Multifunctional rail-mounted floating crane

Abstract

The invention relates to a multifunctional rail-mounted floating crane which comprises a U-shaped hull, a lifting system and an intelligent adjustment and control system. The U-shaped hull comprises astem, a left sheet body and a right sheet body, and the left sheet body and the right sheet body are spaced at a certain distance; rails arranged in the length direction of the floating crane are installed on decks of the left sheet body and the right sheet body; the lifting system comprises at least one set of trolley walking mechanisms and lifting trusses, the two ends of each lifting truss arefixedly installed on the trolley walking mechanisms on the left sheet body and the right sheet body, and the trolley walking mechanisms walk on the rails to drive the lifting trusses to move; liftingdevices with a lifting function are installed above the lifting trusses; and the intelligent adjustment and control system controls the trolley walking mechanisms and the lifting devices to move. Inthe lifting process of the multifunctional rail-mounted floating crane, the lifting trusses can move in cooperation with the lifting devices, and the stability of lifting operation is improved; and the multiple sets of lifting trusses can be installed on the rails according to the actual lifting capacity, unit operation and online cooperation can be conducted under control of the PLC intelligent adjustment and control system, and the lifting range is enlarged.

Description

technical field [0001] The invention relates to the technical field of shipboard lifting equipment, in particular to a multifunctional rail-type crane ship. Background technique [0002] Crane ship is a kind of engineering ship for lifting and hoisting operations on water. It is widely used in ports, shipyards and water operation sites. It is mainly used for loading and unloading of offshore structures, equipment hoisting, oil and gas development, maritime salvage and rescue operations. In the 21st century, the ocean has gradually become an important field for global oil exploration. The balance of supply and demand of crude oil in the world is fragile, the demand for crude oil continues to increase, and the supply of crude oil is becoming increasingly tense. The development and utilization of offshore oil and gas resources in various countries has reached unprecedented enthusiasm in recent years. The development of global offshore oil exploration has stimulated the market ...

AI Technical Summary

Problems solved by technology

Floating cranes have small lifting capacity and poor stability; semi-submersible cranes have huge construction investment costs and high operating costs, and because of their large size, they lack flexibility in work; Single-lift lifting systems Poor stability, easy to capsize in case of wind and waves, and no transportation capacity, limited types of lifting marine structures

The common disadvantages of the three lifting methods are: poor stability, limited lifting range, and extremely single function
