. Configuration of main components

The XZ680 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.

The NTA855 turbocharged engine supplied by Chongqing Cummins Company is adopted, which has a strong power and a rated power up to 250KW, saves fuel and is fitted with the potent water radiator, ensuring its long service period.

 

The power unit is directly driven by the low-speed and high-torque hydraulic motor. It is compact, efficient and capable to adjust the high and low speeds continuously so that it is suitable for various work conditions. The power unit is fitted with damping device so that the drill stem threads are protected effectively.

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.

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. The distance between front and rear vices is adjustable.

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 ergonomic and air-conditioned cab with wide vision field and comfortable to operate.

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.

The closed circuit control system is used for power unit circuit and the load sensing control system is used for pushing, pulling, travel and slurry. The hydraulic system adopted is advanced, highly efficient and economical. The imported hydraulic elements are adopted, ensuring the high reliability of products.

The 600L large-flow slurry pump provided by Hengyang Prospecting Machinery Works is fitted. This pump is a horizontal three-cylinder and single-acting reciprocating piston pump which is driven hydraulically.

 

. Optional parts for users

The petroleum drill stem produced by Shanghai Bao Steel, Bohai Nkk and other producer can be selected. The cutting-type or squeezing-type expansion head with a diameter of 400mm~1000mm can be selected.
