The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel trunnion ring device at invasive mouth of a river, includes trunnion ring, pivot and "U" shaped plate, the both ends that the trunnion ring is relative are fixed with the pivot, and two curb plates of "U" shaped plate are gone up and are equipped with the through-hole relatively, and the pivot is rotated and is connected the rethread downthehole for the trunnion ring is at "U" shaped plate internal rotation, places invasive mouth of a river in the trunnion ring.
Specifically, the bottom of the U-shaped plate is welded with a support rod, and the bottom of the support rod is perpendicularly welded with a handle.
Specifically, the diameter of pivot is less than the internal diameter of through-hole, and the optical axis is adopted in the inside of pivot contact "U" shaped plate, is equipped with the screw thread in the pivot and in the outside of "U" shaped plate, and the screw thread is screwed the nut for spacing pivot.
Specifically, the width of the U-shaped plate is larger than the diameter of the trunnion ring.
The utility model discloses following beneficial effect has:
the utility model discloses a novel trunnion ring device at invasive mouth of a river
1. The use is flexible, the bracket hook can be detached by replacing the invasive water gap, the lever principle is utilized, the use is light and convenient, the labor is not wasted, the bracket is pressed, the steel turning cannot be caused, and the accident that the steel is stuck to a mechanism during the steel turning is avoided;
2. the trunnion ring moves, the invasive water gap can be adjusted back and forth, the centering effect of the invasive water gap and the crystallizer is obviously improved, the internal and external quality of the billet is improved, and production accidents caused by the deflection of the sleeve are avoided;
