Description

Technical Field

[0001] This utility model relates to the field of floating slab structure technology for rail transit, specifically to an integrated floating slab vibration isolator. Background Technology

[0002] Currently, floating slab tracks are widely used in the rail transit sector. They have the advantage of isolating and reducing the transmission of vibrations and noise generated during train operation to the surrounding environment. In particular, they can reduce the further transmission of vibrations to the underlying foundation structure and the surrounding environment, thus avoiding any impact on the foundation structure and the surrounding environment.

[0003] Common floating slab tracks are equipped with various vibration isolators to isolate and reduce vibration and noise. However, current vibration isolators have relatively limited functionality, their condition cannot be effectively monitored after being put into use, and their installation is also quite complex. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an integrated floating plate vibration isolator, which improves the performance and integrates functions of the vibration isolator through a prefabricated structural design.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An integrated floating plate vibration isolator is characterized by comprising a cover plate, a steel spring, a base, a biomimetic material component, and a fixing member. The base has a cavity, and a first limiting structure is provided at the bottom of the cavity. The steel spring is installed inside the cavity of the base and is laterally limited from its bottom by the first limiting structure. The cover plate is installed on the base and the steel spring, and a second limiting structure is provided on the bottom surface of the cover plate, which laterally limits the steel spring from its top. The biomimetic material component is located at the bottom of the base. The fixing member is used to connect and fix the cover plate and the base to form an integral structure.

[0007] The fastener includes a rubber sealing ring and a hose clamp, wherein the rubber sealing ring is sleeved around the connection between the cover plate and the base and is fixed by the hose clamp.

[0008] Along the height direction of the rubber sealing ring, a plurality of hose clamps are evenly spaced around its periphery.

[0009] The base and the biomimetic material component are respectively provided with limiting grooves for matching the limiting protrusions set on the track bed.

[0010] The advantages of this utility model are: it can track and monitor the working status and vibration reduction effect of the floating slab track in real time during operation; the prefabricated structure makes it easy to install, dismantle and replace, and has a good vibration isolation effect; it is convenient to construct, has high positioning efficiency, and is suitable for promotion.

[0015] Figure 5 This is a schematic diagram of the structure of the rubber sealing ring in this utility model. Detailed Implementation

[0016] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0017] like Figure 1-5 As shown in the figure, numbers 1-5 represent: cover plate 1, steel spring 2, base 3, biomimetic material component 4, rubber sealing ring 5, hose clamp 6, first limiting structure 7, second limiting structure 8, limiting groove 9, and limiting groove 10, respectively.

[0018] Example: Figures 1 to 5 As shown, the integrated floating slab vibration isolator in this embodiment adopts an assembled structure, and when it is installed on the floating slab track, it can play a vibration isolation role.

[0019] Specifically, the vibration isolator in this embodiment includes a cover plate 1, a steel spring 2, a base 3, a biomimetic material component 4, and a fixing component.

[0020] The base 3 has a cavity with a top opening, and the steel spring 2 is installed in this cavity. A first limiting structure 7 is provided at the bottom of the cavity. The first limiting structure 7 is a convex structure that is higher than the bottom surface of the cavity. Its outer contour shape and size match the shape and size of the central hole of the steel spring 2, so as to meet the requirement of being able to be inserted into the central hole of the steel spring 2. During installation, the steel spring 2 is installed inside the cavity of the base 3 and is laterally limited from its bottom by the first limiting structure 7, which ensures that the steel spring 2 will only undergo compression deformation or return to its original position in the vertical direction, and will not undergo unnecessary displacement in the horizontal direction.

[0021] Cover plate 1 is installed on base 3 and steel spring 2. Cover plate 1 is used to encapsulate steel spring 2 and ensure that it can be securely installed inside the cavity of base 3. The bottom surface of cover plate 1 is provided with a second limiting structure 8. The second limiting structure 8 is a convex structure extending downward from the bottom surface of cover plate 1. It can be welded from several components. Its outer contour shape and size are also compatible with the shape and size of the central hole of steel spring 2, satisfying the requirement that it can be inserted into the central hole of steel spring 2. During installation, after steel spring 2 is installed inside the cavity of base 3, it is laterally limited from its top by the second limiting structure 8. Together with the first limiting structure 7, it ensures that steel spring 2 will only undergo compression deformation or return spring in the vertical direction.

[0022] The biomimetic material component 4 is located at the bottom of the base 3. This component 4 is made of flexible piezoelectric fiber composite material, which does not require external power supply and is used to autonomously sense and collect vibration energy when a vehicle passes by. In use, the biomimetic material component 11 is connected to the monitoring system through circuit design, which can track and monitor the working status and vibration reduction effect of the floating slab track in real time during operation.

[0023] The fasteners include a rubber sealing ring 5 and a hose clamp 6, wherein the rubber sealing ring 5 is sleeved around the connection between the cover plate 1 and the base 3 and fixed by the hose clamp 6. In this embodiment, as... Figure 3 As shown, the cover plate 1 and the base 3 each have an inwardly recessed portion. After the cover plate 1 and the base 3 are mated, the rubber sealing ring 5 is fitted onto the inwardly recessed portion, and a hose clamp 6 is then installed around the rubber sealing ring 5 to achieve fixation and sealing. To improve the fixing and sealing effect, as follows... Figure 1 As shown, two hose clamps 6 are evenly spaced around the rubber sealing ring 5 along its height direction.

[0024] like Figure 3 As shown, the base 3 and the bionic material component 4 are respectively provided with limiting grooves 9 and 10 for matching the limiting protrusions set on the track bed; during installation, the bionic material component 4 and the base 3 can be directly placed on the limiting protrusions of the track bed for quick positioning and installation, thereby improving construction efficiency and construction accuracy.

[0025] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
