Description

Technical Field

[0001] The present invention belongs to the technical field of helipads and relates to a multifunctional mobile helipad vehicle frame. Background Art

[0002] The development of cities also promotes the development of transportation. When ground transportation is difficult to meet people's needs, helicopters, as a new type of transportation, are increasingly appearing in people's vision. Traditionally, helicopter pads are generally divided into three types in terms of structure, including concrete structure, steel structure, and aluminum alloy structure. These types of structural forms are mostly used for ground helicopter pads, elevated helicopter pads, ship helicopter pads, and offshore platform helicopter pads. The takeoff and landing of a helicopter require a takeoff and landing platform and can provide ground effect. If there is no suitable landing point, it is difficult for the helicopter to land. Traditional helicopter pads are restricted by economic conditions and geographical environment, so the number of helicopter pads is small, the regional flight of helicopters is limited, and even in some emergency tasks, the task is difficult to complete because the helicopter cannot land. During the use of existing mobile helipads, after deployment, the overall support area and strength are relatively average, making it difficult to handle different light and heavy helicopters according to needs. Moreover, manual operation is required to move the helicopter to a fixed position, resulting in high manual intensity and difficulty.

[0003] In order to overcome the deficiencies of the prior art, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a metal structure helipad [Application No.: 202010735263.2], which includes a support base for support, a deck for parking helicopters, a protective net and a boarding device arranged around the deck. There is a raised building on the building roof layer. The metal structure helipad uses the raised building on the top floor of the building as support. The support base is arranged around the raised building, and the deck is arranged on the raised building and the support base. This application uses the raised building on the top floor of the building as support, and the middle part of the deck is supported by a plane, reducing the pressure of the support force received by the deck and also reducing the point support of the support base, which not only reduces costs but also improves the stability of the helipad. However, after deployment, the overall support area and strength of this solution are still relatively average, making it difficult to handle different light and heavy helicopters according to needs. Moreover, manual operation is required to move the helicopter to a fixed position, resulting in high manual intensity and large difficulty. Summary of the Invention

[0048] The working principle of the present invention is as follows:

[0049] During use, after the extended telescopic platform 2 and the extended helipad main body 3 are unfolded, the abutting fixing seat 4 faces the ground. At this time, the pneumatic support feet 20 are lowered and abutted against the ground through the pneumatic support feet 20 to support the extended telescopic platform 2 and the extended helipad main body 3.

After installation, the platform abutting plate 12 is abutted and matched with the extended telescopic platform 2, and the upper connecting cylinder column 11 and the platform abutting plate 12 are elastically connected through the spring 14, which can ensure that the platform abutting plate 12 and the extended telescopic platform 2 are abutted and kept close. At the same time, it is convenient for installation, and the operation is simple. The auxiliary support bottom plate 18 is driven to descend by the power shaft of the first linear driver 17 to perform multi-directional strengthening support on the gap between the extended telescopic platform 2 and the abutting fixing seat 4, improving the support area and strength. The overall structure is compact, and the detachable structure is adopted, which is convenient for dealing with the landing of heavy helicopters, improving the service life of the extended telescopic platform 2 and the extended helipad main body 3, and the landing effect is good.

[0051] The lightweight hole grooves 15 play a role in reducing the weight of the upper connecting cylinder column 11. When it is necessary to lower the auxiliary support bottom plate 18, the first linear driver 17 is started, and the driving mounting seat 16 and the detachable horizontal fixing support plate 8 are connected by the screw connection plate 19. One end of the screw connection plate 19 is fixedly connected to the driving mounting seat 16, and the other end is connected to the detachable horizontal fixing support plate 8 through fastening bolts. The disassembly and assembly are simple and convenient, which is convenient for the staff to carry out maintenance and replacement.

[0052] After the extended telescopic platform 2 and the extended helipad main body 3 are extended and unfolded, during the landing process of the helicopter, the helicopter is indicated by the landing signal lamp 43, so that the helicopter can land accurately. The embedded structure is adopted to avoid damaging the signal lamp during landing. The diversion cavity groove 42 can guide the airflow during landing to the ground, avoiding excessive air pressure on the surface of the extended helipad main body 3, and improving the service life of the extended helipad main body 3.

[0053] The fixed belt runner 38 is used to connect the fixed belt runner 38. The length of the hook fixing belt 35 can be controlled by a forward and reverse motor to control the body connecting hook 36. After the helicopter lands, first hook and fix the body connecting hook 36 to the helicopter chassis. Then, pull the helicopter between the left fixing seat and the right fixing seat through the body connecting hook 36, eliminating the need for manual pushing and greatly reducing the manual labor intensity. Next, fix the helicopter chassis through the chassis fixing member 32 to prevent the helicopter from sliding during transportation, ensuring better safety.

[0054] When moving the helicopter between the left fixing seat and the right fixing seat, fix the helicopter chassis through the chassis binding belt 40 to prevent the helicopter from sliding during transportation, ensuring better safety. The extendable ladder 41 facilitates the crew to get to the ground.
