Description

Technical Field

[0001] This utility model belongs to the technical field of safety nets for helipads, specifically, it relates to a flipping mechanism for a protective net used on vertical take-off and landing helipads. Background Technology

[0002] Cities have long needed helicopters. With rapid economic development and the continuous improvement of people's living standards, helicopters are gradually being used more and more widely in people's daily lives, especially in medical rescue, highway rescue, high-rise fire fighting, and air tourism.

[0003] When helicopters land on the helipad, they need to be surrounded and protected by protective nets. Under current technology, aluminum protective nets are mostly used. Aluminum protective nets are not only lightweight, but can also withstand the force of a 180kg object falling freely from a height of 1.1 meters, thus improving the safety of the helipad.

[0004] However, the following problems have been exposed in practical applications: First, the protective netting relies on a single power source or rigid connection for its flipping process, making the unfolding and retraction movements inflexible and unable to adapt to the needs of rapid deployment or emergency closure under different weather conditions; Second, the protective netting support structure lacks stability, and the load of the helipad itself, the impact of aircraft take-off and landing, or external wind forces can easily cause deformation of the protective frame, or even cause hinge breakage and other malfunctions; Third, after the protective netting is flipped to a horizontal state, it lacks a precise positioning device, and is prone to displacement due to vibration or accidental collisions, making it impossible to reliably fix the position of the protective netting; Fourth, in complex building environments, the protective netting needs to adjust its flipping angle according to the relative position of the helipad and the main building, and traditional structures are unable to achieve multi-dimensional flexible support.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a protective net flipping mechanism for vertical take-off and landing aprons, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A protective netting flipping mechanism for a vertical take-off and landing helipad includes: a main building, a helipad, and a protective frame. The helipad is fixedly installed on one side of the main building. The bottom end of the protective frame is rotatably connected to one side of the helipad via a hinge. A protective netting is fixedly installed inside the protective frame. A crossbeam is provided on one side surface of the protective netting. The end of the crossbeam is fixedly connected to the inner wall of the protective frame. Two support beams are fixedly installed on one side of the bottom of the main building. A connecting beam is fixedly connected between the ends of the two support beams. A hinge block one is fixedly connected to the side of the connecting beam. An electric push rod is rotatably connected to the hinge block one. A second hinge block is fixedly connected to the side of the crossbeam. The top end of the electric push rod is rotatably connected to the second hinge block.

[0008] Optionally, a reinforcing support column is fixedly connected to the top of the middle part of the support beam, and the top of the reinforcing support column is fixedly connected to the lower surface of the helipad.

[0009] Optionally, a diagonal brace is fixedly connected to the top end of the support beam near the end of the support beam. The top end of the diagonal brace is fixedly connected to the side of the reinforcing support column, and the reinforcing support column, the diagonal brace, and the support beam form a triangle.

[0010] Optionally, a bottom support block is fixedly connected to the bottom edge of the protective frame. The bottom support block is perpendicular to the side of the protective frame, and a reinforcing rib is provided between the side of the bottom support block and the side of the protective frame.

[0011] Optionally, a second base support block is fixedly connected to the bottom of the helipad near the protective frame. Two guide rods are slidably inserted into the surface of the second base support block. One end of each guide rod is fixedly connected to an abutment plate, which corresponds to the position of the first base support block. An adjusting threaded rod is rotatably connected to the surface of the abutment plate where the guide rod is located, and the adjusting threaded rod is threadedly connected to the second base support block.

[0012] Optionally, both sides of the protective frame are provided with sliding grooves, and a locking block is slidably engaged inside the sliding groove. A rotating support frame is rotatably connected to the side of the locking block. A hinge block three is fixedly connected to the upper surface of the helipad, and the bottom end of the rotating support frame is rotatably connected to the hinge block three.

[0013] Optionally, the groove wall of the slide is provided with a through groove that extends to the surface of the protective frame, and a fastening bolt is threaded into the side of the locking block, the fastening bolt being slidably engaged with the through groove.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: The protective frame is hinged to the helipad at its bottom, and connected to it via an electric push rod through hinge blocks one and two, providing flexible power for the rotation and retraction of the protective net. A reinforced support column in the middle of the support beam is fixed to the lower surface of the helipad to distribute the load and prevent deformation. Its end diagonal brace, along with the reinforced support column and support beam, forms a triangular structure to further enhance stability. Bottom support block one at the bottom of the protective frame is vertically positioned, providing a stable support surface when rotated to a horizontal position and, with reinforcing ribs, increasing its strength to prevent collision damage. Bottom support block two at the bottom of the helipad is guided by a guide rod... The sliding guide plate, combined with the position adjustment of the threaded rod, can precisely fit the bottom support block to position the protective frame horizontally. The locking blocks in the sliding grooves on both sides of the protective frame can slide along the grooves and are rotatably connected to the helipad hinge block through the rotating support frame. This disperses the load during the flipping process and reduces the risk of wear on a single hinge. The through groove wall, together with the fastening bolts on the side of the locking block, can lock the position after the locking block is adjusted to ensure accurate and reliable support of the rotating support frame. The overall structure takes into account flexibility, stability and durability, effectively meeting the requirements for rapid deployment and reliable fixation of the vertical take-off and landing helipad protective net.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Please see Figure 1-3 As shown, this embodiment provides a protective net flipping mechanism for a vertical take-off and landing helipad, including: a building body 100, a helipad 200, and a protective frame 300. The helipad 200 is fixedly installed on one side of the building body 100. The bottom end of the protective frame 300 is rotatably connected to one side of the helipad 200 via a hinge. A protective net 301 is fixedly installed inside the protective frame 300. A crossbeam 302 is provided on one side surface of the protective net 301. The end of the crossbeam 302 is fixedly connected to the inner wall of the protective frame 300. Two support beams 202 are fixedly installed on one side of the bottom of the building body 100. A connecting beam 205 is fixedly connected between the ends of the two support beams 202. A hinge block 1 204 is fixedly connected to the side of the connecting beam 205. An electric push rod 600 is rotatably connected to the hinge block 1 204. A hinge block 2 303 is fixedly connected to the side of the crossbeam 302. The top end of the electric push rod 600 is rotatably connected to the hinge block 2 303.

