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 with symmetrically arranged middle parts of three-type elastic bars. Background Art

[0002] At present, the rails on the dedicated railway lines and urban rail lines are fixed on the sleepers by spikes. Due to the vibration from multiple directions, the spikes loosen, and the transverse gauge of the rails changes, causing the rails to creep longitudinally, affecting driving safety. Through the above analysis, the problems and defects of the existing technology are as follows:

[0003] Due to multiple vibrations, the rail spikes loosen, and the change in the lateral gauge of the rails causes the rails to creep longitudinally, affecting driving safety. Summary of the invention

[0004] In view of the problems existing in the prior art, the utility model provides a wooden sleeper anti-climbing pad with three types of elastic bars symmetrically arranged in the middle.

[0005] The utility model is realized in this way: a wooden sleeper anti-climbing pad is arranged in the middle symmetrical part of a three-type elastic strip, and the specific implementation structure of the middle symmetrical arrangement design is mainly reflected in the following aspects:

[0006] 1. Center placement of wooden sleeper anti-climbing pads: The wooden sleeper anti-climbing pads are placed at the center of the bottom of the rails and fixed by screw spikes. This center placement design allows the pads to evenly bear the weight of the rails and trains, thereby maintaining the stability of the track structure. At the same time, the symmetrical arrangement in the middle makes the force on both sides more uniform, reducing structural deformation or damage caused by uneven force.

[0007] 2. Symmetrical installation of three types of spring bars: Three types of spring bars are installed on both sides of the rail, and the spring bars 3 on each side are placed in the spring bar bracket integrated with the pad to ensure that the spring bars are stably attached to the rail, forming a symmetrical layout. This symmetrical installation of three types of spring bars can provide lateral constraints on the rail and effectively prevent the rail from moving laterally during train operation.

[0008] 3. Threaded spikes are arranged in a triangular pattern: Threaded spikes are designed with solid circular holes in the plan view, and they are distributed in fixed positions on the anti-climbing pads of wooden sleepers. This symmetrical layout not only enhances the stability of the structure, but also makes installation and maintenance work more convenient.

[0009] 4. Material selection and structural integration: The wooden sleeper anti-climbing pad is made of ductile iron QT450-10, which has high strength and wear resistance and can meet the requirements of long-term use. At the same time, the spring bracket and the wooden sleeper anti-climbing pad form an integrated structure, which enhances the integrity and stability of the entire structure.

[0010] The realization structure of the middle symmetrical layout design is mainly realized by the central placement of the wooden sleeper anti-climbing pad, the symmetrical installation of the three-type spring bars, the triangular layout of the threaded spikes, and the integration of material selection and structure. This design not only improves the stability and safety of the track structure, but also optimizes the force distribution and prolongs the service life of the track structure.

[0011] 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:

[0012] First, the utility model provides a wooden sleeper anti-climbing pad symmetrically arranged in the middle of the three-type spring bar, which can solve the problem that the rail spikes are loosened due to multi-directional vibrations, and the transverse track gauge changes of the rails cause the rails to crawl longitudinally, affecting driving safety;

[0013] The utility model provides a three-type spring bar with a wooden sleeper anti-climbing pad symmetrically arranged in the middle, which is specially designed to solve the technical problem that the rails of railway dedicated lines and urban rail lines are prone to displacement or creeping during use. Through the comprehensive use of high-strength materials and innovative structural design, the present invention effectively improves the stability of railway dedicated lines and urban rail lines, reduces the frequency of track maintenance, prolongs the service life of the track, and improves the safety of driving on railway dedicated lines and urban rail lines.

[0014] First of all, the anti-climbing pads for wooden sleepers are made of ductile iron (QT450-10), which has excellent mechanical strength and wear resistance, and can withstand the huge pressure brought by heavy-duty railway dedicated lines and urban rail lines, while extending the service life of the pads. In addition, the good corrosion resistance of ductile iron also ensures the stability of the pads in harsh environments.

[0015] Secondly, the design of the three-type spring clip provides additional support and cushioning for the rails, helping to disperse the impact and vibration on the track, thereby reducing damage to the track structure caused by long-term fatigue. By using the spring clip bracket integrated with the pad to fix the three-type spring clip, it not only ensures a stable connection between the spring clip and the rail and pad, but also facilitates daily maintenance and replacement.

[0016] In addition, the applicability design of the pad in the present invention takes into account the adaptation requirements of rails of different specifications, and by presetting pad options of different widths (such as 43kg, 50kg, and 60kg rails), the versatility and applicability of the anti-climbing pad system are enhanced. The selection of different types of fixing holes (solid line circular holes and dotted line square holes) also provides flexible installation options to adapt to different installation requirements and conditions.

