Description

Technical Field

[0001] This utility model relates to the field of railway track technology, and more specifically to an iron pad for railway fasteners. Background Technology

[0002] In railway tracks, track pads are crucial components of fasteners, used to secure rails and sleepers. Currently, track pads are fixed with bolts, but gaps exist at the connection between the bolts and the pads. Rainwater seeps into these gaps during rainy weather, causing bolt corrosion and increasing maintenance difficulty.

[0003] The prior art discloses an iron pad for railway fasteners, which rotates the protective plate by a pivot and then fixes it to the main body of the pad by a magnet. This seals the connection between the bolt and the threaded hole, preventing rainwater from entering the gap between the bolt and the main body of the pad and causing corrosion. However, the protective plate is fixed by a magnet, and the magnetism may weaken after long-term use, allowing rainwater to still seep into the gaps and corrode the bolt. Therefore, this utility model proposes an iron pad for railway fasteners. Summary of the Invention

[0004] The purpose of this utility model is to provide an iron pad for railway fasteners, which, through a double fixing structure and drainage design, prevents rainwater from seeping into the bolt connection, effectively prevents corrosion, and extends service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A railway fastener pad includes a pad body with an inner groove at the upper end and a support plate inside the inner groove. Both sides of the upper end of the support plate have protrusions. A buffer portion is provided between the support plate and the inner groove. Side grooves are provided on both sides of the pad body. A protective cover is rotatably connected to the upper end of each side groove via a pivot. The protective cover has several drainage holes. The side grooves are fixed to a lower pad and the ground via bolts. The protective cover is fixed to the pad body via magnetic blocks and a fixing structure, including fixing nails.

[0006] Furthermore, a slider is fixedly provided on both sides of the support plate, and a groove is provided at both ends of the inner groove, and the slider is inserted into the groove.

[0007] Furthermore, the buffer section is provided with honeycomb holes, and buffer springs are embedded in each of the honeycomb holes.

[0008] Furthermore, the buffer portion is made of an energy-absorbing material, including polyurethane foam.

[0009] Furthermore, the fixing nail penetrates the through hole of the protective cover and is inserted into the fixing hole of the pad body. The lower end of the fixing hole is provided with a slot, and the lower end of the fixing nail is provided with an inner groove. A locking block is provided in the inner groove, and the locking block is connected to the inner groove by a high-elastic spring. The locking block is inserted into the corresponding slot.

[0010] Furthermore, two sliders are fixedly provided on both sides of the card block, two sliding grooves are provided on both sides of the inner groove, the two sliders are inserted into the two sliding grooves, and an inclined surface is provided at the lower end of the card block, and the card groove matches the card block.

[0011] Furthermore, the lower end face of the side groove is provided with an inclined surface two, which is higher on the inside and lower on the outside, and the lower end of the inclined surface two corresponds to the drain hole.

[0012] Furthermore, the upper end of the side groove is provided with a protrusion, and a threaded hole is provided between the protrusion and the main body of the pad. The bolt structure includes an external thread post and an internal thread post. The external thread post is provided in the threaded hole through a threaded connection. A bolt head is provided at the upper end of the external thread post. A sealing gasket is embedded between the bolt head and the upper end of the protrusion.

[0013] Furthermore, the external threaded column is provided with a second threaded hole, and the internal threaded column is connected to the second threaded hole by a thread. The upper end of the internal threaded column is provided with a second bolt head, and the lower end of the internal threaded column is provided with a triangular block.

[0014] The beneficial effects of this utility model are as follows: The protective cover of this utility model achieves initial and rapid fixation through magnetic blocks, and then forms a rigid lock through fixing nails, clips and slots, thereby achieving a double fixing structure. This can effectively prevent magnetic failure and loosening of the protective cover, thus preventing rainwater from entering the bolt connection.

[0018] like Figure 1 As shown in the specific embodiment, a railway fastener iron pad includes a pad body 1. The upper end of the pad body 1 is provided with an embedded groove 101. A support plate 3 is provided in the embedded groove 101. Both sides of the upper end of the support plate 3 are provided with protrusions 10. The rail can be fixed between the protrusions 10 to achieve limiting and fixing.

[0019] like Figure 1 and Figure 4 As shown, a buffer section 2 is provided between the support plate 3 and the embedded groove 101. The buffer section 2 effectively absorbs the vibration of the train passing through, prevents the bolt connection from loosening due to long-term vibration, and extends the bolt life. The buffer section 2 is provided with honeycomb holes 201, and buffer springs 11 are embedded in each honeycomb hole 201. The buffer section 2 is made of energy-absorbing material, including polyurethane foam. The combination of energy-absorbing material and honeycomb holes 201 can greatly improve the vibration absorption efficiency and protect the stability of the bolt structure.

