lw lw 关于54000T大型散货船舱口盖建造及其端铰链处公差控制的探究 摘 要 舱口是船舶货物装卸的必经通道。舱口盖（Hatch cover）则是船舶用的密封货舱口，保证船体水密性的重要设备。为了提高运输效率，减轻劳动强度，同时也能承受甲板货物的负载，现代传播均采用机械舱口盖。本文以54000T大型散货船为例介绍其舱口盖建造方案和建造时精度控制所采取的一系列的措施，在对舱口盖建造各阶段予以阐述的同时，尤其是对该舱口盖中端铰链处公差的控制着重进行阐述，通过生产过程中的不断摸索和总结，改进思路，改善方法，从而保证了整体的建造质量和生产工期，取得了可喜的成果，并为日后大型舱口盖的建造提供的宝贵的经验。 关键词 散货船 舱口盖 铰链 公差 精度  Abstract The ship is loading and unloading of channels. The Hatch cover (care) is the Hatch cargo ship, with the seal of the important guarantee hull watertightness equipment. In order to improve the transportation efficiency and relieve labor intensity, also can withstand the deck cargo load, modern communication adopts mechanical hatch. Based on 54000T large bulk is introduced the construction scheme and build the hatch cover when the control accuracy, a series of measures to hatch built in stages are expounded, especially for the hatch cover in place of the hinge on tolerance control, through the process of production and fumble ceaselessly, improve method, improvement ideas, so as to ensure the construction quality and the whole production period, and achieved great result for the future, and the construction of large hatch cover provided valuable experience. Keywords bulk carrier hatch cover hinge tolerance precision 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc263597749 1 引言 PAGEREF _Toc263597749 \h 1 HYPERLINK \l _Toc263597750 2 54000T级舱口盖制造的准备阶段 PAGEREF _Toc263597750 \h 1 HYPERLINK \l _Toc263597751 2.1放样及下料的要求 PAGEREF _Toc263597751 \h 1 HYPERLINK \l _Toc263597752 2.2胎架制作 PAGEREF _Toc263597752 \h 2 HYPERLINK \l _Toc263597753 2.3 矫正平台的建造 PAGEREF _Toc263597753 \h 2 HYPERLINK \l _Toc263597754 2.4 舾装平台 PAGEREF _Toc263597754 \h 2 HYPERLINK \l _Toc263597755 3 54000T级舱口盖装配工艺 PAGEREF _Toc263597755 \h 3 HYPERLINK \l _Toc263597756 3.1制造方法 PAGEREF _Toc263597756 \h 3 HYPERLINK \l _Toc263597757 3.2 结构的预装与一般要求 PAGEREF _Toc263597757 \h 3 HYPERLINK \l _Toc263597758 3.3 舱口盖大梁的组合 PAG
