Description

Technical Field

[0001] The present invention relates to the field of rail transit applications, and in particular, to a subway vibration reduction track structure and a vibration absorber device. Background Art

[0002] The subway is an inevitable means of urban transportation in the process of urban modernization. It has the advantages of large transportation capacity, high speed, safety and reliability, and accurate time, and has become a feasible measure to solve urban traffic congestion, noise and air pollution. On the other hand, the vibration generated by the subway has become a problem that is generally taken seriously by countries around the world. The vibration and noise generated during the operation of subway trains all come from the vibrations of different frequencies in the wheel-rail system. Part of these vibrations is diffused in the form of noise through the reflection of air or surrounding structures. According to the vibration reduction form, it can be divided into two forms: buffer vibration reduction and isolation vibration reduction. Buffer vibration reduction usually only uses elastic bodies for the superstructure of the track, such as rails, fasteners and sleepers, to buffer and attenuate the vibrations transmitted by the running of the vehicle. Isolation vibration reduction usually uses an elastic body to integrally isolate the track bed from the structural foundation to reduce the vibrations transmitted by the running of the vehicle.

[0003] The common subway vibration reduction track structure usually consists of a trapezoidal sleeper track, including a trapezoidal sleeper track composed of trapezoidal sleepers, a track bed, fasteners, etc. The trapezoidal sleeper has a large lateral stiffness and good vibration reduction performance. It is connected to the track through the track bed and fasteners. When the train runs, the interaction between the wheels and the track will generate vibrations. The trapezoidal sleeper track absorbs and isolates the vibrations through the large lateral stiffness and good vibration reduction performance of the trapezoidal sleepers, so that the vibration energy will not be directly transmitted to the track bed and fasteners, thereby reducing the impact on the surrounding environment.

[0004] However, due to the lack of effective vibration reduction measures between the track and the track slab, the track vibration is easily directly transmitted to the track slab, resulting in relatively large noise, affecting the subway surrounding environment, and the overall vibration reduction and noise reduction quality of the track is poor. In addition, the traditional vibration absorber device has limited absorption capacity for different types of vibrations (such as vibrations of different frequencies and amplitudes), and cannot comprehensively and effectively cope with the complex vibration conditions during subway operation, so it cannot well achieve the purpose of vibration absorption and noise reduction and cannot meet the working requirements of rail transit applications. Therefore, a subway vibration reduction track structure and a vibration absorber device are proposed. Summary of the Invention

[0005] The present invention provides the following technical solutions: A subway vibration reduction track structure, comprising: A tunnel foundation, on the top of which convex platforms are installed on both the left and right sides. Track slabs are laid on the tops of the convex platforms, and sleepers are laid on the upper surfaces of the track slabs; Tracks, laid on both the left and right sides on the top of the sleepers, and mounting blocks are clamped on both the left and right sides of the bottoms of the tracks; Slots are provided inside the track slab at positions between the sleepers. Threaded holes are provided at positions outside the slots inside the track slab. Lower rubber vibration isolation plates are laid on the tops of the bosses, and upper rubber vibration isolation plates are laid on both the left and right sides of the bottom of the track slab.

[0006] The present invention provides a vibration absorber device, including: Pouring holes are provided inside the tunnel foundation. A base is inserted inside the pouring holes. Lower corner brackets are connected to the four corners of the top of the base. A base platform is installed at the middle position of the top of the base. First transmission arms are hinged to the inner sides of the lower corner brackets through bearings. Mounting plates are connected to the bottoms of the assembly plates. An extrusion head is installed in the middle of the lower surface of the mounting plate. Upper corner brackets are connected to the four corners of the bottom of the assembly plate. Second transmission arms are installed on the inner sides of the upper corner brackets through bearings. Blocks are installed on the inner sides of the second transmission arms through bearings. An assembly frame is sleeved outside the blocks. A rubber energy release block is inserted in the middle position inside the assembly frame.

