Abstract

The invention discloses a floating crane, a multifunctional suspension hook thereof and a multifunctional suspension hook group, wherein, the multifunctional suspension hook comprises a fixed pulley block, a movable pulley block, a guiding pulley block, a suspension hook and a wire rope, and the fixed pulley block is vertically swung using a first shaft pin as a shaft; a guiding pulley block is horizontally swung using a second shaft pin as a shaft; the movable pulley block is arranged below the fixed pulley block, and the suspension hook is installed at the lower end of the movable pulley block; the wire rope winds the guiding pulley block, the movable pulley block, the fixed pulley block, the movable pulley block and the guiding pulley block in sequence. The multifunctional suspension hook provided by the invention can realize horizontal swing and vertical swing in the hoisting plane, and two multifunctional suspension hooks are combined to form a floating crane with the multifunctional suspension hook group, thereby realizing turning over of the large structural piece, simple assembly and few hook changes without auxiliary hanging beams, and facilitating the hoisting work with high efficiency.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a floating crane used for marine engineering installation, a multifunctional hook, and a multifunctional hook set. Background technique [0002] Floating cranes are necessary and important equipment in marine engineering, and are widely used in the installation of offshore platforms, maintenance of derricks, installation of offshore wind power equipment, etc. At the same time, floating cranes are also important equipment for submarine operations. The existing floating cranes are divided into offshore floating cranes and deep sea floating cranes according to their usage. The floating crane used for offshore has a small weight, generally between 1000 and 3000 tons; the floating crane used for installation has a small weight and is mainly used for the installation of large port equipment; while the floating crane used for deep sea operations has a relatively large weight. At prese...
