Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically referring to an intelligent monitoring system for the climbing of a tower-building machine for the main tower of a cable-stayed bridge. Background Technology

[0002] In modern bridge construction, cable-stayed bridges have become an important choice for long-span transportation infrastructure due to their advantages such as strong span capacity and reasonable structural stress distribution. As the core load-bearing structure, the main tower of a cable-stayed bridge is often characterized by its large height, long construction period, and high technical requirements. Traditional construction equipment and monitoring methods can no longer meet the stringent requirements of efficiency, accuracy, and safety in contemporary engineering. Therefore, intelligent monitoring systems for the climbing of tower construction machines in cable-stayed bridge main towers have emerged.

[0003] As bridge construction moves towards longer spans and higher piers and towers, the height of the main tower is constantly being increased. Tower-building machines, as key equipment, must carry formwork, construction personnel, and materials through multiple climbing operations. The stability and safety of their climbing process directly determine the construction quality of the main tower. Traditional tower-building machine climbing relies heavily on manual monitoring, which suffers from problems such as delayed response and large data errors. Asynchronous climbing can easily lead to structural deformation, or abnormal pressure can cause equipment jamming, even resulting in safety accidents. Therefore, they are ill-suited to the high-precision requirements of high-pier and tower construction.

[0004] Meanwhile, the industry's demand for construction efficiency and cost control is increasing. In traditional hydraulic climbing formwork construction, each climb is time-consuming and requires a large amount of manual monitoring and adjustment, which not only extends the construction cycle but also increases labor costs and management difficulty. In large-scale projects such as the Guangzhongjiang Grand Bridge, every day the construction cycle is shortened can significantly reduce expenditures such as equipment rental and personnel salaries. This requires tower crane monitoring systems to have automated and efficient capabilities, and to reduce climbing time and improve construction efficiency through intelligent control.

[0005] Furthermore, modern engineering construction increasingly emphasizes end-to-end quality traceability and risk early warning. Traditional monitoring methods lack real-time data acquisition and analysis capabilities, making it impossible to dynamically track key indicators such as hydraulic parameters and displacement deviations during the tower crane's climbing process. Once a problem occurs, it is difficult to quickly locate the cause and take corrective measures, which may lead to quality defects or safety hazards. Summary of the Invention

[0006] In response to the above situation and to overcome the shortcomings of the existing technology, the present invention provides an intelligent monitoring system for the climbing of a tower-building machine for cable-stayed bridge main towers. This system effectively solves the problem that the current market cannot dynamically track key indicators during the climbing process of the tower-building machine, which leads to quality defects or safety hazards.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes an intelligent monitoring system for the climbing of a tower building machine for a cable-stayed bridge, including step one: parameter acquisition: during the climbing process of the tower building machine, climbing parameters are acquired in real time through the sensing layer of the monitoring system;

[0008] Step 2: Data transmission and analysis: The collected parameters are transmitted to the control layer, which analyzes and processes the data, compares the extension and retraction speeds and displacements of multiple sets of hydraulic cylinders in real time, and determines the state of the hydraulic system.

[0009] Step 3: Instruction Issuance and Feedback: Based on the instructions from the control layer, the hydraulic system is adjusted accordingly through the execution layer to control the climbing of the tower crane.

[0010] Furthermore, in step one, the sensing layer includes a hydraulic pump pressure sensor, a cylinder extension / retraction sensor, an oil flow sensor, an oil temperature sensor, a displacement sensor, and a wind speed sensor, etc.

[0011] The hydraulic pump pressure sensor collects the hydraulic pump pressure.

[0012] The cylinder extension / retraction sensor collects the cylinder extension / retraction amount;

[0013] The oil flow sensor collects the oil flow rate.

[0014] The oil temperature sensor collects the oil temperature;

[0015] The displacement sensor collects the extension and retraction speeds and displacements of multiple sets of hydraulic cylinders;

[0016] The wind speed sensor monitors the on-site wind speed and issues strong wind warnings.

[0017] Furthermore, in step one, during the climb-up startup phase, the perception layer starts up in advance and completes parameter acquisition initialization;

[0018] During the ascent, the sensing layer continuously collects parameters at a high frequency;

[0019] During the climbing pause or adjustment phase, the sensing layer remains operational, monitoring the system status and environmental changes in real time.

