4. Configuration of main components
The XZ3000 horizontal directional drilling rig is an integral device. The machine is mainly composed of the chassis, power unit, drill stand, engine system, vice, cab, on-board crane, hydraulic system, electrical system and other components.
The chassis is mainly composed of the main vehicle frame, left and right travel devices. The rear end of vehicle frame is fitted with hydraulic outriggers. The built-in planet speed reducer (with motor) is used as the travel speed reducer, which has a high output torque and a compact structure. The wired-controlled travel adopted can regulate the speed continuously and make it easy and safe to transfer and adjust the machine between work sites.
4.2. Engine system
The NTA-855 turbocharged engine supplied by Chongqing Cummins Company is adopted, which has a strong power and a rated power up to 392 KW, saves fuel and is fitted with the potent water radiator, ensuring its long service life.
4.3. Power unit
The power unit is driven by imported motor and speed reducer. The power unit has a compact structure and high work efficiency. Its high and low speeds can be adjusted continuously so it is suitable for different work conditions. The power unit is fitted with a damping device so that the drill stem threads are protected effectively.
4.4. Pusher and puller
The pusher and puller offer the feeding force or pulling force to the power unit through the imported motor, speed reducer and rack-and-pinion mechanism. This mechanism is strong, reliable and stable. The drill stand is easy to slide back and forth to adapt to the drilling angle and gradeability.
4.5. Potent drill stem holder
It is composed of the upper and lower vices which operate in accordance with the rotation and movement of power unit to screw up or off the drill stem threads. Driven by the motor, the holder can move back and forth on the drill stand, and the distance between front and rear vices is adjustable.
4.6. On-board crane
The full-rotating telescopic-boom crane truck adopted facilitates the lifting, dismounting and mounting of drill stem and can also be used to lift other drill tools so as to reduce the work load.
The cab is a double-person air-conditioned cab where the operator and direction controller can work together conformably.
4.8. Electrical system
PLC controller is adopted to control all the actions of the drilling rig. Under the control of PLC, the pressure supervision, engine monitoring and various function warnings can match the rotation and power of the engine speed.
It is mainly used to control the functions of rotation, pushing and pulling, vice and travel, etc, and to monitor the parameters and protect the engine and hydraulic system. It is composed of the left console, right console, instrument console and travel control box, etc. The electro-hydraulic proportional valve adopted can realize the stepless speed regulation. The manual emergency system is set.
4.9. Hydraulic system
The circuit, drilling and pulling of power unit use the economic and efficient closed circuit. The imported hydraulic elements are adopted, ensuring the high reliability of products. The independent cooling system ensures that the hydraulic system can work reliably for a long period.
5. Optional parts for users
