Description

Technical Field

[0001] This utility model relates to the field of railway sleeper technology, and in particular to a novel railway sleeper. Background Technology

[0002] The sleeper is a type of railway track maintenance equipment. The sleeper not only supports the rails and maintains their position, but also transmits the enormous pressure from the rails to the track bed.

[0003] Currently, Type III railway sleepers increase track height and reduce the safety space above the carriage. At the same time, their narrow design reduces the stress area and leads to uneven load distribution, making the track prone to deformation during long-term use. Furthermore, the track is prone to lateral displacement on curves and complex terrain, reducing the durability of the railway. Therefore, we propose a new type of sleeper to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing railway track type III sleeper, which increases the track height, reduces the safety space on the top of the carriage, and has a narrow design that reduces the stress area, leads to uneven load distribution, and makes the track prone to deformation during long-term use. In addition, the track is prone to lateral displacement on curves and complex terrain, which reduces the durability of the rail. Therefore, a new type of sleeper is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel railway sleeper includes a sleeper body, with rail-supporting grooves formed on all four ends of the sleeper body. A first connecting block is fixedly connected to the upper side of one side of the sleeper body, and a second connecting block is fixedly connected to the lower side of one side of the sleeper body.

[0006] Preferably, the cross-section of the sleeper body is X-shaped.

[0007] Preferably, the bottom of the rail groove has two mounting holes.

[0008] Preferably, the cross-sections of both the first connecting block and the second connecting block are L-shaped, and the first connecting block and the second connecting block are engaged with each other.

[0009] Preferably, both the first connecting block and the second connecting block have through holes inside, and mounting bolts are installed between the first connecting block and the second connecting block.

[0010] Preferably, elastic rubber pads are glued to the bottom of all four ends of the sleeper body, and the surface width of the elastic rubber pads is the same as the width of the bottom of the ends of the sleeper body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This device allows for easy splicing of multiple sleeper bodies by installing bolts through the first and second connecting blocks. This enables the track to be laid on the surface of the rail bearing groove for installation, facilitating its widespread use in subway or conventional railway tunnels in a ballastless manner. It reduces track elevation, increases the safety space above the carriage, and its wide-spread design increases the stress area, evenly distributes the load, and reduces track deformation. When used on curves and complex terrain, it can effectively prevent lateral displacement, enhance the durability of the rail, and the elastic rubber pad glued under the sleeper body can also play a role in vibration reduction.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 A new type of railway sleeper, based on the existing low-profile Type III sleeper structure, includes a sleeper body 1. Each of the four ends of the sleeper body 1 has a rail-bearing groove 2. The cross-section of the sleeper body 1 is X-shaped. This X-shaped cross-section, through its wide-radius design, increases the load-bearing area, evenly distributes the load, and reduces track deformation. When used on curves and complex terrain, it can effectively prevent lateral displacement and enhance the durability of the rails. When used in suitable locations, the angle of the "X" can be adjusted to accommodate the spacing between the two inner rail groove plates on curves. This can be changed during prefabrication. Two mounting holes are provided at the bottom of the rail-bearing groove 2, facilitating rail installation. These holes also allow for easy fixing of the rails to the grooves using anchor bolts, facilitating the assembly and disassembly of the rail seat. A first connecting block 3 is fixedly connected to the upper side of one side of the sleeper body 1, and a second connecting block 5 is fixedly connected to the lower side of one side of the sleeper body 1.

[0016] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the cross-sections of the first connecting block 3 and the second connecting block 5 are both set to L-shape. The first connecting block 3 and the second connecting block 5 are used to engage with each other. By setting the cross-sections of the first connecting block 3 and the second connecting block 5 to L-shape, it is convenient for the first connecting block 3 and the second connecting block 5 to engage and connect.

[0017] Furthermore, refer to Figure 1 and Figure 2 It can be seen that both the first connecting block 3 and the second connecting block 5 have through holes inside. An installation bolt 4 is installed between the first connecting block 3 and the second connecting block 5. By passing through the through holes inside the first connecting block 3 and the second connecting block 5 with the installation bolt 4, the first connecting block 3 and the second connecting block 5 can be conveniently connected and limited, and multiple sleeper bodies 1 can be assembled and used.

[0018] Furthermore, refer to Figure 3 It can be seen that elastic rubber pads 6 are glued to the bottom of all four ends of the sleeper body 1. The surface width of the elastic rubber pads 6 is the same as the width of the bottom of the end of the sleeper body 1. Through the elastic rubber pads 6 glued to the bottom of all four ends of the sleeper body 1, the sleeper body 1 can be subjected to vibration damping and buffering, and noise can be reduced.

[0019] Working principle: When this utility model is in use, when the sleeper body 1 is in use, according to the attached... Figure 1 Appendix Figure 2 and attached Figure 3 By laying multiple sleeper bodies 1 flat on the track bed, one set of sleeper bodies 1 can drive the first connecting block 3 to engage with the second connecting block 5 fixed on the side of another set of sleeper bodies 1, and the mounting bolt 4 can pass through the first connecting block 3 and the second connecting block 5, which can easily fix and connect multiple sleeper bodies 1, thereby fixing the rail to the rail bearing groove 2 by anchoring rail spikes, and making it easy to lay the rail on top of multiple sets of sleeper bodies 1; The above is the complete working principle of this utility model.

[0020] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
