Description

Marine transfer hoisting equipment Technical Field The utility model relates to the technical field of offshore hoisting equipment, in particular to offshore transfer hoisting equipment. Background Ocean resource development is one of important fields of energy and material supply in the world today, and operation activities such as offshore oil drilling, submarine mineral exploitation, offshore wind power installation and the like are increasingly frequent. In these complex ocean engineering, offshore lifting equipment is used as core equipment and takes on the key task of lifting materials and equipment from transport vessels to a working platform or the sea floor. The marine hoisting equipment is mainly divided into two main types, namely fixed type and floating type according to the structural form and the working characteristics of the marine hoisting equipment. The fixed crane is usually arranged on an offshore platform or a wharf and is suitable for a relatively stable working environment, and the floating crane is arranged on a ship or a floating body and can flexibly move to adapt to the operation requirements of different sea areas. The floating crane is a special device combining the characteristics of a fixed crane and a floating crane, is usually arranged on a ship body or a platform with buoyancy, keeps a relatively stable position through an anchor system or a dynamic positioning system, and simultaneously utilizes a crane boom to carry out hoisting operation, the working principle of the floating crane is based on a mechanical balance principle, and the lifting, moving and placing of heavy objects are realized by adjusting the angle and the length of the boom and the posture of the crane. In offshore crane operation, the balance of load weight is crucial, unbalanced load not only affects the stability of the crane and increases the overturning risk, but also can cause problems of damage to suspended objects, low operation efficiency and the like, however, currently, an offshore fixed type floating crane generally lacks an effective transfer structure in design, i.e. no special device or mechanism is used for balancing the load weight on two sides of the crane. Thus, in view of the above problems, it is necessary for the applicant to design an offshore transfer lifting apparatus to solve the problems. Disclosure of utility model The object of the present utility model is to provide an offshore transfer lifting device to solve the problems mentioned in the background art above.
