【技术实现步骤摘要】
一种八连杆工作装置
本技术属于工程机械领域,具体地说,尤其涉及一种八连杆工作装置。
技术介绍
目前,传统的八连杆工作装置存在以下问题:1、软土工况下挖掘作业时,因铲斗不能实现完全倒扣,发挥不出铲斗的最大固定效果,导致铲斗抓地能力差;2、因传统的八连杆上下运动的平顺性较差,导致铲斗倒扣支撑地面时,为保证铲斗前后边缘同时触地,需要重新调平铲斗,使操作更复杂;3、为实现铲斗倒扣功能,现有技术中将转斗油缸制作的很长,导致油缸压杆稳定性很差;4、因八连杆提升平顺性不足,导致铲斗举升时容易前后洒料;5、将工作装置改为平叉举料时,同样存在提升平顺性不足情况,导致平叉举升平稳性差;6、传统的八连杆工作装置无法兼容合适的管路走向,导致液压管路复杂,胶管弯曲曲率过大,胶管寿命低。
技术实现思路
本技术的目的在于克服上述缺陷,提供一种八连杆工作装置,其液压管路布置简洁顺畅,转斗油缸设计合理,油缸压杆稳定性强,大大提高了工作装置在提升及倒扣时的平顺性。所述的八连杆工作装置,包括车架,车架上设有安装座,安装座上端与动臂一端铰接,动臂另一端与工作装置铰接,动臂中部与安装座下端之间铰接有动臂油缸,动臂 ...
