Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a rail corrugation suppression device and its installation method. Background Technology

[0002] In the field of rail transit, the wheel-rail system, as the main form of high-speed rail and urban rail in my country, is facing the increasingly prominent problem of rail corrugation under the long-term operation of vehicles. Rail corrugation refers to the wavy wear phenomenon that occurs on the working surface of newly laid or ground rails after a period of use. Rail corrugation brings many negative impacts. It exacerbates rail vibration, leading to increased excitation frequency, increased amplitude, and more complex vibration transmission paths, thereby intensifying the vibration of the track and wheels, affecting the track foundation structure and passenger comfort. At the same time, the high-frequency excitation caused by corrugation significantly increases wheel-rail noise. The easy development of rail corrugation leads to strong wheel-rail interaction, causing damage to some components of the track and train, such as broken rail fasteners and damage to vehicle parts. This not only accelerates the wear of track and train components and shortens their service life, but also poses a threat to train operation safety.

[0003] While common rail grinding is currently the primary method for controlling corrugation, it requires rail grinding equipment costing tens of millions of yuan. Furthermore, the rail head profile changes significantly after grinding, affecting wheel-rail contact geometry and dynamic performance. This method is neither economical nor a fundamental solution to corrugation. Applying friction modifiers to the rail surface requires advanced technology, and the application quality is difficult to guarantee. It can also negatively impact train traction performance, similarly failing to completely resolve rail corrugation. Installing corrugation suppressors on the rails is an effective means of suppressing rail corrugation. Existing corrugation suppressors typically involve placing elastic elements or rubber blocks on the rail to absorb and disperse the energy of rail vibrations, thereby reducing vibration and noise and mitigating corrugation. However, the frequencies of existing suppressors are generally fixed, making it difficult to meet the suppression requirements of rails with different corrugation frequencies.

[0004] Existing patent CN202411275098.1 discloses an adjustable frequency rail vibration absorption device and its application method for suppressing rail corrugation. The device includes a mass block, connecting rods, a damping rubber ring, and rail connection fixing clips. The rail connection fixing clips are compatible with the rail structure. The connecting rods are mounted on the rail connection fixing clips, with the damping rubber ring positioned between them. The mass block is detachably fitted onto both ends of the connecting rod, and its position on the connecting rod is adjustable. This fulfills the design objective of suppressing rail corrugation, namely, suppressing the lateral dynamic creep rate between the wheel and rail, increasing the track attenuation rate within a specific frequency range, mitigating the damage caused by corrugation, alleviating environmental vibration and noise problems, reducing the frequency of rail replacement, extending the service life of the rail, and significantly reducing maintenance costs. However, the aforementioned patent only uses mass blocks on both sides of the rail web, resulting in a relatively poor effect on suppressing rail corrugation and a limited reduction in vibration and noise.

[0017] The installation method of the above-mentioned rail corrugation suppression device includes the following steps:

[0018] S1. Fix the first counterweight ball to the first flexible rope, fix the second counterweight ball to the second flexible rope, fix the third counterweight ball to the bottom end of the third flexible rope, fix the two ends of the first and second flexible ropes to the inner wall of the box respectively, and fix the top end of the third flexible rope to the top plate.

[0021] S4. As the energy dissipation box moves, it drives the clamping plate to slide inward via the transmission rod. The clamping plate clamps the box body and connecting block to the web of the rail, completing the installation of the suppression device.

[0022] The advantages and positive effects of the rail corrugation suppression device and installation method described in this invention are:

[0023] 1. The present invention provides a vertical first flexible rope and a second flexible rope inside the box, and a first counterweight ball and a second counterweight ball are respectively provided on the first flexible rope and the second flexible rope. The box is filled with an inhibitor. Through the viscous resistance and vibration of the inhibitor, the dissipation of vibration energy is accelerated. Furthermore, the vibration of the first counterweight ball and the oscillation of the second counterweight ball in the inhibitor also accelerates the dissipation of vibration energy, suppresses the vibration of the rail, and reduces the corrugation phenomenon of the rail.

[0024] 2. The present invention uses a fixing mechanism to fix the box body to both sides of the rail web. The energy consumption box drives the clamping plate to move through the transmission rod. So that when the energy consumption box contacts the bottom of the rail, the clamping plate clamps the box body on the rail. The suppression device is easy to install.

