TECHNICAL FIELD

[0001] The present application relates to the field of railway track technology, in particular to a modular splicing type high-speed frog. BACKGROUND

[0002] The frog is a key functional component in the railway track system for realizing train turning and lane changing, is the "heart" of the turnout structure, and plays a core role in building a transition channel between two intersecting tracks to guide the wheels to smoothly transfer from one track to another track and bear the wheel-rail impact load during train turning, and its performance is directly related to train safety and line maintenance cost.

[0003] The overall structure of the existing high-speed frog causes the need for replacement of the entire group when local damage occurs, which not only requires the track to be stopped and personnel to be dispatched for repair and replacement, but also seriously affects the transportation efficiency, reduces the work efficiency, causes resource waste, and is difficult to meet various size requirements.

[0004] Therefore, it is necessary to provide a modular splicing type high-speed frog to solve the above technical problems. SUMMARY

[0005] The present application aims to provide a modular splicing type high-speed frog to solve the problems in the background art, and the technical solution of the present application provides a solution significantly different from the prior art to solve the technical problem that the prior art solution is too single.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a modular splicing type high-speed frog, comprising a wing rail base body, a detachable buffer base body is installed at one end of the side edge of the concave surface of the wing rail base body, a load bearing base body is installed on the opposite side of the two buffer base bodies, a separable connecting base body is installed at the other end of the side edge of the wing rail base body, and a fixing mechanism for stabilizing the load bearing base body is arranged on the top of the connecting base body.

[0007] Preferably, a groove one is equidistantly arranged on the parallel end of the side edge of the concave surface of the wing rail base body, a splicing assembly for stabilizing the buffer base body is installed inside the groove one, a groove two is arranged on the inclined end of the side edge of the concave surface of the wing rail base body, and a limiting block is arranged inside the groove two and installed on the inclined end of the buffer base body.

[0008] Preferably, the splicing assembly comprises a limiting plate equidistantly installed at the end of the buffer base body away from the load bearing base body, tooth grooves are arranged on both sides of the limiting plate, tooth plates are installed on both sides of the limiting plate, and only the two tooth plates at the most two ends are in a fixed state.

[0009] Preferably, connecting blocks are installed on the front and rear sides of the horizontal end of the tooth plate, mounting plates are connected to the other end of the connecting blocks, and clamping blocks are arranged between the two mounting plates.

[0010] Preferably, the ends of the two sets of wing rail bases away from the buffer base are provided with threaded holes that penetrate into the interior of the limiting plate, and a screw is installed inside the threaded hole.

[0011] Preferably, the buffer base has a positioning groove extending toward the wing rail base, and a positioning block adapted to the positioning groove is installed on one side of the top of the connecting base.

[0012] Preferably, the fixing mechanism includes a fixing plate one that is equidistantly installed on the side of the wing rail base. A long plate that is fixed in the extension direction of the buffer base is provided on the top outer side of the fixing plate one. A fixing plate two is equidistantly installed on the side of the long plate near the wing rail base. The fixing plate one and the fixing plate two are fixed together by bolts.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In terms of operational stability and safety, this modular splicing high-speed frog significantly improves performance through the synergistic effect of multiple modules: the dual positioning and screw locking structure formed during the module assembly stage ensures that the connection between the buffer base and the wing rail base is secure. When the train passes, the buffer base absorbs the impact energy, and the intermediate elastic tooth plate buffers the load through slight deformation. Combined with the positioning fit between the connecting base and the buffer base, and the uniform fastening of the fixing mechanism, it effectively avoids displacement and local deformation of the load-bearing base, ensures smooth wheel-rail contact, greatly reduces impact noise and wear, and reduces stress concentration damage to components. It significantly improves the overall fatigue resistance and service life of the frog, providing a reliable guarantee for the safe passage of high-speed trains. 2. When a vulnerable component malfunctions, this invention eliminates the need to disassemble the entire frog. Instead, it allows for the separation and replacement of the damaged buffer or load-bearing base simply by unscrewing the bolts of the fixing mechanism, removing the long plate, and disassembling the screws at the end of the wing rail base. The new module, with its positioning structure and splicing components, can be quickly and accurately reset, and maintenance can be completed by locking it with screws and bolts. This significantly reduces downtime for maintenance, decreases the workload of maintenance personnel, and avoids the need to replace the entire frog if only a part is damaged. This significantly reduces spare parts costs and overall maintenance costs, and improves the operational efficiency of railway lines. Attached Figure Description

