Abstract
Description
Technical Field
[0001] The present invention belongs to the field of railway transportation, and in particular relates to a track plate position adjustment method, device, computer equipment and storage medium. Background Art
[0002] CRTS III slab track, a type of ballastless track independently developed in my country, has been widely installed on lines both domestically and internationally. CRTS III slabs primarily include the P5600, P4925, and P4856 models. To ensure the safe operation of high-speed trains, extremely high precision is required for the slabs' installation, with vertical and lateral accuracy requirements of ≤2mm. However, the size and weight of the slabs—for example, the P5600, which measures 2.5m x 5.6m and weighs approximately 7.5 tons—make high-precision adjustment of the slabs extremely challenging.
[0003] The main process for track slab fine-tuning involves: 1) installing fine-tuning claws at the track slab mounting holes; 2) installing prisms at the CP III points on both sides of the track, and setting up a total station at the track centerline where fine-tuning is required; 3) multiple workers simultaneously adjust the four fine-tuning claws based on commands from the fine-tuning terminal to bring the track slab's spatial position to the designed coordinates. However, existing fine-tuning procedures are primarily manual and require the coordination of multiple workers, resulting in a lengthy and time-consuming process.
[0004] The prior art provides a method for automatically adjusting the installation position of track plates. This method employs a technical solution that involves installing an adjuster on a fine-tuning claw. Based on the dimensional deviation between the rough-laid track plate position and the ideal position, a control console controls the rotation of a motor to drive the adjuster to adjust the fine-tuning claw, thereby adjusting the track plate's installation position. However, this technical solution only adjusts the dimensional deviation during the position adjustment process, and the spacing between the rough-laid track plate and the previously laid track plate is generally very close, typically less than 10 mm. This can lead to the following issues during the adjustment process: if the adjustment dimension entered by the control console based on the deviation is inappropriate, the track plate to be installed will press against the previously laid track plate and become unable to move further. This requires the track plate to be withdrawn a short distance from its original position before being readjusted, resulting in low efficiency. In summary, existing research primarily relies on traditional construction processes, improving some equipment to replace manual labor, but has failed to further improve the fine-tuning construction process, thereby enhancing the quality and efficiency of ballastless track laying. Summary of the Invention
[0005] In order to solve the above problems, the present invention provides a track plate position adjustment method, device, computer equipment and storage medium.
[0006] In order to achieve the above object, the present invention provides the following technical solutions: The track plate position adjustment method provided by the present invention has the following beneficial effects: This method uses a total station to obtain the coordinates of the fine-tuning vehicle's prism and establish a new coordinate system. Combined with the coordinated control of horizontal and vertical electric cylinders, it achieves precision and automation in the track plate fine-tuning process. Compared with traditional adjustment methods, this method first accurately calculates the electric cylinder's expansion and contraction through dynamic coordinate system conversion, allowing the track plate to be positioned to the preset position in one go. This completely solves the problem of traditional methods where input deviations cause the track plate to press against adjacent plates, requiring repeated plate withdrawal and readjustment. This significantly improves construction efficiency and avoids the shortcomings of traditional methods of repeated adjustments relying on experience, making the entire fine-tuning process more scientific and efficient. Therefore, this method excels in improving fine-tuning accuracy, reducing the number of adjustments, optimizing the adjustment process, and improving construction efficiency, providing strong technical support for high-speed railway ballastless track construction.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention and to be able to implement it, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.
[0019] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0020] First, the present invention provides a method for adjusting the position of a track plate, specifically as follows: Figure 1 As shown, the following steps are included: S101. Obtain the coordinates of the fine-tuning vehicle and the track plate through a total station, and establish a new coordinate system based on the fine-tuning vehicle.
[0021] Specifically, the spatial coordinates of the left prism, the right prism, and the rear prism of the fine-tuning vehicle can be obtained; the origin position of the new coordinate system is calculated based on the spatial coordinates; and the new coordinate system is constructed based on the origin position of the new coordinate system.
