Modular general assembly process of floating crane

Abstract

The invention relates to a modular general assembly process of a floating crane. The floating crane comprises a rotary chassis assembly, a winch mechanism, electrical equipment, an arm frame assembly and a propeller strut assembly; a variable-amplitude winding steel wire rope, a main and auxiliary hook lifting steel wire rope, a rigging hook steel wire rope and a cargo stabilizing steel wire rope are arranged between the propeller strut assembly and the arm frame assembly; the general assembly process comprises the steps of final assembly site arrangement, final assembly jig frame arrangement, winch mechanism arrangement, slewing mechanism arrangement, propeller strut installation, boom assembly installation, winding and stringing, mechanism and electrical equipment debugging and floating crane integral hoisting. The process has the advantages that a special technological process and a mounting process scheme are formulated according to each process of modular mounting of the crane, prediction, research and judgment in the aspects of sites, equipment, materials, personnel, schemes and the like are carried out according to modular mounting requirements, and debugging and test run work of a winch mechanism and a slewing mechanism is carried out after mechanical, electric and hydraulic integrated assembly is completed, so that the subsequent debugging period is saved.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to a modular assembly process for a floating crane. Background technique [0002] As countries expand their ambitious goals for green energy, the global offshore wind power market is expected to grow at an annual rate of 13%-15% in the next 20 years. Under the imbalance of huge market demand expectation and current supply capacity, the demand for wind power installation ships will surge. The crane on the wind power installation ship is indispensable as the main hoisting equipment on the wind power installation ship, and the market demand is huge. [0003] At present, the installation process scheme of the domestic wind power installation ship crane adopts the two major components of the slewing chassis assembly and the jib assembly to be hoisted on board and installed separately by floating crane equipment, and then the barge and tugboat are used on the ship to assist in threadin...

AI Technical Summary

Problems solved by technology

[0003] At present, the installation process scheme of the domestic wind power installation ship crane adopts the two major components of the slewing chassis assembly and the jib assembly to be hoisted on board and installed separately by floating crane equipment, and then the barge and tugboat are used on the ship to assist in threading. Carry out equipment commissioning work, if the hull of the wind power ship does not meet the installation conditions, the crane cannot be installed

[0004] The above-mentioned process scheme is relatively long for the crane assembly cycle, and the rope threading and debugging work can only be carried out after the parts are hoisted and installed on the ship, and the rope threading and debugging on the ship increase equipment rental and labor costs
