Center alignment method of large-sized equipment

Abstract

The invention discloses a center alignment method of large-sized equipment. The center alignment method comprises the following steps of: after adjusting the level and the elevation of the equipment, rechecking the size from a coupling to the center of the equipment according to the size of a drawing; copying a rolling central line to the space above the coupling and reserving a size for a detection tool; pulling a steel wire; fixing a solid bracket on the coupling of the equipment; turning the coupling to ensure that the space between two crossed points of the swing amplitude of the bracket and the steel wire is greater than 1 meter; lifting a cord drop in the middle of the two points to detect a horizontal state and a center deviation when necessary; fixing a micrometer rod on the bracket; swinging the bracket to align the micrometer rod with the steel wire; adjusting the reading of the micrometer rod; adjusting the horizontal displacement of the equipment; and ensuring that the readings at two sides of the micrometer rod and the steel wire are less than a design permissible error value. The center alignment method is used for simplifying the alignment processes of the equipment and is simple in operation and convenient and practical; the error of a couple of millimeters per thousand in the permissible error requirement of the coupling can be directly read after an end face of the coupling is amplified, the adjustment is facilitated, conversion is not required, and the alignment working efficiency is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of installation alignment of large-scale equipment, and is mainly applicable to the installation of large-scale equipment in production lines such as steel rolling, cast pipe, high-speed wire rod, annealing and pickling. Background technique [0002] At present, in the process of equipment alignment and positioning in the known equipment installation work, due to the complex process of equipment centering and centering work and high precision requirements, it brings great troubles to the construction unit. Alignment and positioning of large-scale equipment is an essential part of equipment installation. At the same time, alignment and positioning of equipment is a repetitive and cumbersome work. It often takes a lot of man-hours to meet the standard for a size. In this era of rapid economic development, whether it is due to the requirements of the owner or the consideration of our own costs, we are required ...
