Spacing adjusting assembly and adjusting device for hoisting crystallizer

The utility model discloses a spacing adjusting component and an adjusting device for hoisting a crystallizer, which belong to the technical field of continuous casting crystallizer overhauling, and comprise a hoisting cross arm, a first I-shaped roller moves to drive adjacent transmission rods on adjacent transmission mechanisms to act through a connecting rod, so that the connecting rod and the adjacent transmission rods move symmetrically, and the hoisting cross arm is used for hoisting the crystallizer. The adjacent transmission rods move to drive the other transmission rod on the same transmission mechanism to act through the two meshed half gears, so that the distance between the two adjacent mounting plates is synchronously increased or decreased; therefore, the distance between every two adjacent crystallizers is synchronously adjusted, the crystallizers can be synchronously hoisted and replaced through the multiple installation plates, and the replacement efficiency of the crystallizers is improved.
