Abstract
Description
Technical Field
[0001] This utility model relates to a building platform for take-off and landing of vertical take-off and landing aircraft, belonging to the field of building platform technology. Background Technology
[0002] As ground traffic congestion in large cities intensifies, the demand for air cargo transportation and air travel becomes more urgent, giving rise to the low-altitude economy. The low-altitude economy is a comprehensive new economic form that takes civilian manned and unmanned aircraft as the main body and low-altitude flight activities in multiple scenarios such as carrying people, cargo and other operations as the driving force, and promotes the integrated development of commercial activities or public service sectors.
[0003] With the rapid development of the low-altitude economy and the continuous expansion of its application scenarios, short-haul helicopter travel has become increasingly common, and the use of drones for cargo delivery services such as express delivery and medical supply transport has become more convenient and efficient. For this new type of low-altitude economic transportation, the construction of facilities that can accommodate the take-off, landing, and parking of small manned helicopters and drones is an indispensable infrastructure guarantee for meeting the needs of low-altitude flight.
[0004] Currently, the infrastructure for the low-altitude economy includes ground helipads and rooftop parking platforms. Helicopters or drones can be parked on ground helipads or rooftop platforms. On ground helipads, each aircraft is laid flat, occupying a large space and requiring a large area of land, which is especially difficult to achieve in many cities with limited land. Existing cities have many tall buildings, which can be used for parking on rooftop platforms. However, these platforms are usually open-air, and aircraft stored in the open are exposed to wind and sun, which can affect their lifespan over time. In addition, aircraft maintenance also needs to be carried out in the open, making maintenance inconvenient.
[0005] In addition, as a lifting platform specifically designed for vertical take-off and landing aircraft, the aircraft usually takes off and lands on the top floor. When not in flight, the aircraft needs to be moved to the next floor for storage or maintenance via the lifting mechanism. In this case, the lifting well on the top floor needs to be covered with a rainproof cover. Utility Model Content
[0006] This utility model addresses the shortcomings of existing technologies by providing a construction platform for the take-off and landing of vertical take-off and landing aircraft.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A building platform for take-off and landing of a vertical take-off and landing aircraft includes a building body, a parking platform is provided on the top of the building body, a fixed parking position and an lifting parking position are provided on the parking platform, an lifting well is provided on the parking platform, the lifting parking position is located at the lifting well, and a lifting platform is provided at the lifting parking position. It also includes a waterproof shielding device installed at the elevator shaft opening. The waterproof shielding device includes a telescopic roller shutter, a left guide rail and a right guide rail located on the left and right sides of the telescopic roller shutter, and a roller shutter box for storing the telescopic roller shutter. The waterproof shielding device can close the elevator shaft opening after the elevator platform enters the building body. The left guide rail is a lower side guide rail, and the right guide rail is 2-20cm higher than the left guide rail; or, the right guide rail is a lower side guide rail, and the left guide rail is 2-20cm higher than the right guide rail.
[0008] The beneficial effects of this utility model are as follows: The parking platform not only has fixed parking positions but also lifting parking positions. The lifting platform of the lifting parking position can lower the aircraft into the building. Especially when the aircraft is parked for a long time, it can be moved into the building for parking. Maintenance of the aircraft can also be carried out inside the building. In this way, the aircraft can make more flexible use of the space on the top of the building and inside the building when parking, avoiding the problems of wind and sun exposure caused by open-air storage. It is especially suitable for urban environments with limited land. The waterproof shielding device can close the lifting shaft after the lifting platform enters the building. The left-high-right or right-high-left-low of the retractable roller shutter facilitates drainage. The height difference between the left and right guide rails makes it easy for water on the retractable roller shutter to drain when the waterproof shielding device is closed, improving the waterproof effect of the waterproof shielding device and protecting the aircraft, retractable roller shutter and facilities inside the building from the effects of severe weather.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the left guide rail is a lower side guide rail, and the right guide rail is 8-15cm higher than the left guide rail; or, the right guide rail is a lower side guide rail, and the left guide rail is 8-15cm higher than the right guide rail.
[0011] The beneficial effects of adopting the above-mentioned further solution are that the 8-15cm height difference between the left and right guide rails ensures smooth drainage when the retractable roller shutter is closed, facilitates the opening and closing of the lifting well of the retractable roller shutter, improves the waterproof performance of the waterproof shielding device, guides and drains rainwater falling on the retractable roller shutter, prevents rainwater from flowing back into the building, protects the aircraft and internal facilities from damage, extends the service life of the waterproof shielding device, and reduces maintenance costs.
