Description

Technical Field

[0001] The invention relates to the technical field of floating slab roadbeds, and in particular to a novel floating slab roadbed vibration damper. Background Art

[0002] The floating slab roadbed is a type of roadbed structure used in rail transit, and is usually used to reduce the vibration and noise impact of trains on the track structure and the surrounding environment. The shock absorber is installed between the floating slab and the foundation, and attenuates the vibration energy generated by the train passing through elastic or damping elements, reducing the vibration transmitted to the surrounding soil and buildings through the roadbed structure. The reduction of vibration also helps to reduce the noise level. By reducing vibration and noise, the floating slab roadbed can provide a smoother and more comfortable riding experience, reducing passengers' discomfort with vibration and noise.

[0003] After searching, the invention patent with publication number CN113983113B discloses a new type of floating plate roadbed shock absorber, including a piston assembly and a cylinder; the piston assembly includes a piston rod, the first end of the piston rod extends into the cylinder, the second end extends out of the cylinder, and the piston rod can move along the axial direction of the cylinder; the cylinder is filled with oil; the cylinder is connected to the foundation, and the second end of the piston rod is connected to the floating plate roadbed. The shock absorption performance is improved when the vehicle passes, and the stiffness of the shock absorber is improved when the vehicle does not pass, so as to ensure the support effect on the floating plate roadbed.

[0004] Although the above patent has certain beneficial effects, it utilizes the oil passage to exchange oil between the lower cavity and the upper cavity to consume energy and achieve the vibration reduction effect. The oil passage requires reliable sealing, which places high requirements on the quality and installation of the seals. If there is a problem with the sealing, oil leakage will occur, the vibration reduction effect will be weakened or even the shock absorber will be damaged. At the same time, the performance of the oil is easily affected by temperature, which in turn affects the working characteristics of the shock absorber. Therefore, the vibration reduction effect is not good when using simple oil exchange for vibration reduction, which affects the stability of the floating plate roadbed and makes the overall practicality of the shock absorber poor. Summary of the invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The bottom of the upper cover plate is connected to a U-shaped permanent magnet through a connecting assembly, the opening of the U-shaped permanent magnet is downward, an electromagnet is fixedly installed at the bottom of the inner wall of the cylinder, the electromagnet corresponds to the U-shaped permanent magnet and has the same magnetic properties, and an adjustment assembly is arranged inside the cylinder, the adjustment assembly is used to control the repulsive force of the electromagnet on the U-shaped permanent magnet;

[0009] A plurality of damping rods are fixedly connected to the bottom of the U-shaped permanent magnet, and the plurality of damping rods are evenly distributed at the bottom of the U-shaped permanent magnet. The outer walls of the plurality of damping rods are respectively provided with conical spiral blades, and the outer diameter of the conical spiral blades gradually decreases from top to bottom, and the pitch gradually increases.

[0010] Preferably, the sealing assembly comprises two throat hoops, the two throat hoops are arranged on the outer wall of the telescopic sleeve, and the two throat hoops are respectively used to seal the connection between the telescopic sleeve and the upper cover plate and the cylinder.

[0011] Preferably, the buffer assembly comprises a spring fixedly mounted on the bottom of the inner wall of the cylinder, and the top of the spring is in contact with the upper cover plate.

[0012] Preferably, the connecting assembly comprises a connecting rod fixedly mounted on the bottom of the upper cover plate, and the bottom of the connecting rod is fixedly connected to the top of the U-shaped permanent magnet.

[0013] Preferably, a plurality of coils are fixedly mounted on the bottom of the inner wall of the cylinder, the heights of the plurality of coils gradually decrease along the same direction, and the plurality of coils are equidistantly distributed on the bottom of the inner wall of the cylinder, and the plurality of coils are used to cut the magnetic flux lines generated by the U-shaped permanent magnet.

[0017] Preferably, the regulating component comprises an electromagnet circuit, the electromagnet circuit is fixedly connected to the electromagnet, and one end of the electromagnet circuit away from the electromagnet is fixedly connected to the energy storage device and has an adjustable power supply.

[0018] Preferably, a current transformer 1 is fixedly mounted on the coil integration circuit.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] The present invention installs devices such as a telescopic sleeve, a U-shaped permanent magnet and an electromagnet. After the electromagnet is energized, a repulsive force is generated on the U-shaped permanent magnet. The repulsive force serves as an additional vibration reduction mechanism to further reduce the vibration of the upper cover plate. The magnetic field strength is changed by adjusting the current intensity, thereby adjusting the magnitude of the repulsive force, thereby achieving precise control of the vibration reduction effect, and further controlling the heights of the upper covers of multiple vibration absorbers to be relatively consistent, which helps to avoid uneven settlement or deformation of the track bed and maintain the flatness and stability of the track.

