Description

Technical Field

[0001] The utility model belongs to the technical field of rail anti-climbing, and particularly relates to an anti-climbing pad for wooden sleepers symmetrically arranged on both sides of three-type elastic bars. Background Art

[0002] At present, the rails on the dedicated railway lines are fixed on the sleepers by spikes. Due to multiple vibrations, the spikes loosen, and the transverse gauge of the rails changes, causing the rails to creep longitudinally, affecting driving safety.

[0003] Through the above analysis, the problems and defects of the prior art are as follows:

[0004] (1) Due to vibrations from multiple directions, the rail spikes loosen and the lateral gauge of the rails changes, affecting driving safety.

[0005] (2) Due to the change in lateral track gauge and the loosening of rails, the rails creep longitudinally, affecting driving safety. Summary of the invention

[0006] In view of the problems existing in the prior art, the utility model provides a wooden sleeper anti-climbing pad with three-type elastic bars symmetrically arranged on both sides.

[0007] The utility model is implemented in that a wooden sleeper anti-climbing pad with three-type elastic strips symmetrically arranged on both sides comprises:

[0008] Anti-climbing pads for wooden sleepers, three types of spring bars, spring bar brackets integrated with pads, and threaded spikes;

[0009] The anti-climbing pads for wooden sleepers are fixed to the wooden sleepers for rails through threaded spikes; the three-type spring bars are placed in spring bar brackets integrated with the pads to fix the rails on the anti-climbing pads.

[0010] Furthermore, it is characterized in that the top surface of the anti-climbing pad of the wooden sleeper is symmetrically provided with an elastic bar bracket integrated with the pad.

[0011] Furthermore, the anti-climbing pad of the wooden sleeper is made of ductile iron, QT450-10.

[0012] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the utility model are as follows:

[0013] First, the utility model provides a three-type elastic bar with wooden sleeper anti-climbing pads symmetrically arranged on both sides, which can solve the problem that the rail spikes are loosened due to multi-directional vibrations, the transverse track gauge of the rails changes, and the rails creep longitudinally, affecting driving safety; at the same time, it can solve the problem that on cement sleepers, due to aging of rubber pads, frequent line maintenance and loosening of spikes, the transverse track gauge of the rails changes and the rails loosen and creep longitudinally, affecting driving safety, and greatly improve the stability and safety of the rails.

[0014] Second, the three-type spring bars provided in the embodiment of the utility model are symmetrically provided with wooden sleeper anti-climbing pads on both sides, which solves the problems existing in the traditional railway track system in preventing rail creeping and improving track stability. Specifically, the utility model effectively enhances the stability of the track, reduces the frequency and cost of track maintenance, and improves the safety and reliability of railway operations by introducing innovative designs.

[0015] First of all, the anti-climbing pad for wooden sleepers in this utility model is made of ductile iron (QT450-10), which provides excellent mechanical strength and durability, and effectively prevents the displacement or creeping of the rails under long-term load. This material selection and design not only ensures the stability and long-term service life of the pad itself, but also reduces the overall maintenance pressure of the track system.

[0016] Secondly, the use of three-type spring bars further enhances the connection strength between the rail and the track base. By symmetrically arranging them on both sides of the rail, the load can be evenly distributed, improving the overall stability of the track. The bottom of the three-type spring bar 3 is provided with a spring bar bracket integrated with the pad. This integrated design simplifies the installation process and improves the reliability of the structure.

[0017] In addition, the use of threaded spikes provides a strong fixing method for the connection between the rail and the anti-climbing pad of the wooden sleeper. The versatility and adaptability of the design are further improved by selecting different hole types (solid line circular holes and dotted line square holes) to accommodate threaded spikes or ordinary spikes.

[0018] The solution provided by the utility model has achieved significant technical progress in improving the stability of the railway track system, extending the service life of the track, reducing maintenance costs, etc. These technical advances are not only conducive to the development of the railway industry, but also provide a reference for technical innovation in related fields.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0026] like Figure 1 , 2 As shown, an anti-climbing pad with wooden sleepers symmetrically arranged on both sides of three-type elastic bars provided in an embodiment of the utility model comprises:

[0027] Wooden sleeper anti-climbing pad 2, three-type spring bar 3, spring bar bracket 4 integrated with pad, threaded spike 5;

[0028] The three-type spring bar 3 is placed in the spring bar bracket integrated with the pad to fix the rail at the designated position of the anti-climbing pad; the threaded spikes 5 fix the anti-climbing pad 2 on the wooden sleeper.

[0029] The three-type spring bars 3 provided in the embodiment of the utility model are placed in a spring bar bracket 4 which is integral with the backing plate.

[0030] The anti-climbing pad 2 for wooden sleepers provided in the embodiment of the utility model is made of ductile iron, QT450-10.

[0031] The cross section of the anti-climbing pad with wooden sleepers symmetrically placed on both sides of the three-type spring bars is as follows Figure 3 As shown, the overall cross-section of the anti-climbing pad with wooden sleepers symmetrically arranged on both sides of the three-type spring bars is as follows Figure 4 As shown, the partial cross-section of the anti-climbing pads of wooden sleepers symmetrically arranged on both sides of the three-type spring bars is shown in Figure 5 As shown, a is the width of the bottom of the rail applicable to the pad:

[0032] When a=116mm, it is a 43kg rail anti-climbing pad;

[0033] When a=134mm, it is a 50kg rail anti-climbing pad;

[0034] When a=152mm, it is a 60kg rail anti-climbing pad;

[0035] When using threaded spikes, select solid circular holes in the plan view.

[0036] When ordinary road spikes are used, dashed square holes are selected in the plan view.

[0037] The anti-climbing pad of wooden sleeper is made of ductile iron, QT450-10.

