Description

Technical Field

[0001] This invention belongs to the field of engineering operation technology, and in particular relates to a method for rapid removal of high tower light poles near existing power lines. Background Technology

[0002] In infrastructure sectors such as railways, power, and municipal works, it is often necessary to maintain or dismantle tall towers (such as light poles, signal towers, and monitoring poles) adjacent to existing operating lines (such as electrified railways and high-voltage transmission lines). Currently, the industry commonly uses traditional segmented hoisting methods based on heavy lifting machinery for dismantling tall tower structures in such high-risk environments. The typical workflow of this method is as follows: First, using an aerial work platform or climbing technology, a lifting device is installed above the predetermined segment of the tower to be dismantled and connected to a crane; then, operators use equipment such as flame cutters, hydraulic shears, or large circular saws to make a one-time full-section cut around the tower, completely separating the segment to be dismantled from the substructure; finally, the crane lifts the separated tower segment to a safe area on the ground, and this process is repeated until the overall dismantling is completed. To ensure safety, temporary power outages or physical isolation measures are often required for nearby existing lines during operations. The work relies heavily on the skilled coordination and experience of on-site supervisors, machine operators, and cutting personnel. The timing of cutting and hoisting is coordinated through visual inspection, walkie-talkie communication, and other means, and the safe distance from existing lines is estimated.

[0003] Although the aforementioned existing technologies are widely used in practice, their systemic defects are clearly visible when considering the beneficial effects achieved by this invention. Firstly, regarding safety, existing methods immediately lose their lower support the moment the cutting is completed. There is an unavoidable window of human judgment and operational delay between the completion of the cutting and the effective load-bearing capacity of the crane. At this moment, the structure is in a free state, highly susceptible to sudden swaying due to factors such as wind loads, posing a significant risk of impacting nearby existing lines. Its safety control is essentially passive and delayed. Secondly, in terms of operational efficiency, a single full-section cut is time-consuming, involves numerous manual coordination steps, and has a slow response time, resulting in a lengthy overall operation time and excessive occupation of railway maintenance windows or line downtime, leading to high economic costs. Furthermore, existing methods lack intelligent adaptability; their process parameters are fixed and cannot be dynamically adjusted according to real-time wind conditions, structural corrosion, and other actual conditions. Faced with complex working conditions, they often have to adopt conservative plans or be forced to interrupt operations. In addition, the entire operation relies excessively on the subjective experience of personnel, resulting in poor controllability and repeatability, and large quality fluctuations. Finally, existing technologies fail to create sustainable and optimizable digital assets; each operation is an isolated event, hindering the continuous accumulation and systematic improvement of technical experience. Therefore, there is an urgent need for an innovative dismantling method that can fundamentally enhance security, efficiency, adaptability, and controllability. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method for rapid removal of high tower light poles near existing power lines, which solves the problems of delayed safety response, low efficiency, reliance on manual experience and inability to intelligently adapt to complex working conditions in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for quickly removing high-tower light poles near existing power lines includes the following steps: S1: Establish a digital twin model of the high tower light pole, and perform mechanical simulation based on the structural parameters, material properties and environmental loads of the tower pole to determine a segmented dismantling scheme that ensures structural stability during the segmented dismantling process. The segmented dismantling scheme includes the cutting position, pre-cutting depth and corresponding lifting force parameters of each dismantling segment. S2: For the tower section to be demolished, install a temporary load-bearing structure on its top and connect it to the lifting system; S3: Pre-cut the tower below the temporary load-bearing structure to form an annular cut with a depth of 60% to 90% of the current cross-sectional thickness; S4: Activate the lifting system to apply a pre-lifting force of 80% to 95% of the estimated weight of the segment being cut; S5: Complete the final cutting of the annular slit, and at the instant the cutting is completed, control the lifting system to synchronously execute the lifting action to lift the tower section away; S6: During the entire process of lifting the tower section, its spatial position and attitude are monitored in real time, and the lifting speed of each lifting point of the lifting system is dynamically adjusted to control its movement trajectory, so as to ensure that the spatial distance between it and the adjacent existing line is not less than a preset safety threshold. S7: Move the lifted tower section to a safe area, and repeat steps S2 to S6 for the remaining tower sections based on the segmented dismantling plan until dismantling is complete.

[0006] Preferably, in step S5, the lifting system initiates the lifting action within 100 milliseconds after receiving the signal that the final cutting is completed.

