An unlocking and resetting device for a transfer mechanism

Abstract

The invention, which belongs to the field of the transfer mechanism, particularly provides an unlocking resetting device for a transfer mechanism. An active resetting mechanism includes a motor A, a mounting substrate, a winching wheel and a pull belt. A ratchet unlocking mechanism consists of a base, an unlocking mechanism, ratchets and guide rails. The motor A is installed at the mounting substrate and the output end is connected with the winching wheel; and one end of the pull belt is connected with the winching wheel and the other end is connected with the base. A plurality of ratchets and a plurality of guide rails are distributed uniformly at the peripheral surface of the base; and a support wheel is arranged at each ratchet. The unlocking mechanism includes a motor B, a lead screw, a nut and cam sliding blocks; the output end of the motor B is connected with the lead screw; the nut and the lead screw are in threaded connection; a plurality of cam sliding blocks are distributed uniformly at the nut and are abutted against the support wheels; all cam sliding blocks make reciprocating motions with the nut along the axial direction; and the support wheels roll with the cam sliding blocks, so that radial extending or contraction of all ratchets can be realized. A problem of multi-times repeated performance testing of the transfer mechanism can be solved; the manual operation load can be reduced; and the test efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of transfer mechanisms, in particular to an unlocking and reset device for a transfer mechanism. Background technique [0002] In the third phase of space exploration, the lunar rover will retrieve some lunar soil samples from the lunar surface, transport them back to space and dock with the orbiter by the ascender, transfer the lunar soil samples to the orbiter, and finally transport them back to Earth. The transfer mechanism after the ascender and the orbiter are docked adopts a ratchet stepping method to realize the transfer and locking functions of the transfer chamber. The real transfer chamber cannot be automatically unlocked and reset after it is locked in place, so that repeated ground tests cannot be realized. . Contents of the invention [0003] In order to solve the problem of multiple repeated tests of the transfer mechanism, the object of the present invention is to provide an unlocking and reset devic...

Problems solved by technology

The transfer mechanism after the docking of the ascender and the orbiter adopts a ratchet stepping method to realize the transfer and locking functions of the transfer chamber. The real transfer chamber cannot be automatically unlocked and reset after it is locked in place, so that repeated ground tests cannot be realized.
