Description

Technical Field

[0001] This utility model relates to the field of rail transit equipment technology, specifically a mounting base for a grinding wheel on a rail vehicle. Background Technology

[0002] The mounting base for the grinding wheel of a rail vehicle belongs to the field of rail transit equipment technology, specifically to the braking and wheel-rail maintenance of rail vehicles. It is mainly used in the wheel grinding system of rail vehicles such as urban rail trains and high-speed trains. It is the core load-bearing and positioning component connecting the grinding wheel to the vehicle bogie. This base is a key structural component for realizing the wheel-rail compatibility maintenance of rail vehicles. Its core function is to provide a stable mounting foundation for the grinding wheel and ensure grinding accuracy. Existing mounting bases have certain defects.

[0003] For example, a grinding tool for high-speed rail with high wear resistance, as described in application number CN202221849981.3, includes a grinding tool body. A buffer mechanism is fixedly connected to the top of the grinding tool body. A mounting plate is welded to the top of the buffer mechanism. Mounting grooves are provided on both the front and rear sides of the mounting plate. A wear-resistant bottom shell is welded to the bottom of the grinding tool body. The grinding tool body includes a grinding tool base plate. Limiting plates are welded to the left and right sides of the top of the grinding tool base plate, and the top of the limiting plates extends into the inner cavity of the buffer mechanism. This utility model, through the coordinated use of the grinding tool body, mounting plate, mounting groove, vertical plate, movable plate, cavity, buffer spring, limiting groove, connecting plate, grinding tool base plate, limiting plate, wear-resistant layer, corrosion-resistant layer, and bottom shell body, provides a buffering function, enabling the worn grinding tool to fully contact the wheel, resulting in better wear resistance and extended service life. However, the mounting base is prone to deformation due to vibration, which can lead to local cracks. The grinding ball may also cause uneven grinding, breakage, and noise pollution due to vibration. Furthermore, the base is susceptible to corrosion in harsh environments, resulting in a short lifespan. Corrosion products can also affect installation accuracy and threaten operational safety.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a mounting base for a grinding wheel of a rail vehicle. Utility Model Content

[0005] The purpose of this utility model is to provide a mounting base for a grinding wheel on a rail vehicle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mounting base for a grinding wheel of a rail vehicle, comprising a base body and a shock-absorbing and noise-reducing mechanism. The shock-absorbing and noise-reducing mechanism is fixedly connected inside the base body, and the shock-absorbing and noise-reducing mechanism includes a noise-reducing frame fixedly connected to the inner wall of the base body. A shock-absorbing rod is fixedly connected inside the base body, and a reinforcing plate is fixedly connected to the top of the shock-absorbing rod. A rubber pad is fixedly connected to the top of the reinforcing plate.

[0007] Preferably, an L-shaped fixing plate is fixedly connected inside the base body, and an anti-corrosion mechanism is fixedly connected to the bottom of the base body.

[0008] Preferably, the anti-corrosion mechanism includes a bottom zinc-chromium coating fixedly connected to the bottom of the base body, and a middle layer of epoxy glass flakes fixedly connected to the bottom of the bottom zinc-chromium coating. A top layer of polyvinyl fluoride is fixedly connected to the bottom of the middle layer of epoxy glass flakes.

[0009] Preferably, the base body has a dust collection frame inside, and a dust collection drawer is slidably connected to the inner surface of the dust collection frame.

[0010] Preferably, the inner surface of the L-fixing plate is threaded with a fastening nut, and a fixing block is provided on the top of the L-fixing plate.

[0011] Preferably, the fixing block has a positioning hole inside, and a grinding support is fixedly connected to one side of the fixing block.

[0012] Preferably, a connecting plate is fixedly connected to the top of the grinding tray, and the connecting plate has mounting holes inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a shock-absorbing and noise-reducing mechanism, not only absorbs high-frequency noise during grinding, but its frame structure also enhances the rigidity of the inner wall of the base body, reducing deformation caused by resonance. The shock-absorbing rod and reinforcing plate can attenuate the longitudinal impact force generated by grinding. Combined with the stress-dispersing effect of the reinforcing plate, it prevents the base body from cracking due to excessive local stress, ensuring that the base can withstand the grinding load for a long time without deformation. The top rubber pad is in direct contact with the grinding ball, and further absorbs the remaining vibration through its own elastic deformation, making the contact pressure between the grinding ball and the wheel tread more uniform, reducing the problem of uneven grinding caused by vibration, reducing noise pollution during the operation of rail vehicles, not only improving the installation stability of the base body, but also reducing the risk of the grinding ball cracking due to severe vibration, extending the service life of the grinding ball, and indirectly reducing vehicle maintenance costs; 2. This utility model provides progressive protection for the mounting base through the setting of the anti-corrosion mechanism, which comprehensively enhances the adaptability of the base in harsh track environments. The three-layer protective coating works synergistically to greatly improve the salt spray resistance of the base, extend the service life of the base, reduce the base replacement cost caused by corrosion, and at the same time avoid the accumulation of corrosion products affecting the installation accuracy of the grinding ball, ensure the stability of grinding operations, and improve the safety of rail vehicle operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As shown in Figures 1-3, a mounting base for a grinding wheel on a rail vehicle includes a base body 1 and a vibration damping and noise reduction mechanism 2. The vibration damping and noise reduction mechanism 2 is fixedly connected inside the base body 1, and includes a noise reduction frame 201 fixedly connected to the inner wall of the base body 1. A vibration damping rod 202 is fixedly connected inside the base body 1, and a reinforcing plate 203 is fixedly connected to the top of the vibration damping rod 202. A rubber pad 204 is fixedly connected to the top of the reinforcing plate 203. The base body 1 serves as the load-bearing core, and the noise reduction frame 201, fixed to the inner wall of the base body 1, can absorb high-frequency noise generated during operation and reduce sound wave transmission. The vibration damping rod 202 is vertically connected to the base body 1 and the reinforcing plate 203, which can buffer the longitudinal impact force during operation. The reinforcing plate 203 enhances the structural rigidity and prevents deformation of the base body 1. The top rubber pad 204 directly contacts the grinding wheel, further attenuating vibration and isolating friction noise. The cooperation of these components improves the stability of the base body 1 and extends the service life of the grinding wheel.

