Description

Technical Field

[0001] This utility model relates to the field of helicopter hangar technology, specifically to a telescopic mobile hangar. Background Technology

[0002] With the diversification of functions in urban high-rise buildings, the application scenarios of rooftop helipads are gradually expanding to areas such as medical rescue, fire emergency response, and business travel. However, the rooftop environment is characterized by limited space, high exposure, and complex weather conditions, making it difficult for existing helicopter protective hangar technologies to fully adapt. Among the known technologies, one can refer to the intelligent helicopter folding hangar disclosed in Chinese Utility Model Patent Application No. CN201821463444.9, which achieves helicopter shelter through a pre-embedded base and an unfolding structure of steel pipe supports.

[0003] However, while the above technologies can cope with sudden rain or sun exposure, their design is mainly for ground-based helipads and still has certain shortcomings for helipads applied to buildings. For example, the wind pressure on the roof is significantly higher than that on the ground, and the existing inverted "U"-shaped steel pipe supports and tensile membrane structures are prone to resonance or tearing under strong winds, especially with low reliability of protection during typhoons or thunderstorms. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a telescopic mobile hangar.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The retractable mobile hangar includes two sets of symmetrical retractable sunroom structures that can move relative to each other to form a closed state to shield helicopters and an extended state to allow helicopters to take off and land.

[0007] The helicopter landing platform, located between two sets of symmetrical retractable sunroom structures, is a disc-shaped structure with a diameter 2 to 2.5 times that of the helicopter rotor.

[0008] The lifting mechanism is used to raise the helicopter landing platform. It is installed at the bottom of the helicopter landing platform so that the helicopter rotor is level with or higher than the roof of the retractable sunroom.

[0009] A circular mounting groove is made in the ground, and a drainage system is connected to the bottom of the mounting groove. The diameter of the mounting groove is larger than the diameter of the helicopter landing platform. The lifting mechanism is fixed in the mounting groove, and the helicopter landing platform is installed on top of the lifting mechanism. When the lifting mechanism is lowered to its lowest position, the top plane of the helicopter landing platform is flush with the ground.

[0010] In this invention, the lifting mechanism is provided in three sets, arranged in an equilateral triangle below the helicopter landing platform, and operates synchronously.

[0011] In this utility model, the lifting mechanism consists of a base, a cross bracket, and a connecting seat. The cross bracket is movably mounted on the base. Of the four ends, the upper and lower ends on the same side are rotatably connected to the connecting seat and the base, respectively, while the upper and lower ends on the other side are slidably fitted onto the connecting seat and the base, respectively.

[0012] Furthermore, the cross bracket is driven by a hydraulic system, which includes a hydraulic rod and a drive pump. The hydraulic rod is mounted on the cross bracket, and the drive pump is mounted on the base. When the hydraulic rod extends, it drives the connecting seat to rise, and when it shortens, it drives the connecting seat to fall.

[0013] Furthermore, the height of the retractable sunroom roof from the ground is 1.2 to 1.3 times the height of a helicopter, and there is redundant space at the top when it is closed.

[0014] Furthermore, the width of the retractable sunroom is 1 to 1.2 times the diameter of the helicopter landing platform, and the length of the lifting opening formed after the retractable sunrooms on both sides are unfolded is 1 to 1.2 times the diameter of the helicopter landing platform.

[0015] This utility model has the following advantages and beneficial effects:

[0016] The design employs a symmetrical retractable sunroom structure in conjunction with a lifting platform. By elevating the helicopter rotor to 1.2-1.3 times its height above the sunroom's top, it effectively avoids the aerodynamic resonance issues of traditional hangars under strong winds. Combined with three sets of hydraulic lifting mechanisms arranged in an equilateral triangle, it ensures the platform's lifting stability meets building wind resistance standards. The disc-shaped landing platform's diameter is optimized to 2-2.5 times the propeller diameter, and with its ground-embedded mounting groove design, the equipment is flush with the ground when fully retracted. This maximizes the utilization of high-rise space while creating a safe area that conforms to the aerodynamic characteristics of helicopter takeoff and landing through a sunroom deployment spacing of 1-1.2 times the platform diameter.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0031] like Figures 1 to 10As shown, this embodiment discloses a retractable mobile hangar, installed on a rooftop, comprising two symmetrically installed retractable sunrooms 1 and a helicopter landing platform 2. When the two sets of retractable sunrooms 1 are closed together, they cover the helicopter on the helicopter landing platform 2, forming a shield. When the two sets of retractable sunrooms 1 are extended to the sides, they form an elevator opening 3 in the middle for helicopter take-off and landing. The size of the retractable sunrooms 1 and the helicopter landing platform 2 is designed according to the size of the helicopter. Specifically, the helicopter landing platform 2 is a disc-shaped structure with a diameter 2-2.5 times the diameter of the helicopter rotor, while the width of the retractable sunrooms 1 is 1-1.2 times the diameter of the helicopter landing platform 2. The length of the elevator opening 3 formed by the retractable sunrooms 1 on both sides after being extended is 1-1.2 times the diameter of the helicopter landing platform 2. In addition, the height of the roof of the retractable sunroom 1 from the ground is 1.2-1.3 times the height of the helicopter, so that there is still sufficient redundant space at the top when the two retractable sunrooms 1 are closed.

