Description

Technical Field

[0001] This invention belongs to the field of rail transit engineering technology, specifically relating to an elevation fine-tuning mechanism adaptable to ultra-high terrain, a track panel fine-tuning vehicle using the elevation fine-tuning mechanism, and a track panel fine-tuning method based on the track panel fine-tuning vehicle. Background Technology

[0002] Currently, most ballastless track passenger dedicated lines use double-block ballastless track, with a design speed of up to 350 km / h. The safety, smoothness, and comfort of high-speed train operation must be supported by good track geometry. Track fine-tuning is a key link in track precision control. Based on the measurement data of the track detection system and the smoothness control indicators, the track adjustment amount is calculated to optimize the track linearity, which can ensure good wheel-rail matching and improve the safety, stability, and ride comfort of train operation.

[0003] Track panel fine-tuning involves both elevation and alignment fine-tuning. Elevation fine-tuning is primarily achieved through the interaction of elevation fine-tuning sleeves and elevation fine-tuning screws, while alignment fine-tuning is primarily achieved through the interaction of alignment fine-tuning sleeves and alignment fine-tuning screws. Currently, automatic or semi-automatic fine-tuning equipment exists, such as Chinese patent CN111851172A. However, these devices employ a single elevation fine-tuning sleeve posture, limiting their application to track panels with specific gauges or structures. This limited scope makes it difficult to meet the fine-tuning requirements of special track panels in ultra-high elevation sections. Summary of the Invention

[0004] This invention relates to an elevation fine-tuning mechanism adaptable to ultra-high terrain, a track panel fine-tuning vehicle using the elevation fine-tuning mechanism, and a track panel fine-tuning method based on the track panel fine-tuning vehicle, which can at least solve some of the defects of the prior art.

[0005] This invention relates to an elevation fine-tuning mechanism adaptable to ultra-high terrain. The elevation fine-tuning mechanism includes an elevation fine-tuning arm, an elevation fine-tuning sleeve adapted to be screwed onto an elevation adjusting screw on a track panel, a first elevation drive unit for driving the elevation fine-tuning arm to rotate around a vertical axis, and a second elevation drive unit for driving the elevation fine-tuning sleeve to rotate. The second elevation drive unit is mounted on the elevation fine-tuning arm. The vertical position of the elevation fine-tuning sleeve is adjustable.

[0006] As one implementation method, the second elevation drive unit is connected to the elevation fine-tuning screw sleeve through an elevation transmission link, wherein the elevation transmission link is a telescopic rod and its axis is parallel to the vertical.

[0007] As one implementation method, the elevation transmission link is a spring telescopic rod.

[0008] As one implementation method, the output end of the first elevation drive unit is provided with a mounting bracket, and multiple elevation mounting positions are provided on the mounting bracket. Each elevation mounting position is arranged sequentially along the vertical direction, and the elevation fine adjustment arm is selectively installed on one of the elevation mounting positions.

[0009] As one implementation method, the elevation fine-tuning arm is provided with bolt connection holes, and each elevation installation position is provided with bolt installation holes. The elevation fine-tuning arm is installed at the corresponding elevation installation position by adjusting bolts.

[0010] As one embodiment, the mounting frame includes two mounting plates, and the elevation fine-tuning arm is clamped between the two mounting plates and fixedly connected to the two mounting plates respectively.

[0011] As one implementation method, the second elevation drive unit can be detachably mounted on the elevation fine-tuning arm.

[0012] The present invention also relates to a track panel fine-tuning vehicle, including a vehicle body, a traveling mechanism at the bottom of the vehicle body, and an elevation fine-tuning module on the vehicle body. The elevation fine-tuning module includes two sets of elevation fine-tuning mechanisms disposed on the left and right sides of the vehicle body, and at least one set of elevation fine-tuning mechanisms adopts the elevation fine-tuning mechanism described above.

[0013] This invention also relates to a method for fine-tuning track panels, characterized in that it includes:

[0014] The condition of the track panel is monitored;

[0015] Based on the detected track panel condition, the track panel is finely adjusted using a track panel fine-tuning device, which is the aforementioned track panel fine-tuning vehicle.

[0016] The present invention has at least the following beneficial effects: the vertical position of the elevation fine-tuning screw sleeve is adjustable, which allows the elevation fine-tuning mechanism to adapt to the fine-tuning operation of the track panel at different height positions, and also to the fine-tuning operation of the track panel on curved sections. For example, for the track panel on superelevated sections, due to the existence of an angle, or for the track panel on curved sections, the outer rail is raised while the inner rail remains stationary, and the entire fine-tuning equipment is in an inclined state during operation. By dynamically adapting the vertical position of the elevation fine-tuning screw sleeve, the efficiency and adjustment accuracy of the track panel fine-tuning can be improved.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0027] Example 1

[0028] like Figures 1-4 This invention provides a track panel fine-tuning vehicle 1, including a first vehicle body 11, a first traveling mechanism at the bottom of the first vehicle body 11, the first traveling mechanism being adapted to travel on the track panel. A fine-tuning device is provided on the first vehicle body 11.

[0029] (1) In one embodiment, the first traveling mechanism includes a plurality of first traveling wheels. Preferably, the first vehicle body 11 is equipped with four first traveling wheels, which are arranged in a 2×2 array to ensure the stability and smoothness of the operation of the first vehicle body 11.

[0030] The first vehicle body 11 is preferably driven automatically, for example, at least some of the first traveling wheels are equipped with a travel drive motor. Optionally, the first vehicle body 11 can travel bidirectionally on the track panel, which can realize the purpose of bidirectional inspection of the track panel inspection vehicle, making the operation more flexible and effectively improving the work efficiency and inspection accuracy; the bidirectional travel mode can be, for example, by designing the travel drive motor as a motor that can drive in both forward and reverse directions.

[0031] In one embodiment, the aforementioned walking drive motor is a stepper motor, which can control the first vehicle body 11 to move at a certain stride, thereby driving the fine adjustment device to move at a certain stride. For example, the movement stride of the first vehicle body 11 can be set according to the distance between two adjacent fine adjustment points, or according to the distance between the elevation adjustment screws, or according to the distance between the track alignment adjustment screws. This can avoid the elevation fine adjustment arm 122 / track alignment fine adjustment arm 132 from frequently adjusting its posture, thereby improving the track panel adjustment efficiency and adjustment accuracy.

