Frequent loading and unloading drill pipe will lead high labor intensity and potential safety hazard for the workers when drilling in coal mine underground.In order to solve this problem, a high-accuracy electro-hydraulic proportional control hydraulic system was designed with high explosion-proof degree according to mechanical structure and required function of the automated drill pipe transportation equipment.The power,control elements and hydraulic principle of the hydraulic system were defined by calculating the pressure and flow of each actuator according to its load,speed and action requirements in the equipment.In order to test the hydraulic system,a hydraulic system prototype of the automated drill pipe transportation equipment was made according to the hydraulic principle diagram.The experiment result shows that the prototype can transfer the drill pipes from silo of the transportation equipment to the case of the drilling machine and meets the work needs of drill pipe transportation equipment.
