绞吸船横移绞车改造安装技术方案

横移绞车故障频发，扭矩过小，咬绳现象时有发生，导致船舶生产率下降和钢丝绳维护成本上升。根据相关规范和船舶设计图纸，对横移钢丝绳咬绳问题进行分析，找到其产生的原因。结合新横移绞车主要技术参数和图纸，制定绞车改造安装的技术方案1和2，从避免钢丝绳咬绳现象发生的角度详细论证两种方案中绞车卷筒中心相对桥架中心是否须偏转一定角度的必要性。结果表明，采用技术方案2现场安装新横移绞车后，船舶施工时绞车钢丝绳规则排布，无咬绳现象发生，提升船舶性能。

Installation technology program of swing winch modification of cutter suction dredger

The frequent malfunctions of swing winch,too small torque,and the bitten rope problem occurs from time to time,which cause the decline of ship productivity and the increase of the maintenance cost of wire rope.According to the relevant specifications and design drawings of the ship,we analyze in detail the bitten rope problem of the swing wire,and find out the causes of the problem,formulate the technical schemes 1 and 2 for the reconstruction and installation of the winch combining with the main technical parameters and drawings of the new swing winch,and demonstrate in detail the necessity of deflecting the center of the winch drum relative to the center of the bridge frame in the two schemes from the angle of avoiding the bitten rope problem.The results show that after the new winch is installed on site by technical scheme 2,the arrangement of winch wire rope during ship construction is regular without bitten rope problem,which improves the performance of the ship.
