[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0022] Example

[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, is a device for preventing rail overturning provided by an embodiment of the present utility model, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the device may include a main body including a vertical end and a horizontal end;

[0024] A connecting assembly is used to connect the main body with the pad, so that the vertical end is tightly connected to the waist of the rail, and the lower surface of the horizontal end is connected to the upper surface of the pad; the main body is used to support the rail to prevent the rail from being displaced or overturned when subjected to lateral force.

[0025] Furthermore, the connecting assembly includes a pitch wedge, a K-shaped iron, a spring bar, and a bolt; the K-shaped iron is welded to the base plate, and the bolt is connected to the K-shaped iron. The bolt passes through a mounting hole in the main body and secures the spring bar with a nut, so that the two spring arms of the spring bar are pressed against the pitch wedge. The main body and the base plate are clamped and fixed together by the pitch wedge and the K-shaped iron. Bolt holes are provided on the horizontal end of the main body, and bolts are used to secure the support body. The bolt passes through the K-shaped iron on the base plate to secure the spring bar and cooperate with the pitch wedge to secure the support device body.

[0026] This device supports rails, preventing them from shifting or tipping over when subjected to lateral forces. The support body has a vertical end that rests against the rail's waist and a horizontal end connected to a pad. The support body is secured to the pad using pre-set bolt holes and K-shaped irons, which engage with the bolts and spacer wedges on the pad.

[0027] The relative position between the main body and the rail can be adjusted by turning the distance adjusting wedge.

[0028] The main body is made of cast steel to improve support strength and durability.

[0029] When in use, the vertical end of the main body of the device rests against the rail waist, while the horizontal end is in contact with the backing plate. The main body is clamped in place by a spacer wedge and a K-shaped iron. The K-shaped iron is welded to the backing plate, and the spring bar is bolted to the K-shaped iron. The two spring arms of the spring bar press against the spacer wedge.

[0030] To ensure that the support device can fit tightly and stably to the waist of the rail, the flipping of the distance adjusting wedge can fine-tune the position of the support device, which can be better applied to small radius curved tracks and track bending deformation caused by the thermal expansion and contraction characteristics of the rail material, reducing the lateral displacement and eversion risk of the rail.

[0031] In summary, the rail overturn prevention device provided in this application can be used to prevent rail overturning under extreme conditions, enhance rail stability, and prevent it from tipping over or tilting when subjected to external forces. This device achieves its function by increasing the lateral rigidity of the rail, providing additional support, or limiting rail displacement. Furthermore, the device has a simple structure and effectively improves the stability and safety of the rail when subjected to lateral forces, ensuring smooth and safe railway operations.
