OBJECT DISPLACEMENT METHOD Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in devices for providing displacement of objects, bringing objects, including those of large size and mass, out of aircraft, ejection, load-handling operations and pushing submersible projectiles out of shift launchers. Chamber with step-by-step changing of volume is formed on base of flexible hose laid in ordered fashion by means of closed guide with bottom and pusher proper. Compact ordered laying of flexible hose is provided using the following procedure: flexible hose unfolded in length and perimeter is divided into steps, and locks 6 are installed inside and outside each step. Then hose is folded on each step over perimeter in form of member-fold with top and two bases. Members folds are shifted towards each other tightly to form S-turn member 13. Each member-fold of S-turn members 13 is tilted by bases in direction from front edge 2 to terminal edge of hose, members-folds are fixed by tops in succession, and bases are fixed on each member-fold to each other and in position of tilted S-turn member 13. Chamber of step-by-step changeable volume is formed as follows: front edge is connected with rigid pusher 17, and terminal edge of hose is connected with closed guide 20 provided with bottom 21 to form chamber 22. Object is displaced by building pressure in chamber 22 by moving pusher 17 under action of which tops of neighbor tilted members-folds are released in step-by-step succession, and bases are released and members-folds are moved aparts step-by-step with simultaneously sealing of following tilted member-fold, thus providing step-by-step unfolding of hose in step-by-step changing volume of chamber 22. Invention provides regulated conditions of object displacement process at preset efforts and velocity in enlarged control range and curvilinear displacement of pusher with object.

EFFECT: improved safety, failure proofness and reliability, increased service life.
