Description

Technical Field

[0001] This invention relates to the field of large component installation technology in municipal engineering and infrastructure construction, and in particular to a large component overall jacking and guiding system and method, which is applicable to the overall jacking construction of long-span, heavy-weight components in scenarios such as bridge engineering, steel structure of industrial plants, and foundation of large equipment. Background Technology

[0002] In municipal engineering and large-scale infrastructure projects, the overall jacking construction of components such as bridge box girders, industrial plant boiler units, and large equipment foundations is a critical installation stage. During the jacking process, components are easily affected by various factors such as uneven jacking force, foundation settlement, uneven distribution of component self-weight, and deviations in track flatness, which can easily lead to problems such as lateral displacement, axis deviation, and attitude instability. Once the deviation exceeds the allowable range, it will not only result in substandard component positioning accuracy, but may also cause collisions between components and surrounding structures, local stress concentration, or even structural damage, causing significant safety and economic losses.

[0003] Currently, the attitude control of large component jacking construction mainly relies on the following two technical approaches: The first category involves manual monitoring and adjustment of the path. During construction, operators regularly use measuring instruments such as total stations and levels to manually observe key points of the components, record the data, calculate the deviation value manually, and then manually adjust the jacking force or jacking speed of the hydraulic jacks. This approach has significant drawbacks: First, the response is severely delayed. Manual monitoring intervals are typically tens of minutes or even longer, making it impossible to capture instantaneous changes in the component's attitude in real time. By the time a deviation is detected, the component has often already deviated considerably, significantly increasing the difficulty of correction. Second, the accuracy is low. Human error is easily introduced during manual reading, recording, and calculation, and manual adjustment of the jacking force is difficult to achieve precise control, resulting in poor correction effects. Repeated adjustments may even exacerbate component oscillations. Third, the safety is poor. When a component deviates significantly due to sudden factors (such as local foundation settlement or guide wheel jamming), the manual emergency response is slow, making it impossible to promptly stop jacking or quickly correct the deviation, which can easily lead to safety accidents such as component overturning or collisions. Fourth, the economy is poor. It requires a large investment of manpower for continuous monitoring and repeated adjustments, resulting in high labor costs, and frequent work stoppages cause delays in progress.

[0004] The second category is a simplified automated monitoring path. Some projects use fixed sensors or simple displacement monitoring devices to replace manual readings, but they still lack closed-loop control linkage with the jacking actuator. The monitoring data is only used for alarm prompts, and manual intervention is still required for adjusting the jacking force. Although this path increases the data acquisition frequency to some extent, it does not fundamentally solve the problem of the broken "monitoring-analysis-execution" closed loop. The level of automation is low, making it difficult to meet the needs of projects with extremely high construction accuracy requirements, such as large industrial park infrastructure and long-span bridges.

[0005] Therefore, there is an urgent need for a jacking guidance system that can achieve real-time monitoring, intelligent analysis, automatic correction, and graded early warning, in order to replace the traditional manual intervention mode and fundamentally improve the safety, accuracy, and efficiency of jacking construction of large components. Summary of the Invention

[0006] The present invention aims to solve the problems of delayed monitoring response, low correction accuracy, untimely response to sudden risks, and high labor costs in the existing technology during the jacking construction of large components.

[0007] This invention provides a large-scale integral jacking and guiding system for structural members, comprising a measurement and monitoring module, a computer-controlled self-correction system, and a jacking device arranged sequentially and communicatively along the jacking direction. The measurement and monitoring module includes multiple sets of prisms deployed on the member and a fully automatic total station for real-time measurement of the spatial coordinates of each prism. The computer-controlled self-correction system is used to construct a real-time three-dimensional model of the member's attitude based on the spatial coordinate data, calculate the deviation value and deviation rate, automatically match a correction strategy and generate correction commands based on the magnitude of the deviation value, and execute graded early warnings based on preset thresholds. The jacking device includes multiple jacking units symmetrically arranged on both sides of the member's bottom, a hydraulic control system, and a guiding mechanism. The hydraulic control system adjusts the hydraulic oil pressure of each jacking unit via electromagnetic proportional valves according to the correction commands. The guiding mechanism includes arc-shaped liners on both sides of the member, used to automatically return the member to a predetermined trajectory using lateral gravity when the member deviates.

