Lifting appliance mechanism capable of turning over product

A rotary fixing sleeve is sleeved on the outer diameter of a rotating shaft, the rotating shaft is mounted below a transition plate of a rotating shaft welding assembly, a transition shaft is mounted above the transition plate, a mounting plate is mounted on the transition shaft, hoisting and overturning are performed together, and the lifting appliance is a lifting appliance and an overturning machine. The lifting hook support welding assembly is composed of a lifting ring lifting hook support rotating shaft fixing sleeve. The rotary fixing sleeve mainly plays a role in rotating and supporting. The axis of the shaft sleeve of the whole lifting hook support welding assembly and the vertical line of the lifting ring pass through the gravity center of a product, the product is always in a vertical state in the product lifting process, and the overturning rotating shaft coincides with the gravity center of the product. Therefore, the product can be overturned easily and conveniently in the overturning process, t
