Description

Technical Field

[0001] The present invention relates to the technical field of engineering vibration isolation, and more particularly to a composite tuned vibration reduction and isolation floating slab track bed system with a monitoring function. Background Art

[0002] With the continuous development of urbanization, the TOD mode (Transit-Oriented Development), that is, the development mode oriented by public transportation, has become the core of urbanization development. Among them, the development of subway transportation is one of the key points of the TOD mode, and this development mode will inevitably drive the large-scale development of the area above the subway and its surrounding facilities. However, once this mode develops to a certain extent, the negative impact brought by subway vibration will become more and more serious, affecting people's normal production and life. Therefore, the demand for vibration control in the TOD mode is gradually increasing, and the requirements for vibration control are also gradually improving.

[0003] At present, the vibration control technology for subways that is more commonly used is mainly the steel spring floating slab track bed vibration isolation technology. This technology has played a certain positive role in the vibration control of subways. However, due to the limitation of the height of the subway tunnel, the height of the floating slab track bed is not suitable to be too high, which in turn limits the height of the steel spring. Therefore, the vertical deformation ability of the steel spring is very limited, which limits the vibration isolation effect of the floating slab track bed. At the same time, the energy dissipation ability of the steel spring itself is also weak.

[0004] In summary, the existing subway vibration control technology has very limited vibration isolation effect and energy dissipation ability, which restricts the application of subway vibration control technology and the further development of subway traffic engineering. Therefore, how to improve the vibration control ability, energy dissipation and vibration reduction ability, and reduce the vertical deformation ability of the floating slab track bed is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a composite tuned vibration reduction and isolation floating slab track bed system with a monitoring function.

The support block is provided with a limit groove, and the other end of the shaft rod is limited in the limit groove and can move along the limit groove;

[0012] The tuned vibration absorption mechanism includes a mass block and a connecting spring. One end of the connecting spring is fixed on the top plate, and the mass block is installed at the other end of the connecting spring.

[0013] Furthermore, when the floating slab track bed is vertically vibrated, the isolation spring compresses to provide an isolation effect, and the mass block and the connecting spring act together to produce a vibration absorption effect, thereby damping the floating slab track bed;

[0014] When the floating slab track bed is steered and vibrated, the shaft rod bears the floating slab track bed in the horizontal direction.

[0015] Furthermore, the floating slab track bed is provided with a first installation groove, and the vibration absorption and isolation integrated module is installed in the first installation groove. Both between the top plate and the floating slab track bed and between the top plate and the foundation are fixedly connected by bolts.

[0016] Furthermore, the floating slab track bed is provided with a second installation groove, and the bi-directional tuned vibration damping module is installed in the second installation groove. The bi-directional tuned vibration damping module includes a mass square block, a horizontal spring and a vertical spring.

At the same time, the infrared receiver in the intelligent monitoring and vibration reduction module cannot receive the signal from the infrared transmitter, and the active frequency modulation device is in the on state. The floating slab track bed is vibration-reduced through the active frequency modulation device, increasing the vibration reduction effect of the floating slab track bed.

[0025] 2. When the present invention further bears the subway vibration load on the basis of bearing the self-weight load of the subway train, the spring vibration isolation mechanism in the vibration absorption and isolation integrated module provides a vibration isolation effect for the floating slab track bed, and the tuned vibration absorption mechanism generates a tuned vibration absorption effect. The two work together to provide the functions of vibration reduction and isolation for the floating slab track bed. The vertical spring in the two-way tuned vibration reduction module further increases the vertical vibration reduction effect of the floating slab track bed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0037] As Figures 1 to 7 shown, a composite tuned vibration damping and isolation floating slab track bed system with a monitoring function according to the present invention includes a floating slab track bed 1, a vibration absorption and isolation integrated module 5, a bidirectional tuned vibration damping module 6, and an intelligent monitoring and vibration damping module 7. The vibration absorption and isolation integrated module 5 is connected to the floating slab track bed 1 and is used to reduce the vibration of the floating slab track bed 1. The bidirectional tuned vibration damping module 6 is connected to the floating slab track bed 1 and is used to perform vibration damping on the floating slab track bed 1 in the vertical and horizontal directions. The intelligent monitoring and vibration damping module 7 is installed on the floating slab track bed 1 and is used to monitor the state of the floating slab track bed 1 and perform vibration damping on it when the floating slab track bed 1 is vibrated. Under the combined action of the vibration absorption and isolation integrated module 5, the bidirectional tuned vibration damping module 6, and the intelligent monitoring and vibration damping module 7, while providing vertical bearing capacity for the floating slab track bed 1, it can also provide vibration damping effects in the vertical and horizontal directions for the floating slab track bed 1, enabling the floating slab track bed 1 to have good vibration control ability, energy dissipation and vibration damping ability, and small vertical deformation, thereby reducing the vibration of the floating slab track bed 1.

