These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0043] As mentioned in the background technology, with the application of green, safe and environmentally friendly concepts in urban rail transit vehicles, vehicle design companies need a lightweight bogie to improve the overall weight of the vehicle. The lightweight advantage of the built-in axle box bogie has once again come into view. After the axle box is built in, the axle length is shortened, the internal space layout of the bogie is more compact, and the external space is significantly reduced.

[0044] Meanwhile, as train speeds and mileage continue to increase, train service conditions become more severe, and fatigue fractures of bogie auxiliary components such as stone sweepers caused by random vibrations become particularly prominent.

[0045] To ensure the structural strength of the train's stone sweeper within the built-in axle box bogie, existing technologies typically use methods such as increasing the thickness of the stone sweeper's mounting structural components. However, as the thickness of the mounting structural components increases, the weight of the train's stone sweeper also increases, which does not conform to the concept of lightweight design and increases manufacturing costs.

[0046] Therefore, in order to meet the design requirements of the built-in axle box bogie and solve the safety and reliability issues of the stone sweeper, designers urgently need a train stone sweeper that is safer and can meet the requirements of lightweight design and can be installed with the built-in axle box bogie.

[0047] In view of this, this embodiment provides a train stone sweeper. Through the hollow design of the connecting pipe, the train stone sweeper reduces weight while maintaining strength, which meets the design requirements of modern lightweight trains. The matching design of the connecting pipe and the mounting port makes the installation and replacement of the stone sweeper faster and easier. Different trains can be adapted by simply changing the size of the mounting parts, which increases the flexibility and versatility of the design.

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] refer to Figures 1-3 This application provides a train stone sweeper, including a mounting base 100 and a stone sweeping structure 200.

[0051] The first end of the mounting base 100 is used to mount the axle box bogie, and the second end of the mounting base 100 extends downward, with a mounting port 101 provided at the second end of the mounting base 100.

[0052] The stone sweeping structure 200 includes a connecting pipe 210 and a stone sweeping component 220 connected to each other. The connecting pipe 210 is hollow and passes through the mounting port 101. The connecting pipe 210 is fixedly connected to the mounting base 100.

[0053] The stone sweeping component 220 is located below the connecting pipe 210. The stone sweeping component 220 is connected to the mounting base 100 through the connecting pipe 210. The stone sweeping component 220 is used to sweep away debris on the track.

[0054] It is understood that the first end of the mounting base 100 is used to install on the bogie, ensuring that the stone sweeper can be firmly fixed to the bottom structure of the train; the design of the mounting port 101 of the mounting base 100 allows the mounting base 100 to achieve a quick and stable connection with the connecting pipe 210; the design of the mounting base 100 takes into account compatibility with the built-in axle box bogie, ensuring the overall stability of the stone sweeper; the hollow design of the connecting pipe 210 provides sufficient installation strength while significantly reducing the overall weight of the stone sweeper, which is in line with the concept of lightweight design; the stone sweeping component 220 is in direct contact with the track and is responsible for clearing obstacles on the track, ensuring the safe operation of the train.

[0055] It should be noted that the tubular structure has excellent strength and rigidity when subjected to axial and radial loads. This means that the connecting pipe 210 can provide sufficient strength to support the operation of the sweeping component 220 and the vibration of train operation while maintaining a lightweight design. Due to the reduction in the amount of material used, the cost of manufacturing the connecting pipe 210 is also reduced accordingly. The tubular design gives the connecting pipe 210 an arc-shaped outer wall, which makes it easier to match with the mounting port 101 of the mounting base 100, simplifying the installation and disassembly process.

[0056] The hollow design of the connecting pipe 210 reduces the weight of the train sweeper while maintaining its strength, meeting the lightweight design requirements of modern trains. The matching design of the connecting pipe 210 and the mounting port 101 makes the installation and replacement of the sweeper faster and easier. Different trains can be adapted simply by changing the size of the parts of the mounting base 100, increasing the flexibility and versatility of the design. Due to the reduction in the amount of materials used, the overall manufacturing cost is reduced, and the energy consumption during train operation is also reduced.

