[0026] The following will be combined with the attached embodiment of the present utility model Figures 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] (like Figure 1 , Figure 2 (As shown) An anchor plate assembly for the end of a turnout concrete sleeper is composed of a hook bar 1, an inner friction plate 2, an anchor end plate 3, and an anti-slurry cap 4.

[0028] It should be noted that: The design of the hook bar 1 usually takes into account the force requirements under different working conditions and can adapt to various complex railway turnout environments. The inner friction plate 2 is placed between the concrete sleeper 6 and the rail or other structural components, and the friction coefficient is increased by increasing the roughness of the contact surface to prevent relative sliding and ensure the stable operation of the turnout system. During the force application process, the inner friction plate 2 can disperse the stress, reduce the direct impact on the concrete sleeper, and extend the service life. The anchoring end plate 3, as the core part of the anchoring plate assembly, has a strong anchoring ability and can ensure a firm connection between the concrete sleeper and the foundation structure. The main function of the grout-proof cap 4 is to prevent grout leakage during concrete pouring or grouting, ensuring the integrity and stability of the internal structure of the concrete sleeper. The grout-proof cap 4 has good sealing performance, can effectively prevent external moisture and impurities from entering the interior of the concrete sleeper, and extend the service life. By preventing grout leakage and improving the sealing performance, the grout-proof cap 4 can also protect the internal structural components such as the steel bars in the concrete sleeper from corrosion and damage to a certain extent.

[0029] The inner friction plate 2 is vertically and fixedly connected to the anchoring end plate 3. The vertically fixed connection method can ensure a closer and firmer connection between the inner friction plate and the anchoring end plate, thus improving the structural stability of the entire anchoring plate assembly. This stable connection can more effectively resist various forces and vibrations from the track, ensuring the long-term stable operation of the turnout system. The vertically fixed connection design helps to optimize the force transmission path, enabling the forces from the rail or other structural components to be more evenly dispersed into the concrete sleeper, thereby reducing the phenomenon of local stress concentration. This helps to extend the service life of the concrete sleeper and reduce the risk of damage caused by stress concentration. The vertically fixed connection method can reduce the problems of wear and corrosion caused by loose connection. When the inner friction plate and the anchoring end plate are tightly connected, the gap between them is reduced, thus reducing the chance of entry of harmful substances such as moisture and impurities, and helping to extend the service life of the entire anchoring plate assembly.

[0030] The upper surface of the internal friction plate 2 is flush with the upper surface of the switch sleeper 6; when the upper surface of the internal friction plate 2 is flush with the upper surface of the switch sleeper 6, it can ensure that the load from the track can be more evenly distributed on the switch sleeper. This uniform force distribution helps to reduce the stress concentration phenomenon and lower the risk of damage to the switch sleeper due to local overload. The flush design makes the contact area between the internal friction plate and the switch sleeper larger and the connection more stable. This stable connection can enhance the overall stability of the turnout system and ensure that the turnout system can maintain a stable working state when the train passes. The flush design of the internal friction plate 2 and the upper surface of the switch sleeper 6 helps to improve the supporting force of the ballast bed on the switch sleeper. This increase in the supporting force can enhance the lateral stability of the track, reduce the lateral displacement and vibration generated when the train passes, and ensure the safe operation of the train. The flush design makes it more convenient for the maintenance and repair of the switch sleeper. Maintenance personnel can more easily access all parts of the switch sleeper to carry out necessary inspections and repair operations, thereby improving the efficiency and quality of maintenance and repair. Due to the uniform force and stable connection, the wear between the switch sleeper and the internal friction plate will be correspondingly reduced. This reduced wear helps to extend the service life of the switch sleeper and the internal friction plate, and lower the replacement frequency and cost.

