胀圈

Abstract

The utility model provides an expansion ring which is an integral and indivisible Chinese character 'tu'-shaped annular ring with a gap. The expansion ring has enough intensity and tenacity. When a roll bending is transported in the form of hoisting, the expansion ring is inserted into an inner bore of a plate rolling, and a suspension hook of a hoisting machine is contacted with the expansion ring, which brings functions of isolating the suspension hook and the plate rolling, and thus the scratch and the abrasion of the plate rolling in the hoisting-transporting process are avoided, which ensures that the quality of the plate rolling is not affected due to the hoisting transportation.
本实用新型提供一种胀圈,此胀圈为一个整体的不可分割的带有缺口的凸字形环形圈。这种胀圈具有足够的强度和韧性,在吊状运输卷板时将此胀圈插入卷板内孔中,吊车的吊钩与此胀圈相接触,起到隔离吊钩和卷板的作用,避免了卷板在吊装搬运过程中的划伤和磨损,保证不因吊装运输而影响卷板质量。
