It is mainly used for diamond bit drilling and carbide bit drilling of led.
(1) Rotation unit: Rotation unit (hydraulic drive head) adopted the France technique. It was drive by dual hydraulic motors and changed speed by the mechanical style.
(2) Lifting speed: Rig has the high lifting speed, it can decrease the auxiliary time and improve the rig’s efficiency.
(3) Feeding & lifting: The feeding and the lifting system use the single hydraulic cylinder driving the chain. It has the long feeding distance characters. It is easy for the long rock core drilling process.
(4) Mud pumps: The mud pumps control by the hydraulic valve. All kind of the handle is concentrate at the control set, so it is convenient to solve the accident at the down of the drilling hole.
(5) Reliability: The hydraulic system adopted the France technique, the hydraulic system has the high reliability.
(6) Head mobility: The hydraulic driving head can move away the drilling hole.
(7) Core drilling: Rig has the clamp machine system and the unscrew machine system, so it bring the convenient for the rock core drilling.
(8) Mast stability: The V style orbit in the mast cans sure the enough rigidity between the top hydraulic head and the mast and gives the stability at the high rotation speed.
(9) Spindle stiffness: The rotation unit has the more stiffness spindle, transmission accurately and running steadily, it has more advantages in the deep drilling.
What is the primary application of this hydraulic driving rotation head rig?
It is mainly used for diamond bit drilling and carbide bit drilling of led.
What are the drilling capacities for different core sizes?
The rig supports various capacities: up to 1000m for Ф56mm (BQ), 600m for Ф71mm (NQ), 400m for Ф89mm (HQ), and 200m for Ф114mm (PQ).
What power unit and engine specification does the rig feature?
The rig uses a diesel engine power unit, model 6BTA5.9-C180, delivering 132KW at a speed of 2200rpm.
How does the feeding and lifting system operate?
It uses a single hydraulic cylinder driving the chain. This configuration yields a long feeding distance (4200mm) suitable for the rock core drilling process.
What type of mud pump is integrated, and how is it controlled?
It features a BW-250A three-cylinder reciprocating piston style mud pump. The mud pumps are controlled via a hydraulic valve, with all control handles centralized for convenient operation in handling downhole drilling accidents.
What are the dimensions and overall weight of the rig?
The overall movement dimensions are 8830*2470*3680mm, the working dimensions are 8200*2470*9000mm, and the total weight of the rig is 12400kg.