[0022] In one embodiment, the initial spatial positions of the fine-tuning vehicle and the track plate are first obtained based on the total station, and an existing coordinate system based on the total station and a new coordinate system based on the intelligent fine-tuning vehicle are established respectively. The moving and static point coordinates and initial lengths of the three groups of vertical electric cylinders and three groups of horizontal electric cylinders of the fine-tuning vehicle under the initial position conditions are obtained, and the spatial coordinates of the fine-tuning vehicle and the track plate and the angle between the new coordinate system and the existing coordinate system are calculated.
[0023] The spatial position coordinate data of the fine-tuning vehicle and the track plate based on the CPIII control network are obtained by the total station. Among them, the coordinate data of the three prisms of the fine-tuning vehicle are: the center coordinate of the left prism A (X a , Y a , Z a ), right prism center coordinate B (X b , Y b , Z b )、the center coordinate of the rear prism C(X c , Y c , Z c), the coordinate data of the four prisms on the track plate are: 1# prism coordinates (X1, Y1, Z1), 2# prism coordinates: 2#X2, Y2, Z2), 5# prism coordinates: 5# (X5, Y5, Z5), 6# prism coordinates: 6# (X6, Y6, Z6). The schematic diagram of the total station and the position of each measuring point is as follows Figure 2 shown.
[0024] In addition, in order to facilitate the calculation of relevant parameters during the track slab fine-tuning process, it is necessary to define the signs of the slab laying direction, elevation adjustment amount, and lateral adjustment amount. Among them, adjusting the slab in the direction of increasing mileage is "+", and adjusting the slab in the direction of decreasing mileage is "-"; increasing elevation is "+", and decreasing elevation is "-"; using the total station as the reference to observe the rearview prism in the direction of increasing mileage, adjusting to the left of the track slab centerline is "+", and adjusting to the right of the track slab centerline is "-", such as Figure 3 shown.
[0025] During the fine-tuning construction process, a coordinate system based on the total station is involved, which the present invention refers to as the existing coordinate system, and a coordinate system based on the intelligent fine-tuning vehicle is involved, which the present invention refers to as the new coordinate system.
[0026] For the existing coordinate system, the longitudinal direction of the line is the Y-axis, the direction from the total station to the rearview prism is the positive direction of the Y-axis, the transverse direction of the line is the X-axis, the right direction is the positive direction of the X-axis, the vertical direction of the line is the Z-axis, the vertical upward direction is the positive direction of the Z-axis, the coordinate origin is O (0, 0, 0), and the coordinate position of any point in space in this coordinate system is P (X, Y, Z).
[0027] For a new coordinate system, such as Figure 4 As shown, the longitudinal centerline of the fine-tuning vehicle is the Y' axis, the longitudinal centerline of the fine-tuning vehicle frame is consistent with the positive direction of the Y axis of the total station, the transverse centerline of the fine-tuning vehicle is the X' axis, the right is the positive direction of the X' axis (consistent with the direction of the X coordinate axis of the total station), the vertical direction of the fine-tuning vehicle is the Z' axis, the vertical upward is the positive direction of the Z' axis (consistent with the direction of the Z axis of the total station), the coordinate origin is O'(0, 0, 0), and the coordinate position of any point in the space in this coordinate system is P'(X', Y', Z').
[0028] Assume that the spatial position of the origin O' of the new coordinate system in the existing coordinate system is O'(X0, Y0, Z0), and the angle relationship between the coordinate axes X', Y', Z' of the new coordinate system and the coordinate axes X, Y, Z of the existing coordinate system is shown in Table 1.
