Description

Technical Field

[0001] The utility model relates to the technical field of sling equipment, in particular to a sling for slinging working rolls of an aluminum foil rolling mill. Background Art

[0002] During the production of aluminum foil, the working rolls of the aluminum foil rolling mill need to be maintained and replaced periodically to ensure the quality of the produced aluminum foil. Currently, during the lifting and replacement of the working rolls of the aluminum foil rolling mill, a lifting rope with multiple hooks is usually used to lift the working rolls. In this lifting method, since the hooks are all in a rigid and irregular state, the lifting process is often time-consuming and labor-intensive, the hooks are very likely to scratch the working surface of the working rolls, and the working rolls are damaged more frequently, which ultimately results in a low lifting rate for the working rolls of the aluminum foil rolling mill and affects its overall production efficiency. Utility Model Content

[0003] The utility model provides a hoisting device for hoisting working rolls of an aluminum foil rolling mill, so as to solve the problems existing in the above background.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A lifting device for lifting the working roll of an aluminum foil rolling mill comprises a lifting lug support, a main shaft hole is provided at the center of the lifting lug support, a roll placement platform is provided on the top of the lifting lug support, an arc surface is provided on the bottom of the lifting lug support, and a rope hanging groove is also provided on the arc surface.

[0006] Furthermore, the ear support is symmetrically provided with a first through hole and a second through hole on both sides of the main through-shaft hole, and a buffer hole is also provided on one side of the main through-shaft hole.

[0007] Furthermore, both sides of the arc surface are provided with limit platforms, and the hanging rope groove is located between the limit platforms.

[0008] The utility model has the following beneficial effects:

[0009] The utility model provides a hoisting device for lifting the working rolls of an aluminum foil rolling mill, which is mainly composed of components such as a lifting ear support, a main shaft insertion hole, a roller placing platform and a rope hanging groove. By placing the roller placing platform of the hoisting device flush with the ear plate of the working roll, the end shaft of the working roll is passed through the main shaft insertion hole, and the lifting hanging rope is clamped in the rope hanging groove, matching the limit of the rope hanging groove limit table, the hanging rope is effectively used to lift a plurality of working rolls quickly and safely, further improving the overall lifting rate of the working rolls, ensuring the overall production efficiency of the aluminum foil rolling mill, and solving the problem that in the current lifting process of the working rolls of the aluminum foil rolling mill, the working rolls are generally lifted by using a lifting rope with a hook, which usually results in a time-consuming and labor-intensive lifting process, the hook is very likely to scratch the working surface of the working roll, and the working roll is damaged more frequently, which ultimately causes a low lifting rate of the working rolls of the aluminum foil rolling mill and affects its overall production efficiency.

[0010] The arrangement of the buffer hole in the utility model effectively avoids the stress on the end shaft of the working roll and the rigid extrusion of the lifting lug support during the working roll lifting process, realizes the gap transition of the end shaft, and further ensures the overall high efficiency of the working roll lifting and the roll surface quality accuracy.

[0011] The arrangement of the first through hole and the second through hole in the utility model realizes the reasonable matching of the end shaft and the lifting lug support when working rolls of different models are lifted, thereby effectively expanding the application scope of the lifting device.

[0012] The arrangement of two rows of limit platforms in the utility model effectively avoids the loosening and deviation of the hanging rope during hoisting in the hanging rope groove, thereby ensuring the safety of the working roller during transportation and improving the overall hoisting efficiency of the working roller.
