Dth Drilling Rig

Drill hole diameter,mm:105-165

Drill hole depth,m:30

Features:

1.    in the cases of no external resource of compressed air the drill rig can self-propelled travel to other working place with the aid of hydraulic system driven by diesel engine and crawler chassis self-propelling system. Sately reliability and high efficiency in operation, ease of traveling and positioning.

2.    a blade is attached to the front of the drill rig to accomplish leveling and clearing working place. The working table can rotate 360 degree, thus operation will even more flexible.

3.    Advanced hydraulic drive technique is used in crawler chassis traveling system. Because of using this technique regulation and control of the drill rig become even more ease, flexible turn, reliable, operation convenient and stable. In addition the drilling rig also has following advantages: large tractional force, strong climbing capacity, no slipping on muddy road and large passage capacity etc.

4.    Perfect place change and positioning mechanism of drilling frame meets the needs to drill slope holes in all directions.

5.    Full hydraulic drive and control technique is used in the drilling equipment, in accordance with the rock condition and drilling depth all drilling parameters(axial pressure, rotation speed and torque) can be stepless regulation. It is convenient for regulation and control. Drive capacity, working stability and anti-overload capacity of main working mechanisms, such as rotation head and pusher etc. It is increased significantly and mechanical structure of positioning mechanism of whole drill rig and rod installation mechanism etc.

6.    Imported low speed and large torque hydraulic motor is used in the rotary system and direct drive system of retarding mechanism is eliminated, thus structure becomes over more and reliable.

7.    High efficient hydraulic system consists of variable-displacement pump and scale valve, all working parameters are continuously adjustable, and comprehensive control system of drilling parameters can real-time regulate drilling parameters to ensure the drilling working in optimum condition at any time, thus accomplish high efficient and low energy consumption drilling.

8.    Drilling and rig positioning operation can be complete on movable console, thus achieve remote control and multidirectional operation.

9.    High drilling efficiency and low labor intensity is achieved through hole guiding device, hydraulic jointing and removel steel rod mechanism, and automatic-struck drill rod device.

10. Accurate and fixed quantity supplement lubrication oil is achieved through patent electron pulse oil lubrication. Thus DTH hammers life is significantly increased.
