Description

Technical Field

[0001] This utility model relates to the field of railway track technology, and more specifically, to a vulcanized pad. Background Technology

[0002] In railway systems, turnouts are the core components that enable trains to switch from one track to another. However, in high-volume and high-speed environments, the design of traditional railway turnout pads faces numerous challenges. Typically, these pads employ a simple planar structure, directly installed on the turnout sleepers, their primary function being to provide elasticity to absorb the impact and vibration generated when trains pass. However, with increasing train speeds and transport volumes, traditional pads, due to prolonged exposure, are prone to rubber cracking and intrusion by water, sand, and other impurities, leading to pad failure. Furthermore, cleaning and maintenance become complex and cumbersome. Therefore, a new type of railway turnout pad is needed to address these problems. Utility Model Content

[0026] Example 1:

[0027] like Figure 3 As shown, this utility model provides a vulcanizing pad, including a multifunctional vulcanizing pad unit. The multifunctional vulcanizing pad unit includes: an iron base 1, an iron pad 2, and a rubber pad 3. The iron pad 2 is provided with bolt holes, and the upper surface of the iron pad 2 is connected to the iron base 1. Sealing parts 4 are provided at the four edges of the upper surface of the iron pad 2. The bottom surface of the rubber pad 3 is provided with rubber pad bolt holes, which correspond to the bolt holes on the iron pad 2. The rubber pad 3 is disposed at the bottom of the iron pad 2. The pad extends upward and forms a coupling mating structure 5 with the sealing parts 4. The rubber pad 3 and the iron pad 2 are vulcanized into a whole.

[0028] like Figure 1 and Figure 2 As shown in this embodiment, the sealing part 4 is a serrated boss, the mating structure 5 is a serrated groove, and the serrated boss and the serrated groove abut against each other.

[0029] The rubber pad 3 and the iron pad 2 are vulcanized into a single unit.

[0030] It is understood that this invention optimizes the pad structure and improves performance by vulcanizing the rubber pad 3 and the iron pad 2 into a single unit. The integrated vulcanization design not only enhances the durability and reliability of the pad but also effectively improves the stability and ease of maintenance of the track system through the synergistic effect of the multi-functional vulcanized pad unit. Furthermore, the vulcanization process ensures a tight bond between the rubber and metal, reducing vibration and impact, improving the smoothness of train passage, and thus extending the service life of the entire track system.

[0031] The sealing part 4 is a serrated boss, and the mating structure 5 is a serrated groove, with the serrated boss and the serrated groove abutting against each other.

[0032] It is understood that the serrated boss and serrated groove design in this embodiment significantly improves the sealing performance of the vulcanized pad, effectively preventing the intrusion of impurities such as water and sand. This design enhances connection strength, reduces vibration and impact, and ensures track stability. At the same time, the serrated structure facilitates installation and maintenance, adapts to the needs of different railway systems, and improves the durability and reliability of the pad.

[0033] Example 2:

[0034] The difference between this embodiment and Embodiment 1 is that the sealing part 4 and the mating structure 5 are different, specifically as follows: Figure 4 As shown in this embodiment, the sealing part 4 is a dovetail groove, the mating structure 5 is a protrusion, and the dovetail groove and the protrusion abut against each other.

[0035] It is understood that in this embodiment, the sealing performance of the vulcanized gasket is significantly improved through the dovetail groove and protrusion mating structure 5. The dovetail design not only enhances the stability of the gasket but also increases the friction between the gasket and the mating structure 5 through its unique geometry, thereby effectively preventing relative slippage. Furthermore, this design ensures the adaptability and durability of the gasket in different railway systems, significantly improving its ease of maintenance and service life.

[0036] Example 3:

[0037] The difference between this embodiment and Embodiment 1 is that the sealing part 4 and the mating structure 5 are different, specifically as follows: Figure 5 As shown, in this embodiment, the sealing part 4 has a stepped structure, and the mating structure 5 is connected to the edge of the sealing part 4; the vulcanizing pad is also provided with an annular protective shell 6, the outer side of the bottom surface of the protective shell 6 is connected to the mating structure 5, and the inner side of the bottom surface of the protective shell 6 is connected to the sealing part 4.

[0038] Understandably, in this embodiment, the stepped sealing part 4 is connected to the edge of the mating structure 5, and the annular protective shell 6 is provided on the vulcanized pad, significantly improving the sealing performance and structural stability of the vulcanized pad. The stepped design effectively prevents the intrusion of impurities, while the addition of the annular protective shell 6 enhances the impact resistance of the pad, providing additional protection for the internal structure. Furthermore, the tight connection between the protective shell 6 and the mating structure 5 and the sealing part not only reduces the replacement frequency of the rubber pad 3 but also allows for the selection of protective shells 6 made of different materials to adapt to various environmental conditions. Once impurities intrude into the connection, the protective shell 6 is primarily affected, with relatively little impact on the rubber pad 3 and the iron pad 2. Thus, by replacing the protective shell 6, maintenance costs can be significantly reduced and the maintenance process simplified, thereby improving the overall durability and maintenance convenience of the pad.

[0039] Example 4:

[0040] The difference between this embodiment and Embodiment 1 is that the sealing part 4 and the mating structure 5 are different, specifically as follows: Figure 6 As shown, in this embodiment, the mating structure 5 is provided with a through hole, which corresponds to the bolt hole. The vulcanized pad also includes a first internal and external threaded sleeve 7 and a second internal and external threaded sleeve 8, which are mated on both sides of the bolt hole. The outer edge of the through hole is provided with a groove, and the outer edge of the pad bolt hole is provided with a groove. The first internal and external threaded sleeve 7 and the second internal and external threaded sleeve 8 are made of metal. The first internal and external threaded sleeve 7 includes a threaded portion and a head. The head of the first internal and external threaded sleeve 7 is annular and abuts against the groove provided on the outer edge of the through hole. The second internal and external threaded sleeve 8 includes a threaded portion and a head. The head of the second internal and external threaded sleeve 8 is annular and abuts against the groove provided on the outer edge of the pad bolt hole. The inner diameter of the first internal and external threaded sleeve 7 and the second internal and external threaded sleeve 8 corresponds to the bolt.

[0041] Understandably, in this embodiment, the carefully designed grooves on both outer edges of the bolt holes in the rubber pad, which match the heads of the first and second internal and external threaded sleeves 7 and 8, greatly enhance the fixing strength and installation efficiency of the vulcanized pad. The metal material of these threaded sleeves and the fit of the grooves not only improve the connection between the pad and the track components but also significantly reduce wear by effectively distributing the stress. Furthermore, this design simplifies the installation and disassembly process, making maintenance more convenient, thereby comprehensively improving the durability and reliability of the pad.
