Fully hydraulic tunnel drilling rigs for coal mines have excellent performance and long service life, leading the industry. They are the R&D and production base for fully hydraulic tunnel drilling rigs in my country. Tunnel drilling rigs for coal mines are mainly used for drilling gas extraction (discharge) holes and grouting fire extinguishing in coal mines. holes, coal seam water injection holes, outburst prevention and pressure relief holes, geological exploration holes and other engineering holes. Suitable for various coal seams and rock formations with rock solidity coefficients. It is required that the cross-section of the tunnel or drilling site is greater than .3 square meters, the height is greater than .3, and the width is greater than . The hydraulic system is a dual oil pump system. The rotation speed and feed pressure are equal to each other. By adjusting the displacement of the variable motor to adjust the rotation speed, constant power speed regulation can be achieved. (That is, the lower the speed, the greater the torque, and the output power remains unchanged)
By adjusting the displacement of the variable pump to adjust the rotation speed, constant torque speed regulation can be achieved. (That is, the rotational speed changes, but the torque remains unchanged).
The reverse rotation torque of the gyrator exceeds the forward rotation torque, ensuring that the drill pipe thread can still be smoothly unscrewed after drilling with a large torque. The drilling rig is easy to operate. The operation panel has clear and intuitive markings and can be operated after reading the instructions. No special training is required.