[0012] Furthermore, a baffle is provided inside the lower side guide rail.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the baffle can prevent the telescopic roller blind from sliding to the lower side, limit the lower side position of the telescopic roller blind, ensure that the telescopic roller blind is stably positioned between the left and right guide rails, and avoid the problem of the waterproof shielding device not covering properly due to the sliding of the telescopic roller blind.
[0014] Furthermore, the telescopic roller blind includes multiple parallel curtain panels, and each curtain panel has a slider or roller at both ends that can move within the left and right guide rails, respectively. Ball bearings are provided between the baffle and the axle of the slider or roller.
[0015] The beneficial effects of adopting the above-mentioned further solution are that the sliders or rollers at both ends of the curtain panel allow the retractable roller blind to move on the left and right guide rails in a sliding or rolling manner, making the opening and closing of the retractable roller blind smoother, reducing friction and jamming, and improving the flexibility and reliability of the opening and closing of the retractable roller blind; the ball bearings between the baffle and the slider or the roller axle make the friction between the slider or roller and the baffle a rolling friction, which can reduce the friction between the slider or roller and the baffle and reduce the wear between the retractable roller blind and the baffle.
[0016] Furthermore, the ball bearing is disposed on the baffle plate, or the ball bearing is disposed on the axle of the slider or roller.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the ball bearings can be set on the baffle, with multiple ball bearings arranged on the side surface of the baffle near the telescopic roller blind. When the axle of the slider or roller rolls on the baffle, the rolling action of the ball bearings transforms friction into rolling friction, making the movement of the slider or roller on the lower side guide rail easier and smoother, reducing wear. Of course, the ball bearings can also be set on the axle of the slider or roller, which can also achieve the effect of rolling friction. During the contact movement between the axle of the slider or roller and the baffle, the friction between the two can be effectively reduced, improving the operational stability of the telescopic roller blind.
[0018] Furthermore, the lower side guide rail is also provided with a water guide hole, and the outlet of the water guide hole is connected to the drainage pipe of the building.
[0019] The beneficial effect of adopting the above-mentioned further solution is that, in order to facilitate the timely drainage of rainwater and other water from the low-side guide rail, multiple water guide holes are set on the low-side guide rail, which can promptly guide and drain the water flowing to the low-side guide rail. The water is then smoothly discharged from the building body through the building's drainage pipes, effectively preventing water accumulation in the low-side guide rail and ensuring the normal operation of the entire building platform.
[0020] Furthermore, the guide rail bodies of both the left and right guide rails are C-shaped.
[0021] The beneficial effect of adopting the above-mentioned further solution is that the C-shaped guide rail provides guidance, limit and support for the opening and closing of the telescopic roller blind, ensuring that the telescopic roller blind runs smoothly on the left and right guide rails and is not prone to shaking.
[0022] Furthermore, the roller shutter box is suspended from the bottom of the parking platform.
[0023] The advantages of adopting the above-mentioned further solution are that the roller shutter box is suspended inside the building, and the retractable roller shutter can be stored inside when not in use. Since the roller shutter box is not located on the parking platform, it does not occupy space on the parking platform and does not interfere with the takeoff and landing of the aircraft. When in use, the retractable roller shutter can close the lift shaft, effectively blocking external factors such as rainwater and sandstorms from intruding on the aircraft and the building. When not in use, the retractable roller shutter can be stored inside the roller shutter box, without interfering with the raising of the lift platform or the parking of the aircraft.
[0024] Furthermore, the lifting platform, under the action of the lifting mechanism, can enter the interior of the building along the lifting channel, and is used to carry the vertical take-off and landing aircraft for parking and maintenance inside the building.
[0025] The beneficial effects of adopting the above-mentioned further solution are that the lifting and lowering of the platform is achieved through a lifting mechanism. When the aircraft needs maintenance or long-term parking, the lifting mechanism is activated, and the platform can carry the aircraft down into the building for maintenance or parking. When the aircraft needs to take off, the lifting mechanism is activated, and the platform rises, carrying the aircraft to the parking platform to prepare for takeoff. The interior of the building can provide good conditions for the maintenance and long-term parking of the aircraft, reducing the impact of external factors on the aircraft.
