Lifting type turnover cooling bed of billet continuous casting machine

The utility model relates to a lifting type turnover cooling bed of a billet continuous casting machine. The lifting type turnover cooling bed comprises a fixed toothed plate, a movable toothed plate and a lifting hydraulic cylinder, and is characterized in that a billet inlet section is arranged at the front end of the fixed toothed plate and is divided into a horizontal billet inlet section and an inclined-plane billet inlet section; billets are fed from the horizontal billet inlet section and then enter the inclined-plane billet inlet section; an included angle between an inclined plane of the inclined-plane billet inlet section and the horizontal direction is more than 21.8 degrees; gaps among teeth of the fixed toothed plate are X; gaps among teeth of the movable toothed plate are also X; an included angle between a toothed inclined plane of the fixed toothed plate and the horizontal plane and an included angle between a toothed inclined plane of the movable toothed plate and the horizontal plane are more than 21.8 degrees; and the lifting hydraulic cylinder drives the movable toothed plate to move up and down, so that the billets can automatically turn over. By the lifting type turnover cooling bed of the billet continuous casting machine, a transverse-moving hydraulic cylinder can be omitted; and a half of time can be saved during a movement stroke; and the whole turnover cooling bed is simple in structure, the manufacturing cost of the turnover cooling bed can be saved, and production rhythm is accelerated.
