Hinge support capable of relieving impact and vibration

The utility model discloses a hinged support capable of relieving impact and vibration, and relates to the technical field of installation of a speed reducer of a hoisting mechanism of a bridge crane in a plant. The hinged support is a connecting seat which is formed by nesting and hinging a U-shaped connecting plate I and a connecting shaft I, a U-shaped connecting plate II and a connecting shaft II, and a fixed hinge seat and a connecting shaft II at 90 degrees and then is connected between the speed reducer and the trolley frame, and has a degree-of-freedom micro-swing self-adjusting function; and the connecting shaft II and the connecting shaft II are sleeved with radial spherical plain bearings. According to the utility model, the impact and vibration on the high-speed shaft of the speed reducer caused by manufacturing and mounting errors can be effectively reduced, so that the impact damage to the high-speed shaft of the speed reducer is reduced, the probability of safety accidents caused by fatigue dam
