Description

Technical Field

[0001] The utility model relates to the technical field of anti - unhooking devices, in particular to an anti - unhooking device for an overhead single - girder crane. Background Technique

[0002] The crane hook is an important part of the crane and plays an important role in the whole lifting process, bearing all the lifting loads. Its safety directly affects the operation of the crane. During use, once the hook is unhooked, damaged or broken, major accidents will occur. During use, it is necessary to regularly check whether there are safety hazards on the hook. To prevent the unhooking phenomenon during use, a device to prevent the lifted object from falling off can be set on it.

[0003] In the Chinese utility model patent application publication specification CN202220851623.X, an anti - unhooking crane hook is disclosed. In the existing crane, the hanging rope is fixed by a hook. The hook ring part of the crane hook is an arc structure, which makes the hanging rope easy to move, resulting in the unhooking of the hanging rope. Currently, the anti - unhooking structure for cranes usually adds a structure for spring and clamping plate blocking at the hook ring part to prevent the hanging rope from unhooking, but the use effect is poor. Therefore, an anti - unhooking device for an overhead single - girder crane is needed. Summary of the Utility Model
