TURNING PNEUMOHYDRAULIC UNIT FOR COUPLING MOVING OBJECT WITH MOTIONLESS OBJECT AND METHOD TO OPERATE IT Russian patent published in 2010 - IPC B64G1/22 B64G4/00 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering and can be used for maintenance of inner chamber of assembled object without uncoupling pneumohydraulic lines. Spring assembly for binding mobile unit (22) and fixed unit (24). Proposed unit (22) comprises pipelines with branch pipes (2), bellows (4), adapters to joint bellowed together, clamps (6) etc. Pipelines are connected (in the zone of clamps 6) by links with fasteners. Every link has cheeks to joint links together by two axles fitted in link cheek holes and slots. First three and last two links provide for bellows bending. First and third links accommodate box-like case (17) to protect bent bellows against excess operating pressure. Side walls of said case (17) are attached to third link with the help of screws-axles (18). Straight slots (14) are arranged on case side walls, on opposite side, to receive screws (19). Pipelines bellows arranged between third and penultimate links are clamped by two pins. In operation, links located between said third and penultimate links are released by screwing out aforesaid pins. Then the unit is turned about its last link. Unit is turned back into initial position, pins are fitted in place and locked as required.

EFFECT: ease of maintenance, reduced weight.
