Description

Technical Field

[0001] This utility model belongs to the technical field of mobile airport supporting equipment, and specifically relates to a folding hangar for mobile airports. Background Technology

[0002] A mobile airport is a highly maneuverable vertical takeoff and landing platform for aircraft. Through an innovative vehicle-mounted, mobile design, the product enables the airport to be flexibly relocated to meet changing needs.

[0003] Mobile airports typically need to be deployed in the field. However, existing mobile airports generally lack convenient hangars, making it impossible to effectively protect the mobile airport and its aircraft from wind, rain, and sun. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a foldable hangar for mobile airports.

[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used: A folding hangar for a mobile airport includes a base frame with several arc-shaped or U-shaped support frames rotatably connected to it. A tarpaulin is provided between the support frames and the base frame. The support frames can unfold the tarpaulin to form a hemispherical cover. The support frames are connected to a retraction and unfolding drive structure.

[0006] The folding hangar of this utility model mainly consists of a base frame and several support frames. The support frames can be brought close to the base frame for storage or rotated in the opposite direction to unfold. In the fully unfolded state, the spacing between each support frame is basically the same, and the tarpaulin is fully extended, forming a hemispherical cover. The cover contains space for accommodating the mobile airport and its aircraft, which can protect the mobile airport and aircraft. The unfolding drive structure is used to drive the unfolding and folding of the support frames, making unfolding and folding convenient.

[0007] In the aforementioned mobile airport's folding hangar, the base frame is shaped to match the support frame, being arc-shaped or U-shaped. The support frame includes a first support frame located on the side furthest from the base frame, a second support frame located on the side closest to the base frame, and several third support frames located between the first and second support frames. The base frame is fixed to the installation ground.

[0008] The base frame has the same shape as the support frame, which is equivalent to taking a support frame as the base frame. The base frame is fixed to the installation ground to ensure the overall installation stability.

[0009] In the aforementioned mobile airport's collapsible hangar, the underframe is fixed to the installation ground by helical pile anchors or chemical anchors.

[0010] The base frame can be fixed in different ways depending on the ground conditions. On hard installation ground, M20 chemical anchors with a pull-out force ≥30kN can be used. On soft installation ground, helical pile anchors with a depth ≥1.5m can be used to ensure stability. In addition, on special base surfaces that cannot be damaged, the frame can also be fixed by adding a load-bearing plate to the column base plate and applying weights.

[0011] In the aforementioned folding hangar of the mobile airport, the first support frame is in contact with the installation ground when fully unfolded, and a fixing part is provided on the installation ground. The first support frame is detachably connected to the fixing part.

[0012] When fully extended, the first support frame and the base frame are in contact with the installation ground, while the remaining support frames are distributed in a fan shape between them. A fixing part adapted to the position of the first support frame is set on the installation ground. The first support frame is detachably fixed to the fixing part, which can be achieved by means such as bolts or hooks, ensuring the overall deployment stability and installation stability. At the same time, the detachable fixing method of the first support frame also facilitates the opening and closing of the folding hangar.

[0013] In the aforementioned folding hangar of the mobile airport, the ends of the base frame and support frame are rotatably connected to a rotating shaft. The first support frame furthest from the base frame is connected to the retraction drive structure. A rotation angle limiting structure is provided between adjacent support frames and between the second support frame closest to the base frame and the base frame.

[0014] The retraction drive structure is used to control the rotation of the first support frame, and the rotation angle limiting structure is used to ensure the maximum included angle between each support frame, so that each support frame can be unfolded to the corresponding angle. When the first support frame rotates and unfolds, the support frames connected to it will be pulled out in sequence, ensuring the effective unfolding of the whole and avoiding strong pulling on the tarpaulin.

[0015] In the aforementioned mobile airport's folding hangar, the retraction drive structure includes a geared motor, a transmission sleeve is provided at the end of the first support frame, the rotating shaft passes through the transmission sleeve, and a transmission gear is provided on the transmission sleeve, which meshes with the drive gear of the geared motor.

[0016] The end of the first support frame is provided with a driven gear through a transmission sleeve. The driven gear meshes with the drive gear of the geared motor to achieve the effect of driving the first support frame to rotate through the geared motor.

[0017] In the aforementioned folding hangar of the mobile airport, the geared motor is fixed to the base frame and located inside the housing. The ends of the support frames other than the first support frame are provided with connecting holes, which are rotatably connected to the rotating shaft or transmission sleeve.

[0018] The ends of the support frames between the first support frame and the base frame are rotatably connected to the rotating shaft through connecting holes. When the end of the first support frame is located at the innermost side of the ends of other support frames, that is, when the end is closest to the geared motor, the connecting hole is directly rotated on the rotating shaft. Otherwise, the connecting hole at the end of the support frame between the first support frame and the geared motor is rotatably connected to the transmission sleeve, ensuring the free rotation of the intermediate support frame.