[0008] Preferably, the prism group is arranged at four key monitoring points at the corners and ends of the component. Each prism group contains at least two prisms. The front and rear rows of prism groups are arranged with staggered elevations, with the staggered height controlled at 20cm. The prism group is fixed to the surface of the component with bolts, thereby ensuring that the field of view of each monitoring point is unobstructed, the data is continuous and stable, and the prisms are prevented from loosening and shifting due to vibration, thus providing a reliable raw data basis for attitude analysis.

[0009] Preferably, the computer-controlled self-correction system includes an attitude analysis module, an instruction generation module, and an early warning module. The attitude analysis module is used to construct a real-time three-dimensional model of the component's attitude using three-dimensional modeling software, compare the real-time attitude parameters with preset standard parameters, calculate the deviation value and deviation rate, and analyze the deviation development trend, thereby transforming discrete spatial coordinate data into quantifiable attitude deviation indicators, providing a decision-making basis for the accurate matching of subsequent correction strategies.

[0010] Preferably, the instruction generation module has multiple built-in correction strategies and automatically matches them according to the magnitude of the deviation: when the deviation is less than a preset threshold, a proportional adjustment strategy is adopted, with the adjustment range being proportional to the deviation to achieve smooth correction; when the deviation is greater than or equal to the preset threshold, a graded adjustment strategy is adopted, first correcting the deviation quickly with a larger range, and then switching to fine adjustment when the deviation approaches the threshold to ensure the accuracy of correction, thereby avoiding insufficient response of a single adjustment strategy for small deviations or overshoot oscillation for large deviations, and achieving adaptive and precise control under different degrees of deviation.

[0011] Preferably, the early warning module presets two levels of early warning thresholds: the first level of early warning threshold is when the deviation value reaches 80% of the allowable deviation and the duration is not less than 2 seconds. After being triggered, a yellow audible and visual warning signal is issued and the jacking device is automatically controlled to reduce the jacking speed to 50% of the original speed; the second level of early warning threshold is when the deviation value exceeds the allowable deviation. After being triggered, a red audible and visual warning signal is issued and the jacking is suspended within 0.3 seconds. This allows for early deceleration and buffering when the construction deviation approaches the dangerous boundary, and rapid braking when a sudden large deviation occurs, forming a graded safety defense line from slow to rapid.

[0012] Preferably, the hydraulic control system includes a hydraulic pump station, an electromagnetic proportional valve, and a pressure sensor. After receiving the correction command, the electromagnetic proportional valve precisely controls the hydraulic oil pressure of each jack, with an adjustment response time of less than 0.5s. This allows the computer-generated digital command to be quickly converted into a precise adjustment of the physical thrust, shortening the closed-loop response time from deviation identification to force correction and improving the real-time performance of the correction.

[0013] Preferably, the guiding mechanism includes arc-shaped liner plates on both sides of the component. When the component deviates significantly, the rolling device climbs along the arc-shaped liner plates, and the component's own weight generates a lateral force, thereby automatically returning to the predetermined pushing trajectory. Thus, based on the active adjustment of the hydraulic correction system, a passive mechanical guiding constraint is superimposed to form a composite guiding mechanism that combines active control and passive correction, improving the return reliability under large deviation conditions.

[0014] This invention offers the following advantages: By acquiring real-time spatial coordinates through a measurement and monitoring module, performing intelligent attitude analysis and adaptive correction strategy matching through a computer-controlled self-correction system, utilizing the rapid hydraulic response of the jacking device, and employing the gravity self-regression constraint of the guiding mechanism, a closed-loop control system of "real-time monitoring - intelligent analysis - precise execution - mechanical constraint" is constructed. This replaces the traditional manual monitoring and adjustment mode, solving the technical problems of delayed response, low accuracy, and poor safety in the jacking construction of large components, and significantly improving construction accuracy, safety, and automation levels.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] A large component integral jacking and guiding system includes a measurement and monitoring module, a computer-controlled self-correction system, and a jacking force device.

