Horizontal directional drilling rig is a construction machine that lays a variety of underground utilities (pipes, cables, etc.) without excavating the ground surface. It is widely used in flexible pipelines such as water supply, electricity, telecommunications, natural gas, gas, and oil. In paving construction, it is suitable for sand, clay, and other ground conditions.
The composition structure of the horizontal directional drilling rig is as follows:
Directional control system of horizontal directional drilling rig: 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 forms of hand-held wireless and wired direction control systems that are often used.
Horizontal Directional Drilling Rig System: It is the main body of drilling operations and dragging operations through equipment. It is composed of a main drilling rig, a turntable, etc. The main drilling rig is placed on a drilling frame to complete drilling operations and dragging operations. The turntable is installed at the front end of the main machine of the drilling rig, connected to the drill rod, and by changing the rotation of the turntable and the output speed and torque, the requirements of different operating conditions can be met.
Horizontal directional drilling tools and auxiliary tools: various tools used in 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 tools include snap rings, swivel joints and drag heads of various pipe diameters.
Horizontal directional drilling rig mud system: The mud system consists of a mud mixing tank, a mud pump and a mud pipeline to provide the drilling rig system with mud suitable for drilling conditions.
Horizontal directional drilling rig 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.
