Abstract
The utility model discloses a novel gangway ladder footboard folding mechanism, including gangway ladder door main part with and go up folding footboards at different levels, through footboard gangbar coordinated control between the folding footboards at different levels, every grade folding footboard includes footboard, first bracing piece and second bracing piece, and the side is equallyd divide and do not is provided with first bracing piece and second bracing piece about the footboard, and four -bar linkage is constituteed jointly to first bracing piece, second bracing piece, gangway ladder door main part and footboard, and the section is extended to unified being equipped with outside the pin joint of its first bracing piece or second bracing piece and gangway ladder door main part of folding footboards at different levels, this of folding footboards at different levels extend section respectively with the footboard gangbar is articulated, the footboard has the extension respectively outside its both ends pin joint. The utility model discloses a folding footboard simple structure, and light in weight, the reliability is high, and folding footboards at different levels can link foldingly and the expansion, and the usable space that is favorable to increasing the under -deck increases interior environment's aesthetic property and security.
Description
Technical field
This utility model relates to belonging to aircraft or helicopter gangway ladder door auxiliary machinery field, relates to a kind of novel accommodation ladder platform fold mechanism.
Background technology
Gangway ladder door system is the hatch door of aircraft or helicopter, can be used for again upper and lower occupant and unit in the case of not using ground installation or ladder, passes in and out cabin for occupant, improves aircraft or the globality of helicopter and comfortableness.In the case of various weathers and ground are shut down, gangway ladder door system can safe folding and unfolding, it is simple to occupant and unit boarding or disembark, and has a simple operation, and Stability Analysis of Structures is safe and reliable, succinctly exquisite, saves the features such as space.
It is disclosed as a kind of Foldable pedal disclosed in the Chinese patent literature of CN205010468U, including a planar linkage mechanism collectively constituted by the first support member, the second support member, the 3rd support member, described first support member one end is hinged in gangway ladder door, the other end and second support member one end are hinged, the described second support member other end and the 3rd support member one end are hinged, and the described 3rd support member other end is hinged in gangway ladder door.
Foldable pedal described in above-mentioned patent documentation, has the disadvantage in that the pedal of this Foldable pedal is collectively constituted by the second support member and the 3rd support member, and pedal globality is bad, and reliability is low；Each support member weight is relatively big, reduces aircraft or helicopter load.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, it is provided that a kind of novel accommodation ladder platform fold mechanism, good integrity.
The technical solution adopted in the utility model is such that
nullA kind of novel accommodation ladder platform fold mechanism，Including gangway ladder door main body and Foldable pedal at different levels thereon，By pedal linkage bar coordinated signals between Foldable pedals at different levels，Every grade of described Foldable pedal includes pedal、First support bar and the second support bar，Pedal left and right sides is provided with the first support bar and the second support bar respectively，Bottom described first support bar one end and pedal one end hinged，The other end is hinged with gangway ladder door main body，Bottom described second support bar one end and the pedal other end hinged，The other end is hinged with gangway ladder door main body，Described first support bar、Second support bar、Gangway ladder door main body and pedal are collectively forming quadric chain，What Foldable pedals at different levels were unified in its first support bar or the second support bar pin joint with gangway ladder door main body is externally provided with extension，This extension is hinged with described pedal linkage bar，Described pedal has extension outside its two ends pin joint respectively.
As preferably, described pedal linkage bar is monoblock type, it is also possible to for split type.When pedal linkage bar is split type, to the replacing of Foldable pedal or keep in repair convenient.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: foldable pedal structure is simple, and lightweight, and reliability is high；Under the driving of outside actuating unit, pedal linkage bar drives Foldable pedals at different levels linkage fold and launch, and is conducive to increasing the available space in cabin, increases aesthetic property and the safety of indoor environment.
