Description

Technical Field

[0001] This invention relates to the field of ballastless track construction technology, specifically to an adjustment method for a double-block ballastless track fine-tuning power track panel. Background Technology

[0002] Due to its advantages such as good stability, long service life, and low maintenance workload, twin-block ballastless track is widely used in rail transit projects such as high-speed railways and intercity railways. Track panel fine-tuning is the core process in the construction of twin-block ballastless track. Its fine-tuning accuracy directly determines the smoothness, comfort, and safety of the track, and thus affects the stability and service life of train operation.

[0003] Currently, existing double-block ballastless track panel fine-tuning technology still faces numerous technical challenges, making it difficult to meet the precision and efficiency requirements of high-standard track construction. Firstly, existing fine-tuning equipment mostly employs manual or semi-manual adjustment methods. During the adjustment process, operators must repeatedly measure and adjust, resulting in high labor intensity, low construction efficiency, and poor consistency due to human error, leading to insufficient precision and difficulty in controlling track elevation, slope, and lateral position deviations within preset ranges. Secondly, the existing fine-tuning systems have low integration of adjustment components; height, lateral, and angle adjustments are independent, easily causing interference during adjustment and preventing multi-dimensional coordinated adjustment. This results in poor overall track panel smoothness, especially during long-distance continuous track panel construction, where significant connection deviations between adjacent track panels affect the overall track quality. Third, existing detection units are mostly fixed or manually moved, resulting in limited detection range and low efficiency. They cannot achieve real-time dynamic detection during track panel fine-tuning, and the detection data is not synchronized with the adjustment actions, easily leading to repeated cycles of "detection-adjustment-re-detection," further reducing construction efficiency. Simultaneously, the detection data lacks effective location correlation methods, requiring additional manpower to verify locations during subsequent data processing and defect localization, increasing the workload. Fourth, existing fine-tuning drive components lack effective torque protection mechanisms. If obstacles are encountered during adjustment or excessive adjustment resistance occurs, the drive components are prone to overload damage, or forced adjustment can cause deformation of the track panel structure, affecting construction safety and equipment lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustment method for a dual-block ballastless track fine-tuning power track panel. This method can solve the technical problems of insufficient track panel fine-tuning accuracy, low construction efficiency, high labor intensity, poor adjustment coordination, and inconvenient testing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A method for adjusting a double-block ballastless track fine-tuning power track panel includes several main beams sequentially arranged on two tracks. A fine-tuning unit is set at each end of the main beams. Each fine-tuning unit includes a support leg body, a height adjustment component, a height drive component, an angle adjustment component, a lateral adjustment component, and a lateral drive component. The height drive component is located within the height adjustment component, and the support leg body is located at the bottom of the height adjustment component. The height drive component is used to adjust the height of the support leg body relative to the height adjustment component. One end of the angle adjustment component is located on the height adjustment component, and the lateral adjustment component is located at the other end of the angle adjustment component. The angle adjustment component is used to adjust the installation angle of the lateral adjustment component. The lateral drive component is located within the angle adjustment component. A detection unit is set on the tracks. The detection unit includes a traction trolley and a measuring component. The traction trolley pulls the measuring component to move on the two tracks, and the measuring component is used to measure the slope and relative height difference between the two tracks. The adjustment method includes the following steps: Step 1, track laying: Place several track panel groups in the designated positions. Each track panel has four main beams, and each main beam has a fine-tuning unit installed at both ends. Step two, preliminary adjustment: The lateral movement of the main beam is adjusted by the lateral adjustment component and the lateral drive component to adjust the track laying direction; the height of the track is adjusted by the height adjustment component and the height drive component at both ends of the main beam. Step 3, fine-tuning: The detection unit detects the slope and relative height difference of the two tracks after the initial adjustment, and sends the detection information to the control center. The control center controls different lateral drive components and height drive components to operate based on the error between the slope and height difference and the preset value. Step four, overall measurement: After the specified number of track panels have been fine-tuned, the detection unit moves from one end of the completed track panel to the other and sends the overall measurement information to the control center. The control center controls different lateral drive components and height drive components to operate according to the error between the slope and height difference and the preset value.