[0025] 3. The base of this invention is provided with a locking structure to lock the energy consumption box. By locking the energy consumption box with the locking structure, the stability of the contact between the energy consumption box and the box body and the rail is improved, the dissipation effect of vibration energy is improved, and the corrugation phenomenon of the rail is reduced.

[0026] 4. The energy dissipation box of this invention has several third flexible ropes evenly arranged on its top plate. A third counterweight ball is fixedly installed at the bottom of each third flexible rope. Due to inertia, the third counterweight ball's oscillation lags behind the vibration direction of the energy dissipation box, causing some instantaneous oscillation directions of the third counterweight ball to be opposite to the instantaneous vibration direction of the energy dissipation box. The third counterweight ball hinders the vibration of the energy dissipation box, increases energy consumption, and is beneficial for improving the dissipation of rail vibration energy, reducing noise and rail vibration, and suppressing rail corrugation. Furthermore, the third counterweight ball has a high degree of freedom, providing good suppression of both lateral and vertical rail vibrations.

[0051] In this application, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0052] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0053] like Figure 1 , Figure 2 , Figure 3 As shown, a rail corrugation suppression device includes a suppression mechanism 1, which is symmetrically arranged on both sides of the web of a rail 3. A fixing mechanism 2 is provided at the bottom of the rail 3 to fix the suppression mechanism 1 to the rail 3. The suppression mechanism 1 suppresses the vibration and noise of the rail 3 from both sides.

[0054] like Figure 4 , Figure 5 As shown. The suppression mechanism 1 includes several boxes 11 arranged in a linear array. Several first suppression layers and second suppression layers are disposed inside each box 11, with the first and second suppression layers spaced apart. Each first suppression layer includes several first flexible ropes 15 arranged in a linear array, with both ends of each rope fixed to the inner walls of both sides of the box 11. Several first counterweight balls 16 are fixedly mounted on each of the first flexible ropes 15. The second suppression layer includes several second flexible ropes 17 arranged in a linear array, with both ends of each second flexible rope 17 fixed to the inner walls of both ends of the box 11. The second flexible ropes 17 are arranged perpendicular to the first flexible ropes 15. Several second counterweight balls 18 are fixedly mounted on each of the second flexible ropes 17, and the second counterweight balls 18 are offset from the first counterweight balls 16. The first counterweight balls 16 and the second counterweight balls 18 can be metal balls.

[0055] The top of the housing 11 has an inlet 13, and the bottom has an outlet 14. Both the inlet 13 and outlet 14 are sealed with rubber plugs. The interior of the housing 11 is filled with inhibitor, with the inhibitor filling 60%-80% of the housing's internal cavity. Adding too much inhibitor will affect the weight of the suppression mechanism 1 and the vibration of the inhibitor, which is detrimental to reducing the vibration and noise of the rail 3. Adding too little inhibitor results in poor suppression of the rail 3's vibration and noise. When 60%-80% of the inhibitor is added to the housing 11, a relatively good vibration and noise suppression effect is achieved. The first counterweight ball 16 and the second counterweight ball 18 are immersed in the inhibitor.

[0056] The inhibitor is silicone oil, which has good viscosity and stability. During the vibration of the rail 3, the silicone oil vibrates and flows within the housing 11, generating viscous resistance that hinders the transmission of vibration. This resistance consumes vibration energy. Furthermore, the friction between silicone oil molecules during vibration converts vibration energy into heat energy, effectively reducing the vibration intensity of the rail 3, effectively attenuating the vibration of the wheel-rail system, and mitigating the corrugation phenomenon of the rail 3.

[0057] The weight of the housing 11, the viscosity of the silicone oil, and the amount added are set according to the corrugation frequency of the rail 3. The natural frequency of the suppression mechanism 1 is changed by changing the amount of silicone oil added and the number of the first counterweight ball 16 and the second counterweight ball 18, so that the natural frequency of the suppression mechanism 1 is close to or equal to the corrugation frequency of the rail 3, so that the corrugation mechanism resonates with the rail 3. In the resonant state, the corrugation mechanism can absorb and dissipate energy more effectively, thereby playing a better role in suppressing corrugation.

