摘要
船用起重机海上作业过程中,因悬挂重物的钢丝绳属于柔性件,加上风、浪等海洋环境的影响,使得负载产生摆动。基于起重机海上作业时吊物的摇摆,设计了一种新型船用起重机伸缩套管减摇装置,利用套管的刚性约束来减小吊索的摇摆幅度,套管通过万向力矩运动时,依靠弹簧阻尼来存储释放能量,减少吊重的摆幅。文章介绍了伸缩套管装置的结构和原理,建立船、起重机、伸缩套管的数学模型,利用Adams建立仿真模型并进行运动学分析,结果显示伸缩套管装置具有明显的减摇效果。同时,通过搭建试验平台进行试验,验证了伸缩套管装置在实际应用中也具有显著的减摇效果。
For marine crane in the operation process at sea, due to that the suspension of lifting wire rope belongs to the flexible parts, plus, wind, wave and ocean environment causes the load to swing.A new type of marine crane telescopic sleeve anti-swing device was proposed based on the work condition of crane at sea.The sleeve of the rigid constraints is used to reduce the swing range of the load when the casing is moving through the universal torque structure relying on the spring dampers to store and release energy. By these methods to reduce the swing of load. The telescopic sleeve device was introduced. A mathematical model of the ship, crane and telescopic sleeve is established. The kinematics analysis of the simulation model is carried out by using Adams. verifying the obvious anti-swing effects of the telescopic sleeve device. At the same time, through constructing the experimental platform for actual experiments, it is verified that the telescopic sleeve device in the practical application of also has significant effect of anti-swing.