[0020] The measurement and monitoring module includes prism group 1, fully automatic total station 2, and a communication transmission unit. Prism group 1 is arranged at four key monitoring points at the corners and ends of the component. Each prism group contains at least two prisms, and the front and rear rows of prism groups are staggered in elevation, with the stagger height controlled within 20cm to ensure that the prisms in the front and rear rows do not obstruct each other. Prism group 1 is fixed to the surface of the component with bolts to prevent the prisms from loosening or shifting due to vibration during the jacking process. The fully automatic total station 2 is located behind the jacking equipment and is used to continuously measure the spatial coordinate data of each prism group in real time, and automatically uploads it to the computer self-control correction system through the communication transmission unit.

[0021] The computer-controlled automatic correction system includes an industrial control computer (3), a data acquisition card, a communication module, and a software system. The software system adopts a modular design, including an attitude analysis module (4), a command generation module (5), and an early warning module (6).

[0022] The attitude analysis module 4 uses preprocessed spatial coordinate data to construct a real-time attitude 3D model of the component using 3D modeling software. It compares the real-time attitude parameters (lateral displacement, deviation value, tilt angle) with preset standard parameters, calculates the deviation value and deviation rate using the least squares method, and analyzes the deviation development trend.

[0023] The instruction generation module 5 incorporates multiple correction strategies and automatically matches them based on the deviation value. When the deviation value is less than a preset threshold, a proportional adjustment strategy is adopted, with a proportional coefficient Kp=0.2. That is, for every 1mm increase in deviation, the jacking force adjustment range increases by 2%, achieving smooth correction and avoiding overshoot. When the deviation value is greater than or equal to the preset threshold, a tiered adjustment strategy is adopted: the first-level adjustment range is 20%, quickly correcting the deviation; when the deviation drops to 1.2 times the preset threshold, it switches to the second-level fine adjustment, with a proportional coefficient Kp=0.1, ensuring correction accuracy. After the instruction is generated, it is transmitted to the jacking device via the communication module.

[0024] The early warning module 6 has two preset early warning thresholds. The first-level early warning threshold is triggered when the deviation reaches 80% of the allowable deviation and lasts for no less than 2 seconds. Upon triggering, a yellow audible and visual warning signal is issued, and the jacking device is automatically controlled to reduce the jacking speed to 50% of its original speed. The second-level early warning threshold is triggered when the deviation exceeds the allowable deviation. Upon triggering, a red audible and visual warning signal is issued, and the jacking is paused within 0.3 seconds. The jacking device maintains the current thrust to prevent component rebound. The system records the current attitude parameters and fault timestamp and saves them to local storage, waiting for manual troubleshooting and recovery through manual adjustment.

[0025] The jacking device includes a jacking unit 7, a hydraulic control system 8, and a guiding mechanism 9.

[0026] The jacking unit 7 uses a large-tonnage hydraulic jack, with a rated jacking force of 500kN per unit, a maximum stroke of 300mm, and a piston diameter of 600mm. Based on the weight of the component and the jacking requirements, jacking units are symmetrically arranged on both sides of the bottom of the component, with 3-5 jacking units on each side. The spacing between the jacking units is determined according to the stress characteristics of the component to ensure uniform distribution of the jacking force.

[0027] The hydraulic control system 8 includes a hydraulic pump station, electromagnetic proportional valves, and pressure sensors, and is connected to a computer-controlled automatic correction system. Upon receiving adjustment commands, it precisely controls the hydraulic oil pressure of each jack through the electromagnetic proportional valves, thereby adjusting the jacking force. The adjustment response time is less than 0.5 seconds, achieving rapid correction.

