COUPLING JOINT Russian patent published in 2002 - IPC

FIELD: mechanical engineering; coupling joints for sectionalized structures. SUBSTANCE: coupling joint includes at least two structural sections with flanges; flange of subsequent section has central hole, spring-loaded rod with radial end projections; rod is mounted in flange of previous section for axial motion; joint includes also locking mechanism and spring-loaded plate secured on previous section. Locking mechanism is made in form of hooks located diametrically and spring-loaded relative to rod; hooks are secured on axle; they are rotatable in hole of flange of subsequent section and engageable with butt of said flange. Plate embraces rod; it is mounted for radial (relative to rod) motion; plate has inclined sections for engagement with radial butt projections of rod; it is provided with rack part thrown into engagement with operating gear which is engageable with rotation drive. Flange of subsequent section is connected with body of its section by means of bearing; body is provided with gear wheel and flange holds drive with which gear wheel is engageable. EFFECT: enhanced reliability. 1 dwg _