[0007] Preferably, installation cavities are provided at corresponding positions inside the bosses and the lower and upper rubber vibration isolation plates. The number of the installation cavities is 4 - 8 groups. Dampers are installed at the bottoms of the inner cavities of the installation cavities.

[0008] Preferably, springs are sleeved outside the dampers. The top ends of the dampers penetrate through the corresponding positions inside the lower and upper rubber vibration isolation plates, and the top ends of the dampers are connected to the corresponding positions at the bottom of the track slab.

[0009] Preferably, assembly plates are inserted inside the slots. Bolts are inserted horizontally on the upper sides inside the assembly plates. Bolts are screwed on both sides inside the bolts, and the bottoms of the bolts are screwed to the corresponding positions inside the track slab.

[0010] Preferably, the upper and lower ends of the rubber energy release block are respectively connected to the inner ends of the extrusion head and the base platform. The first and second transmission arms are sleeved outside the assembly frame.

[0011] Preferably, the height of the base is greater than the depth of the pouring hole. Concrete is poured inside the pouring hole. The bottoms of the inner cavities of the pouring holes are flat.

[0012] Preferably, hinge shafts are installed on the inner sides of the first and second transmission arms. The first and second transmission arms are solid structures. Anti - corrosion coatings are applied to the outsides of the first and second transmission arms.

[0013] Preferably, the thickness of the rubber energy release block is the same as that of the extrusion head and the base, and the outer corners of the extrusion head and the base are rounded.

[0014] Preferably, the assembly frames are all of frame structures, and inward convex corners are provided at the positions of the four corners on the upper and lower sides of the rubber energy release block inside the assembly frames.