[0058] The first flexible rope 15 and the second flexible rope 17 have a certain degree of elasticity to accommodate the vibration of the first counterweight ball 16 and the second counterweight ball 18 as the suppressing liquid vibrates. The natural frequencies of the first counterweight ball 16 and the second counterweight ball 18 are close to or equal to the corrugation frequency, causing the first counterweight ball 16 and the second counterweight ball 18 to resonate, increasing the amplitude of the first counterweight ball 16 and the second counterweight ball 18, absorbing vibration energy, accelerating the dissipation of vibration energy, and improving the vibration suppression effect. During vibration, the suppressing agent also drives the first counterweight ball 16 and the second counterweight ball 18 to swing, further improving the vibration suppression effect. The first flexible rope 15 and the second flexible rope 17 are set vertically, which has a good suppression effect on both the lateral and vertical vibrations of the rail 3, reducing the corrugation phenomenon of the rail 3.

[0059] The vibration of silicone oil, the first counterweight ball 16, and the second counterweight ball 18 can also slow down the vibration propagation of noise, absorb the vibration energy of noise, and improve the noise reduction effect.

[0060] A connecting block 12 is provided between the housing 11 and the rail 3. The housing 11 on the suppressing mechanism 1 is fixed to the connecting block 12, and the connecting block 12 fixes several housings 11 together into a single structure. The side of the connecting block 12 closest to the rail 3 is adapted to the shape of the rail web of the rail 3, so that the connecting block 12 fits tightly against the rail web of the rail 3. The connecting block 12 is a rubber block. The housing 11 is made of metal to improve the rigidity of the housing 11.

[0061] like Figure 9 , Figure 10 , Figure 11 As shown. The fixing mechanism 2 includes a base 21, with support legs 22 fixedly mounted on the bottom of the base 21. Energy dissipation boxes 26 are arranged in a linear array on the upper surface of the base 21, and a first spring 28 supporting the energy dissipation boxes 26 is provided between the energy dissipation boxes 26 and the base 21. The two ends of the first spring 28 are fixedly connected to the energy dissipation boxes 26 and the base 21, respectively. The natural frequency of the fixing mechanism 2 is set to the wave frequency, and the stiffness of the first spring 28 is set according to the wave frequency to improve the absorption of vibration energy by the first spring 28.

[0062] like Figure 13As shown. Fixing plates 23 are fixedly installed on both sides of the base 21, and a support plate 24 for supporting the housing 11 is fixedly installed on the top of the fixing plates 23. A clamping structure for clamping the housing 11 is provided on the support plate 24. The clamping structure includes clamping plates 25, each corresponding to a housing 11. The clamping plates 25 are located above the support plates 24. Ear plates 225 are fixedly installed at the bottom of the clamping plates 25, located between the two support plates 24. The ear plates 225 are connected to the side wall of the energy consumption box 26 via a transmission rod 27, with both ends of the transmission rod 27 hinged to the ear plates 225 and the energy consumption box 26, respectively. The energy consumption box 26 moves the clamping plates 25 via the transmission rod 27, thereby clamping the housing 11 onto the web of the rail 3 via the clamping plates 25. The support plate 24 is provided with a limiting groove 224 that guides the horizontal sliding of the clamping plate 25. A protrusion adapted to the limiting groove 224 is fixedly provided at the bottom of the clamping plate 25. The protrusion is located in the limiting groove 224 and is slidably connected to the limiting groove 224. A rubber pad can be provided on the contact surface between the support plate 24 and the housing 11 to buffer vibration.

[0063] The base 21 is provided with a locking structure for locking the energy consumption box 26. The locking structure includes two locking units symmetrically arranged at the bottom of the energy consumption box 26. Each locking unit includes a rod 29 fixedly installed at the bottom of the energy consumption box 26, and the base 21 is provided with a socket 210 for inserting the rod 29. The base 21 is provided with a limiting hole 213 perpendicular to and communicating with the socket 210. A locking block 212 is slidably installed in the limiting hole 213, and a second spring 214 is provided between the limiting hole 213 and the locking block 212. The rod 29 is provided with a locking hole 211. Under the action of the second spring 214, the locking block 212 is inserted into the locking hole 211 to lock the rod 29 in the socket 210.

