Description

Technical Field

[0001] The utility model relates to the technical field of copper strip processing, in particular to an efficient replacement sling for the guide roll of a copper strip rolling mill. Background Technique

[0002] Copper strip processing mostly uses a copper strip rolling mill. After the guide roll of the copper strip rolling mill is used for a period of time, it needs to be disassembled and replaced. When the copper strip rolling mill is shut down for maintenance, the guide roll is mostly hoisted and replaced by a hoisting device and an auxiliary sling. At present, the auxiliary sling includes a cross beam, and two hooks are arranged at the lower parts of both ends of the cross beam. The guide roll is hoisted by hooking the hooks on the neck of the guide roll. The length of the existing sling cannot be adjusted according to the size specifications of the guide roll. A lot of slings with different size specifications need to be made in the workshop, and the cost is relatively high, and the use efficiency of the sling is low.

[0003] For example, a replacement sling for the working roll of a rolling mill disclosed in Chinese Patent CN206359117U includes a cross beam and a rope for binding the working roll. Hook assemblies for hooking the ropes are arranged at both ends of the lower end face of the cross beam. The hook assembly includes two hooks connected back to back. A lifting lug is arranged in the middle of the cross beam, and the lifting lug is connected to an electric hoist through a rope. The hook includes a bent part, and the plane where the bent part is located is perpendicular to the side face of the cross beam, and the bent part of the hook extends outside the area surrounded by the downward extension planes of the two opposite side faces of the cross beam. The size specifications of the sling cannot be flexibly adjusted according to the length of the working roll. Content of the Utility Model
