[0002] With the rapid development of the national economy, the development of industrialization and the continuous progress of science and technology, cranes have been rapidly developed and widely used. Cranes are widely used in various fields of economic construction and are used more and more frequently and widely. Our country continues to Various types of mines and oil fields have been explored. Most companies manufacture their own spreaders. There is a big gap in professionalism and safety. The crane hook is an indispensable part of the crane. The common crane hook has only one hook head. Composition, a single hook head cannot guarantee the balance of the lifting operation during the lifting operation, and the lifted object is easy to shake in the air due to poor balance during the lifting process. In severe cases, it is easy to cause the lifted object to tilt. Items cause damage and cause property loss. In order to make up for the shortcomings of the single hook, people invented a double hook head hook. Although the double hook head can improve the defect of the single hook, the hook with an integrated structure is mostly used. , the hook of the integrated structure has poor mobility, and the balance cannot be adjusted by itself during the lifting process. The balance cannot be guaranteed, and it cannot meet the lifting requirements of some demanding precision lifting items. The hook is an important guarantee for safe lifting during the lifting process. In order to ensure the safe operation of the crane hook, the hook of the crane needs to be equipped with an anti-decoupling device. Composed of a return spring, the tongue will be disengaged from the hook due to loosening of the device or moving outward due to external force, and the protection function will be lost. Decoupling protection function, the tongue is easily deformed, falls off and loses its original protective effect. The width of the lifting lug that comes with the crane hook is small, which makes the tongue connected to it easy to move left and right. As the working time increases, the tongue will Deformation, short service life, detachment from the hook, resulting in an accident when the crane is lifting the cargo, it is easy to cause safety accidents, causing casualties and property losses, and there are potential safety hazards. Therefore, it is necessary to design a reasonable design and simple structure. The self-balancing crane hook is compact, easy to install and use, saves time and effort, has good anti-decoupling effect, self-balancing, high working efficiency, good balancing effect, stable lifting, safe and reliable, wide application range and long service life. Necessary and of great significance to the safe use and development of cranes
