【摘要】：通过对国内外海洋工程装备发展现状进行研究,了解目前国内海洋工程装备现状。对全球海洋平台做了详实的市场调研,分析出自升式海洋平台在未来海洋平台市场仍会占据主要位置。悬臂梁是自升式海洋平台性能优劣的关键,滑移装置则是悬臂梁动作实现的保证。本文通过对悬臂梁形式了解,罗列出3种常见的悬臂梁：常规型悬臂梁,XY型悬臂梁,旋转型悬臂梁。并重点对常规型悬臂梁的滑移方式进行研究,通过分析棘爪滑移、销轴滑移、齿轮滑移等3种方式的优缺点,优选出悬臂梁滑移装置的滑移方案。对滑移机构中的连接柱销和滑动销关键承载部件,分别采用了材料力学解析解和有限元数值解,对此类既承受较大弯矩和剪力的连接柱销和滑动销,进行了正应力和剪应力静强度校核。还根据可能需要的实际工况,分析出本装置在生产过程、安装过程、调试过程、后期保养等一些注意事项。
[Abstract]:By studying the present situation of marine engineering equipment at home and abroad, the present situation of marine engineering equipment at home and abroad is understood. This paper makes a detailed market research on the global offshore platform, and analyzes that the jack-up offshore platform will still occupy the main position in the future offshore platform market. The cantilever beam is the key to the performance of the jack-up offshore platform, and the slip device is the guarantee of the cantilever beam action. Through understanding the form of cantilever beam, this paper lists three kinds of common cantilever beam: conventional cantilever beam XY cantilever beam and rotary cantilever beam. Through analyzing the advantages and disadvantages of three kinds of slip modes, such as pawl slip, pin shaft slip and gear slip, the slip scheme of cantilever beam slip device is selected. The analytical solution of material mechanics and the numerical solution of finite element are used for the key bearing parts of the connection pin and sliding pin in the slip mechanism, respectively, for this kind of connection column pin and sliding pin which bear not only large bending moment and shear force, but also the sliding pin. Check the static strength of normal stress and shear stress. According to the actual working conditions that may be needed, some matters needing attention such as production process, installation process, debugging process, late maintenance and so on are analyzed.
