In the present invention, some conventional operations and apparatuses, devices, components are omitted or only briefly described in order to highlight the importance of the present invention.
The invention provides a base plate 200 and a base plate 300 and a track based on the base plate, aiming at the problems in the laying track in the existing track traffic. The tie plate 200 and the tie plate 300 can satisfy the requirements for stability and prolonged service life of the rail.
Referring to fig. 1 to 4, the present embodiment provides a pad 200.
As shown in fig. 2, the tie plate 200 includes a body 100, a first rigidity providing group 206, and a second rigidity providing group 205.
The first stiffness providing group 206 and the second stiffness providing group 205 are both attached to the body 100. The first stiffness providing group 206 and the second stiffness providing group 205 are distributed dispersedly over a large part of the body 100 so that other external devices (rails) applying force form a large supporting surface.
Wherein the support surface may be formed by part or all of the first stiffness providing group 206 being in contact with an external device; the support surface may also be formed by all of the first stiffness providing group 206 and all or part of the second stiffness increasing group being in contact with an external device.
The first stiffness providing group 206 and the second stiffness providing group 205 may be provided in various forms to be able to provide different stiffness and to form a support for external devices.
In which, as shown in fig. 1, the body 100 is provided as a main structure of the pad 200. In laying the track, the pad 200 is installed between the steel rail and the concrete sleeper, and the body 100 may be contacted with the concrete sleeper. The body 100 may be made of an elastic material, such as rubber, resin, etc.; in other examples, the body 100 may be made of a rigid material, such as steel.
In the present embodiment, the body 100 is a flat plate having a plate surface larger than a thickness. The body 100 has a mounting surface 101 for mounting the first rigidity providing group 206 and the second rigidity providing group 205, and a side surface opposite to the mounting surface 101 serves as a surface for contact with other devices. In general, the mounting surface 101, the surface, and other parts of the body 100 are integrally formed. Optionally, the specific structure and shape of the body 100 can be selectively changed and adjusted according to the use scenario thereof. For example, in some special circumstances, the backing plate 200 may be configured as an arc-shaped plate, or may be configured as a plate with an arc-shaped groove.
In other embodiments, the body 100 may be made of multiple layers of different materials, for example, the body 100 is composed of a bottom layer, a middle layer and a surface layer which are sequentially stacked, and the mounting surface 101 is located on a side of the surface layer facing away from the middle layer. The bottom layer is made of rigid materials, the middle layer and the surface layer are made of elastic materials, and optionally the elasticity of the middle layer is smaller than that of the surface layer. Through selecting for use intermediate level and the surface course that has different elasticity for body 100 can provide more stable holding power when receiving external force, and the shrink deformation of body 100 is also littleer simultaneously. In other examples, it is possible to have different functional areas as a facing layer made of an elastic material, i.e. the facing layer is made up of elastic and non-elastic zones. Wherein the elastic zone provides shrinkage strain to absorb the extrusion acting force, and the inelastic zone can be used for keeping a relatively good appearance of the whole surface layer, so that the condition that the surface layer is damaged due to overlarge shrinkage strain is avoided.
The thickness of the body 100 may be selected according to a specific use scenario and its own material, so as to be able to bear external force and not be easily damaged. Similarly, the size of mounting surface 101 and the side opposite to mounting surface 101 may be adjusted and selected according to the specific application scenario and the material and thickness thereof.
Both the first stiffness providing group 206 and the second stiffness providing group 205 are provided in the form of a combined body. That is, both the first rigidity-providing group 206 and the second rigidity-providing group 205 have more rigidity-providing structures (elastic supports). By designing the first stiffness providing group 206 and the second stiffness providing group 205 as separate stiffness providing structures, it is advantageous to design for different structures, so that the cushion plate 200 has a more variable shape, and thus can be applied to a more complex environment. The shape of the first rigidity providing group 206 composed of a plurality of rigidity providing structures and the shape of the second rigidity providing group 205 composed of a plurality of rigidity providing structures may be the same or different, and the present invention is not particularly limited thereto. The first stiffness providing group 206 and the second stiffness providing group 205 may be part of a unitary structure or may be separate parts.
It should be understood that the first rigidity providing group 206 and the second rigidity providing group 205 are provided as different functional units, but both are provided together as a supporting member (rigidity providing element). In some use scenarios, the first stiffness providing group 206 and the second stiffness providing group 205 work together to provide support; in other usage scenarios, support may also be provided by only first stiffness providing group 206.
