Embodiment Construction

[0015] The following is a further detailed description of a hanger for large steel ingots and forgings of the present invention through specific embodiments.

[0016] Such as figure 1 As shown, it includes two pliers arms 1 and two pliers claws 2, the middle parts of the two pliers arms 1 are hinged by the first pin shaft 3, and the lower ends of the two pliers arms 1 are respectively fixedly connected with the two pliers claws 2, and the two pliers arms 1 are fixedly connected to each other. Pin shafts are installed on the upper ends of the pins, respectively the second pin shaft 4 and the third pin shaft 5. Cover plates are installed on the pin shafts, and the two jaws 2 cooperate to clamp large steel ingots and forgings.

[0017] Preferably, the jaws 2 are provided with gaps for clamping the workpiece. In this embodiment, the jaws 2 are U-shaped, and the arms 1 and jaws 2 are made of low carbon steel.

[0018] When hoisting, the auxiliary chain is wound around the lower en...

Abstract

The invention discloses a lifting tool for a large steel ingot and a large forge piece. The lifting tool for the large steel ingot and the large forge piece comprises two clamp arms and two clamp claws, wherein the lower end parts of the two clamp arms are fixedly connected with the two clamp claws respectively; the middle parts of the two clamp arms are hinged through a pin shaft; a cover plate is installed on the pin shaft; and the two clamp claws are matched to clamp the large steel ingot and the large forge piece. The lifting tool for the large steel ingot and the large forge piece is simple in structure, convenient to install and detach and non-hazardous in operation, is applicable for lifting the large steel ingot and the large forge piece, can be operated only by a crane operator, without needing other auxiliary workers, thus saving manpower to a certain extent, is strong in practicality, can improve the productivity, reduce the labor intensity and the operating dangerousness of working staff, meets lifting requirements of the large steel ingot and the large forge piece, and achieves safe and reliable lifting work; the workpiece clamping principle of the lifting tool for the large steel ingot and the large forge piece is different from that of an ordinary lifting tool, and a clamping force is generated by self weight of a workpiece, so that the lifting tool meets requirements on structural strength and rigidity, has good clamping performance and is material-saving.

Description

technical field [0001] The invention relates to the field of hangers, in particular to a hanger used for large steel ingots and forgings. Background technique [0002] With the vigorous development of my country's industrial construction, equipment in metallurgy, machinery, electric power, petroleum, chemical shipbuilding, aviation, defense industry and some light industries are all developing in the direction of large capacity, high power and high performance. The weight and size requirements are getting larger and larger, and the resulting large forgings (referred to as large forgings) are the basis of heavy machinery manufacturing. Large forgings have notable characteristics such as large shape and weight, many varieties of production, and high quality requirements. In the production process of large iron and steel manufacturing enterprises, the lifting and transportation of large steel ingots and forging products is a very heavy and dangerous work, especially the lifting...
