[0034] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] Track fine-tuning is an important process before railway operation, which mainly involves the precise adjustment of track geometry to ensure that the track accuracy meets the standard and meets the requirements of fast, smooth and comfortable operation of high-speed trains. The quality of track fine-tuning has an important impact on the operation quality of EMUs and is directly related to the safety of high-speed rail operations.

[0036] The track row 9 to be adjusted is the double track for train operation, which needs to adjust the geometric state. Figure 3 As shown, the rail row 9 includes a first rail 91 and a second rail 92 arranged side by side, and a plurality of height fine-adjusting screws 93 are provided on the outer sides of the first rail 91 and the second rail 92, and a transverse fine-adjusting screw 94 is provided between the first rail 91 and the height fine-adjusting screws 93 on the outer sides thereof, and the transverse fine-adjusting device 4 is connected to the transverse fine-adjusting screw 94 and then rotates the transverse fine-adjusting screw 94 to adjust the transverse spacing between the first rail 91 and the second rail 92. The height fine-adjusting device 3 is connected to the height fine-adjusting screw 93 and then rotates the height fine-adjusting screw 93 to adjust the height of the first rail 91 and the second rail 92.

[0037] Since there is a bend in the rail row 9, the heights of the first rail 91 and the second rail 92 at the bend are inconsistent, resulting in the bottom support where the second rail 92 and the first rail 91 are located being tilted as a whole, tilting upward in the lateral direction from the first rail 91 to the second rail 92, and the lateral fine-tuning screw 94 connected to the rail for adjusting the spacing between the two rails will also be tilted, resulting in the lateral fine-tuning device 4 on the traditional fine-tuning machine not being able to dock with the lateral fine-tuning screw 94 smoothly, affecting the effect of adjusting the spacing of the rail row 9 after the lateral fine-tuning device 4 is docked with the lateral fine-tuning screw 94.

[0038] In view of this, refer to Figures 1 to 4As shown, this embodiment provides a fine-adjustment device suitable for adjusting different super-high sections of rails, including a crossbeam 14, a third longitudinal beam 13, a first connecting arm 61 and a second connecting arm 62. A second sleeve 17 is sleeved on the crossbeam 14, and the second sleeve 17 can slide along the length direction of the crossbeam 14. Exemplarily, the cross-section of the crossbeam 14 is rectangular, and the second sleeve 17 is a sleeve with a rectangular cross-section. The third longitudinal beam 13 is arranged to intersect with the crossbeam 14, and a transverse fine-adjustment device 4 is provided on the third longitudinal beam 13. The transverse fine-adjustment device 4 is used to dock with the transverse fine-adjustment screw 94 to form a rotational fit, thereby adjusting the transverse spacing between the first rail 91 and the second rail 92. The third longitudinal beam 13 can move along the length direction of the crossbeam 14 through the second sleeve 17 to adapt to the adjustment of the position of the transverse fine-adjustment device 4 on the third longitudinal beam 13, so as to dock with the transverse fine-adjustment screw 94.

[0039] The first connecting arm 61 is connected between the second sliding sleeve 17 and the third longitudinal beam 13, one end of the first connecting arm 61 is connected to the second sliding sleeve 17, and the other end of the first connecting arm 61 is hinged to the third longitudinal beam 13. One end of the second connecting arm 62 is connected to the second sliding sleeve 17, and a telescopic assembly 7 is provided between the other end of the second connecting arm 62 and the third longitudinal beam 13, and the two ends of the telescopic assembly 7 are respectively hinged to the other end of the second connecting arm 62 and the third longitudinal beam 13. When the telescopic assembly 7 is extended and retracted, the third longitudinal beam 13 can rotate around its own length direction as the central axis, and the transverse fine-adjustment device 4 will also rotate with the third longitudinal beam 13, so as to adapt to docking with the transverse fine-adjustment screw 94 inclined at the bend section.

[0040] The fine adjustment device for adjusting different super-high sections of rails provided in this embodiment is configured to support the transverse fine adjustment device 4 by providing a third longitudinal beam 13 connected to the transverse beam 14 and a transverse fine adjustment device 4 connected to the third longitudinal beam 13. The second sleeve 17 connected between the transverse beam 14 and the third longitudinal beam 13 is configured to drive the transverse fine adjustment device 4 to move along the length direction of the transverse beam 14 when the second sleeve 17 moves along the length direction of the transverse beam 14, thereby adjusting the position of the transverse fine adjustment device 4. The first connecting arm 61 and the second connecting arm 62 connected between the third longitudinal beam 13 and the second sleeve 17, and the telescopic assembly 7 connected between the second connecting arm 62 and the third longitudinal beam 13 are configured to enable the third longitudinal beam 13 to move along the length direction of the transverse beam 14 and also to rotate, thereby enabling the transverse fine adjustment device 4 to smoothly dock with the transverse fine adjustment screw 94 at the bend to form a rotational fit. After the lateral fine-adjusting device 4 is docked with the lateral fine-adjusting screw 94 , the lateral fine-adjusting screw 94 is rotated to adjust the lateral spacing between the first rail 91 and the second rail 92 .