[0032] (2) In one embodiment, such as Figures 1-4 The aforementioned fine-tuning device includes an elevation fine-tuning module, which includes two sets of elevation fine-tuning mechanisms 12 disposed on the left and right sides of the first vehicle body 11.

[0033] like Figure 5 The elevation fine-tuning mechanism 12 includes an elevation fine-tuning arm 122, an elevation fine-tuning sleeve 124, a first elevation drive unit 121 for driving the elevation fine-tuning arm 122 to move, and a second elevation drive unit 123 for driving the elevation fine-tuning sleeve 124 to rotate. The elevation fine-tuning sleeve 124 is adapted to be screwed to the elevation adjustment screw on the track panel.

[0034] In one embodiment, the first elevation drive unit 121 drives the elevation fine-tuning arm 122 to rotate around a vertical axis, facilitating the rotation of the elevation fine-tuning arm 122 to the vicinity or away from the elevation adjusting screw, thus preventing interference between the elevation fine-tuning arm 122 and the elevation adjusting screw during the movement of the first vehicle body 11. The first elevation drive unit 121 may include, but is not limited to, a first elevation drive motor, the output shaft of which is parallel to the vertical axis. A rotary table can be connected to the output end of the first elevation drive unit 121, and the elevation fine-tuning arm 122 can be mounted on the rotary table. In another optional embodiment, the first elevation drive unit 121 drives the elevation fine-tuning arm 122 to perform lifting and lowering movements, similarly preventing interference between the elevation fine-tuning arm 122 and the elevation adjusting screw during the movement of the first vehicle body 11; in this solution, a cylinder, hydraulic cylinder, or other linear drive device can be used. Alternatively, the aforementioned first elevation drive unit 121 may employ a combined drive device capable of driving the elevation fine-tuning arm 122 to rotate around a vertical axis and to perform lifting and lowering movements. For example, the first elevation drive motor may be mounted on the output end of a lifting cylinder. The aforementioned first elevation drive unit 121 is mounted on the first vehicle body 11. Preferably, the aforementioned first elevation drive motor is equipped with a rotary encoder. The number of revolutions of the first elevation drive motor is obtained through the rotary encoder, thereby calculating the adjustment amount to achieve precise adjustment.

[0035] Preferably, the second elevation drive unit 123 is mounted on the elevation fine-tuning arm 122, for example, at the free end of the elevation fine-tuning arm 122. The second elevation drive unit 123 is preferably detachably mounted on the elevation fine-tuning arm 122 for easy inspection, maintenance, and replacement. The second elevation drive unit 123 may include, but is not limited to, a second elevation drive motor, the output shaft of which is also parallel to the vertical axis, and the elevation fine-tuning sleeve 124 is connected to the output shaft of the second elevation drive motor. Preferably, the second elevation drive motor is equipped with a rotary encoder, which obtains the rotational speed of the second elevation drive motor, thereby calculating the adjustment amount to achieve precise adjustment.

[0036] In one embodiment, the output end of the second elevation drive unit 123 is connected to the elevation fine-tuning sleeve 124 via a universal joint. This ensures the three-dimensional freedom of the elevation fine-tuning sleeve 124, facilitating the threaded connection between the sleeve and the adjustment screw, thereby reducing the positioning accuracy of the elevation fine-tuning arm 122 and improving operational efficiency. Furthermore, it enhances the smoothness of transmission between the second elevation drive unit 123, the sleeve 124, and the adjustment screw, preventing issues such as force buildup and effectively improving the track panel elevation adjustment accuracy. Preferably, a double universal joint structure 126 is used for even better transmission smoothness.

[0037] In one embodiment, the second elevation drive motor is a servo motor, which can start and stop quickly, improving the response speed of the elevation fine-tuning mechanism 12 and the accuracy of track panel elevation adjustment. Furthermore, by monitoring changes in the analog current of the servo motor, the tightness of the connection between the elevation fine-tuning sleeve 124 and the elevation adjusting screw can be automatically detected, automatically eliminating the connection gap between them and thus improving the accuracy of track panel elevation adjustment.

[0038] In the above-mentioned scheme in which the elevation fine-tuning arm 122 is driven to rotate around a vertical axis by the first elevation drive unit 121, the rotation radius of the elevation fine-tuning sleeve 124 relative to the vertical axis is further adjustable, so that the elevation fine-tuning mechanism 12 can adapt to the elevation adjustment of track panels with different structures / gauges.

[0039] The elevation adjustment arm 122 can be configured with adjustable arm length / rotation radius. Automatic adjustment can be used, for example, by configuring a drive device capable of driving the elevation adjustment arm 122 along its arm length direction (e.g., a guide rail is provided on the rotary table, and the drive device drives the elevation adjustment arm 122 to move along the guide rail). Manual adjustment can also be used. In one embodiment, the elevation adjustment arm 122 is a telescopic arm with a self-locking mechanism. In another embodiment, the elevation adjustment arm 122 has multiple connection positions, each sequentially arranged along the arm length direction, and one of these connection positions is selected to connect to the first elevation drive unit 121, thus achieving the goal of adjustable rotation radius / arm length of the elevation adjustment arm 122.

[0040] As a specific implementation method, such as Figure 5 A mounting bracket 125 is provided at the output end of the first elevation drive unit 121 (for structures with a rotary table, the mounting bracket 125 is fixed to the rotary table). The elevation fine-tuning arm 122 is fixed to the mounting bracket 125 by adjusting bolts. Correspondingly, multiple bolt connection holes are provided on the elevation fine-tuning arm 122, and each bolt connection hole is arranged sequentially along the arm length direction of the elevation fine-tuning arm 122. Further, the elevation fine-tuning arm 122 and the mounting bracket 125 are connected by multiple adjusting bolts, which can improve the reliability of the connection between the two. Preferably, the spacing between each bolt connection hole is the same, which facilitates the selection and adjustment of the connection position. Optionally, such as Figure 5The mounting bracket 125 includes two mounting plates 1251, which are arranged in parallel and spaced apart, with the spacing between them being the same as the width / thickness of the elevation fine-tuning arm 122. The two mounting plates 1251 are respectively provided with bolt through holes (the number of which is set according to the number of adjusting bolts). The elevation fine-tuning arm 122 is sandwiched between the two mounting plates 1251. After the adjusting bolt passes through the bolt through hole on one of the mounting plates 1251, the bolt connection hole on the elevation fine-tuning arm 122, and the bolt through hole on the other mounting plate 1251 in sequence, it is locked with a nut.

