Description

Technical Field

[0001] The utility model relates to the technical field of take-off and landing platforms, in particular to a helicopter take-off and landing platform based on an installation ship. Background Art

[0002] The helipad, as the main activity area for helicopters, plays a vital role. The so-called helipad is a place for helicopters and vertical take-off and landing fighter jets. It is generally required to be equipped with corresponding navigation aids, air traffic control and communication equipment, meteorological facilities, fire and rescue equipment, airport signs, etc., so that it can meet the requirements for safe take-off and landing of helicopters.

[0003] Referring to the Chinese patent, the application number is: "201520086651.7" and is specifically "a helicopter landing pad for offshore operating platforms". This patent solves the problem that "the existing landing pads on drilling platforms or ships have a simple structure, which is provided with a simple supporting truss for supporting the landing deck, but its supporting strength is average, and there is only one exit. When a fire or other accident occurs on the landing pad, it is not only inconvenient to respond to emergencies, but also the supporting truss is easy to collapse";

[0004] In the utility model, the deck's load-bearing capacity is enhanced by supporting the deck with triangular support frames distributed at intervals, and the double-layer panels are used to indirectly enhance the joint strength between the panels, thereby improving the load-bearing capacity of the apron panels and effectively eliminating the resonance generated when the aircraft lands. However, the apron adopts a double-layer panel method, which cannot effectively buffer and shock-absorb the huge impact force acting on the platform at the moment of helicopter take-off and landing. The huge force at the moment of helicopter take-off and landing reacts on the helicopter itself, affecting the service life of its take-off and landing wheel hub frame, and the apron does not have the corresponding slope adjustment capability. When there is a lot of rain, it accumulates on the lifting platform. The horizontal lifting platform does not have good drainage capacity, and the slippery platform surface brings great difficulty and danger to the take-off and landing of the helicopter.
