Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] The present invention is a docking device for docking pallets with space stations, comprising two parts: a passive end 1 installed on the interface of the space station cabin and an active end 2 installed on the space pallet, such as figure 1 shown.

[0042] The passive end 1 is the load-bearing part of the interface of the space station cabin and has no active movement mechanism. The passive end 1 is a cylindrical structure as a whole, and the end is fixedly installed at the interface of the space station cabin.

[0043]The electrical connectors 101 of the passive end are designed with three equiangular intervals in the inner ring circumferential direction near the central axis of the passive end 1, and are located in the electrical connector notch on the mating surface of the passive end, and are used for connecting with the active end 2. The elect...

Abstract

The invention discloses a berthing device for docking a pallet and a space station. Docking of a driving end and a driven end is realized through cooperating a movable platform lifting control gripperwhich is arranged on the driving end and is driven by a driving mechanism to drive a lead screw to transmit with a groove which is designed in the circumferential direction of the driven end. A guideopening is designed in the gripper along the axis of the gripper and cooperates with a guide pin installed in the top of the groove designed in the circumferential direction of the outer wall of thedriving end to achieve gripper movement guidance. The movable platform is circumferentially positioned through cooperating a groove in a driving end shell with a roller on a circumferential boss of the movable platform. Meanwhile, spring guide rods on the end faces of the driving end and the driven end are designed to be matched with guide positioning holes to realize docking guidance and rapid separation. A manual driving mechanism is further designed to achieve manual control over the gripper. The device has the advantages of stable and reliable connection, simple structure and light weight.

Description

technical field [0001] The invention belongs to the field of space station cargo transportation, in particular to a parking device for docking pallets with a space station. Background technique [0002] With the development of my country's aerospace technology, the establishment and development of the space station is an important integration and embodiment of space technology. In the future, during the orbital flight of my country's space station, it will need the supply of space cargo resources, and it will need to transport ground materials to the space station to realize the docking of space cargo on the space station. [0003] The space cargo will be transported by the cargo spacecraft to the predetermined area of ​​the space, and the pallet system will be pulled out and transferred to the space station by the operation of the space station's mechanical arm, and it will be docked, docked, unlocked and separated from the space station cabin. [0004] The berthing device...
