Rail brace for a rail

Abstract

This utility model discloses a rail brace for supporting the outer surface of a steel rail. It includes: a main body composed of an integrally formed base plate and side abutment plates; the upper surface of the base plate has a limiting groove and anti-slip teeth; a diagonal brace plate, the bottom end of which abuts against the anti-slip teeth, and the top end of which abuts against the outer surface of the side abutment plates; a rail spike on the base plate, with a nut on the spike pressing a spring clip; one end of the spring clip is located in the limiting groove, and the other end presses against the diagonal brace plate. This rail brace can stably abut against the outer surface of the rail, effectively preventing rail deformation and gauge increase. Furthermore, the position of the diagonal brace plate is adjustable; based on actual conditions or rail stress analysis, the abutment position between the top end of the diagonal brace plate and the outer surface of the rail can be adjusted to prevent deformation at critical locations. Moreover, the diagonal brace plate eliminates the traditional design of end ribs on both sides of the rail brace, avoiding the problem of unsupported rail brace in the middle, which easily leads to deformation.

Description

Technical Field

[0001] This utility model relates to the field of railway accessories technology, and in particular to a rail brace for steel rails. Background Technology

[0002] Currently, countries are continuously increasing train operating speeds. However, this high-speed operation results in greater lateral forces on the rails in turnout and curve sections, making it difficult to maintain track gauge and alignment. This leads to severe rail deformation, causing the rails to tilt centrifugally or the track gauge to increase, affecting train stability and increasing maintenance workload. In these situations, the role of rail braces becomes even more prominent, placing higher demands on their structure and performance.

[0003] Existing rail braces, such as Chinese utility model patents CN223423047U (titled "A Rail Brace") and CN214992716U (titled "A Universal Rail Brace Pad for Use on Curves"), present challenges. These rail braces are difficult to stably abut or adhere to the outer surface of the rail, or require bolts to lock the rail and rail brace together to ensure a secure fit. Bolts are cumbersome, and their point-fixing method is fixed; if other parts of the rail brace deform, the bolts will not be effective. Furthermore, existing rail braces have ribs on both sides, with no support in the middle, making them prone to deformation. Utility Model Content

[0004] The purpose of this utility model is to provide a rail brace for steel rails to solve the problems that existing railway rail braces cannot stably abut against the outer surface of the steel rails, and that the rail braces are not supported in the middle and are easily deformed.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rail brace for supporting the outer surface of a rail includes: The main body is composed of an integrally formed base plate and side abutment plates, and the upper surface of the base plate is provided with a limit groove and anti-slip teeth; The diagonal brace has its bottom end abutting against the anti-slip teeth, and its top end abutting against the outer side surface of the side abutment plate. The base plate is provided with rail spikes, and the nuts on the rail spikes press the spring strips. One end of the elastic bar is located in the limiting groove, and the other end of the elastic bar presses against the inclined support plate.

[0006] A further technical solution is that the inclined brace plate is provided with a notch adapted to the rail spike.

[0007] A further technical solution is that an arc-shaped plate is provided at the top of the inclined support plate.

[0008] A further technical solution is to provide a limiting structure between the outer arc surface of the arc plate and the side abutment plate.

[0009] A further technical solution is that the limiting structure is a tooth meshing structure.

[0010] A further technical solution is that a rubber pad is provided between the side abutment plate and the rail.

[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes a rail brace for steel rails. This rail brace can stably abut against the outer surface of the rail, effectively preventing rail deformation and gauge increase. Furthermore, the position of the brace plate is adjustable; based on actual conditions or stress analysis of the rail, the abutment position between the top of the brace plate and the outer surface of the rail can be adjusted to prevent deformation at critical locations. Moreover, the brace plate eliminates the traditional design of end ribs on both sides of the rail brace, avoiding the problem of unsupported rail brace in the middle, which easily leads to deformation.

[0022] This implementation example Figure 1 As shown, a rail brace for a steel rail, used to support the outer surface of the steel rail 1, includes: The main body 2 is composed of an integrally formed base plate 3 and side abutment plates 4. The upper surface of the base plate 3 is provided with a limit groove 5 and anti-slip teeth 6. The bottom end of the diagonal brace 7 abuts against the anti-slip teeth 6, and the top end of the diagonal brace 7 abuts against the outer side of the side abutment plate 4. A rail spike 8 is installed on the base plate 3, and the nut 9 on the rail spike 8 presses the spring strip 10. One end of the spring bar 10 is located in the limiting groove 5, and the other end of the spring bar 10 presses against the inclined support plate 7.

[0023] The working process of this utility model is as follows: First, the rail 1 is laid on the track bed. When in use, the main body 2 is placed in the mounting groove on the sleeper. The positioning structure between the two prevents the main body 2 from shifting. The main body 2 can be fixed to the sleeper with bolts and nuts. Then, the inclined support plate 7 and the elastic bar 10 are installed on the main body 2. The elastic bar 10 is pressed onto the inclined support plate 7 with the help of the track spike 8 and the nut 9. The bottom end of the inclined support plate 7 is restricted by the anti-slip teeth 6 and will not slip off. The top end of the inclined support plate 7 presses the outer side of the side abutment plate 4 against the outer side of the rail 1, thereby achieving a stable fit between the rail support and the rail 1.

[0024] Preferably, such as Figure 2 As shown, the diagonal brace 7 is provided with a notch 11 that is compatible with the road stud 8.

[0025] The notch 11 serves two purposes: first, to avoid the rail spike 8, and second, to cooperate with the rail spike 8 to prevent one end of the diagonal brace 7 from being damaged in the direction of the rail 1. Example

[0026] Based on the above embodiments, this embodiment, for example... Figure 3 As shown, an arc-shaped plate 12 is provided at the top of the inclined support plate 7. A limiting structure 13 is provided between the outer arc surface of the arc-shaped plate 12 and the side abutment plate 4. The limiting structure 13 is a toothed meshing structure.

[0027] The outer arc surface of the arc plate 12 and the side abutment plate 4 are provided with teeth that cooperate with each other, which can further prevent the inclined support plate 7 from slipping without hindering the adjustment of the position of the inclined support plate 7.

[0028] Preferably, a rubber pad 14 is provided between the side abutment plate 4 and the rail 1.

[0029] The rubber pad 14 serves as a cushion and prevents slipping.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