[0020] Furthermore, in step two, the control layer includes a controller, which analyzes and processes parameters, compares the extension and retraction speeds and displacements of multiple sets of hydraulic cylinders in real time, determines whether the climbing of multiple sets of hydraulic cylinders is synchronized and whether the on-site wind speed exceeds the safety threshold, and determines whether the hydraulic system is operating stably.

[0021] Furthermore, in step two, if the sensing layer detects abnormal hydraulic pump pressure, abnormal oil temperature, abnormal oil flow, multiple sets of hydraulic cylinder extension and retraction speed differences exceeding the preset range, multiple sets of hydraulic cylinder displacement differences exceeding the preset range, or on-site wind speed ≥12.5m / s, it is determined to be an abnormal state.

[0022] Furthermore, in step three, the execution layer includes a hydraulic power unit. When the controller determines that the hydraulic system is in a normal state, it generates a command to continue climbing and transmits it to the hydraulic power unit to ensure that the tower machine continues to climb steadily.

[0023] When an abnormal state is detected, an early warning command and an adjustment command are immediately generated. The early warning command triggers the alarm component to issue an alarm, and the adjustment command is transmitted to the hydraulic power unit. The hydraulic power unit adjusts the operating parameters of the hydraulic system according to the command.

[0024] Furthermore, in step three, if the on-site wind speed is ≥12.5m / s or the hydraulic system malfunctions and cannot be adjusted, a stop climbing command is generated to control the tower-building machine to stop climbing.

[0025] Furthermore, during the climbing preparation stage after the concrete pouring is completed, the monitoring system will only allow the climbing process to start after confirming that the concrete strength meets the climbing requirements.

[0026] During the dismantling phase of the climbing formwork, the monitoring system can be linked with the climbing formwork dismantling equipment. Through the sensing layer, it can monitor the stress and displacement status of the frame in real time during the dismantling process, provide guidance for the dismantling operation, and avoid the frame colliding with the bridge tower structure during the dismantling process.

[0027] Furthermore, the monitoring system includes a sensing layer, a control layer, and an execution layer. The sensing layer is installed on the tower-building machine, the hydraulic pump pressure sensor is installed at the hydraulic pump outlet, the cylinder extension / retraction sensor and displacement sensor are installed at the cylinder extension / retraction end, the oil flow sensor is installed on the main oil pipeline, the oil temperature sensor is located inside the oil tank, and the wind speed sensor is installed on the top of the tower-building machine frame. The sensing layer is connected to the controller, and the controller is connected to the hydraulic system.

[0028] Furthermore, the sensing layer is connected to the controller via a shielded cable, and the controller is connected to the hydraulic system via a control cable.

[0029] The beneficial effects of the present invention using the above structure are as follows: This solution proposes an intelligent monitoring system for the climbing of the main tower of a cable-stayed bridge, which can monitor key parameters of the climbing formwork in real time, provide timely warnings of potential risks, enhance construction safety, and dynamically correct deviations to ensure the smooth climbing of the formwork, thereby helping to improve the accuracy and quality of bridge tower construction and providing reliable data support for efficient construction.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] like Figures 1-4 As shown, this invention proposes an intelligent monitoring system for the climbing of a tower-building machine for a cable-stayed bridge main tower, including step one: parameter acquisition: during the climbing process of the tower-building machine, climbing parameters are acquired in real time through the sensing layer of the monitoring system;

[0037] Step 2: Data transmission and analysis: The collected parameters are transmitted to the control layer, which analyzes and processes the data, compares the extension and retraction speeds and displacements of multiple sets of hydraulic cylinders in real time, and determines the status of the hydraulic system.

[0038] Step 3: Instruction Issuance and Feedback: Based on the instructions from the control layer, the hydraulic system is adjusted accordingly to control the climbing of the tower crane.

[0039] In practical use, the climbing parameters are collected in real time through the sensing layer of the monitoring system, and then the parameters are transmitted to the control layer. The control layer analyzes and processes the data, determines the status of the hydraulic system, and finally adjusts the hydraulic system accordingly through the execution layer based on the instructions of the control layer. This controls the climbing of the tower crane, enables timely detection and handling of problems, and ensures the safety and stability of the tower crane's climbing.