[0018] like Figure 4 As shown, an L-shaped fixing plate 3 is fixedly connected inside the base body 1, and an anti-corrosion mechanism 4 is fixedly connected to the bottom of the base body 1. The anti-corrosion mechanism 4 is characterized by including a bottom zinc-chromium coating 401 fixedly connected to the bottom of the base body 1, a middle layer of epoxy glass flakes 402 fixedly connected to the bottom of the bottom zinc-chromium coating 401, and a top layer of polyvinyl fluoride 403 fixedly connected to the bottom of the middle epoxy glass flakes 402. The bottom zinc-chromium coating 401 is directly attached to the bottom of the base body 1. Due to the cathodic protection characteristics of zinc-chromium, it preferentially reacts with corrosive media, blocking the rust path of the metal substrate of the base body 1. The middle epoxy glass flakes 402 are tightly attached to the bottom coating, and their interlaced structure can fill the gaps in the coating, reducing the penetration of corrosive factors such as moisture and salt, while enhancing the overall impact resistance of the coating. The top layer of polyvinyl fluoride 403, as the outermost protective layer, possesses excellent weather resistance and chemical stability, resisting acid and alkali corrosion and ultraviolet aging, significantly extending the service life of the base body 1.

[0019] Furthermore, a dust collection frame 5 is provided inside the base body 1, and a dust collection drawer 6 is slidably connected to the inner surface of the dust collection frame 5. The L-shaped fixing plate 3 has a threaded fastening nut 7 on its inner surface, and a fixing block 8 is provided on the top of the L-shaped fixing plate 3. The dust collection drawer 6 can collect metal shavings and dust generated during operation, and its pull-out design allows for quick cleaning, preventing dust accumulation from affecting component operation. The L-shaped fixing plate 3 and the fixing block 8 form a positioning structure, which, together with the fastening nut 7 on the inner surface, can precisely lock the base body 1 to the vehicle bogie, preventing positioning deviation due to loosening during operation. The dust collection and fixing components respectively ensure the cleanliness of the base and the stability of the installation, improving overall operational reliability.

[0020] Furthermore, the fixing block 8 has a positioning hole 9 inside, and a grinding support 10 is fixedly connected to one side of the fixing block 8. A connecting plate 11 is fixedly connected to the top of the grinding support 10, and an installation hole 12 is opened inside the connecting plate 11. The positioning hole 9 inside the fixing block 8 can be used to insert a positioning pin to accurately align with the bogie or other components, ensuring that the fixing block 8 is installed without deviation. The grinding support 10 on one side serves as the direct bearing structure for the grinding ball, and the installation hole 12 of the top connecting plate 11 is used to fix the connecting components to prevent displacement or shaking during operation.

[0021] Working Principle: When using the grinding wheel mounting base for this rail vehicle, firstly, the worker uses the base body 1 as the basic carrier. Its external anti-corrosion mechanism 4 then comes into play. The bottom layer of zinc-chromium coating 401 adheres to the surface of the base body 1, forming cathodic protection. The middle layer of epoxy glass flakes 402 fills gaps and prevents corrosive media penetration. The surface layer of polyvinyl fluoride 403 resists external acids, alkalis, and ultraviolet rays. These three layers work together to protect the base body 1 from corrosion. Simultaneously, the grinding wheel support 10 is locked and fixed to the vehicle bogie through the mounting holes 12 on the fixing plate 11. The fastening nut passes through the internal positioning hole 9 of the fixing block 8 and the L-plate, ensuring that the base body 1 is installed without deviation. Then, when the rail vehicle runs and the grinding wheel rubs against the wheel tread, the shock absorption and noise reduction mechanism 2 inside the base body 1 activates. The shock absorber 202 buffers longitudinal impact, the top reinforcing plate 203 enhances structural rigidity to prevent deformation, the rubber pad 204 further attenuates vibration and isolates friction noise, and the noise reduction frame 201... The base absorbs high-frequency noise, reducing operational noise pollution. Finally, the metal shavings and dust generated during operation fall into the dust collection frame 5 inside the base body 1. The dust collection drawer 6 collects the dust and can be pulled out for cleaning at any time, preventing dust accumulation from affecting the operation of the components. This is the working principle of the rail vehicle grinding wheel mounting base.
