Technical specification sheet

Product model: XZ320 horizontal directional drilling rig

Producer: Xuzhou Xugong Foundation Construction Machinery Co., Ltd

The XZ320 horizontal directional drilling rig has a compact structure and decent appearance. Its main technical performance parameters have reached the domestic advanced level. The main parts and components and corollary parts are of the domestic famous brand and have good performance and reliable quality, ensuring the sound reliability of the whole machine.

. Technical features

Strong power: The 140kW diesel engine ensures that the drilling rig can pave the pipes under various complex ground conditions.

High rotation speed of power unit: The power unit can keep a high rotation speed even though the drilling rig does not decrease its rotating torque and pulling force for pipe paving, so that the high pipe paving efficiency of drilling rig is ensured.

Dual-speed power unit: The low drilling and pulling speed ensures the successful construction. The power unit can accelerate the sliding speed after the drill stem is removed, so that the auxiliary work time is reduced and the work efficiency is enhanced.

Rubber crawler: The influence of this kind of crawler on the road, lawn and sight spot is smallest.

Simple drill stem loading and unloading device: It is helpful to reduce the auxiliary work time and the work intensity of operators.

Floating vice: The proprietary floating vice of the Company shall be adopted, which can prolong the service life of drill stem effectively.

Rotary console: It enlarges the vision filed of operators, reduces their work intensity and makes the drilling rig easier and more comfortable to operate.

Easy maintenance: The reasonable design of engine cap makes it easy to maintain the engine and change the filter element of hydraulic system.

Reasonable system configuration: The rotating, pushing and pulling of power unit and slurry are driven by different and independent hydraulic pump. The hydraulic pump, valve and pipeline are reasonably arranged, minimizing the energy loss.

Wide applicability: The engine is turbocharged so it can boost its power instantly in case of complex ground condition so as to ensure the strong operating power.

Auxiliary booster: The special auxiliary booster can increase the maximum pipe pulling force to 40t so that the work risk is reduced effectively.

. Structure and function of main compositions

The XZ320 horizontal directional drilling rig is an integral device. The machine is mainly composed of the chassis, power unit, drill stand, engine system, vice, hydraulic system, electrical system and other components.

The chassis is mainly composed of the vehicle frame, left and right travel devices. The left and right travel devices can be connected with the vehicle frame by high-strength bolts. The rear end of vehicle frame is fitted with frog-kick hydraulic outriggers. The built-in planet speed reducer (with motor) which has a low running noise, high output torque and compact structure is adopted as the travel speed reducer. The travel mechanism of this machine uses the rubber crawler which has smallest influence on the road surface, lawn or sight spot.

The D6114 supercharged and water-cooled engine provided by Shanghai Diesel Engine Co., Ltd is adopted. The rated power of the engine is 140kW/2300rpm. The oil/water radiator is changed to air radiator. Easy repair and maintenance and high economical efficiency.

The power unit is the main drive of the drilling rig. The input gear of the power unit is driven by four parallel hydraulic motors. The power is transferred to the drill collar through the gear speed reducer of power unit.

The drill stand is welded by high-strength square steel pipes, and its angle is adjusted by cylinder. The pusher and puller of power unit are driven by the hydraulic cylinder.

The vice shall use the proprietary floating vice technology of the Company, which can reduce the wear of drill stem threads and prolong the service life of drill stem.

The slurry pump is a horizontal three-cylinder and single-acting reciprocating piston pump which is driven by a hydraulic motor.

Main control function: Control the engine and its monitoring, slurry pump, vice, rotation acceleration of power unit, pushing and pulling acceleration of power unit, etc. It is composed of the left console, right console, auxiliary console, relay box, various sensor fittings and various instruments, etc.

The hydraulic system driven by gear pump is adopted, which has a strong resistance to pollution. The rotation, pushing and pulling of power unit are driven by different oil pumps so they will not be affected by each other during the pipe paving. The key hydraulic elements are acquired from domestic famous companies, which could improve the product reliability.
