The invention relates to an intelligent automatic bag turning
gantry crane which comprises a rack and a bag turning device, the bag turning device comprises a plate hook mechanism and a supporting and turning mechanism, and the supporting and turning mechanism is installed at one end of the rack; the plate hook mechanism is installed on the
machine frame, can reciprocate in the direction from one end of the
machine frame to the other end of the
machine frame and is used for hoisting and conveying the
cinder ladles and conveying the
cinder ladles to the supporting and overturning mechanism, and meanwhile the plate hook mechanism is matched with the supporting and overturning mechanism to conduct
ladle overturning treatment on the
cinder ladles. The
slag ladle overturning device has the beneficial effects of being compact in structure, reasonable in design, capable of achieving stable conveying and overturning of
slag ladles in the metallurgical operation process, high in operation efficiency, concentrated in
slag dumping, convenient to conduct follow-up centralized treatment, safe and reliable.
