DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application 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 this application and are not intended to limit this application.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0037] Based on this, an embodiment of the present invention provides a rail vibration damping base and a rail vibration damper, which can provide excellent displacement control capability for the rail in the lateral direction.

[0038] like Figures 1 to 2 As shown, an embodiment of the present application provides a track vibration reduction base including a first mounting structure 1 and a second mounting structure 2. The second mounting structure 2 is provided on the first mounting structure 1; the second mounting structure 2 includes a fixing layer 21 and a first elastic layer 22. The first elastic layer 22 is inserted into the fixing layer 21 and is provided between the first mounting structure 1 and the fixing layer 21. The first mounting structure 1, the first elastic layer 22, and the fixing layer 21 are stacked in sequence. The fixing layer 21 is configured to limit the first elastic layer 22 along the X-axis and the Y-axis; wherein the X-axis and the Y-axis are perpendicular.

[0039] It should be noted that the X-axis above and below refers to the X-axis direction in the spatial coordinate system, that is, the lateral direction of the track vibration reduction base. Figure 1 The Y axis above and below refers to the Y axis direction in the spatial coordinate system, that is, the extension direction of the track. Figure 1 shown.

[0040] During the operation of the train, impact forces will be generated in the horizontal and vertical directions, that is, along the X-axis and Y-axis, and will act on the track buffer base through the track.

[0041] Specifically, when using the track vibration damping base, the impact force in the lateral direction acts on the first mounting structure 1 and the fixed layer 21 through the track. It should be noted here that the second mounting structure 2 is fixedly mounted on the outer rail sleeper. The fixed layer 21 can limit the first elastic layer 22 along the X-axis and Y-axis directions, so that the impact force in the lateral direction acts on the first elastic layer 22 through the fixed layer 21, and the first elastic layer 22 can buffer the impact force in the lateral direction. The impact force in the vertical direction acts on the first mounting structure 1 and the fixed layer 21 through the track. The first mounting structure 1, the first elastic layer 22 and the fixed layer 21 are stacked in sequence, and the first elastic layer 22 is arranged between the first mounting structure 1 and the fixed layer 21. The first elastic layer 22 can buffer the impact force in the vertical direction.

[0042] In the track vibration damping base provided in this application, the fixed layer 21 can limit the position of the first elastic layer 22 along the X-axis and Y-axis. The first elastic layer 22 can buffer impact forces in the lateral direction. Under the action of the fixed layer 21, when buffering lateral impacts, the first elastic layer 22 can be prevented from moving along the Y-axis, so that the first elastic layer 22 is always confined to the fixed layer 21. This prevents the first elastic layer 22 from escaping from between the first mounting structure 1 and the fixed layer 21 during the buffering process. The displacement and deformation of the first elastic layer 22 in the lateral direction are also small, which helps to improve the track vibration damping base's ability to control the displacement of the track in the lateral direction. In addition, the first elastic layer 22 can also buffer impact forces in the vertical direction, preventing damage from direct contact between the first mounting structure 1 and the fixed layer 21, which helps to increase the service life of the first mounting structure 1 and the fixed layer 21.

[0043] Optionally, the first elastic layer 22 is fixedly connected to the fixing layer 21 .

[0044] Specifically, the first elastic layer 22 is fixedly connected to the fixing layer 21 via an adhesive layer, or fixedly connected to the fixing layer 21 via vulcanization. It should be noted that vulcanization refers to a process of bonding iron and rubber together under high temperature and high pressure.

[0045] In this way, the first elastic layer 22 is fixedly connected to the fixed layer 21, which can also limit the first elastic layer 22 to the fixed layer 21, prevent the first elastic layer 22 from moving relative to the fixed layer 21, and thus prevent the first elastic layer 22 from escaping from between the first mounting structure 1 and the fixed layer 21, which helps to further improve the displacement control capability of the track vibration reduction base in the lateral direction.

[0046] Optionally, the first elastic layer 22 is made of a flexible material such as rubber or silicone.

