摘　　要：为了解决两腿钩式索具吊具通用性差、工件的机加工面配合性能变差以及吊点分布不均且定位不可靠等弊端,设计一种挖掘机架专用吊具。介绍该吊具的机械结构和工作原理,并对其特性进行分析。该吊具采用三腿钢丝绳结构,具有起吊平稳、吊点自动均布、适应不同直径的法兰等特点,而且吊钩受力后自动锁紧,吊钩滑块系统的角度自适应,起吊时不损坏法兰加工面。In order to improve the poor versatility of 2 limbs hooked sling, poor performance of workpiece＇ s machined sur- face, uneven sling point distribution and location is not reliable, to design crane for excavator frame. To introduce the crane＇ s mechanical structure and working principle, analyze its character. By using 3 limbs steel wire structure, the crane possesses qualities as steadily lifting, even sling point distribution and adapt to all diameter flange, etc. automatically locked after the hook stressed, automatically adjust the right angle of hook slider system, and don＇ t hurt flange operation surface when lift.
