Description

Technical Field

[0001] The utility model belongs to the technical field of rail anti-climbing, and particularly relates to a three-type elastic bar cement sleeper anti-climbing pad. Background Art

[0002] At present, the rails on the dedicated railway lines are fixed to the sleepers by spikes: due to multiple vibrations, the spikes become loose, the lateral gauge of the rails changes, and the rails creep longitudinally, affecting driving safety; on cement sleepers, due to aging of rubber pads, frequent line maintenance and loose spikes, the lateral gauge of the rails changes and the rails loosen and creep longitudinally, affecting driving safety.

[0003] The fasteners used for cement sleeper rails are type I spring clip fasteners, which are fixed with spiral spikes. In actual applications, due to the aging of the rail bottom rubber pad and the loosening of the bolts, other accessories lose their fixing function, the lateral track gauge changes, and the rails 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 three-type elastic bar anti-climbing pad.

[0005] The utility model is implemented in this way: a three-type elastic strip anti-skid pad includes:

[0006] Three types of spring bars, spring bar brackets integrated with pads, development wire rubber pads, anti-climbing pads, shoulder guards integrated with pads, double-layer spring washers, flat washers, nuts, and spiral spikes;

[0007] An elastic bar bracket integrated with the pad is arranged at the bottom of the three-type elastic bar; the anti-climbing pad is fixed to the bottom of the elastic bar bracket integrated with the pad by spiral spikes; the anti-climbing pad is fixed to a wire rubber pad by spiral spikes at the bottom.

[0008] Furthermore, a flat washer is arranged on the top surface of the double-layer spring washer.

[0009] Furthermore, a nut is installed on the top surface of the flat washer.

[0010] Furthermore, the three-type spring clip bracket forms a fixed rail distance with the shoulder, so that the rail is fixed therein.

[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 three-type elastic bar anti-skid pad provided by the utility model can solve the problem that the rails creep longitudinally due to the change of the lateral track of the rails, affecting the driving safety; at the same time, it can solve the problem that on cement sleepers, due to the aging of rubber pads, frequent line maintenance and loosening of spikes, the lateral gauge of the rails changes and the rails loosen and creep longitudinally, affecting the driving safety, thereby greatly improving the stability and safety of the rails.

[0013] Second, the three-type spring bar anti-skid pad design provided by the embodiment of the utility model realizes a more efficient and stable railway track support system for the track stability problems encountered during the use of railway tracks, especially for the track stability requirements of railway dedicated lines, urban transportation or heavy-duty railways. This design provides a comprehensive solution to enhance the stability and service life of the track through a series of innovative component integration.

[0014] First, the present invention effectively increases the elastic support of the track system by providing three types of spring bars and spring bar brackets integrated with the pad, thereby improving the adaptability and shock absorption performance of railway dedicated lines or urban transportation tracks, especially when dealing with track temperature changes or mechanical vibrations. The design of the spring bar bracket integrated with the pad not only simplifies the assembly process, but also improves the stability and durability of the structure.

[0015] The combination of anti-climbing pads and developed silk rubber pads further enhances the shock absorption performance of the bottom of the track, which is particularly important for special railways or urban rail transit, because these application scenarios have higher requirements for the control of rail fixation. The top surface of the anti-climbing pad is connected to the pad with an integrated shoulder to enhance the integrity of the structure and ensure stability in long-term use.

[0016] The design of double-layer spring washers and flat washers further improves the stability of the rails in long-term use of the line. It makes the track installation more accurate and also facilitates future maintenance. The setting of the nuts ensures that the entire system can be tightened and adjusted according to actual conditions, providing a certain degree of flexibility.

[0017] The three-type spring bar anti-climbing pad provided by the utility model solves the problems of insufficient track stability and poor vibration control in the prior art through its innovative structural design and material application, and provides a more reliable, efficient and long-term solution for railway dedicated lines or urban rail transit systems. These technological advances not only help improve the safety and comfort of railway operations, but also have important significance for improving the maintenance efficiency of the track system and reducing maintenance costs.

[0024] 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.

[0025] like Figure 1 , 2 As shown, a new type of spring rail anti-climbing pad provided by the embodiment of the utility model includes:

[0026] Three types of elastic bars: 1. Elastic bar bracket integrated with pad; 2. Development wire rubber pad; 3. Anti-climbing pad; 4. Shoulder guard integrated with pad; 5. Double-layer spring washer; 6. Flat washer; 7. Nut; 8. Spiral spike; 9.

[0027] An elastic bar bracket 2 integrated with the pad is arranged at the bottom of the three-type elastic bar 1; the anti-climbing pad 4 is fixed to the bottom of the elastic bar bracket 2 integrated with the pad via a spiral spike 9; the anti-climbing pad 4 is fixed to the bottom via a spiral spike 9 with a threaded rubber pad 3.

[0028] The top surface of the anti-climbing pad 4 provided in the embodiment of the utility model forms a fixed rail distance with the shoulder through the three-type elastic bar bracket integrated with the pad and the shoulder, so that the rail is fixed therein.

[0029] The top surface of the double-layer spring washer 6 provided in the embodiment of the utility model is provided with a flat washer 7 .

[0030] A nut 8 is installed on the top surface of the flat washer 7 provided in the embodiment of the utility model.

[0031] like Figure 3 , 4 、5 as shown:

[0032] 1. a is the width of the bottom of each type of rail for placing pads.