[0047] In one embodiment of the present application, see Figure 1 and Figure 2 The fixed layer 21 has at least two first limiting portions (not shown), which are spaced apart along the X-axis and the Y-axis, respectively. The first elastic layer 22 has at least two second limiting portions 221, which are arranged in a one-to-one correspondence with the at least two first limiting portions and plugged into the first limiting portions. The fixed layer 21 has at least two third limiting portions (not shown), which are spaced apart along the X-axis and the Y-axis, respectively. The first elastic layer 22 has at least two fourth limiting portions 222, which are arranged in a one-to-one correspondence with the at least two third limiting portions and plugged into the third limiting portions.

[0048] It should be noted that this embodiment is described using the example of a fixed layer 21 having at least two first limiting portions and at least two third limiting portions, and a first elastic layer 22 having at least two second limiting portions 221 and a fourth limiting portion 222. Of course, in other embodiments, the fixed layer 21 may only have at least two first limiting portions, or the fixed layer 21 may only have at least two third limiting portions, the first elastic layer 22 may only have at least two second limiting portions 221, or the second elastic layer 23 may only have at least two fourth limiting portions 222. This is not intended to be a single limitation.

[0049] It should also be noted that this embodiment is described by taking as an example the case where the number of the first limiting portion, the second limiting portion 221, the third limiting portion, and the fourth limiting portion 222 is set to two. Of course, in other embodiments, the number of the first limiting portion, the second limiting portion 221, the third limiting portion, and the fourth limiting portion 222 can also be set to three, four, five, six, etc., and this is not a limitation.

[0050] In this embodiment, the shapes of the first limiting portion, the second limiting portion 221, the third limiting portion and the fourth limiting portion 222 on the cross section perpendicular to the Z axis are set to polygonal, elliptical, circular, irregular closed shape, etc.

[0051] Specifically, in this embodiment, the number of the first limiting portion, the second limiting portion 221, the third limiting portion, and the fourth limiting portion 222 is set to two. The two first limiting portions on the fixed layer 21 are positioned differently in the X-axis and Y-axis directions, and the two third limiting portions on the fixed layer 21 are also positioned differently in the X-axis and Y-axis directions. The two first limiting portions on the fixed layer 21 and the two third limiting portions on the first elastic layer 22 are plugged together, and the two second limiting portions 221 on the fixed layer 21 and the two fourth limiting portions 222 on the first elastic layer 22 are plugged together. Therefore, the fixed layer 21 can limit the first elastic layer 22 in two different directions.

[0052] With this arrangement, the fixing layer 21 can limit the first elastic layer 22 in the X-axis and Y-axis directions through the at least two first limiting portions and the at least two second limiting portions 221, thereby preventing the first elastic layer 22 from escaping from between the first mounting structure 1 and the fixing layer 21. Furthermore, the fixing layer 21 can further limit the first elastic layer 22 in the X-axis and Y-axis directions through the at least two third limiting portions and the at least two fourth limiting portions 222, thereby further improving the track vibration damping base's ability to control track displacement in the lateral direction.

[0053] In one embodiment of this application, please refer to Figure 1 、 Figure 2 and Figure 4 The first limiting portion has a plurality of first limiting walls (not shown in the figure), which are bent and connected in sequence and all extend along the Z axis. The second limiting portion 221 has a plurality of second limiting walls 2211, which are respectively arranged in a one-to-one correspondence with the plurality of first limiting walls and are configured to form a limit with the plurality of first limiting walls. The plurality of second limiting walls 2211 are all extended along the Z axis. The third limiting portion has a plurality of third limiting walls (not shown in the figure), which are bent and connected in sequence and all extend along the Z axis. The fourth limiting portion 222 has a plurality of fourth limiting walls 2221, which are respectively arranged in a one-to-one correspondence with the plurality of third limiting walls and are configured to form a limit with the plurality of third limiting walls. The plurality of fourth limiting walls 2221 are all extended along the Z axis.

[0054] It should be noted that the Z axis mentioned above and below refers to the Z axis direction in the spatial coordinate system, that is, the vertical direction of the track. Figure 1 shown.