[0040] In step one, the sensing layer includes hydraulic pump pressure sensor, cylinder extension and retraction sensor, oil flow sensor, oil temperature sensor, displacement sensor and wind speed sensor, etc.

[0041] The hydraulic pump pressure sensor collects the hydraulic pump pressure.

[0042] The hydraulic cylinder extension / retraction sensor collects the extension / retraction amount of the hydraulic cylinder.

[0043] Oil flow sensor collects oil flow data;

[0044] The oil temperature sensor collects the oil temperature;

[0045] Displacement sensors collect the extension and retraction speeds and displacements of multiple hydraulic cylinders;

[0046] Wind speed sensors monitor on-site wind speed and issue strong wind warnings.

[0047] In practical use, the sensing layer includes hydraulic pump pressure sensors, cylinder extension / retraction sensors, oil flow sensors, oil temperature sensors, displacement sensors, and wind speed sensors. These sensors collect parameters such as hydraulic pump pressure, cylinder extension / retraction, oil flow, oil temperature, extension / retraction speed and displacement of multiple cylinders, and on-site wind speed. By collecting data in real time from various sensors, comprehensive and accurate information is provided to the control layer, enabling accurate judgment of the hydraulic system's status and ensuring the normal operation of the tower crane.

[0048] In step one, during the climb-up startup phase, the perception layer starts up in advance and completes parameter acquisition initialization.

[0049] During the ascent, the sensing layer continuously collects parameters at a high frequency;

[0050] During the climb pause or adjustment phase, the perception layer remains operational, monitoring system status and environmental changes in real time.

[0051] In practical use, during the climbing start-up phase, the sensing layer starts in advance and completes parameter acquisition initialization; during the climbing process, it continuously acquires parameters at high frequency; during the climbing pause or adjustment phase, it maintains operation and monitors system status and environmental changes in real time. This ensures that the sensing layer can acquire relevant parameters in a timely and accurate manner at each stage of the tower crane's climbing, providing reliable data support for the control layer and ensuring that the hydraulic system can make timely adjustments according to the actual situation.

[0052] In step two, the control layer includes a controller. The controller analyzes and processes the parameters, compares the extension and retraction speeds and displacements of multiple sets of hydraulic cylinders in real time, determines whether the climbing of multiple sets of hydraulic cylinders is synchronized and whether the on-site wind speed exceeds the safety threshold, and determines whether the hydraulic system is operating stably.

[0053] In practical use, the control layer includes a controller. The controller analyzes and processes the parameters transmitted from the sensing layer, compares the extension and retraction speeds and displacements of multiple sets of hydraulic cylinders in real time, determines whether the cylinders are climbing synchronously and whether the on-site wind speed exceeds the safety threshold, thereby judging whether the hydraulic system is operating stably. Through the controller's analysis and processing of parameters, potential problems in the operation of the hydraulic system can be detected in a timely manner, providing a basis for subsequent control commands.

[0054] In step two, if the sensing layer detects abnormal hydraulic pump pressure, abnormal oil temperature, abnormal oil flow, multiple sets of hydraulic cylinder extension and retraction speed differences exceeding the preset range, multiple sets of hydraulic cylinder displacement differences exceeding the preset range, or on-site wind speed ≥12.5m / s, it is determined to be an abnormal state.

[0055] In practical use, if the sensing layer detects abnormal hydraulic pump pressure, abnormal oil temperature, abnormal oil flow, differences in extension / retraction speeds of multiple hydraulic cylinders exceeding a preset range, differences in displacement of multiple hydraulic cylinders exceeding a preset range, or an on-site wind speed ≥12.5m / s, it is determined to be an abnormal state. This clearly defined standard for determining abnormal states enables the monitoring system to promptly identify problems in the hydraulic system or environmental conditions, allowing for appropriate measures to be taken.

[0056] In step three, the execution layer includes a hydraulic power unit. When the controller determines that the hydraulic system is in a normal state, it generates a command to continue climbing and transmits it to the hydraulic power unit to ensure that the tower machine continues to climb steadily.

