Problems solved by technology

Unfortunately, this mechanism is outside the capture mechanism and does not have a telescopic function. During the satellite capture process, it is possible to hit this part of the mechanism instead of the external guide structure of the cone-rod mechanism, which may easily cause capture failure or even cause a coronary. Damage to the expansion locking mechanism

Abstract

The invention discloses a telescopic locking mechanism driven by a leading screw. The telescopic locking mechanism comprises a guide rail and a screw mechanism, wherein one end of the screw mechanismis mounted with a fixing seat. The screw mechanism and the fixing base are connected by a fixing sleeve, and the fixing sleeve is equipped with a power device for driving the movement of the screw mechanism. The other end of the screw mechanism is mounted in the guide rail, and the screw mechanism realizes a telescopic movement with respect to the guide rail. One end, in the guide rail, of the screw mechanism is equipped with a locking device. The invention discloses a cone bar capturing locking mechanism driven by the screw principle, the telescopic and expansion capture action is completed by a driving motor, thereby streamlining the control system and making full use of the space. In addition, the whole mechanism is in rigid transmission and precise in transmission.

Description

technical field [0001] The invention belongs to the technical field of on-orbit service and maintenance of aerospace satellites, and relates to a telescopic locking mechanism driven by a lead screw. Background technique [0002] The geostationary orbit, also known as GEO, is an important earth orbit resource for human beings. The on-orbit resources are limited by the orbital position and are extremely scarce. However, with the rapid development of space missions, the total number of satellites in the GEO belt contains more than 40% of uncontrollable or abandoned satellites and their wreckage. These space objects have a long natural fall cycle and pose a threat to the safety of GEO satellites in normal operation. It also leads to a serious waste of GEO orbital resources. Another statistics show that among the GEO satellites that have failed in orbit, more than 50% of the failures are due to the loss of a certain function of the service system, while the payload and platform ...