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

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0018] Please see Figures 1-7A modular, splicing high-speed frog includes a wing rail base 1, a detachable buffer base 2 installed on one side of the concave surface of the wing rail base 1, a bearing base 3 installed on the facing side of the two sets of buffer bases 2, and a detachable connecting base 4 installed on the other side of the wing rail base 1. A fixing mechanism 5 for stabilizing the bearing base 3 is provided on the top of the connecting base 4. By disassembling the frog into a modular structure of wing rail base 1, detachable buffer base 2, bearing base 3, connecting base 4 and fixing mechanism 5, the structural limitations of traditional integral frogs are broken. When vulnerable parts such as buffer base 2 and bearing base 3 are worn or damaged, it is not necessary to replace the entire frog. Only the damaged module needs to be disassembled and replaced, which greatly reduces the cost of spare parts and the workload of replacement. At the same time, the fixing mechanism 5 can ensure the stability of the bearing base 3 when high-speed trains pass, avoiding traffic safety hazards caused by displacement of the bearing base 3.

[0019] like Figures 1-7 As shown, groove 1 (6) is equidistantly provided on the parallel side of the concave surface of the wing rail base 1. The splicing component of the stable buffer base 2 is installed inside the groove 1 (6). Groove 2 (7) is provided on the inclined side of the concave surface of the wing rail base 1. The limiting block 8 installed on the inclined end of the buffer base 2 is provided inside the groove 2 (7). The groove 1 (6) on the parallel side of the wing rail base 1 provides installation space for the splicing component, ensuring the stability of the splicing component on the buffer base 2. The groove 2 (7) on the inclined side cooperates with the limiting block 8 of the buffer base 2 to limit the buffer base 2 from the inclined direction, preventing the buffer base 2 from shifting along the inclined direction under the impact load of the train. The dual positioning structure improves the stability of the connection between the buffer base 2 and the wing rail base 1, ensures the smoothness of wheel-rail contact, and reduces wheel-rail impact noise and wear.

[0020] like Figures 1-7 As shown, the splicing assembly includes a limiting plate 9 equidistantly installed at one end of the buffer base 2 away from the bearing base 3. The limiting plate 9 has toothed grooves 10 on both sides and toothed plates 11 installed on both sides of the limiting plate 9. Only the two toothed plates 11 at the very end are fixed. The limiting plate 9 engages with the toothed plates 11 through the toothed grooves 10 to achieve a precise connection between the buffer base 2 and the wing rail base 1, ensuring the accuracy of the connection position. The design that only the toothed plates 11 at the very end are fixed allows the middle toothed plate 11 to have a certain elastic adjustment space. Under the impact load generated by the passing high-speed train, it can absorb part of the impact force through small deformation, reduce stress concentration damage to the connection structure between the limiting plate 9 and the toothed plate 11, extend the service life of the splicing assembly, and avoid the risk of component breakage caused by rigid connection.

[0021] like Figures 1-7As shown, connecting blocks 12 are installed on the front and rear sides of the horizontal end of the toothed plate 11. The other end of the connecting block 12 is connected to the mounting plate 13. A snap-fit ​​block 14 is provided between the two sets of mounting plates 13. The connecting block 12 connects the toothed plate 11 and the mounting plate 13 into a whole, so that the force on the toothed plate 11 can be transmitted to the mounting plate 13, dispersing the local force on the toothed plate 11 and reducing the probability of damage to the toothed plate 11 due to excessive force at a single point. The snap-fit ​​block 14 between the two sets of mounting plates 13 can further enhance the structural stability of the mounting plate 13, prevent the mounting plate 13 from deforming or misaligning when under force, thereby ensuring the overall connection strength of the splicing assembly, ensuring that the buffer base 2 does not loosen during long-term use, and maintaining the normal working state of the turnout.

[0022] like Figures 1-7 As shown, the ends of the two sets of wing rail bases 1 away from the buffer base 2 are provided with screw holes 17 that penetrate into the interior of the limiting plate 9. Screws 18 are installed inside the screw holes 17. The detachable design of the screws 18 facilitates the installation and replacement of the buffer base 2, and ensures the consistency of the connection strength by controlling the tightening torque, avoiding the increase of wheel-rail clearance due to loose connection, and improving the safety and comfort of high-speed train passage.

[0023] like Figures 1-7 As shown, the buffer base 2 has a positioning groove 15 extending towards the wing rail base 1. A positioning block 16 adapted to the positioning groove 15 is installed on the top side of the connecting base 4. The positioning groove 15 of the buffer base 2 and the positioning block 16 of the connecting base 4 are adapted to achieve precise docking between the buffer base 2 and the connecting base 4, ensuring the accuracy of the connection position and avoiding uneven wheel-rail transition caused by docking deviation. At the same time, this positioning structure can play a guiding role when the connecting base 4 is installed, shortening the installation time of the connecting base 4, improving the assembly efficiency of the frog module, and can also share the lateral load on the connecting base 4, reduce the stress on the fixing mechanism 5, and extend the service life of the fixing mechanism 5.