[0064] like Figure 12As shown. A power structure is provided on the base 21 to drive the locking block 212 to slide within the limiting hole 213. The power structure includes a slider 215. The locking block 212 has a through hole, and the slider 215 is slidably disposed within the through hole. The length of the through hole is greater than the width of the slider 215, satisfying the horizontal sliding requirement of the locking block 212. The base 21 has a slot to accommodate the slider 215, which is located within and slidably connected to the slot. A transmission ramp is provided at the top of the slider 215. A first ramp adapted to the transmission ramp of the slider 215 is provided within the through hole of the locking block 212. When the slider 215 moves downward, it drives the locking block 212 to slide out of the locking hole 211 via the transmission ramp and the first ramp. A sliding hole 216 is provided at the bottom of the slider 215, and a sliding plate 217 is located within and slidably connected to the sliding hole 216. The length of the sliding hole 216 is greater than the width of the slide plate 217, allowing the slider 215 to move up and down. The slide plate 217 has a transmission hole 218, and the sliding hole 216 has a second inclined surface that matches the inclined surface of the transmission hole 218. When the slide plate 217 slides horizontally, it drives the slider 215 downwards via the second inclined surface and the second inclined surface. The sliding plate 217 and slider 215 drive the locking block 212 to slide within the limiting hole 213, resulting in convenient operation and high transmission stability.

[0065] like Figure 14 As shown. The power structure can also be configured as follows: the locking block 212 is an L-shaped structure, and the sliding plate 217 is fixedly connected to the bottom end of the L-shaped locking block 212. The end of the limiting hole 213 away from the insertion hole 210 passes through the base 21, allowing the bottom end of the locking block 212 to extend out from the limiting hole 213 and slide within it. The sliding plate 217 directly drives the locking block 212 to slide. This power structure is simple, but the locking block 212 is a cantilever structure, resulting in slightly poor stability.

[0066] The ends of the slide plates 217 on the two locking units are fixedly connected by connecting plates 219. A slide rod 221 is fixedly installed in the middle of the connecting plate 219, and a positioning plate 220 is fixedly installed at the bottom of the base 21. The positioning plate 220 has a through hole for the slide rod 221 to pass through, and the slide rod 221 is slidably connected to the positioning plate 220. A third spring 222 is installed between the positioning plate 220 and the connecting plate 219, and the third spring 222 provides a restoring force for the slide plate 217. A push plate 223 is fixedly installed at the end of the slide rod 221 to facilitate the sliding of the slide rod 221, and a guide rail 226 is fixedly installed on the base 21 to guide the horizontal sliding of the slide plate 217.

[0067] for Figure 12The power structure pushes the push plate 223 inward. The push plate 223 drives the slide plate 217 to slide inward through the slide rod 221. The slide plate 217 drives the slider 215 to move downward through the transmission hole 218. The slider 215 drives the locking block 212 to move away from the insertion rod 29 through the transmission inclined surface. The locking block 212 slides out from the lock hole 211, and the first spring 28 resets, so that the suppression device can be removed from the rail 3.

[0068] for Figure 14 The power structure in the middle pulls the push plate 223 outward. The push plate 223 drives the slide plate 217 to slide outward through the slide rod 221. The slide plate 217 directly drives the locking block 212 to move away from the insertion rod 29. The locking block 212 slides out from the lock hole 211, the first spring 28 resets, and the suppression device can be removed from the rail 3.

[0069] like Figure 6 , Figure 7 , Figure 8 As shown, the energy dissipation box 26 is located directly below the rail 3. A top plate 227 is fixedly installed on the top of the energy dissipation box 26, and a rubber layer is fixedly installed on the upper surface of the top plate 227 to buffer vibration. Several third flexible ropes 228 are evenly arranged on the top plate 227, with adjacent rows of third flexible ropes 228 spaced apart. A third counterweight ball 229 is fixedly installed at the bottom of each third flexible rope 228. Since only the top end of each third flexible rope 228 is fixed to the top plate 227, the third counterweight ball 229 has a relatively high degree of freedom. When the energy dissipation box 26 drives the third counterweight ball 229 to vibrate via the third flexible rope 228, the third counterweight ball 229 will swing. Under the action of inertia, the swing of the third counterweight ball 229 lags behind the vibration direction of the energy dissipation box 26, so that some instantaneous swing directions of the third counterweight ball 229 are opposite to the instantaneous vibration direction of the energy dissipation box 26. The third counterweight ball 229 hinders the vibration of the energy dissipation box 26, increases energy consumption, which is conducive to improving the dissipation of vibration energy of the rail 3, reducing noise and vibration of the rail 3, and suppressing the corrugation of the rail 3.

[0070] The installation method of the above-mentioned rail corrugation suppression device includes the following steps:

[0071] S1. Fix the first counterweight ball 16 to the first flexible rope 15, fix the second counterweight ball 18 to the second flexible rope 17, fix the third counterweight ball 229 to the bottom end of the third flexible rope 228, fix the two ends of the first flexible rope 15 and the second flexible rope 17 to the inner wall of the box 11 respectively, and fix the top end of the third flexible rope 228 to the top plate 227.

