The invention discloses a kind of expandable type truss structure locking device and its application method, including deployable trusses, locking device and steel wire rope；Locking device bottom is consolidated by two steel wire ropes with deployable trusses, so as to realize the positioning of locking device, locking device top is assembled together by pulley and steel wire rope, and the steel wire rope both ends all connect deployable trusses, so as to realize that locking device links together with truss.Locking device top steel wire rope determines that opening position is fixed with a small steel ball, steel wire penetrating driver plate aperture corresponding with baffle plate, when truss is deployed into specified location, small steel ball passes through baffle plate from right-hand apron, reach at right-hand apron aperture, driver plate is stirred, the certain angle so that driver plate and baffle plate stagger, realizes locking function.Expandable type truss structure locking device of the present invention effectively can easily realize the locked conversion between folded state, and be easy to processing to be easily assembled, and be a kind of simple and easy deployable trusses locking device.
Description
Technical field
The present invention relates to a kind of locking device and its application method of expandable type truss structure, and in particular to one kind works as purlin
, can effectively latch-up structure when frame is deployed into designated state.
Background technology
Deployable trusses structure is a kind of new type foldable structural system to grow up in recent years, in Aero-Space, mechanic
Have in journey and daily life and widely apply.The concept of deployable structure is familiar with already for people, such as daily life
Umbrella in work struts storage, and the expansion of folding seat uses the structure type of open-close type with folding and perhaps great stadiums
Etc., with the development of aerospace industry, deployable structure is due to the distinguishing feature with foldable expansion and wide application neck
Domain, the attention of various countries scientific worker is increasingly received, achieve huge development.
For deployable trusses, how to realize locking function is be worthy of consideration the problem of, for this problem, both at home and abroad
Scholar expand substantial amounts of research.At present, the locking device applied on most of deployable trusses, main thought are in locked dress
Put and the flexible and different open-cell material in both ends aperture is installed, during expansion, as the Suo Dingqiu on steel wire rope
When passing through aperture, because upstream end aperture is big and material is flexible, it can be very good to squeeze through, but when locking ball is wanted
When returning in situ because return terminal aperture is smaller, lead to not it is return, so as to realize locking function.But this locking device,
Although locking function can be realized well, locking state can not be released, so as to reclaim deployable trusses or folding for the later stage
Folded deployable trusses add difficulty.
For deployable trusses, realize that locked and folded state conversion is essential.