[0029] Table 1 Angles between the new coordinate system and the existing coordinate system The transformation formula between the new coordinate system and the existing coordinate system is: The inverse transform formula is: The fine-tuning car consists of multiple structures. Among them, three sets of horizontal electric cylinders and three sets of vertical electric cylinders directly control the spatial position of the track plate. It is necessary to know the coordinates of each electric cylinder in the horizontal and vertical directions. Combined with the relative position of the fine-tuning car structure and the track plate, when the longitudinal centerline of the fine-tuning car and the track plate coincide, the coordinates and lengths of the fixed points of the three sets of horizontal electric cylinders are as follows: No. 1 horizontal electric cylinder: Moving point coordinates: M1 (X' M1 ,0,Z' M1 ), that is, M1 (0, 0, -2145) Fixed point coordinates: N1 (-770, 0, 2909.4) Cylinder length: L1=1085±200 No. 2 horizontal electric cylinder: Moving point coordinates: M2 (X' M2 ,0,Z' M2 ), that is, M2 (0, 0, -2145) Fixed point coordinates: N2 (770, 0, 2909.4) Electric cylinder length: L2=1085±200 No. 3 horizontal electric cylinder: Moving point coordinates: M3 (X' M3 ,0,Z' M3 ), that is, M3 (0, 0, 2145) Fixed point coordinates: N3 (1236, 0, 2145) Electric cylinder length: L3=1235±250 Similarly, when the fine-tuning trolley is parallel to the plane of the fine-tuning vehicle frame, the coordinates and lengths of the moving points of the three sets of vertical electric cylinders are: No. 4 vertical electric cylinder: Moving point coordinates: M4 (621, Y' M4 , 1514), that is, M1 (621, -200, 1514) Fixed point coordinates: N4 (621, 612, 1514) Electric cylinder length: L4=895±175 No. 5 vertical electric cylinder: Moving point coordinates: M5 (-621, Y' M5, 1514), that is, M5 (-621, -200, 1514) Fixed point coordinates: N5 (-621, 612, 1514) Electric cylinder length: L5=895±175 No. 6 vertical electric cylinder: Moving point coordinates: M6 (0, Y' M6 , -1514), that is, M6 (0, -200, 1514) Fixed point coordinates: N6 (0, 612, 1514) Electric cylinder length: L6=895±175 Furthermore, when the longitudinal center lines of the fine-tuning car and the track plate coincide with each other and the fine-tuning car is parallel to the plane of the fine-tuning car frame, the lengths of the universal joint sleeve and the universal joint seat in the fine-tuning car are: Universal joint sleeve center distance length: L7=L8=L9=225 Length from the center of the universal joint to the flange surface: L 10 =L 11 =L 12 =85 After establishing a spatial coordinate system based on the total station and the fine-tuning vehicle, and clarifying the spatial coordinates of key locations on the track slab and the fine-tuning vehicle, a mathematical model for track slab fine-tuning must be constructed. First, the coordinate data of the three prisms measured on the fine-tuning vehicle must be converted to the new coordinate system, and the coordinate origin of the fine-tuning vehicle must be calculated.
[0030] Calculating the coordinate data of the left prism yields: Calculating the coordinate data of the right prism yields: After calculating the coordinate data of the rear prism, we can get: Then the coordinate origin of the fine-tuning vehicle can be obtained as: Furthermore, the angle between the new coordinate system and the existing coordinate system can be obtained as: Based on the angles between the coordinate systems, the coordinates of the four prisms of the track slab after rough paving can be calculated as: S102 . In the new coordinate system, first extension and contraction amounts of three groups of horizontal electric cylinders of the fine-tuning vehicle are calculated based on preset target positions.
[0031] Specifically, the initial coordinates of the moving point and the fixed point of the horizontal electric cylinder in the new coordinate system can be obtained; the target coordinates of the moving point are determined according to the preset target position; and the target electric cylinder length is calculated as the first extension amount based on the target coordinates of the moving point and the fixed point.
[0032] After the spatial coordinates of the fine-tuning vehicle and the track plate and the angle between the new coordinate system and the existing coordinate system are determined, the calculation of the track plate fine-tuning process can be started to complete the high-precision adjustment of the track plate. First, adjust the horizontal direction. When the horizontal adjustment bracket of the fine-tuning vehicle coincides with the new coordinate system, the following mathematical relationship exists in the XY plane:
[0033] No. 1 horizontal electric cylinder: Moving point coordinates: M 1x (L0 / 2, 0), fixed point coordinates: N 1x (X'N1, Y'N1), cylinder length: .
