Xz500 Full Hydraulic Horizontal Directional Drilling Rig
The XZ500 horizontal directional drilling rig with the integral and self-loading design adopts various advanced technologies such as the closed energy saving circuit, hydraulic pilot control and load sensing control as well as the proprietary technologies of the Company. Its main performance parameters and control technologies have reached the domestic advanced level. The main components of hydraulic system are of world famous brand and have reliable quality.
I Configuration of main components
The XZ500 horizontal directional drilling rig is an integral device. The machine is mainly composed of the chassis, power unit, and 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 with two speeds adopted make it easy and safe to transfer and adjust the machine among work sites.
2. Engine system
The Cummins 194kW 6-cylinder water-cooled and turbocharged engine is selected. The max. pulling force is up to 500kN under the torque of 18000Nm.
3. Power unit
The power unit is driven by motor and speed reducer and its speed can be adjusted continuously so it is suitable for different work conditions. The power unit is fitted with damping device so that the drill stem threads are protected effectively.
4. Pusher and puller
The pusher and puller offers the feeding force or pulling force to the power unit through the motor, speed reducer and Rack-and-pinion. This mechanism is strong, reliable and stable. The drill stand is easy so slide back and forth to adapt to the drilling angle and gradeability.
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.
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 an air-conditioned cab where the operator and direction controller can work together conformably.
8. Electrical system
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.
9. Hydraulic system
The closed circuit control system is used as the power unit circuit, and the open circuit load sensing control system is used for drilling and pulling, which can save the energy effectively.
II Optional parts for users
1. Drill stem and drill tool
The drill stem produced by Hebei Xuanhua, Wuxi Mineral Exploration Machinery or other producers can be selected. The cutting-type or squeezing-type expansion head with a diameter of 250mm~900mm can be selected.
2. Guide system
The wired or wireless direction control system can be selected.
3. Slurry mixing system
This system is composed of the engine, sewage pump, and slurry tank and swell soil mixer. The capacity of slurry tank can be 3m3 or 5m3 dependent on the user's needs.
Hydraulic system: Various advanced control technologies such as the closed energy saving circuit, hydraulic pilot control and electro-hydraulic proportional control are adopted.
Rotation: Driven by the low-speed and high-torque motor with two speeds.
Pusher and puller: Rack-and-pinion mechanism, with two speeds under continuous regulation, and high working efficiency.
Cab: Single-person air-conditioned cab where the direction control and operating devices are concentrated and comfortable to operate.
Engine: Turbocharged engine with high power reserve, ensuring the drilling power and emergent demands.
Drill stand: High-strength assembled drill stand suitable for drill stems of different lengths; the sliding drill stand facilitates the angle adjustment.
Drill stem holder: The floating holder and on-board crane make the loading and unloading of drill stem more efficient and easier.
Crawler: Self-propelled steel crawler, making the machine easy to transfer.
Wire-controlled travel: Wire-controlled travel, making the machine easy and fast to transfer among work sites.
Monitoring protection: Various parameters of engine, hydraulic pressure and filtration are monitored and warned so that the machine can be protected effectively.
