Description

Technical Field

[0002] The grinding wheel used on the cylindrical grinder has a large diameter and weight, and needs to be installed with the assistance of a grinding wheel hanger. The traditional grinding wheel hanger needs to be hoisted by a crane, and the swing back and forth during the hoisting will cause the grinding wheel to collide with the main shaft of the grinding wheel hanger many times, damaging the grinding wheel and the main shaft. In addition, when the traditional grinding wheel hanger replaces the grinding wheel, the up and down adjustment error of the crane is too large, the center height is difficult to control, and there are problems such as long line change time and cumbersome operation, which greatly reduces work efficiency. Therefore, a new type of grinding wheel hanger is specially designed. Utility Model Content
