Ladle tipping device for ladle crane

Abstract

The invention belongs to the technical field of crane hoisting, and provides a ladle tipping device for a ladle crane, which comprises a hoisting assembly and a lifting hook body, the upper part of the hoisting assembly is connected with an auxiliary hoisting mechanism, and the lower part of the hoisting assembly is hinged with the lifting hook body. And the hoisting assembly comprises a plurality of hoisting sections, and the adjacent hoisting sections are hinged, so that each hoisting section can swing. The lifting hook body comprises a connecting part and a hook head; one end of each connecting part is hinged to the corresponding hoisting section, the other end of each connecting part is provided with a hook head, the connecting parts extend towards one side of the hoisting assembly, and the hook heads are located on one side of the central axis of the hoisting assembly in the state that the ladle is not hung; in the state of hanging the ladle, the connecting part rotates around the hinge point relative to the lifting assembly, so that the hook head is located on the central axis of the lifting assembly. The ladle tipping device disclosed by the invention has safety and flexibility, and a crown block worker can independently finish hooking and unhooking operations.

Description

technical field [0001] The invention belongs to the technical field of crane lifting, and in particular relates to a ladle tipping device for a casting crane. Background technique [0002] The main function of the crane is to be responsible for lifting and transporting, which has extremely high requirements for work safety, and the lifting safety of casting cranes is the top priority. Almost every lifting accident of casting cranes will lead to serious equipment losses. and casualties. In the process of steelmaking production, it is usually necessary to use the fixed gantry hook of the main lifting mechanism of the foundry crane to lift the ladle, and pour the molten iron in the ladle into the electric furnace or converter through the ladle tipping device for smelting, while In the process of ladle tipping, improper use of tipping devices will greatly increase the accident rate. [0003] Under the premise of ensuring safety during the ladle lifting and tipping process, it ...

AI Technical Summary

Problems solved by technology

[0005] The ladle tilting device has the following problems: 1. When tipping, because the hook head deviates from the center line of the wire rope, it is easy to accidentally unhook; Frequent manual operation is not only dangerous, but also affects the production rhythm; 3. The safety and stability of the steel wire rope for lifting molten metal is poor, the wire rope wears quickly, is easy to break, and needs to be replaced frequently; 4. Possible interference during the hook and hook removal process 5. The position of the hook head of the hook body is easy to wear, and usually the entire hook body needs to be replaced due to damage to the hook head, resulting in a waste of resources
