horizontal directional drilling machine
Drilling rig system: it is composed of a main drilling rig, a turntable, etc. The main drilling rig is placed on the drilling frame to complete drilling operations and towing operations. 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.
Definition - Horizontal directional drilling is a kind of construction machinery for laying various underground utilities (pipelines, cables, etc.) without excavating the surface.
Application - It is mainly used to lay or renew water supply, gas, electricity, telecommunications, natural gas, oil, sewage drainage and other pipelines under the conditions that are difficult to excavate in downtown areas, cultural relics protection areas, crop and vegetation protection areas, etc.
Introduction - All kinds of horizontal directional drilling machines are composed of drilling system, power system, directional control system, mud system, drilling tools and auxiliary tools.
1. Drilling rig system: it is the main body of the drilling operation and towing operation of the crossing equipment. It is composed of the main engine of the drilling rig and the rotary table. The main machine of the drilling rig is placed on the rig frame to complete the drilling operation and towing operation. The rotary table is installed at the front end of the main machine of the drilling rig, connected with the drill pipe, and meets the requirements of different operation conditions by changing the rotary table rotation and output speed and torque
2. Power system: composed of hydraulic power source and generator. It provides high-pressure hydraulic oil for the drilling rig system as the power of the drilling rig, and the generator provides power for supporting electrical equipment and construction site lighting.
3. Direction control system: The direction control system is a directional tool to guide the drill bit to drill correctly by monitoring and controlling the specific position and other parameters of the drill bit underground through the computer. Because of the control of this system, the drill bit can drill according to the design curve. Currently, there are two types of directional control systems, portable wireless and wired.
4. Mud system: The mud system is composed of mud mixing tank, mud pump and mud pipeline, providing the drilling system with mud suitable for drilling conditions.
5. Drilling tools and auxiliary tools: various tools used for drilling and reaming during drilling. Drilling tools mainly include drill pipe, drill bit, mud motor, reamer, cutting tool and other tools suitable for various geological conditions. Auxiliary tools include snap rings, rotary unions and drag heads of various pipe diameter