[0041] In some embodiments, a plurality of transverse fine-adjustment devices 4 are provided on the third longitudinal beam 13, and the plurality of transverse fine-adjustment devices 4 are spaced apart along the length direction of the third longitudinal beam 13, so that the plurality of transverse fine-adjustment devices 4 can be docked with a plurality of transverse fine-adjustment screws 94 through posture adjustment of the third longitudinal beam 13, thereby completing the spacing adjustment of a section of rail row 9 at one time.

[0042] In some embodiments, the first connecting arm 61 and the second connecting arm 62 are distributed on the second sliding sleeve 17 along the length direction of the cross beam 14. When the telescopic assembly 7 connected between the second connecting arm 62 and the third longitudinal beam 13 is extended or retracted, the third longitudinal beam 13 can rotate around its own length direction as the axis. Reasonable use of space is made to avoid the first connecting arm 61 and the second connecting arm 62 occupying the longitudinal space.

[0043] In some embodiments, a driver 8 is provided between the second sliding sleeve 17 and the cross beam 14 , and the driver 8 is used to drive the second sliding sleeve 17 to slide along the cross beam 14 .

[0044] In some embodiments, the driver 8 is an electric telescopic rod, and bases are provided on the cross beam 14 and the second sliding sleeve 17. The fixed end of the electric telescopic rod is hinged to the base on the cross beam 14, and the movable end of the electric telescopic rod is hinged to the base on the second sliding sleeve 17. The telescopic direction of the electric telescopic rod is the length direction of the cross beam 14. Of course, the driver 8 can also be a driving member such as a cylinder or a hydraulic cylinder that can drive the second sliding sleeve 17 to slide along the cross beam 14.

[0045] In some embodiments, the fine adjustment device for adjusting different super-elevation rail sections also includes a first longitudinal beam 11 and a second longitudinal beam 12 arranged side by side in parallel, the first longitudinal beam 11 and the second longitudinal beam 12 are arranged to intersect with the cross beam 14, and the two ends of the cross beam 14 along its length direction are respectively connected to the first longitudinal beam 11 and the second longitudinal beam 12. A plurality of elevation fine adjustment devices 3 are arranged on the first longitudinal beam 11 and the second longitudinal beam 12, and the plurality of elevation fine adjustment devices 3 are distributed along the extension direction of the first longitudinal beam 11. After the elevation fine adjustment device 3 is connected to the elevation fine adjustment screw 93, the elevation fine adjustment screw 93 is rotated to adjust the height of the first rail 91 and the second rail 92.

[0046] like Figure 1 and Figure 3 As shown, in some embodiments, at least two cross beams 14 are provided, and at least two cross beams 14 are spaced apart along the length direction of the longitudinal beam, and a plurality of connecting beams 18 are provided between two adjacent cross beams 14. At least two cross beams 14 support the first longitudinal beam 11, the second longitudinal beam 12 and the third longitudinal beam 13 more stably.

[0047] In some embodiments, the first longitudinal beam 11 and the second longitudinal beam 12 are both provided with a lifting arm assembly 5, which can dock with the track and move along the length direction of the track. Alternatively, each cross beam 14 is provided with a lifting arm assembly 5 at both ends along its length direction, which can dock with the track and move along the length direction of the track. The cross beam 14, the first longitudinal beam 11, the second longitudinal beam 12 and the third longitudinal beam 13 can move along the length direction of the track through the lifting arm assembly 5.

[0048] In some embodiments, the lifting arm assembly 5 includes a roller 51 and a lifting arm 52 connected to the roller 51, the lifting arm 52 can be extended or shortened along a first direction, and the third longitudinal beam 13, the first longitudinal beam 11 and the second longitudinal beam 12 can move away from or close to the rail row 9 as the lifting arm 52 is extended or shortened, so as to facilitate the docking of the elevation fine-adjusting device 3 with the elevation fine-adjusting screw 93 and the docking of the lateral fine-adjusting device 4 with the lateral fine-adjusting screw 94.

[0049] In some embodiments, the track includes a first rail 91 and a second rail 92 arranged in parallel and side by side. The beam assembly 1 travels on the first rail 91 and the second rail 92 through the lifting arm assembly 5. Alternatively, the track includes a first rail 21 and a second rail 22 arranged in parallel and side by side, the first rail 21 and the second rail 22 are arranged on the fixing column of the height fine adjustment screw 93, and the first rail 21 and the second rail 22 are arranged in parallel and side by side. Avoid the beam assembly 1 from traveling directly on the first rail 91 and the second rail 92, thereby avoiding the first rail 91 and the second rail 92 from affecting their own fine adjustment height due to the load of the beam assembly 1.

[0050] In some embodiments, the cross beam 14 is bent along the middle of its length to form a U-shaped section 141. When the spacing between the first longitudinal beam 11 and the second longitudinal beam 12 in the length direction of the cross beam 14 changes slightly, the U-shaped section 141 can be deformed along the length direction of the cross beam 14 so that the length of the cross beam 14 changes, adapting to the change in the spacing between the first longitudinal beam 11 and the second longitudinal beam 12 in the length direction of the cross beam 14.
