FIELD: rolled stock production, namely supporting ends of cantilever type drums of coiling-uncoiling machines at process of coiling - uncoiling. SUBSTANCE: hinged support of coiler includes supporting part mounted on rotary bracket with piston drive and leverage system for fixing rotary bracket in working position. Said system is in the form of lever driven to rotation by means of its own piston drive and having on end stop platform arranged with possibility of engaging with wedge surface of rotary bracket whose inclination angle is selected according to condition of self-braking. Lever with stop platform is provided with unit for forcing it to said wedge surface. Piston drive of rotary bracket is connected to source of constant pressure and it serves as unit for forcing stop platform to wedge surface of rotary bracket. EFFECT: reliable engagement of supporting portion with shaft of coiler. 2 cl, 1 dwg |