[0028] The guiding mechanism 9 includes arc-shaped liners on both sides of the component. The surface of the arc-shaped liners is filled with grease and equipped with spherical balls. When the component deviates significantly from the predetermined jacking track, the rolling device climbs along the arc-shaped liners. Due to the lateral force generated by the component's own weight, it automatically returns to the predetermined jacking trajectory.

[0029] Based on the above system, the present invention also provides a method for guiding the overall jacking of large components, the specific steps of which are as follows: System initialization: Based on the component's dimensions, weight, material, and jacking path, the standard posture parameters, deviation thresholds, and safety warning thresholds for each construction stage are preset through the computer-controlled self-correction system. Initial state coordinate acquisition is completed using the fully automatic total station. The station is freely set up using the jacking start and end points. After setting up the station, the coordinates of the jacking start point are collected again and uploaded to the computer system as the jacking baseline. Relative coordinates are then collected for each prism group sequentially to establish the relative positional relationship between each prism and the jacking baseline, serving as the initial zero-point data for the prism group.

[0030] Real-time data acquisition: After the jacking construction is started, the jacking speed is set to 1mm / s, and the fully automatic total station continuously measures the spatial coordinate data of each prism group in real time, automatically completing the real-time acquisition and uploading of point data.

[0031] Attitude analysis and judgment: The computer-controlled self-correction system updates the real-time attitude 3D model of the component in real time, quantifies and compares the real-time parameters with the preset standard parameters, calculates the deviation value and deviation rate through the least squares method, and determines the deviation development state.

[0032] Automatic deviation correction control: Graded control is implemented based on the deviation value. When the deviation is less than the adjustment threshold, the current jacking speed is maintained, and a proportional adjustment strategy is adopted, with the adjustment range directly proportional to the deviation value, and a proportionality coefficient Kp=0.2. For example, when the deviation is 3mm, the adjustment range is 6%, meaning the thrust of the jacking unit on the deviation side increases by 6%, and the thrust on the opposite side decreases by 6%, achieving smooth deviation correction. When the deviation is greater than or equal to the adjustment threshold, a graded adjustment strategy is adopted. The first level adjustment range is 20%. For example, if the right side of the component is deviated by 10mm, the computer-controlled deviation correction system generates an adjustment command, controlling the electromagnetic proportional valve of the right jacking unit to decrease the input voltage, reducing the jacking force by 20%, while simultaneously controlling the left jacking unit to increase the input voltage, increasing the jacking force by 20%. When the deviation drops to 5.5mm, it switches to the second level of fine adjustment, with an adjustment range of 5%, until the deviation value returns to the threshold range, restoring normal jacking parameters.

[0033] Early Warning and Emergency Response: A tiered response is implemented based on early warning thresholds. When the deviation reaches 80% of the allowable deviation and persists for 2 seconds, the system issues a yellow audible and visual warning signal and automatically controls the jacking device to reduce the jacking speed to 50% of its original speed. If a sudden factor causes the component deviation to exceed the safety warning threshold, the system immediately issues a red audible and visual warning signal, suspends jacking within 0.3 seconds, and automatically records and saves the current attitude parameters. After troubleshooting, construction personnel manually adjust the component's attitude at a low speed of 0.3 mm / s using the system's manual adjustment mode until the deviation drops to a safe range. Once no abnormalities are confirmed, automatic jacking is restarted.

[0034] Cyclic Monitoring: Throughout the jacking process, the system continuously and cyclically executes data acquisition, preprocessing, attitude analysis, deviation judgment, correction control, and early warning steps, with a cycle time not exceeding 20 seconds. When the component is jacked to 0.5m from the preset position, the jacking speed is automatically reduced to 0.5mm / s, the deviation threshold is adjusted to 3mm, and the system enters the fine alignment stage. When the component is jacked to the preset position, the system issues a jacking completion signal, thus completing the construction.