[0024] like Figures 1-7As shown, the fixing mechanism 5 includes a first fixing plate 501 equidistantly installed on the side of the wing rail base 1. A long plate 502, fixed in the extending direction of the buffer base 2, is provided on the top outer side of the first fixing plate 501. A second fixing plate 503 is equidistantly installed on the side of the long plate 502 near the wing rail base 1, and the first fixing plate 501 and the second fixing plate 503 are fixed together by bolts 504. The fixing mechanism 5, composed of the first fixing plate 501, the long plate 502, the second fixing plate 503, and the bolts 504, is fixed by... The fixed plates 501 and 503 are evenly distributed, so that the fixing force of the long plate 502 on the bearing base 3 is evenly distributed, avoiding deformation of the bearing base 3 due to excessive local stress. The detachable connection of the bolts 504 makes it easy to quickly disassemble the fixing mechanism 5 when the bearing base 3 needs to be replaced, reducing maintenance time. At the same time, the bolt connection has high reliability, which can ensure that the long plate 502 does not loosen under the impact load of long-term high-speed train operation, ensuring the stable operation of the bearing base 3 and reducing the risk of train operation safety.

[0025] Working principle: During the module assembly stage, the buffer base 2 is first positioned and connected to the wing rail base 1 through the splicing assembly. The groove 6 on the parallel end of the concave side of the wing rail base 1 provides the installation reference for the splicing assembly. The limiting plate 9 at the end of the buffer base 2 away from the bearing base 3 is embedded in the groove 6. The toothed grooves 10 on both sides of the limiting plate 9 mesh with the toothed plate 11. An elastic adjustment structure is formed by the toothed plate 11, which is fixed at only two ends. At the same time, the groove 7 at the inclined end of the wing rail base 1 cooperates with the limiting block 8 of the buffer base 2 to complete the dual positioning of the buffer base 2 from both parallel and inclined directions. Then, the screw hole 17 through the end of the wing rail base 1 to the limiting plate 9 and the screw 18 are locked to ensure that the buffer base 2 and the wing rail base 1 are not loosely connected. The detachable design of the screw 18 provides operating space for subsequent maintenance. Next, the two sets of buffer bases 2 face each other and support the bearing base 3 on one side. The connecting base 4 installed on the other side of the wing rail base 1 is precisely connected to the positioning groove 15 of the buffer base 2 through the positioning block 16 on its top. This not only realizes the rapid guidance and installation of the connecting base 4, but also shares the lateral load on the connecting base 4. The stability of the bearing base 3 is further enhanced by the fixing mechanism 5. The fixing plate 1 501 on the side of the wing rail base 1 is aligned with the fixing plate 2 503 on the long plate 502. After the bolts 504 are tightened, the long plate 502 evenly wraps around the bearing base 3 to avoid local deformation of the bearing base 3. During the train operation phase, when the high-speed train wheelset passes through the frog, the load-bearing base 3 directly bears the wheel-rail impact load. The buffer base 2 absorbs part of the impact energy by utilizing its own structural characteristics. At the same time, the intermediate elastic toothed plate 11 in the splicing assembly further buffers the load through slight deformation, reducing stress concentration and damage to the limiting plate 9 and toothed plate 11. The positioning and matching of the connecting base 4 and the buffer base 2, as well as the uniform fastening effect of the fixing mechanism 5, ensure that the load-bearing base 3 always maintains a stable position, avoiding displacement that could lead to uneven wheel-rail transition. The toothed plate 11 and the mounting plate 13 form a force transmission system through the connecting block 12. The snap-fit ​​block 14 strengthens the structural rigidity of the mounting plate 13, enabling the splicing assembly to bear and distribute the load as a whole, ensuring the connection strength of each module, achieving smooth wheel-rail contact, and reducing impact noise and wear. When vulnerable components such as the buffer base 2 and the load-bearing base 3 are worn or damaged, it is not necessary to disassemble the entire frog. Simply unscrew the bolts 504 of the fixing mechanism 5, remove the long plate 502, and remove the screws 18 at the end of the wing rail base 1. The buffer base 2 or the load-bearing base 3 can then be separated for replacement. The new module is quickly reset through the positioning structure and splicing components, and then locked by the screws 18 and bolts 504 to complete the maintenance work, which greatly shortens the downtime and reduces the operation and maintenance costs.