[0007] Preferably, in step S5, multiple cutting devices are evenly arranged and work together along the circumference of the annular cut, and the cutting progress of each cutting device is kept synchronized by a collaborative control system.

[0008] Preferably, in step S6, the preset safety threshold is determined based on the voltage level of the adjacent existing line, mechanical protection requirements, on-site wind speed, and the structural dimensions and weight of the current tower section.

[0009] Preferably, during the execution of steps S4 and S5, vibration and stress data of the tower are collected in real time, and the real-time collected data is compared with the simulation prediction data of the digital twin model corresponding to the current operation stage; when the data deviation exceeds the preset permissible range, the operation is automatically suspended.

[0010] Preferably, the real-time monitoring of the tower attitude in step S6 specifically involves monitoring its tilt angle and rotation angle; when the monitored values ​​exceed a preset stability threshold, dynamic correction is performed by adjusting the lifting speed of different lifting points of the lifting system.

[0011] Preferably, in step S3, the depth of the pre-cutting is adjusted in real time based on the actual wall thickness measurement of the tower at the cutting location and the surface corrosion condition.

[0012] Preferably, the method also includes an optimization step: dynamically optimizing the pre-cutting depth and pre-lifting force parameters of subsequent tower sections to be demolished based on the actual operation data of the demolished tower sections, and updating the segmented demolition scheme in the digital twin model.

[0013] Preferably, the adjacent existing line is an electrified railway contact network, and the preset safety threshold includes an electrical safety distance determined based on the voltage level and a mechanical safety distance determined based on the mechanical impact risk.

[0014] Preferably, the digital twin model is used to simulate and predict the stress concentration trend and deformation trend of key parts of the tower at the moment of completion of cutting and the initial stage of lifting. The trend prediction data serves as the benchmark for real-time control and safety judgment in steps S5 and S6.

[0015] The technical effects and advantages of the present invention regarding a method for rapid removal of high-tower light poles near existing power lines: 1. This invention, through the core combination of pre-cutting to preserve the cross-section and millisecond-level synchronous lifting, eliminates the dangerous stage of free fall or swinging after structural cutting in traditional processes from a physical perspective. Combined with real-time trajectory control and dynamic safety threshold monitoring, it achieves active, continuous, and closed-loop control of the tower section's movement trajectory, ensuring that its distance from adjacent existing lines (such as the overhead contact line of electrified railways) remains within an absolutely safe range, fundamentally solving the most critical safety management challenge in high-risk, near-line operations.

[0016] 2. This invention pre-cuts the main cutting work, resulting in extremely short final cutting time and seamless integration with the lifting action. The optimized solutions and parameters provided by the digital twin model avoid repeated trial and error on-site. Multi-device collaborative operation further accelerates cut formation. These synergistic technologies make the overall workflow compact and efficient, significantly reducing operations that traditionally take tens of hours to just a few hours, greatly minimizing time spent on nearby lines (such as railway maintenance windows), resulting in outstanding economic and social benefits.

[0017] 3. This invention is not a fixed procedure but possesses intelligent response and adjustment capabilities. In the face of sudden wind conditions, it can dynamically calculate and raise safety thresholds; in the face of localized corrosion or damage to the structure, it can adaptively adjust cutting parameters. The predictive function of the digital twin model provides forward-looking guidance for dealing with uncertainties. This strong adaptability enables the method to be safely implemented under various non-ideal working conditions, breaking through the limitations of traditional fixed processes.

[0018] 4. The entire demolition process of this invention is pre-simulated and verified using a digital twin model, monitored in real time by a sensor network, and precisely executed by an intelligent control system. This transforms traditional high-altitude operations, which rely on personal experience and hand-eye coordination, into a standardized and reproducible engineering process driven by data and models. This significantly reduces the risk of human error, improves the consistency and reliability of work results, and makes the quality of complex projects predictable and manageable.

[0019] 5. The digital twin model, operational parameters, and real-time monitoring data generated by this invention constitute valuable digital assets. Through machine learning, the system can continuously learn and optimize from historical operations, forming an optimal process library for different tower types and environments. This not only improves the level of individual operations but also enables the continuous accumulation and evolution of enterprise technological capabilities, giving the method long-term vitality and competitive advantage.

