Pipeline floating connecting device with backing function

Abstract

The invention provides a pipeline floating connecting device with a backing function; the pipeline floating connecting device comprises a backing floating assembly, a backing slide body, a top cover, a ball support, an outer housing, a pressure spring, an extension spring, a torsion spring and a locking lever; the device is fixedly connected with a combined drive mechanism on a service aircraft through the outer housing, and is coupled with a refill-receiving joint arranged on a service-receiving aircraft; when a single motor drives multi-set pipeline floating connecting devices to do pipeline jointing work, and certain set pipeline floating connecting device and the refill-receiving joint cannot complete jointing because of attitude deviation, the jointing between other pipeline floating connecting devices and corresponding refill-receiving joints will not be affected, thus ensuring subsequent high pressure gas-liquid refill and normal break operations; the pipeline floating connecting device is simple in structure, reliable in motions, and can realize fault self-isolation function.

Description

technical field [0001] The invention relates to the technical field of pipeline connection devices for spacecraft, in particular to a pipeline floating connection device with a retreat function. Background technique [0002] With the increasing demand for on-orbit gas-liquid replenishment of spacecraft, it is especially required to overcome the position and attitude deviation of two spacecraft after the rigid docking is completed under the limited load space and weight range, relying on a single motor to drive multiple A set of pipeline floating connection device realizes the connection of multiple sets of gas-liquid pipelines between two aircraft, and then can complete the gas-liquid transmission supplementary operation of tens of MPa in the pipeline; During the pipeline connection process, there is a possibility that one or several supplementary joints are difficult to complete the deviation self-adaptation, and a fault occurs that the joint or joints of the supplementary ...
