The mud pump, winch, and power head all use a variable frequency motor direct drive structure, with the power head and mud pump employing the most advanced rare earth permanent magnet electric direct drive structure. Efficient, energy-saving, and environmentally friendly.
2. The drilling rig adopts a dual-channel design, with hydraulic lifting cylinders driving the power head up and down, achieving pressurization and depressurization as well as floating drilling; during drilling operations, the power head can be opened to clear the wellhead space, using an electric winch, overhead crane, and pulley system to complete the drilling operations. In case of downhole accidents, the lifting cylinder can raise the drilling tools, and it can also work in conjunction with the traveling system to enhance the ability to handle downhole tool accidents.
3. The main drilling rig adopts a trailer structure, equipped with a full trailer hitch for easy relocation. The trailer chassis has four hydraulic legs with mechanical locks on the front, rear, left, and right, allowing for quick leveling after positioning the drilling rig. The base of the rig is equipped with four hydraulic legs to bear the main drilling construction load, and once the rig is raised, it can be quickly leveled. The VFD/MCC cabinet, driller's cabin, and trailer chassis are integrated as a transport module.
4. The rig is equipped with a rod changing manipulator and a small tool winch, enabling unmanned operations for single rod type two-layer platforms.
5. The main winch drum features a labyrinth rope groove, improving rope winding effects and extending the service life of drilling ropes. The main brake uses energy consumption braking, equipped with an anti-overwinding device and hydraulic disc safety brake. Encoders are installed on the drum shaft and main motor to monitor motor operating parameters, as well as wire rope tension and speed in real-time, working with the electric control system to achieve two automatic drilling modes: constant pressure and constant speed, with anti-jamming, hook load, and speed limiting functions during drilling operations.
6. The rope winch is driven by an AC variable frequency motor and is equipped with a servo-driven rope pay-off device, operated centrally by the driller. The electric control system can display the length and tension of the retrieval rope in real-time.
7. The drilling rig adopts a centralized control method, with the hydraulic and electric control system video monitoring and drilling instruments installed centrally in the driller's cabin.
8. The drilling rig uses digital detection technology to remotely monitor data such as hole depth, drill bit position, hook load, drilling pressure, traveling height, pump pressure, pump volume, speed, and torque in real-time.
9. The electric control system of the drilling rig has comprehensive protection and sound-light alarm functions, including anti-collision and anti-drop for the traveling system (intelligent height gauge), winch handle speed limiting, tension limiting, reverse torque low-speed release, motor overload, stalling, and hook overload.
10. Multiple sensors are used to monitor the operating status of the equipment in real-time, including monitoring the temperature of bearings at key locations, hydraulic pressure monitoring of the lifting power head, hydraulic disc brake status monitoring of the direct drive winch, and monitoring the tension of the traveling system during drilling.
