The invention discloses a universal steel coil hoisting protection device which comprises an arc-shaped end face protection plate. The arc-shaped end face protection plate is fixed to a semi-cylindrical inner hole protection plate; the semi-cylindrical inner hole protection plate is provided with a plurality of stepped slotted holes; the tail ends of magnets are embedded into the stepped slotted holes; the heads of the magnets penetrate through the stepped slotted holes; and the outer contours of the heads of the magnets are consistent with the outer contour of the semi-cylindrical inner holeprotection plate. The universal steel coil hoisting protection device provided by the invention has the advantages that the a rubber protection ring is attracted to a core hole and the side end of a steel coil through the magnets, and the radian of the rubber protection ring can be changed along with the change of the core hole, so that the universal steel coil hoisting protection device has universality.
本发明公开一种通用钢卷吊装保护装置,包括弧状端面护板,所述弧状端面护板与半圆柱状内孔护板固定;所述半圆柱状内孔护板设置多个阶梯槽孔,磁铁的尾端嵌入所述阶梯槽孔中,磁铁的头部穿过所述阶梯槽孔且磁铁的头部外廓与半圆柱状内孔护板的外廓一致。本发明的优点是:由于采用了磁铁将胶护圈吸附在钢卷的芯孔及侧端部,且胶护圈的弧度可随芯孔的变化而变化,因此,具有通用性。
