Description

Technical Field

[0001] The utility model relates to the technical field of steel coil hooks, in particular to a protection device for steel coil hooks. Background Technique

[0002] In the processing industry of the steel plate surface, generally, steel coils are purchased externally, processed on their surfaces through a production process line, and then rolled into steel coils again, packed and transported out for sale. When the steel coils are purchased, due to the heavy quality of the steel coils, manual unloading is troublesome and laborious. Similarly, after the surface treatment is completed, the steel plates are rolled into steel coils again and transported out after packing. During this process, the steel coils need to be loaded onto vehicles. Similarly, due to the large weight of the steel coils, manual handling is time-consuming and laborious, and the efficiency is low. Therefore, a hook and an electric crane cooperating with it have emerged to lift the steel coils, which can effectively save labor and have high handling efficiency.

[0003] After retrieval, the existing public patent number is: CN201520849053.0, and the public patent name is: A Steel Coil Hook, including a hook body, the body includes a hook body and a cross beam, the hook body and the cross beam are integrally arranged and form an opening for hooking the steel coil. The hook body includes a hanging beam and a connecting arm integrally arranged. A protective layer is arranged on the surface of the hook body, and the protective layer is composed of a soft material. A hanging ring is arranged on the cross beam, and the hanging ring is arranged close to the opening end. By arranging the hanging ring close to the opening position, when hoisting, since the lifting point is not at the parallel point, when hooking the steel coil, the opening will be slightly oriented. In this way, due to the action of gravity, the steel coil will be squeezed against the connecting arm and will not slide towards the opening position. In this way, it is ensured that the steel coil will not slip during the hoisting process, and the protective layer of the soft material can ensure that the steel coil will not be damaged during hoisting.

[0004] However, the structure adopted in the above device is not safe enough. When the steel coil shakes, it may cause the steel coil to break away, resulting in a safety accident, and there is room for improvement. Summary of the Utility Model
