Description

Technical Field

[0001] The utility model relates to the technical field of railway accessories, in particular to a rail support. Background Art

[0002] Currently, train speeds are constantly increasing worldwide. However, these high-speed operations place greater lateral forces on rails at turnouts and curves, making it difficult to maintain track gauge and alignment, leading to severe rail deformation and a significant maintenance workload. This puts rail supports in a more prominent role, placing higher demands on their structure and performance.

[0003] Existing rail supports, such as the Chinese utility model patent with publication number CN219752853U and titled "A Rail Support and Curved Rail Support," are installed on sleepers and tightened with spikes and nuts. The rail supports respectively press against the side of the rail and the top of the sleeper. When the rail supports are subjected to force, they are tightened with the spikes and nuts and restricted by the sleepers and tracks to prevent displacement. However, the track will vibrate violently when in use. Relying solely on the fastening of the spikes, sleepers, and tracks, and the matching gaps between the components, the rail supports will swing slightly around the spikes as the axis, making the rail supports unstable and even causing damage to the concrete sleepers due to impacts. Moreover, when installing the rail supports, due to the lack of a matching positioning structure with the sleepers, the sleepers can only be placed and tightened based on experience, which can easily lead to problems such as inaccurate positioning of the rail supports, easy displacement of the installation position, and inadequate installation. Utility Model Content

[0004] The purpose of the utility model is to provide a rail support to solve the problem that the existing rail support lacks a matching positioning structure with the sleeper during installation, resulting in unstable installation and inaccurate positioning of the rail support.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A rail support used to support the outer side of the rail.

[0007] It includes an integrally formed base, end ribs and a reinforcing bottom plate;

[0008] The base is a curved plate that bends in two directions and abuts against the rails and sleepers respectively. A positioning structure is provided between the base and the sleepers, and the base and sleepers are fastened by spikes and nuts.

[0009] The end ribs are located on either side of the base;

[0010] The reinforcing bottom plate is located on the bottom surface of the base, and the reinforcing bottom plate abuts against the sleeper.

[0011] A further technical solution is that a rubber pad is provided on the curved surface of the base that contacts the rail and the sleeper.

[0012] A further technical solution is: the positioning structure includes a strip-shaped protrusion arranged on the outside of the base and a recess arranged on the sleeper and adapted to the strip-shaped protrusion.

[0013] A further technical solution is that strip-shaped holes adapted to the road spikes are provided on the base.

[0014] A further technical solution is that an arc-shaped protrusion and an arc-shaped recess matched with the arc-shaped protrusion are provided between the base and the sleeper.

[0015] A further technical solution is that a positioning pad is provided between the rail support and the sleeper.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] This utility model provides a rail support with a positioning structure provided between the base of the rail support and the rail sleeper. Firstly, this facilitates the installation and positioning of the rail support, allows for faster coordination with the rail sleeper, and works together with the rail sleeper to tighten against the rail. Secondly, it prevents the rail sleeper from swinging slightly due to the spikes, ensuring the stability of the rail support and the safety of the rail sleeper. Thirdly, a reinforcing base plate is provided on the bottom surface of the base to strengthen the structure and enhance wear resistance. This rail support is easy to use and provides stable support and reinforcement for the rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1:

[0031] This embodiment Figure 1 、 Figure 2 and Figure 3 As shown, a rail support is used to support the outer side of the rail 4, which includes an integrally formed base 1, end ribs 2 and a reinforcing base plate 3; the base 1 is a curved plate bent in two directions, and is respectively against the rail 4 and the sleeper 5, a positioning structure is provided between the base 1 and the sleeper 5, and the base 1 and the sleeper 5 are fastened by spikes 6 and nuts 12; the end ribs 2 are located on both sides of the base 1; the reinforcing base plate 3 is located on the bottom surface of the base 1, and the reinforcing base plate 3 is against the sleeper 5.

[0032] The end ribs 2 of the rail support serve to reinforce the curved base 1, which is used to support the sleepers 5 and the sides of the rails 4. The reinforcing base plate 3 cooperates with the sleepers 5 on the bottom surface of the base 1 to strengthen the base 1 and provide wear resistance. During use, the rail support is placed in the mounting groove on the sleeper 5. The positioning structure between the two prevents the rail support from shifting. Finally, the rail support and sleeper 5 are fastened together using spikes 6 and nuts 12. Spring bars can also be installed on the rail support.