[0041] Obviously, the following method can also be adopted: multiple horizontal mounting positions are set on the aforementioned mounting frame 125, and each horizontal mounting position is arranged sequentially along the arm length direction of the elevation fine-tuning arm 122, with the elevation fine-tuning arm 122 selectively mounted on one of the horizontal mounting positions. In comparison, setting multiple connection positions on the elevation fine-tuning arm 122 can improve the structural compactness of the elevation fine-tuning mechanism 12 and also avoid problems such as increased weight caused by excessive length of the mounting frame 125.

[0042] In cases where the elevation adjustment arm 122 is not equipped with a lifting drive device, the installation height of the elevation adjustment arm 122 can be made adjustable, thereby increasing the applicability of the track panel adjustment vehicle 1. Preferably, multiple elevation installation positions are provided on the mounting frame 125, with each position arranged sequentially along the vertical direction. The elevation adjustment arm 122 is selectively installed in one of these elevation installation positions. For the installation of the elevation adjustment arm 122 in the elevation installation position, it is still preferable to use adjusting bolts for fixing; this will not be elaborated upon here.

[0043] Two sets of elevation fine-tuning mechanisms 12 are used to adjust the elevation adjusting screws on both sides of the track panel. Preferably, the arrangement direction of the two sets of elevation fine-tuning mechanisms 12 is parallel to the transverse direction of the first car body 11 (when the first car body 11 travels on the track panel, the transverse direction of the first car body 11 is parallel to the transverse direction of the track panel), which can ensure the balance of the force on the first car body 11.

[0044] (3) In one embodiment, the fine adjustment device includes a track alignment fine adjustment module 13.

[0045] like Figure 6 The track alignment fine adjustment module 13 includes a track alignment fine adjustment arm 132, a track alignment fine adjustment screw sleeve 134, a first track alignment drive unit 131 for driving the movement of the track alignment fine adjustment arm 132, and a second track alignment drive unit 133 for driving the rotation of the track alignment fine adjustment screw sleeve 134. The track alignment fine adjustment screw sleeve 134 is adapted to be screwed to the track alignment adjustment screw on the track panel.

[0046] The aforementioned first track alignment drive unit 131 is used to drive the track alignment fine-tuning arm 132 closer to or further away from the track alignment adjusting screw, facilitating the track alignment fine-tuning arm 132 to complete track alignment adjustment operations and adapting to track panel adjustment operations with different gauges, as well as preventing interference between the track alignment fine-tuning arm 132 and the track alignment adjusting screw during the movement of the first car body 11. Preferably, the aforementioned first track alignment drive unit 131 adopts a multi-stage drive structure, which can flexibly position the spatial posture of the track alignment fine-tuning arm 132 and the track alignment fine-tuning screw sleeve 134, improving the accuracy and efficiency of track alignment adjustment, and better protecting the equipment.

[0047] In one embodiment, each drive structure has an output shaft parallel to the vertical axis, and the track-direction fine-tuning arm 132 is connected to the output shaft of the final-stage drive structure. Adjacent drive structures are connected by articulated arms, where the articulated arm is connected to the output shaft of the previous-stage drive structure, and the next-stage drive structure is fixedly connected to the articulated arm. In this embodiment, a two-stage drive structure combination is used, which can better achieve the driving and spatial positioning of the track-direction fine-tuning arm 132. Preferably, the drive structure includes, but is not limited to, a first track-direction drive motor, the output shaft of which constitutes the aforementioned output shaft. Preferably, the first track-direction drive motor is equipped with a rotary encoder, which obtains the rotation number of the first track-direction drive motor, thereby calculating the adjustment amount to achieve precise adjustment.

[0048] In another optional embodiment, the first track alignment drive unit 131 is used to drive the track alignment fine adjustment arm 132 to perform lifting and lowering movements, or a combination of lifting and lowering movements and rotational movements. It can also flexibly position the track alignment fine adjustment arm 132 and prevent interference between the track alignment fine adjustment arm 132 and the track alignment adjustment screw during the movement of the first vehicle body 11.

[0049] Preferably, such as Figure 6 The aforementioned track alignment fine-tuning arm 132 is an L-shaped arm, comprising a horizontal arm 1321 and a vertical arm 1322. The horizontal arm 1321 is connected to the first track alignment drive unit 131, and the top end of the vertical arm 1322 is connected to the horizontal arm 1321. The second track alignment drive unit 133 is installed at the bottom of the vertical arm 1322. The aforementioned track alignment fine-tuning arm 132 can be a one-piece molded structure, or the horizontal arm 1321 and the vertical arm 1322 can be detachably connected. When the horizontal arm 1321 and the vertical arm 1322 are detachably connected, it facilitates the installation and maintenance of the track alignment fine-tuning module 13. The second track alignment drive unit 133 and the track alignment fine-tuning sleeve 134 can be replaced and maintained by removing the vertical arm 1322 from the horizontal arm 1321. It also facilitates the storage and retrieval of the track alignment fine-tuning arm 132.

[0050] The aforementioned second track-direction drive unit 133 is preferably detachably mounted on the track-direction fine-tuning arm 132 for easy inspection, maintenance, and replacement. This second track-direction drive unit 133 includes, but is not limited to, a second track-direction drive motor. The output shaft of this second track-direction drive motor is axially parallel to the transverse direction of the first vehicle body 11, or in other words, parallel to the axial direction of the first traveling wheel. The track-direction fine-tuning sleeve 134 is connected to the output shaft of the second track-direction drive motor. Preferably, the aforementioned second track-direction drive motor is equipped with a rotary encoder. The rotational speed of the second track-direction drive motor is obtained through the rotary encoder, thereby calculating the adjustment amount to achieve precise adjustment.

[0051] In one embodiment, the output end of the second track alignment drive unit 133 is connected to the track alignment fine adjustment sleeve 134 via a universal joint, which can ensure the three-dimensional degree of freedom of the track alignment fine adjustment sleeve 134. On the one hand, it facilitates the threaded connection between the track alignment fine adjustment sleeve 134 and the track alignment adjusting screw, which can correspondingly reduce the positioning accuracy of the track alignment fine adjustment arm 132 and improve the work efficiency. On the other hand, it can improve the transmission smoothness between the second track alignment drive unit 133, the track alignment fine adjustment sleeve 134, and the track alignment adjusting screw, avoid the occurrence of situations such as force buildup, and effectively improve the track alignment adjustment accuracy of the track panel.