[0034] No. 2 horizontal electric cylinder: Moving point coordinates: M 2x (L0 / 2, 0), fixed point coordinates: N 2x (X'N2, Y'N2), cylinder length: .
[0035] No. 3 horizontal electric cylinder: Moving point coordinates: M 3x (L0 / 2, 0), fixed point coordinates: N 3x (X'N3, Y'N3), cylinder length: .
[0036] Among them, L0 is the center distance between the two moving points, 4290mm, L1=L2=1080mm, L3=1235mm.
[0037] On this basis, the center C of the horizontal traverse bracket can be obtained VJ The spatial coordinates and deflection angle θ1: Then Figure 5 As shown, the coordinates of the moving points M1, M2, and M3 are: Among them, according to the right-hand rule, θ1 rotates counterclockwise as positive and clockwise as negative. From this, the lengths of the three sets of horizontal electric cylinders after fine adjustment can be calculated: By calculating the difference in length of the electric cylinder before and after fine-tuning, the extension and contraction amounts of the three groups of horizontal electric cylinders can be obtained.
[0038] S103. Establish a temporary coordinate system based on the center of the track plate, convert the center coordinates of the vertical fine-tuning bracket of the fine-tuning vehicle from the new coordinate system to the temporary coordinate system, and determine the coordinates of the moving and static points of the vertical electric cylinder of the fine-tuning vehicle in the temporary coordinate system based on the conversion result.
[0039] With the center coordinates of the track plate O”(X, Y, Z”) as the origin, a temporary coordinate system is established, such as Figure 6 shown.
[0040] Specifically, the first direction angle between the new coordinate system and the temporary coordinate system may be calculated; and the center coordinates of the vertical fine-tuning bracket may be converted from the new coordinate system to the temporary coordinate system using the first direction angle.
[0041] In this step, it is necessary to clarify the reference of each coordinate system, the conversion method of each coordinate system, and the angle of each coordinate system. First, the relative position between the fine-tuning vehicle and the track plate needs to be calculated. The specific process is as follows:
[0042] Calculate the center coordinates of the track plate using the coordinates of the four prisms on the track plate. This step takes prisms No. 1 and No. 5 as examples. To facilitate calculation, it is necessary to clarify the eigenvectors in each direction of the temporary coordinate system, where: The length of the eigenvector of the direction is half the distance between point 1 and point 2, and is parallel to the line connecting point 1 and point 2. The spatial coordinates of point 7 are: The eigenvector of the direction passes through the origin of the temporary coordinate system , the direction is perpendicular to the line connecting points 1 and 2, and the length is the distance between the origin of the temporary coordinate system and the line connecting points 1 and 2. Then the spatial coordinates of point 8 can be calculated: in, , , , The eigenvector of the direction passes through the origin of the temporary coordinate system , and with 、 The directional eigenvectors are perpendicular, so the spatial coordinates of point 9 are: .
[0043] in, , , , , , , , , , , .
[0044] Furthermore, the angle between the temporary coordinate system and the new coordinate system before the track slab fine-tuning construction can be obtained, as shown in Table 2: Table 2 Angle between the temporary coordinate system and the new coordinate system After clarifying the angle between the temporary coordinate system and the new coordinate system, it is required to obtain the spatial coordinate C' of the center of the vertical fine-tuning bracket of the fine-tuning vehicle in the new coordinate system HJ1 ,like Figure 7 shown.
