Problems solved by technology
[0002] The nut of the mechanical pressing device of the rolling mill is installed in the mounting hole on the top of the (rolling mill) frame. During installation, it needs to be hoisted in from the window of the frame (the nut is installed from the bottom of the nut mounting hole). The traditional construction method is to directly hoist it by driving. It is installed in place through the cooperation of hand chain hoists, and the following problems will occur during the installation process: 1. It is unstable during hoisting, and it is easy to collide with the rolling mill frame, destroying the processing surface and affecting the installation accuracy of the equipment; and the construction personnel need to use manpower to stabilize the equipment Positioning is difficult. 2. The gap between the pressed nut and the installation hole is small. If the nut is tilted during hoisting, it cannot be installed in place smoothly. Repeated adjustments are required, and the installation efficiency is low.
