Description

Technical Field

[0001] The present application relates to the technical field of railway tracks, and in particular to a device for lateral fine adjustment of a track. Background Art

[0002] The track panel is a double-row track for trains to run on. There are curved sections in the track panel. Compared with the straight section of the track panel, the distance between the two tracks in the curved section is increased, resulting in a larger distance between the two elevation fine-tuning screws used to fine-tune the height of the two tracks.

Figure 2 As shown, the cross section of the cross beam 14 is rectangular, and the cross section of the first sleeve 16 is rectangular. The contact surface between the rectangular first sleeve 16 and the first longitudinal beam 11 is a rectangular surface, and the contact area is large and flat, so that the first longitudinal beam 11 is smooth and stable when slidingly connected with the cross beam 14 through the first sleeve 16.

[0041] In some embodiments, a driving assembly 7 is provided between the first longitudinal beam 11 and the cross beam 14, a first connecting portion 111 is provided on the first longitudinal beam 11 and between the two reinforcing ribs 18, a second connecting portion 141 is formed at the end of one end of the cross beam 14 away from the other end of the cross beam 14, and the driving assembly 7 is connected to the first connecting portion 111 and the second connecting portion 141 respectively. A first connecting portion 111 is provided between the two reinforcing ribs 18, and when the driving assembly 7 is working, after the first connecting portion 111 is subjected to force, the position on the first longitudinal beam 11 and between the two reinforcing ribs 18 connected to the first connecting portion 111 is not easily deformed, thereby avoiding the difficulty in docking the elevation fine-adjustment device 3 on the first longitudinal beam 11 with the elevation fine-adjustment screw 93 due to the deformation of the first longitudinal beam 11.

[0042] In some embodiments, the driving assembly 7 includes a rotating stud 71, a nut 72 and a connecting plate 73. The nut 72 is sleeved on the rotating stud 71 and forms a threaded fit with the rotating stud 71. The connecting plate 73 is connected between the nut 72 and the second connecting portion 141.

[0043] In some embodiments, Figure 2 As shown, the nut 72 has a welding surface 721 in the axial direction of the rotating stud 71, one end of the connecting plate 73 along the axial direction perpendicular to the rotating stud 71 is welded to the welding surface 721, and the other end of the connecting plate 73 is connected to the second connecting portion 141 by a fastener. The area of ​​the welding surface 721 of the nut 72 in the axial direction of the rotating stud 71 is the largest, so that the area of ​​the welding surface 721 of the nut 72 and the connecting plate 73 is the largest, thereby increasing the connection strength between the nut 72 and the connecting plate 73.

[0044] In some embodiments, the driving assembly 7 includes a telescopic rod (not shown in the figure), and the two ends of the telescopic rod are respectively connected to the first connecting portion 111 and the second connecting portion 141. The telescopic rod can be an electric telescopic rod, and the telescopic rod is extended to increase or decrease the distance between the first connecting portion 111 and the second connecting portion 141 in the length direction of the crossbeam 14. In specific implementation, one end of the connecting plate 73 is connected to the movable end of the telescopic rod, and the other end of the connecting plate 73 is connected to the second connecting portion 141 through a fastener. The other end of the telescopic rod is connected to the first connecting portion 111.

[0045] In some embodiments, the cross beam 14 is formed with a U-shaped section in the middle of its length direction. When the spacing between the first longitudinal beam 11 and the second longitudinal beam 12 in the length direction of the cross beam 14 needs to be slightly changed, the U-shaped section 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.

[0046] In some embodiments, the device for transverse fine adjustment of the rail row further includes a third longitudinal beam 13, the third longitudinal beam 13 is arranged in parallel with the first longitudinal beam 11, the third longitudinal beam 13 is connected to the transverse beam 14, and along the length direction of the transverse beam 14, the third longitudinal beam 13 is located between the U-shaped section and the first longitudinal beam 11. The third longitudinal beam 13 is provided with a transverse fine adjustment device 4, and the transverse fine adjustment device 4 is connected to the transverse fine adjustment screw 94.

[0047] like Figure 4 As shown, the beam assembly 1 includes a first longitudinal beam 11, a second longitudinal beam 12 and at least two cross beams 14, the first longitudinal beam 11 and the second longitudinal beam 12 are arranged in parallel and side by side, and the extension direction of the first longitudinal beam 11 intersects with the extension direction of the cross beam 14, each of the cross beams 14 is connected between the first longitudinal beam 11 and the second longitudinal beam 12, and the first longitudinal beam 11 and the second longitudinal beam 12 are both provided with the elevation fine-tuning device 3.

[0048] In some embodiments, the lateral fine-adjustment device 4 is provided in plurality, and the plurality of lateral fine-adjustment devices 4 are spaced apart along the length direction of the third longitudinal beam 13. The first longitudinal beam 11 is provided with a plurality of elevation fine-adjustment devices 3, and the plurality of elevation fine-adjustment devices 3 are spaced apart along the length direction of the first longitudinal beam 11. The second longitudinal beam 12 is provided with a plurality of elevation fine-adjustment devices 3, and the plurality of elevation fine-adjustment devices 3 are spaced apart along the length direction of the second longitudinal beam 12.

[0049] The first longitudinal beam 11 is arranged in parallel with the first running rail 21, and the first longitudinal beam 11 and the second longitudinal beam 12 are arranged one by one with the first running rail 21 and the second running rail 22. The lifting arm assembly 5 drives the first longitudinal beam 11 to run on the first running rail 21 along the extension direction of the adjusted rail row 9 through the cross beam 14, and the height of the lifting arm assembly 5 itself can be adjusted, so that the lifting arm assembly 5 adjusts the height of the first longitudinal beam 11 through the cross beam 14, that is, adjusts the elevation fine adjustment device 3 to move toward or away from the elevation fine adjustment screw 93, and the elevation fine adjustment screw 93 is connected or disconnected with the elevation fine adjustment device 3. When the elevation fine adjustment screw 93 is connected with the elevation fine adjustment device 3, the geometric state (height) of the rail row 9 is adjusted. After the adjustment is completed, the elevation fine adjustment screw 93 is disconnected from the elevation fine adjustment device 3, and the lifting arm assembly 5 continues to move until the elevation fine adjustment device 3 is docked with the next set of elevation fine adjustment screws 93, thereby adjusting the next section of the rail row 9. Each time the beam assembly 1 moves to a position and stops, the plurality of elevation fine-adjusting devices 3 on the first longitudinal beam 11 are docked with a group of elevation fine-adjusting screws 93 .

[0050] In some embodiments, there are multiple cross beams, which are spaced apart along the length direction of the first longitudinal beam, and a connecting beam is connected between two adjacent cross beams. The multiple cross beams are respectively connected to various parts of the first longitudinal beam in the length direction, so that the first longitudinal beam is more stable.
