Description

Technical Field

[0001] This invention relates to the field of ballastless track construction technology, and more specifically to an intelligent equipment control system for ballastless track. Background Technology

[0002] CRTSⅢ type slab track, with its advantages of high smoothness and high stability, is widely used in high-speed railway construction. Track slab fine-tuning and clamping are key steps in ballastless track construction, directly affecting the quality of the track project. In existing technologies, intelligent fine-tuning vehicles have achieved automatic track slab gripping and fine-tuning, but clamping fixtures mostly use traditional mechanical structures, only achieving simple limit functions and lacking precise monitoring and local visualization of constraint pressure and lateral displacement. Furthermore, the fine-tuning equipment and clamping fixtures operate independently, and data cannot be interconnected and shared, leading to asynchronous fine-tuning and constraint, which can easily cause problems such as track slab displacement and floating.

[0003] Although some existing clamping fixtures have been equipped with pressure sensors, they can only achieve remote data transmission or simple statistics, lacking local real-time display and lateral displacement monitoring functions. Operators need to rely on the central control unit or handheld terminal to view pressure data, resulting in poor operation convenience; they cannot provide timely feedback on constraint status; and the clamping fixture and the fine-tuning car cannot communicate, resulting in poor compatibility between the two.

[0004] Therefore, it is necessary to propose an intelligent equipment control system for ballastless track to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the problems that existing clamping fixtures, although partially equipped with pressure sensors, can only achieve remote data transmission or simple statistics, lacking local real-time display functions. Operators need to rely on the central control unit or handheld terminal to view pressure data, resulting in poor operational convenience. Furthermore, they cannot provide timely feedback on constraint status, and the clamping fixture and the fine-tuning car cannot communicate, leading to poor compatibility between the two. This invention provides an intelligent equipment control system for ballastless track.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A ballastless track intelligent equipment control system includes: The intelligent fine-tuning subsystem is used for the rough positioning, attitude detection and precise adjustment of the track slab, including the ballastless track intelligent fine-tuning train, total station and at least 6 sets of fine-tuning reference frames; The intelligent vehicle dispatching system is equipped with a first communication module; The clamping fixture subsystem is used for limiting and fixing, pressure monitoring and local display of the track slab after fine adjustment. It includes at least 4 sets of gate-type clamping devices. Each set of gate-type clamping devices integrates a pressure sensing module, a pressure digital display screen, a second communication module and a lateral displacement sensing module. The pressure sensing module is used to collect the vertical constraint pressure value of the track slab and the value detected by the lateral displacement sensing module in real time. The pressure digital display screen is electrically connected to the pressure sensing module and the lateral displacement sensing module and is used to display the constraint pressure value locally in real time. The central control unit is communicatively connected to the intelligent fine-tuning subsystem and the clamping tooling subsystem, and includes a data storage module, a data processing module, and a decision command module. The data processing module is used to fuse and analyze the track slab attitude data and constraint pressure data, and the decision command module is used to generate fine-tuning adjustment commands or clamping parameter correction commands.

[0007] Furthermore, the gate-type clamping device also includes an integrated crossbeam, a pressure plate, lateral limiting bolts, anchor bolts, and a cutting edge. The pressure sensing module is located at both ends of the bottom of the integrated crossbeam, the pressure plate is located at the bottom of the pressure sensor, and the lateral displacement sensing module is located between the lateral limiting bolts and the side of the track plate to monitor the lateral displacement in real time with a measurement accuracy of ≤±0.05mm. The pressure digital display screen is installed at the end of the integrated crossbeam and is electrically connected to the pressure sensing module.

[0008] Furthermore, the pressure sensing module has a measurement range of 0-200 N·m and a measurement accuracy of ≤±1 N·m.

[0009] Furthermore, the central control unit is also equipped with a data visualization module for real-time display of the track slab centerline position deviation, elevation deviation, and constraint pressure value.

[0010] Furthermore, the first and second communication modules use local area network communication, and the central control unit establishes remote communication with the handheld terminal and the cloud management system.

