Description

Marine crane lifting and releasing anti-swing device for ocean engineering

Technical Field

Background

The crane is a multi-action hoisting machine for vertically lifting and horizontally carrying heavy objects within a certain range, is also called a crane, and belongs to material carrying machinery. Generally, a hoisting machine is composed of a hoisting mechanism, a running mechanism, a luffing mechanism and a slewing mechanism, and necessary metal structures, a power device, an operation control and necessary auxiliary devices. The crane is characterized by intermittent and cyclic movement, and one working cycle comprises the following components: the load-taking device lifts the load from the load-taking place, then moves horizontally to the designated place to lower the load, and then performs a reverse movement to return the load-taking device to the original position for the next cycle. Generally, a crane suspends a load by a wire rope and a hook, is lifted by a hoisting mechanism, and is horizontally moved by a luffing mechanism and a slewing mechanism. Because the steel wire rope belongs to a flexible component, when amplitude variation and rotation movement are carried out, the load can do simple pendulum movement, which can increase the operation difficulty and the time of working cycle. Particularly, for a marine crane, due to the influence of marine environmental factors such as wind, waves and currents, a ship can generate six-degree-of-freedom motions of rolling, pitching, yawing, pitching and heaving, which further aggravates the swinging of a load and hardly enables operation under severe sea conditions. For the problem of swinging of a suspended object of a crane, a Maryland rigging mechanism and a comprehensive compensation device are usually adopted to solve the problem at present, but the mechanism and the control are complex.

An effective solution to the problems in the related art has not been proposed yet.