[0026] Furthermore, the lifting mechanism includes a lifting frame, a lifting drive mechanism for driving the lifting frame to move up and down, and a pair of lifting rails for guiding the lifting frame. The lifting platform is disposed on the lifting frame, and the lifting frame and the lifting rails slide or roll together.
[0027] The beneficial effect of adopting the above-mentioned further solution is that, driven by the lifting drive mechanism, the lifting frame can move stably up and down along the lifting track, ensuring the stability of the lifting platform during the lifting process, and also meeting the requirement that the lifting platform and the parking platform are flush.

Detailed Implementation
[0029] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0030] like Figures 1-6 As shown, a building platform for take-off and landing of a vertical take-off and landing aircraft includes a building body 1. The top of the building body 1 is provided with a parking platform 2. The parking platform 2 is provided with a fixed parking position 3 and an lifting parking position 4. The parking platform 2 is provided with a lifting well opening. The lifting parking position 4 is located at the lifting well opening. The lifting parking position 4 is provided with a lifting platform 7. It also includes a waterproof shielding device 5 installed at the elevator shaft opening. The waterproof shielding device 5 includes a telescopic roller shutter 501, a left guide rail 502 and a right guide rail 503 located on the left and right sides of the telescopic roller shutter 501, and a roller shutter box 504 for storing the telescopic roller shutter 501. The waterproof shielding device 5 can close the elevator shaft opening after the elevator platform 7 enters the building body 1. The telescopic roller shutter 501 of the waterproof shielding device 5 can extend to shield the elevator shaft opening. The left guide rail 502 is a low-side guide rail, and the right guide rail 503 is 2-20cm higher than the left guide rail 502; or, the right guide rail 503 is a low-side guide rail, and the left guide rail 502 is 2-20cm higher than the right guide rail 503.
[0031] like Figure 3 As shown, the right guide rail 503 is higher than the left guide rail 502.
[0032] The left guide rail 502 is a low-side guide rail, and the right guide rail 503 is 8-15cm higher than the left guide rail 502; or, the right guide rail 503 is a low-side guide rail, and the left guide rail 502 is 8-15cm higher than the right guide rail 503. This 8-15cm height difference between the left guide rail 502 and the right guide rail 503 (e.g., 8cm, 10cm, 15cm, etc.) ensures smooth drainage when the retractable roller shutter 501 is closed, facilitates the opening and closing of the lifting well of the retractable roller shutter 501, improves the waterproof performance of the waterproof shielding device 5, guides and drains rainwater falling on the retractable roller shutter 501, prevents rainwater from flowing back into the building 1, protects the aircraft and its internal facilities from damage, extends the service life of the waterproof shielding device 5, and reduces maintenance costs.
[0033] A baffle 505 is provided inside the lower side guide rail. The baffle 505 can prevent the telescopic roller blind 501 from sliding to the lower side, limit the lower side position of the telescopic roller blind 501, and ensure that the telescopic roller blind 501 is stably positioned between the left guide rail 502 and the right guide rail 503, thus avoiding the problem of the waterproof covering device 5 not covering properly due to the sliding of the telescopic roller blind 501.
[0034] The retractable roller blind 501 includes multiple parallel curtain panels. Each curtain panel has a slider or roller 507 at both ends, capable of moving within the left guide rail 502 and right guide rail 503. A ball bearing 506 is positioned between the baffle 505 and the axle of the slider or roller 507. The slider or roller 507 at both ends of the curtain panels allows the retractable roller blind 501 to move along the left guide rail 502 and right guide rail 503 via a sliding or rolling motion, resulting in smoother opening and closing, reduced friction and jamming, and improved flexibility and reliability. The ball bearing 506 between the baffle 505 and the slider or roller 507 axle ensures that the friction between the slider or roller 507 and the baffle 505 is rolling friction, reducing friction between them and thus reducing wear between the retractable roller blind 501 and the baffle 505.
[0035] The ball bearing 506 is disposed on the baffle 505, or the ball bearing 506 is disposed on the axle of the slider or roller 507. The ball bearing 506 can be disposed on the baffle 505, with multiple balls bearing 506 disposed on the side surface of the baffle 505 near the telescopic roller blind 501. When the slider or roller 507 rolls on the baffle 505, the rolling action of the ball bearing 506 transforms friction into rolling friction, making the movement of the slider or roller 507 on the lower side guide rail easier and smoother, reducing wear. Alternatively, the ball bearing 506 can also be disposed on the axle of the slider or roller 507, achieving the same rolling friction effect. During the contact movement between the slider or roller 507 and the baffle 505, the friction between them is effectively reduced, improving the operational stability of the telescopic roller blind 501.