[0006] Preferably, in step four, when the driving torque of the lateral drive component and / or the height drive component exceeds the threshold during adjustment, the corresponding lateral drive component and / or height drive component stops adjusting, while other positions continue to be adjusted; when the driving torque is less than the threshold, adjustment continues.

[0007] Preferably, multiple identification plates are spaced apart on the inner side of the track, and the identification plates are provided with QR codes, barcodes or digital labels for recording location information; a detection component is provided on the side of the traction trolley or the measuring component, and the detection component is used to identify different labels on the identification plates.

[0008] Preferably, the height adjustment assembly includes a support plate, a vertical sliding sleeve, a vertical nut, and a vertical slider. The vertical sliding sleeve is fixedly disposed at the bottom of the support plate, the vertical nut is fixedly disposed on the vertical slider, the vertical slider is slidably disposed within the vertical sliding sleeve, and the height driving assembly is poweredly connected to the vertical nut.

[0009] Preferably, the height driving assembly includes a vertical drive motor, a first reducer, and a vertical adjusting screw. The vertical drive motor is fixedly mounted on the support plate, the first reducer is fixedly mounted on the vertical drive motor, the vertical adjusting screw is poweredly connected to the output end of the first reducer, and the vertical adjusting screw is poweredly connected to the vertical nut.

[0010] Preferably, the support leg body includes a support base and a heightening section, the heightening section being detachably mounted on the bottom of the vertical slider, and the support base being hinged to the bottom of the heightening section.

[0011] Preferably, the lateral adjustment component includes a support sleeve, a lateral nut, and a lateral slider. One end of the support sleeve is movably disposed on the angle adjustment component, the lateral slider is slidably disposed inside the support sleeve, the lateral nut is fixedly disposed on the lateral slider, and the lateral nut is poweredly connected to the lateral drive component.

[0012] Preferably, the angle adjustment assembly includes a first support, a second support, an angle adjustment screw, and a hinge rod. The first support is fixedly disposed on one side of the height adjustment assembly, and the angle adjustment screw is movably mounted on the first support and connected to the support sleeve by a thread. The second support is fixedly disposed on the other side of the height adjustment assembly, and the support sleeve is hinged to the second support by the hinge rod.

[0013] Preferably, the lateral drive assembly includes a lateral drive motor, a second reducer, and a lateral adjusting screw. The lateral drive motor is fixedly mounted on the support sleeve, the second reducer is fixedly mounted on the lateral drive motor, the lateral adjusting screw is poweredly connected to the output end of the second reducer, and the lateral adjusting screw is poweredly connected to the lateral nut.

[0014] Preferably, a swing indicator needle is fixedly installed on the support sleeve, and a dial is installed on the height adjustment component.

[0015] In this invention, by setting up height drive components and lateral drive components in conjunction with the control center, the elevation and lateral position of the track panel can be automatically adjusted, eliminating the need for repeated manual adjustments by operators and significantly reducing labor intensity. At the same time, the drive components use servo motors with reducers, resulting in higher adjustment accuracy and better consistency. Combined with real-time feedback from the detection unit, the control center can precisely control the actions of each drive component based on the error amount, effectively avoiding human error and ensuring that the deviations in track elevation, slope, and lateral position are controlled within the preset range, significantly improving the fine-tuning accuracy of the track panel.

[0016] The height adjustment component, lateral adjustment component, and angle adjustment component are integrated into the same fine-tuning unit to achieve multi-dimensional coordinated adjustment of height, lateral, and angle, avoiding interference between the adjustment actions. At the same time, the "double rail, four beams, eight legs" structure ensures uniform stress on the track panel and better track panel stability during adjustment. Especially when constructing long-distance track panels continuously, it can effectively reduce the connection deviation between adjacent track panels, ensure the overall smoothness of the track, and improve the quality of track construction.

