The significant technical progress of the utility model is reflected in the improvement of the stability and safety of railway tracks, the simplification of installation and maintenance processes, and the increase of the durability and adaptability of the system. These advances are of great value to the efficient operation and long-term sustainable development of railway transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[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, the embodiment of the utility model provides a type of elastic strip cement pillow anti-climbing pad including:

[0027] Development of a wire rubber pad 1, an iron pad 2, a shoulder 3 integrated with the pad, a spiral spike 4, an elastic clip bracket 5 integrated with the pad, a type of elastic clip 6, a flat washer 7, and a nut 8.

[0028] The top surface of the development wire rubber pad 1 is paved with an iron pad 2; the top surface of the iron pad 2 is provided with a shoulder 3 which is integrated with the pad; the iron pad 2 is fixed with an elastic clip bracket 5 which is integrated with the pad through a spiral spike 4.

[0029] The embodiment of the utility model provides an elastic bar bracket 5 integrated with the backing plate, which is fixed with an elastic bar 6 through a spiral spike 4 .

[0030] The embodiment of the utility model provides a type of elastic bar 6 connected to the nut 8 through a flat washer 7.

[0031] A cross-section of a type 1 elastic rod cement sleeper anti-climbing pad Figure 3 As shown, the overall cross-section of a type of spring-bar cement sleeper anti-climbing pad is as follows Figure 4 shown.

[0032] 1. k is the pad gauge adjustment coefficient.

[0033] 2. When k is determined, a and b are the distances between the shoulder and the spring clip bracket.

[0034] 3. The k adjustment factor is a multiple of "3" or "5". A dot "·" is used on the pad to represent each adjustment unit, and each dot represents an adjustment amount of 3 or 5 mm.

[0035] 4. The anti-climbing pad of wooden sleepers is made of ductile iron, QT45010.

[0036] The working principle of the type of elastic bar cement sleeper anti-climbing pad provided in the embodiment of the utility model is mainly based on the mutual support and fixation between the components to ensure the stability and safety of the rail. First, the development wire rubber pad 1 is used as the bottom foundation of the entire pad, and the top surface is paved with an iron pad 2. The development wire rubber pad has good buffering and shock absorption performance, and can absorb the vibration and impact force generated during the operation of the train, thereby protecting the iron pad and the track structure from damage.

[0037] Next, the iron plate 2 is the main load-bearing and supporting structure, bearing the weight of the rails and the train. Its top surface is provided with a shoulder 3 integrated with the plate, which not only enhances the overall structural strength of the plate, but also plays a role in positioning and guiding the rails, ensuring that the spring bar can be correctly installed and fixed.

[0038] Then, the iron plate 2 is fixed with a spring clip bracket 5 which is integrated with the plate through a spiral spike 4. This spring clip bracket provides a stable support for the spring clip, so that the spring clip can be firmly fixed in an appropriate position. The fixing method of the spiral spike 4 ensures that the connection between the spring clip bracket and the iron plate is firm and reliable and not easy to loosen.

[0039] On the spring clip bracket, a type of spring clip 6 is fixed by a spiral spike 4. As a key fixing component, the shape and structural design of the type of spring clip enable it to fit closely to the rail and provide sufficient lateral restraint to prevent the rail from lateral movement during train operation.

[0040] Finally, a type of spring bar 6 is connected to a nut 8 through a flat washer 7. The function of the flat washer 7 is to disperse the pressure of the nut 8 to prevent excessive concentrated stress on the spring bar, thereby extending its service life. The nut 8 is tightly connected to the rail through the spiral spike to ensure that the rail can be firmly fixed on the pad.

[0041] The spring-bar cement sleeper anti-climbing pad provided by the utility model realizes stable support, lateral restraint and shock absorption of the rails through the coordinated work of various components, thereby ensuring the safe and stable operation of the railway line. It has a reasonable design, a simple structure, is easy to install and maintain, and has a high practical value.

[0049] An iron pad 2 is laid on the rubber pad 1 and fixed on the cement sleeper by means of spiral spikes 4.

[0050] A shoulder 3 integral with the iron pad is installed on the top of the iron pad 2 to ensure that the rail is fixed in the correct position.

[0051] A type of spring bar 6 is installed on the spring bar bracket 5 which is integrated with the backing plate, and is fixed with a flat washer 7 and a nut 8 to ensure the stability and durability of the spring bar.

[0052] 3. Adjustment and inspection:

[0053] Fine-tuning is performed according to the track gauge adjustment factor k to ensure correct installation and safe operation of the track.

[0054] After completing the installation, conduct a comprehensive inspection to ensure that all parts are firmly installed and there is no looseness.

[0055] Maintenance and Replacement:

[0056] 1. Inspection and evaluation:

[0057] Regularly check the wear of the rails and their components, especially the wear of the rubber and iron pads.

[0058] Evaluate the elastic loss of a type of spring clip to ensure it works normally within the standard range.

[0059] 2. Replacement process:

[0060] If damage to the backing plate or spring bar is detected, first remove the nut 8 and flat washer 7.

[0061] Remove the damaged spring clip 6 and check whether the spring clip bracket 5 needs to be replaced together.

[0062] Install new Type 1 spring clips and re-secure using flat washers and nuts.