[0023] refer to Figure 1 This invention discloses a method for the rapid dismantling of high-tower light poles near existing power lines, aiming to solve the problems of high risk, low efficiency, and reliance on manual experience in existing technologies. The method first simulates the dismantling of the high-tower light pole by establishing a digital twin model, pre-determining a segmented dismantling plan including cutting positions, depths, and lifting force parameters. Then, a temporary load-bearing structure is installed on top of the section to be dismantled and connected to a lifting system for pre-cutting of the remaining section. Next, the lifting system is activated to apply a pre-lifting force, bringing the tower to a critical load-bearing state. The final cut is then completed, and the lifting system is controlled to synchronously execute the lifting action at the moment the cut is completed, hoisting the tower section away. Throughout the hoisting process, its trajectory is controlled in real time to ensure that the distance to the adjacent existing power line is not less than a dynamically calculated safety threshold. Finally, the tower section is transferred and the process is repeated until dismantling is complete. This invention achieves a fundamental improvement in the safety, efficiency, and intelligent adaptability of dismantling operations through the organic combination of digital twin simulation, pre-cut load-bearing conversion, millisecond-level synchronous lifting, and real-time trajectory monitoring.

[0024] Example 1

[0025] This embodiment provides a method for the rapid removal of high-tower light poles near existing railway lines, which is used in the standard removal process for high-tower light poles near electrified railways. The specific implementation includes: Objective: To fully demonstrate how the method of this invention, through systematic technical integration, can achieve safe, efficient, and controllable demolition operations in the typical and demanding scenario of "adjacent to existing lines".

[0026] Implementation conditions: The light pole to be removed is a 40-meter-high steel tapered pole, and the nearest horizontal distance between its top and the return line of the 27.5kV electrified railway contact network is 8 meters. The work must be completed within the "maintenance window" specified by the railway department.

[0027] Implementation steps: S1: Precise geometric point cloud data and actual wall thickness data of key components of the light pole are obtained using 3D laser scanning technology. Based on this, a finite element digital twin model is established in engineering simulation software. The entire process of lifting each segment is simulated to verify that its movement trajectory and spatial relationship with the adjacent contact wire always meet safety requirements. The simulation outputs the optimal segmentation scheme, dividing the light pole into 5 segments for dismantling. The cutting position of the first segment is determined to be 7.5 meters from the top of the pole, the pre-cutting depth is 75% of the measured wall thickness at that location, and the pre-lifting force is 85% of the calculated weight of that segment (1.2 tons).

[0028] S2: The operator uses an insulated aerial work platform to reach a position 0.5 meters above the cutting location. A high-strength closed steel clamp is installed here as a temporary load-bearing structure, and a shackle is used to reliably connect it to the main hook of an 80-ton truck crane.

[0029] S3: Operate the remote-controlled hydraulic circular saw mounted on the work platform to pre-cut around the lamp post. By precisely controlling the saw blade feed, a 9 mm deep circular cut is formed, retaining a 3 mm continuous metal cross-section.

[0030] S4: Start the crane and slowly raise the hook to tension the slings. Monitor the crane's load in real time. Stop lifting when the load reaches 1.02 tons. At this point, the tower's posture is stable, and the system enters the critical load-bearing state.

[0031] S5: The remote-controlled hydraulic saw quickly completes the final cut to the remaining 3mm thickness. A sensor mounted on the drive shaft sends a signal the instant the cut penetrates, and the system triggers the main winch lifting procedure within 95 milliseconds of receiving the signal.

[0032] S6: Throughout the entire process of lifting the tower section, the Beidou positioning module and inclinometer integrated on the clamp are used to transmit spatial pose data in real time at a frequency of 10Hz. The central controller compares this data with the electronic geofence of the overhead contact line, dynamically generates and executes anti-collision control commands.

[0033] S7: Move the first section of the pole that has been lifted to a safe area. Then, repeat steps S2 to S6 on the current top of the remaining poles until the entire pole is removed.

[0034] Results: The entire operation was safe and controllable, with the tower section's sway amplitude kept within 3 degrees and no intrusion into the railway safety clearance occurred. The total removal time for the entire tower was approximately 6 hours, more than doubling the efficiency compared to traditional methods.

[0035] Example 2

[0036] This embodiment provides a method for the rapid removal of high-tower light poles near existing power lines, which is used for the in-depth application of digital twin models. The specific implementation includes: Objective: To demonstrate the core role of digital twin models in demolition scheme development, process prediction, real-time monitoring, and dynamic optimization.

[0037] Implementation steps: S1: During the modeling phase, transient dynamic analysis is applied to the digital twin model. The simulation predicts the transient response of the structure due to elastic rebound at the moment the cutting is completed, as well as the stress concentration trend of key parts under wind load coupling during the initial lifting stage.

