研究设计了一种适用于工厂室内复杂环境的管道阀门搬运安装设备，该设备能够搬运不同尺寸规格、不同种类的管道阀门，并在特殊环境中完成辅助安装。本研究针对以下三个问题提出了相应解决方案：(1)为克服复杂的室内环境，设计了一种综合式的移动底盘，其采用麦轮组合及辅助越障轮，提高了设备的越障能力；(2)为适应室内狭窄空间及管道阀门特殊安装位置，设计了一种升降机构，其由垂直升降机构和水平提升机构组成，实现了起重升降，保证了设备的结构紧凑性，同时保证了设备的工作范围；(3)为适应不同种类阀门的装夹，提出一种新型末端装夹机构，其能够快速切换装夹方式及调整尺寸，同时能够对管道阀门姿态进行微调，以实现精确安装。本研究使用ANSYS软件对末端装夹机构进行静力学分析，校核了强度；分析了设备的安装精度及抗倾覆能力，验证了设备的合理性和稳定性。

In this study, a pipe valve handling and installation device for complex indoor environments in factories is designed. The device can handle different sizes and types of pipe valves and assist with the installation in special environments. Solutions for the following three problems are proposed: to overcome the complex indoor environment, a comprehensive mobile chassis in Mecanum wheel sets with auxiliary obstacle-crossing wheels is designed to improve the obstacle-crossing ability of the device; to adapt to the narrow indoor space and the special installation position of the pipe valve, a lifting mechanism consisted of vertical and horizontal lifting mechanism is designed, which ensures the compactness of the device structure and expands the working range of the device; to adapt to the clamping of different types of valves, a new end clamping mechanism is proposed, which allows quick switch of the clamping modes and size adjustments, as well as the fine-tuning of the pipe valve postures to achieve precise installation. The ANSYS software is used to perform the static analysis on the end clamping mechanism and validates the strength. And the analysis of the installation accuracy and overturning resistance verifies the feasibility and stability of the device.