[0052] In one embodiment, the second track alignment drive motor is a servo motor, which can start and stop quickly, improving the response speed of the track alignment fine-tuning module 13 and the track alignment adjustment accuracy. Furthermore, by monitoring the changes in the analog current of the servo motor, the tightness of the connection between the track alignment fine-tuning sleeve 134 and the track alignment adjusting screw can be automatically detected, automatically eliminating the connection gap between the track alignment fine-tuning sleeve 134 and the track alignment adjusting screw, thereby improving the track alignment adjustment accuracy of the track panel.

[0053] In one embodiment, such as Figure 6A track alignment fine adjustment seat 1351 is provided at the bottom end of the track alignment fine adjustment arm 132. A screw sleeve adaptive mechanism 135 is provided on the track alignment fine adjustment seat 1351 to enable the track alignment fine adjustment screw sleeve 134 to adapt to the track alignment fine adjustment process and / or the track elevation fine adjustment process. Specifically, during the track alignment fine adjustment process, the relative position between the track alignment fine adjustment screw sleeve 134 and the second track alignment drive unit 133 is kept stable, and during the track elevation fine adjustment process, the track alignment fine adjustment screw sleeve 134 can keep moving. Preferably, the aforementioned adaptive screw sleeve mechanism 135 includes a base plate, a second track direction drive unit 133 is mounted on the base plate, and a track direction fine-tuning screw sleeve 134 is mounted on the output end of the second track direction drive unit 133; the adaptive screw sleeve mechanism 135 further includes a vertical adaptive structure and / or a track direction adaptive structure, the track direction adaptive structure is used to keep the relative position between the track direction fine-tuning screw sleeve 134 and the second track direction drive unit 133 stable during the track track direction fine-tuning process, and the vertical adaptive structure is used to keep the track direction fine-tuning screw sleeve 134 moving in sync during the track track elevation fine-tuning process.

[0054] In one embodiment, such as Figure 7 The vertical adaptive structure includes at least two sets of vertical guide components, each including a cooperating vertical guide post 1352 and a vertical guide sleeve. The vertical guide sleeve slides on the vertical guide post 1352, driving the substrate to move up and down. The track adaptive structure includes at least two sets of track guide components, each including a cooperating track guide post 1353 and a track guide sleeve. The track guide sleeve slides on the track guide post 1353, driving the substrate to move laterally. Understandably, when both a vertical adaptive structure and a track-oriented adaptive structure are included, they work together to form a two-dimensional guiding mechanism. For example, the track-oriented adaptive structure also includes a track-oriented movable frame, with each track-oriented guide post 1353 fixed on the track-oriented movable frame and each track-oriented guide sleeve fixed on the base plate, which can drive the base plate to slide along the track-oriented guide post 1353. Each vertical guide sleeve is fixed on the track-oriented movable frame, which can drive the track-oriented movable frame to slide along the vertical guide post 1352, and each vertical guide post 1352 is fixed on the track-oriented fine-tuning seat 1351.

[0055] Preferably, the aforementioned rail alignment fine-tuning seat 1351 is detachably mounted on the rail alignment fine-tuning arm 132, which facilitates the installation, inspection and maintenance of related equipment.

[0056] By configuring the adaptive screw sleeve mechanism 135, the track alignment fine-tuning screw sleeve 134 can adapt to the track panel adjustment process, which can effectively improve the working reliability and smoothness of the fine-tuning device.

[0057] In the above scheme, the spatial position of the track alignment fine-tuning screw sleeve 134 can be adjusted by means of the aforementioned screw sleeve adaptive mechanism 135. Combined with the spatial positioning of the track alignment fine-tuning arm 132 by the first track alignment drive unit 131, the positioning accuracy of the track alignment fine-tuning screw sleeve 134 can be effectively improved. Specifically, the first track alignment drive unit 131 can achieve coarse positioning of the track alignment fine-tuning screw sleeve 134, and then the aforementioned screw sleeve adaptive mechanism 135 can perform fine positioning, so that the track alignment fine-tuning screw sleeve 134 can be quickly screwed into the track alignment adjusting screw. In the above scheme where the first track alignment drive unit 131 adopts a multi-stage drive structure and each drive structure is driven by a motor, combined with the screw sleeve adaptive mechanism 135, the fine-tuning device can be adapted to track panel adjustment operations of different specifications / different elevations.

[0058] Example 2

[0059] This embodiment provides an elevation fine-tuning mechanism 12 that can adapt to ultra-high terrain. It can be used as the elevation fine-tuning mechanism 12 in the above embodiment one, or the elevation fine-tuning mechanism 12 therein can be optimized.

[0060] The elevation fine-tuning mechanism 12 includes an elevation fine-tuning arm 122, an elevation fine-tuning sleeve 124 adapted to be screwed to an elevation adjusting screw on the track panel, a first elevation drive unit 121 for driving the elevation fine-tuning arm 122 to rotate around a vertical axis, and a second elevation drive unit 123 for driving the elevation fine-tuning sleeve 124 to rotate. The second elevation drive unit 123 is mounted on the elevation fine-tuning arm 122. The relevant structure can be referred to the content in Embodiment 1 above, and will not be repeated here.

[0061] Furthermore, the vertical position of the elevation fine-tuning sleeve 124 is adjustable, which allows the elevation fine-tuning mechanism 12 to adapt to the fine-tuning operation of the track panel at different height positions, and also to the fine-tuning operation of the track panel on curved sections. For example, for track panels on superelevated sections, due to the presence of an angle, or for track panels on curved sections, the outer rail is raised while the inner rail remains stationary, and the entire fine-tuning equipment is in an inclined state during operation. By dynamically adapting the vertical position of the elevation fine-tuning sleeve 124, the efficiency and accuracy of track panel fine-tuning can be improved.

[0062] In one embodiment, the second elevation drive unit 123 is connected to the elevation fine-tuning sleeve 124 via an elevation transmission link 3, wherein the elevation transmission link 3 is a telescopic rod with its axis parallel to the vertical. Preferably, the elevation transmission link 3 is a spring telescopic rod. By extending or retracting the elevation transmission link 3, the vertical position of the elevation fine-tuning sleeve 124 can be adjusted.

