Abstract
Description
Technical Field
[0001] This invention relates to the field of track construction technology, and in particular to a track fine-tuning device and method. Background Technology
[0002] Ballastless track refers to a track structure that uses a monolithic foundation of concrete, asphalt mixture, etc., instead of loose gravel ballast. Compared to ballasted track, ballastless track avoids ballast splashing, offers better smoothness, stability, service life, durability, and requires less maintenance. Train speeds can reach over 350 km / h. Currently, ballastless track construction typically employs the track panel method. The track panels are reinforced and fine-tuned using specialized equipment, either by jacking or bracing. This involves installing the track panel after the ballast slab formwork is installed, followed by coarse and fine adjustments. Fine-tuning requires calibration using a total station or other specialized instruments. After fine-tuning, concrete is quickly poured until the track panel is fully formed.
[0003] In the disclosed technology, two support mechanisms are spaced apart, with the two ends of a crossbeam mounted on the top supports of the two support mechanisms. The two ends of a connecting rod are connected to the supports of the two support mechanisms. A rail support adjustment mechanism is mounted on the crossbeam to fix and adjust the rail. The support plate can be raised and lowered, thus adjusting the height of the rail. The rail support adjustment mechanism can adjust the position of the rail. When using this equipment for adjustment, the height and lateral adjustments of the rail panel are performed completely independently. It is difficult to ensure that the rail panel is adjusted to the correct position during each adjustment process, requiring multiple adjustments, resulting in low work efficiency. Furthermore, for large-sized and heavy rail panels, this adjustment method may pose certain safety hazards and requires further improvement. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides a track fine-tuning device, including a connecting arm for supporting and positioning the track panel, a connecting seat connected to the connecting arm, and an adjustment mechanism connected to the connecting seat and used to drive the connecting seat to move. Multiple adjustment mechanisms are arranged on both sides of the track panel, and the adjustment mechanisms can adjust multiple degrees of freedom of the connecting seat; The adjustment mechanism includes an adjustment base, a first lead screw assembly, a second lead screw assembly, and a connecting rod assembly. The adjustment base is disposed on a support surface. The first lead screw assembly and the second lead screw assembly are both disposed on the adjustment base. The first lead screw assembly and the second lead screw assembly are both arranged along the height direction and are both connected to the connecting seat through the connecting rod assembly.
[0006] Furthermore, the connecting arm is provided with two limiting grooves, which match the cross-sectional shape of the rail. The distance between the two limiting grooves is consistent with the standard spacing of the rail. The limiting groove is also provided with locking bolts and buffer pads. The locking bolts are used to lock the rail in the limiting groove, and the buffer pads are used to compensate for gaps and buffer.
[0007] Furthermore, both the connecting seat and the connecting arm have bolt holes at their ends, and the connecting seat and the connecting arm are connected by connecting bolts.
[0008] Furthermore, the first lead screw assembly includes a first lead screw, a first movable seat, and a first drive unit. The first lead screw is arranged along the height direction and is rotatably connected to the adjusting base. The first movable seat is threadedly engaged with the first lead screw, and the first drive unit is used to drive the first lead screw to rotate. The second lead screw assembly includes a second lead screw, a second movable seat, and a second drive unit. The second lead screw is arranged along the height direction and is rotatably connected to the adjusting base. The second movable seat is threadedly engaged with the second lead screw, and the second drive unit is used to drive the second lead screw to rotate.
[0009] Furthermore, the linkage assembly includes a first link, a second link, and a third link. The third link has a first end, a middle end, and a second end. The second end of the third link is fixedly connected to the connecting seat. The first end of the third link is rotatably connected to the second end of the first link. The first end of the first link is rotatably connected to the first movable seat. The middle end of the third link is rotatably connected to the second end of the second link. The first end of the second link is rotatably connected to the second movable seat.
[0010] Furthermore, a first tilt sensor is provided on the first connecting rod, and a second tilt sensor is provided on the second connecting rod.
[0011] Furthermore, the tilt angles of the first and second connecting rods are detected by the first tilt sensor and the second tilt sensor, and the height positions of the first and second movable seats are obtained by the first lead screw and the second lead screw, respectively, in order to calculate the state of the connecting arm.
[0012] Furthermore, for a standard track panel, three sets of the aforementioned adjustment mechanisms are provided on each side of the track panel.