[0045] Assume that the height from the support surface of the track plate support device to the track plate prism is H B1 Since the track plate and the vertical fine-tuning frame of the fine-tuning vehicle are not horizontal during the fine-tuning construction process, when the fine-tuning vehicle's gripping mechanism is facing the track plate support structure, it can be assumed that the vertical fine-tuning frame is parallel to the track plate, that is, the center of the vertical fine-tuning frame coincides with the center of the track plate, with a height difference of only H. J , let the height from the track plate prism plane to the support structure plane be H B1 , the distance from the center plane of the concave ball of the vertical fine-tuning bracket to the plane of the grab plate mechanism is HZ, then H J =H Z -H B1 Therefore, the structural center point of the vertical fine-tuning bracket is used as the midpoint for finding the alignment, which is recorded as C' HJ1 , its position in the temporary coordinate system is C" HJ1 (0, 0, H J ). Then C' can be calculated HJ1 Spatial position in the temporary coordinate system:
[0046] Fine-tune the bracket center C' vertically HJ1 As the coordinate origin, the ball head C' of the No. 4 vertical electric cylinder can be obtained G41 The spatial coordinates of: Similarly, the ball head C' of the No. 5 and No. 6 vertical electric cylinders can be obtained. G51 and C' G61 The spatial coordinates of: S104. Adjust the track plate in the horizontal direction based on the first expansion and contraction amount; convert the coordinates of the moving and static points of the vertical electric cylinder to a new coordinate system, calculate the second expansion and contraction amount of the vertical electric cylinder based on the preset target position in the new coordinate system, and adjust the track plate in the vertical direction based on the second expansion and contraction amount.
[0047] Specifically, based on the first extension and contraction amount, the horizontal electric cylinder is driven to adjust the track plate to the preset target position in the horizontal direction; a temporary new coordinate system centered on the preset target position is established, and the moving and static point coordinates of the vertical electric cylinder are converted from the temporary coordinate system to the temporary new coordinate system, and then converted to the new coordinate system. In the new coordinate system, the second extension and contraction amount of the vertical electric cylinder is calculated based on the preset target position, and based on the second extension and contraction amount, the vertical electric cylinder is driven to adjust the track plate to the preset target position in the vertical direction.
[0048] In this step, first, the horizontal electric cylinder is controlled to control the fine-tuning vehicle bracket according to the horizontal expansion and contraction amount, so that the track plate can reach the fine-tuning position on the vertical projection surface; secondly, after the track plate is adjusted to reach the target position in the horizontal direction, due to the change in the position of the track plate, in order to accurately calculate the second expansion and contraction amount of the vertical electric cylinder, this step establishes a temporary new coordinate system with the preset target position as the center as a transfer, and converts the dynamic and static points of the vertical electric cylinder to the new coordinate system. Specifically, the second direction angle between the temporary coordinate system and the temporary new coordinate system, as well as the third direction angle between the temporary new coordinate system and the new coordinate system, are calculated; the coordinates of the dynamic and static points of the vertical electric cylinder are converted from the temporary coordinate system to the temporary new coordinate system through the second direction angle, and then converted to the new coordinate system through the third direction angle; the second expansion and contraction amount is calculated based on the converted coordinates of the dynamic and static points of the vertical electric cylinder. The specific calculation method is the same as the first expansion and contraction amount, and will not be repeated here.
[0049] In one embodiment, by controlling the coordinated operation of various mechanisms in the fine-tuning vehicle, the track plate can be adjusted from the initial position to the preset target position, and the spatial coordinates of each prism on the track plate after fine-tuning are: 1# prism coordinates: 1#' (X1', Y1', Z1'), 2# prism coordinates: 2#' (X2', Y2', Z2'), 5# prism coordinates: 5#' (X5', Y5', Z5'), 6# prism coordinates: 6#' (X6', Y6', Z6').
[0050] Through total station re-measurement and calculation and analysis by layout software, the actual coordinates of the adjusted trackbed plate are compared with the theoretical coordinates. If they are within the tolerance range of the construction specifications, the fine adjustment is considered to be in place and qualified. Otherwise, a second fine adjustment is required until it is qualified.