[0057] Specifically, in the embodiment of this application, the wheel-rail excitation of the built-in axle box bogie of the train sweeper is greatly attenuated through the transmission of a series of springs at the end of the frame, the vibration acceleration level is reduced, and the service life of the train sweeper is improved.

[0058] In some possible implementations, the length of the connecting pipe 210 is greater than the width of the mounting base 100 in the extending direction of the connecting pipe 210, and both ends of the connecting pipe 210 extend out of the mounting base 100.

[0059] It is known that the length of the connecting pipe 210 is greater than the width of the mounting base 100, and both ends extend beyond the mounting base 100. This design increases the support area and contact surface of the connecting pipe. Through the extended structure, the connecting pipe can better distribute and withstand the load and vibration from the sweeper 220. Compared to increasing strength by increasing thickness, the design of extending the connecting pipe 210 enhances strength through geometric structure without increasing material thickness, reducing material usage and thus reducing weight, which is in line with the concept of lightweight design. Since both ends of the connecting pipe 210 extend beyond the mounting base 100, this design allows for more adjustment space during installation, adapting to different bogie specifications. This flexibility simplifies the installation process and reduces the difficulty of adapting to different train models. Because there are extra stress points at the connection between the two ends of the connecting pipe 210 and the mounting base 100, it is convenient to fix the two ends of the connecting pipe 210 to the mounting base 100. The extended design of the connecting pipe 210 helps to improve its resistance to torsional forces, which is beneficial for the sweeper to resist possible lateral forces and vibrations during operation.

[0060] In this way, by increasing the length of the connecting pipe 210 and extending both ends of it beyond the mounting base 100, the overall structure exhibits higher safety when subjected to external impacts and vibrations, thereby improving the strength and stability of the overall structure; since there is no need to increase the material thickness to increase strength, the manufacturing cost is reduced, and material waste is also reduced.

[0061] In some possible implementations, the stone sweeping component 220 includes a fixing part 221 and a contact part 222, with the fixing part 221 connected to the end of the connecting pipe 210.

[0062] The contact portion 222 is disposed at the bottom end of the fixing portion 221, and at least a portion of the contact portion 222 is located below the fixing portion 221. The contact portion 222 is used to contact debris on the track.

[0063] It is understood that the fixing part 221 is connected to the end of the connecting pipe 210 to ensure that the sweeping part 220 can be firmly attached to the connecting pipe 210. Through this connection, the fixing part 221 provides stable support, so that the sweeping part 220 can remain stable during train operation and is not easy to fall off or shift. This design helps to effectively transmit the force from the contact part 222 to the connecting pipe 210, thereby improving the strength and stability of the overall structure. The contact part 222 is the direct contact surface between the sweeper and the track debris. Its design needs to consider wear resistance and effective sweeping ability. By setting the contact part 222 below the fixing part 221, the design ensures that the contact part can flexibly contact the track surface without affecting the stability of the fixing part.

[0064] By dividing the sweeping component 220 into a fixed part and a contact part, designers can optimize material usage and reduce unnecessary weight while ensuring strength. The separate design allows the use of different materials to optimize strength and wear resistance separately. The combination of the stable connection of the fixed part 221 and the effective sweeping function of the contact part 222 improves the safety and reliability of the train sweeper under various operating conditions. Since the contact part 222 is the part that directly contacts the track, it wears out quickly. The separate design allows the contact part to be replaced individually, reducing maintenance costs and time.

[0065] In some embodiments, the contact portion 222 may be made of a flexible material. Specifically, the contact portion 222 is made of a rubber composite material. Rubber composite materials have good elasticity and wear resistance, and can effectively absorb impact forces.

[0066] Contact part 222 can also be made of carbon fiber composite material. Carbon fiber composite material is extremely light and has high strength and wear resistance, which meets the requirements of lightweight design.

[0067] It should be noted that as long as the contact part 222 can clean up stones and other debris on the running path, the specific material of the contact part 222 is not subject to many restrictions in this embodiment.