[0035] Variation Example 1: Planar Straight-Line Jacking Case Taking the jacking of a large rectangular boiler as an example, the component jacking is a straight-line movement in a plane with uniform vertical elevation. Six sets of sliding devices are used, and two sets of prisms are designed and arranged symmetrically. The total station is positioned behind the jacking equipment. The prisms are Leica 17.5mm prisms. The first set is fixed at the front end, 0.8m from both ends of the component, with the prism center elevation 0.1m higher than the component. The second set is fixed at the rear end, 0.5m from the rear end, with the prism center elevation 0.3m higher than the component. The jacking distance is 12.53m. The relative coordinates of the jacking start point are zero, and the coordinates of the end point are X: 0.000, Y: 12.530, with an elevation of 0. During construction, the system continuously monitors and adjusts according to the above-mentioned automatic correction control process. Thus, under straight-line jacking conditions without slope or curves, through standardized monitoring point layout and closed-loop correction control, the boiler is ensured to be accurately positioned along the design axis.

[0036] Variation Example 2: Curved jacking operation Taking the curved launching of a long-span bridge box girder as an example, the launching route includes a curve with a radius of R=500m. During the system initialization phase, based on the curve radius and component length, the plane coordinates and tangent angle parameters of each prism group in the curve section are added to the trajectory data compilation. When calculating the deviation value, the attitude analysis module matches the real-time coordinates with the corresponding mileage station of the curve trajectory, rather than simply comparing the straight line coordinates. When the component enters the curve section, the attitude analysis module calculates the lateral offset and tangential deflection angle of each prism group relative to the curve design trajectory in real time. The instruction generation module executes a proportional adjustment strategy based on the lateral offset. The arc-shaped liner of the guide mechanism provides additional lateral constraints on the outside of the curve section. Thus, under the curved launching condition of a long-span bridge, through the precise matching of trajectory coordinates and curve parameters and the mechanical guidance assistance of the arc-shaped liner, the attitude stability of the box girder in the curve is maintained, and outward slippage is avoided.

[0037] Variation Example 3: Slope jacking operation Taking the jacking of a large equipment foundation in an industrial plant along a slope as an example, the jacking route has a slope of 3%. During the system initialization phase, a longitudinal slope compensation value is added to the preset standard attitude parameters. When calculating the deviation value, the attitude analysis module incorporates vertical elevation data into the three-dimensional attitude model to distinguish between normal elevation changes and abnormal deviations caused by the slope. In the threshold setting of the early warning module, the deviation value is allowed to be appropriately relaxed in the slope section, but the tilt angle deviation threshold is tightened. When the component moves uphill along the slope, the instruction generation module automatically adjusts the reference jacking force of the jacking units on both sides according to the gravity component, so that the jacking force on the uphill side is greater than that on the downhill side, thus counteracting the downward trend caused by the slope. At the same time, the arc-shaped liner of the guide mechanism provides longitudinal guiding constraints at the slope change points. Therefore, under the jacking condition of a large slope, the synergistic effect of the slope compensation algorithm and the longitudinal constraints of the guide mechanism prevents the component from longitudinally sliding or overturning in the slope section due to uneven gravity components.

[0038] As can be seen from the above embodiments, compared with traditional methods, the technical solution of this application eliminates the monitoring process of regularly using total stations and levels for point observation, reading recording, and deviation calculation; it eliminates the repeated trial-and-error correction process of manually adjusting the jacking force or jacking speed of hydraulic jacks; it eliminates the supporting procedures of frequently pausing construction for correction checks due to long manual monitoring intervals; and it eliminates the safety risks and subsequent structural damage repair costs caused by slow manual emergency response in the event of sudden large deviations. Thus, the originally discrete "monitoring-calculation-adjustment" operation mode that relied heavily on manual intervention is integrated into a closed-loop control system with real-time monitoring, intelligent analysis, and automatic correction. This reduces the sources of error in manual monitoring, shortens the correction response cycle, and lowers the labor costs and safety risks of jacking large components.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
