隧道掘进机悬臂掘进机悬臂掘进机也称作自由断面掘进机,主要使用于软岩层的开挖。是一种开挖与装载一体的隧道施工机械。悬臂掘进机主要由切削机构、装渣机构、运输装置和行走机构等组成。切削机构切削机构由切削刀头、减速器、动力驱动装置及工作臂等组成。切削刀头上的刀具有平行和圆锥两种形式。前者适用于软岩的切削,后者适用于硬岩的切削。为了控制切削岩石时粉
Tunnel boring machine Cantilever boring machine Cantilever boring machine, also known as free section boring machine, is mainly used for excavation of soft rock. Is a kind of excavation and loading tunnel construction machinery. Cantilever boring machine is mainly composed of cutting mechanism, slag loading mechanism, transportation device and traveling mechanism. Cutting mechanism Cutting mechanism consists of cutting head, reducer, power drive and work arm and other components. The cutter on the cutting head has two forms, parallel and conical. The former is suitable for soft rock cutting, which is suitable for hard rock cutting. In order to control the cutting of rock powder
