Method for hoisting Fischer-Tropsch synthesis reactor by taking gantry crane as main crane and achieving tail lifting through single gantry

Abstract

The invention relates to a method for hoisting a Fischer-Tropsch synthesis reactor by taking a gantry crane as a main crane and achieving tail lifting through a single gantry, and belongs to the installation field of chemical production equipment. The method includes the following steps that (1) the head of a barrel of the Fischer-Tropsch synthesis reactor is lifted through hydraulic lifters of the main crane step by step, the tail lifting gantry follows main lifting actions cooperatively, and then the tail of the barrel of the Fischer-Tropsch synthesis reactor is lifted and conveyed forwards; (2) in the sliding process of the barrel of the Fischer-Tropsch synthesis reactor, the ascending speeds of the two sets of hydraulic lifters of the main crane are controlled to keep consistent; and (3) along with continuous lifting actions of the hydraulic lifters of the main crane, continuously forward lifting and conveying are conducted through the tail lifting gantry. According to the method, construction cost is low and safety is achieved.

Description

technical field [0001] The invention belongs to the field of installation of chemical production equipment, and in particular relates to a method for hoisting a Fischer-Tropsch synthesis reactor using a gantry crane as the main hoist, and a single gantry with a sliding tail construction. Background technique [0002] At present, the Fischer-Tropsch synthesis reactor is mainly lifted by QMYF6400 hydraulic compound crane. The hoisting technical parameters of the Fischer-Tropsch synthesis reactor are: weight 2,260 tons, diameter 9.6 meters, length 61.5 meters, the hoisting capacity margin is very large, and there are certain constraints in the on-site assembly period of the gantry crane, mechanical coordination, and personnel coordination. waste. [0003] The traditional way of tailing is to use large crawler cranes. For Fischer-Tropsch synthesis reactors, it is necessary to use crawler cranes of more than 1,000 tons to meet the hoisting requirements. Due to the high transfer ...

[0003] The traditional way of tailing is to use large crawler cranes. For Fischer-Tropsch synthesis reactors, it is necessary to use crawler cranes of more than 1,000 tons to meet the hoisting requirements. Due to the high transfer costs of 1,000 tons of crawler cranes, the utilization rate is very low. High construction cost, resulting in waste of resources
