近年来,矿井隧道掘进中大量使用悬臂式掘进机。就巷道截面形状与尺寸而论,悬臂式掘进机特别适于掘进不同的井下巷道,其经济性与技术性引起人们的浓厚兴趣。随着发动机额定功率的增长,掘进的速度亦不断增大。技术上的完善和控制操作的自动化减轻了操作人员的劳动强度,并且最大限度地减少了故障次数。 具体的技术改进方面有: 1.有线、无线或遥控的电液控制; 2.为减少支架的移架时间,实现支架的标准控制,并以此为条件实现移架的完全机
In recent years, a large number of use of cantilever roadheader in mine tunneling. In terms of the cross-sectional shape and size of the roadway, the cantilever boring machine is particularly suitable for driving different underground tunnels, and its economy and technical interest have drawn people’s attention. As the engine rated power increases, the speed of tunneling has also been increasing. Technical refinement and automation of control operations reduce the operator’s labor intensity and minimize the number of malfunctions. Specific technical improvements are: 1. Wired, wireless or remote control of the electro-hydraulic; 2. In order to reduce the stent moving time to achieve the standard control of the stent, and as a condition to achieve a complete removal of the machine
