[0002] During railway construction, the process is divided into base plate construction and track bed slab construction. During track bed slab construction, track frame is used for positioning to ensure the positional accuracy of the sleepers after installation and to achieve the purpose of limiting movement, so that the cast track bed slab meets the construction requirements.

[0003] After installation, existing track panels are typically calibrated using a fine-tuning trolley that runs along the track, followed by adjustment. This adjustment method requires repeated measurement and adjustment at the same location, which severely impacts overall construction efficiency. Furthermore, the adjustment process can easily cause the track panels to shift, affecting overall construction accuracy. Therefore, the installation and fine-tuning of track panels under current technology requires extensive experience in adjustment and construction, placing extremely high demands on construction techniques.

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.

[0018] Please see Figures 1 to 5 The present invention provides a technical solution: Example 1: A high-precision automatic positioning system for rail panel frames. The automatic positioning system includes a measurement module installed on an adjustable rail panel frame 1 and a processing module located on a central control host. An adjustable support mechanism that can be adjusted longitudinally, laterally, and rotatably is installed on the rail panel frame 1. The rail panel frame 1 is installed on the upper end of a base plate 5. A steel frame cage 7 is provided on the base plate 5. Multiple sets of sleepers 6 are laid on the steel cage 7 at intervals. The main body of the rail panel frame 1 is pressed and installed on the sleepers 6. Four sets of support legs 8 are provided on the outer side of the base plate 5. The four sets of support legs 8 are connected to the rail panel frame 1. A longitudinal adjustment mechanism 13 that can adjust the longitudinal height, a lateral adjustment mechanism 14 that can adjust the lateral position, and a rotation mechanism 12 that can adjust the angle are provided between the support legs 8 and the rail panel frame 1. The longitudinal adjustment mechanism 13, the lateral adjustment mechanism 14, and the rotation mechanism 12 are all driven by servo motors. The servo motors are controlled by a computer terminal through a wireless transmission module 4.

[0019] The adjustable support mechanism enables precise positional adjustment of the rail frame 1.

[0020] The measurement module includes a measuring prism 3 and a wireless transmission module 4 mounted on the track frame 1. The processing module includes a computer terminal with processing software and a total station that works with the measuring prism 3 to perform measurements. The processing module is electrically connected to the adjustable support mechanism on the track frame 1 via the wireless transmission module 4. The main body of the track frame 1 includes a pair of longitudinal beams 11 pressed onto the sleepers 6. The pair of longitudinal beams 11 are spaced parallel to each other and are fixedly connected by spaced crossbeams 15. The crossbeams 15 are vertically installed between the pair of longitudinal beams 11. The wireless transmission module 4 is fixedly installed on the crossbeams 15. The processing module includes a wireless communication base station and a base station antenna. The wireless transmission module 4 transmits the detected information to the computer terminal via the wireless communication base station and the base station antenna.

[0021] By designing a "slab-type" track frame 1, the overall strength meets the requirements for converting the construction of double-block ballastless track bed slabs to Type III slab construction. Fine-tuning of this project is completed by simulating Type III slab measurement and fine-tuning. The control system of the entire system is completed by a laptop computer + control software + wireless communication base station + base station antenna. The track fine-tuning trolley is no longer used. After the total station is set up freely, the control software installed on the laptop computer controls the total station to complete all measurement, calculation and control work.

[0022] The measuring prism 3 is set in two sets, and the measuring module also includes a pair of tilt sensors 2. The measuring prism 3, tilt sensors 2 and wireless transmission module 4 are set as a set of measuring components. At least one set of measuring components is set on the crossbeams 15 at both ends of the track frame 1.

[0023] Working principle: The total station measures the two measuring prisms 3 on the track frame 1, and reads the values ​​of the two tilt sensors 2 through the wireless data module 4. Based on the coordinates of the measuring prisms 3 and the data of the tilt sensors 2, the height and lateral adjustment values ​​of the four legs 8 are calculated. After the calculation is completed, the data is transmitted to the wireless communication module 4 on the four legs 8, and the servo motors automatically adjust to the calculated position.

[0024] After the first adjustment, the two measuring prisms 3 on the track frame 1 are re-measured using a total station, and the values ​​of the two tilt sensors 2 are read through the wireless data module 4. The difference between the height of the four legs 8 and the lateral adjustment value is calculated based on the coordinates of the measuring prisms 3 and the data of the tilt sensors 2. If the difference is less than the limit, the adjustment of the track frame 1 is completed; if the residual is greater than the limit, the adjustment is repeated until the limit meets the requirements.

Step 3: After the first adjustment is completed, measure the prism 3 on the track panel frame 1 using a total station; Step 4: Calculate the difference between the height of the four support legs 8 and the lateral adjustment value based on the measured data. If the difference is less than the limit, the adjustment of the track frame 1 is complete; if the residual difference is greater than the limit, repeat the adjustment until the limit meets the requirements.

[0026] Example 2: Based on Example 1, the measuring prism 3 is set to four groups, and the four groups of measuring prism 3 are all installed on the longitudinal beam 11. The connection position of the support leg 8 and the longitudinal beam 11 on the rail frame 1 coincides with the installation position of the measuring prism 3.

[0027] The total station measures the four measuring prisms 3 on the track frame 1, and calculates the height and lateral adjustment values ​​of the four support legs 8 based on the coordinates of the measuring prisms 3. After the calculation is completed, the data is transmitted to the wireless communication module 4 on the four support legs 8, and the servo motor automatically adjusts to the calculated position.

[0028] The center line of the track panel is located by measuring prism 3 using a total station, the elevation of the track panel is measured, and the left and right height difference of the track panel frame 1 is measured. The data is then transmitted to a laptop computer for data processing and then transmitted to the adjustable support mechanism for automatic fine adjustment.