[0013] The present invention also provides a track fine-tuning method, which uses a track fine-tuning device as described above, and includes the following steps: S1, Install multiple adjustment mechanisms in preset positions, connect them to the connecting arm via connecting seats, and position and fix the rail panel and the connecting arm; S2, the system confirms the tilt angle of the track panel relative to the Y-axis and the height at different X-axis positions; S3, the system calculates the state that the adjustment mechanism needs to adjust, including the height of the first movable seats on both sides. h 11 , h 12 The height of the second movable seat h 21 , h 22 The angle between the first connecting rods on both sides and the first lead screw , The angle of the second connecting rod relative to the second lead screw , ; S4, the first drive motor and the second drive motor of the adjustment mechanism drive the first lead screw and the second lead screw to rotate respectively, so that the first movable seat and the second movable seat move to the height position in S3.

Detailed Implementation
[0019] To make the technical problems, solutions, and advantages of this invention clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0020] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] like Figure 1As shown, an embodiment of the present invention provides a track fine-tuning device, including a connecting arm 10 for supporting and positioning the track panel, a connecting seat 20 connected to the connecting arm 10, and an adjustment mechanism 30 connected to the connecting seat 20 and used to drive the movement of the connecting seat 20. Considering that the track panel 40 is usually prefabricated as a whole, and its size and weight are relatively large, in this embodiment, the connecting arm 10 is set to span the entire track panel 40, and both ends of the connecting arm 10 are respectively connected to a connecting seat 20. The connecting seat 20 is then connected to the corresponding adjustment mechanism 30. The adjustment mechanism 30 is set on the support surface at the construction site, such as on the roadbed, bridge, tunnel, etc., thereby supporting the track panel 40 and completing the horizontal (or other preset posture) adjustment under the action of the adjustment mechanism 30.
[0023] At the same time, such as Figure 2 As shown, considering that the two rails in the track panel 40 are usually already arranged, in this embodiment, a limiting groove 11 is further provided on the connecting arm 10. The limiting groove 11 matches the cross-sectional shape of the rail so that the rail can be placed in the limiting groove 11, and the rail is laterally positioned by the laterally arranged connecting arm 10. Since the distance between the two limiting grooves 11 is consistent with the standard spacing of the rails, the standard spacing between the rails can be ensured by the limiting groove 11 during construction. At the same time, the limiting groove 11 is also provided with a locking bolt 12 and a buffer pad 13. The locking bolt 12 locks the part of the rail in the limiting groove 11, and the buffer pad 13 compensates for the gap and avoids damage to the rail by hard force.
[0024] In this embodiment, bolt holes are provided at the ends of both the connecting seat 20 and the connecting arm 10. The connecting seat 20 and the connecting arm 10 are connected as one unit by the connecting bolts 21 to prevent them from loosening and shifting relative to each other during adjustment. Of course, considering the conditions of the construction site, the connecting arm 10 can also be further provided with an extension. The two ends of the extension are connected to the connecting arm 10 and the connecting seat 20 by the connecting bolts 21 to further improve the flexibility of on-site adjustment.
[0025] At the same time, such as Figure 3 As shown, in this embodiment, the adjustment mechanism 30 is used to adjust multiple degrees of freedom of the connecting seat 20, including height (Z-axis position), lateral position (Y-axis position), and tilt angle. It should be noted that in this embodiment, the X, Y, and Z directions are as follows: Figure 1 As shown, the X direction corresponds to the orientation of the rail, the Y direction corresponds to the orientation of the sleeper, and the Z direction corresponds to the height direction.
[0026] Understandably, for a standard length rail panel 40, multiple connecting seats 20 and adjusting mechanisms 30 need to be installed on both sides of the rail panel 40 to adjust the support points of the rail panel 40 (i.e., the positions where the limiting grooves 11 support the rails). Ideally, for example, when adjusting the rail panel 40 to be level, it is only necessary to adjust the height of each connecting seat 20 to be consistent, ensure that the lateral positions of the connecting seats 20 on the same side of the rail panel 40 are consistent, and ensure that the connecting seats 20 are not tilted relative to the XY plane, thus ensuring that the rail panel 40 is level. However, in the actual adjustment process, due to the large size and weight of the rail panel 40, deformation of the rail panel 40 itself, deformation of the connecting arm 10, and the accuracy of the adjusting mechanism 30, it is difficult to achieve the above ideal situation. Therefore, in the actual adjustment process, each connecting seat 20 needs to be adjusted and corrected multiple times until the total station or other specialized instruments detect that the position, tilt angle, etc. of the rail panel 40 meet the requirements. In this embodiment, by adjusting the above three degrees of freedom of the connecting seats 20, it can be ensured that the rail panel 40 is finally adjusted to meet the requirements.