[0072] S2. Inject the inhibitory liquid into the tank 11 through the liquid inlet 13 and then seal the liquid inlet 13.

[0073] S3. Place the base 21 below the rail 3, and place the box 11 and connecting block 12 on the support plate 24. Press down on the rail 3 or push the base 21 upward, compressing the first spring 28, which pushes the energy consumption box 26 to contact the bottom of the rail 3. Insert the insertion rod 29 into the insertion hole 210, and the locking block 212, under the action of the second spring 214, inserts into the locking hole 211, locking the energy consumption box 26.

[0074] S4. As the energy dissipation box 26 moves, the energy dissipation box 26 drives the clamping plate 25 to slide inward through the transmission rod 27. The clamping plate 25 clamps the box body 11 and the connecting block 12 at the web of the rail 3, thus completing the installation of the suppression device.

[0075] A comparative analysis was conducted on the initial state of the rails, the acceleration, vertical wheel-rail force, rail displacement, and rail surface irregularities of rails with and without the suppression device described in this embodiment. The analysis results are as follows: Figures 15-18 As shown. Figures 15-18 The wear suppressor refers to the suppression device described in this embodiment.

[0076] Figure 15 This describes the magnitude of the vertical vibration acceleration of the rail; a larger value indicates more severe vertical vibration. For example... Figure 15 As shown, after the suppression device is installed on the rail, the vertical vibration acceleration of the rail is effectively reduced. When the rail vibrates, the inhibitor in the suppression device of this embodiment generates resistance due to viscosity, consuming vibration energy; the oscillation of the first and second counterweight balls during vibration also accelerates energy dissipation; the elasticity of the first and second flexible ropes allows the counterweight balls to better adapt to vibration, and their vertical arrangement suppresses vibration from multiple directions, thereby effectively reducing the vibration amplitude of the rail.

[0077] Figure 16 This describes the magnitude of the forces acting on the rails during operation; the magnitude of these forces directly reflects the strength of the interaction between the wheel and rail. For example... Figure 16 As shown, after the suppression device is installed on the rail, the force curve of the rail is lower than that without the wear suppressor. This fully demonstrates that installing the suppression device described in this embodiment on the rail can effectively reduce the force on the rail during operation. The energy dissipation box in the suppression device is located directly below the rail, and the suppression mechanism is symmetrically arranged on both sides of the rail web. During train operation, interaction forces are generated between the wheel and the rail, causing stress on the rail. The suppression device, through the energy dissipation box and the suppression mechanism, disperses and consumes some of the energy, reducing the interaction force between the wheel and the rail. The first suppression layer, the second suppression layer, and the inhibitor in the suppression mechanism work together to change the force transmission path and magnitude, reducing the force transmitted to the rail and thus alleviating the degree of rail corrugation.

[0078] Figure 17 This describes the magnitude of the displacement that occurs in the rail during operation. The magnitude of the displacement reflects the degree of positional change of the rail under the influence of vibration. For example... Figure 17 As shown, the installation of the damping device on the rail significantly reduces rail displacement. The fixing mechanism securely holds the damping mechanism to the rail, while the damping mechanism suppresses rail vibration from both sides. When the rail vibrates, the fixing and damping mechanisms work together: the fixing mechanism provides stable support, and the damping mechanism reduces the vibration amplitude by consuming vibration energy, thereby reducing vibration-induced displacement. The counterweight balls and damping agents in the damping mechanism absorb and dissipate energy during vibration, controlling rail vibration, reducing displacement, and enhancing rail stability.

[0079] Figure 18 This value measures the smoothness of the rail surface; the higher the value, the more uneven the rail surface. For example... Figure 18 As shown, after the suppression device was installed on the rail, the rail surface unevenness curve was significantly lower than the curve without the wear suppressor. This clearly demonstrates the significant effect of the suppression device in improving rail surface unevenness. Rail corrugation leads to an increase in rail surface unevenness. The suppression device described in this embodiment effectively reduces rail surface wear by suppressing rail vibration and stress. Under the combined action of the suppression mechanism and energy dissipation box in the suppression device, the vibration acceleration, stress, and displacement are reduced, thereby lessening the degree of wear on the rail surface during train operation, thus reducing rail surface unevenness and extending the service life of the rail.

[0080] Therefore, the rail corrugation suppression device and installation method described in this invention can solve the problem of poor performance of existing rail corrugation suppression devices in reducing rail vibration and noise.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