[0019] In the aforementioned folding hangar of the mobile airport, the rotation angle limiting structure includes cables, with cables connecting adjacent support frames and between the second support frame and the base frame.

[0020] The two ends of the cable are connected to adjacent support frames, or to the second support frame and the base frame, to limit the maximum angle of rotation of each support frame and ensure that the support frames are evenly distributed when fully extended.

[0021] In the aforementioned folding hangar of the mobile airport, one or more cables are provided, symmetrically distributed on both sides of the arc top of the support frame; the length of the cables is adapted to the spacing between adjacent support frames when fully extended.

[0022] One or more cables are installed, symmetrically distributed at both ends with the apex of the arc as the reference surface to ensure uniform stress distribution.

[0023] In the aforementioned mobile airport's folding hangar, the geared motor of the retraction drive structure is also communicatively connected to the wireless control components. The support frame and the base frame are provided with a locking structure on the side. The locking structure includes a locking plate. The locking plate has several radially extending limiting grooves distributed in an arc shape. The position of the limiting grooves is adapted to the position of the support frame when fully extended. The connecting section of the support frame and the base frame is locked in the limiting groove. The tarpaulin includes a waterproof tarpaulin, which is detachably fixed to the outside of the support frame and the base frame.

[0024] Wireless control components are used to remotely control the geared motor's operation, improving operational convenience. When the support frame is fully extended, the locking plate further limits the angle between the support frames, ensuring stability in the extended state. The connecting sections of the support frames are engaged in limiting grooves, effectively restricting rotation, and this fit is flexible and removable. The tarpaulin is waterproof, ensuring waterproofing; it is fixed to the outside, protecting the support frame and base, and this fixing is also flexible and removable for easy replacement when needed.

[0025] Compared with the prior art, the present invention has the following main advantages: 1. The support frame can be retracted by bringing it close to the base frame, or it can be rotated in the opposite direction to unfold. In the fully unfolded state, the spacing between each support frame is basically the same, and the tarpaulin is fully extended, forming a hemispherical cover. The cover contains space for accommodating the mobile airport and the aircraft on it, which can protect the mobile airport and the aircraft. The unfolding and retraction drive structure is used to drive the unfolding and retraction of the support frame, which is convenient.

[0026] 2. A driven gear is provided at the end of the first support frame through a transmission sleeve. The driven gear meshes with the drive gear of the geared motor to achieve the effect of driving the first support frame to rotate through the geared motor.

[0027] 3. The two ends of the cable are connected to adjacent support frames, or to the second support frame and the base frame, to limit the maximum angle of rotation of each support frame and ensure that each support frame is evenly distributed when fully extended.

[0028] 4. When the support frame is fully extended, the locking plate can further limit the included angle between the support frames, ensuring the stability of the extended state. The connecting section of the support frame is locked in the limiting groove, which can restrict the rotation of the support frame. Moreover, this fit has flexible disassembly.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] Specific implementation examples Figures 1-5As shown, the folding hangar of this mobile airport includes a base frame 1, on which several U-shaped support frames 2 are rotatably connected. A tarpaulin 3 is provided between the support frames 2 and the base frame 1. The support frames 2 can unfold the tarpaulin 3 to form a hemispherical cover 4. The support frames 2 are connected to the unfolding drive structure 5.

[0033] Specifically, this folding hangar mainly consists of a base frame 1 and several support frames 2. The support frames 2 can be folded up against the base frame 1 or rotated in the opposite direction to unfold. In the fully unfolded state, the spacing between the support frames 2 is basically the same, and the tarpaulin 3 is fully extended, forming a hemispherical cover 4. The cover 4 contains space for accommodating the mobile airport and its aircraft, protecting the mobile airport and aircraft. The unfolding drive structure 5 is used to drive the unfolding and folding of the support frames 2, making unfolding and folding convenient. When fully unfolded, the first support frame 7 is in contact with the mounting ground 6. The mounting ground 6 is provided with a fixing part 10, and the first support frame 7 is detachably connected to the fixing part 10.

