The fixed frame 1 can be installed near the holes of the cold rolling mill unit, the end of the walking beam, the uncoiler, and the ground roller. There are holes in the cold rolling mill unit, the end of the walking beam, the uncoiler, and the ground roller, which can easily lead to falls when personnel work in this area. The fixed frame 1 is U-shaped, and rollers 3 are slidably connected to the inner wall of the fixed frame 1. A cover plate 2 for covering the holes is fixedly connected to the rear surface of the rollers 3. There are two sets of rollers 3, evenly distributed on the left half of the front and rear sides of the cover plate 2. A protective mechanism is provided on the front surface of the cover plate 2. The protective mechanism can cover the small holes at the uncoiler and the ground roller without affecting the normal use of the device and the line of sight.

A limit component is provided on the rear surface of the fixed frame 1. The protective component includes a connecting plate 41. A flip plate 43 is hinged to the top of the front surface of the connecting plate 41 via a hinge 42. There are two types of flip plates 43: one with a larger area, which can cover the small holes at the unwinder and the ground roller, and the other with a smaller area, which can be used to fill the gaps on both sides of the unwinder and the ground roller. The positioning component includes a slider 51. A positioning block 52 is fixedly connected to the rear surface of the slider 51. The slider 51 and the positioning block 52 will move synchronously. An insert block 54 is elastically connected to the inner wall of the connecting plate 41 via a compression spring 53. A slot 502 is provided on the front surface of the cover plate 2. A positioning groove 501 is provided on the left surface of the insert block 54. There are two sets of slider 51, positioning block 52 and positioning groove 501, which are symmetrically distributed on the left and right sides with respect to the center line of the insert block 54.
