Abstract
The invention discloses an aluminum alloy helicopter platform. The aluminum alloy helicopter platform comprises a bottom frame and a plurality of deck plates, wherein the plurality of deck plates are spliced integrally and are fixed on the bottom frame; the deck plates 2 are made of aluminum alloy profiles and comprise an upper top plate 20 and a lower bottom plate 21; a hollow cavity with rib plates is formed between the upper top plate and the lower bottom plate; the upper top plate has a matchboard structure; and connection parts for fixing the deck plates on the bottom frame extend out of the two sides of the lower bottom plate. The aluminum alloy helicopter platform adopts the deck plates made of the aluminum alloy profiles, a characteristic that the aluminum alloy specific gravity is small is utilized, and the anti-bending strength of the profiles is fully utilized, so that the self-weight is greatly reduced; and meanwhile, the deck plates are spliced through rabbets and are fixed on the bottom frame by virtue of pressing plates or bolts, so that the aluminum alloy helicopter platform is convenient to mount; and moreover, proper aluminum alloy materials are adopted and do not need to be painted for maintaining in the service life period.

Summary of the invention
The object of the present invention is to provide a kind of aluminium alloys helicopter platform, it has in light weight, easy for installation and safeguards characteristic of simple, to solve the problem that helicopter platform exists in the prior art.
For reaching this purpose, the present invention by the following technical solutions:
A kind of aluminium alloys helicopter platform, it comprises underframe and is fixed on the underframe several and splices all-in-one-piece deck piece mutually, described deck piece adopts aluminium alloy extrusions, it comprises upper plate and lower shoe, be provided with the sheet with rib cavity between described upper plate and the lower shoe, described upper plate is the matched boards structure, and the both sides of described lower shoe all are extended with for the connecting portion that the deck piece is fixed on the underframe.
Especially, described underframe is any of steel or aluminum alloy material.
Especially, described upper plate, lower shoe and sheet with rib cavity adopt integrated formed structure.
Especially, described sheet with rib cavity comprises the some gripper shoes that tilt or vertically arrange that are connected at interval between upper plate and the lower shoe.
Especially, correspondence offers through hole on described connecting portion and the underframe, and set bolt passes both through holes and with nut check the deck piece is fixed on the underframe.
Especially, described deck piece is fixed on the underframe by upper and lower pressing plate, and the dual-side of described connecting portion has extended upward lug boss, and an end of described lower platen is withheld on underframe, the other end is withheld in the bottom of lower shoe or top board, by hold-down nut the deck piece is fixed on the underframe.
Especially, the upper surface of described upper plate is provided with many antislip cogs, can process the profile of tooth breach along the fin direction, increases frictional force.
Especially, connect in the tongue and groove of adjacent two deck pieces and be provided with weather strip, and the junction of the upper surface of adjacent two deck pieces seals by fluid sealant.
Beneficial effect of the present invention is that compared with prior art described aluminium alloys helicopter platform adopts the deck piece of being made by aluminium alloy extrusions, utilizes the characteristics of aluminium alloys light specific gravity, and takes full advantage of the flexural strength of section bar, has alleviated deadweight greatly.Simultaneously, by the tongue and groove splicing, the deck is adopted pressing plate or is bolted on the underframe, and is easy for installation between the piece of deck.And, adopt maintenances such as suitable aluminum alloy material does not need to paint in the cycle in application life.