[0011] A method for controlling a control system, characterized by comprising the following steps: S1: Construction preparation stage, complete the construction and strength testing of the concrete base, and ensure that the base strength reaches more than 75% of the design strength; S2: Track slab rough laying and positioning. The track slab is hoisted to the construction area by hoisting equipment for rough laying, controlling the longitudinal deviation to ≤10mm and the lateral deviation to ≤10mm. S3: Track slab fine-tuning inspection. The track slab is freely set up using a total station, and the initial attitude data of the track slab is collected using a fine-tuning frame. The initial attitude data includes the centerline position, the elevation of the rail bearing surface at the measuring point, and the relative deviation of the joints between adjacent track slabs. The initial attitude data is uploaded to the central control unit. S4: Coordinated adjustment control. The central control unit generates fine-tuning commands based on the initial attitude data and controls the intelligent fine-tuning vehicle to perform track slab attitude adjustment. S5: Installation of the clamping fixture: Install the support structure of the gate-type clamping device on the left and right sides of the track plate, adjust the lateral limit bolts to leave a 1-2cm gap with the side of the track plate, initialize and calibrate the pressure sensing module, displacement sensing module and pressure digital display screen to ensure normal display of the digital display screen, the clamping fixture subsystem collects and uploads constraint pressure data and lateral displacement data in real time, when the pressure value exceeds the range of 60-70 N·m or the lateral displacement exceeds ±0.5mm, the central control unit generates a clamping parameter correction command to adjust the torque of the lateral limit bolt or anchor bolt; S6: Fine-tuning and verification. After the track slab attitude is adjusted to within the allowable deviation range (centerline position ±0.5mm, elevation ±0.5mm), the clamping tooling subsystem performs the final locking. The pressure value is confirmed to be stable within the target range through the pressure digital display screen. The central control unit controls the total station to perform a retest. After confirming that the deviation meets the requirements, all construction data is saved. S7: Subsequent process connection, complete the self-compacting concrete pouring and curing. During the curing period, the clamping tooling subsystem continuously monitors the constraint pressure status of the track slab. The pressure digital display screen displays the monitoring data in real time. When an abnormal pressure is detected, an alarm is triggered in real time and the retest process is initiated.

[0012] Furthermore, in step S4, when the total station is set up freely, there are no fewer than 4 pairs of backsight CPⅢ control points, the working range of the station does not exceed 30m, there are no fewer than 2 pairs of backsight overlap points between adjacent stations, and the station establishment accuracy is ≤0.7mm.

[0013] Furthermore, when adjusting the track slab on the straight section, the tightening torque of the anchor bolts of the clamping device is controlled at 60-65 N·m, and the tightening torque of the outer anchor bolts on the curved section is controlled at 65-70 N·m. During the adjustment process, the left and right sides are operated simultaneously to avoid excessive force on one side. The operator can observe the change of pressure value corresponding to the torque in real time through the pressure digital display screen.

[0014] Furthermore, the re-measurement adopted two methods: CPⅢ free station and track benchmark forced centering, to ensure that the longitudinal position deviation of the track slabs was ≤5mm for straight sections and ≤2mm for curved sections. The relative lateral deviation of the bearing surface at the joint of adjacent track slabs was ≤±0.5mm, and no more than 3 consecutive track slabs were allowed to have the same deviation.

[0015] The beneficial effects of this invention are as follows: Achieving coordinated control of fine adjustment and clamping: The central control unit enables data interconnection and command coordination between the intelligent fine adjustment subsystem and the clamping tooling subsystem, solving the problem of independent operation and asynchronous adjustment of the two in the existing technology, and ensuring that the track plate completes stable constraint under precise attitude; (2) Dual protection of accurate pressure monitoring and local visualization: The clamping tool integrates a pressure sensing module, a lateral displacement sensing module and a pressure digital display screen, which can realize digital control of the constraint process and display the pressure value locally in real time. Operators can view it intuitively without relying on remote equipment, greatly improving the convenience of operation, while avoiding adjustment delay caused by data transmission delay. (4) Reduce reliance on manual labor and operational difficulty: The central control unit automatically completes data fusion, decision-making and instruction issuance. Combined with the intuitive display of the pressure digital display screen, workers only need to perform operations according to instructions and local display values, which reduces the requirements for the comprehensive business capabilities of operators. At the same time, the data is automatically stored and uploaded, which facilitates quality traceability. (5) Strong adaptability: By optimizing the cutting edge and pressure plate structure of the clamping tool, it meets the adjustment space requirements of the superelevation section of the curve. It is suitable for various working conditions such as viaducts, roadbeds, and tunnels. Moreover, the pressure digital display screen is installed at the end, which does not affect the construction operation and the constraint effect of the track slab. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please refer to Figures 1-2, which show an intelligent equipment control system for ballastless track, including an intelligent fine-tuning subsystem, a clamping tooling subsystem, and a central control unit.

