Description

Technical Field

[0001] This utility model relates to flat ingot processing equipment, specifically, to a flat ingot lifting device. Background Technology

[0002] Flat ingots are a common semi-finished product form in metal processing. During processing, flat ingots need to be transferred to different processing areas using lifting equipment and hoisting clamps. For example, Chinese patent CN221759337U provides an aluminum ingot hoisting clamp, including a lifting base, two lifting arms, and two clamping arms. One end of the lifting arm is hinged to the lifting base, and the other end is hinged to the clamping arm. The two clamping arms are hinged in the middle, and the two arms together form an X shape. The clamping arms are divided into an upper clamping arm and a lower clamping arm at the middle hinge point, and the lower clamping arm is longer than the upper clamping arm. A lifting pin can be detachably installed at the end of the lower clamping arm, and several pins are fixed on the clamping surface of the lifting pin. The top of the cylinder and the end of the cylinder rod of the telescopic rod are respectively hinged to the lower clamping arms of the two clamping arms.

[0003] Flat ingots are generally rectangular in shape. When using the lifting clamps in the prior art, in order to ensure the stability of the lifting, they need to be clamped in the middle of the flat ingot for horizontal lifting. However, depending on the different processing requirements of the flat ingot, sometimes it is necessary to lift the flat ingot vertically to the processing area. The existing lifting clamps cannot meet this lifting requirement. Utility Model Content

[0004] The purpose of this invention is to provide a flat ingot lifting device that solves the problem that existing lifting clamps cannot meet the requirements for vertically lifting flat ingots to satisfy different processing needs.

[0005] To achieve the above objectives, this utility model provides a flat ingot lifting device, which includes two jaws hinged together in the middle by a first pin. One end of each jaw is provided with a mounting plate, and the other end is hinged to a connecting rod by a second pin. The ends of the two connecting rods are hinged together by a third pin. A hole is formed in the mounting plate, and a rotating shaft is rotatably arranged in the hole. One end of the rotating shaft is connected to a clamping plate, and a limit hole is formed on the other end. Seats are spaced apart on the back of the mounting plate, and two seats are respectively located on both sides of the rotating shaft. A limit screw is provided on each seat, and the limit screw passes through the limit hole and is tightened with a locking nut.

[0006] Preferably, a bearing is provided inside the hole, and the rotating shaft is at least partially rotatably disposed inside the bearing.

[0007] Preferably, a limiting ring is provided on the rotating shaft, and the mounting plate is located between the limiting ring and the clamping plate.

[0008] Preferably, the surface of the clamping plate is provided with an anti-slip rubber pad.

[0009] Preferably, a lifting ring is fixed on the third pin.

[0010] Preferably, the clamping plate has a circular structure.

[0011] Beneficial effects: This utility model provides a flat ingot lifting device, which includes two jaws hinged together in the middle by a first pin. One end of each jaw is provided with a mounting plate, and the other end is hinged to a connecting rod by a second pin. The ends of the two connecting rods are hinged together by a third pin. A hole is formed in the mounting plate, and a rotating shaft is rotatably arranged in the hole. One end of the rotating shaft is connected to a clamping plate, and a limit hole is formed on the other end. Seats are spaced apart on the back of the mounting plate, and two seats are respectively located on both sides of the rotating shaft. A limit screw is provided on the seat, and the limit screw passes through the limit hole and is tightened with a locking nut. In the first state, the limiting screw passes through the limiting hole on the rotating shaft to prevent the shaft from rotating. In this state, the middle of the flat ingot can be clamped and the flat ingot can be lifted and transported horizontally. In the second state, the limiting screw is removed. In this state, the end of the flat ingot can be clamped. When lifted and raised, the flat ingot can rotate to a vertical state under the action of gravity, and then it can be transported in a vertical state. The flat ingot lifting device provided by this utility model can meet different transportation needs of flat ingots and improve its applicability.
