Brief introduction of hdd boring machine system

Hdd boring machine of various specifications are composed of drilling rig system, power system, direction control system, mud system, drilling tools and auxiliary tools. Their structure and functions are introduced as follows:

3.1 Drilling rig system: It is the main body of the drilling operation and towing operation of the traversing equipment. It is composed of the main drilling rig, turntable, etc. The main drilling rig is placed on the drilling frame to complete the drilling operation and the retracting operation. The turntable is installed at the front end of the main body of the drilling rig, connected to the drill rod, and by changing the rotation of the turntable and the output speed and torque to meet the requirements of different operating conditions.

3.2 Power system: composed of hydraulic power source and generator. The power source is to provide high-pressure hydraulic oil for the drilling rig system as the power of the drilling rig, and the generator provides electricity for supporting electrical equipment and construction site lighting.

3.3 Direction control system: The direction control system is a directional tool to guide the drill bit to drill correctly through the computer to monitor and control the specific position and other parameters of the drill bit in the ground. Due to the control of the system, the drill bit can drill according to the design curve. There are two types of hand-held wireless and wired steering systems that are often used.

3.4 Mud system: The mud system is composed of a mud mixing tank, a mud pump and a mud pipeline to provide the drilling rig system with mud suitable for drilling conditions.

3.5 Drilling tools and auxiliary tools: various tools used for drilling and reaming during drilling. Drilling tools mainly include drill pipes, drill bits, mud motors, reamers, cutters and other tools suitable for various geological conditions. Auxiliary equipment includes snap ring, swivel union and drag head of various pipe diameters.
