Description

Technical Field

[0001] This utility model relates to the field of helipad technology, and in particular to a prefabricated anti-slip helipad. Background Technology

[0002] An apron is an important infrastructure for the parking, maintenance, and takeoff and landing of aircraft.

[0003] Traditional helipads are mostly constructed using methods such as monolithic casting or on-site welding. These methods have many drawbacks. Monolithic casting helipads have long construction cycles, and if problems arise during construction, rectification and repair are very difficult, which can seriously affect the project schedule. Moreover, traditional helipads have poor mobility and reusability. When the parking location needs to be relocated or modified, these helipads often cannot be reused, resulting in a waste of resources. In addition, in some special environments, such as mountainous areas, islands, and other areas with complex terrain, the construction of traditional helipads is even more difficult. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a prefabricated anti-slip parking apron.

[0005] The technical solution of this utility model is a prefabricated anti-slip parking apron, which includes a frustum, multiple sets of ring bracket assemblies, multiple sets of support assemblies and multiple sets of ring platform assemblies. The truncated cone is located at the center of the annular support assembly; the annular support assembly includes multiple arc-shaped plates; the support assembly includes a support plate, legs, threaded columns, and a buffer pad, wherein the legs are connected to the ends of the support plates, and the legs have threaded grooves that are threaded to the threaded columns; the buffer pad is located at the bottom of the threaded columns; the bottom of the truncated cone and multiple arc-shaped plates are all connected to bolts, and the bolts are threaded with wing nuts; multiple support plates have multiple through holes for the bolts to pass through; multiple annular truncated cones each include multiple sector plates, and the bottom of each sector plate is symmetrically connected to two L-shaped rods; the inner and outer sides of the multiple annular support assemblies in the middle, the outer periphery of the truncated cone, and the inner side of the outermost arc-shaped plate all have notches for the L-shaped rods to pass through.

[0006] Preferably, one end of the arc-shaped plate is connected to a limiting block, and the other end of the arc-shaped plate is provided with a slot for the limiting block to be engaged.

[0007] Preferably, each of the L-shaped rods at the bottom of any one of the fan-shaped plates on each annular platform assembly is threaded with a hand-tightening screw, and positioning grooves are provided on the inner sidewalls of multiple annular support assemblies.

[0008] Preferably, a circular plate is provided at the upper end of the frustum.

[0009] Preferably, the upper end of the bolt is provided with a bolt head, and the thickness of the bolt head is greater than the thickness of the bottom horizontal plate of the L-shaped rod.

[0010] Preferably, the upper ends of multiple sector plates are provided with anti-slip pads.

[0011] Preferably, multiple sets of annular support assemblies and multiple sets of annular platform assemblies are coaxially arranged, and the fan-shaped plates on different sets of annular platform assemblies are of different sizes, and multiple sets of support assemblies are distributed along the annular array.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The device adopts a modular design, which allows each component to be prefabricated in the factory and only requires simple assembly during on-site installation. When installing the ring platform component, the operator does not need to move the position. He only needs to align the L-shaped rod at the bottom of the sector plate with the notch, insert it and rotate it to complete the installation. When installing the next sector plate, he only needs to rotate the previous sector plate to another position. This allows for the installation of multiple sector plates in the same position, which greatly improves the installation efficiency of the device. 2. When the platform is set on uneven ground, the support height of the corresponding side support components can be precisely controlled by rotating the threaded column, which can effectively compensate for the undulations and potholes of the ground, ensure that the plane above the equipment is in a level state, and improve the applicability of the helipad.

[0015] Example 1; as Figures 1-5 As shown in the figure, the prefabricated anti-slip parking apron proposed in this embodiment includes a frustum 1, multiple sets of annular bracket assemblies, multiple sets of support assemblies, and multiple sets of annular platform assemblies; The truncated cone 1 is located at the center of the ring support assembly. A circular plate 101 is provided at the upper end of the truncated cone 1. The circular plate 101 installed on the top of the central truncated cone 1 serves as an independent cover plate to fill the gap in the center position, further enhancing the structural integrity of the central area and improving the overall aesthetics.

[0016] The ring-shaped support assembly includes multiple arc-shaped plates 2.

[0017] Multiple sets of support components are distributed along a ring array; the support components include support plates 4, legs 5, threaded columns 6, and buffer pads 7, wherein the legs 5 are connected to the ends of the support plates 4, and the legs 5 have threaded grooves that are threaded to the threaded columns 6. The buffer pads 7 are located at the bottom of the threaded columns 6. The bottom ends of the frustum 1 and multiple arc plates 2 are all connected to bolts 10, and wing nuts 11 are threaded onto the bolts 10. Multiple support plates 4 have multiple through holes 401 for the bolts 10 to pass through.

