Abstract

The invention discloses a method for lifting a downcomer. The method comprises the following steps that: A, a gravity center position of the downcomer is confirmed; B, positions of a main lifting point and an auxiliary lifting point are confirmed according to the gravity center position, and a cross section in which the main lifting point is located is allowed to pass through the gravity center or to shift upward slightly relative to the gravity center; C, a first lifting rope and a second lifting rope are fixedly connected with the main lifting point and the auxiliary lifting point of the downcomer respectively; and D, under the condition that an inclination angle of the downcomer is equal to a preset lifting angle all the time, the downcomer is lifted to the preset height, and is butted between upper and lower end connectors of the downcomer. The method simplifies a lifting technique, improves the lifting reliability, lowers the lifting cost and shortens the lifting time.

Description

technical field [0001] The invention relates to the field of blast furnace hoisting, and more specifically, the invention relates to a method for hoisting a downcomer of a blast furnace. Background technique [0002] During the installation process of the blast furnace, the hoisting of the downcomer is more difficult. Generally speaking, in terms of the length, weight and height of the hoisting components, the downcomer is one of the largest components in the hoisting process of the blast furnace, and its auxiliary components, such as ladders, upper Pipe seat, etc., which further increases the difficulty of hoisting to a certain extent. [0003] Therefore, it is a technical problem to be solved by those skilled in the art to provide a simple and reliable downcomer hoisting method to simplify the blast furnace installation process. Contents of the invention [0004] The object of the present invention is to provide a method for hoisting the downcomer of a blast furnace to...
