[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] In order to solve the technical problem in the prior art that the rails can only be placed on the corresponding positions of the pads according to the preset gauge, the gauge cannot be fine-tuned, and the practicality needs to be improved, the utility model provides a wooden sleeper fine-tuning pad assembly, which can fine-tune the distance between the rails and the stop seat according to the actual gauge requirements, and also enables the gauges of the two rails to be fine-adjusted to meet the actual gauge requirements. It has good practicality and can effectively prevent the rails from shifting sideways.

[0033] See also Figures 1 to 3 , Figures 1 to 3 This is a schematic structural diagram of a wooden sleeper fine-tuning pad 1 assembly in one embodiment of the present invention. The wooden sleeper fine-tuning pad 1 assembly includes a pad 1, two stoppers 3, and multiple groups of shims 4. The upper end surface of the pad 1 is provided with a support position 11 and two stoppers 12. The support position 11 is used to support the rail 2, and the stoppers 12 are provided on both sides of the support position 11. The two stoppers 3 are fixed to the upper end surface of the pad 1 and are respectively provided at the two stoppers 12, and each has a prefabricated gap 3a with the support position 11. Multiple groups of shims 4 can be selectively placed in the two prefabricated gaps 3a to abut against the rail 2 and the adjacent stoppers 3. It should be noted that when the gauge of the rail 2 is adjusted to the required gauge, multiple groups of shims 4 can be selectively placed in the two prefabricated gaps 3a, so that the shims 4 in each prefabricated gap 3a can abut against the rail 2 and the adjacent stoppers 3.

[0034] When the rail 2 is in the fixed position 11 and the distance between the rail 2 and the stopper 3 is adjusted, the space between the rail 2 and the stopper 3 is filled with gaskets 4 of corresponding thickness and quantity according to the adjusted distance between the rail 2 and the stopper 3, so that the rail 2, the gasket 4 and the stopper 3 abut against each other in turn, thereby preventing the rail 2 from moving sideways and ensuring the installation stability of the rail 2. In this way, the actual gauge requirement can be met and the practicality is good.

[0035] In one embodiment, the thicknesses of the gaskets 4 in the multiple groups are different.

[0036] In this embodiment, the thicknesses of the multiple groups of gaskets 4 are set to be different, and the gaskets 4 of different thicknesses are combined to further improve the accuracy of track gauge adjustment.

[0037] In one embodiment, each group of gaskets 4 is provided with a plurality of gaskets 4 , and the plurality of gaskets 4 in the same group can be selectively placed on a side of the stopper 3 close to the support position 11 .

[0038] In this embodiment, a plurality of gaskets 4 are provided in each group, and the gaskets 4 in each group are placed in the corresponding prefabricated gap 3a according to the required number, thereby improving the adaptability and practicality.

[0039] In one embodiment, the wooden sleeper fine-tuning pad 1 assembly further includes a locking structure 5 , which is provided on the pad 1 or the stop seat 3 and is used to limit the movement of the rail 2 relative to the pad 1 .

[0040] In this embodiment, after the gasket 4 cooperates to limit the lateral movement of the rail 2, the locking structure 5 can also limit the movement of the rail 2 relative to the base plate 1 along the track laying direction, further improving the installation stability of the rail 2.

[0041] In one embodiment, the locking structure 5 includes a locking plate 51, a locking bolt 52 and a locking nut 53. The locking plate 51 is provided with a connecting hole 51a. The locking bolt 52 extends in the vertical direction, and one end is fixed to the upper end surface of the base plate 1 and corresponds to the support position 11. The other end is passed through the connecting hole 51a. The locking nut 53 is screwed on the locking bolt 52 and is located on the side of the locking plate 51 away from the base plate 1, and limits the locking plate 51 to a position pressed against the rail 2.

[0042] In this embodiment, after the gasket 4 is placed, the connecting hole 51a of the locking plate 51 is aligned with the locking bolt 52, and then the locking plate 51 is moved in the direction close to the base of the rail 2 until the locking plate 51 is pressed against the base of the rail 2, and then the locking nut 53 is tightened so that the locking nut 53 limits the locking plate 51 to restrict the locking plate 51 from moving in the direction away from the base of the rail 2. The structure is simple and reliable, and the operation is convenient.

