Problems solved by technology

The spring force of the mortise lock of the main leg is relatively large, and the main leg is inclined when the arrow is assembled, and the position of the mortise lock is different, which brings great difficulties to the unlocking operation
[0003] At present, there is no large spring force mortise lock unlocking method and tooling that can be referred to at home and abroad. The existing tooling requires a crane to cooperate with hoisting, and the quality is relatively heavy. At a certain angle of inclination, even if there is an additional crane to cooperate with the hoisting, the centering requirements of the locking lever cannot be well met when unlocking

Abstract

The invention discloses an on-rocket splicing type adjustable tenon lock pressing and unlocking device. Pressing and unlocking assemblies are spliced on each section of landing leg hoops through transverse strip assemblies, can axially translate along the landing leg through transverse strips, and are well matched with the position change of a tenon lock in the leg retracting process. The tenon lock is subjected to pressing and unlocking operation through the combined action of a pressure applying mechanism and a limiting boss arranged on a rear cover plate, the pressing and unlocking device is of a spliced type and can be attached to the landing leg for positioning and unlocking, convenient centering of the pressing and unlocking device of the tenon lock and the tenon lock is achieved, cooperation of a crane is omitted, the extra crane cost can be reduced, and the unlocking operation process can be simplified. The invention further discloses a pressing and unlocking method based on the pressing and unlocking device.

Description

technical field [0001] The invention relates to an arrow splicing adjustable tenon lock unlocking device, in particular to a vertical take-off and landing rocket landing leg tenon lock press lock unlocking device and method, belonging to the tenon lock press lock unlocking field. Background technique [0002] Vertical take-off and landing is an effective way for today's launch vehicles to achieve reusability. It has been practically verified by the American private aerospace company SpaceX, including the rocket sub-stage, fairing and the main structure of the landing legs are all reusable. Among them, the reliable deployment of the landing legs and the locking of the mortise lock directly affect the success or failure of the rocket recovery. The spring force of the mortise lock of the main leg is relatively large. When the arrow is assembled, the main leg is inclined and the position of the mortise lock is different, which brings great difficulties to the unlocking operation...