[0057] When an abnormal state is detected, an early warning command and an adjustment command are immediately generated. The early warning command triggers the alarm component to issue an alarm, and the adjustment command is transmitted to the hydraulic power unit. The hydraulic power unit adjusts the operating parameters of the hydraulic system according to the command.

[0058] In practical use, when the controller determines that the hydraulic system is in a normal state, it generates a continue climbing command and transmits it to the hydraulic power unit to ensure the tower-building machine climbs steadily and continuously. When an abnormal state is detected, it immediately generates a warning command and an adjustment command. The warning command triggers the alarm component to issue an alarm, and the adjustment command is transmitted to the hydraulic power unit, which adjusts the hydraulic system operating parameters according to the command. This achieves the function of automatically issuing corresponding commands based on the state of the hydraulic system, ensuring that the tower-building machine can climb smoothly under normal conditions and provide timely warnings and adjustments under abnormal conditions.

[0059] In step three, if the on-site wind speed is ≥12.5m / s or the hydraulic system malfunctions and cannot be adjusted, a stop climbing command is generated to control the tower-building machine to stop climbing.

[0060] In practical use, if the on-site wind speed is ≥12.5m / s or the hydraulic system malfunctions and cannot be adjusted, a stop climbing command will be generated to control the tower-building machine to stop climbing. In situations where strong winds or serious hydraulic system malfunctions prevent further climbing, the tower-building machine can be stopped in time to avoid safety accidents.

[0061] In the climbing preparation stage after the concrete pouring is completed, the monitoring system will only allow the climbing process to start after confirming that the concrete strength meets the climbing requirements.

[0062] During the dismantling phase of the climbing formwork, the monitoring system can be linked with the climbing formwork dismantling equipment. Through the sensing layer, it can monitor the stress and displacement status of the frame in real time during the dismantling process, provide guidance for the dismantling operation, and avoid the frame colliding with the bridge tower structure during the dismantling process.

[0063] In practical use, during the pre-climbing preparation phase after concrete pouring, the monitoring system only allows the climbing process to begin after confirming that the concrete strength meets the climbing requirements. During the formwork dismantling phase, the monitoring system can link with the formwork dismantling equipment, using a sensing layer to monitor the stress and displacement status of the scaffolding in real time during dismantling, providing guidance for the dismantling operation. This ensures that climbing only takes place when the concrete strength meets the requirements during the pre-climbing preparation phase, avoiding safety issues caused by insufficient strength. During the formwork dismantling phase, real-time monitoring provides guidance for the dismantling operation, preventing the scaffolding from colliding with the bridge tower structure.

[0064] The monitoring system includes a sensing layer, a control layer, and an execution layer. The sensing layer is installed on the tower-building machine. The hydraulic pump pressure sensor is installed at the hydraulic pump outlet. The cylinder extension and retraction sensors and displacement sensors are installed at the cylinder extension and retraction ends. The oil flow sensor is installed on the main oil pipeline. The oil temperature sensor is located inside the oil tank. The wind speed sensor is installed on the top of the tower-building machine frame. The sensing layer is connected to the controller, and the controller is connected to the hydraulic system.

[0065] In practical use, the monitoring system comprises a sensing layer, a control layer, and an execution layer. The sensing layer is installed on the tower-building machine. Various sensors, such as the hydraulic pump pressure sensor, are installed at the hydraulic pump outlet; the cylinder extension / retraction sensor and displacement sensor are installed at the cylinder extension / retraction end; the oil flow sensor is installed on the main oil line; the oil temperature sensor is located inside the oil tank; and the wind speed sensor is installed on the top of the tower-building machine frame. The sensing layer is connected to the controller, and the controller is connected to the hydraulic system. This clearly defines the composition and installation locations of the monitoring system, ensuring that the system can accurately collect relevant parameters and achieve effective communication and control between the layers.

[0066] The sensing layer is connected to the controller via a shielded cable, and the controller is connected to the hydraulic system via a control cable.

[0067] In practical use, the sensing layer is connected to the controller via a shielded cable, and the controller is connected to the hydraulic system via a control cable.
