Description

Technical Field

[0001] This utility model relates to the field of vibration control technology, specifically to a sealing test device for a square vibration isolator. Background Technology

[0002] Currently, steel spring vibration isolators are the primary type used in floating slab track structures for urban rail transit. Steel spring vibration isolators can be categorized into circular and square types based on their shape. In precast steel spring floating slabs, a combination of circular and square vibration isolators offers better economic benefits compared to using circular isolators alone. While sealing solutions for circular vibration isolators are relatively mature, those for square vibration isolators are not yet fully developed. In many rail transit projects, the springs of square vibration isolators remain exposed. To extend the service life of square vibration isolators, a waterproof sealing solution needs to be designed for them. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a square vibration isolator sealing test device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a square vibration isolator sealing test device, comprising a vibration isolator base, a lower frame, an upper frame, a vibration isolator cover plate, and an observation tube; the lower frame is fixedly installed on the upper surface of the vibration isolator base; the upper frame is fixedly installed on the lower surface of the vibration isolator cover plate; the observation tube is welded through and through the middle of the upper surface of the vibration isolator cover plate; one end of the vibration isolator base is aligned with one end of the vibration isolator cover plate; the lower frame is correspondingly arranged with the upper frame.

[0005] Preferably, a sealing test area is provided between the lower frame and the upper frame; the sealing test area is a non-sealed connection area between the lower frame and the upper frame.

[0006] Preferably, a connecting bolt is provided between the vibration isolator base and the vibration isolator cover plate; the connecting bolt is arranged in a triangle and distributed at the front and rear ends of the lower frame and the upper frame.

[0007] Preferably, the width of the sealing test area is determined by the connecting bolt.

[0008] Preferably, the inner wall of the observation tube is coated with an anti-fog layer to ensure clear visibility in high-temperature or humid environments.

[0009] Compared with existing technologies, the advantages of this invention are as follows: This invention ensures the overall stability and sealing of the device through the tight fit of the isolator base, lower frame, upper frame, and isolator cover, thus improving the reliability during experiments. In particular, the sealing test area between the lower and upper frames allows for more precise sealing tests, and the width of the test area is determined by the triangular configuration of the connecting bolts, further improving the structural precision and facilitating detailed analysis of the isolator's sealing performance.

[0010] Secondly, the observation tube provides a direct observation method, allowing for real-time monitoring of the sealing effect and the vibration isolator status during testing, ensuring the visibility of the experiment. Furthermore, the inner wall of the observation tube is coated with an anti-fog layer, a design that ensures researchers maintain a clear view even in high-temperature or humid environments, preventing environmental changes from affecting the observation results and guaranteeing the accuracy of the test results.

[0011] In addition, the triangular arrangement of the connecting bolts enhances the robustness and stability of the device, especially during the sealing test, which can effectively prevent structural loosening caused by external pressure or vibration, thereby improving the durability and long-term stability of the device.

[0014] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0015] A sealing test device for a square vibration isolator includes a vibration isolator base 1, a lower frame 2, an upper frame 3, a vibration isolator cover plate 4, and an observation tube 5. The lower frame 2 is fixedly installed on the upper surface of the vibration isolator base 1. The upper frame 3 is fixedly installed on the lower surface of the vibration isolator cover plate 4. The observation tube 5 is welded through the middle of the upper surface of the vibration isolator cover plate 4. One end of the vibration isolator base 1 is aligned with one end of the vibration isolator cover plate 4. The lower frame 2 and the upper frame 3 are correspondingly arranged.

[0016] The precise fit between the lower frame 2 and the upper frame 3 ensures the effectiveness of the sealing test area 6, making the sealing test more reliable. Furthermore, the observation tube 5 allows for clear observation of the vibration isolator's condition during the experiment, avoiding the problem of limited visibility. In particular, its inner wall is coated with an anti-fog layer 8, ensuring a clear field of view even in high-temperature or humid environments, thereby improving the accuracy of experimental data and the ease of operation for the experimenters. The overall structural design enhances the stability and durability of the device, ensuring high efficiency and reliability during long-term use.

[0017] Preferably, a sealing test area 6 is provided between the lower frame 2 and the upper frame 3; the sealing test area 6 is a non-sealed connection area between the lower frame 2 and the upper frame 3.

[0018] A sealing test area 6 is provided between the lower frame 2 and the upper frame 3. This test area, as a non-sealed connection area, effectively simulates the sealing performance of the vibration isolator in different working environments. This design allows for precise testing of the vibration isolator's performance under non-completely sealed conditions, thus providing a more comprehensive evaluation of its sealing effect and durability. Furthermore, the sealing test area 6 facilitates the detection of potential minor leaks or structural defects in the sealing area, providing important data for subsequent improvements and optimizations, and enhancing the adaptability of the device and the accuracy of experimental data.

[0019] Preferably, a connecting bolt 7 is provided between the vibration isolator base 1 and the vibration isolator cover plate 4; the connecting bolt 7 is triangularly arranged and distributed at the front and rear ends of the lower frame 2 and the upper frame 3.

[0020] By installing connecting bolts 7 between the isolator base 1 and the isolator cover plate 4 in a triangular arrangement, with the bolts distributed at the front and rear ends of the lower frame 2 and the upper frame 3, this design significantly enhances the structural stability and vibration resistance of the device. The triangular arrangement of the connecting bolts evenly distributes external pressure, avoiding localized stress concentration, thereby effectively improving the overall compressive strength and durability of the isolator. Furthermore, the rational bolt layout ensures the tightness and stability of the device during long-term use, reducing loosening or damage caused by vibration or external forces, and improving the reliability and service life of the device.

[0021] Preferably, the width of the sealing test area 6 is determined by the connecting bolt 7.

[0022] By combining the width of the sealing test area 6 with the arrangement of the connecting bolts 7, this design allows for precise control of the size and shape of the sealing area. The arrangement of the connecting bolts 7 directly determines the width of the sealing test area, making the sealing performance testing more standardized and consistent. This design allows for flexible adjustment of the test area width according to different experimental needs, further improving the controllability and accuracy of the test. It helps to comprehensively evaluate the performance of the vibration isolator under different sealing conditions, while also optimizing the structure of the device and improving the reliability and repeatability of the experimental results.

[0023] Preferably, the inner wall of the observation tube 5 is coated with an anti-fog layer 8 to ensure clear visibility in high-temperature or humid environments.

[0024] By coating the inner wall of the observation cylinder 5 with an anti-fog layer 8, this design effectively solves the problem of blurred vision caused by water vapor condensation in high-temperature or humid environments. The anti-fog layer prevents water droplets from forming on the inner wall surface, ensuring a clear field of view at all times, improving observation accuracy and ease of operation. Especially under complex or extreme environmental conditions, this design guarantees stability and accuracy during the observation process, enabling users to continuously obtain a clear view, facilitating real-time monitoring and precise measurement, and enhancing the practicality and reliability of the device.