[0063] In one embodiment, the output end of the first elevation drive unit 121 is provided with a mounting bracket 125, on which a plurality of elevation mounting positions are provided. The elevation mounting positions are arranged sequentially along the vertical direction, and the elevation fine-tuning arm 122 is selectively installed on one of the elevation mounting positions. For the structure of the mounting bracket 125 and the connection between the elevation fine-tuning arm 122 and the mounting bracket 125, please refer to the relevant content in Embodiment 1 above, which will not be repeated here.

[0064] Preferably, the combination of the above two methods can improve the adjustment efficiency and accuracy of the vertical position of the elevation fine-tuning sleeve 124. For example, coarse adjustment is performed by selecting the elevation mounting position on the mounting bracket 125, and fine adjustment is performed by extending and retracting the elevation transmission link 3, which yields good results.

[0065] Example 2

[0066] like Figures 1-4 as well as Figure 8 This embodiment provides a track panel inspection vehicle, including a second vehicle body 21, with a second traveling mechanism at the bottom of the second vehicle body 21, which is adapted to travel on the track panel. A track panel inspection unit is provided on the second vehicle body 21.

[0067] In one embodiment, the track panel detection unit includes at least one of a prism 22, a gauge sensor for measuring the track panel gauge, and a level sensor for measuring the track panel levelness, preferably all three. When used with a total station, it can calculate deviations in the track panel's orientation, elevation, levelness, and gauge, which helps guide workers to fine-tune the track panel.

[0068] In one embodiment, the second traveling mechanism includes a plurality of second traveling wheels. In another embodiment, the second vehicle body 21 is equipped with three second traveling wheels arranged in a triangular pattern. This simplifies the structure of the second vehicle body 21, reduces the number of components and the space occupied, and facilitates the transportation of the second vehicle body 21, while ensuring the stability and smoothness of its operation. Specifically, two of the second traveling wheels are arranged at one of the transverse ends of the second vehicle body 21, and the other second traveling wheel is arranged at the other transverse end of the second vehicle body 21.

[0069] Optionally, the second car body 21 includes a first frame and a second frame, both of which are elongated frames. The length direction of the first frame is perpendicular to the axle axis of the second traveling wheels, and the length direction of the second frame is parallel to the axle axis of the second traveling wheels. The first frame and the second frame are connected to form a T-shaped second car body 21, with two second traveling wheels arranged on the first frame and one second traveling wheel arranged on the second frame. Using a T-shaped second car body 21 simplifies the structure of the second car body 21 while ensuring its operational stability and smoothness. The aforementioned prism 22 is preferably disposed on the second frame, for example, in the middle position of the second frame. When the second car body 21 travels on the track panel, the prism 22 is located on the centerline of the track panel.

[0070] The first and second frames can be detachably assembled to facilitate the storage and transportation of the second vehicle body 21. Conventional detachable connection methods such as bolt connections are applicable to this embodiment. In particular, if the first and second frames are of the same length, the second vehicle body 21 can be placed in a cargo box after being disassembled into two frames, which facilitates the packaging, storage and transportation of equipment components.

[0071] The second vehicle body 21 is preferably driven automatically, for example, at least some of the second traveling wheels are equipped with a travel drive motor. Optionally, the second vehicle body 21 can travel bidirectionally on the track panel, enabling bidirectional inspection by the track panel inspection vehicle, making the operation more flexible and effectively improving work efficiency and inspection accuracy; the bidirectional travel mode can be achieved, for example, by designing the travel drive motor as a motor that can drive in both forward and reverse directions.

[0072] In one embodiment, the aforementioned walking drive motor is a stepper motor, which can control the second vehicle body 21 to move at a certain step, thereby driving the track panel detection unit to move at a certain step. For example, the movement step of the second vehicle body 21 can be set according to the distance between two adjacent detection points, or according to the distance between the elevation adjustment screws, or according to the distance between the track direction adjustment screws, which can improve the track panel measurement accuracy.

[0073] Example 3

[0074] like Figure 8 This embodiment provides a track panel inspection vehicle, which is optimized based on the track panel inspection vehicle provided in Embodiment 2 above. Specifically:

[0075] Multiple prisms 22 are provided on the second vehicle body 21. Each prism 22 is arranged sequentially and at intervals along the transverse direction of the second vehicle body 21. For example, each prism 22 is arranged on the second vehicle frame and sequentially along the length of the second vehicle frame.

[0076] By setting multiple prisms 22 on the second car body 21, synchronous tracking and measurement of the left and right track panels can be achieved. Based on the measurement results, the spatial attitude of the track panels can be calculated, and the movement status of the track panels can be fed back in real time. This allows for the analysis of the optimal adjustment scheme, real-time adjustment of the control strategy, and correction of control parameters. Compared with the traditional scheme using a single prism 22 + sensors (gauge sensor, level sensor, etc.), the multi-prism 22 detection scheme provided in this embodiment can effectively improve detection accuracy and efficiency, and avoid the problem of decreased detection accuracy due to sensor detection errors. Furthermore, by simultaneously setting gauge sensors and / or level sensors on the second car body 21, combined with multiple prisms 22, the detection data based on the prisms 22 and the sensor detection data can complement and verify each other, thereby significantly improving the detection accuracy of the track panels.

[0077] Furthermore, the spacing between each prism 22 is adjustable. For example, each prism 22 can be detachably installed on the second vehicle body 21. The detachable installation method can be screw connection, snap connection, etc., or a slide rail can be installed on the second vehicle body 21, and each prism 22 bracket can be slidably mounted on the slide rail.

[0078] Example 4

[0079] like Figure 2 and Figure 3 This embodiment provides a track panel detection device, including multiple track inspection trolleys 2, which are connected in series. At least some of the track inspection trolleys 2 adopt the track panel detection vehicle provided in Embodiment 2 above, or adopt the track panel detection vehicle provided in Embodiment 3 above.

[0080] In this design, the second traveling mechanism of one or more track inspection trolleys 2 can be equipped with a power drive, or all the second traveling mechanisms of the track inspection trolleys 2 can be equipped with a power drive. Of course, in the case of a scheme in which all or more track inspection trolleys 2 are equipped with power drives, in actual application, some of the power drives can be kept out of use.