[0031] The inner side surface of the internal friction plate 2 is vertically and fixedly connected to the end of the anchoring end plate 3; the anchoring end plate 3 is arranged at the end of the switch sleeper 6 and is closely attached and aligned with the end of the switch sleeper 6; the anchoring end plate 3 is reserved with an anchoring hole 31 and a steel bar hole 32 (combined Figure 3 ); the anchoring hole 31 is used to fix the anchoring end plate 3; the steel bar hole 32 is used to tension the longitudinal steel bars; the internal friction plate 2 is installed with a grout-proof cap 4; the internal friction plate 2 is vertically connected to the hook-shaped steel bars 1; the hook-shaped steel bars 1 are embedded in the concrete to improve the bonding property between the anchoring plate assembly and the concrete. It should be noted that: the inner side surface of the internal friction plate 2 is vertically and fixedly connected to the end of the anchoring end plate 3, this design ensures the connection strength between the two, and prevents loosening or displacement due to uneven force. The anchoring end plate 3 is arranged at the end of the switch sleeper 6 and is closely attached and aligned with the end of the switch sleeper 6, further enhancing the connection stability between the anchoring end plate and the switch sleeper, making the entire anchoring system able to more effectively resist external loads. The reserved steel bar hole 32 on the anchoring end plate 3 is used to tension the longitudinal steel bars, this design enables the longitudinal steel bars to be arranged in a predetermined direction and position, thereby optimizing the stress performance of the entire anchoring system. The hook-shaped steel bars 1 are embedded in the concrete and vertically connected to the internal friction plate 2, which not only improves the bonding property between the anchoring plate assembly and the concrete, but also enhances the crack resistance of the concrete and prevents the anchoring failure caused by the cracking of the concrete. The prefabricated connection holes and threaded holes on the internal friction plate 2 simplify the installation process and improve the construction efficiency. At the same time, the threaded connection also improves the reliability and stability of the connection, which is conducive to the control of construction quality.

[0032] In the above embodiments, as a further improvement of the present utility model: the inner friction plate 2 is perpendicularly welded and fixedly connected to the anchoring end plate 3 as a whole. It should be noted that: through the way of perpendicular welding, the inner friction plate 2 and the anchoring end plate 3 form a rigid connection. This connection method has higher strength and stiffness than non-welded connections (such as bolt connections), and can more effectively resist external loads and vibrations, thereby enhancing the structural stability of the entire anchoring plate assembly. The welded connection can ensure the close fit between the inner friction plate and the anchoring end plate, reduce the risk of connection failure caused by loosening, and ensure the long-term stable operation of the turnout system. The design of perpendicular welding and fixed connection makes the force transmission path clearer and more direct, and can more effectively transfer the load from the track to the anchoring end plate through the inner friction plate, and then further transfer it to the foundation structure, reducing the loss and dispersion of force during the force transmission process. The welded connection can ensure that the stress distribution at the connection part is more uniform, reduce the risk of local damage caused by stress concentration, and improve the bearing capacity and service life of the entire anchoring plate assembly. The welded connection has the advantages of fast construction speed and simple process compared with other connection methods (such as bolt connections), can shorten the construction period, and reduce the construction cost. The quality of the welded connection can be guaranteed through welding process and welding quality inspection, and it is easier to achieve quality control and acceptance compared with other connection methods. Due to the stability and durability of the welded connection, the maintenance workload caused by connection loosening or damage is reduced, and the maintenance cost is lowered.

[0033] In the above embodiments, as a further improvement of the present utility model: the inner friction plate 2 is vertically welded and fixedly connected to the hook rib 1. The vertical welding and fixed connection method forms a rigid connection between the inner friction plate 2 and the hook rib 1. This connection method has high strength and stability, can effectively resist external loads and vibrations, thereby enhancing the structural stability of the entire anchor plate assembly. The welded connection can ensure the tightness and stability of the connection part, reducing the risk of connection failure caused by loosening, which is crucial for ensuring the long-term stable operation of the turnout system. The design of vertical welding and fixed connection makes the force transmission path more direct and efficient, and can more effectively transmit the load from the track through the inner friction plate 2 to the hook rib 1, and then further transmit it to the switch sleeper 6, reducing the loss and dispersion of force during the force transmission process. The welded connection has the advantages of fast construction speed and simple process compared with other connection methods (such as bolt connection). At the construction site, the connection between the inner friction plate 2 and the hook rib 1 can be quickly completed through welding equipment, shortening the construction period and improving the construction efficiency. The quality of the welded connection can be guaranteed through welding technology and welding quality inspection. During the construction process, measures such as controlling welding parameters, selecting appropriate welding materials and welding methods can be taken to ensure the welding quality, thereby improving the reliability and durability of the entire anchor plate assembly. Due to the stability and durability of the welded connection, the maintenance workload caused by connection loosening or damage is reduced, and the maintenance cost is lowered. At the same time, the additional costs generated by replacing damaged components are also reduced, improving the economic benefits.