[0043] In one embodiment, see Figure 4 and Figure 5 An avoidance groove 3b is provided in the middle of the stop seat 3, and the locking bolt 52 is located in the avoidance groove 3b; the locking plate 51 includes a main plate 511 and a pressure plate 512, the main plate 511 is provided with a connecting hole 51a, and is placed on the upper end of the gasket 4, the pressure plate 512 is connected to the main plate 511, and is located on the side of the main plate 511 close to the pad 1, and is located on the side of the stop seat 3 close to the support position 11, for pressing against the rail 2.

[0044] In this embodiment, the locking bolt 52 is placed in the middle of the stop seat 3, and a corresponding avoidance groove 3b is provided to improve the compactness of the device. At the same time, the main plate 511 can also play a limiting role on the gasket 4 to limit the gasket 4 from escaping from the prefabricated gap 3a in the direction away from the pad 1, thereby improving the placement stability of the gasket 4.

[0045] In one embodiment, the locking plate 51 further includes a limiting plate 513 , which is connected to the main plate 511 and is located on a side of the main plate 511 close to the pad 1 and on a side of the blocking seat 3 away from the support position 11 .

[0046] In this embodiment, the limit plate 513 and the pressure plate 512 are clamped on both sides of the stop seat 3 in the horizontal direction, so as to effectively limit the circumferential displacement of the main plate 511 along the locking bolt 52 when the main plate 511 is installed, and ensure that the pressure plate 512 is always stably facing the base of the rail 2, thereby facilitating the pressing of the pressure plate 512 against the base of the rail 2.

[0047] In one embodiment, a pressing rib 514 is provided at one end of the pressing plate 512 away from the main plate 511 . The pressing rib 514 is inclined from one end close to the stopper 3 to one end away from the stopper 3 in a direction away from the pad 1 .

[0048] In this embodiment, the inclined pressing rib 514 is set in the above-mentioned form, so that the pressing rib 514 can not only stably press against the base of the rail 2, but also effectively limit the displacement of the base of the rail 2 in the direction close to the stop seat 3, thereby improving the installation stability of the rail 2.

[0049] In one embodiment, see Figure 6 A limiting groove 4a is concavely provided on the end surface of each gasket 4 close to the main plate 511, and the main plate 511 extends into the limiting groove 4a to limit the movement of the gasket 4 along the laying direction of the railway.

[0050] In this embodiment, when the pressure plate 512 is pressed against the base of the rail 2, the main plate 511 extends into the limit groove 4a of the gasket 4, which can limit the gasket 4 from accidentally deviating along the laying direction of the railway, ensuring that the gasket 4 is always in the prefabricated gap 3a, so that the rail 2, gasket 4 and the stop seat 3 are stably pressed against each other.

[0051] In one embodiment, see Figure 7 The communicating hole 51 a is extended along the arrangement direction of the supporting position 11 and the stopping position 12 .

[0052] In this embodiment, the connecting hole 51a extends horizontally. This allows the main plate 511 to be moved accordingly after the gasket 4 is positioned as needed, ensuring that the pressing plate 512 always presses against the base of the rail 2, improving practicality. It should be understood that in one embodiment, the gap between the limiting plate 513 and the pressing plate 512 is greater than the horizontal width of the stopper 3. Specifically, the horizontal direction refers to the layout direction of the support position 11 and the stopper 12, which is indicated by F in the accompanying drawings.

[0053] In order to better understand the present invention, the following Figures 1 to 7The technical solution of the utility model is described in detail:

[0054] In this solution, when the rail 2 is placed in the support position 11, a prefabricated gap 3a is left between the rail 2 and the stop seat 3, so that the rail 2 can be slightly moved according to actual conditions to fine-tune the distance between the rail 2 and the stop seat 3. When the track gauge is adjusted to the required gauge, the corresponding thickness and number of gaskets 4 are placed between the corresponding stop seat 3 and the rail 2 according to the actual distance between the rail 2 and the stop seat 3 to limit the lateral movement of the rail 2. Then, the connecting hole 51a of the main plate 511 is aligned with the locking bolt 52, and the pressing plate 512 is moved to a position pressing against the base of the rail 2. At this time, the main plate 511 extends into the limiting groove 4a of the gasket 4, and the locking nut 53 is screwed onto the locking bolt 52. The locking nut 53 is moved to a position pressing against the main plate 511, thereby limiting the main plate 511 to a position where the pressing plate 512 stably presses against the base of the rail 2, effectively preventing the rail 2 from moving relative to the pad 1.

[0055] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