[0081] In one embodiment, the second traveling mechanism is powered by a stepper motor, which controls each track inspection trolley 2 to move with a certain stride. Preferably, by controlling the stride of the track inspection trolley 2, the first track inspection trolley 2 moves to the next adjustment point of the track panel, the second track inspection trolley 2 moves to the original position of the first track inspection trolley 2, the third track inspection trolley 2 moves to the original position of the second track inspection trolley 2, and so on, until the nth track inspection trolley 2 moves to the original position of the (n-1)th track inspection trolley 2. Generally, the prisms 22 on the track inspection trolley 2 are installed in the same position, so the distance between two adjacent prisms 22 is preferably equal to n trolley strides. The above method can effectively improve the measurement accuracy of the track panel.

[0082] In one embodiment, the track inspection trolleys 2 are detachably connected, allowing the track panel inspection device to be divided into multiple track inspection trolleys 2. Each track inspection trolley 2 can operate independently or be used for inspection of other track panels. Furthermore, the number of track inspection trolleys 2 can be increased or decreased according to actual needs, effectively improving the applicability and operational flexibility of the track panel inspection device. Existing detachable connection structures are suitable for this embodiment, such as using connecting rods 3 to be detachably connected to the second car bodies 21 of the two track inspection trolleys 2 (e.g., connecting rods 3 are fixed to the second car bodies 21 by bolts).

[0083] In one embodiment, the spacing between the track inspection trolleys 2 is adjustable, which allows for a higher degree of matching between the spacing between the track inspection trolleys 2 and the trolley movement stride, further improving the track panel measurement accuracy. In the above-mentioned scheme where the connecting rod 3 is detachably connected to the second car body 21 of the two track inspection trolleys 2 respectively, multiple bolt connection holes can be provided on the connecting rod 3, and bolts can be installed in one or more of these bolt connection holes; alternatively, a telescopic connecting rod 3 with self-locking can be used to connect the two track inspection trolleys 2. In another alternative, a lead screw is used to connect the two track inspection trolleys 2. Nuts can be installed on the second body 21 of each of the two track inspection trolleys 2 (e.g., the second frame mentioned above). The lead screw is screwed to each of the two nuts (preferably with opposite thread directions), and the axis of the lead screw is perpendicular to the axis of the axle of the second traveling wheel. By rotating the lead screw, the two track inspection trolleys 2 can be moved closer or further apart. Furthermore, by selecting the thread pitch and controlling the thread accuracy, the accuracy of track panel measurement can be further improved. This solution allows for both adjustment of the distance between the two track inspection trolleys 2 and detachable connection between them.

[0084] Example 5

[0085] This embodiment provides a track panel fine-tuning detection device, which has track panel detection function and track panel fine-tuning function.

[0086] (1) Optionally, the track panel fine-tuning and testing device includes a third car body, and a third traveling mechanism is provided at the bottom of the third car body. The third traveling mechanism is adapted to travel on the track panel. A fine-tuning unit and a track panel testing unit are provided on the third car body. From another perspective, it can also be understood that a track panel testing unit is added to the above-mentioned track panel fine-tuning car 1.

[0087] The structure of the track panel detection unit can be referred to the relevant content in Embodiment 2 above. Specifically, when the first car body 11 includes a frame, a crossbeam can be installed on the frame to arrange the track panel detection unit.

[0088] Preferably, multiple prisms 22 can be arranged longitudinally on the third vehicle body; the power drive of the third traveling mechanism is a stepper motor drive, and the distance between two adjacent prisms 22 is preferably equal to n times the moving strides of the third vehicle body. By controlling the moving strides of the third vehicle body, when the first prism 22 moves to the next adjustment point of the track panel, the second prism 22 moves to the original position of the first prism 22, the third prism 22 moves to the original position of the second prism 22, and so on, until the nth prism 22 moves to the original position of the (n-1)th prism 22. This method can effectively improve the measurement accuracy of the track panel.

[0089] (2) Optionally, the track panel fine adjustment and detection device includes a track panel fine adjustment vehicle 1 and a track inspection vehicle 2, wherein the track panel fine adjustment vehicle 1 and the track inspection vehicle 2 are connected; wherein the track panel fine adjustment vehicle 1 can be the track panel fine adjustment vehicle 1 provided in the above embodiment 1, and the track inspection vehicle 2 can be the track panel detection vehicle in the above embodiment 2, then the first vehicle body 11 is connected to the second vehicle body 21.

[0090] The first vehicle body 11 and the second vehicle body 21 can be driven automatically, or only the first vehicle body 11 or the second vehicle body 21 can be driven automatically, while the other vehicle body moves automatically.

[0091] Preferably, the track panel fine-tuning vehicle 1 and the track inspection vehicle 2 are detachably connected, for example, the first vehicle body 11 and the second vehicle body 21 are detachably connected. Thus, the aforementioned track panel fine-tuning and inspection device can be divided into the track panel fine-tuning vehicle 1 and the track inspection vehicle 2. The track panel fine-tuning vehicle 1 and the track inspection vehicle 2 can work independently, or be used for the inspection / fine-tuning of other track panels. Furthermore, different track panel fine-tuning vehicles 1 or different track inspection vehicles 2 can be configured for the track inspection vehicle 2 according to actual conditions, thereby effectively improving the applicability and operational flexibility of the aforementioned track panel fine-tuning and inspection device. Existing detachable connection structures are all applicable to this embodiment, such as using connecting rods 3 to be detachably connected to the first vehicle body 11 and the second vehicle body 21 respectively (e.g., connecting rods 3 are fixedly connected to the first vehicle body 11 and the second vehicle body 21 respectively by bolts).

[0092] In one embodiment, the first car body 11 and the second car body 21 are connected by a connecting rod 3, the axis of which is perpendicular to the axis of the first traveling wheel; at least one car body is connected to the connecting rod 3 via a universal joint, preferably with a universal joint connected to each end of the connecting rod 3. Based on this structure, smooth transmission between the track panel fine-tuning car 1 and the track inspection trolley 2 can be ensured, avoiding situations such as force buildup, especially suitable for situations where one car body is automatically driven and the other follows along; it can improve or avoid the reduction in track panel detection accuracy / track panel adjustment accuracy caused by displacement errors of the track panel fine-tuning car 1 and the track inspection trolley 2; in addition, the above structure can also better ensure the operational stability and smoothness of the track panel fine-tuning detection device on curved track panels, as well as displacement accuracy. The connecting rod 3 is detachably connected to the universal joint, and / or the universal joint is detachably mounted on the corresponding car body.

