Claims

LIFTING AND TURNING DEVICE FOR INSTALLING THE INTERMEDIATE BUCKET ON THE CONTINUOUS METAL CASTING MACHINE, comprising a rotary column with a platform fixed on it, characterized in that, in order to ensure the bucket to be centered relative to the molds, the intermediate bucket is mounted on two pivotally mounted between them and mounted on a pivotally mounted platform traction levers that are associated with self-braking worm-wing mechanisms.

2. Lift and swivel device pop. 1, characterized in that in the guide levers are placed movable parts connected with self-locking worm-screw mechanisms, on which an intermediate bucket is mounted with the projections of the pins.

d parts on which trunnions are mounted on the trunnions.

In FIG. 1 shows a hoisting device with an intermediate bucket, top view ”in FIG. 2 is a section along AA in FIG. 1.

An intermediate bucket 1 with protrusions 2 pins 3 is mounted on movable parts 4 included in sliding guides 5 made in levers 6. The levers are pivotally mounted on a platform 7 mounted on a rotary column 8 and connected to each other by an articulated rod 9.

15 The rotation of the levers is carried out using a worm-screw self-braking mechanism 10, and the sliding of parts 4 in the guides 5 using two worm-screw self ²⁰ braking mechanisms 11 and 12.

After installing the intermediate ladle 1, the casting holes 13 and 14 are centered relative to the molds 15 and 16.

At the same time, the mechanism 10 is rotated for regulation in the B direction. The worm-screw mechanisms 11 and 12 are separately rotated for the regulation in the B direction, achieving coaxial position of the casting holes 13 and 14 relative to the molds 15 and 16.
