Description

[0001] HELDECK HAVING ELEVATING MEANS [0002]

The present invention relates to a helideck provided with elevating means.

Generally, rooftops of offshore plants such as drill ship, FPSO (Floating, Production, Storage and Offloading) or buildings (eg high rise building) are used for helicopter (Helicopter) requires the installation of Helideck for takeoff and landing.

The helideck may be comprised of a pancake portion forming a deck floor or take-off landing area where the helicopter takes off and land, and a pancake support portion supporting the pancake portion. The pancake part may be formed by connecting a plurality of plank to each other so as to support the helicopter. The pancake support may include H-shaped beams capable of supporting the pancake portion.

For example, the pancake portion may be formed by connecting a plurality of flank of aluminum material extending in one direction. Further, the pancake supporting portion includes a plurality of aluminum H beams extending long in a direction intersecting the extending direction of the flanks and disposed below the flanks to support the pancake portion, an aluminum H beam extending long in a direction intersecting the extending direction of the aluminum H beam, And a plurality of steel H beams disposed below the beam to support the aluminum H beam.

The heliport, which is a background of the invention, is horizontally installed and has a floor on which the helicopter takes off and land, a support for supporting the floor on which the helicopter is placed, and a hydraulic device or a transmission for vertically lifting the support from the reference surface.

However, according to the conventional heliport, when the helicopter and the floor are lowered by the hydraulic device or the transmission device when the helicopter is lowered to the floor, the floor is lifted up to the upper part where the helicopter is located, And the like can be performed in the vicinity of the reference plane as in the conventional art.

Such prior art helicopters do not disclose any specific means for performing the maintenance of the hydraulic device or the power transmission device or the detailed configuration of the hydraulic device or the power transmission device. Therefore, when a failure occurs in the heliport, I can not cope quickly.

Further, since the prior art heliport has only one strut that lifts the floor upward from the reference plane and there is no means to maintain the raised or lowered state, it is very strong enough to threaten the structure of the heliport When a wind of wind speed (for example, a typhoon) blows into a structure such as a roof of a building, it can not stably support a floor in a structurally raised state.

Also, the prior art helicopter can not move the crew or the cargo to the reference plane until the floor raised by the support is lowered to the reference plane.
