FIELD: machine building. ^ SUBSTANCE: support consists of two resilient members - springs (12), whereon location plate (1) rests, and of frame which contains base (4) and poles (5) and rests on foundation. Rod (13) with sliding bushing (19) is installed inside each spring; the rod is pivotally supported by the frame and passes through an opening in location plate (1). Centring bushing (21) is concentrically inserted into an opening between rod (13) and location plate (1). Between an upper platform of centring bushing (21) and the head of sliding bushing (19) there is left a gap of size dependent on amplitude of location plate (1) variation. Two plates (6) are vertically welded to location plate (1) on both sides; a braking mechanism is hold down to these plates; force of brake mechanism holding down depends on external load. ^ EFFECT: damping vibrate processes form seismic effect and vibration, maintaining required mobility of pipeline. ^ 2 cl, 4 dwg |
