管道机器人的设计机械类的毕业论文.doc

摘要
管道运输在我国运用比较普遍,管道长期处于压力大的恶劣环境中,受到水、油混合物、硫化氢等有害气体的腐蚀。这些管道受蚀后,管壁变薄,容易产生裂缝,造成漏油的问题,存在重大安全生产隐患和济济损失。因此研究工程应用中的管道机器人具有很高的实用价值和学术价值。
根据这些问题,我们设计一种新的行走机构并分析了其总体机械结构。本文进一步介绍了当前国内外的管道机器人的发展现状并提出了一种新的管内行走机构。它利用一个电机同时驱动均布在机架上并与管内壁用弹簧力相封闭的六个行进轮,从而实现了可以轴向直进全驱动的管内行走。
接着本论文重点对直进轮式管道机器人的运动机理和运动特征进行了分析和介绍。根据管道机器人的设计要求选择电机,介绍了电机选择过程,对其中关键的机械部件如蜗轮蜗杆传动部件、齿轮等进行了设计。该机器人具有较大的承载能力,可以在较高的速度下实现连续移动,由于该机构采用弹性装置支撑,所以该机构的管径适应性增大,是一种具有实用价值的移动机构形式。

Abstract
In our country, pipeline transportation is very universal, and pipeline is in high pressure circumstance. Because pipes are corroded by the water, the oil mixture, the hydrogen sulfide, the noxious gas corrosion and so on. When these pipelines were corroded, their walls would e thin and result in cracks and oil leak, there is safety incipient fault in production and economic loss. So the key technology and further research development trend of in-pipe robot are discussed.
According to these problems, we designed a new mobile mechanism and analyzed its machine structure. In this paper, the current states of in-pipe robot are described and a new type of mobile robot mechanism moving in pipe is presented. It uses two motor to drive six wheels which distribute symmetrically on the robot body and a wheels are pushed on the wall of pipe by spring force,so that the six driving wheels move along the axis of pipe. This kind of mobile robot mechanism has high efficiency,simple structure and easy to manufacture and to mount.
Then the papers focus on direct pipeline into the wheeled robot's movement and the movement of an analysis and presentation. According to the pipeline robot design requirements choose Motors, introduced the motor selection process, of which the key ponents such as worm transmission parts, such as a gear design. The robot with the larger carrying capacity, can achieve higher speeds for mobile, as the agencies adopt a flexible device support, the agency increased the diameter of adaptability, is a kind of