[0021] The protective frame 300 is hinged to one side of the helipad 200, allowing for easy flipping and retraction of the protective netting 301. The electric push rod 600 is rotatably connected to the support beam 202 via hinge block 1 204 and to hinge block 2 303 on the side of the crossbeam 302 at its top, providing stable power support for the flipping of the protective frame 300. The overall structure is compact and flexible in operation, meeting the needs of vertical take-off and landing helipads for rapid deployment or storage of the protective netting.

[0022] To share the load pressure borne by the support beam 202, its specific structure is as follows: Figure 1-2 As shown, a reinforcing support column 201 is fixedly connected to the top of the middle section of the support beam 202, and the top of the reinforcing support column 201 is fixedly connected to the lower surface of the helipad 200. By fixing the top of the reinforcing support column 201 to the lower surface of the helipad 200, the load pressure borne by the support beam 202 can be effectively distributed, avoiding deformation or breakage of the support beam 202 due to long-term stress or accidental impact, and improving the structural reliability of the connection between the helipad 200 and the support beam 202.

[0023] To ensure the stability of the parking apron 200 when subjected to aircraft takeoff and landing loads or external wind forces, its specific structure is as follows: Figure 1-2As shown, a diagonal brace 203 is fixedly connected to the top end of the support beam 202 near the hinge block 204. The top end of the diagonal brace 203 is fixedly connected to the side of the reinforcing support column 201, forming a triangle with the reinforcing support column 201, the diagonal brace 203, and the support beam 202. The fixed connection between the top end of the diagonal brace 203 and the side of the reinforcing support column 201, together with the reinforcing support column 201 and the support beam 202, forms a stable triangular structure. The geometric properties of the triangle further enhance the shear resistance and overturning resistance of the support system.

[0024] To extend its service life, its specific structure is as follows: Figure 3 As shown, a bottom support block 306 is fixedly connected to the bottom edge of the protective frame 300. The bottom support block 306 is vertically positioned relative to the side of the protective frame 300, and a reinforcing rib is provided between the side of the bottom support block 306 and the side of the protective frame 300. By vertically positioning the bottom support block 306 on the side of the protective frame 300, a stable supporting contact surface is provided at the bottom of the protective frame 300 when it is flipped downwards to a horizontal position, preventing the protective frame 300 from directly colliding and being damaged by the apron 200 or other structures. The reinforcing rib between the bottom support block 306 and the side of the protective frame 300 enhances the structural strength of the bottom support block 306 itself.

[0025] To improve the stability of the protective net 301 after it is deployed, its specific structure is as follows: Figure 1-3 As shown, a second base support block 500 is fixedly connected to the bottom of the helipad 200 near the protective frame 300. Two guide rods 502 are slidably inserted into the surface of the second base support block 500. One end of each guide rod 502 is fixedly connected to an abutment plate 501, which corresponds to the position of the first base support block 306. An adjusting threaded rod 503 is rotatably connected to the surface of the abutment plate 501 where the guide rods 502 are located. The adjusting threaded rod 503 is threadedly connected to the second base support block 500. The guide rods 502 on the surface of the second base support block 500 guide the abutment plate 501 to slide in a straight line. By adjusting the threaded engagement between the adjusting threaded rod 503 and the second base support block 500, the position of the abutment plate 501 is adjusted, ensuring that the abutment plate 501 fits tightly against the first base support block 306 at the bottom of the protective frame 300. This achieves precise positioning and auxiliary fixation of the protective frame 300 in a horizontal state after it is flipped over.

[0026] To avoid wear or failure caused by excessive force on a single hinge connection, its specific structure is as follows: Figure 1-3As shown, both sides of the protective frame 300 are provided with sliding grooves 304. A locking block 402 is slidably engaged inside the sliding groove 304. A rotating support frame 401 is rotatably connected to the side of the locking block 402. A hinge block 300 is fixedly connected to the upper surface of the helipad 200. The bottom end of the rotating support frame 401 is rotatably connected to the hinge block 300. The locking block 402, slidably engaged inside the sliding groove 304, can be adjusted in position along the sliding groove 304. Combined with the rotatable connection between the rotating support frame 401 and the hinge block 300, this provides additional support points during the rotation of the protective frame 300, distributing the rotation load of the protective frame 300.

[0027] To ensure the accurate and reliable support position of the pivot bracket 401, its specific structure is as follows: Figure 1-3 As shown, the groove 304 has a through groove 305 extending to the surface of the protective frame 300. A fastening bolt 403 is threaded into the side of the locking block 402, and the fastening bolt 403 is slidably engaged with the through groove 305. The design of the through groove 305 extending to the surface of the protective frame 300 allows the fastening bolt 403 on the side of the locking block 402 to slide and lock along the through groove 305. When the locking block 402 is adjusted to a suitable position, it is fixed by the engagement of the fastening bolt 403 with the through groove 305, preventing the locking block 402 from accidentally sliding during the rotation of the protective frame 300 or during use.
