Abstract

The invention discloses a cabin door unlocking device. The cabin door unlocking device comprises a nut component, a locking-unlocking component and an operating tool, wherein the nut component is installed on an aircraft structural component, the center of the nut component is provided with a first inner threaded hole, the operating tool is installed at the tail end of a mechanical arm with a rotating function, the center of the operating tool is provided with a second inner threaded hole, the locking-unlocking component is fixedly connected with a cabin door and comprises a locking-unlocking screw, the lower end of the locking-unlocking screw is provided with a first thread matched with the first inner threaded hole, the upper end of the locking-unlocking screw is provided with a second thread matched with the second inner threaded hole. According to the cabin door unlocking device, the cabin door can be reliably locked by screwing the first thread into the first inner threaded hole, meanwhile, the cabin door can be locked and unlocked by controlling the operating tool through the mechanical arm, and the cabin door unlocking device has the beneficial effects of simple structure, small weight, reliability in locking and unlocking, and the like.

Description

Technical field [0001] The invention relates to the field of aerospace technology, in particular to a locking and unlocking screw and a cabin door locking and unlocking device. Background technique [0002] With the development of spacecraft in-orbit service module replacement technology, it has been considered to use cabin doors to protect related replaceable modules from space debris impact, radiation and thermal environment. With the increase of the door structure, in order to meet the vibration and shock conditions during the launch phase, it is necessary to adopt a locking device with a reliable connection function, and after the aircraft is launched into orbit, it is convenient to use a robotic arm with a rotating function to achieve alignment. The unlocking of the hatch. [0003] At present, the replacement technology of the spacecraft on-orbit service module is in the initial pre-research stage. There is no ideal solution that can achieve reliable locking of the cabin door...