[0038] In the present invention, a foundation 4 is laid in the tunnel 3. The floating slab track bed 1 is provided with a first installation groove 11 and a second installation groove 12. The vibration absorption and isolation integrated module 5 is installed in the first installation groove 11, and the floating slab track bed 1 is supported on the foundation 4 through the vibration absorption and isolation integrated module 5. The bidirectional tuned vibration damping module 6 is installed in the second installation groove 12, and a track 2 is laid on the floating slab track bed 1.

[0039] As Figure 2 shown, the vibration absorption and isolation integrated module 5 includes a top plate 51, a bottom plate 52, a spring vibration isolation mechanism, and a tuned vibration absorption mechanism. The spring vibration isolation mechanism is installed between the top plate 51 and the bottom plate 52 and is used to perform vibration damping on the floating slab track bed 1. The tuned vibration absorption mechanism is installed on the top plate 51 and is used to perform tuned vibration absorption on the floating slab track bed 1.

[0040] Specifically, the spring vibration isolation mechanism includes a vibration isolation spring 53, a shaft rod 54, and a support block 55. The tuned vibration absorption mechanism includes a mass block 57 and a connecting spring 58. The support block 55 is fixedly installed on the bottom plate 52. One end of the shaft rod 54 is fixed on the top plate 51. The vibration isolation spring 53 is sleeved on the shaft rod 54, and both ends of the vibration isolation spring 53 are respectively connected to the top plate 51 and the support block 55. The support block 55 is provided with a limiting groove 56, and the other end of the shaft rod 54 is limited in the limiting groove 56 and can move along the limiting groove 56. One end of the connecting spring 58 is fixed on the top plate 51, and the mass block 57 is fixedly installed at the other end of the connecting spring 58. The top plate 51 is fixedly connected to the floating slab track bed 1 in the first installation groove 11 through bolts, and the bottom plate 52 is fixedly connected to the foundation 4 through bolts.

[0041] When the floating slab track bed 1 is subjected to the self-weight load of the subway train, the floating slab track bed 1 undergoes vertical vibration displacement. At this time, the vibration isolation spring 53 provides a certain vertical bearing capacity for the floating slab track bed 1, and the vibration isolation spring 53 is compressed. At this time, the shaft rod 54 moves along the limit groove 56 and is limited in the limit groove 56; when the floating slab track bed 1 is further subjected to the vertical vibration load of the subway train, the vibration isolation spring 53 provides a vibration isolation effect for the floating slab track bed 1. At the same time, the mass block 57 and the connecting spring 58 act together to produce a tuned vibration absorption effect. Under the combined action of the spring vibration isolation mechanism and the tuned vibration absorption mechanism, the vibration absorption and isolation integrated module 5 plays a role in reducing vibration and isolating vibration, reducing the vibration of the floating slab track bed 1; when the subway train passes through a curve, the floating slab track bed 1 is subjected to horizontal turning vibration, and the shaft rod 54 exerts a horizontal bearing capacity in the limit groove 56 to carry the floating slab track bed 1 in the horizontal direction and improve the horizontal stability of the floating slab track bed 1.

[0042] As Figure 3 shown, the bidirectional tuned vibration reduction module 6 includes a mass block 61, a horizontal spring 62 and a vertical spring 63. One end of the horizontal spring 62 is fixedly installed on the side of the mass block 61, and the other end of the horizontal spring 62 is fixedly connected to the inner wall of the installation groove two 12 of the floating slab track bed 1. One end of the vertical spring 63 is fixedly installed on the bottom surface of the mass block 61, and the other end of the vertical spring 63 is fixedly connected to the inner wall of the installation groove two 12 of the floating slab track bed 1.

[0043] When the floating slab track bed 1 is subjected to the vertical vibration load of the subway train, the mass block 61 and the vertical spring 63 act together to produce a vertical tuned vibration reduction effect, so that the bidirectional tuned vibration reduction module 6 plays a vertical vibration reduction role on the floating slab track bed 1 for vertical vibration reduction; when the subway train passes through a curve, the floating slab track bed 1 is subjected to horizontal turning vibration, and the mass block 61 and the horizontal spring 62 act together to produce a horizontal tuned vibration reduction effect, reducing the vibration of the floating slab track bed 1 in the horizontal direction and improving the horizontal stability of the floating slab track bed 1.

