“竖井对话机”在矿山生产中是井口信号室与井下各中段、卷扬机室、地表调度、压风机室等场所进行对话联系的通讯设备之一。在“鞍钢宪法”的指引下,我矿西岔坑经过反复试验,于1966年初安装投产,又经多次改进,现已比较完善。多年来,使用效果良好,保证了竖井安全生产。兹将该机的电路原理、部件选用、制作方法以及性能特点介绍如下,仅供参考。
“Shaft telephone ” in the mine production is the wellhead signal room and the middle of the underground, windlass room, surface scheduling, pressure blower room and other places for dialogue and contact communication equipment. Under the guidance of the “Anshan Iron and Steel Constitution”, the mine’s Xifengkeng was tested and put into operation in early 1966, and after several improvements, it is now relatively complete. Over the years, the use of good results to ensure the safety of the shaft. The machine’s circuit principle, parts selection, production methods and performance characteristics are introduced below, for reference only.
