XYX-3 series crawler drilling rig structure is mainly composed of four major components: the XYX-3 drilling rig, drill mast, crawler chassis and accessory tools. The XY-3 drilling rig is mainly composed of the following parts: 1. Winch, 2. Power unit, 3. Clutch, 4. Universal transmission shaft 5. MW525HQ-1 automobile gearbox, 6. Hydraulic control valve, 7. Hydraulic chuck, 8. Gyrator, 9. Vertical feed cylinder, 10. Spindle, 11. Hydraulic oil tank, 12. Frame, 13. Drive retainer, 14. Bottom chassis.
The power unit can be diesel engine or electric motor. Drill mast and accessory tools are optional for the customers.
3.1 frame: angle iron as beam, the middle part is made of angle steel and iron plate welded together. Upon the frame are fixed winch, gearbox and its control valve handles and shield. The main role is to connect winch, transfer case and gyrator together, make compact structure, convenient for power transmission.
3.2 The clutch is single-piece dry friction taper clutch. It is mainly composed of friction plate and pressure plate. Its role is transmission power or uninstall power.
3.3 The transmission transfers rotary motion and change the rotation speed. The input end connect to the clutch and the output end connect to transfer case through the universal coupling.
3.4 Winch is composed of winch shaft, drum, planetary gear frame, inner ring gear, center gear, improve system circle, brake, etc. Winch system can do reduced pressure drilling, lift tool, put down tube, do percussion sampling, set up drill mast, etc.
3.5 The gyrator is mainly composed of spindle box, spindle sleeve, bearing, spindle, big bevel gear seals and oil cylinder. Gyrator’s rotation drives the drive rod and drill tools, and the feed cylinders lift and push the drill tools.
3.6 Transfer case is actually an auxiliary change-speed institutions, with two handles on it. One handle can realize linkage and separation of winch and spindle ; the other handle can change spindle to high speed and low speed.
3.7 Mud pump is mainly composed of pump body, cylinder liner, valve seat, valve cover, piston, piston rod, steel ball and seals, etc. Its main function is to provide flushing mud for drilling work.
