摘 要：过桥装置是一种非常重要的安全设备,通常安装在铺管船或钻井平台上。过桥装 置主要用于海洋工程设施间的人员通行,还可以用来支撑燃油、水、泥浆等输送管线。 着落锥系统为过桥装置的整体提供着陆一端的支撑结构，并对整个过桥起到一个稳定 和缓冲的作用。本课题主要研究的是 24T 重载的过桥系统的着陆锥的机械结构设计， 液压系统的设计和电气感应控制的设计。机械机构中的支撑力的提供和缓冲需要与液 压系统相结合来处理，而着陆锥的四周转动问题是整个机械支撑结构设计的难点问题。 本课题针对着陆锥的顶部转动，底部摩擦，油缸承载等问题进行课题研究，并提出一 系列的设计方案并拿出最终成果，确定为主体为采用开式油缸自吸式液压系统实现着 陆锥系统的着陆和缓冲动作，采用球头球形结构实现过桥的转动动作等从而完成结构 设计，并确定了材料结构的选型，油缸、单向阀、溢流阀等液压元件的选型等；同时 对侧板、支架座、联接座、托架主体结构进行了强度校核等。

Abstract：Gangway is a very important safety equipment, usually installed in pipe-laying ship or drilling platform. The bridge device is mainly used for the people in the ocean engineering facilities, and can also be used to support the fuel, water, mud and other pipelines. Provide a support structure of land terminal landing cone system as a whole bridge device, and to a stable and buffer effect on the whole bridge up. This thesis mainly studies the design of the mechanical structure of the 24T landing system, the design of the hydraulic system and the design of the induction control. It is necessary to combine with the hydraulic system to support the force of the mechanical mechanism, and the problem of the rotation around the landing cone is a difficult problem in the design of the whole structure. This study aimed at the top of the continental cone rotation, bottom friction, research problem of cylinder bearing, and puts forward the design scheme of a series and come up with the final results, determined as the main body for hydraulic system with open oil cylinders self-priming cone system landing landing and buffering action, across the bridge of the rotational movement is realized by using the ball header structures such as to complete the structure design, and to determine the structure of the material selection, oil cylinder, check valve, relief valve and other hydraulic components selection, etc. And check the side panel, bracket, join, bracket main body structure strength and so on.
Keywords: gangway; landing cone; supporting structure; rotational structure.
