Method for hoisting rolling mill housing

Abstract

The invention discloses a method for hoisting a rolling mill housing, which comprises the following steps: 1), before the rolling mill housing is hoisted, a housing support frame is fixed on a roll change carriage rail of a rolling mill; a stop block is arranged at the end, far away from the bottom plate of the rolling mill, of the roll change carriage rail; an inclined support panel is arranged on the housing support frame; sleepers are mounted on the bottom plate of the rolling mill; and the rolling mill housing in an inclined state is hoisted to the roll change carriage rail of the rolling mill in such a manner that the central line of the rolling mill housing is superposed on that of the rolling mill, the bottom of the rolling mill housing falls on the sleepers, and the upper part of the rolling mill housing falls on the inclined support panel; and 2), a sling is arranged at the upper end of the rolling mill housing; and the rolling mill housing is hoisted to be vertical and then hoisted to a preset position on the bottom plate of the rolling mill horizontally through a crane, and falls on the bottom plate of the rolling mill, so as to hoist the mill housing in place. According to the invention, the problem that the hoisting of the main hook of a crown block equipped in a construction site is insufficient can be solved, so as to ensure safe, smooth and reliable hoisting.

Description

technical field [0001] The invention relates to a method for hoisting machine parts, in particular to a method for hoisting a rolling mill archway. Background technique [0002] The hoisting of the rolling mill archway is a key process in the installation process of the rolling mill. Due to the insufficient lifting height of the main hooks of the cranes equipped with some unit workshops, the crane cannot be used to vertically hoist the rolling mill archway during the construction of the rolling mill archway, so that the rolling mill archway can be hoisted in place at one time . Contents of the invention [0003] In order to solve the technical problems existing in the known technology, the present invention provides a method for hoisting the rolling mill archway. The method can use the crane main hook equipped on the construction site to lift the rolling mill archway when the hoisting height of the main hook of the crane equipped on the construction site is insufficient. ...
