LIFTING MECHANISM FOR STEEL-TEAMING LADLES IN STEEL PROCESSING AT RH PLANTS Russian patent published in 2011 - IPC B66C17/10 B22D41/12 C21C7/10 

FIELD: transport.

SUBSTANCE: lifting mechanism 13 is designed to lift ladle 11 filled with liquid steel from teeming ladle car 10 to submerged tubes 22 of vacuum processing vessel at RH plant. Mechanism consists of two supports 14 with their one ends coupled with one or several hydraulic cylinders 21 and provided with mount element 20 brought in contact with ladle holders 12, 29 to move holders relative to lifting supports. The latter have their bearing end fixed in stationary support 17 made up of axially fixed guide 18 arranged on bearing end of said supports on extending hydraulic cylinders of rolling guide 19. In lifting, point 34 of support loading shifts. Said guide 18 representing circle arc features radius and rotational center varying depending upon position of lifting supports to compensate lagle horizontal displacement.

EFFECT: simple and reliable device, ease of servicing.