[0032] Furthermore, each set of retractable sunrooms 1 includes two parallel slide rails 11 fixed to the ground on both sides of the helicopter landing platform 2, three identical frame units 12 slidably fitted onto the slide rails 11, and a drive mechanism 13 installed between the three frame units 12. The drive mechanism 13 drives the frame units 12 to move along the slide rails 11. Specifically, the height and width of the three frame units 12 increase proportionally. Correspondingly, the slide rails 11 are provided with three parallel grooves 110. The three sets of frame units 12 slide in the grooves 110 on the inner, middle, and outer sides of the slide rails 11 in a proportional manner from smallest to largest. Thus, each frame unit 12... Each frame unit 12 can slide independently in its corresponding groove 110 without interfering with each other. When the lifting port 3 is fully extended, the three frame units 12 are stacked like scales. In addition, when the lifting port 3 is closed, the gaps between the stacked parts of the three sets of frame units 12 are sealed by sealing strips to prevent rainwater from flowing into the interior. Furthermore, there are tenon and mortise structures 120 between the frame units 12 that are closed on both sides. After the tenon and mortise structures 120 are engaged, they are also sealed by sealing strips. Preferably, the tenon and mortise structures are stepped tenons and mortise structures. On the frame units 12 that are closed on both sides, staggered protrusions are provided along the closing edge. After the frame units 12 are closed, they are sealed by the abutting of the staggered protrusions.

[0033] Furthermore, the frame unit 12 includes a top frame 121 and a support frame 122 connected to both sides of the top frame 121 and forming a support. Viewed from the side, the top frame 121 protrudes upwards to form an arched structure. The top frame 121 consists of multiple main beams 1211 with arc-shaped structures, multiple connecting rods 1212, and multiple protective panels 1213. The main beams 1211 are arranged in parallel, the connecting rods 1212 connect adjacent main beams 1211, and the protective panels 1213 are fixed between adjacent main beams 1211 and cover the connecting rods 1212. Additionally, the support frame 122 consists of multiple vertically arranged support rods 1221, multiple horizontally arranged connecting rods 1212, and multiple protective panels 1213. The support rods 1221 are arranged corresponding to the main beam 1211. Multiple connecting rods 1212 are horizontally connected between two adjacent support rods 1221. Multiple protective panels 1213 are connected between two support rods 1221 and cover the connecting rods 1212. Since the bottom of the support frame 122 also needs to cooperate with the slide rail 11, a connecting plate 1222 is also provided at the bottom of the support frame 122. The bottom ends of the multiple support rods 1221 are fixedly connected to the connecting plate 1222 by bolts or welding. The support frame 122 cooperates with the slide rail 11 through the connecting plate 1222. Preferably, the protective panel 1213 is made of fully transparent or semi-transparent sun-proof glass. The two sides of the protective panel 1213 are connected to the main beam 1211 or the support rod 1221 by glass glue.

[0034] Furthermore, to make the frame unit 12 slide more smoothly on the slide rail 11, each groove 110 on the slide rail 11 is provided with multiple pulley sets 14. Each pulley set 14 includes a connecting block 141, support blocks 142 disposed on both sides of the bottom of the connecting block 141, and multiple rollers 143 rotatably mounted between the support blocks 142 on both sides via a rotating shaft. The pulley set 14 is fixed to the bottom of the connecting plate 1222 by the connecting block 141. To prevent the pulley set 14 from detaching... The track is provided with limiting grooves 1420 on the support blocks 142 on both sides, and limiting edges 1101 extend inward from both sides of the groove opening of the slide groove 110. When the pulley group 14 enters the slide groove 110 from the end of the slide rail 11, the limiting edges 1101 on both sides of the groove opening slide into the limiting groove 1420 for vertical limiting. By limiting the pulley group 14 through the limiting edges 1101, derailment can be prevented and the stability of the telescopic sunroom 1 can be guaranteed, thus enabling it to cope with strong winds.