[0017] The detection unit uses a traction trolley to move the measurement components, enabling real-time dynamic detection during track panel fine-tuning. Detection data is sent to the control center in real time, achieving simultaneous "detection-adjustment" and avoiding repeated cyclical detection and adjustment, significantly improving construction efficiency. Simultaneously, markers with location information are installed on the inner side of the track. The detection components can automatically identify the marker information, associating and storing the detection data with the location information. Subsequent data processing and defect location do not require additional location verification, reducing construction workload and improving the accuracy of data retrieval and defect location.

[0018] Both the height drive component and the lateral drive component are equipped with torque sensors. When the adjusted drive torque exceeds the threshold, the corresponding drive component automatically stops adjusting, while other components continue to adjust. This avoids overload damage to the drive components and prevents deformation of the track structure caused by forced adjustment. When the drive torque returns to below the threshold, the drive components continue to work, ensuring construction safety and extending the service life of the equipment.

[0019] The outrigger body is equipped with a detachable extension section, which can be flexibly replaced with extension sections of different heights according to different track installation heights, making it more adaptable; the support base is hinged at the bottom of the extension section, which can accommodate minor displacement during lateral adjustment and improve the fit between the outrigger and the support surface; at the same time, an external support is set on one side of the vertical slider, which can be connected to the positioner to prevent the fine adjustment system from sliding laterally and further improve the stability of the fine adjustment accuracy.

[0020] The angle adjustment component can drive the support sleeve to swing around the hinge rod by rotating the angle adjustment screw, so as to achieve precise adjustment of the installation angle of the lateral adjustment component. At the same time, the support sleeve is equipped with a swing indicator needle, and the height adjustment component is equipped with a scale, which can realize the digital display of the angle adjustment, so that the operator can accurately control the adjustment angle, further improve the accuracy of the track slope adjustment, and ensure that the track slope meets the design requirements.

[0022] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 7The present invention discloses an adjustment method for a double-block ballastless track fine-tuning power track panel. The fine-tuning system includes two parallel tracks 100 and several main beams 101 arranged sequentially on the two tracks 100. In this embodiment, the construction length of a single track 100 is 6.5m, and four main beams 101 are set in each track panel, presenting a structure of double track, four beams, and eight legs.

[0023] A fine-tuning unit is set at each end of the main beam 101. The fine-tuning unit is used to adjust the installation height, laying direction, horizontal position, slope and tilt angle of the track 100.

[0024] The fine-tuning unit includes a leg body 1, a height adjustment component 2, a height drive component 3, an angle adjustment component 4, a lateral adjustment component 5, and a lateral drive component 6.

The height driving assembly 3 is poweredly connected to the vertical screw nut 22 and drives the vertical slider 23 to slide vertically along the vertical sliding sleeve 21.

[0026] The height drive assembly 3 is disposed within the height adjustment assembly 2, and is used to adjust the height of the outrigger body 1 relative to the height adjustment assembly 2.

[0027] The vertical drive motor 30 is a servo motor, which is controlled by the operator via a driver and servo controller to rotate and stop. When the vertical drive motor 30 rotates, the first reducer 31 reduces speed and increases torque, driving the vertical adjusting screw 32 to rotate. The power is then transmitted through the vertical nut 22, causing the vertical slider 23 to slide vertically along the vertical sleeve 21. The vertical drive motor 30 is equipped with a torque sensor.

[0028] The housing 12 is detachably mounted on the support plate 20 by fasteners. The vertical drive motor 30 and the first reducer 31 are both located inside the housing 12, which provides a safety protection effect.

[0029] Multiple external support members 13 are provided on one side of the vertical slider 23. A slot is provided on the vertical sleeve 21 at the position corresponding to the external support member 13. When the vertical slider 23 slides vertically along the vertical sleeve 21, the slot provides movement space for the external support member 13. The external support member 15 is used to connect with the positioner to prevent lateral slippage of the system.