[0038] S3, S4, S5: During the corresponding stages of actual operation, vibration and stress data are collected in real time through a sensor network deployed on the tower.

[0039] Implementation Results: The real-time collected vibration frequency of 1.8Hz and peak stress were compared with the model's predicted values, and the deviations were all within the preset 10% safety allowable range. Based on the measured data from the first demolition section, the system automatically optimized the operating parameters for subsequent sections, fine-tuning the pre-lifting force of the second section from 85% to 88%, demonstrating the method's self-optimization capability.

[0040] Example 3

[0041] This embodiment provides a method for the rapid removal of high-tower light poles near existing power lines, used for multi-machine collaborative operation and rapid response control. Specific implementation details include: Objective: To verify the specific technical solution for large-sized tower sections, which involves the coordinated operation of multiple cutting devices and the achievement of millisecond-level synchronization between cutting and lifting.

[0042] Implementation steps: S3: For tower sections with a bottom diameter of 800 mm, three servo-controlled diamond wire saws are installed at 120-degree intervals on a circular work platform. A collaborative control system based on the EtherCAT bus is used to uniformly control the start, stop, and feed speed of the three wire saws, ensuring synchronized formation of the circular pre-cut.

[0043] S5: At the moment the final cut is completed, the encoder of the wire saw's main motor detects a sudden drop in load and generates a completion signal. This signal is transmitted to the programmable logic controller (PLC) via fiber optic cable. The PLC sends a command to the crane's proportional valve within a processing cycle of less than 20 milliseconds. The total delay time from signal generation to the crane starting to generate lifting force was measured to be 95 milliseconds.

[0044] Implementation Results: High-precision synchronous operation of multiple cutting devices was achieved, ensuring the flatness of the cut surface. An ultra-fast response time of less than 100 milliseconds between cutting completion and lifting start-up was achieved, eliminating the risk window period in traditional operations.

[0045] Example 4

[0046] This embodiment provides a method for the rapid removal of high-tower light poles near existing power lines, used for dynamic safety control and active correction. Specific implementation details include: Purpose of implementation: To demonstrate how the system dynamically adjusts safety strategies and automatically corrects deviations under sudden weather changes, ensuring safety under extreme operating conditions.

[0047] Implementation steps: S6: During the operation, the on-site wind speed sensor detected a sudden increase in wind speed to 8 m / s. The control system immediately initiated dynamic safety threshold calculation, obtaining a new dynamic safety threshold of 5.5 m / s. During the lifting process, the tilt sensor detected that the downwind tilt angle of the tower section increased to 3.5 degrees, exceeding the stability threshold of 3.0 degrees. The correction system was automatically triggered, generating a reverse correction torque by finely adjusting the lifting speed difference between different lifting points of the crane, stabilizing the tilt angle back to within 2.8 degrees within approximately 5 seconds.

[0048] Implementation Results: The system successfully responded to sudden gusts of wind, dynamically raising the safety control line and actively correcting attitude to suppress large swings of the pole sections. This ensured that the actual distance between the pole sections and the overhead contact line remained strictly within a safe range throughout the entire period of gusts.

[0049] Example 5 This embodiment provides a method for rapid removal of high-tower light poles near existing power lines, which is used for adaptive adjustment based on real-time detection. The specific implementation includes: Purpose of implementation: To demonstrate how the system adaptively adjusts key process parameters based on measured data when there are deviations between the actual condition of the tower and the design model.

[0050] Implementation steps: S3: Before dismantling the third section, a detailed inspection was conducted using an ultrasonic thickness gauge, revealing severe localized corrosion in this section, with a minimum remaining wall thickness of only 8 millimeters. The control system input this measured data into the algorithm, automatically generating a new instruction for the corroded area: the pre-cutting depth is dynamically adjusted to 75%.

[0051] Implementation results: Through adaptive adjustment based on real-time detection, shallower pre-cutting was performed in the rusted area, avoiding the safety hazard of accidental fracture due to localized low strength before final cutting.

[0052] Comparative Example 1 This comparative example provides a traditional sectional hoisting and dismantling method, including the following details: Purpose of implementation: By comparing with the present invention, the limitations of traditional methods and the technical advantages brought by the present invention are highlighted.

[0053] Implementation method: Using conventional technology, after setting up lifting points at the top of the tower, a full-section cut is performed using flame cutting. After the cut is complete, the ground commander notifies the crane operator via walkie-talkie to lift the tower. The distance between the tower section and the existing line is determined manually by visual inspection.