[0093] In one embodiment, such as Figures 1-4 The first car body 11 includes a frame frame, and the second car body 21 is housed within the frame of the first car body 11 and fixedly connected to the first car body 11. The two are connected to form a fine-tuning detection mechanism 100. This structure can effectively improve the structural compactness and integration of the track panel fine-tuning detection device and reduce its volume while ensuring the track panel detection function and track panel fine-tuning function. More importantly, the track panel detection unit on the second car body 21 is closer to the fine-tuning unit on the first car body 11. The fine-tuning unit can perform fine-tuning processing on the track panel adjustment points detected by the track panel detection unit nearby, which can improve the track panel adjustment accuracy.

[0094] Furthermore, the first vehicle body 11 also includes a cover plate that covers the frame. When the cover plate abuts against the upper surface of the second vehicle body 21, it effectively constrains the second vehicle body 21, improving its smooth operation and thus increasing detection accuracy. It also enhances the structural integrity of the first and second vehicle bodies 11 and improves aesthetics. The cover plate is detachably connected to or hinged to the frame, facilitating inspection and maintenance of the second vehicle body 21. Since the prism 22 on the second vehicle body 21 needs to protrude through the cover plate, clearance holes are correspondingly provided on the cover plate.

[0095] As a preferred embodiment, the cross-section of the first vehicle body 11 is U-shaped, meaning that the two lateral sides of the first vehicle body 11 are higher and the middle is lower. Based on this structure, a better detection field of view can be provided. While meeting the arrangement requirements of the elevation fine-tuning module, the track alignment fine-tuning module 13, etc., it avoids the impact on the total station's acquisition of information from the prism 22 when using a conventional planar frame. This solution is particularly suitable for situations where the prism 22 is arranged on the first vehicle body 11 or the second vehicle body 21 is housed within the frame of the first vehicle body 11. However, it is also applicable when the second vehicle body 21 is arranged in front of or behind the first vehicle body 11, effectively improving the information acquisition field of view of the total station and avoiding the need for the prism 22 to be supported too high. Preferably, the middle U-shaped groove of the first vehicle body 11 adopts a clear design, meaning that no other devices besides the prism 22 that may extend into it are placed in the middle U-shaped groove to avoid obstructing the detection field of view.

[0096] (3) Optionally, the track panel fine adjustment and testing device includes a track panel fine adjustment vehicle 1 and multiple track inspection trolleys 2, wherein the track panel fine adjustment vehicle 1 can be the track panel fine adjustment vehicle 1 provided in the above embodiment 1;

[0097] In one embodiment, all track inspection trolleys 2 are adjacent to and connected to the track panel fine-tuning car 1 (the arrangement where the second car body 21 is housed within the frame of the first car body 11 is also clearly an adjacent connection arrangement). In another embodiment, some track inspection trolleys 2 are connected adjacent to the track panel fine-tuning car 1, while the remaining track inspection trolleys 2 are connected in series with the track inspection trolleys 2 adjacent to the front and / or rear of the track panel fine-tuning car 1. For example, multiple track inspection trolleys 2 can be connected to form the track panel detection device in the fourth embodiment described above (at least one of the track inspection trolleys 2 is connected to the track panel fine-tuning car 1).

[0098] Preferably, referring to the relevant content in Part (2) above, the track inspection trolley 2 and the track panel fine-tuning trolley 1 can adopt a connection structure of connecting rod 3 + universal joint.

[0099] Preferably, referring to the relevant content in Part (2) above, the first vehicle body 11 includes a frame frame, wherein one track inspection trolley 2 is housed within the frame of the first vehicle body 11 and fixedly connected to the first vehicle body 11, while the other track inspection trolleys 2 are located outside the first vehicle body 11.

[0100] Similarly, the first vehicle body 11 and the second vehicle body 21 can be driven automatically, or only the first vehicle body 11 or the second vehicle body 21 can be driven automatically, while the other vehicle body moves automatically.

[0101] Similarly, the track panel fine-tuning vehicle 1 and the track inspection trolley 2, and the track inspection trolley 2 and the track inspection trolley 2 are preferably detachably connected, which can effectively improve the applicability and operational flexibility of the above-mentioned track panel fine-tuning and inspection device.

[0102] For other structural details of the track panel fine-tuning and testing device, please refer to the relevant content in Part (2) above.

[0103] Example 6

[0104] This invention provides a method for fine-tuning a track panel, comprising:

[0105] The condition of the track panel is monitored;

[0106] Based on the detected track panel condition, the track panel is finely adjusted using a track panel fine-tuning device, which is the track panel fine-tuning vehicle 1 described in Embodiment 1 or Embodiment 2 above.

[0107] As a specific implementation plan, the method specifically includes:

[0108] Step 101: Install a total station on the centerline of the track panel and set up a track panel static geometry measuring instrument at the track panel adjustment points. The track panel static geometry measuring instrument is located on the back line of the total station. The track panel static geometry measuring instrument includes a precision prism 22, a gauge sensor for measuring the track gauge of the track panel at the corresponding adjustment point, and a level sensor for measuring the levelness of the track panel at the corresponding adjustment point. The objective lens center of the total station is at the same height as the precision prism 22 of the track panel static geometry measuring instrument.

[0109] Step 102: The coordinates of the precision prism 22 on the track panel static geometry measuring instrument are obtained by measuring the precision prism 22 with a total station. The track gauge and levelness of the track panel at the corresponding adjustment point are measured by the track gauge sensor and level sensor on the track panel static geometry measuring instrument. The coordinates of the precision prism 22 on the track panel static geometry measuring instrument, the track gauge and levelness of the track panel at the corresponding adjustment point together constitute the measured value of the track panel at the adjustment point.

[0110] Step 103: Calculate the deviations of the track panel at the corresponding adjustment point in terms of lateral direction, elevation, gauge, and levelness based on the measured values ​​of the track panel at the corresponding adjustment point. Calculate the adjustment amount of the track panel at the adjustment point based on the deviations in lateral direction, elevation, gauge, and levelness. Based on the adjustment amount, adjust the track panel at the corresponding adjustment point using the track panel fine-tuning equipment.

[0111] Preferably, there are multiple track panel static geometric state measuring instruments, which are sequentially arranged at several adjustment points on the track panel along the track panel direction. The precision prisms 22 of the multiple track panel static geometric state measuring instruments are at the same height, and the multiple precision prisms 22 form a target prism 22.