[0017] The utility model provides an anti-climbing pad for wooden sleepers symmetrically arranged in the middle of three types of elastic bars, which has achieved remarkable technical progress in improving the track stability of dedicated railway lines and urban rail lines, reducing maintenance costs, and improving the driving safety of dedicated railway lines and urban rail lines, and has provided strong technical support for the improvement and development of the track system of dedicated railway lines and urban rail lines.

[0018] Second, the design of the anti-climbing pad with wooden sleepers symmetrically arranged in the middle of the three-type elastic strips realized by the utility model shows a series of advantages. Among them, the most prominent feature is the structural design of the symmetrical arrangement in the middle. The advantages of this symmetrical arrangement in the middle will be analyzed in detail below:

[0019] First of all, the symmetrical arrangement in the middle reflects the balance and harmonious beauty of the structural design. Whether from the appearance or function, this design makes the entire structure more stable and balanced. The anti-climbing pads of wooden sleepers fixed by threaded spikes at the bottom of the rails, and the three-type elastic bars fixed by the elastic bar brackets on both sides of the rails and the pads, all follow the principle of symmetry, making the entire structure visually balanced. This balance not only gives people a sense of stability and security, but also improves the stability and reliability of the entire structure.

[0020] Secondly, the design of the symmetrical arrangement in the middle helps to enhance the integrity and coherence of the structure. Since all parts are arranged according to the principle of symmetry, they can echo and support each other to form an organic whole. This integrity not only improves the stability of the structure, but also enhances its use effect. In practical applications, this design enables the entire structure to work together and resist external forces when it is subjected to external loads, thereby ensuring the safety and stability of the structure.

[0021] In addition, the symmetrical arrangement in the middle also helps to improve the practicality and functionality of the structure. Since this design makes the structure more stable and balanced, it can better meet various usage requirements in practical applications. This design can play a positive role in both the smooth operation of the train and the reduction of noise and vibration. At the same time, due to the symmetry and balance of the structure, maintenance and repair work is more convenient and efficient.

[0022] Finally, from the perspective of material selection, the wooden sleeper anti-climbing pad is made of ductile iron QT450-10, which has high strength and toughness and can meet the requirements of long-term use. At the same time, ductile iron has good wear resistance and corrosion resistance, and can maintain good performance under harsh environmental conditions.

[0023] The design of the anti-climbing pad of the wooden sleeper symmetrically arranged in the middle of the three-type elastic strips realized by the utility model has the advantages of balance and stability, overall coherence, practicality and high efficiency, etc. These advantages make it have a wide application prospect and important practical value in the construction of railway dedicated lines and urban rail lines.

[0030] 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.

[0031] like Figure 1 , 2 As shown, an anti-climbing pad with wooden sleepers symmetrically arranged in the middle of three types of elastic bars provided in an embodiment of the utility model comprises:

[0032] Rail 1, wooden sleeper anti-climbing pad 2, three-type spring clip 3, spring clip bracket integrated with pad 4, threaded spike 5;

[0033] A wooden sleeper anti-climbing pad 2 is fixed to the bottom of the rail 1 through a threaded spike 5; three-type spring bars 3 are fixed to both sides of the rail 1 through spring bar brackets 4 that are integrated with the pad.

[0034] The top of the wooden sleeper anti-climbing pad 2 provided in the embodiment of the utility model is provided with an elastic bar bracket 4 which is integrated with the pad.

[0035] The anti-climbing pad 2 for wooden sleepers provided in the embodiment of the utility model is made of ductile iron, QT450-10.

[0036] The cross section of the anti-climbing pad with wooden sleepers symmetrically placed in the middle of the three types of spring bars is as follows Figure 3 As shown, the overall cross-section of the anti-climbing pad with wooden sleepers placed symmetrically in the middle of the three-type spring bars is as follows Figure 4 As shown in the figure, the partial cross-section of the anti-climbing pad of the wooden sleeper is symmetrically arranged in the middle of the three types of spring bars. Figure 5 As shown, a is the width of the bottom of the rail applicable to the pad:

[0037] When a=116mm, it is a 43kg rail anti-climbing pad;

[0038] When a=134mm, it is a 50kg rail anti-climbing pad;

[0039] When a=152mm, it is a 60kg rail anti-climbing pad;

[0040] When using threaded spikes, select solid circular holes in the plan view.

