Method for lifting Fischer-Tropsch reactor by 6400t hydraulic combined crane

Abstract

The invention discloses a method for lifting a Fischer-Tropsch reactor by a 6400t hydraulic combined crane. The 6400t hydraulic combined crane consists of a steel frame structure, an electro-hydraulic power system and a computer control system, and is characterized in that the steel frame structure comprises four tower frames, a main beam, connecting beams and a sliding bearing beam, wherein each tower frame comprises a base, standard sections and a top section device; a plurality of superimposed standard sections are arranged between the base and the top section; the sliding bearing beam is arranged on the top section device; the main beam is connected onto the sliding bearing beam by a flexible hinge; the connecting beams are connected with the tower frames. The method disclosed by the invention has the advantages that the problem that a pipe opening collides with a lifting tool of a crane in the lifting process is solved, and the phenomenon that steel stranded wires of main lifting lugs deviate from a safety angle in the pulling and sliding process is avoided.

Description

technical field [0001] The invention belongs to the fields of petrochemical, coal chemical and other fields, and is mainly used for hoisting the Fischer-Tropsch reactor of the oil synthesis device of the coal-to-oil project with an annual output of more than 1 million tons. Background technique [0002] On December 23, 2008, the first 160,000 tons / year coal-based synthetic oil demonstration project in Shanxi Lu'an with independent intellectual property rights in China officially produced oil. On March 16, 2009, Inner Mongolia Yitai 160,000 tons / year coal The oil production project officially produced oil. This means that my country has fully utilized its own core technology to realize coal-to-oil, marking the first barrel of coal-based synthetic oil produced by the national "863" high-tech project and the knowledge innovation project of the Chinese Academy of Sciences, and has achieved the height of industrialization and industry-university-research Combined, it will play an...
