Fully hydraulic tunnel drilling rigs for coal mines have excellent performance and long service life, leading the industry in my country's R&D and production base for fully hydraulic tunnel drilling rigs. Tunnel drilling rigs for coal mines are mainly used for drilling gas extraction (drainage) holes, grouting fire extinguishing holes, and coal seams underground in coal mines. 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 field is larger than square meters, and the height is larger than the width. The hydraulic system is a double oil pump system, and the rotation speed and feed pressure of the drilling machine are adjusted. By adjusting the displacement of the variable motor to adjust the rotation speed, a constant rotation speed can be achieved. Power speed regulation. (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 markings and can be operated directly after reading the instructions. No special training is required.
