Abstract

The utility model provides an ingot tilting clamp for a crane lifted ingot. The clamp comprises a lifting ring, a clamp upper beam, inner and outer pulling plates, inner and outer clamp bodies, a ingot middle beam, an opening/closing mechanism, a lock base plate, a clamping base, a V-shaped driven locating device, a rotating chuck, a balancing weight and an automatic claw lock. The ingot clamp disclosed by the utility model not only reserves a lifting function of a normal vertical clamp but also has an ingot tilting function of converting an ingot from the horizontal position to the vertical position or from the vertical position to the horizontal position. The tilting clamp is simple in structure, high in mechanical strength, long in service, low in cost, and capable of avoiding possible potential safety hazards due to ingot tilting by manpower, reducing auxiliary equipment for the special steel production, shortening the ingot tilting and lifting time, improving the working efficiency, reducing the production cost and enhancing the market competitiveness.