[0038] The wooden sleeper anti-climbing pad 2 serves as the basis of the entire structure. It is made of ductile iron QT450-10, which has high strength and wear resistance and can withstand the weight and impact from rails and trains.

[0039] The bottom of the rail 1 is fixed to the designated position of the wooden sleeper anti-climbing pad 2 by the three-type spring bar 3. The working principle of the threaded spike is to use the interaction between the threaded hole and the thread resistance to achieve the fastening of the rail and the sleeper. During use, the threaded spike will lock itself in the pre-opened threaded hole through a rotating action, thereby firmly fixing the rail to the wooden sleeper anti-climbing pad.

[0040] On both sides of the rail 1, three types of spring bars 3 are placed in spring bar brackets 4 integrated with the pad. A spring bar bracket 4 integrated with the pad is provided on the top of the pad, which provides a stable support for the spring bar. The main function of the three types of spring bars is to fix the rail and provide lateral constraints for the rail to prevent the rail from lateral movement during train operation.

[0041] The utility model also takes into account the applicability of different rail types. By adjusting the value of the bottom width a of the rail that the pad is suitable for, the anti-climbing pad configuration for different types of rails such as 43kg, 50kg and 60kg can be achieved. This design makes the utility model highly flexible and widely applicable.

[0042] The utility model also mentions the choice of threaded spikes and ordinary spikes. In the plan view, the solid line circular hole indicates the use of threaded spikes, while the dotted line square hole indicates the use of ordinary spikes. This design allows the appropriate type of spike to be selected according to needs in practical applications.

[0043] The embodiment of the utility model realizes the functions of stable support, lateral restraint and longitudinal anti-climbing for the rails through reasonable structural design and component selection, thereby ensuring the safe and stable operation of the railway line.

[0044] The design of the utility model is mainly aimed at improving the stability and safety of the railway track system.

[0045] Combination of rail and wooden sleeper anti-climbing pad:

[0046] The bottom of the rail 1 is firmly fixed on the wooden sleeper anti-climbing pad 2 by three-type spring bars 3. This design uses the wooden sleeper anti-climbing pad 2 made of ductile iron to enhance the stability of the rail and prevent the rail from vibrating and displacing when a train passes.

[0047] The ductile iron anti-climbing pad 2 for wooden sleepers is made of QT450-10 material, which has good strength and toughness, ensuring durability under high load and harsh environment.

[0048] Functions of three types of spring bars:

[0049] The three types of spring bars 3 are placed in spring bar brackets 4 integrated with the pad to fix the rails. These spring bars 3, as an elastic component, mainly maintain the consistency and stability of the rail spacing, reduce the lateral movement of the rails, and thus reduce the maintenance requirements and costs of the track.

[0050] The spring bar 3 is placed in a spring bar bracket 4 which is integrated with the backing plate, thereby enhancing the structural stability and load-bearing capacity of the entire assembly.

[0051] The function of thread spikes:

[0052] The threaded spikes 5 are used to fix the wooden sleeper anti-climbing pad 2 on the sleeper. The design of the threaded spikes ensures a tight connection between the components and avoids the problem of loosening during long-term operation.

[0053] Improved overall system stability and security:

[0054] By integrating the three-type spring bars 3 and the wooden sleeper anti-climbing pad 2 into a compact structure and using strong ductile iron material, this design not only improves the stability of the railway track, but also effectively reduces the maintenance workload and cost of the railway system.

[0055] The improvement of the overall stability and reliability of the system will help ensure the safety of railway transportation and reduce the risk of accidents during train operations.

[0056] The design of the three-type spring-bar rail anti-climbing pads and wooden sleepers of the utility model fully considers the safety and stability requirements of the railway track system under modern high-speed transportation conditions, and optimizes the operating performance and economic benefits of the railway through innovative materials and structural designs.

[0057] The design of this utility model is mainly aimed at improving the stability and safety of the railway track system. The working principle is described in detail below:

[0058] 1. Combination of rails and wooden sleeper anti-climbing pads:

[0059] The bottom of the rail 1 is firmly fixed on the wooden sleeper anti-climbing pad 2 by three-type spring bars 3. This design uses the wooden sleeper anti-climbing pad 2 made of ductile iron to enhance the stability of the rail and prevent the rail from vibrating and displacing when a train passes.

[0060] The ductile iron anti-climbing pad 2 for wooden sleepers is made of QT450-10 material, which has good strength and toughness, ensuring durability under high load and harsh environment.

[0061] 2. Functions of the three types of spring bars:

[0062] The three types of spring bars 3 are installed on both sides of the top surface of the anti-climbing pad 2 and placed in the spring bar bracket 4 integrated with the pad, and firmly fix the rails at the designated position of the anti-climbing pad by their own elastic force. These spring bars 3, as an elastic component, mainly maintain the consistency and stability of the rail spacing, reduce the lateral movement of the rails, and thus reduce the maintenance requirements and costs of the track.

[0063] The bottom of the spring bar 3 is combined with the pad integral spring bar bracket 4, which enhances the structural stability and bearing capacity of the entire assembly.

[0064] 3. The function of thread spikes:

[0065] The screw spikes 5 are used to firmly fix the wooden sleeper anti-climbing pad 2 on the rail wooden sleeper. The design of the screw spikes ensures a tight connection between the components and avoids the loosening problem during long-term operation.

[0066] 4. Improved overall system stability and security:

[0067] By integrating the three-type spring bars 3 with the wooden sleeper anti-climbing pads 2 in a tight structure and using strong ductile iron material, this design not only improves the stability of the railway track, but also effectively reduces the maintenance workload and cost of the railway system.

[0068] The improvement of the overall stability and reliability of the system will help ensure the safety of railway transportation and reduce the risk of accidents during train operations.