[0044] As Figure 4 shown, the intelligent monitoring and vibration reduction module 7 includes an infrared transmitter 71, an infrared receiver 72, a liquid frequency modulation device and an active frequency modulation device 74. The infrared receiver 72 is used to receive the signal of the infrared transmitter 71. The liquid frequency modulation device is welded and fixed on the floating slab track bed 1, and the infrared receiver 72 and the active frequency modulation device 74 are welded and fixed on the liquid frequency modulation device.

[0045] Specifically, the liquid frequency modulation device includes a water tank 73, which contains liquid. The water tank 73 can be a transparent water tank, facilitating the observation of the liquid level height inside at any time to determine whether liquid needs to be added. The liquid in the water tank 73 can be water or other liquids with strong fluidity. The active frequency modulation device includes a weight block 75, a slide rail bottom plate 76, a control circuit, and a sensor. The control circuit is connected to an infrared receiver 72. The slide rail bottom plate 76 is fixed to the floating slab track bed 1. The weight block 75 is made of a permanent magnet. Part of the weight block 75 is embedded in the slide rail bottom plate 76 to be connected to the slide rail bottom plate 76. The weight block 75 slides vertically up and down along the slide rail bottom plate 76. The sensor, according to the magnitude and direction of the vibration load received by the floating slab track bed 1, causes the slide rail bottom plate 76 to generate a magnetic driving force of corresponding magnitude and opposite direction through the control circuit, driving the weight block 75 to generate a corresponding vertical displacement and then generating a corresponding inertial force, significantly controlling the vibration effect of the floating slab track bed 1.

[0046] When the subway train has not passed by, at this time, the floating slab track bed 1 is not subjected to vibration. The infrared receiver 72 and the infrared transmitter 71 are in a horizontal state. The infrared receiver 72 receives the signal of the infrared transmitter 71, and the active frequency modulation device 74 is in a closed state, that is, the weight block 75 does not slide, and no frequency modulation and vibration reduction are performed on the floating slab track bed 1.

[0047] As Figure 5 shown, when the floating slab track bed 1 is subjected to the self-weight load of the subway train, the floating slab track bed 1 undergoes a vertical vibration displacement. At this time, the infrared receiver 72, the liquid frequency modulation device, and the active frequency modulation device 74 undergo a vertical displacement along with the floating slab track bed 1. The infrared receiver 72 cannot receive the signal of the infrared transmitter 71, and the active frequency modulation device 74 is in an open state. At this time, the active frequency modulation device 74 can actively generate a frequency modulation and vibration reduction effect according to the magnitude and direction of the vibration.

[0048] Specifically, as Figure 6 shown, when the floating slab track bed 1 is subjected to the vibration load of the subway train and the vibration direction is downward, the active frequency modulation device 74 will actively apply a corresponding upward driving force according to the magnitude of the vibration load to make the weight block 75 in the active frequency modulation device 74 move upward to generate a corresponding inertial force; when the vibration direction is upward, the active frequency modulation device 74 will actively apply a corresponding downward driving force according to the magnitude of the vibration load to make the weight block 75 in the active frequency modulation device 74 move downward to generate a corresponding inertial force, thereby achieving the active provision of frequency modulation and vibration reduction.

[0049] As Figure 7 shown, when the subway train passes through a curve, the floating slab track bed 1 is subjected to a horizontal turning vibration. The liquid frequency modulation device provides a horizontal force in the opposite direction to the floating slab track bed 1, and performs horizontal vibration reduction on the floating slab track bed 1 through the liquid frequency modulation device.

[0050] Specifically, when the floating slab track bed 1 is subjected to a load acting horizontally to the left, the liquid in the liquid frequency modulation device will oscillate to the right due to inertia, generating a reaction force acting horizontally to the right, and then exerting a force on the floating slab track bed 1, significantly reducing the vibration of the floating slab track bed 1; when the floating slab track bed 1 is subjected to a load acting horizontally to the right, the liquid in the liquid frequency modulation device will oscillate to the left due to inertia, generating a reaction force acting horizontally to the left, providing frequency modulation and vibration reduction in the horizontal direction, improving the stability of the floating slab track bed 1 in the horizontal direction. At the same time, the transparent water tank 73 has a relatively thin wall, so the internal liquid can generate a higher-frequency sloshing, that is, the response frequency of this liquid frequency modulation device is relatively high.

[0051] The embodiments of the present invention are not limited thereto. According to the above embodiments of the present invention, using the conventional technical knowledge and customary means in the art, without departing from the above basic technical idea of the present invention and without conflict, the above preferred embodiments can also be modified, replaced or combined in various other forms, and the other embodiments obtained all fall within the scope of the protection of the rights of the present invention.