[0020] The core components of the intelligent fine-tuning subsystem include a ballastless track digital fine-tuning car, a high-precision total station, and fine-tuning reference frames. After the fine-tuning car is in place, it first performs a warning scan, equipped with a track slab scanning and warning system, which automatically scans and identifies the size, model, and warping deformation of the track slab. If an error in the slab shape or warping >2mm is detected, an alarm is automatically triggered, and the track slab cannot be grabbed, thus achieving digital fine-tuning and full-process monitoring. The total station uses a Leica TS60 or higher precision model, which collects track slab attitude data through a free station setting method, with a station setting accuracy ≤0.7mm. There are a total of 6 fine-tuning reference frames, which are respectively arranged in the second pair of rail bearing bolt holes of the track slab to be adjusted and the track slab that has been fine-tuned, to achieve accurate detection of the track slab attitude.

[0021] The clamping fixture subsystem consists of at least four sets of portal clamping devices. Each set adopts an integrated design, including a crossbeam 1, a pressure plate 5, lateral limit bolts 4, a cutting edge 6, a pressure sensing module 7, a lateral displacement sensing module, anchor bolts 3, and a pressure digital display screen 2. The cutting edge 6 is a wedge-shaped block with a small bottom area to increase friction and prevent longitudinal displacement. The anchor bolts 3 are set on the bottom plates at both ends, and the lateral limit bolts 4 are set on the sides at both ends. The key improvement lies in the integration of the pressure sensing module 7 and the pressure digital display screen 2: the pressure plate 5 is positioned between the pressure sensing module 7 and the track plate for real-time... The system collects vertical constraint pressure with a measurement accuracy of ≤±1N・m; the lateral displacement sensing module is located between the lateral limit bolt and the side of the track plate to monitor the lateral displacement in real time with a measurement accuracy of ≤±0.05mm; the pressure digital display screen 2 is installed at the end of the integrated crossbeam 1 and is connected to the pressure sensing module 7 via a wired connection to achieve local real-time display of constraint pressure with a display accuracy of ≤±0.1N・m, rapid response, and support for abnormal alarms. All sensing data is uploaded to the central control unit in real time through the second communication module, achieving dual protection of local display and remote monitoring.

[0022] The central control unit is the core hub of the system, including data storage, processing, and decision-making command modules. The data processing module integrates track slab attitude data and constraint pressure data, and uses algorithms to analyze and determine the track slab status. The decision-making command module generates fine-tuning instructions or clamping parameter correction instructions based on the analysis results, and issues them to the intelligent precision-tuning machine and clamping tooling, respectively. The central control unit is also equipped with a data visualization module, which supports data statistical analysis and remote transmission to handheld terminals and cloud management systems.

[0023] This invention also discloses the control method of the above-mentioned control system, including seven steps: construction preparation, track slab rough laying, fine adjustment and testing, coordinated adjustment control, installation, fine adjustment and verification of clamping fixture, and subsequent process connection. In the coordinated adjustment stage, the central control unit controls the fine adjustment vehicle and clamping fixture simultaneously based on the fusion analysis of fine adjustment data and pressure and lateral displacement monitoring data. The operator can view the pressure value in real time through the pressure digital display screen 2 and quickly respond to adjustment commands. Differentiated clamping torque control is adopted for straight sections and curved sections to avoid uneven force on the track slab. In the retesting stage, the pressure stability is confirmed through the digital display screen, and the attitude accuracy is verified by combining two methods to ensure construction quality.