[0030] The outrigger body 1 is located at the bottom of the height adjustment assembly 2. The outrigger body 1 includes a support base 10 and an extender section 11. The extender section 11 is detachably mounted on the bottom of the vertical slider 23, and the support base 10 is hinged to the bottom of the extender section 11. The extender section 11 is used to increase the overall height to accommodate the installation height of the track 100. Extender sections 11 of different heights are installed according to different height differences. The support base 10 is hinged to the bottom of the extender section 11 via a pin to accommodate small displacements during lateral adjustment.

[0031] Angle adjustment component 4 is mounted on height adjustment component 2 at one end, and is used to adjust the installation angle of lateral adjustment component 5. Angle adjustment component 4 includes a first support 40, a second support 41, an angle adjustment screw 42, and a hinge rod 43. The first support 40 is fixedly mounted on one side of height adjustment component 2, and the angle adjustment screw 42 is movably mounted on the first support 40 and connected to support sleeve 50 by threads. The second support 41 is fixedly mounted on the other side of height adjustment component 2, and support sleeve 50 is hinged to the second support 41 by hinge rod 43.

[0032] Specifically, the first support 40 is fixedly installed on one side of the vertical sliding sleeve 21. A waist-shaped groove is provided on the first support 40, and the angle adjusting screw 42 is slidably installed in the waist-shaped groove. A connecting shaft is rotatably installed on the support sleeve 50, and a threaded hole is provided on the connecting shaft. The angle adjusting screw 42 is connected in the threaded hole. The waist-shaped groove and the rotatably installed connecting shaft are used to accommodate the swing of the support sleeve 50.

[0033] The second support 41 is fixedly mounted on the other side of the vertical sliding sleeve 21. When the angle adjustment screw 42 is rotated, the support sleeve 50 swings around the hinge rod 43 to achieve angle adjustment. An adjustment hole is provided on the second support 41. After the angle of the support sleeve 50 is adjusted, the clamping rod passes through the adjustment hole to fix the support sleeve 50 to the side of the second support 41, thereby achieving a tight connection of the support sleeve 50.

[0034] A swing indicator 44 is fixedly mounted on the support sleeve 50, and a scale 45 is mounted on the height adjustment assembly 2. The scale 45 is mounted on the vertical sliding sleeve 21. When the support sleeve 50 rotates, the swing indicator 44 rotates accordingly, and the swing indicator 44 indicates different scales on the scale 45, realizing digital display of angle adjustment.

[0035] The lateral adjustment component 5 is located at the other end of the angle adjustment component 4. The lateral adjustment component 5 includes a support sleeve 50, a lateral nut 51, and a lateral slider 52. One end of the support sleeve 50 is movably mounted on the angle adjustment component 4. The lateral slider 52 is slidably mounted inside the support sleeve 50. The lateral nut 51 is fixedly mounted on the lateral slider 52. The lateral nut 51 is poweredly connected to the lateral drive component 6.

[0036] The lateral drive assembly 6 is installed inside the angle adjustment assembly 4. The lateral drive assembly 6 includes a lateral drive motor 60, a second reducer 61, and a lateral adjustment screw 62. The lateral drive motor 60 is fixedly installed on the support sleeve 50, the second reducer 61 is fixedly installed on the lateral drive motor 60, the lateral adjustment screw 62 is poweredly connected to the output end of the second reducer 61, and the lateral adjustment screw 62 is poweredly connected to the lateral nut 51.

[0037] The lateral drive motor 60 is a servo motor, which is controlled by the operator via a driver and servo controller to rotate and stop. When the lateral drive motor 60 rotates, the second reducer 61 reduces speed and increases torque, driving the lateral adjusting screw 62 to rotate. The power is then transmitted through the lateral nut 51, causing the lateral slider 52 to slide laterally along the support sleeve 50. The lateral drive motor 60 is equipped with a torque sensor.