[0027] In a preferred embodiment of this invention, the adjustment mechanism 30 includes an adjustment base 31, a first lead screw assembly, a second lead screw assembly, and a connecting rod assembly. The adjustment base 31 is disposed on a support surface to support the entire adjustment mechanism 30 and bear the forces transmitted by the track panel 40, connecting arm 10, etc. Both the first and second lead screw assemblies are disposed on the adjustment base 31 and are connected to the connecting seat 20 via the connecting rod assembly to adjust the aforementioned three degrees of freedom of the connecting seat 20. By arranging the connecting rod assembly so that both the first and second lead screw assemblies are along the Z-direction, the height, lateral position, and tilt angle of the connecting seat can be adjusted. This arrangement makes the adjustment mechanism 30 more compact overall, with a relatively large size only in the height direction, avoiding the occupation of a large area of the roadbed, bridge, tunnel, or other support surfaces, thus facilitating its placement.
[0028] To achieve the above-mentioned method, the first lead screw assembly in this embodiment includes a first lead screw 32, a first movable seat 33, and a first drive unit. The first lead screw 32 is arranged along the Z-direction, and the first movable seat 33 is threadedly engaged with the first lead screw 32 so that the first movable seat 33 can move along the Z-direction when the first lead screw 32 rotates. The first end of the first lead screw 32 is rotatably connected to the adjusting base 31. The first drive unit includes a first drive motor and a first transmission structure. The first transmission structure can be in the form of a synchronous belt, etc. The output end of the first drive motor is connected to the first lead screw 32 through the first transmission structure, thereby driving the first lead screw 32 to rotate. Since fine-tuning of the track panel 40 is required, the first drive motor needs to be a high-precision motor. The second lead screw assembly includes a second lead screw 34, a second movable seat 35, and a second drive unit. The second lead screw 34 is arranged along the Z-direction, and the second movable seat 35 is threadedly engaged with the second lead screw 34 so that the second movable seat 35 can move along the Z-direction when the second lead screw 34 rotates. The first end of the second lead screw 34 is also rotatably connected to the adjusting base 31. The second drive unit includes a second drive motor and a second transmission structure. The second transmission structure can also be in the form of a synchronous belt. The output end of the second drive motor is connected to the second lead screw 34 through the second transmission structure, thereby driving the second lead screw 34 to rotate. The second drive motor is also a high-precision motor.
[0029] At the same time, such as Figure 4 As shown, the linkage assembly includes a first link 36, a second link 37, and a third link 38. The third link 38 has a first end, a middle end, and a second end. The second end of the third link 38 is fixedly connected to the connecting seat 20. The first end of the third link 38 is rotatably connected to the second end of the first link 36. The first end of the first link 36 is rotatably connected to the first movable seat 33. The middle end of the third link 38 is rotatably connected to the second end of the second link 37. The first end of the second link 37 is rotatably connected to the second movable seat 35. Therefore, when the first movable seat 33 and the second movable seat 35 move synchronously in the Z direction, the posture of the entire linkage assembly can remain unchanged, allowing the connecting seat 20 to move along the Z direction to adjust the height. When the distance the first movable seat 33 moves along the Z direction is greater than (or less than) the distance the second movable seat 35 moves along the Z direction, since the lengths of the first link 36 and the second link 37 do not change, the second end of the third link 38 will rotate relative to the middle end, thereby changing the posture of the entire third link 38 and achieving the purpose of adjusting the tilt angle of the connecting seat 20. When the first movable seat 33 and the second movable seat 35 move in opposite directions, the first link 36 and the second link 37 rotate clockwise and counterclockwise respectively, thereby causing the third link 38 to move along the Y direction and adjusting the lateral position.
[0030] It should be noted that this linkage assembly design causes a certain horizontal displacement of the connecting seat 20 when its tilt angle is adjusted. Therefore, the above process is carried out comprehensively during actual adjustment. By controlling the first and second drive motors, when the first movable seat 33 and the second movable seat 35 are in preset positions, the different degrees of freedom of the connecting seat 20 can all reach preset values, completing the track fine-tuning. Furthermore, this dual-motor approach, which adjusts at least three degrees of freedom, simplifies motor usage costs and improves reliability.
[0031] Please also refer to Figure 5 , Figure 5 In this diagram, the midline segment RK represents the first link 36, KM represents the portion between the first and middle ends of the third link 38, SM represents the second link 37, and AF and BG represent the directions in which the first lead screw 32 and the second lead screw 34 drive the first movable seat 33 and the second movable seat 35, respectively. The other side (O, P, Q, N, C, D, I, H) is similar. Therefore, without considering the deformation of the connecting arm 10, i.e., MN remaining straight, it is only necessary to obtain the height positions of R, S, P, and Q, and the angle of RK relative to AF. SM from the perspective of BG The angle of PO relative to DH QN relative to CI This allows us to obtain the center position of MN and its angle relative to the Y-axis, thereby adjusting the rail 40 supported by the connecting arm 10.