[0033] When a=116mm, it is a 43kg rail anti-climbing pad;

[0034] When a=134mm, it is a 50kg rail anti-climbing pad;

[0035] When a==152mm, it is a 60kg rail anti-climbing pad;

[0036] 2. k is the gauge adjustment coefficient of the pad applicable to various types of rails.

[0037] 3. The adjustment factor is a multiple of "3" or "5". It is indicated by "·" dots on the pad. Each dot represents 3 or 5 mm.

[0038] 4. The anti-climbing pad of cement sleeper is made of ductile iron, QT450-10.

[0039] The working principle of the three-type spring bar anti-climbing pad provided by the utility model mainly relies on the mutual cooperation and support between its components to ensure the stability and safety of the rails. The following is a detailed explanation of its working principle:

[0040] First, the three-type spring clip 1 is a key fixing component, and a spring clip bracket 2 integrated with the pad is provided at the bottom. This spring clip bracket provides a stable support for the spring clip, so that the spring clip can be firmly fixed in the appropriate position. The main function of the spring clip is to provide lateral constraints on the rails to prevent the rails from moving laterally during the operation of the train.

[0041] Then, the bottom of the spring bar bracket 2 integrated with the pad is fixed with the anti-climbing pad 4 by means of spiral spikes 9. As the main load-bearing and supporting structure, the anti-climbing pad bears the weight from the rails and the train. Through the fixation of the spiral spikes, the anti-slip pad and the rails are more stable, ensuring the stability of the entire structure.

[0042] The bottom of the anti-climbing pad 4 is also fixed with a spiral rail spike 9 to form a development wire rubber pad 3. The development wire rubber pad has good buffering and shock absorption properties, can absorb the vibration and impact force generated during the operation of the train, and protect the anti-climbing pad and the track structure from damage.

[0043] The three-type spring clip bracket and the shoulder form a fixed rail distance, so that the rail is fixed therein.

[0044] A flat washer 7 is arranged on the top surface of the double-layer spring washer 6. The function of the flat washer is to disperse the pressure of the nut 8 to prevent excessive concentrated stress on the double-layer spring washer, thereby extending its service life.

[0045] Finally, a nut 8 is installed on the top surface of the flat washer 7, and the nut is tightly connected to the rail through the spiral spike to ensure that the rail can be firmly fixed on the sleeper. At the same time, the combination of the nut and the spiral spike is also convenient for adjusting and repairing the rail.

[0046] The three-type spring-clip anti-skid pad achieves stable support, lateral restraint and longitudinal anti-climbing for the rails through the coordinated work of its components, thus ensuring the safe and stable operation of the railway line.

[0047] Embodiment 1

[0048] The specific structure of the three-type spring bar anti-skid pad in this embodiment is as follows:

[0049] First, the bottom of the three-type spring bar 1 is provided with a spring bar bracket 2 integrated with the pad to ensure that the spring bar is stably fixed in a fixed position buckled on the bottom of the rail. Then, the bottom of the spring bar bracket 2 integrated with the anti-climbing pad is firmly fixed with a spiral spike 9. At the bottom of the anti-climbing pad 4, the development wire rubber pad 3 is also fixed with a spiral spike 9. This design not only increases the overall stability, but also effectively reduces vibration.

[0050] A flat washer 7 is arranged on the top surface of the double-layer spring washer 6, which further increases the stability of the structure and prevents the nut from loosening during the tightening process.

[0051] Finally, a nut 8 is installed on the top surface of the flat washer 7, and the tightness of the entire structure can be easily adjusted through the nut 8 to ensure that it can work stably in various environments.

[0052] In this embodiment, the size design of the pad fully considers the rail bottom width and gauge adjustment requirements of different types of rails. The width of the pad bottom for placing each type of rail is a, and the gauge adjustment coefficient of the pad applicable to each type of rail is k. The adjustment coefficient k here is a multiple of "3" or "5", which is represented by "·" dots on the pad, and each dot represents 3 or 5 mm. This design allows the pad to easily adapt to the adjustment requirements of different gauges.

[0053] In addition, the anti-climbing pad of the wooden sleeper in this embodiment is made of ductile iron, using QT450-10 material, which has high strength and toughness and can meet the requirements of long-term use.

[0054] Embodiment 2

[0055] The structure of the three-type elastic bar anti-skid pad of this embodiment is similar to that of the first embodiment, but differs in some details.

[0056] Firstly, the connection between the three-type spring bar 1 and the spring bar bracket 2 integrated with the backing plate adopts a more precise locking mechanism to ensure that the spring bar is not easy to loosen when subjected to external force.

[0057] Secondly, the design of the spiral spike 9 has also been improved, and a new type of anti-corrosion material has been adopted, so that the spike can maintain good performance even in harsh environments.

[0058] At the connection between the anti-climbing pad 4 and the double-layer spring washer 6, a vibration-damping gasket is added in this embodiment, which further improves the vibration-damping performance of the entire structure and makes the train more stable during driving.

[0059] In addition, the nut 8 in this embodiment adopts a design that is easier to operate, which is convenient for workers to operate during the tightening and disassembly process.

[0060] In the size design of the pad, this embodiment also takes into account the rail bottom width and gauge adjustment requirements of different types of rails. The rail bottom width of the pad for each type of rail is a, and the gauge adjustment coefficient of the pad for each type of rail is k. The adjustment coefficient k here is also a multiple of "3" or "5", represented by a "·" dot, which is convenient for staff to adjust the gauge.

[0061] Finally, the anti-climbing pad for wooden sleepers in this embodiment is also made of ductile iron QT450-10, which ensures its strength and toughness while improving its corrosion resistance.

[0062] 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.
