There is first provided in the present example embodiment a rail brace, as illustrated in fig. 1, 2 and 3, which may include: bottom plate 101, riser 103, elastic layer 104 and fagging 105. A through mounting groove 102 is formed in the middle of the bottom plate 101; the vertical plate 103 is vertically connected with the bottom plate 101 and extends from the first edge of the bottom plate 101 to a direction away from the first surface of the bottom plate 101; the elastic layer 104 is disposed on the outer vertical surface of the vertical plate 103 and extends to the connection between the vertical plate 103 and the base plate 101, and includes a first elastic layer 1041 and a second elastic layer 1042, the first elastic layer 1041 is disposed on one side close to the vertical plate 103, the second elastic layer 1042 contacts with the rail 200, and the stiffness of the first elastic layer 1041 is greater than that of the second elastic layer 1042; the supporting plate 105 is vertically connected with the bottom plate 101 and extends from the second edge of the bottom plate 101 to a direction away from the second surface of the bottom plate 101; wherein the first edge is disposed opposite the second edge, and the first face is disposed opposite the second face.
Specifically, the rail brace may include a bottom plate 101, a vertical plate 103, an elastic layer 104 and a supporting plate 105, the vertical plate 103 is vertically disposed on a first side of the bottom plate 101, the supporting plate 105 is vertically disposed on a second side of the second surface of the bottom plate 101, wherein the first side and the second side are two opposite sides of the bottom plate 101, the vertical plate 103 and the supporting plate 105 may be integrally formed, and the integrally forming process enables the rail brace to have better support performance due to better integrity. Illustratively, the bottom plate 101 is a rectangular plate, and the first side and the second side are two sides of the rectangular bottom plate 101 parallel to each other, and a combined structure with a Z-shaped cross section is formed by the arrangement of the standing plate 103 and the supporting plate 105. An elastic layer 104 is disposed on the outer vertical surface of the vertical plate 103, the elastic layer 104 can be attached to the outer vertical surface of the vertical plate 103 by a vulcanization method or an adhesion method, and of course, the elastic layer 104 can also be attached to the outer vertical surface of the vertical plate 103 by other processes. The elastic layer 104 is composed of a first elastic layer 1041 and a second elastic layer 1042, the first elastic layer 1041 is close to one side of the riser 103, the second elastic layer is in contact with the rail 200, and the rigidity of the first elastic layer 1041 is greater than that of the second elastic layer 1042. Under the design, the second elastic layer 1042 is made of a high-elasticity low-rigidity material and plays a role in vibration reduction and noise reduction of the rail 200, the first elastic layer 1041 is high in rigidity and can play a role in limiting compression of the second elastic layer 1042, when the compression deformation amount of the second elastic layer 1042 reaches a certain value, the first elastic layer 1041 bears load, the compression deformation of the second elastic layer 1042 is controlled to a certain extent, and the problems of deflection, eversion and the like of the rail 200 caused by excessive deformation of the second elastic layer 1042 are avoided as much as possible.
For example, the first elastic layer 1041 and the second elastic layer 1042 may be integrally formed, and the first elastic layer 1041 may be a whole layer disposed on one side of the riser 103, or may be partially disposed on the riser 103. When the first elastic layer 1041 is partially disposed on one side of the vertical plate 103, as shown in fig. 1, a plurality of first elastic layers 1041 are disposed on the vertical plate 103 in a partitioned manner, and the second elastic layer 1042 is disposed on the first elastic layer 1041 in a covering manner, so that the second elastic layer 1042 is a whole layer; as shown in fig. 2, a plurality of first elastic layers 1041 may be disposed on the riser 103 in a partitioned manner, a second elastic layer 1042 is disposed at a gap portion of the plurality of first elastic layers 1041 on the riser 103, the second elastic layer 1042 contacts with the rail 200, and the first elastic layer 1041 has a predetermined distance from the rail 200, where the predetermined distance may be a reasonable compression deformation amount of the second elastic layer 1042 relative to the rail 200. The specific setting area, thickness and number of the first elastic layer 1041 are related to the speed and axle weight of the train passing through the track 200; the second elastic layer 1042 may be made of rubber, epdm, polyurethane, or other elastic materials.
When the rail brace is assembled for use, the elastic layer 104 on the outer vertical surface of the vertical plate 103 of the rail brace is closely attached to the transverse outer side of the rail 200, so that a certain supporting effect is achieved on the rail 200, and the thickness of the minimum thickness part of the elastic layer 104 is 2-15 mm. The rail brace is mounted to a pad under the rail 200 by means of a mounting slot 102 in the base plate 101. The free end of the supporting plate 105 of the rail brace is contacted with the backing plate to support the bottom plate 101.
The rail brace is tightly attached to the rail 200 after being assembled through the arrangement of the elastic layer 104, so that on one hand, the transverse rigidity of the rail 200 is better enhanced, and the problems of abrasion and safety caused by the fact that the rail 200 is tilted outwards due to insufficient rigidity are solved, on the other hand, vibration energy generated by a train passing through the rail 200 in real time is converted into heat energy of the elastic layer 104 to be dissipated, a certain damping function is achieved, and vibration noise of a wheel rail is reduced; further, the elastic layer 104 is formed by a first elastic layer 1041 and a second elastic layer 1042 with different elasticity, and the first elastic layer 1041 with higher rigidity can support and limit the second elastic layer 1042 with lower rigidity, so as to prevent the second elastic layer from being seriously deformed to a certain extent, and make the outward expansion amount of the track 200 within a reasonable design range as much as possible.
