Abstract
Description
Technical Field
[0001] This application relates to the field of railway track technology, specifically to a sleeper. Background Technology
[0002] Railway sleepers, also known as rail sleepers, play a vital role in railway systems. They not only secure the two rails and maintain the distance between them (i.e., track gauge), but also distribute the weight of trains onto the ballast, enhance track stability, and reduce vibration and noise. Traditionally, sleepers were made of wood, but over time, concrete, steel, and even composite materials have gradually been used in their manufacture.
[0003] The standard gauge is 1435 mm (approximately 4 feet 8 inches) and is widely used in most railway systems worldwide. However, many other gauges exist, especially in some regional railway networks. The presence of these different gauges can cause connection problems between railways, increase the number of transfers, and reduce transport efficiency.
[0004] Therefore, a sleeper is proposed, taking into account issues such as train stability and compatibility. Utility Model Content
[0005] This application aims to provide a sleeper that can accommodate trains with different track gauges, reduce the number of transfers, and improve transportation efficiency.
[0006] According to one aspect of this application, a sleeper is provided for fixing a steel rail, comprising:
[0007] The sleeper has multiple mounting slots for fixing the rail;
[0008] The mounting groove is equipped with a fastening system, which is used to fix the rail.
[0009] in,
[0010] The fastening system includes a first spiral spike, a nut, and a flat washer. Each first spiral spike is fitted with a spring clip to connect the sleeper to the rail.
[0011] According to some embodiments, the mounting slot includes a first mounting slot and a second mounting slot:
[0012] The first mounting slot accommodates a steel rail;
[0013] The second mounting slot accommodates one or two steel rails;
[0014] The rails in the first mounting slot and the rails in the other first mounting slot are combined in pairs, or the rails in the first mounting slot and the rails in the second mounting slot are combined in pairs, to accommodate different track gauges.
[0015] According to some embodiments, it also includes:
[0016] The track gauge baffle includes a first track gauge baffle, which is distributed on both sides of the rail to maintain the track gauge between the two rails.
[0017] A baffle seat serves as the mounting base for the first gauge baffle and is used for positioning the gauge baffle.
[0018] According to some embodiments, the first gauge baffle includes a first gauge baffle and a second gauge baffle, wherein the first gauge baffle is installed on the first side of the rail and the second gauge baffle is installed on the second side of the rail.
[0019] According to some embodiments, the gauge baffle further includes a second gauge baffle, which is disposed at the connection between two rail sections.
[0020] According to some embodiments, it also includes pre-embedded gauge baffle blocks and second spiral spikes:
[0021] The pre-embedded gauge baffle block is embedded into the sleeper;
[0022] The second spiral rail spike is used to fix the two rails in the second mounting slot.
[0023] According to some embodiments, the sleeper is in the shape of a hexagonal prism, and a plurality of pre-drilled holes are provided on the sleeper for installing the first helical spike and the second helical spike.
[0024] According to some embodiments, the sleeper includes reinforcing bars, prestressed tendons, and concrete, wherein the concrete includes cement, fine aggregate, coarse aggregate, water-reducing agent, and mixing water.
[0025] According to some embodiments, the sleeper is 3100 mm long;
[0026] The first mounting slot is 214mm long and the second mounting slot is 370mm long.
[0027] According to some embodiments, a total of six rails are placed in multiple mounting slots, with the first rail and the third rail forming the first gauge, the second rail and the fourth rail forming the second gauge, the first rail and the fourth rail forming the third gauge, the second rail and the fifth rail forming the fourth gauge, and the second rail and the sixth rail forming the fifth gauge.
[0028] The first track gauge is 1000mm, the second track gauge is 1067mm, the first track gauge is 1435mm, the first track gauge is 1520mm, and the first track gauge is 1676mm.
[0029] In this example embodiment, the sleeper mounting slots facilitate accurate rail positioning, ensuring consistent track gauge and thus guaranteeing safe train operation. Pre-set mounting slots according to the track gauge accelerate construction and ensure correct installation of each component. The spiral design of the first helical spike in the fastening system increases friction, providing a stronger tightening effect than ordinary fixing spikes. Nuts and flat washers work in conjunction with the first helical spike to ensure a tight connection of all components, preventing rail loosening. The elastic clips have a certain degree of resilience, absorbing vibrations when trains pass, reducing noise and impact, and protecting the sleeper structure. The combined effect of all sleeper components not only ensures the stable installation of the rails but also improves the overall performance and durability of the track system.
[0030] According to the example embodiment, the mounting slot includes a first mounting slot and a second mounting slot. The first mounting slot is used to accommodate one rail, and the second mounting slot can accommodate one or two rails. By combining rails in different mounting slots, support for different track gauges can be achieved. It can be easily adjusted to adapt to various track gauge requirements without replacing the entire sleeper or undertaking large-scale track reconstruction. This flexible track gauge adaptability means that trains can operate in a wider network, reducing transfer times and improving overall transportation efficiency. Attached Figure Description

Therefore, the first component discussed below may be referred to as the second component without departing from the teachings of this application.

