An integrated sand control and grease storage missile linkage locking device

Abstract

The invention discloses an integrated type sand-prevention lipid-depot guided missile linkage locking device. The device comprises multiple locking units which are connected in sequence, and each locking unit comprises a foundation and a lead screw respectively, wherein the lead screw is rotatably fixed on the foundation, the two ends of the lead screw stretches out of the two ends of the foundation and are connected with the corresponding ends of the lead screw of the adjacent locking unit, a pressing block is arranged on each lead screw in a sleeving mode, and the lead screw and the pressing block form a helical kinematic pair; the pressing block is in wedge contact with an external storage and transportation launching canister clamping part self-blocking slope, a storage and transportation launching canister locating surface is arranged corresponding to the outer side of the storage and transportation launching canister clamping part, when the lead screw is rotated, the pressing block moves in the axial direction of the foundation, so that the storage and transportation launching canister clamping part props outwards or retracts inwards and afterwards pushes against or breaks away from the storage and transportation launching canister locating surface, thus locking and unblocking of the storage and transportation launching canister can be achieved, and the problem that the storage and transportation launching canister gets loosen caused by vibration and impacting in a transportation process is thus avoided. The integrated type sand-prevention lipid-depot guided missile linkage locking device has the advantages that a reinforcement hoop at the front part of the guided missile storage and transportation launching canister can be compressed through the torsion of an axle end, the axial-direction locking of multiple launching canisters in a container frame is achieved, and the axial-direction sliding can be avoided.

Description

technical field [0001] The invention relates to the technical field of ground launching devices, in particular to an integrated sand prevention and grease storage missile linkage locking device. Background technique [0002] The missile linkage locking device is mainly composed of a base, a screw, a briquetting block and a coupling. There is a helical motion pair between the screw and the briquetting block. When the screw is rotated, the briquetting block moves axially along the base to realize storage and transportation. Locking and unlocking of the launching tube (box). The clamping part of the pressing block and the launch tube (box) adopts the principle of inclined plane fit, and the clamping function is realized by friction. The self-locking design is adopted for the fit between the screw pair and the inclined plane, so as to avoid the loosening of the linkage locking mechanism due to vibration and impact during transportation. The linkage function is realized through...

AI Technical Summary

Problems solved by technology

[0003] Linkage locking requires high coaxiality between multiple screw screws. Due to assembly errors or deformation of the installation reference of the locking device after multiple lifting and transportation of the pallet, the coaxiality between multiple screw screws become worse, resulting in increased torsional moment, locking and stagnation, laborious

[0004] If the lead screw is exposed to rainwater and wind and sand for a long time, it is prone to rust or erosion, resulting in laborious locking and sticking, so it is necessary to coat the lead screw frequently for protection