[0018] Multiple sets of annular support assemblies and multiple sets of annular platform assemblies are coaxially arranged. Each annular platform includes multiple sector plates 3. The size of the sector plates 3 varies in different annular platform assemblies. Anti-slip pads are provided on the upper ends of multiple sector plates 3. An anti-slip pad is laid on the upper surface of all sector plates 3. This padding material not only increases the friction of the aircraft landing gear but also assists in the smooth landing and parking of the aircraft. Two L-shaped rods 8 are symmetrically connected to the bottom of each sector plate 3. It is worth noting that the upper end of the bolt 10 is provided with a bolt head, and the bolt head... The thickness is greater than the thickness of the bottom horizontal plate of the L-shaped rod 8. The above structure design ensures that when the sector plate 3 is installed, the horizontal plate of its L-shaped rod 8 will not contact the arc plate 2 during rotation, thus avoiding interference. The inner and outer sides of the multiple ring bracket assemblies in the middle, the outer periphery of the frustum 1, and the inner side of the outermost arc plate 2 are all provided with notches 202 for the L-shaped rod 8 to pass through. Each sector plate 3 on each ring platform assembly has a hand screw 12 threadedly connected to the bottom L-shaped rod 8. The inner sidewalls of the multiple ring bracket assemblies are all provided with positioning grooves 203.

[0019] The working principle of this technical solution is as follows: When the platform is set on uneven ground, the operator can adjust each individual support point. By rotating the threaded column 6, the support height of the corresponding side support component can be precisely controlled, which can effectively compensate for the undulations and potholes of the ground and ensure that the upper plane of the equipment is in a level state. The buffer pad 7 installed at the bottom of the threaded column 6 can generate a large static friction force, thereby preventing the support position from slipping on the ground. Furthermore, when subjected to aircraft impact loads, the buffer pad 7 can absorb energy and buffer by undergoing slight deformation, thereby greatly improving the stability of the entire platform.

[0020] After leveling the device, the operator begins assembling the load-bearing frame of the platform. The frustum 1 and the assembled ring bracket assembly are inverted so that the bolts 10 at the bottom of the frustum 1 pass through the holes 401 on the corresponding support plate 4 and are tightened from below by the wing nuts 11. Following the same method, the bolts 10 connected to the arc plate 2 also pass through the corresponding holes 401 on the support plate 4 and are then locked by the wing nuts to firmly connect the arc plate 2 and the support plate 4, thus completing the connection of the load-bearing frame. It should be noted that multiple bolts 10 are provided at the bottom of the frustum 1.

[0021] After the load-bearing frame is erected, the annular platform assembly that directly contacts the aircraft needs to be laid. Each ring of the platform consists of multiple sector plates 3, and the bottom of each sector plate 3 is connected to two L-shaped rods 8. Notches 202 for inserting these L-shaped rods 8 are provided on the annular frame (including the outer perimeter of the frustum 1, the inner and outer sides of the middle arc plate 2, and the inner side of the outermost arc plate 2). During installation, the operator does not need to move the position; they simply align the two L-shaped rods 8 at the bottom of a sector plate 3 with the corresponding notches 202 on the inner and outer sides of the ring and place it vertically. Then, the sector plate 3 is rotated horizontally so that the horizontal arm of the L-shaped rod 8 slides from the notch 202 to the other side. At this point, the sector plate 3 is limited by the L-shaped rod 8 and cannot detach upwards. Then, all the sector plates 3 in the same ring are installed sequentially on the same side using a similar method. It is worth noting that after the last sector plate 3 is placed, the entire annular platform assembly forms a complete ring. In order to prevent the annular platform assembly from rotating under external force, after all the sector plates 3 are installed, the entire annular assembly is slightly rotated until the end of the hand screw 12 is aligned with the positioning groove 203 on the inner wall of the corresponding arc plate 2. Then, the hand screw 12 is tightened by hand so that its tip is screwed into the positioning groove 203. This completes the firm locking of all sector plates 3 and prevents any possible relative rotation.

[0022] Example 2; as Figure 5 As shown in the figure, the prefabricated anti-slip parking apron proposed in this embodiment has a limit block 9 connected to one end of the arc plate 2, and a slot 201 for the limit block 9 to be inserted into the other end of the arc plate 2.

[0023] In this embodiment, when assembling multiple sets of ring bracket components, when two arc plates 2 are joined together, the limiting block 9 on one arc plate 2 slides into the slot 201 of the adjacent arc plate 2. The above structure can effectively prevent misalignment or height difference at the splicing point, and ensure the roundness and integrity of the ring frame.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
