Description

Technical Field

[0001] The utility model belongs to the technical field of vibration isolation, and in particular relates to a three-dimensional vibration isolation support for a rooftop helipad. Background Art

[0002] Electric vertical take-off and landing (eVTOL) vehicles, with their exceptional performance, are increasingly becoming a focal point. A revolutionary leap forward in aviation, eVTOLs integrate cutting-edge concepts, clean energy, advanced materials, and technologies, foreshadowing the core form of future urban air mobility systems. Globally, the research and development of low-altitude economy-related aircraft and their supporting facilities continues to surge, opening up a new frontier in the international aviation technology competition. Against this backdrop, aprons, as critical infrastructure supporting eVTOL operations, urgently require technological innovation to improve construction efficiency and user experience, aligning with the low-altitude economy's demand for high-quality services.

[0003] Currently, the design and construction of rooftop helipads in my country largely follow the traditional helicopter landing model, primarily employing cast-in-place concrete structures. However, this structure is not only heavy, posing challenges to the building's earthquake and wind resistance, but also comes with inherent drawbacks such as long construction periods, significant environmental pollution, and difficulty in flexible demolition, modification, or upgrading. More importantly, the vibrations generated by helicopters taking off and landing on rooftops can easily be transmitted into the building through the direct connection between the cast-in-place concrete and the main structure, affecting not only the comfort of the living or working environment but also interference with precision equipment in medical institutions, impacting their normal operation.

Figure 2 This is a bottom view of the three-dimensional vibration isolation support for the rooftop helipad of the utility model. Figure 3 This is a top view of a three-dimensional vibration isolation support for a rooftop helipad according to the present invention. A three-dimensional vibration isolation support for a rooftop helipad comprises an upper connecting plate 1, a lower connecting plate 2, a first vertical vibration isolation system 3, a rubber pad 4, a middle connecting plate 5, and a plurality of second vertical vibration isolation systems 6. The first vertical vibration isolation system 3 is installed between the upper connecting plate 1 and the lower connecting plate 2. A first through hole is provided in the middle of the rubber pad 4. The rubber pad 4 is sleeved on the outside of the first vertical vibration isolation system 3 through the first through hole, and the rubber pad 4 is installed at the bottom of the upper connecting plate 1. A second through hole is provided in the middle of the middle connecting plate 5. The middle connecting plate 5 is sleeved on the outside of the first vertical vibration isolation system 3 through the second through hole, and the middle connecting plate 5 is installed at the bottom of the rubber pad 4. The plurality of second vertical vibration isolation systems 6 are arranged in a circle with equal spacing around the first vertical vibration isolation system 3, and the second vertical vibration isolation systems 6 are installed between the middle connecting plate 5 and the lower connecting plate 2.

[0033] The upper connecting plate 1 and the lower connecting plate 2 are respectively used to connect to the main structure and the helipad. The three-dimensional vibration isolation support for the rooftop helipad of this utility model is installed between the main structure and the helipad. To facilitate installation, in one embodiment, mounting holes 7 are provided at the four corners of the upper connecting plate 1 and the lower connecting plate 2. These mounting holes 7 allow the upper connecting plate 1 and the lower connecting plate 2 to be bolted to the main structure and the helipad, respectively, enabling rapid assembly and construction, improving construction efficiency.

[0034] When subjected to the impact vibration caused by the takeoff and landing of aircraft on the rooftop helipad, the vibration is transmitted through the helipad to the three-dimensional vibration isolation support for the rooftop helipad of the utility model, and then the first vertical vibration isolation system 3, the rubber pad 4 and the plurality of second vertical vibration isolation systems 6 absorb energy and reduce the vibration, thereby ensuring the vibration comfort of the main structure, thereby effectively reducing the vibration problem of the main structure caused by the takeoff and landing of aircraft on the rooftop and improving the vibration comfort of the structure.

[0035] Specifically, the first vertical vibration isolation system 3 and the second vertical vibration isolation system 6 perform both load-bearing and vibration-damping functions, effectively regulating the vertical modal frequency of the structure. They also effectively provide vertical load-bearing capacity and reduce the vertical stiffness of the apron. Arranging the first vertical vibration isolation system 3 and several second vertical vibration isolation systems 6 in parallel also provides greater lateral stiffness, effectively enhancing the lateral resistance of the support. In one embodiment, both the first vertical vibration isolation system 3 and the second vertical vibration isolation system 6 utilize coil springs. In one embodiment, there are four second vertical vibration isolation systems 6.

[0036] The rubber pad 4 can reduce the vertical stiffness of the support and provide vibration damping, and its damping effect can absorb impact vibration energy. In one embodiment, the rubber pad 4 is connected to the upper connecting plate 1 by bolts. This arrangement facilitates the installation and removal of the rubber pad 4. In one embodiment, a third groove 10 for placing the rubber pad 4 is provided at the bottom of the upper connecting plate 1. The rubber pad 4 is restricted by the third groove 10 to ensure that the placement position of the rubber pad 4 is accurate, which facilitates the connection of the rubber pad 4 and the upper connecting plate 1 by bolts. In one embodiment, the rubber pad 4 adopts a high-damping thick-fleshed rubber pad 4. High damping can effectively absorb vibration energy, and thick-fleshed means that the thickness of the rubber pad 4 is large, it has good pressure-bearing capacity and buffering capacity, and can withstand greater loads and impacts.

[0037] In one embodiment, the top of the lower connecting plate 2 is provided with a first groove 8 for accommodating the first vertical vibration isolation system 3 and a plurality of second grooves 9 for accommodating a plurality of second vertical vibration isolation systems 6. The first groove 8 and the plurality of second grooves 9 are provided on the top of the lower connecting plate 2. The first groove 8 constrains the first vertical vibration isolation system 3, ensuring that the first vertical vibration isolation system 3 is accurately positioned and prevents lateral shifting. The plurality of second grooves 9 respectively constrain the plurality of second vertical vibration isolation systems 6, ensuring that the second vertical vibration isolation systems 6 are accurately positioned and prevented from lateral shifting.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