[0068] In some possible implementations, the fixing part 221 is configured as a fixing plate, which includes a first part and a second part connected to each other.

[0069] The first part of the fixing plate is connected to the end of the connecting pipe 210, the second part of the fixing plate is connected to the contact part 222, and an included angle is provided between the first part of the fixing plate and the second part of the fixing plate.

[0070] It can be understood that the first part of the fixing plate provides stable support, enabling the entire stone sweeping component 220 to remain stable during train operation. The force from the contact part 222 can be effectively transmitted to the connecting pipe 210, thereby improving the strength and stability of the overall structure. An angle is provided between the first part and the second part of the fixing plate. This angle design can optimize the contact angle between the contact part 222 and the track, improve the sweeping efficiency, and the presence of the angle can also help buffer and disperse the impact force from the track, reduce the direct impact on the fixing plate and the connecting pipe 210, thereby extending the service life of the equipment.

[0071] For example, the included angle between the first part and the second part of the fixing plate can be set to be greater than or equal to 80° and less than or equal to 180°.

[0072] For example, the included angle between the first part of the fixing plate and the second part of the fixing plate can be set within any angle range of 80°-90°, 90°-100°, 100°-110°, 110°-120°, 120°-130°, 130°-140°, 140°-150°, 150°-160°, 160°-170°, and 170°-180°, so that the second part of the fixing plate fixes the contact part 222 to a suitable stone-sweeping angle.

[0073] Specifically, the included angle between the first part of the fixing plate and the second part of the fixing plate can be set to 90°. The 90° included angle is easy to manufacture and assemble; the right angle design can provide higher structural strength and stability, especially when subjected to vertical and horizontal loads; it can effectively transfer the force from the contact part 222 to the connecting pipe 210 and the first part of the fixing plate, reducing stress concentration.

[0074] The angled design of the fixed plate improves structural strength and stability without increasing material thickness, which aligns with the concept of lightweight design. The angled design optimizes the contact angle between the contact part 222 and the track, making the cleaning process more efficient and reducing possible resistance and wear during cleaning. The presence of the angle helps to buffer and disperse impact forces, reducing direct damage to the structure and improving the durability and safety of the equipment.

[0075] In some possible implementations, the first part of the fixing plate is provided with a reinforcing part 223, which is fixedly connected to the connecting pipe 210.

[0076] An angle is provided between the reinforcing part 223 and the first part of the fixing plate.

[0077] It is known that by adding the reinforcing part 223, the first part of the fixing plate gains additional support and strength, which can effectively disperse and bear the load and vibration from the sweeping stone 220, reduce stress concentration, and improve the overall structure durability; an angle is provided between the reinforcing part 223 and the first part of the fixing plate, and the presence of the angle helps to optimize the force transmission path, so that the reinforcing part 223 can more effectively disperse the stress from the connecting pipe 210.

[0078] By setting the reinforcing part 223, the strength of the first part of the fixing plate is significantly improved, thereby enhancing the structural strength of the entire train sweeper; the reinforcing part 223 provides additional strength support, so that it is not necessary to increase the strength by increasing the material thickness, thereby reducing the overall weight and conforming to the concept of lightweight design.

[0079] In some possible implementations (not shown in the figures for this embodiment), an opening is provided below the mounting port 101, and the reinforcing part 223 passes through the opening.

[0080] It is understood that an opening is provided below the mounting port 101, allowing the reinforcing part 223 to pass through it. This design enables the reinforcing part 223 to directly connect and support the interior of the mounting structure. Through the opening, the reinforcing part 223 can be more tightly integrated with the mounting structure, thereby improving the overall structural strength and stability. By passing through the opening, the reinforcing part 223 can effectively distribute and bear the load and vibration from the sweeping stone component 220. This design reduces stress concentration and improves the durability and reliability of the overall structure.

[0081] In some possible implementations, the extending direction of the connecting pipe 210 is parallel to the extending direction of the mounting port 101.