[0035] In this embodiment, since the three frame units 12 slide independently in different slide rails 110, multiple sets of drive mechanisms 13 are needed to drive the frame units 12 to move when opening or closing the lifting port 3. To save resources, the inner frame unit 12 is fixed to the slide rail 11, and the drive mechanism 13 is installed on the middle frame unit 12, specifically on the bottom of the support frame 122 on the frame unit 12. The drive mechanism 13 includes synchronous pulleys 131 fixedly installed at the front and rear ends of the support frame 122, a synchronous belt 132 sleeved on the synchronous pulleys 131 at both ends, and a drive motor 133 installed at one end of the support frame 122. The drive motor 133 is connected to one of the synchronous pulleys 131 and drives the synchronous belt 132 to rotate through the synchronous pulley 131. In addition, the support frame 122 on the inner frame unit 12 is also provided with a first synchronous block 134. The first synchronous block 134 is fixed on the support frame 122 near the lifting port 3 and facing the center. The frame unit 12 has a first synchronization block 134 fixedly connected to a synchronization belt 132. A second synchronization block 135 is also provided on the support frame 122 located on the outer frame unit 12. The second synchronization block 135 is fixed on the support frame 122 at the end away from the lifting port 3 and facing the middle frame unit 12. That is, the first synchronization block 134 and the second synchronization block 135 are respectively connected to both sides of the synchronization belt 132. When the drive motor 133 drives the synchronization belt 132 to rotate, the synchronization belt 132 drives the middle frame unit 12 to move along the slide groove 110 through the reverse force acting on the first synchronization belt 132. At the same time, the synchronization belt 132 drives the outer frame unit 12 to move along the slide groove 110 through the second synchronization block 135. It should be noted that the moving speed of the outer frame unit 12 is twice that of the middle frame unit 12. In this way, only one set of drive mechanism 13 is needed to drive the two frame units 12 to move synchronously at the same time, which not only reduces the cost, but also improves the unfolding or closing speed.

[0036] In this embodiment, to facilitate helicopter takeoff and landing, the helicopter landing platform 2 needs to be raised to a certain height so that the helicopter rotor is level with or above the roof of the retractable sunroom 1. Therefore, a lifting mechanism 4 needs to be installed at the bottom of the helicopter landing platform 2. Specifically, a circular mounting groove 30 is opened on the ground, and the bottom of the mounting groove 30 is connected to the drainage system. The diameter of the mounting groove 30 is larger than the diameter of the helicopter landing platform 2. The lifting mechanism 4 is fixed in the mounting groove 30, and the helicopter landing platform 2 is installed on top of the lifting mechanism 4. When the lifting mechanism 4 is lowered to its lowest position, the top plane of the helicopter landing platform 2 is level with the ground. Preferably, to ensure stability during lifting, the lifting mechanism 4 is provided in three sets, and the three sets of lifting mechanisms 4 are distributed in an equilateral triangle.

[0037] Specifically, the lifting mechanism 4 includes a base 41, a cross bracket 42 movably mounted on the base 41, and a connecting seat 43 mounted on the top of the cross bracket 42. The cross bracket 42 has four ends. The upper and lower ends on the same side are rotatably connected to the connecting seat 43 and the base 41, respectively, while the upper and lower ends on the other side are slidably fitted onto the connecting seat 43 and the base 41, respectively. The cross bracket 42 is driven by a hydraulic system, which includes a hydraulic rod 44 and a drive pump 45. The hydraulic rod 44 is mounted on the cross bracket 42, and the drive pump 45 is mounted on the base 41. When the hydraulic rod 44 extends, the cross bracket 42 drives the connecting seat 43 to rise, and when it shortens, it drives the connecting seat 43 to fall.

[0038] In this embodiment, the retractable sunroom 1 is also provided with a side window 15 and a side door 16 on the side away from the lifting port 3, and also includes a crossbeam 123 connected to the top of the two side support frames 122. The side window 15 is installed on the upper side of the crossbeam 123, and the side door 16 is installed on the lower side of the crossbeam 123. The side door 16 can be opened, while the side window 15 cannot be opened. Therefore, a fan 17 is also provided on the side window 15. When the helicopter takes off, it forms an obstruction at the side window 15 position, which causes the interior of each sunroom to be affected by strong airflow. Moreover, the airflow circulating inside the sunroom can also easily affect the normal take-off of the helicopter. The fan 17 can exhaust the airflow from the inside, thereby avoiding turbulence.

[0039] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