[0015] In summary, compared with the prior art, the present invention provides a subway vibration reduction track structure and a vibration absorber device, having the following beneficial effects: 1. By adding the sleeper, the lower rubber isolation plate and the upper rubber isolation plate, the vibration between the track and the track slab can be slowed down, so as to achieve the effect of vibration absorption and noise reduction, so that when the track vibrates, the generated vibration is transmitted to the track slab, and then the track slab absorbs vibration and reduces noise, improving the quality of track noise reduction and vibration reduction; 2. By adding the mounting plate and the extrusion head, when the track slab vibrates, the rubber energy release block can be pressed down by the extrusion head, and the movement of the clamping block can be driven by the first transmission arm and the second transmission arm. The extrusion deformation of the rubber energy release block and the movement of the clamping block can play a role at the same time, effectively absorbing different types of vibrations, thereby improving the overall vibration reduction and noise reduction ability. And when the track slab vibrates, the rubber energy release block is directly pressed down by the extrusion block, converting the vibration energy into the elastic deformation energy of the rubber. At the same time, the first transmission arm and the second transmission arm drive the movement of the clamping block, which also consumes the vibration energy. This direct energy conversion method has high efficiency, can quickly reduce the vibration amplitude, and then reduce the generation of noise. And by transmitting the vibration of the track slab through the extrusion head, the first transmission arm and the second transmission arm, the force is distributed to the rubber block and the clamping block structure, avoiding a single structure from bearing too much impact force, reducing the stress burden of each component. At the same time, since the mounting plate is directly connected to the track slab, it can sense the vibration of the track slab in real time. No matter the vibration amplitude and frequency of the track slab are large or small, it can quickly respond, improving the adaptability of the vibration absorber device.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a technical solution, a subway vibration reduction track structure and a vibration absorber device, including a tunnel foundation 1, a boss 2, a track slab 3, a sleeper 4, a track 5, a mounting block 6, a slot 7, a threaded hole 8, a casting hole 9, a base 10, a lower rubber vibration isolation plate 11, a lower angle code 12, a base platform 13, a first transmission arm 14, a second transmission arm 141, an assembly plate 15, a mounting plate 16, an extrusion head 17, an upper angle code 18, a clamping block 19, an assembly frame 20, a rubber energy release block 21, a plug 22, a bolt 23, an upper rubber vibration isolation plate 24, an installation cavity 25, a damper 26 and a spring 27: Please refer to Figure 1, A subway vibration reduction track structure. On the top of the left and right sides of the tunnel foundation 1, there are convex platforms 2 installed. On the top of the convex platforms 2, there are track slabs 3 laid. On the upper surface of the track slab 3, there are sleepers 4 laid. The track slab 3 is a large precast concrete slab, whose shape is rectangular, and its length is determined according to the laying section length of the subway track, and the width should meet the requirements of accommodating components such as sleepers 4 and tracks 5. Inside the track slab 3, there is also a steel bar structure. These steel bars are distributed in different layers to form a multi-layer steel bar mesh to enhance the overall strength of the track slab 3. For example, a relatively dense steel bar mesh is respectively arranged near the upper and lower surfaces of the track slab 3, and the spacing of the steel bar mesh in the middle part is relatively large. This kind of steel bar layout can effectively resist the bending stress generated by the track slab 3 under the action of the train load. The surface of the track slab 3 has a certain roughness, which is to increase the friction force with the sleeper 4 to ensure the stability of the sleeper 4 on the track slab 3. At the same time, the edges of the track slab 3 are chamfered to avoid bumping and damage during transportation and installation; The track 5 is laid on the top of the left and right sides of the sleeper 4. On the bottom of the left and right sides of the track 5, there are mounting blocks 6 clamped. The track 5 is a long strip structure made of special steel, and its cross-sectional shape is usually I-shaped or trough-shaped. This shape design is based on mechanical principles and can effectively transfer the pressure to the sleeper 4 when bearing the train load and has good bending resistance. The steel of the track 5 has the characteristics of high strength and high toughness and can resist the wear and impact of the train wheels. On the surface of the track 5, there is a wear-resistant coating, which can be applied through processes such as thermal spraying and can further improve the wear resistance of the track 5 and extend its service life. The length of the track 5 is determined according to the laying requirements. During the laying process, adjacent tracks 5 are connected through special connecting components, which can ensure the continuity of the track 5 and can effectively transfer the load when the train passes. The mounting block 6 is a metal block structure, and its shape is designed according to the shape of the bottom of the track 5, generally rectangular, and there is a special shape design at the part clamped with the track 5, such as the cooperation of protrusions and grooves, to ensure the firmness of the clamping. The material of the mounting block 6 usually adopts high-strength alloy steel, which has relatively high strength and hardness and can bear the load transmitted by the track 5. Inside the mounting block 6, there may be some reinforcing rib structures, and these reinforcing ribs are distributed along the main stress direction of the mounting block 6, which can improve the overall strength of the mounting block 6. For example, several reinforcing ribs are arranged in the long axis direction of the mounting block 6, so that the mounting block 6 will not easily deform when bearing vertical and lateral loads; Please refer to Figure 2 , The slot 7 is opened at the position between the sleepers 4 inside the track slab 3. Threaded holes 8 are opened at the positions outside the slot 7 inside the track slab 3. Please refer to Figure 3 and Figure 4, a lower rubber vibration isolation plate 11 is laid on the top of each boss 2, and an upper rubber vibration isolation plate 24 is laid on the left and right sides of the bottom of the track slab 3. Please refer to Figure 7 , installation cavities 25 are formed at corresponding positions inside the boss 2 and the lower rubber vibration isolation plate 11 and the upper rubber vibration isolation plate 24. The number of the installation cavities 25 is 4-8 groups. Dampers 26 are installed at the bottom of the inner cavities of the installation cavities 25. Springs 27 are sleeved outside the dampers 26. The top ends of the dampers 26 penetrate through the corresponding positions inside the lower rubber vibration isolation plate 11 and the upper rubber vibration isolation plate 24, and the top ends of the dampers 26 are connected to the corresponding positions at the bottom of the track slab 3. Please refer to Figure 8 , an assembly plate 15 is inserted into the inside of each slot 7. A bolt 22 is horizontally inserted into the upper side of the inside of the assembly plate 15. Bolts 23 are screwed on both sides of the inside of the bolt 22, and the bottoms of the bolts 23 are screwed to the corresponding positions inside the track slab 3.