[0038] The housing is detachably mounted on the support sleeve 50 by fasteners. The transverse drive motor 60 and the second reducer 61 are both located inside the housing, which provides a safety protection effect.

[0039] The fine-tuning system also includes a control unit 9, which controls the individual or coordinated operation of multiple height drive components 3 and lateral drive components 6 in each track panel. The control unit 9 is a PLC programmable controller with a built-in control program, and each height drive component 3 and lateral drive component 6 performs corresponding actions according to the program and position detection information.

[0040] A detection unit is set on the track 100. The detection unit includes a traction trolley 7 and a measuring component 8. The traction trolley 7 pulls the measuring component 8 to move on the two tracks 100. The measuring component 8 is used to measure the slope and relative height difference of the two tracks 100.

[0041] The tractor 7 includes a frame body 70, wheels 71, a traction drive assembly 72, a tow bar 73, and a battery pack 74. The frame body 70 includes a lower housing and one or more upper housings detachably mounted on the lower housing. In this embodiment, the lower housing is divided into two areas. One area houses the battery pack 74, which powers the tractor 7, providing appropriate power to each electrical component and part. When the upper housing is closed, the battery pack 74 is housed within the frame body 70. The other area houses the controller 75, remote control receiver, wireless module, etc., and is arranged separately from the battery pack 74. Its heat dissipation does not affect the battery pack 74, and it allows the center of gravity to be adjusted to a neutral position. The battery pack 74 is a lithium battery or a lead-acid battery.

[0042] A display 76 is detachably mounted on the top of the chassis body 70 via fasteners. A controller 75 is installed inside the chassis body 70. The display 76 is electrically connected to the controller 75. The display 76 is used to display information such as vehicle driving status, location information, and driving speed. The controller 75 is a microcontroller or PLC programmable controller.

[0043] Multiple wheels 71 are arranged on both sides of the frame body 70; a traction drive assembly 72 is poweredly connected to the wheels 71 and is used to drive the wheels 71 to move along the track 100; in this embodiment, two wheels 71 are arranged on each side of the frame body 70, and the traction drive assembly 72 is a servo motor equipped with a reducer, which drives the wheels 71 to rotate through the servo motor and the reducer. Specifically, a traction drive assembly 72 is arranged on each side of the frame body 70.

[0044] One end of the traction rod 73 is mounted on the frame body 70. In this embodiment, one end of the traction rod 73 is mounted on the frame body 70 via a ball joint. When the frame body 70 travels along the track 100, it drives the traction rod 73 to move.

[0045] The other end of the traction rod 73 is mounted on the measuring component 8. In this embodiment, a ball joint is provided at the other end of the traction rod 73, and a U-shaped connector 77 is provided at one end of the ball joint. The U-shaped connector 77 is connected to the measuring component 8. Through the two ball joints, the frame body 70 transmits power only to the measuring component 8, without affecting the offset of the measuring component 8 when it moves, and without affecting the measurement accuracy.

[0046] The frame body 70 drives the measuring component 8 along the track 100 via the traction rod 73. The measuring component 8 is used to measure the height difference, slope, and position information of the two tracks 100. The measuring component 8 is an existing product, with a built-in gyroscope and angle sensor. It works with a total station to measure the overall height, thereby detecting relevant parameters of the track 100. The specific structure of the measuring component 8 is not described in detail in this manual. Based on the deviation between the information detected by the measuring component 8 and the preset value, the control center controls the height adjustment component 2, height drive component 3, lateral adjustment component 5, and lateral drive component 6 to make corresponding adjustments.

[0047] Detection components 103 are installed on both sides of the main frame 70, and multiple identification plates 102 are spaced apart on the inner side of the track 100. The detection components 103 are used to identify different identification plates 102 and transmit the identified information to the controller 75. The identification plates 102 are equipped with QR codes, barcodes, or digital labels for recording location information. Through the location information, the measured height difference and slope information of that section of track 100 are classified and stored for subsequent overall data analysis. The detection components 103 are barcode scanners or industrial cameras.

