PIPELINE SUPPORT Russian patent published in 2011 - IPC F16L3/205 

FIELD: machine building.

SUBSTANCE: pipeline support has hollow base secured in ground. Lengthwise slots are made in the base on opposite sides. A pole performing reciprocal motions is positioned in the cavity of the base. With its convex downward an arc-shaped element is fastened by means of brackets on a lower shear of the pole on its internal surface. The arc-shaped element with its whole enveloping arc rests on a flexible element in a groove of the arc-shaped element. Ends of the flexible element are secured on free ends of levers hinged on the base of the support; the levers are arranged at acute angles relative to the base of the support. Vertexes of these angles are directed downward. The levers are spring loaded to the base of the support by means of flat springs with their bend towards levers. Also, with their one end the springs are fastened on the base of the support together with the levers, while with their other ends bent to levers they rest on the base of the support.

EFFECT: simplified design of support and raised reliability of pipeline operation under effect of seismic loads.