[0034] In the above embodiments, as a further improvement of the present utility model: the anchor end plate 3 is fixed on the switch sleeper mold template, and the longitudinal steel bars are tensioned through the steel bar holes 32 and then concrete is poured. It should be noted that: the fixation of the anchor end plate 3 ensures the precise positioning of the longitudinal steel bars before pouring, reducing the construction errors caused by steel bar displacement. After the longitudinal steel bars are tensioned through the steel bar holes 32, a stable steel bar skeleton can be formed, providing good support for concrete pouring, which helps to improve the overall stability of the switch sleeper. The longitudinal steel bars can significantly increase the flexural stiffness of the concrete structure, thereby enhancing its flexural bearing capacity and making the switch sleeper more stable and reliable when bearing the train load. The longitudinal steel bars can cause shrinkage deformation and shear deformation of the concrete structure under external forces such as earthquakes, effectively reducing earthquake damage and improving the seismic performance of the switch sleeper. The addition of longitudinal steel bars can reduce the discreteness of the concrete structure, making its overall performance more uniform, which helps to improve the service life of the switch sleeper. This technology simplifies the construction process, reduces the adjustment work during construction, and helps to speed up the construction progress. With the development of the railway towards heavy haul, higher requirements are put forward for the bearing capacity and stability of the switch sleeper. This technology can better meet the operation requirements of heavy haul trains by enhancing the performance of the concrete structure.

[0035] In the above embodiments, as a further improvement of the present invention: (as Figure 4 shown) there are two hook ribs 1, and the two hook ribs 1 are symmetrically arranged on the inner friction plate 2; the two hook ribs 1 are arranged on both sides of the embedded sleeve 5, and the hook ribs 1 and the embedded sleeve 5 do not interfere with each other. It should be noted that: the two hook ribs 1 are symmetrically arranged on the inner friction plate 2, and this layout can ensure the uniform transmission and dispersion of force, avoiding structural deformation or damage caused by uneven force on one side. The firm connection between the hook ribs 1 and the inner friction plate 2, and their being part of the overall structure, enhance the stability of the entire anchoring system, making the entire structure more stable and reliable when bearing external forces. The setting of the two hook ribs 1 enables them to share the load from the track together, reducing the stress burden on a single hook rib and improving the load-bearing capacity of the entire structure. The non-interference design between the hook ribs 1 and the embedded sleeve 5 ensures a clear and efficient force transmission path, avoiding force transmission loss or efficiency reduction caused by mutual interference. During the construction process, due to the reasonable layout and non-interference between the hook ribs 1 and the embedded sleeve 5, it enables the construction personnel to install and position more easily, simplifying the construction process.

[0036] In the above embodiments, as a further improvement of the present invention: (as Figure 5As shown, the hooked bar 1 is formed by bending a deformed bar. The hooked bar 1 is embedded in the concrete and is used to tightly bond with the concrete, thereby providing a gripping force for the entire turnout concrete sleeper. It should be noted that: the surface of the deformed bar has threads, and these threads can increase the contact area with the concrete, thus forming a stronger mechanical biting force after the concrete solidifies. This biting force helps to tightly bond the hooked bar with the concrete, improving the stability and durability of the overall structure. The hooked bar embedded in the concrete will have a chemical reaction and physical bonding with the concrete during the concrete pouring and solidification process, forming an inseparable whole. This tight bonding can effectively prevent the relative sliding and separation between the hooked bar and the concrete, ensuring the stable performance of the turnout sleeper during long-term use. As a reinforcing bar in the concrete structure, the hooked bar can share the load from the track and transfer it to the surrounding concrete. This sharing effect can reduce the stress burden on the concrete and improve its bearing capacity, thereby extending the service life of the turnout sleeper. When the turnout sleeper is subjected to a bending moment, the hooked bar can exert its bending resistance and jointly resist the bending deformation with the concrete. This synergistic effect can significantly improve the bending stiffness and bearing capacity of the turnout sleeper, ensuring its stable shape and performance when the train passes. Using the hooked bar formed by bending a deformed bar for embedded construction can simplify the construction process and reduce the adjustment and calibration work during construction. This simplification not only improves the construction efficiency but also helps to reduce the construction cost. The hooked bar formed by bending a deformed bar can be customized and processed according to specific working conditions and requirements to adapt to turnout sleepers of different sizes, shapes, and requirements. This flexibility makes the hooked bar have a wide application prospect in railway construction. Since the hooked bar is tightly bonded with the concrete, potential problems can be more easily identified and located during the later maintenance process. This convenience helps to reduce the maintenance cost and improve the maintenance efficiency.

