Abstract

The invention provides a light and simplified butt-joint locking and releasing device and a working method thereof, and the device comprises a passive end installed on a butt-joint aircraft and an active end installed on an active aircraft. The driving end comprises a lead screw capturing mechanism, a lead screw shell, a capturing in-place triggering mechanism, a transmission shell, a switch frame, a transmission gear, an unlocking in-place triggering mechanism and a locking in-place triggering mechanism, and the lead screw shell, the transmission shell, the motor frame and the switch frame are fixedly connected into an integrated structure in sequence from front to back; the lead screw capturing mechanism is arranged in the lead screw shell and the transmission shell and fixedly connected with the transmission gear, the capturing in-place triggering mechanism sequentially penetrates through the lead screw shell and the motor frame to be kept balanced under the action of the elastic force of the spring, and the locking in-place triggering mechanism and the unlocking in-place triggering mechanism are fixedly connected with the switch frame through bolts. The light and simplified butt-joint locking and releasing device is compact in structure, low in space occupancy rate, capable of being used repeatedly, firm in locking and capable of being applied to various butt-joint separation occasions.

Description

Technical field

[0001] The invention belongs to the technical field of locking release devices, in particular, to a light simplified pair lock release device and its working method thereof. Background technique

[0002] With the sharp exacerbation of human demand for cleaning, the construction of large space solar power plants is increasing, and the modular truss docking is an important part of the construction of large space solar power stations. According to the configuration characteristics of the modular truss mechanism, there is a need for a multi-point distributed independently active docking lock release device. The locking release device for the existing facing docking device has the characteristics of large volume and mass, complex structure, and is not suitable for the truss docking. Docking lock release devices facing modular satellites are relatively large, and cannot meet the compact docking requirements of the truss. In order to satisfy the truss docking for the loc...
