Product Features
The fully hydraulic underground core drilling rig stands out for its innovative split design, which not only makes the equipment lightweight and easy to transport and install, but also greatly improves operational flexibility. The core unit head of the drilling rig starts the hydraulic pump through the control system of the explosion - proof motor and power unit, generates hydraulic fluid to drive the motor, and then rotates the main shaft, and makes the hydraulic cylinder chain work through the multi - speed mechanism, achieving efficient drilling feed and rotation. Function. The unique design of its hydraulic chuck can easily complete the clamping and disassembly of the drill pipe. It also has an anti - jamming function, ensuring the safety and reliability of the operation. The sliding function of the derrick and the extension and retraction mechanism of the underground core drill ensure close contact between the derrick and the foundation, thus enhancing the stability of the drill rig. In addition, the up and down swing of the derrick and swing frame allows drilling from multiple angles, increasing drilling flexibility and efficiency. The spindle of the unit head has a wide range of rotation speeds and provides a large rotation torque, allowing the drilling rig to cope with various complex geological conditions and ensuring the efficiency and success rate of drilling operations.
