These and / or other aspects become apparent from the following drawings, and those skilled in the art can more easily understand the description of the embodiments of the present application. The drawings are used to depict the embodiments of the present application for illustrative purposes. Those skilled in the art will easily realize from the following description that alternative embodiments of the structures and methods shown in the present application can be used without departing from the principles of the present application.

[0022] As Figure 1 shown, the novel steel rail weld reinforcing device according to the embodiments of the present application comprises first clamping plates 1 and second clamping plates 2 arranged on both sides of the rail waist of the steel rail, the first clamping plates 1 and the second clamping plates 2 are arranged as a convex structure at the steel rail weld position, the first clamping plates 1 and the second clamping plates 2 are connected and fixed by clamps 3, the clamps 3 are arranged as a groove structure, which comprises first clamp end portions 4 and second clamp end portions 5 abutting against the first clamping plates 1 and the second clamping plates 2 respectively, and clamp recesses arranged at the rail bottom.

[0023] The first clamping plate 1 and the second clamping plate 2 are respectively attached to both sides of the rail waist, and the clamping plate at the steel rail weld is provided as a convex structure, which can effectively avoid the weld, and the setting of the convex structure can also ensure the rigidity of the first clamping plate 1 and the second clamping plate 2 at the weld, so that it can better resist the vibration and impact force generated when the train passes, and reduce the deformation and damage of the clamping plate.

[0024] In addition, the detachable clamp 3 is arranged on the steel rail, and the first clamping plate 1 and the second clamping plate 2 are connected and fixed by at least four clamps 3, which can not only enhance the stability and firmness of the connection, prevent loosening or falling off, ensure the safe operation of the rail system, but also effectively reduce the safety hazards caused by loosening or failure of a single clamp 3, ensure the reliability of the clamping plate fixed steel rail, and improve the safety of train operation. The recess structure is adopted, the first clamp end 4 of the clamp 3 abuts on the first clamping plate 1, and the second clamp end 5 of the clamp abuts on the second clamping plate 2, so that the device can bear the load of the train passing to the greatest extent, thereby ensuring the stability of the connection of the clamp 3. The recess part of the clamp 3 is matched with the rail bottom of the steel rail, and the two clamp ends of the clamp 3 are arranged vertically with the recess part of the clamp. The above setting mode can effectively prevent the displacement and deformation of the clamp 3 during use, ensure that the connection is always in a stable state, and the recess part of the clamp 3 can effectively guide and position, so that the first clamping plate 1 and the second clamping plate 2 can accurately cooperate with the first clamp end 4 and the second clamp end 5 to align, and simplify the assembly process of the device.

[0025] In an embodiment, the clamp 3 is provided as at least four, that is, at least two clamps 3 are symmetrically arranged at the positions of the first clamping plate 1 and the second clamping plate 2 which are not provided as convex structures, and the positions of the clamps 3 are equidistantly arranged. It can be understood that more clamps 3 can be arranged to connect with the steel rail, and adaptive design can be made according to the position of the weld.

[0026] In one embodiment, the first clamp end 4 and the second clamp end 5 are provided with a first bolt pair 6 and a second bolt pair 7 which are detachably connected, and the first bolt pair 6 and the second bolt pair 7 are M27 bolt pairs. The first bolt pair 6 and the second bolt pair 7 tightly fix the first clamp plate 1 and the second clamp plate 2 on the railway track by the clamp, which can prevent the clamp 3 from moving or loosening when the train passes, and ensure the stable connection between the first clamp plate 1, the second clamp plate 2 and the track. During use, the M27 bolt pair can bear the vertical load and the lateral load applied on the track by the clamp 3 when the train passes, and transfer these loads to the track and the track base, which effectively ensures the stability and safety of the railway system, and the structure of the M27 bolt pair is simple, and the installation and maintenance are relatively convenient, which can quickly replace the damaged or aged bolts and maintain the good state of the railway track system.

[0027] In one embodiment, the bolt pair includes a hexagonal bolt and a hexagonal nut 8, and the first clamp end 4 and the second clamp end 5 are provided with a limiting assembly for limiting the hexagonal nut 8. The limiting assembly is a limiting plate provided on the first clamp end 4 and the second clamp end 5, which can ensure that the hexagonal nut 8 is in a specific position of the clamp end, and prevent the hexagonal nut 8 from loosening or moving during use, which helps to maintain the fastening state of the bolt pair and improve the stability and safety of the connection.

[0028] In one embodiment, the first clamp end 4 and the second clamp end 5 are provided with threaded openings for the bolt pair to pass through, and the bolt pair threadedly connects the first clamp end 4 and the second clamp end 5 to fix the clamp 3. As shown in Figure 1 and Figure 3 The hexagonal bolt threadedly connects the hexagonal nut 8 and the limiting plate, and then is screwed into the threaded opening of the clamp end to fix the clamp plate on the steel rail.

[0029] In one embodiment, the first clamp plate 1 and the second clamp plate 2 are provided with positioning holes 9, and the ends of the first bolt pair 6 and the second bolt pair 7 abut in the positioning holes to connect and fix the first clamp plate 1 and the second clamp plate 2 on the steel rail. The first clamp end 4 of the clamp 3 abuts against the first clamp plate 1, the hexagonal bolt of the first bolt pair 4 threadedly passes through the hexagonal nut 8 and the limiting assembly, and then is screwed into the threaded opening to be threadedly connected with the first clamp end 4, and the end of the hexagonal bolt is positioned in the positioning hole to abut against the first clamp plate 1 and is fixed on one side of the steel rail. Similarly, after the second bolt pair 7 is threadedly connected with the second clamp end 5, the end of the hexagonal bolt is positioned in the positioning hole to abut against the second clamp plate 2 and is fixed on the other side of the steel rail.

[0030] In one embodiment, as shown in Figure 2 the positioning holes 9 are symmetrically arranged on both sides of the non-protruding structure of the first clamping plate 1 and the second clamping plate 2, and the positioning holes 9 are arranged at least four. It can be understood that, in order to facilitate the adjustment of the position of the clamp, the number of the positioning holes 9 can be arranged to be multiple.

[0031] In one embodiment, the first clamping plate 1 and the second clamping plate 2 are arranged as frosted surfaces on the rail waist contact surface. By frosted processing on the first clamping plate 1 and the second clamping plate 2 on the rail waist contact surface, the friction of the contact surface is increased, so that the device will not be loose, and in the use process, the load of the train is fully conducted to the first clamping plate 1 and the second clamping plate 2, which can ensure that the weld damage is not expanded.

[0032] In the specification provided herein, a large number of specific details are described. However, it can be understood that the embodiments of the present application can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail in order not to obscure the understanding of the present specification.

For example, in the claims, any one of the claimed embodiments can be used in any combination.