[0036] The lower side guide rail is also provided with a water guide hole 508, the outlet of which is connected to the drainage pipe of the building body 1. In order to facilitate the timely discharge of rainwater and other water from the lower side guide rail, multiple water guide holes 508 are also provided on the lower side guide rail to promptly guide and discharge water flowing towards the lower side guide rail. The water is then smoothly discharged outside the building body 1 through the drainage pipe of the building body 1, effectively preventing water accumulation in the lower side guide rail and ensuring the normal operation of the entire building platform.
[0037] The guide rails of the left guide rail 502 and the right guide rail 503 are both C-shaped. The C-shaped guide rails provide guidance, limit and support for the opening and closing of the telescopic roller blind 501, ensuring that the telescopic roller blind 501 runs smoothly on the left guide rail 502 and the right guide rail 503 and is not prone to shaking.
[0038] The roller shutter box 504 is suspended from the bottom of the parking platform 2. The roller shutter box 504 is suspended inside the building 1, and the retractable roller shutter 501 can be stored inside when not in use. The roller shutter box 504 is not located on the parking platform 2, thus not occupying space on the platform 2, and does not interfere with the takeoff and landing of the aircraft. When in use, the retractable roller shutter 501 can close the elevator shaft, effectively blocking rainwater, sandstorms, and other external factors from intruding into the aircraft and the building 1. When not in use, the retractable roller shutter 501 can be stored inside the roller shutter box 504, without interfering with the raising of the elevator platform 7 or the parking of the aircraft.
[0039] The lifting platform 7, under the action of the lifting mechanism, can enter the interior of the building 1 along the lifting channel to carry the vertical take-off and landing aircraft for parking and maintenance inside the building 1. The lifting of the lifting platform 7 is achieved through the lifting mechanism. When the aircraft needs maintenance or long-term parking, the lifting mechanism is activated, and the lifting platform 7 can carry the aircraft down into the building 1 for maintenance or parking. When the aircraft needs to take off, the lifting mechanism is activated, and the lifting platform 7 rises, carrying the aircraft to the parking platform 2, preparing for the aircraft's take-off. The interior of the building 1 provides good conditions for the maintenance and long-term parking of the aircraft, reducing the impact of external factors on the aircraft.
[0040] The lifting mechanism includes a lifting frame 6, a lifting drive mechanism for driving the lifting frame 6 up and down, and a pair of lifting rails 12 for guiding the lifting frame 6. The lifting platform 7 is mounted on the lifting frame 6, and the lifting frame 6 and the lifting rails 12 are in sliding or rolling cooperation. Driven by the lifting drive mechanism, the lifting frame 6 can move stably up and down along the lifting rails 12, ensuring the stability of the lifting platform 7 during the lifting process and meeting the requirement that the lifting platform 7 is flush with the parking platform 2.
[0041] The lifting drive mechanism includes a hydraulic drive cylinder 8, a transmission sprocket 9, and a transmission chain 10. The transmission sprocket 9 is rotatably mounted on a balance beam 11. The piston rod of the hydraulic drive cylinder 8 is connected to the balance beam 11. One end of the transmission chain 10 is fixed, and the other end passes around the transmission sprocket 9 and is connected to the lifting frame 6.
[0042] This utility model's parking platform not only has a fixed parking position 3, but also a lifting parking position 4. The lifting platform 7 of the lifting parking position 4 can lower the aircraft into the building 1. Especially when the aircraft is parked for a long time, it can be moved into the building 1 by the lifting mechanism. The aircraft can also be maintained inside the building 1. In this way, the aircraft can make more flexible use of the space on the top of the building 1 and inside it when parked, avoiding the problems of wind and sun exposure caused by open-air storage. It is especially suitable for urban environments with limited land. The waterproof shielding device 5 can close the lifting well after the lifting platform 7 enters the building 1. The purpose of the telescopic roller shutter 501 being higher on the left and lower on the right or vice versa is to facilitate drainage. The height difference between the left guide rail 502 and the right guide rail 503 makes it easy for water on the telescopic roller shutter 501 to drain when the waterproof shielding device 5 is closed, improving the waterproof effect of the waterproof shielding device 5 and protecting the aircraft, the telescopic roller shutter 501 and the facilities inside the building 1 from the effects of severe weather.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