[0037] In the above embodiments, as a further improvement of the present utility model: the anchoring plate assembly is closely combined with the concrete and forms an integral body with the switch sleeper 6. It should be noted that after the anchoring plate assembly is closely combined with the concrete and the switch sleeper, an integral stress-bearing structure is formed. This integral structure can more effectively resist external loads and vibrations, ensuring the long-term stable operation of the turnout system. Through the integral combination, the load can be evenly dispersed, reducing the phenomenon of local stress concentration, thereby reducing the risk of structural damage. The close combination among the anchoring plate assembly 2, the concrete and the switch sleeper 6 enables them to work together and jointly bear the load from the track. This synergistic effect can significantly improve the load-bearing capacity of the entire turnout system, ensuring its stability when heavy-haul trains pass through. The integral combination structural design enhances the stiffness of the turnout system, making it not easy to deform when subjected to external forces, thereby improving its stability and durability. The close combination of the anchoring plate assembly and the concrete can reduce the wear caused by relative sliding, thereby extending the service life of the turnout system. The concrete has a certain protective effect on the anchoring plate assembly, reducing the risk of its corrosion and further extending the service life. The close combination of the anchoring plate assembly and the concrete can be achieved during the concrete pouring process without additional fixing steps, thus simplifying the construction process. The integral combination design of the anchoring plate assembly with the concrete and the switch sleeper can adapt to different working conditions and load conditions, and different requirements can be met by adjusting the specifications and layouts of the anchoring plate assembly.

[0038] In the above embodiment, as a further improvement of the utility model: the inner friction plate 2 and the switch sleeper 6 are in the same plane and are tightly combined; the anchoring end plate 3 is located at the end of the switch sleeper 6 and is tightly combined with the switch sleeper 6. It should be noted that the inner friction plate 2 and the switch sleeper 6 are tightly combined in the same plane, so that the entire structure can evenly distribute the load when subjected to force, reducing the possibility of local stress concentration, thereby improving the stability of the structure. The anchoring end plate 3 is located at the end of the switch sleeper 6 and is tightly combined with the switch sleeper, forming a strong anchoring effect, further enhancing the overall connection strength of the turnout structure, and ensuring that it will not loosen or move when the train passes. The tight combination of the inner friction plate 2 and the switch sleeper 6, and the anchoring effect of the anchoring end plate 3, enable the three to work together and jointly bear the load from the track. This collaborative load-bearing mechanism improves the load-bearing capacity of the turnout, ensuring that it can remain stable when a heavy-loaded train passes. The tight combination of the overall structure also increases the rigidity of the turnout, making it less likely to deform when subjected to external forces, thereby improving its load-bearing capacity and stability. The inner friction plate 2 and the switch sleeper 6 are tightly combined in the same plane, reducing the wear caused by relative sliding, thereby extending the service life of the turnout. The tight combination of the anchor end plate 3 and the switch sleeper 6 can also reduce the erosion of the internal structure by the external environment, such as rainwater, salt, etc., further protecting the durability of the turnout. This tightly combined design simplifies the construction process, reduces the steps of installation and adjustment, and improves construction efficiency. The tight combination of the overall structure also makes it easier to identify and locate potential problems during later maintenance, reducing maintenance costs and improving maintenance efficiency. This tightly combined design enables the turnout to adapt to different working conditions and load conditions, and to meet different needs by adjusting the specifications and layout of the inner friction plate 2 and the anchor end plate 3.

[0039] In the above embodiments, as a further improvement of the present utility model: the inner friction plate 2 is prefabricated with connecting holes; the connecting holes are threaded holes, and the anti-slurry cap 4 is screwed to the connecting holes. It should be noted that: the use of threaded design for the connecting holes enables the anti-slurry cap 4 to be easily connected or disassembled with the inner friction plate 2 by rotation. This connection method not only simplifies the installation process but also improves the construction efficiency. When it is necessary to replace or repair the anti-slurry cap 4, the threaded connection allows for quick and convenient disassembly and reinstallation, reducing the maintenance time and cost. The threaded connection can ensure a tight fit between the anti-slurry cap 4 and the inner friction plate 2, effectively preventing the concrete slurry from seeping into the connecting holes during the pouring process, and ensuring the integrity and cleanliness of the structure. Compared with welding or other non-threaded connection methods, the threaded connection shows higher reliability in preventing liquid or gas leakage, especially in high-pressure or high-temperature environments. By adjusting the size and position of the threaded holes, it is possible to adapt to different specifications and models of the anti-slurry cap 4 to meet different engineering requirements. During the installation process, if it is found that the fit between the anti-slurry cap 4 and the inner friction plate 2 is not tight enough or there are other problems, the anti-slurry cap 4 can be rotated for adjustment to ensure the stability and reliability of the connection. The anti-slurry cap 4 can protect the connecting holes from the erosion of concrete slurry and other impurities, thereby extending the service life of the connecting holes. The threaded connection reduces the wear caused by relative sliding, reduces the loss rate of the connecting components, and further extends the service life of the overall structure. The threaded connection is a standardized connection method, which helps to standardize and regularize the construction process, improving the construction quality and efficiency. Compared with traditional welding or other non-standardized connection methods, the threaded connection can reduce the problems caused by construction errors and improve the stability and safety of the overall structure.