Next, each part of the above-described rail brace in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 12.
In one embodiment, referring to fig. 1 or 2, at least one embedding groove is formed on the outer vertical surface of the vertical plate 103, and at least one embedding protrusion is formed on the surface of the elastic layer 104 contacting with the outer vertical surface of the vertical plate 103;
the number of the embedding bulges is the same as that of the embedding grooves, and the embedding bulges are matched with the embedding grooves in shape.
Specifically, in order to increase the bonding firmness between the elastic layer 104 and the outer vertical surface of the vertical plate 103, an embedding groove may be formed in the outer vertical surface of the vertical plate 103, and an embedding protrusion may be formed on the elastic layer 104, so that the embedding groove and the embedding protrusion are matched in shape. The embedded bulges are arranged in the embedded grooves with matched shapes, so that the contact area of the elastic layer 104 and the vertical plate 103 is increased, and the combination firmness of the elastic layer 104 and the outer vertical surface of the vertical plate 103 is improved through mutual occlusion. This way, the outer facade is firmly bonded with the elastic layer 104, so that the elastic layer 104 is not easy to fall off or shift. For example, referring to fig. 1, the inlaid protrusion on the elastic layer 104 may be configured as a first elastic layer 1041, and the rest may be configured as a second elastic layer 1042. The embedding protrusion is made of a material with relatively high rigidity, so that the occlusion firmness and stability of the embedding protrusion and the embedding groove are improved, and the second elastic layer 1042 has better support performance.
In one embodiment, the thickness of the embedded protrusion on the elastic layer 104 is 2-10 mm, and the thickness of the elastic layer 104 at the minimum thickness is 2-15 mm.
Specifically, inlay bellied thickness can be 2 ~ 10mm on the elastic layer 104, the minimum thickness department thickness of elastic layer 104 can be 2 ~ 15mm, and wherein, the thickness of elastic layer 104 is too little, and the great damping effect that just plays of rail brace installation degree of difficulty is limited, and noise reduction is relatively poor.
In one embodiment, as shown in fig. 4-6, the free end of the riser 103 extends at least above the middle of the rail web 202 of the rail 200;
the elastic layer 104 includes a first contact portion contacting an upper portion of the rail limb 203 of the rail 200 and a second contact portion contacting the rail web 202 of the rail 200.
Specifically, the free end of the vertical plate 103 at least needs to extend to a position above the middle of the rail web 202. Because the rail brace is tightly attached to the rail 200, after the rail brace is installed, the height of the vertical plate 103 only needs to be higher than the middle of the rail waist 202, and a good supporting effect can be achieved on the rail 200. At this time, the elastic layer 104 is not in contact with the jaw 201 of the rail 200, and includes only a first contact portion in contact with the upper portion of the rail limb 203 of the rail 200 and a second contact portion in contact with the rail web 202 of the rail 200.
In one embodiment, the free end of riser 103 extends to the jaw 201 of rail 200 as shown with reference to fig. 7 and 8;
the elastic layer 104 comprises a first contact portion in contact with the rail limb 203 of the rail 200, a second contact portion in contact with the rail web 202 of the rail 200 and a third contact portion in contact with the rail jaw 201 of the rail 200.
Specifically, on the basis of the above embodiment, in order to further enhance the supporting capability of the rail brace on the rail 200, the free end of the upright plate 103 may extend to the rail jaw 201 of the rail 200, that is, after the rail brace is installed, the elastic layer 104 includes a first contact portion contacting the rail limb 203 of the rail 200, a second contact portion contacting the rail web 202 of the rail 200, and a third contact portion contacting the rail jaw 201 of the rail 200.
In one embodiment, a first reinforcing structure 106 is disposed at an included angle between the vertical plate 103 and the bottom plate 101, and the first reinforcing structure 106 is a first reinforcing rib or a first reinforcing rib plate;
one end of the first reinforcing rib is connected with the bottom plate 101, the other end of the first reinforcing rib is connected with the vertical plate 103, and the first reinforcing rib, the vertical plate 103 and the bottom plate 101 are connected to form a hollow triangle; the first reinforcing rib plate is triangular, one side of the triangle is connected with the bottom plate 101, and the other side of the triangle is connected with the vertical plate 103.
Specifically, because the contained angle has between riser 103 and the bottom plate 101, receive the application of force back of track 200 after the installation, probably can make the contained angle between riser 103 and the bottom plate 101 change, lead to rail brace deformation, be difficult to laminate closely with track 200 and play good supporting role. Therefore, the first reinforcing structure 106 can be arranged at the included angle between the vertical plate 103 and the bottom plate 101 to improve the above problem, the first reinforcing structure 106 can be a reinforcing rib or a reinforcing rib plate, and the number of the reinforcing ribs or the reinforcing rib plates can be set according to the required strength.
In one embodiment, a second reinforcing structure 107 is arranged between the included angle between the supporting plate 105 and the bottom plate 101, and the second reinforcing structure 107 is a second reinforcing rib or a second reinforcing rib plate;