[0055] It should also be noted that this embodiment is described using the example of a fixed layer 21 having both the first and third limiting walls, and the first elastic layer 22 having both the second limiting walls 2211 and the fourth limiting walls 2221. Of course, in other embodiments, the fixed layer 21 may have only the first limiting walls, or only the third limiting walls, the first elastic layer 22 may have only the second limiting walls 2211, or the second elastic layer 23 may have only the fourth limiting walls 2221. This is not intended to be a single limitation.

[0056] In this embodiment, the number of the first and second limiting walls 2211 is set to four, and the number of the third and fourth limiting walls 2221 is set to two. Of course, in other embodiments, the number of the first limiting wall, the second limiting wall 2211, the third limiting wall, and the fourth limiting wall 2221 can also be set to three, five, six, etc., and this is not a limit here.

[0057] When the number of the first limiting wall and the second limiting wall 2211 are both set to four, the shape of the first limiting portion and the second limiting portion 221 in the cross section perpendicular to the Z axis is a quadrilateral. When the number of the third limiting wall and the fourth limiting wall 2221 are both set to two, the third limiting portion and the fourth limiting portion 222 are grooves having two limiting walls and are in communication with the outside.

[0058] Specifically, when the device is in use, a lateral force acts on the first elastic layer 22 via the fixing layer 21 and the first mounting structure. This means that the lateral force acts on the second limiting wall 2211 via the first limiting wall and on the fourth limiting wall 2221 via the third limiting wall. This lateral force, also known as the force in the X-axis direction, is buffered by the second limiting wall 2211 against the impact force transmitted from the first limiting wall, while the fourth limiting wall 2221 buffers the impact force transmitted from the second limiting wall 2211. Thus, the impact force in the X-axis direction acts on the limiting walls extending along the Z-axis.

[0059] With this arrangement, the first, second, third, and fourth limiting walls 2211, 2221, and 2222 are all arranged along the Z-axis. This ensures that the extension direction of the first, second, third, and fourth limiting walls 2211, 2221 is perpendicular to the direction of the lateral impact force, that is, the X-axis is perpendicular to the Z-axis. Compared to related technologies, this helps improve the ability of the fixed layer 21 to limit the first elastic layer 22 in the lateral direction, thereby further improving the rail vibration damping base's ability to control the displacement of the rail in the lateral direction.

[0060] In one embodiment of the present application, see Figure 1 、 Figure 2 and Figure 4There are four first limiting walls, with each adjacent first limiting wall being perpendicular to each other. Two first limiting walls are spaced apart along the X-axis and parallel to the X-axis, while the other two first limiting walls are spaced apart along the Y-axis and parallel to the Y-axis. There are four second limiting walls 2211, with each adjacent second limiting walls 2211 being perpendicular to each other. Two second limiting walls 2211 are spaced apart along the X-axis and parallel to the X-axis, while the other two second limiting walls 2211 are spaced apart along the Y-axis and parallel to the Y-axis. There are two third limiting walls, with each adjacent third limiting wall being perpendicular to each other. One third limiting wall is parallel to the X-axis, while the other is parallel to the Y-axis. There are two fourth limiting walls 2221, with each adjacent fourth limiting wall 2221 being perpendicular to each other. One fourth limiting wall 2221 is parallel to the X-axis, while the other is parallel to the Y-axis.

[0061] In this arrangement, two first limiting walls are parallel to the X-axis, two other first limiting walls are parallel to the Y-axis, and the second limiting walls 2211 are arranged in a one-to-one correspondence. One third limiting wall is parallel to the X-axis, and another third limiting wall is parallel to the Y-axis. The fourth limiting walls 2221 are arranged in a one-to-one correspondence. Compared to related technologies, lateral impact forces can be perpendicular to the first limiting walls, second limiting walls 2211, third limiting walls, and fourth limiting walls 2221. This helps significantly improve the track vibration reduction base's ability to control track displacement in the lateral direction.

