复合刀盘中心阀块组件设计特点研究

Research on Design Features of Central Cutter Block Assembly of Compound Cutter

本文介绍了一种在隧道施工中用于开挖隧道的掘进机刀盘中心阀块组件,论述了刀盘中心阀块组件的部件组成、设计特点以及其与刀盘、中心回转接头组件的连接方式和工作原理。实践证明作为中心回转接头和刀盘的过渡连接部件,该中心阀块组件对刀盘仿形刀的润滑和伸缩、磨损检测刀具磨损量的准确监测、刀盘泥材和泡沫注入口的顺畅工作提供有力保障。

This paper introduces a cutterhead central valve block assembly of a roadheader used for tunnel excavation in tunnel construction,and discusses the component composition and design characteristics of the cutterhead central valve block assembly and its assembly with the cutterhead and center rotary joint Connection method and working principle.Practice has proved that as the central rotary joint and cutter disc transition connecting part,the central valve block assembly lubricates and retracts the cutter disc copying knife,wear detection,accurate monitoring of tool wear,smooth work of cutter head mud and foam injection port Provide strong guarantees.
