MEASURING METHOD OF DRILLING DISTANCE

摘要

PURPOSE: A method for measuring the boring distance of a hydraulic rock drill is provided to improve the construction efficiency of a tunnel by preventing the boring depth of each hole from becoming irregular. CONSTITUTION: A method for measuring the boring distance of a hydraulic rock drill is as follows. A hydraulic motor and a rotary encoder are installed in a fluid line which supplies fluid to a hydraulic cylinder. A purse signal about the rev count from the rotary encoder to the hydraulic motor is received. The moving distance of a hydraulic rock drill is measured by computing the advanced length of the hydraulic cylinder using the pulse signal.