In this embodiment, the first stiffness providing group 206 has a plurality of first supports 202, the plurality of first supports 202 are distributed on substantially the entire mounting surface 101 of the body 100, and the first supports 202 are arranged at intervals. The distance reserved between the first supports 202 due to the spacing can be used for the second rigidity providing group 205, so that the second rigidity providing group 205 is fixed with the body 100.
The shape of the plurality of first supports 202 in the first stiffness providing group 206 may be the same or may be adjusted according to specific needs. In this embodiment, the first supporting members 202 are all the same in shape. The number of the first supports 202 constituting the first rigidity providing group 206 is mainly selected according to the use scene of the setting plate 200.
For example, when the first stiffness providing group 206 has a large contact surface with the external arrangement (rail), as one implementation, the contact surface of the individual first supports 202 with the rail is small, and the large contact surface is formed by the combination by providing enough first supports 202.
When the first stiffness providing group 206 has a smaller contact surface with the external arrangement (rail), as an implementation, the contact surface of the individual first supports 202 with the rail is large, whereas the smaller contact surface is formed by the combination by providing relatively fewer first supports 202. It will be appreciated that the number of second support members 201 and the particular dimensioning options for forming the second stiffness providing group 205 may also be designed in such a way as the second stiffness providing group 205 provides options.
Specifically, the first support 202 extends a first length from a first front end to a first rear end. The first support 202 is cylindrical, and in other examples, the first support 202 may also be prismatic. The diameter and height (first length) of the cylindrical first support 202 may be various sizes, and are selected according to the body 100, the use scenario, and the like.
The cylindrical first support 202 is connected to the body 100 in an upright manner, and specifically, the first support 202 is connected to the mounting surface 101 of the body 100 in an upright manner. That is, the first front end of the first support 202 is connected to the mounting surface 101, and the first rear end is away from the mounting surface 101. The first front end may be connected to the mounting surface 101 by clamping, or the first front end may be inserted into a hole formed in the mounting surface 101. In some examples, when the first support 202 has different portions such as an elastic portion and a rigid portion, and the rigid portion is made of metal, and the body 100 is also made of metal, the rigid portion of the first support 202 may be fixed to the mounting surface 101 of the body 100 by welding.
The distribution and arrangement of the plurality of first supporting members 202 constituting the first stiffness providing group 206 on the mounting surface 101 may be formed in a longitudinal and transverse manner, or may be formed in an array in a longitudinal and latitudinal manner. The two first supports 202 are preferably spaced apart to accommodate the second supports 201 arranged to form the second stiffness providing group 205. Of course, the arrangement of the plurality of first supporting members 202 may also be other shapes, for example, several first supporting members 202 are arranged in a circular manner, and a certain space is reserved around the center of the circle, so as to facilitate the arrangement of the second supporting member 201.
The second stiffness is provided with a plurality of second supports 201, and the stiffness of the second supports 201 is greater than the stiffness of the first supports 202. The second supporting member 201 is formed by extending a second length from the second front end to the second rear end, and the second length is smaller than the first length. Wherein the second front end is connected to the mounting surface 101 and the second rear end is remote from the mounting surface 101.
The second length being less than the first length means: the height of the second support 201 is less than the height in the first support frame, or the length in the second support frame is less than the length of the first support 202. The respective lengths of the second support 201 and the first support 202, and the relative length difference therebetween may be various specific values, and are selected according to the usage scenario of the cushion 200 and the material of the cushion 200, but the length in the second support frame is limited to be smaller than the length of the first support 202.
The arrangement and shape of the plurality of second supporting members 201 constituting the second stiffness providing group 205 on the mounting surface 101 of the body 100 may be selected according to specific situations, for example, when the plurality of first supporting members 202 constituting the first stiffness providing group 206 are arranged more closely, correspondingly, the plurality of second supporting members 201 are also arranged more closely, and vice versa.
As described above, the second rigidity providing group 205 and the first rigidity providing group 206 may be identical or different in structure and shape, and further, the first support 202 and the second support may be identical or different in shape and structure. For example, the first support 202 and the second support 201 are both prisms or cylinders. In some examples, the first support 202 is a cylinder and the second support 201 is a prism; alternatively, the second support 201 is a cylinder, and the first support 202 is a prism. Wherein, the prism body can be a triangular prism, a quadrangular prism or a pentagonal prism.
