[0003] The structure of existing guardrail pads is usually relatively simple, and most of them are in the form of fasteners that are fixed with a single bolt and are easy to install. However, they often have insufficient fastening force and poor stability. Since strong vibrations are generated when trains pass during use, the pad structure is not vibration-resistant and anti-displacement, which causes the fasteners to easily fall off, causing safety hazards. At the same time, under strong vibrations, the position of the rails cannot be fastened and limited in multiple directions, and the track gauge between the rails cannot be constrained, resulting in unsatisfactory use effects. Utility Model Content

[0007] Preferably, raised support wings are provided on both sides of the base plate, and the support wings cooperate with the sleepers. The surface of the base plate is provided with serrations, and a matching serrated buckle plate is provided above the serrations.

[0015] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0016] Please refer to Figure 1-2 A split buckled rail guard pad comprises two rails 11, the outer side of the rails 11 is provided with a bottom plate 2 for buckling and limiting, and a pad 9 for supporting and limiting is provided between the two rails 11, that is, the outer side of the rail 11 is buckled and fixed by the bottom plate 2, and the other side is buckled and fixed by the pad, wherein the surface of the pad 9 is provided with an arc-shaped elastic strip 10, and the bottom plate 2, the pad 9 and the elastic strip 10 are fixed to the sleeper 1 by penetrating bolts 7.
[0017] In this embodiment, the spring bar 10 is made of spring steel.
[0018] Depend on Figure 1As shown, the bottom plate 2 and the pad 9 (elastic bar) are fixed to the sleeper 1 by bolts 7, which increases the clamping force on the rail and increases the restraining force on the rail. After the two rails are supported by the pad, the deviation of the two rails can be avoided, so that the rail gauge can be better maintained.
[0019] In the utility model, raised support wings 3 are provided on both sides of the base plate 2, and the support wings 3 cooperate with the sleeper 1. The surface of the base plate 2 is provided with serrations, and a matching serrated buckle plate 4 is provided above the serrations. The serrations on the serrated buckle plate 4 are meshed with the serrations on the base plate 2. The serrated buckle plate 4, the base plate 2 and the sleeper 1 are fixedly connected by bolts 7, and are stably fixed on the sleeper 1 as a whole.
[0020] Specifically, the base plate 2 is provided with a locking buckle plate 5 on the side close to the rail 11 , and a gauge block 6 is provided between the base plate 2 and the rail 11 . The gauge block 6 is pressed by the locking buckle plate 5 , and the locking buckle plate 5 is connected to the base plate 2 by a T-bolt 8 .
[0021] A wedge block 61 extending downward is provided below the gauge block 6 , and the wedge block 61 is engaged in the gap between the bottom plate 2 and the rail 11 .
[0022] Since the wedge block 61 is engaged in the gap between the base plate 2 and the rail 11, the vibration and displacement of the rail can be further limited, thereby ensuring the track gauge; in addition, the gauge block 6 and the locking buckle plate 5 are fixed with the base plate 2 by T-bolts 8 to form a whole, and the whole is finally fixedly connected to the sleeper below, which can improve the overall buckling strength and has strong stability.
[0023] In addition, the bottom surface of the pad 9 is provided with limiting protrusions 91 on both sides, and the outer side of the limiting protrusion 91 is provided with a vertical plane, and the limiting protrusion 91 is attached to the outer wall of the rail 11 through the vertical plane; Figure 2 As shown in the figure, when in use, the vertical planes of the two limiting protrusions 91 are in contact with the outer wall of the track, limiting the distance between the two rails and preventing the two from getting close to each other and affecting the track gauge.
[0024] Since the backing plate 9 is fixed on the sleeper 1 by bolts and spring bars 10, and since the spring bars 10 are arc-shaped and have a certain elasticity, they can increase the buckling pressure while having good elasticity, making the structure more stable and strong.
[0025] That is to say, one side of the rail 11 is limited by the pad 9 and the limiting protrusion 91, and the other side is fixed by the locking buckle plate 5 and the gauge block 6, which can ensure the stability of the rail in all directions. When the train passes by and generates severe vibration, the components will not fall off or move, and it has high safety.
[0026] As a preferred solution, a rubber pad 101 is provided below the bottom plate 2 and the rail 11. The rubber pad 101 has a thickness of 5 mm and can play a buffering role during severe vibrations.
[0027] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