[0021] The present invention installs devices such as a damping rod, a connecting rod and a spring, and the outer wall of the damping rod is provided with a conical spiral blade. The outer diameter of the spiral blade gradually decreases from top to bottom, and the pitch gradually increases from top to bottom. During the vibration process, the more the damping rod moves downward, the contact area between the threaded blade and the damping agent increases accordingly. According to the principle of damping, the damping force is proportional to the contact area, which enhances the interaction between the threaded blade and the damping agent, improves the absorption and dispersion efficiency of the vibration energy, helps to better suppress the vibration, enables the shock absorber to adapt to the changes in the vibration frequency and amplitude, and provides a more stable vibration reduction effect.

[0022] The present invention installs a plurality of coils at the bottom of the inner wall of the cylinder. When the U-shaped permanent magnet falls with the vibration of the upper cover plate, the coil cuts the magnetic flux line to generate current. The interaction between the coil and the U-shaped permanent magnet further increases the damping of the system. The force generated by electromagnetic induction generates a reaction force on the U-shaped permanent magnet to offset a part of the vibration energy, thereby enhancing the vibration reduction effect. At the same time, the heights of the plurality of coils are gradually reduced in the same direction and are equidistantly distributed. Each coil generates a different induced current according to the relative position with the U-shaped permanent magnet. The position of the U-shaped permanent magnet is determined by the current transformer 2 arranged between each coil and the coil integration circuit, and the internal vibration reduction condition of the vibration absorber is analyzed, thereby ensuring the normal operation of the vibration absorber and ensuring the running stability of the equipment.

[0023] The present invention installs a coil integration circuit, a storage device and a current transformer. When the coil cuts the magnetic flux lines, the mechanical energy of vibration is converted into electrical energy. The storage device stores the electrical energy and supplies power to the current transformer 1, the current transformer 2 and the adjustable power supply, so as to realize energy recovery and reuse and improve energy utilization efficiency. After the current transformer 1 senses the abnormal current in the coil integration circuit, it immediately feeds back a signal to the maintenance personnel. The maintenance personnel repair the corresponding shock absorber through the feedback, without the need to carry out complicated disassembly and inspection of the entire system or equipment, and only need to focus on the shock absorber with problems, thereby improving the maintenance efficiency and enhancing the practicality of the equipment.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figures 1 to 6A novel floating plate track bed vibration absorber comprises a plurality of vibration absorbers 1 and a battery accumulator 3. The vibration absorber 1 comprises an upper cover plate 11, a throat hoop 12, a telescopic sleeve 13 and a cylinder 14. The upper cover plate 11 is located above the cylinder 14. The telescopic sleeve 13 is located between the upper cover plate 11 and the cylinder 14 and is positioned and installed together with the upper cover plate 11 and the cylinder 14 through an installation groove. After the installation of the telescopic sleeve 13 is completed, the joint is sealed with a sealant. There are two installation grooves, which are respectively located on the outer walls of the upper cover plate 11 and the cylinder 14. There are two throat hoops 12. The two throat hoops 12 are sleeved on the outer wall of the telescopic sleeve 13 and correspond to the two installation grooves respectively, so that the connection between the telescopic sleeve 13 and the upper cover plate 11 and the cylinder 14 is more firmly connected, the sealing inside the vibration absorber 1 is enhanced, and it is helpful to maintain the stability and integrity of the internal structure of the vibration absorber 1, better isolate external vibration and impact, reduce energy loss, thereby improving Vibration reduction effect, the telescopic sleeve 13 connects the upper cover 11 and the lower cylinder 14, allowing the two to move relative to each other within a certain range while maintaining a stable connection, which helps to maintain the integrity of the structure. The bottom of the inner wall of the cylinder 14 is fixedly connected with a spring 18, and the top of the spring 18 is in contact with the upper cover 11. The main function of the spring 18 is to buffer and adjust the impact force generated by the vibration of the upper cover 11. When the upper cover 11 is vibrated, the spring 18 can absorb and buffer these vibrations, and reduce the amplitude and frequency of the vibration through its elastic deformation. The interior of the cylinder 14 is filled with a damper 112, which is also called damping grease. It has excellent vibration reduction, shock absorption, blocking and buffering properties. The damper 112 is a material that can absorb and disperse energy, which can further reduce the impact of vibration on the system. When vibration occurs, the damper 112 can consume vibration energy through its viscosity or friction properties.