[0027] Please refer to Figure 3 , an absorber device of the present invention includes; , a pouring hole 9 is formed in the tunnel foundation 1, and a base 10 is inserted into the inside of the pouring hole 9. Please refer to Figure 5 and Figure 6 , lower corner codes 12 are connected to the four corners of the top of the base 10; , a base platform 13 is installed at the middle position of the top of the base 10. First transmission arms 14 are hinged to the inner sides of the lower corner codes 12 through bearings. Installation plates 16 are connected to the bottoms of the assembly plates 15. An extrusion head 17 is installed at the middle of the lower surface of the installation plate 16. Upper corner codes 18 are connected to the four corners of the bottom of the assembly plate 15; The second transmission arm 141 is mounted on the inner side of the upper corner bracket 18 through bearings. On the inner sides of the second transmission arms 141, locking blocks 19 are mounted through bearings. An assembly frame 20 is sleeved outside the locking blocks 19. A rubber energy release block 21 is inserted at the middle position inside the assembly frame 20. The upper and lower ends of the rubber energy release block 21 are respectively connected to the inner ends of the extrusion head 17 and the base 13. The rubber energy release block 21 is a high-performance rubber composite material, and its main components include natural rubber and special additives. The natural rubber provides its basic elasticity, while the additives are used to adjust its physical properties. These additives may include reinforcing agents such as carbon black to improve the strength of the rubber; and anti-aging agents to prevent the rubber from aging due to factors such as oxidation and heat during long-term use. The upper and lower ends of the rubber energy release block 21 are connected to the inner ends of the extrusion head 17 and the base 13, forming a stable energy transfer link. When the device is subjected to external vibration or impact, the extrusion head 17 will receive pressure from the assembly plate 15, and this pressure will be transmitted to the rubber energy release block 21. Since the rubber energy release block 21 is connected to the base 13, it will absorb and convert part of the received energy and buffer this energy through its own elastic deformation. If the connection is not tight or stable, energy loss or interruption will occur during the energy transfer process, affecting the vibration damping effect of the entire device. At the same time, the thickness of the rubber energy release block 21 is the same as that of the extrusion head 17 and the base 13. This design is also to ensure that the stress distribution among various components is uniform during the energy transfer process. If the thicknesses are inconsistent, local stress concentration may occur, which is likely to cause damage to the components during long-term use; The first transmission arm 14 and the second transmission arm 141 are both sleeved outside the assembly frame 20. The height of the base 10 is greater than the depth of the casting hole 9. This design of the height of the base 10 being greater than the depth of the casting hole 9 has many advantages. The base 10 plays a role of support and fixation in the whole device. Its height design is based on the force analysis and stability requirements of the whole device. When the base 10 is inserted into the casting hole 9, since its height is greater than the depth of the casting hole 9, a part of the base 10 will be exposed outside the casting hole 9. This exposed part of the base 10 can be better connected or cooperated with other components. Concrete is poured inside the casting hole 9. The bottom of the inner cavity of the casting hole 9 is arranged as a flat surface. The casting hole 9 is a part of the whole structure and provides an installation space for the base 10. The concrete poured inside the casting hole 9 plays a role of fixing the base 10. Before pouring the concrete, the casting hole 9 needs to be cleaned and prepared. It is necessary to ensure that there are no sundries and dust inside the casting hole 9, and the bottom of its inner cavity is arranged as a flat surface. This flat surface setting is beneficial to the uniform distribution and solidification of the concrete. When pouring the concrete, the mix ratio of the concrete needs to be adjusted according to specific engineering requirements. Generally, it includes the ratio of cement, sand, gravel and water. The grade of the cement should be appropriate, and the gradation of the sand and gravel should be reasonable to ensure the strength and fluidity of the concrete. During the pouring process, a vibrating tool should be used to vibrate the concrete to make it dense and avoid the appearance of cavities or honeycomb structures. After the concrete pouring is completed, curing is required. During the curing period, appropriate temperature and humidity should be maintained to ensure the normal development of the strength of the concrete. Hinge shafts are installed on the inner sides of the first transmission arm 14 and the second transmission arm 141. The first transmission arm 14 and the second transmission arm 141 are both solid structures. Anti-corrosion coatings are applied on the outsides of the first transmission arm 14 and the second transmission arm 141. The existence of this coating is to protect the transmission arms from corrosion by the external environment. In an environment such as the subway, there may be corrosive substances such as moisture and salt. The anti-corrosion coating can form a protective film on the surface of the transmission arm to prevent these corrosive substances from directly contacting the metal surface of the transmission arm. This anti-corrosion coating may be a special paint or metal coating, with uniform thickness, comprehensive coverage, and good adhesion, and can effectively protect the transmission arm for a long time. The thickness of the rubber energy release block 21 is the same as the thickness of the extrusion head 17 and the base 13. The outer corners of the extrusion head 17 and the base 13 are arranged as rounded corners. The assembly frame 20 is a frame structure. Inside the assembly frame 20, inward convex corners are installed at the four corners on the upper and lower sides of the rubber energy release block 21. The convex corners can play a certain limiting role on the rubber energy release block 21. When the device is subjected to vibration or impact, the rubber energy release block 21 may undergo a certain degree of displacement. Without the limitation of these convex corners, the rubber energy release block 21 may be displaced excessively, resulting in loosening or detachment of the connection with other components.The existence of the convex angles can ensure that the rubber energy release block 21 moves within a reasonable range, guaranteeing the stability of the entire device. At the same time, the dimensions and shapes of these convex angles are also designed to ensure that while playing a limiting role, they will not impede the normal operation of the rubber energy release block 21. For example, they will not affect the elastic deformation and energy conversion functions of the rubber energy release block 21.

