摘要

In the drilling engineering of underground drilling rig in coal mines, drill rods are usually loaded and unloaded manually, which has low safety and high labor intensity and restricts the development of underground drilling rigs to the direction of intelligent control. This paper analyzes the problems existing in the loading and unloading drill rods of drilling rigs in coal mines and develops the automatic device for loading and unloading drill rods. The control cores of the device are explosion-proof intelligent controller, electro-hydraulic proportional multiple directional control valve, sensors, and portable remote control. By loading drill rods in the wheeled warehouse, the mechanical arm of the device automatically grabs the drill rods from the wheeled warehouse, and places the drill rods to the fixed position of the drilling rig. and the drilling rig is operated to realize the screwing and unscrewing. The test shows that the device has the characteristics of convenient operation, safety, reliability, and provides technical support for the intellectual development of underground drilling rig in coal mines.