[0033] A connecting rod 19 is fixedly installed at the bottom of the upper cover 11, and a U-shaped permanent magnet 111 is fixedly installed at the bottom of the connecting rod 19. The opening of the U-shaped permanent magnet 111 is downward, and an electromagnet 114 is fixedly installed at the bottom of the inner wall of the cylinder 14. The electromagnet 114 is fixedly connected to the electromagnet circuit 16. The electromagnet 114 has the same magnetic properties as the U-shaped permanent magnet 111 and repel each other. The repulsive force serves as an additional vibration reduction mechanism to further reduce the vibration of the upper cover 11. When vibration occurs, the electromagnet 114 changes its magnetic field strength by adjusting the current intensity, thereby adjusting the size of the repulsive force to achieve precise control of the vibration reduction effect, thereby controlling the height of the upper cover 11 of multiple shock absorbers 1 to be relatively consistent, which helps to avoid uneven settlement or deformation of the track bed and maintain the flatness and stability of the track.

[0034] A plurality of damping rods 110 are fixedly installed at the bottom of the U-shaped permanent magnet 111, and the plurality of damping rods 110 are evenly distributed at the bottom of the U-shaped permanent magnet 111. A conical spiral blade is fixedly installed on the outer wall of the damping rod 110, and the outer diameter of the spiral blade gradually decreases from top to bottom, and the pitch gradually increases from top to bottom. During the vibration process, the more the damping rod 110 moves downward, the deeper the threaded blade penetrates into the damping agent 112, and as the depth increases, the contact area with the damping agent 112 also increases accordingly. According to the principle of damping, the damping force is proportional to the contact area, so that the damping force in the shock absorber 1 gradually increases, thereby better suppressing vibration, allowing the shock absorber 1 to adapt to changes in vibration frequency and amplitude, and providing a more stable vibration reduction effect, thereby effectively reducing the impact of vibration and impact on the system, and at the same time helping the damping agent to provide a more uniform resistance distribution under different vibration conditions, avoiding local resonance or uncoordinated vibration response in the system.

[0035] A plurality of coils 113 are fixedly installed at the bottom of the inner wall of the cylinder 14. The heights of the plurality of coils 113 gradually decrease in the same direction and are equidistantly distributed at the bottom of the inner wall of the cylinder 14. The plurality of coils 113 correspond to the U-shaped permanent magnets 111. When the U-shaped permanent magnets 111 drop as the upper cover plate 11 vibrates, they pass through the plurality of coils 113. Since the magnetic field generated by the U-shaped permanent magnets 111 intersects with the coils 113, the coils 113 cut the magnetic flux lines. According to Faraday's law of electromagnetic induction, an induced electromotive force is generated in the coils 113, and then an electric current is generated, converting the mechanical energy of the vibration into electrical energy, thereby realizing energy conversion and recovery. Through the interaction between the coils 113 and the U-shaped permanent magnets 111, the damping of the system is further increased. When the U-shaped permanent magnets pass through the coils 1 13, the force generated by electromagnetic induction will generate a reaction force on the U-shaped permanent magnet 111, and this force will offset a part of the vibration energy, thereby enhancing the vibration reduction effect. The heights of the multiple coils 113 gradually decrease in the same direction and are equidistantly distributed. When the U-shaped permanent magnet 111 descends, it passes through these coils 113 in turn. Each coil 113 will generate different induced currents according to the different relative positions with the U-shaped permanent magnet 111, thereby realizing precise control of the magnetic force, ensuring the continuity and smoothness of the magnetic force change, and helping to more finely adjust the damping force of the shock absorber. Since the distance between the coils 113 is constant, the magnetic field changes generated are also more uniform and stable, which helps to reduce the influence of magnetic field fluctuations on the vibration reduction effect and improve the stability of the entire system.

[0036] A plurality of coils 113 are connected to a coil integration circuit 17, and current transformers 115 are provided at the connection points. When the coil 113 cuts the magnetic flux lines to generate current, the current transformer 115 senses it and feeds back to the control assembly external to the shock absorber 1. The height of the coil 113 that cuts the magnetic flux lines generated by the U-shaped permanent magnet 111 is determined based on the feedback of the current transformer 115, so as to judge the position of the U-shaped permanent magnet 111 and accurately understand the working state and effect inside the shock absorber 1. Once it is found that the vibration reduction performance has declined, the parameters can be adjusted or components can be replaced in time to ensure the smooth operation of the equipment. The coil integration circuit 17 of the plurality of shock absorbers 1 is fixedly connected to the storage battery 3, and the outer wall of the coil integration circuit 17 is provided with a current transformer 15. When the current in the coil integration circuit 17 is abnormal, the electric After sensing, the current transformer 15 immediately feeds back a signal to the maintenance personnel, who repair the corresponding shock absorber 1 through the feedback. The maintenance personnel do not need to carry out complicated disassembly and inspection of the entire system or equipment, but only need to focus on the problematic shock absorber 1, thereby quickly completing the maintenance task, improving maintenance efficiency, and reducing the work intensity of the maintenance personnel. An adjustable power supply 2 is fixedly connected between the storage device 3 and the electromagnet circuit 16. The adjustable power supply 2 is used to control the current of the electromagnet circuit 16, and then control the current intensity inside the electromagnet 114. The storage device 3 stores electrical energy and supplies power to the corresponding current transformer 15, current transformer 2 115, adjustable power supply 2 and other small-power electrical components along the floating plate track, so as to realize energy recovery and reuse, improve energy utilization efficiency and reduce energy waste.