[0054] Implementation Process: In the removal of a 40-meter-high light pole near an electrified railway, full-section flame cutting took 15 minutes. After cutting, there was a delay of approximately 3 seconds between notification and the start of crane lifting, during which the pole section swayed more than 5 degrees due to wind. During the lifting process, due to a lack of precise monitoring and active control, the pole section swayed violently, with its end coming within 3 meters of the overhead contact line, forcing a temporary 10-minute power outage for the railway. The entire removal operation took a total of 15 hours.

[0055] Compared to Examples 1-5 and Comparative Example 1, the rapid dismantling method for high-tower light poles near existing power lines shown in Examples 1-5 of this invention represents a fundamental and systematic comparison of advantages and disadvantages with the traditional segmented hoisting dismantling method described in Comparative Example 1, in terms of technical concepts, implementation paths, and final results. The core difference lies in the fact that this invention, through a series of closed-loop, proactive, and intelligent technological integrations, transforms a high-risk, low-efficiency, and manual-dependent project into a predictable, high-precision, safe, and efficient project guaranteed by a technological system.

[0056] First, there is a fundamental difference in their safety control concepts. The traditional comparative method is essentially an open-loop, passive response model. Its safety relies on two vulnerable links: the operator's experience and visual observation, and the timeliness of human communication and coordination. This results in the structure being in an uncontrollable free state during the 3-second risk window between the completion of cutting and hoisting, ultimately leading to a dangerous situation with a swing amplitude exceeding 5 degrees and a distance of less than 3 meters. In contrast, this invention is based on a closed-loop, proactive prevention model. Through pre-cutting + critical load-bearing conversion technology, the structure is already under the load of the lifting system before the final cutting, eliminating the possibility of free fall and unstable swaying from a physical perspective. Simultaneously, digital twin simulation is used to pre-screen risks, millisecond-level synchronous control eliminates response delays, and real-time trajectory monitoring and dynamic geofencing replace manual visual inspection, constructing a multi-layered proactive safety protection system, achieving a leap from human-based to technology-based prevention.

[0057] Secondly, this invention achieves a significant improvement in operational efficiency and controllability. Traditional methods, due to lengthy full-section cutting (15 minutes), slow manual coordination, and frequent pauses caused by safety concerns, take up to 15 hours in total, and the process is uncontrollable, severely disrupting railway operations. This invention significantly shortens the cut formation time through multi-machine collaborative cutting technology. More importantly, its speed is reflected in systematic process optimization: pre-cutting reduces the final cutting to only tens of seconds; millisecond-level synchronization compresses the gaps between processes to almost zero; digital twins and adaptive optimization ensure that each operation is the optimal or near-optimal solution. Ultimately, under the premise of higher absolute safety standards, the total time is reduced to about 6 hours, efficiency is more than doubled, and the entire process is stable, continuous, and controllable.

[0058] Finally, this invention demonstrates a strong intelligent advantage in adapting to complex working conditions. Traditional methods use fixed process parameters, lacking the ability to adjust when faced with sudden gusts of wind or localized structural corrosion, leaving only rigid risks or complete shutdowns. This invention, however, functions like an intelligent system, possessing sensing, decision-making, and adjustment capabilities. Example 4 shows that it can sense wind speed changes in real time and dynamically calculate and adjust safety control thresholds; Example 5 shows that it can adaptively adjust the pre-cutting depth based on measured wall thickness and corrosion data. This dynamic decision-making and optimization capability based on real-time data allows the method to readily cope with on-site uncertainties, ensuring operational safety and feasibility under complex conditions—something traditional rigid processes cannot match.

[0059] In summary, Comparative Example 1 reflects the high-risk, low-efficiency, and heavily reliant-on-manual nature of traditional high-altitude near-field operations. In contrast, Embodiments 1-5 of this invention represent a completely new technological paradigm: it uses digital twins and intelligent sensing as its brain, pre-cutting load-bearing conversion and millisecond-level synchronous control as its precise reflexive nerves, and dynamic safety monitoring and adaptive adjustment as its immune system. Together, they constitute a complete technological entity capable of ensuring the safe, rapid, and reliable dismantling of high-tower light poles adjacent to lifeline projects such as railways. This is not merely an improvement in specific processes, but a systemic breakthrough in the evolution of engineering operation methods from mechanization and experience-based to digitalization and intelligence.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of protection of the claims.

[0061] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