[0112] The track panel static geometric state measuring instrument can be the track panel inspection vehicle provided in Embodiment 3 or Embodiment 4, or multiple track panel static geometric state measuring instruments can be connected in series to form the track panel inspection device in Embodiment 5.

[0113] When the track panel fine-tuning equipment is connected or integrated with the track panel inspection vehicle, the track panel fine-tuning and inspection device provided in Embodiment Six can be formed accordingly.

[0114] Preferably, for cases with multiple track panel static geometry measuring instruments, the following steps can be used instead of step 103 above:

[0115] Based on the measured values ​​of the track panels at each adjustment point, the deviations of the track panels at the corresponding adjustment points by the static geometric state measuring instrument for each track panel are calculated in terms of lateral direction, elevation, gauge, and levelness.

[0116] A correlational mathematical model of track adjustment points is established. Based on the mathematical model, the adjustment amount of the target adjustment points is determined. The track fine-tuning equipment is controlled by control software to adjust the target adjustment points.

[0117] In one embodiment of the mathematical model relating track panel adjustment points, the adjustment amount δ is input at the i-th adjustment point. i Δ i0 To Δ in Let be the disturbance displacement of other adjustment points caused by the adjustment of the i-th adjustment point (which can be obtained through displacement sensors, etc.); based on the obtained disturbance displacement of each adjustment point, a training set is acquired, and a regression analysis model is established using a neural network to obtain the disturbance value of the input adjustment amount on other points; then the true adjustment amount of point i is...

[0118]

[0119] In another embodiment, a mathematical model relating the track panel adjustment points is determined by stiffness calculation. Specifically, a torque F is input at the i-th adjustment point, and the adjustment displacement Δ at that i-th adjustment point is measured. i The calculated stiffness value is

[0120]

[0121] Obtain the disturbance displacement of other adjustment points caused by the adjustment of the i-th adjustment point, and calculate the disturbance displacement Δ of each adjustment point.ij The relevant stiffness between the adjustment points can be calculated:

[0122]

[0123] The displacement change at each adjustment point can be calculated using the relevant stiffness under a fixed input torque.

[0124] Furthermore, after the current target adjustment point is adjusted, the static geometric state measuring instruments for each track panel are moved. The first track panel static geometric state measuring instrument is moved to the next adjacent adjustment point of the track panel, and the second track panel static geometric state measuring instrument is moved to the original position of the first track panel static geometric state measuring instrument. The third track panel static geometric state measuring instrument is moved to the original position of the second track panel static geometric state measuring instrument, and so on. The nth track panel static geometric state measuring instrument is moved to the original position of the (n-1)th track panel static geometric state measuring instrument. Then, the adjustment operation for the next adjustment point is carried out.

[0125] In this scheme, for a target adjustment point, the track panel status of a single adjustment point is not used as the detection benchmark. Instead, a certain track panel section where the adjustment point is located is selected as the detection benchmark. The rigidity characteristics of the track panel are fully considered, and the adjustment amount of the target adjustment point is determined on this basis. This avoids affecting the track panel status of adjacent adjustment points when performing adjustment work, thus effectively improving the track panel adjustment accuracy.

[0126] Furthermore, for situations involving multiple track panel static geometry measuring instruments and multiple track panel fine-tuning devices, the above method also includes:

[0127] Step 201: Based on the static geometric state measuring instrument for each track panel, obtain the measurement value of the corresponding adjustment point of the static geometric state measuring instrument for that track panel, calculate the deviation of the track panel at the adjustment point in terms of lateral direction, elevation, gauge and levelness based on the measurement value, and adjust the track panel at each corresponding adjustment point based on the deviation of the track panel at the adjustment point in terms of lateral direction, elevation, gauge and levelness.

[0128] Step 202: After the adjustment points corresponding to each track panel static geometry state measuring instrument are adjusted, each track panel static geometry state measuring instrument moves, so that the first track panel static geometry state measuring instrument moves to the next adjacent adjustment point of the track panel, and the second track panel static geometry state measuring instrument moves to the original position of the first track panel static geometry state measuring instrument, the third track panel static geometry state measuring instrument moves to the original position of the second track panel static geometry state measuring instrument, and so on, until the nth track panel static geometry state measuring instrument moves to the original position of the (n-1)th track panel static geometry state measuring instrument.

[0129] Step 203: Repeat steps 201 to 202 until all adjustment points of the track panel are adjusted.

[0130] In this embodiment, multiple track panel static geometric state measuring instruments are sequentially distributed along the track panel direction at several adjustment points on the track panel. This results in richer and more comprehensive data collection, improving the accuracy of track panel detection and fine-tuning. Furthermore, the data from the track panel static geometric state measuring instrument group can be fused, and the correlation between the data can be statistically analyzed to establish a mathematical model of the rigid body correlation of the track panel. Fine-tuning of the track panel based on this model can significantly improve the intelligence and adjustment accuracy of the track panel fine-tuning measurement, and is also beneficial for track panel design.

[0131] The detection method involves moving the nth track panel static geometric state measuring instrument to the original position of the (n-1)th track panel static geometric state measuring instrument. The nth track panel static geometric state measuring instrument can verify the (n-1)th adjustment point after fine adjustment. This improves the track panel fine adjustment accuracy and operational reliability while reducing subsequent verification steps, thereby improving operational efficiency.

[0132] Preferably, the total station has distance and angle measurement functions, and the method further includes determining the installation point of the total station, as follows:

[0133] More than 8 prisms 22 are set on the CPIII network of the line basic control network on both sides of the total station backsight line as CPIII backsight points of the total station. Based on the CPIII backsight points, the positional error of the CPIII backsight points and the center coordinate error of the total station are calculated through back intersection adjustment. Based on the positional error of the CPIII backsight points and the center coordinate error of the total station, the center coordinates of the total station and the azimuth value of the total station in the line coordinate system are calculated.

[0134] Based on the total station's center coordinates and azimuth value in the line coordinate system, calculate the mean square error of the total station's center coordinate components and the mean square error of the angle measurement. If the mean square error of the total station's center coordinate components is greater than 0.7 mm or the mean square error of the angle measurement is greater than 2", then reset the station and recalculate the mean square error of the total station's center coordinate components and the mean square error of the angle measurement until the total station's center coordinates and azimuth value corresponding to a mean square error of less than 0.7 mm and a mean square error of less than 2" are found. These are then used as the installation point for the total station, and the total station setup operation is performed.

[0135] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