[0020] like Figure 1 and Figure 2 As shown, the main body 1 of the pad has side grooves 4 on both sides. The upper end of the side grooves 4 is rotatably connected to the protective cover 7 via a rotating shaft. The protective cover 7 has several drainage holes 701. The lower end face of the side grooves 4 has an inclined surface 14. The inclined surface 14 is higher on the inside and lower on the outside. The lower end of the inclined surface 14 corresponds to the drainage hole 701. The design of the inclined surface 14, which is higher on the inside and lower on the outside, guides rainwater to flow quickly to the drainage hole 701, avoids rainwater accumulation at the bolt connection, and eliminates the source of corrosion. The side groove 4 is fixed to the underside pad and the ground by bolts. The protective cover 7 is fixed to the pad body 1 by magnetic blocks 15 and fixing structure. The magnetic blocks 15 achieve quick initial fixation of the protective cover 7, and the fixing structure forms a rigid lock, which completely solves the problem of rainwater seepage after the magnetic force weakens.

[0021] like Figure 1 and Figure 3As shown, the fixing structure includes a fixing nail 8. The fixing nail 8 passes through the through hole 702 of the protective cover 7 and is inserted into the fixing hole 13 of the pad body 1. The fixing hole 13 has a slot 18 at its lower end and an inner groove 801 at its lower end. A locking block 9 is provided in the inner groove 801. The locking block 9 is connected to the inner groove 801 by a high-elasticity spring 12. The locking block 9 is inserted into the corresponding slot 18. The elastic force of the high-elasticity spring 12 can push the locking block 9 into the corresponding slot 18 to achieve effective fixing.

[0022] The two sides of the locking block 9 are fixed with sliders 901, and the two sides of the inner groove 801 are provided with sliding grooves 802. The sliders 901 are inserted into the sliding grooves 802. The lower end of the locking block 9 is provided with an inclined surface 902. The locking groove 18 matches the locking block 9. When it is necessary to remove the fixing nail 8, only a certain pulling force needs to be applied to the fixing nail 8. The inclined surface 902 will gradually squeeze the locking block 9 into the inner groove 801, and the fixing nail 8 can be removed, so that the protective cover 7 can be opened.

[0023] The support plate 3 is fixedly provided with sliders 301 on both sides, and the inner groove 101 is provided with grooves 102 at both ends. The sliders 301 are inserted into the grooves 102. The sliders 301 and the grooves 102 are provided to prevent the support plate 3 from falling out of the inner groove 101.

[0024] The upper end of the side groove 4 is provided with a protrusion 16. A threaded hole 401 is provided between the protrusion 16 and the main body 1 of the pad. The bolt structure includes an external threaded post 6 and an internal threaded post 5. The external threaded post 6 is provided in the threaded hole 401 through a threaded connection. The upper end of the external threaded post 6 is provided with a bolt head 601. A sealing gasket 17 is embedded between the bolt head 601 and the upper end of the protrusion 16. The protrusion 16 makes the gap at the bolt connection located at the high point of the side groove 4, reducing the possibility of it coming into contact with rainwater. The external threaded post 6 presses the protrusion 16 with the sealing gasket 17 to form the first sealing barrier, effectively preventing rainwater from seeping in from the threaded connection gap.

[0025] The external threaded column 6 has a threaded hole 602 inside, and the internal threaded column 5 is connected to the threaded hole 602 by a thread. The upper end of the internal threaded column 5 is provided with a bolt head 501, and the lower end of the internal threaded column 5 is provided with a triangular block 502. The nested thread design of the internal threaded column 5 and the external threaded column 6, together with the reverse fixation of the triangular block 502, enhances the overall connection strength and prevents loosening caused by long-term vibration.

[0026] Working principle: The protective cover 7 is double-fixed, mainly by magnetic block 15 adsorbing the pad body 1 to form the first sealing barrier, thereby isolating external rainwater. When the fixing nail 8 is inserted into the fixing hole 13, the inclined surface 902 of the locking block 9 is compressed by the locking groove 18 to the compressed state of the high-elasticity spring 12. When the locking block 9 moves to the corresponding locking groove 18, the high-elasticity spring 12 pushes the locking block 9 to pop out and lock into the locking groove 18, forming a rigid self-locking, completely preventing rainwater from seeping into the bolt connection gap, solving the corrosion problem caused by magnetic failure, and setting up a subsequent protective structure. When rainwater accidentally seeps into the side groove 4, it can automatically flow along the inclined surface 14. The water flows to the drain hole 701, which quickly drains the accumulated water, preventing rainwater from accumulating and corroding the bolts. The polyurethane foam in the buffer part 2 absorbs high-frequency impacts, and the buffer spring 11 inside the honeycomb hole 201 is compressed and deformed to disperse low-frequency vibration energy, which can protect the bolt connection structure and prevent loosening due to long-term vibration. The external threaded post 6 is screwed into the threaded hole 401 until the sealing gasket 17 is pressed by the bolt head 601, and the internal threaded post 5 is screwed into the threaded hole 602 until the bolt head 501 presses against the bolt head 601. The triangular block 502 is embedded and fixed, which can enhance the overall connection strength and prevent loosening due to long-term vibration.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
