Large-scale pile winding type offshore platform crane revolving platform

Abstract

The invention relates to a large-scale pile winding type offshore platform crane revolving platform which comprises a body. A pile passing hole is formed in the center of the body, front supports are welded on the upper surfaces of the two corners of the front portion of the body respectively, rear supports are welded on the upper surfaces of the two corners of the rear portion of the body respectively, the two front supports are connected through a front cross beam, the two rear supports are connected through a rear cross beam, the front supports and the rear supports are connected through side cross beams, inclined supporting rods are arranged on the lower portions of the side cross beams respectively, and shaft seats used for allowing crane jibs and propeller struts to be arranged are arranged on the two front supports and the two rear supports respectively. A luffing winch mounting platform is welded on the rear portion of the body, a cylinder is welded on the lower portion of the body, a swing mechanism mounting flange is welded on the lower portion of the cylinder, the cylinder corresponds to the pile passing hole, and multiple T-shaped longitudinal reinforcing ribs are evenly distributed on the outer circumferential face of the cylinder. The large-scale pile winding type offshore platform crane revolving platform has the advantages of being compact in structure, low in self-weight and reasonable in stress, and enabling mechanical components to be arranged conveniently.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a large-scale slewing platform of a pile-encircling offshore platform crane. Background technique [0002] At present, with the rapid development of offshore wind power and oil exploration industries, the demand for offshore platforms that use lifting equipment for installation and maintenance is increasing, and newer and higher requirements are also put forward for lifting equipment. Large lifting capacity and large working range have become routine requirements. On this basis, higher requirements are put forward for the effective deck area of ​​offshore platforms, that is, the smaller the deck area occupied by lifting equipment, the better, and even the use of platform structures It does not occupy deck space at all to improve the use efficiency of offshore platforms, and can greatly reduce transportation costs for wind power installation platforms that also serve as transportat...

AI Technical Summary

Problems solved by technology

The slewing platform is used as the main bearing structure load and the installation platform of the main mechanical components (hoisting winch, luffing winch, etc.) of the large-scale pile-wound offshore platform crane. More than 5 meters), it has a very adverse impact on the bearing capacity of the rotary platform structure, brings great difficulties to the structural design of the rotary platform, and at the same time has a certain impact on the layout of mechanical components