[0041] Those skilled in the art will understand that the accompanying drawings are merely schematic diagrams of exemplary embodiments, and the modules or processes in the drawings are not necessarily necessary for implementing this application, and therefore cannot be used to limit the scope of protection of this application.
[0042] The standard gauge is 1435 mm (approximately 4 feet 8 inches) and is widely used in most railway systems worldwide. While the 1435 mm standard gauge is widely used globally, many other gauges still exist in practice, especially in some regional railway networks. The existence of these different gauges is primarily due to historical reasons and different technological development paths.
[0043] To address this issue, continuous technological innovation and improvement are necessary to enhance the overall performance and safety of railway systems. Adopting designs that support multiple track gauges greatly facilitates cross-regional rail transport. Simultaneous compatibility with multiple track gauges simplifies connections between railways of different gauges, reduces transfers, and improves transport efficiency.
[0044] To this end, this application proposes a sleeper that achieves a compatible design, providing great flexibility and adaptability, so that the same track section can be adjusted as needed to accommodate trains with different track gauges.
[0045] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application.
[0046] Figure 1A schematic diagram of the composition of sleepers used for a wall according to an example embodiment is shown.
[0047] See Figure 1 According to an example embodiment, the sleeper includes a sleeper 101, which has multiple mounting slots for fixing rails. Each mounting slot is equipped with a fastening system for securing the rails. The mounting slots include a first mounting slot 103 and a second mounting slot 105. The first mounting slot 103 accommodates one rail, and the second mounting slot 105 accommodates one or two rails. The grooves in the first mounting slot 103 and the second mounting slot 105 of the sleeper are used to install rails and gauge plates.
[0048] Multiple pre-drilled holes 131 are provided on the sleeper. The pre-drilled holes 131 are used to install the fastener system. The pre-drilled holes 131 ensure the accurate installation of the fastener system, eliminating the need for on-site drilling, thus speeding up the construction process and reducing errors.
[0049] According to some embodiments, the sleeper is hexagonal prism-shaped with a narrower top and wider bottom. This structure increases the bottom contact area, helping to distribute pressure more widely across the roadbed, thereby improving the sleeper's load-bearing capacity and stability. The prism has beveled sides, which helps rainwater drain quickly from the sleeper surface, preventing corrosion caused by moisture accumulation.
[0050] See Figure 2 The fastening system includes a first spiral spike 133, a nut, and a flat washer. Each first spiral spike 133 is fitted with a spring clip 135. When the rail 011 is placed on the sleeper 101, the first spiral spike 133 and the spring clip 135 connect the sleeper 101 and the rail 011 together.
[0051] The precise pre-drilling in this example embodiment allows the first spiral rail spike 133 and other fasteners to better secure the rail, enhancing the overall structural robustness.
[0052] According to some embodiments, elastic clips include Type A (Type I) and Type B (Type I) clips. Type A and Type B clips are primarily distinguished by their design shape, size, and function in the track fastening system. Type A clips are designed to have strong elasticity and resilience, mainly used to withstand large lateral forces and ensure the stability of the rail during operation. Type A clips are typically installed on the inner side of the rail, near the center of the sleeper. Due to their design characteristics, they can effectively resist the lateral forces generated when a train passes, ensuring track smoothness. Type B clips may have slightly different elastic characteristics than Type A clips and are typically used to assist in fixing the rail. Type B clips are usually placed on the outer side of the rail, away from the center of the sleeper. Type B clips work together with Type A clips to ensure the stability and safety of the rail.
[0053] See Figure 3A According to some embodiments, the sleeper 101 is further provided with a gauge baffle 151, a baffle seat 155, a pre-embedded gauge baffle block 161, and a second spiral spike 163. The gauge baffle 151 includes a first gauge baffle, which is distributed on both sides of the rail 011 to maintain the gauge between the two rails. The baffle seat 155 serves as the mounting base for the first gauge baffle and is used for positioning the gauge baffle 151.
[0054] The first gauge baffle includes a first-specification gauge baffle and a second-specification gauge baffle. The first-specification gauge baffle is installed on the first side of the rail, and the second-specification gauge baffle is installed on the second side of the rail. The first-specification gauge baffle is a gauge 14 baffle, and the second-specification gauge baffle is a gauge 20 baffle. The gauge 14 baffle is installed on the outer side of the rail, and the gauge 20 baffle is installed on the inner side of the rail. The first gauge baffle is also known as the intermediate gauge baffle. Intermediate gauge baffles are mainly used on straight sections of the track or where the curve radius is large. Their main function is to maintain the gauge between the two rails, thereby ensuring that the train can run smoothly and safely.
[0055] According to some embodiments, the gauge baffle further includes a second gauge baffle, which is used at the joint of two rail sections. The second gauge baffle, also known as the joint gauge baffle, is mainly used at the joint of the track, that is, where two rail sections are connected. Its main task is to maintain the correct gauge at the joint and provide additional support, reducing the impact and wear on the joint caused by the passing of trains, thereby extending the service life of the track and ensuring traffic safety.
