Study on the Technology of Pulling Out the Pin Shaft of Wing Type Arm Seat of Three Arm Rock Drilling Jumbo

对三臂凿岩台车翼式臂座结构形式以及销轴连接形式作了简单介绍。介绍了三臂凿岩台车翼式臂座销轴拔出的新工艺方法,特别适用于一端敞开另一端封闭结构的销轴拔出。文中阐述了销轴拔出的常用技术方法及存在问题,详细论述了新型销轴拔出工艺的操作过程和实现方法,实现了特殊工况下销轴的高效拆解。

This paper briefly introduces the structural form of wing arm seat and pin shaft connection form of three arm rock drilling jumbo. This paper introduces a new technological method of pulling out the pin shaft of wing arm seat of three arm rock drilling jumbo, Especially, it is more suitable for pulling out the pin shaft with an open end and a closed structure at the other end. This paper expounds the common technical methods and existing problems of pin shaft pulling out, the operation process and realization method of the new pin shaft drawing process are discussed in detail,the efficient disassembly of pin shaft under special working conditions is realized.
