completely pass through the upper connecting plate 3, with its housing or mounting flange tightly fitting the edge of the mounting hole, and can be fixed by bolts, welding, or other methods. This provides stable support for the clutch 7.

[0055] The self-locking reducer 6 is installed on the upper side of the upper connecting plate 3, that is, the self-locking reducer 6 is fixed in the upper area of ​​the upper connecting plate 3. Specifically, the self-locking reducer 6 can be directly fixed to the plane of the upper connecting plate 3 by bolts or other fasteners through its base or mounting flange.

[0056] The input end of the self-locking reducer 6 is connected to the output end of the clutch 7, aiming to establish a power transmission path from the clutch 7 to the self-locking reducer 6. Typically, this connection is achieved through mechanical fasteners such as couplings or splined shafts. The output shaft of the clutch 7 is aligned and connected to the input shaft of the self-locking reducer 6 to ensure that torque is efficiently and smoothly transmitted from the clutch 7 to the reducer.

[0057] Driven gear 10 is rotatably connected to the lower side of upper connecting plate 3, meaning that driven gear 10 can rotate freely around its axis and is located below upper connecting plate 3. Specifically, driven gear 10 can be mounted on the lower side of upper connecting plate 3 via bearing housing. This arrangement allows driven gear 10 to mesh with drive gear 9 and transmit power to clutch 7, while maintaining the compactness of the overall structure.

[0058] Driven gear 10 is connected to the input end of clutch 7, with the aim of transmitting the power received from driven gear 10 to the input end of clutch 7. Specific implementation methods may include keyed connection, splined connection, bolted connection, etc. The center hole of driven gear 10 mates with the input shaft of clutch 7 (or its connecting component) to ensure synchronous rotation, thereby effectively transmitting the torque from drive gear 9 to clutch 7.

[0059] Through the above technical solution, the clutch 7 is cleverly installed in the mounting hole of the upper connecting plate 3, so that the clutch 7 body is at least partially embedded in the upper connecting plate 3, improving the structural compactness. Meanwhile, the self-locking reducer 6 is arranged on the upper side of the upper connecting plate 3, and the driven gear 10 is rotatably connected to the lower side of the upper connecting plate 3, forming a layered and compact integrated installation layout. This layout allows the driven gear 10 to connect directly and efficiently to the input end of the clutch 7, while the output end of the clutch 7 is directly connected to the input end of the self-locking reducer 6, constructing a direct, efficient, and space-efficient power transmission chain.

[0060] As one implementation method, this application further proposes a communication tower reinforcement structure, which also includes a lower connecting plate 13 and reversing wheels 14. The lower connecting plate 13 is fixedly connected to the outer side of the middle part of the tower, and multiple reversing wheels 14 are installed on the lower connecting plate 13 around the circumference of the tower. The tie rod 4 extends vertically from the winding wheel 5 to the corresponding reversing wheel 14 and then tilts outward and anchors in the ground.

[0061] Specifically, the lower connecting plate 13 is a ring-shaped or segmented plate structure. Its main function is to provide a stable mounting base for the reversing wheel 14 and to serve as a support point for the path conversion of the tie rod 4. The lower connecting plate 13 is usually made of high-strength steel and is firmly fixed to the outer side of the middle of the tower by welding, bolting, or clamping to ensure that it can withstand the huge tensile force transmitted by the tie rod 4.

[0062] The reversing wheel 14 is a key component mounted on the lower connecting plate 13, and its function is to change the direction of travel of the tie rod 4. Each tie rod 4 corresponds to one reversing wheel 14, and these reversing wheels 14 are evenly arranged around the circumference of the tower and can rotate freely.

[0063] The path design of the tie rod 4 is the core of this scheme. The tie rod 4 first extends vertically downwards from the winding wheel 5 on the upper connecting plate 3, down the outer side of the tower body, until it reaches the lower connecting plate 13 fixed in the middle of the tower. Here, the tie rod 4 bypasses the corresponding reversing wheel 14. After passing the reversing wheel 14, the direction of the tie rod 4 changes; it is no longer vertically downwards, but tilts outwards, finally anchoring itself in a pre-set anchoring point on the ground. This path design allows the tie rod 4 to connect with the ground at a gentler, more optimized tilt angle after leaving the tower.

[0064] Through the above technical solution, the tie rod 4 is guided by the reversing wheel 14 in the middle of the tower, which also provides additional support and stability to the middle section of the tower, avoiding the problem of local stress concentration that may be caused by only reinforcing the top of the tower.

[0065] This application embodiment proposes an installation method for installing the above-mentioned reinforcement structure. The method includes the following steps: First, step a, the upper connecting plate 3 and its corresponding components are installed on the upper end of the iron tower; second, step b, one end of multiple tie rods 4 is anchored in the ground, and the other end is connected to the corresponding winding wheel 5; finally, step c, in a windless environment, the rotating mechanism drives all winding wheels 5 to rotate synchronously until the tie rods 4 are synchronously tensioned to a preset value.