[0032] Based on this, in this embodiment, a first tilt sensor is further provided on the first connecting rod 36 and a second tilt sensor is provided on the second connecting rod 37. The first tilt sensor and the second tilt sensor can detect the tilt angles of the first connecting rod 36 and the second connecting rod 37, respectively. The height positions of R, S, P and Q are directly determined by the corresponding lead screw assembly, thereby enabling accurate adjustment of the corresponding positions of the track panel 40.
[0033] For example, in this embodiment, for a standard track panel 40, three sets of adjustment mechanisms 30 are provided on each side, that is, a total of six sets of adjustment mechanisms 30 are used for adjustment. At different X-axis positions, the two adjustment mechanisms 30 on both sides are used to adjust the position of the track panel 40 to the correct position. Then, at different X-axis positions, height differential adjustments can be made to tilt the track panel 40 along the X direction to meet actual construction requirements. In addition, for slight deformations of the track panel 40, connecting arm 10, etc., each adjustment mechanism 30 needs to make certain independent fine adjustments to ensure that the track panel 40 ultimately meets the requirements.
[0034] It should also be noted that the lead screw assembly of the adjustment mechanism 30 can be replaced with other types of linear drive mechanisms, as long as the corresponding linear drive mechanism is high precision.
[0035] Based on the same inventive concept, this embodiment also provides a track fine-tuning method, which uses the aforementioned track fine-tuning equipment and specifically includes the following steps: S1, Install multiple adjustment mechanisms 30 in preset positions, connect them to the connecting arm 10 through the connecting seat 20, and position and fix the rail panel 40 to the connecting arm 10; S2, the system confirms the tilt angle of track panel 40 relative to the Y-axis and the height at different X-axis positions; S3, the system calculates the state that the adjustment mechanism 30 needs to adjust, including the height of the first movable seats 33 on both sides. h 11 , h 12 The height of the second movable seat is 35. h 21 , h 22 The angle between the first connecting rods 36 on both sides and the first lead screw 32 , The angle of the second connecting rod 37 relative to the second lead screw 34 , ; In S4, the first drive motor and the second drive motor of the adjusting mechanism 30 drive the first lead screw 32 and the second lead screw 34 to rotate, so that the first movable seat 33 and the second movable seat 35 move to the height position in S3. At this time, the angles of the first connecting rod 36 and the second connecting rod 37 also reach the calculated value in S3, thus completing the fine adjustment of the track panel 40.
[0036] Among them, the objective function of track panel adjustment F It can be represented as follows:
[0037] in, This indicates the height of the center of track panel 40. This indicates the lateral position of the center of track panel 40. This indicates the angle of track panel 40 relative to the Y-axis; It should be noted that when the height of different X-axis positions of the track panel 40 needs to be set differently, the height of all X-axis positions can be adjusted to be the same first, and then the adjustment mechanisms 30 on both sides of different X-axis positions can be raised synchronously to achieve the purpose of adjusting the track panel 40 to tilt at a preset angle relative to the X-axis.
[0038] It is worth mentioning that, because the adjustment mechanism 30 has multiple components on both sides of the X-axis, for example... Figure 1As shown, all six adjustment mechanisms 30 on both sides can be adjusted to an initial state during actual testing. This initial state is close to the target state and can be adjusted based on experience. Then, the adjustment mechanism 30 in the middle position (relative to the X-axis) is used as a limiting mechanism, mainly for supporting and limiting the track panel 40. It is generally not fine-tuned during the adjustment process, while the adjustment mechanisms 30 at both ends (relative to the X-axis) are fine-tuned. Actual testing has shown that this ensures that the track panel 40 is adjusted to the target state more smoothly and efficiently.
[0039] In summary, the track precision bar equipment and method provided in this embodiment, through the setting of multiple adjustment mechanisms 30 on both sides, enable the track panel 40 to be automatically, efficiently, and accurately adjusted to the target state, ensuring efficient and reliable on-site construction. The adjustment mechanism 30 is driven by two sets of lead screw assemblies arranged in the height direction. Compared with the solution that requires lateral drive, it can better complete the adjustment of the height, lateral position, and tilt angle of the track panel 40, and simplifies the structural form and the number of motors used, making it convenient for on-site layout and operation.
[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
