【摘要】：船舶推进装置是船舶建造过程中最关键的质量控制点,直接关系到船舶的适航性,经济性和安全性。目前,针对船舶推进装置的安装及后期校中,都有一套比较完整的工艺流程及施工要点。但是随着船舶大型化,高效化的到来,以及船舶建造技术的不断更新换代,旧有的方案已经不能适应新的造船形式。所以在此以国内外比较通行的阐述方法,结合当前实际工作中出现并改进的技术手段,重新阐述船舶建造中推进装置的安装以及校中。为了满足新形势下提高船舶建造质量,缩短在建船舶占用码头期间的施工周期,保证船舶正常航行过程中动力输出稳定可靠的要求,由此改进重点系泊施工项目成为关键。推进装置的安装及校中施工一直是船舶系泊阶段的重点改进施工项目,其施工很大程度上决定船舶的动力性能,因此推进装置的理论中心线与实际中心线必须尽量重合,即校中施工。这就要求合理分布主机、轴系的各支撑点负荷(即称重),满足推进装置热态使用要求。而在调整的过程中,虽然由于各种不可控因素导致船舶建造精度难与理论相符,但是整个过程是有规律可寻的,并且能够进行一定的提前处理(预处理)。文章以图纸、资料和多年来实际现场施工当中累积的经验及统计的数据为基础,结合现在正在进行建造中的系列船,主要是在大连船舶重工建造的一万箱集装箱船及数条VLCC超大型原油轮为例。描述出来关于推进装置安装校中的方案及规律,并依据安装校中规律总结出快速施工及预处理的方案,满足施工目的。
[Abstract]:The ship propulsion device is the most critical quality control point in the process of ship construction, which is directly related to the seaworthiness, economy and safety of the ship. There is a relatively complete set of technological process and construction essentials. But with the arrival of ship size, high efficiency, and the continuous upgrading of ship construction technology. The old scheme can no longer adapt to the new shipbuilding form. So in this paper, combining with the current practical work and the improved technical means, the domestic and foreign relatively common elaboration methods are used. In order to meet the needs of improving the quality of ship construction under the new situation, the construction period of the period during which the ship is occupying the wharf is shortened. To ensure the stability and reliability of the ship's power output during the normal navigation. Therefore, improving the key mooring construction project becomes the key. The installation of the propulsion device and the construction of the alignment are always the key improvement projects in the ship mooring stage, and its construction largely determines the dynamic performance of the ship. Therefore, the theoretical centerline of the propulsion device must coincide with the actual centerline as far as possible, that is, the construction in the school, which requires the rational distribution of the load of the mainframe and the supporting points of the shafting (that is, weighing). In the process of adjustment, the accuracy of ship construction is difficult to accord with the theory because of various uncontrollable factors, but the whole process is regular. The paper is based on drawings, materials and the accumulated experience and statistical data in actual field construction over the years, combined with a series of ships under construction. For example, 10,000 container ships built in Dalian Shipbuilding heavy Industry and several VLCC super large crude oil wheels are used as examples. The scheme and rules of installation and calibration of propulsion units are described. According to the law of installation and calibration, the scheme of rapid construction and pretreatment is summarized to meet the construction purpose.