[0034] like Figure 1 , Figure 4 As shown, the base frame 1 is U-shaped to match the support frame 2. The support frame 2 includes a first support frame 7 located on the side furthest from the base frame 1, a second support frame 8 located on the side closest to the base frame 1, and several third support frames 9 located between the first support frame 7 and the second support frame 8. The base frame 1 is fixed to the mounting ground 6. Specifically, the base frame 1 has the same shape as the support frame 2, which is equivalent to taking one support frame 2 as the base frame 1. The base frame 1 is fixed to the mounting ground 6 (the fixing details are not shown in the figure), ensuring the overall installation stability. When fully unfolded, both the first support frame 7 and the base frame 1 are in contact with the mounting ground 6, and the remaining support frames 2 are distributed between them in a fan shape. A fixing part 10 adapted to the position of the first support frame 7 is provided on the mounting ground 6. The first support frame 7 is detachably fixed to the fixing part 10, specifically by bolts, ensuring the overall unfolding stability and installation stability. At the same time, the detachable fixing method of the first support frame 7 also facilitates the opening and closing of the folding hangar.

[0035] like Figures 1-4As shown, the ends of the base frame 1 and support frame 2 are rotatably connected to the rotating shaft 11. The first support frame 7, furthest from the base frame 1, is connected to the retraction drive structure 5. Rotation angle limiting structures 12 are provided between adjacent support frames 2 and between the second support frame 8, closest to the base frame 1, and the base frame 1. The retraction drive structure 5 includes a geared motor (not specifically shown in the figure). The end of the first support frame 7 is provided with a transmission sleeve 13, through which the rotating shaft 11 passes. The transmission sleeve 13 is provided with a transmission gear (not specifically shown in the figure), which meshes with the drive gear of the geared motor. The geared motor is fixed to the base frame 1 and located inside the cover 4. The ends of the second and third support frames 8 are provided with connecting holes 15, which are rotatably connected to the rotating shaft 11 or the transmission sleeve 13.

[0036] Specifically, the retraction drive structure 5 controls the rotation of the first support frame 7, and the rotation angle limiting structure 12 ensures the maximum included angle between each support frame 2, allowing each support frame 2 to unfold to the corresponding angle. When the first support frame 7 rotates and unfolds, the connected support frames 2 will be pulled out in sequence, ensuring effective overall unfolding and avoiding excessive pulling on the tarpaulin 3. The end of the first support frame 7 is equipped with a driven gear through the transmission sleeve 13. This driven gear meshes with the drive gear of the reduction motor, achieving the effect of driving the first support frame 7 to rotate through the reduction motor.

[0037] In this embodiment, the rotation angle limiting structure 12 includes a cable 16, which connects adjacent support frames 2 and between the second support frame 8 and the base frame 1. One cable 16 is provided, connected to the apex of the arc, and the length of the cable 16 is adapted to the spacing between adjacent support frames 2 when fully extended.

[0038] Specifically, the two ends of the cable 16 are connected to adjacent support frames 2, or to the second support frame 8 and the base frame 1, to limit the maximum angle of rotation of each support frame 2 and ensure that each support frame 2 is evenly distributed when fully extended.

[0039] As a further optimization of this embodiment, the geared motor of the retraction drive structure 5 is also connected to the wireless control component; the support frame 2 and the base frame 1 are provided with a locking structure on their sides, the locking structure includes a locking plate 17, and a plurality of radially extending limiting grooves 18 are distributed in an arc shape on the locking plate 17. The position of the limiting grooves 18 is adapted to the position of the support frame 2 when fully extended, and the connecting section 19 of the support frame 2 and the base frame 1 is locked in the limiting grooves 18; the tarpaulin 3 includes a waterproof rain cloth, and the tarpaulin 3 is detachably fixed to the outside of the support frame 2 and the base frame 1.

[0040] Specifically, the wireless control component is used to remotely control the operation of the geared motor, improving operational convenience. When the support frame 2 is fully extended, the locking plate 17 further limits the included angle between the support frames 2, ensuring stability in the extended state. The connecting section 19 of the support frame 2 is engaged in the limiting groove 18, effectively restricting the rotation of the support frame 2, and this fit is flexible and removable. The tarpaulin 3 is a waterproof raincoat, ensuring waterproof performance. It is fixed to the outside, protecting the support frame 2 and the base frame 1, and this fixing is flexible and removable, facilitating replacement when needed.

[0041] Specific working principle: During installation, the base frame 1 is fixed to the installation ground 6. Then, the reduction motor is controlled to drive the first support frame 7 to rotate. Under the action of the cable 16, the first support frame 7 pulls up the subsequent support frames 2 in sequence. The first support frame 7 finally touches the installation ground 6 and is flush with the base frame 1. Then, the first support frame 7 and the fixing part 10 are connected and fixed, and the unfolding is completed. In order to further increase the stability of the unfolded state, the limiting groove 18 is aligned with the connecting section 19 at the end of the support frame 2, and the locking plate 17 is snapped onto the support frame 2. The connecting section 19 is locked in the corresponding limiting groove 18.