[0041] When ordinary road spikes are used, dashed square holes are selected in the plan view.

[0042] The anti-climbing pad of wooden sleeper is made of ductile iron, QT450-10.

[0043] The working principle of the anti-climbing pad with wooden sleepers symmetrically arranged in the middle of three types of spring bars provided in the utility model embodiment is as follows:

[0044] First, the core component of the utility model is the wooden sleeper anti-climbing pad 2, which is located at the bottom of the rail 1 and fixed by threaded spikes 5. The wooden sleeper anti-climbing pad 2 is made of ductile iron QT450-10, which has high strength and wear resistance and can withstand the weight and impact from the rail and train, thereby ensuring the stability and safety of the track structure.

[0045] Secondly, the three-type spring bars 3 are fixed on both sides of the rail 1 through the spring bar bracket 4 integrated with the pad. The top of the wooden sleeper anti-climbing pad 2 is provided with a spring bar bracket 4 integrated with the pad, which provides a stable support for the spring bar so that it can fit tightly on both sides of the rail. The main function of the three-type spring bar is to provide a fixed rail and lateral constraint on the rail to prevent the rail from lateral movement during the train operation, thereby ensuring the geometric size of the track and driving safety.

[0046] 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 applicable to the pad, the anti-climbing pad configuration of different types of rails such as 43kg, 50kg and 60kg can be achieved. This design makes the utility model highly flexible and widely applicable, and can meet the needs of different railway dedicated lines and urban rail lines.

[0047] In terms of fixing methods, the utility model provides two options: threaded spikes and ordinary spikes. When threaded spikes are used, solid circular holes are selected in the plan view; when ordinary spikes are used, dotted square holes are selected in the plan view. This design allows the appropriate type of spike to be selected as needed in actual applications, thereby ensuring the fixing effect and construction convenience.

[0048] The utility model embodiment realizes the stable fixation of the rail and the lateral restraint and anti-climbing functions through reasonable structural design and component selection. Its working principle is simple and clear, the structure is stable and reliable, and it has high practical value and application prospects.

[0049] Example 1

[0050] In the middle symmetrical layout design, the center line of the rail is first determined, and the wooden sleeper anti-climbing pad is accurately placed on this center line. The wooden sleeper anti-climbing pad is made of ductile iron QT450-10, which ensures the high strength and wear resistance of the pad, thus ensuring that it can stably withstand the pressure from the rail and the train in long-term use.

[0051] Three types of spring bars are symmetrically installed on both sides of the rail. The spring bars 3 on each side are firmly fixed to the anti-climbing pad of the wooden sleeper through the spring bar bracket 4 which is integrated with the pad. The bottom of the spring bar is designed with a spring bar bracket which is integrated with the pad, so that the spring bar can be stably attached to the rail, providing a stable pressure and lateral constraint for the rail to prevent it from lateral movement during the train running.

[0052] In addition, in order to further optimize the stability of the structure, the screw spikes are not symmetrically designed, please refer to the diagram for description. These spikes are symmetrically distributed on the fixing positions of the wooden sleeper anti-climbing pads and the three-type spring bars, which not only enhances the stability of the structure, but also makes installation and maintenance work more convenient.

[0053] Example 2

[0054] In this embodiment, the middle symmetrical layout design also emphasizes the stability of the structure and the uniformity of force. The wooden sleeper anti-climbing pad is still placed at the center of the bottom of the rail and fixed by threaded spikes. This design ensures that the pad can evenly bear the weight from the rail and the train, thereby maintaining the stability of the track structure.

[0055] On both sides of the rail, three types of spring bars are installed in a symmetrical manner. Different from the first embodiment, the spring bars in this embodiment adopt a special anti-slip design to ensure a stable fixing effect even under adverse weather conditions. Similarly, the bottom of the spring bars is also provided with a spring bar bracket integrated with the pad to provide stable support.

[0056] In addition, in order to further improve the stability and durability of the structure, the threaded spikes in this embodiment are made of high-strength materials and are specially treated to increase their corrosion resistance. The symmetrical layout of these spikes not only enhances the overall stability of the structure, but also makes the installation and removal process simpler and more efficient.

[0057] It can be seen from these two embodiments that the middle symmetrical arrangement design improves the stability and safety of the track structure through reasonable structural layout and material selection, while also optimizing the force distribution and extending the service life of the track structure.

[0058] The above description is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any modification, equivalent substitution and improvement made by any technician familiar with the technical field within the technical scope disclosed by the present invention and within the spirit and principle of the present invention shall be covered by the protection scope of the present invention.
