摘要
斜坡压实在道路安全中扮演着十分重要的角色。在道路的施工过程中,往往施工的环境十分恶劣,因此,对相关机械的要求很高。与此同时,很多使用小型手动压实机、自重或者其他的夯实方法,这些在斜坡压实方面就显得十分无力了,很难实现。考虑到这些后,本文借鉴机器人手臂原理,可以较好地实现斜坡压实。
本文的设计中,主要是参考机器人手臂的连杆原理,设计方案以TY220推土机为主牵引机,在TY220推土机一侧连接压实装置。经过相关结构的运动分析后,了解到振动辊和压实机构的大臂是压实机的重要部件。在本设计中,严格的对振动辊、和相关液压缸以及大臂进行了选型和计算,并且根据材料力学所学的知识进行了相关的校核。由于设计要求主要是对机械系统的设计,所以液压系统只是进行了液压缸的设计和选型。