[0048] The adjustment method includes the following steps: Step 1: Laying the track 100. Several track panel groups are placed in designated positions. Each track panel has four main beams 101, and each main beam 101 has a fine-tuning unit installed at both ends. The corresponding tracks 100 between two adjacent track panels are fixedly connected by welding.

[0049] Step two, preliminary adjustment: The lateral movement of the main beam 101 is adjusted by the lateral adjustment component 5 and the lateral drive component 6 to adjust the laying direction of the track 100; the height of both ends of the main beam 101 is adjusted by the height adjustment component 2 and the height drive component 3 to adjust the elevation of the track 100. During the preliminary adjustment, based on the set height value and in conjunction with the relative heights of the various height drive components 3, the ends of the main beam 101 are adjusted to the set range. Each set of track panels is adjusted individually.

[0050] Step 3, fine-tuning: The detection unit detects the slope and relative height difference of the two tracks 100 after the initial adjustment, and sends the detection information to the control center. The control center controls different lateral drive components 6 and height drive components 3 to operate according to the error between the slope and height difference and the preset value. During fine-tuning, each track panel is adjusted individually.

[0051] Step four, overall measurement: After the specified number of track panels have been fine-tuned, the detection unit moves from one end of the completed track panel to the other end and sends the overall measurement information to the control center. The control center controls the different lateral drive components 6 and height drive components 3 to operate according to the error between the slope and the height difference and the preset value.

[0052] When the driving torque of the lateral drive component 6 and / or the height drive component 3 exceeds the threshold during adjustment, the corresponding lateral drive component 6 and / or height drive component 3 stops adjusting, while other positions continue to be adjusted; when the driving torque is less than the threshold, adjustment continues. If, after all lateral drive components 6 and height drive components 3 have been adjusted, the driving torque of any lateral drive component 6 or height drive component 3 still exceeds the threshold, the control center issues a warning, and relevant technical personnel conduct on-site troubleshooting.

[0053] By setting up the sign 102, the location information can be associated with and stored in conjunction with the track geometric parameters (height difference, slope, etc.) measured synchronously by the measuring component 8. During subsequent data processing, defect location, and fine-tuning, there is no need for additional manpower to verify the location; the measurement data can be quickly categorized, retrieved, and accurately matched, significantly reducing the workload and improving the efficiency and targeted nature of track fine-tuning.

[0054] Elevation adjustment can be simplified and modeled as follows, such as Figure 2 As shown, the positions of the left and right outriggers 1 are simplified to points A and D; the intersections of the left and right tracks 100 and the main beam 101 are simplified to points B and C. A0, B0, C0, and D0 represent the target positions of the outriggers 1 and tracks 100, respectively; A2, B2, C2, and D2 represent the current positions of the outriggers 1 and tracks 100, respectively; and A1, B1, C1, and D1 represent the adjustment transition positions of the outriggers 1 and tracks 100, respectively.

[0055] Theoretically, there are 20 possible relationships between the position of each main beam 101 and the target position, such as... Figure 3 As shown, all adjustments are adapted to the adjustment method disclosed in this embodiment. All adjustment actions are decomposed into rotation and vertical translation with point B0 as the center. This can be obtained through the geometric relationship of similar triangles: A2-A1=B2-B1=C2-C1=D2-D1; A1-A0 / C1-C0=A0-B0 / B0-C0; D1-D0 / C1-C0=B0-D0 / B0-C0; Where B2-B1 and C1-C0 are the track 100 elevation deviation values; B0-C0 (the value in this embodiment is 1435mm) is the track panel structure design value; A0-B0 and C0-D0 are variables during the adjustment process; the lifting height of the left and right outriggers can be calculated using the above known data.

[0056] The horizontal translation of the beam is approximately simplified to the deviation value of the track direction.

[0057] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