A total of 144 sets of support devices and 168 sets of crimping devices are configured for a single-line 6-hole 32.6m beam segment.

[0026] Central control unit: Equipped with an industrial control computer and dedicated data processing software, supporting real-time data acquisition, fusion analysis, command issuance, and visualization. Data communication utilizes a 5G local area network with a transmission latency of ≤50ms, and also supports data synchronization with handheld devices and cloud management platforms.

[0027] Installation process: First, complete the construction of the concrete base, which is 290cm wide and 20cm thick. After the base reaches 75% of the design strength, lay the isolation layer and elastic pad layer. After the track slab is roughly laid, complete the total station setup and fine-tuning frame installation. The digital fine-tuning car completes the fine-tuning operation. Install the gate-type clamping device, adjust the lateral limit bolt 4 to leave a 1-2cm gap, connect the pressure sensor module 7 to the digital display screen, complete the initialization calibration, and ensure that the digital display screen displays normally. After fine-tuning and verification, the overall system debugging is ready.

[0028] The operation steps for ballastless track construction using the above system are as follows: S1: Construction preparation, the concrete strength of the base reaches 30MPa after rebound testing, reaching 75% of the design strength; S2: The track slab is roughly laid. The track slab is lifted to the construction area by a 10t gantry crane on the beam surface. The longitudinal deviation of the rough laying is ≤8mm and the transverse deviation is ≤7mm. The support device is installed at the lifting sleeve position of the track slab and the tightening torque is 250N・m to ensure that the support is in close contact with the side of the track slab. S3: Track slab fine-tuning test. The total station is set up freely within the CPⅢ network, backsights 8 CPⅢ control points, and the station establishment accuracy is 0.6mm. The fine-tuning frame is set up on the second pair of rail bearing platforms of the track slab to be adjusted and the track slab that has been fine-tuned, and the initial attitude data is collected. The centerline position deviation is +1.2mm and the elevation deviation is -0.8mm. The data is uploaded to the central control unit. S4: Coordinated adjustment control, the central control unit generates fine adjustment commands to control the intelligent fine adjustment vehicle to grab the track slab and adjust its posture; S5: Install the clamping fixture, install the gate-type clamping device, leave a 1.5cm gap between the transverse limit bolt 4 and the side of the track plate, connect the power supply to the pressure digital display screen 2, complete the calibration of the sensor and the digital display screen, the digital display screen displays the initial pressure value of 0 N·m, the clamping fixture collects pressure data in real time, and uploads it synchronously to the central control unit and the end digital display screen. When the digital display screen displays a pressure value of 58 N·m (below the lower limit of 60 N·m), the system automatically issues a correction command. The operator, in conjunction with the real-time value on the digital display screen, adjusts the tightening torque of the anchor bolts on the outside of the curve to 68 N·m, and the digital display screen synchronously displays a pressure value of 67.2 N·m. Finally, the track plate attitude deviation is corrected to the centerline position +0.3mm and the elevation -0.2mm. S6: Fine-tuning and verification. The pressure values ​​of the four sets of clamping devices are confirmed to be stable in the range of 65-68 N·m through the pressure digital display screen 2. The central control unit controls the total station to re-measure using two methods: CPⅢ free station and forced centering of the track reference point. All deviations are within the allowable range. The data is saved to the cloud. S7: Self-compacting concrete pouring and curing. During the pouring process, the pressure value is continuously monitored by the clamping device and displayed in real time on the digital display screen. The pressure is always stable within the target range. The clamping device is removed after 1 day of curing.

[0029] In this embodiment, the fine adjustment and clamping of a single track slab takes about 15 minutes, which is 5 minutes shorter than the traditional process. The construction accuracy fully meets the requirements of CRTSⅢ type slab track. Moreover, the operator can quickly grasp the pressure status through the end digital display screen without having to frequently check the remote terminal, which significantly improves the convenience of operation. No problems such as track slab floating or displacement have occurred.