[0037] In the present invention, the floating plate ballast is installed on the upper cover plate 11, and the floating plate ballast is buffered by numerous shock absorbers 1, which absorb vibrations and protect the foundation while ensuring the smooth operation of rail transit on the floating plate ballast. The telescopic sleeve 13 is positioned and installed with the upper cover plate 11 and the cylinder 14 through the installation groove. After the installation is completed, it is sealed with a sealant and fastened with a throat clamp 12. The spring 18 is installed in the cylinder 14, and the top is in contact with the bottom of the upper cover plate 11. The spring 18 provides elastic support for the shock absorber 1. The bottom of the upper cover plate 11 is welded with a connecting rod 19 and a damping rod 110. The electromagnet 11 at the bottom of the cylinder 14 4 cooperates with the damping agent 112 to provide damping force for the shock absorber 1. The damping rod 110 is symmetrically distributed relative to the U-shaped permanent magnet 111. A spiral blade is provided at the bottom of the damping rod 110. The spiral blade is a conical spiral blade with a smaller outer diameter at the bottom and a larger outer diameter at the top. The pitch of the spiral blade decreases as it moves upward, so that the contact area between the damping rod 110 and the damping agent 112 increases as the damping rod 110 moves downward, so that the damping force on the damping rod 110 gradually increases. In addition, the conical spiral blade facilitates the flow of the damping agent 112, avoiding vibration caused by the obstruction of the flow of the damping agent 112, and finally ensuring that the upper cover plate 11 descends at a uniform speed.

[0038] As the upper cover plate 11 in the shock absorber 1 reciprocates vertically, the connecting rod 19 is also moved with it. A U-shaped permanent magnet 111 is welded at the bottom of the connecting rod 19. As the U-shaped permanent magnet 111 moves vertically, while the damping agent 112 and the electromagnet 114 jointly provide the damping force to the U-shaped permanent magnet 111, the magnetic flux lines generated by the U-shaped permanent magnet 111 are also continuously cut by the coil 113. Several coils 113 are evenly distributed at the bottom of the cylinder 14 and are equidistantly reduced in height in one direction. The magnetic flux lines are cut by each coil 113, thereby generating an electric current in the coil 113. The current flows into the coil integration circuit 17. A current transformer 115 is provided at the junction of each coil 113 and the coil integration circuit 17. When the coil 113 generates a current of a certain intensity, the current transformer 115 will sense it and feedback the control assembly. The feedback control assembly of each current transformer 115 determines whether the movement of the U-shaped permanent magnet 111 reaches the lowest position. The corresponding number of shock absorbers 1 is a group. The coil integration circuit 17 of each group integrates the electric energy and is connected to the storage device 3 of each group. The storage device 3 stores the electric energy and supplies power to each The control assembly includes the current transformer 15, the current transformer 2 115 and the adjustable power supply 2 and other small power electrical components along the floating plate track. The control assembly determines the working state and stress condition of each shock absorber 1 through the feedback of each current transformer 2 115 and makes feedback. The electromagnet 114 at the bottom of the cylinder 14 of each shock absorber 1 is powered by the corresponding adjustable power supply 2. The end of the electromagnet 114 facing the U-shaped permanent magnet 111 has the same pole as the U-shaped permanent magnet 111 to maintain mutual repulsion. The adjustable power supply 2 adjusts the output current accordingly according to the feedback of the control assembly to Changing the magnetic force of the electromagnet 114 also changes the repulsive force on the U-shaped permanent magnet 111, so that the damping force in the shock absorber 1 is adjusted accordingly, ensuring that the heights of the upper covers 11 of each shock absorber 1 are relatively consistent during operation, so that the floating plate track bed rail transit runs smoothly and reduces bumps. The current transformer 15 is installed in the coil integration circuit 17. When the current in the coil integration circuit 17 is abnormal, a signal is immediately fed back to the maintenance personnel. The maintenance personnel can accurately locate the problematic shock absorber 1 through feedback for inspection and maintenance, thereby reducing the work intensity of the maintenance personnel.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