[0028] In this solution, by adding the sleeper 4, the lower rubber vibration isolation plate 11, and the upper rubber vibration isolation plate 24, the vibration between the track 5 and the track slab 3 can be reduced, thereby achieving the effect of vibration absorption and noise reduction. When the track 5 vibrates, the generated vibration is transmitted to the track slab 3, and then the track slab 3 absorbs vibration and reduces noise, improving the quality of noise reduction and vibration damping of the track 5.

[0029] In this solution, by adding the mounting plate 16 and the extrusion head 17, when the track slab 3 vibrates, the extrusion head 17 can press down the rubber energy release block 21, and drive the movement of the latch 19 through the first transmission arm 14 and the second transmission arm 141. The extrusion deformation of the rubber energy release block 21 and the movement of the latch 19 can work simultaneously, effectively absorbing different types of vibrations, thereby improving the overall vibration reduction and noise reduction ability. And when the track slab 3 vibrates, the extrusion head 17 directly presses down the rubber energy release block 21 to convert the vibration energy into the elastic deformation energy of the rubber. At the same time, the first transmission arm 14 and the second transmission arm 141 drive the movement of the latch 19, which also consumes vibration energy. This direct energy conversion method has a high efficiency, can quickly reduce the vibration amplitude, and thus reduce the generation of noise. And through the vibration of the track slab 3, the force is distributed to the rubber energy release block 21 and the structure of the latch 19 through the extrusion head 17, the first transmission arm 14, and the second transmission arm 141, avoiding a single structure from bearing too much impact force, reducing the stress burden on each component. At the same time, since the mounting plate 16 is directly connected to the track slab 3, it can then sense the vibration situation of the track slab 3 in real time. Regardless of the vibration amplitude and frequency of the track slab, it can quickly respond, improving the adaptability of the vibration absorber device.