[0056] Figure 3A The pre-embedded gauge baffle block 161 and the second spiral spike 163 are embedded into the sleeper. The pre-embedded gauge baffle block 161 is located below the rail and in contact with the concrete sleeper. It is precisely positioned and fixed at the designed distance to accurately maintain the gauge between the two rails when the rails are fixed, thereby ensuring the safety and stability of the train during operation.
[0057] The second spiral rail spike 163 can directly and securely fix two rails to the sleepers without the need for additional components such as spring clips, reducing the number of required parts and making installation simpler and faster. The second spiral rail spike not only effectively reduces the distance between the two rails, allowing for the placement of as many rails as possible within a limited length of the sleepers, but it also better absorbs vibrations generated when trains pass, ensuring a tight connection between the rails and sleepers and improving the overall stability of the track.
[0058] The sleeper proposed in this application, according to an example embodiment, is 3100mm long and has a total of 5 mounting slots, including four first mounting slots with a length of 214mm, and one second mounting slot with a length of 370mm.
[0059] See Figure 3B The system has five mounting slots for a total of six rails. Rails in the first mounting slot are combined in pairs with rails in another first mounting slot, or rails in the first and second mounting slots are combined in pairs to accommodate different track gauges. For example, the first and third rails form the first gauge, the second and fourth rails form the second gauge, the first and fourth rails form the third gauge, the second and fifth rails form the fourth gauge, and the second and sixth rails form the fifth gauge. The first gauge is 1000mm, the second gauge is 1067mm, the first gauge is 1435mm, the first gauge is 1520mm, and the first gauge is 1676mm.
[0060] In this example embodiment, the sleeper has five mounting slots, each with two pre-drilled holes for installing the first and second spiral rail spikes. See the diagram showing the installation effect with six rails. Figure 4 By selecting rails in different mounting slots, different track gauges can be accommodated. Compared to the standard 1435mm gauge, 1000mm, 1067mm, 1520mm, and 1676mm gauges are available, greatly improving the track's versatility and flexibility. This allows the same line to be adjusted as needed to accommodate trains with different gauges, thereby reducing the need for track reconstruction.
[0061] The mounting slots are pre-set in position, and the rails are directly fastened to the designated locations using a fastening system. The pre-set mounting slots ensure that the rails are precisely placed in the required positions, guaranteeing the consistency and accuracy of the track gauge. Using standardized spiral spikes and fasteners greatly simplifies the construction process; workers do not need to make complex adjustments on-site or select different accessories, but simply install the rails according to the pre-set positions.
[0062] Because all components are standardized and the mounting slots are pre-set, the installation process is faster and more efficient, helping to shorten project cycles. Details of the components in the railway track and fastening system:

[0087] The inspection items and equipment in this example embodiment ensure quality control of concrete sleepers during the production process. Every step, from raw materials to the final product, undergoes rigorous testing to guarantee its performance and safety.
[0088] According to some embodiments, the sleepers are manufactured by casting using molds. The specific steps are as follows:
[0089] Raw material preparation, including cutting to length and end-cutting, involves cutting raw materials such as reinforcing bars to the specified length and treating the ends. Reinforcing bar pretreatment involves grouping and placing reinforcing bars into molds according to design requirements. Stirrups and spiral reinforcements are then installed in the molds to enhance the structural strength of the sleepers.
[0090] Tensioning equipment is used to tension steel bars to ensure that the steel bars are in a prestressed state.
[0091] Prepare the mold by applying a release agent to the inner wall of the mold to prevent the concrete from sticking to the mold, and install rubber baffles in the mold to form the shape of the sleepers.
[0092] Concrete mixing involves preparing cement, fine aggregate, coarse aggregate, water-reducing agent, and mixing water, and then mixing these materials to form concrete. Concrete pouring involves pouring the mixed concrete into molds.
[0093] Vibration is used to compact the concrete, remove air bubbles, and ensure that the concrete is evenly distributed; edge cleaning is used to clean excess concrete from the edges of the mold to ensure a smooth surface.
[0094] Curing involves placing the poured concrete sleepers into a curing kiln for curing until they harden.
[0095] Release the tension, which releases the pressure from the tensioning equipment, allowing the steel bars to return to their natural state.
[0096] Demolding: Remove the cured sleepers from the mold. Trimming: Trim the surface of the demolded sleepers, removing burrs and uneven parts. Cutting and stacking: Inspect the trimmed sleepers for quality; those that pass inspection are cut and stacked.
[0097] Finished Product Inspection: A final quality inspection is conducted on the cut and stacked sleepers. Defective products are sent to the scrap warehouse for processing, while qualified products are stored and await shipment. In addition to the final inspection, if any product is found to be defective at any critical step in the process, it will be handled or reworked according to standards.
[0098] By following the above steps, we can ensure the production of high-quality concrete sleepers that meet the requirements of railway track systems and are suitable for the demand for efficient and high-quality infrastructure materials in modern railway construction.
[0099] In this example embodiment, the sleepers manufactured using molds ensure that each sleeper has consistent dimensions and height with minimal error, thus guaranteeing the consistency of track gauge and the overall quality of the track.