Further, the first support 202 and the second support 201 may also be circular truncated cones, an upper bottom surface (the end with the smaller diameter) of each circular truncated cone is far away from the mounting surface 101 of the body 100, and a lower bottom surface (the end with the larger diameter) of each circular truncated cone is connected with the mounting surface 101 of the body 100. The first support member 202 and the second support member 201 which are designed by adopting the structure have the advantages that a more stable supporting effect can be provided, and the first support member 202 and the second support member 201 can bear certain lateral impact force, so that the base plate 200 can be longer in service life and better in supporting effect.
It should be understood that the material of the first support member 202 and the second support member may be the same or different, for example, the first support member 202 and the second support member are made of rubber.
In some examples of the present invention, the first support 202 and the second support 201 are closely arranged, i.e., the first support 202 and the second support 201 are in contact with each other. For example, when the first support member 202 and the second support member 201 are both prism bodies, specifically, hexagonal prisms, the first support member 202 and the second support member 201 are arranged in close contact with each other, forming a structure having a honeycomb-shaped cross section.
In other examples, the first support 202 is spaced apart from the second support 201. There are various ways of spacing. For example, the plurality of second supports 201 constituting the second rigidity providing group 205 are relatively intensively located at one region of the mounting surface 101, and the plurality of first supports 202 constituting the first rigidity providing group 206 are relatively intensively located at another region of the mounting surface 101, and the one region is spaced apart from the another region by an appropriate distance. Alternatively, the first support members 202 and the second support members 201 are arranged at intervals in a staggered manner.
As one implementation, the plurality of first supports 202 are arranged in a row on the mounting surface 101 and form a plurality of spaced first support rows. The second supporting members 201 are arranged on the mounting surface 101 in rows and form a plurality of spaced second supporting rows, and at least one second supporting row is arranged between two adjacent first supporting rows.
As shown in fig. 3 and 4, in other examples (e.g., in the base plate 300), a plurality of first supporting members 208 and a plurality of second supporting members 207 form a plurality of supporting member groups 209 in a one-to-one correspondence manner, that is, one first supporting member 208 and one second supporting member 207 are combined to form one supporting member group 209, and the first stiffness providing group 206 and the second stiffness providing group 205 jointly form a plurality of supporting member groups 209.
In each support unit 209, the support unit 209 is composed of a first support member 208 and a second support member 207 coaxially and mutually sleeved, and the second support member 207 is sleeved outside the first support member 208. For example, when the first support 208 and the second support 207 are both cylindrical, the diameter of the second support 207 is larger than the diameter of the second support 207. The second supporting member 207 is provided with a through hole along the axial direction, one end of the first supporting member 208 extends into the through hole along the axial direction of the second supporting member 207, and the other end of the first supporting member 208 extends out of the first through hole along the axial direction of the second supporting member 207.
The embodiment also provides a rail based on the base plate 200. For example, the track includes tie plates 200, rails, and sleepers. The tie plate 200 is disposed between the rail and the crosstie, and the rail and the crosstie are connected. Further, the tie plate 200 may also be connected with a sleeper.
It should be noted that stiffness as used herein refers to the ability of a material or structure to resist elastic deformation when subjected to a force. The stiffness may be a static stiffness of the first support 202 and the second support 201 against deformation under a static load, or a dynamic stiffness of the first support 202 and the second support 201 against deformation under a dynamic load.
It should be noted that the structures providing different rigidities in the present invention are merely two structures, i.e., the first rigidity providing group 206 and the second rigidity providing group 205, by way of example. In other examples of the present invention, the number of structures providing different rigidities may also be three, i.e., the first rigidity providing group 206 and the second rigidity providing group 205, and the third rigidity providing group. Further, the structures providing different rigidities may also be three, i.e., the first rigidity providing group 206 and the second rigidity providing group 205, the third rigidity providing group, and the fourth rigidity providing group. In other words, the number of structures providing different rigidities in the mats provided in the present invention may be 2, 3, 4, 5, or even more, and the present invention is not limited to a specific number thereof.
As an alternative implementation, for example, the number of structures providing different rigidities is three, i.e., the first rigidity providing group 206 and the second rigidity providing group 205, and the third rigidity providing group. The three rigid structure groups are each formed by a plurality of columnar rods. Every 3 columnar rods are combined into a whole in a coaxial sleeving manner, and the 3 columnar rods combined into a whole are respectively provided by the first rigidity providing group 206, the second rigidity providing group 205 and the third rigidity providing group in a one-to-one correspondence manner. Further, the length of the columnar bar provided by the third stiffness group is greater than the length of the columnar bar provided by the second stiffness providing group 205, and the stiffness of the columnar bar provided by the third stiffness group is less than the stiffness of the columnar bar provided by the second stiffness providing group 205.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