[0062] Optionally, the first limiting portion is configured as a concave portion, the second limiting portion 221 is configured as a convex portion, the third limiting portion is configured as a groove, and the fourth limiting portion 222 is configured as a bump.

[0063] With such arrangement, the first limiting portion can be plugged in and matched with the second limiting portion 221 , and the third limiting portion can be plugged in and matched with the fourth limiting portion 222 , and molding is facilitated.

[0064] In one embodiment of the present application, see Figure 1 、 Figure 2 and Figure 4 The first elastic layer 22 has at least two fifth limiting portions 223, and the at least two fifth limiting portions 223 are arranged along the Z axis through the first mounting structure 1, and are spaced apart along the X axis and the Y axis respectively; the fixed layer 21 has at least two connecting portions 211, and the connecting portions 211 are accommodated in the fifth limiting portions 223 and are arranged one-to-one with the fifth limiting portions 223.

[0065] It should be noted that this embodiment is described by taking the number of the fifth limiting portion 223 and the connecting portion 211 as two. Of course, in other embodiments, the fifth limiting portion 223 and the connecting portion 211 can also be set to three, four, five, six, etc., and this is not limited to any other number.

[0066] Specifically, when installing the track vibration damping base, first install the second mounting structure 2 to the outer rail sleeper, then removably connect the connector of the track vibration damping device to the connecting portion 211 to securely mount the track to the track vibration damping base. The connecting portion 211 extends along the Z axis and penetrates the first mounting structure 1, and is housed in the fifth position-limiting member. Therefore, lateral impact forces act on the fifth position-limiting member 223 and the fixed layer 21 through the connecting portion 211. The fifth position-limiting member 223 can buffer lateral impact forces transmitted through the connecting portion 211. Vertical impact forces act on the fixed layer 21 and the first elastic layer 22 through the connecting portion 211.

[0067] With this arrangement, the rail can be mounted to the side of the first mounting structure 1 facing away from the second mounting structure 2 via the connection portion 211. Furthermore, the connection portion 211 is received by the fifth stopper 223, which buffers lateral impact forces transmitted through the connection portion 211, preventing these impact forces from directly acting on the first mounting structure 1 through the connection portion 211, thereby improving the service life of the first mounting structure 1. At least two connection portions 211 are spaced apart along the X-axis and the Y-axis, and the fifth stopper 223 is provided in a one-to-one correspondence. Thus, the at least two connection portions 211 and the at least two fifth stoppers 223 can also restrain the first elastic layer 22 on the fixed layer 21 in different directions, further improving the rail vibration damping base's ability to control rail displacement in the lateral direction. Furthermore, the rail is mounted to the first mounting structure 1 via the connection portion 211, which extends along the Z-axis. During assembly, this does not increase the vertical stiffness of the first mounting structure 1, thereby extending the service life of the first mounting structure 1.

[0068] In one embodiment of this application, please refer to Figures 1 to 3 The second mounting structure 2 further includes a second elastic layer 23 , which is disposed on a side of the fixing layer 21 facing away from the first elastic layer 22 , and the fixing layer 21 is disposed in a space enclosed by the first elastic layer 22 and the second elastic layer 23 .

[0069] With this arrangement, after the first elastic layer 22 cushions impact forces in the lateral and vertical directions, the second elastic layer 23 can further cushion impact forces in the lateral and vertical directions, further enhancing the rail vibration damping base's cushioning effect. Furthermore, the first elastic layer 22, through the second elastic layer 23, completely envelops the fixing layer 21, preventing direct contact with the external environment and potentially increasing wear and tear on the fixing layer 21, thereby extending the service life of the fixing layer 21.

[0070] In one embodiment of the present application, see Figure 1、 Figure 2 、 Figure 5 and Figure 6 The track vibration reduction base includes a clamping structure 24, which is detachably clamped to the first mounting structure 1 and is configured to pass through the fixing layer 21 and the first elastic layer 22 to limit the fixing layer 21 and the first elastic layer 22 to the first mounting structure 1.

