Trenchless Construction Directional Boring Equipment Horizontal
Main component configuration
DL660 horizontal directional drilling machine is a horizontal directional drilling device for one machine. Main machine
There are chassis, power head, drill rack, power station, vice, cab, car crane, hydraulic system, electricity,Gas system and other components.
1 ,Chassis
The chassis mainly consists of main frame and left and right walking device. The rear end of the frame is provided with a hydraulic support leg.
The reducer is selected from Dongming Doosan or South Korea's first hydraulic planetary reducer (including motors).
The output torque is large and the structure is compact. The use of wire walking, transition loading and machine adjustment, convenient and safe.
2,Power station device
The system consists of a diesel engine, a hydraulic pump, an overflow valve, a hydraulic oil tank, a diesel tank and a valve block
Assembly, accumulator assembly and so on.
The power station is powered by a diesel engine and hydraulic pumps are provided for the hydraulic system. High pressure oil is the core part of the rig.
Dongfeng Cummins engine is used, the total power is 194kW.
3, power head
The power head rotation is driven by a motor and a speed reducer. It has high and low two bit drilling speed and stepless regulation work. it can adapt to different working conditions.