[0066] In the specific implementation process, the installation of the upper connecting plate 3 must ensure that it is firmly fixed to the outer periphery of the upper end of the tower, providing a stable support base for the winding wheel 5, tension sensor, and rotating mechanism. The anchoring operation of the tie rod 4 requires that the lower end be reliably fixed in the ground foundation, while the upper end is reliably connected to the winding wheel 5 through a detachable connection method, which facilitates subsequent tensioning. The key lies in the execution of step c, which must strictly select a windless environment (within 3 minutes, with a maximum wind speed not exceeding 1m / s) to avoid wind interference with the accuracy of tension measurement. At this time, the controller rotates the mechanism synchronously to drive all winding wheels 5 according to the preset logic command, so that each tie rod 4 is evenly stressed under the same conditions. The tension sensor provides real-time feedback data until the design preset value is reached, thereby completing the overall tensioning in one go.

[0067] The core innovation of this embodiment lies in achieving synchronous tensioning of the tie rod 4 by simultaneously driving all the winding wheels 5 to rotate in a windless environment, thereby avoiding the tedious process of multiple symmetrical tensioning in the prior art and significantly improving construction efficiency.

[0068] The reinforcement structure of existing communication towers faces significant technical challenges during maintenance. When a tie rod 4 needs to be replaced due to fatigue, simply releasing the prestress of that tie rod 4 will reduce the radial component of the force in that direction, resulting in an unbalanced resultant force pointing to the opposite side on the tower. This unbalanced force may cause the tower to tilt, seriously threatening structural safety.

[0069] In this regard, the present application also discloses a maintenance method for replacing the tie rod 4 of the above-mentioned reinforcement structure. When it is necessary to replace one of the tie rods 4, the tie rod 4 and the two winding wheels 5 corresponding to the tie rod 4 on the opposite side rotate synchronously to release the corresponding prestress and loosen the tie rod 4. After replacing the new tie rod 4, in a windless environment, the two winding wheels 5 rotate synchronously to tension the tie rod 4 to a preset value.

[0070] In practice, the controller synchronously drives the tie rod 4 that needs to be replaced and the winding wheel 5 corresponding to the tie rod 4 on the opposite side, and synchronously unloads the prestress of the two tie rods 4. For example, if the tie rod 4 on the left side needs to be replaced, the prestress of the two tie rods 4 on the left and right sides will be unloaded symmetrically when unloading the prestress. Although the tie rod 4 on the right side does not need to be replaced, it is unloaded synchronously to prevent the tower from tilting due to uneven radial force caused by unloading the prestress on the left side alone. Remove the old tie rod 4 on the left side that needs to be replaced and install the new tie rod 4. The upper end of the new tie rod 4 is fixed to the winding wheel 5 by a detachable connector. Finally, in a windless environment, the controller drives the two winding wheels 5 on the left and right sides to rotate synchronously in the forward direction. Based on the feedback data from the tension sensor, the tension process is precisely controlled until the tension reaches the preset value. During the tensioning process, the tension of the two tie rods 4 remains balanced and basically equal. When the tension difference between the two tie rods 4 is large, the clutch 7 with the larger tension can be temporarily disengaged to reduce the tension difference, so that the tension of the two tie rods 4 remains basically equal during the tensioning process, thereby further improving the stability of the tower.

[0071] The core innovation of this embodiment lies in fundamentally eliminating the problem of force imbalance during the replacement of tie rods 4 by limiting the replacement operation to the synchronous adjustment of the two tie rods 4 on opposite sides. This design prevents the tower from unexpectedly tilting due to unloading on one side during the replacement of tie rods 4. Because the two tie rods 4 in symmetrical positions release or apply prestress simultaneously, the radial resultant force on the tower always remains in a balanced state, effectively avoiding the structural risks caused by traditional single-rod replacement.

[0072] In some of the embodiments described above in this application, a tension sensor is proposed to detect the tension of each tie rod 4 in a windless environment in real time. However, in the process of its implementation, if the tension of individual tie rods 4 decreases due to fatigue, it will disrupt the prestress balance and generate a lateral resultant force. Long-term action may cause the tower to tilt.

[0073] In response, this application further proposes a control method comprising the following steps: a tension sensor detects the tension of each tension rod 4 in real time in a windless environment; when the tension of one of the tension rods 4 decreases, the controller controls the corresponding winding wheel 5 to rotate to compensate for the tension.

[0074] The above technical solution achieves automatic compensation for tension attenuation, ensures uniform distribution of prestress in all directions, avoids the generation of lateral resultant force, and thus effectively prevents the tower from tilting.

[0075] Specifically, this method, based on real-time monitoring data from tension and wind speed sensors, periodically compares the tension of the tie rod 4 in a windless environment (maximum wind speed not exceeding 1 m / s within 3 minutes) to eliminate wind interference. When the tension of the tie rod 4 decreases by more than 5% compared to the preset tension value, the corresponding winding wheel 5 is driven to rotate and compensate, restoring the tie rod 4 to the preset tension value. Due to the closed-loop control mechanism, this process requires no manual intervention, significantly improving the self-adaptive capability of the prestressed system and fundamentally solving the structural imbalance problem caused by local fatigue.

[0076] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
