Description

Technical Field

[0001] The utility model belongs to the technical field of hot-rolled steel coil processing. Specifically, it particularly relates to an uncoiling device for hot-rolled steel coils. Background Art

[0002] Hot-rolled steel coils, also known as hot coils, use slab (mainly continuous casting billets) as raw materials. After heating, they are made into strip steel by rough rolling mills and finishing mills. The hot strip steel coming out of the last finishing mill is cooled to the set temperature by laminar flow cooling, and then coiled into a strip steel coil by a coiler. When the cooled strip steel coil is in use, an uncoiling device is needed to uncoil it to ensure the use of the steel coil.

[0003] Among them, Chinese Patent CN201822139313.1 discloses a steel coil uncoiler, which includes a base for carrying the steel coil and a bracket on one side of the base. There are two rotatable rollers on the base for carrying and driving the steel coil to rotate. A rotatable support is connected to the bracket, and a telescopic uncoiling shovel head is provided on the support. The steel coil is driven by the rotatable rollers to rotate. When the coil head of the steel coil is located below the uncoiling shovel head and faces the support, the support rotates to make the uncoiling shovel head face the coil head of the steel coil. The uncoiling shovel head extends and peels off the coil head of the steel coil, separating the coil head of the steel coil from the coil body of the steel coil to achieve the uncoiling of the steel coil.

[0004] In the existing uncoiling process, generally, the steel coil is fixed first, and then the coil head of the steel coil is found, and then the coil body of the steel coil is driven to rotate, so that the coil head of the steel coil is separated from the coil body of the steel coil through professional equipment. However, in the existing steel coil fixing structure, generally, after the steel coil is fixed, there is no further auxiliary limiting structure to improve the fixing stability, resulting in the need to further improve the fixing effect on the coil body of the steel coil.

[0005] In response to the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model