[0051] Specifically, after completing the horizontal position fine adjustment, it is necessary to further adjust the three groups of vertical electric cylinders, such as Figure 8 As shown, first of all, it is necessary to clarify the motion range of the fine-tuning car structure, among which the angle between the longitudinal direction of the track plate and the horizontal plane does not exceed 4°, and the angle between the transverse direction of the track plate and the horizontal plane does not exceed 7°. The minimum length of the three groups of vertical electric cylinders is 715mm, the stroke is 360mm, and the maximum length is 1075mm. Therefore, the movement of the three groups of electric cylinders is subject to the following restrictions: the length difference between the No. 4 vertical electric cylinder and the No. 5 vertical electric cylinder should be less than 216mm; the length difference between the No. 4 vertical electric cylinder and the No. 6 vertical electric cylinder should be less than 216mm; the length difference between the No. 5 vertical electric cylinder and the No. 6 vertical electric cylinder should be less than 150mm. In addition, the extension direction of the electric cylinder is positive, and the contraction direction of the electric cylinder is negative.
[0052] When the three sets of vertical electric cylinders are at any length and waiting for the fine adjustment mechanism to grab the track plate (the plate grabbing mechanism should be 30~50mm higher than the support device), the grabbing and extension amount of the vertical electric cylinders can be calculated. At this time, the lengths of the three sets of electric cylinders are L 4x 、L 5x 、L 6x , then the vertical coordinates of each moving point are: First, adjust the vertical fine-tuning bracket to be parallel to the track plate, then: in: , When the vertical fine-tuning bracket is parallel to the track plate, the three sets of vertical electric cylinders extend simultaneously to complete the track plate grabbing action. Further, the spatial position of the track plate must be adjusted by six sets of electric cylinders. First, the initial length values of the three horizontal electric cylinders and the three vertical electric cylinders before the fine-tuning construction must be recorded. Among them, the three sets of horizontal electric cylinders are not in motion, and the three sets of vertical electric cylinders remain at the retracted length of the electric cylinders. At this time, the spatial coordinates of the vertical electric cylinder moving points in the new coordinate system are: C' G42 (X' CG41 , Y' CG41 , Z' CG42 )、C' G52 (X' CG51 , Y' CG51 , Z' CG52 )、C' G62 (X' CG61 , Y' CG61 , Z' CG62 ), the angle between each point is ∠C G5 C G4 C HJ =θ=tan -1 (621 / 3028). On this basis, the ball head coordinates of each vertical fine-tuning bracket can be calculated separately:
[0053] in: , , Furthermore, the vertical fine-tuning bracket C' can be calculatedG42 Point, C' G520 Point and C' G620 The spatial position of a point in an existing coordinate system: During the fine-tuning construction process, the spatial position of the track plate changes from the initial position to the laying position. During this process, the C' on the vertical fine-tuning bracket G42 Point, C' G520 Point and C' G620 The relationship between the point and the existing coordinate system remains unchanged, so a temporary new coordinate system of the track plate prism after fine-tuning construction can be established, and the angle between the temporary new coordinate system and the fine-tuning vehicle frame coordinate system can be calculated, as shown in Table 3.
[0054] Table 3 Angle between the temporary new coordinate system and the new coordinate system Furthermore, C' G42 Point, C' G520 Point and C' G620 The spatial position of the point is converted into the spatial coordinates in the fine-tuning vehicle frame coordinate system (new coordinate system): After determining the spatial coordinates of the track plates before and after fine-tuning, the expansion and contraction changes of the six electric cylinders during fine-tuning can be calculated. For the three vertical electric cylinders, the distance between the final position and the initial position after fine-tuning can be directly calculated: For three sets of horizontal electric cylinders, first of all, C G73 、C HJ30The coordinates and C HJ30 、C G43 The angle θ9 between the line connecting the two points and the X-axis of the fine-tuning lathe frame is θ9.
[0055] Next, we need to get the coordinates of each moving point of the horizontal electric cylinder. To facilitate understanding, a schematic diagram of the extension and contraction of the horizontal electric cylinder during fine adjustment is drawn, as shown below: Figure 9 shown.