[0030] This solution can reduce the vibration between the track 5 and the track slab 3 by adding the sleeper 4, the lower rubber vibration isolation plate 11 and the upper rubber vibration isolation plate 24, so as to achieve the effect of vibration absorption and noise reduction. (The sleeper 4 is placed between the track 5 and the track slab 3, and it plays a role in dispersing pressure. When the train runs on the track 5, the weight of the train will exert pressure on the track 5. The sleeper 4 can evenly disperse this pressure to the track slab 3, preventing excessive wear or deformation between the track 5 and the track slab 3 due to excessive local pressure. This uniform pressure dispersion method helps to extend the service life of the track 5 and the track slab 3. The lower rubber vibration isolation plate 11 is located between the track slab 3 and the boss 2, and the upper rubber vibration isolation plate 24 is located on both sides of the bottom of the track slab 3. Both the lower rubber vibration isolation plate 11 and the upper rubber vibration isolation plate 24 have excellent elastic and damping characteristics. When the track 5 vibrates, the vibration will be transmitted to the track slab 3. The lower rubber vibration isolation plate 11 and the upper rubber vibration isolation plate 24 can absorb and isolate part of the vibration energy. The lower rubber vibration isolation plate 11 converts part of the vibration energy into heat energy through its own elastic deformation, thereby reducing the vibration transmitted to the boss 2 and the tunnel foundation 1. The upper rubber vibration isolation plate 24 plays an auxiliary buffering role on both sides of the bottom of the track slab 3, further enhancing the vibration absorption effect. The synergistic effect of these two rubber vibration isolation plates makes the vibration generated when the track 5 vibrates be transmitted to the track slab 3, and then the track slab 3 absorbs vibration and reduces noise, improving the quality of noise reduction and vibration reduction of the track 5; In this solution, through the additional mounting plate 16 and extrusion head 17, when the track slab 3 vibrates, the extrusion head 17 can press down the rubber energy release block 21, and drive the movement of the clamping block 19 through the first transmission arm 14 and the second transmission arm 141. The extrusion deformation of the rubber energy release block 21 and the movement of the clamping block 19 can work simultaneously, effectively absorbing different types of vibrations, thereby improving the overall vibration reduction and noise reduction ability. (The mounting plate 16 is directly connected to the track slab 3. This direct connection method enables the mounting plate 16 to accurately sense the vibration conditions of the track slab 3. Whether the vibration of the track slab 3 is slight or severe, high-frequency or low-frequency, the mounting plate 16 can quickly transmit the vibration information to the extrusion head 17. This ensures the fast response ability of the entire vibration absorber device to vibrations and improves the sensitivity of the device. The extrusion head 17 is tightly connected to the rubber energy release block 21. When the track slab 3 vibrates, the extrusion head 17 directly presses down the rubber energy release block 21, converting the vibration energy into the elastic deformation energy of the rubber. This direct energy conversion method is very efficient because it reduces the intermediate links in the energy transfer process and avoids energy loss. The rubber energy release block 21 has good elasticity and energy storage ability. It can store the received vibration energy in the form of elastic deformation, thereby effectively reducing the vibration amplitude. At the same time, the first transmission arm 14 and the second transmission arm 141 are connected to the clamping block 19. When the track slab 3 vibrates, the first transmission arm 14 and the second transmission arm 141 drive the movement of the clamping block 19, which also consumes vibration energy. The first transmission arm 14 and the second transmission arm 141 are of solid structure and have high strength, capable of stably transmitting force. The clamping block 19 moves under the drive of the transmission arm. This movement method can change the transmission direction and form of the vibration energy, converting a part of the vibration energy into the kinetic energy of the clamping block 19, and then consuming the vibration energy.)
