Embodiment Construction

[0022] The preferred modes of the present invention will be described in further detail below in conjunction with the examples.

[0023] A method for relay hoisting a gas cooler, comprising the following steps:

[0024] S1. Construction preparation

[0025] First use the three-dimensional technology to simulate the hoisting space to obtain the position of the steel structure avoidance components, then dynamically adjust according to the three-dimensional simulation, prepare the corresponding wire ropes, pulley blocks and hoists, and finally clean the ground of the site where the hoisting will be carried out, and remove the steel structures that need to be avoided. The structure is demolished.

[0026] S2. Setting of hoisting point, winch and pulley block

[0027] Such as figure 1 As shown, first set the first lifting lug 2 and the second lifting lug 3 on the gas cooler 1 to be hoisted for the gas cooler 1 to move horizontally, and the horizontal distance between the first l...

Abstract

The invention discloses a relay hoisting method for a gas cooler. The method comprises the following steps: S1, preparation for construction; S2, settings of a hoisting point, a winch and a pulley block; S3, hoisting of a gas cooler; and S4, recovery of a steel-constructed platform. According to the technical scheme, requirements on the structure of original factory buildings are low; large area of the steel structure is not demolished; and mechanical use is less. Requirements on machinery, cooperation, steel structure welding and the like are high. For an integral hoisting, efficiency is relatively high; investment is saved; actual hoisting time is short; and practicality is strong.

Description

technical field [0001] The invention belongs to the field of equipment hoisting, in particular to a method for relay hoisting of a gas cooler. Background technique [0002] With the rapid development of my country's metallurgical industry, the quality of steel is getting higher and higher, and the amount of high-quality steel is increasing, which promotes the update of refining technology outside the steelmaking furnace. RH (that is, vacuum cycle degassing) system equipment is a secondary refining process equipment for molten steel, which is mainly used to produce high-quality steel. Vacuum system equipment includes vacuum pumps, main exhaust pipes, gas coolers, water-cooled elbows, hot elbows, vacuum tanks, etc.; the gas coolers are arranged on the first floor platform of the converter span, between the first floor and the second floor The clearance is 8.5m, and its volume is generally 4100mm×15.5m, weighing more than 32 tons, large in size and heavy in weight, cannot be...
