Description
Technical Field
The utility model belongs to the technical field of metallurgical casting cranes, and particularly relates to an automatic positioning hook and unhooking early warning device of a bridge type metallurgical casting crane.
Background
In recent years, with the rapid development of smelting enterprises, the use of metallurgical casting cranes has been increasing, and the frequency of safety accidents caused by the falling of molten metal ladle due to unhooking of a lifting hook has also been increasing. From the analysis of accidents, the main reason that the molten metal ladle falls and overturns is found to be that the lifting hook does not lift the hook head to the lower part of the trunnion in the lifting process, so that the lifting hook is separated from the trunnion in the lifting or pouring process, and the safety accidents are caused. The existing method for solving the problem that the lifting hook is separated is mainly to prevent unhooking by limiting the lifted object by adopting an anti-falling buckle, however, the prior art cannot accurately judge the specific condition of the lifting hook during working by an operator, and accurately adjust the lifting hook according to the specific condition of the lifting hook so as to prevent the safety accident caused by unhooking caused by various abnormal conditions of the lifting hook. Therefore, it is necessary to provide an automatic positioning hook and unhooking early warning device of a bridge metallurgy casting crane.
Disclosure of Invention