[0071] With this arrangement, the fixing layer 21 and the first elastic layer 22 can be detachably connected to the first mounting structure 1 via the snap-fit ​​structure 24. If any of the first mounting structure 1, the first elastic layer 22, or the fixing layer 21 is damaged, the fixing layer 21 and the first elastic layer 22 can be removed from the first mounting structure 1 for repair or replacement, thereby improving ease of use and reducing repair costs.

[0072] In one embodiment of the present application, see Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The clamping structure 24 includes a clamping cover 241 and a clamping body 242 connected to the clamping cover 241. The clamping body 242 is configured to be able to pass through the fixed layer 21 and the first elastic layer 22 so as to be detachably connected to the first mounting structure 1; the fixed layer 21 is provided with a limiting groove 212, and the clamping cover 241 is configured to be limited to the limiting groove 212 along the Z axis, and the fixed layer 21 and the first elastic layer 22 are locked to the first mounting structure 1 through the clamping body 242.

[0073] Specifically, when assembling the track vibration damping base, the second mounting structure 2 is first assembled onto the first mounting structure 1. The clamping body 242 passes through the fixing layer 21 and the first elastic layer 22 at one time and is then clamped onto the first mounting structure 1. The clamping cover 241 is then positioned within the limiting groove 212 and can limit the position of the fixing layer 21 and the first elastic layer 22 along the Z-axis.

[0074] With this arrangement, the clamping body 242 can be detachably connected to the first mounting structure 1. The clamping cover 241 can limit the position of the fixing layer 21 and the first elastic layer 22 along the Z-axis, preventing the fixing layer 21 and the first elastic layer 22 from falling out of the clamping body 242 after the clamping body 242 is installed on the first mounting structure 1. In this way, the second mounting structure 2 can be fixedly mounted to the first mounting structure 1, facilitating assembly and improving user convenience.

[0075] In one embodiment of this application, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6The first mounting structure 1 is provided with a plurality of first clamping portions 11 spaced apart in a circumferential direction around the Z axis; a plurality of second clamping portions 243 are spaced apart on the outer circumferential side of the clamping body 242, and the clamping body 242 is configured to be able to rotate around the Z axis so that the plurality of second clamping portions 243 are limited to the plurality of first clamping portions 11.

[0076] Specifically, when the clamping body 242 is mounted on the first mounting structure 1, the plurality of second clamping portions 243 on the clamping body 242 are aligned with the plurality of first clamping portions 11 on the first mounting structure 1. After alignment, the clamping body 242 is rotated to drive the plurality of second clamping portions 243 to rotate about the Z axis, so that the plurality of second clamping portions 243 are respectively engaged with the plurality of first clamping portions 11. When the clamping body 242 is removed from the first mounting structure 1, the clamping body 242 is rotated to drive the plurality of second clamping portions 243 to rotate about the Z axis, so that the plurality of second clamping portions 243 are offset from the plurality of first clamping portions 11, so that the first clamping portions 11 can release the restriction on the clamping body 242.

[0077] With this arrangement, the plurality of first engaging portions 11 can limit the engaging body 242 in the Z-axis direction via the plurality of second engaging portions 243, thereby locking the engaging body 242 to the first mounting structure 1. Furthermore, by rotating the engaging body 242, the engaging body 242 can be removed from the first mounting structure 1. In this way, the engaging body 242 can be detachably connected to the first mounting structure 1.

[0078] Optionally, the first clamping portion 11 is configured as an L-shaped clamping block, and the second clamping portion 243 is configured as an inverted L-shaped clamping block.

[0079] The present application also provides a track vibration damper, comprising a track vibration damping base and a connecting member, wherein the connecting member is detachably provided on the track vibration damping base and is configured to fix the track to the track vibration damping base.

[0080] The track vibration damper provided in this application utilizes a connector 211 to directly mount the track to the track vibration damping base, facilitating assembly and improving ease of use. Furthermore, the connector 211 can be directly connected to the fixing layer 21 without increasing the vertical stiffness of the first mounting structure 1, thereby increasing the service life of the track mounting base.

[0081] Optionally, the connecting piece is configured as a connecting fastener.

[0082] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