[0082] The connecting pipe 210 is provided with at least one fixing structure, and the connecting pipe 210 is fixedly connected to the mounting base 100 through the fixing structure.

[0083] The parallel alignment of the extension direction of the connecting pipe 210 with that of the mounting port 101 ensures that the connecting pipe 210 maintains the same orientation as the mounting base 100 during installation, thus simplifying the installation process. This design reduces stress and torsion between the connecting pipe 210 and the mounting base 100, ensuring the stability and consistency of the structure. The fixed structure provides additional support and stability, ensuring that the connecting pipe 210 can be firmly attached to the mounting base 100. The connecting pipe 210 can also effectively withstand and disperse the load and vibration from the sweeping stone component 220, reducing stress concentration and improving the overall durability of the structure.

[0084] In some possible implementations, the contact portion 222 is movably connected to the second part of the fixed plate, and the contact portion 222 is movable relative to the second part of the fixed plate in a vertical direction.

[0085] The contact portion 222 is provided with a locking portion 224, and the contact portion 222 is fixed to the second part of the fixing plate by the locking portion 224.

[0086] It is understood that the movable connection between the contact part 222 and the fixing part 221 allows the contact part 222 to adapt to the unevenness and changes of the track surface, improving cleaning efficiency and effect; the vertical movement capability allows the contact part 222 to adjust according to the height changes of the track, ensuring that the best cleaning contact is always maintained, improving the adaptability and cleaning efficiency of the train sweeper; the locking part 224 provides the ability to fix the contact part 222 in a specific position when needed, ensuring the stability of the contact part 222 during normal operation, and quickly releasing and re-fixing the contact part 222 when maintenance or adjustment is required, improving the convenience of operation.

[0087] The movable connection and vertical movement capability allow the contact part 222 to adapt to different track conditions, improving cleaning efficiency and equipment adaptability; the locking part 224 ensures the stability of the contact part 222 during operation and reduces the risk of damage caused by vibration or impact.

[0088] Specifically, the locking part 224 includes a stop washer and a fixing bolt. The second part of the fixing plate has a vertical moving groove. The fixing bolt passes through the stop washer and then passes through the moving groove and the contact part 222 in sequence. The side of the contact part away from the stop washer is fixed with a nut to clamp the contact part 222 onto the second part of the fixing plate. The height of the contact part 222 on the second part of the fixing plate can be adjusted by loosening the nut.

[0089] In some possible implementations, the mounting base 100 includes a first cover plate 110 and a second cover plate 120 connected to each other, the first cover plate 110 and the second cover plate 120 forming a receiving cavity, and at least one of the first cover plate 110 and the second cover plate 120 is used to connect the bogie.

[0090] At least one support plate 130 is provided inside the cavity, and the support plate 130 is connected to the first cover plate 110 and the second cover plate 120; an installation opening 101 is formed between the bottom end of the support plate 130 and the inner wall of the cavity.

[0091] It is known that the first cover plate 110, the second cover plate 120 are connected, the support plate 130, and the connecting pipe 210 form a cavity, forming a box beam structure. The box beam structure significantly increases the lateral stiffness of the mounting base 100, thereby increasing the low-order natural frequency of the structure, enabling it to avoid the main frequency of the line (50Hz-60Hz), reducing the vibration amplitude of the structure during operation, and thus reducing the damage to the train's stone sweeper. The support plate 130 provides structural support, enhancing the overall strength and rigidity of the mounting base 100.

[0092] The modular design of the mounting base 100 and the stone sweeping structure 200 enables rapid production of the train stone sweeper structure, thereby reducing manufacturing costs.

[0093] Specifically, the first cover plate 110, the second cover plate 120, and the support plate 130 are connected by welding. The connecting pipe 210 is connected to the mounting port 101 and the fixing part 221 by welding. The reinforcing part 223 is also connected to the first part of the fixing plate and the connecting pipe by welding. The welding process provides a strong and reliable connection, enhances the strength and stability of the overall structure, and can better withstand the loads and vibrations during operation.
