Tower column type three-chord-member boom ship crane

Abstract

The invention discloses a tower column type three-chord-member boom ship crane. The tower column type three-chord-member boom ship crane comprises a barrel body, a rotary table, a box-shaped stand column and a three-chord-member boom, wherein the barrel body is fixedly arranged on a ship body; the rotary table is arranged at the top end of the barrel body; the box-shaped stand column inclining rearwards is arranged on the rotary table; working mechanisms of the ship crane are arranged in the stand column; the three-chord-member boom is connected with the front end of the stand column; the root part of the boom is connected with the rotary table through a pin roll system; the top end of the stand column, and the position, from the root part to the end part, of the boom are provided with slide wheel systems which are used for winding a steel wire rope of each working mechanism. The tower column type three-chord-member boom ship crane is light in weight, compact in structure, stable and reliable, and reasonable in mechanism transmission.

Description

technical field [0001] The invention relates to the technical field of ships and ocean engineering equipment, in particular to a tower-type three-chord jib marine crane. Background technique [0002] A marine crane is a special crane installed on engineering ships and offshore platforms. It is a construction equipment for hoisting and installing offshore equipment. , luffing mechanism, etc., is an indispensable lifting equipment for large-scale lifting ships. [0003] The special marine environment at sea has brought great challenges to the design of marine cranes, and as the depth of offshore operations increases, the weight of marine equipment increases, making the lifting height of the crane higher, the lifting weight larger, and the operating range Wider, higher requirements for work efficiency, stability, and reliability. Therefore, the structural lightweight and structural stability of marine cranes, such as engineering ships, wind power installation ships and other ...