[0056] After fine-tuning, the lengths of the three groups of horizontal electric cylinders are: Considering that other actions of the three groups of horizontal electric cylinders before fine-tuning may cause the length of the electric cylinder to change, it is assumed that the change of each group of electric cylinders is ΔL 12 , ΔL 22 , ΔL 32 , the extension and contraction amounts of the three groups of horizontal electric cylinders during fine adjustment are: At this point, the expansion and contraction data of the six groups of electric cylinders during the fine-tuning construction process have been calculated. After adopting this method, the fine-tuning vehicle controls the length of the horizontal and vertical electric cylinders, uses the clamps to clamp the track plate, and adjusts the track plate to the designed position. During the adjustment process, the mechanical state of the track structure and construction equipment must be paid special attention.
[0057] This method uses a total station to obtain the coordinates of the fine-tuning vehicle's prism and establish a new coordinate system. Combined with the coordinated control of horizontal and vertical electric cylinders, it achieves precision and automation in the track plate fine-tuning process. Compared with traditional adjustment methods, this method first accurately calculates the electric cylinder's expansion and contraction through dynamic coordinate system conversion, allowing the track plate to be positioned to the preset position in one go. This completely solves the problem of traditional methods where input deviations cause the track plate to press against adjacent plates, requiring repeated plate withdrawal and readjustment. This significantly improves construction efficiency and avoids the shortcomings of traditional methods of repeated adjustments relying on experience, making the entire fine-tuning process more scientific and efficient. Therefore, this method excels in improving fine-tuning accuracy, reducing the number of adjustments, optimizing the adjustment process, and improving construction efficiency, providing strong technical support for high-speed railway ballastless track construction.
[0058] Secondly, the present invention also provides a track plate position adjustment device, such as Figure 10 As shown, including: The measurement module 1001 is used to obtain the coordinates of the fine-tuning vehicle and the track plate through a total station, and to establish a new coordinate system based on the fine-tuning vehicle.
[0059] The calculation module 1002 is used to calculate the first extension and contraction amounts of the three groups of horizontal electric cylinders of the fine-tuning vehicle based on the preset target positions in the new coordinate system.
[0060] The conversion module 1003 is used to establish a temporary coordinate system based on the center of the track plate, convert the center coordinates of the vertical fine-tuning bracket of the fine-tuning vehicle from the new coordinate system to the temporary coordinate system, and determine the coordinates of the moving and static points of the vertical electric cylinder of the fine-tuning vehicle in the temporary coordinate system based on the conversion results.
[0061] The fine-tuning module 1004 is used to drive the horizontal electric cylinder to adjust the track plate to a preset target position in the horizontal direction based on the first extension amount; establish a temporary new coordinate system centered on the preset target position, convert the moving and static point coordinates of the vertical electric cylinder from the temporary coordinate system to the temporary new coordinate system, and then convert it to the new coordinate system, calculate the second extension amount of the vertical electric cylinder based on the preset target position in the new coordinate system, and drive the vertical electric cylinder to adjust the track plate to the preset target position in the vertical direction based on the second extension amount.
[0062] By using the above-mentioned device, the coordinates of the fine-tuning vehicle prism are obtained through a total station and a new coordinate system is established. Combined with the coordinated control of the horizontal / vertical electric cylinder, the track plate fine-tuning process is made precise and automated. Compared with the traditional adjustment method, the dynamic coordinate system conversion is first used to accurately calculate the extension and contraction of the electric cylinder, and the track plate can be positioned to the preset position in one go. This completely solves the problem of the traditional method where the track plate is pressed against the adjacent plate due to input deviation and needs to be repeatedly withdrawn and readjusted. It significantly improves construction efficiency and avoids the shortcomings of the traditional method of relying on experience for repeated adjustments, making the entire fine-tuning process more scientific and efficient. Therefore, this method performs well in improving fine-tuning accuracy, reducing the number of adjustments, optimizing the adjustment process, and improving construction efficiency, providing strong technical support for the construction of high-speed railway ballastless tracks.
