SEPARATION DEVICE OF STRUCTURE ELEMENTS Russian patent published in 2013 - IPC F16B1/00 B64G1/64 

FIELD: machine building.

SUBSTANCE: separation device of structure elements, which contains a housing with a cylindrical cavity, a piston, a shank, a compressed gas supply channel, as well as a separated element, which differs by the fact that in internal cylindrical cavities there arranged are two additional pistons located symmetrically relative to the device axis and including two-sided stocks. On stocks facing the device axis there made are bevelled sections adjacent to a lock element made in the form of a flattened cone, the generatrixes of which are parallel to bevelled sections of stocks, and the lock element is connected through the shank to the separated object. Pistons interact with springs that are borne against cover plates of the housing, and on the stocks going out of the cylinder outwards, on both sides there made are flats; at that, travel of pistons is determined by relationship x_p= l₂-l₁, and value of travel meets the following condition: x_p>δ, where: l₁ and l₂ - distance from symmetry axis of the device to the top of the stock chamfer respectively before and after separation of the structure; δ - overlapping value of surface of the adjoined element to cylindrical surface of the bevelled stock; at that, gap Δ is made between the housing and the lock element.

EFFECT: providing repetition of actuation of the device and possibility of inverse connection of structure elements for re-use.
