[0002] High-speed wire rod mills are generally capable of rolling round steel with specifications ranging from 5.5mm to 20mm. There are many types of rolling specifications. When changing the rolling specifications, the mill needs to be stopped to replace the roller ring. The roller ring installation tool used in the pre-finishing mill of the high-speed wire rod mill is heavy and needs to be installed with the assistance of equipment such as overhead cranes and cantilever cranes. In addition, the mills of this unit are mostly designed with a 45-degree top angle, so the roller ring installation tool needs to be tilted 45 degrees before installation; Figure 1 As shown, the original roll ring installation tool, the cylinder body is used to install the roll ring. When used on site, it was found that the actual installation of the roll ring was very inconvenient. There are two lifting rings on the top of the cylinder body. When it is directly lifted by the crane sling, the cylinder body is in a vertical state. Two people are required to use a long crowbar to hold the tool to a 45-degree tilt before it can be installed on the rolling mill roll shaft. The operation is relatively difficult. In addition, the crane hoisting tool cannot be rotated on the roll shaft. The crane sling needs to be removed before rotation. At this time, if the installation tool slips, it is easy to cause safety accidents to operators and equipment. Summary of the invention
