Abstract
In view of the low efficiency of rescuing trapped people in coal mine accidents, the factors affecting rapid drilling are analyzed. Through the modular and intelligent technology of rescue vehicle drilling rig, a kind of intelligent wellhead platform drilling tool is developed. The wellhead platform has the functions of automatic levelling and automatic screwing and unloading of drilling tools, and realizes the efficient centering, clamping and automatic screwing and unloading functions of all kinds of diameter drilling tools. The automatic levelling of the intelligent wellhead platform adopts the closed-loop control strategy, the dynamic automatic levelling of the wellhead platform, and the automatic screwing and unloading device adopts program control, which realizes the automatic unloading of drilling tools with one button. The intelligent wellhead platform can be quickly assembled with the main engine, saving drilling auxiliary time, and is of great significance for underground rescue in coal mines.
